Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of lifting devices, and particularly relates to a roller type elevator with low wear. Background Technique
[0002] An elevator is a mechanical device for vertically transporting objects. An elevator generally includes a column, a lifting platform, and a winch. A sling is wound around the winch, and one end of the sling is fixedly connected to the lifting platform. The lifting platform moves up and down under the drive of the winch, so as to transport an object from a low place to a high place.
[0003] Most of the existing elevators use guide shoes or nylon sliders as the guiding mechanism for the up and down movement of the lifting platform. During the lifting process, the friction between the guide shoes or nylon sliders and the elevator frame is relatively large, which will cause unnecessary wear and also reduce the mechanical transmission efficiency. Therefore, it is urgent to design a roller type elevator with low wear to solve the above problems. Content of the Utility Model

[0010] Furthermore, the feeding mechanism includes a feeding frame. At the top of the feeding frame, there are several first rollers. At the same end of several first rollers, two first driving sprockets are fixed respectively. At the inner bottom of the feeding frame, a first motor is fixed. Between adjacent first rollers and between the first motor and the first roller at any end of the feeding frame, they are connected by driving chains.
[0011] Moreover, the feeding frame is flush with the top of the lifting frame at the lowest position. Guide rails are fixed on both sides of the top of the feeding frame and the lifting frame.
[0012] Moreover, a second motor is fixed inside the lifting frame. Between the second motor and the second roller at any end of the lifting frame and between adjacent second rollers, they are connected by driving chains.

[0025] frame body 100;
[0026] The feeding mechanism 200 is arranged on one side of the frame body 100;
[0027] The lifting mechanism 300 includes a lifting frame 301 arranged inside the frame body 100, a positioning sprocket one 302 arranged at the four corners of the bottom of the frame body 100, a motor three 303 and a transmission shaft 304 arranged at the top of the frame body 100. A plurality of rollers two 305 are arranged at the top of the lifting frame 301. Two transmission sprockets two 306 are fixed at the same end of the plurality of rollers two 305. A connecting block 307 and a guide wheel 308 are respectively arranged on both sides of the lifting frame 301. Two positioning sprockets two 309 are fixed at both ends of the transmission shaft 304. The positioning sprocket one 302 is connected with the positioning sprocket two 309 through a lifting chain 310. Both ends of the lifting chain 310 are fixedly connected with the top and bottom of the connecting block 307 respectively. The guide wheel 308 is in rolling connection with the guide rod 104 fixed on the inner side surface of the frame body 100.
[0028] In addition, the frame body 100 is a cuboid frame structure. The frame body 100 includes longitudinal rods 101, cross rods 102, reinforcing rods 103 and guide rods 104. A ladder 105 is fixed on one side of the frame body 100. Guardrails 106 are fixed on the outside of the ladder 105 and the top of the frame body 100, which is convenient for the staff to climb to the top of the frame body 100 safely and quickly to complete the installation or maintenance work.
[0029] Specifically, the feeding mechanism 200 includes a feeding frame 201. A plurality of rollers one 202 are arranged at the top of the feeding frame 201. Two transmission sprockets one 203 are fixed at the same end of the plurality of rollers one 202. A motor one 204 is fixed at the inner bottom of the feeding frame 201. The adjacent two rollers one 202 and between the motor one 204 and the roller one 202 at any end of the feeding frame 201 are connected through a transmission chain, which is convenient to transmit the power of the motor one 204 to each roller one 202, so that the goods can be smoothly conveyed on the feeding frame 201.
[0030] It is worth mentioning that the feeding frame 201 is flush with the top of the lifting frame 301 at the lowest position to ensure that the goods can be conveyed from the feeding frame 201 to the lifting frame 301. Guide rails 205 are fixed on both sides of the top of the feeding frame 201 and the lifting frame 301, which can play a guiding role for the goods and prevent the goods from shifting or even slipping during the conveying process.
[0031] Specifically, a second motor 311 is fixed inside the lifting frame 301. The second motor 311 is connected to the second roller 305 at any end of the lifting frame 301 and between adjacent second rollers 305 by drive chains, facilitating the transmission of the power of the second motor 311 to each second roller 305, enabling the adjustment of the position of the goods on the lifting frame 301 to be at the center of the lifting frame 301, facilitating the lifting of the goods together with the lifting frame 301, and having the power to send the goods outside the frame body 100 when lifted to the designated position.
[0032] It should be noted that there are two drive shafts 304 in total. The two drive shafts 304 are respectively arranged on both sides of the third motor 303. A third drive sprocket 312 is fixed at one end of each of the two drive shafts 304. The third motor 303 is connected to the two drive shafts 304 by drive chains respectively, facilitating the transmission of the power of the third motor 303 to the two drive shafts 304, thereby driving the second positioning sprocket 309 to rotate. The rotation of the second positioning sprocket 309 can drive the movement of the lifting chain 310, thereby driving the lifting frame 301 to complete the lifting. A protective cover 313 is provided at the connection between the third motor 303 and the drive shaft 304, which can prevent foreign objects from being involved and ensure the smooth progress of the lifting movement.
[0033] Specifically, it further includes a discharging mechanism 400. The discharging mechanism 400 includes a mounting frame 401 fixed on one side of the frame body 100. A number of third rollers 402 are arranged between the two mounting frames 401. The mounting frame 401 is flush with the top of the lifting frame 301 at the highest position, facilitating the conveyance of the lifted goods onto the discharging mechanism 400.
[0034] Working principle: When the low-wear roller type elevator is in use, first start Motor 1 (204). Motor 1 (204) drives the rotation of Roller 1 (202), and then drives the goods on the feeding frame (201) to move onto the lifting frame (301). Then start Motor 3 (303). Motor 3 (303) drives the rotation of the transmission shaft (304). The positioning sprocket 2 (309) on the transmission shaft (304) drives the lifting chain (310) to move, and then drives the lifting frame (301) to lift upward. During the lifting process of the lifting frame (301), the guide wheel (308) rolls along the guide rod (104). When the lifting frame (301) is lifted to the specified height, start Motor 2 (311). Motor 2 (311) drives the rotation of Roller 2 (305), and then drives the goods on the lifting frame (301) to move onto the discharging mechanism (400). The low-wear roller type elevator is advanced in design, compact in structure and convenient to use. By arranging guide wheels (308) on both sides of the lifting frame (301) and arranging guide rods (104) that fit the guide wheels (308) on the inner side of the frame body (100), when driving the lifting frame (301) to lift and lower through Motor 3 (303), positioning sprocket 1 (302), positioning sprocket 2 (309) and the lifting chain (310), the guide wheel (308) serves as a guiding device in the up and down direction. The friction between the guide wheel (308) and the guide rod (104) is rolling friction. Compared with the sliding friction of the guide shoe, the friction force is greatly reduced, which is beneficial to reducing wear, improving the mechanical transmission efficiency and enabling the equipment to operate smoothly at the same time.
[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
