Description

Technical Field

[0001] The present application relates to the technical field of fastening structures, and more specifically, to a fastening structure used in water conservancy and hydropower construction. Background Art

[0002] In water conservancy and hydropower construction, it involves fastening and positioning of pipelines. In order to solve the problem of cumbersome fastening of pipelines in the prior art, a Chinese patent with application number CN202222812600.0 provides a patent for a fastening device for water conservancy and hydropower construction. On the one hand, although the distance between the two fixing rings can be adjusted to facilitate positioning of the pipeline between the two fixing rings, the distance between the two limiting rods is fixed, so that the pipeline with a larger diameter cannot be passed between the two limiting rods, and thus cannot be fixed by the two fixing rings, resulting in It is not practical; on the other hand, due to the provision of a spring, it is rather laborious to pull the card cap upward to drive the moving column, and after pulling it upward, it is necessary to keep the upward state, so that the first chain tooth bar is separated from the second chain tooth bar, and the two fixed rings are adjusted left and right to facilitate passing the pipe through the two fixed rings. After the pipe passes through the two fixed rings, the operator is required to push the two fixed rings toward the middle and apply pressure to make the inner walls of each fixed ring fit with the outer wall of the pipe until the adjustment of the two fixed rings is completed, which increases the labor intensity of the operator and is very troublesome.

[0003] The document with prior art announcement number CN 220727336 U provides a fastening structure for water conservancy and hydropower construction. The device adjusts the distance between the two clamping support parts and can also adjust the height of the top plate, so that pipes of different specifications can be locked, which effectively improves the practicality; on the other hand, when inserting and clamping the pipe, there is no need to apply force to the pressure plate all the time, and the locking is simpler and the operation is more labor-saving. It also has the beneficial effects of simple structure, low manufacturing cost and not easy to damage.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: although the device can fix pipes with different outer diameters, when fixing pipes with different outer diameters, the curvature of different pipes and the contact area with the pressure plate and the curved surface are also different, and the non-contact surface lacks avoidable limit, which will cause the pipe to shake between the pressure plate and the base.

[0005] In view of this, we propose a fastening structure for water conservancy and hydropower construction. Utility Model Content

[0006] 1. Technical issues to be solved

[0007] The purpose of this application is to provide a fastening structure for water conservancy and hydropower construction, which solves the technical problems in the above-mentioned background technology and realizes the technical effects of improving the clamping effect of pipes with different outer diameters and avoiding the shaking of pipes.

[0008] 2. Technical solution

[0009] The technical solution of this application provides a fastening structure for water conservancy and hydropower construction, including: an upper clamping plate, a lower clamping plate and multiple sets of bolt and nut groups. A fixing plate is integrally formed at the bottom of the lower clamping plate. The upper clamping plate and the lower clamping plate are symmetrically provided with installation openings. Multiple side clamping plates are stacked in the installation openings. The bolt and nut groups pass through the upper clamping plate and the lower clamping plate, and the bolt and nut groups pass through the side clamping plates. The side clamping plates slide along the radial direction of the pipe.

[0010] By adopting the above technical solution, the fastening structure can be fixed through the fixing plate. Then, the pipe is clamped in the arc-shaped groove between the upper clamping plate and the lower clamping plate. The upper and lower surfaces of the pipe are in contact with the arc-shaped surfaces of the upper clamping plate and the lower clamping plate. Then, multiple side clamping plates are slid towards the pipe and in contact with it. Finally, through the tightening of multiple bolt and nut groups, the upper clamping plate, the lower clamping plate and multiple side clamping plates can be fixed. Furthermore, the side clamping plates limit the gap between the pipe and the clamping plates, preventing the pipe from shaking between the upper clamping plate and the lower clamping plate.

[0011] As an optional solution of the technical solution of this application document, large through holes are provided on the separated sides of the upper clamping plate and the lower clamping plate. Small through holes coaxial with the large through holes are provided on the opposite sides of the upper clamping plate and the lower clamping plate.

The outer diameter of the screw part is adapted to the inner diameter of the small through hole. The outer diameter of the nut is smaller than the inner diameter of the large through hole.

[0013] By adopting the above technical scheme, the screw part passes upward from the large through hole at the bottom, and then the threaded part of the screw part passes through the large through hole of the upper clamping plate. At this time, the head is placed in the large through hole below, and the nut is placed in the large through hole above. The outer diameter of the screw part is adapted to the inner diameter of the small through hole to prevent the screw part from shaking. Then the nut is rotated clockwise to make the nut move toward the head. At this time, the multiple side clamps on the left side are squeezed against each other and the inner wall of the installation port. Under the action of extrusion and / or friction, the multiple side clamps are fixed, and under the action of the screw part and the nut, the upper clamping plate and the lower clamping plate can be fixed, so that the pipe is clamped between the upper clamping plate and the lower clamping plate, and the gap between the pipe and the clamping plate is limited by four groups of multiple side clamps on both sides of the pipe.

[0014] As an optional solution of the technical solution of the present application document, rubber pads are fixedly installed on opposite sides of the side clamps, and the outer surface of the side clamps is wrapped with a rubber layer.

[0015] By adopting the above technical solution, the friction coefficient with the pipeline can be increased by abutting the rubber pad against the pipeline, and at the same time it also plays a role in buffering the pipeline, and a rubber layer is clamped on the outer surface of the side clamp to increase the friction coefficient between adjacent side clamps.

[0016] As an optional solution of the technical solution of the present application document, the nut is coaxially fixed with a sleeve adapted to the inner diameter of the large through hole.

