Abstract
Description
Technical Field
[0001] This application relates to the field of tunneling machines, and more particularly to an anti-slip track pad. Background Technology
[0002] The track plates of the tunneling machine's traveling section are used to support the weight of the tunneling machine. When the tunneling machine is moving, they bear the weight of the tunneling machine and provide friction for the tunneling machine to move forward. The reliability and failure rate of this device directly affect the traveling function and tunneling efficiency of the tunneling machine.
[0003] The existing track plates for underground tunneling machines in coal mines are mainly designed as integral plates with anti-slip ribs added to the ground contact side. Currently, the anti-slip ribs in China are mainly herringbone, figure-eight, wave, and grid shapes. Although the above designs have increased the anti-slip effect of the track plates to a certain extent in practical applications, the anti-slip effect is not ideal when the tunneling machine is tunneling on a steep slope. Utility Model Content
[0004] To address the aforementioned problems, this application provides an anti-slip track plate.
[0005] The anti-slip track plate provided in this application adopts the following technical solution:
[0006] An anti-slip track plate includes a track plate body. The track plate body is provided with an anti-slip structure for improving the stability of the track plate body. The anti-slip structure includes a first transverse rib plate disposed on the upper surface of the track plate body. A second transverse rib plate is fixedly connected to one side of the upper surface of the track plate body located at the first transverse rib plate. The height of the first transverse rib plate is higher than that of the second transverse rib plate. Both ends of the second transverse rib plate are fixedly connected to protrusions. The height of the protrusions is higher than that of the second transverse rib plate and lower than that of the first transverse rib plate. Two vertical ribs are fixedly connected between the protrusions and the first transverse rib plate. The heights of the two ends of the vertical ribs are respectively matched with the heights of the first transverse rib plate and the second transverse rib plate.
[0007] By adopting the above technical solution, during use, the second horizontal stiffener plate and the protrusions on both sides form a stepped shape to prevent the tunneling machine from sliding sideways. At the same time, the vertical stiffeners form two sets of horseshoe-shaped anti-slip ribs with the first horizontal stiffener plate and the protrusions, which increases the friction between the track plate body and the ground when it comes into contact with the ground during movement. This prevents the tunneling machine from sliding down when it is tunneling on a steep slope, and minimizes the problem of unsatisfactory anti-slip effect when the tunneling machine is tunneling on a steep slope.
[0008] Preferably, one end of the track plate body is provided with multiple connecting grooves, and the other end of the track plate body is fixedly connected with multiple connecting blocks that are adapted to the connecting grooves. The sidewalls of the connecting blocks and the sidewalls of the connecting grooves are provided with matching pin holes, and the upper surface of the track plate body near the two ends of the connecting grooves is provided with stop pin holes for fixing the pin shaft.
[0009] By adopting the above technical solution, the connecting blocks are placed into the connecting grooves respectively, and then the pins are passed through the pin holes to connect the multiple track plate bodies to form a track. Then, the external bolts are passed through the pin holes to be threadedly connected to the pins to fix the pins and prevent them from moving, thus installing and fixing the multiple track plate bodies.
[0010] Preferably, a shock-absorbing block is mounted on the upper surface of the track plate body, and a plurality of screws are provided on one side of the shock-absorbing block. The screws pass through the shock-absorbing block and are threadedly connected to the track plate body.
[0011] By adopting the above technical solution, when the tunneling machine is transporting or tunneling in near-horizontal roadways, the vibration of the machine can be reduced and the damage to the floor plate can be minimized by fixing the shock-absorbing blocks to the main body of the track plate with screws.
[0012] Preferably, the shock absorber has multiple receiving holes on the side wall away from the track plate body for concealing the screws.
[0013] By adopting the above technical solution, when the screw is passed through the shock absorber and threaded to the track plate body, the nut end of the screw enters the receiving hole, which can hide the screw and prevent the screw from extending to the outside of the shock absorber.
[0014] Preferably, the track plate body has two first positioning blocks on both sides of its lower surface, and two second positioning blocks are provided between the two first positioning blocks on its lower surface.
[0015] By adopting the above technical solution, the first positioning block and the second positioning block can limit the track plate body when the tunneling machine is moving, and prevent the track plate body from falling off.
[0016] Preferably, each of the receiving holes is provided with a washer to improve the stability of the screw.
[0017] By adopting the above technical solution, the stability of the screw connection can be improved and the screw can be prevented from loosening by using washers.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] 1. This application utilizes the coordinated arrangement of the first horizontal stiffener, the second horizontal stiffener, and the vertical stiffener to prevent the tunneling machine from sliding sideways during use. The second horizontal stiffener, together with the protrusions on both sides, forms a stepped shape. Simultaneously, the vertical stiffeners create two sets of horseshoe-shaped anti-slip ribs between the first horizontal stiffener and the protrusions, increasing the friction between the track plate and the ground during movement. This prevents the tunneling machine from sliding down steep slopes, minimizing the problem of inadequate anti-slip performance during steep slope tunneling.
