Description

Technical Field

[0001] The present invention relates to the technical field of pipeline fixing brackets, and particularly to a pipeline fixing bracket for a municipal comprehensive utility tunnel. Background Art

[0002] A comprehensive utility tunnel is an underground integrated corridor for urban pipelines, that is, a tunnel space is built underground in a city, integrating various engineering pipelines such as electricity, communication, gas, heating, and drainage. It is provided with special inspection openings, hoisting openings, and monitoring systems, and implements unified planning, unified design, unified construction, and management. Among them, the water pipelines in the comprehensive utility tunnel are generally installed through fixing brackets.

[0003] In the prior art, an installation structure for a comprehensive utility tunnel bracket with a publication number of CN116877781A is provided with a first support rod and a second support rod on an installation plate. The first support rod and the second support rod are connected to the inclined part and the horizontal part on the pipeline body through a clamp, that is, connected to the bent part of the pipeline body, and then the position of the second support rod is fixed through a top rod to fix the bent part of the pipeline body and improve the installation quality.

[0004] Although it is convenient to fix the bent part of the pipeline, there are still some problems in the actual use process. Since the positions of the two pipeline support members of the fixing bracket are fixed, it cannot be used when obliquely supporting the pipeline at the turning of the comprehensive utility tunnel, and it cannot be flexibly adjusted according to different usage situations and is suitable for installation in different sites, greatly reducing the application range of the device and unable to meet the installation requirements.

[0005] Therefore, a pipeline fixing bracket for a municipal comprehensive utility tunnel is proposed to solve the technical problem that it cannot be flexibly adjusted according to the on-site installation situation. Summary of the Invention

[0006] The purpose of the present invention is to solve the disadvantages existing in the background art, and a pipeline fixing bracket for a municipal comprehensive utility tunnel is proposed.

[0007] To achieve the above object, the technical solution adopted by the present invention is: A pipeline fixing bracket for a municipal comprehensive utility tunnel, including a base, a fixing plate is fixedly connected to the middle position of the top of the base, a rotating ring is connected to the outside of the fixing plate at the top of the base, a support block is fixedly connected to the side wall of the rotating ring, a top plate is rotatably connected to the top of the fixing plate, a telescopic rod with adjustable length is fixedly connected to the top of the top plate, a first clamp is fixedly connected to the top of the telescopic rod, a rotating disc is rotatably connected to the support block, a second clamp is provided on the rotating disc, an adjusting mechanism for adjusting the inclination angle of the second clamp is provided on the rotating disc, and a rotating mechanism for adjusting the position of the support block is provided inside the rotating ring;

[0008] The rotating mechanism includes a pressing rod. Four straight grooves and four inclined grooves are respectively formed on the inner wall of the rotating ring. The four inclined grooves are arranged between the four straight grooves, and the two ends of each inclined groove are respectively communicated with the upper and lower ends of two adjacent straight grooves. A sunken clamping groove is formed at the top end of the straight groove where it is connected to the inclined groove, so that there is a step between the straight groove and the clamping groove, and the connection between the clamping groove and the inclined groove is inclined;

[0009] A pair of fixing plates are fixedly connected to the top of the base and inside the rotating ring. A pressing block is slidably connected between the fixing plates. The pressing rod is slidably connected through the inner side wall of the pressing block. A pair of upper springs are fixedly connected between the top of the base and the bottom of the pressing block. A limiting disc is fixedly connected to one end of the pressing rod close to the fixed disc. A lower spring is fixedly connected between the side wall of the limiting disc and the side wall of the pressing block. The other end of the pressing rod is slidably connected inside one of the clamping grooves. The pressing block is provided with a limiting mechanism for limiting the position of the rotating ring.

[0010] In the above technical solution, further, four fixing holes for screws to pass through are formed in the top of the base. Two of the fixing holes are arranged on both sides of the support block, and the four fixing holes are symmetrically arranged. By arranging the fixing holes diagonally, it can be avoided that the support block hinders the screws from passing through the fixing holes, affecting the normal installation of the fixing bracket in the utility tunnel.

[0011] In the above technical solution, further, a connecting frame is fixedly connected between the top of the rotating ring and the top of the top plate, and a U-shaped groove is formed in the top of the connecting frame. By arranging the connecting frame, while the rotating ring rotates to adjust the supporting position of the second clamp, the top plate can be driven to rotate, and then the telescopic rod and the first clamp can be driven to rotate, so that the supporting position of the first clamp is always the same as that of the second clamp, improving the convenience performance of the device. And the U-shaped groove can avoid hindering the normal sliding of the U-shaped rod.

