Description

Technical Field

[0001] The invention relates to the technical field of special sanitation vehicles, and more particularly to a foldable hook arm device for a detachable garbage truck. Background Art

[0002] Hook-arm garbage truck, also known as unloadable garbage truck, is mainly used for collecting and transporting various garbage in various places such as municipal sanitation, property management, large factories, industrial and mining enterprises.

[0003] At present, the existing technology simply lowers the height of the hook from the ground. The total height of the box after it is lifted is still greater than the total height of part of the basement. Moreover, the existing patented technology does not have enough pressure during the loading and unloading process. Sometimes, if there is a lot of garbage, the garbage box cannot be lifted onto the hook-arm garbage truck, and only part of the garbage in the garbage box can be dumped out. Only after the total mass of the garbage box is reduced can the garbage box be re-installed on the truck. Only a few cylinders are involved in the work of the existing device when hooking and unloading goods. When loading and unloading the garbage box, if there is a lot of garbage, the garbage box body cannot be loaded on the truck, or the engine is turned off. This is because the cylinder pressure is too small, so that the vehicle body is unstable, which increases the risk of operation.

[0004] Therefore, how to provide a foldable hook arm device for a detachable garbage truck with a lower height, a larger area and improved safety is a problem that technicians in this field urgently need to solve. Summary of the invention

[0023] In this embodiment, a hook assembly 10 is provided at one end of the folding right-angle arm 9 away from the second folding cylinder 7 .

[0024] In this embodiment, a car body locking hook and a locking cylinder are provided on the auxiliary frame 1; if the locking cylinder is not opened, other key operations will not respond, so as to prevent workers from operating incorrectly.

[0025] In this embodiment, a locking cylinder is provided in the lifting arm 3, and the locking cylinder is connected to the lifting cylinder 4; the lifting cylinder 4 extends and retracts the lock head, and can load and unload the garbage box or the multi-functional garbage box with the second cylinder fulcrum 11 as the center. The locking cylinder in the lifting arm 3 retracts, and the garbage in the garbage box can be self-unloaded and dumped with the first cylinder fulcrum 10 as the center.

[0026] In this embodiment, the center points of the flip bracket 2 and the auxiliary beam frame 1 are at the same axial position, so that the flip bracket 2 can rotate relative to the auxiliary beam frame 1.

[0027] In addition, in this embodiment, one end of the second folding cylinder 7 and the piston rod end of the folding right-angle arm 9 are connected to the eighth cylinder fulcrum 17 through a fixing pin, and the eighth cylinder fulcrum 17 forms the rotation axis of the folding right-angle arm 9;

[0031] The first folding cylinder 5, the second folding cylinder 7 and the lifting cylinder 4 all have a pressure relief function, so that the device can still maintain high-power output when the engine is at low speed, reducing fuel consumption. At the same time, the hydraulic cylinder with built-in pressure relief function has a longer service life, avoids multiple maintenance in the later stage, and reduces the cost of use. The most important thing is that compared with the existing technology, the pulling force is greater and more stable when loading and unloading garbage, which solves the technical problem of insufficient pulling force in the existing technology once too many boxes cannot be loaded on the vehicle, greatly reducing the safety risk.

[0032] Equipped with the assistance of electromagnetic valves and electromagnetic sensors, the garbage containers are more diverse in form and more adaptable to areas with difficult operating spaces.
