Description

Technical Field

[0001] This utility model relates to the field of transport shuttle technology, and in particular to a limiting device for a transport shuttle. Background Technology

[0002] A material handling shuttle is an intelligent material handling device used in automated warehousing and logistics systems. It is mainly used to efficiently and accurately transport goods within shelves, production lines, or warehouses. Its main components include: vehicle frame, drive system, navigation system, etc.

[0003] Existing technologies, such as the utility model with publication number CN212798163U, disclose a limiting device for a transport shuttle. This utility model, belonging to the mechanical field, includes a shuttle. Hydraulic actuators A are detachably connected to both sides of the shuttle. A crossbar A is embedded in one end of each hydraulic actuator A, and a vertical plate A is fixedly connected to one end of each crossbar A. Hydraulic actuators B are detachably connected to the front and rear ends of the shuttle. A crossbar B is embedded in one end of each hydraulic actuator B. One end is fixedly connected to a vertical plate B. When the shuttle needs to be limited, the power output terminals of hydraulic actuators A and B are connected by a control switch in a time-sharing manner. When the width of the shuttle needs to be increased for the limit, the hydraulic actuators A on the left and right sides of the shuttle move through electric cylinders, causing the horizontal bar A embedded in its surface to move back and forth in the horizontal direction to increase or decrease its length. The electric cylinder of hydraulic actuator B moves, causing the horizontal bar B embedded in it to extend or retract horizontally, so that the shuttle has a good limiting measure when in use.

[0004] The following defects were found in the above-mentioned issues: In existing technologies, material handling shuttles are frequently used for transporting and storing goods. However, in certain transportation environments, material handling shuttles may collide with personnel, other equipment, or building structures due to environmental factors or positioning system malfunctions. Existing material handling shuttles lack adequate limiting measures to prevent collisions when they are about to collide with personnel, other equipment, or building structures. This results in damage to the shuttle body during collisions, leading to low material handling efficiency and significantly increased costs. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing transport shuttles, which lack adequate limiting measures to prevent collisions when the shuttle body is about to collide with personnel, other equipment, or building structures. This results in damage to the shuttle body during collisions, leading to low transport efficiency and significantly increased costs. Therefore, this utility model proposes a limiting device for transport shuttles.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a limiting device for a transport shuttle, comprising a vehicle body and rollers. The lower surface of the vehicle body is provided with a limiting device, which includes two sliding grooves. Rectangular strips are slidably connected to the inner walls of the two sliding grooves. A cylinder is fixedly connected to the lower surface of the rectangular strips. A connecting block is fixedly connected to the arc surface of the cylinder. The connecting block is slidably connected to the lower surface of the vehicle body. A rectangular block is fixedly connected to the lower surface of the vehicle body. A first screw is threadedly connected to one side of the two connecting blocks that are close to each other. The first screw is rotatably connected to the rectangular block. Two baffles are fixedly connected to the lower surface of the vehicle body. Both baffles are rotatably connected to the first screw. A circular groove is opened on one side of one of the baffles. A motor is fixedly connected to the inner wall of the circular groove. The output end of the motor is fixedly connected to the first screw. A limiting plate is fixedly connected to one side of each of the two rectangular strips. Two anti-slip grooves are fixedly connected to the upper surface of the vehicle body.

[0007] The effect achieved by the above components is that the motor can be controlled to rotate and drive the first screw to make the two limiting plates slide outward along the slide groove, thereby limiting the vehicle body and preventing the vehicle body from leaving the track or deviating from the predetermined area.

[0008] Preferably, a plurality of rubber strips are fixedly connected to the sides of the two limiting plates that are far apart from each other, and the plurality of rubber strips are evenly distributed on the limiting plates.

[0009] The effect achieved by the above components is that when the two limiting plates come into contact with the boundary or other objects, the pressure on the limiting plates can be buffered by the several rubber strips on the limiting plates to prevent damage to the limiting plates.

[0010] Preferably, a protective cover is slidably connected to the inner wall of the circular groove, and the protective cover completely covers the motor.

