Abstract

The invention relates to a hoisting fixture, and provides a hoisting device and an arch frame trolley. The hoisting fixture comprises a body, a first clamping piece, a second clamping piece and a locking mechanism; the first clamping piece is rotatably connected with the body, the second clamping piece is fixedly connected with the body, and the first clamping piece and the second clamping piece are oppositely arranged; the locking mechanism is used for locking and stopping the relative movement of the first clamping piece and the second clamping piece, and the locking mechanism comprises a drive plate, a locking part and an elastic piece; the drive plate is rotatably arranged on the body, the locking part is arranged under the drive plate, the elastic piece is arranged between the first clamping piece and the second clamping piece, one end of the elastic piece abuts against the second clamping piece to apply torque to the locking part to move towards the first clamping piece, so thatthe first clamping piece is locked and stopped by the locking part, and the movement of the locking part is restricted by the drive plate. According to the hoisting fixture, the automatic limiting andtight locking are achieved, the structure is simple, the operation is convenient, and the hoisting process is enabled to be safer and more reliable.

Description

technical field [0001] The present invention relates to the field of engineering machinery, in particular to a hoisting fixture, a hoisting device including the hoisting fixture, and an arch trolley including the hoisting device. Background technique [0002] During the excavation of each tunnel, multiple steel arches were erected along the length of the tunnel to prevent the tunnel from collapsing. Due to the large cross-section of the tunnel, in order to meet the requirements, the length of each arch is correspondingly relatively large, and for the convenience of transportation, usually, each arch can be split into multiple arch segments. During the installation and construction of the arch, the arch section is usually grasped and held by the arch trolley and the corresponding manipulator or gripper mechanism, and the arch section is lifted to the position to be installed by the working arm. [0003] The lifting tongs in the prior art cannot be limited and locked, so that...
