Description

Technical Field

[0001] This utility model relates to the field of hoisting and lifting tools, and more specifically, to a steel structure integral hoisting device. Background Technology

[0002] In fields such as building construction, bridge construction, and heavy machinery manufacturing, I-beams are widely used in steel structure systems due to their excellent cross-sectional mechanical properties, high bending strength, moderate flange width, and ease of connection. During the construction and installation of I-beam steel structures, overall hoisting is a crucial step, as the performance of the hoisting equipment directly affects construction efficiency, safety, and the integrity of the steel structure. For hoisting I-beam steel structures, I-beam clamps are typically used. These clamps connect the channel steel of the I-beam to the chains of the hoisting equipment, facilitating quick assembly and disassembly at the connection points.

[0003] Although existing I-beam clamps have many advantages, the distance between the I-beam clamping slots of their two clamping arms can only be adjusted by rotating a threaded rod to open and close the two clamping arms. While this adjustment method offers high precision and a wide range, it still requires slowly rotating the threaded rod to open the two clamping arms when quickly releasing or detaching the clamped I-beams. This makes it inconvenient for faster clamping and release of I-beams, affecting work efficiency. Therefore, we propose an integrated steel structure hoisting device to solve the above-mentioned problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a steel structure integral hoisting device. It further improves upon the existing adjustment assembly that can drive the opening and closing of clamping arms one and two. Stroke grooves are provided at both ends of the connecting shaft one of the adjustment assembly, and the stroke grooves are equipped with locking devices that can engage and limit the positions of the two ends of the connecting shaft one. When the two ends of the connecting shaft one are respectively engaged between the vertical surface of the locking device and one side of the inner wall of the stroke groove, a stable connection structure is formed between the connecting shaft one and clamping arms one. Rotating the threaded rod can drive the opening and closing of clamping arms one and two, facilitating the adjustment of the I-beam clamping slots one and two. The distance between the two I-beam clamping slots is increased, making it easier to clamp the I-beams and channel steel. When the clamping device is lifted by the wire rope, the two ends of the connecting shaft are not clamped between the vertical surface of the clamping device and one side of the inner wall of the travel groove. This allows the two ends of the connecting shaft to move back and forth in the travel groove in their own shape, forming an unstable connection structure between the connecting shaft and the clamping arm. This enables the clamping arm to open and close quickly relative to the clamping arm, thus allowing the distance between the I-beam clamping slots to increase rapidly. This facilitates the quicker disassembly and assembly of the I-beam clamping device and allows for easier clamping of the I-beams and channel steel. This further improves the efficiency of the I-beam clamping device and makes it more convenient to use.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A steel structure hoisting device includes a hanger, wherein hooks are connected to the four corners of the bottom of the hanger by iron chains, and each hook is detachably connected to an I-beam clamp.

[0009] The I-beam clamp includes a first clamp arm, a second clamp arm, and an adjustment assembly. The tops of the first clamp arm and the second clamp arm are rotatably connected by a lifting pin, and the lifting pin is detachably connected to the hook.

[0010] The clamping arm includes a set of clamping plates with identical structures. Each set of clamping plates has an I-beam clamping groove. The set of clamping plates is fixedly installed by a set of connecting pins. Each set of clamping plates located at the top of the I-beam clamping groove has a travel groove. Each set of clamping plates located on one side of the top of the travel groove has a rotating shaft fixedly welded to it. A clamping component is rotatably connected to the rotating shaft. The clamping component has a top surface, a vertical surface, and a slope surface. A torsion spring is also sleeved on the rotating shaft between the clamping component and the corresponding clamping plate. Each clamping plate has a locking hole. The two ends of the torsion spring are respectively locked inside the locking hole and on the top surface. The clamping component also has a through hole. The through holes of the set of clamping components are connected by a steel wire rope.

[0011] A positioning post is also fixedly welded to the clamping piece located at the top of the travel groove, and a slot is provided on the clamping piece corresponding to the position of the positioning post.

[0012] Furthermore, the clamping arm 2 includes a set of clamping plates 2 with the same structure, and each set of clamping plates 2 is provided with an I-beam clamping groove 2. The set of clamping plates 2 are fixedly installed together by a set of connecting pins 2.

