Description

Technical Field

[0001] This utility model relates to the field of railway safety technology, and in particular to an intelligent anti-runaway device. Background Technology

[0002] On railways, anti-slip shoes are primarily used to brake vehicles and prevent them from moving after braking. To ensure the safety and reliability of anti-slipping operations while improving efficiency and standardization, the use of anti-slip shoes requires strict adherence to operating procedures and maintaining the equipment in good working order. Currently, anti-slipping operations mainly rely on manual placement of the shoes, which suffers from low efficiency and high labor intensity. Especially in severe weather conditions such as rain, snow, and ice, the friction between the shoes and the track is easily affected, posing safety hazards for manual operation. Furthermore, with the expansion of railway lines and the gradual decrease in the number of personnel, the contradiction between anti-slipping equipment and the needs of modern operation and maintenance is becoming increasingly prominent.

[0003] The patent application number "CN 202321404054.5" discloses "a railway locomotive maintenance anti-runaway device". Its main purpose is to clamp the rail by setting movable lifting columns on both sides of the anti-runaway device to prevent the anti-runaway device from falling or tipping over; however, it cannot realize the automatic placement (when in use) and removal (after use) of the anti-runaway device. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent anti-slip device that can automatically place and remove the anti-slip device, greatly reducing the workload of operators and improving work efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The intelligent anti-slip device includes a metal shoe and a flipping device for installing the metal shoe on the rail or removing the metal shoe from the rail. The flipping device includes a first fixing block fixed on the rail. The first fixing block is rotatably connected to a rotating plate via a pin. The rotating plate is connected to a first telescopic rod that pushes it to rotate. The metal shoe is set on the rotating plate.

[0010] Preferably, the flipping device further includes a second mounting plate that can abut against the lower surface of the first slide rail. The second mounting plate has a fixing groove, and a positioning member is provided in the fixing groove. The positioning member is connected to the support member through an elastic member. The first fixing block has a positioning plate that can abut against the support member to compress the elastic member.

[0011] Preferably, the end of the first telescopic rod is provided with a movable joint, and the movable joint is connected to the rotating plate through a guide rod.

[0012] Preferably, the movable joint is provided with an arched portion, and a third mounting plate is provided between the second slider and the first slide rail, with a pulley at the bottom of the third mounting plate that cooperates with the arched portion.

[0034] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0035] The present invention will now be further described with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figure 4 , Figure 6 and Figure 7 As shown, the intelligent anti-slip device includes a metal shoe 2 and a flipping device for installing the metal shoe 2 on the rail 1 or removing the metal shoe 2 from the rail 1. The flipping device includes a first fixing block 6 fixed on the rail 1. The first fixing block 6 is rotatably connected to a rotating plate 7 via a pin 62. The rotating plate 7 is connected to a first telescopic rod 5 that pushes it to rotate. The metal shoe 2 is set on the rotating plate 7.

[0038] like Figure 2 As shown, the iron shoe 2 has a sole arc surface 20 that contacts the rail 1 and an upper tread arc surface 21 that contacts the wheel. The rear side of the iron shoe 2 is also provided with an anti-tipping inclined side 22, and baffles 23 are provided on both sides of the lower part of the iron shoe 2.

[0039] In terms of materials, the shoe 2 is made of lighter aluminum alloy and is integrally molded to ensure overall strength. To ensure a better fit between the sole and the rail 1, the sole surface is machined into a corresponding arc surface 20 according to the specific rail type, achieving a surface contact of over 70% between the finished shoe and the rail. We also considered the burrs that may form on the rail due to wear and deformation during actual use. Therefore, the design did not simply use the standard dimensions of new rails; instead, the sole width was appropriately adjusted, and the dimensions of the arc surface that contacts the burrs were specifically improved to better suit practical applications. The upper tread of the shoe is also designed with an arc surface (i.e., upper tread arc surface 21) according to the corresponding wheel radius for different types of vehicles. This ensures that the upper tread engages synchronously with the wheel when it presses down on the shoe, minimizing the risk of the shoe tipping over. The triangular rib-like beveled edges 22 at the top of the upper tread and the bottom of the sole serve the same purpose. Furthermore, we have covered both the sole arc surface 20 and the upper tread arc surface 21 with a high-abrasion-resistant material to achieve the effect of converting the kinetic energy of the vehicle's slippage into sliding friction with the rails as it slides forward with the wheel friction, thereby decelerating and braking the vehicle. This also prevents the wheel from crossing the shoe. In this embodiment, the high-abrasion-resistant material is carbon fiber.

