Description

Technical Field

[0001] This application relates to the field of construction, and more particularly to a clamping mechanism for suspending steel beams. Background Technology

[0002] During the construction of the steel structure of the factory building, steel beams need to be hoisted. When hoisting the steel beams, a clamping mechanism is required to clamp and fix them. However, the existing clamping mechanism has many inconveniences when clamping the steel beams.

[0003] Chinese patent CN114348861A discloses a rebar hoisting and clamping device for construction engineering, including a main hoisting sleeve installed on top of a first base. A double-hoop sleeve for limiting connection is fixedly connected inside the first base. An extension arm for limiting extension is fixedly connected inside the double-hoop sleeve. An adjustable support frame is sleeved inside the extension arm. A second base for supporting an auxiliary hoisting sleeve is fixedly connected to one end of the support frame. This rebar hoisting and clamping device, through the arrangement of the main hoisting sleeve, auxiliary hoisting sleeve, extension arm, and support frame, allows for adjustable spacing between the main and auxiliary hoisting sleeves via the extension arm and support frame. The adjusted spacing between the main and auxiliary hoisting sleeves can accommodate the force area of ​​rebars of different lengths during hoisting and clamping, thereby reducing excessive angular swaying of the rebars during handling.

[0004] Patent CN111453605A discloses a steel structure hoisting structure for an incineration plant, including a lifting ring, a lifting plate, load-bearing chains, anti-winding struts, connecting components, a horizontal beam frame, a vertical beam frame, a first lifting chain, a hoisting component, a second lifting chain, and a positioning component. A lifting ring is welded and fixedly installed at the center of the top end face of the lifting plate. Load-bearing chains are connected and installed around the four sides of the bottom end face of the lifting plate. Connecting components are provided at the bottom of the load-bearing chains, and a horizontal beam frame and a vertical beam frame are arranged between the connecting components. The first lifting chain is fixedly installed on both sides of the bottom end face of the horizontal beam frame, and a hoisting component is provided at the bottom of the first lifting chain. This steel structure hoisting structure for the incineration plant is simple in structure and safe to use. During hoisting, the steel structure is clamped and secured, providing a firm fixation effect and limiting the position of the steel structure, resulting in stable hoisting and effectively reducing the swaying of the steel structure during hoisting.

[0005] Patent CN108002289A discloses a steel structure hoisting frame, including a hoisting rod, a lifting rod, a fixing rod, a lifting device, and a base. A support rod is provided on one side of the hoisting rod, and a fixing nut is provided between the hoisting rod and the support rod. A fixing rod is provided between the support rod and the hoisting rod. The fixing rod, support rod, and hoisting rod form a triangle. Multiple lifting rings are provided on the hoisting rod. A rotating rod is provided on one side of the support rod, and the rotating rod is fixedly connected to the support rod. A lifting rod is provided on one side of the rotating rod, and a lifting rod is provided on one side of the lifting rod, and the lifting rod is fixedly connected to the lifting rod. A lifting device is provided on one side of the lifting rod, and a base is provided on one side of the lifting device, and the lifting device is fixedly connected to the base. This steel structure hoisting frame, with the fixing rod, support rod, and hoisting rod forming a triangle, facilitates better fixation of the hoisting rod, contributing to a more stable operation of the hoisting frame.

[0006] Therefore, existing clamping mechanisms are generally fixed to hoisting equipment during installation. While they provide stability, they require waiting for the hoisting equipment to return and unload the steel beams before they can be clamped and assembled again. This slows down construction if too many steel beams need to be hoisted, and also requires additional personnel to wait, increasing manpower consumption. Furthermore, they lack flexibility and guidance during descent. After hoisting, the steel beams need accurate positioning before being lowered, requiring constant communication between the personnel below and those operating the hoisting equipment. If the personnel below have an obstructed view, the beam's descent position becomes uncertain. If the descent is near the edge, the risk of the beam falling increases, making them impractical.

