Description

Technical Field

[0001] The utility model relates to the technical field of canal construction, in particular to a hoisting device for U-shaped lining plates used in small canal construction. Background Technique

[0002] Farmland irrigation often utilizes the water of rivers and lakes and introduces it into farmland through the "ditches" dug on the ground. Canals are artificially dug waterways, which are divided into main canals and branch canals. The main canals and branch canals are generally built with stone or cement.

[0003] During the construction of existing canals, U-shaped lining plates often need to be installed in the canals. When installing the U-shaped lining plates in the canals, a hoisting device is required to position the U-shaped lining plates, and then the hoisting machine is used to lift and transfer them into the canals. Most of the currently used hoisting devices are simple binding ropes or clamps, which clamp or bind from both sides of the U-shaped lining plates. However, after the U-shaped lining plates are placed in the canals, the binding ropes or clamps will be pressed, resulting in troublesome disassembly operations for the staff and thus affecting the hoisting efficiency. Therefore, we propose a hoisting device for U-shaped lining plates used in small canal construction. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hoisting device for U-shaped lining plates used in small canal construction, and solve the problems raised in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A hoisting device for U-shaped lining plates used in small canal construction, including a cross plate. The middle of the bottom of the cross plate is fixedly connected with a sleeve through a connecting column. Both ends of the sleeve are connected with movable rods. One side of the top of the sleeve penetrates through a bolt. A threaded hole adapted to the bolt is opened on the outer wall of the top of the movable rod. The bolt and the corresponding threaded hole are threadedly engaged. The outer end of the movable rod is connected with a tightening component.

[0006] The tightening component includes a fixed box, which is fixedly connected with the outer end of the movable rod. Both side walls of the fixed box are connected with threaded pipes. The openings of the threaded pipes are internally threadedly connected with screw rods. The outer ends of the screw rods are rotatably connected with tightening plates.

[0007] By adopting the above technical scheme, first, according to the length of the U-shaped lining plate, then loosen the bolt and pull the movable rod, so as to adjust the distance between the two tightening components on both sides to adapt to the length of the U-shaped lining plate. Then place the device in the inner cavity of the U-shaped lining plate, and then rotate the screw rods on both sides to drive the tightening plates to move outward, so that the tightening plates on both sides can be tightened against the inner wall of the U-shaped lining plate. Then use a hoisting machine to connect with the device for hoisting. After the hoisting is completed, directly rotate the screw rods in the reverse direction, so that rapid disassembly can be realized, the operation convenience is improved, and the hoisting efficiency is further improved.

[0008] As a preferred embodiment of the present utility model, a movable column penetrates through the top of the fixed box. A end plate is fixed to the tail end of the movable column. A first spring is sleeved on the outer wall of the movable column. Two ends of the first spring are respectively fixedly connected to the top of the end plate and the bottom of the fixed box. First wedge blocks are fixed to both side walls of the movable column and the first wedge blocks are located inside the fixed box. One end of the threaded pipe is movably inserted into the inner cavity of the fixed box and is fixedly connected to a second wedge block. A second spring is sleeved on the outer wall of the threaded pipe. Two ends of the second spring are respectively fixedly connected to the second wedge block and the inner wall of the fixed box.

[0009] By adopting the above technical solution, when lifting, it can drive the movable column to lift, so that it can drive the first wedge block to lift and then push the second wedge block to move outward, thereby pushing the threaded pipe and the screw rod to move outward, so as to improve the degree of tightness of the pressing plate against the U-shaped lining plate during lifting, and thus improve the stability of hoisting.

[0010] As a preferred embodiment of the present utility model, a limiting chute is opened at the bottom of the cross plate. Limiting sliders adapted to each other are inserted into both sides of the inner cavity of the limiting chute. The bottom of the limiting slider is fixedly connected to the top of the movable column.

[0011] By adopting the above technical solution, when adjusting the movement of the limiting components on both sides, the limiting sliders can slide in the limiting chute for limiting, improving the stability of adjustment.

[0012] As a preferred embodiment of the present utility model, a lifting ring is fixedly connected to the middle of the top of the cross plate.

[0013] By adopting the above technical solution, the setting of the lifting ring makes it convenient to connect with a crane.

[0014] As a preferred embodiment of the present utility model, a handle is fixed to the outer wall of the screw rod.

[0015] By adopting the above technical solution, the setting of the handle makes it convenient to hold the handle to rotate the screw rod.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] For a U-shaped lining plate hoisting device for small canal construction in the technical solution of the present application, by rotating the screw rods on both sides, the pressing plates can be driven to move, so that the pressing plates on both sides can directly press against the inner side walls of both sides of the U-shaped lining plate, so that the lifting tool will not be pressed after hoisting, making the disassembly convenient and improving the operation convenience and hoisting efficiency;

[0018] When lifted, it can drive the movable column to rise, so that the first wedge block can be driven to rise, and then the second wedge block will be pushed to move outward, thereby pushing the threaded pipe and the screw rod to move outward, so as to improve the tightening degree of the pressing plate against the U-shaped lining plate during lifting, and thus improve the stability of the lifting;

