Abstract
Description
Technical Field
[0001] This utility model relates to the field of heavy vehicle rescue, and in particular to a hydraulic demolition tool for heavy vehicle rescue. Background Technology
[0002] Heavy vehicle rescue refers to a series of professional rescue operations taken when large and heavy vehicles are unable to drive normally or are trapped due to malfunctions, accidents, natural disasters, or other reasons while driving or during operation.
[0003] Currently, hydraulic rescue tools are used to assist in the rescue of heavy vehicles depending on the type of damage. However, there are many types of hydraulic rescue tools, and hydraulic spreaders are one of them. A hydraulic spreader is a rescue tool made of high-strength lightweight alloy steel with expansion, tearing and pulling functions. It requires an external hydraulic power system to operate, and the hydraulic cylinder in the hydraulic spreader drives the expansion arm to open and close.
[0004] However, the patent application with publication number CN222075747U in the prior art provides protection by setting up a protective cover during the expansion operation of the hydraulic expander. If the object being expanded breaks during the expansion process, the flying fragments are blocked by the protective cover, preventing the flying fragments from injuring the hand holding the handle. At the same time, a safety support component is set up. When the external hydraulic power system fails, the two expansion arms are supported by support plate one and support plate two in conjunction with the storage groove, preventing the expansion arms from accidentally closing and causing safety hazards after losing the support of the external hydraulic power system.
[0005] However, modern hydraulic spreaders are equipped with handles for easy handling. However, during the use of hydraulic spreaders, different angle adjustments are required depending on the scenario. Fixed handles can cause inconvenience and instability when operators are handling the hydraulic spreaders.
[0006] Therefore, it is necessary to provide a hydraulic demolition tool for heavy vehicle rescue to solve the above-mentioned technical problems. Utility Model Content

[0043] Hydraulic cylinder:
[0044] Composition: It consists of a cylinder, piston, and piston rod. After high-pressure hydraulic oil enters the cylinder, it pushes the piston, which in turn drives the expansion arm to move through the piston rod.
[0045] The annular movable groove 22 and the arc-shaped movable block 23 are used for adjusting the angle of the connecting handle 3.
[0046] The fixing component 4 includes a bracket 41, an annular fixing block 42, a fixing bolt 43, and multiple fixing holes 44. The bracket 41 is connected to one side of the connecting handle 3, and the annular fixing block 42 is connected to the surface of the arc-shaped movable block 23.
[0047] Bolts are provided on the arc-shaped movable block 23, and multiple threaded holes that are compatible with the bolts are opened on the inner wall of the annular movable groove 22.