[0013] Furthermore, the adjusting assembly includes a threaded rod, a first connecting shaft, and a second connecting shaft. The threaded rod has two threaded sections with opposite thread directions. The first connecting shaft and the second connecting shaft are threadedly connected to the two threaded sections respectively. A handle is fixedly installed at the end of the threaded rod. A set of clamping plates are each provided with a shaft hole. The two ends of the second connecting shaft are rotatably connected to the two shaft holes respectively. The two ends of the first connecting shaft are slidably connected to the two stroke grooves respectively.

[0014] Furthermore, both ends of the connecting shaft one and the connecting shaft two are provided with contact sections and anti-detachment sections. The outer diameter of the contact section, the inner diameter of the shaft hole, and the inner width of the stroke groove are all equal, and the length of the contact section on the connecting shaft one is greater than the length of the contact section on the connecting shaft two.

[0015] Furthermore, the length of the travel groove is greater than the length of the I-beam clamping groove.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] This solution further improves upon the existing adjustment assembly that can drive the opening and closing of clamping arms one and two. Stroke grooves are created at both ends of the connecting shaft one of the adjustment assembly, and these grooves are equipped with locking devices that can engage and limit the positions of both ends of the connecting shaft one. When both ends of the connecting shaft one are engaged between the vertical surface of the locking device and one side of the inner wall of the stroke groove, a stable connection structure is formed between the connecting shaft one and clamping arms one. Rotating the threaded rod can open and close clamping arms one and two, facilitating the adjustment of the distance between the I-beam clamping groove one and I-beam clamping groove two, thereby facilitating the clamping of I-beam channel steel. When the clamping device is lifted by the wire rope, both ends of the connecting shaft one are not clamped between the vertical surface of the clamping device and one side of the inner wall of the stroke groove. This allows both ends of the connecting shaft one to move back and forth within the stroke groove in their own shape, creating an unstable connection structure between the connecting shaft one and the clamping arm one. This enables the clamping arm one to open and close quickly relative to the clamping arm two, thereby rapidly increasing the distance between the I-beam clamping groove one and the I-beam clamping groove two. This facilitates faster disengagement and clamping of the I-beam clamping groove one and the I-beam clamping groove two onto the I-beam channel steel, further improving the disassembly and assembly efficiency of the I-beam clamp and making it convenient to use.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] Example 1:

[0035] Please see Figures 1-7 A steel structure hoisting device includes a hanger 1, with hooks 3 connected to the four corners of the bottom of the hanger 1 by iron chains 2, and each hook 3 is detachably connected to an I-beam clamp 4.

[0037] The clamping arm 5 includes a set of clamping plates 501 with identical structures, and each set of clamping plates 501 has an I-beam clamping groove 5011. The set of clamping plates 501 are fixedly installed together by a set of connecting pins 502. Each set of clamping plates 501 located at the top of the I-beam clamping groove 5011 has a travel groove 5012. Each set of clamping plates 501 located on one side of the top of the travel groove 5012 has a rotating shaft 503 fixedly welded to it. The rotating shaft 503 is rotatably connected to... There is a clamp 504, and the clamp 504 is provided with a top surface 5041, a vertical surface 5042 and a slope surface 5043. A torsion spring 505 is also sleeved on the rotating shaft 503 located between the clamp 504 and the corresponding clamp 501. The clamp 501 has a clamping hole. The two ends of the torsion spring 505 are respectively clamped in the clamping hole and the top surface 5041. The clamp 504 is also provided with a through hole 5044. A set of clamps 504 are connected by a steel wire rope 506.

[0038] A positioning post 5013 is also fixedly welded to the clip 501 at the top of the travel groove 5012, and a slot 5045 is provided on the clip 504 at the position corresponding to the positioning post 5013.

[0039] The clamping arm 2 6 includes a set of clamping plates 2 601 with the same structure, and each set of clamping plates 2 601 is provided with an I-beam clamping groove 2 6011. The set of clamping plates 2 601 are fixedly installed together by a set of connecting pins 2 602.

[0040] The adjusting assembly 7 includes a threaded rod 701, a first connecting shaft 702, and a second connecting shaft 703. The threaded rod 701 has two threaded sections 7011 with opposite thread directions. The first connecting shaft 702 and the second connecting shaft 703 are threadedly connected to the two threaded sections 7011 respectively. A handle is fixedly installed at the end of the threaded rod 701. A set of clamping plates 601 each has a shaft hole 6012. The two ends of the second connecting shaft 703 are rotatably connected to the two shaft holes 6012 respectively. The two ends of the first connecting shaft 702 are slidably connected to the two stroke grooves 5012 respectively.

