Description

Technical Field

[0001] The utility model relates to the technical field of coal mining machines, in particular to a visual device for traveling wheels of a traveling part of a coal mining machine. Background Art

[0002] With the continuous advancement of mining technology, the automation and efficiency of coal mining have been continuously improved, and the requirements for the reliability and safety of coal mining machines have also been continuously improved. The travel part is an important part of several large parts of the coal mining machine. The travel wheel is engaged with the pin row (or rack) to realize the travel of the coal mining machine on the scraper conveyor. Its reliability and stability are of great significance to the overall performance of the coal mining machine.

[0003] The driving wheels and traveling wheels of the traveling part of the coal mining machine are directly exposed in the open space formed by the traveling box shell. They work in an unsealed box and are in direct contact with the air. They are polluted by coal dust, particles and stones all year round. Stones and other debris are easy to enter, and the erosion of various corrosive liquids seriously affects the life of the gears. Under the condition of low speed and heavy load, the tooth surface of the traveling box is subjected to great stress and is easy to wear, which affects the service life of the gears to a certain extent. Moreover, the traveling box gears are vulnerable parts, which are large in size, expensive, and have a long production cycle, which seriously affects the start-up rate of the coal mining machine.

[0004] In addition to design and process methods, timely maintenance is also an important means to improve the reliability and stability of the coal mining machine travel box. One of the important means of maintaining the travel wheels of the current thin coal seam coal mining machine travel box is to observe the wear of the travel wheels by removing the observation window cover above the travel box shell, to know the wear of the travel wheels in advance, and to replace the travel wheels in advance, thereby improving the reliability and stability of the travel box. The currently used travel box observation window cover is made of metal, and the wear of the travel wheels cannot be observed in real time. Every time the wear of the travel wheels is observed, the observation window cover above the travel box shell must be removed. However, the operating space of the thin coal seam coal mining machine working face itself is narrow, and the disassembly work is somewhat difficult, which greatly reduces the work efficiency of the entire maintenance work of the thin coal seam coal mining machine. Utility Model Content

[0005] The purpose of the utility model is to propose a visual device for the walking wheels of the walking part of a coal mining machine. The wear condition of the walking wheels can be known in advance without removing the observation window cover above the walking box shell, which greatly improves the maintenance efficiency of the walking box, and further greatly improves the work efficiency of the entire maintenance work of the thin coal seam coal mining machine.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] The utility model discloses a visual device for the traveling wheel of the traveling part of a coal mining machine, comprising tempered glass and a tempered glass fixed protective plate, an observation window is arranged above a traveling box shell, the tempered glass fixed protective plate is installed above the traveling box shell, the tempered glass fixed protective plate is located directly above the observation window, an observation port is arranged on the tempered glass fixed protective plate, the tempered glass is attached to the traveling box shell, the tempered glass is located on the observation window, and the tempered glass is located below the observation port.

[0008] Furthermore, the tempered glass is a flat plate, and the observation port includes groove one and groove two, groove one is located below groove two, the length of groove two is smaller than the length of groove one, the width of groove two is smaller than the width of groove one, the length of groove one is greater than the length of the observation window, and the width of groove two is greater than the width of the observation window.

[0009] Furthermore, the size of the second groove is the same as the size of the observation window.

[0010] Furthermore, the tempered glass is located in one groove.

[0011] Furthermore, rubber pads are provided between the four corners of the upper end of the tempered glass and the tempered glass fixing protective plate.

[0012] Furthermore, the tempered glass fixed protection plate is connected to the travel box housing through four bolts and washers.

[0013] The beneficial effects of the utility model are:

[0014] When the thin coal seam coal mining machine is walking left or right on the scraper to cut coal normally, or when the maintenance team is repairing the coal mining machine, the underground workers can observe the wear of the walking wheel in real time through the tempered glass of the utility model, understand the situation conveniently and quickly, and make corresponding judgments according to the actual situation. This greatly improves the maintenance efficiency of the walking box, and then greatly improves the work efficiency of the entire maintenance work of the thin coal seam coal mining machine. Ultimately, the goal of improving the reliability and stability of the thin coal seam coal mining machine is achieved, and the customer's requirements for high production and high efficiency of the coal mining machine are met.
