Description

Technical Field

[0001] This utility model relates to the technical field of tunnel construction equipment, specifically a track-moving vehicle stopper for horizontal tunnels. Background Technology

[0002] During tunnel construction, in order to prevent mine cars, flatbed cars, forklifts, etc. from automatically sliding when they stop, and to ensure the safety of construction personnel and equipment, various types of car-stopping wood and temporary car-stopping devices are now widely used.

[0003] According to the publication number (CN208325251U), a moving car stop for a horizontal track is disclosed, which includes two right-angled triangular wheel stops. The inclined surface of the wheel stops is an inwardly concave arc shape, and the bottom of the wheel stops is provided with a U-shaped groove. Both the inclined surface and the U-shaped groove of the wheel stops are provided with a brake band. The two wheel stops are connected by a connecting rod, so that the U-shaped grooves of the two wheel stops can respectively cooperate with the horizontal track.

[0004] The implementation of this technical solution has at least the following drawbacks: Although this utility model can prevent vehicles from sliding abnormally, relying solely on the U-shaped groove to confine the wheel stop seat to the track results in poor stability and makes it inconvenient to buffer impact forces and reduce wheel stop seat displacement. Therefore, we propose a moving vehicle stop for level track. Utility Model Content

[0005] The purpose of this utility model is to provide a moving wheel stop device for flat track, which solves the problems mentioned in the background art, such as poor stability when the wheel stop is limited to the track by only relying on the U-shaped groove, and the inconvenience in buffering the impact force and reducing the displacement of the wheel stop.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a moving vehicle stop for a horizontal track, comprising a track body, a wheel stop seat at the upper end of the track body, a fixing frame fixedly installed at the front end of the wheel stop seat, a fixing plate on one side of the wheel stop seat, a straight rod fixedly installed in the middle of the fixing plate, a fixing rod fixedly installed at the lower front end of the fixing plate, a first wedge block welded to the lower end of the fixing rod, a second wedge block provided on the inner side of the fixing frame, the lower end of the first wedge block fitting against the upper end of the second wedge block, a slider fixedly installed at the front end of the second wedge block, and a sliding groove opened on the inner side of the fixing frame.

[0007] By adopting the above technical solution, the fixed plate can drive the fixed rod to move, while the first wedge block on the fixed rod pushes the second wedge block, causing the second wedge block to move downwards and stretching the second spring. The second wedge block abuts against the lower track groove of the track body, thereby limiting the position of the wheel stop seat. This solves the problem of poor stability when the wheel stop seat is limited to the track by the U-shaped groove alone. Furthermore, the first and second springs work together, stretching simultaneously during the contact between the wheel and the wheel stop seat, thus buffering the impact force of the wheel and reducing the possibility of wheel stop seat displacement.

[0008] Optionally, a first spring is fitted on one side of the straight rod, and the other end of the first spring is fixedly connected to the wheel stop seat.

[0009] By adopting the above technical solution and by setting the first spring, the fixed plate can be driven to reset.

[0010] Optionally, a rubber pad is bonded to the lower end of the wheel chock seat, and the size of the rubber pad is adapted to the size of the wheel chock seat.

[0011] By adopting the above technical solution and setting rubber pads, the friction between the wheel stop seat and the upper part of the track body is increased.

[0012] Optionally, one end of the straight rod is disposed through the middle of the wheel stop seat.

[0013] By adopting the above technical solution and setting the straight rod, it can be ensured that the straight rod contacts the wheel first, thereby driving the fixed plate to move.

[0014] Optionally, the size of the slider is adapted to the size of the groove, and the slider and the groove are slidably connected.

[0015] By adopting the above technical solution, the stability of the movement of the second wedge block can be guaranteed through the cooperation of the slider and the groove.

[0016] Optionally, a second spring is fixedly installed in the inner cavity of the slide, and the other end of the second spring is fixedly connected to the slider.

[0017] By adopting the above technical solution and by setting the second spring, the second wedge block can be driven to reset.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] The technical solution of this application, through the setting of a track body, wheel stop seat, rubber pad, straight rod, fixed rod, first wedge block, slider and second spring, can make the fixed plate drive the fixed rod to move, while the first wedge block on the fixed rod pushes the second wedge block, causing the second wedge block to move downward, and stretching the second spring. The second wedge block abuts against the lower track groove of the track body, thereby limiting the position of the wheel stop seat. This solves the problem of poor stability when the wheel stop seat is limited to the track by the U-shaped groove alone. In addition, the first spring and the second spring work together. When the wheel contacts the wheel stop seat, the first spring and the second spring are stretched at the same time, thereby buffering the impact force of the wheel and reducing the displacement of the wheel stop seat.

[0026] Please see Figure 1-4This utility model provides a technical solution: a moving vehicle stopper for a level track, comprising a track body 1, a wheel stop seat 11 at the upper end of the track body 1, a fixing frame 13 fixedly installed at the front end of the wheel stop seat 11, a fixing plate 2 on one side of the wheel stop seat 11, a straight rod 21 fixedly installed in the middle of the fixing plate 2, a fixing rod 23 fixedly installed at the front side of the lower end of the fixing plate 2, a first wedge block 3 welded to the lower end of the fixing rod 23, a second wedge block 31 provided on the inner side of the fixing frame 13, the lower end of the first wedge block 3 fitting against the upper end of the second wedge block 31, a slider 33 fixedly installed at the front end of the second wedge block 31, and the fixing frame... A groove 32 is provided on the inner side of 13. One end of the straight rod 21 is inserted through the middle of the wheel stop seat 11. The straight rod 21 is designed to ensure that it contacts the wheel first, thereby driving the fixed plate 2 to move. The size of the slider 33 is matched with the size of the groove 32, and the slider 33 is slidably connected to the groove 32. The cooperation between the slider 33 and the groove 32 ensures the stability of the movement of the second wedge block 31. A second spring 4 is fixedly installed in the inner cavity of the groove 32. The other end of the second spring 4 is fixedly connected to the slider 33. The second spring 4 can drive the second wedge block 31 to reset.

[0027] A first spring 22 is sleeved on one side of the straight rod 21, and the other end of the first spring 22 is fixedly connected to the wheel stop seat 11. The first spring 22 can drive the fixed plate 2 to reset.

[0028] A rubber pad 12 is bonded to the lower end of the wheel stop 11, and the size of the rubber pad 12 is adapted to the size of the wheel stop 11. The setting of the rubber pad 12 increases the friction between the wheel stop 11 and the upper part of the track body 1.

[0029] When the vehicle is stopped, the wheel stop 11 is first engaged above the track body 1. The vehicle's wheel will first contact the straight rod 21. The straight rod 21 drives the fixing plate 2 to move to the left, while stretching the first spring 22. The fixing plate 2 drives the fixing rod 23 to move accordingly. At the same time, the first wedge block 3 on the fixing rod 23 pushes the second wedge block 31, causing the second wedge block 31 to move downward, while stretching the second spring 4. The second wedge block 31 abuts against the lower track groove of the track body 1, thereby limiting the position of the wheel stop 11. This solves the problem of poor stability when the wheel stop 11 is limited to the track by the U-shaped groove alone. At the same time, through the cooperation of the first spring 22 and the second spring 4, the first spring 22 and the second spring 4 are stretched at the same time during the contact between the wheel and the wheel stop 11, thereby buffering the impact force of the wheel and reducing the displacement of the wheel stop 11.