[0011] The effect achieved by the above components is that the motor is relatively expensive, and a protective cover can be used to protect the motor.

[0012] Preferably, a plurality of heat dissipation holes are provided on one side of the protective cover, and the plurality of heat dissipation holes are evenly distributed on the protective cover.

[0013] The effect achieved by the above components is as follows: when the motor operates for a long time, it will generate hot air at a high temperature. The heat dissipation holes allow the hot air to dissipate through the holes, thus achieving the effect of heat dissipation.

[0014] Preferably, cleaning devices are provided on both sides of the vehicle body. The cleaning device includes a rectangular plate, which is fixedly connected to the vehicle body. Two sliding holes are opened on the upper surface of the rectangular plate. Two round rods are slidably connected to the inner walls of the two sliding holes. A frustum is fixedly connected to the lower surface of each of the two round rods. A cleaning brush is fixedly connected to the lower surface of the frustum. A connecting plate is fixedly connected to the upper surface of the two round rods. A second screw is threaded to one side of the connecting plate. The second screw is rotatably connected to the rectangular plate. A knob is fixedly connected to the end of the second screw away from the rectangular plate.

[0015] The effect achieved by the above components is as follows: when the vehicle body is moving, foreign objects on the track or the movement path may cause the wheels to jam. The second screw is used to adjust the cleaning brush to the front of the roller and make it contact the track or movement path. When the vehicle body is about to move, the cleaning brush will clean up the debris in front of the roller.

[0016] Preferably, an anti-wear sleeve is fixedly connected to the inner wall of the sliding hole, and the anti-wear sleeve is circular.

[0017] The effect achieved by the above components is that when the round rod slides between the round rod and the rectangular plate for a long time, wear is inevitable. However, the wear-resistant sleeve can reduce the degree of wear between the round rod and the rectangular plate.

[0018] Preferably, four arc grooves are provided on one side of the knob, and the four arc grooves are evenly distributed around the circumference of the knob.

[0019] The effect achieved by the above components is that when the second screw is rotated using the knob, the four arc-shaped slots allow fingers to be easily inserted, making operation simpler and more convenient.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] In this utility model, when using a transport shuttle for transport work, it is necessary to plan the movement path of the vehicle body on the track. However, during the movement, the vehicle body may deviate from the track or movement path due to collisions with external objects or system malfunctions, resulting in transport work failure. By setting a limiting device, the width of the vehicle body can be increased to restrict the movement of the vehicle body within a specific space, thus preventing the vehicle body from deviating. The main operating steps are as follows: When it is necessary to set the limiting device for the vehicle body, the motor needs to be controlled to rotate. When the motor rotates, it will drive the first screw to rotate. When the first screw rotates between the two baffles and the rectangular block, the first screw itself will not move laterally, but the two connecting blocks connected to the first screw will start to move away from each other due to the rotation of the first screw. Meanwhile, two cylinders connected to the two connecting blocks are located below the rectangular strips and are fixedly connected to them. The two rectangular strips are located in two grooves under the vehicle body. So when the two connecting blocks move away from each other due to the rotation of the first screw, the two rectangular strips will also slide away from each other along the grooves. While the rectangular strips are sliding, the two limiting plates will slide away from each other along with the sliding of the rectangular strips. When they slide to the appropriate position, the control motor is stopped, and the limiting plates will stop moving. This completes the limiting operation. The protective cover on the motor can also be removed from the circular groove. During use, it protects the motor from damage. The several heat dissipation holes on the protective cover can dissipate the heat generated by the motor operation. The rubber strip located on the side of the two limiting plates that is away from each other can buffer the pressure on the limiting plates when they collide, thus protecting the limiting plates.

