Description

Technical Field

[0001] This invention relates to the field of tunnel construction, and in particular to an integral positioning clamp for reinforcing bars used in the waterstop of the low sidewall of a single-track railway tunnel. Background Technology

[0002] Waterstop strip for the low sidewall of a single-track railway tunnel is a waterproofing material specifically designed for the low sidewall of a single-track railway tunnel. It is mainly used to meet the waterproofing requirements of expansion joints.

[0003] During the installation of waterstops, positioning clamps are usually used to position the waterstops to ensure their stability after installation. The positioning clamps for waterstops used in the low sidewalls of single-track railway tunnels are usually made of welded steel bars and other profiles. When fixing the waterstops, the fixing plates located on both sides of the waterstops are used to achieve stable fixation of the waterstops.

[0004] Regarding the aforementioned technologies, the positioning clamp structure for waterstops used in the low sidewalls of single-track railway tunnels is usually fixed, which makes it difficult to make minor adjustments to the position of the waterstop and results in poor applicability. Summary of the Invention

[0005] To facilitate minor adjustments to the position of the waterstop after it has been positioned for the low sidewall of a single-track railway tunnel, thereby improving its applicability, this application provides an integral positioning clamp for the reinforcing steel bar of the waterstop for the low sidewall of a single-track railway tunnel.

[0006] This application provides a steel reinforcement positioning clamp for the waterstop strip of the low sidewall of a single-track railway tunnel, which adopts the following technical solution:

[0007] A rebar positioning clamp for a waterstop strip on a low sidewall of a single-track railway tunnel includes an installation plate, a fixing mechanism, and a positioning mechanism. The fixing mechanism is disposed on the installation plate and used to fix the position of the installation plate. The positioning mechanism includes a positioning fixing plate, a positioning adjusting plate, a positioning adjusting component, a positioning clamp, and a clamp moving component. The positioning fixing plate is installed on the positioning adjusting plate, and the positioning adjusting component is disposed on the positioning fixing plate and used to drive the positioning adjusting plate to move in the vertical direction. Two positioning clamps are arranged opposite each other, and the clamp moving component is used to drive the two positioning clamps to move towards or away from each other.

[0008] By adopting the above technical solution, when fixing the waterstop of the low sidewall of a single-track railway tunnel, the position of the mounting plate is first fixed by the fixing mechanism. Then, the clamping plate movement assembly drives the two positioning clamps to move towards each other to clamp and fix both sides of the waterstop, which helps to ensure the stability of the waterstop's position. At this time, the positioning adjustment assembly drives the positioning adjustment plate to move in the vertical direction, which facilitates the fine adjustment of the vertical position of the waterstop. This makes it easy for the waterstop to adapt to different construction conditions and has strong applicability.

[0009] Optionally, the positioning adjustment assembly includes a positioning adjustment screw, the positioning adjustment plate has a positioning groove extending in the vertical direction, the positioning fixing plate is fixedly installed with a positioning slider, the positioning slider slides and engages in the positioning groove, the positioning adjustment screw is vertically rotatably installed on the positioning fixing plate, and the positioning adjustment screw passes through and is threaded into the positioning adjustment plate.

[0010] By adopting the above technical solution, when the positioning and adjusting screw is rotated, the positioning slider moves vertically due to the threaded engagement with the adjusting screw and the limiting action of the positioning groove, which is convenient and stable.

[0011] Optionally, the positioning and fixing plate is installed on the mounting plate via a connecting assembly. The connecting assembly includes a connecting fixing rod, a connecting sliding rod, a connecting reset member, and a connecting ball. The connecting fixing rod is fixedly installed on the positioning and fixing plate. One end of the connecting fixing rod has a connecting movable groove, and the outer side of the connecting fixing rod has a connecting fixing hole communicating with the connecting movable groove. The connecting ball is located in the connecting fixing hole, and the diameter of the connecting ball is larger than the diameter of the connecting fixing hole. The connecting sliding rod slides within the connecting movable groove, and the outer side of the connecting sliding rod has a connecting receiving groove for accommodating the connecting ball. The connecting reset member is used to move the connecting sliding rod away from the connecting fixing rod. When the connecting sliding rod abuts against the connecting ball, the outer side of the connecting ball protrudes out of the fixing hole. The mounting plate has a mounting insertion hole for inserting and engaging with the connecting fixing rod.

