Description

Technical Field

[0001] This application relates to the technical field, specifically to a brake-assisted driving device for a trackless rubber-wheeled vehicle. Background Technology

[0002] Trackless rubber-tired vehicles are commonly used for transportation operations in mine roadways. Since mine roadways are often characterized by long downhill slopes, these vehicles are prone to brake failure during prolonged descents, posing a significant threat to transportation safety. To address this issue, stop ropes are typically installed to halt stalled vehicles. However, existing stop ropes are usually exposed on the mine roadway surface for extended periods, and frequent vehicle traffic damages them, reducing their reliability, increasing maintenance costs, and ultimately failing to meet the safety requirements of mine transportation.

[0019] To make the content of this application easier to understand, the appendices in the embodiments of this application will be described below. Figure 1-6 The technical solutions in the embodiments of this application will be clearly and completely described. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to the appendix. Figure 2 In this context, the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. Furthermore, terms such as "first," "second," etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0020] like Figures 1-6 As shown, a trackless rubber-tired vehicle brake-assisted driving device includes a lane 1, a first receiving cavity 2, a second receiving cavity 3, a first rope winder 4, a second rope winder 5, a blocking rope 6, a fixed pulley block 7, a strip-shaped groove 8, and a drive assembly 9.

[0021] A first receiving cavity 2 and a second receiving cavity 3 are symmetrically provided on both sides of the tunnel 1. Both the first receiving cavity 2 and the second receiving cavity 3 are connected to the tunnel 1, providing installation space for the first rope winder 4, the second rope winder 5, and the drive assembly 9, while avoiding the components occupying the transportation space of the tunnel 1. The first receiving cavity 2 is equipped with the first rope winder 4, and the second receiving cavity 3 is equipped with the second rope winder 5. Both the first rope winder 4 and the second rope winder 5 are wound with a blocking rope 6. One end of the blocking rope 6 is fixed to the first rope winder 4, and the other end is fixed to the second rope winder 5. The blocking rope 6 spans the tunnel 1, and the first rope winder 4 and the second rope winder 5 work together to release and retract the blocking rope 6.

[0022] A strip-shaped groove 8 is provided on the ground of the tunnel 1 below the cross-shaped barrier rope 6. The cross-shaped barrier rope 6 can be placed in the strip-shaped groove 8. When not in operation, the barrier rope 6 is placed in the strip-shaped groove 8 to prevent passing vehicles from running over it and to reduce damage to the barrier rope 6. Fixed pulley groups 7 are provided on the side of the first receiving cavity 2 and the second receiving cavity 3 near the tunnel 1. The fixed pulley groups 7 are set corresponding to the strip-shaped groove 8. The barrier rope 6 passes through the fixed pulley groups 7. The fixed pulley groups 7 guide the movement direction of the barrier rope 6 to ensure that the position of the barrier rope 6 is stable during the raising and lowering process and can accurately enter the strip-shaped groove 8 or rise to the stopping height.

[0023] The first receiving cavity 2 is also equipped with a drive assembly 9, which is connected to the first rope winder 4 to provide power for the rotation of the first rope winder 4, thereby realizing the tightening and loosening of the blocking rope 6.

[0024] The first rope winder 4 includes a first rotating seat 401, a first rotating shaft 402, a first rotating drum 403, and a first hydraulic rotation damper 405. The first rotating seat 401 is fixedly installed in the first receiving cavity 2, providing stable support for the first rotating shaft 402. The first rotating shaft 402 is rotatably mounted on the first rotating seat 401, and the first hydraulic rotation damper 405 is also fixedly mounted on the first rotating seat 401. The first hydraulic rotation damper 405 is connected to the first rotating shaft 402. When the trackless rubber-wheeled vehicle hooks the barrier rope 6, it moves... When in motion, the first hydraulic rotary damper 405 generates damping force, which hinders the rotation of the first rotating shaft 402, thereby providing deceleration force for the trackless rubber-wheeled vehicle; a first rotating drum 403 is fixedly installed on the first rotating shaft 402, and one end of the barrier rope 6 is fixedly connected to the first rotating drum 403 and the barrier rope 6 is wound around the first rotating drum 403. The first rotating drum 403 is connected to the drive assembly 9 for transmission. The drive assembly 9 drives the first rotating drum 403 to rotate, thereby realizing the winding or release of the barrier rope 6 on the first rotating drum 403, and thus completing the winding and releasing of the barrier rope 6.

