Description

Technical Field

[0001] This application relates to the technical field of jacking equipment, and particularly relates to a jacking machine for a steel structure beam used in the installation of a corridor. Background Art

[0002] A corridor is a carrier of a belt conveyor and is a special facility set up for continuously transporting materials such as coal and ore by a belt conveyor. After the mined coal is transported to the ground through the main shaft facilities, the corridor and transfer stations are usually used to connect each belt conveyor transmission system to transport the coal to the coal bunker or coal washing plant; the corridor consists of a long corridor and corridor supports. When installing the corridor, steel structure beams are generally used, and some jacking machines are used during the assembly of the steel structure beams. However, the existing jacking machines have a relatively single lifting method, and generally have a limited lifting height and cannot perform multi-level adjustment. When jacking the steel structure beam, relative sliding will occur, resulting in a low safety factor. Summary of the Invention

[0003] In order to improve the problem that the lifting method of the above-mentioned jacking machine is relatively single, the present invention provides a jacking machine for a steel structure beam used in the installation of a corridor.

[0004] The present invention provides a jacking machine for a steel structure beam used in the installation of a corridor, adopting the following technical solution: A jacking machine for a steel structure beam used in the installation of a corridor includes a main lifting mechanism placed on the ground. A fixed frame is installed at the upper end of the main lifting mechanism. A multi-level jacking mechanism is slidably installed at the upper end of the fixed frame. The multi-level jacking mechanism includes a first jacking frame, a second jacking frame, and a third jacking frame. The fixed frame and the first jacking frame, the first jacking frame and the second jacking frame, and the second jacking frame and the third jacking frame are all cooperated with each other in a sliding manner. A main pulley is rotatably connected to the outer wall of the fixed frame. A forward and reverse motor is fixedly provided outside the fixed frame. The output shaft end of the forward and reverse motor is fixedly connected to the main pulley. Two auxiliary wheels are rotatably provided on both sides of the upper end of the outer wall of the fixed frame. Both groups of auxiliary wheels are connected to the main pulley by a belt.

[0005] Based on the above technical features: Compared with traditional jacking machines, this jacking machine is equipped with a multi-stage jacking mechanism. When starting the operation, the main lifting mechanism can first lift the steel structure beam to an appropriate height. Then, start the forward and reverse motor and drive the main pulley to rotate clockwise. At this time, the third jacking frame can first slide upward and lift the height of the steel structure beam for the second time. If the required installation height is not reached, continue to rotate the main pulley. At this time, the second jacking frame can slide upward and lift the height of the steel structure beam for the third time. If the required height is still not reached, continue to rotate the main pulley. At this time, the first jacking frame can slide upward and lift the height of the steel structure beam for the third time. The jacking height of the steel structure beam can be fine-tuned repeatedly according to needs. After the jacking is completed, the main pulley can be rotated in the reverse direction to store all the jacking frames, reducing the space and facilitating the actual jacking requirements more conveniently.

[0013] Based on the above technical features: when the third lifting frame starts to rise and until the long raised block contacts the fixed raised block, the fixed raised block can be used to drive the second lifting frame to rise upward; if the long raised block of the second lifting frame contacts the fixed raised block on the first lifting frame after it rises, the first lifting frame can be driven to continue to rise upward, thereby completing the multi-stage lifting operation.

[0024] In summary, the present invention has at least the following beneficial effects:

[0025] 1. Compared with traditional lifting machines, this lifting machine is added with a multi-stage lifting mechanism. At the beginning of the operation, the steel structure beam can be first lifted to an appropriate height by the main lifting mechanism, and then the positive and negative rotation motor is started to drive the main pulley to rotate clockwise. At this time, the third lifting frame can slide upward first to lift the height of the steel structure beam for the second time. If the required installation height is not reached, the main pulley continues to rotate. At this time, the second lifting frame can slide upward to lift the height of the steel structure beam for the third time. If the required height is still not reached, the main pulley continues to rotate. At this time, the first lifting frame can slide upward to lift the height of the steel structure beam for the third time. The lifting height of the steel structure beam can be fine-tuned as needed. After the lifting is completed, the main pulley can be rotated in the reverse direction to store all the lifting frames, reducing the space and being more convenient for the actual needs of lifting;

[0036] The following is a further detailed description of the present invention in conjunction with the attached Figure 1-6 drawings.

