Description

Technical Field

[0001] This application relates to the field of concrete pouring technology for anti-seepage walls, and in particular to a lifting device for a concrete pouring duct for anti-seepage walls. Background Technology

[0002] Currently, underwater concrete pouring operations in water conservancy projects, such as anti-seepage walls, cast-in-place piles, and bored piles, are all completed using underwater concrete pouring. Each section of the guide pipe needs to be connected in sequence and lowered into the trench to the designed depth. Then, concrete is injected into the guide pipe, and the concrete flows out from the bottom of the guide pipe to begin pouring. During the concrete pouring process, the guide pipe is raised and lowered multiple times to ensure the quality of the concrete pouring.

[0003] During construction, mobile cranes (such as truck cranes) are usually used to lift the conduits. Workers hang the wire rope on the crane hook, then tie the wire rope to the conduit and fix it with special rope clamps. After a conduit is lifted into place, the wire rope needs to be untied and retied, which is time-consuming and labor-intensive and affects the efficiency of conduit lifting. Summary of the Invention

[0004] To address the issue of time-consuming and labor-intensive pipe connection that affects hoisting efficiency, this application provides a lifting device for concrete pouring pipes in anti-seepage walls.

[0005] The technical solution of the lifting device for concrete pouring guide pipe of anti-seepage wall provided in this application is as follows:

[0006] A lifting device for a concrete pouring duct of an anti-seepage wall includes a base, a column vertically mounted on the base, a horizontal bar at the top of the column, a pulley on the horizontal bar, a winch mounted on the base, a traction rope wound around the roller of the winch, and the traction rope passing around the pulley and connected to a lifting device for clamping the duct.

[0007] The lifting device includes a lifting plate, a lifting rod, and a clamp. The lifting plate is connected to a traction rope, the lifting rod is rotatably connected to the bottom surface of the lifting plate, and steel wire ropes are connected to both ends of the lifting rod. The clamp is arc-shaped and has through holes at both ends for the steel wire ropes to pass through.

[0008] By adopting the above technical solution, the operator places the wire rope and clamp together on the threaded joint of the conduit. When the winch winds up the traction rope to start lifting, the wire rope will tighten with the clamp under tension, thus playing a self-locking role. When disassembling, the operator only needs to pull the wire rope to loosen it, which is convenient and quick, saves the time required for binding, and helps to improve the efficiency of conduit hoisting.

[0009] Optionally, both ends of the wire rope are connected to a lock buckle, and the boom is provided with a locking ring that engages with the lock buckle.

[0010] By adopting the above technical solutions, the lock and locking ring facilitate the connection and disassembly of the wire rope and the boom.

[0011] Optionally, both ends of the boom are fixed with reinforcing rods, and the ends of the two reinforcing rods away from the boom are connected to each other and rotatably connected to the boom plate.

[0012] By adopting the above technical solution, the boom and the two reinforcing rods form a triangular structure, which increases the overall strength and reduces the possibility of boom deformation.

[0013] Optionally, the column is provided with a positioning seat, and two positioning rods symmetrically distributed about the column are rotatably connected to the positioning seat via a rotating shaft. The ends of the two positioning rods facing the conduit are fixed with positioning clamps that match the outer diameter of the conduit by screws. The positioning seat is provided with a drive assembly for driving the two positioning clamps to rotate.

[0014] By adopting the above technical solution, after the conduit is lifted, the operator uses the drive assembly to drive the two positioning clamps to rotate and clamp the conduit, which plays a role in positioning and guiding the conduit.

[0015] Optionally, the drive assembly includes a first gear and a second gear. A positioning shaft is rotatably connected to the positioning seat. Two first gears are provided and are respectively connected to the positioning shaft and one of the rotating shafts, and the two first gears mesh with each other. Two second gears are provided and are respectively connected to the positioning shaft and the other rotating shaft. The two second gears are connected by a toothed belt. A pull rod is vertically provided on the positioning shaft, and a fixing unit for fixing the pull rod is provided on the positioning seat.