[0012] By adopting the above technical solution, when the connecting sliding rod is pressed so that the receiving groove is aligned with the fixing hole, the connecting fixing rod is inserted into the mounting hole. During the insertion process, the connecting ball is retracted into the receiving groove under the action of the component force. After the connecting fixing rod is inserted into the mounting hole, the connecting sliding rod is released. The connecting sliding rod is reset under the elastic force of the connecting reset component, thereby pushing out the connecting ball. Thus, the fixing between the connecting fixing rod and the mounting plate is achieved under the limiting action of the connecting ball, making the connection between the positioning fixing plate and the mounting plate convenient and quick.

[0013] Optionally, the mounting hole includes a sliding section and a limiting section, the limiting section being formed on the inner wall of the sliding section, and the limiting section being used to accommodate the connecting ball.

[0014] By adopting the above technical solution, the setting of the limiting section plays a further limiting role in the position of the connecting ball, which helps to further ensure the connection stability between the positioning fixing plate and the mounting plate.

[0015] Optionally, the mounting plate is fixedly mounted with a fixed connecting sleeve, the mounting hole is opened in the fixed connecting sleeve, and the connecting reset component includes a connecting spring, one end of which is connected to the wall of the connecting movable groove and the other end is connected to the connecting sliding rod.

[0016] By adopting the above technical solution, the setting of the connecting spring makes the reset structure of the connecting sliding rod simple and convenient, and the setting of the fixed connecting sleeve facilitates the processing and forming of the mounting hole.

[0017] Optionally, the clamping plate motion assembly includes a clamping plate rotating seat, a clamping plate rotating component, a bidirectional lead screw, and a clamping plate driving component. The clamping plate rotating seat is rotatably mounted on the positioning adjustment plate. The clamping plate rotating component is used to drive the clamping plate rotating seat to rotate around its own axis. The bidirectional lead screw is rotatably mounted on the clamping plate rotating seat. The two ends of the bidirectional lead screw with opposite thread directions are respectively threaded and engaged with two positioning clamping plates. The two positioning clamping plates are slidably engaged with the clamping plate rotating seat. The clamping plate driving component is used to drive the bidirectional lead screw to rotate.

[0018] By adopting the above technical solution, when the clamping plate drive component drives the bidirectional lead screw to rotate, the two positioning clamping plates move towards or away from each other due to the threaded engagement with the bidirectional lead screw and the limiting action of the clamping plate rotating seat, which is convenient and stable. In addition, the rotation of the clamping plate rotating seat driven by the clamping plate drive component facilitates the adjustment of the horizontal angle of the waterstop after it is clamped and fixed, thereby facilitating the bending installation of the waterstop. It also facilitates better fitting of the structural deformation parts according to different construction conditions, has strong applicability, and helps to better ensure the waterproof effect of the waterstop after installation under different construction conditions.

[0019] Optionally, the clamping plate rotating component includes a clamping plate rotating rod, a clamping plate rotating worm wheel, and a clamping plate rotating worm. The clamping plate rotating rod is coaxially fixedly installed on the clamping plate rotating seat, and the clamping plate rotating rod is rotatably installed on the positioning adjustment plate. The clamping plate rotating worm wheel is coaxially fixedly installed on the clamping plate rotating rod, and the clamping plate rotating worm is rotatably installed on the positioning adjustment plate and meshes with the clamping plate rotating worm wheel.

[0020] By adopting the above technical solution, when the clamping plate rotates the worm gear, the clamping plate rotating worm wheel drives the clamping plate rotating seat to rotate together. The self-locking effect between the clamping plate rotating worm wheel and the clamping plate rotating worm helps to ensure the stability of the position of the clamping plate rotating seat after rotation.

[0021] Optionally, the clamping plate driving component includes a driving worm, a driving worm wheel, a driving gear, a rack sleeve, and a driven gear. The driven gear is coaxially fixedly mounted on a two-way lead screw. The rack sleeve meshes with the driven gear. The rack sleeve is fitted onto and slidably engages with the clamping plate rotating rod. The driving gear is rotatably mounted on a positioning adjustment plate and meshes with the rack sleeve. The driving worm wheel is coaxially fixedly mounted on the driving gear. The driving worm is rotatably mounted on the positioning adjustment plate and meshes with the driving worm wheel.

[0022] By adopting the above technical solution, when the driving worm is rotated by force, the driving worm wheel drives the driving rack to rotate together. The rack sleeve moves along the axis of the rotating rod of the clamp due to the meshing with the driving gear, which in turn drives the driven gear and the double-acting screw to rotate together. The self-locking effect between the driving worm and the driving worm wheel helps to ensure the stability of the position of the double-acting screw after rotation.