[0025] The second rope winder 5 includes a second rotating seat 501, a second rotating shaft 502, a second rotating drum 503, and a second hydraulic rotary damper 504. The second rotating seat 501 is fixedly installed in the second receiving cavity 3 to provide support for the second rotating shaft 502. The second rotating shaft 502 is rotatably mounted on the second rotating seat 501, and the second hydraulic rotary damper 504 is also fixedly mounted on the second rotating seat 501. The second hydraulic rotary damper 504 is connected to the second rotating shaft 502 and cooperates with the first hydraulic rotary damper 405 to enhance the deceleration effect on the trackless rubber-wheeled vehicle. The second rotating drum 503 is fixedly mounted on the second rotating shaft 502. The other end of the blocking rope 6 is fixedly connected to the second rotating drum 503, and the blocking rope 6 is wound around the second rotating drum 503. When the blocking rope 6 is wound up or down, the second rotating drum 503 rotates with the movement of the blocking rope 6. The second hydraulic rotary damper 504 dampens the rotation of the second rotating drum 503 through the second rotating shaft 502.

[0026] Drive assembly 9 includes a drive motor 901, a drive gear 902, an external gear disc 404, a sliding seat 903, a slider 904, a slide rail 905, and a telescopic electric cylinder 906. The drive gear 902 is fixedly mounted on the output shaft of the drive motor 901. The external gear disc 404 is fixedly mounted on the lower outer periphery of the first rotating drum 403. The drive gear 902 meshes with the external gear disc 404 for transmission. The drive motor 901 drives the first rotating drum 403 to rotate through gear meshing. The drive motor 901 is fixedly mounted on the sliding seat 903. The slider 904 is fixedly mounted on the bottom of the sliding seat 903 and slides on the slide rail 905. The slide rail 905 is fixedly mounted on the first rotating drum 403. Inside the cavity 2, the sliding seat 903 can move along the slide rail 905 to adjust the position of the drive motor 901. A telescopic electric cylinder 906 is fixedly installed on one side of the slide rail 905 inside the first cavity 2. A connecting plate 907 is fixedly provided at the extended end of the telescopic electric cylinder 906. The connecting plate 907 is fixedly connected to the sliding seat 903. The telescopic direction of the telescopic electric cylinder 906 is parallel to the length direction of the slide rail 905. The telescopic electric cylinder 906 drives the sliding seat 903 to slide along the slide rail 905 through the connecting plate 907, thereby controlling the engagement or disengagement of the drive gear 902 and the external gear plate 404 to avoid damage to the drive motor 901 during the blocking process of the blocking rope 6.

[0027] The fixed pulley block 7 includes a fixed base 701, a first bracket 702, a second bracket 703, a horizontal pulley 704, and a vertical pulley 705. The fixed base 701 is fixedly connected to the first rotating base 401 and the second rotating base 501 to ensure the stable installation of the fixed pulley block 7. The first bracket 702 and the second bracket 703 are fixedly mounted on the fixed base 701 facing the roadway 1. The horizontal pulley 704 is rotatably mounted on the first bracket 702, and the vertical pulley 705 is rotatably mounted on the second bracket 703. The barrier rope 6 passes through the horizontal pulley 704 and the vertical pulley 705 in sequence. Through the cooperation of the horizontal pulley 704 and the vertical pulley 705, the barrier rope 6 is guided to ensure the accurate movement path of the barrier rope 6.

