Description

Technical Field

[0001] This application belongs to the field of tooling technology, and more specifically, it relates to a tooling device for shaping the connecting groove of a horizontal drainage pipe on a low side wall. Background Technology

[0002] In tunnel construction, the low sidewall (also known as the small sidewall) is a common term used by construction units to refer to the transition section between the invert arch and the secondary lining. Its purpose is to facilitate the positioning of the secondary lining trolley, reduce problems such as grout leakage and misalignment during concrete pouring, and improve overall shear resistance by staggering the construction joint positions.

[0003] During the pouring of the low side wall, a horizontal drainage pipe is pre-embedded inside, which then connects to other external pipes. To facilitate the connection between the horizontal drainage pipe and the external pipes, a groove is reserved at the intersection of the horizontal drainage pipe and the low side wall, so that a certain length of the top of the horizontal drainage pipe protrudes.

[0004] In existing technology, in order to reserve the aforementioned groove, positioning holes need to be made on the template first, then the shaping fixture is inserted into the positioning holes, and finally welded and fixed. After the pouring is completed, in order to facilitate the forward sliding of the template, the welded and fixed shaping fixture needs to be removed first, otherwise the connecting groove will be damaged. However, fixing and removing the fixture not only wastes construction time and reduces construction efficiency, but repeated welding and removal may also damage the template. Utility Model Content

[0005] The purpose of this application is to provide a connecting groove shaping device for horizontal drainage pipes on low side walls, so as to improve construction efficiency and prevent damage to the formwork.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A device for shaping the connecting groove of a horizontal drainage pipe on a low-profile wall is provided, comprising a positioning hole, a shaping fixture, multiple positioning elements, and multiple limiting mechanisms. The positioning hole is formed on a template; the shaping fixture is adapted to the shape of the positioning hole, inserted into the positioning hole, and the outer wall of the shaping fixture seals against the side wall of the positioning hole. The shaping fixture has a first position extending partially to the outside of the template and a second position retracting to the inside of the outer wall of the template. Multiple positioning elements are rotatably disposed on one side of the shaping fixture along any rotating axis. The component has a blocking end that is far from the rotating shaft relative to the rest of the positioning component. When the shaping fixture is in the first position, the positioning component is in its natural state, and the blocking end blocks the sliding path of the shaping fixture and abuts against the top of the shaping fixture. Furthermore, the positioning component can release its obstruction of the sliding path of the shaping fixture by rotation. A plurality of limiting mechanisms correspond one-to-one with the positioning component. The limiting mechanism is placed on the rotation path of the corresponding blocking end of the positioning component, and when the positioning component is in its natural state, the limiting mechanism abuts against the top of the corresponding blocking end of the positioning component.

[0007] In one possible implementation, the positioning hole is a square hole, the shaping fixture is box-shaped, the bottom of the shaping fixture is sealed, and the bottom surface of the shaping fixture is provided with a clearance hole. The top of the shaping fixture is open, a sealing ring is provided on the side wall of the positioning hole, and the outer wall of the shaping fixture abuts against the sealing ring.

[0008] In one possible implementation, the top of the shaping fixture is provided with a mounting ring, the mounting ring is provided with multiple guide holes, and multiple guide rods are provided on the outside of the positioning holes. The guide rods correspond one-to-one with the guide holes and are inserted into the corresponding guide holes.

[0009] In one possible implementation, a return spring is provided between the mounting ring and the template, and when the return spring is in its natural state, the shaping fixture is in the second position.

[0010] In one possible implementation, the positioning element includes two elements, which are respectively disposed on both sides of the shaping fixture; two support plates are arranged at intervals on the same side of each positioning element, and a rotating shaft is provided between the support plates, with the positioning element fixed on the rotating shaft.

[0011] In one possible implementation, a torsion spring is provided between the positioning member and any of the support plates on the same side, and the positioning member is in its natural state when the torsion spring is in its natural state.

[0012] In one possible implementation, a crank handle is connected to each of the rotating shafts, and the crank handle is used to drive the rotating shaft to rotate.

[0013] In one possible implementation, the positioning element includes either a cam or a positioning rod; when the positioning element is a cam, the cam's protrusion is a blocking end, and the cam's base circle is coaxially arranged with the rotation axis; when the positioning element is a positioning rod, one end of the positioning rod is fixed to the rotation axis, and the other end of the positioning rod is the blocking end.

[0014] In one possible implementation, the limiting mechanism includes a limiting rod, the two ends of which are respectively fixed to two support plates on the same side.

[0015] In one possible implementation, the limiting mechanism includes a limiting groove formed on one of the support plates, a portion of the blocking end being disposed within the limiting groove, and when the positioning member is in its natural state, the sidewall of the limiting groove abuts against the top wall of the blocking end.

