Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for transport vehicles, specifically an anti-runaway device for bidirectional transport vehicles. Background Technology

[0002] Two-way transportation refers to the movement of goods in the logistics supply chain, not just in one direction, but by making full use of transportation routes and resources to achieve bidirectional flow of goods. Compared with traditional one-way transportation, two-way transportation is more efficient and economical, better meeting market demands and improving the logistics environment.

[0003] Bi-directional transport vehicles generally need to be kept stable on the ground during loading to prevent the vehicle from rolling away after parking. Currently, the most commonly used method is to place a tire guard on both sides of the tire to prevent the vehicle from rolling away. However, this type of tire guard is very unstable. If the tire guard is touched during loading and its position is shifted, it can easily cause the bi-directional transport vehicle to roll away, resulting in unnecessary danger. Utility Model Content

[0004] In view of the above situation and to overcome the existing defects, this utility model provides an anti-runaway device for bidirectional transport vehicles.

[0005] The present invention provides the following technical solution: The present invention proposes an anti-runaway device for a bidirectional transport vehicle, comprising: a main frame and a transmission device;

[0006] A first baffle is fixed at one end of the pair of main frames, and a second baffle is provided at the other end of the main frame away from the first baffle. A first slide groove, a first slide rail and an arc-shaped slide rail are each carved on the end of the pair of main frames near the second baffle. The first slide rail and the arc-shaped slide rail are connected to each other. A pair of first rotating shafts and a pair of second rotating shafts are fixed on the second baffle. A plurality of anti-slip nails are fixed at the bottom of the pair of main frames.

[0007] The transmission device is mounted on the main frame. The transmission device includes a pair of moving rods. A first pushing block is fixed to one end of each moving rod near the second baffle. A fixed block is fixed to the end of each moving rod away from the first pushing block. A second pushing block is fixed to the first pushing block near the first rotating shaft. A sliding rod is fixed to the fixed block. A pair of second sliding grooves are chiseled on the main frame. A crossbar is slidably arranged on the pair of second sliding grooves. One end of the crossbar is located inside the main frame and is slidably connected to the sliding rod. An L-shaped push rod is fixed to the crossbar.

[0008] Furthermore, a second slide rail is fixed inside the main frame near the first slide groove. The second slide rail is used to limit the sliding of the slider within it and prevent the slider from rotating. A circular rail is fixed at one end of the second slide rail near the second baffle. The circular rail is used to limit the slider from rotating within it, thereby causing the second baffle to rotate about the axis of the circular rail.

[0009] Furthermore, the first rotating shaft slides within the first groove, and a limiting slider is fixed at one end of the first rotating shaft that passes through the first groove and is located within the circular rail. On one hand, by restricting the limiting slider to rotate within the circular rail, the second baffle rotates around the first rotating shaft. On the other hand, the limiting slider slides within the second rail, and when it slides within the second rail, the second rail restricts the limiting slider from rotating, thereby preventing the second baffle from rotating. A push rod is fixed at the end of the limiting slider away from the first rotating shaft, and the push rod is pushed by the second push block, thereby driving the second baffle to move.

[0010] Furthermore, the arc axis of the arc-shaped slide rail and the axis of the circular rail are the same axis, so that when the second baffle rotates around the circular rail, the second rotating shaft slides along the trajectory of the arc-shaped slide rail into the first slide rail.

[0011] Furthermore, the second rotating shaft slides within the first slide rail and the arc-shaped slide rail. The second rotating shaft passes through the first slide rail and the arc-shaped slide rail. At one end of the second rotating shaft located within the main frame, a first pulley is installed. The first pulley is pushed by the first pushing block, thereby causing the second baffle to rotate and move.

[0012] Furthermore, the first pushing block is provided with an arc-shaped groove and an arc-shaped slope. When the first pushing block pushes the first pulley through the arc-shaped slope, it drives the second rotating shaft to slide in the arc-shaped slide rail. When the first pulley moves into the arc-shaped groove, the first pushing block drives the second rotating shaft to move in the first slide rail, and at the same time drives the limiting slider to slide in the second slide rail, thereby driving the second baffle to move towards the first baffle.

[0013] Furthermore, a connecting rod is fixed to one end of the pair of sliding rods located outside the main frame. By pushing the connecting rod, the pair of sliding rods are moved. A pair of first springs are installed between the crossbar and the inner wall of the main frame. When the crossbar is not subjected to external force, the first springs push the crossbar to move towards the fixed block.

[0014] Furthermore, each end of the crossbar is provided with a plug, and each pair of sliding rods is provided with a slot. The plug is placed in the slot, so that when the crossbar moves, it drives the sliding rod to move. The sliding rod drives the moving rod to move through the fixed block.

[0015] Furthermore, a second spring is installed between each pair of the insert rods and the inner wall of the crossbar. When the insert rods are not subjected to external force, the elastic force provided by the second spring pushes the insert rods into the slots. A control rod is fixed on each pair of insert rods. One end of the control rod is located outside the crossbar. The control rod drives the insert rods to move. By squeezing the pair of control rods inward, the insert rods are moved out of the slots.

