Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a lifting device for concrete pouring ducts in underground continuous walls. Background Technology

[0002] Underwater concrete pouring is the final and most crucial step in the construction of diaphragm walls. Any abnormalities during the pouring process will inevitably affect the overall quality of the wall. Diaphragm wall concrete pouring employs the vertical guide pipe method. To ensure the quality of the underwater concrete pouring, a guide pipe is used for each unit section. After pouring is completed, the guide pipe needs to be removed.

[0003] Most lifting devices are currently used by hoists or cranes. Although they can lift the pouring pipe, they can only be used in a large area and cannot be used in a narrow area. Therefore, they have certain limitations in actual use and will affect the lifting of the pouring pipe. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting device for concrete pouring pipes in underground continuous walls, so as to solve at least one of the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for a concrete pouring guide pipe for a continuous underground wall, comprising a base plate, with support seats fixedly connected to all four sides of the bottom of the base plate, a connecting frame fixedly connected to the top of the base plate, sliding grooves on both sides of the inner wall of the connecting frame, a U-shaped plate on the top of the connecting frame, a first lead screw rotatably connected to one side of the inner cavity of the connecting frame via bearings, a drive motor fixedly connected to the top of the U-shaped plate, a second lead screw mounted on the output end of the drive motor via a coupling, a fixing frame mounted in the middle of the first and second lead screws, two square plates fixedly connected to the left side of the fixing frame, rotating rods rotatably connected to one side of each of the two square plates via bearings, and electric telescopic rods fixedly connected to the other side of each of the two rotating rods.

[0006] Preferably, the top of the first lead screw is fixedly connected to the top of the connecting frame with a first pulley, the outer ring of the second lead screw is fitted with a second pulley, and the second pulley is movably connected to the outer ring of the first pulley with a belt.

[0007] Preferably, a handle is fixedly connected to one side of each of the two rotating rods, and a hand guard is fixedly connected to one side of each of the two handles. Both hand guards are made of soft cotton material.

[0008] Preferably, the top of the fixing frame has two circular holes that are adapted to the first lead screw and the second lead screw respectively, and both sides of the fixing frame are fixedly connected with sliders that are adapted to the sliding groove.

[0009] Preferably, each of the two electric telescopic rods has a clamping ring fixedly connected to its output end, a mounting groove is provided on the top of each of the two clamping rings, a mounting block is provided in the inner cavity of each of the two mounting grooves, a protective ring is fixedly connected to the bottom of each of the two mounting blocks, and both protective rings are made of rubber.

[0010] Preferably, the tops of the two protective rings and the clamping ring are respectively provided with a first threaded groove and a second threaded groove, and the inner cavities of the first threaded groove and the second threaded groove are threadedly connected with fastening bolts.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, the output ends of two electric telescopic rods drive two clamping rings to move to both sides of the guide tube, adjusting the distance between the two clamping rings to ensure tight clamping and fixation with both sides of the guide tube. The protective rings, made of rubber, prevent the clamping rings from making hard contact with the guide tube and causing injury. This device can provide protective clamping for casting guide tubes of different diameters, preventing them from wobbling and falling during lifting. The fastening bolts are then locked in the corresponding first and second threaded grooves. Turning the knob counterclockwise releases the protective rings from the clamping rings, allowing the two protective rings to be removed. This facilitates the disassembly and replacement of protective rings that have been in use for an extended period.

[0013] 2. In this utility model, the output end of the drive motor drives the second lead screw and the second pulley to rotate. When rotating, the first pulley and the first lead screw are driven by the belt. When the first lead screw and the second lead screw rotate synchronously, the fixed frame is driven to slide up and down in the slide groove through the two circular holes and the slider. When sliding, the two clamping rings and the pouring guide between them move up and down together. Moreover, this device can be used in a relatively narrow area, so that the operator can automatically lift the pouring guide. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figure 1-4 The illustrated underground continuous wall concrete pouring guide pipe lifting device includes a base plate 1. Support seats 2 are fixedly connected to the bottom four sides of the base plate 1. A connecting frame 3 is fixedly connected to the top of the base plate 1. Sliding grooves 4 are opened on both sides of the inner wall of the connecting frame 3. A U-shaped plate 5 is provided on the top of the connecting frame 3. A first lead screw 6 is rotatably connected to one side of the inner cavity of the connecting frame 3 through a bearing. A drive motor 7 is fixedly connected to the top of the U-shaped plate 5. A second lead screw 8 is fitted to the output end of the drive motor 7 through a coupling. A fixing frame 12 is fitted in the middle of the first lead screw 6 and the second lead screw 8. Two square plates 13 are fixedly connected to the left side of the fixing frame 12. A rotating rod 14 is rotatably connected to one side of each of the two square plates 13 through a bearing. An electric telescopic rod 17 is fixedly connected to the other side of each of the two rotating rods 14.

