Description

Technical Field

[0001] The invention relates to the technical field of water conservancy and hydropower, and in particular to a fastening device for water conservancy and hydropower construction. Background Art

[0002] Water conservancy and hydropower engineering mainly involves the survey, planning, design, construction, scientific research and management of water conservancy and hydropower engineering. With the serious shortage of water resources in my country and even the world and the increasingly severe energy crisis, it is imperative to accelerate the management of rivers, give priority to the development of hydropower, develop and utilize hydropower and optimize the allocation of water resources. Water conservancy and hydropower projects often lay or bury many pipelines for the allocation of water resources. In order to improve the stability of pipelines and the sealing between different pipelines, and reduce the damage and separation of pipelines, pipeline fastening devices are usually installed at the connections of different pipelines.

[0003] According to the utility model patent of a water conservancy and hydropower construction fastening device with patent number CN220688233U, the utility model includes a first fastening plate and a protective mechanism. Through the setting of the protective mechanism, in the process of protecting the water conservancy and hydropower construction pipeline, the card block is first inserted into the inner wall of the card slot to limit the first protective pad, and then the first screw is screwed clockwise into the first threaded hole and the second threaded hole to fix the first protective pad. At this time, the water conservancy and hydropower construction pipeline is placed above the first protective pad, and then the motor is started. The motor drives the ball screw to rotate through the rotating shaft. At the same time, the rotating ball screw drives the ball nut, the second fastening plate and the second protective pad to fall downward until the second protective pad fastens the water conservancy and hydropower construction pipeline, so that the first protective pad and the second protective pad completely wrap the water conservancy and hydropower construction pipeline, thereby effectively protecting the pipeline.

[0004] Although the above technical solution can achieve the function of fixing the pipelines in water conservancy and hydropower construction, the technical solution cannot be flexibly adjusted according to the diameters of different pipelines. In actual water conservancy and hydropower construction, it is often necessary to fix two pipelines in connection. The shock absorbing mechanism of the technical solution will affect the stability of the two pipelines when they are connected to a certain extent, thereby affecting their normal fixed connection work, and its applicability is low. Summary of the invention

[0005] The purpose of the present invention is to provide a fastening device for water conservancy and hydropower construction, which can be flexibly adjusted and fixed according to the diameters of different pipelines during construction, and will not affect the stability of the two pipelines when they are connected after fixation, thereby not affecting its normal pipeline fixing and connection work.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A fastening device for water conservancy and hydropower construction, comprising a base, supporting feet arranged on the left and right sides of the bottom of the base, the left and right sides of the upper end of the outer wall of the base are downwardly provided with slide grooves at the position of the axis thereof, the inner wall of each slide groove near the middle of the base is rotatably connected with a first threaded rod extending from the outer wall and rotatably connected thereto, each slide groove is provided with a slide seat threadedly connected to the corresponding first threaded rod and sliding along the length direction thereof and extending from its open end, the upper end of each slide seat is horizontally provided with a support plate, the middle position of the upper end of each support plate is provided with an arc-shaped support seat, the front and rear ends of the upper end of each support plate are relatively provided with telescopic rods at the position of the same axis of the corresponding support seat, and a U-shaped connecting rod is matched between the upper ends of the two relatively arranged telescopic rods;

[0008] A threaded hole is provided inwardly at the lower end of the left and right sides of the outer wall of each connecting rod, and each threaded hole is threadedly connected to a fixing component passing through its two ends, and the inner wall of each fixing component and the upper end of each support seat are provided with a matching anti-slip pad, and columns are relatively arranged at the front and rear ends on the left and right sides of the upper end of the base, and a conveying roller with a low middle and high sides is rotatably connected between the inner walls of each of the two relatively arranged columns, and each conveying roller and the support seat are located at the same axial position height, and the front and rear ends of the upper end of each support plate are rotatably provided with a positioning component for fixing the telescopic rod near the corresponding telescopic rod, and the upper end of each connecting rod is provided with a limiting block on both sides of the corresponding positioning component.

