Description

Technical Field

[0001] This utility model relates to the field of hoisting device technology, and in particular to a hoisting device for steel truss floor slabs that is easy to adjust. Background Technology

[0002] A truss made of steel bars as the top chord, bottom chord, and web members, connected by resistance spot welding, is called a steel truss. A composite load-bearing plate made by connecting the steel truss and the base plate by resistance spot welding is called a steel truss floor deck. The usual simple hoisting method is to use ropes for binding, which is inconvenient when binding steel truss floor decks of different specifications. Therefore, it is necessary to improve the existing technology. To this end, we propose an easily adjustable steel truss floor deck hoisting device. Utility Model Content

[0003] The present invention mainly addresses the technical problems existing in the prior art and provides an easily adjustable steel truss floor deck hoisting device.

The lifting block is fixedly installed on the hook of the crane. A sliding groove is provided at the lower end of the lifting block. Two sliding blocks are slidably installed inside the sliding groove. Two lifting ropes are fixedly installed at the lower end of the sliding block. An installation block is fixedly installed at the lower end of each of the two lifting ropes. A constraint frame is fixedly installed at the lower end of each of the two installation blocks. A limit protrusion is fixedly installed on the bottom side of each of the two constraint frames. A support rod is provided inside the two corresponding constraint frames. Limiting grooves that are adapted to the limit protrusions are provided at equal intervals on the bottom side of the support rods.

[0005] Preferably, the constraint frame has a circular hole on its bottom side, through which the limiting protrusion passes. The support rod has a first threaded hole at equal intervals on its upper side, corresponding to the position of the limiting groove. The first threaded hole is internally threaded with a first threaded post, which passes through the circular hole on the bottom side of the constraint frame. A rotating handle is fixedly installed at the lower end of the first threaded post.

[0010] Beneficial effects

[0011] This utility model provides an easily adjustable hoisting device for steel truss floor decking. It has the following beneficial effects:

[0012] (1) The adjustable steel truss floor deck hoisting device adjusts the position of the lifting rope by adjusting the position of the sliding block. The two lifting ropes on one sliding block are respectively placed on both sides of the steel truss floor deck.

[0022] like Figures 1-4As shown, an easily adjustable steel truss floor deck hoisting device includes a lifting block 1 and a crane. The lifting block 1 is fixedly installed on the hook of the crane. A sliding groove 15 is provided at the lower end of the lifting block 1. Two sliding blocks 2 are slidably installed inside the sliding groove 15. Two lifting ropes 3 are fixedly installed at the lower end of the sliding blocks 2. An installation block 4 is fixedly installed at the lower end of each of the two lifting ropes 3. A constraint frame 5 is fixedly installed at the lower end of each of the two installation blocks 4. A constraint frame 5 is fixedly installed on the bottom side of each of the two constraint frames 5. The limiting protrusion 6 has a support rod 7 inside each of the two corresponding constraint frames 5. The bottom side of the support rod 7 has equidistant limiting grooves 8 that match the limiting protrusion 6. The limiting grooves 8 are triangular, and the limiting protrusion 6 is a triangular block. The position of the lifting rope 3 is adjusted by adjusting the position of the sliding block 2. Two lifting ropes 3 on one sliding block 2 are respectively placed on both sides of the steel truss floor slab. The sides of the lifting ropes 3 are in contact with the stacked steel truss floor slab lifting blocks 1. The support rod 7 passes through the interior of the two constraint frames 5, so that the limiting protrusion 6 is locked inside the limiting groove 8 to constrain the movement of the support rod 7. The weight of the steel truss floor deck itself keeps the support rod 7 relatively stationary inside the constraint frame 5. The position of the limiting protrusion 6 locked inside the limiting groove 8 is used to adjust the width of the lifting steel truss floor deck, thereby adapting to different models of steel truss floor decks and further ensuring stability during the lifting process. The side of the lifting block 1 is marked with scale marks 18, which are used to determine the lifting position of the two support rods 7 and maintain balance. The side of the mounting block 4 is marked with a second threaded hole 12, and the inside of the second threaded hole 12 is threaded with a second threaded post 13. When lifting, the second threaded post 13 is rotated, and the second threaded post 13 squeezes the side of the bottom steel truss floor deck to reduce the movement gap of the steel truss floor deck and reduce the relative sway of the steel truss floor deck during the movement.

[0023] A circular hole is provided on the bottom side of the constraint frame 5. The circular hole on the bottom side of the constraint frame 5 passes through the limiting protrusion 6. A first threaded hole 9 is provided on the upper side of the support rod 7 at equal intervals corresponding to the position of the limiting groove 8. A first threaded post 10 is threaded inside the first threaded hole 9. The first threaded post 10 passes through the circular hole on the bottom side of the constraint frame 5. A rotating handle 11 is fixedly installed at the lower end of the first threaded post 10. The movement of the constraint frame 5 and the support rod 7 is further locked by the first threaded post 10.

[0024] Both ends of the lifting block 1 are provided with mounting cavities 14. A fixed rotary motor 16 is installed inside the mounting cavity 14. A threaded hole is provided on the side of the sliding block 2. A lead screw 17 is fixedly installed at the output end of the rotary motor 16. The lead screw 17 is threaded into the threaded hole on the side of the sliding block 2.

[0025] The working principle of this utility model:

[0026] In use, the position of the lifting rope 3 is adjusted by adjusting the position of the sliding block 2. Two lifting ropes 3 on one sliding block 2 are respectively placed on both sides of the steel truss floor slab. The sides of the lifting ropes 3 are in contact with the stacked steel truss floor slab lifting blocks 1. The support rod 7 is then passed through the interior of the two constraint frames 5, so that the limiting protrusion 6 is engaged inside the limiting groove 8 to constrain the movement of the support rod 7. The weight of the steel truss floor slab itself keeps the support rod 7 relatively stationary inside the constraint frames 5. The position of the limiting protrusion 6 engaged inside the limiting groove 8... The width of the lifting steel truss floor slab is adjusted to accommodate different models of steel truss floor slabs, further ensuring stability during lifting. The first threaded post 10 further locks the movement of the constraint frame 5 and the support rod 7. During lifting, the second threaded post 13 is rotated, and the second threaded post 13 presses against the side of the bottom steel truss floor slab to reduce the movement gap of the steel truss floor slab and reduce the relative sway of the steel truss floor slab during movement. The lifting position of the two support rods 7 is determined by the scale mark 18 to maintain balance.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