[0040] like Figure 8 — Figure 11 As shown, the flipping device also includes a second slide rail 10 fixedly connected to the baffle 23 of the slipper 2. A matching second slider 101 is provided on the second slide rail 10. In this embodiment, the second slider 101 remains stationary, while the second slide rail 10 moves within the second slider 101. When a train approaches, the vehicle pushes the slipper 2, causing the second slide rail 10 to move. In the field of anti-runaway, to ensure braking and anti-runaway effects, multiple intelligent anti-runaway devices as described in this embodiment are arranged on the rail 1 to ensure that the train can be stopped.

[0041] The second slider 101 is connected to the first slide rail 9. The first slide rail 9 is provided with a matching first slider 91. In this embodiment, the first slider 91 is stationary, while the first slide rail 9 can drive the second slider 101, the second slide rail 10, and the baffle 23 (iron shoe 2) to move up and down. The first slider 91 is connected to the rotating plate 7 through the first mounting plate 8.

[0042] The flipping device also includes a second mounting plate 11 that can abut against the lower surface of the first slide rail 9. The second mounting plate 11 has a fixing groove 111, which is an elongated groove (allowing for a certain amount of movement for the positioning member 112). The positioning member 112 is disposed within the fixing groove and is connected to the support member 113 via an elastic element (not shown in the figure). The first fixing block 6 has a positioning plate 61 that can abut against the support member 113 to compress the elastic element. In this embodiment, the elastic element is a spring. The end of the support member 113 that abuts against the positioning plate 61 is thinner, and the end connected to the positioning member 112 is thicker, forming a hollow sleeve structure. The elastic element is installed inside the hollow sleeve. When the flipping device is in a horizontal state (unused state, at which time the iron shoe 2 is not installed on the rail 1), the elastic element is not under force. At this time, the elastic element pulls the positioning element 112, so that the second mounting plate 11 abuts against the first slide rail 9, preventing the first slide rail 9 from sliding. When the flipping device is activated, after the rotating plate 7 flips upward, the support 113 abuts against the positioning plate 61, so that the elastic element is squeezed. At this time, the elastic element pushes the positioning element 112 to move outward, and the second mounting plate 11 no longer abuts against the first slide rail 9, and the first slide rail 9 can slide downward.

[0043] The end of the first telescopic rod 5 is provided with a movable joint 51, which is connected to the rotating plate 7 via a guide rod 52.

[0044] An arched portion 53 is provided on the movable joint 51. A third mounting plate 12 is also provided between the second slider 101 and the first slide rail 9. A pulley support seat 121 is provided at the bottom of the third mounting plate 12. A pulley 122 that cooperates with the arched portion 53 is provided at the bottom of the pulley support seat 121.

[0045] like Figure 5 As shown, to better secure the first fixing block 6, a second fixing block 4 is also provided. The second fixing block 4 and the first fixing block 6 are symmetrically fixed on both sides of the rail 1, and the two can be connected by bolts to more reliably fix them to the rail 1. Figure 3 and Figure 4As shown, the second fixing block 4 can be further fixed by the fixing rod 41 to reduce the possibility of it shaking. The bottom of the second fixing block 4 and the first fixing block 6 are provided with a clearance slot 42. When the first telescopic rod 5 retracts and the flipping device drives the iron shoe 2 to rotate to a horizontal state, the clearance slot 42 can make way for the pulley 122 to retract smoothly because the pulley 122 retracts.