[0016] Furthermore, a second pulley is installed at the end of the L-shaped push rod away from the crossbar. The second pulley is used to reduce friction when the tire pushes the L-shaped push rod.

[0017] The present invention, employing the above-described structure, proposes an anti-runaway device for bidirectional transport vehicles, which can secure bidirectional transport vehicles in a parked state and prevent the transport vehicles from running away and causing unnecessary dangers.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0032] like Figures 1 to 7 As shown, this embodiment provides an anti-runaway device for a bidirectional transport vehicle, including: a main frame 1 and a transmission device 2.

[0033] like Figures 1 to 7As shown, a first baffle 101 is fixed to one end of a pair of main frames 1, and a second baffle 102 is provided at the other end of the main frame 1 away from the first baffle 101. The first baffle 101 and the second baffle 102 are used to block the tires on both sides to fix the tires in both directions and prevent the transport vehicle from running. A first groove 105, a first slide rail 106, and an arc-shaped slide rail 108 are each carved on the end of the pair of main frames 1 near the second baffle 102. The first slide rail 106 and the arc-shaped slide rail 108 are connected to each other. The first groove 105 is used for the sliding of the first rotating shaft 103, and the first slide rail 106 and the arc-shaped slide rail 108 are used for the sliding of the second rotating shaft 104. A pair of first rotating shafts 103 and a pair of second rotating shafts 104 are fixed on the second baffle 102. The first rotating shafts 103 are used for the second baffle 102 to rotate as the axis, and the second rotating shafts 104 are used to drive the second baffle 102 to rotate about the first rotating shaft 103 as the axis. Multiple anti-slip nails 113 are fixed to the bottom of a pair of main frames 1. The anti-slip nails 113 serve to prevent slipping and stabilize the frame.

[0034] like Figures 1 to 7 As shown, a second slide rail 109 is fixed inside the main frame 1 near the first slide groove 105. The second slide rail 109 is used to limit the sliding of the slider 110 within it and to prevent the slider 110 from rotating. A circular rail 107 is fixed to one end of the second slide rail 109 near the second baffle 102. The circular rail 107 is used to limit the rotation of the slider 110 within it, thereby causing the second baffle 102 to rotate about the axis of the circular rail 107. The first rotating shaft 103 slides within the first groove 105. One end of the first rotating shaft 103, which passes through the first groove 105 and is located within the circular rail 107, is fixed with a limiting slider 110. On one hand, by restricting the limiting slider 110 to rotate within the circular rail 107, the second baffle 102 rotates around the first rotating shaft 103. On the other hand, by allowing the limiting slider 110 to slide within the second rail 109, and when sliding within the second rail 109, the second rail 109 restricts the limiting slider 110 from rotating, thereby preventing the second baffle 102 from rotating.

[0035] like Figures 1 to 7As shown, a push rod 112 is fixed to the end of the limiting slider 110 away from the first rotating shaft 103. The push rod 112 is pushed by the second push block 203, thereby driving the second baffle 102 to move. The arc axis of the arc-shaped slide rail 108 and the axis of the circular rail 107 are the same axis, so that when the second baffle 102 rotates about the circular rail 107, the second rotating shaft 104 slides along the trajectory of the arc-shaped slide rail 108 into the first slide rail 106. The second rotating shaft 104 slides in the first slide rail 106 and the arc-shaped slide rail 108. The end of the second rotating shaft 104 that passes through the first slide rail 106 and the arc-shaped slide rail 108 and is located in the main frame 1 is equipped with a first pulley 111. The first push block 202 pushes the first pulley 111, thereby causing the second baffle 102 to rotate and move.

[0036] like Figures 3 to 10 As shown, the transmission device 2 is mounted on the main frame 1. The transmission device 2 includes a pair of moving rods 201. A first pushing block 202 is fixed to one end of each moving rod 201 near the second baffle 102. The first pushing block 202 is used to push the second rotating shaft 104. A fixing block 206 is fixed to the end of each moving rod 201 away from the first pushing block 202. The fixing block 206 is used to move the moving rod 201 and the first pushing block 202. A second pushing block 203 is fixed to the first pushing block 202 near the first rotating shaft 103. The second pushing block 203 drives the second baffle 102 to move by pushing the push rod 112. A sliding rod 207 is fixed to the fixing block 206. The sliding rod 207 is used to move the fixing block 206. A pair of second sliding grooves 210 are carved into a pair of main frames 1. A crossbar 209 is slidably mounted on the pair of second sliding grooves 210. One end of the crossbar 209 located inside the main frame 1 is slidably connected to a slide bar 207. The crossbar 209 is used to drive the slide bar 207 to move. An L-shaped push rod 211 is fixed on the crossbar 209. The L-shaped push rod 211 is used to push the crossbar 209 to move.

