DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0024] Underground measurement control points are generally arranged on the roof of tunnels and goafs. Hanging lines usually requires ladders and other climbing equipment, which is inconvenient.

[0025] By installing a magnetic device on the top of the tunnel, the plumb line can be repeatedly disassembled without climbing during the subsequent replacement and adjustment of the plumb line, which simplifies the downhole measurement action and improves the efficiency of downhole measurement; however, due to the lack of guidance and positioning when only mutually attractive magnetic devices are set up, the operator cannot install the bottom magnetic device to the predetermined position at one time during the bottom operation; usually, the staff needs to adjust the position of the bottom magnetic device through a telescopic rod at the bottom, which causes inconvenience in operation, affects the positioning of the plumb line, and may even cause damage in severe cases.

[0026] In order to solve the above problems, refer to the attached Figure 1 -Attached Figure 4, a downhole magnetic adsorption wire hanging device, including an installation component for fixing the plumb line 200. The plumb line 200 is detachably connected to the installation component. After the plumb line 200 is damaged or different plumb lines 200 are replaced during different downhole measurement stages, different measurement requirements can be met. Specifically, the installation component includes a relatively fixed first positioning block 700 and a relatively movable second positioning block 300. There is magnetic attraction between the first positioning block 700 and the second positioning block 300, and the plumb line 200 is detachably connected to the second positioning block 300. During the installation process, the second positioning block 300 is fixed to the telescopic end of the telescopic rod, and the second positioning block 300 is pushed towards the first positioning block 700. After the second positioning block 300 and the first positioning block 700 are magnetically attracted, the telescopic end is disengaged from the second positioning block 300 to achieve the positioning installation of the second positioning block 300 and the plumb line 200. Here, the plumb line 200 is detachably connected to the second positioning block 300. During the process of replacing the plumb line 200, only the second positioning block 300 needs to be disassembled and adjusted.

[0027] A positioning sleeve 100 is sleeved outside the first positioning block 700, and a guiding component 600 is fixed outside the second positioning block 300. The guiding component 600 extends in a direction away from the first positioning block 700. A first positioning groove 710 is formed on the lower surface of the first positioning block 700, and a positioning protrusion 400 adapted to the first positioning groove 710 is fixed on the upper end of the second positioning block 300. The guiding component 600 can perform a primary guiding and positioning on the second positioning block 300. The guiding component 600 has a certain length and can effectively guide and position the second positioning block 300.

[0028] The second positioning block 300 can be secondarily guided and positioned through the positioning protrusion 400 and the first positioning groove 710. During the primary guiding and positioning process, the moving position of the second positioning block 300 can be restricted. During the secondary guiding and positioning process, the moving position of the second positioning block 300 can be further restricted, thereby ensuring that the second positioning block 300 is in an accurate position. Through the above method, the positioning after the magnetic adsorption and fixation of the second positioning block 300 can be simplified. The second positioning block 300 can be installed at an accurate position at one time, simplifying the subsequent operations of the staff and improving the efficiency of downhole measurement construction.

[0029] Here, the positioning protrusion 400 is made of a magnetic material and can be selected as a neodymium magnet. Here, the first positioning block 700 can be selected as a magnetic adsorption material adapted thereto.

[0030] Preferably, the first positioning groove 710 is set as an annular shape, and a chamfer 711 is provided at the outer edge of the first positioning groove 710. Through the setting of the chamfer 711, the positioning protrusion 400 can be further guided and positioned, so that the positioning protrusion 400 can enter the first positioning groove 710 at one time to achieve accurate positioning.

[0031] A second positioning groove 310 is formed on the lower surface of the second positioning block 300. The second positioning groove 310 can be adapted to the telescopic rod to realize the limit and fixation of the second positioning block 300. The second positioning block 300 and the telescopic rod can also be made of magnetic materials. By selecting materials with different magnetic force magnitudes, the installation and disassembly of the second positioning block 300 can be realized.

[0032] Specifically, the guiding component 600 is a plurality of elastic guiding and positioning rods. The plurality of guiding and positioning rods are arranged circumferentially around the second positioning block 300. When the plurality of elastic guiding and positioning rods enter the positioning sleeve 100, they can be in a state of being in contact with the inner wall of the positioning sleeve 100. The plurality of guiding and positioning rods are in a circumferentially distributed position to realize effective limit and fixation of the second positioning block 300.

[0033] Specifically, the guiding and positioning rod includes a mounting portion 610 fixed to the second positioning block 300, a pressing portion 630 in contact with the inner wall of the positioning sleeve 100, and an elastic portion 620 located between the mounting portion 610 and the pressing portion 630. The elastic portion 620 is in an inclined state. Through the above setting, the contact area between the guiding component 600 and the inner wall of the positioning sleeve 100 can be reduced, the resistance can be reduced, and it is convenient for the installation and positioning of the second positioning block 300.

[0034] A mounting plate 120 is fixed to the upper end of the positioning sleeve 100. The lower surface of the mounting plate 120 is fixed to the first positioning block 700. Mounting holes 121 are provided on the surface of the mounting plate 120. During the initial measurement process, the mounting plate 120 is installed at a predetermined position. During the subsequent measurement process, the construction personnel only need to remotely operate and position the second positioning block 300 through the telescopic rod.

[0035] A guiding sleeve 110 is fixed to the lower end of the positioning sleeve 100. The cross section of the guiding sleeve 110 is in a horn shape. Through the guiding sleeve 110, the second positioning block 300 and the guiding component 600 can be effectively positioned on the outside, further reducing the positioning difficulty of the operator.

[0036] The second positioning block 300 is a hollow ring shape. A crosshair 500 is provided on the inner wall of the second positioning block 300 for connecting the plumb line 200. The plumb line 200 can be fixed to the crosshair 500 by bolting. The second positioning block 300 is a hollow ring shape, which reduces the mass of the second positioning block 300, reduces the difficulty for the staff to lift it, and ensures the stability of lifting the second positioning block 300.

[0037] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
