Description

Technical Field

[0001] The invention relates to the field of large pipe hoisting, and in particular to an assembled adjustable clamp for a truss transfer layer. Background Art

[0002] With the development of modernization, the demand for modern large-scale building facilities has also increased. During the construction of large buildings such as airports, high-speed railway stations, museums, etc., truss transfer layers are often set up. During the construction of these truss transfer layer structures, many pipes of different diameters are needed, and the weight of these pipes is relatively large. Clamps are needed in the assembly and lifting of these large pipes to prevent accidents caused by the pipes falling off during the lifting process.

[0003] Conventional clamps are all of fixed diameter. Since a variety of different diameters need to be handled, a variety of clamps with different diameters need to be used. On the one hand, this increases the cost, and on the other hand, the stacking of the clamps takes up a lot of space, affecting on-site construction. The current clamps with variable diameters are often limited by their own structure, resulting in poor fit with the pipe fittings. When faced with heavy pipe fittings, the poor fit can easily cause the pipe fittings to slip during transportation, causing accidents. Summary of the invention

[0004] In order to solve the deficiencies in the above-mentioned prior art, the present invention provides a truss transfer layer assembled adjustable clamp, which can be adjusted in size to adapt to pipes of different diameters, while ensuring a high degree of fit with pipes of different diameters, thereby ensuring the safety of the system.

[0005] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0006] A truss transfer layer assembled adjustable clamp, the clamp comprising a fixed inner ring and a fixed outer frame, the fixed inner ring is used to fix the component to be clamped, the fixed inner ring is fixed on the inner wall of the fixed outer frame, the fixed inner ring is a circular ring structure with adjustable size, and the size of the fixed outer frame is adjusted synchronously with the size of the fixed inner ring.

[0007] Furthermore, the fixed inner ring includes four arc-shaped arc plates, and the arc plates are elastic steel plates.

[0008] Furthermore, the fixed outer frame includes a connecting plate and a fixed plate, the fixed plate is an L-shaped plate, and a connecting hole is provided at each end of the fixed plate. The connecting plate is L-shaped as a whole, and a screw is fixed at each end of the connecting plate. The connecting plate is connected to the fixed plate to form a square frame structure after the screw passes through the connecting hole.

[0009] Furthermore, a rod-shaped slider is provided at each end of the arc plate, and the two adjacent arc plates do not interfere with each other. Two slideways are provided on each of the four surfaces of the fixed outer frame, and the slideways correspond to the rod-shaped sliders one by one. The rod-shaped sliders can slide in the slideways, and a limit block is provided on the top of the rod-shaped slider, and the limit block is used to prevent the rod-shaped slider from detaching from the slideway.

[0010] Furthermore, the axes of the two slideways on each surface of the fixed outer frame are respectively located in different straight lines, and the distance between the side edge of the arc plate and the side edge of the adjacent arc plate that is closest to each other is not less than zero.

[0011] Furthermore, the screw rod is a toothed bolt, the connecting hole is a long strip hole, and the connecting hole is provided with a plurality of limit holes arranged corresponding to the toothed bolt; the rod-shaped slider is a toothed bolt, the slideway is a long strip hole, and the slideway is provided with a plurality of limit holes arranged corresponding to the toothed bolt.

[0012] Furthermore, a protrusion is provided in the middle of one of the plate surfaces of the fixing plate, which is away from the fixed inner ring. A fastening bolt and a fastening bolt hole matching the fastening bolt are provided at the protrusion, and the fastening bolt hole is an oblong hole.

[0013] Furthermore, the two slideways on the plate surface provided with the protrusion are respectively located on both sides of the protrusion.

[0014] Furthermore, the fastening bolt fixes the clamped component by squeezing two arc plates that are closest to each other.

[0015] Based on the above technical solution, the present invention has the following advantages compared with the prior art:

[0016] 1. The four-section arc structure of the inner ring makes the inner ring fit more closely with the outer wall of the pipe when the pipe diameter changes, thereby providing greater clamping force for heavier pipes and ensuring the reliability of the system.

[0017] 2. By setting a frame structure on the outer ring, the force can be transmitted inward through the external frame structure, thereby providing greater force for clamping the pipe fittings and ensuring the reliability of the heavy-weight pipe fittings during transportation.

[0018] 3. The tightening bolts squeeze the arc plate without direct contact with the pipe fittings, so there will be no damage to the surface of the pipe fittings.