[0016] The beneficial effects of the connecting groove shaping device for the transverse drainage pipe of the low side wall provided in this application are as follows: Compared with the prior art, this application uses a shaping fixture with switchable positions and a rotatable positioning component. By pressing the shaping fixture, the fixture is partially extended to the outside of the template and enters the first position. At this time, the connecting groove for the transverse drainage pipe of the low side wall will be reserved during pouring. At this time, the positioning component automatically blocks the sliding of the shaping fixture. At the same time, by setting a limiting mechanism, the positioning component is prevented from rotating, so that the positioning component effectively fixes the shaping fixture and ensures the stability of pouring. By rotating the positioning component, the obstruction is released, which facilitates the sliding of the shaping fixture to the second position, so that the shaping fixture is retracted to the inner side of the outer wall of the template, preventing the presence of the shaping fixture from interfering with the advancement of the template. The cooperation between the shaping fixture and the rotatable positioning component realizes the function of quick fixing and release of the shaping fixture, avoids welding and dismantling processes, improves construction efficiency, reduces template damage, and ensures the quality of groove forming.

[0037] The connecting groove shaping device for the horizontal drainage pipe of the low side wall provided in this application will now be described.

[0038] Please refer to the following: Figures 1 to 8The connecting groove shaping device for the horizontal drainage pipe of the low side wall includes a positioning hole, a shaping fixture 2, multiple positioning elements 3, and multiple limiting mechanisms. The positioning hole is formed on the template 1. The shaping fixture 2 is adapted to the shape of the positioning hole, inserted into the positioning hole, and its outer wall seals against the side wall of the positioning hole. The shaping fixture 2 has a first position extending partially to the outside of the template 1 and a second position retracting to the inside of the outer wall of the template 1. Multiple positioning elements 3 are rotatably positioned on one side of the shaping fixture 2 along any axis of rotation. Each positioning element 3 has a blocking end 301 that is far from the axis of rotation relative to the rest of the positioning element 3. When the shaping fixture 2 is in the first position, the positioning element 3 is in its natural state, with the blocking end 301 blocking the sliding path of the shaping fixture 2 and pressing against the top of the shaping fixture 2. Furthermore, the positioning element 3 can release its obstruction of the sliding path of the shaping fixture 2 due to rotation. Multiple limiting mechanisms correspond one-to-one with the positioning element 3. The limiting mechanism is placed on the rotation path of the blocking end 301 of the corresponding positioning element 3. When the positioning element 3 is in its natural state, the limiting mechanism abuts against the top of the blocking end 301 of the corresponding positioning element 3.

[0039] The beneficial effects of the connecting groove shaping device for the transverse drainage pipe of the low side wall provided in this embodiment are as follows: Compared with the prior art, the connecting groove shaping device for the transverse drainage pipe of the low side wall provided in this embodiment uses a shaping fixture 2 with switchable working positions and a rotatable positioning component 3. By pressing the shaping fixture 2, the shaping fixture 2 is partially extended to the outside of the template 1 and enters the first working position. At this time, the connecting groove for the transverse drainage pipe of the low side wall will be reserved during pouring. At this time, the positioning component 3 automatically blocks the sliding of the shaping fixture 2. At the same time, by setting a limiting mechanism, the positioning component 3 is prevented from rotating, so that the positioning component 3 effectively fixes the shaping fixture 2 and ensures the stability of pouring. By rotating the positioning component 3, the obstruction is released, which facilitates the sliding of the shaping fixture 2 to the second working position, so that the shaping fixture 2 is retracted to the inner side of the outer wall of the template 1, preventing the presence of the shaping fixture 2 from interfering with the advancement of the template 1. The cooperation between the shaping fixture 2 and the rotatable positioning component 3 realizes the function of quick fixing and release of the shaping fixture 2, avoids welding and dismantling processes, improves construction efficiency, reduces damage to the template 1, and ensures the quality of groove forming.

[0040] In this embodiment, the positioning hole is a square hole, the shaping fixture 2 is box-shaped, the bottom of the shaping fixture 2 is sealed, and a clearance hole is provided on the bottom surface of the shaping fixture 2. The top of the shaping fixture 2 is open, and a sealing ring is provided on the side wall of the positioning hole. The outer wall of the shaping fixture 2 abuts against the sealing ring. The sealing ring ensures that when the invert arch is poured, the material will not leak from the gap between the shaping fixture 2 and the positioning hole into the mold plate 1. Of course, the shape of the positioning hole is not limited to square; it can also be circular, polygonal, or other shapes. After all, the purpose of the reserved connecting groove is only to expose part of the drainage pipe, and there are no specific requirements for the shape of the connecting groove.

