Adjustable strut

Abstract

The invention relates to an adjustable strut which is used in mining engineering, various machinery and other fields of engineering vehicles and comprises a fixing circular tube. One end of the fixing circular tube is connected with a fixing plate, the other end of the fixing circular tube is connected with an adjusting handle, a trapezoidal screw is arranged on the adjusting handle, a connecting hole is formed in the trapezoidal screw, a connecting support is arranged on a supporting plate, a bolt hole is formed in the connecting support, and a bolt penetrates the bolt hole in the connecting support and the connecting hole in the trapezoidal screw, so that the trapezoidal screw can be connected with the connecting support. The adjustable strut has the advantages that the expansion stability of the strut is strengthened owing to a double-nut reverse self-locking mechanism, so that the safety of personnel is protected, and loss of the adjusting handle further can be prevented; the rotatable handle can be turned, so that supporting force of the strut can be further increased by the aid of the lever principle, the strut is high in bearing capacity, the operation, repair and maintenance safety under operation conditions with supporting requirements is improved, and cost decreasing and benefit increasing effects can be realized for enterprises.

Description

Technical field: [0001] The invention relates to an adjustable pillar, which is used in mining engineering, more machinery and other engineering vehicle fields, and especially plays an important protective role in ensuring the safety of people and equipment. Background technique: [0002] At present, the support used in mining roadways and vehicle repair and maintenance is a straight (or square) wood for support. One end of the wood is in direct contact with the equipment and other parts that need to be supported, and the other end is In contact with the ground, the force can be vertical. When the operation was finished, several people were needed to take off the support wood that stood up to the mining roadway and the vehicle and take off to complete the dismantling of the support wood. [0003] Generally, the force that the support wood can bear is small, so that the stability is poor, and there is no guarantee for safety. It is mainly manifested in the safety problems o...

AI Technical Summary

Problems solved by technology

[0003] Generally, the support wood can bear less force, so that the stability is poor and there is no guarantee for safety.

It is mainly manifested in the safety problems of mining roadways and vehicle repair and maintenance. It is not sure whether the support wood is really under force and can support the force. In addition, the force direction of the support wood is different. It is stable, and it is accompanied by vibration and swing during the repair and maintenance of mining roadways and vehicles, so that the support wood is easy to slip out of the mining roadway and vehicle support parts or move sideways, which directly threatens the safety of operators and brings great harm to operators and The equipment caused unnecessary harm, which in turn brought huge personal injuries and economic losses to the enterprise
