Description

Technical Field

[0001] This invention relates to the field of underground utility tunnel engineering technology, and in particular to a construction auxiliary device and method for a waterstop strip in an underground integrated utility tunnel. Background Technology

[0002] Underground utility tunnels refer to structures and ancillary facilities built underground in cities to house urban engineering pipelines. They are crucial infrastructure for ensuring urban operation, and preventing leakage during construction is paramount to the overall quality of the tunnel's construction. Waterstops in underground utility tunnels are designed to prevent groundwater from seeping into the tunnel, protecting its structural safety and durability. Waterstops are typically installed at structural joints, especially in concrete joints, expansion joints, and construction joints. Their function is to prevent water infiltration through waterproofing and sealing.

[0003] During the construction of waterstops in underground utility tunnels, some auxiliary devices are needed to ensure the accuracy, quality, and safety of the construction. When connecting multiple waterstops, welding equipment is required to weld the joints. This necessitates the use of clamps to hold and align the joints of the two waterstops.

[0004] In the existing technology, traditional clamps can only clamp and bring two waterstops close together, and can only facilitate welding on one side of the waterstop. They are not convenient for welding the upper and lower joints of the waterstop, resulting in low welding efficiency of the waterstop and failing to meet the usage requirements. To address this, we propose a construction auxiliary device and method for waterstops in underground integrated pipe corridors to solve the above problems. Summary of the Invention

[0005] The purpose of this application is to provide a construction auxiliary device and method for waterstops in underground integrated pipe gallery, so as to solve the problem mentioned in the background art that the traditional clamps can only clamp and bring two waterstops close together, and can only conveniently weld one side of the waterstop, but are not convenient to weld the upper and lower joints of the waterstop, resulting in low welding efficiency of the waterstop and failure to meet the use requirements.

[0006] To achieve the above objectives, this application provides the following technical solution: a construction auxiliary device for waterstops in underground integrated pipe galleries, comprising a base plate and two waterstop bodies, the construction auxiliary device further comprising: Two U-shaped frames are provided, and both U-shaped frames are slidably connected to the top of the base plate; The flipping assembly consists of two components: a C-shaped outer plate, a C-shaped inner plate, a C-shaped gear ring, a support plate, a second motor, a gear, two first electric push rods, and two clamping plates. The top and bottom of the C-shaped outer plate are fixedly installed on the top and bottom inner walls of the corresponding U-shaped frame, respectively. The C-shaped inner plate is rotatably connected to the inside of the C-shaped outer plate. The C-shaped gear ring is fixedly installed on one side of the C-shaped outer plate. The bottom end of the support plate is fixedly installed on the bottom inner wall of the corresponding U-shaped frame. The second motor is fixedly installed on the top of the support plate. The output shaft of the second motor passes through the support plate and is fixedly installed on the gear. The gear meshes with the C-shaped gear ring. The two first electric push rods are fixedly installed on the top and bottom inner walls of the C-shaped inner plate, respectively. The sides of the two clamping plates that are far apart from each other are fixedly installed on the output shafts of the two first electric push rods, and the sides of the two clamping plates that are close to each other are in contact with the top and bottom of the corresponding waterstop body, respectively. Two limiting components are provided, which are set on the rear inner wall of the corresponding C-shaped inner plate and cooperate with the rear side of the corresponding waterstop body. A drive assembly is disposed on the rear side of the base plate and engages with the rear sides of the two U-shaped frames respectively.

[0007] Using the above structure, by inserting the two waterstop bodies into the interiors of two C-shaped inner plates at their respective close ends, and then activating four first electric push rods, the two first electric push rods on the same side can drive the two clamping plates to move closer together and clamp and fix the corresponding waterstop bodies. After the two waterstop bodies are fixed, the drive assembly drives the two U-shaped frames and the two waterstop bodies to move closer together, at which point the close ends of the two waterstop bodies will be joined. Then, the joining ends of the two waterstop bodies can be welded by welding equipment. After the upper surface of the joining ends of the two waterstop bodies is welded, the two second motors can be activated to drive the two gears to rotate. When the two gears rotate, they can drive the two C-shaped gear rings, the two C-shaped inner plates, the four first electric push rods, the four clamping plates, and the two waterstop bodies to rotate, thereby enabling the two waterstop bodies to be flipped over. This facilitates the welding processing of the other side of the two waterstop bodies. In this way, the connection ends of the two waterstop bodies can be quickly welded, greatly improving the welding efficiency.

