Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, and in particular to a hoisting device for installing a support beam. Background Technology

[0002] Support beams are commonly used engineering structural components, mostly made of metal materials such as carbon steel and stainless steel. They consist of beams, connectors, and supports. With their I-shaped or channel-shaped cross-section designs and stable connection methods, they have good strength and rigidity. They are widely used in construction, industry, power and other fields. They support ventilation ducts in building basements, suspend industrial pipelines in factory workshops, and fix busbars in substations. They play an important role in supporting and suspending pipelines, cables and other equipment, ensuring the stable operation of facilities.

[0003] In indoor scaffolding beam installation operations, small overhead cranes are widely used due to their flexibility and convenience. However, the conventional rope hoisting method has significant drawbacks: during actual operation, instability such as swaying and shaking can easily occur, which not only affects the convenience of installation but also poses safety hazards, making it difficult to guarantee the reliability of the hoisting operation, and thus requires optimization and improvement.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A hoisting device for installing a support beam includes an n-shaped frame 1. The lower end of the frame 1 is rotatably connected to four rectangular casters 2 for easy movement of the frame 1. Support plates 3 are fixedly connected to the left and right sides of the frame 1 near the bottom for supporting the frame 1. The lower end of the support plate 3 is rotatably connected to a second caster for easy movement of the frame 1. A triangular fixing block 4 is fixedly connected between the upper side wall of the support plate 3 and the outer side wall of the frame 1 for fixing the support plate 3.

[0022] In this embodiment, a winch 7 is fixedly connected to the upper end of the frame 1 for winding and unwinding the first lifting rope 6. The first lifting rope 6 is fixedly connected to the drum of the winch 7 for driving the lifting plate 5 to rise. An opening is provided at the top inner part of the frame 1. A horizontally arranged lifting plate 5 is slidably connected to the inner wall of the frame 1 near the top position for cooperating with the support block 8 and the second lifting rope 9 to drive the hook 10 to rise and fall. The lower end of the first lifting rope 6 slides through the opening and is fixedly connected to the upper end of the lifting plate 5.

[0023] In this embodiment, guide blocks 15 are fixedly connected to both ends of the lifting plate 5 to guide the lifting plate 5 in a lifting manner in conjunction with the guide groove. The inner side wall of the frame 1 is provided with a guide groove corresponding to the guide block 15. The end of the guide block 15 away from the lifting plate 5 slides into the guide groove. The end of the guide block 15 away from the lifting plate 5 is provided with an arc-shaped groove. A ball is rolled on the inner side wall of the arc-shaped groove to reduce the friction between the guide block 15 and the inner wall of the guide groove when the guide block 15 moves. The ball passes through the arc-shaped groove. A vertically arranged first guide rod 16 is slidably inserted into the guide block 15 to guide the lifting of the guide block 15. The two ends of the first guide rod 16 pass through the guide block 15 and are fixedly connected to the inner side wall of the guide groove.

[0024] In this embodiment, the lower end of the lifting plate 5 is provided with a T-shaped sliding groove. Multiple T-shaped support blocks 8 are slidably connected to the inner side wall of the sliding groove to support the second hoisting rope 8. Four rectangularly distributed second guide rods 12 are slidably inserted into the upper end of the support block 8 to prevent the spring 13 from tilting. A horizontally arranged connecting plate 11 is fixedly connected to the upper end of the second guide rod 12 to support the spring 13. The spring 13 is slidably sleeved on the second guide rod 12 to give the support block 8 a downward elastic thrust. The two ends of the spring 13 abut against the connecting plate 11 and the support block 8 respectively.

[0025] In this embodiment, a locking block 14 is fixedly connected to the lower side wall of the support block 8, which is used to limit the support block 8 in conjunction with the locking groove. The lower end of the locking block 14 is tapered to reduce the difficulty of inserting the locking block 14 into the locking groove. Multiple locking grooves corresponding to the locking block 14 are distributed from left to right in the inner bottom of the slide. The lower end of the locking block 14 slides into the locking groove. The lower end of the support block 8 passes through the slide and is fixedly connected to a second lifting rope 9 to support the lifting hook 10. The lower end of the second lifting rope 9 is fixedly connected to the lifting hook 10 for hoisting the support beam.

[0026] In this embodiment, firstly, pushing the support block 8 upward causes the locking block 14 to move out of the slot. At this time, the support block 8 can be pushed left or right to flexibly adjust the position of the hook 10. After adjustment, the support block 8 is released, allowing it to fall back to its original position under its own weight, or it can be manually pulled down, causing the support block 8 to drive the locking block 14 back into the slot, thus locking the position. During this process, the two ends of the spring 13 abut against the connecting plate 11 and the support block 8 respectively, using its elasticity to provide downward thrust, effectively preventing the locking block 14 from coming loose from the slot, significantly improving reliability. Then, the winch 6 is started to wind up the first lifting rope. 6. Pull the lifting plate 5 up. During the lifting process, the lifting plate 5 drives the guide block 15 to slide in the guide groove. The guide block 15 cooperates with the first guide rod 16 to ensure that the lifting plate 5 remains stable during lifting. Finally, the lifting plate 5 drives the support beam to rise slowly through the second lifting rope 9. In addition, the first universal wheel 2 and the second universal wheel at the bottom of the frame 1 make it easy for users to move and adjust the position of the frame 1 flexibly according to actual needs. Multiple adjustable hooks 10 can reasonably distribute the lifting force according to the structural characteristics of the support beam, which greatly improves the stability of the lifting operation.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
