Description

A multi-functional hoisting device for construction equipment Technical Field

[0001] This utility model belongs to the field of hoisting equipment technology, and in particular relates to a multi-functional hoisting device for construction equipment. Background Technology

[0002] In high-altitude construction projects, it is very troublesome to move materials from the ground to a high place. Therefore, hoisting equipment is often used to transport and transfer heavy goods. When using it, the hoisting equipment is usually installed at a high place, and materials on the ground are hoisted to the high place by using hoisting ropes and lifting tools.

[0003] Lifting equipment typically uses a single rope to lift materials from the ground to a higher position via a lifting device. The rope is then released to lower the lifting device back to the ground for another lift. However, in practice, the descent of the lifting device takes up half of the entire lifting process, during which it cannot perform any ineffective work. Therefore, all energy consumed during this process is wasted, and the entire process is also wasted, resulting in low lifting efficiency. Summary of the Invention

[0004] This utility model provides a multi-functional hoisting device for construction equipment, which aims to solve the problems of wasted time and energy consumption in the current hoisting process.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model provides a multi-functional hoisting device for construction equipment, as shown in Figures 1-5. It includes a fixed plate 1, with a first guide roller 2 and a second guide roller 3 mounted on the front side of the fixed plate 1. A support frame 4 is mounted on the upper end of the fixed plate 1, and a limiting sleeve 5 is mounted on the top of the support frame 4. A rotating shaft 6 is rotatably mounted inside the limiting sleeve 5. A first motor 7 is mounted on the rear side of the support frame 4, and the output shaft of the first motor 7 is connected to the shaft end of the rotating shaft 6. A first linear roller 8 and a second linear roller 9 are mounted on the front side of the rotating shaft 6. The first linear roller 8 and the second linear roller 9 are located in the same plane as the centers of the first guide roller 2 and the second guide roller 3, respectively. A hoisting rope 10 is wound around the surface of both the first linear roller 8 and the second linear roller 9, with the winding directions of the hoisting rope 10 being opposite. The hoisting rope 10 passes through the first guide roller 2 and the second guide roller 3. The device has a guide roller 3 and a lifting device 11 connected to its bottom. When in use, the first motor 7 is started, which drives the first roller 8 and the second roller 9 to rotate simultaneously. Since the lifting rope 10 has opposite winding directions on the surfaces of the first roller 8 and the second roller 9, the first roller 8 and the second roller 9 release and retract the rope respectively. The lifting rope 10 slides along the surfaces of the first guide roller 2 and the second guide roller 3 to release and retract the lifting device 11. When one lifting device 11 is raised, the other lifting device 11 is lowered, so that lifting work can be performed every time the first motor 7 is driven. By setting the first roller 8 and the second roller 9 to cooperate in releasing and retracting the lifting rope 10 simultaneously, this device solves the problem of energy waste of the first motor 7 during the lowering of the lifting device 11, and also doubles the lifting efficiency.

[0022] The fixed plate 1 has a groove inside, and a screw 12 is rotatably installed in the groove. A second motor 13 is installed on the right side of the fixed plate 1. The output shaft of the second motor 13 is connected to the rod end of the screw 12. A threaded sleeve 14 is fitted on the surface of the screw 12. A connecting block 21 is installed on the outside of the threaded sleeve 14. The central shaft of the second guide roller 3 is rotatably installed on the outside of the connecting block 21. By setting the screw 12 and the threaded sleeve 14, the second motor 13 can be started. The second motor 13 drives the screw 12 to rotate, while the threaded sleeve 14 slides horizontally under the action of the thread on the surface of the screw 12. This setting allows the position of the second guide roller 3 to be adjusted, thereby facilitating hoisting work from different positions and making the device more flexible in use.

[0023] The screw sleeve 14 fits into the inner wall of the groove of the fixing plate 1. The front side of the groove of the fixing plate 1 is provided with a sliding groove that is compatible with the connecting block 21. The horizontal sliding of the connecting block 21 is satisfied by opening a sliding groove on the front side of the fixing plate 1.

[0024] The rotating shaft 6 has a groove inside, and a transmission block 15 is slidably installed in the groove. Two sets of springs 16 are installed inside the groove of the rotating shaft 6, and the movable ends of the springs 16 are connected to the transmission block 15. The first wire roller 8 is installed on the outside of the rotating shaft 6 through a bearing sleeve. The inner side wall of the first wire roller 8 has a slot adapted to the transmission block 15. An electromagnetic pin 17 is installed on the top of the limiting sleeve 5. The output shaft of the electromagnetic pin 17 is connected to a plug rod 18. The surface of the first wire roller 8 has a slot adapted to the plug rod 18. A top block 19 is installed below the plug rod 18 and fits against the surface of the rotating shaft 6. The left end of the transmission block 15 is exposed outside the rotating shaft 6 and is located on the same straight line as the top block 19. By setting the transmission block 15, the rotating shaft 6 rotates through the transmission block 15. Block 15 drives the first wire roller 8 to rotate. When the device is finished and the wire needs to be wound up, the first motor 7 can be started to drive the first wire roller 8 and the second wire roller 9 to rotate simultaneously. The first wire roller 8 will first wind up the hanging rope 10. At this time, the hanging rope 10 of the second wire roller 9 is in the released state. At this time, the electromagnetic pin 17 can be started to push the insertion rod 18. The insertion rod 18 is inserted into the slot of the first wire roller 8. At the same time, the top block 19 pushes the transmission block 15 to embed it into the groove of the rotating shaft 6. At this time, the first wire roller 8 is disengaged from the transmission block 15 and is limited by the insertion rod 18 and cannot rotate. The first motor 7 is started again to drive the rotating shaft 6 to rotate in the opposite direction. At this time, the second wire roller 9 can wind up the hanging rope 10. By setting this mechanism, both the first wire roller 8 and the second wire roller 9 can quickly wind up the hanging rope 10.

[0025] The distance between the right end of the insertion rod 18 and the surface of the first wire roller 8 is less than the distance between the top block 19 and the transmission block 15. This setting can prevent the top block 19 from pushing the transmission block 15 back into the groove of the rotating shaft 6 before the insertion rod 18 is inserted into the slot of the first wire roller 8, which would cause the lifting rope 10 to be released due to the gravity of the lifting device 11 pulling the first wire roller 8 to rotate.

[0026] The top of the limiting sleeve 5 is equipped with a positioning frame 20. The inner side of the positioning frame 20 is provided with a slot that matches the insertion rod 18. By setting the positioning frame 20, the torque of the first roller 8 can be borne, thus preventing the movable rod of the electromagnetic pin 17 from being damaged by force.