[0008] Preferably, a first sliding rod is fixedly installed at the bottom of each of the two U-shaped frames, and a first sliding groove is opened at the top of the base plate, with the bottom ends of the two first sliding rods slidably connected in the first sliding groove.

[0009] Furthermore, the sliding limit cooperation between the first slide rod and the first slide groove enables stable sliding limit and sliding support for the U-shaped frame.

[0010] Preferably, two second slide rods are fixedly installed on the bottom inner wall of the U-shaped frame, and two second slide grooves are opened on the outer side of the C-shaped inner plate, with the top of the second slide rods slidably connected in the corresponding second slide groove.

[0011] Furthermore, the sliding limit cooperation between the second slide rod and the second slide groove enables stable rotational limiting and rotational support of the C-shaped inner plate.

[0012] Preferably, the limiting component includes a baffle and a second electric push rod. The second electric push rod is fixedly installed on the rear inner wall of the corresponding C-shaped inner plate. The rear side of the baffle is fixedly installed on the output shaft of the second electric push rod. The front side of the baffle is in contact with the rear side of the waterstop body.

[0013] Furthermore, by activating the second electric push rod, the baffle can be moved back and forth, thereby adjusting the blocking position of the baffle according to the width of the waterstop body. This ensures that the waterstop body is positioned in the middle of the two clamps and guarantees precise docking between the two waterstop bodies, ensuring a good welding effect.

[0014] Preferably, the drive assembly includes a housing, a first motor, a dual-axis lead screw, and two moving rods. The housing is fixedly installed on the rear side of the base plate, the first motor is fixedly installed on the right side of the housing, the left end of the dual-axis lead screw is rotatably connected to the left inner wall of the housing, the right end of the dual-axis lead screw is fixedly installed on the output shaft of the first motor, the bottom ends of the two moving rods penetrate the top of the housing and extend into the interior of the housing, the two moving rods are threaded onto the dual-axis lead screw, and the front ends of the moving rods are fixedly installed on the rear side of the corresponding U-shaped frame.

[0015] Furthermore, starting the first motor can drive the dual-axis lead screw to rotate. When the dual-axis lead screw rotates, through the threaded connection between the dual-axis lead screw and the two moving rods, the two moving rods can be driven to move closer or further apart. When the two moving rods move closer together, they can drive the two U-shaped frames and the two waterstop bodies fixed inside them to move closer together, thereby facilitating precise docking between the two waterstop bodies.

[0016] Preferably, a bearing is fixedly sleeved on the dual-axis lead screw, and the bottom of the bearing is fixedly installed on the bottom inner wall of the housing.

[0017] Furthermore, by incorporating bearings, the dual-axis lead screw can be stably supported during rotation.

[0018] Preferably, two sliding holes are provided on the top inner wall of the box, and the top end of the moving rod passes through the corresponding sliding hole and is slidably connected to the inner wall of the sliding hole.

[0019] Furthermore, by creating sliding holes, the moving rod can be stably supported and its movement limited.

[0020] Preferably, fixing plates are fixedly installed on the top inner wall and bottom inner wall of the U-shaped frame, and the ends of the two fixing plates that are close to each other are respectively fixedly installed on the top and bottom of the C-shaped outer plate.

[0021] Furthermore, by setting a fixing plate, the C-shaped outer panel and the U-shaped frame can be stably installed and fixed.

[0022] This invention also proposes a method for using a construction auxiliary device for underground integrated pipe gallery waterstops, comprising the following steps: S1: First, connect the first motor, the second motor, the first electric push rod, and the second electric push rod to the external power supply. S2: Then, by inserting the two waterstop bodies into the interior of the two C-shaped inner plates at their respective close ends, and then activating the four first electric push rods, the two first electric push rods on the same side can drive the two clamping plates to move closer to each other and achieve clamping and fixing of the corresponding waterstop bodies. S3: Then, the drive component drives the two U-shaped frames and the two waterstop bodies to move closer to each other. At this time, the two waterstop bodies will be joined at one end, and then the welding equipment can be used to weld the top gap of the joined end of the two waterstop bodies. S4: In addition, by starting two second motors, two gears can be driven to rotate. When the two gears rotate, they can drive two C-shaped toothed rings, two C-shaped inner plates, four first electric push rods, four clamping plates and two waterstop bodies to rotate, thereby enabling the two waterstop bodies to be flipped over. This makes it easier to weld the other side of the two waterstop bodies. S5: Finally, by activating the second electric push rod, the baffle can be moved back and forth, thereby adjusting the blocking position of the baffle according to the width of the waterstop body, so that the waterstop body is located in the middle of the two clamps, and can ensure that the two waterstop bodies are precisely connected to ensure the welding effect.

