Description

Technical Field

[0001] The present technical solution relates to the technical field of mine car clutches, and in particular to a clutch mechanism for mine cars. Background Art

[0002] Now the development of mine cars is becoming more and more mature. As their loads are getting bigger and bigger, the power they need to adapt to is also getting bigger and bigger. Their horsepower has increased from the original maximum of 550 horsepower to 800 horsepower. This makes the original driven disc no longer applicable and cannot be adapted to high-horsepower mine cars. This is because low-horsepower mine cars generate less heat and use asbestos-free face sheets, which can effectively block heat from the large steel sheets, so the large steel sheets will basically not deform.

[0003] For high-horsepower mine cars, due to their large horsepower, in order to obtain sufficient transmission torque, the asbestos-free surface sheet is replaced with a copper-based sheet. The copper-based sheet has a large friction coefficient and good thermal conductivity. In addition, the sliding friction heat generated by the high-horsepower mine car is much greater than that of the low-horsepower mine car. The large steel sheet begins to expand after being subjected to huge heat, and will shrink after cooling. The difference in its thermal expansion coefficient and contraction coefficient will eventually cause the outline sheet to bend and shrink to one side. During the shrinkage process, the side where the outline sheet and the blocking sheet are riveted is blocked by the blocking sheet, and its shrinkage is much less than the other side without any obstruction, causing the large steel sheet to eventually deform into a "bowl shape", which in turn causes the clutch of the mine car to fail to work. Summary of the Invention

[0004] The purpose of this technical solution is to provide an outline piece mechanism for a mine car, which solves the problem that deformation of the outline piece cannot be avoided by setting only one support piece by respectively setting support piece one and support piece two on the front and rear sides of the outline piece assembly.

[0005] The purpose of this technical solution is achieved in this way:

[0006] A sheet metal mechanism for a mine car, comprising: an sheet metal assembly, which has a sheet metal body and a copper substrate group arranged on the sheet metal body; and support member 1 and support member 2, which are respectively affixed to the front and rear end surfaces of the sheet metal body and are used to clamp and support the sheet metal body; wherein the copper substrate group is arranged at the outer edges of the front and rear end surfaces of the sheet metal body, and the support member 1 and support member 2 are arranged at the center of the front and rear end surfaces of the sheet metal body.

[0007] Preferably, there is a gap between the outer edges of the support member 1 and the support member 2 and the inner edge of the copper substrate group.

[0008] Preferably, the gap is set to 1-4 mm.

[0009] Preferably, the support member 1 and the support member 2 are connected by a plurality of locking pins and fixed on the outline piece body.

[0010] Preferably, the outline sheet assembly further includes a mounting plate, which is arranged on the front end surface of the outline sheet body; the copper substrate group includes: copper substrate group 1, which is arranged on the mounting plate; and copper substrate group 2, which is arranged on the rear end surface of the outline sheet body.

[0011] Preferably, the outline piece body is provided with several mounting holes 2 for installing shock-absorbing springs; the support member 1 is provided with several mounting holes 3; the support member 2 is provided with several mounting holes 4; when the support member 1 and the support member 2 are installed on the outline piece body, the mounting holes 3 and the mounting holes 4 are both connected to the corresponding mounting holes 2.

[0012] Preferably, the copper substrate group is set on the mounting plate through a fixing part; the front end of the fixing part is placed in a countersunk hole opened on the surface of the copper substrate group, and the rear end passes through the copper substrate group and the mounting plate and is placed in a through hole opened on the surface of the outline sheet body.

[0013] Preferably, the copper substrate group 2 closes the through hole 1.

[0014] Preferably, the copper substrate group 2 is set on the outline piece body through the fixing part 2; the front end of the fixing part 2 is placed in the countersunk hole 2 opened on the surface of the copper substrate group 2, and the rear end passes through the copper substrate group 2 and the outline piece body and is placed in the through hole 2 opened on the mounting plate.

[0017] 1. This technical solution is designed by respectively setting support member 1 and support member 2 on the front and rear end surfaces of the outline sheet body. The two support members clamp and support the outline sheet body at the same time, which can prevent the outline sheet body from being deformed due to thermal expansion and contraction during use.