[0012] In the above technical solution, further, the limiting mechanism includes a U-shaped rod. Limiting holes adapted to the pressing rod are formed in the side walls of the clamping grooves. Lower right-angle blocks are fixedly connected to the side walls of the limiting disc. A sunken receiving groove is formed in the top of the pressing block beside the lower right-angle blocks. One end of the U-shaped rod is slidably connected through the inside of the receiving groove. The other end of the U-shaped rod is fixedly connected with an upper right-angle block that fits against the inclined surface of the lower right-angle block. A limiting spring is fixedly connected between the bottom of the receiving groove and the bottom of the U-shaped rod. When the pressing rod slides to the clamping groove, the pressing rod will be pushed by the elastic force of the lower spring to insert into the limiting hole, realizing the fixation of the rotating position of the rotating ring and avoiding the rotation of the rotating ring, reducing the stability of the pipeline support process.

[0013] In the above technical solution, further, the adjusting mechanism includes a lead screw. A hinge seat is fixedly connected to the eccentric position at the top of the rotating disk. A support rod is hingedly connected inside the hinge seat. The second clamp is fixedly connected to the top end of the support rod. A bottom plate is fixedly connected to the top of the rotating disk and on the side far from the hinge seat. The lead screw is rotatably connected between the hinge seat and the bottom plate. A rotating block is fixedly connected to the side wall of the lead screw passing through the bottom plate. A sliding block is threadedly connected through the outer wall of the lead screw. A push rod is hingedly connected between the top of the sliding block and the bottom of the support rod. By rotating the rotating block to drive the lead screw to rotate, the threadedly connected sliding block is driven to move, and then the push rod is pushed or pulled to drive the support rod to rotate around the hinge joint with the hinge seat, so as to realize the adjustment of the support inclination angle of the second clamp.

[0014] In the above technical solution, further, a guide rod is fixedly connected between the side walls of the hinge seat and the bottom plate and is arranged through the inner side wall of the sliding block. Through the arrangement of the guide rod, it can play a guiding role during the process of the lead screw driving the sliding block to move, prevent the sliding block from rotating together with the lead screw, and improve the stability of the device during operation.

[0015] In the above technical solution, further, a pair of sector-shaped rack rings are fixedly connected to the top of the base and outside the rotating ring, and the rack rings are arranged diagonally between them. A toothed ring meshing with the rack rings is fixedly connected to the bottom of the rotating disk. A positioning mechanism for restricting the rotating position of the rotating disk is provided on the support block. During the process of driving the rotating ring to rotate by pushing the pressing block, under the meshing action of the toothed ring and the rack rings, the toothed ring will be driven to rotate, and then the rotating disk will be driven to rotate, so as to realize the adjustment of the support direction of the second clamp.

[0016] In the above technical solution, further, the positioning mechanism includes a bolt. A recessed positioning groove is formed at the bottom of the support block beside the toothed ring. A toothed plate meshing with the toothed ring is arranged beside the toothed ring. The bolt is threadedly connected through the top of the support block, and the bottom of the bolt is rotatably connected above the toothed plate. By screwing the bolt in reverse to drive the toothed plate to move downward and slide into the meshing position with the toothed ring, the rotating position of the rotating disk can be restricted.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Through the setting of the rotating mechanism, the position between the first clamp and the second clamp can be flexibly adjusted according to the installation position of the pipeline, and bent pipelines at different positions can be supported, improving the application range of the device.

[0019] 2. Through the mutual cooperation of structures such as the toothed ring, the rack ring and the bolt, when the rotating mechanism adjusts the position of the second clamp, the support inclination direction of the second clamp can be automatically changed, which can cope with the support of pipelines at different positions and further improve the flexibility of the device.

Detailed Description of the Invention

[0028] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0029] Such as Figures 1-7A pipe fixing bracket for a municipal integrated pipe gallery as shown includes a base 1. A fixing plate 2 is fixedly connected to the middle position of the top of the base 1. A rotating ring 3 is connected to the outside of the fixing plate 2 on the top of the base 1. A supporting block 4 is fixedly connected to the side wall of the rotating ring 3. A top plate 5 is rotatably connected to the top of the fixing plate 2. An expansion rod 6 with adjustable length is fixedly connected to the top of the top plate 5. A first clamp 7 is fixedly connected to the top of the expansion rod 6. A rotating disc 28 is rotatably connected to the supporting block 4. A second clamp 8 is provided on the rotating disc 28. An adjusting mechanism for adjusting the inclination angle of the second clamp 8 is provided on the rotating disc 28. A rotating mechanism for adjusting the position of the supporting block 4 is provided inside the rotating ring 3;