[0023] Optionally, the positioning adjustment plate is equipped with a protective shell, which covers the clamping plate rotating component and the clamping plate driving component. One end of the clamping plate rotating worm and the driving worm are both inserted through and rotatably fitted into the protective shell. A handle is fixedly installed on one end of the clamping plate rotating worm and the driving worm that are inserted through the protective shell.

[0024] By adopting the above technical solution, the protective shell facilitates the protection of the covered components, making the covered components less susceptible to external influences and helping to ensure the transmission stability between the various drive components. The handle facilitates the application of force by construction personnel to rotate the rotating worm and the drive worm.

[0025] Optionally, the fixing mechanism includes a fixing plate, a fixing screw, and a fixing clamp. The fixing plate is fixedly installed on the mounting plate, the fixing screw is rotatably installed on the fixing plate, the fixing screw passes through and is threaded into the fixing clamp, and the fixing clamp is slidably fitted onto the mounting plate.

[0026] By adopting the above technical solution, when the frame or cross rib is located between the fixed plate and the fixed clamp, by applying force to rotate the fixed screw, the fixed clamp moves towards the fixed plate due to the threaded engagement with the fixed screw and the limiting action of the mounting plate, thereby fixing the mounting plate in a convenient and quick manner.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. After the waterstop is clamped and fixed by two positioning clamps, the positioning adjustment plate is driven by the positioning adjustment component to move in the vertical direction, which facilitates the fine adjustment of the vertical position of the waterstop. This makes the waterstop adaptable to different construction conditions and has strong applicability.

[0029] 2. After the connecting fixing rod is inserted into the mounting hole, the connecting sliding rod is released. The connecting sliding rod is reset under the elastic force of the connecting reset component, which in turn pushes out the connecting ball. Thus, the connecting fixing rod and the mounting plate are fixed under the limiting action of the connecting ball. The connection between the positioning fixing plate and the mounting plate is convenient and quick.

[0030] 3. The rotation of the clamping plate rotating seat driven by the clamping plate rotating component facilitates the adjustment of the horizontal angle of the waterstop after it is clamped and fixed, thereby facilitating the bending installation of the waterstop. This allows for better fitting of the deformed parts of the structure according to different construction conditions, making it highly applicable and helping to better ensure the waterproof effect of the waterstop after installation under different construction conditions.

[0038] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0039] This application discloses an integral positioning clamp for reinforcing bars used in the waterstop strip of the low sidewall of a single-track railway tunnel. (Refer to...) Figure 1 The integral positioning clamp for the waterstop strip of the low side wall of a single-track railway tunnel includes an installation plate 1, a fixing mechanism, and a positioning mechanism. The installation plate 1 is roughly rectangular. In this embodiment, the length direction of the installation plate 1 is the x-axis direction, the width direction is the y-axis direction, and the height direction is the z-axis direction. The fixing mechanism is located on the installation plate 1 and is used to fix the installation plate 1.

[0040] Continue to refer to Figure 1 Specifically, there are two sets of fixing mechanisms. Both sets of fixing mechanisms are located at the bottom of the mounting plate 1 and are respectively set close to both sides of the mounting plate 1 along its length. The fixing mechanism includes a fixing plate 2, a fixing screw 3, and a fixing clamp 4. The fixing plate 2 is fixedly installed at the bottom of the mounting plate 1. The fixing screw 3 is set along the x-axis and rotatably installed on the fixing plate 2. The fixing screw 3 passes through and is threaded into the fixing clamp 4. The top of the fixing clamp 4 abuts against the bottom of the mounting plate 1 and slides with the mounting plate 1. So that when the frame or the cross rib is located between the fixing plate 2 and the fixing clamp 4, by applying force to rotate the fixing screw 3, the fixing clamp 4 moves towards the fixing plate 2. Thus, the fixing clamp 4 and the fixing plate 2 clamp the frame or the cross rib to fix the position of the mounting plate 1.

