Technical Field

The utility model relates to the technical field of coal mining machines, in particular to a walking wheel capable of being welded in a split mode.

Background

The walking wheel of the coal mining machine is the most key part of the coal mining machine and is a main part for providing walking of the coal mining machine, the walking wheel is meshed with a pin row of a scraper conveyor to drive the coal mining machine to walk back and forth, the walking wheel is also stressed maximally and impacted maximally by load, no matter the hardness of a core part and the hardness of a surface must meet design standards, an integral forging piece must be made of the best material, the whole walking wheel is high in manufacturing cost, the coal mining machine works in a mine cavity, the ground is rich in coal slag and broken stone, and once the coal slag and the broken stone are clamped between the teeth of the walking wheel, the teeth of the wheel are easily damaged.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects in the prior art and provides a walking wheel capable of being welded in a split mode.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a but split welded walking wheel, includes the wheel body, a plurality of teeth of a cogwheel of fixedly connected with on the wheel body, each the cavity has all been seted up on the teeth of a cogwheel, the cavity inner wall is equipped with the closing mechanism, the equal fixedly connected with of wheel body lateral wall meshes the board, it is connected with the round pin rail through the connecting piece to mesh the board.

Preferably, the sealing mechanism comprises a sealing rotating shaft rotatably connected with the inner wall of the cavity, an elastic plate is fixedly connected to the sealing rotating shaft, and torsion springs are sleeved on the outer side walls of the sealing rotating shaft and located on two sides of the elastic plate.

Preferably, the connecting piece comprises a meshing nut fixedly connected with the pin rail, the surface of the meshing nut is provided with a plurality of thread grooves matched with the meshing nut, and the meshing nut is meshed with the inner wall of each thread groove.

Preferably, the wheel body is made of 0# steel, and the meshing plate is made of stainless bearing steel.

Compared with the prior art, the utility model has the beneficial effects that:

1. through the material with the wheel body adoption 20# steel, the material that the meshing board adopted the stainless bearing steel for when not influencing walking wheel bulk strength and performance, greatly reduced the manufacturing cost of walking wheel.

2. Through setting up closing mechanism for when walking the wheel and rolling cinder and rubble, produce through the elastic plate and block cinder and rubble, avoid rubble and cinder card to walking between each teeth of a cogwheel, cause the damage to the wheel tooth.