[0009] By adopting the above technical solution, when using, first move the device to the construction site and fix the base through the supporting feet, then pull the telescopic rod to the longest state and fix it through the connecting rod, then place the pipe to be connected and fixed on the conveying roller, then push the pipe, let its front end pass through the two telescopic rods and let it contact with the upper end of the corresponding support seat, then adjust the length of the telescopic rod, let the fixing component be located at an appropriate position on the outer wall of the pipe, then rotate the fixing component in the threaded hole and let its inner wall contact with the outer wall of the pipe, fix the pipe on the base through two relatively arranged fixing components, then adjust the height of the positioning component and fix the telescopic rod at a corresponding height through the connecting rod, so as to improve the fixing effect of the fixing component on the pipe and prevent the front end of the pipe from tilting upward;

[0010] After one pipe is fixed, the other pipe is fixed on the base in the same way. When fixing the pipe, the anti-slip pad can not only improve the fixing effect of the pipe, but also reduce the rigid force of the fixing component and the support seat on the pipe during fixing. When both pipes are fixed, rotate the first threaded rod in the slide groove, and drive the support plate to slide on the base through the slide to make the two pipes close and contact, and then the two pipes can be connected and fixed. When the pipe is moved by the support plate, the conveying roller can not only provide certain support for the pipe, but also improve the smoothness of moving the pipe.

[0011] The present invention is further configured as follows: a gap is left between each support plate and the upper end of the base and between the lower end of each slide and the bottom of the corresponding slide groove, and a plurality of rollers distributed in an array and in contact with the upper end of the base are arranged on the left and right sides of the lower end of each support plate.

[0012] By adopting the above technical solution, not only the smoothness of moving the slide seat can be improved, but also the force applied to the first threaded rod can be reduced.

[0013] The present invention is further configured as follows: the fixing assembly includes an arc-shaped fixing plate, a U-shaped second threaded rod disposed on the outer wall of the fixing plate and rotatably connected thereto, and each second threaded rod is threadedly connected to a corresponding threaded hole.

[0014] The present invention is further configured as follows: a worm gear is installed at one end of each first threaded rod extending out of the corresponding slide groove, and the left and right sides of the base are rotatably connected with worms that mesh with the corresponding worm gear and are used to control the rotation of the first threaded rod, and an auxiliary rod arranged in a cross shape is arranged at one end of each worm.

[0015] By adopting the above technical solution, it is not necessary for workers to operate under the pipes when connecting two pipes, which improves the convenience of operation and reduces safety hazards to a certain extent.

[0016] The present invention is further configured such that: each two relatively arranged positioning components are staggered.

[0017] By adopting the above technical solution, the stability of the connecting rod when being fixed can be improved.

[0018] The present invention is further configured as follows: the positioning assembly includes a positioning seat, a third threaded rod rotatably connected to the upper end of the outer wall of the positioning seat, a threaded sleeve threadedly connected to the outer wall of the third threaded rod, and a positioning rod arranged on one side of the outer wall of the threaded sleeve and arranged in an L shape.

[0019] In summary, the present invention has the following beneficial effects:

[0020] First, the present invention can be flexibly adjusted and fixed according to the diameters of different pipes during construction, and the stability of the two pipes when they are connected after fixation will not be affected, thereby not affecting the normal pipe fixing and connection work;

[0021] Secondly, the conveying roller of the present invention can not only support the pipeline when fixing the pipeline to prevent the front end of the pipeline from tilting, but also improve the smoothness of the pipeline when moving the pipeline;

[0022] Thirdly, after fixing the pipeline, the present invention can also drive the pipeline to move, which is convenient for connecting two pipelines and can also reduce the labor intensity of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0029] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by terms such as “upper”, “lower”, “left”, “right”, “front”, “back”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0030] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Example, see Figure 1-4 A fastening device for water conservancy and hydropower construction includes a base 1, legs 11 arranged on the left and right sides of the bottom of the base 1, a slide groove 12 is opened downward at the axial position on the left and right sides of the upper end of the outer wall of the base 1, and a first threaded rod 13 extending from the outer wall and rotatably connected to the inner wall of each slide groove 12 near the middle of the base 1 is rotatably connected, and a worm gear 31 is installed at one end of each first threaded rod 13 extending from the corresponding slide groove 12, and a worm gear 31 meshing with the corresponding worm gear 31 and used to control the rotation of the first threaded rod 13 is rotatably connected on the left and right sides of the base 1. A worm 32, one end of each worm 32 is provided with an auxiliary rod 33 arranged in a cross shape, each slide groove 12 is provided with a slide seat 14 which is threadedly connected to the corresponding first threaded rod 13 and slides along its length direction and extends out of its open end, and a support plate 15 is horizontally arranged at the upper end of each slide seat 14, and there is a gap between each support plate 15 and the upper end of the base 1 and between the lower end of each slide seat 14 and the bottom of the corresponding slide groove 12, and a plurality of rollers 16 distributed in an array and in contact with the upper end of the base 1 are arranged on the left and right sides of the lower end of each support plate 15.

