Description

Technical Field

[0001] The utility model relates to the technical field of steel structure processing, in particular to a clamp for processing steel structure beams. Background Art

[0002] Steel beams are horizontal load-bearing components in steel structures. They mainly bear the weight of components such as floor slabs and roofs, and transfer this weight to columns. The components are usually connected by welds, bolts or rivets. Steel beams need to be clamped and fixed during processing. After searching, the Chinese patent announcement number CN220882091U discloses a fixture for processing steel beams. Although the device can clamp and fix steel beams of different lengths by adjusting the distance between a pair of convex slides during use, when the device is loading the steel beams, the steel beams are in friction contact with the surface of the convex slide. The friction resistance of the steel beams is large, and it is difficult for a single operator to complete the loading operation, thereby increasing the labor cost of processing the steel beams. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a fixture for processing steel structure beams, which solves the problems raised in the background art.

[0004] The utility model solves the above-mentioned technical problems as follows:

[0005] A fixture for processing a steel structure beam comprises a first bottom plate, a hook is slidably mounted on the first bottom plate, a base is supported on the first bottom plate, a bracket is welded to the base, a rubber support roller is rotatably mounted on the bracket, and the steel structure beam is clamped and fixed by the hook and the rubber support roller.

[0006] A guide groove is provided on the first bottom plate, a slider is provided at the bottom end of the hook, the hook is slidably installed in the guide groove of the first bottom plate through the slider, and the four corners of the first bottom plate are fixed to the second bottom plate by pins;

[0007] A sliding groove is provided on the second bottom plate, a double-headed screw is rotatably installed in the sliding groove of the second bottom plate, wedge blocks are installed at both ends of the sliding groove of the second bottom plate through the double-headed screw, and the first bottom plate is pushed up and down on the second bottom plate by the wedge blocks.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, a handwheel is welded to one end of the double-ended screw located on the outer side of the second base plate, and a handle is provided on the handwheel. The double-ended screw is driven to rotate by the handle and the handwheel.

[0010] The beneficial effects of adopting the above further scheme are:

[0011] The handle and handwheel design allows the operator to directly drive the double-ended screw with the power of their hands, without the need for an additional power source or complex transmission mechanism. This direct operation method is not only simple and fast, but also improves work efficiency.

[0012] Furthermore, the brackets are evenly distributed on the base, and the brackets and hooks are staggered.

[0013] The beneficial effects of adopting the above further scheme are:

[0014] The even distribution of brackets on the base ensures that the steel beam is evenly and stably supported during processing. This distribution method avoids excessive or uneven force at a single point, thereby reducing the risk of deformation or damage to the steel beam caused by uneven force.

[0015] Furthermore, the base is located on the center line of the first bottom plate, and the hooks are symmetrically distributed on both sides of the base, and the steel structure beam is pressed and fixed on the rubber support roller through the hooks on both sides of the base.

[0016] The beneficial effects of adopting the above further scheme are:

[0017] Using symmetrically distributed hooks to press and secure the steel beams to the rubber support rollers effectively disperses the stress and impact forces applied to the beams during processing. This distribution reduces the risk of deformation caused by excessive force at a single point, protecting the structural integrity and processing quality of the beams.

[0018] Furthermore, a guiding slope is provided on the bottom surface of the first bottom plate, the position and size of the guiding slope are adapted to the wedge block, and the guiding slope assists in guiding the wedge block.

[0019] The beneficial effects of adopting the above further scheme are:

[0020] The design of the guide ramp ensures the wedge moves along a predetermined trajectory, improving guidance accuracy. This precise guidance helps ensure stability and accuracy during the lifting and lowering of the first base plate, reducing errors caused by deviation or tilt. The contact area between the guide ramp and the wedge is relatively large, and the inclined surface design helps distribute contact pressure, thereby reducing friction and wear between the two. This not only extends the life of the clamp but also reduces heat and noise generated by friction, improving the working environment.

