Description

Technical Field

[0001] The present invention relates to the technical field of tunnel engineering construction, and particularly relates to a positioning device for installing tunnel embedded parts. Background Art

[0002] In many fields such as bridges, tunnels, building construction, and subways, standardized embedded parts have been widely used. During the tunnel construction process, it is crucial to adopt reasonable and effective standardized solutions for the construction of embedded parts in a timely manner for the acceptance and operation safety of the tunnel structure after completion.

[0003] In the prior art, when installing an embedded pipe, positioning is usually required, and steel bar binding is mostly used as a fixing device. However, this method has some problems: 1. When using steel bar binding for the embedded pipe, the angle of the embedded pipe cannot be adjusted. If the wall surface is inclined, it is easy to cause deviation in the position of the embedded pipe.

[0004] 2. When positioning the embedded pipe, if two adjacent embedded pipes need to be butted, using steel bar binding for positioning may cause misalignment when the two embedded pipes are butted.

[0024] Embodiment Refer to Figures 1-9 For a tunnel embedded part installation and positioning device in this embodiment, first, fix the mounting frame 1 at a predetermined position in the tunnel to ensure stable installation. On the top of one side of the mounting frame 1, symmetrically install two connecting plates 2. On the side of the two connecting plates 2 close to each other, jointly and fixedly install a first connecting shaft 3. Subsequently, rotatably connect a U-shaped frame 4 to the first connecting shaft 3 so that the U-shaped frame 4 can rotate around the first connecting shaft 3. On one side of the U-shaped frame 4, fixedly install a mounting plate 5 for subsequent installation and positioning of the embedded part.

[0025] Install a mounting shaft 6 at the bottom of one side of the mounting frame 1, and symmetrically and rotatably sleeve two rotating rods 7 on the mounting shaft 6. Symmetrically open two guide grooves 8 at the bottom of one side of the mounting plate 5. Slide a guide plate 9 in each guide groove 8. One side of the two guide plates 9 extends to the outside of the mounting plate 5 and jointly and fixedly installs a connecting frame 10. Rotatably connect a second connecting shaft 11 through the connecting frame 10. One ends of the two rotating rods 7 are respectively fixedly connected to both ends of the second connecting shaft 11.

[0026] On one side of the connecting frame 10, a supporting slide plate 13 is fixedly installed. A positioning slide rail 12 is slidably connected to the supporting slide plate 13. The positioning slide rail 12 is fixedly installed at the bottom of one side of the mounting plate 5. A limiting component is installed on the supporting slide plate 13. The limiting component is connected to the second connecting shaft 11. Specifically, the limiting component includes two limiting rails 14 symmetrically and fixedly installed at the top of one side of the supporting slide plate 13. A limiting strip 15 is slidably connected in each limiting rail 14. The free ends of the two limiting strips 15 respectively extend to the outside of the corresponding limiting rails 14 and are jointly fixedly installed with a fixing plate 16. An arc-shaped rack 19 is fixedly installed on one side of the fixing plate 16. A positioning gear ring 18 is fixedly sleeved on the second connecting shaft 11. The arc-shaped rack 19 is movably engaged with the positioning gear ring 18. A limiting plate is fixedly installed on the inner wall of the top of one side of the connecting frame 10. A plug rod 20 is slidably connected through the limiting plate. The plug rod 20 penetrates through the supporting slide plate 13 and is slidably connected to the supporting slide plate 13. One end of the plug rod 20 is fixedly connected to the top of one side of the fixing plate 16, and the other end is movably clamped with a plurality of positioning grooves 17 formed on the positioning slide rail 12. A tension spring 21 is sleeved on the plug rod 20. The two ends of the tension spring 21 are respectively fixedly connected to one side of the fixing plate 16 and one side of the limiting plate.

[0027] When the angle of the mounting plate 5 needs to be adjusted, by rotating the two rotating rods 7, the second connecting shaft 11 and the connecting frame 10 are driven to perform an arc-shaped movement. Under the sliding cooperation of the two guide plates 9 and the corresponding guide grooves 8, the mounting plate 5 rotates and adjusts with the first connecting shaft 3 as the center. After the adjustment is completed, the fixing plate 16 is released. The elastic force of the tension spring 21 causes the fixing plate 16 to approach the second connecting shaft 11. The plug rod 20 is inserted into the corresponding positioning groove 17. At the same time, the arc-shaped rack 19 is engaged with the positioning gear ring 18 to realize the fixation of the mounting plate 5.

[0028] A first fixing seat 22 is fixedly installed at the top of the other side of the mounting plate 5. A sliding mechanism is installed at the bottom of the second fixing seat 23 so that it can slide on the mounting plate 5 and is located below the first fixing seat 22. Two binding steel belts 38 are symmetrically and fixedly installed on both the first fixing seat 22 and the second fixing seat 23. The binding steel belts 38 are connected by a fixing mechanism to fix the embedded part.