[0022] In this invention, a cleaning device is installed. When the transport shuttle is performing transport work, it needs to move on a track or a designated path. However, in a dirty or messy environment, debris particles may accumulate on the track, causing the shuttle's rollers to jam and preventing the shuttle from carrying out transport work. The cleaning device cleans away these debris particles from the track or designated path, allowing the transport work to proceed normally. The specific operating steps are as follows: Before using the shuttle for transport work, the knob located at the end of the second screw furthest from the rectangular plate can be turned to rotate the second screw. When the second screw rotates, it will drive the connecting... As the connecting plate moves downwards, it presses down on the two round rods, which then slide downwards. Since the two round rods are located in the two sliding holes in the rectangular plate, they slide downwards along the sliding holes. When the two round rods slide down until the cleaning brush connected to them can fully contact the track or the designated path, the knob can be turned to stop the two round rods from sliding. The four arc grooves on one side of the knob allow fingers to be inserted into them when turning the knob, making it easier to apply force. The anti-wear sleeves between the round rods and the sliding holes reduce the degree of wear between them. Attached Figure Description

Detailed Implementation

[0028] Reference Figure 1As shown, this utility model provides a technical solution: a limiting device for a transport shuttle, including a vehicle body 1, rollers 2, a limiting device 3 on the lower surface of the vehicle body 1, and cleaning devices 4 on both sides of the vehicle body 1.

[0029] The specific settings and functions of the limiting device 3 and the cleaning device 4 will be explained below.

[0030] Reference Figure 2 and Figure 3 As shown, in this embodiment: the limiting device 3 includes two sliding grooves 301, and rectangular bars 302 are slidably connected to the inner walls of both sliding grooves 301. A cylinder 303 is fixedly connected to the lower surface of the rectangular bars 302, and a connecting block 304 is fixedly connected to the arc surface of the cylinder 303. The connecting block 304 is slidably connected to the lower surface of the vehicle body 1, and a rectangular block 305 is fixedly connected to the lower surface of the vehicle body 1. A first screw 306 is threadedly connected to the side of the two connecting blocks 304 that is close to each other. Two baffles 307 are fixedly connected to the lower surface of the vehicle body 1, which is rotatably connected to the rectangular block 305. Both baffles 307 are rotatably connected to the first screw 306. A circular groove 308 is opened on one side of one of the baffles 307. A motor 309 is fixedly connected to the inner wall of the circular groove 308. The output end of the motor 309 is fixedly connected to the first screw 306. Limiting plates 314 are fixedly connected to one side of each of the two rectangular bars 302. Two anti-slip grooves 313 are fixedly connected to the upper surface of the vehicle body 1. The motor 309 can be controlled to rotate and drive the first screw 306 to make the two limiting plates 314 slide outward along the slide groove 301, thereby limiting the vehicle body 1 and preventing the vehicle body 1 from leaving the track or deviating from the predetermined area. Several rubber strips 312 are fixedly connected to the side of the two limiting plates 314 that are far apart from each other. The rubber strips 312 are evenly distributed on the limiting plates 314. When the two limiting plates 314 come into contact with the boundary or other objects, the pressure on the limiting plates 314 can be buffered by several rubber strips 312 on the limiting plates 314 to prevent damage. A protective cover 310 is slidably connected to the inner wall of the circular groove 308, completely enclosing the motor 309. The motor 309 is relatively expensive, and the protective cover 310 protects it. Several heat dissipation holes 311 are evenly distributed on one side of the protective cover 310. After prolonged operation, the motor 309 generates high-temperature air, which is dissipated through the heat dissipation holes 311, achieving a cooling effect.

[0031] Reference Figure 4As shown in this embodiment: Cleaning devices 4 are provided on both sides of the vehicle body 1. The cleaning device 4 includes a rectangular plate 401, which is fixedly connected to the vehicle body 1. Two sliding holes 402 are opened on the upper surface of the rectangular plate 401. Two round rods 404 are slidably connected to the inner walls of the two sliding holes 402. A frustum 405 is fixedly connected to the lower surface of each of the two round rods 404. A cleaning brush 406 is fixedly connected to the lower surface of the frustum 405. A connecting plate 407 is fixedly connected to the upper surface of the two round rods 404. A second screw 408 is threadedly connected to one side of the connecting plate 407. The second screw 408 is rotatably connected to the rectangular plate 401. A knob 409 is fixedly connected to the end of the second screw 408 away from the rectangular plate 401. When the vehicle body 1 is moving, foreign objects on the track or movement path may cause the wheels to jam. The second screw 408 adjusts the cleaning brush 406 to position it in front of the roller 2 and into contact with the track or movement path. When the vehicle body 1 needs to move, the cleaning brush 406 cleans the debris in front of the roller 2. An anti-wear sleeve 403 is fixedly connected to the inner wall of the sliding hole 402. The anti-wear sleeve 403 is annular. When the round rod 404 slides between the round rod 404 and the rectangular plate 401 for a long time, wear is inevitable. The anti-wear sleeve 403 reduces the degree of wear between the round rod 404 and the rectangular plate 401. Four arc-shaped grooves 410 are evenly distributed around the circumference of the knob 409 on one side. When the second screw 408 is rotated using the knob 409, the four arc-shaped grooves 410 allow fingers to easily enter, making operation simpler and more convenient.