[0021] Furthermore, the top of the first lead screw 6 is fixedly connected to the top of the connecting frame 3, and the outer ring of the second lead screw 8 is fitted with a second pulley 10. The second pulley 10 and the outer ring of the first pulley 9 are movably connected by a belt 11. The top of the fixed frame 12 is provided with two circular holes 25 that are respectively adapted to the first lead screw 6 and the second lead screw 8. The two sides of the fixed frame 12 are fixedly connected with sliders 26 that are adapted to the slide groove 4. The output end of the drive motor 7 drives the second lead screw 8 and the second pulley 10 to rotate. When rotating, the first pulley 9 and the first lead screw 6 are driven by the belt 11. When the first lead screw 6 and the second lead screw 8 rotate synchronously, the fixed frame 12 is driven to slide up and down in the slide groove 4 through the two circular holes 25 via the sliders 26. When sliding, the two clamping rings 18 and the pouring guide between them move up and down together. Moreover, this device can be used in a relatively narrow area, which makes it convenient for operators to automatically lift the pouring guide.

[0022] Furthermore, a handle 15 is fixedly connected to one side of each of the two rotating rods 14, and a hand guard 16 is fixedly connected to one side of each of the two handles 15. Both hand guards 16 are made of soft cotton material. By rotating the handle 15, the two rotating rods 14 can be rotated via the bearings. When rotating, the two clamping rings 18 are rotated slightly to finely adjust the angle of the pouring pipe. At the same time, the hand guards 16, made of soft cotton material, can prevent wear and tear on the operator's hands and provide comfort, thereby enabling the operator to use the device in a variety of ways.

[0023] Furthermore, each of the output ends of the two electric telescopic rods 17 is fixedly connected to a clamping ring 18. The top of each clamping ring 18 is provided with a mounting groove 19, and the inner cavity of each mounting groove 19 is provided with a mounting block 20. The bottom of each mounting block 20 is fixedly connected to a protective ring 21. Both protective rings 21 are made of rubber. The output ends of the two electric telescopic rods 17 drive the two clamping rings 18 to move to both sides of the guide tube, adjusting the distance between the two clamping rings 18 to fit tightly against both sides of the guide tube for clamping and fixing. At the same time, the protective rings 21 made of rubber can prevent the clamping rings 18 from making hard contact with the guide tube and causing pinching damage. Thus, this device can perform protective clamping, fixing and lifting work on casting guide tubes of different diameters.

[0024] Furthermore, the tops of the two protective rings 21 and the clamping ring 18 are respectively provided with a first threaded groove 22 and a second threaded groove 23. The inner cavities of the first threaded groove 22 and the second threaded groove 23 are threadedly connected with fastening bolts 24. By turning the fastening bolts 24 counterclockwise in the corresponding first threaded groove 22 and second threaded groove 23, the fixing of the protective rings 21 and the clamping ring 18 is released, and then the two protective rings 21 can be taken out, which makes it convenient for operators to disassemble and replace the protective rings 21 that have been used for too long.

[0025] In practical implementation, the casting conduit is first placed between two clamping rings 18. Then, the output ends of two electric telescopic rods 17 drive the two clamping rings 18 to move to both sides of the conduit, adjusting the distance between the two clamping rings 18 until they are tightly clamped and fixed to the sides of the conduit. Simultaneously, the protective rings 21, made of rubber, prevent the clamping rings 18 from making rigid contact with the conduit, thus preventing injury. Therefore, this device can provide protective clamping for casting conduits of different diameters, preventing them from swaying and falling during lifting. After the image is fixed, the output end of the drive motor 7 drives the second lead screw 8 and the second pulley 10 to rotate. When rotating, the first pulley 9 and the first lead screw 6 are driven by the belt 11. When the first lead screw 6 and the second lead screw 8 rotate synchronously, the fixing frame 12 is driven to slide up and down in the slide groove 4 through the two circular holes 25 via the slider 26. When sliding, the two clamping rings 18 and the pouring guide between them move up and down together. Moreover, this device can be used in a relatively narrow area, which makes it convenient for operators to automatically lift the pouring guide.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
