Description

Technical Field

[0001] A steel beam hoisting and clamping device is used for hoisting steel beams, belonging to the technical field of steel beam hoisting and clamping devices. Background Technology

[0002] In factory construction, steel structures are widely used due to their high strength, light weight, fast construction speed, and good seismic performance. H-beams and cross-beams are common steel structure forms, and their hoisting and installation is a crucial step in the construction process. Hoisting operations not only directly affect project quality and progress but also construction safety. Therefore, selecting a suitable hoisting and clamping structure is essential for steel structure construction. Although steel structure hoisting technology is relatively mature, employing hooks or binding ropes for hoisting and clamping steel structures, the following technical problems still exist in practical applications:

[0003] 1. When using hooks to hoist steel structures, there are high requirements for the shape and size of the steel structure;

[0004] 2. When steel structures are hoisted using binding ropes, the binding ropes, as the direct load-bearing components, are prone to wear and breakage, which can lead to the steel structure falling off and poses a significant safety hazard. Utility Model Content

[0005] The purpose of this utility model is to provide a steel beam hoisting and clamping device to solve the problem that the existing technology of using hooks to hoist steel structures has high requirements on the shape and size of the steel structure; when using binding ropes to hoist steel structures, the binding ropes, as the direct force-bearing components, are prone to wear and breakage, which can lead to the steel structure falling off and poses a significant safety hazard.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A steel beam hoisting clamping device includes a hard clamping structure connected to a hoisting rope and having an adjustable clamping spacing for clamping the steel structure, and a soft clamping structure disposed on the hard clamping structure for clamping and fixing the hard clamping structure.

[0008] Furthermore, the rigid clamping structure includes a horizontal connecting beam with a sliding groove, an L-shaped clamping block A fixedly mounted on one end of the horizontal connecting beam, an L-shaped clamping member that cooperates with the L-shaped clamping block A to clamp the steel structure, a fixing block with its upper surface at the same level as the upper surface of the L-shaped clamping member being provided on the upper surface of the horizontal connecting beam, a hanging ring connected to the suspension rope being provided on the fixing block and the L-shaped clamping member respectively, and a fixing member that cooperates with the soft clamping structure being provided on the L-shaped clamping block A and the L-shaped clamping member respectively.

[0009] Furthermore, the L-shaped clamping member includes a T-shaped block slidably disposed in the slide groove, and an L-shaped clamping block B disposed on the T-shaped block at one end of the bottom of the transverse connecting beam, which cooperates with the L-shaped clamping block A to clamp the steel structure.

[0010] Furthermore, the fastener includes a mounting block with a through hole on one side of the top edge of the vertical plate of L-shaped clamp A and L-shaped clamp B, a hanger on the outside of the vertical plate, and a U-shaped cavity on the bottom of the horizontal plate of L-shaped clamp A and L-shaped clamp B.

[0011] The mounting block on L-shaped clamp A is on the same side as the U-shaped cavity and hanger on L-shaped clamp B, and the mounting block on L-shaped clamp B is on the same side as the U-shaped cavity and hanger on L-shaped clamp A.

[0012] Furthermore, the soft clamping structure includes a binding strap on the mounting blocks of L-shaped clamp A and L-shaped clamp B, and a shaping hose on the binding strap at the other end of the mounting block for passing through the U-shaped cavity. Multiple hanging holes are provided on the binding strap to cooperate with the screw. The binding straps on L-shaped clamp A and L-shaped clamp B cooperate with the U-shaped cavity and hanging piece on L-shaped clamp B and L-shaped clamp A, respectively.

[0013] Furthermore, the hanging component includes a screw rod disposed on the outer side of the vertical plate of L-shaped clamp A and L-shaped clamp B, and a nut disposed on the screw rod for fixing the binding strap.

[0014] Furthermore, on one side of the L-shaped clamping member, a threaded hole communicating with the slide groove is provided on the transverse connecting beam, and a bolt for sliding and limiting the L-shaped clamping member is provided on the threaded hole.

