Description

Technical Field

[0001] The invention relates to the technical field of H-beam processing and production, in particular to a safety clamp for H-beam transfer. Background Art

[0002] H-shaped steel is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost savings and light structure weight, and is widely used in various fields.

[0003] In the production process of H-beam, due to its large size and heavy weight, it is impossible to move it manually. Therefore, whether it is further processing or loading and unloading operations, lifting equipment is required for lifting operations. However, when the H-beam is processed in the next step, it is often only necessary to move the H-beam a short distance. At this time, if the lifting method of lifting equipment is still used, it is not only time-consuming and labor-intensive to operate, but also due to the small interval between the processing equipment in adjacent steps, the range of movement of the H-beam during the lifting process is small, and it is very easy to collide and cause safety accidents. In order to meet the short-distance transfer operation of H-beam, although some transfer equipment for H-beam transfer is disclosed in the prior art, the use of these transfer equipment still requires the lifting equipment to lift the H-beam to the transfer equipment before the transfer operation can be carried out, which is extremely inconvenient.

[0018] The technical solution of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. indicating directions or positional relationships, they only correspond to the drawings of the present invention and are for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific direction.

[0019] Please refer to the instruction manual Figure 1-7 , the present invention provides a technical solution: Embodiment 1, a safety clamp for H-beam transfer, including two support clamps 2 arranged in mirror image, the support clamp 2 including a base 7 and a clamp 4, a plurality of evenly distributed universal wheels 8 are arranged at the bottom of the base 7, the universal wheels 8 are installed in an embedded manner, and the stability of the base 7 can be effectively improved, and the upper part of the base 7 is respectively provided with a clamp 4 for clamping and supporting the end of the H-beam 1, and a hydraulic cylinder 5 for driving the clamp 4 to be raised and lowered. Specifically, the clamp 4 includes a vertical plate 12, a top plate 9 and a support member 15, and the vertical plate 12 is provided with a plurality of uniformly distributed universal wheels 8. The universal wheels 8 are installed in an embedded manner, and the stability of the base 7 can be effectively improved, and the upper part of the base 7 is provided with a clamp 4 for clamping and supporting the end of the H-beam 1, and a hydraulic cylinder 5 for driving the clamp 4 to be raised and lowered. Specifically, the clamp 4 includes a vertical plate 12, a top plate 9 and a support member 15, and the vertical plate 12 is provided with a plurality of uniformly distributed universal wheels 8. The universal wheels 8 are installed in an embedded manner, and the stability of the base 7 can be effectively improved ... The plate 12 is vertically arranged on one side of the upper surface of the base 7. A support member 15 is provided on the lower side of the plate surface of the vertical plate 12 facing the H-shaped steel 1, which is perpendicular to the vertical plate 12 and protrudes out of the base 7. A top plate 9 is provided on the upper side of the plate surface of the vertical plate 12 facing away from the H-shaped steel 1. The hydraulic cylinder 5 is placed between the top plate 9 and the base 7, and the output end of the hydraulic cylinder 5 is connected to the top plate 9. The hydraulic cylinder 5 can be a jack or other electric control or pneumatic cylinder. The H-shaped steel 1 realizes its rotation and movement by supporting the two ends of the H-shaped steel 1 with two support fixtures 2. When the H-beam 1 is transported and moved over a short distance, the staff can push the two supporting clamps 2 to the two ends of the H-beam 1 respectively, and then push the supporting member 15 to the lower part of the web at the end of the H-beam 1 or the lower part of the upper wing plate, and then use the hydraulic cylinder 5 to jack up the clamp 4, thereby realizing the jacking support of the H-beam 1. When the H-beam 1 is separated from the ground, the staff can use the universal wheels 8 at the bottom of the base 7 to easily push the H-beam 1 to move, avoiding the traditional method of bundling and lifting with lifting equipment, greatly improving the rotation efficiency of the H-beam 1, and reducing the occurrence of safety accidents.

[0020] In the second embodiment, during the process of the hydraulic cylinder 5 lifting the clamp 4, in order to ensure that the clamp 4 can maintain a vertical and stable lifting and lowering, a limit rod 6 perpendicular to the base 7 is provided on one side of the upper surface of the base 7, and a limit groove 13 corresponding to and adapted to the limit rod 6 is provided on the lower end surface of the vertical plate 12. A plurality of limit rods 6 and limit grooves 13 can be provided. Through the plug-in limit of the limit rod 6 and the limit groove 13, the clamp 4 can always maintain a vertical and stable lifting and lowering, which greatly improves the stability of the support for the H-shaped steel 1.