[0030] The rotating mechanism includes a pressing rod 9. Four straight grooves 10 and four inclined grooves 11 are respectively formed on the inner wall of the rotating ring 3. And the four inclined grooves 11 are arranged between the four straight grooves 10. And the two ends of the inclined groove 11 are respectively connected to the upper and lower ends of the adjacent two straight grooves 10. A sunken clamping groove 12 is formed at the top end of the straight groove 10 and at the connection with the inclined groove 11, so that there is a step between the straight groove 10 and the clamping groove 12, and the connection between the clamping groove 12 and the inclined groove 11 is inclined;

[0031] A pair of fixing plates 13 are fixedly connected to the top of the base 1 and inside the rotating ring 3. A pressing block 14 is slidably connected between the fixing plates 13. The pressing rod 9 is slidably connected through the inner side wall of the pressing block 14. A pair of upper springs 15 are fixedly connected between the top of the base 1 and the bottom of the pressing block 14. A limiting disc 16 is fixedly connected to one end of the pressing rod 9 close to the fixing plate 2. A lower spring 17 is fixedly connected between the side wall of the limiting disc 16 and the side wall of the pressing block 14. And the other end of the pressing rod 9 is slidably connected inside one of the clamping grooves 12. A limiting mechanism for limiting the position of the rotating ring 3 is provided on the pressing block 14;

[0032] The limiting mechanism includes a U-shaped rod 21. Limiting holes 22 adapted to the pressing rod 9 are respectively formed on the side walls of the clamping grooves 12. Lower right-angle blocks 23 are fixedly connected to the side walls of the limiting disc 16. A sunken storage groove 24 is formed on the top of the pressing block 14 and beside the lower right-angle blocks 23. One end of the U-shaped rod 21 is slidably connected through the inside of the storage groove 24. The other end of the U-shaped rod 21 is fixedly connected to an upper right-angle block 25 that fits against the inclined surface of the lower right-angle block 23. Here, it should be noted that the distance that the pressing rod 9 is pushed out by pressing the U-shaped rod 21 can be limited according to the depth of the storage groove 24, ensuring that the pressing rod 9 does not slide out of the clamping groove 12 and preventing the normal operation of the rotating mechanism. A limiting spring 26 is fixedly connected between the bottom of the storage groove 24 and the bottom of the U-shaped rod 21;

[0033] When it is necessary to adjust the support position of the fixed bracket according to the layout of the pipelines in the utility tunnel, first press down the U-shaped rod 21 to slide in the receiving groove 24, and at the same time compress the limit spring 26, then drive the upper right-angle block 25 to slide downward to squeeze the inclined surface of the lower right-angle block 23, thereby pushing the limit disc 16 and the extrusion rod 9 to slide, so that the extrusion rod 9 slides out of the limit hole 22. At this time, the extrusion rod 9 is located in the card slot 12. Then, the pressing block 14 can be continuously pushed downward to slide between the fixed plates 13, and at the same time gradually squeeze the upper spring 15;

[0034] At this time, since there is a step between the card slot 12 and the straight groove 10, under the action of the thrust of the pressing block 14, the extrusion rod 9 will be driven to slide into the inclined groove 11. At the same time, the inclined groove 11 will push the extrusion rod 9 to slide outward, stretching the lower spring 17. At the same time, due to the positions of the pressing block 14 and the extrusion rod 9 being restricted by the fixed plates 13, the rotation ring 3 will be pushed to rotate through the movement of the extrusion rod 9 in the inclined groove 11, and at the same time drive the support block 4 to slide on the base 1. Then, when the support block 4 rotates a quarter of a circle, the pressing block 14 can be released. At this time, the extrusion rod 9 slides out of the inclined groove 11 and is located at the bottom of the straight groove 10. Then, under the elastic force of the upper spring 15, the pressing block 14 and the extrusion rod 9 are driven to slide upward for reset. Then, when the extrusion rod 9 slides to the card slot 12, the extrusion rod 9 will be pushed by the elastic force of the lower spring 17 to insert into the limit hole 22, thereby realizing the adjustment of the support direction of the second clamp 8 and being applicable to the support of inclined pipelines at different positions.

[0035] In order to prevent the support block 4 from hindering the installation of the fixed bracket in the utility tunnel, four fixing holes 18 for the screws to pass through are opened at the top of the base 1. Two of the fixing holes 18 are arranged on both sides of the support block 4, and the four fixing holes 18 are symmetrically arranged. By setting the fixing holes 18 diagonally, the support block 4 can be prevented from hindering the screws from passing through the fixing holes 18 and affecting the normal installation of the fixed bracket in the utility tunnel.