[0016] By adopting the above technical solution, the operator rotates the connecting rod to drive the positioning shaft to rotate, and the positioning shaft drives the first gear and the second gear on it to rotate. The first gear drives another first gear to rotate, and the second gear drives another second gear to rotate through the toothed belt, so that the two positioning rods drive the positioning hoop to move closer to each other, which is simple and convenient.

[0017] Optionally, the fixing unit includes a limiting rod and a limiting seat. The pull rod is hinged to the positioning shaft, and the hinge axis is perpendicular to the positioning shaft. The limiting rod is vertically arranged on the pull rod. The limiting seat is arranged on the positioning seat and located above the limiting rod. The limiting seat has a limiting groove corresponding to the limiting rod. The pull rod is connected to the positioning shaft through a first spring. Under the elastic force of the first spring, the pull rod drives the limiting rod to insert into the limiting groove.

[0018] By adopting the above technical solution, the pull rod, under the elastic force of the first spring, drives the limiting rod to remain inserted in the limiting groove, thus restricting the rotation of the positioning shaft. When it is necessary to rotate the positioning shaft, the operator can simply rotate the pull rod to move the limiting rod out of the limiting groove, which is convenient and quick.

[0019] Optionally, the column is provided with a limiting plate for the positioning shaft to pass through, and the limiting plate is located below the pull rod.

[0020] By adopting the above technical solution, when rotating the positioning shaft, the operator can make the pull rod press down against the limit plate, so that the pull rod is supported and the operator can apply force more easily.

[0021] Optionally, the base is rotatably connected to two guide plates via a first guide shaft. Each of the two guide plates has a guide groove for the conduit to pass through. The two guide plates are connected to the positioning shaft via a linkage assembly, and the rotation states of the guide plates and the positioning hoop are opposite.

[0022] By adopting the above technical solution, when the positioning ring of the first conduit abuts against the guide plate, the second conduit is lifted and connected to the first conduit. After the connection is completed, the operator drives the positioning shaft to rotate, the two positioning hoops wrap around the conduit, and the two guide plates rotate and separate from the conduit. This achieves guidance and positioning of the conduit throughout the lowering process, improves the positional accuracy of the conduit, and also reduces the shaking of the conduit.

[0023] Optionally, the linkage component includes a slider and connecting rods. The slider is slidably connected to the base. There are two connecting rods, both of which are hinged to the slider. The ends of the two connecting rods away from the slider are respectively hinged to two guide plates. The sidewall of the slider is provided with a rack. The lower end of the positioning shaft is rotatably connected to the base and is provided with a third gear that meshes with the rack.

[0024] By adopting the above technical solution, the rotation of the positioning shaft drives the third gear to rotate, the third gear drives the rack to move the slider, and the slider drives the two guide plates to rotate through the connecting rod, which is convenient and quick, and reduces the time required for the positioning hoop and guide plate to switch states.

[0025] Optionally, each of the two first guide shafts is rotatably connected to a scraper, and each of the two scrapers is provided with bristles on an opposite side. The base is rotatably connected to a second guide shaft corresponding to each of the two scrapers. Each of the two second guide shafts is provided with a lever, and the lever is connected to the base through a second spring. The two levers are respectively connected to the two scrapers through a swing arm.

[0026] By adopting the above technical solution, when the two guide plates open to each other, the guide plates push the lever to rotate, and the lever drives the scraper to rotate through the swing arm, so that the two scrapers move closer to each other. During the movement of the guide tube, the brush cleans the mud on the guide tube, which helps to reduce the subsequent guide tube cleaning work.

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

[0028] 1. Under tension, the wire rope will tighten with the clamp, thus playing a self-locking role. When disassembling, the operator only needs to pull the wire rope to loosen it, which is convenient and quick, saves the time required for binding, and helps to improve the efficiency of pipe hoisting.

