Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of environmental protection equipment, relates to a garbage transport vehicle, and in particular to a sensor installation structure in a compression type garbage transport vehicle. Background Art
[0002] With the continuous improvement of living standards, the output of domestic waste is also increasing. The collection, transportation and treatment of domestic waste are also becoming more and more urgent. As a result, a variety of garbage collection equipment and garbage trucks have emerged. Compression garbage trucks are one of them.
[0003] Compression garbage trucks are mainly used for urban garbage collection and transportation. Compression garbage trucks can use the compression device they carry to compact bulk garbage before transportation, effectively increasing the amount of garbage transported each time, effectively reducing the labor intensity of sanitation workers, and saving operating costs. The current compression garbage trucks include structures such as a chassis, a garbage bin, a filler, and a garbage hopper. The filler includes a filler body for accommodating and compressing garbage and a lifting cylinder. The lifting cylinder is extended and retracted to control the lifting of the filler body to complete the compression of the garbage. In order to control the filler body, a sensor is usually set on the beam of the filler body corresponding to the inner side of the end of the lifting cylinder on the left side of the filler body to sense the lifting cylinder. The structural diagram is shown as follows. Figure 1 As shown, the lifting cylinder 1 and the beam 2 of the filler body are arranged at an angle and are parallel to each other. A mounting plate 3 for mounting a sensor 4 is provided between the lifting cylinder 1 and the beam 2 of the filler body. The position sensing end of the sensor 4 is arranged upward, so that the garbage is easily hung on the mounting plate and the sensor during the loading process, and some garbage will fall on the mounting plate and the sensor during each lifting process of the filler, which will not only affect the sensor's sensing signal and reduce the accuracy of the sensor's sensing signal, but also the garbage has a certain corrosiveness, which will affect the service life of the sensor over time. Summary of the Invention
[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a sensor installation structure in a compression type garbage transport vehicle, which can effectively protect the sensor while ensuring the accuracy of the sensor sensing signal and extend the service life of the sensor.
[0005] The technical solution of the present utility model is achieved as follows:
[0006] A sensor installation structure in a compression garbage transport truck includes a lifting cylinder, a sensor and a beam of a filler body. The lifting cylinder and the beams of the filler body are arranged at an angle and are parallel to each other. The sensor is arranged above the lifting cylinder through a mounting mechanism. The mounting mechanism includes a mounting column and a mounting protection box. The mounting protection box is arranged at one end of the mounting column, and the other end of the mounting column is fixed to the beam of the filler body. The plane where the bottom plate of the mounting protection box is located is parallel to the central axis of the lifting cylinder. The sensor is vertically arranged on the bottom plate of the mounting protection box, and the sensing end of the sensor extends out of the bottom plate of the mounting protection box for sensing the lifting cylinder.
[0007] Furthermore, the bottom plate and one side plate of the installation protection box constitute an L-shaped mounting frame, and the remaining three side plates and the top plate constitute a protective cover. The mounting column is fixed to the side plate corresponding to the L-shaped mounting frame, and a hinge is provided between the side plate corresponding to the L-shaped mounting frame and the top plate of the installation protection box, so that the protective cover and the L-shaped mounting frame are movably connected, which is convenient for maintenance or replacement of the sensor.
[0008] Furthermore, the L-shaped mounting frame and the protective cover are respectively provided with connecting ears, which facilitate the connection and fixation of the L-shaped mounting frame and the protective cover through the connecting piece.
[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] 1. The sensor in the utility model is arranged above the lifting cylinder, and the sensor is installed and protected by a mounting protection box, which can effectively prevent garbage from falling on the sensor, thereby avoiding the interference of garbage on the sensor's sensing signal, ensuring the accuracy of the sensor's sensing signal, and also preventing garbage from corroding the sensor, thereby extending the service life of the sensor.
[0011] 2. The mounting and protection box of this utility model consists of an L-shaped mounting frame and a protective cover. The L-shaped mounting frame and the protective cover are movably connected. When the sensor needs to be maintained or replaced, it only needs to unscrew the protective cover, which is convenient to operate. At the same time, the L-shaped mounting frame and the protective cover are respectively provided with connecting lugs to fix the L-shaped mounting frame and the protective cover, ensuring the fixing of the mounting and protection box, thereby effectively protecting the sensor.

[0015] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.
[0016] See also Figure 2 A sensor installation structure in a compression garbage transport truck includes a lifting cylinder 1, a sensor 4 and a beam 2 of a filler body. The lifting cylinder 1 and the beam 2 of the filler body are arranged obliquely and parallel to each other. The sensor 4 is arranged above the lifting cylinder 1 through a mounting mechanism. The mounting mechanism includes a mounting column 6 and a mounting protection box 5. The mounting protection box 5 is arranged at one end of the mounting column 6, and the other end of the mounting column 6 is fixed on the beam 2 of the filler body. The plane where the bottom plate of the mounting protection box 5 is located is parallel to the central axis of the lifting cylinder 1. The sensor 4 is vertically arranged on the bottom plate of the mounting protection box 5, and the sensing end of the sensor 4 extends out of the bottom plate of the mounting protection box 5 to sense the lifting cylinder 1.
[0017] In this way, the sensor is set above the lifting cylinder and is installed and protected by a mounting protection box, which can effectively prevent garbage from falling on the sensor, thereby avoiding the interference of garbage on the sensor's sensing signal, ensuring the accuracy of the sensor's sensing signal, and also avoiding the corrosion of the sensor by garbage, thereby extending the service life of the sensor.
[0018] During specific implementation, the bottom plate and one side plate of the installation protection box 5 constitute an L-shaped mounting frame, and the remaining three side plates and the top plate constitute a protective cover. The installation column is fixed to the side plate corresponding to the L-shaped mounting frame, and a hinge 7 is provided between the side plate corresponding to the L-shaped mounting frame and the top plate of the installation protection box 5, so that the protective cover and the L-shaped mounting frame are movably connected, which is convenient for maintenance or replacement of the sensor 4.
[0019] like Figure 2 As shown, the side panels of the mounting and protection box corresponding to the L-shaped mounting bracket are provided with through-holes for the sensor circuit to pass through. The circuits are connected to the sensor connection terminals provided on the bottom plate of the mounting and protection box. The mounting and protection box here consists of an L-shaped mounting bracket and a protective cover. The L-shaped mounting bracket and the protective cover are movably connected. This allows for convenient maintenance or replacement of the sensor by simply unscrewing the protective cover.
[0020] In specific implementation, the L-shaped mounting frame and the protective cover are respectively provided with connecting ears 8, which are convenient for connecting and fixing the L-shaped mounting frame and the protective cover through bolts 9.
[0021] This prevents the protective cover from vibrating or opening during garbage transport or other circumstances. Bolt fastening is also convenient, and the materials are readily available, further facilitating practical application. In this embodiment, the connecting lugs of the L-shaped mounting bracket and the protective cover are located on the lower side opposite the hinge.
[0022] Finally, it should be noted that the above embodiments of the present invention are merely examples for illustrating the present invention and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations and modifications based on the above description are possible. It is not possible to enumerate all implementation methods here.