[0041] Reference Figure 2 and Figure 3The positioning mechanism includes a positioning fixing plate 5, a positioning adjusting plate 6, a positioning adjusting component, a positioning clamping plate 7, and a clamping plate moving component. The positioning fixing plate 5 is installed on the mounting plate 1 via a connecting component. Two sets of connecting components are provided and are respectively arranged on both sides close to the length direction of the positioning fixing plate 5. Specifically, the connecting component includes a connecting fixing rod 8, a connecting sliding rod 9, a connecting reset component, and a connecting ball 11. The connecting fixing rod 8 is arranged along the x-axis and fixedly installed on the positioning fixing plate 5. One end of the connecting fixing rod 8 is provided with a connecting movable groove 12. The connecting movable groove 12 includes a connecting section 121 and a movable section 122. The movable section 122 is opened in the connecting fixing rod 8, and the connecting section 121 is opened in the groove wall of the movable section 122 away from its own groove opening. The cross-sectional dimension of the connecting section 121 is smaller than the cross-sectional dimension of the movable section 122.

[0042] Reference Figure 2 The connecting sliding rod 9 includes a movable part 901 and a connecting part 902 fixedly installed at one end of the movable part 901. The connecting part 902 and the movable part 901 are respectively slidably fitted within the connecting section 121 and the movable section 122. The connecting reset member includes a connecting spring 10, which is sleeved outside the connecting part 902. One end of the connecting spring 10 is connected to the groove wall of the movable section 122 away from its own groove opening, and the other end is connected to the movable part 901, so that the connecting sliding rod 9 moves away from the connecting section 121 under the elastic force of the connecting spring 10.

[0043] Continue to refer to Figure 2 The connecting fixing rod 8 has a connecting fixing hole 13 on its outer side that communicates with the connecting movable groove 12. Multiple connecting fixing holes 13 are evenly distributed around the axis of the connecting fixing rod 8. Multiple connecting balls 11 are arranged one-to-one with the connecting fixing holes 13. Each connecting ball 11 is located in its respective connecting fixing hole 13 and the diameter of each connecting ball 11 is larger than the diameter of the connecting fixing hole 13. The connecting part 902 of the connecting sliding rod 9 has a connecting receiving groove 14 on its outer side for receiving the connecting balls 11. Normally, the outer side of the connecting part 902 presses against the connecting balls 11, and the free end of the connecting balls 11 protrudes out of the connecting fixing hole 13. When the connecting sliding rod 9 is pressed so that the position of the connecting receiving groove 14 corresponds to the position of the connecting fixing hole 13, the connecting balls 11 are received into the connecting receiving groove 14 under the action of a component force.

[0044] Continue to refer to Figure 2The mounting plate 1 is fixedly mounted with a fixing connecting sleeve 15. There are two fixing connecting sleeves 15 corresponding to the connecting fixing rod 8. The fixing connecting sleeve 15 has a mounting hole 16, which includes a sliding section 161 and a limiting section 162. The limiting section 162 is opened on the inner wall of the sliding section 161 and is used to accommodate the connecting ball 11. The connecting fixing rod 8 slides and engages with the sliding section 161. When the connecting sliding rod 9 is pressed and the connecting fixing rod 8 slides to the position where the connecting ball 11 is directly opposite the limiting section 162, the connecting sliding rod 9 is released. Under the pushing action of the connecting sliding rod 9, the connecting ball 11 is inserted into the limiting section 162, thereby achieving stable fixation between the mounting plate 1 and the positioning fixing plate 5.

[0045] Reference Figure 3 and Figure 4 The positioning adjustment assembly includes a positioning adjustment screw 17, a positioning fixing plate 5 with a positioning slider 18 arranged vertically, a positioning adjustment plate 6 with a positioning groove 19 extending vertically, the positioning slider 18 slidingly fitting within the positioning groove 19, the positioning adjustment screw 17 being vertically rotatably mounted on the positioning fixing plate 5, and the positioning adjustment screw 17 passing through and threadedly fitting into the positioning adjustment plate 6, so that when the positioning adjustment screw 17 rotates, the positioning adjustment plate 6 moves vertically, thereby facilitating fine adjustment of the vertical position of the waterstop after it is fixed. To facilitate the application of force to rotate the positioning adjustment screw 17, a gripping part 20 is fixedly installed on the top of the positioning adjustment screw 17.

[0046] Reference Figure 4 and Figure 5 The clamping plate moving assembly includes a clamping plate rotating seat 21, a clamping plate rotating component, a bidirectional lead screw 22, and a clamping plate driving component. The clamping plate rotating seat 21 is rotatably mounted on the bottom of the positioning adjustment plate 6. Two positioning clamping plates 7 are arranged opposite each other, and the tops of the two positioning clamping plates 7 abut against and slide against the clamping plate rotating seat 21. The bidirectional lead screw 22 is rotatably mounted on the clamping plate rotating seat 21. The two ends of the bidirectional lead screw 22 with opposite threads are respectively threaded through and threaded into the two positioning clamping plates 7, so that when the bidirectional lead screw 22 rotates, the two positioning clamping plates 7 move in a direction that is closer to or further away from each other, thereby facilitating the fixing or unfixing of the waterstop when it is located between the two positioning clamping plates 7.

