[0011] As a further description of the above technical solution:
[0012] The bottom of the lifting box is fixedly connected to two fixing blocks. Each fixing block has a slot at its bottom.

[0020] The fixing component includes a hydraulic rod, which is fixedly installed on the top of the support plate. A rubber plate is provided at the bottom of the support plate, and the top of the rubber plate is fixedly connected to the telescopic end of the hydraulic rod.

[0030] 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.
[0031] Reference Figure 1-4 This utility model provides a material lifting device with a limiting structure: it includes two support plates 1, which are fixedly connected to each other. A support frame 2 is fixedly connected to the top of each support plate 1. A rotating shaft 3 is rotatably connected between opposite sides of the two support frames 2. A lifting component is mounted on the rotating shaft 3. Limiting grooves 4 are formed on each of the two support frames 2. A limiting frame 5 is slidably connected inside the two limiting grooves 4. An annular plate 6 is fixedly connected to the top of the limiting frame 5. A toothed ring 7 is rotatably connected to the annular plate 6. A placement ring 8 is fixedly connected to the top of the toothed ring 7. Several sets of positioning blocks 9 are fixedly connected to the top of the placement ring 8, with two blocks in each set. A fixing groove 15 is formed on each positioning block 9. The placement ring 8 is provided with... The device includes a lifting box 10, a driving assembly on a limiting frame 5, and two casters 11 fixedly connected to the bottom of a support plate 1. A fixing assembly is also provided on the support plate 1. Through the arrangement of the support frame 2, limiting groove 4, limiting frame 5, lifting box 10, and winding roller 13, the lifting box 10 can be easily adjusted to the desired position during use by rotation. This solves the problem of inconvenience and reduced efficiency in adjusting the material lifting angle when the receiving position of the material changes. Previously, changing the material lifting angle required stopping the device and readjusting the entire device, making the adjustment process inconvenient and affecting the efficiency of material angle adjustment. Therefore, the device's applicability is improved.
[0032] The lifting assembly includes a motor 12 and a take-up roller 13. The motor 12 is fixedly installed on one side of one of the support frames 2. The output end of the motor 12 is fixedly connected to one end of the rotating shaft 3. The take-up roller 13 is fixedly sleeved on the outer surface of the rotating shaft 3. A lifting rope 14 is fixedly wound on the outer surface of the take-up roller 13. The other end of the lifting rope 14 is fixedly connected to the top of the limiting frame 5. By setting up the lifting assembly, the lifting rope 14 can be wound up, thereby driving the placement plate and the lifting box 10 to move upward synchronously, thereby lifting the material.
[0033] The bottom of the lifting box 10 is fixedly connected to two fixing blocks 16. Each fixing block 16 has a slot 17 at its bottom. A spring 18 is fixedly connected to one side of the fixing block 16, and a fixing rod 19 is fixedly connected to the other end of the spring 18. One end of the fixing rod 19 extends into the slot 17. The fixing rod 19 is adapted to the fixing groove 15. Through the coordinated use of the positioning block 9, fixing groove 15, fixing block 16, slot 17, spring 18 and fixing rod 19, the lifting box 10 can be easily disassembled, cleaned and installed. This allows for easy increase or decrease in the number of uses, thereby increasing the amount of material lifted in a single operation when lifting a large amount of material, and thus improving the practicality of the device.
[0034] The drive assembly includes a second motor 20, which is mounted on the limit frame 5. A gear 21 is fixedly connected to the output end of the second motor 20, and the gear 21 meshes with the gear ring 7. The second motor 20 is fixedly mounted on the top of the limit frame 5 via a bracket 22. Through the configuration of the drive assembly, the gear ring 7 can be driven to rotate. After the gear ring 7 drives the placement plate to rotate, it can drive the lifting box 10 to rotate, thereby adjusting its position.
[0035] The fixing component includes a hydraulic rod 23, which is fixedly installed on the top of the support plate 1. A rubber plate 24 is provided at the bottom of the support plate 1. The top of the rubber plate 24 is fixedly connected to the telescopic end of the hydraulic rod 23. By setting the fixing component, when the rubber plate 24 moves down and abuts against the ground, the contact surface with the ground is increased to improve the friction, thereby improving the stability of the device during use.
[0036] Working principle: When in use, start the hydraulic rod 23 to extend its telescopic end, which drives the corresponding rubber plate 24 to move down and come into contact with the ground, increasing the contact area with the ground and improving the friction, thereby improving the stability of the device during use. Then, the material to be lifted can be directly put into the lifting box 10, and start the motor 12 to drive the rotating shaft 3 and the winding roller 13 to rotate and wind up the lifting rope 14. Under the guiding and limiting action of the limiting groove 4, the lifting rope 14 drives the limiting frame 5, the placement plate and the lifting box 10 and other structures to move up synchronously, which can carry out the lifting work of materials.
[0037] When the material receiving position changes during use, requiring a change in the material lifting angle, motor 20 is activated, driving gear 21 to rotate. Gear 21 drives gear ring 7, which in turn rotates synchronously. Gear ring 7 drives the placement plate and lifting box 10 to rotate synchronously, allowing adjustment of the horizontal position of lifting box 10. This enables the material to be received at different positions. When more material needs to be lifted, the number of lifting boxes 10 can be increased. A new lifting box 10 is taken out, its two bottom fixing blocks 16 are aligned with the corresponding two positioning blocks 9, and the lifting box 10 is lowered. This causes the corresponding fixing blocks 16 to move downwards, moving the corresponding positioning blocks 9 into the corresponding slots 17. The inclined surface of the corresponding fixing rod 19 is then pressed, causing it to move away from the slot 17 and stretching the corresponding spring 18 until, under the action of elasticity, the fixing rod 19 returns to its original position and inserts into the corresponding fixing groove 15, thus increasing the amount of material lifted in a single operation.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
