Description

Technical Field

[0001] The utility model belongs to the technical field of road hazard avoidance devices or equipment, and particularly relates to a linkage device for a blocking cable and an anti-rolling baffle applied to a runaway truck ramp. Background Art

[0002] During the construction of a tunnel inclined shaft, relevant vehicles face the problem of long-distance downhill. In order to control the vehicle speed, the driver has to apply brakes for a long time, which may cause the vehicle brakes to fail and the vehicle to get out of control. In order to stop the out-of-control vehicle, a runaway truck ramp is often set up. However, how to set up a runaway truck ramp so that it can stop the out-of-control vehicle safely and efficiently is a problem that needs to be solved at present.

[0003] Common runaway truck ramps at present include arranging buffer objects such as tires at the end of the runaway truck ramp, or arranging devices such as anti-collision bars to absorb momentum after the vehicle hits, so as to reduce the damage; or building the runaway truck ramp as an upward slope to convert the kinetic energy of the out-of-control vehicle into gravitational potential energy to make the vehicle stop finally. The defects of this device are as follows:

[0004] (1) Although using tires or other buffer objects can reduce part of the impact force, it cannot completely avoid the damage caused by the collision. Moreover, in a tunnel, the stress situation is complex, and the remaining impact force may still affect the stability of the surrounding rock, leading to more serious safety problems;

[0005] (2) Setting the runaway truck ramp to have an upward slope can use the gravity of the vehicle itself to achieve the deceleration effect. However, after the vehicle stops, due to the effect of gravity, there is a risk of rolling. If not prevented, it will cause secondary accidents. Summary of the Invention

[0006] The technical problem to be solved by the utility model is to overcome the above-mentioned deficiencies of the prior art, and provide a linkage device for a blocking cable and an anti-rolling baffle applied to a runaway truck ramp, which adopts a runaway truck ramp with a slope, and at the same time sets an anti-rolling device, and combines with a blocking cable. While achieving double deceleration, it can also effectively avoid the occurrence of rolling.

[0007] The technical solution adopted to solve the above technical problem is: a linkage device for a blocking cable and an anti-rolling baffle applied to a runaway truck ramp, which is characterized by comprising a blocking and anti-rolling unit and a vehicle cooperation unit;

[0008] The described anti-rolling unit for blocking is as follows: At least one set of groove structures is provided in the road trend direction of the main body of the escape lane. The baffle main body is arranged in the groove structure through a baffle shaft installed on the side wall of the groove structure. The baffle main body is rotationally connected to the groove structure. One end of the baffle main body is provided with a blocking cable through a blocking cable fixing plate. Signal transmission holes and limiting holes are provided on the end face of the baffle main body. The signal transmission holes are through holes. Infrared signal generators, infrared signal receivers, and limiting grooves are symmetrically arranged in the groove structure with respect to the baffle main body. A first magnetic part and a limiting rod are arranged in the limiting groove;

[0009] The described vehicle matching unit is as follows: A hook mounting bracket is provided on the vehicle chassis. A hook that can rotate relative to it is provided on the hook mounting bracket through a hook shaft. A second magnetic part is provided at one end of the hook mounting bracket, and the second magnetic part is used in cooperation with the hook.

[0010] A spring is arranged between the first magnetic part and the limiting rod of the present utility model.

[0011] One end of the hook mounting bracket of the present utility model is processed with a shaft groove, a hook rotation groove, and the other end is provided with a hook sliding groove.

[0012] The baffle main body of the present utility model is of a cylindrical structure, and a conical protrusion is provided at one circumferential end of the cylindrical structure. The blocking cable is arranged on the conical protrusion.

[0013] The second magnetic part of the present utility model is electrically connected to the vehicle central control system.

[0014] The anti-rolling unit for blocking of the present utility model further includes a controller, and the first magnetic part and the infrared receiver are electrically connected to the controller.

[0015] The setting of the signal transmission holes and the limiting holes of the present utility model should ensure that when the signal emitted by the infrared signal generator passes through the signal transmission holes, the limiting holes are just aligned with the limiting grooves and the limiting rod can extend into the limiting holes. Since the present utility model adopts the linkage of the anti-rolling unit for blocking and the vehicle matching unit, it has the following advantages:

[0016] 1. Using a blocking cable to brake the vehicle, compared with traditional tires or other buffers, it avoids the collision of the vehicle;

[0017] 2. When the baffle main body is not raised, it can act as a speed bump. When the blocking cable is pulled and the baffle main body is rising, by controlling the friction between the baffle shaft and the baffle main body, the rotation speed of the baffle main body is further controlled to further brake the vehicle;

[0018] 3. After the baffle body is fully raised, the signal emitted by the infrared signal generator passes through the signal transmission hole and is received by the infrared signal receiver. The infrared receiver transmits the received signal to the controller. The controller controls the second magnetic part to stop working. The limit rod pops out under the action of the spring force and is stuck in the limit hole to limit the rotation of the baffle body. At this time, the conical section of the baffle body is higher than the main slope of the safe lane, which can prevent the car from slipping. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited to these embodiments.

