Description

Technical Field

[0001] This utility model relates to the field of pre-embedded channel technology, and in particular to an adjustable pre-embedded channel for tunnels. Background Technology

[0002] Pre-embedded channels and special T-bolts have become a common installation method for various pipelines and equipment in tunnels. Compared with the traditional method of drilling holes in the concrete surface, it causes less damage to the overall concrete structure of the tunnel and does not damage the tunnel's waterproof layer. However, because the pre-embedded channels need to be pre-positioned before concrete pouring and then embedded by concrete grouting, they are often subject to positional displacement due to the impact of concrete during the pouring process.

[0003] Chinese utility model patent CN211314281U discloses an adjustable pre-embedded channel for tunnels, comprising a pre-embedded channel body and a T-bolt disposed within a groove in the pre-embedded channel body. The bottom surface of the T-bolt head has several protruding structures, and the bottom surface of the C-shaped groove has several recessed structures. Within the contact area between the bottom surface of the bolt head and the bottom surface of the C-shaped groove, the protruding structures can be placed into their corresponding recessed structures. A washer and a clamping nut are provided on the bolt. The clamping nut engages with the bolt thread and presses the washer against the bottom surface of the C-shaped groove. When the longitudinal centerline of the C-shaped groove deviates from its intended installation position, fine-tuning can be achieved by moving the T-bolt to the left or right.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: During use, the device can only make minor adjustments to the T-bolt's movement to the left or right, limiting the adjustment range. When the embedded channel experiences angular displacement, it is difficult to effectively adjust the tilted T-bolt, affecting the positioning accuracy and mechanical stability of the connected structure. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an adjustable pre-embedded channel for tunnels.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable pre-embedded channel for tunnels, comprising several T-shaped pre-embedded parts, a pre-embedded channel body, and several T-shaped bolts disposed in the groove of the pre-embedded channel body. The lower end of each T-shaped pre-embedded part has a horizontally opening rotating hole. A rotating shaft is rotatably disposed within each of the rotating holes. Several connecting seats are spaced along the length of the rotating shaft. A connecting plate is disposed at the bottom of each of the connecting seats. A C-shaped plate is disposed on one side of the connecting plate. A worm gear is rotatably disposed within the C-shaped plate. A worm wheel ring is fixedly disposed on one of the T-shaped pre-embedded parts, concentrically arranged with the rotating shaft. The worm wheel ring cooperates with the worm gear. Sliding seats are horizontally slidably disposed at both ends of the connecting plate. The sliding direction of the sliding seats is perpendicular to the length direction of the connecting plate. A fixing unit is disposed on the sliding seat to fix the sliding seat. A sliding rod is vertically slidably disposed on the sliding seat. The top surface of the pre-embedded channel body is connected to the sliding rod. A driving unit is disposed on the pre-embedded channel body to drive its sliding.

[0007] By adopting the above technical solution, a rotating shaft, connecting seat, connecting plate, worm, and worm wheel ring are set up. When the angle of the pre-embedded channel body needs to be adjusted, the worm is rotated. Due to the cooperation between the worm wheel ring and the worm, the worm rotates around the axis of the worm wheel ring, driving the C-shaped plate, connecting plate, rotating shaft, sliding seat, and pre-embedded channel body to rotate around the axis of the rotating shaft, thereby adjusting the angle of the pre-embedded channel body. The pre-embedded channel body slides relative to the connecting plate, driving the sliding rod and sliding seat to move. Then, the position of the sliding seat is fixed by the fixing unit, thereby fixing the pre-embedded channel body and adjusting its horizontal position. The pre-embedded channel body is driven to slide vertically relative to the sliding seat by the driving unit, adjusting its vertical position. The angle and two directions of the pre-embedded channel body can be adjusted. T-bolts are set on the pre-embedded channel body, making the adjustment range of the T-bolts wide and ensuring that the structure connected to it meets the design requirements in terms of positioning accuracy and mechanical stability.

