Description

Technical Field

[0001] The present invention is used in the technical field of steel pipe grooving, and particularly relates to a steel pipe grooving workbench. Background Art

[0002] At present, in engineering projects such as high-speed and building construction, groove connection is usually adopted for pipeline construction. And there are many on-site pipe manufacturing tasks, large grooving amounts, large diameters of pipes, and different pipe specifications. Traditional on-site steel pipe grooving construction uses a grooving support as a support. For pipes with a large diameter (diameter > 200mm) and heavy mass, if there is a slight jump during the grooving rotation process, it is very easy to cause the shaft of the grooving equipment to break. This not only affects the grooving efficiency, but also requires a large investment in production equipment, wastes costs, and poses construction safety hazards. Summary of the Invention

Both the first spacing adjustment group and the second spacing adjustment group include a first threaded connector passing through the chute on the corresponding side and a locking member installed on the first threaded connector. The first threaded connector and the locking member of the first spacing adjustment group are used to lock both ends of the first roller to the first support base correspondingly, and the first threaded connector and the locking member of the second spacing adjustment group are used to lock both ends of the second roller to the first support base correspondingly.

[0010] Combined with the above implementation manners, in some implementation manners of the present invention, the roller mechanism further includes a first L-shaped plate group and a second L-shaped plate group arranged at intervals along the second direction on the first support base. Both the first L-shaped plate group and the second L-shaped plate group include two L-shaped plates arranged at intervals along the first direction. The L-shaped plate includes a bottom plate and a vertical plate provided on one side of the top of the bottom plate.

[0026] In the present invention, unless otherwise clearly defined, terms such as "arranged", "installed", "connected", etc. should be understood in a broad sense. For example, they can be directly connected, or indirectly connected through an intermediate medium; they can be fixedly connected, or detachably connected, or integrally formed; they can be mechanically connected, or electrically connected or capable of communicating with each other; they can be the communication inside two components or the interaction relationship between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in the present invention in combination with the specific content of the technical solution.

[0027] See Figure 1 and Figure 2 , an embodiment of the present invention provides a steel pipe grooving workbench, which includes a support seat and a roller mechanism. The support seat includes a first support seat 11, a second support seat 12, and an elastic telescopic component. The first support seat 11 is arranged on the top of the second support seat 12 and is connected to the second support seat 12 through the elastic telescopic component.

[0028] The roller mechanism includes a first roller 21 and a second roller 22 extending along a first direction. The first roller 21 and the second roller 22 are rotatably installed on the first support seat 11 and are arranged at intervals along a second direction. A steel pipe (not shown in the figure) is placed between the first roller 21 and the second roller 22, and the steel pipe can rotate quickly under the support of the first roller 21 and the second roller 22.

[0029] During operation, place the support base on the ground. The worker places the steel pipe on the first roller 21 and the second roller 22, and then turns on the grooving device (not shown in the figure). The worker then slowly rotates the steel pipe manually or by other means. The steel pipe can rotate smoothly under the action of the first roller 21 and the second roller 22 until the grooving work is completed. During the process of rotating and grooving the steel pipe, since the elastic telescopic component is arranged between the first support base 11 and the second support base 12, the first support base 11 and the second support base 12 become elastically supported. When the rotation of the steel pipe is uneven or the centrifugal force is too large, causing local shaking, the elastic telescopic component can absorb the jumping energy generated during the grooving process, play a buffering role, avoid the steel pipe from jumping and causing the shaft breakage of the grooving device, improve the grooving efficiency, reduce the damage to the grooving device, reduce the production input cost, and reduce or avoid the safety hazard problem caused by the shaft breakage of the grooving device.

[0030] Further, referring to Figure 2 , the roller mechanism further includes a roller spacing adjustment component, which is used to adjust the spacing between the first roller 21 and the second roller 22 to meet the grooving requirements of steel pipes with different diameters and specifications. It can be understood that the roller spacing adjustment component can be directly driven by a driving cylinder, or the spacing can be adjusted by means of a ball screw pair or manual adjustment and locking.

[0031] In some embodiments, referring to Figures 1 to 3 , two chutes 111 are arranged at intervals along the first direction on the first support base 11, and the chutes 111 extend along the second direction. The roller spacing adjustment component includes a first spacing adjustment group 3 arranged at both ends of the first roller 21 and a second spacing adjustment group 4 arranged at both ends of the second roller 22. Both the first spacing adjustment group 3 and the second spacing adjustment group 4 include a first threaded connector 41 passing through the corresponding chute 111 on the corresponding side and a locking member 42 installed on the first threaded connector 41, that is, the first threaded connectors 41 of both the first spacing adjustment group 3 and the second spacing adjustment group 4 pass through the two chutes 111.

