Description

Technical Field

[0001] This utility model relates to the field of shuttle vehicles, and more specifically, to an anti-slip locking device for safety protection of shuttle vehicles. Background Technology

[0002] The anti-slip locking device for shuttle car safety protection is a safety protection component of the shuttle car. When the shuttle car is carrying goods along the track in a warehousing and logistics scenario, the anti-slip locking device realizes the functions of braking and deceleration and anti-slip locking after stopping, thereby ensuring safety in both the running and stationary states. Current anti-slip locking devices for shuttle safety protection typically brake by directly locking the wheels with electromagnetic brakes or by having the brake pads directly contact the track. This direct braking method can easily cause the goods on the shuttle to shift or even tip over due to inertia, and it can also increase the friction and wear between the wheels and the track, shorten the service life of components. At the same time, it is difficult to guarantee the anti-slip locking effect after the machine stops, which poses a safety hazard. Utility Model Content

[0003] The purpose of this utility model is to provide an anti-slip locking device for the safety protection of shuttle cars. By using this utility model, the problems in the background mentioned above are that the direct braking method of shuttle cars is prone to causing the goods on the shuttle car to shift or even tip over due to inertia, and it is difficult to guarantee the anti-slip locking effect after the machine stops, which poses a safety hazard.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A shuttle safety protection anti-slip locking device includes a track and a shuttle body that is rotatably connected to the track. Support plates are fixedly connected to the four corners of the bottom of the shuttle body. Lifting plates are slidably connected inside the support plates. Brake pads for braking and locking the shuttle body are fixedly connected inside the lifting plates. Elastic components for resetting the brake pads are provided on both sides of the lifting plates. A motor is provided on one side of the support plate. An intermittent pushing component is fixedly connected to the output end of the motor. A driven component connected to the intermittent pushing component is provided inside the lifting plates.

[0005] Furthermore, the elastic component includes two limiting plates that are fixedly connected to both sides of the lifting plate, and a first spring is fixedly connected to the bottom of each of the two limiting plates, with the other end of the first spring fixedly connected to the inner wall of the support plate.

[0006] Furthermore, the intermittent drive component includes a rotating shaft fixedly connected to the moving end of the motor, a rotating plate fixedly connected to one end of the rotating shaft, and several inclined blocks evenly arranged at the bottom of the rotating plate.

[0007] Furthermore, the driven component includes a sliding frame slidably disposed within the lifting plate, a roller rotatably connected within the sliding frame, an electric push rod installed within the lifting plate, and the movable end of the electric push rod being fixedly connected to the bottom of the sliding frame.

[0008] Furthermore, two drive components are arranged opposite each other inside the lifting plate. Each drive component includes a mounting block fixedly connected inside the lifting plate, and an electromagnet is installed inside the mounting block.

[0009] Furthermore, two first positioning components are slidably arranged inside the lifting plate. The first positioning component includes a first T-shaped slide plate slidably connected inside the lifting plate. A first magnet block is installed on one side of the first T-shaped slide plate. A second spring is fixedly connected to one side of the first T-shaped slide plate, and the other end of the second spring is fixedly connected to the mounting block. A first slot and a second slot are respectively opened on the inner wall of the support plate. The shape of the first T-shaped slide plate matches the shape of the first slot and the second slot.

[0010] Furthermore, two second positioning components are slidably arranged inside the lifting plate. The second positioning components include a second T-shaped slide plate slidably connected inside the lifting plate. A second magnet block is installed on one side of the second T-shaped slide plate, and a third spring is fixedly connected to one side of the second T-shaped slide plate. The other end of the third spring is fixedly connected to the mounting block. Several third slots are opened on both sides of the sliding frame, and the second T-shaped slide plate engages with the third slots.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By having the motor drive the intermittent push component and the driven component to work together, the brake pads intermittently press against the track to achieve point braking. This avoids the shuttle car from shifting or tipping over due to inertia when braking directly. At the same time, the intermittent friction reduces the frictional wear between the brake pads and the track, which can extend the service life of the brake pads and thus improve braking safety and stability.

[0012] The first positioning component facilitates a stable mechanical lock after the shuttle car comes to a stop, preventing accidental slippage due to vibration or external force, thereby improving the safety and stability of the shuttle car when parked.

[0013] When the brake pads wear thin, the drive assembly, in conjunction with the second positioning assembly and the electric push rod, can easily compensate for the wear distance of the brake pads, achieving rapid compensation for the wear of the brake pads without stopping the machine.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] A shuttle car safety protection anti-slip locking device, such as Figure 1As shown, the device includes a track 1 and a shuttle body 2 that is rotatably connected to the track 1. The shuttle body 2 is equipped with a controller that can easily control various electrical components. The controller is existing technology and is not shown in the figure. Support plates 3 are fixedly connected to the four corners of the bottom of the shuttle body 2. Lifting plates 4 are slidably connected to the support plates 3. Brake pads 5 are fixedly connected to the lifting plates 4. The brake pads 5 are used for braking and locking the shuttle body 2. The brake pads 5 are connected to the lifting plates 4 through screws, which facilitates the disassembly and replacement of the brake pads 5.