[0008] Furthermore, the connecting plate is provided with slide rails at both ends, the length direction of the slide rails is perpendicular to the length direction of the connecting plate, and the sliding seat is slidably connected to the corresponding slide rail through a slider.

[0009] By adopting the above technical solution and setting up a slide rail, the stability of the sliding seat is ensured.

[0010] Furthermore, the sliding seat has a screw hole that passes through the slider, and the fixing unit includes a first threaded rod that is spirally disposed in the screw hole. The lower end of the first threaded rod is provided with a first cross-shaped groove, and the pre-embedded channel body has an avoidance hole corresponding to the first threaded rod.

[0011] By adopting the above technical solution, a screw hole, a first threaded rod, and a clearance hole are provided. The operator inserts the end of a Phillips screwdriver into the first Phillips groove and then rotates the screwdriver to drive the first threaded rod. When the end of the first threaded rod moves away from the slide rail, the sliding seat and slider can slide. When the end of the first threaded rod abuts against the slide rail, the positions of the sliding seat and slider are fixed.

[0012] Furthermore, the connecting plate has a cut-off groove in the middle, and the driving unit includes a mounting frame set in the cut-off groove. A sliding block is slidably set in the mounting frame. The sliding direction of the sliding block is consistent with the length direction of the slide rail. A second threaded rod is rotatably set on the pre-embedded channel body. The length direction of the second threaded rod is consistent with the length direction of the sliding rod. The sliding block is helically connected to the second threaded rod through a threaded hole.

[0013] By adopting the above technical solution, a cut-off groove, a mounting frame, a sliding block, and a second threaded rod are set. When the second threaded rod is rotated, it moves relative to the sliding block, thereby driving the pre-embedded groove body and the sliding rod to move.

[0014] Furthermore, one end of the second threaded rod passes through the top of the pre-embedded channel body and is provided with a second cross groove.

[0015] By adopting the above technical solution and setting a second cross groove, the worker inserts the end of the cross screwdriver into the second cross groove, and then rotates the cross screwdriver to drive the second threaded rod to rotate.

[0016] Furthermore, the mounting frame has horizontally arranged protrusions on its two inner walls, the length direction of which is consistent with the length direction of the slide rail, and the sliding block has a groove corresponding to the protrusion, the groove being slidably connected to the corresponding protrusion.

[0017] By adopting the above technical solution and setting convex strips and grooves, the stability of the sliding block is ensured.

[0018] Furthermore, a third cross groove is provided at the lower end of the worm, and a waist-shaped hole is provided at the top of the pre-embedded channel body corresponding to the worm.

[0019] By adopting the above technical solution, a third cross groove and an oblong hole are set. The worker inserts the end of the cross screwdriver through the oblong hole into the third cross groove, and then rotates the cross screwdriver to drive the worm gear to rotate.

