Description

Technical Field

[0001] This utility model relates to the field of box handling technology, specifically a thin-walled box transfer tool. Background Technology

[0002] In industrial transport, thin-walled boxes are subject to extremely high requirements for transport stability due to their thin material and low strength. Even a slight loss of speed control can cause scratches and deformation. Currently, the sliding wheels of transport tools are mostly designed with low resistance to facilitate pushing. However, thin-walled boxes are lightweight and have low inertia. When encountering uneven ground, uneven thrust, or starting, stopping, or turning, the wheels can easily cause the box to slide rapidly. This not only makes it difficult to control the path but may also cause collisions with equipment or personnel, resulting in damage to the box and its contents.

[0003] While existing tools can be equipped with manual brake pads to increase resistance and limit speed, they require manual judgment to trigger, resulting in a response delay. Furthermore, the brake pad resistance is fixed and cannot be adaptively adjusted according to the size and weight of the box. Either the resistance is insufficient and the speed limit is ineffective, or the resistance is too great and affects the pushing. At the same time, the instantaneous impact force of the rigid brake pads may also aggravate the deformation of the box. It is always difficult to balance the transfer efficiency and protection requirements. The wheel resistance adjustment process urgently needs optimization. Utility Model Content

[0004] The purpose of this invention is to provide a thin-walled box transfer tool to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A thin-walled box transport tool includes a sliding frame, with multiple rolling wheels rotatably connected to the outer wall of the sliding frame, and multiple rotating rods rotatably connected to the outer wall of the sliding frame. The outer wall of each rotating rod is fixedly connected to the interior of two adjacent rolling wheels, and two electrically retractable legs are rotatably connected to the bottom of the sliding frame.

[0007] The bottom of the sliding frame is also rotatably connected to two mounting legs, and an abutment frame is fixedly connected between the two mounting legs. A speed reduction mechanism is installed between the outer wall of each rotating rod and the sliding frame, and an emergency stop mechanism is also fixedly installed between the rotating rod and the sliding frame.

[0008] As a further aspect of this solution, the speed reduction mechanism includes a connecting block, which is fixedly connected to the outer wall of the rotating rod by bolts, and the connecting block has multiple sliding columns with reset function slidably connected inside.

[0009] As a further aspect of this solution, the outer wall of the sliding frame is also fixedly connected to two electric telescopic arms, and a connecting plate is fixedly connected between the two electric telescopic arms. A plurality of liquid storage boxes are fixedly connected to one end of the connecting plate near the sliding frame. Each liquid storage box is filled with industrial hydraulic oil, and a rotating block is rotatably connected inside the liquid storage box. The outer wall of the rotating block slides through the inside of the liquid storage box.

[0010] As a further aspect of this solution, the outer wall of the rotating block is fixedly connected to multiple movable plates, and the outer wall of each movable plate is provided with multiple rectangular grooves. The end of the rotating block away from the liquid storage box is fixedly connected to a first abutting plate, and the end of the first abutting plate opposite to the connecting block is fixedly connected to multiple first locking teeth.

[0011] As a further aspect of this solution, the emergency stop mechanism includes a first circular plate, which is fixedly connected to the outer wall of all the sliding columns, and a plurality of second circular plates are fixedly connected to one end of the sliding frame near the first circular plate.

[0012] As a further aspect of this solution, the second circular plate and the opposite end of the first circular plate are each fixedly connected with a plurality of second locking teeth.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When using this utility model tool, the liquid storage box is moved by an electric telescopic arm, causing the first and second abutment plates to engage with each other. The resistance generated by the rotation of the moving plate in industrial hydraulic oil creates dynamic damping on the rolling wheel, effectively solving the problem of accelerated sliding of the thin-walled box due to the tilt of the sliding frame and its excessive weight. This design requires no continuous manual intervention and can adaptively adjust the resistance of the rolling wheel according to the sliding speed of the box. This avoids the risk of loss of control of the box caused by improper manual control and can adapt to the transportation needs under different weights and tilt conditions, significantly improving the stability of the thin-walled box during transportation and reducing damage such as scratches and deformation caused by excessive speed.

[0015] 2. When using this tool, if the thin-walled box moves too rapidly for the operator to control, pressing the emergency stop button will drive the electric telescopic arm to retract further. This causes the second abutment plate to push the first circular plate against the second circular plate, and the limiting action of the second locking tooth directly locks the rotating rod, achieving emergency braking of the box and quickly cutting off dangerous conditions, minimizing the incidence of collisions, falls, and other safety accidents. After use, simply controlling the second locking tooth to reset, along with the spring to disengage the relevant components, completes the equipment reset. The entire operation is simple and convenient, requiring no complex disassembly or maintenance, effectively improving equipment reuse efficiency and reducing subsequent usage costs.

Detailed Implementation

[0021] 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.

[0022] Example 1: Please refer to Figures 1-3 As shown in the embodiment of this utility model, a thin-walled box transport tool includes a sliding frame 1. The outer wall of the sliding frame 1 is rotatably connected to multiple rolling wheels 5 via a rotating shaft, and the outer wall of the sliding frame 1 is also rotatably connected to multiple rotating rods 6 via a rotating shaft. The outer wall of each rotating rod 6 is fixedly connected to the interior of two adjacent rolling wheels 5. The bottom of the sliding frame 1 is rotatably connected to two electrically retractable legs 2 via a rotating shaft, and the bottom of the sliding frame 1 is also rotatably connected to two mounting legs 3. The two mounting legs 3 are fixedly connected to a stop frame 4 by bolts. Specifically, in use, it is only necessary to rotate and fix the electrically retractable legs 2 to the ground in contact with them using nuts. The two electrically retractable legs 2 extend simultaneously to lift the sliding frame 1, causing the sliding frame 1 to tilt. The stop frame 4 can enhance the stability of the two mounting legs 3. A deceleration mechanism 101 is installed between the outer wall of each rotating rod 6 and the sliding frame 1, and an emergency stop mechanism 201 is also fixedly installed between the rotating rod 6 and the sliding frame 1.