[0028] The support frame 702 has two horizontal pulleys 704 arranged horizontally along the radial direction of the barrier rope 6. The two horizontal pulleys 704 limit the barrier rope 6 in the horizontal direction to prevent it from deviating. The horizontal pulleys 704 are set at a height higher than the upper end of the vertical pulley 705, and the upper end of the vertical pulley 705 is higher than the ground level of the tunnel 1. This ensures that the barrier rope 6 can be higher than the ground level of the tunnel 1 when tightened, making it easy for the trackless rubber-tired vehicle to hook onto it. The vertical pulley 705 is positioned between the two horizontal pulleys 704 and aligned with the strip-shaped pit 8. The barrier rope 6 passes through the position between the two horizontal pulleys 704 and over the upper side of the vertical pulley 705, ensuring that the barrier rope 6 can accurately enter the strip-shaped pit 8 or rise to the stopping height after being guided by the vertical pulley 705.

[0029] When the barrier rope 6 is slack, it is laid over the vertical pulley 705 and placed in the strip-shaped pit 8; when the barrier rope 6 is tightened, it is higher than the top of the vertical pulley 705 and the ground of the tunnel 1, thus meeting the position requirements under different working conditions.

[0030] The working process of this utility model is as follows:

[0031] Initially, the barrier rope 6 is in a relaxed state and placed in the strip-shaped groove 8, and the drive gear 902 of the drive assembly 9 meshes with the external gear disk 404.

[0032] When the trackless rubber-tired vehicle stalls, the control room controls the drive motor 901 of the drive assembly 9 to rotate. The drive motor 901 drives the drive gear 902 to rotate, which in turn drives the outer gear disk 404 to rotate. The outer gear disk 404 drives the first rotating drum 403 to rotate. The first rotating drum 403 rotates and tightens the barrier rope 6, making the barrier rope 6 higher than the height of the upper end of the vertical pulley 705 and the ground of the tunnel 1, so that the hook at the bottom of the trackless rubber-tired vehicle can hook the barrier rope 6. At the same time as the barrier rope 6 is tightened, the drive motor 901 stops, and the extended end of the telescopic electric cylinder 906 extends. Through the connecting plate 907, the sliding seat 903 slides along the slide rail 905. The sliding seat 903 drives the drive motor 901 to move, so that the drive gear 902 on the drive motor 901 separates from the outer gear disk 404, thus preventing the drive motor 901 from being stressed during the blocking process of the barrier rope 6. When the trackless rubber-tired vehicle passes the barrier rope 6, its bottom hook catches the barrier rope 6, and under the action of the first hydraulic rotary damper 405 and the second hydraulic rotary damper 504, the trackless rubber-tired vehicle gradually decelerates to a stop.

[0033] After the barrier is stopped, the staff removes the hook from the barrier rope 6. The control room controls the extension end of the telescopic cylinder 906 to retract. The telescopic cylinder 906 drives the sliding seat 903 to slide along the slide rail 905 through the connecting plate 907. The sliding seat 903 drives the drive motor 901 to move, so that the drive gear 902 on the drive motor 901 meshes with the outer gear plate 404. Then, the drive motor 901 of the drive assembly 9 is controlled to rotate. The drive motor 901 drives the drive gear 902 to rotate, and the drive gear 902 drives the outer gear plate 404 to rotate. The outer gear plate 404 drives the first rotating drum 403 to rotate. The first rotating drum 403 rotates to tighten the barrier rope 6, so that the barrier rope 6 returns to above the strip-shaped pit 8. Then, the drive motor 901 reverses, driving the first rotating drum 403 to reverse, so that the barrier rope 6 is relaxed. The relaxed barrier rope 6 is laid over the vertical pulley 705 and placed in the strip-shaped pit 8, returning to its initial state, ready for the next use.
