Description

Technical Field

[0001] This utility model relates to the technical field of speed reducer maintenance devices, and in particular to a quick-release device for speed reducers. Background Technology

[0002] Traditional gear reducer disassembly and assembly relies on horizontal pulling tools and pry bars for manual prying, which suffers from high labor intensity, low efficiency, cumbersome operation, and easy damage to components. For example, when removing the gear reducer from the drive shaft, the horizontal puller is connected to the gear reducer's disassembly hole via a screw, and then the gear reducer is shaken up and down to loosen the hollow sleeve from the main shaft and find the limit of the swing. However, the gear reducer's disassembly hole is not a symmetrical structure; the two elongated holes of the horizontal puller are symmetrically arranged, resulting in uneven force during use, making it difficult for the hollow sleeve to loosen from the main shaft. The moment the gear reducer is detached from the main shaft, the pressure on the personnel supporting the gear reducer increases, which can easily lead to injury. Existing technologies such as lead screw and ball bearing pulling devices can reduce damage, but they rely on manual operation, and there is still a possibility of injury when the gear reducer is lowered.

The disc pulling unit and the speed reducer support unit are slidably mounted on the platform support unit. That is, the platform support unit is used to support the disc pulling unit and the speed reducer support unit.

[0033] The reducer support unit includes a left jack 1, a right jack 2, and a support platform 3, which is mounted and fixed on the left jack 1 and the right jack 2. The left jack 1 and the right jack 2 can drive the support platform 3 to adjust its vertical position, and the support platform 3 is used to support and fix the reducer.

[0036] Therefore, the quick-release device for speed reducers according to the present invention is suitable for the quick disassembly and installation of KA series speed reducers, especially for maintenance scenarios using large speed reducers.

[0037] In some embodiments of this utility model, the platform support unit includes an upper panel 7, a lower panel 8, and four support rods 9. The upper panel 7 is fixedly connected to the upper end of each support rod 9, and the lower panel 8 is fixedly connected to the lower end of each support rod 9. Depending on actual usage requirements, each support rod 9 can be configured as a structure composed of multiple sections connected sequentially to accommodate different usage heights.

[0038] An inclined reinforcing rib 10 is also connected between two adjacent support rods 9 to improve the overall structural strength and reliability of the platform support unit.

[0039] Multiple casters 11 are installed at the bottom of the lower panel 8 of the support unit to make the quick-release device for the reducer easy to move and more flexible and convenient to use.

[0040] During the disassembly of the speed reducer, the platform support unit can support the speed reducer during its descent, reducing the labor intensity of the workers.

[0041] In some embodiments of this utility model, a first slide rail 12 and a second slide rail 13 that are parallel to each other are installed on the upper panel 7 of the support unit. A first slider and a second slider are connected to the bottom of the left jack 1 and the right jack 2 respectively. The first slider is slidably engaged with the first slide rail 12, and the second slider is slidably engaged with the second slide rail 13, thereby realizing the forward and backward movement of the left jack 1 and the right jack 2 on the upper panel 7 of the support unit.

[0042] A middle slide rail 14 is installed on the upper panel 7 of the support unit. The middle slide rail 14 is located between the first slide rail 12 and the second slide rail 13, and is parallel to the first slide rail 12 and the second slide rail 13 respectively. A middle slider is connected to the bottom of the disc jack 4. The middle slider slides in cooperation with the middle slide rail 14, thereby realizing the forward and backward movement of the disc jack 4 on the upper panel 7 of the support unit.

[0043] That is, in this embodiment, the sliding fit structure between the first slider and the first slide rail 12, the sliding fit structure between the second slider and the second slide rail 13, and the sliding fit structure between the intermediate slider and the intermediate slide rail 14 are all the same.

[0044] like Figure 5As shown, the structure of the first slider 15 is provided. Multiple movable wheels 16 are mounted on the side of the first slider 15 for contacting the upper and lower planes of the first slide rail 12, thereby enabling the first slider 15 to slide along the first slide rail 12. A connecting plate 17 is fixedly provided on the top of the first slider 15 for connection and fixation to the bottom of the left jack 1. Similarly, the structures of the second slider and the middle slider are the same as those of the first slider 15.

[0045] Specifically, in this embodiment, the left jack 1, the right jack 2, and the disc jack 4 have the same structure. The disc jack 4 will be used as an example for explanation below.

[0046] The disc jack 4 includes a base 401, two lower connecting rods 402, two upper connecting rods 403, two connecting vertical blocks 404, one connecting horizontal block 405, and a long screw 406. The lower ends of the two lower connecting rods 402 are rotatably connected to the base 401, and the upper ends of the two lower connecting rods 402 are rotatably connected to the two connecting vertical blocks 404 respectively. The two connecting vertical blocks 404 are rotatably connected to the lower ends of the two upper connecting rods 403 respectively, and the upper ends of the two upper connecting rods 403 are rotatably connected to the connecting horizontal block 405, so that the two lower connecting rods 402 and the two upper connecting rods 403 can be closed to form a rhomboid structure. One of the connecting vertical blocks 404 is threadedly connected to the long screw 406, and the other connecting vertical block 404 has a through hole, through which the long screw 406 is rotatably connected via a bearing. A force-applying rod 407 is also provided at the operating end of the long screw 406. That is, the lever 407 can drive the long screw 406 to rotate in the forward or reverse direction to adjust the height of the jack.

[0047] A top seat 408 is fixedly installed on the connecting cross block 405. The top seat 408 is connected and fixed to the puller bracket 5, thereby realizing the height adjustment of the disc puller 6. Similarly, the top seats on the left jack 1 and the right jack 2 are connected and fixed to the support platform 3 to realize the height adjustment of the support platform 3.

[0048] By adjusting the left jack 1, right jack 2, and disc jack 4, the height of the support platform 3 and the disc puller 6 is made accurate and stable, ensuring the accuracy of the positioning of the quick-release device of the reducer during the pulling process and reducing the pulling difficulties caused by inaccurate positioning.

[0049] Specifically, the puller bracket 5 includes a support column 501 and a support ring 502, with the support ring 502 fixedly mounted on the support column 501. The disc puller 6 includes a disc 601 and a connecting ring 602. The disc 601 has a central hole 603 for aligning with the reducer shaft to be disassembled. The connecting ring 602 is fixedly mounted on one side of the central hole 603. The connecting ring 602 and the support ring 502 are rotatably connected via a bearing 604, allowing the disc puller 6 to rotate on the puller bracket 5.

[0050] The disc 601 is also provided with multiple positioning holes 605. The arrangement of each positioning hole 605 is consistent with the relative position of the disassembly hole of the KA series reducer, so as to meet the disassembly and use process of the KA series reducer in the workshop.

[0051] The quick-release device for a speed reducer according to this utility model embodiment aligns the positioning hole 605 on the disc puller 6 with the disassembly hole of the speed reducer and connects them with screws during the disassembly process. During the pulling process, the speed reducer shaft is held in place by a hydraulic puller, and the hooks are engaged with the edge of the disc of the disc puller 6. The hydraulic start rod of the hydraulic puller moves forward to make the hooks retract, and the speed reducer moves out of the shaft as the hooks retract. When the speed reducer is disassembled, it moves out with the slide rail.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
