Wrecker structure

First, the main structure and working principle:
The JAC wrecker series is derived from the JAC light truck type 2 chassis as a platform. It has the functions of lifting, pulling and back dragging. It is fully capable of carrying out ordinary road rescue and vehicle distribution. The outline of the vehicle is as follows:

1. Power-taking device The power-taking device consists of a power take-off device, an oil pump, and operation buttons. The power take-off device is connected with the automotive gearbox and drives the oil pump to generate high pressure oil for the working conditions of each working part.
2. Sub-frame The sub-frame is a box-shaped structure and welded with high-strength low-alloy steel plates. A flat telescopic cylinder front bracket, a lifting cylinder upper bracket beam, a bracket arm lifting cylinder upper bracket, a boom lifting guide limiting plate, etc. are provided, and two lifting cylinders, a rotating shaft, a flat rotating bracket and a chassis of the automobile are passed through. The connection, with good rigidity and strength, is an important stress component.

3. The flat plate is composed of front and rear two-segment plates. The flat plate is connected by sliding between the longitudinal beam of the flat plate and the longitudinal beam of the subframe, and the two flat plates are connected together through the flat rotating pin assembly, and the connection is firm and the relative movement is flexible; the flat plate is The bottom plate adopts a pattern bottom plate, which can effectively prevent the towed vehicle from slipping on the top.
4, winch mechanism winch mechanism by the hoist, hydraulic motor, wire rope, hook composition. The hydraulic motor drives the hoist to make the wire rope roll up or pull out.
5. The luffing arm The luffing arm is a welded steel structure, which is connected with a supporting arm raising cylinder and a supporting arm lifting cylinder upper bracket, an inner connecting telescopic hydraulic cylinder and a telescopic arm. The prop arm lifter can extend and extend the luffing arm and change its working range. The expansion and contraction of the telescopic cylinder can extend or shorten the telescopic arm, adjust the distance between the fork and the towed vehicle tire, and lock the bracket and the tire. Support driving.
6. The fork support is composed of a rotating arm, a telescopic arm of a supporting arm, a supporting beam of an adjusting arm, an adjusting arm, etc., wherein the relative sliding between the rotating arm and the telescopic arm of the supporting arm is manual, convenient and flexible, and through their relative sliding, The lateral positional relationship between the adjusting arm supporting beams can be adjusted, and the relative movement between the adjusting arm and the adjusting arm supporting beams is also manual. Through the relative movement between them, the longitudinal positional relationship between the adjusting arm and the tire can be adjusted.
7, Toolbox Toolbox for all-metal structure, can be placed a variety of operating tools and accessories
8, hydraulic system Hydraulic system consists of hydraulic pumps, hydraulic motors, hydraulic cylinders, multi-way valve, hydraulic tank and hydraulic lines.
The power take-off drive hydraulic pump draws low-pressure oil from the tank, pumps out high-pressure oil, and manipulates the handles of the reversing valve to realize various working conditions such as winding, luffing, lifting, platform sliding, and platform tilting. A relief valve is attached to the reversing valve to protect the hydraulic system from overloading. The balance valve is connected to the lower end of the platform lift cylinder and the support arm lift cylinder, which can effectively prevent the hydraulic cylinder from generating impact during the downward movement and play a role in maintaining the pressure.

Industrial Fan

Product Profile Large energy saving ceiling fans are green energy saving products of the 21st century. It has many advantages, such as powerful, no noise, zero pollution, low energy consumption. It is very popular for large masses of users. It is not only mainly used in steel structure plant, logistics warehouse, farm and other large enterprise buildings, but also agricultural markets, gymnasiums, waiting rooms, exhibition halls and other large public buildings. A large energy-saving ceiling fans with a speed of 50 revolutions per minute 1 to 3 meters per second to make the human body feels the best wind speed. A breeze from all directions gently caresses the body and increases the evaporation of human sweat. The cooling effect of 5 to 8 degrees is similar to the comfort presented by the natural breeze, which can not be matched by other fans. It is an ideal choice for indoor, ventilation and cooling in summer to remove humidity and heat. Only seven degrees of electricity per day, it can be cool for a whole summer. Energy saving comparation In summer, the sun shines directly and the indoor temperature is more than 40 degrees on average. Common industrial exhaust fans can only increase the indoor temperature. Industrial air conditioners consume thousands of kilowatts of energy every shift. There is no obvious unenclosed cooling in the space, which also increases the operating cost of enterprises. The emergence of a large energy saving ceiling fan brought the perfect solution. An energy saving fan with a diameter of 7.2meters can push the air to produce a large amount of winds effectively. The continuously rotating blades of circular form an airflow field with an effective area of 600 to 800 square meters. No other device has not yet been compared. The large energy-saving ceiling fan praduced by Linter technology has the characteristics of high reliability, feasibility and low power consumption. The controller unit used the stability of the energy-saving inverter system. In practice, the average power consumption is less than one killowatt per hour. It can guarantee more than 5,000 hours of uninterrupted operation. Linter7200 of a large energy-saving ceiling fan can cover the area of about 50 small fans of 0.75 megabytes worked. In a factory of 9000 square meters, if full coverage is to be achieved, it needs about 300 small fans or industrial 6 energy-saving fans. According to the use of four years, every eight months, every day for ten hours, can be run for 10,000 hours, about 90000kw power consumption, than the small wind 1080000kw, save 990000kw, save energy by 92%. When meeting the extreme high temperature climate, the large energy saving fans and air conditioners are used together, it will be coller. Using A large energy-saving ceiling fan for air supply can not only save the air conditioning tube, but also save more than 30% energy. Attentio Lectotype The building structure: H-shaped steel, I-shaped steel, Mixed steel square bar spherical column spherical structure. The total height of the building is more than 4, 0m, less than 15m. 1, 0m. The minimum distance between the fan and the roof is 1, 0m. The minimum safety distance between the fan blades and the obstacle is 0, 3 m. The distance between the fan blades and the wall on both sides is more than 1, 5 m. Effects of various environments on fan performance. Open space, promotes air circulation. Indoor airflow circulation in enclosed spaces is suitable for use with air conditioning. In a multi-fan environment, due to the low wind speed, caused by the fan, there will be no cyclones. The distance between the two fans will be separated before the wind will not cancel, and the coverage area will be increased at the same time.
