[0001] This utility model relates to the field of roller lift technology, specifically a roller lift with anti-slip rollers. Background Technology

[0002] During the sheet material processing, a lifting platform is needed to transport the sheets. In order to connect with the front and rear roller conveyor lines, the lifting platform also needs to have rollers. Therefore, roller lifts are indispensable.

[0003] A search revealed a rotary drum lift with publication number (CN221070837U), comprising a U-shaped plate; a set of rotating cylinders disposed within the U-shaped plate and respectively connected to the U-shaped plate by bearings; a motor disposed on one side of one end of the U-shaped plate, the motor being connected to the U-shaped plate via a motor bracket, and the output shaft of the motor being connected to one of the rotating cylinders; symmetrical upper U-plates disposed at the lower center of the U-shaped plate and connected to the U-shaped plate; a base plate disposed below the U-shaped plate, the upper center of the base plate being connected to symmetrical lower U-plates; symmetrical upper connecting rods disposed on the lower side of the U-shaped plate and respectively rotatably connected to the corresponding upper U-plates; and symmetrical lower connecting rods disposed on one side of the corresponding upper connecting rod and respectively rotatably connected to the corresponding lower U-plates.

[0004] The implementation of this technical solution has at least the following drawbacks: While this utility model can solve the problem of equipment tipping over due to the center of gravity shifting to one side when transporting plates with a rotating drum, it cannot adjust the center of gravity in real time during the rotation of the roller conveyor frame, nor can it adapt to the weight of the material on the roller conveyor frame. Therefore, improvements are urgently needed. Thus, we propose a roller lift with anti-slip rollers. Utility Model Content

[0005] The purpose of this utility model is to provide a roller lift with anti-slip rollers, which solves the problems mentioned in the background art, which cannot adjust the center of gravity in real time during the rotation of the roller conveyor frame, and cannot make adaptive adjustments according to the weight of the material on the roller conveyor frame.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a roller lift with anti-slip rollers, comprising a base, a fixed frame at the upper end of the base, multiple roller bodies arranged inside the fixed frame, hydraulic cylinders fixedly installed on both sides of the base, and four hydraulic cylinders in total, a support frame installed at the output end of each hydraulic cylinder, a rotating seat fixedly installed at the upper end of the support frame, a dual-axis servo motor fixedly installed at the lower middle part of the support frame, the upper output end of the dual-axis servo motor being rotatably connected to the rotating seat, a spline rod fixedly installed at the lower output end of the dual-axis servo motor, a fixed plate rotatably installed at the lower middle part of the base, a spline groove opened on one side of the fixed plate, and a receiving box welded to the other side of the upper end of the fixed plate, with a counterweight placed inside the receiving box.

[0007] By adopting the above technical solution, the spline rod can drive the fixed plate to rotate, which in turn drives the counterweight block in the receiving box on one side of the fixed plate to rotate accordingly. This causes the counterweight block in the receiving box to rotate relative to the material at one end of the fixed frame, thereby balancing the center of gravity force during the rotation of the fixed frame. This achieves real-time adjustment of the center of gravity during the rotation of the roller fixed frame, further improving the stability of the fixed frame rotation. Furthermore, the receiving box on the fixed plate allows for adjustment of the number of counterweight blocks, enabling adaptive adjustment based on the weight of the material on the roller fixed frame, further improving the balance effect of the device's center of gravity. Additionally, the ball bearings on the fixed plate ensure the smooth rotation of the fixed plate and the base.

[0008] Optionally, the dimensions of the spline rod are adapted to the dimensions of the spline groove, and the spline rod and the spline groove are movably connected.

[0009] By adopting the above technical solution, through the cooperation of the spline rod and the spline groove, the spline rod can be separated from the fixed plate when the hydraulic cylinder drives the fixed frame to rise and fall, so as not to affect the rising and falling of the rollers on the fixed frame.

[0010] Optionally, the upper end of the rotating seat is detachably connected to the lower end of the fixed frame.

[0011] By adopting the above technical solution and setting the rotating seat, it is convenient to drive the roller on the fixed frame to rotate.

[0012] Optionally, the roller bodies are equidistantly distributed, and the outer side wall of each roller body is bonded with an anti-slip sleeve.

[0013] By adopting the above technical solution and setting the anti-slip sleeve, the anti-slip effect of the roller body can be improved.

[0014] Optionally, the length of the spline bar is greater than the length of the spline groove.

[0015] By adopting the above technical solution, it is easy to ensure that the spline rod can drive the fixed plate to rotate.

