[0006] The technical solution to achieve the purpose of the utility model is: a pipeline lowering control device in pipe well operation, including a soil wall, a fixed bracket is attached to the soil wall, two rope fixing assemblies are installed on the top of the fixed bracket, ropes are slidably sleeved on the two rope fixing assemblies, a pipe well is wrapped around the cylindrical outer wall of the rope, a placement hole is opened on the soil wall, the pipe well is placed in the placement hole, telescopic columns are fixedly connected to the two rope fixing assemblies, the other ends of the two telescopic columns are fixedly connected to extrusion blocks, the two extrusion blocks are attached with ropes, and reset springs are sleeved on the two telescopic columns, and the two ends of the reset springs are respectively fixedly connected to the telescopic columns and the extrusion blocks.

[0007] Compared with the prior art, the present invention has the following significant advantages:

[0008] When the utility model is used, the frame of the device is placed above the pipe well, the pipe well is lowered from the middle of the device, the rope is fixed to the bottom of the lowest pipe well, the two ends of the rope are respectively wound on the two rope fixing components of the fixing bracket, the rope is wound two or three times, and each time a section of the pipe well is added, a section of the rope is lowered, and the extrusion block on the telescopic column squeezes the rope through the setting of the reset spring, so as to achieve accurate control of the lowering height and speed, and at the same time, the speed of the rope lowering to the pipe well can be delayed, so as to realize the lowering of the pipe well, thereby achieving economic savings and reducing labor costs;

[0009] The invention solves the problems that in the existing dewatering well construction, there is no sand pipe well below after the hole is completed, and the pipe well is lowered by manually pulling the rope, and the lowering speed is controlled manually, which makes it difficult to control the speed, the lowered pipe well is not easy to be too heavy, and it is difficult to accurately control the lowering elevation.