[0015] Furthermore, grooves are provided on the upper surface of the horizontal plates of the L-shaped clamping blocks A and B, and rollers parallel to the vertical plates are rotatably arranged in the grooves, with the rollers being higher than the top of the grooves.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] I. This utility model sets up a hard clamping structure that directly contacts the steel, and uses a soft clamping structure to clamp and fix the hard clamping structure. The hard clamping structure can be adjusted in clamping distance and serves as a direct contact and force-bearing structure. This can effectively avoid the high requirements on the shape and size of the steel structure when using hooks to hoist the steel structure. At the same time, it avoids the problem that when using binding ropes to hoist the steel structure, the binding ropes, as direct force-bearing components, are prone to wear and breakage, which can lead to the steel structure falling off and pose a significant safety hazard.

[0018] II. The rigid clamping structure in this utility model fixes the L-shaped clamp A on the horizontal connecting beam and allows the L-shaped clamping member to slide closer to or further away from the L-shaped clamp A on the horizontal connecting beam. This not only facilitates the hoisting of steel structures of different shapes and sizes, but also ensures that the L-shaped clamp A and the L-shaped clamping member are evenly stressed during hoisting by cooperating with the hanging rings and hoisting ropes provided on the L-shaped clamp A and the L-shaped clamping member. This also ensures the stability of the steel structure during hoisting. Furthermore, the combination of the fixed structure and the soft clamping structure effectively ensures the stability of the soft clamping structure when fixing the rigid clamping structure.

[0019] Third, the L-shaped clamping component in this utility model uses the sliding cooperation between the T-shaped block and the slide groove to drive the L-shaped clamping block B and the L-shaped clamping block A to clamp or release the steel structure, which is convenient to operate and easy to cooperate with the steel structure.

[0020] IV. In this utility model, the fixing component is installed with a soft clamping structure via an mounting block. The soft clamping structure is positioned by a U-shaped cavity on the opposite side, and the soft clamping structure is fixed by a hanger on the side of the U-shaped cavity. This ensures that the soft clamping structure can quickly and effectively fix L-shaped clamping blocks A and B to a specified size, further ensuring the stability of the steel structure clamped by the hard clamping structure. The mounting block on L-shaped clamping block A is on the same side as the U-shaped cavity and hanger on L-shaped clamping block B, and the mounting block on L-shaped clamping block B is on the same side as the U-shaped cavity and hanger on L-shaped clamping block A. This is to facilitate double fixing and also to avoid the problem of difficulty in fixing.

[0021] V. The soft clamping structure in this utility model uses a shaped flexible tube to pass through the U-shaped cavity, which facilitates the quick passage of the binding strap through the U-shaped cavity to cooperate with the hanging part, making the operation convenient and fast;

[0022] VI. The hanging component in this utility model includes a screw and a nut, which facilitates the fixing of the binding strap hanging on the screw with the nut to prevent the binding strap from slipping off;

[0023] VII. This utility model provides threaded holes on the transverse connecting beam of the L-shaped clamping component, and threads bolts on the threaded holes to limit the L-shaped clamping component, further ensuring the stability of the rigid clamping structure in clamping the steel structure and effectively avoiding the problem of falling off.

[0024] 8. In this utility model, grooves are provided on L-shaped clamping blocks A and B, and rollers are rotatably arranged in the grooves. The rollers are higher than the top of the grooves. The purpose is to facilitate placing the horizontal plates of L-shaped clamping blocks A and B under the steel structure or under the clamping position, or to remove them after hoisting them to the designated position.

[0039] Example 1

[0040] To address the issue that existing technologies using hooks for steel structure hoisting have stringent requirements regarding the shape and dimensions of the steel structure, and that using binding ropes for hoisting presents a significant safety hazard due to the binding ropes being direct load-bearing components and prone to wear and breakage, leading to steel structure detachment. Figure 1-5 The diagram illustrates a steel beam hoisting clamping device, comprising a rigid clamping structure 2 connected to a hoisting rope 1 and having an adjustable clamping spacing for clamping the steel structure, and a soft clamping structure 3 disposed on the rigid clamping structure 2 to clamp and fix the rigid clamping structure 2. During hoisting, at least one of these clamping devices is required, and typically two are used.

