Description

Technical Field

[0001] This utility model relates to the field of logistics and warehousing technology, and in particular to a liftable tray support. Background Technology

[0002] In existing industrial production, logistics and warehousing fields, pallet supports are key equipment for supporting and fixing pallets, and their design and usage efficiency directly affect the convenience of material handling and storage.

[0003] However, traditional pallet racks are mostly designed with a fixed height. While this design is simple and low-cost, it reveals several problems in actual use. First, because the height is not adjustable, it cannot be adjusted according to the actual situation when transferring pallets and goods of different sizes or weights. This can cause goods to easily fall off the pallets due to inertia during transfer, potentially damaging the goods and creating safety hazards that threaten the safety of operators. Second, fixed-height pallet racks often occupy a large amount of space when not in use, which is particularly disadvantageous in today's increasingly space-constrained warehouse environment. The inability to effectively fold or retract the rack structure significantly reduces the utilization rate of warehouse space, increases warehousing costs, and also brings inconvenience to warehouse management. Therefore, a liftable pallet rack is proposed to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a liftable tray support.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a liftable tray support, including a bottom support, with rollers fixedly connected to the four corners of the bottom of the bottom support, a push rod fixedly connected to the rear end face of the bottom support, first extension plates fixedly connected to the left and right ends of the bottom support, a hollow shell fixedly connected to the top of the first extension plates, a motor fixedly connected to the front end face of the hollow shell, a bidirectional threaded rod fixedly connected to the output end of the motor, a moving block spirally connected to the outer side of the bidirectional threaded rod, a connecting rod rotatably connected to the top of the moving block, and the end of the connecting rod away from the moving block rotating... A rotating shaft is connected to the rotating shaft. A third extension plate is fixedly connected to the top of the rotating shaft. A top bracket is fixedly connected to the inner end face of the third extension plate. Sliding rods are fixedly connected to the front and rear sides of the bottom of the third extension plate. A compression spring is fixedly connected to the bottom end of the sliding rod. A sleeve is fixedly connected to the bottom end of the compression spring. A second extension plate is fixedly connected to the bottom of the sleeve. A middle bracket is fixedly connected to the inner end face of the second extension plate. Magnetic sheets are fixedly connected between the bottom bracket, the middle bracket, and the top bracket. A material tray body is magnetically fixed to the top of the magnetic sheet. A battery compartment is fixedly connected to the bottom middle of the bottom bracket.

[0006] As a further description of the above technical solution: the end of the bidirectional threaded rod away from the motor is rotatably connected to the rear middle of the hollow shell; the surface of the moving block is slidably connected to the inner wall of the hollow shell; the inner wall of the sleeve is slidably connected to the outer side of the sliding rod; the bottom right front and left rear of the middle support are fixedly connected to the top of the sliding rod; the top right front and left rear of the bottom support are fixedly connected to the bottom of the sleeve. This allows the height and spacing of the bottom support, middle support, and top support to be adjusted, so that the middle support and top support can all have a synchronous lifting effect.

[0007] As a further description of the above technical solution: the number of the sleeve, compression spring and sliding rod is several, and the sleeve, compression spring and sliding rod are distributed between the third extension plate and the second extension plate, and between the middle support and the bottom support, so as to realize the purpose of moving the top support up and down while driving the middle support to move synchronously.

[0008] As a further description of the above technical solution: the inside of the casing has a groove from top to bottom, and the cross-sectional shape of the groove matches the cross-sectional shape of the sliding rod. The compression spring is fixed to the bottom of the groove inside the casing, which allows the middle support to be elastic between the bottom support and the top support, so that it is always kept between the bottom support and the top support.

[0009] As a further description of the above technical solution: the battery compartment is electrically connected to the motor, and the battery in the battery compartment has a capacity of 30000mAh to provide power to the motor. The battery compartment can avoid the movement restrictions caused by wires.

[0010] As a further description of the above technical solution: the bottom support, the middle support, and the top support are all provided with grooves. The grooves are opened from top to bottom, and the cross-sectional shape of the grooves is circular. The depth of the grooves in the bottom support, the middle support, and the top support is 1.2 times the height of the tray body. This allows the tray body to be placed in the grooves, preventing the tray body from easily sliding between the bottom support, the middle support, and the top support due to external forces.

[0011] As a further description of the above technical solution: the bottom of the tray body is made of a magnetically attractable metal, and the shape of the magnetic sheet is the same as the cross-sectional shape of the groove, which is circular. The diameter of the cross-section of the magnetic sheet is 1 / 5 of the groove diameter. The magnetic sheet is used to position the tray body, so that the tray body with a diameter smaller than the groove diameter can also be stably placed in the groove.

[0012] This utility model has the following beneficial effects:

[0013] This utility model features a liftable tray support. Through the design and cooperation of a motor and a bidirectional threaded rod, the device allows for adjustment of the height and spacing of the bottom, middle, and top supports. The middle and top supports can all lift synchronously. Not only do the middle and top supports move downwards during the transfer of the tray body and the goods it carries, thus restricting the goods and preventing them from detaching from the tray body due to inertia, but the device also reduces the distance between the movable and fixed supports when not using fixed and movable supports, thereby reducing the overall footprint and making it suitable for widespread use.

