Description

Technical Field

[0001] The invention belongs to the technical field of transport tools, in particular to a horizontal blocking door leaf transfer vehicle. Background Art

[0002] The horizontal blocking door transfer vehicle is a mechanical equipment specially used for handling and transferring horizontal blocking doors. Through its specific design and structure, it can move flexibly in various working environments to ensure the safe, fast and efficient transportation of blocking doors.

[0003] In the prior art, when using a transfer vehicle, a comprehensive inspection of the transfer vehicle is required to ensure that the transfer vehicle is in good working condition and the transfer route is planned. Secondly, the horizontal blocking door is lifted by a steel cable, and then the transfer vehicle is pushed to move along the established route. When reaching the designated position, the transfer vehicle needs to be stopped steadily and the blocking door removed to complete the transfer work.

[0004] There are still some problems in the actual application of the above scheme. During the transportation process, when the transfer vehicle suddenly brakes and the rectangular blocking door is heavy, the blocking door will swing forward due to inertia. This swing will change the position of its center of gravity, making it unstable. The unstable center of gravity will cause the overall imbalance of the transfer vehicle, thereby affecting the vehicle's handling and stability. In extreme cases, this will cause the vehicle to overturn or lose control, causing serious safety accidents. At the same time, due to the unstable center of gravity, the rectangular blocking door will fall during the transportation process due to bumps, turns or acceleration, which will not only damage the rectangular blocking door itself, but also cause harm to surrounding equipment and personnel. Secondly, the added centering fixing mechanism will be misaligned during use, which will cause the operator to spend extra time and energy to correct the misalignment of the centering fixing mechanism, which will affect the continuity and efficiency of the transportation.

[0005] To this end, the present invention provides a horizontal blocking door leaf transfer vehicle. Summary of the invention

[0008] The centering fixing mechanism includes a support plate fixedly arranged on the side wall of the inner cavity of the support frame, and two groups of limit clamping plates are slidably arranged on the side of the support plate. The rectangular blocking door can be fixed and limited by the relative sliding of the two groups of limit clamping plates.

[0013] Preferably, the outer ring surface of the rotating gear is meshed with a second reciprocating rack, and the second reciprocating rack is fixedly connected to a second moving block at one end away from the rotating gear. The two groups of guide blocks are respectively adapted to the shapes of the slide grooves opened at the bottom of the first reciprocating rack and the second moving block.

[0014] Preferably, a second rectangular groove is provided at the lower portion of the second moving block, and two groups of the second rectangular grooves are provided, and the two groups of the second rectangular grooves are respectively provided at the lower portion of the second moving block and the upper portion of the first moving block.

[0015] Preferably, a first motor is fixedly provided on an upper portion of the second movable block away from the second rectangular groove, an output shaft of the first motor is fixedly connected to a rotating shaft, and an outer annular surface of the rotating shaft is fixedly connected to a limited clamping plate.

[0016] Preferably, an anti-deviation calibration mechanism for preventing misalignment is provided on the side of the centering fixing mechanism, the anti-deviation calibration mechanism includes a second motor, and a guide groove is provided in the middle of the side of the limit clamping plate.

[0017] Preferably, a first sliding block is slidably connected in the guide groove, a bidirectional screw is arranged in the middle of the first sliding block, the first sliding block is threadedly connected to the outer ring surface of the bidirectional screw, one end of the bidirectional screw is fixed to the output shaft of the second motor, the end of the bidirectional screw away from the first sliding block is threadedly connected to the second sliding block, and the second sliding block is slidably connected in the guide groove.

[0018] The beneficial effects of the present invention are as follows:

When the guide block moves, it will drive the rotating gear meshing with it to rotate, and drive the second reciprocating rack symmetrical with the first reciprocating rack about the horizontal center axis of the rotating gear to move relatively synchronously. When the second reciprocating rack moves, it will drive the second moving block fixed with it to move synchronously, so that the rectangular blocking door can be limited and clamped, and then the rectangular blocking door leaf can be prevented from shaking or displacing during the transportation process, thereby improving the stability of the transportation process. At the same time, since the lower part of the second moving block and the upper part of the first moving block are respectively provided with fixed moving blocks slightly larger than the second reciprocating rack and the first reciprocating rack, the limit clamping distance of the first moving block and the second moving block will not be affected.