[0023] Example 2: Please refer to Figures 1-4 As shown, the deceleration mechanism 101 includes a connecting block 16, which is fixedly connected to the outer wall of the rotating rod 6 by bolts. Multiple sliding columns 19 with reset function are slidably connected inside the connecting block 16. The multiple sliding columns 19 are circumferentially distributed inside the connecting block 16. Specifically, multiple sliding openings are opened inside the connecting block 16, and the multiple sliding openings are circumferentially distributed inside the connecting block 16. Each sliding column 19 is slidably connected to the inner wall of a nearby sliding opening. A cooperating spring 20 is fixedly connected between the sliding column 19 and the connecting block 16, and the cooperating spring 20 is sleeved on the outer wall of the sliding column 19.

[0024] Two electric telescopic arms 22 are fixedly connected to the outer wall of the sliding frame 1. A connecting plate 7 is fixedly connected between the two electric telescopic arms 22. Multiple liquid storage boxes 10 are fixedly connected to the end of the connecting plate 7 near the sliding frame 1. Each liquid storage box 10 is filled with industrial hydraulic oil. The industrial hydraulic oil is in a liquid viscous state. A rotating block 12 is rotatably connected to the inside of the liquid storage box 10 through a rotating shaft. The outer wall of the rotating block 12 slides through the inside of the liquid storage box 10. Multiple moving plates 11 are fixedly connected to the outer wall of the rotating block 12. The multiple moving plates 11 are circumferentially distributed on the outer wall of the rotating block 12. Multiple rectangular grooves are opened on the outer wall of each moving plate 11. A first abutting plate 13 is fixedly connected to the end of the rotating block 12 away from the liquid storage box 10. Multiple first locking teeth 15 are fixedly connected to the end of the first abutting plate 13 opposite to the connecting block 16. The multiple first locking teeth 15 are circumferentially distributed on the outer walls of the first abutting plate 13 and the second abutting plate 14.

[0025] Specifically, when the rotating block 12 rotates, it will synchronously drive all the moving plates 11 to move. The moving plates 11 rotate along the internal cavity of the liquid storage box 10. Since the liquid storage box 10 is filled with industrial hydraulic oil, the hydraulic oil needs to flow through the rectangular groove opened on its outer wall during the movement of the moving plate 11. The flow of hydraulic oil in the rectangular groove will generate damping force, thereby slowing down the moving speed of the moving plate 11 and finally achieving the speed reduction effect.

[0026] The emergency stop mechanism 201 includes a first circular plate 17, which is fixedly connected to the outer wall of all the sliding columns 19. A plurality of second circular plates 18 are fixedly connected to one end of the sliding frame 1 near the first circular plate 17. A plurality of second locking teeth 21 are fixedly connected to the opposite end of the second circular plate 18 and the first circular plate 17. The plurality of second locking teeth 21 are circumferentially distributed on the outer wall of the second circular plate 18 and the second locking teeth 21.

[0027] The working principle of this utility model is as follows:

[0028] When using this utility model, the electric retractable leg 2 is fixed to the ground in contact with it by a nut. At this time, the thin-walled box is placed on the upper end of the roller 5 and pushed to slide on the outer wall of the roller 5. If the electric retractable leg 2 causes the sliding frame 1 to tilt as a whole, the thin-walled box will slide faster due to gravity. If the overall weight of the thin-walled box is too large, it will cause the sliding speed to be too fast and it will be difficult for the operator to control it.

[0029] At this time, the two electric telescopic arms 22 are activated to retract. The electric telescopic arms 22 drive the connecting plate 7 to move towards the sliding frame 1. The connecting plate 7 will drive the liquid storage box 10 to move. The liquid storage box 10 will drive the first abutting plate 13 and the second abutting plate 14 to abut against each other. At this time, the first locking teeth 15 between the two will engage with each other. When the thin-walled box moves on the outer wall of the rolling wheel 5, the rolling wheel 5 will rotate. The rolling wheel 5 will drive the rotating rod 6 to rotate. The rotating rod 6 will drive the second abutting plate 14 and the first abutting plate 13 to rotate. The first abutting plate 13 will drive the rotating block 12 and the moving plate 11 to rotate. Since the moving plate 11 will reduce the rotation speed due to the resistance generated by the industrial hydraulic oil, the speed reduction effect of the thin-walled box is achieved.

[0030] If the thin-walled box moves rapidly and the staff cannot control it, press the emergency stop button 8. At this time, the two electric telescopic arms 22 will retract and drive the connecting plate 7 to move. The connecting plate 7 will drive the liquid storage box 10 to move. The liquid storage box 10 will drive the rotating block 12 and the first abutting plate 13 to move together. Then the first abutting plate 13 will push the second abutting plate 14. At this time, the second abutting plate 14 will push the first circular plate 17 through the sliding column 19. When the first circular plate 17 and the second circular plate 18 abut, the second locking tooth 21 will create a limit lock to prevent the rotating rod 6 from rotating, which can achieve an emergency stop effect for the thin-walled box.

[0031] After use, activate the two electric telescopic arms 22 to reset the connecting plate 7. At this time, the connecting plate 7 will reset all the liquid storage boxes 10. The first abutment plate 13 will disengage from the outer wall of the second abutment plate 14. Then, with the help of the spring 20, the first circular plate 17 will disengage from the outer wall of the second circular plate 18, and it can be used again.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
