[0002] Mines include coal mines, metal mines, non-metallic mines and chemical mines. Many complex technical problems in the mining stage need to be solved by mining surveying, such as setting curves, underground site development, level determination of mining, ore volume calculation, and comparison between the upper and lower parts of the well. Therefore, mining surveying is a very important part of ore mining. For example, if the tunnel penetration is not accurately measured, it cannot be excavated at will, otherwise a large number of tunnels will be scrapped, which will not only cause great waste, but also affect production and even cause accidents.

[0003] Daily measurement work in mines is easily affected by the environment, mining process, and production progress. Therefore, when working in the work area, it is necessary to complete the work tasks quickly, accurately, and quickly. When measuring, first determine the known wire point to set up a station, then hang a hammer on the known wire point, and then measure. However, the existing technology generally manually stretches the traction rope and fixes it on the wire point. Due to the high position of the wire point, the existing technology has certain safety hazards. In addition, the existing technology requires people to manually pull the traction rope after the hammer is aimed at the wire point, resulting in low measurement efficiency. Summary of the invention

DETAILED DESCRIPTION

[0031] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] Example 1

[0033] A reciprocating plumb bob frame that is easy to set up for mine surveying, such as Figure 1-5 As shown, it includes a first support frame 1, a first support frame 2 and a pushing component 3. The first support frame 2 is fixedly installed on the top of the first support frame 1. The interior of the first support frame 2 is a cavity structure. The first support frame 2 is provided with a pushing component 3 for providing power to the device.

[0034] The pushing assembly 3 includes an electric push rod 31, a support plate 32, a second support frame 33, a wedge frame 34, a first spring 35, a ratchet push frame 36, a second spring 37 and a telescopic cylinder 38. The electric push rod 31 is fixedly installed on the outer wall of the first support frame 2, one end of the electric push rod 31 is fixedly connected to the support plate 32, the support plate 32 is slidably connected to the second support frame 33, and the second support frame 33 is slidably connected to the wedge frame 34. One side of the wedge frame 34 is an inclined structure. A first spring 35 is connected between 34 and the second support frame 33, and is used to drive the wedge frame 34 to return to its original position. A ratchet push frame 36 is slidably connected to the first support frame 2, and the ratchet push frame 36 is in contact with the wedge frame 34. A second spring 37 is connected between the ratchet push frame 36 and the first support frame 2, and is used to drive the ratchet push frame 36 to return to its original position. A telescopic cylinder 38 is fixedly connected to the bottom of the first support frame 2, and the interior of the telescopic cylinder 38 itself can be telescoped, and the telescopic cylinder 38 and the ratchet push frame 36 are slidably matched.

Since the space between the first support frame 2 and the telescopic cylinder 38 is in a closed state, the downward movement of the ratchet push frame 36 will squeeze the air inside the first support frame 2, so that the gas between the inside of the first support frame 2 and the telescopic cylinder 38 can push the telescopic cylinder 38 and the device thereon to extend. The ratchet push frame 36 moves downward by one unit, and the telescopic cylinder 38 can extend by three units, which is convenient for subsequent measurement.

The traction rope 54 is wound around the winding frame 52, and the traction rope 54 passes through the fourth support frame 45. One end of the traction rope 54 is fixedly connected to the plumb bob body 55, and the plumb bob body 55 is a conical object cast from metal.

[0041] During the extension of the telescopic cylinder 38 and the device thereon, the winding frame 52 will unwind the traction rope 54, and the volute spring 53 will be stretched accordingly.

It will be stretched, so that the slotted friction frame 63 restricts the friction ring 64 and the device thereon by friction, so that the winding frame 52 no longer rotates, so that the traction rope 54 is in a taut state and can support the plumb body 55. In the process of the ratchet push frame 36 moving downward, through the cooperation of the pawl frame 72 and the torsion spring 73, the pawl frame 72 can temporarily jam the ratchet push frame 36 to prevent the ratchet push frame 36 from resetting. When the electric push rod 31 is retracted to four-fifths of the length, the electric push rod 31 is controlled to stop retracting, and then the staff can measure the relevant data.

[0046] During the downward movement of the support plate 32, the support plate 32 will push the wedge block 83 with the clamping column and the device thereon to move downward, and the fifth spring 821 will be compressed accordingly. Through the cooperation of the double guide groove plate 91 and the slotted push frame 92, the second support frame 93 will swing and separate from the plumb bob body 55 for easy measurement. Before the ratchet push frame 36 is reset, the wedge block 83 with the clamping column will contact the inclined surface on the wedge support frame 81, and the wedge support frame 81 will squeeze the wedge block 83 with the clamping column to move, and the sixth spring 84 will be compressed accordingly, so that the wedge block 83 with the clamping column is separated from the support plate 32, and the fifth spring 821 will be reset accordingly and drive the seventh support frame 82 and the device thereon to reset, and the second support frame 93 will be reset accordingly.
