Gripper device for disaster relief car

Abstract

The invention relates to a gripper device for a disaster relief car. The gripper device is arranged on a big arm of the disaster relief car, and comprises a pair of oppositely arranged gripper clamp plates, a pair of hydraulic cylinders respectively in transmission connection with the gripper clamp plates on the corresponding sides and small arms hinged to the gripper clamp plates and the hydraulic cylinders, wherein the small arms are hinged to the big arm of the disaster relief car. According to the gripper device, the gripper clamp plates on the corresponding sides are controlled to open or close by stretching of pistons in the hydraulic cylinders so as to grip objects. Compared with the prior art, the gripper device can be directly mounted on big arms of such engineering vehicles as disaster relief cars and excavators to directly finish gripping or executing operation, and has the advantages that smooth falling hillstone can be reliably clamped during gripping and objects can be accurately and stably gripped; the rescue efficiency is greatly improved; the production cost of the special engineering vehicles is lowered; the gripping force is big; the flexibility is excellent; and the effectiveness of such engineering vehicles as the disaster relief cars can be played as much as possible.

Description

technical field [0001] The invention belongs to the technical field of mechanical grippers, and relates to a gripper device for disaster relief vehicles. Background technique [0002] In the past, in disaster rescue, especially in mountainous natural disaster rescue, large excavators were often used to remove road obstacles. However, when removing smooth rolling rocks or logs produced by landslides or debris flows, manual removal methods were often used, which wasted a lot. Precious rescue time. In an urgent and dangerous disaster relief environment, a reliable and effective rescue vehicle grip device can provide great help to rescuers. For the structural design of the gripper device of the disaster relief vehicle, the following points must be considered: first, the gripper device has sufficient grip; second, there should be a certain opening and closing angle between the two jaws of the gripper; The grasped object can be accurately positioned and operated flexibly; fourth...

AI Technical Summary

Problems solved by technology

In the technical solution disclosed in the above-mentioned patent, the gripper can be installed on a multifunctional mechanical device for firefighting and emergency rescue, and it can enter extremely dangerous places for firefighting and rescue operations, working like a robot to reduce casualties and property losses, but the gripper only passes through one The power is provided by the oil cylinder, the grip force of the gripper is small, and the strength, rigidity and flexibility of the gripper are poor, so it cannot effectively remove obstacles similar to rocks or logs
