Description

Technical Field

[0001] The utility model relates to the technical field of shuttle vehicles, in particular to a shuttle vehicle maintenance device. Background Art

[0002] In automated warehousing systems, shuttles are often used to transport materials. The shuttle moves to the bottom of the material, and then the shuttle's bracket moves upward to lift the material. After lifting the material, the shuttle moves along the guide rail. After moving the material to the storage position, the bracket on the shuttle moves downward to place the material in the designated storage position. The entire automated warehousing system needs to be equipped with multiple shuttles that move on mutually staggered guide rails to achieve the transfer and storage of materials at different positions. The shuttle needs to be repaired during use. During the repair process, if a shuttle fails and cannot be moved, a traction device is required to tow it. The traction device is used to tow the shuttle to the maintenance area for subsequent maintenance operations. After the maintenance is completed, the shuttle can be sent back to the guide rail, and the shuttle is placed on the traction device. The rollers at the bottom of the traction device move on the guide rail to achieve traction of the shuttle. The traction device is the shuttle maintenance device.

[0003] To this end, the patent with publication number CN219688405U discloses a traction device for the maintenance of a shuttle vehicle, including a support plate with a J-shaped structure, the support plate including a horizontal first load-bearing support block, a second load-bearing support block and a vertical load-bearing block, the upper surface of the first load-bearing support block is provided with a plurality of positioning blocking structures, the lower surface of the first load-bearing support block is provided with a driven wheel structure, and the second load-bearing support block is provided with a plurality of guide wheels. The benefits of the utility model are: the rolling friction of the traction device replaces the resistance generated by the motor of the driving wheel when the on-rail shuttle vehicle moves, thereby reducing the thrust required to push the non-powered shuttle vehicle on the track; saving the time consumption generated when the lifting device moves, and can further reduce the influence of unreliable factors generated by the lifting device when transferring the shuttle vehicle, thereby reducing the possibility of secondary damage during maintenance.

[0004] When in use, the above patent places the shuttle on a support plate, which supports the shuttle, and then positions the shuttle by a positioning and blocking structure on the support rod. However, during the towing process of the shuttle, the U-shaped mounting plate of the positioning and blocking structure is used for simple support and positioning, and the shuttle is not effectively fixed. During the towing process of the shuttle, the shuttle will still shake on the support plate, and the stability during the towing process needs to be improved. Therefore, the present application provides a shuttle maintenance device to meet the needs. Utility Model Content

[0033] like Figure 1-Figure 6 As shown, an embodiment of the utility model provides a shuttle vehicle maintenance device, including a shuttle vehicle body 1, and also including:

[0034] A traction seat 2 is provided on which the shuttle body 1 is placed. A wheel groove 8 is provided on the traction seat 2. The rollers of the shuttle body 1 are movably connected to the inner wall of the wheel groove 8. The number and position of the wheel groove 8 correspond to the number and position of the rollers installed at the bottom of the shuttle body 1, and are used to realize the preliminary positioning of the shuttle body 1. The traction seat 2 is internally rotatably connected with a wheel axle 5. The end of the wheel axle 5 is fixed with a moving wheel 3. There are two wheel axles 5, and there are two moving wheels 3 at each wheel axle 5. A handle 7 is fixed on the traction seat 2. The traction seat 2 is used to realize the traction of the shuttle body 1. After being towed to the designated area, it can be repaired.

[0035] The clamping mechanism 4 includes a driving member 41 arranged inside the traction seat 2. There are two driving members 41, and the two driving members 41 are symmetrically arranged with the central vertical plane passing through the traction seat 2 as the symmetry plane. A movable rod 42 is fixed to the telescopic end of the driving member 41. A slide groove is provided on the traction seat 2. A connecting block 44 that moves along the inner wall of the slide groove is fixed on the movable rod 42. The slide groove provides space for the movement of the connecting block 44. A square bar 45 is fixed on the connecting block 44. A buffer bar 46 for clamping and positioning the shuttle body 1 is fixed on the side of the square bar 45. The buffer bar 46 is used to prevent the square bar 45 from hard contact with the surface of the shuttle body 1, thereby protecting the shuttle body 1.

[0036] like Figure 1 and Figure 2 As shown, in this embodiment, the inner wall of the wheel groove 8 is a curved surface, and the shape of the wheel groove 8 is adapted to the shape of the roller of the shuttle body 1. The wheel groove 8 with a curved inner wall increases the contact area with the roller of the shuttle body 1, thereby achieving stable positioning of the shuttle body 1.

[0037] like Figure 3 As shown, in this embodiment, a fixing plate 43 is fixed inside the traction seat 2, and the driving member 41 is fixed to the side of the fixing plate 43. The driving member 41 is fixed in the traction seat 2 in a horizontal state through the fixing plate 43, so that the push rod of the driving member 41 drives the movable rod 42 to move horizontally when it is extended or retracted.