[0017] By adopting the above technical solution, the sleeve is inserted into the large through hole. When the nut is threadedly connected with the screw part, the side clamp is squeezed by the sleeve, and the sleeve is placed in the large through hole above to facilitate positioning of the nut.

[0031] A fastening structure for water conservancy and hydropower construction includes: an upper clamping plate 1, a lower clamping plate 2 and multiple bolt-nut groups 5. A fixing plate 3 is integrally formed at the bottom of the lower clamping plate 2. Installation openings 11 are symmetrically formed in both the upper clamping plate 1 and the lower clamping plate 2. Multiple side clamping plates 4 are stacked in the installation openings 11. The bolt-nut group 5 passes through the upper clamping plate 1 and the lower clamping plate 2, and the bolt-nut group 5 passes through the side clamping plates 4, and the side clamping plates 4 slide along the radial direction of the pipeline.

[0032] Refer to Figures 1 - 7, fix the fastening structure by fixing the fixing plate 3, then clamp the pipeline in the arc-shaped groove between the upper clamping plate 1 and the lower clamping plate 2. The upper and lower surfaces of the pipeline are abutted against the arc-shaped surfaces of the upper clamping plate 1 and the lower clamping plate 2. Then slide multiple side clamping plates 4 towards the pipeline and make them abutted. Finally, lock them with multiple bolt-nut groups 5, and the upper clamping plate 1, the lower clamping plate 2 and multiple side clamping plates 4 can be fixed. Furthermore, the side clamping plates 4 limit the gap between the pipeline and the clamping plate to prevent the pipeline from shaking between the upper clamping plate 1 and the lower clamping plate 2.

[0033] Large through holes 12 are provided on the separated sides of the upper clamping plate 1 and the lower clamping plate 2. Small through holes 13 coaxial with the large through holes 12 are provided on the opposite sides of the upper clamping plate 1 and the lower clamping plate 2. The large through holes 12 and the small through holes 13 penetrate the mounting opening 11. Multiple fixing holes 31 are provided on the fixing plate 3.

[0034] The side clamping plate 4 is provided with a strip-shaped hole 41. The bolt-nut group 5 includes a screw rod part 51, a head 52 integrally formed with the screw rod part 51, and a nut 53 threadedly connected to the screw rod part 51. The outer diameter of the head 52 is smaller than the inner diameter of the large through hole 12 and larger than the width of the strip-shaped hole 41. The outer diameter of the screw rod part 51 is adapted to the inner diameter of the small through hole 13, and the outer diameter of the nut 53 is smaller than the inner diameter of the large through hole 12.

[0035] Refer to Figures 2 - 5 , the screw rod part 51 passes upward through the large through hole 12 at the bottom, and then the threaded part of the screw rod part 51 passes out of the large through hole 12 of the upper clamping plate 1. At this time, the head 52 is placed in the lower large through hole 12, the nut 53 is placed in the upper large through hole 12, and the outer diameter of the screw rod part 51 is adapted to the inner diameter of the small through hole 13 to avoid the screw rod part 51 from shaking. Then rotate the nut 53 clockwise so that the nut 53 moves towards the head 52. At this time, multiple side clamping plates 4 on the left side are pressed against each other and against the inner wall of the mounting opening 11. Under the action of the pressing force and / or friction force, multiple side clamping plates 4 are fixed. And under the action of the screw rod part 51 and the nut 53, the upper clamping plate 1 and the lower clamping plate 2 can be fixed, so as to clamp the pipeline between the upper clamping plate 1 and the lower clamping plate 2, and limit the gap between the pipeline and the clamping plate through four groups of multiple side clamping plates 4 on both sides of the pipeline.

[0036] Rubber pads 42 are fixedly installed on the opposite sides of the side clamping plate 4, and a rubber layer wraps the outer surface of the side clamping plate 4.

[0037] Refer to Figure 5 , by abutting the rubber pad 42 against the pipeline, the friction coefficient with the pipeline can be increased, and at the same time, it also plays a role in buffering the pipeline. And a rubber layer is clamped on the outer surface of the side clamping plate 4 to increase the friction coefficient between adjacent side clamping plates 4.

[0038] A sleeve 54 adapted to the inner diameter of the large through hole 12 is coaxially fixed to the nut 53.

[0039] Reference Figure 2 and Figure 4 When inserted into the large through-hole 12 through the sleeve 54, when the nut 53 is threadedly connected to the screw portion 51, at this time, the side clamping plate 4 is extruded by the sleeve 54, and at the same time, the sleeve 54 is placed in the upper large through-hole 12 to facilitate the positioning of the nut 53.

[0040] Working principle: With the cooperation of the expansion bolt in the fixing hole 31, the fixing plate 3 is fixed on the concrete base. The screw portion 51 passes upward through the large through-hole 12 at the bottom, and then the threaded portion of the screw portion 51 passes out of the large through-hole 12 of the upper clamping plate 1. The upper and lower surfaces of the pipe are abutted against the arc surfaces of the upper clamping plate 1 and the lower clamping plate 2. The multiple side clamping plates 4 in the four groups slide along the installation port 11 towards the pipe and abut against the outer wall of the pipe. Subsequently, the nut 53 is rotated clockwise by a wrench, and the nut 53 is extruded towards the direction of the head 52. The relatively moving head 52 and nut 53 mutually extrude the upper clamping plate 1, the lower clamping plate 2, and the multiple side clamping plates 4, and fixation is completed under the action of extrusion and / or friction.