[0020] 2. The horizontal blocking door leaf transfer vehicle described in the present invention, when the limit clamping plate is in contact with the side surface of the rectangular blocking door, the second motor is started to drive its output shaft to rotate. When the output shaft of the second motor rotates, the bidirectional screw fixedly connected to it will be driven to rotate. Since the threads on the bidirectional screw are opposite, when the bidirectional screw rotates, the first sliding block and the second sliding block threadedly connected to it will be driven to perform relative linear motion along the guide grooves provided in the side surfaces of the limit clamping plate. The relative linear motion of the first sliding block and the second sliding block can ensure that the rectangular blocking door will not be offset during the process of being limit clamped by the two sets of limit clamping plates. At the same time, the relative movement of the first sliding block and the second sliding block can quickly adjust the misalignment of the rectangular blocking door, thereby improving the continuity and efficiency of the transfer.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1

[0035] like Figures 1 to 8 As shown, a horizontal blocking door leaf transfer vehicle according to an embodiment of the present invention comprises a transfer vehicle body 1, the transfer vehicle body 1 comprises a support frame 101, an inner cavity is provided at the bottom of the support frame 101, a steel cable 102 is slidably connected to the top of the support frame 101, and a hook 103 is fixedly connected to one end of the steel cable 102 away from the top of the support frame 101, and a centering fixing mechanism 2 is provided at the lower part of the transfer vehicle body 1;

[0036] The centering fixing mechanism 2 includes a support plate 201 fixedly arranged on the inner cavity side wall of the support frame 101, and two sets of limiting clamping plates 216 are slidingly arranged on the side of the support plate 201. The rectangular blocking door can be fixed and limited by the relative sliding of the two sets of limiting clamping plates 216.

[0037] Specifically, during the transfer process, when the transfer vehicle suddenly brakes and the rectangular blocking door is heavy, the blocking door will swing forward due to inertia. This swing will change the position of its center of gravity, making it unstable. The unstable center of gravity will cause the overall imbalance of the transfer vehicle, thereby affecting the vehicle's controllability and stability. In extreme cases, this will cause the vehicle to overturn or lose control, causing serious safety accidents. At the same time, due to the unstable center of gravity, the rectangular blocking door will fall due to bumps, turns or acceleration during the transfer process, which will not only damage the rectangular blocking door itself, but also cause harm to surrounding equipment and personnel.

[0038] Therefore, the present invention solves this problem by setting up corresponding structures. During use, the horizontal blocking door leaf transfer vehicle described in the present invention needs to be fully inspected. When the transfer vehicle is in good working condition, the staff fixes the hook 103 with the connecting piece on the blocking door, and pulls the blocking door off the ground by retracting the steel cable 102. At this time, the staff pushes the transfer vehicle for transportation along the established route. However, during transportation, the blocking door will be detached from the ground and fixed by the steel cable 102, which will cause shaking. This will cause the center of gravity of the rectangular blocking door to be unstable. The unstable center of gravity will cause the overall imbalance of the transfer vehicle, which will affect the handling and stability of the vehicle. In extreme cases, this will cause the vehicle to overturn or lose control, causing serious safety accidents. At this time, the rectangular blocking door is fixed and limited by the relative movement of the two sets of limiting clamping plates 216, so that the blocking door can be effectively limited to prevent it from shaking or displacement during transportation, thereby improving the stability of the transportation process.

[0039] Embodiment 2

[0040] like Figures 1 to 8 As shown in Comparative Example 1, another embodiment of the present invention is:

[0041] like Figure 5 As shown, the support plate 201 described in this embodiment is fixedly connected to the side wall of the inner cavity of the support frame 101, and a cylinder 202 is fixedly arranged on the side of the support plate 201. A reciprocating telescopic rod 203 is slidably connected inside the cylinder 202, and a fixed moving block 205 is fixedly connected to the end of the reciprocating telescopic rod 203 away from the cylinder 202.

