Description

Technical Field

[0001] The utility model relates to the technical field of coal mine mining, and particularly relates to a traveling device for coal mine mining. Background Art

[0002] "Coal mine mining" refers to the process of extracting coal resources from underground or surface mines. Coal is an important fossil fuel and is widely used in fields such as power generation, metallurgy, chemical industry, and household heating. Coal mine mining can be divided into two categories: underground mining and surface mining. Underground mining is carried out through mines and roadways below the surface, while surface mining directly extracts ore on the surface by stripping the overlying soil and rock covering the coal seam.

[0003] However, during the coal mine mining process, it is crucial for the operation of the conveyor. As a key device in coal mine mining, the stability of its performance and the reliability of the traveling device directly affect the mining efficiency and operation safety. Traditional coal mine traveling devices often have many deficiencies in complex and changeable mining environments, such as poor ground adaptability, easy wear, and high maintenance costs.

[0004] Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop a traveling device for coal mine mining. Content of the Utility Model

[0005] The purpose of the utility model is to provide a traveling device for coal mine mining to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A technical solution of a traveling device for coal mine mining includes a support beam. Wheel frames are installed on both sides of the bottom of the support beam. The wheel frames are connected to the support beam through connecting shafts. Multiple groups of wheels are arranged at the bottom of the wheel frames. The wheels are connected to the wheel frames through wheel shafts, and bronze bushes are sleeved between the wheel shafts and the wheels.

[0008] As a preferred technical solution, the edge of the wheel is arranged in a stepped shape for running on a predetermined track to prevent derailment.

[0009] As a preferred technical solution, a baffle is installed downward on the side of the wheel frame. The baffle is used for blocking to prevent derailment.

[0010] As a preferred technical solution, an oil cup is arranged on the wheel shaft. The oil cup is used for filling lubricating oil to ensure smooth operation between the wheel shaft, the wheel, and the bronze bush, reduce wear, and extend the service life.

[0011] As a preferred technical solution, a towing seat is installed on the wheel frame.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The present utility model is a walking device for coal mine mining. The wheel frame has a stable structure and is tightly connected to the support beam through a connecting shaft, ensuring the stability and load-bearing capacity of the entire walking device in a complex mining environment. The stepped design at the edge of the wheel not only increases the contact area with the track, improves the grip, but also significantly reduces the risk of derailment, ensuring the safety of the mining operation. In addition, the baffle design on the side of the wheel frame plays a dual-protection role, effectively preventing the wheel from accidentally derailing even under extreme working conditions, providing more reliable equipment support for coal mine mining.
