Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a hoisting device for steel structure construction. Background Technique

[0002] With the strong promotion of green buildings and prefabricated buildings in China, steel structure buildings with the characteristics of green buildings and prefabricated buildings have developed rapidly. During the construction process, hoisting equipment is required to hoist and transfer I-beams. For example, the patent document with the publication number CN220467304U discloses a hoisting device for construction steel structures. When clamping an I-beam, first use an external machine to drag it above the base, and then start the motor to drive the two threaded sleeves on the double-headed screw to move towards the middle. The clamping blocks on both sides will extend into the grooves on both sides of the I-beam and clamp its surface. However, in the above patent, the clamping blocks only clamp the web of the I-beam, and the friction between the web of the I-beam and the clamping blocks is basically not the same everywhere, and there is a certain distance between the clamping blocks and the upper and lower flange plates. Then, during the hoisting process, the I-beam may slide in the up and down direction relative to the clamping blocks, resulting in the I-beam tilting relative to the clamping blocks, which poses a certain safety hazard.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] The present utility model will be further described below in conjunction with the accompanying drawings:

[0024] As Figures 1-6As shown in the figure, a hoisting device for steel structure construction includes two hoisting shells 1. A lifting ring 101 is welded to the top of the hoisting shell 1. The lifting ring 101 is connected to a hoisting machine through a lifting rope 102. A bidirectional moving mechanism is arranged inside the hoisting shell 1, and a clamping mechanism is arranged below the hoisting shell 1. The bidirectional moving mechanism is used to drive the clamping mechanism to move. The clamping mechanism includes two symmetrically arranged support shells 301. A first sliding rod 302 is slidably connected inside the support shell 301. One ends of the two first sliding rods 302 close to each other extend out of the support shell 301 and are fixedly connected to a clamping plate 303. During hoisting, the two hoisting shells 1 are respectively moved above the I-beam 7 and close to both ends of the I-beam 7, so that the clamping plates 303 are located on the front and back sides of the I-beam 7. Then the bidirectional moving mechanism makes the two clamping plates 303 approach each other to clamp the web of the I-beam 7. An elastic mechanism for automatically extending the first sliding rod 302 out of the support shell 301 is arranged inside the support shell 301. Top pressure support mechanisms are arranged on both the top wall and the bottom wall of the support shell 301. An extrusion block 304 for moving the top pressure support mechanism up and down is fixedly connected to the first sliding rod 302. An auxiliary mechanism is arranged on one side of the hoisting shell 1.

[0025] The top pressure support mechanism includes a second sliding rod 401. The second sliding rod 401 is slidably connected to the support shell 301 in the vertical direction. One end of the second sliding rod 401 extends out of the support shell 301 and is welded with a top pressure plate 402. The other end of the second sliding rod 401 is connected with a T-shaped slider 403 by screws. The extrusion block 304 includes upper and lower symmetric inclined surfaces. A T-shaped groove 305 is opened on the inclined surface. The extrusion block 304 is slidably fitted in the T-shaped groove 305. When the second sliding rod 401 translates relative to the extrusion block 304, the T-shaped slider 403 slides along the T-shaped groove 305, so that the upper and lower two top pressure plates 402 approach or move away from each other.

[0026] The elastic mechanism includes a fixed sleeve 501. A sliding plate 502 is slidably connected inside the fixed sleeve 501. One end of the first sliding rod 302 away from the clamping plate 303 is fixedly connected to the sliding plate 502. A spring 503 is fixedly connected between the sliding plate 502 and the inner wall of the fixed sleeve 501. After the clamping plate 303 clamps the web of the I-beam 7, the support shell 301 continues to drive the fixed sleeve 501 to move, and the first sliding rod 302 begins to retract into the support shell 301, thereby compressing the spring 503. When the two support shells 301 move away from each other and the clamping plate 303 leaves the I-beam 7, the clamping plate 303 gradually rebounds, so that the first sliding rod 302 extends out of the support shell 301 again and returns to the initial position.

[0027] The bidirectional moving mechanism includes a bidirectional lead screw 201, which is connected to the hoisting housing 1 through bearings. Two symmetrically arranged moving plates 202 are threadedly connected to the bidirectional lead screw 201. The moving plates 202 are slidably connected to the hoisting housing 1. The bottom ends of the moving plates 202 extend out of the hoisting housing 1 and are fixedly connected to the support housing 301. One end of the bidirectional lead screw 201 is fixedly connected to a first handwheel 203. When the bidirectional lead screw 201 rotates, it will drive the two moving plates 202 to approach or move away from each other, so that the moving plates 202 drive the support housing 301 to move, realizing the clamping or loosening of the I-beam 7 by the clamping mechanism.

[0028] A force-bearing plate 204 is fixedly connected to the moving plate 202. A ball 205 is movably embedded at the bottom of the force-bearing plate 204, and the ball 205 contacts the inner bottom wall of the hoisting housing 1. By providing the force-bearing plate 204, the force-bearing strength of the moving plate 202 can be improved. By providing the ball 205, the friction between the force-bearing plate 204 and the hoisting housing 1 can be reduced, facilitating the translation of the moving plate 202.

[0029] The auxiliary mechanism includes a guide rail 601, which is welded to one side of the hoisting housing 1. A unidirectional lead screw 602 is rotatably connected in the guide rail 601. A lifting block 603 is threadedly connected to the unidirectional lead screw 602. The lifting block 603 is slidably connected to the guide rail 601. A support rod 604 is welded to one side of the lifting block 603. The support rod 604 is inclined. A friction plate 605 is welded to the bottom end of the support rod 604. The top of the unidirectional lead screw 602 is fixedly connected to a second handwheel 606. Due to the pulling force of the lifting rope 102 on the hoisting housing 1, the two hoisting housings 1 tend to approach each other, pressing the friction plate 605 against the top of the I-beam 7 to improve the stability between the hoisting housing 1 and the I-beam 7, prevent relative movement between the hoisting housing 1 and the I-beam 7, and improve the stability of hoisting.

[0030] Working principle: When in use, move the two hoisting shells 1 to the positions above the I-beam 7 and close to both ends of the I-beam 7 respectively, so that the clamping plates 303 are located on the front and back sides of the I-beam 7. Rotate the bidirectional lead screw 201 through the first handwheel 203. The bidirectional lead screw 201 drives the two moving plates 202 to approach each other. The moving plates 202 drive the support shell 301 to move. The support shell 301 drives the clamping plates 303 to approach each other, so that the two clamping plates 303 clamp the web of the I-beam 7. Then continue to make the two support shells 301 approach. At this time, the first slide rod 302, the clamping plate 303 and the extrusion block 304 do not move. Therefore, the first slide rod 302 will retract into the support shell 301, and the support shell 301 drives the fixed sleeve 501 to move, so that the first slide rod 302 will also retract into the fixed sleeve 501, and the spring 503 is compressed. At the same time, the support shell 301 drives the second slide rod 401 to move, so that the T-shaped slider 403 slides along the T-shaped groove 305, so that the upper and lower top pressing plates 402 move away from each other. Finally, the two top pressing plates 402 press against the upper and lower flange plates of the I-beam 7, so as to avoid the I-beam 7 from tilting relative to the clamping plate 303. Then rotate the unidirectional lead screw 602 through the second handwheel 606. The unidirectional lead screw 602 drives the lifting block 603 to move downwards, so that the friction plate 605 presses tightly on the top of the I-beam 7 to ensure the stability during hoisting.

[0031] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