[0029] 2. The alternating movement of the two positioning clamps and guide plates enables guidance and positioning of the guide tube throughout its lowering process, improving the positional accuracy of the guide tube and reducing its sway. The scraper rotates under the drive of the guide plate, enabling the cleaning of mud on the guide tube during its movement, which helps to reduce subsequent guide tube cleaning operations.

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses a lifting device for a concrete pouring duct in a seepage-proof wall. For example... Figure 1 The lifting device for the concrete pouring guide pipe 8 of the seepage prevention wall includes a base 1, a vertical column 11 on the base 1, a horizontal crossbar 12 at the top of the column 11, two pulleys 13 distributed along its length on the crossbar 12, a winch 14 installed on the base 1, a traction rope 141 wound on the roller of the winch 14, and the head of the traction rope 141 passes over the two pulleys 13 and is connected to a lifting device 2 for clamping the guide pipe 8.

[0038] like Figure 1 The lifting device 2 includes a lifting plate 21, a wire rope 24, and a clamp 23. The lifting plate 21 is connected to the traction rope 141. Two reinforcing rods 26 are rotatably connected to the bottom surface of the lifting plate 21, and the rotatable connection point of the two reinforcing rods 26 and the lifting plate 21 is the same point. A lifting rod 22 is fixed between the ends of the two reinforcing rods 26 away from the lifting plate 21. The lifting rod 22 and the two reinforcing rods 26 form a triangular structure. Both ends of the lifting rod 22 are provided with locking rings 25. The clamp 23 is arc-shaped and adapted to the outer periphery of the guide tube 8. Both ends of the clamp 23 are provided with through holes 231. The wire rope 24 passes through the two through holes 231 in sequence. Both ends of the wire rope 24 are connected with lock buckles 241. The two lock buckles 241 are respectively engaged with the two locking rings 25.

[0039] The wire rope 24 and the clamp 23 form a loop structure. The end of the conduit 8 is equipped with a threaded fitting 81. Near the fitting 81, coaxially distributed positioning rings 82 are fixed to control the position of the fitting 81. The diameters of both the fitting 81 and the positioning rings 82 are larger than the diameter of the conduit 8. When lifting the conduit 8, the operator places the wire rope 24 and clamp 23 onto the conduit 8, ensuring the clamp 23 abuts against the fitting 81, pulls the wire rope 24 to tighten it, and then starts the winch 14. The roller 14 winds up the traction rope 141 to lift the conduit 8. The wire rope 24 remains taut on the conduit 8 under the tension of the traction rope 141 and the weight of the conduit 8, forming a self-locking state. After the conduit 8 is in place, the operator lowers the lifting plate 21 to slack the wire rope 24. Then, the operator pulls the wire rope 24 to loosen it, which expands the inner diameter of the loop formed by the wire rope 24 and the clamp 23, thereby removing the clamp 23. This is convenient, quick, and does not require binding, saving time and effort and improving the hoisting efficiency of the conduit 8.

[0040] Since the wire rope 24 is inserted into the through hole 231, under the gravity of the guide tube 8, the wire rope 24 can automatically adjust the distance between the end of the clamp 23 and the rod 22 to ensure the balance of force.

[0041] like Figure 3 and Figure 4The column 11 is provided with a positioning seat 3 near the base 1. Two positioning rods 32 are symmetrically distributed about the column 11 and are rotatably connected to the positioning seat 3 via a rotating shaft 31. The two positioning rods 32 are fixed with positioning clamps 321 by screws at the ends facing the conduit 8. The inner diameter of the positioning clamps 321 is the same as the outer radius of the conduit 8. The positioning seat 3 is provided with a drive assembly 4 for driving the two positioning clamps 321 to rotate.

