Abstract

The invention discloses a spanner trolley which comprises a trolley and a hydraulic torque spanner. The trolley comprises a fixed table bottom frame, a moving table bottom frame, a bottom frame working oil cylinder, a walking direction control handle and a spanner support. The walking direction control handle is perpendicularly connected to the outer side of the fixed table bottom frame. The lower portion of the fixed table bottom frame is connected with the inner side of the moving table bottom frame through the bottom frame working oil cylinder, the outer side of the moving table bottom frame is perpendicularly provided with a spanner support, and the hydraulic torque spanner is supported on the spanner support and is in a rotating fixing state in the horizontal periphery direction. The structure is simple and compact, operation and using are convenient and safe, and the using requirement under a large-torque situation can be met.

Description

technical field [0001] The invention relates to a wrench trolley, in particular to a large torque wrench trolley which can be used in occasions requiring relatively large torque. Background technique [0002] Torque wrench, also called torque wrench, is a kind of wrench, which is widely used in assembly and use with strict requirements on tightening process. In some large-scale assemblies, the required torque is relatively large, and an extension arm is usually added to meet the requirements. This inevitably makes the wrench and the extension arm bulky and heavy, and cannot be manually operated. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a wrench trolley with simple and compact structure, convenient and safe operation, and can be used in high-torque situations. [0004] In order to solve the above technical problems, the technical solution adopted in the present invention is: a wrench trolley, including a...
