Description

Technical Field

[0001] The utility model relates to the technical field of hydrogeological drilling, in particular to a pipe clamper for a hydrogeological hole wall. Background Art

[0002] In mud hydrogeological drilling operations, after the drilling construction is completed, it often takes a lot of time to lower the wellbore pipe. The conventional method is to cut two circular holes at the wellbore pipe welding point, insert the steel bars horizontally into the wellbore pipe, use wire rope to connect the steel bars to the power head, and then the power head will lift the wellbore pipe and drop it at the hole mouth for welding. Finally, the wire rope and steel bars are removed, and the cut circular holes are welded and sealed. The wellbore pipe is welded repeatedly in sequence. The operation is very cumbersome and takes a lot of time. The operation requires the operator to have rich practical experience. Often, because the wellbore pipe connection cannot be completely vertical, the wellbore pipe is offset after accumulation one by one, which causes the wellbore pipe to fail to reach the bottom of the well, resulting in a hydrological hole construction accident. Utility Model Content

[0003] The utility model aims to solve the shortcomings in the prior art and proposes a pipe clamp for the wall of a hydrogeological hole.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A pipe clamp for a hydrogeological borehole wall comprises a rectangular frame, the top of which is hinged with two symmetrically arranged first clamping plates, the first clamping plates are provided with a semicircular first clamping opening, a second clamping plate is rotatably mounted on the first clamping plate, and the second clamping plate is provided with a semicircular second clamping opening.

[0006] Preferably, a first handle is fixed on the first card plate, and a second handle is fixed on the second card plate.

[0007] Preferably, third handles are fixed to the four corners of the rectangular frame.

[0008] Preferably, a second sleeve is fixed to one end of the second clamping plate, a first sleeve is fixed to the first clamping plate, a same pin is rotatably sleeved between the second sleeve and the first sleeve, and the first clamping plate and the second clamping plate are rotatably connected via the first sleeve, the second sleeve and the pin.

[0009] Preferably, the diameter of the first bayonet is greater than the diameter of the second bayonet.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. In the utility model, the first handle is used to drive the first card plate to rotate, the second handle is used to drive the second card plate to rotate, and the second handle is used to drive the second card plate to rotate;

[0012] 2. In the utility model, the well wall pipe is clamped by the second clamping openings on the two second clamping plates. At this time, the lifting ring welded on the well wall pipe plays a role in preventing the well wall pipe from falling, thereby achieving the role of fixing the well wall pipe in disguise. When the well wall pipe is put on, it is only necessary to open the second clamping plate. The overall operation is automated, simple, convenient and fast, saving time, manpower and fuel compared with the commonly used methods, and achieving cost savings;

[0013] 3. In the utility model, by pulling out the pin from the first sleeve and the second sleeve, the second clamping plate can be easily replaced according to the diameter of the well wall pipe, so that the second clamping port on the second clamping plate matches the well wall pipe, which is very flexible to use.