[0041] Both ends of the connecting shaft 1 702 and the connecting shaft 2 703 are provided with a contact section 7021 and an anti-detachment section 7022. The outer diameter of the contact section 7021, the inner diameter of the shaft hole 6012, and the inner width of the stroke groove 5012 are all equal. The length of the contact section 7021 on the connecting shaft 1 702 is greater than the length of the contact section 7021 on the connecting shaft 2 703.

[0042] The length of the travel groove 5012 is greater than the length of the I-beam clamping groove 5011.

[0043] The operating principle of this type of steel structure hoisting device is as follows:

[0044] First, the contact sections 7021 at both ends of the connecting shaft 702 are respectively engaged between the inner wall of the travel groove 5012 and the vertical surface 5042 of the clamp 504, so that the two ends of the connecting shaft 702 and the connection position of a set of clamping plates 501 form a stable connection structure. At this time, by rotating the threaded rod 701, the distance between the connecting shaft 702 and the connecting shaft 703 can be increased or decreased, thereby causing the clamping arms 5 and 6 to open and close, controlling the distance between the I-beam clamping slots 5011 and 6011, so that the I-beam clamp 4 can be firmly clamped on the I-beam channel steel through the I-beam clamping slots 5011 and 6011. At this time, the crane can carry out the lifting operation of the clamped steel structure through the connection of its steel cable, the connection of the hanger 1, the iron chain 2 and the hook 3.

[0045] Once the steel structure is hoisted to its destination, there is no need to open the clamping arms 5 and 6 again by rotating the threaded rod 701. Simply lift the wire rope 506 upwards, causing one end of a set of clamps 504 on the clamping arm 5 to be lifted. The vertical surface 5042 will then disengage from the vertical intersection with the travel groove 5012. At this time, the contact sections 7021 at both ends of the connecting shaft 702 can be released from their position between the inner wall of the travel groove 5012 and the vertical surface 5042 of the clamp 504. Therefore, the two ends of the connecting shaft 702 can move freely back and forth inside the travel groove 5012, which makes it easier for the clamping arm 5 to be opened directly relative to the clamping arm 6. This directly increases the distance between the I-beam clamping groove 5011 and the I-beam clamping groove 6011, making it easier to remove the I-beam clamp 4 directly from the I-beam channel steel and improving the speed of removing the clamp.

[0046] Then, when it is necessary to clamp and hoist the next steel structure, simply place the clamping arm 5 in the open position relative to the clamping arm 6 at the clamping position of the I-beam and channel steel, and then forcefully push the clamping arm 5 relative to the clamping arm 6 back to the original position, forcing the clamping arm 5 and the clamping arm 6 back to the state of clamping the I-beam and channel steel. At this time, the distance between the I-beam clamping slot 1 5011 and the I-beam clamping slot 2 6011 returns to the smaller state, and clamps the I-beam and channel steel.

[0047] During the process of forcefully pushing clamp arm 5 relative to clamp arm 6 to reset, the contact sections 7021 at both ends of connecting shaft 702 can return to the position between the inner wall of stroke groove 5012 and the vertical surface 5042 of clamp 504 through the inclined surface 5043 of clamp 504, so that the connection of connecting shaft 702 forms a stable connection structure and avoids loosening during the subsequent lifting process.

[0048] Example 2:

[0049] In view of the above embodiment 1, further description is provided, see reference. Figures 6-7 The torsion spring 505 provides downward pressure to the clamp 504, so that when the wire rope 506 is released and pulled, the vertical surface 5042 of the clamp 504 can automatically return to a state that is perpendicular to the travel groove 5012, which makes it easy to firmly clamp the contact sections 7021 at both ends of the connecting shaft 702 at the position between the inner wall of the travel groove 5012 and the vertical surface 5042 of the clamp 504.

[0050] The ramp surface 5043 is designed to facilitate the reverse movement and reset of the contact sections 7021 at both ends of the connecting shaft 702. It can directly pass over the ramp surface 5043 and be locked between the inner wall of the stroke groove 5012 and the vertical surface 5042 of the clamp 504, improving the convenience of resetting the clamping arm 5 and eliminating the need to rotate the threaded rod 701 for resetting.

[0051] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
