Abstract
Description
Technical Field
[0001] The invention discloses a steel wire free suspension protection structure for vertical shaft directional connection measurement, which is used for steel wire free suspension protection and belongs to the technical field of vertical shaft directional connection measurement. Background Art
[0002] Shaft directional measurement is a method used in tunnel construction and underground mining tunnel excavation. It is primarily used to connect surface and underground horizontal and vertical control to a common coordinate system. Shaft directional measurement consists of two main parts: horizontal measurement (often called shaft directional measurement or shaft orientation) and vertical measurement (also called shaft height transfer).
[0003] During tunnel construction, vertical shafts are often used to increase the working surface, allowing tunnel construction to be carried out from multiple sides and improving the progress of tunnel construction. In order to ensure the correct penetration of the tunnel during construction, the coordinates, azimuth and elevation of the ground control points need to be transmitted to the underground through the construction shaft. We usually call this work shaft directional connection measurement. The basic principle is to hang two steel wires in the shaft, one end of the steel wire is fixed above the wellhead, and the other end is tied with a weight and freely suspended at the bottom of the well. The two steel wires are used to transmit the ground coordinates and azimuth to the underground connection point, so that the ground coordinate system is consistent with the underground coordinate system; at the same time, a steel ruler is used to transmit the ground elevation to the underground point elevation to ensure the consistency of the ground and underground elevation systems.
[0004] In the prior art, one end of the steel wire is fixed above the wellhead, and the other end is tied with a weight and freely suspended to the bottom of the well through a guide device. However, the following technical problems still exist when the steel wire is tied with a weight and freely suspended to the bottom of the well:
[0005] 1. The steel wire at the wellhead is easily affected by wind and sways, which can easily cause the weight to collide with the well wall, which will not only damage the well wall structure, but also cause the steel wire to bend and affect the measurement results;
[0006] 2. The lowering position of the steel wire cannot be adjusted, and the need to install the guide device a second time or directly lower the steel wire will directly affect the measurement results. Utility Model Content
[0007] The purpose of the utility model is to provide a free-hanging protective structure for steel wire used for directional connection measurement in a vertical shaft, so as to solve the problem that the steel wire at a section of the wellhead in the prior art is easily affected by wind and swings, thereby easily causing the heavy hammer to collide with the well wall, which not only damages the well wall structure, but also may cause the steel wire to bend and affect the measurement results.
[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0009] A steel wire free-hanging protective structure for shaft directional connection measurement, comprising a support frame, and a buffering protective structure provided on the support frame for guiding and force buffering the steel wire;
[0010] The buffer protection structure includes an elastic guide member A and an elastic guide member B arranged on the support frame. The elastic guide member A and the elastic guide member B are arranged on the support frame along the free suspension direction of the steel wire.
[0011] Furthermore, the elastic guide member A and the elastic guide member B include a square frame, an elastic reset member disposed on one opposite side of the square frame, a rotating shaft disposed on the elastic reset member, and a roller disposed on the rotating shaft, wherein a cavity for allowing the steel wire to pass through is formed between the two rollers;
[0012] When the elastic guide member A and the elastic guide member B are arranged on the support frame, the rollers on the elastic guide member A and the elastic guide member B are arranged horizontally and perpendicularly, and when the elastic reset member on the elastic guide member A or the elastic guide member B is fully compressed under force, the roller under force on the elastic guide member A or the elastic guide member B is located on the intersection line with the roller on the elastic guide member B or the elastic guide member A.
[0013] Furthermore, the elastic reset member includes a telescopic rod arranged on the square frame, a spring sleeved on the telescopic rod, and a rotating shaft connected to the telescopic rod and the spring.
[0014] Furthermore, the buffer protection structure also includes a guide wheel arranged on the support frame, and the elastic guide member A and the elastic guide member B are arranged under the guide wheel.