Detailed Implementation

[0021] Reference Figures 1 to 5This utility model provides a liftable tray support, including a bottom support 1. Rollers 2 are fixed to the four corners of the bottom of the bottom support 1 by bolts. A push rod 3 is welded to the rear end of the bottom support 1. First extension plates 5 are welded to the left and right ends of the bottom support 1. A hollow shell 6 is welded to the top of the first extension plates 5. A motor 7 is fixed to the front end of the hollow shell 6 by bolts. A bidirectional threaded rod 14 is provided at the rear top of the output shaft of the motor 7. The outer side of the bidirectional threaded rod 14 penetrates the interior of the moving block 15 and is helical with the internal thread of the moving block 15. A rotatable connecting rod 8 is provided at the top of the moving block 15. The connecting rod 8 is located away from the moving block 15. A rotating shaft 16 is set at one end, and a third extension plate 9 is set at the top of the rotating shaft 16. A top bracket 10 is welded to the inner end face of the third extension plate 9. A sliding rod 18 is fixed to the front and rear sides of the bottom of the third extension plate 9 by bolts. A compression spring 17 is welded to the bottom of the sliding rod 18. A housing 11 is welded to the bottom of the compression spring 17. A second extension plate 12 is fixed to the bottom of the housing 11 by bolts. A middle bracket 13 is welded to the inner end face of the second extension plate 12. A magnetic sheet 20 is set in the middle of the bottom bracket 1, the middle bracket 13 and the top bracket 10. The top of the magnetic sheet 20 magnetically fixes the bottom of the material tray body 4. The battery compartment 19 is fixed to the middle of the bottom of the bottom bracket 1 by bolts.

[0022] The end of the bidirectional threaded rod 14 away from the motor 7 is rotatably connected to the rear center of the hollow shell 6. The surface of the moving block 15 is slidably connected to the inner wall of the hollow shell 6. The inner wall of the sleeve 11 is slidably connected to the outer side of the sliding rod 18. The bottom right front and left rear of the middle bracket 13 are fixedly connected to the top of the sliding rod 18. The top right front and left rear of the bottom bracket 1 are fixedly connected to the bottom of the sleeve 11. This allows the bottom bracket 1, the middle bracket 13, and the top bracket 10 to be adjusted in height and spacing, so that the middle bracket 13 and the top bracket 10 can all have a synchronous lifting effect.

[0023] As a further implementation of the above technical solution: the number of housing 11, compression spring 17 and sliding rod 18 is several, and the housing 11, compression spring 17 and sliding rod 18 are distributed between the third extension plate 9 and the second extension plate 12, and between the middle support 13 and the bottom support 1, so as to realize the purpose of driving the middle support 13 to move synchronously while the top support 10 moves up and down.

[0024] As a further implementation of the above technical solution: a groove is provided inside the casing 11 from top to bottom, and the cross-sectional shape of the groove matches the cross-sectional shape of the sliding rod 18. The compression spring 17 is fixed to the bottom of the groove inside the casing 11, so that the middle support 13 can be elastic between the bottom support 1 and the top support 10, so that it is always kept between the bottom support 1 and the top support 10.

[0025] As a further implementation of the above technical solution: the battery compartment 19 is electrically connected to the motor 7, and the battery capacity in the battery compartment 19 is 30000mAh to provide power to the motor 7. The setting of the battery compartment 19 can avoid the movement restrictions caused by wires.

[0026] As a further implementation of the above technical solution: the bottom support 1, the middle support 13 and the top support 10 are all provided with grooves. The grooves are opened from top to bottom, and the cross-sectional shape of the grooves is circular. The depth of the grooves opened in the bottom support 1, the middle support 13 and the top support 10 is 1.2 times the height of the tray body 4, so that the tray body 4 can be placed in the grooves, and the purpose of preventing the tray body 4 from being easily slipped by external forces between the bottom support 1, the middle support 13 and the top support 10.

[0027] As a further implementation of the above technical solution: the bottom of the tray body 4 is made of a magnetically attractable metal, and the shape of the magnetic sheet 20 is the same as the cross-sectional shape of the groove. The cross-sectional diameter of the magnetic sheet 20 is 1 / 5 of the groove diameter. The magnetic sheet 20 is used to position the tray body 4, so that the tray body 4 with a diameter smaller than the groove diameter can also be stably placed in the groove.

[0028] Working principle:

[0029] When the tray body 4 needs to be removed from the groove at the center of the bottom support 1, the middle support 13, and the top support 10, the distance between the bottom support 1, the middle support 13, and the top support 10 needs to be increased. The motors 7 on the left and right ends of the bottom support 1 are activated. The motors 7 drive the bidirectional threaded rod 14 at the output end to rotate inside the hollow shell 6. Meanwhile, the moving block 15 on the outer side of the bidirectional threaded rod 14 moves towards the center inside the hollow shell 6, simultaneously driving the connecting rod 8 at the top of the moving block 15 to lift upwards. The rotating shaft 16 at the top of the connecting rod 8 drives the third extension plate 9 and the top support 10 on the inner end face of the third extension plate 9 to move upwards. At the same time, the sliding rods 18 on the front and rear sides of the bottom of the third extension plate 9 slide upwards along the inside of the casing 11 under the rebound action of the compression spring 17. After the second extension plate 12 directly below the third extension plate 9 stops being pressured, it is pushed upwards by the bottom... The compression spring 17 in the top sleeve 11 of the support 1 moves upward synchronously with the sliding rod 18 fixed at the bottom of the middle support 13. At this time, the gap between the bottom support 1, the middle support 13 and the top support 10 is opened, and the operator can directly remove the tray body 4 from the groove. After the tray body 4 is separated from the magnetic sheet 20 in the groove, the operator places the goods on top of the tray body 4 and then puts it back into the groove at the center of the bottom support 1, the middle support 13 and the top support 10. The reverse motor 7 shortens the distance between the bottom support 1, the middle support 13 and the top support 10, so that the middle support 13 can squeeze and restrict the goods placed on top of the bottom support 1 and the top support 10 can squeeze and restrict the goods to a certain extent, preventing the goods from falling off the tray body 4 due to inertia during transportation.
