Description
Technical Field
[0001] The utility model belongs to the technical field of mine shaft measurement, and relates to a hook device used for metal mine shaft connection measurement. Background Art
[0002] The establishment of the first-level control points of underground tunnels in metal mines is generally completed through shaft orientation. One of the key links of shaft orientation is contact measurement, which is to transfer the coordinates of the projection points and the relative height difference to the basic control points of the required middle tunnel. The traditional method is to build a working platform in each middle section of the orientation, and to stabilize the steel wire, check the smoothness of the steel wire, stabilize the steel ruler, and measure the distance on the platform. It takes one and a half hours to build and dismantle each working platform, and 5 people are required. After the gyro total station and total station are put into orientation work, except for the construction of working platforms in the middle tunnel with the coordinates of the first-level control points and the middle section at the end of the orientation, the construction of working platforms can be avoided in other middle sections. This causes problems such as the stability of the steel ruler and distance measurement without the working platform. In order to solve the above problems, it is necessary to develop a "hook" tool for contact measurement of metal mine shafts. Utility Model Content
[0003] The purpose of the utility model is to provide a hook device for metal mine shaft connection measurement in response to the problems existing in the prior art, which can effectively reduce the construction of work platforms, reduce the number of operators, reduce the labor intensity of operations, reduce the input of materials and tools, and eliminate the need for personnel to work in the shaft. The safety factor is improved, and the damage to equipment and facilities in the shaft caused by falling materials due to mistakes when building the work platform is reduced.
[0004] To this end, the utility model adopts the following technical solutions:
[0005] A hook device for metal mine shaft connection measurement, comprising a support rod (6), a hook (9) being provided at the top of the support rod (6), the hook (9) comprising a stainless steel sheet (5), the stainless steel sheet (5) being wound around the support rod (6), a connecting column (4) being provided at the top of the support rod (6), a first hook finger (1), a second hook finger (2) and a third hook finger (3) being provided at the top of the connecting column (4), a glove ring (8) being provided at the bottom of the support rod (6), and the two being fixedly connected by a thin rope.
[0006] Furthermore, the intersection angle between the second hook finger (2) and the plane where the first hook finger (1) and the third hook finger (3) are located is 3-6°.
[0007] Furthermore, the outsides of the glove ring (8), the first hook finger (1), the second hook finger (2) and the third hook finger (3) are all wrapped with insulating tape (7).
[0008] The beneficial effects of the utility model are:
[0009] The utility model optimizes the directional measurement process of the shaft, avoids the construction of a working platform in the middle section, reduces the input of operators, materials and tools, and effectively reduces the labor intensity. At the same time, in terms of safety, it not only avoids the operators working in the shaft, which significantly improves the safety factor, but also reduces the risk of damage to equipment and facilities in the shaft due to falling materials caused by failure in building the working platform. Finally, the utility model also has the advantages of compact structure, easy processing, and convenient operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The technical solution of the utility model is described below in conjunction with the accompanying drawings and implementation methods.
[0014] like Figure 1 As shown, a hook device for metal mine shaft connection measurement comprises a support rod (6). Specifically, the support rod (6) is made of a φ2 stainless steel tube with a length of 2.5 meters. A hook (9) is provided at the top of the support rod (6). The hook (9) comprises a stainless steel sheet (5). The stainless steel sheet (5) is wound around the support rod (6). In addition, a glove ring (8) is provided at the bottom of the support rod (6), and the two are fixedly connected by a thin rope. Specifically, the glove ring (8) is riveted to the support rod by an elastic thin rope, and the length is suitable to ensure that it can cover the wrist.
[0015] like Figure 2 As shown, a connecting column (4) is provided on the top of the stainless steel sheet (5), and a first hook finger (1), a second hook finger (2) and a third hook finger (3) are provided on the top of the connecting column (4), and the second hook finger (2) forms an angle of 3° with the planes where the first hook finger (1) and the third hook finger (3) are located.
[0016] In addition, the outsides of the glove ring (8), the first hook finger (1), the second hook finger (2) and the third hook finger (3) are all wrapped with insulating tape (7).
[0017] Specifically, the hook handle (9) can be made of a stainless steel sheet with a length of 10 cm, a width of 8 cm and a thickness of 1.5 mm. The 10 cm long steel sheet is divided into two sheets with a length of 6 cm and a length of 4 cm. A 2 cm portion is left between the two steel sheets as a connecting column (4) and the two sheets are folded vertically. The 4 cm steel sheet is rolled back into a columnar shape and sleeved on the support rod and welded. The head of the 6 cm steel sheet is cut into three hook fingers with a length of 4 cm and a width of 1.5 cm. The middle hook finger is bent inward to ensure that the middle hook finger and the planes on which the two side fingers are located form an angle of 3°.
[0018] The utility model is used in the following process:
[0019] After the steel wire is lowered to the predetermined position, the staff member stands outside the shaft safety guardrail, puts the glove ring (8) on his wrist, holds the support rod (6), stretches the steel wire hanging from the shaft of the vertical shaft horizontally, uses the hook (9) to hook the steel wire and pulls it to the edge of the shaft, and sticks three laser reflectors with an angle of 120° to each other on the steel wire. The three reflectors are distributed at three vertical positions. The hook (9) is used to hook the steel wire and slowly return it to the free hanging position of the steel wire. The total station measures the angle and distance. Similarly, after the steel ruler is lowered to the predetermined position, the staff member stands outside the shaft safety guardrail, puts the glove ring (8) on his wrist, holds the support rod (6), stretches the steel ruler hanging from the shaft of the vertical shaft horizontally, and clamps the steel ruler between the first hook finger (1), the second hook finger (2) and the third hook finger (3). Pay special attention to the data marking surface of the steel ruler facing the measuring instrument, and ensure that the steel ruler is in the free hanging position of the steel ruler. The level instrument measures the height difference.