[0021] Furthermore, threads in opposite directions are provided at both ends of the double-ended screw, and the two wedge blocks at both ends of the double-ended screw are driven by the double-ended screw to move toward or in opposite directions.

[0022] The beneficial effects of adopting the above further scheme are:

[0023] The design of the double-ended lead screw with opposite thread directions at both ends allows the wedges at both ends to move simultaneously and in opposite directions when the lead screw rotates. By directly utilizing the rotational motion of the double-ended lead screw to drive the wedges to move toward or against each other, the intermediate links in the transmission process, such as gears and belts, are reduced, thereby improving the transmission efficiency. Since the wedges at both ends are driven at the same time, their movement is highly synchronized, which helps to maintain the stability and consistency of the fixture during operation.

[0024] The utility model provides a fixture for processing steel structure beams, which has the following beneficial effects:

[0025] The evenly distributed brackets and carefully designed rubber support rollers on the base provide a firm support for the steel beam, effectively ensuring stability during processing. The staggered placement of hooks and rubber support rollers, coupled with a sliding mounting mechanism, allows the clamp to easily adapt to various steel beam sizes and shapes, significantly enhancing its versatility and flexibility.

[0026] Due to the excellent elasticity of the rubber support roller, the coordinated operation of the hook and rubber support roller can quickly and efficiently clamp and secure the steel beam, greatly simplifying the operation process and effectively improving work efficiency. The interaction between the double-ended screw, handwheel and wedge block realizes the lifting and adjusting function of the first base plate. This not only facilitates the smooth docking and loading of the steel beam onto the device, but also allows the height of the steel beam to be flexibly adjusted according to processing requirements, further increasing the convenience of operation.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1

[0039] A fixture for processing steel structure beams includes a first base plate 5, a hook 1 is slidably mounted on the first base plate 5, a base 13 is supported on the first base plate 5, and a bracket 3 is welded to the base 13. The brackets 3 are evenly distributed on the base 13, and the brackets 3 and the hook 1 are staggered. The uniform distribution of the brackets 3 on the base 13 is like a solid cornerstone, providing uniform and stable support for the steel structure beam 2 during the processing process. This carefully designed distribution method successfully avoids the problem of excessive or uneven force at a single point, significantly reducing the risk of deformation or damage to the steel beam 2 due to uneven force. A rubber support roller 14 is rotatably mounted on the bracket 3. The steel beam 2 is clamped and fixed by the hook 1 and the rubber support roller 14. The base 13 is located on the centerline of the first base plate 5, and the hooks 1 are symmetrically distributed on both sides of the base 13. The hooks 1 on both sides of the base 13 press the steel beam 2 against the rubber support roller 14. The symmetrical distribution of the hooks 1 tightly presses the steel beam 2 against the rubber support roller 14, like a layer of solid armor on the steel beam 2, effectively dispersing the stress and impact force on the steel beam 2 during processing. This distribution method cleverly reduces the risk of deformation of the steel beam 2 due to excessive force at a single point, effectively protecting the structural integrity and processing quality of the steel beam 2.

[0040] Example 2

[0041] like Figures 1 to 4 As shown, the present invention proposes a fixture for processing steel structural beams. Compared with the first embodiment, this embodiment further includes: a guide groove 12 is provided on the first base plate 5, a slider 4 is provided at the bottom end of the hook 1, and the hook 1 is slidably mounted in the guide groove 12 of the first base plate 5 via the slider 4. The four corners of the first base plate 5 are fixed to the second base plate 7 by pins. The bottom surface of the first base plate 5 is provided with a guide bevel 15. The position and size of the guide bevel 15 are adapted to the wedge block 10. The guide bevel 15 assists in guiding the wedge block 10. The ingenious design of the guide bevel 15 is like laying a dedicated track for the wedge block 10, allowing it to move accurately along the predetermined trajectory during movement, thereby significantly improving the guidance accuracy. This precise guidance provides a strong guarantee for the stability and accuracy of the first base plate 5 during the lifting process, effectively reducing errors caused by offset or tilt. The contact area between the guide bevel 15 and the wedge block 10 is relatively large, and the bevel design helps to disperse the contact pressure, thereby significantly reducing friction and wear between the two. This not only effectively extends the service life of the clamp, but also reduces the heat and noise generated by friction, bringing a higher level of comfort to the working environment.

