Water conservancy construction plugging cover dismounting device

Abstract

The invention relates to a water conservancy construction plugging cover dismounting device and discloses a device used for fixing a plugging cover through multipoint balanced clamping and then dismounting the plugging cover through rotation. The water conservancy construction plugging cover dismounting device is characterized in that a bearing is arranged at the middle position of a lower supporting plate, a sponge cushion is arranged in the inner ring of the bearing, rubber is arranged on the surface of the sponge cushion, a sliding groove is formed in the lower supporting plate and locatedin the upper surface of the lower supporting plate, and the sliding groove is wavy and is composed of four groups of wave crests and wave troughs; two adjusting rods are symmetrically arranged on thelower supporting plate and penetrate the lower supporting plate, and one end of each adjusting rod is wedgy and is located on the upper surface of the lower supporting plate; a guide supporting plateis arranged in the inner ring of the lower supporting plate through a ceramic ring and comes into contact with the end face of the bearing; and the guide supporting plate is of an annular structure, the diameter of the inner ring of the guide supporting plate is larger than that of the inner ring of the bearing, a connecting ring is arranged on the outer edge of the guide supporting plate, and four guide grooves are formed in the connecting ring at equal intervals.

Description

Problems solved by technology

[0002] At present, in the process of water conservancy construction, in order to dredge the pipeline in the later stage, a three-way structure will be used at the position where it is easy to deposit, and one of the ports will be blocked by a plugging cover, so that it can be disassembled later to clean the foreign matter in the pipe , to dredge the pipeline, the existing plugging caps are all threaded and screwed, and wrapped with a raw material tape, for sealing and sealing, so it is extremely troublesome, time-consuming and laborious to disassemble, and the existing disassembly is done through the pipe wrench The clamping teeth clamp both sides of the plugging cap, and the two clamping points are symmetrical, but the force acting on the plugging cap is unbalanced, and the pipe wrench will deflect during disassembly, and during the rotation, the pipe wrench will If it slips, you need to readjust the clamping force of the pipe wrench. If the force is too tight during rotation, indentations will be formed on the surface of the plugging cover, and when clamping at both ends of the plugging cover, the blocked port will be deformed and affect the rotation. Disassembly, and because the plugging caps are not all round, the pipe wrench is prone to clamping is not firm or no place to clamp, affecting the disassembly of the capping plate, or it can no longer be used after disassembly, some existing ones are easy to disassemble The plugging caps of different types only require less force when dismantling, but they are not suitable for high water pressure plugging, and disassembly also needs to be carried out by pipe wrench, and some plugging caps are rotated and disassembled through a T-shaped structure. , the force arm of the crossbar rotation is limited, and the rotation force when it is transmitted to the plugging cover becomes smaller, and the force required for disassembly is invisible, which is time-consuming and labor-intensive.