[0038] like Figure 6As shown, in the present embodiment, the buffer strip 46 includes a rubber strip 461 fixed on the side of the square strip 45, the side of the rubber strip 461 is movably connected to the side of the shuttle body 1, a cavity 463 is provided inside the rubber strip 461, and protrusions 462 are fixed on both sides of the inner wall of the cavity 463. The rubber strip 461 is used to prevent the square strip 45 from making hard contact with the shuttle body 1, and the cavity 463 is used to accommodate the protrusions 462. The protrusions 462 are also made of rubber material. The protrusions 462 on both sides of the inner wall of the cavity 463 are aligned, and the protrusions 462 can undergo elastic deformation, which is used for buffering when the two buffer strips 46 clamp the shuttle body 1, thereby preventing the shuttle body 1 from being hard clamped.

[0039] like Figure 6 As shown, in the present embodiment, the protrusion 462 is in the shape of a truncated cone, and an elliptical through hole arranged vertically is opened on the protrusion 462. The protrusion 462 is in the shape of a truncated cone, and the truncated cone shape can realize stable buffering when clamping the shuttle body 1. The elliptical through hole provides space for the protrusion 462 to be deformed under force, thereby improving the buffering capacity of the protrusion 462.

[0040] like Figure 3 and Figure 5 As shown, in this embodiment, a locking mechanism 6 is provided on the wheel axle 5, and the locking mechanism 6 includes a second driving member 62 fixed to the top of the inner wall of the traction seat 2, a connecting strip 63 is fixed to the telescopic end of the second driving member 62, and a locking block 61 for locking the wheel axle 5 is fixed to the bottom of the connecting strip 63. A proximity switch sensor 64 is embedded on the top of the inner wall of the handle 7, and the proximity switch sensor 64 is electrically connected to the second driving member 62. When the maintenance personnel holds the handle 7, the maintenance personnel's finger contacts the proximity switch sensor 64. The proximity switch sensor 64 sends a signal to the processor, which controls the push rod of the second driving member 62 to shorten, so that the connecting strip 63 drives the locking block 61 to move upward and separate from the left wheel axle 5. After separation, the traction seat 2 can be moved. When the maintenance personnel's finger is separated from the proximity switch sensor 64, the push rod of the second driving member 62 extends and drives the locking block 61 to move downward through the connecting strip 63 to press against the wheel axle 5. Locking the wheel axle 5 can prevent the movable wheel 3 on the left from rotating at will, thereby stopping the movement of the traction seat 2.

[0041] like Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, driving member 1 41 and driving member 2 62 are both electric push rods, driving member 1 41 is in a horizontal state, and driving member 2 62 is in a vertical state. Driving member 1 41 is used to drive the movable rod 42 to move horizontally, and driving member 2 62 is used to drive the locking block 61 to move vertically.

[0042] like Figure 5As shown, in this embodiment, the inner wall of the locking block 61 is a curved surface, which is used to increase the contact area with the axle 5, increase the contact area between the locking block 61 and the axle 5, and improve the locking ability of the axle 5.

[0043] Working principle: Hold the handle 7 and make the maintenance personnel's finger fit with the proximity switch sensor 64. After fitting, the push rod of the second driving member 62 shortens and drives the locking block 61 to move upward through the connecting strip 63. The locking block 61 is separated from the wheel axle 5. After separation, the handle 7 can be held to move the traction seat 2 to the damaged shuttle vehicle body 1. Then release the handle 7, and the maintenance personnel's finger is separated from the proximity switch sensor 64. After separation, the push rod of the second driving member 62 extends and drives the locking block 61 to move downward against the wheel axle 5, so as to lock the moving wheel 3.

[0044] Then, the shuttle body 1 is lifted and placed on the traction seat 2, so that the roller of the shuttle body 1 fits with the inner wall of the wheel groove 8 on the traction seat 2, and the initial positioning of the shuttle body 1 is achieved through the wheel groove 8, and then the two driving members 41 are started at the same time, so that the push rods of the two driving members 41 are shortened, thereby driving the two movable rods 42 to move toward the center direction of the traction seat 2, and the two movable rods 42 respectively drive the square bars 45 to move toward the shuttle body 1 through the connecting block 44, and the square bars 45 drive the buffer bars 46 to fit with the surface of the shuttle body 1, and the clamping and positioning of the shuttle body 1 is achieved through the cooperation of the two buffer bars 46;

[0045] After clamping and positioning, you can hold the handle 7 to pull the traction seat 2 to move, and the moving wheel 3 at the bottom of the traction seat 2 moves along the guide rail to achieve traction of the shuttle body 1. Because the guide rails for the movement of the shuttle body 1 are usually staggered, when the towed shuttle body 1 is blocked by other shuttle bodies 1 in front of it, release the handle 7, and the driving member 62 can drive the locking block 61 to move downward to resist the wheel axle 5, locking the moving wheel 3, thereby achieving the timely stop of the traction seat 2, preventing the traction vehicle from colliding with other shuttle bodies 1, and ensuring the safety during traction;

[0046] When other shuttle bodies 1 pass in front, the user can continue to hold the handle 7 to pull the traction seat 2 to achieve traction of the shuttle body 1. After traction to the designated location, start the driving member 41, so that the push rod of the driving member 41 extends to drive the movable rod 42 to move away from the shuttle body 1, and the movable rod 42 and the connecting block 44 drive the square bar 45 to move away from the shuttle body 1. The square bar 45 drives the buffer bar 46 to separate from the shuttle body 1. After separation, the shuttle body 1 can be removed from the traction seat 2, and then the shuttle body 1 can be repaired.

[0047] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, the specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
