Description

Technical Field

[0001] This utility model relates to the field of coal mine transportation track technology, specifically to an auxiliary track for the tail wheel section of a coal mine transportation system. Background Technology

[0002] In coal mine transportation systems, the main underground auxiliary transportation mode is electric locomotive + railcar + monorail. Specifically, the main roadway of horizontal track uses battery-powered electric locomotives for transportation, the uphill (downhill) uses railcars or monorail, and the roadway uses monorail. Generally, the monorail is installed between the mine entrance and the deepest part of the mine. The tail wheel section of the monorail in the coal mine transportation system is located in the deepest part of the mine, which is also the section where the railcar stays for a relatively long time.

[0003] The published patent document CN208279199U discloses an auxiliary track for the tail wheel section of a coal mine transportation system. This published patent document sets up an auxiliary track at the tail wheel mechanism of the main track. The auxiliary track is connected to the main track. When the monorail crane travels to the tail wheel mechanism, it switches to the auxiliary track, which greatly reduces the labor of personnel to move materials and improves transportation efficiency. However, the railcar needs to brake and stop at the tail wheel section of the monorail in the coal mine transportation system, and the friction at the tail wheel section of the monorail is also relatively serious. However, the aforementioned published patent document cannot provide braking friction protection for the tail wheel section of the monorail, which means that the service life of the monorail in the coal mine transportation system cannot be guaranteed. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary track for the tail wheel section of a coal mine transportation system, which solves the problems mentioned in the background art.

[0005] This application provides an auxiliary track for the tail wheel section of a coal mine transportation system, including a single overhead rail and an auxiliary track mechanism. The bottom of the tail wheel section of the single overhead rail has two through holes. The auxiliary track mechanism includes two auxiliary rails, two threaded shafts, and two mounting components. The auxiliary rails are adapted to the through holes and pass through them. The top of the auxiliary rails has an M-shaped rail surface, and the auxiliary rails have transverse holes matching the threaded shafts. Two matching nuts are fitted at both ends of the threaded shafts. The two mounting components are welded to the bottom of the single overhead rail on both sides of the through holes, and each mounting component has two round holes matching the threaded shafts. An end protection mechanism is fixedly installed at the end of the tail wheel section of the single overhead rail.

[0006] By adopting the above technical solution, the auxiliary rail is passed through the through hole, and the threaded shaft is passed through the horizontal hole and the round hole. The nut is then turned and tightened to complete the installation of the auxiliary rail mechanism. The M-shaped rail surface can act as a brake on the railcar in the tail wheel section of the single overhead rail in the coal mine transportation system. It also facilitates the replacement of the auxiliary rail, thereby reducing the damage caused by the railcar brake to the single overhead rail in the coal mine transportation system.

[0007] Optionally, the end protection mechanism includes a mounting plate, two buffer components, and two buffer plates. Two connecting plates are fixedly connected to one side of the mounting plate. Four horizontal shafts are fixedly installed on the connecting plates. Connecting ears are integrally formed at the four corners of each buffer component. A compression spring is sleeved on each horizontal shaft, and the horizontal shaft passes through the connecting ear. The connecting ear is slidably connected to the horizontal shaft. The two ends of the compression spring are fixedly connected to the connecting ear and the connecting plate, respectively. A connecting rod is fixedly installed between the buffer component and the buffer plate. A rubber pad is attached to one side of the buffer plate.

[0008] By adopting the above technical solution, the rubber pad contacts the railcar roller, and the impact force of the railcar is transmitted to the buffer component through the buffer plate and connecting rod. The buffer component moves along the horizontal axis through the connecting lug and squeezes the compression spring to buffer the impact force of the railcar and prevent the railcar from hitting the end of the single-lift rail tail wheel section of the coal mine transportation system.

[0009] Optionally, matching gaskets are fitted at both ends of the threaded shaft.

[0010] By adopting the above technical solution, the friction between the nut and the mounting part is reduced.

[0011] Optionally, a baffle is fixedly installed at the end of the horizontal shaft.

[0012] By adopting the above technical solution, the connecting ear is prevented from slipping off the horizontal axis.

[0013] Optionally, reinforcing rods are symmetrically welded to the top and bottom of the connecting rod, and one end of the reinforcing rod is fixedly installed to the buffer plate.

[0014] By adopting the above technical solution, the stability of the installation between the connecting rod and the buffer plate is increased.

[0015] Optionally, the tail wheel section of the single-rail system in the coal mine transportation system has three threaded holes at its end, and three mounting bolts that match the threaded holes are threaded through and connected to the mounting plate, with one end of each mounting bolt inside the threaded hole.

[0016] By adopting the above technical solution, one end of the mounting bolt is screwed into the corresponding threaded hole, which facilitates the installation and disassembly of the end protection mechanism.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] 1. The technical solution of this application uses an auxiliary rail mechanism and through holes composed of an auxiliary rail, a threaded shaft, mounting parts, horizontal holes, round holes, and nuts to facilitate the installation and disassembly of the auxiliary rail. The M-shaped rail surface of the auxiliary rail can act as a brake on the railcar at the tail wheel section of the single-rail system in the coal mine transportation system, thereby reducing the damage caused by the railcar brake to the single-rail system in the coal mine transportation system and increasing the service life of the single-rail system in the coal mine transportation system.

[0019] 2. The technical solution of this application uses an end protection mechanism composed of an mounting plate, a buffer component, a buffer plate, a connecting plate, a horizontal shaft, a compression spring, a connecting rod, a rubber pad, a connecting lug, and a baffle plate to buffer the impact force of the railcar and prevent the railcar from hitting the end of the tail wheel section of the single-lift rail in the coal mine transportation system, thereby protecting the railcar and the single-lift rail of the coal mine transportation system.

Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Please see Figure 1-2 This utility model provides an auxiliary track for the tail wheel section of a coal mine transportation system, including a single overhead rail 1 and an auxiliary track mechanism 2. The bottom of the tail wheel section of the single overhead rail 1 has two through holes 4. The auxiliary track mechanism 2 includes two auxiliary rails 21, two threaded shafts 22, and two mounting parts 23. The auxiliary rails 21 are adapted to the through holes 4 and pass through the through holes 4. The top of the auxiliary rails 21 is provided with an M-shaped track surface 27, and the auxiliary rails 21 are provided with transverse holes 24 that match the threaded shafts 22. Both ends of the threaded shafts 22 are fitted with two matching nuts 26. The two mounting parts 23 are welded to the bottom of the single overhead rail 1 on both sides of the through holes 4, and each mounting part 23 is provided with two round holes 25 that match the threaded shafts 22. An end protection mechanism 3 is fixedly installed at the end of the tail wheel section of the single overhead rail 1.

[0028] In this technical solution, the auxiliary track mechanism 2 can be installed by passing the auxiliary track 21 through the through hole 4, then passing the threaded shaft 22 through the horizontal hole 24 and the round hole 25, and tightening it by rotating the nut 26. The m-shaped track surface 27 of the auxiliary track 21 can act as a brake on the railcar at the tail wheel section of the single overhead rail 1 in the coal mine transportation system, and it is convenient to replace the auxiliary track 21, thereby reducing the damage caused by the railcar brake to the single overhead rail 1 in the coal mine transportation system and increasing the service life of the single overhead rail 1 in the coal mine transportation system.

[0029] In some technical solutions, such as Figure 1 , Figure 3 and Figure 4 As shown, the end protection mechanism 3 includes a mounting plate 31, two buffer members 32 and two buffer plates 33. Two connecting plates 34 are fixedly connected to one side of the mounting plate 31. Four horizontal shafts 35 are fixedly installed on the connecting plates 34. Connecting ears 310 are integrally formed at the four corners of the buffer members 32. Compression springs 36 are sleeved on the horizontal shafts 35 and pass through the connecting ears 310. The connecting ears 310 and the horizontal shafts 35 are slidably connected. The two ends of the compression springs 36 are fixedly connected to the connecting ears 310 and the connecting plates 34 respectively. A connecting rod 37 is fixedly installed between the buffer members 32 and the buffer plates 33. A rubber pad 38 is pasted on one side of the buffer plate 33.

[0030] In use, the impact force of the railcar is transmitted to the buffer component 32 through the buffer plate 33 and the connecting rod 37 by the contact of the rubber pad 38 with the railcar roller. The buffer component 32 moves along the horizontal axis 35 through the connecting lug 310 and squeezes the compression spring 36 to buffer the impact force of the railcar and prevent the railcar from hitting the end of the tail wheel section of the single-suspension rail 1 of the coal mine transportation system, thus playing a protective role for the railcar and the single-suspension rail 1 of the coal mine transportation system.

[0031] In some technical solutions, such as Figure 2 As shown, matching gaskets 28 are fitted at both ends of the threaded shaft 22.

[0032] During use, the gasket 28 reduces friction between the nut 26 and the mounting part 23.

[0033] In some technical solutions, such as Figure 4 As shown, a baffle 311 is fixedly installed at the end of the horizontal axis 35.

[0034] When in use, the baffle 311 acts as a limit to prevent the connecting ear 310 from slipping off the horizontal axis 35.

[0035] In some technical solutions, such as Figure 3 As shown, reinforcing rods 39 are symmetrically welded to the top and bottom of the connecting rod 37, and one end of the reinforcing rod 39 is fixedly installed to the buffer plate 33.

[0036] In use, the reinforcement rod 39 increases the stability of the installation between the connecting rod 37 and the buffer plate 33.

[0037] In some technical solutions, such as Figure 3 As shown, three threaded holes 5 are provided at the end of the tail wheel section of the single overhead rail 1 in the coal mine transportation system. Three mounting bolts 6 that match the threaded holes 5 are threaded through and connected to the mounting plate 31. One end of the mounting bolt 6 is inside the threaded hole 5.

[0038] In use, the end protection mechanism 3 can be easily installed and disassembled by screwing one end of the mounting bolt 6 into the corresponding threaded hole 5.

[0039] Working principle: The auxiliary rail 21 is passed through the through hole 4, and the threaded shaft 22 is passed through the horizontal hole 24 and the round hole 25. The nut 26 is then turned and tightened to complete the installation of the auxiliary rail mechanism 2. The M-shaped rail surface 27 of the auxiliary rail 21 can act as a brake on the railcar at the tail wheel section of the single-lift rail 1 in the coal mine transportation system. It also facilitates the replacement of the auxiliary rail 21, thereby reducing the damage caused by the railcar brake to the single-lift rail 1 in the coal mine transportation system. When the railcar reaches the tail wheel section of the single-lift rail 1 in the coal mine transportation system, the rubber pad 38 will contact the railcar roller. The impact force of the railcar can be transmitted to the buffer component 32 through the buffer plate 33 and the connecting rod 37. The buffer component 32 moves along the horizontal axis 35 through the connecting ear 310 and squeezes the compression spring 36 to buffer the impact force of the railcar and prevent the railcar from hitting the end of the tail wheel section of the single-lift rail 1 in the coal mine transportation system.