[0042] Specifically, when the rectangular blocking door leaf needs to be transported, the blocking door leaf is first placed completely under the support frame 101 by moving the support frame 101. At this time, the steel cable 102 is lowered and the blocking door leaf is fixed by the hook 103, and the steel cable 102 is tightened to make the blocking door leaf completely free from the support of the ground. At this time, the cylinder 202 is started to make the reciprocating telescopic rod 203 slidingly connected to the inside of the cylinder 202 move toward the direction close to the cylinder 202. When the reciprocating telescopic rod 203 moves, it will drive the fixed moving block 205 fixed thereto to move synchronously, thereby providing corresponding power support for the operation of the subsequent device.

[0043] like Figure 3 and Figure 6 As shown, a first rectangular groove 204 is formed through the side of the support plate 201 in this embodiment, and the fixed moving block 205 is slidably connected in the first rectangular groove 204 . Two sets of guide blocks 206 are fixedly connected to the side of the support plate 201 away from the cylinder 202 .

[0044] Specifically, when the reciprocating telescopic rod 203 pulls the fixed moving block 205 to move toward the cylinder 202, since the fixed moving block 205 slides inside the first rectangular groove 204, the fixed moving block 205 can be limited while not affecting the movement of the fixed moving block 205, thereby ensuring that the fixed moving block 205 always performs reciprocating linear motion.

[0045] like Figure 3 and Figure 6 As shown, the outer surface of the guide block 206 in this embodiment is slidably connected to a first moving block 207, the first moving block 207 is fixedly connected to a side of the first rectangular groove 204 away from the reciprocating telescopic rod 203, and the bottom of the first moving block 207 is fixedly connected to a first reciprocating rack 208.

[0046] Specifically, when the fixed moving block 205 moves along the guide direction of the first rectangular groove 204 toward the cylinder 202, it will drive the first reciprocating rack 208 fixed thereto to move synchronously. At the same time, since the first reciprocating rack 208 is provided with a guide groove that is compatible with the shape and size of the guide block 206 on the side close to the support plate 201, the first reciprocating rack 208 can move in a straight line along the guide of the guide block 206 under the drive of the fixed moving block 205.

[0047] like Figure 3 and Figure 6 As shown, in this embodiment, the first reciprocating rack 208 has a toothed side meshed with a rotating gear 209, a fixed shaft 210 is provided in the middle of the rotating gear 209, the rotating gear 209 is rotatably connected to the outer ring surface of the fixed shaft 210, and the fixed shaft 210 is fixedly connected to the side of the support plate 201 away from the cylinder 202.

[0048] Specifically, when the first reciprocating rack 208 moves synchronously driven by the fixed moving block 205, since the rotating gear 209 rotates on the outer ring surface of the fixed shaft 210, and the fixed shaft 210 is fixed to one side of the support plate 201, it will drive the rotating gear 209 meshing with it to rotate, and then drive the remaining components and the first reciprocating rack 208 to make relative linear motion.

[0049] like Figure 3 and Figure 6 As shown, the outer ring surface of the rotating gear 209 described in this embodiment is meshed with a second reciprocating rack 211, and the end of the second reciprocating rack 211 away from the rotating gear 209 is fixedly connected to the second moving block 212, and the two groups of guide blocks 206 are respectively adapted to the shape of the sliding grooves opened at the bottom of the first reciprocating rack 208 and the second moving block 212.

[0050] Specifically, when the rotating gear 209 rotates, it will drive the second reciprocating rack 211 meshing with it to perform linear motion along the guide of the guide block 206. Since the first reciprocating rack 208 and the second reciprocating rack 211 are symmetrically distributed about the horizontal center axis of the rotating gear 209, the first reciprocating rack 208 and the second reciprocating rack 211 will perform relative linear motion, thereby driving the second reciprocating rack 211 fixed at one end thereof to move synchronously, and then enabling the first moving block 207 and the second moving block 212 to perform relative linear motion.

[0051] like Figure 6 As shown, in this embodiment, a second rectangular groove 213 is opened at the lower part of the second moving block 212, and two groups of the second rectangular grooves 213 are opened. The two groups of the second rectangular grooves 213 are opened at the lower part of the second moving block 212 and the upper part of the first moving block 207 respectively.