[0023] The beneficial effects of this invention are: 1. By activating two first electric push rods on the same side, two clamping plates can be moved closer together to clamp and fix the corresponding waterstop body. After the two waterstop bodies are fixed, the drive assembly drives two U-shaped frames and two waterstop bodies to move closer together. At this time, the two waterstop bodies will be joined at one end. Then, the welding equipment can be used to weld the joined ends of the two waterstop bodies. After the upper surface of the joined ends of the two waterstop bodies is welded, the two second motors can be activated to drive two gears to rotate. When the two gears rotate, they can drive two C-shaped toothed rings, two C-shaped inner plates, four first electric push rods, four clamping plates and two waterstop bodies to rotate, thereby enabling the two waterstop bodies to be flipped over. This makes it easier to weld the other side of the two waterstop bodies. In this way, the connection end of the two waterstop bodies can be quickly welded, which greatly improves the welding efficiency. 2. By activating the second electric push rod, the baffle can be moved back and forth, thereby adjusting the blocking position of the baffle according to the width of the waterstop body. This ensures that the waterstop body is located in the middle of the two clamps and guarantees precise docking between the two waterstop bodies, thus ensuring the welding effect. 3. By starting the first motor, the double-axis lead screw can be driven to rotate. When the double-axis lead screw rotates, through the threaded connection between the double-axis lead screw and the two moving rods, the two moving rods can be driven to move closer or further apart. When the two moving rods move closer together, they can drive the two U-shaped frames and the two waterstop bodies fixed inside them to move closer together, thereby facilitating precise docking between the two waterstop bodies. This invention achieves stable fixation of two waterstop bodies through a simple structure. At the same time, it can flip the two waterstop bodies after clamping, which facilitates the complete welding of the joint ends of the two waterstop bodies. This greatly improves the processing efficiency and effect of the two waterstop bodies and has strong practicality. Attached Figure Description

The bottom end of the support plate 17 is fixedly installed on the corresponding U-shaped frame 8. On the bottom inner wall, the second motor 18 is fixedly installed at the top of the support plate 17. The output shaft of the second motor 18 passes through the support plate 17 and is fixedly installed on the gear 19. The gear 19 meshes with the C-shaped gear ring 16. The two first electric push rods 21 are respectively fixedly installed on the top inner wall and the top inner wall of the C-shaped inner plate 13. The two clamping plates 22 are respectively fixedly installed on the output shafts of the two first electric push rods 21 on the side that is far away from each other. The two clamping plates 22 are respectively in contact with the top and bottom of the corresponding waterstop body 23 on the side that is close to each other. Two limiting components are provided, which are set on the rear inner wall of the corresponding C-shaped inner plate 13 and cooperate with the rear side of the corresponding waterstop body 23. The drive assembly is located on the rear side of the base plate 1 and cooperates with the rear sides of the two U-shaped frames 8 respectively.

[0028] Using the above structure, by inserting the two waterstop bodies 23 into the interiors of the two C-shaped inner plates 13 at their respective close ends, and then activating the four first electric push rods 21, the two first electric push rods 21 on the same side can drive the two clamping plates 22 to move closer together and clamp and fix the corresponding waterstop bodies 23. After the two waterstop bodies 23 are fixed, the drive assembly drives the two U-shaped frames 8 and the two waterstop bodies 23 to move closer together, at which point the close ends of the two waterstop bodies 23 will be joined together. Then, the joining ends of the two waterstop bodies 23 can be welded using welding equipment. Next, after the upper surfaces of the two waterstop bodies 23 are welded together, the two second motors 18 can be started to drive the two gears 19 to rotate. When the two gears 19 rotate, they can drive the two C-shaped toothed rings 16, the two C-shaped inner plates 13, the four first electric push rods 21, the four clamping plates 22 and the two waterstop bodies 23 to rotate, thereby enabling the two waterstop bodies 23 to be flipped over. This makes it easier to weld the other side of the two waterstop bodies 23. In this way, the connection end of the two waterstop bodies 23 can be quickly welded, which greatly improves the welding efficiency.