[0029] Connection ear plates 39 are respectively fixedly installed on the two binding steel belts 38. A T-shaped rod 40 is rotatably connected to one of the connection ear plates 39. A connection sleeve 41 is rotatably connected to the other connection ear plate 39. A fixing frame 42 is fixedly installed on one side of the connection sleeve 41.

[0030] On one inner wall of the fixing frame 42, a positioning screw 43 is rotatably connected, and a clamping plate 44 and a positioning nut 45 are sleeved on the positioning screw 43. The positioning nut 45 is fixedly installed on one side of the clamping plate 44 to ensure that the clamping plate 44 is slidably connected to the inner wall of one side of the fixing frame 42. A bayonet is opened on the clamping plate 44. The T-shaped rod 40 is passed through the bayonet and clamped with the clamping plate 44. After the embedded pipe is placed between the two binding steel belts 38, the fixing frame 42 and the T-shaped rod 40 are rotated to make the T-shaped rod 40 completely pass through the bayonet. Subsequently, the positioning screw 43 is rotated. Through its threaded drive with the positioning nut 45, the clamping plate 44 is driven to move towards the T-shaped rod 40. As the clamping plate 44 moves, the T-shaped rod 40 is pushed, thereby causing the two binding steel belts 38 to contract, tightly wrap and fix the embedded pipe.

[0031] A T-shaped limiting plate 47 is fixedly installed on one side of the fixing frame 42. At the same time, a limiting groove 46 is opened on one side of the T-shaped rod 40. After the T-shaped limiting plate 47 passes through the bayonet, one side of it extends into the limiting groove 46 and is slidably matched with the inner wall of the limiting groove 46. When the T-shaped rod 40 moves along with the clamping plate 44, the T-shaped limiting plate 47 and the limiting groove 46 maintain a sliding clamping relationship to prevent the T-shaped rod 40 from rotating and ensure the stable fixation of the binding steel belt 38.

[0032] Two moving rods 26 are symmetrically and fixedly installed on the top of the second fixing seat 23. The top ends of the moving rods 26 penetrate through the first fixing seat 22 and extend above it, and are slidably connected to the first fixing seat 22. The top ends of the moving rods 26 are fixedly connected to a pulling plate 27. Two positioning rods 28 are fixedly installed at the bottom of the pulling plate 27. The bottom ends of the positioning rods 28 are fixedly connected to both sides of the second fixing seat 23.

[0033] A plurality of inclined grooves 29 are opened at equal intervals on the sides of the two positioning rods 28 away from each other. Two clamping components are symmetrically installed on the other side of the mounting plate 5. Each clamping component includes a fixing ring 30. The positioning rod 28 penetrates through the fixing ring 30 and is slidably connected to its inner wall.

[0034] An elastic member is installed through the inner wall on one side of the fixing ring 30. The elastic member includes a support rod 31 and a braking spring 32. One end of the support rod 31 is fixedly connected to a wedge-shaped plate 33, and the other end passes through the fixing ring 30 and is sleeved with the braking spring 32. The two ends of the braking spring 32 are respectively fixedly connected to the other end of the support rod 31 and the fixing ring 30.

[0035] A rotating shaft 34 is rotatably embedded on the wedge-shaped plate 33. One side of it extends into the corresponding inclined groove 29 and is movably clamped with the inner wall of the inclined groove 29. The rotating shaft 34 is in contact with the bottom inclined surface of the inclined groove 29.

[0036] When the second fixed seat 23 moves upward, it drives the moving rod 26 and the positioning rod 28 to rise together. After the inclined surface rolls into contact with the rotating shaft 34, it pushes the wedge plate 33 to move outward, enabling the positioning rod 28 to rise smoothly.

[0037] When the positioning rod 28 descends to a position corresponding to the wedge plate 33, the braking spring 32 pulls the support rod 31, pushing the wedge plate 33 into the corresponding inclined surface groove 29 to form a stable clamping relationship, preventing the positioning rod 28 from continuing to descend, thereby ensuring two adjacent embedded pipes.

[0038] Limit grooves 24 are opened on both sides of the second fixed seat 23. Ensure that the size and shape of the limit grooves 24 match those of the limit sliding rails 25. Fix the two limit sliding rails 25 on the other side of the mounting plate 5 respectively, and ensure that the limit sliding rails 25 can smoothly penetrate and be slidably connected within the limit grooves 24. In this way, when the second fixed seat 23 needs to move, it can slide longitudinally along the limit sliding rails 25 to achieve vertical movement.

[0039] The longitudinal sliding of the second fixed seat 23 is limited by the limit sliding rails 25 to ensure that the second fixed seat 23 can move stably and accurately for accurate docking of two adjacent embedded pipes.

