Description

Technical Field

[0001] This utility model belongs to the field of steel component hoisting technology, specifically, it relates to a steel component hoisting device. Background Technology

[0002] Steel components refer to steel structural composite components that can bear and transmit loads, made of steel plates, angle steel, channel steel, I-beams, welded or hot-rolled H-beams that are cold-bent or welded and connected by connectors. They are widely used in the construction industry, and steel components need to be hoisted during construction.

[0003] When hoisting existing steel components, lifting rings are usually pre-welded onto the steel components, and then the hooks or ropes of the lifting equipment are connected to the lifting rings before the hoisting operation. This method has certain problems in actual operation. For example, the welded lifting rings need to be cut after hoisting, and the welded parts of the lifting rings need to be ground. After grinding, anti-corrosion or other coatings need to be applied. This method involves many steps, is relatively cumbersome, and has high labor intensity and low efficiency in the later stages.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies.

[0005] Therefore, in order to solve the above problems, this utility model provides a steel component hoisting device. Utility Model Content

[0006] To overcome the aforementioned technical problems, the purpose of this utility model is to provide a steel component hoisting device. First, four sets of hoisting seats are respectively clamped at both ends of the steel component. Then, the movable plate is moved downward so that it presses against the top of the steel component. By connecting the hook or rope of the lifting equipment to the lifting ring, the steel component is hoisted. After being hoisted to the designated position, the hoisting seats are pushed out from under the steel component by the action of the jack.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A steel component hoisting device includes a steel component and hoisting seats. The hoisting seats consist of four sets, evenly distributed on both sides of the steel component. Each hoisting seat is connected to a movable plate that can be adjusted in position. A lifting ring is installed on one side of the top of each hoisting seat. A push-out assembly, including a jack, is connected between two sets of hoisting seats in the X-axis direction. First, the four sets of hoisting seats are respectively locked at both ends of the steel component. Then, the movable plate is moved downward so that it presses against the top of the steel component. By connecting the hook or rope of the lifting equipment to the lifting ring, the steel component is hoisted. After being hoisted to the designated position, the hoisting seats are pushed out from under the steel component by the action of the jack.

[0009] Furthermore, a screw is threadedly connected to the hoisting base, the bottom end of the screw is connected to the movable plate, and a handle is fixedly installed at the top end of the screw.

[0010] Furthermore, multiple sets of limiting grooves are provided at the top edge of the rotating handle, and a mounting seat is provided at the top of the hoisting seat. A limiting rod is rotatably connected to the mounting seat, and one end of the limiting rod matches the limiting groove.

[0011] Furthermore, the movable plate is provided with insertion holes.

[0012] Furthermore, a connecting rod is connected between the two sets of the lifting seats in the Y-axis direction, and the two ends of the connecting rod are respectively inserted into the corresponding holes.

[0013] Furthermore, the ejection assembly also includes a crossbeam, with both ends of the crossbeam connected to the corresponding lifting bases, the jack connected to the inner side of the crossbeam, and the output end of the jack connected to a top plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, four sets of lifting seats are first secured to both ends of the steel component. Then, the handle is rotated, causing the screw to rotate. The rotation of the screw causes the movable plate to move downwards, pressing it against the top of the steel component. Next, the limiting rod is rotated around the mounting base, causing one end to engage in the corresponding limiting groove, thus limiting the handle and consequently the movable plate. Then, both ends of the connecting rod are inserted into the corresponding holes on the movable plate, further limiting the lifting seats. The lifting equipment's hook or rope is connected to the lifting ring, and then the steel component is lifted. After being lifted to the designated position, the lifting seat is pushed out from under the steel component by the action of the jack. Because the overall weight of the steel component is relatively heavy, the jack will not push the steel component to move after it is lifted to the designated position. Since the steel component is stationary, the crossbar is subjected to a counter-push force, which can push the lifting seat out from under the steel component. The top plate can increase the contact area between the jack and the steel component, avoiding squeezing and deforming the steel component. Attached Figure Description

[0023] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0024] Please see Figure 1-4 According to an embodiment of the present invention, a steel component hoisting device includes a steel component 1 and a hoisting seat 2. The hoisting seat 2 includes four sets, which are evenly distributed on both sides of the steel component 1. A movable plate 201 capable of position adjustment is connected to the hoisting seat 2. A lifting ring 208 is installed on one side of the top of the hoisting seat 2. A push-out assembly 4 is connected between two sets of hoisting seats 2 in the X-axis direction. The push-out assembly 4 includes a jack 402. First, the four sets of hoisting seats 2 are respectively locked at both ends of the steel component 1. Then, the movable plate 201 is moved downward so that the movable plate 201 is pressed against the top of the steel component 1. By connecting the hook or rope of the lifting equipment to the lifting ring 208, the steel component 1 is hoisted. After being hoisted to the designated position, the hoisting seat 2 is pushed out from under the steel component 1 by the action of the jack 402.

[0025] A screw rod 202 is threadedly connected to the lifting base 2. The bottom end of the screw rod 202 is connected to the movable plate 201, and a handle 203 is fixedly installed on the top end of the screw rod 202.

[0026] Multiple sets of limiting grooves 204 are provided at the top edge of the rotating handle 203. The top end of the lifting base 2 is connected to the mounting base 205. A limiting rod 206 is rotatably connected to the mounting base 205. One end of the limiting rod 206 matches the limiting groove 204.

[0027] The movable plate 201 has an insertion hole 207.

[0028] A connecting rod 3 is connected between the two sets of lifting seats 2 in the Y-axis direction, and the two ends of the connecting rod 3 are respectively inserted into the corresponding insertion holes 207.

[0029] The ejector assembly 4 also includes a crossbeam 401, with both ends of the crossbeam 401 connected to the corresponding lifting base 2. A jack 402 is connected to the inner side of the crossbeam 401, and the output end of the jack 402 is connected to the top plate 403.

[0030] The working principle of the steel component hoisting device of this utility model patent is as follows: First, four sets of hoisting seats 2 are respectively clamped at both ends of the steel component 1. Then, the handle 203 is rotated, which drives the screw 202 to rotate. The rotation of the screw 202 drives the movable plate 201 to move downward, so that the movable plate 201 is pressed against the top of the steel component 1. Then, the limiting rod 206 is rotated around the mounting base 205, so that one end of it is clamped in the limiting groove 204 at the corresponding position, thereby completing the limiting of the handle 203 and thus the limiting of the movable plate 201. Then, the two ends of the connecting rod 3 are respectively inserted into the insertion holes 207 on the movable plate 201 at the corresponding positions, further... The lifting seat 2 is limited by the lifting equipment hook or rope connected to the lifting ring 208, and the steel component 1 is lifted. After being lifted to the designated position, the lifting seat 2 is pushed out from under the steel component 1 by the action of the jack 402. Since the overall weight of the steel component 1 is relatively heavy, the jack 402 will not push the steel component 1 to move after it is lifted to the designated position. Since the steel component 1 is stationary, the cross frame 401 is subjected to a counter-thrust force, which can push the lifting seat 2 out from under the steel component 1. The top plate 403 can increase the contact area between the jack 402 and the steel component 1 to avoid squeezing and deforming the steel component 1.