[0019] 4. Through the setting of connecting holes and slideways, the clamp can be adjusted accordingly with the diameter of the pipe, and through the setting of limit holes, it is avoided that the clamp is deformed when the force is too large, which affects the reliability and safety of the system.

[0029] The present invention is further described in detail below with reference to the accompanying drawings and specific examples, in order to provide a clearer understanding of its structural type and usage, but this shall not be used to limit the protection scope of the patent of the present invention.

[0030] like Figure 1-9 As shown, a truss transfer layer assembled adjustable clamp comprises a fixed inner ring 1 and a fixed outer frame 2, wherein the fixed inner ring 1 is used to fix the component to be clamped, the fixed inner ring 1 is fixed on the inner wall of the fixed outer frame 2, the fixed inner ring 1 is a circular ring structure with adjustable size, and the size of the fixed outer frame 2 is adjusted synchronously with the size of the fixed inner ring 1.

[0031] The fixed inner ring 1 is composed of four arc-shaped arc plates 3, and the material of the arc plates 3 is elastic steel. The fixed outer frame 2 includes a connecting plate 4 and a fixing plate 5. The fixing plate 5 is an L-shaped plate, and a connecting hole 6 is provided at each end of the fixing plate 5. The connecting plate 4 is L-shaped as a whole, and a screw 7 is fixed at each end of the connecting plate 4. The connecting plate 4 is connected to the fixing plate 5 to form a square frame structure after the screw 7 passes through the connecting hole 6. A rod-shaped slider 8 is provided at each end of the arc plate 3, and the two adjacent arc plates 3 do not interfere with each other. There are There are two slides 9, each of which corresponds to a rod-shaped slider 8 one by one. The rod-shaped slider 8 can slide in the slide 9. A limit block 10 is provided on the top of the rod-shaped slider 8. The limit block 10 is used to prevent the rod-shaped slider 8 from being separated from the slide 9. When the arc plates 3 are arranged in the fixed outer frame 2, in order to avoid interference during deformation, they need to be staggered so as not to affect the movement trajectory of the arc plates 3 during extension and retraction. In order to cooperate with this arrangement, the two slides 9 on each surface are arranged in parallel, so as to achieve a smooth connection between the slide 9 and the corresponding slider without affecting the deformation trajectory of the arc plates 3.

[0032] The connecting hole 6 and the slideway 9 are both arranged as irregular long strip holes, that is, they are arranged in a step-like shape along the length direction of the long strip hole, so as to form a plurality of limit holes, and the screw rod 7 and the rod-shaped slider 8 are both toothed bolt structures, so that when the screw rod 7 slides along the connecting hole 6 and the rod-shaped slider 8 slides along the slideway 9, the position is fixed and does not shift after sliding a certain distance, and there is no passive sliding along the length direction of the long strip hole, and the position can only be changed by active adjustment. A protrusion 11 is provided in the middle of one of the plate surfaces of the fixed plate 5, which is away from the fixed inner ring 1. A fastening bolt 12 and a fastening bolt hole 13 matched with the fastening bolt 12 are provided at the protrusion 11. The fastening bolt hole 13 is a circular hole. The two slideways 9 on the plate surface with the protrusion 11 are respectively located on both sides of the protrusion 11, and the two slideways 9 on the other three plate surfaces are arranged near the middle of the plate surface. The two slideways 9 on each plate surface can be symmetrical about the center of the plate surface to ensure uniform deformation. Since the two slideways 9 on the plate surface with the protrusion 11 are on both sides of the protrusion 11, the shape of the arc plate 3 corresponding to the two slideways 9 should correspond thereto, specifically, the length of one end of the arc plate 3 close to the protrusion 11 should be extended accordingly.

[0033] When the clamp of the present invention is in use, the nut of the fixed screw rod 7 is first loosened to the maximum. At this time, each rod-shaped slider 8 is also located at the maximum displacement, and the openings of the fixed inner ring 1 and the fixed outer frame 2 are both at the maximum. After the fixed inner ring 1 is put on the pipe to be fixed, the two nuts are tightened synchronously so that the openings of the fixed outer frame 2 and the fixed inner ring 1 are evenly reduced until the nuts are tightened until the pipe is completely fixed, and then the clamping force of the pipe is further strengthened by tightening the fastening bolts 12, thereby achieving the maximum clamping of the pipe, and then the next step of transfer operation is carried out.

[0034] Undoubtedly, the present invention has other similar structural compositions and usage modes besides the above-mentioned embodiments. In summary, the present invention also includes other obvious changes and substitutions for those skilled in the art.