[0019] Both sides of the lifting plate 4 are equipped with elastic components 6, such as... Figure 4 As shown, the elastic component 6 includes two limiting plates 61 fixedly connected to both sides of the lifting plate 4. A first spring 62 is fixedly connected to the bottom of each limiting plate 61, and the other end of the first spring 62 is fixedly connected to the inner wall of the support plate 3. A motor 7 is provided on one side of the support plate 3, and an intermittent pushing component 8 is rotatably connected to one side of the support plate 3. Figure 3 and Figure 4 As shown, the intermittent drive assembly 8 includes a rotating shaft 81 fixedly connected to the movable end of the motor 7. A rotating plate 82 is fixedly connected to one end of the rotating shaft 81. Several inclined blocks 83 are evenly arranged at the bottom of the rotating plate 82. A driven assembly 9 is installed inside the lifting plate 4. Figure 2 , Figure 4 and Figure 6 As shown, the driven component 9 includes a sliding frame 91 that is slidably disposed within the lifting plate 4, and a roller 92 is rotatably connected within the sliding frame 91.

[0020] When the shuttle body 2 needs to brake, the controller causes the motor 7 to drive the rotating shaft 81, rotating plate 82 and inclined block 83 to rotate. This causes several inclined blocks 83 to intermittently push the roller 92 and sliding frame 91 to move up and down. Through the setting of the limit plate 61 and the first spring 62, the lifting plate 4 and brake pad 5 are raised and lowered back and forth, causing the brake pad 5 to intermittently squeeze the track 1, which facilitates point braking. This allows the shuttle body 2 to achieve smooth deceleration during braking, avoids cargo displacement or tipping due to inertia, reduces friction wear between the brake pad 5 and the track 1, extends service life, and improves braking safety and stability.

[0021] An electric push rod 10 is installed inside the lifting plate 4. The movable end of the electric push rod 10 is fixedly connected to the bottom of the sliding frame 91. Two drive components 20 are arranged opposite each other inside the lifting plate 4, such as... Figure 4 and Figure 5 As shown, the drive assembly 20 includes a mounting block 201 fixedly connected to the lifting plate 4, an electromagnet 202 installed in the mounting block 201, and two first positioning assemblies 30 slidably arranged relative to each other within the lifting plate 4, such as... Figure 4 and Figure 5As shown, the first positioning component 30 includes a first T-shaped slide plate 301 slidably connected to the lifting plate 4. A first magnet block 302 is installed on one side of the first T-shaped slide plate 301. A second spring 303 is fixedly connected to one side of the first T-shaped slide plate 301, and the other end of the second spring 303 is fixedly connected to the mounting block 201. A first slot 31 and a second slot 32 are respectively opened on the inner wall of the support plate 3. The shape of the first T-shaped slide plate 301 matches the first slot 31 and the second slot 32. During the operation of the shuttle body 2, the first T-shaped slide plate 301 is in the state of being engaged with the first slot 31. When the shuttle body 2 needs to be locked, the first T-shaped slide plate 301 is in the state of being engaged with the second slot 32.

[0022] Two second positioning components 40 are relatively slidably arranged inside the lifting plate 4, such as... Figure 5 and Figure 6 As shown, the second positioning component 40 includes a second T-shaped slide plate 401 slidably connected within the lifting plate 4. A second magnet block 402 is installed on one side of the second T-shaped slide plate 401. The magnetic poles of the first magnet block 302 and the second magnet block 402 are opposite to those of the electromagnet 202, so that when the electromagnet 202 attracts the first magnet block 302, it can repel the second magnet block 402. When the electromagnet 202 attracts the second magnet block 402, it can repel the first magnet block 302, which facilitates individual control. A third spring 403 is fixedly connected to one side of the second T-shaped slide plate 401, and the other end of the third spring 403 is fixedly connected to the mounting block 201. Several third slots 93 are provided on both sides of the sliding frame 91. The second T-shaped slide plate 401 engages with the third slots 93, thereby facilitating the fixation of the position of the sliding frame 91.

[0023] When the shuttle body 2 needs to brake, the controller causes the electromagnet 202 to attract the first magnet 302, which in turn moves the first T-shaped slide plate 301, causing it to disengage from the first slot 31 and compress the second spring 303. Subsequently, through the cooperation of the motor 7, the intermittent push component 8, the driven component 9, the lifting plate 4, and the brake pads 5, the shuttle body 2 is braked. When the brakes stop and anti-slip locking is required, the motor 7, in conjunction with the intermittent push component 8 and the driven component 9, drives the lifting plate 4 to descend. At this time, the position of the first T-shaped slide plate 301 corresponds to the second slot 32, and the brake pads 5 are in the state of pressing the track 1. At this time, the controller cancels the attraction of the electromagnet 202 to the first magnet 302, and the reset of the second spring 303 causes the first T-shaped slide plate 301 to engage with the second slot 32, thereby forming a stable and reliable mechanical lock, effectively preventing accidental slippage caused by vibration or external force, thereby improving the parking safety and stability of the shuttle.

[0024] When the brake pads 5 wear down and become thinner after prolonged use, resulting in reduced braking and locking effects, the controller activates the electromagnet 202 to attract the second magnet 402, causing the second T-shaped slide plate 401 to move and disengage from the third slot 93. Simultaneously, the controller compresses the third spring 403. Then, the electric push rod 10 causes the sliding frame 91 to rise within the lifting plate 4. Afterward, the controller releases the electromagnet 202 from the second magnet 402, and the third spring 403 resets, causing the second T-shaped slide plate 401 to engage with the other third slots 93. This adjusts the position of the sliding frame 91 and the roller 92, allowing the motor 7, intermittent push assembly 8, and driven assembly 9 to work together to increase the pushing amplitude on the lifting plate 4 and brake pads 5. This compensates for the wear distance of the brake pads 5, enabling rapid compensation of brake pad wear without stopping the machine, restoring and maintaining stable braking and locking effects, extending the service life of the brake pads 5, reducing replacement frequency, and improving the reliability and ease of maintenance of the equipment.