[0047] Reference Figure 4The clamping plate rotating component is used to drive the clamping plate rotating seat 21 to rotate around its own axis. Specifically, the clamping plate rotating component includes a clamping plate rotating rod 23, a clamping plate rotating worm wheel 24, and a clamping plate rotating worm 25. The clamping plate rotating rod 23 is coaxially fixedly installed on the top of the clamping plate rotating seat 21 and rotatably installed on the positioning adjustment plate 6. The clamping plate rotating worm wheel 24 is coaxially fixedly installed on the clamping plate rotating rod 23, and the clamping plate rotating worm 25 is rotatably installed on the positioning adjustment plate 6 and meshes with the clamping plate rotating worm wheel 24. When the clamping plate rotating worm 25 rotates, the clamping plate rotating worm wheel 24 drives the clamping plate rotating rod 23 and the clamping plate rotating seat 21 to rotate together. This facilitates the adjustment of the horizontal angle of the waterstop after it is clamped and fixed, and facilitates the bending installation of the waterstop. It also facilitates better fitting of the deformed parts of the structure according to different construction conditions, which is beneficial to ensuring the waterproof effect of the waterstop after installation.

[0048] Reference Figure 4 and Figure 5 The clamping plate drive assembly includes a drive worm 26, a drive worm wheel 27, a drive gear 28, a rack sleeve 29, and a driven gear 30. The driven gear 30 is coaxially fixedly mounted on the double-acting screw 22. The outer teeth of the rack sleeve 29 mesh with the driven gear 30. The rack sleeve 29 is coaxially fitted and slidably engaged with the clamping plate rotating rod 23. The drive gear 28 is rotatably mounted on the positioning adjustment plate 6 and meshes with the outer teeth of the rack sleeve 29. The drive worm wheel 27 is coaxially fixedly mounted... Drive worm 26 is rotatably mounted on positioning adjustment plate 6 and meshes with drive worm wheel 27, so that when drive worm 26 rotates, drive worm wheel 27 drives drive gear 28 to rotate together, which in turn drives rack sleeve 29 to drive driven gear 30 and double-acting screw 22 to rotate together. This arrangement ensures that the rotation of clamping plate rotating seat 21 and double-acting screw 22 does not interfere with each other, and helps to ensure the stability of the position of clamping plate rotating seat 21 and double-acting screw 22 after rotation.

[0049] Reference Figure 1 and Figure 4 To further ensure the stability of the clamping plate rotating seat 21 and the bidirectional lead screw 22 during rotation, the positioning adjustment plate 6 is equipped with a protective shell 31. The protective shell 31 covers the clamping plate rotating component and the clamping plate driving component. One end of the clamping plate rotating worm 25 and the driving worm 26 are both inserted through and rotated in the protective shell 31, so that the protective shell 31 can protect the clamping plate rotating component and the clamping plate driving component. The ends of the clamping plate rotating worm 25 and the driving worm 26 that are inserted through the protective shell 31 are both fixedly equipped with handles 32, so as to apply force to achieve stable rotation of the rotating worm and the driving worm 26.

[0050] The implementation principle of the steel reinforcement integral positioning clamp for the waterstop of the low sidewall of a single-track railway tunnel according to an embodiment of this application is as follows: When it is necessary to fix the waterstop of the low sidewall of a single-track railway tunnel, firstly, the rotation of the fixing screw 3 causes the fixing plate 2 and the fixing clamp 4 to clamp the frame or horizontal reinforcement, thereby fixing the position of the mounting plate 1. Then, the rotation of the driving worm 26 drives the two positioning clamps 7 to move towards each other, thereby clamping and fixing both sides of the waterstop, which helps to ensure the stability of the position of the waterstop. At this time, the rotation of the positioning adjustment screw 17 drives the positioning adjustment plate 6 to move in the vertical direction, which facilitates the slight adjustment of the vertical position of the waterstop. The rotation of the clamp rotation worm 25 facilitates the adjustment of the horizontal angle of the waterstop, thus making the waterstop adaptable to different construction conditions and having strong applicability.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