[0037] Please refer to Figure 1-2, a jacking machine for a steel structure beam used in corridor installation provided by the present invention includes a main lifting mechanism 1 placed on the ground. A fixed frame 2 is installed at the upper end of the main lifting mechanism 1. A multi-stage jacking mechanism 3 is slidably installed at the upper end of the fixed frame 2. The multi-stage jacking mechanism 3 includes a first jacking frame 31, a second jacking frame 32, and a third jacking frame 33. The fixed frame 2 and the first jacking frame 31, the first jacking frame 31 and the second jacking frame 32, and the second jacking frame 32 and the third jacking frame 33 are all cooperated with each other in a sliding manner. A main pulley 21 is rotatably connected to the outer wall of the fixed frame 2. A forward and reverse motor 211 is fixedly installed outside the fixed frame 2. The output shaft end of the forward and reverse motor 211 is fixedly connected to the main pulley 21. Two auxiliary pulleys 22 are rotatably arranged on both sides of the upper end of the outer wall of the fixed frame 2. Both groups of auxiliary pulleys 22 are connected to the main pulley 21 by belts. Compared with the traditional jacking machine, this jacking machine adds a multi-stage jacking mechanism 3. After the jacking is completed, the main pulley 21 can be rotated in the reverse direction to store all the jacking frames, reducing the space and being more convenient for the actual jacking requirements.

[0038] A movable pulley 4 and a fixed pulley 5 are rotatably connected to the outer walls of the first jacking frame 31 and the second jacking frame 32 respectively. A belt is connected between the movable pulley 4 and the fixed pulley 5. And a belt is connected between the movable pulley 4 on the first jacking frame 31 and the auxiliary pulley 22. When the main pulley 21 is rotated by the forward and reverse motor 211, the auxiliary pulley 22, the movable pulley 4, and the fixed pulley 5 can be driven to rotate together by the belt. A positioning block 331 is fixedly installed at the bottom side of the surface of the third jacking frame 33. A belt is connected between the positioning block 331 and the fixed pulley 5 on the second jacking frame 32. When the main pulley 21 rotates clockwise, the belt can be contracted and pull up the positioning block 331 upward. At this time, the third jacking frame 33 can slide upward first and jack up the steel structure beam upward.

[0039] The height of the movable pulley 4 is lower than that of the fixed pulley 5. And the belt between the positioning block 331 and the fixed pulley 5 on the same side, the belt between the pulleys, the belt between the movable pulley 4 and the auxiliary pulley 22, and the belt between the auxiliary pulley 22 and the main pulley 21 are all the same belt. When the main pulley 21 rotates clockwise, the belt can contract inward, drive the pulleys to rotate correspondingly, and pull up the positioning block 331 upward. When the main pulley 21 rotates counterclockwise, the positioning block 331 can continuously descend to the initial position.

[0040] On both sides of the outer wall of the fixed support 2, both sides of the outer wall of the first jacking frame 31, and both sides of the outer wall of the second jacking frame 32, fixed convex blocks 6 are welded. On both sides of the outer wall of the first jacking frame 31, both sides of the outer wall of the second jacking frame 32, and both sides of the outer wall of the third jacking frame 33, long strip convex blocks 7 are welded. The height of each group of long strip convex blocks 7 is lower than the corresponding fixed convex block 6 and is in contact and snap-fit with the corresponding fixed convex block 6. When the third jacking frame 33 starts to rise and until the long strip convex block 7 contacts the fixed convex block 6, the fixed convex block 6 can be used to drive the second jacking frame 32 to rise. If the long strip convex block 7 after the second jacking frame 32 rises contacts the fixed convex block 6 on the first jacking frame 31, the first jacking frame 31 can be driven to continue rising, so as to complete the multi-stage jacking operation.