[0021] Embodiment 3: When the H-beam 1 is loaded and unloaded or transported at a high place, the method of lifting and supporting the H-beam 1 to push and move it cannot meet the demand, and the H-beam 1 still needs to be hoisted. In order to facilitate the hoisting of the H-beam 1, a lifting ring 3 is provided on the upper surface of the top plate 9, and a slot 10 corresponding to the output end of the hydraulic cylinder 5 is provided on the lower surface of the top plate 9. The output end of the hydraulic cylinder 5 is plugged into the slot 10. The lifting equipment can directly lift the clamp 4 and its upper support H-beam 1 by binding with the lifting ring 3; The support of the H-shaped steel 1 by the support member 15 alone cannot ensure the safety and stability during the lifting operation. In order to ensure the safety of lifting, the plate surface of the vertical plate 12 facing the H-shaped steel 1 is also provided with a movable pressing plate 11 which is parallel to and corresponds to the supporting member 15, and a driving mechanism 14 for driving the movable pressing plate 11 to be raised and lowered. Specifically, the driving mechanism 14 includes a slide groove 17 and a driving screw 19. The plate surface of the vertical plate 12 facing the H-shaped steel 1 is provided with a slide groove 17 which is arranged perpendicular to the ground. A driving screw 19 which is arranged along the axial direction of the slide groove 17 is rotatably installed in the slide groove 17. The upper end of the driving screw 19 passes through the slide groove 17, and a rotating handle 16 is provided at its end. A slider 25 which is slidably matched with the slide groove 17 is provided on one side of the movable pressing plate 11. The slider 25 is provided with a screw hole 26 which passes through the slider 25 and is threadedly matched with the driving screw 19. The web or wing plate at both ends of the H-shaped steel 1 can be clamped by the cooperation between the movable pressing plate 11 and the supporting member 15, thereby providing a guarantee for the safety of subsequent lifting operations. In order to ensure the horizontal stability of the movable pressure plate 11 and prevent the movable pressure plate 11 from exerting pressure on the driving screw 19 and affecting the subsequent lifting and lowering adjustment of the movable pressure plate 11, the groove 17 is provided with an inner folding edge 18, and the two sides of the slider 25 are provided with notches 27 adapted to the inner folding edge 18.

[0022] Embodiment 4: During the process of supporting or clamping the H-beam 1 for lifting, if the H-beam 1 is placed in a way that the web is parallel to the ground, the support member 15 can be placed at the lower part of the web to support it, and the movable pressure plate 11 can also directly clamp the upper part of the web. If the H-beam 1 is placed in a way that the web is perpendicular to the ground, the support member 15 can only support the upper wing plate on one side of the web, which makes it impossible to ensure the level of the H-beam 1, thereby affecting the safety and stability of the subsequent transportation and lifting of the H-beam 1. For this reason, the support member 15 includes two support blocks 20, and the vertical plate 12 faces the H-beam. Support blocks 20 are arranged on both sides of the lower part of the plate surface of the steel 1, and a slot 21 for clamping the inner web of the H-shaped steel 1 is formed between the two support blocks 20. When supporting the H-shaped steel 1, if the web of the H-shaped steel 1 is parallel to the ground, the bottom of the web of the H-shaped steel 1 can be supported by the two support blocks 20. If the web of the H-shaped steel 1 is vertical to the ground, the bottom of the wing plate on the upper side of the H-shaped steel 1 can be supported by the two support blocks 20. The web is just clamped into the slot 21 between the two support blocks 20, which effectively ensures the horizontal and stable support of the H-shaped steel 1 and provides guarantee for the subsequent transportation safety.

[0023] Embodiment 5: If the width of the slot 21 is much larger than the thickness of the web, the H-beam 1 is very likely to slide horizontally during the transportation of the H-beam 1, which may cause certain safety hazards. In order to ensure the stability of the support and lifting of the H-beam 1, a screw 23 with a thread running through the support block 20 is provided on the end face of any support block 20 away from the other support block 20, and a top plate 22 is provided at the end of the screw 23 located in the slot 21, and a handle 24 is provided at the other end of the screw 23, which can drive the top plate 22 to contact and limit the web in the slot, thereby ensuring the safety and stability of the H-beam 1 during subsequent support, transportation and lifting.

[0024] Embodiment 6: In the process of horizontally supporting the H-shaped steel 1, since the base 7 is located on the outside of the H-shaped steel 1, the force on the base 7 is not uniform. When the H-shaped steel 1 is pushed to move, the support fixture 2 is easy to tilt toward the H-shaped steel 1, affecting the transportation operation of the H-shaped steel 1. In order to ensure the horizontal stability of the base 7, the side of the end face of the base 7 facing the H-shaped steel 1 is hingedly connected to the sub-base 31 through a hinge 28. The end face of the base 7 facing the sub-base 31 is provided with a socket 29, and the end face of the sub-base 31 facing the base 7 is provided with a plug rod 30 adapted to the socket 29. The lower part of the sub-base 31 is also provided with a plurality of uniformly distributed universal wheels 8; When the support fixture 2 lifts up the end of the H-beam 1, the H-beam 1 should be lifted up until its lower surface is not lower than the upper surface of the base 7, and then the hinge 28 is used to rotate the sub-base 31 to the lower part of the H-beam 1, and the insertion rod 30 on the end face of the sub-base 31 is plugged into the insertion hole 29 on the end face of the base 7. At this time, the cooperation between the base 7 and the sub-base 31 can greatly improve the stability of the support fixture 2. If the H-beam 1 with its web perpendicular to the ground is supported and transported, the H-beam 1 can be lowered to the sub-base 31 so that the wing plate at the lower part of the H-beam 1 is placed on the upper part of the sub-base 31. This can not only further improve the stability of the push and move of the H-beam 1, but also reduce the pressure on the support member 15 and the hydraulic cylinder 5.