[0042] The drive assembly 4 includes two first gears 41 and two second gears 42. A positioning shaft 43 is rotatably connected to the positioning seat 3. The positioning shaft 43 is parallel to the rotating shaft 31. The two first gears 41 are coaxially fixed on the positioning shaft 43 and one of the rotating shafts 31, and the two first gears 41 mesh with each other. The two second gears 42 are coaxially fixed on the positioning shaft 43 and the other rotating shaft 31, and the two second gears 42 are connected by a toothed belt 44. The second gears 42 are located below the first gears 41. When the positioning shaft 43 rotates, the first gears 41 and the second gears 42 on the positioning shaft 43 rotate synchronously. Through the meshing transmission of the two first gears 41 and the meshing transmission of the second gears 42 and the toothed belt 44, the two rotating shafts 31 are driven to drive their corresponding positioning rods 32 to rotate synchronously in opposite directions, so that the two positioning clamps 321 move closer to each other or further away.

[0043] A pull rod 45 is hinged to the positioning shaft 43. The hinge axis of the pull rod 45 is perpendicular to the positioning shaft 43, allowing the pull rod 45 to rotate up and down. The pull rod 45 is located below the second gear 42. A limiting plate 431 is provided on the column 11 for the positioning shaft 43 to pass through. The limiting plate 431 is located below the pull rod 45 and is used to support the pull rod 45. When the pull rod 45 abuts against the limiting plate 431, the two are perpendicular to each other. The operator can rotate the pull rod 45 to drive the positioning shaft 43 to rotate.

[0044] The positioning seat 3 is provided with a fixing unit for fixing the pull rod 45. The fixing unit includes a limiting rod 451 that is vertically fixed to the end of the pull rod 45 away from the positioning shaft 43. The positioning seat 3 is provided with a limiting seat 47 corresponding to the limiting rod 451. The limiting seat 47 is located above the limiting rod 451 and has a limiting groove 471. The width of the limiting groove 471 is the same as the width of the limiting rod 451. A first spring 48 is connected between the pull rod 45 and the positioning shaft 43. Under the elastic force of the first spring 48, the pull rod 45 drives the limiting rod 451 to insert into the limiting groove 471, thereby restricting the rotation of the positioning shaft 43.

[0045] In the initial position, the pull rod 45 is offset from the limiting seat 47. Under the elastic force of the first spring 48, the pull rod 45 is tilted relative to the positioning shaft 43, and the two positioning clamps 321 are in a state of being far apart from each other. The operator rotates the pull rod 45 downward until it abuts against the limiting plate 431, so that the first spring 48 is stretched and produces elastic deformation. Then, the operator rotates the pull rod 45 horizontally to directly below the limiting seat 47. At this time, the two positioning clamps 321 are facing each other and their axes coincide. The operator gradually releases the pull rod 45, so that the pull rod 45 rotates upward under the elastic force of the first spring 48, driving the limiting rod 451 to insert into the limiting groove 471, restricting the rotation of the pull rod 45, thereby fixing the two positioning clamps 321.

[0046] like Figure 4 and Figure 5 The base 1 is rotatably connected to two guide plates 5 via a first guide shaft 51. Each guide plate 5 has a guide groove 52 for the conduit 8 to pass through. The guide groove 52 is arc-shaped and matches the outer contour of the conduit 8. The circle formed by the two guide grooves 52 is coaxially distributed with the circle formed by the two positioning clamps 321. The two guide plates 5 are connected to the positioning shaft 43 via a linkage assembly 6. The rotation directions of the guide plates 5 and the positioning clamps 321 are opposite. When the two positioning clamps 321 approach each other, the two guide plates 5 move away from each other.

[0047] The linkage component 6 includes a slider 61 slidably connected to the base 1. The slider 61 is located on the vertical line of the line connecting the two first guide shafts 51. Two connecting rods 62 are hinged to the end of the slider 61 facing the guide plate 5. The ends of the two connecting rods 62 away from the slider 61 are respectively hinged to the two guide plates 5. The end of the slider 61 away from the guide plate 5 passes through the column 11 and is connected to the side wall of the rack 63. The lower end of the positioning shaft 43 is rotatably connected to the base 1. The positioning shaft 43 and the rack 63 are distributed opposite to each other and are provided with a third gear 64 that meshes with the rack 63.