[0020] 2. When transporting tunneling machines or excavating near-horizontal tunnels, fixing the shock-absorbing blocks to the track plate body with screws can reduce machine vibration and minimize damage to the floor plate. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0027] This application discloses an anti-slip track plate.
[0028] Reference Figure 1 , Figure 2 and Figure 3 An anti-slip track plate includes a track plate body 1, and an anti-slip structure for improving the stability of the track plate body 1 is provided on the track plate body 1. The anti-slip structure includes a first transverse rib 2, a second transverse rib 3, a protrusion 4 and a vertical rib 5.
[0029] The first horizontal stiffener 2 is fixedly connected to one side of the upper surface of the track plate body 1. The second horizontal stiffener 3 is fixedly connected to the upper surface of the track plate body 1 located on one side of the first horizontal stiffener 2. The height of the first horizontal stiffener 2 is higher than that of the second horizontal stiffener 3. Two protrusions 4 are provided and fixedly connected to both ends of the second horizontal stiffener 3 respectively. The height of the protrusions 4 is higher than that of the second horizontal stiffener 3 and lower than that of the first horizontal stiffener 2. Two sets of vertical stiffeners 5 are provided, with two in each set. Each set of vertical stiffeners 5 is fixedly connected between the protrusions 4 and the first horizontal stiffener 2 respectively. The heights of the two ends of the vertical stiffener 5 are matched with the heights of the first horizontal stiffener 2 and the second horizontal stiffener 3 respectively.
[0030] Reference Figure 1 and Figure 3 The track plate body 1 has multiple connecting grooves 6 at one end and multiple connecting blocks 7 that are adapted to the connecting grooves 6 are fixedly connected to the other end of the track plate body 1. The side walls of the connecting blocks 7 and the side walls of the connecting grooves 6 are provided with matching pin holes 8. The upper surface of the track plate body 1 has stop pin holes 9 for fixing the pin shaft at both ends near the connecting grooves 6. By placing the connecting blocks 7 into the connecting grooves 6 respectively, and then passing the pin shaft through the pin holes 8, the multiple track plate bodies 1 are connected to each other to form a track. Then, through the stop pin holes 9, the external bolts are passed through the stop pin holes 9 and threadedly connected to the pin shaft to fix the pin shaft and prevent the pin shaft from moving, thus installing and fixing the multiple track plate bodies 1.
[0031] Reference Figure 1 and Figure 2 The upper surface of the track plate body 1 is equipped with a shock-absorbing block 10. The shock-absorbing block 10 is made of shock-absorbing materials such as polyurethane and TPE. Multiple screws 11 are provided on one side of the shock-absorbing block 10. The screws 11 pass through the shock-absorbing block 10 and are threadedly connected to the track plate body 1. When the tunneling machine is transporting or tunneling in near-horizontal roadways, the shock-absorbing block 10 is fixed to the track plate body 1 by the screws 11, which can reduce the vibration of the machine and reduce the damage to the bottom plate.
[0032] Reference Figure 2 The shock absorber 10 has multiple receiving holes 12 on the side wall away from the track plate body 1 for hiding screws 11. When the screw 11 is passed through the shock absorber 10 and threaded to the track plate body 1, the nut end of the screw 11 enters the receiving hole 12, which can hide the screw 11 and prevent the screw 11 from extending to the outside of the shock absorber 10.
[0033] Reference Figure 4 The track plate body 1 has two first positioning blocks 13 on both sides of its lower surface. The track plate body 1 has two second positioning blocks 14 located between the two first positioning blocks 13 on its lower surface. The first positioning blocks 13 and the second positioning blocks 14 can limit the track plate body 1 when the tunneling machine is moving, preventing the track plate body 1 from falling off.
[0034] Reference Figure 2 Each receiving hole 12 is provided with a washer 15 to improve the stability of the screw 11. The washer 15 can improve the stability of the screw 11 connection and prevent the screw 11 from loosening.
[0035] The implementation principle of an anti-slip track plate according to an embodiment of this application is as follows: In use, connecting blocks 7 are placed into connecting grooves 6 respectively, and then multiple track plate bodies 1 are connected to each other by passing pins through pin holes 8 to form a track. Then, external bolts are passed through pin holes 9 to threadedly connect with pins to fix the pins and prevent them from moving. This fixes the multiple track plate bodies 1. Then, the second transverse stiffener 3 and the protrusions 4 on both sides form a stepped shape to prevent the tunneling machine from sliding sideways. At the same time, the vertical stiffener 5 makes the first transverse stiffener 2 and the protrusions 4 form a stepped shape. Two sets of horseshoe-shaped anti-slip ribs increase the friction between the track plate body 1 and the ground when it is in contact with the ground during movement, preventing the tunneling machine from sliding down when it is tunneling on a steep slope. At the same time, when the tunneling machine is transporting or tunneling in near-horizontal tunnels, the screw 11 passes through the shock absorber 10 and the nut end of the screw 11 enters the receiving hole 12 to hide the screw 11. The screw 11 is threadedly connected to the track plate body 1, which can reduce the vibration of the machine and reduce the damage to the bottom plate, thus avoiding the problem of unsatisfactory anti-slip effect when the tunneling machine is tunneling on a steep slope.
[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