[0041] In practice, when hoisting H-beams, the rigid clamping structure 2 can be adjusted to clamp the bottom of the H-beam, and then the rigid clamping structure 3 can be used to fix the rigid clamping structure 2. This allows the hoisting rope to be used in conjunction with a crane or other equipment for hoisting. This embodiment uses a rigid clamping structure that directly contacts the steel, and a soft clamping structure to hold and fix the rigid clamping structure. The rigid clamping structure, with its adjustable clamping spacing, serves as the direct contact and load-bearing structure. This effectively avoids the high requirements on the shape and size of the steel structure when using hooks for hoisting, and also avoids the safety hazards associated with using binding ropes, where the binding ropes, as direct load-bearing components, are prone to wear and breakage, leading to the steel structure falling off.

[0042] Example 2

[0043] Based on embodiment 1, the rigid clamping structure 2 includes a horizontal connecting beam 5 with a sliding groove 4, an L-shaped clamping block A6 fixedly installed on one end of the horizontal connecting beam 5, an L-shaped clamping member 7 that cooperates with the L-shaped clamping block A6 to clamp the steel structure, a fixing block 8 with its upper surface at the same level as the upper surface of the L-shaped clamping member 7 on the upper surface of the horizontal connecting beam 5, a hanging ring 9 connected to the suspension rope 1 on the fixing block 8 and the L-shaped clamping member 7 respectively, and a fixing member that cooperates with the soft clamping structure 3 on the L-shaped clamping block A6 and the L-shaped clamping member 7 respectively. The rigid clamping structure, by fixing L-shaped clamp A to the transverse connecting beam and using L-shaped clamping members to slide closer to or further away from L-shaped clamp A on the transverse connecting beam, not only facilitates the hoisting of steel structures of different shapes and sizes, but also, through the cooperation of the hanging rings on L-shaped clamp A and L-shaped clamping members with the hoisting rope, effectively ensures uniform force distribution on L-shaped clamp A and L-shaped clamping members during hoisting and guarantees the stability of the steel structure during hoisting. Furthermore, the combination of the fixed structure and the soft clamping structure effectively ensures the stability of the soft clamping structure when fixing the rigid clamping structure.

[0044] The L-shaped clamping member 7 includes a T-shaped block 10 slidably disposed in the slide groove 4, and an L-shaped clamping block B11 disposed on the T-shaped block 10 at one bottom end of the transverse connecting beam 5, which cooperates with the L-shaped clamping block A6 to clamp the steel structure. The L-shaped clamping member drives the L-shaped clamping block B and the L-shaped clamping block A to clamp or release the steel structure through the sliding cooperation between the T-shaped block and the slide groove. It is easy to operate and facilitates cooperation with the steel structure.

[0045] The fasteners include a mounting block 13 with a through hole 12 on one side of the top edge of the vertical plate of L-shaped clamp A6 and L-shaped clamp B11, a hanger on the outside of the vertical plate, and a U-shaped cavity 14 on the bottom of the horizontal plate of L-shaped clamp A6 and L-shaped clamp B11. The mounting block 13 on L-shaped clamp A6 is on the same side as the U-shaped cavity 14 and the hanger on L-shaped clamp B11. The mounting block 13 on L-shaped clamp B11 is on the same side as the U-shaped cavity 14 and the hanger on L-shaped clamp A6. The fasteners install the soft clamping structure via mounting blocks. The soft clamping structure is positioned by U-shaped cavities on opposite sides, and is fixed by hangers on the U-shaped cavity side. This ensures that the soft clamping structure quickly and effectively fixes L-shaped clamping blocks A and B to the specified size, further guaranteeing the stability of the steel structure clamped by the hard clamping structure. The mounting block on L-shaped clamping block A is on the same side as the U-shaped cavity and hanger on L-shaped clamping block B, and the mounting block on L-shaped clamping block B is on the same side as the U-shaped cavity and hanger on L-shaped clamping block A. This is to facilitate double fixing and also to avoid problems with difficult fixing.

