附 录motor vehicles and the use of additional devicesSelf-loading vehicle arm (also known as hydraulic multi-energy vehicles and fighting for self-loading and unloading trucks) is characterized by separate cargo body fight with the implementation of a goods vehicle and a number of joint fighting operations, the cycle of transport, which can Self-loading dump containers, precast, machine equipment, bulk materials. The use of the car changed a number of operating the previous system under which the motor transport vehicle must be equipped with cranes or loaders, forklifts, loading and unloading as well as the need for workers in many ways, and saved the car and truck loading of the waiting time, increased turnover of motor vehicles and utilization, thus saving a great deal of manpower, material and financial resources to enhance economic efficiency.At present, the arm-type self-loading vehicle mainly used for mining of mineral aggregate loading, transport and dump, factory parts and rough handling and waste dumping, and construction waste from the handling, more clearance for the urban sanitation sector transportation of refuse. Arm as a result of self-loading cargo vehicles and body is separate from the fighting, using fixed-point garbage collection from time to time. Thus, in particular focal point for residents, as well as the market changes with the seasons the amount of waste sites. Dump it and refuse collection vehicles and forklift formula and flip-shaped seal trash dump trash garbage truck with a circular intake compared Yun, can effectively overcome the operation of the secondary dust and noise pollution.Arm-type truck with a low investment and low operating costs, maintenance and convenient, less noise, no secondary dust pollution, etc. Yang. The drawback is the size of the litter bucket, and can not be placed in the narrow streets, while in transit light foam filled refuse to take full advantage of easy self-loading vehicle arm, some cities have begun to establish a centralized garbage removal station, the use of small land transport equipment (such as human dump 3) refuse to focus on narrow streets in the refuse collection points (floor), and then installed in self-loading arm dedicated junk car in the bucket, and then outward through the self-loading dump truck. It solved the problem of narrow streets could not place the issue of special garbage bucket. To address self-loading arm in the process of motor transport issues dusty materials, Special Purpose VehicleNanning has been designed and built two more effective anti-dust materials, additional devices and drivers can be manipulated to drive the entire operating room Process control device shaft. Are presented below.1, the activities of the vehicle hydraulic cargo canopyThis is to prevent the arm of a self-contained hopper car loading and unloading of materials from blowing out of the vehicle cargo canopy.The structure of the device as shown in Figure 1.Its working principle is: to promote the distribution of hydraulic valve joystick , hydraulic oil into the fuel tank on the cavity, the extended piston rod back, while driving the main arm to the car in front of swing in the tarp , under the canopy of the self and the main arm driven by its front-end articulated main arm , so that folding the sheeting under the lotus back then, under the support of opening up, in the cargo box form a closed top of the Ji Flip cover So that is not contained in the transportation field were filled. When the joystick struck the opposite side, the oil into the fuel tank of the cavity, the protruding rod back, while driving the main arm to the car in front of swing, in the sheeting , Peng-rod self-respect and the main arm Under the impetus of sheeting , Peng-rod and the main arm sequence neatly folded in boxes weeks before the edge, the canopy opened, is expected to facilitate loading and unloading cargo. The device structure is simple and easy to use, especially suitable for the shape of the size of cargo bucket inconsistent. Stacker hopper occasions too, such as good use of cover, fighting to prevent the material goods in the transportation out of dust.2, swing-wing self-loading automatic car coverThe new device structure as shown in Figure 2. When the arm-type self-loading vehicle operations, to manipulate the distribution of multi-way valve stem so that the car swings arms back, when Hopper was slowly lifting, at the same time, as the arm and fixed in the frame side on the small pulley gradually widened the distance that the rope the role of the length of stretch, this time through the wire rope to pull pulley and shaft , with the shaft link a fixed rear cover. Then gradually open up. When the pendulum swing back to the largest angle (that is unloaded or loaded Doo Doo), the rear cover has also opened up to the maximum point of view, are not to affect the loading or unloading hopper. Action in the above-mentioned process, as a result of