[0048] When the positioning shaft 43 rotates, it drives the third gear 64 to rotate, and the third gear 64 drives the rack 63 to move, causing the slider 61 to move forward and approach the guide plate 5. The two guide plates 5 move away from each other under the push of the connecting rod 62. When the positioning shaft 43 reverses, the slider 61 pulls the two connecting rods 62, causing the two guide plates 5 to rotate and move closer to each other.

[0049] Scrapers 7 are rotatably connected to both first guide shafts 51. Each scraper 7 has an arc-shaped groove on its opposite side. The inner diameter of the groove is larger than the radius of the guide tube 8. The groove wall is provided with bristles 71. A second guide shaft 72 corresponding to each of the two scrapers 7 is rotatably connected to the base 1. The second guide shaft 72 corresponds to the end of the scraper 7 away from the first guide post. Each of the two second guide shafts 72 is provided with a lever 73. One end of the lever 73 is located on the rotation trajectory of the guide plate 5 and is connected to the base 1 through a second spring 731. The other end is hinged to a swing rod 732. The end of the swing rod 732 away from the lever 73 is hinged to its corresponding scraper 7.

[0050] When the two guide plates 5 abut against each other, the two scrapers 7 open up to each other. When the two guide plates 5 rotate and separate, the guide plates 5 push the lever 73 to rotate, causing the second spring 731 to be compressed and produce elastic deformation. The swing rod 732 pushes the scraper 7 to rotate under the drive of the lever 73, causing the two scrapers 7 to rotate closer. When the two guide plates 5 rotate back and close, the lever 73 rotates under the elastic force of the second spring 731, causing the swing rod 732 to pull the scraper 7 to rotate and open.

[0051] The implementation principle of this application embodiment is as follows: When the conduit 8 is lowered, the two positioning clamps 321 open, and the two guide plates 5 abut against each other. The operator puts the wire rope 24 and clamp 23 on the pipe joint 81 of the conduit 8, starts the winch 14 to lift the conduit 8, so that the conduit 8 is located between the two positioning clamps 321, lowers the conduit 8, and places the pipe joint 81 at the lower end of the conduit 8 on the guide plate 5; the operator rotates the pull rod 45 and fixes it, driving the two positioning clamps 321 to rotate and hug the conduit 8. At the same time, the two guide plates 5 rotate and open, and the two scrapers 7 rotate and move closer under the drive of the guide plates 5, so that the bristles 71 abut against the outer wall of the conduit 8, and continues to lower the conduit 8.

[0052] When the positioning ring 82 of the conduit 8 moves to the position of the positioning clamp 321, the operator reverses the pull rod 45, causing the two positioning clamps 321 to rotate and open to facilitate the descent of the conduit 8. At the same time, the two guide plates 5 rotate to hold the conduit 8, and the two scrapers 7 rotate and open. When the positioning ring 82 of the conduit 8 moves and supports itself on the guide plate 5, the operator removes the wire rope 24 and clamp 23 to carry out the lifting operation of the next conduit 8.

[0053] After the second conduit 8 is lowered onto the first conduit 8, the operator uses a tool to rotate the conduit 8 so that the two conduits 8 are connected together. After the connection is made, the operator rotates the lever 45 to drive the two clamps 23 to hold the conduit 8 and causes the two guide plates 5 to rotate and open, allowing the conduit 8 to continue to be lowered. The above steps are repeated to guide and position the conduit 8 throughout the entire lowering process, thereby improving the positional accuracy of the conduit 8.

[0054] When lifting the conduit 8, the operator unscrews the screws to remove the positioning clamp 321, rotates the pull rod 45 to keep the two guide plates 5 open, and then lifts the conduit 8. During this process, the brush 71 scrapes off the mud attached to the conduit 8, saving the time required for subsequent cleaning of the conduit 8.

[0055] 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.
