DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1 to 5 shown, the present utility model provides a material lifting platform for construction sites, including a chassis 1, a top frame 2, and the top frame 2 is fixedly arranged above the chassis 1;

[0022] A sliding mechanism is fixedly installed on the side of the chassis 1, and a polishing mechanism is movably installed above the sliding mechanism;

[0023] The grinding mechanism includes a sandpaper protection box 7 movably arranged above the sliding mechanism. A driving wheel 8 is rotatably installed on one side of the sandpaper protection box 7. There are two driving wheels 8, and both are rotatably arranged on the side of the sandpaper protection box 7. A belt 12 is drivingly connected between the two driving wheels 8. A clamping column 11 is fixedly installed on the side of the sandpaper protection box 7, and the bottom of the clamping column 11 is fixedly installed at the bottom of the driving wheel 8. A limiting column 10 is fixedly installed on the side of the sandpaper protection box 7. The limiting column 10 is located right below the driving wheel 8. The number of the limiting columns 10 is six. A sandpaper 9 is movably sleeved above the driving wheel 8 and the limiting column 10. One side of the sandpaper 9 is in close contact with the sliding mechanism. The clamping column 11 is located on the side of the sandpaper 9. A helical gear 6 is fixedly installed on the side of the sliding mechanism. A gear 26 is fixedly installed at the bottom of the driving wheel 8. The helical gear 6 meshes with the gear 26.

[0024] When the staff uses it, the staff first starts the driving mechanism. After the driving mechanism is started, it will drive the material box 24 to move up and down. When the material box 24 moves up and down, it will drive the sliding box 4 and the sandpaper protection box 7 to move up and down. The up and down movement of the sliding box 4 and the sandpaper protection box 7 will cause friction between the roller 5 and the slide rail 3. The friction drives the roller 5 to rotate. When the roller 5 rotates, it will drive the rotation of the helical gear 6. When the helical gear 6 rotates, since the helical gear 6 and the sandpaper 9 mesh with each other, the rotation of the helical gear 6 will drive the rotation of the sandpaper 9. When the sandpaper 9 rotates, it will drive the rotation of the driving wheel 8. When the driving wheel 8 rotates, it will drive the movement of the sandpaper 9. The movement of the sandpaper 9 rubs on the surface of the slide rail 3.

[0025] The rotation of the roller 5 drives the rotation of the helical gear 6, thereby driving the rotation of the driving wheel 8 through the rotation of the helical gear 6, and then driving the movement of the sandpaper 9 through the rotation of the driving wheel 8, so as to polish the surface of the slide rail 3. Compared with the traditional device, by polishing the surface of the slide rail 3, this device can prevent the surface of the slide rail 3 from rusting, which may cause blockage when the roller 5 moves above the slide rail 3. At the same time, through polishing, the damage of the slide rail 3 is reduced.

[0026] Wherein, a fixing plate 13 is fixedly installed at the bottom of the sandpaper protection box 7. A spring 14 is fixedly installed at the bottom of the fixing plate 13. A fixing ring 15 is fixedly installed at the bottom of the spring 14. A limiting abutting column 16 is fixedly sleeved above the fixing ring 15. One end of the limiting abutting column 16 penetrates through the upper and lower sides of the fixing plate 13. A clamping plate 17 is movably installed on the side of the sandpaper protection box 7. The clamping plate 17 is movably connected to the sandpaper 9.

[0027] When in use by the staff, when the staff first installs the sandpaper 9 above the device, one end of the spring 14 will move downward. When one end of the spring 14 moves downward, it will drive the fixing ring 15 to move downward. When the fixing ring 15 moves downward, it will drive the limiting abutting post 16 to move downward. When the limiting abutting post 16 moves downward, the bottom of the limiting abutting post 16 will move downward. When the bottom of the limiting abutting post 16 contacts the clamping plate 17, it will drive the clamping plate 17 to move downward, thereby pressing against the sandpaper 9 through the clamping plate 17.

[0028] Through the cooperation between the spring 14 and the fixing ring 15, the clamping plate 17 can be moved downward. By the downward movement of the clamping plate 17, the movement and position of the sandpaper 9 are restricted. Compared with traditional devices, this device presses against the sandpaper 9 through the elasticity of the spring 14, thereby preventing one side of the sandpaper 9 from failing to be in close contact with the slide rail 3, and thus failing to polish the slide rail 3. Through close fitting, the polishing effect on the slide rail 3 can be enhanced.