[0031] Example:

[0032] Please refer to Figure 1 (Refer to) Figures 2 to 5This application provides a clamping mechanism for suspending steel beams, including two sets of positioning components. The two sets of positioning components are respectively clamped to both ends of the steel beam, and each set of positioning components has a shackle 1 installed on its top, and a steel wire rope 2 connected to the shackle 1. At the same time, a fixed seat 3 is welded to the two opposite outer walls of each set of positioning components. Each fixed seat 3 is vertically connected to a first adjusting bolt 4 that passes through the top and bottom. The bottom end of the first adjusting bolt 4 is rotatably connected to a base plate 5. The bottom of each base plate 5 is angularly connected to a guide plate 6.

[0033] Furthermore, each positioning assembly includes two clamping plates 7; wherein the two clamping plates 7 are respectively clamped to the opposite outer sides of one end of the steel beam, and one end of one clamping plate 7 is detachably connected to one end of the other clamping plate 7 by a locking bolt 8 and a shackle 1; and the locking bolt 8 is sequentially threaded to the front end of the shackle 1, one end of one clamping plate 7, one end of the other clamping plate 7, and the rear end of the shackle 1.

[0034] It should be noted that the clamping plate 7 includes a top plate 9, a vertical connecting plate 10, and a bottom plate 11 connected vertically in sequence. The top plate 9, the vertical connecting plate 10, and the bottom plate 11 together form a clamping groove for clamping onto the steel beam. The top plate 9 and the bottom plate 11 are arranged parallel to each other on the same side of the vertical connecting plate 10, and the length of the top plate 9 is greater than the length of the bottom plate 11. The top plate 9 has a connecting through hole 12 that mates with the locking bolt 8, and both ends of the top of the top plate 9 have oblique notches. The bottom of the bottom plate 11 has an installation groove, inside which a clamping plate 13 is installed. The bottom of the clamping plate 13 is rotatably connected to a second adjusting bolt 14 via a bearing. The second adjusting bolt 14 passes through the bottom of the bottom plate 11 and is threadedly connected to the bottom plate 11.

[0035] Furthermore, the two guide plates 6 are arranged in a V-shape; a fixing plate 15 is welded to the top of the guide plate 6, and the fixing plate 15 is bolted to the base plate 5 by multiple screws. In addition, guide seats 16 are welded to opposite sides of the fixing seat 3, and two guide rods 17 are welded to the top of the base plate 5. The top of the guide rods 17 passes through and extends to the top of the guide seat 16, and the guide seat 16 has a guide groove inside that cooperates with the guide rods 17.

[0036] Therefore, in use, a set of clamping plates 7 are first clamped onto both sides of the steel beam. After clamping, one end of the wire rope 2 is looped onto the shackle 1, and both ends of the shackle 1 are located outside the two clamping plates 7. Then, the threaded end of the locking bolt 8 is passed through the front end of the shackle 1, the two connecting through holes 12 and the rear end of the shackle 1 in sequence and tightened. After one set is assembled, the other set of positioning components is assembled in the same way. Then, the other ends of the two wire ropes 2 are looped onto the hook of the hoisting equipment, which can achieve clamping of the steel beam. It is easy to operate and has good stability. The whole adopts a prefabricated installation connection, thus improving the convenience of the mechanism and reducing the production cost.

[0037] After the steel beam is hoisted to a certain distance from the ground, the workers approach and hold the first adjusting bolt 4 to rotate it. When the first adjusting bolt 4 rotates, it will rotate downwards with the cooperation of the fixed seat 3. When the first adjusting bolt 4 rotates downwards, it will drive the base plate 5 downwards with the cooperation of the bearing, guide rod 17 and guide seat 16. When the base plate 5 moves downwards, it will drive the corresponding guide plate 6 to move downwards together. It can provide guidance during the descent, improve the safety of the steel beam during descent, reduce personnel consumption, and has high practicality.

[0038] In summary, the clamping mechanism for lifting steel beams in this application is convenient and stable, and the overall assembly and installation connection improves the convenience of the mechanism. At the same time, the production cost is low, and it can also guide the steel beam during the descent, which improves the safety of the steel beam during descent, reduces personnel consumption, and has high practicality.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
