Magnetic adsorption device for climbing trolley

Abstract

The invention discloses a magnetic adsorption device for a climbing trolley. The magnetic adsorption device comprises a vertical plate, a moving assembly, a magnet mounting plate and a connecting rod, wherein the moving assembly is installed on the vertical plate, and the moving assembly can move in the direction close to and away from the vertical plate; one end of the magnet mounting plate is rotationally connected with the vertical plate, the other end of the magnet mounting plate extends in the direction away from the vertical plate, and a magnet is arranged on a bottom surface of the magnet mounting plate; one end of the connecting rod is rotationally connected with the moving assembly, and the other end of the connecting rod is rotationally connected with the magnet mounting plate.

Description

technical field [0001] The invention relates to the technical field of climbing equipment, in particular to a magnetic adsorption device for a climbing trolley. Background technique [0002] At present, in the prior art, the way to mount the magnet on the wall-climbing trolley includes setting the magnet on the bottom plate or setting the magnet on the fixed plate, and the fixed plate is set under the bottom plate. Under some special working conditions, when the trolley is in In the upward position, the suction force may be insufficient and the device may fall. [0003] In addition, one end of the fixed plate can be hinged on the wheel shaft, and the other end is free, and auxiliary support wheels can be provided. During the movement of the trolley, the support wheels contact the wall to separate the wall from the magnet, but this method can only Adapt to a flat wall surface. When the wall surface is non-straight, such as the curved surface of a pipe, the magnet on the fixi...

Problems solved by technology

[0002]At present, in the prior art, the way to mount the magnet on the wall climbing trolley includes setting the magnet on the bottom plate or setting the magnet on the fixed plate, the fixed plate It is installed under the bottom plate. Under some special working conditions, when the car is in the upward position, the adsorption force may be insufficient and the car may fall

[0003]In addition, one end of the fixed plate can be hinged on the wheel shaft, and the other end is free, and auxiliary supporting wheels are set, so that the trolley supports the wheels and the wall during the movement contact to separate the wall from the magnet, but this method can only be adapted to a flat wall. When the wall is non-straight, such as the curved surface of a pipe, the magnet on the fixing plate will inevitably contact the wall. When high, the magnet will inevitably be scratched

And the self-adaptive angle mechanism of this structure has no relevant limit measures. When the bottom is not placed on the working surface, the two parts of the hinge are easy to be adsorbed together, causing obstacles to use.