[0029] Among them, the sliding mechanism includes a slide rail 3 fixedly arranged on the side of the chassis 1. A roller 5 is movably installed on the side, a sliding box 4 is rotatably installed on the side of the roller 5, the upper part of the sliding box 4 is fixedly connected to the sandpaper protection box 7, a bevel gear 6 is fixedly connected to the side of the roller 5, and a material box 24 is fixedly installed on the side of the sliding box 4.

[0030] By the roller 5 rolling on the side of the slide rail 3, the friction between the roller 5 and the slide rail 3 is reduced, and at the same time, the phenomenon of the material box 24 shaking during movement can be avoided.

[0031] Among them, a motor protection box 18 is fixedly installed on the top of the top frame 2. A double-shaft motor 25 is fixedly installed on one side inside the motor protection box 18. The top end of the output shaft of the double-shaft motor 25 is fixedly installed with a transmission frame 19. One end of the transmission frame 19 movably penetrates the side of the motor protection box 18. A fixing frame 20 is fixedly installed above the chassis 1. A winding wheel 21 is rotatably installed above the fixing frame 20. One end of the transmission frame 19 penetrates one side of the fixing frame 20 and is fixedly connected to the winding wheel 21. A connecting line 22 is movably sleeved above the winding wheel 21. One end of the connecting line 22 penetrates the upper and lower sides of the top frame 2 and is fixedly installed with a connecting block 23. The bottom of the connecting block 23 is fixedly connected to the material box 24.

[0032] By starting the double-shaft motor 25, when the double-shaft motor 25 starts, it will drive the rotation of the transmission frame 19. By the rotation of the transmission frame 19, it will drive the rotation of the winding wheel 21. When the winding wheel 21 rotates, one end of the connecting line 22 will move up and down, thereby driving the up and down movement of the material box 24.

[0033] Among them, an opening and closing door 27 is hingedly installed on the front of the material box 24, and the hinge is located at the bottom of the side of the material box 24.

[0034] The material inside the material box 24 can be taken out by the biaxial motor 25, which facilitates taking out the material inside the material box 24.

[0035] Wherein, sliding mechanisms and grinding mechanisms are arranged on both sides of the slide rail 3, and there are four rollers 5 in each group of sliding mechanisms, which are evenly distributed on the side surface of the slide box 4.

[0036] Through the grinding mechanisms on both sides of the slide rail 3, both sides of the slide rail 3 are ground.

[0037] The working principle and usage process of the present utility model:

[0038] When the staff uses it, the staff first starts the driving mechanism. After the driving mechanism is started, it will drive the material box 24 to move up and down. When the material box 24 moves up and down, it will drive the slide box 4 and the sandpaper protection box 7 to move up and down. Through the up and down movement of the slide box 4 and the sandpaper protection box 7, friction will be generated between the roller 5 and the slide rail 3. Through the friction, the roller 5 will be driven to rotate. When the roller 5 rotates, it will drive the bevel gear 6 to rotate. When the bevel gear 6 rotates, since the bevel gear 6 and the sandpaper 9 are meshed with each other, the rotation of the bevel gear 6 will drive the rotation of the sandpaper 9. When the sandpaper 9 rotates, it will drive the rotation of the transmission wheel 8. When the transmission wheel 8 rotates, it will drive the movement of the sandpaper 9. Through the movement of the sandpaper 9, friction is carried out on the surface of the slide rail 3.

[0039] When the staff uses it, when the staff first installs the sandpaper 9 above the device, one end of the spring 14 will move downward. When one end of the spring 14 moves downward, it will drive the fixing ring 15 to move downward. When the fixing ring 15 moves downward, it will drive the limiting abutting post 16 to move downward. When the limiting abutting post 16 moves downward, the bottom of the limiting abutting post 16 will move downward. When the bottom of the limiting abutting post 16 contacts the clamping plate 17, it will drive the clamping plate 17 to move downward, thereby pressing the sandpaper 9 through the clamping plate 17.