[0036] In order to be able to adjust the support direction of the first clamp 7 while the rotation ring 3 rotates, a connecting frame 19 is fixedly connected between the top of the rotation ring 3 and the top of the top plate 5, and a U-shaped groove 20 is opened at the top of the connecting frame 19. Through the setting of the connecting frame 19, while the rotation ring 3 rotates to adjust the support position of the second clamp 8, the top plate 5 can be driven to rotate, and then the telescopic rod 6 and the first clamp 7 are driven to rotate, so that the support position of the first clamp 7 is always the same as that of the second clamp 8, improving the convenience performance of the device. And through the U-shaped groove 20, the normal sliding of the U-shaped rod 21 can be prevented, and when the connecting frame 19 rotates above the pressing block 14, the position on the side opposite to the rotation direction can be pressed to adjust the position of the rotation ring 3.

[0037] In order to flexibly adjust the support angle of the second clamp 8 according to the inclination angle of the pipeline, the adjustment mechanism includes a lead screw 27. An eccentric hinge seat 29 is fixedly connected to the top of the rotating disk 28. A support rod 40 is hingedly connected to the inside of the hinge seat 29. The second clamp 8 is fixedly connected to the top end of the support rod 40. A base plate 30 is fixedly connected to the top of the rotating disk 28 and on the side away from the hinge seat 29. The lead screw 27 is rotatably connected between the hinge seat 29 and the base plate 30. The side wall of the lead screw 27 passes through the base plate 30 and is fixedly connected with a rotating block 31. A sliding block 32 is threadedly connected through the outer wall of the lead screw 27. A push rod 33 is hingedly connected between the top of the sliding block 32 and the bottom of the support rod 40. A guide rod 34 is fixedly connected between the side walls of the hinge seat 29 and the base plate 30 and is arranged through the inner side wall of the sliding block 32. Through the arrangement of the guide rod 34, it can play a guiding role during the process of the lead screw 27 driving the sliding block 32 to move, prevent the sliding block 32 from rotating together with the lead screw 27, and improve the stability during the operation of the device;

[0038] When it is necessary to adjust the inclination angle supported by the second clamp 8 according to the inclination angle of the installed pipeline, the lead screw 27 can be rotated by rotating the rotating block 31, and then the threadedly connected sliding block 32 is driven to move, thereby pushing or pulling the push rod 33 to drive the support rod 40 to rotate around the hinge joint with the hinge seat 29, realizing the adjustment of the inclination angle supported by the second clamp 8.

[0039] In order to further improve the application range of the device, a pair of sector-shaped rack rings 39 are fixedly connected to the top of the base 1 and outside the rotating ring 3, and the rack rings 39 are arranged diagonally. A toothed ring 35 meshing with the rack rings 39 is fixedly connected to the bottom of the rotating disk 28. A positioning mechanism for restricting the rotation position of the rotating disk 28 is provided on the support block 4;

[0040] The positioning mechanism includes a bolt 36. An indented positioning groove 37 is opened at the bottom of the support block 4 and beside the toothed ring 35. A toothed plate 38 meshing with the toothed ring 35 is provided beside the toothed ring 35. The bolt 36 is threadedly connected through the top of the support block 4, and the bottom of the bolt 36 is rotatably connected above the toothed plate 38;

[0041] When using the rotating mechanism to adjust the position of the second clamp 8, when it is necessary to change the inclination direction supported by the second clamp 8, first push the pressing block 14 to drive the support block 4 to move beside the rack ring 39. Subsequently, rotate the bolt 36 to move it spirally outwards, and at the same time, rotate the bolt 36 on the toothed plate 38 to drive the toothed plate 38 to move upwards, so that the toothed plate 38 slides into the positioning groove 37 and at the same time slides out of the meshing position with the toothed ring 35, thus releasing the restriction on the rotation position of the rotating disk 28. Subsequently, the pressing block 14 can be continuously pushed to drive the rotating ring 3 to rotate. At the same time, under the action of the meshing of the toothed ring 35 and the rack ring 39, the toothed ring 35 will be driven to rotate, and then the rotating disk 28 will be driven to rotate, realizing the adjustment of the support direction of the second clamp 8. After the adjustment is completed, screw the bolt 36 in the reverse direction to drive the toothed plate 38 to move downwards and slide into the meshing position with the toothed ring 35, so as to restrict the rotation position of the rotating disk 28.