[0019] By loosening the bolts and then pulling the movable rod, the positions of the fixed boxes on both sides can be adjusted, so as to adapt to U-shaped lining plates of different lengths and improve the adaptability of the device. Brief Description of the Drawings

[0028] Please refer to Figures 1-3 , the present utility model provides a technical solution: a U-shaped lining plate lifting device for small canal construction, including a cross plate 1. The middle of the bottom of the cross plate 1 is fixedly connected with a sleeve 3 through a connecting column. Both ends of the sleeve 3 are connected with a movable rod 31. One side of the top of the sleeve 3 penetrates through a bolt 32. A threaded hole adapted to the bolt 32 is opened on the outer wall of the top of the movable rod 31. The bolt 32 and the corresponding threaded hole are threadedly engaged. The outer end of the movable rod 31 is connected with a tightening assembly;

[0029] The tightening assembly includes a fixed box 2, which is fixedly connected to the outer end of the movable rod 31. Threaded pipes 21 are connected to both side walls of the fixed box 2. A screw rod 22 is threadedly connected to the opening of the threaded pipe 21. The outer end of the screw rod 22 is rotatably connected to a tightening plate 23;

[0030] During actual use, first, according to the length of the U-shaped lining plate, then loosen the bolt 32 and pull the movable rod 31 to adjust the distance between the two tightening assemblies on both sides to adapt to the length of the U-shaped lining plate. Then place the device in the inner cavity of the U-shaped lining plate, and then rotate the screw rods 22 on both sides to drive the tightening plates 23 to move outward, so that the two tightening plates 23 can be tightened against the inner wall of the U-shaped lining plate. Then use a crane to connect with the device for hoisting. After the hoisting is completed, directly rotate the screw rods 22 in the reverse direction, which can achieve rapid disassembly, improve the operation convenience, and then improve the hoisting efficiency.

[0031] Furthermore, anti-slip patterns are provided on the outer wall of the tightening plate 23. The setting of the anti-slip patterns can increase the friction when tightening against the inner wall of the U-shaped lining plate, thereby improving the hoisting stability.

[0032] Even further, a lifting ring 11 is fixedly connected to the middle of the top of the cross plate 1. The setting of the lifting ring 11 makes it convenient to connect with a crane.

[0033] It is worth introducing that a handle 24 is fixed on the outer wall of the screw rod 22. The setting of the handle 24 makes it convenient to rotate the screw rod 22 by holding the handle 24.

[0034] As Figure 1 and 2 shown in FIGS. 3; a movable column 25 penetrates through the top of the fixed box 2. An end plate is fixed to the tail end of the movable column 25. A first spring 26 is sleeved on the outer wall of the movable column 25. The two ends of the first spring 26 are respectively fixedly connected to the top of the end plate and the bottom of the fixed box 2. First wedge-shaped blocks 27 are fixed to both side walls of the movable column 25 and the first wedge-shaped blocks 27 are placed inside the fixed box 2. One end of the threaded pipe 21 is movably inserted into the inner cavity of the fixed box 2 and is fixedly connected to a second wedge-shaped block 28. A second spring 29 is sleeved on the outer wall of the threaded pipe 21. The two ends of the second spring 29 are respectively fixedly connected to the second wedge-shaped block 28 and the inner wall of the fixed box 2;

[0035] When hoisting, it can drive the movable column 25 to lift, so that it can drive the first wedge-shaped block 27 to lift and then push the second wedge-shaped block 28 to move outward, thereby pushing the threaded pipe 21 and the screw rod 22 to move outward, which can improve the tightening degree of the tightening plate 23 against the U-shaped lining plate during hoisting, and thus improve the hoisting stability.

[0036] Further, a limiting sliding groove 12 is formed at the bottom of the transverse plate 1. Limiting sliding blocks 13 that fit are inserted into both sides of the inner cavity of the limiting sliding groove 12. The bottom of the limiting sliding block 13 is fixedly connected to the top of the movable column 25. Thus, when adjusting the movement of the limiting components on both sides, the limiting sliding block 13 can slide in the limiting sliding groove 12 for limiting, improving the stability of the adjustment.

[0037] The implementation principle of a U-shaped lining plate lifting device for small canal construction in this application is as follows: In actual use, first, according to the length of the U-shaped lining plate, then loosen the bolt 32 and pull the movable rod 31 to adjust the distance between the two tightening components on both sides to adapt to the length of the U-shaped lining plate. Then place the device inside the U-shaped lining plate cavity, and then rotate the screws 22 on both sides to drive the tightening plates 23 to move outward, so that the tightening plates 23 on both sides can be tightened against the inner wall of the U-shaped lining plate. Then use a crane to connect with the device for lifting. After the lifting is completed, directly rotate the screw 22 in the reverse direction to achieve quick disassembly, improving the operation convenience and further enhancing the lifting efficiency. And when lifting, it can drive the movable column 25 to rise, so that the first wedge block 27 can be driven to rise, which will then push the second wedge block 28 to move outward, thereby pushing the threaded pipe 21 and the screw 22 to move outward, so as to improve the tightening degree of the tightening plate 23 against the U-shaped lining plate during the lifting process, and thus improve the stability of the lifting.