[0052] Specifically, since the two groups of second rectangular grooves 213 are respectively opened on the upper part of the first moving block 207 and the lower part of the second moving block 212, and the size of the second rectangular groove 213 is slightly larger than the size of the second reciprocating rack 211 and the first reciprocating rack 208, the first moving block 207 and the second moving block 212 can pass through the second rectangular groove 213 when they move relative to each other, and thus will not affect the clamping limit distance of the first moving block 207 and the second moving block 212.

[0053] like Figure 3 and Figure 4 As shown, in this embodiment, a first motor 214 is fixedly provided on the upper part of the second moving block 212 away from the second rectangular groove 213, and the output shaft of the first motor 214 is fixedly connected to a rotating shaft 215, and the outer ring surface of the rotating shaft 215 is fixedly connected to a limited clamping plate 216.

[0054] Specifically, before the cylinder 202 is started, the first motor 214 is started to make the output shaft of the first motor 214 rotate counterclockwise, thereby driving the rotating shaft 215 fixedly connected to the output shaft to rotate synchronously. At this time, the limit clamping plate 216 fixed on the outer surface of the rotating shaft 215 will also rotate synchronously, and stop rotating when it rotates ninety degrees counterclockwise, so that it and the second moving block 212 maintain a vertical state on the same horizontal plane. Through the rotation of the limit clamping plate 216, the blocking door leaf can be limited and clamped without interfering with the movement of the support frame 101 directly above the blocking door leaf, thereby preventing the rectangular blocking door leaf from shaking or displacement during transportation, thereby improving the stability of the transportation process.

[0055] like Figure 7 and Figure 8As shown, the side of the centering fixing mechanism 2 described in this embodiment is provided with an anti-deviation calibration mechanism 3 for preventing misalignment, and the anti-deviation calibration mechanism 3 includes a second motor 301 . A guide groove 302 is provided in the middle of the side of the limit clamping plate 216 .

[0056] like Figure 7 and Figure 8 As shown, in this embodiment, a first sliding block 303 is slidably connected in the guide groove 302, a bidirectional screw 304 is arranged in the middle of the first sliding block 303, the first sliding block 303 is threadedly connected to the outer ring surface of the bidirectional screw 304, one end of the bidirectional screw 304 is fixed to the output shaft of the second motor 301, and the end of the bidirectional screw 304 away from the first sliding block 303 is threadedly connected to the second sliding block 305, and the second sliding block 305 is slidably connected in the guide groove 302.

[0057] Specifically, when the opposite sides of the two sets of limit clamping plates 216 in the centering and fixing mechanism 2 are in contact with the side surfaces of the rectangular blocking door leaf, the second motor 301 is started to drive the bidirectional screw 304 fixedly connected to the output shaft of the second motor 301 to rotate. When the bidirectional screw 304 rotates, the first sliding block 303 and the second sliding block 305 threadedly connected thereto are driven to move relative to each other along the guide groove 302 to adjust the rectangular blocking door leaf, thereby preventing the rectangular blocking door from being offset when it is limited and fixed. At the same time, the relative movement of the first slider and the second slider can quickly adjust the misalignment of the rectangular blocking door, thereby improving the continuity and efficiency of transportation.

[0058] Working principle: when the rectangular blocking door leaf needs to be transported, first, the blocking door leaf is completely placed directly under the support frame 101 by moving the support frame 101. At this time, the steel cable 102 is lowered and the blocking door leaf is fixed by the hook 103, and the steel cable 102 is tightened to make the blocking door leaf completely separated from the support of the ground. At this time, the cylinder 202 is started to make the reciprocating telescopic rod 203 slidingly connected to the inside of the cylinder 202 move toward the direction close to the cylinder 202. When the reciprocating telescopic rod 203 moves, it will drive the fixed moving block 205 fixed thereto to move synchronously, thereby providing corresponding power support for the operation of the subsequent device.