[0015] Furthermore, the support frame includes a base, a rotating rod and an arc-shaped inverted U-shaped slide rotatably arranged on the base, a movable groove is arranged on the top of the arc-shaped inverted U-shaped slide, a rotating part is arranged on the rotating rod and cooperates with the arc-shaped inverted U-shaped slide for sliding, a screw is arranged on the rotating part and cooperates with the movable groove for sliding, a nut is arranged on the screw, and a horizontal telescopic part is also arranged on the rotating rod, and the horizontal telescopic part is provided with a mounting part for installing a guide wheel, an elastic guide part A and an elastic guide part B.
[0016] Furthermore, a T-shaped slot is provided on the base, and a rotating head rotatably connected to the T-shaped slot is provided on the rotating rod.
[0017] Furthermore, the horizontal telescopic member is an electric telescopic rod or a hydraulic telescopic mechanism.
[0018] Furthermore, the mounting member includes a mounting plate connected to the horizontal telescopic member, a guide wheel connecting member arranged on one side of the top of the mounting plate, and a guide member connecting plate arranged on the mounting plate below the guide wheel connecting member.
[0019] Furthermore, the bottom surface of the base is provided with cone teeth and / or the base is provided with mounting holes.
[0020] Compared with the prior art, the advantages of the present invention are:
[0021] First, the present invention provides elastic guides A and B on the support frame to guide and buffer the steel wire, preventing the steel wire from bending under wind force and the risk of the weight colliding with the well wall. This not only ensures the verticality of the freely suspended steel wire, thereby improving measurement accuracy, but also effectively avoids the risk of the weight colliding with the well wall and damaging the well wall structure.
[0022] 2. The rollers in the elastic guide member A and the elastic guide member B in the present invention are arranged correspondingly, and the rollers in the elastic guide member A and the rollers in the elastic guide member B are arranged perpendicularly to each other, which not only ensures that the steel wire can be freely suspended to the bottom of the well in the cavity area formed by the rollers on the elastic guide member A and the elastic guide member B, but also when the steel wire is affected by wind, any elastic reset member is stressed and can provide a buffering force, absorb and disperse these forces, reduce the swing of the steel wire, and thus protect the steel wire from bending. When the elastic reset member on the elastic guide member A or the elastic guide member B is fully compressed, the stressed roller on the elastic guide member A or the elastic guide member B is located on the intersection line with the roller on the elastic guide member B or the elastic guide member A, so as to prevent the steel wire from moving under force, causing the steel wire to detach from the roller, thereby affecting the problem of free suspension, that is, to limit the steel wire from deviating too much when affected by external force;
[0023] 3. The elastic reset member in the utility model is mounted on the telescopic rod through a spring, which can automatically reset the steel wire after being subjected to an external force, thereby maintaining the stability of the guide member and ensuring that the steel wire is always on the correct guide path;
[0024] Fourth, the utility model is provided with a guide wheel to provide precise guidance for the steel wire, while avoiding the use of elastic guide members A and B as a guide mechanism, which may cause the steel wire with a heavy hammer to apply pressure to the roller during guidance, resulting in poor buffering effect and affecting the guiding stability;
[0025] 5. The support frame in the present invention rotates with the base through a rotating rod, and the rotating member is driven by the rotating rod to rotate with the arc-shaped inverted U-shaped slide and the movable groove, so as to adjust the angle of the guide wheel, the elastic guide member A and the elastic guide member B, and fix them by the nut and the screw. At the same time, the horizontal distance of the guide wheel, the elastic guide member A and the elastic guide member B is adjusted by the horizontal telescopic rod, so as to adjust the lowering position of the steel wire, thereby avoiding the problem of secondary installation of the guide device or directly lowering the steel wire, which will directly affect the measurement results.