[0029] In this embodiment, the bottom of each of the two U-shaped frames 8 is fixedly installed with a first sliding rod 9, and the top of the base plate 1 is provided with a first sliding groove 10.

[0031] In this embodiment, the limiting component includes a baffle 20 and a second electric push rod 24. The second electric push rod 24 is fixedly installed on the rear inner wall of the corresponding C-shaped inner plate 13. The rear side of the baffle 20 is fixedly installed on the output shaft of the second electric push rod 24. The front side of the baffle 20 is in contact with the rear side of the waterstop body 23. By activating the second electric push rod 24, the baffle 20 can be moved back and forth, thereby adjusting the blocking position of the baffle 20 according to the width of the waterstop body 23. This allows the waterstop body 23 to be located in the middle of the two clamping plates 22, and ensures precise docking between the two waterstop bodies 23, guaranteeing the welding effect.

[0032] In this embodiment, the driving assembly includes a housing 2, a first motor 3, a dual-axis lead screw 4, and two moving rods 6. The housing 2 is fixedly installed on the rear side of the base plate 1, the first motor 3 is fixedly installed on the right side of the housing 2, the left end of the dual-axis lead screw 4 is rotatably connected to the left inner wall of the housing 2, and the right end of the dual-axis lead screw 4 is fixedly installed on the output shaft of the first motor 3. The bottom ends of the two moving rods 6 penetrate the top of the housing 2 and extend into the interior of the housing 2. The two moving rods 6 are threaded onto the dual-axis lead screw 4, and the front ends of the moving rods 6 are fixedly installed on the rear side of the corresponding U-shaped frame 8. By starting the first motor 3, the dual-axis lead screw 4 can be driven to rotate. When the dual-axis lead screw 4 rotates, through the threaded connection between the dual-axis lead screw 4 and the two moving rods 6, the two moving rods 6 can be driven to move closer or further apart. When the two moving rods 6 move closer together, they can drive the two U-shaped frames 8 and the two waterstop bodies 23 fixed inside them to move closer together, thereby facilitating precise docking between the two waterstop bodies 23.

[0033] In this embodiment, a bearing 5 is fixedly sleeved on the dual-axis lead screw 4, and the bottom of the bearing 5 is fixedly installed on the bottom inner wall of the housing 2. By setting the bearing 5, the dual-axis lead screw 4 can be stably rotated and supported.

[0035] In this embodiment, fixing plates 11 are fixedly installed on the top inner wall and bottom inner wall of the U-shaped frame 8. The two fixing plates 11 are fixedly installed on the top and bottom of the C-shaped outer plate 12 respectively at their close ends. By setting the fixing plates 11, the C-shaped outer plate 12 and the U-shaped frame 8 can be stably installed and fixed.

[0036] This invention also proposes a method for using a construction auxiliary device for underground integrated pipe gallery waterstops, comprising the following steps: S1: First, connect the first motor 3, the second motor 18, the first electric push rod 21, and the second electric push rod 24 to the external power supply; S2: Then, by inserting the two waterstop bodies 23 close to each other into the interior of the two C-shaped inner plates 13 respectively, and then activating the four first electric push rods 21, the two first electric push rods 21 located on the same side can drive the two clamping plates 22 to approach each other and achieve clamping and fixing of the corresponding waterstop bodies 23. S3: Then, the two U-shaped frames 8 and the two waterstop bodies 23 are driven to move closer to each other by the drive component. At this time, the two waterstop bodies 23 will be connected at one end, and then the top gap of the two waterstop bodies 23 can be welded by the welding equipment. S4: In addition, by starting the two second motors 18, the two gears 19 can be driven to rotate. When the two gears 19 rotate, they can drive the two C-shaped toothed rings 16, the two C-shaped inner plates 13, the four first electric push rods 21, the four clamping plates 22 and the two waterstop bodies 23 to rotate, thereby enabling the two waterstop bodies 23 to be flipped over, which makes it easier to weld the other side of the two waterstop bodies 23. S5: Finally, by activating the second electric push rod 24, the baffle 20 can be moved back and forth, thereby adjusting the blocking position of the baffle 20 according to the width of the waterstop body 23, so that the waterstop body 23 is located in the middle of the two clamps 22, and can ensure that the two waterstop bodies 23 are precisely connected to ensure the welding effect.