[0020] In summary, this utility model has the following beneficial effects: In this application, a rotating shaft, connecting seat, connecting plate, worm gear, and worm wheel ring are provided. When the angle of the pre-embedded channel body needs to be adjusted, the worm gear is rotated. Due to the cooperation between the worm wheel ring and the worm gear, the worm gear rotates around the axis of the worm wheel ring, causing the C-shaped plate, connecting plate, rotating shaft, sliding seat, and pre-embedded channel body to rotate around the axis of the rotating shaft, thereby adjusting the angle of the pre-embedded channel body. The pre-embedded channel body slides relative to the connecting plate, causing the sliding rod and sliding seat to move. Subsequently, the position of the sliding seat is fixed by the fixing unit, thereby fixing the pre-embedded channel body and adjusting its horizontal position. The pre-embedded channel body is driven to slide vertically relative to the sliding seat by the driving unit, adjusting its vertical position. The angle and two directions of the pre-embedded channel body can be adjusted. T-bolts are set on the pre-embedded channel body, making the adjustment range of the T-bolts wide, ensuring that the structure connected to it meets the design requirements in terms of positioning accuracy and mechanical stability.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-6 As shown in the figure, this application discloses an adjustable pre-embedded channel for tunnels, including a T-shaped pre-embedded part 10, a connecting plate 32, a fixing unit 60, a driving unit 70, a pre-embedded channel body 20, and a plurality of T-shaped bolts 21 disposed in the groove of the pre-embedded channel body 20. There are several T-shaped embedded parts 10. The horizontal section of the T-shaped embedded part 10 is embedded in the concrete. The lower end of the T-shaped embedded part 10 has a horizontal rotating hole. A rotating shaft 30 is rotatably installed in several rotating holes. Several connecting seats 31 are spaced along the length of the rotating shaft 30. A connecting plate 32 is connected to the bottom of several connecting seats 31. A C-shaped plate 40 is installed on one side of the connecting plate 32. A worm gear 41 is rotatably installed in the C-shaped plate 40. A worm wheel ring 42 is fixedly installed on one of the T-shaped embedded parts 10 and arranged concentrically with the rotating shaft 30. The worm wheel ring 42 cooperates with the worm gear 41. When the worm gear 41 is rotated, it rotates around the axis of the worm wheel ring 42, which drives the C-shaped plate 40, the connecting plate 32, and the rotating shaft 30 to rotate around the axis of the worm wheel ring 42. Both ends of the connecting plate 32 are horizontally slidably equipped with sliding seats 50. The sliding direction of the sliding seats 50 is perpendicular to the length direction of the connecting plate 32. The fixing unit 60 is installed on the sliding seats 50 to fix the sliding seats 50. A sliding rod 51 is vertically slidably installed on the sliding seats 50. The top surface of the pre-embedded channel body 20 is connected to the sliding rod 51. The driving unit 70 is installed on the pre-embedded channel body 20 to drive its sliding.

[0030] When the angle of the embedded channel body 20 needs to be adjusted, the worm 41 is rotated. Since the worm wheel ring 42 engages with the worm 41, the worm 41 rotates around the axis of the worm wheel ring 42, causing the C-shaped plate 40, connecting plate 32, rotating shaft 30, sliding seat 50, and embedded channel body 20 to rotate around the axis of the rotating shaft 30, thereby adjusting the angle of the embedded channel body 20. The embedded channel body 20 slides relative to the connecting plate 32, causing the sliding rod 51 and sliding seat 50 to move. Then, the position of the sliding seat 50 is fixed by the fixing unit 60, thereby fixing the embedded channel body 20 and adjusting its horizontal position. The embedded channel body 20 is driven to slide vertically relative to the sliding seat 50 by the driving unit 70, adjusting its vertical position. The angle and two directions of the pre-embedded channel body 20 can be adjusted. The T-bolt 21 is set on the pre-embedded channel body 20, which makes the adjustment range of the T-bolt 21 wide, ensuring that the structure connected to it meets the design requirements in terms of positioning accuracy and mechanical stability.

[0031] Specifically, the connecting plate 32 has slide rails 52 at both ends, with the length of the slide rails 52 perpendicular to the length of the connecting plate 32. The sliding seat 50 is slidably connected to the corresponding slide rail 52 via a slider, ensuring the stability of the sliding seat 50. The sliding seat 50 has a screw hole that passes through the slider. The fixing unit 60 includes a first threaded rod 61 screwed into the screw hole. The lower end of the first threaded rod 61 has a first cross-shaped groove 62. When the operator inserts the end of a Phillips screwdriver into the first cross-shaped groove and then rotates the screwdriver, the first threaded rod 61 will rotate. When the end of the first threaded rod 61 moves away from the slide rail 52, the sliding seat 50 and the slider can slide. When the end of the first threaded rod 61 abuts against the slide rail 52, the position of the sliding seat 50 and the slider is fixed. The pre-embedded channel body 20 has a clearance hole 22 corresponding to the first threaded rod 61, allowing the operator to easily insert the end of a Phillips screwdriver into the first cross-shaped groove from below the pre-embedded channel body 20.