[0026] 6. The present invention has high flexibility and is convenient for adjusting the angles of the guide wheel, the elastic guide member A and the elastic guide member B by cooperating with the rotating head on the rotating rod and the T-slot. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Example 1
[0043] In order to solve the problem that the steel wire at the wellhead section of the existing technology is easily affected by wind and swings, which makes it easy for the hammer to collide with the well wall, which will not only damage the well wall structure, but also cause the steel wire to bend and affect the measurement results. Figure 1-6As shown, a free-hanging steel wire protection structure for shaft directional communication measurement is provided, comprising a support frame 1 and a buffer protection structure 2 mounted on the support frame 1 to guide and buffer the steel wire. The buffer protection structure 2 includes elastic guides A3 and B4 mounted on the support frame 1. The elastic guides A3 and B4 are arranged on the support frame 1 along the free-hanging direction of the steel wire. The elastic guides A3 and B4 form a set, and one or more sets may be provided on the support frame 1.
[0044] In practice, the support frame is directly placed in a designated position and fixed by its own gravity or by other means. After fixation, one end of the steel wire is fixed to a point on the wellhead, and the steel wire with the weight is then matched with the elastic guide member A3 and the elastic guide member B4, so that the elastic guide member A3 and the elastic guide member B4 guide the steel wire and buffer the force so that the steel wire is freely suspended to the bottom of the well. This embodiment can guide and buffer the steel wire by arranging the elastic guide members A and B on the support frame, preventing the steel wire from bending under the action of wind and the risk of the weight colliding with the well wall. This not only ensures the verticality of the freely suspended steel wire, thereby improving the measurement accuracy, but also effectively avoids the risk of the weight colliding with the well wall and damaging the well wall structure.
[0045] Example 2
[0046] On the basis of Example 1, the elastic guide member A3 and the elastic guide member B4 include a square frame 5, an elastic reset member 6 arranged on an opposite side of the square frame 5, a rotating shaft 7 arranged on the elastic reset member 6, a roller 8 arranged on the rotating shaft 7, and a cavity 9 for accommodating the steel wire to pass through is formed between the two rollers 8; when the elastic guide member A3 and the elastic guide member B4 are arranged on the support frame 1, the rollers 8 on the elastic guide member A3 and the elastic guide member B4 are arranged horizontally and perpendicularly, and when the elastic reset member 6 on the elastic guide member A3 or the elastic guide member B4 is fully compressed under force, the stressed roller 8 on the elastic guide member A3 or the elastic guide B4 is located on the intersection line with the roller on the elastic guide member B4 or the elastic guide A3.
[0047] In practice, one end of the steel wire is fixed to a point on the wellhead, and the other end of the steel wire is then passed through the cavity of the elastic guide A3 and the elastic guide B4 and then fixed with a heavy hammer. After fixation, the steel wire cooperates with the roller 8 in the elastic guide A3 at the upper end to be freely suspended to the bottom of the well. In the process of freely hanging to the bottom of the well, when the steel wire is affected by wind force, the steel wire is guided by the roller 8 on the elastic guide A3 and the elastic guide B4, and the force is buffered by the elastic reset member. After freely hanging to the bottom of the well, the steel wire can be measured without being removed from the elastic guide A3 and the elastic guide B4 according to needs. Or when the steel wire needs to be removed from the elastic guide A3 and the elastic guide B4, the steel wire can be removed from the elastic guide A3 and the elastic guide B4 by removing one end from the wellhead, and then the steel wire at one end of the wellhead is fixed to the specified position. Of course, an opening can also be provided on any side where the roller 8 is not provided to facilitate cooperation with or removal from the elastic guide A3 and the elastic guide B4. In this embodiment, the rollers in the elastic guide member A and the elastic guide member B are arranged correspondingly, and the rollers in the elastic guide member A and the rollers in the elastic guide member B are arranged perpendicularly to each other, which not only ensures that the steel wire can be freely suspended to the bottom of the well in the cavity area formed by the rollers on the elastic guide member A and the elastic guide member B, but also when the steel wire is affected by wind, any elastic reset member is stressed and can provide buffering force, absorb and disperse these forces, reduce the swing of the steel wire, and thus protect the steel wire from bending. When the elastic reset member on the elastic guide member A or the elastic guide member B is fully compressed, the stressed roller on the elastic guide member A or the elastic guide member B is located on the intersection line with the roller on the elastic guide member B or the elastic guide member A, so as to prevent the steel wire from moving under force, causing the steel wire to detach from the roller, thereby affecting the problem of free suspension, that is, to limit the steel wire from deviating too much when affected by external force.