[0037] like Figures 3 to 10 As shown, the first pushing block 202 is provided with an arc-shaped groove 204 and an arc-shaped slope 205. When the first pushing block 202 pushes the first pulley 111 through the arc-shaped slope 205, it drives the second rotating shaft 104 to slide within the arc-shaped slide rail 108. When the first pulley 111 moves into the arc-shaped groove 204, the first pushing block 202 drives the second rotating shaft 104 to move within the first slide rail 106, and simultaneously drives the limiting slider 110 to slide within the second slide rail 109, thereby driving the second baffle 102 to move towards the first baffle 101. A pair of sliding rods 207 are fixed to a connecting rod 213 at one end outside the main frame 1. By pushing the connecting rod 213, the pair of sliding rods 207 are moved. A pair of first springs 208 are installed between the crossbar 209 and the inner wall of the main frame 1. When the crossbar 209 is not subjected to external force, the first springs 208 push the crossbar 209 to move towards the fixed block 206.

[0038] like Figures 8 to 10 As shown, each end of the crossbar 209 is fitted with a rod 215. A pair of sliding rods 207 each have a slot 214. The rods 215 are positioned within the slots 214. The movement of the crossbar 209 causes the sliding rods 207 to move, and the sliding rods 207 move via the fixing block 206. A second spring 217 is installed between each pair of rods 215 and the inner wall of the crossbar 209. When no external force is applied, the elastic force provided by the second spring 217 pushes the rods 215 into the slots 214. A control rod 216 is fixed to each pair of rods 215. One end of the control rod 216 is located outside the crossbar 209. The control rod 216 moves the rods 215. By squeezing the control rods 216 inwards, the rods 215 are removed from the slots 214. A second pulley 212 is installed at the end of the L-shaped push rod 211 away from the crossbar 209. The second pulley 212 is used to reduce friction when the tire pushes the L-shaped push rod 211.

[0039] In practical use, when goods need to be loaded onto a bidirectional transport vehicle, first place this device behind the tires of the bidirectional transport vehicle, and then slowly move the transport vehicle from the side of the second baffle 102 towards the direction of the first baffle 101. When the tires of the bidirectional transport vehicle move, they first run over the second baffle 102, and then come to the space between the second baffle 102 and the first baffle 101. After that, the bidirectional transport vehicle continues to move towards the direction of the first baffle 101. When the tires contact the second pulley 212, the tires push the L-shaped push rod 211 towards the direction of the connecting rod 213 through the second pulley 212. The L-shaped push rod 211 drives a pair of sliding rods 207 to move through the crossbar 209. The sliding rods 207 drive the moving rod 201 to move through the fixed block 206. The moving rod 201 drives the first push block 202 to move.

[0040] When the first pushing block 202 contacts the first pulley 111 during its movement, the limiting slider 110 is stuck in the circular rail 107 and can only rotate within the circular rail 107. Therefore, the first pushing block 202 cannot push the second baffle 102 to move. The first pushing block 202 pushes the second rotating shaft 104 to slide along the arc slope 205 through the first pulley 111, causing the second rotating shaft 104 to slide within the arc slide rail 108. The second rotating shaft 104 drives the second baffle 102 to rotate around the first rotating shaft 103 as its axis. When the first pulley 111 moves into the arc groove 204, the second rotating shaft 103... 04 also moves into the first slide rail 106, and at the same time, the limiting slider 110 rotates to an angle that matches the trajectory of the second slide rail 109. At this time, the moving rod 201 continues to drive the first pushing block 202 to move. The first pushing block 202 drives the second baffle 102 to move towards the first baffle 101 through the second rotating shaft 104. During the movement, the second rotating shaft 104 slides in the first slide rail 106, and the limiting slider 110 slides in the second slide rail 109. After moving to the appropriate position, the bidirectional transport vehicle stops. At this time, the tires are restricted between the first baffle 101 and the second baffle 102, thereby preventing the bidirectional transport vehicle from running.

[0041] When the vehicle needs to be moved after loading, first, a pair of control levers 216 are squeezed inward. The control levers 216 drive the insert rod 215 out of the slot 214, and then push the connecting rod 213 towards the second baffle 102. The connecting rod 213 pushes the moving rod 201 towards the second baffle 102 via the slide rod 207 and the fixing block 206. The moving rod 201 drives the second pushing block 203 to move. When the second pushing block 203 moves to the push rod 112, it pushes the push rod 112, thereby driving the second baffle 102 to move away from the tire. The second baffle 102 drives the second rotating shaft 104 from... After the first slide rail 106 moves to the arc slide rail 108, the second baffle 102 stops moving. At this time, the second rotating shaft 104 slides down along the trajectory of the arc slide rail 108, so that the second baffle 102 rotates to its original position. Then, the bidirectional transport vehicle drives out between a pair of main frames 1. During the process of the bidirectional transport vehicle driving out, the tires no longer push against the second pulley 212. At this time, the elastic force of the first spring 208 pushes the crossbar 209 to move towards the fixed block 206. When it moves to the slot 214, the elastic force of the second spring 217 pushes the insert rod 215 into the slot 214 again, so that the crossbar 209 and the slide rod 207 are in a locked state.
