Technical Field

[0001] This invention relates to the field of lifting motor technology, and specifically to a transmission mechanism for a lifting motor. Background Technology

[0002] The lifting motor is the main power source of lifting equipment, converting the motor's rotational motion into the linear lifting motion of the terminal unit through its transmission mechanism. Common transmission mechanisms for lifting motors include gears, lead screws, chains, belts, and hydraulic transmissions.

[0003] Existing technologies, such as CN201480026950.X, disclose a transmission system for a lifting device, which adjusts the output speed of the motor through a reducer and then completes the lifting operation of the cable end by winding the cable through a drum. However, the transmission mechanism of this device is an integrated structure. After a failure, it is necessary to disassemble each part of the transmission mechanism one by one, which is complicated and not conducive to the quick repair and replacement of the lifting motor and transmission mechanism.

[0004] Therefore, it is necessary to provide a modular design for the lifting motor transmission mechanism, which allows for quick assembly and disassembly of the entire device based on faulty modules, thereby improving maintenance efficiency and reducing downtime of the lifting device. Summary of the Invention

[0005] The purpose of this invention is to provide a transmission mechanism for a lifting motor. By modularly designing the transmission mechanism, the transmission mechanism is divided into two components that can be quickly disassembled, so as to achieve the purpose of quickly replacing faulty modules and improving maintenance efficiency.

The housing is provided with a connecting seat, which is detachably connected to the motor mounting seat by screws.

[0009] Preferably, the mounting plate is provided with a transmission component placement seat; The second transmission assembly further includes a second transmission shaft and a first bevel gear.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] This invention discloses a transmission mechanism for a lifting motor, such as... Figure 1 As shown, the system includes a base 100, a drum fixing frame 200 on the base 100, a drum 210 on the drum fixing frame 200, a mounting plate 220 on the drum fixing frame 200, a motor mounting seat 300 on the mounting plate 220, a motor 310 and a first transmission assembly 320 respectively on both sides of the motor mounting seat 300, and a second transmission assembly 230 on the same side of the drum fixing frame 200 as the first transmission assembly 320. Figure 2 As shown, the mounting plate 220 and the motor mounting base 300 are provided with corresponding screw holes 400, and the motor mounting base 300 and the mounting plate 220 are detachably connected by screws 500.

[0026] like Figure 2-4 As shown, the first transmission assembly 320 is a worm gear transmission box 321, which is equipped with an output gear 322. The second transmission assembly 230 is equipped with an input gear 231 that meshes with the output gear 322. Both the output gear 322 and the input gear 231 are spur gears, and their axes are perpendicular to the mounting plate 220. Figure 2 As shown, when it is necessary to disassemble the motor 310 for maintenance, the screw 500 can be removed directly, and then pulled out laterally along the gear axis of the input gear 231 and the output gear 322, so that the motor mounting base 300, the motor 310 and the first transmission assembly 320 can be taken out at the same time.

[0027] like Figure 3-6 As shown, the motor mounting base 300 has a through hole 330, through which the output shaft of the motor 310 passes and connects to the worm gear transmission box 321. The worm gear transmission box 321 includes a housing, inside which a worm gear 323 and a worm 324 are fitted together. The worm 324 is connected to the output shaft of the motor 310 via a coupling 325. A bearing 326 is provided on the outside of the coupling 325. The output gear 322 is located outside the housing and rotates synchronously with the worm gear 323 via a first transmission shaft 327. A connecting seat 328 is provided on the housing and is detachably connected to the motor mounting base 300 by screws 500. Figure 4 As shown, after removing the motor mounting bracket 300, the screws 500 can be further removed, and then the motor mounting bracket 300 can be separated from the worm gear transmission box 321.

[0028] like Figure 7 As shown, the mounting plate 220 is provided with a transmission component placement seat 240. The second transmission assembly 230 also includes a second transmission shaft 232 and a first bevel gear 233. The second transmission shaft 232 passes through the transmission component placement seat 240, and the input gear 231 and the first bevel gear 233 are respectively located at both ends of the second transmission shaft 232 and rotate synchronously. The drum 210 is provided with a main rotating shaft 211, and the end of the main rotating shaft 211 is provided with a second bevel gear 212 that cooperates with the first bevel gear 233.

[0029] like Figure 2 , 6 As shown in Figure 7, the transmission component placement seat 240 is also provided with a bearing support and fixing seat 241. The first transmission shaft 327 has a protrusion 329 on the outside of the output gear 322, and inserts into the bearing support and fixing seat 241 through the protrusion 329. The bearing support and fixing seat 241 can support the first transmission shaft 327, and the protrusion 329 and the bearing support and fixing seat 241 are plug-in structure to facilitate quick disassembly of the motor mounting seat 300.

[0030] A prism portion 213 is provided on the main rotating shaft 211, and the drum 210 is sleeved on the prism portion 213 and slidably connected to it. A cable guide 600 is provided on the base 100, located in the middle section of the drum fixing frame 200. The cable guide 600 includes a support plate 610 and guide wheels 620 located on the top of the support plate 610. There are two guide wheels 620 arranged opposite each other, and each guide wheel 620 has a groove 621 for the cable 700 to pass through. Figure 7 As shown, the two guide wheels 620 can stabilize the cable 700 and prevent the cable 700 from shaking during the lifting process, which would prevent the cable 700 from being evenly wound on the drum 210.

[0031] like Figure 8 As shown, a cable guide wheel 630 is located below the guide wheel 620. The cable guide wheel 630 has a guide groove 631, and the drum 210 has a cable groove 214 that mates with the guide groove 631. The drum fixing frame 200 has a gear transmission pair 250 and a third transmission shaft 260. The main rotating shaft 211 drives the third transmission shaft 260 to rotate via the gear transmission pair 250, and the cable guide wheel 630 is located at the end of the third transmission shaft 260. When the motor 310 drives the drum 210 to rotate via the first transmission assembly 320 and the second transmission assembly 230, the main rotating shaft 211 rotates synchronously and drives the third transmission shaft 260 and the cable guide wheel 630 to rotate via the gear transmission pair 250. The cable guide wheel 630 guides the cable 700 into the cable groove 214, ensuring that the cable 700 is evenly distributed on the drum 210.

[0032] This invention employs a modular structure, dividing the transmission structure into a first transmission component 320 and a second transmission component 230. The first transmission component 320 and the second transmission component 230 use a plug-in transmission connection structure, allowing for quick separation during disassembly, thereby improving the efficiency of disassembly and maintenance and facilitating disassembly and repair operations. Simultaneously, the motor 310 and the first transmission component 320 also adopt a direct-insertion structure, further improving the ease of disassembly of the motor 310.

[0033] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
