DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Please refer to the attached Figure 1-6 The utility model provides a traction seat hoisting tool, including a traction seat body 1 and a bracket 6. The top of the traction seat body 1 is a fork end, and four bosses 2 are arranged on the fork end. Each boss 2 is provided with a first threaded hole 3 (such as Figure 6As shown in FIG. 1 ), the bottom end of the traction seat body 1 is a mounting end, and a mounting end plate 4 is provided at the mounting end. A plurality of second threaded holes 5 are provided at the edge of the mounting end plate 4 (as shown in FIG. 1 ). Figure 6 As shown in the figure, a crossbeam 7 is arranged on the top of the bracket 6, and further comprises a first lifting assembly for lifting the mounting end of the traction seat body 1 downward, a second lifting assembly for lifting the fork end of the traction seat body 1 downward, and an adjusting assembly for lifting the traction seat body 1 for movement, and the first lifting assembly and the second lifting assembly are both connected to the crossbeam 7 through the adjusting assembly;

[0023] The adjustment component includes a first electric linear slide, which includes a moving base 8, a servo motor 9, a screw rod 10, a moving block 11, a limiting slide plate 12, a limiting hole 13 and a slide 14. The moving base 8 is arranged horizontally, and the top of the moving base 8 is fixedly installed on the bottom of the crossbeam 7. The servo motor 9 is fixedly installed on the side end of the moving base 8, and the output shaft of the servo motor 9 passes through the side end of the moving base 8. The screw rod 10 is arranged horizontally in the moving base 8, and the end of the screw rod 10 away from the servo motor 9 is rotatably connected to the side of the inner wall of the moving base 8, and the end of the screw rod 10 close to the servo motor 9 is fixedly connected to the output shaft of the servo motor 9, so when the servo motor 9 works, it can drive the screw rod 10 to rotate forward and reversely inside the moving base 8. The moving block 11 is threadedly connected to the surface of the screw rod 10, and the top of the limiting slide plate 12 is vertically fixedly installed at the bottom of the moving block 11. The limiting hole 13 is strip-shaped, and the limiting hole 13 is horizontally opened at the bottom of the moving base 8. The bottom end of the limiting slide plate 12 vertically passes through the limiting hole 13, and the surface of the limiting slide plate 12 fits with the hole wall of the limiting hole 13. That is, under the limiting action of the limiting hole 13, the limiting slide plate 12 can stably reciprocate laterally. Therefore, when the screw rod 10 rotates forward and reverse, the moving block 11 threadedly connected to the surface of the screw rod 10 can be converted from rotational motion to linear motion under the common limiting action of the limiting slide plate 12 and the limiting hole 13. That is, the moving block 11 can stably reciprocate laterally inside the moving base 8, and the top of the slide 14 is fixedly installed at the bottom end of the limiting slide plate 12. Therefore, when the moving block 11 reciprocates laterally, the slide 14 can be driven to reciprocate laterally synchronously through the limiting slide plate 12, so that the traction seat body 1 can be moved left and right to adjust the appropriate position during the hoisting process;

[0024] The adjustment component also includes a second electric linear slide 15, which has the same structure as the first electric linear slide, that is, the working principle of the second electric linear slide 15 is the same as that of the first electric linear slide, and the second electric linear slide 15 is arranged longitudinally, and the top of the second electric linear slide 15 is fixedly installed at the bottom of the slide 14, so the second electric linear slide 15 can stably reciprocate laterally, and a connecting plate 16 is fixedly installed at the output end of the second electric linear slide 15, so when the second electric linear slide 15 works, it can drive the connecting plate 16 to reciprocate longitudinally, so that the traction seat body 1 can move forward and backward to adjust the appropriate position during the hoisting process;