[0037] It should be noted that the specific models of the first motor 3, the second motor 18, the first electric push rod 21, and the second electric push rod 24 used shall be selected by those skilled in the art. Furthermore, the first motor 3, the second motor 18, the first electric push rod 21, and the second electric push rod 24 mentioned above are all existing technologies, and this solution will not elaborate on them.

[0038] Working principle: In use, firstly, connect the first motor 3, the second motor 18, the first electric push rod 21, and the second electric push rod 24 to an external power source. Then, insert the two waterstop bodies 23 into the interiors of the two C-shaped inner plates 13 at their respective close ends. Next, activate the four first electric push rods 21. At this time, the two first electric push rods 21 on the same side can drive the two clamping plates 22 to move closer together and clamp and fix the corresponding waterstop bodies 23. After the two waterstop bodies 23 are fixed, the drive assembly drives the two... The U-shaped frame 8 and the two waterstop main bodies 23 approach each other, at which point the two waterstop main bodies 23 will be joined together. Then, the joining ends of the two waterstop main bodies 23 can be welded using welding equipment. After the upper surfaces of the joining ends of the two waterstop main bodies 23 are welded, the two second motors 18 can be started to drive the two gears 19 to rotate. When the two gears 19 rotate, they can drive the two C-shaped toothed rings 16, the two C-shaped inner plates 13, the four first electric push rods 21, the four clamping plates 22, and the two waterstop main bodies. The body 23 rotates, allowing the two waterstop bodies 23 to be flipped over. This facilitates welding on the other side of the two waterstop bodies 23, enabling rapid welding of the connecting ends of the two waterstop bodies 23 and greatly improving welding efficiency. The second electric push rod 24 moves the baffle 20 back and forth, adjusting its position according to the width of the waterstop body 23. This ensures the waterstop body 23 is positioned between the two clamping plates 22, guaranteeing precise docking and welding effectiveness. The first motor 3 rotates the double-axis lead screw 4. When the lead screw 4 rotates, the threaded connection between it and the two moving rods 6 moves the two moving rods closer or further apart. When the two moving rods 6 move closer, they bring the two U-shaped frames 8 and the two waterstop bodies 23 fixed inside them closer together, facilitating precise docking of the two waterstop bodies 23.

9. A method for using a construction auxiliary device for waterstops in underground integrated pipe corridors, characterized in that, Includes the following steps: S1: First, connect the first motor (3), the second motor (18), the first electric push rod (21), and the second electric push rod (24) to the external power supply; S2: Then, by inserting the two waterstop bodies (23) close to each other into the interior of the two C-shaped inner plates (13), and then activating the four first electric push rods (21), the two first electric push rods (21) located on the same side can drive the two clamping plates (22) to approach each other and achieve clamping and fixing of the corresponding waterstop bodies (23); S3: Then, the two U-shaped frames (8) and the two waterstop bodies (23) are driven to approach each other by the drive component. At this time, the two waterstop bodies (23) will be connected at one end. Then, the top gap of the two waterstop bodies (23) can be welded by the welding equipment. S4: In addition, by starting two second motors (18), two gears (19) can be driven to rotate. When the two gears (19) rotate, they can drive two C-shaped toothed rings (16), two C-shaped inner plates (13), four first electric push rods (21), four clamping plates (22) and two waterstop bodies (23) to rotate, thereby enabling the two waterstop bodies (23) to be flipped over. At this time, it is convenient to weld the other side of the two waterstop bodies (23). S5: By activating the second electric push rod (24), the baffle (20) can be moved back and forth, thereby adjusting the blocking position of the baffle (20) according to the width of the waterstop body (23), so that the waterstop body (23) is located in the middle of the two clamps (22), and can ensure that the two waterstop bodies (23) are precisely connected to ensure the welding effect.
