Description

Technical Field

[0001] The utility model belongs to the technical field of downhole pipes for dewatering, and particularly relates to a safe and convenient downhole pipe device for dewatering. Background Art

[0002] At present, in the construction of drainage well pipes, manual methods are usually adopted to fix the well pipes to the iron plate, and the steel wire rope is used to connect the iron plate and fix it to the steel pipes on both sides of the wellhead. The well pipe is lowered into the well by winding the steel wire rope and manual traction. For each section of the well pipe, workers need to connect the two well pipes with bamboo strips and iron wires, and carry out the well pipe installation construction in turn. This construction method requires at least 5 people to complete the construction, and there are many safety hazards during the construction process. Since the steel wire ropes on both sides need to be manually pulled and braked, there is a risk of people losing their hands. The people fixing the well pipe are close to the wellhead, and the land around the wellhead is mostly muddy, so there is a risk of people falling into the well. Utility Model Content

By providing a down-pipe mechanism, the installation of the upper pipe and the lower pipe of the device is completed mechanically, which can avoid safety accidents of personnel, improve work efficiency, reduce personnel deployment, and solve the problem that there are many safety hazards in the construction process. Since the steel wire ropes on both sides need to be manually pulled and braked, there is a risk of personnel losing their hands. The personnel fixing the well pipe are close to the wellhead, and the land around the wellhead is mostly muddy, so there is a risk of personnel falling into the well.

[0004] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0005] The utility model is a safe and convenient down-pipe device for a water-lowering well, comprising a connecting ring and a connecting frame, wherein a down-pipe mechanism, a lifting mechanism, an adjusting mechanism and a buffer mechanism are arranged on the connecting ring, and the down-pipe mechanism comprises a supporting component and a connecting component;

[0006] The supporting assembly includes a connecting frame fixedly connected to a connecting ring, the inner wall of the connecting frame is fixedly connected to four first connecting plates, one end of the four first connecting plates away from the connecting frame is fixedly connected to a connecting disc, a first sliding rod passes through the connecting disc, the connecting disc is slidably connected to the first sliding rod, and the bottom end of the first sliding rod is fixedly connected to a fixed connecting plate, four grooves are arranged inside the connecting frame, the inner walls of the four grooves are fixedly connected to second rotating shafts, the four second rotating shafts are rotatably connected to support rods, the top ends of several of the support rods are rotatably connected to wheels, and the top surface of the connecting frame is fixedly connected to a hanging ring.

[0012] The utility model has the following beneficial effects:

[0013] By providing a lower pipe mechanism, the crane can be connected to the lifting ring before operation. When the connecting frame is put into the interior of the upper pipe from the top of the upper pipe, when the four wheels contact the inner wall of the upper pipe, the inner wall of the upper pipe squeezes the four support rods. Under the action of the second rotating shaft, the bottom ends of the support rods move away from each other. At this time, the first spring is stretched. After the connecting frame passes through the upper pipe and comes out from the bottom of the upper pipe, the first spring is reset, and the top ends of the support rods move away from each other, so that the support rods contact the bottom surface of the upper pipe, so that the four support rods support the upper pipe. After the connecting frame repeats the operation and slides into the interior of the lower pipe, the upper pipe and the lower pipe are spliced ​​together to complete the installation. The connecting ring cooperates with the first rotating shaft to avoid twisting and deformation of the first spring when stretched or contracted, thereby improving safety during use. At this time, the connecting frame can be pulled upward so that the connecting frame can slide out from the top of the upper pipe. The installation of the upper pipe and the lower pipe of the device is completed mechanically, which can avoid safety accidents for personnel, improve work efficiency, and reduce personnel allocation.

[0014] By providing an adjustment mechanism, the slot and the pin cooperate with each other, so that the height of the slider can be adjusted, thereby the height of the positioning plate can be adjusted. When the top end of the support rod supports the upper pipe, the bottom end of the support rod rotates upward and contacts with the bottom surface of the rubber baffle, and then the support rod stops rotating, so that the rubber baffle can position the rotation of the support rod. The second spring and the second sliding rod cooperate with each other to buffer the force generated when the support rod contacts the rubber baffle, thereby avoiding damage to the device due to excessive force.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
