[0002] Overflow weir is a kind of hydraulic engineering structure, which is usually set up on hydraulic structures such as channels, reservoirs, dams, etc. When the water level exceeds a certain height, the water can overflow from the top of the weir to control the water level, regulate the flow, and discharge floods. There are many forms of overflow weirs, such as straight weirs, curved weirs, etc.

[0003] In the prior art, the devices used for overflow weir-related operations often have many limitations. For example, the traction device has poor adaptability and is difficult to cope with different operation requirements. It cannot flexibly match overflow weirs of different widths, resulting in insufficient versatility of the equipment, which is stretched when faced with complex and changeable actual operation scenarios; the guide rail is usually fixed and cannot be effectively adapted and assembled according to the length and multiple curvatures of the overflow weir, limiting its application in the construction of different overflow weirs; and in terms of leveling operations for overflow weirs of different widths, there is a lack of designs that can be adjusted efficiently and flexibly and meet actual needs, making it difficult to achieve high-quality leveling effects.

[0061] like Figure 21-25 As shown, the lifting assembly 4 includes a counterweight block 40 arranged on the steps on both sides of the overflow weir, a threaded barrel 42 is arranged in the counterweight block 40, a third screw rod 43 is arranged on the inner thread of the threaded barrel 42, a joint ball 44 is arranged on the top of the third screw rod 43, a plurality of anti-skid spikes 49 are arranged on the surface of the joint ball 44, a pair of lifting plates 45 are sandwiched on the top of the joint ball 44, and the bottoms of the two lifting plates 45 are provided with movable cavities 46, the joint ball 44 is located between the two movable cavities 46, and the two lifting plates 45 are connected by a pair of bolt groups 48, the top surface of the lifting plate 45 is fitted with the bottom surface of the assembled guide rail 2, the bottom of the counterweight block 40 is provided with rubber anti-skid patterns 41, and the third screw rod 43 is also provided with a hexagonal nut 47, and the hexagonal nut 47 is located below the joint ball 44;

[0062] In actual use, firstly, the adjustable traction device 1 needs to be towed to the required location for construction work by a trailer. After arriving at the location, the overall direction and angle are adjusted to ensure that it is completely flush with the working surface. Next, the four lifting support feet 11 are started to lift the counterweight installation body 10, so that the several universal wheels 12 at the bottom are off the ground to ensure the stability of the device. Then, the operator adjusts the distance between the two traction devices according to the width of the overflow weir. The specific operation is to control the first motor 110 to rotate forward, and the first motor 110 drives the bidirectional lead screw 19 to rotate, thereby prompting the driving blocks 111 on both sides to move inward synchronously. When the spacing between the two driving blocks 111 is the same as the width of the overflow weir, the operation of the first motor 110 can be stopped. Then, by controlling the two first telescopic cylinders 17, the "C"-shaped mounting plate 15 is lowered so that the bottom surface of the "C"-shaped mounting plate 15 contacts the ground.

[0063] Next, according to the overall length of the overflow weir, select the corresponding number of assembly components 20 to assemble the assembled guide rail 2: first select the assembly component 20 with the fixing part 23, insert the connecting groove 210 on its connecting plate 21 into the first screw rod 116, and then fit the connecting plate 21 tightly to the ground, then put the gasket 240 on the first screw rod 116, and then screw in the horn nut 241 to tighten it, and finally use two expansion bolts 25 to pass through the fixing parts 23 respectively and drive them into the ground, so that the installation of the first assembly component 20 is completed, and then install another assembly component 20 with a fixing part 23 according to the above steps, and install it behind the previous assembly component 20, Then, select several assembly components 20 without fixing parts 23 in order, place their connecting plates 21 between the two limit plates 22 of the previous assembly component 20, align the connecting groove 1 210 with the connecting hole 220, and then insert the second screw rod 24. After inserting the second screw rod 24, adjust the angle according to the curvature of the overflow weir so that it fits perfectly on both sides of the overflow weir, and then put gaskets 240 on both ends of the second screw rod 24, and then tighten it with the horn nut 241 to fix it. According to the above steps, the operation is carried out in sequence until the assembly guide rail 2 is assembled. Finally, the "L"-shaped fixing piece is connected to the tail of the assembly guide rail 2, and then it is fixed with the expansion bolt 25.

[0064] Then, it is necessary to set several lifting assemblies 4 at equal intervals at the bottom of the assembled guide rail 2. First, place the counterweight 40 at the bottom of the assembled guide rail 2. Then, the operator uses a wrench to tighten the hexagonal nut 47 to move the third screw 43 upward until the lifting plate 45 fits the bottom surface of the assembled guide rail 2. Then, the two lifting plates 45 can be adjusted according to the inclination angle of the assembled guide rail 2 to fit perfectly with its bottom surface. Finally, tighten the two bolt groups 49 to make the two lifting plates 45 hold the joint ball 44 tightly. With the cooperation of several anti-slip spikes 49, the two lifting plates 45 are fixed, thereby realizing the lifting force on the assembled guide rail 2.

[0065] Next, the sliding membrane device 3 is adjusted: first, according to the width of the overflow weir, a corresponding number of second smoothing pieces 38 are installed on the two mounting rods 341 respectively, and the second slots 382 of the second smoothing pieces 38 are aligned with the mounting slots 31 and inserted, and they are installed on the mounting rods 341 in sequence. Between two adjacent second smoothing pieces 38, the second limiting blocks 380 are used to cooperate with the second limiting slots 381 for fixing and limiting. After all the second smoothing pieces 38 on both sides are installed, by starting the second motor 36 for forward rotation, the second motor 36 drives the transmission gear 37 to rotate clockwise, thereby driving the racks 353 on both sides to move inward synchronously, thereby driving the load-bearing blocks 350 on both sides to move inward synchronously, until the load-bearing blocks 350 on both sides are respectively flush with the assembled guide rails 2 on both sides, the operation of the second motor 36 can be stopped, and then the second telescopic cylinders 356 on both sides are started to drive the pressing plates 357 to move inward, so as to press and fix the second smoothing pieces 38;

[0066] Finally, the traction ropes 1130 on the two traction devices 113 are passed through the guide assembly 114 in the manner shown in Figure 8, and then respectively fixed to the hooks 355 on the front of the two load-bearing blocks 350. Then the synovial device 3 is lifted and placed on the assembled guide rail 2. Finally, the two traction devices are started to slowly pull the synovial device 3 upward. As the synovial device 3 moves upward, the second smoothing piece 38 at its bottom can smooth the concrete on the overflow weir. In addition, the two hooks 355 on the back of the first synovial device 3 can be connected to another synovial device 3 through steel ropes. In actual use, the previous synovial device 3 can perform preliminary smoothing operations, while the second synovial device 3 can perform further smoothing and improvement.