[0032] Working principle: In this utility model, when using a transport shuttle for transport work, it is necessary to plan the movement path of the vehicle body 1 on the track. However, during the movement, the vehicle body 1 may deviate from the track or movement path due to collisions with external objects or system malfunctions, resulting in transport work failure. By setting a limiting device 3, the width of the vehicle body 1 can be increased to restrict the movement of the vehicle body 1 within a specific space, preventing the vehicle body 1 from deviating. The main operating steps are as follows: When it is necessary to set the limiting device for the vehicle body 1, the motor 309 needs to be controlled to rotate. While the motor 309 rotates, it will drive the first screw 306 to rotate. When the first screw 306 rotates in the two baffles 307 and the rectangular block 305, the first screw 306 itself will not move laterally, but the two connecting blocks 304 connected to the first screw 306 will start to move away from each other due to the rotation of the first screw 306. Meanwhile, two cylinders 303 connected to the two connecting blocks 304 are located below and fixedly connected to the rectangular strip 302. The two rectangular strips 302 are located in the two sliding grooves 301 below the vehicle body 1. Therefore, when the two connecting blocks 304 move away from each other due to the rotation of the first screw 306, the two rectangular strips 302 will also slide away from each other along the sliding grooves 301. While the rectangular strips 302 are sliding, the two limiting plates 314 will slide away from each other along with the sliding of the rectangular strips 302. When they slide to the appropriate position, the control circuit stops. When the motor 309 rotates, the limiting plate 314 will stop moving, thus completing the limiting operation. The protective cover 310, which is fitted onto the motor 309, can also be removed from the circular groove 308. During use, it protects the motor 309 from damage. The several heat dissipation holes 311 on the protective cover 310 can dissipate the heat generated by the operation of the motor 309. The rubber strip 312 located on the side of the two limiting plates 314 that are far apart can buffer the pressure on the limiting plates 314 when they collide, thereby protecting the limiting plates 314.

[0033] In this utility model, by setting up a cleaning device 4, when the transport shuttle is performing transport work, it needs to move on the track or a designated path. However, in a relatively dirty and messy environment, there may be debris particles on the track, causing the rollers 2 of the vehicle body 1 to get stuck on the track, preventing the vehicle body 1 from carrying out transport work. By setting up the cleaning device 4, the debris particles on the track or designated path can be cleaned up, allowing the transport work to proceed normally. The specific operation steps are as follows: Before using the vehicle body 1 for transport work, the knob 409 located at the end of the second screw 408 away from the rectangular plate 401 can be turned to drive the second screw 408 to rotate. When the second screw 408 rotates, it will drive the connecting plate 407 to move downwards slowly. As the device moves downward, the connecting plate 407 presses down on the two round rods 404, which then slide downward. Since the two round rods 404 are located in the two sliding holes 402 in the rectangular plate 401, they slide downward along the sliding holes 402. When the two round rods 404 slide downward until the cleaning brush 406 connected to them can fully contact the track or the designated path, the knob 409 can be turned to stop the two round rods 404 from sliding. The four arc grooves 410 on one side of the knob 409 allow fingers to be inserted into them when the knob 409 is turned, making it easier to apply force. The anti-wear sleeve 403 between the round rods 404 and the sliding holes 402 reduces the wear between them.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection within a component, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