[0025] The first hoisting assembly includes a first electric lifting rod 17, which is vertically arranged. The top of the first electric lifting rod 17 is fixedly installed on one side of the bottom of the connecting plate 16. The output shaft of the first electric lifting rod 17 is fixedly installed with a limit plate 18. The bottom of the limit plate 18 is fixedly installed with a plug plate 19. The plug plate 19 is provided with a third threaded hole 20. Therefore, when the staff is performing the downward hoisting operation of the installation end of the traction seat body 1, the plug plate 19 can be inserted between the bosses 2 at the fork end of the traction seat body 1, and the bolts can be fixed through the convex 20 by means of bolts and nuts. The first threaded hole 3 provided on the platform 2 and the third threaded hole 20 provided on the plug plate 19 enable the fork end of the traction seat body 1 to be fixed on the plug plate 19, and then the first electric lifting rod 17 is started to drive the traction seat body 1 to move up and down, so that the installation end of the traction seat body 1 is suspended downward. Since the first electric lifting rod 17 is fixed and does not shake like a lifting rope or an iron chain, the posture of the traction seat body 1 is stable during the lifting and moving process, avoiding rotation and swinging, and having high safety, and no adjustment operation is required by the staff, which is beneficial to the production efficiency of the traction seat.

[0026] The second lifting assembly includes a second electric lifting rod 21, which is vertically arranged. The top end of the second electric lifting rod 21 is fixedly mounted on the other side of the bottom of the connecting plate 16. The output shaft of the second electric lifting rod 21 is fixedly mounted with a fixing plate 22. A fourth threaded hole 23 is provided at the edge of the fixing plate 22. Therefore, when the staff is performing the downward lifting operation of the fork end of the traction seat body 1, the fixing plate 22 and the mounting end plate 4 of the traction seat body 1 can be fixed by bolts and nuts, so that the mounting end plate 4 of the traction seat body 1 is fixed on the fixing plate 22. Then, the second electric lifting rod 21 is started to drive the traction seat body 1 to move up and down, so that the fork end of the traction seat body 1 is lifted downward. Since the second electric lifting rod 21 is fixed and does not shake like a lifting rope or an iron chain, the traction seat body 1 has a stable posture during the lifting and moving process, and rotation and swinging are avoided. The safety is high, and the staff does not need to perform adjustment operations, which is beneficial to the production efficiency of the traction seat.

[0027] The use process of the utility model is as follows: when the staff is performing the downward hanging operation of the mounting end of the traction seat body 1, the plug plate 19 can be inserted between the bosses 2 at the fork end of the traction seat body 1, and the bolts and nuts are fixed by passing the bolts through the first threaded holes 3 provided on the bosses 2 and the third threaded holes 20 provided on the plug plate 19, so that the fork end of the traction seat body 1 is fixed on the plug plate 19, and then the staff controls the traction seat body 1 to be hoisted and moved to a suitable position through the first electric linear slide and the second electric linear slide 15, that is, moved to the top of the clamp, and then the staff starts the first electric lifting rod 17 to drive the traction seat body 1 to move downward, that is, the mounting end of the traction seat body 1 is hung downward, and because the first electric lifting rod 17 is fixed, it does not shake like the lifting rope or the iron chain, so the traction seat body 1 is in a stable posture during the hoisting and moving process, avoiding rotation and swinging, with high safety, and no adjustment operation is required by the staff, which is conducive to traction. The production efficiency of the guide seat is improved. Similarly, when the staff is performing the downward lifting operation of the fork end of the traction seat body 1, the fixing plate 22 and the mounting end plate 4 of the traction seat body 1 can be fixed by bolts and nuts, so that the mounting end plate 4 of the traction seat body 1 is fixed on the fixing plate 22. Then the staff controls the lifting and moving of the traction seat body 1 to a suitable position through the first electric linear slide and the second electric linear slide 15, that is, moves it to just above the clamp. Then the staff starts the second electric lifting rod 21 to drive the traction seat body 1 to move up and down, and realizes the downward lifting of the fork end of the traction seat body 1. Therefore, the utility model can simultaneously meet the needs of the downward lifting operation of the fork end of the traction seat body 1 and the downward lifting operation of the mounting end of the traction seat body 1, and can also make the traction seat body 1 stable in the lifting and moving process to avoid rotation and swinging. It has high safety and does not require the staff to perform adjustment operations, which is beneficial to the production efficiency of the traction seat.