[0040] A transmission plate 35 is fixedly installed at the top of one side of the second fixed seat 23. Ensure that the transmission plate 35 can be firmly connected to the second fixed seat 23. One side of the transmission plate 35 penetrates the moving hole and extends to one side of the mounting plate 5.

[0041] An adjusting screw 36 is rotatably connected to the top of the positioning sliding rail 12. Ensure that the adjusting screw 36 can rotate freely without axial movement. An adjusting nut 37 is fixedly installed on the top side of the transmission plate 35 to tightly fix the adjusting nut 37 to the transmission plate 35.

[0042] The adjusting screw 36 penetrates through the adjusting nut 37 and the transmission plate 35 respectively and is threadedly connected to the adjusting nut 37. At the same time, ensure that the other end of the adjusting screw 36 is rotatably connected to one side of the mounting plate 5 for rotation operation.

[0043] When it is necessary to adjust the height of the second fixed seat 23 to dock adjacent embedded pipes, rotate the adjusting screw 36. Due to the threaded transmission between the adjusting screw 36 and the adjusting nut 37, rotating the adjusting screw 36 will drive the transmission plate 35 to move upward. The upward movement of the transmission plate 35 will then drive the second fixed seat 23 to move vertically upward along the limit sliding rails 25 until the required docking position is reached. The threaded transmission method not only ensures the stability and accuracy of the transmission but also has good self-locking performance, effectively preventing the separated problem of the embedded pipes after docking.

[0044] In the present invention, first, the mounting bracket 1 is fixed to the side wall of the tunnel by impact bolts. Then, the two rotating rods 7 can be rotated to drive the connecting frame 10 to perform an arc-shaped movement. At this time, under the sliding fit of the two guide plates 9 and the corresponding guide grooves 8, the mounting plate 5 can be driven to rotate, so that the mounting plate 5 rotates and adjusts with the first connecting shaft 3 as the center. Therefore, when positioning and installing the embedded pipe, the angle of the embedded pipe can be adjusted according to actual needs. And when the connecting frame 10 performs an arc-shaped movement, the support sliding plate 13 can slide on the positioning slide rail 12. So after the rotation adjustment of the mounting plate 5, the fixing plate 16 can be released. The tension spring 21 in the stressed state can drive the fixing plate 16 to approach the second connecting shaft 11, and then the insertion rod 20 can be inserted into the corresponding positioning groove 17. Synchronously, the arc-shaped rack 19 can be engaged with the positioning gear ring 18 to brake the positioning gear ring 18. In this way, after the angle adjustment of the mounting plate 5 is completed, the position of the mounting plate 5 can be limited and will not rotate randomly. Then, the two butt-jointed embedded pipes are respectively placed in the first fixing seat 22 and the second fixing seat 23. Then, the two T-shaped rods 40 and the two fixing frames 42 can be rotated so that the T-shaped rods 40 pass through the corresponding bayonet openings. At the same time, the T-shaped limiting plate 47 can be inserted into the corresponding limiting groove 46. Then, the positioning screw 43 can be rotated, and through the threaded transmission with the positioning nut 45, the clamping plate 44 can be driven to move. In this way, after the clamping plate 44 forms a clamping relationship with the T-shaped rod 40, the T-shaped rod 40 can be driven to move, so that the two binding steel belts 38 can be contracted to realize the positioning and installation of the embedded pipe. After the embedded pipe is tied and tightened, the adjusting screw 36 can be rotated, and under the threaded transmission action of the adjusting nut 37, the transmission plate 35 can be driven to move upward, so that the second fixing seat 23 can be driven to move upward to facilitate the butt-joint of two adjacent embedded pipes. And when the second fixing seat 23 moves upward, the two positioning rods 28 can be driven to move upward through the two moving rods 26. When the positioning rod 28 moves upward, after the inclined surface rolls into contact with the rotating shaft 34, the wedge plate 33 can be pushed to move outward from the inclined surface groove 29. Therefore, when the positioning rod 28 moves upward, it will not be hindered. When the positioning rod 28 moves downward, it will be limited by the wedge plate 33 to prevent the positioning rod 28 from moving downward. After the two adjacent embedded pipes are butt-jointed, the inclined surface groove 29 on the positioning rod 28 can correspond to the position of the wedge plate 33. The braking spring 32 in the stressed state can pull the support rod 31 to move, so that the wedge plate 33 can be moved into the corresponding inclined surface groove 29, thereby positioning and braking the positioning rod 28. At this time, the wedge plate 33 forms a stable clamping relationship with the corresponding inclined surface groove 29, so as to prevent the two butt-jointed embedded pipes from separating, and thus the accurate butt-joint of the two embedded pipes can be realized.

[0045] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention; without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