[0059] When the reciprocating telescopic rod 203 pulls the fixed moving block 205 to move toward the cylinder 202, since the fixed moving block 205 slides inside the first rectangular groove 204, the fixed moving block 205 can be limited while not affecting the movement of the fixed moving block 205, thereby ensuring that the fixed moving block 205 always performs reciprocating linear motion.

[0060] When the fixed moving block 205 moves along the guide direction of the first rectangular groove 204 toward the cylinder 202, it will drive the first reciprocating rack 208 fixed thereto to move synchronously. At the same time, since the first reciprocating rack 208 is provided with a guide groove on the side close to the support plate 201 that is compatible with the shape and size of the guide block 206 fixedly connected to the side of the support plate 201, the first reciprocating rack 208 can move linearly along the guide of the guide block 206 under the drive of the fixed moving block 205.

[0061] When the first reciprocating rack 208 moves synchronously driven by the fixed moving block 205, since the rotating gear 209 rotates on the outer ring surface of the fixed shaft 210, and the fixed shaft 210 is fixed to one side of the support plate 201, it will drive the rotating gear 209 meshing with it to rotate, and then drive the remaining components and the first reciprocating rack 208 to make relative linear motion.

[0062] When the rotating gear 209 rotates, it will drive the second reciprocating rack 211 meshing with it to perform linear motion along the guide of the guide block 206. Since the first reciprocating rack 208 and the second reciprocating rack 211 are symmetrically distributed about the horizontal center axis of the rotating gear 209, the first reciprocating rack 208 and the second reciprocating rack 211 will perform relative linear motion along the guide of the guide block 206, thereby driving the second reciprocating rack 211 fixed at one end thereof to move synchronously, and then enabling the first moving block 207 and the second moving block 212 to perform relative linear motion.

[0063] Since the two groups of second rectangular grooves 213 are respectively opened at the upper part of the first moving block 207 and the lower part of the second moving block 212, and the size of the second rectangular grooves 213 is slightly larger than the size of the second reciprocating rack 211 and the first reciprocating rack 208, the first moving block 207 and the second moving block 212 can pass through the second rectangular grooves 213 when they move relative to each other, and thus will not affect the clamping limit distance of the first moving block 207 and the second moving block 212.

[0064] Before the cylinder 202 is started, the first motor 214 is started to make the output shaft of the first motor 214 rotate counterclockwise, thereby driving the rotating shaft 215 fixedly connected to the output shaft to rotate synchronously. At this time, the limit clamping plate 216 fixed on the outer surface of the rotating shaft 215 will also rotate synchronously, and stop rotating when it rotates ninety degrees counterclockwise, so that it and the second moving block 212 are on the same horizontal plane. The state changes from a parallel state to a vertical state. The rotation of the limit clamping plate 216 can limit and clamp the rectangular blocking door leaf directly above the support frame 101 without hindering the movement of the rectangular blocking door leaf, thereby preventing the rectangular blocking door leaf from shaking or displacement during transportation, thereby improving the stability of the transportation process.

[0065] When the two sets of limiting clamping plates 216 in the centering fixing mechanism 2 are in contact with the side surfaces of the rectangular blocking door leaf, the second motor 301 is started to drive the bidirectional screw 304 fixedly connected to the output shaft of the second motor 301 to rotate. Since the bidirectional screw 304 is contained in the guide groove 302, the rotation of the bidirectional screw 304 is not affected when the rectangular blocking door leaf is in contact with the side walls of the limiting clamping plates 216. When the bidirectional screw 304 rotates, the first sliding block 303 and the second sliding block 305 threadedly connected thereto are driven to rotate along the guide groove 302. During the movement, if the rectangular blocking door leaf is offset, the offset side will conflict with either the guide groove 302 or the second sliding block 305. However, due to the continuous operation of the second motor 301, the guide groove 302 and the second sliding block 305 will continue to move relative to each other and adjust the rectangular blocking door leaf, thereby preventing the rectangular blocking door from offsetting when it is limited and fixed. At the same time, due to the relative movement of the first slider and the second slider, the misalignment of the rectangular blocking door can be quickly adjusted, thereby improving the continuity and efficiency of the transfer.

[0066] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