[0048] Example 3
[0049] Based on Example 2, the elastic return member 6 includes a telescopic rod 10 mounted on the square frame 5, a spring 11 sleeved on the telescopic rod 10, and a rotating shaft 7 connected to the telescopic rod 10 and the spring 11. The elastic return member is sleeved on the telescopic rod via the spring and automatically resets itself when the steel wire is subjected to an external force, maintaining the stability of the guide member and ensuring that the steel wire always stays on the correct guide path. Of course, in practice, other structures are possible.
[0050] Example 4
[0051] Based on Example 3, the buffer protection structure 2 further includes a guide wheel 12 provided on the support frame 1, and the elastic guide members A3 and B4 are provided below the guide wheel 12. The purpose of providing the guide wheel is to provide precise guidance for the steel wire, while avoiding the use of the elastic guide members A and B as a guide mechanism, which may cause the steel wire with the weight to apply pressure to the roller during guidance, resulting in poor buffering effect and affecting the guiding stability.
[0052] Example 5
[0053] On the basis of Example 4, the support frame 1 includes a base 13, a rotating rod 14 and an arc-shaped inverted U-shaped slide 15 rotatably arranged on the base 13, a movable groove 16 is arranged on the top of the arc-shaped inverted U-shaped slide 15, a rotating part 17 that slides with the arc-shaped inverted U-shaped slide 15 is arranged on the rotating rod 14, a screw 18 that slides with the movable groove 16 is arranged on the rotating part 17, a nut 27 is arranged on the screw 18, and a horizontal telescopic part 19 is also provided on the rotating rod 14, and a mounting part 20 for mounting the guide wheel 12, the elastic guide part A3 and the elastic guide part B4 is provided on the horizontal telescopic part 19. Bevel teeth are provided on the bottom surface of the base 13 and / or mounting holes 26 are provided on the base (the mounting holes 26 allow the cone rod to pass through the cone and enter the ground) for fixation. The horizontal telescopic part 19 is an electric telescopic rod or a hydraulic telescopic mechanism, and can also be a manually adjustable telescopic rod, such as by providing a penetrable mounting hole to cooperate with a bolt and a nut. As Figure 6 As shown, the mounting member 20 includes a mounting plate 23 connected to the horizontal telescopic member 19, a guide wheel connecting member 24 arranged on the top side of the mounting plate 23, and a guide member connecting plate 25 arranged on the mounting plate 23 below the guide wheel connecting member 24. Of course, in practice, the mounting member can also adopt other structures.
[0054] In practice, after the base is fixed in a designated position by means of bevel teeth provided on the base itself or on the bottom surface of the base 13 and / or mounting holes 26 provided on the base, the angles of the guide wheels, elastic guide members A and B are adjusted by rotating the base with the rotating rod, and the rotating member is driven by the rotating rod to rotate with the arc-shaped inverted U-shaped slide and the movable groove. The guide wheels, elastic guide members A and B are fixed by means of a nut and a screw. At the same time, the horizontal distance between the guide wheels, elastic guide members A and B is adjusted by a horizontal telescopic rod to facilitate adjustment of the lowering position of the steel wire, thereby avoiding the need for secondary installation of the guide device or the problem of directly lowering the steel wire, which would directly affect the measurement results.

[0056] Based on Example 5, the base 13 is provided with a T-slot 21, and the rotating rod 14 is provided with a rotating head 22 rotatably connected to the T-slot 21. The cooperation between the rotating head on the rotating rod and the T-slot provides high flexibility and facilitates angle adjustment of the guide wheel, elastic guide member A, and elastic guide member B. Of course, in practice, other structures are not excluded.