[0041] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the top of the shaping fixture 2 is provided with a mounting ring 201, which has multiple guide holes. Multiple guide rods 101 are located outside the positioning holes, each corresponding to a guide hole. The guide rods 101 are inserted into their respective guide holes. The cooperation between the guide rods 101 and the guide holes ensures the straightness of the shaping fixture 2 during movement, preventing skewing, improving the positioning accuracy of the fixture, and preventing groove deformation or grout leakage due to offset. The arrangement of the mounting ring 201 provides space for the guide holes.

[0042] In addition, a return spring 102 is provided between the mounting ring 201 and the template 1. When the return spring 102 is in its natural state, the shaping fixture 2 is in the second position. In actual use, the shaping fixture 2 is initially in the second position. When the shaping fixture 2 is pressed down, the mounting ring 201 pushes the positioning member 3 to rotate, releasing the obstruction to the sliding path of the shaping fixture 2. At this time, the spring is compressed and stores energy until the shaping fixture 2 enters the first position, resetting the positioning member 3. Due to the obstruction of the limiting mechanism, the positioning member 3 cannot continue to rotate in the direction of rotation during reset. At this time, the shaping fixture 2 is fixed relative to the template 1 under the dual action of the positioning member 3 and the spring. When the pouring is completed, the positioning member 3 rotates in the direction of rotation when the shaping fixture 2 slides down, releasing the obstruction of the positioning member 3 on the shaping fixture 2. At this time, the spring releases energy and automatically resets the shaping fixture 2 to the second position, reducing manual intervention and simplifying the operation process.

[0043] In this embodiment, two positioning elements 3 are provided, one on each side of the shaping fixture 2. The two positioning elements 3 allow the shaping device to be subjected to pressure from the symmetrically positioned elements 3 on both sides, resulting in a more stable bidirectional locking mechanism. Two support plates 302 are spaced apart on the same side of each positioning element 3, and a rotating shaft 303 is provided between the support plates 302. The positioning element 3 is fixed to the rotating shaft 303. The support plates 302 provide stable fulcrums, and the arrangement of the rotating shaft 303 facilitates the rotational arrangement of the positioning element 3.

[0044] like Figure 1 and Figure 2As shown, a torsion spring 304 is provided between the positioning component 3 and any support plate 302 on the same side. When the torsion spring 304 is in its natural state, the positioning component 3 is also in its natural state. The arrangement of the torsion spring 304 allows it to store energy during the movement of the shaping fixture 2 from the second station to the first station. When the shaping fixture 2 moves to the first station, the torsion spring 304 releases its energy, causing the positioning component 3 to automatically reset, as the positioning component 3 loses the external force. This makes operation more convenient and reduces human error. Furthermore, from another perspective, when the shaping fixture 2 needs to enter the first station, the construction worker only needs to slide the shaping fixture 2 by stepping on it, eliminating the need to bend over, making it more worker-friendly.

[0045] In addition, a crank handle 305 is connected to each rotating shaft 303, and the crank handle 305 is used to drive the rotating shaft 303 to rotate. By rotating the handle to drive the rotating shaft 303, it is convenient to operate the positioning component 3, reduce labor intensity, and is especially suitable for narrow construction environments.

[0046] In this embodiment, the positioning element 3 includes either a cam or a positioning rod. When the positioning element 3 is a cam, the cam's protrusion is the blocking end 301, and the cam's base circle is coaxially arranged with the rotation shaft 303. When the positioning element 3 is a positioning rod, one end of the positioning rod is fixed to the rotation shaft 303, and the other end of the positioning rod is the blocking end 301. The cam structure utilizes the protrusion to achieve precise blocking, while the positioning rod simplifies manufacturing, provides diverse options, and adapts to different cost and precision requirements. Of course, the positioning element 3 is not limited to the above shape; it can also be other applicable shapes. For example, the positioning element 3 can be a triangle, in which case the circumcenter of the triangle cannot be on the axis of the rotation shaft 303.

[0047] In this embodiment, the limiting mechanism includes a limiting rod 401, with both ends of the limiting rod 401 fixed to two support plates 302 on the same side. The limiting rod 401, fixed between the support plates 302, limits the stroke of the blocking end 301, has a simple and durable structure, and prevents the positioning component 3 from over-rotating and failing.

[0048] Finally, as Figure 7 and Figure 8 As shown, the limiting mechanism can also be a limiting groove 402, which is formed on one of its support plates 302. A portion of the blocking end 301 is located within the limiting groove 402. When the positioning member 3 is in its natural state, the side wall of the limiting groove 402 abuts against the top wall of the blocking end 301. The side wall of the limiting groove 402 blocks the blocking end 301 of the positioning member 3. The limiting groove 402 directly constrains the position of the blocking end 301, eliminating the need for additional parts. This integrated design reduces assembly complexity and improves maintenance convenience.

[0049] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