[0046] The soft clamping structure includes a binding strap 15 on a mounting block 13 on L-shaped clamping blocks A6 and B11, and a shaped flexible tube 16 on the binding strap 15 at the other end of the mounting block 13 for passing through a U-shaped cavity 14. Multiple hanging holes 23 are provided on the binding strap 15 to mate with a screw. The binding straps 15 on L-shaped clamping blocks A6 and B11 respectively mate with the U-shaped cavity 14 and the hanger on L-shaped clamping blocks B11 and A6. The length of the U-shaped cavity 14 and its position along the length of the bottom of the horizontal plate are selected according to actual needs. The soft clamping structure, with the shaped flexible tube passing through the U-shaped cavity, facilitates the quick and easy passage of the binding strap through the U-shaped cavity to mate with the hanger, making operation convenient and fast. The shaped flexible tube is also easy to bend and retract.

[0047] The hanging device includes a screw 17 mounted on the outer side of the vertical plates of L-shaped clamp A6 and L-shaped clamp B11, and a nut 18 mounted on the screw 17 for securing the cable tie 15. The hanging device includes a screw and a nut, which facilitates securing the cable tie hanging on the screw with the nut to prevent it from slipping off.

[0048] In practice, when steel structure hoisting is required, first place the L-shaped clamp A6 at the bottom of the steel structure or at the designated position. Then, adjust the T-shaped block 10 to slide and engage with the slide groove 4 to drive the L-shaped clamp B11 to slide towards the L-shaped clamp A6 and place it at the bottom of the steel structure or at the designated position. Then, the shaped flexible hose 16 set on the binding strap 15 on the L-shaped clamp A6 and L-shaped clamp B11 respectively passes through the U-shaped cavity 14 on the L-shaped clamp B11 and L-shaped clamp A6, and tighten the binding strap. The hanging hole 23 on the binding strap is hung on the screw 17 on the side of the U-shaped cavity 14, and the binding strap is fixed to the screw 17 by the cooperation of the nut 18 with the screw 17, so that the L-shaped clamp A6 and L-shaped clamp B11 are in the state of clamping the steel structure before hoisting. Conversely, after the steel structure is hoisted to the designated position, the L-shaped clamps A6 and B11 of the binding straps can be removed to remove the rigid clamp structure from the steel structure.

[0049] Example 3

[0050] Based on Embodiment 2, a threaded hole 19 communicating with the slide groove 4 is provided on the transverse connecting beam 5 on one side of the L-shaped clamping member 7. A bolt 20 is provided on the threaded hole 19 to limit the sliding of the L-shaped clamping member 7. The bolt 20 moves towards the L-shaped clamping block A6 to limit the sliding range of the L-shaped clamping member 7; conversely, it cancels the limitation. The threaded hole on the transverse connecting beam of the L-shaped clamping member, and the bolt threaded on the threaded hole to limit or cancel the limitation of the L-shaped clamping member, further ensures the stability of the rigid clamping structure in clamping the steel structure and effectively avoids the problem of falling off.

[0051] Example 4

[0052] Based on embodiment 3, grooves 21 are provided on the upper surface of the horizontal plates of the L-shaped clamping blocks A6 and B11. A roller 22, parallel to the vertical plate, is rotatably disposed within the groove 21, and the roller 22 is higher than the top of the groove 21. The purpose of providing grooves on L-shaped clamping blocks A and B, with rollers rotatably disposed within the grooves and higher than the top of the grooves, is to facilitate placing the horizontal plates of L-shaped clamping blocks A and B under the steel structure or in the clamping position, or for removal after hoisting to a designated position.
