Lifting vehicle

Abstract

The invention provides a lifting vehicle which comprises a walking device, a lifting device, an operation table, a first arm, a second arm and a limiting device, and a first platform is arranged at the top of the walking device; the lifting device is arranged on the first platform and comprises a lifting assembly and a second platform, and the lifting assembly is arranged between the first platform and the second platform; the operation table is rotatably arranged on the second platform and is provided with a first position and a second position; a first bracket is arranged at one end of the first arm, the other end of the first arm is assembled on the second platform and can swing towards one side of the lifting vehicle, a second bracket is arranged at one end of the second arm, and the other end of the second arm is assembled on the second platform and can swing towards the other side of the lifting vehicle; the limiting device comprises a guide rail and a clamping piece, the guide rail is arranged on the second platform, and the clamping piece is arranged on the guide rail and can move in the extending direction of the guide rail. According to the lifting vehicle, the mine shed erecting operation is facilitated, the labor intensity of workers is reduced, and the mine production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mine scaffolding operation equipment, in particular to a lifting vehicle. Background technique [0002] In recent years, with the increase of coal mine mining depth, roadway roof conditions have become more and more complex. In order to prevent roof collapse, it is necessary to perform scaffolding operations on positions with poor roof conditions and developed roof cracks. In the related art, the scaffolding operation mostly adopts the form of manual operation. [0003] During the scaffolding operation, it is necessary to manually move the scaffolding materials to the body of the bolter, due to factors such as the narrow space of the underground roadway, heavy scaffolding materials, no suitable station for high-altitude operations, more labor, and greater labor intensity , When the bolter miner cooperates with the shed, on the one hand, there are a large number of operators, and on the other hand, improp...

Problems solved by technology

[0003] During scaffolding operations, it is necessary to manually move the scaffolding materials to the body of the bolter miner. Due to the narrow space of the underground roadway, heavy scaffolding materials, no suitable station for high-altitude operations, more labor, and greater labor intensity, etc. , When the bolter is used with the shed, on the one hand, there are a large number of operators, and on the other hand, improper equipment operation and coordination can easily cause personal injury and there are safety hazards such as falling objects and injuries. Secondly, each time the shed is built takes a long time , affect the normal excavation, and the bolter cannot be overhauled normally, especially when the potential failure of the equipment occurs at the same time as the scaffolding operation, it will seriously restrict the production, which is not conducive to the safe and efficient implementation of the scaffolding operation