[0032] The first threaded connector 41 and the locking member 42 of the first spacing adjustment group 3 are used to lock the two ends of the first roller 21 to the first support seat 11, and the first threaded connector 41 and the locking member 42 of the second spacing adjustment group 4 are used to lock the two ends of the second roller 22 to the first support seat 11. When it is necessary to adjust the spacing between the first roller 21 and the second roller 22, first loosen the locking member 42, take out the first threaded connector 41, and then move the first roller 21 and the second roller 22 to a suitable position, then use the first threaded connector 41 to re-thread the slide groove 111 and the two ends of the corresponding first roller 21 or second roller 22, and then use the locking member 42 to lock the first roller 21 or the second roller 22 to the first support seat 11, so as to complete the spacing adjustment of the first roller 21 and the second roller 22, and meet the requirements of grooving steel pipes of different diameters and specifications.

[0033] Further, see Figures 1 to 4 The roller mechanism further includes a first L-shaped plate group and a second L-shaped plate group spaced apart along the second direction on the first support seat 11, and the first L-shaped plate group and the second L-shaped plate group each include two L-shaped plates 5 spaced apart along the first direction. The L-shaped plate 5 includes a bottom plate 51 and a vertical plate 52 disposed on one side of the top of the bottom plate 51, and the first roller 21 is rotatably mounted on the vertical plates 52 of the two L-shaped plates 5 of the first L-shaped plate 5 group through the first wheel shaft 211, and the bottom plates 51 of the two L-shaped plates 5 of the first L-shaped plate 5 group are correspondingly locked to the first support seat 11 through the first threaded connector 41 and the locking member 42 of the first spacing adjustment group 3, so as to realize a detachable connection between the first roller 21 and the first support seat 11, and facilitate installation.

[0034] The second roller 22 is rotatably mounted on the vertical plates 52 of the two L-shaped plates 5 of the second L-shaped plate 5 group through the second wheel axle 221, and the bottom plates 51 of the two L-shaped plates 5 of the second L-shaped plate 5 group are correspondingly locked to the first support seat 11 through the first threaded connector 41 and the locking member 42 of the second spacing adjustment group 4, thereby realizing a detachable connection between the second roller 22 and the second support seat 12 for easy installation.

[0035] Furthermore, the L-shaped plate 5 includes angle steel, which is convenient to obtain and has a relatively low cost of use.

[0036] See also Figure 2 and Figure 3 In some embodiments, the first support seat 11 is provided with a limit block 6 at both ends of each slide groove 111. The limit block 6 is used to resist the L-shaped plate 5 to prevent the first roller 21 and the second roller 22 from sliding toward the two ends of the slide groove 111 due to loosening of the locking member 42 due to vibration, so as to ensure the stability of the roller spacing adjustment and ensure the smooth progress of the steel pipe grooving work.

[0037] Further, continue to refer to Figure 2and Figure 3 At both ends of each sliding groove 111 of the first support base 11, a screw rod 61 extending in the second direction is provided. A nut 62 is sleeved outside the screw rod 61. The screw rod 61 is installed on the first support base 11 through the nut 62. A limit stop 6 is provided at one end of the screw rod 61 close to the sliding groove 111. When the screw rod 61 is rotated clockwise or counterclockwise, the screw rod 61 can drive the limit stop 6 to move under the action of the nut 62 to adapt to different installation distances between the first roller 21 and the second roller 22, ensuring accurate positioning, so as to ensure the stable progress of the grooving process for steel pipes of different diameters and specifications.

[0038] See Figure 1 In some embodiments, the tops of both the first roller 21 and the second roller 22 are higher than the first support base 11, ensuring that when steel pipes of different lengths are placed between the first roller 21 and the second roller 22, the part of the steel pipe extending beyond the first roller 21 and the second roller 22 along the first direction will not interfere with the first support base 11, ensuring that steel pipes of different lengths can smoothly complete the grooving work.

[0039] In some embodiments, see Figure 1 and Figure 3 At the four corner positions of the first support base 11, second threaded connectors 7 extending vertically are provided. A first threaded adjustment block 71, a buffer mounting block 73, and a second threaded adjustment block 72 are sequentially sleeved outside the second threaded connectors 7. The first threaded adjustment block 71 and the second threaded adjustment block 72 serve to fix the buffer mounting block 73. The elastic telescopic assembly includes four elastic buffer members 8 correspondingly installed on the buffer mounting block 73. The top of the elastic buffer member 8 is connected to the first support base 11.

[0040] When the steel pipe is placed between the first roller 21 and the second roller 22, if the steel pipe is in a state of tilting on one side, the height position of the buffer mounting block 73 on the second threaded connector 7 can be adjusted so that the elastic buffer member 8 is compressed to different degrees until the first support base 11 is in a horizontal state, so that the steel pipe can be horizontally arranged between the first roller 21 and the second roller 22, ensuring that the steel pipe can rotate smoothly without shaking, which is conducive to the smooth progress of the grooving work.

[0041] See Figure 2 In some embodiments, see

[0042] See Figure 1 andFigure 2 , a cushion block 9 is provided at the bottom of the second support base 12 to adapt to the unevenness of the ground at the construction site and improve the support stability of the ground for the second support base 12.