[0025] Example 1

[0026] exist Figures 1 to 4 The utility model relates to a blocking cable and anti-slip baffle linkage device applied to a dangerous lane, comprising a blocking and anti-slip unit and a vehicle matching unit;

[0027] Specifically, the blocking and anti-rolling unit is composed of a runaway lane main body 1, a groove structure 2, a blocking cable 3, a blocking cable fixing plate 4, a baffle main body 5, a signal transmission hole 6, a limiting hole 7, a baffle shaft 8, a limiting groove 9, a first magnetic member 10, an infrared signal generator 11, an infrared signal receiver 12, a spring 13, and a limiting rod 14. At least one group of groove structures 2 is arranged in the road trend direction of the runaway lane main body 1. The baffle main body 5 is arranged in the groove structure 2 through a baffle shaft 8 installed on the side wall of the groove structure 2. The baffle main body 5 is rotatably connected to the groove structure 2. The baffle main body 5 in this embodiment is of a cylindrical structure, and a conical protrusion is arranged at one circumferential end of the cylindrical structure. The blocking cable 3 is arranged on the conical protrusion through the blocking cable fixing plate 4. A signal transmission hole 6 and a limiting hole 7 are arranged on the end face of the baffle main body 5. The signal transmission hole 6 is a through hole. An infrared signal generator 11, an infrared signal receiver 12, and a limiting groove 9 are symmetrically arranged in the groove structure 2 with respect to the baffle main body 3. A first magnetic member 10 and a limiting rod 14 are arranged in the limiting groove 9. In order to ensure the smooth ejection of the limiting rod 14, a spring 13 is arranged between the first magnetic member 10 and the limiting rod 14. Further, the signal transmission hole 6 and the limiting hole 7 are arranged such that when the signal emitted by the infrared signal generator 11 passes through the signal transmission hole 6, the limiting hole 7 is just aligned with the limiting groove 9 and the limiting rod 14 can extend into the limiting hole 7. The blocking and anti-rolling unit further includes a controller. The first magnetic member 10 and the infrared receiver 12 are electrically connected to the controller. The controller receives the signal transmitted by the infrared receiver 12 and controls the start and stop of the first magnetic member 10.

[0028] The described vehicle matching unit is composed of a hook mounting bracket 15, a hook 16, a hook shaft 17, and a second magnetic member 18. A hook mounting bracket 15 is arranged on the vehicle chassis. One end of the hook mounting bracket 15 is processed with a shaft groove 19 and a hook rotation groove 21, and the other end is provided with a hook sliding groove 20. The hook 16 is arranged on the hook mounting bracket 15 through the hook shaft 17 and can rotate relative to the hook mounting bracket 15. A second magnetic member 18 is arranged at one end of the hook mounting bracket 15. The second magnetic member 18 is used in cooperation with the hook 16, and the second magnetic member 18 is electrically connected to the vehicle central control system.

[0029] The working principle of the present utility model is as follows:

[0030] When the out-of-control vehicle enters the main body 1 of the escape lane, first, the vehicle will rush to the high point along the bottom of the main body 1 of the escape lane. During this process, a large amount of impact energy will be absorbed, thereby reducing the speed of the vehicle. At the same time, the vehicle driver operates the central control system to stop the second magnetic member 18 from working. After the second magnetic member 18 stops, the hook 16 moves downward along the hook sliding groove 20 under its own gravity. As the vehicle advances, the hook 16 successfully engages with the arresting cable 3 to restrict the vehicle. By setting multiple sets of arresting and anti-rolling units, it can be ensured that in the case where the first arresting and anti-rolling unit fails to engage with the cable successfully, subsequent cable engagement can still continue. Under the action of the forward driving force of the vehicle, the arresting cable 3 pulls the baffle main body 5 to rotate clockwise. When it rotates to a certain angle, the signal emitted by the infrared signal generator 11 passes through the signal transmission hole 6 and is received by the infrared signal receiver 12. The infrared receiver 12 transmits the received signal to the controller, and the controller controls the second magnetic member 18 to stop working. The limiting rod 14 pops out under the elastic force of the spring 13 and is inserted into the limiting hole 7 to restrict the rotation of the baffle main body 5. At this time, the conical section of the baffle main body 5 protrudes higher than the slope of the main body 1 of the escape lane, playing a role in preventing the vehicle from rolling back. After the fault is handled, the controller controls the second magnetic member 18 to work, compresses the spring 13 to retract the limiting rod 14 into the limiting groove 9, and operates the baffle main body 5 to reset.