[0041] Please refer to Figure 3 , the main lifting mechanism 1 includes a bottom plate 11, an electric control cylinder 12, a cross bar 13, a folding frame 14 and an upper top plate 15. The electric control cylinder 12 is fixedly arranged on the surface of the bottom plate 11. The output shaft end of the electric control cylinder 12 is fixedly connected with a piston push rod 121. The piston push rod 121 is fixedly connected with the cross bar 13. And a folding frame 14 is fixedly connected to the outside of the cross bar 13. The upper end of the folding frame 14 is connected with the upper top plate 15. The fixed support 2 is detachably installed on the surface of the upper top plate 15. At the beginning of jacking, the electric control cylinder 12 can be used to drive the piston push rod 121 to contract and drive the folding frame 14 to unfold, so that the upper top plate 15 jacks up the fixed support 2 to the maximum lifting height, and facilitates the subsequent jacking fine-tuning operation.

[0042] Please refer to Figure 6 , on both sides of the outer wall of the fixed support 2, both sides of the outer wall of the first jacking frame 31, and both sides of the outer wall of the second jacking frame 32, sliding grooves 10 are opened. On the inner side walls of the first jacking frame 31, the second jacking frame 32 and the third jacking frame 33, sliding members 101 are arranged oppositely. The sliding members 101 are in sliding fit with the sliding grooves 10. When the first jacking frame 31, the second jacking frame 32 and the third jacking frame 33 are performing jacking operations, they can all be guided and slid through the sliding members 101 in the corresponding sliding grooves 10.

[0043] Please refer to Figure 2 , a channel 332 is opened on the upper end surface of the third jacking frame 33. On both sides of the surface of the channel 332, sliding blocks 8 are slidably installed. There are two groups of sliding blocks 8 arranged oppositely, and elastic clamping pads 81 are fixedly arranged on the inner sides of the two groups of sliding blocks 8. When the sliding blocks 8 approach each other, the elastic clamping pads 81 can clamp and fix the steel structure beam placed on the third jacking frame 33.

[0044] Please refer to Figure 4A slide rail 23 is also fixed on the outer wall of the fixed frame 2, and a slide plate 231 is installed on the surface of the slide rail 23. A connecting rod 212 is movably hinged at the surface edge of the main pulley 21, and the end of the connecting rod 212 away from the main pulley 21 is movably hinged to the slide plate 231, and fixed sleeve rods 9 are movably hinged on both sides of the outer wall of the slide plate 231, and the end of the fixed sleeve rod 9 away from the slide plate 231 is movably hinged to the slider 8. When the main pulley 21 rotates clockwise, the connecting rod 212 can drive the slide plate 231 to slide downward on the slide rail 23, and the fixed sleeve rods 9 on both sides of the slide plate 231 can drive the slider 8 to approach each other on the groove 332 and complete the clamping and fixing of the steel structure beam, so as to avoid relative sliding and some safety accidents when jacking the steel structure beam.

[0045] See also Figure 5 An extension rod 91 is slidably sleeved in the inner cavity of the fixed sleeve rod 9, and an active chamber 92 is provided in the inner cavity of the fixed sleeve rod 9, a limit block 921 is fixedly provided in the active chamber 92, both ends of the extension rod 91 extend into the active chamber 92 and are fixedly connected with a telescopic spring 911, and one end of the telescopic spring 911 away from the extension rod 91 is fixedly connected to the limit block 921. When the fixed sleeve rod 9 slides and rotates with the slide plate 231, the extension rod 91 can be used to stretch it, causing the telescopic spring 911 to deform and use the elastic force generated after the deformation to increase the clamping force of the elastic clamping pad 81 on the steel structure beam.

[0046] Working principle: At the beginning of the operation, the steel structure beam can be raised to an appropriate height through the main lifting mechanism 1, and then the forward and reverse motors 211 are started to drive the main pulley 21 to rotate clockwise. At this time, the third jacking frame 33 can slide upward first and lift the height of the steel structure beam twice. If the required installation height is not reached, the main pulley 21 is continuously rotated. At this time, the second jacking frame 32 can slide upward and lift the height of the steel structure beam three times. If the required height is still not reached, the main pulley 21 is continuously rotated. At this time, the first jacking frame 31 can slide upward and lift the height of the steel structure beam three times. The lifting height of the steel structure beam can be repeatedly fine-tuned as needed. After the jacking is completed, the main pulley 21 can be rotated in the opposite direction and all the jacking frames can be stored.

[0047] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