[0033] A support seat 17 with an arc shape is provided in the middle position of the upper end of each support plate 15, and a telescopic rod 18 is relatively provided at the front and rear ends of the upper end of each support plate 15 at the position of the same axis of the corresponding support seat 17, and a U-shaped connecting rod 19 is matched between the upper ends of each two relatively arranged telescopic rods 18, and a threaded hole 2 is opened inward at the lower end of the left and right sides of the outer wall of each connecting rod 19, and each threaded hole 2 is threadedly connected with a fixing component 21 passing through its two ends, and the fixing component 21 includes an arc-shaped fixing plate 22, a second threaded rod 23 arranged on the outer wall of the fixing plate 22 and rotatably connected thereto, and each second threaded rod 23 is threadedly connected to the corresponding threaded hole 2, and the inner wall of each fixing plate 22 and the upper end of each support seat 17 are provided with a non-slip pad 24 matching therewith.

[0034] A column 34 is relatively set at the front and rear ends of the left and right sides of the upper end of the base 1, and a conveying roller 35 with a lower middle and higher sides is rotatably connected between the inner walls of each relatively set two columns 34. Each conveying roller 35 and the support seat 17 are located at the same axial position height, and a positioning component 25 for fixing the telescopic rod 18 is rotatably provided at the front and rear ends of the upper end of each support plate 15 near the corresponding telescopic rod 18. The positioning component 25 includes a positioning seat 26, a third threaded rod 27 rotatably connected to the upper end of the outer wall of the positioning seat 26, a threaded sleeve 28 threadedly connected to the outer wall of the third threaded rod 27, and a positioning rod 29 arranged on one side of the outer wall of the threaded sleeve 28 and arranged in an L shape. Each relatively set two positioning components 25 are staggered, and the upper end of each connecting rod 19 is provided with a limit block 3 on both sides of the corresponding positioning component 25.

[0035] Method of use: When in use, first move the device to the construction site and fix the base 1 through the support feet 11, then pull the telescopic rod 18 to the longest state through the connecting rod 19 and support it through the positioning rod 29 on the positioning assembly 25, then place the pipe to be connected and fixed on the conveying roller 35 on the column 34, and then push the pipe so that its front end passes through the two telescopic rods 18 and contacts the upper end of the corresponding support seat 17, then adjust the length of the telescopic rod 18 so that the fixing assembly 21 is located at an appropriate position on the outer wall of the pipe, and then rotate the second threaded rod 23 in the threaded hole 2 to allow the fixing plate 22 to contact the outer wall of the pipe. When rotating the second threaded rod 23, the pipe is clamped and fixed on the base 1 through two relatively arranged fixing assemblies 21, and then adjust the height of the positioning assembly 25, first let the threaded sleeve 28 rotate on the third threaded rod 27 and let the positioning rod 29 approach the connecting rod 19.

[0036] When the positioning rod 29 contacts the connecting rod 19, the third threaded rod 27 on the positioning seat 26 is rotated to drive the threaded sleeve 28 to continue to move downward, and the positioning rod 29 will not rotate by following the third threaded rod 27 under the limiting effect of the limit block 3, so as to fix the telescopic rod 18 at a corresponding height, thereby improving the fixing effect of the fixing component 21 on the pipeline and preventing the front end of the pipeline from tilting upward. The two positioning components 25 arranged relatively and staggered can improve the stability of the pipeline fixation. After one pipeline is fixed, the other pipeline is fixed on the base 1 in the same way. When fixing the pipeline, the anti-slip pad 24 can not only improve the fixing effect of the pipeline, but also reduce the rigid force of the fixing component 21 and the support seat 17 on the pipeline during fixing.

[0037] When both pipes are fixed, the worm 32 is rotated and the first threaded rod 13 in the slide groove 12 is driven to rotate through the worm wheel 31 meshing therewith, and the first threaded rod 13 drives the support plate 15 to slide on the base 1 through the slide seat 14 to make the two pipes close to and contact, and the roller 16 on the support plate 15 can not only improve the smoothness of the support plate 15 when sliding, but also reduce the force applied by the staff to the worm 32 to a certain extent, thereby reducing the labor intensity of the staff. At the same time, the setting of the worm wheel 31 and the worm 32 can prevent the staff from operating under the pipe to reduce safety hazards. Then the two pipes can be connected and fixed, and when the pipe is moved by the support plate 15, the conveying roller 35 can not only play a certain supporting role for the pipe, but also improve the smoothness when moving the pipe.

[0038] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it will be protected by the patent law.