[0016] Optionally, a plurality of ball bearings are rotatably mounted on the lower end of the fixing plate, and the ball bearings are in contact with the upper end of the base.

[0017] By adopting the above technical solution and using the ball bearings, the smoothness of the fixed plate rotation is ensured.

[0018] Optionally, the base has positioning holes around its lower end, and there are four positioning holes.

[0019] By adopting the above technical solution and setting the positioning holes, the base can be positioned and limited.

[0020] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0021] The technical solution of this application, through the design of a base, fixed frame, roller body, hydraulic cylinder, dual-axis servo motor, spline rod, ball bearings, and spline groove, enables the spline rod to drive the fixed plate to rotate, thereby causing the counterweight block in the receiving box on one side of the fixed plate to rotate accordingly. This allows the counterweight block in the receiving box to rotate relative to the material at one end of the fixed frame, thus balancing the center of gravity force during the rotation of the fixed frame. This achieves real-time adjustment of the center of gravity during the rotation of the roller fixed frame, further improving the stability of the fixed frame rotation. Furthermore, the receiving box on the fixed plate allows for adjustment of the number of counterweight blocks, enabling adaptive adjustment based on the weight of the material on the roller fixed frame, further improving the balance effect of the device's center of gravity. Finally, the ball bearings on the fixed plate ensure the smooth rotation of the fixed plate and the base. Attached Figure Description

[0027] Please see Figure 1-3 This utility model provides a technical solution: a roller lift with anti-slip rollers, including a base 1, a fixed frame 11 at the upper end of the base 1, multiple roller bodies 13 arranged inside the fixed frame 11, hydraulic cylinders 2 fixedly installed on both sides of the base 1, and four hydraulic cylinders 2 are configured. A support frame 21 is installed at the output end of the hydraulic cylinder 2, a rotating seat 22 is fixedly installed at the upper end of the support frame 21, a dual-axis servo motor 23 is fixedly installed at the lower middle part of the support frame 21, the upper output end of the dual-axis servo motor 23 is rotatably connected to the rotating seat 22, a spline rod 24 is fixedly installed at the lower output end of the dual-axis servo motor 23, and a fixed plate 3 is rotatably installed at the lower middle part of the base 1. A spline groove 6 is opened on one side of the fixed plate 3. A receiving box 4 is welded to the other side of the upper end of the fixed plate 3. A counterweight is placed in the inner cavity of the receiving box 4. The roller bodies 13 are evenly distributed, and an anti-slip sleeve is glued to the outer wall of the roller body 13. The anti-slip sleeve improves the anti-slip effect of the roller body 13. The length of the spline rod 24 is greater than the length of the spline groove 6, which makes it easy to ensure that the spline rod 24 can drive the fixed plate 3 to rotate. Multiple balls 5 are rolled on the lower end of the fixed plate 3, and the balls 5 are in contact with the upper end of the base 1. The balls 5 ensure the smooth rotation of the fixed plate 3. Positioning holes 12 are opened around the lower end of the base 1, and there are four positioning holes 12. The positioning holes 12 can be used to position and limit the base 1.

[0028] The dimensions of the spline rod 24 are adapted to the dimensions of the spline groove 6, and the spline rod 24 and the spline groove 6 are movably connected. Through the cooperation between the spline rod 24 and the spline groove 6, the spline rod 24 can be separated from the fixed plate 3 when the hydraulic cylinder 2 drives the fixed frame 11 to rise and fall, so as not to affect the rising and falling of the roller on the fixed frame 11.

[0029] The upper end of the rotating seat 22 is detachably connected to the lower end of the fixed frame 11. The rotating seat 22 facilitates the rotation of the rollers on the fixed frame 11.

[0030] During adjustment, the dual-axis servo motor 23 is first turned on, which drives the upper rotating seat 22 to rotate. At the same time, the dual-axis servo motor 23 drives the spline rod 24 to rotate, which in turn drives the fixed plate 3 to rotate. This causes the counterweight in the receiving box 4 on one side of the fixed plate 3 to rotate as well, so that the counterweight in the receiving box 4 rotates relative to the material at one end of the fixed frame 11. This balances the center of gravity of the fixed frame 11 during rotation, thereby achieving real-time adjustment of the center of gravity during the rotation of the roller fixed frame 11. This further improves the stability of the rotation of the fixed frame 11. Moreover, the number of counterweights can be adjusted by the receiving box 4 on the fixed plate 3, which can be adapted to the weight of the material on the roller fixed frame 11, further improving the balance of the device's center of gravity. At the same time, the ball bearings 5 ​​on the fixed plate 3 ensure the smooth rotation of the fixed plate 3 and the base 1.
