Description

Technical Field

[0001] This utility model relates to the field of H-beam clamping technology, and in particular to a multi-purpose clamping fixture for H-beams. Background Technology

[0002] H-beams, as a type of steel with excellent cross-sectional mechanical properties and strong load-bearing capacity, have been widely used in construction engineering, bridge construction, industrial plant construction and other fields. During their installation, splicing and welding, special clamps are required to achieve precise positioning and stable clamping in order to ensure construction quality and work safety. The existing method for hoisting H-shaped steel beams mostly involves welding lifting lugs to both ends of the steel beam as lifting points. This method requires the lugs to be cut off after the steel beam is in place, which results in material waste and potential damage to the steel beam itself. If the steel beam needs to be used temporarily during construction, the lugs can only be welded to the bottom of the steel beam as lifting points, which will cause some damage to the steel beam. Therefore, improvements are needed to address these issues. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-purpose clamp for H-beams.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a multi-purpose clamp for H-beams, comprising two mating blocks that fit and conform to the sides, top surface, and bottom surface of the H-beam flange. Symmetrical telescopic grooves are formed on the upper surfaces of the opposing sides of the two mating blocks. Extension plates are slidably installed within the telescopic grooves. Limiting blocks are provided at the opposing ends of the two extension plates. The opposite ends of the two extension plates extend beyond the outer wall of the mating blocks through the telescopic grooves. Thick steel plates are welded to the mating surfaces of the mating blocks. Two triangular plates are symmetrically welded at the included angle of the outer walls of the two mating blocks. Slots are formed on both sides of the telescopic grooves on the outer walls of the mating blocks. Fixing plates are inserted into the slots. Two mounting blocks are symmetrically provided on the lower ends of one side of each of the two mating blocks. Mounting grooves are formed on the opposing surfaces of the two mounting blocks, and detection components are installed within the mounting grooves.

[0005] Preferably, the lower ends of the opposite surfaces of the two bonding blocks are provided with fixing bolts for fixing the two bonding blocks together, and the two bonding blocks have two symmetrical lifting holes at the lower ends of the fixing bolts.

[0006] Preferably, the extension plate has multiple limiting holes equidistantly opened on both sides, the outer wall of one side of the fixing plate has multiple connecting posts equidistantly provided to match the limiting holes, the top surface of the fixing plate has two connecting holes symmetrically opened, the top surface of the fitting block has a fixing hole coaxial with the connecting hole, and a locking bolt is screwed between the fixing hole and the connecting hole.

[0007] Preferably, the top surface of the extension plate has multiple rows of bolt holes at equal intervals, and the inner top surface of the thick steel plate has multiple through holes coaxial with the bolt holes. An abutment bolt is screwed into the bolt hole, and one end of the abutment bolt passes through the through hole and abuts against the flange of the H-beam.

[0008] Preferably, the detection component includes movable blocks slidably disposed in two mounting slots. A sleeve and a telescopic sleeve are respectively provided on the opposite surfaces of the two movable blocks. A fixed sleeve is fitted onto the telescopic end of the telescopic sleeve. A locking bolt is screwed between the telescopic end of the telescopic sleeve and the fixed sleeve. A battery box is fixedly connected to the opposite surface of the fixed sleeve and the sleeve. One end of the battery box extends into the sleeve and is equipped with a pressure sensor. The force-receiving end of the pressure sensor abuts against a spring.

[0009] Preferably, both mounting blocks are screwed with screw-in bolts at opposite ends, and one end of the screw-in bolt is screwed to the movable block.