[0025] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 and Figure 2 As shown, a plate mechanism for a mine car is mounted on a disc hub 20 and connected to the flying disc of the engine. A spline is provided inside the center of the disc hub 20, and the disc hub 20 is connected to the transmission shaft of the clutch through the spline. The copper substrate group of the plate mechanism and the flying disc drive the plate body 5 of the plate mechanism to rotate through friction. When the clutch is working, the copper substrate group is separated from the flying disc. Therefore, when the mine car is working, the heat generated by the friction of the copper substrate group will cause the plate body 5 to heat up.

[0027] like Figure 1-3 As shown, the outline sheet mechanism includes an outline sheet assembly 1, support member 1 3 and support member 2 4. Support member 1 3 and support member 2 4 are respectively attached to the centers of the front and rear end surfaces of the outline sheet body 5 of the outline sheet assembly 1, and are arranged around the circumference of the disk hub 20. Support member 1 3 and support member 2 4 are fixed to each other and connected to the outline sheet body 5 by a number of locking pins 9. The clamping and support of the outline sheet body 5 by support member 1 3 and support member 2 4 can effectively prevent the inner ring of the outline sheet body 5 from deformation due to cooling after heating.

[0028] Furthermore, support member 1 3 and support member 2 4 are riveted to the outline piece body 5 through locking pins 9. Support member 1 3 and support member 2 4 have pin holes with corresponding positions. Each locking pin 9 can fix support member 1 3 and support member 2 4 at the same time.

[0029] Furthermore, the inner circle of the outline piece body 5 is provided with a plurality of mounting holes 2 11 for installing the shock-absorbing spring 10, and the support member 1 3 and the support member 2 4 are respectively provided with mounting holes 3 12 and mounting holes 4 13 for installing the shock-absorbing spring 10. Compared with the outline piece body 5 compressing the shock-absorbing spring 10 alone, the support member 1 3 and the support member 2 4 can cooperate with the outline piece body 5 to compress the shock-absorbing spring 10 at the same time, thereby increasing its overall physical strength and ensuring that the outline piece body 5 will not break. At the same time, the outer edges of the support member 1 3 and the support member 2 4 are arranged close to the inner edge of the copper substrate group, which increases the area of ​​the support member 1 3 and the support member 2 4 placed on the outline piece body 5, thereby increasing the clamping and supporting effect of the support member 1 3 and the support member 2 4 on the outline piece body 5.

[0030] like Figure 2 and Figure 3 As shown, the outline sheet assembly 1 includes an outline sheet body 5, a mounting plate 6, a copper substrate group 1 7 and a copper substrate group 2 8. The mounting plate 6 is arranged on the front end surface of the outline sheet body 5, the copper substrate group 1 7 is arranged on the outline sheet body 5 through the mounting plate 6, and the copper substrate group 2 8 is arranged on the rear end surface of the outline sheet body 5.

[0031] Specifically, the copper substrate group 1 7 includes several copper substrates 1, each of which is riveted to the mounting plate 6 through a fixing piece 14; the copper substrate group 2 8 includes several copper substrates 2, each of which is riveted to the outline sheet body 5 through a fixing piece 2 17.

[0032] Furthermore, there is a gap between the outer edges of support member 1 3 and support member 2 4 and the inner edge of the copper substrate group. The gap is used to prevent the two from being squeezed and deformed by each other due to thermal expansion and contraction. The gap is set in the range of 1-4 mm, which increases the area covered by support member 1 3 and support member 2 4 on the outline sheet body 5 to increase the stability of the outline sheet body 5 without interfering with the copper substrate group.

[0033] like Figure 4 and Figure 5 As shown, in order to increase the stability of the connection between the fixing part 14 and the fixing part 2 17, a plurality of countersunk holes 15 are opened on the surface of the copper substrate group 1 7, and the front end of the fixing part 14 is placed in the countersunk hole 15, and the rear end passes through the copper substrate group 1 7 and the mounting plate 6 and is placed in the through hole 16 opened on the surface of the outline sheet body 5. At this time, the copper substrate group 2 8 can close the through hole 16 to protect the fixing part 14; similarly, a plurality of countersunk holes 2 18 are opened on the surface of the copper substrate group 2 8, and the front end of the fixing part 2 17 is placed in the countersunk hole 2 18, and the rear end passes through the copper substrate group 2 8 and the outline sheet body 5 and is placed in the through hole 2 19 opened on the mounting plate 6. At this time, the copper substrate group 1 7 can close the through hole 2 19 to protect the fixing part 2 17.