[0046] In this embodiment, when not in use, the shoe 2 is located on one side of the rail 1, and the first telescopic rod 5 is in a retracted state. When in use, the shoe 2 needs to be placed on the rail 1. This placement process is a two-stage action: 1. The first telescopic rod 5 extends, and through the guide rod 52, it drives the rotating plate 7 to rotate around the first fixed block 6, flipping the entire flipping device and the shoe 2 connected to it to the top of the rail 1; 2. At this time, the support member 113 abuts against the positioning plate 61, causing the elastic member to be squeezed. The elastic member pushes the positioning member 112 and the second mounting plate 11 to move outward. At this time, the second mounting plate 11 no longer abuts against the first slide rail 9, and the first slide rail 9 can move down along the first slider 91 (driving the third mounting plate 12, pulley support seat 121, pulley 122, and the second slider 101, the second slide rail 10, and the shoe 2 connected to the first slide rail 9 to move down), until the shoe 2 contacts the rail 1. In use, multiple anti-slip devices are arranged sequentially on rail 1. When a train brakes, it pushes the slipper 2 to move continuously on rail 1 until it comes to a stop. When the slipper 2 moves on rail 1, it mainly drives the second slide rail 10 to move within the second slider 101.

[0047] When the iron shoe 2 needs to be flipped to the side of the rail 1 after use, the process is also a two-stage action: 1. The first telescopic rod 5 retracts, and the arched part 53 first contacts the pulley 122. As the arched part 53 moves, the pulley 122 will gradually rise (the pulley support 121, the third mounting plate 12, the first slide rail 9, the second slider 101, the second slide rail 10, and the iron shoe 2 rise synchronously); 2. The first telescopic rod 5 continues to retract, and the guide rod 52 drives the rotating plate 7 to rotate in the opposite direction around the first fixed block 6, rotating the entire flipping device and the iron shoe 2 connected to it to the side of the rail 1.

[0048] like Figure 12 and Figure 13As shown, locking blocks 13 are provided at both ends of the third mounting plate 12. The locking blocks 13 are L-shaped and there are two of them. The gourd-shaped bolt 131 passes through the locking block 13 and enters the second slide rail 10, connecting the two as one. The gourd-shaped bolt 131 has a nut 132, and the middle of its threaded portion is machined into a thinner connecting part 135. The two ends of the connecting part 135 are the first thread 133 and the second thread 134, respectively. In use, the second thread 134 is screwed into the second slide rail 10, and the first thread 133 is located inside the locking block 13. This achieves the locking of the second slide rail 10 and the shoe 2, preventing the shoe from sliding due to manual operation or other accidents. When the train approaches and needs to brake, the kinetic energy of the train will break the gourd-shaped bolt 131 at the thinner connecting part 135, allowing the second slide rail 10 and the shoe 2 to move along the second slider 101.

[0049] like Figure 1 and Figure 3 As shown, the device also includes a second telescopic rod 3, the end of which is provided with a movable head 31. To reliably protect the tilting device and components such as the first telescopic rod 5 and the second telescopic rod 3, a first outer casing 300 and a second outer casing 400 are also provided on both sides of the rail 1. In this embodiment, the fixed ends and fixed rod 41 of the first telescopic rod 5 and the second telescopic rod 3 can be enclosed within the first outer casing 300 for protection, and the movable ends of the first telescopic rod 5 and the second telescopic rod 3, as well as the tilting device, can be enclosed within the second outer casing 400.

[0050] The second outer casing 400 has a cover plate. When the second telescopic rod 3 extends, the movable head 31 can open the cover plate. At this time, the flipping device can flip upward to install the iron shoe 2 on the rail 1. After the iron shoe is used, the flipping device removes the iron shoe, the second telescopic rod 3 retracts, and the movable head 31 can close the cover plate.

[0051] In this embodiment, both the first telescopic rod 5 and the second telescopic rod 3 are electric actuators. The parameters of the second telescopic rod 3 are: voltage 24V, rod length 200mm, speed 160mm / s, thrust 100N, and dimensions 32mm x 32mm. The parameters of the first telescopic rod 5 are: voltage 24V, rod length 150mm, speed 160mm / s, thrust 100N, and dimensions 32mm x 32mm. Both electric actuators are connected to an external control circuit to control their telescopic movement.