[0042] Example 3

[0043] like Figures 1 to 4As shown, the utility model proposes a fixture for processing steel structure beams. Compared with the first embodiment, this embodiment also includes: a slide groove 11 is opened on the second base plate 7, and a double-headed screw rod 6 is rotatably installed in the slide groove 11 of the second base plate 7. A handwheel 8 is welded to one end of the double-headed screw rod 6 located on the outer side of the second base plate 7. A handle 9 is provided on the handwheel 8. The double-headed screw rod 6 is driven to rotate by the handle 9 and the handwheel 8. The ingenious design of the handle 9 and the handwheel 8 allows the operator to easily drive the double-headed screw rod 6 to rotate directly by the strength of his hands without relying on an additional power source or a complex transmission mechanism. This direct operation mode is not only simple and fast, but also greatly improves work efficiency. The two ends of the chute 11 of the second base plate 7 are meshed with wedges 10 through the double-headed screw 6. The two ends of the double-headed screw 6 are provided with threads in opposite directions. The two wedges 10 at both ends of the double-headed screw 6 are driven by the double-headed screw 6 to move toward or in opposite directions. The unique design of the threads at both ends of the double-headed screw 6 with opposite directions enables the wedges 10 at both ends to move simultaneously and in opposite directions when the screw rotates, just like two dancers with perfect harmony, dancing synchronously on the stage. By directly utilizing the rotational motion of the double-headed screw 6 to drive the wedges 10 to move toward or in opposite directions, the intermediate links in the transmission process, such as gears and belts, are cleverly reduced, thereby significantly improving the transmission efficiency. Since the wedges 10 at both ends are driven simultaneously, their movement is highly synchronized, like a precisely calibrated clock, which helps to maintain the stability and consistency of the fixture during operation. The first base plate 5 is pushed up and down on the second base plate 7 by the wedges 10.

[0044] Working principle:

[0045] The double-ended screw 6 located on the second base plate 7 can drive the wedges 10 at both ends thereof to move toward or in opposite directions inside the slide 11 by rotating the handle 9 and the handwheel 8. Since the thread directions at both ends of the double-ended screw 6 are opposite to each other, when the screw rotates, the wedges 10 at both ends will move synchronously toward the middle or both sides. When the wedges 10 move, they will contact the guide bevel 15 at the bottom end of the first base plate 5, thereby generating thrust. The unique design of the guide bevel 15 enables the thrust of the wedge 10 to be efficiently converted into the lifting and lowering action of the first base plate 5. With the continuous push of the wedge 10, the first base plate 5 can be lifted and lowered on the second base plate 7. This design not only greatly facilitates the smooth docking and loading of the steel structure beam 2 onto the device, but also can flexibly adjust the height of the steel structure beam 2 according to processing requirements, significantly increasing the convenience of operation.

[0046] The hook 1 is installed inside the guide groove 12 of the first base plate 5 in a sliding manner and can be moved to a suitable position along the guide groove 12. When the hook 1 is moved to both sides of the steel structure beam 2, the steel structure beam 2 will first be preliminarily supported by the rubber support roller 14 installed on the bracket 3 on the base 13. Subsequently, the steel structure beam 2 will continue to move forward and be inserted into the hook 1. Through the coordinated support of the hook 1 and the rubber support roller 14, the steel structure beam 2 is clamped and fixed together. This design not only ensures the stability of the clamping, but also effectively reduces the direct friction damage to the surface of the steel structure beam 2 with the help of the rubber support roller 14. In addition, the staggered distribution design of the bracket 3 and the hook 1 makes the steel structure beam 2 more evenly stressed during the clamping process, avoiding deformation or damage caused by excessive force at a single point.

[0047] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.