[0032] During setup, a cut-off groove 33 is provided in the middle of the connecting plate 32. The drive unit 70 includes a mounting frame 71 disposed within the cut-off groove 33. The two sides of the mounting frame 71 are connected to the groove walls of the cut-off groove 33. A sliding block 72 is slidably disposed within the mounting frame 71, with the sliding direction of the sliding block 72 aligned with the length direction of the slide rail 52. A second threaded rod 73 is rotatably disposed on the pre-embedded channel body 20, with the length direction of the second threaded rod 73 aligned with the length direction of the sliding rod 51. The sliding block 72 is helically connected to the second threaded rod 73 through a threaded hole. When the second threaded rod 73 is rotated, it moves relative to the sliding block 72, causing the pre-embedded channel body 20 and the sliding rod 51 to move. When the pre-embedded channel body 20, the sliding rod 51, and the sliding seat 50 slide relative to the connecting plate 32, the movement of the second threaded rod 73 causes the sliding block 72 to slide within the mounting frame 71. This ensures that after the pre-embedded channel body 20 has been horizontally adjusted, the second threaded rod 73 can still be rotated to adjust the vertical position without being affected. One end of the second threaded rod 73 passes through the top of the pre-embedded channel body 20 and is provided with a second cross-shaped groove 74. The operator inserts the end of a Phillips screwdriver into the second cross-shaped groove 74, and then rotates the screwdriver to rotate the second threaded rod 73. The mounting frame 71 has horizontally arranged protrusions 75 on its opposite inner walls. The length direction of the protrusions 75 is consistent with the length direction of the slide rail 52. The sliding block 72 has corresponding grooves on the protrusions 75, and the grooves are slidably connected to the corresponding protrusions 75, ensuring the stability of the sliding block 72.

[0033] The worm gear 41 has a third cross groove 43 at its lower end, and the pre-embedded channel body 20 has a waist-shaped hole 23 at its top corresponding to the worm gear 41. The operator inserts the end of a Phillips screwdriver through the waist-shaped hole 23 into the third cross groove 43, and then rotates the screwdriver to rotate the worm gear 41. The waist-shaped hole 23 ensures that even after the pre-embedded channel body 20 moves horizontally, its top will not obstruct the operator's operation of the worm gear 41. A limiting ring is fixedly fitted onto the upper end of the sliding rod 51 to limit its sliding stroke.

[0034] The operating principle of an adjustable pre-embedded channel for tunnels in this embodiment is as follows:

[0035] The worker inserts the end of the Phillips screwdriver into the second Phillips groove 74, and then rotates the Phillips screwdriver to drive the second threaded rod 73 to rotate. When the second threaded rod 73 rotates, it drives the pre-embedded channel body 20 to move vertically.

[0036] Subsequently, the staff slides the pre-embedded channel body 20 horizontally, then inserts the end of the cross screwdriver through the clearance hole 22 into the first cross groove, and then rotates the cross screwdriver to drive the first threaded rod 61 to rotate. When the end of the first threaded rod 61 abuts against the slide rail 52, the position of the sliding seat 50 and the slider is fixed.

[0037] Next, the worker inserts a Phillips screwdriver through the oblong hole 23 into the third Phillips groove 43. Rotating the screwdriver drives the worm gear 41 to rotate. As the worm gear 41 rotates, it rotates around the axis of the worm wheel ring 42, causing the C-shaped plate 40, connecting plate 32, rotating shaft 30, sliding seat 50, and embedded channel body 20 to rotate around the axis of the rotating shaft 30, thereby adjusting the angle of the embedded channel body 20. The angle and two directions of the embedded channel body 20 are adjustable. T-bolts 21 are installed on the embedded channel body 20, allowing for a wide adjustment range and ensuring that the connected structure meets design requirements in terms of positioning accuracy and mechanical stability.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