[0010] Compared with existing technologies, the advantages of this utility model are as follows: This utility model, through the cooperation of the bonding block and the thick steel plate, can tightly fit the sides, top, and bottom surfaces of the H-beam flange. Combined with the symmetrically opened lifting holes at the lower end of the bonding block, it serves as a stable interface for clamps, slings, lifting rings, and other lifting connectors. This eliminates the need for welding lifting lugs, forming a uniformly stressed lifting structure, facilitating rapid assembly of the lifting system. It avoids the tedious steps of additional processing of the lifting structure and ensures uniform weight distribution of the H-beam during lifting, thus improving the efficiency of lifting preparation. The convenience, efficiency, and stability of the hoisting process enable non-destructive hoisting of H-beams. Furthermore, the sliding cooperation between the extension plate and the telescopic slot, combined with the fixing plate and locking bolts, allows for flexible adjustment of the extension plate's extension length, facilitating the adaptation of H-beam flanges of different widths and improving the clamp's adaptability. This enables universal hoisting of H-beams of various specifications. Ultimately, this solves the problems of existing H-beam hoisting methods that require welding lifting lugs, resulting in material waste and easy damage to the steel beams, thus improving the safety and economy of H-beam hoisting.

[0016] Working Principle: When using the multi-purpose clamp for H-beams of this utility model, before hoisting, the clamp must be adjusted to fit the width of the H-beam flange: First, loosen the locking bolt on the top surface of the mating block 1, pull out the fixing piece 4 in the slot so that the connecting post 6 on it is disengaged from the limiting hole of the extension plate 2, and then slide the extension plate 2 along the telescopic groove 9 on the upper surface of the mating block 1 until the extension plate 2 and the mating block 1 together cover the width of the flange to be clamped; then, reinsert the fixing piece 4 into the slot so that the connecting post 6 is aligned with the limiting hole at the corresponding position of the extension plate 2, tighten the locking bolt so that it passes through the connecting hole on the top surface of the fixing piece 4 and screws it into the fixing hole 7 on the top surface of the mating block 1, thus locking the position of the extension plate 2 and realizing the adaptation and adjustment of flanges of various specifications; After adjustment, clamping and fixing operations are performed: two bonding blocks 1 are respectively bonded to both sides of the H-beam flange plate, ensuring that the thick steel plate 5 welded to the bonding surface of the bonding block 1 is tightly bonded to the top and bottom surfaces of the flange plate. By inserting and tightening the fixing bolts 8 at the lower ends of the opposite surfaces of the two bonding blocks 1, the two bonding blocks 1 clamp the flange plate from both sides. Then, the abutment bolts 3 in the bolt holes on the top surface of the extension plate 2 are screwed, so that one end of the bolt 3 passes through the through hole on the top surface of the thick steel plate 5 and abuts against the top surface of the flange plate, further enhancing the tightness and stability of the clamping and forming a reliable lifting force point. Finally, the lifting connector is inserted into the lifting hole to meet the lifting requirements during the handling, transfer and installation of the H-beam, making it easy to accurately lift the H-beam to the designated working position. After clamping and fixing, activate the detection assembly: By screwing in the screw-in bolts 12 at the opposite ends of the two mounting blocks 10, drive the movable block in the mounting groove to slide along the mounting groove, adjusting the relative position of the sleeve and telescopic sleeve on the opposite surface of the movable block; adjust the telescopic sleeve's extension and retraction amount according to the flange thickness, tighten the locking bolts 11 between the telescopic sleeve's telescopic end and the fixed sleeve to fix their positions, so that one end of the battery box fixed to the opposite surface of the fixed sleeve and the sleeve extends into the sleeve. At this time, the spring 13, which is abutted by the force-bearing end of the pressure sensor installed on the battery box, forms a pre-tightening contact with the inner bottom surface of the sleeve. The spring 13 provides a stable pre-tightening force for the pressure sensor. Under normal clamping conditions, the pressure sensor... The force sensor monitors the stable pressure value in real time. During the hoisting process, the triangular plate welded at the corner of the outer wall of the bonding block 1 can enhance the structural rigidity of the bonding block 1 and prevent deformation during clamping. If the fixing bolt 8 becomes loose, causing the clamping force of the clamp to change, the pressure on the pressure sensor will fluctuate. At this time, the pressure sensor will immediately send a signal to trigger the alarm light column on the outer wall of the battery box to flash, and promptly report the clamping abnormality. After the hoisting operation is completed, the abutment bolt 3 and fixing bolt 8 are loosened in sequence, the fixing plate 4 is pulled out and the extension plate 2 is slid back, the locking bolt 11 is loosened and the telescopic sleeve is adjusted to reset, and finally the clamp is removed to complete the entire usage process.
