TECHNICAL FIELD
[0001] The present application relates to the technical field of hook arm garbage truck, in particular to an adjustable hook arm for hook arm garbage truck. BACKGROUND
[0002] The hook arm garbage truck is also called detachable garbage truck. It is mainly used for collecting and carrying various garbage in municipal sanitation, property management, large factories, mines and other places. The hook arm garbage truck adopts a full hydraulic control operation system, the garbage box and the chassis can be completely separated, has the advantages of reasonable structure, simple operation, stability, high use efficiency, good sealing performance, convenient dumping and the like, and can realize joint operation of one vehicle and multiple garbage boxes, circular transportation and full improvement of the transportation capacity of the vehicle.
[0003] However, the hook arm garbage trucks produced by different manufacturers cannot match the garbage boxes produced by other manufacturers, and the existing hook arm garbage truck hook does not have an adjustable device. Therefore, during use of the hook arm garbage truck, the following problems may occur: 1. It cannot meet the use requirements of matching multiple boxes with one vehicle; and 2. When matching a small number of boxes, the overall height of the vehicle may be too high. SUMMARY
[0004] The technical scheme of the present application is: an adjustable hook arm for hook arm garbage truck, which comprises a large arm and a hook arm, the large arm is a hollow structure, a rectangular tube is fixedly installed in the large arm, a locking hole is arranged at the top end of the rectangular tube, a pull arm is arranged at the bottom of the hook arm, and adjustment holes matched with the locking holes are uniformly arranged on the pull arm in the vertical direction, and the pull arm can slide vertically up and down in the rectangular tube.
[0005] The present application has the following advantages:
[0006] 1. When the hook arm garbage truck is used, there may be multiple different boxes in the same place. By adjusting the height of the hook arm, multiple boxes can be matched with one vehicle, which greatly reduces the cost and improves the work efficiency.
[0007] 2. The present application has a simple structure, and can be easily modified on the existing vehicle, has low production cost, is convenient and fast to maintain, improves the work efficiency, and is beneficial to popularization and use. BRIEF DESCRIPTION OF DRAWINGS
[0008] Figure 1 is a structural schematic view of the present application.
[0009] In the figure: large arm 1, locking hole 2, rectangular tube 3, pull arm 4, adjustment hole 5, hook arm 6. DETAILED DESCRIPTION
[0010] The present application will be further described below in combination with the drawings and examples.
[0011] exist Figure 1 Among them, an adjustable hook arm for a hook-lift garbage truck is provided, which includes a large arm 1 and a hook arm 6. The large arm 1 is a hollow structure, and a rectangular tube 3 is fixedly installed inside the large arm 1. A locking hole 2 is provided at the top of the rectangular tube 3. A hook arm 4 is provided at the bottom of the hook arm 6. Adjustment holes 5 that cooperate with the locking holes 2 are evenly arranged longitudinally on the hook arm 4. The hook arm 4 can slide vertically up and down inside the rectangular tube 3.
[0012] During operation, the height of the pull arm hook 6 can be adjusted as needed, the adjustment hole 5 on the pull arm 4 can be aligned with the locking hole 2, and then the two can be fixed together by the locking pin, which can make it adaptable to different sizes of garbage bins.
[0013] To prevent the pull arm 4 from swaying inside the rectangular tube 3, the size of the pull arm 4 can be set to be the same as the internal space of the rectangular tube 3.
[0014] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
