Description

Technical Field

[0001] The utility model belongs to the technical field of underground penetration measurement, in particular to a marking device for underground tunnels. Background Art

[0002] Underground penetration measurement is an important part of determining the construction site. Early underground penetration measurement was basically to measure the field data underground, and to obtain the coordinate azimuth of the center line of the tunnel and the slope of the waistline of the tunnel by calculation. This coordinate azimuth and slope are consistent with the original design, and the difference is within the allowable range. At the same time, the pointing angles at the two end points of the tunnel are calculated, and the center line and waistline of the tunnel are calibrated at both ends of the tunnel using the above data, indicating that the tunnels are excavated separately according to the same slope as designed until they are correctly connected to each other at the penetration meeting point. There are only two reliable known points in the mine, but there is no line of sight. The underground wire control measurement is completed under the existing conditions, and the coordinate system must be consistent with the original one. The instrument used is a total station.

[0003] When using a total station to calibrate the line position underground, it is necessary to ensure that the total station is in a horizontal state. When surveying on some uneven working surfaces, the staff generally observes the level and then makes appropriate adjustments to the support legs. The intuitive judgment of the staff is not accurate enough, resulting in a lack of verification of the accuracy of the measured data. Therefore, a marking device for underground tunnels is needed, which can monitor the horizontality of the total station in real time and issue a warning to notify the staff to level the total station to avoid the situation where the data measured by the total station in a non-horizontal state is used. Utility Model Content

[0004] The purpose of the utility model is to provide a marking device for underground tunnels, which can monitor the horizontality of a total station in real time and issue a warning to inform the staff to level the total station to avoid the situation where data measured by the total station in a non-horizontal state is used, so as to solve the technical problems raised by the above-mentioned background technology.

[0005] The utility model provides a technical solution to the above-mentioned technical problems as follows: a marking device for underground tunnels, comprising a platform: a total station and legs are respectively installed on the top and bottom of the platform, a controller, a buzzer and a spherical shell are fixedly installed on the bottom of the platform by bolts, a rolling ball is routable connected to the inner wall of the spherical shell, a vertical rod is integrally formed at the bottom of the rolling ball, a vertical plate is fixedly connected to the bottom of the platform, a pressure sensor is arranged at the bottom end of the vertical plate, a cross bar is welded to the surface of the vertical plate, a slide plate is slidably connected to the surface of the cross bar, a spring is fixedly connected between the slide plate and the cross bar, and a top rod is welded to the inner wall of the slide plate.

[0006] Preferably, a bottom ball is welded to the bottom end of the vertical rod, an opening matching the vertical rod is formed at the bottom of the ball shell, and a guard ring is adhered to the inner wall of the opening.

[0007] Preferably, a pressure ring is sleeved on the surface of the pressure sensor, and the pressure ring is fixedly connected to the vertical plate by bolts.

[0008] Preferably, the inner wall of the slide plate is integrally formed with two symmetrically arranged clamping blocks, and the surface of the cross bar is provided with sliding grooves matched with the clamping blocks.

[0009] Preferably, the buzzer and the pressure sensor are electrically connected to the controller via wires.

[0010] 1. The beneficial effect of the utility model is that the vertical rod is always vertical under the action of gravity. If the platform is not horizontal, the vertical rod squeezes the top rod to move and exerts force on the pressure sensor, and then the pressure sensor transmits the signal to the controller and controls the buzzer to sound an alarm, so as to achieve real-time monitoring of the horizontality of the total station and issue a warning to inform the staff to level the total station, so as to avoid the use of data calculated by the total station in a non-horizontal state.

[0011] 2. The utility model shields and protects the opening at the bottom of the ball shell by setting a guard ring, thereby avoiding the direct contact and wear between the ball shell and the vertical rod.

[0012] 3. The utility model facilitates the disassembly and assembly of the pressure sensor by setting the pressure ring, thereby improving the convenience of the later maintenance of the pressure sensor.

[0013] 4. The utility model limits the movement of the slide plate on the surface of the crossbar by using the block and the slide groove in coordination, thereby preventing the slide plate from shaking during movement. BRIEF DESCRIPTION OF THE DRAWINGS

In case of wear and tear, a vertical plate 11 is fixedly connected to the bottom of the carrier 1, and a pressure sensor 12 is arranged at the bottom end of the vertical plate 11. A pressure ring 13 is sleeved on the surface of the pressure sensor 12, and the pressure ring 13 is fixedly connected to the vertical plate 11 by bolts.

A spring 16 is fixedly connected between the slide plate 15 and the cross bar 14, and a top rod 17 is welded to the inner wall of the slide plate 15.

[0024] Embodiment 2:

[0025] Figure 1-4The utility model shows an embodiment of an underground tunnel marking device, which includes a platform 1: a total station 2 and a leg 3 are respectively installed on the top and bottom of the platform 1, a controller 4, a buzzer 5 and a ball shell 6 are fixedly installed on the bottom of the platform 1 by bolts, a rolling ball 7 is rotatably connected to the inner wall of the ball shell 6, a vertical rod 8 is integrally formed at the bottom of the rolling ball 7, a vertical plate 11 is fixedly connected to the bottom of the platform 1, a pressure sensor 12 is arranged at the bottom end of the vertical plate 11, a cross bar 14 is welded on the surface of the vertical plate 11, and a slide plate is slidably connected to the surface of the cross bar 14 15, a spring 16 is fixedly connected between the slide plate 15 and the cross bar 14, a top rod 17 is welded to the inner wall of the slide plate 15, and two symmetrically arranged blocks 18 are integrally formed on the inner wall of the slide plate 15.

The buzzer 5 and the pressure sensor 12 are electrically connected to the controller 4 through wires.

[0026] Working principle: When the utility model is used, the user always keeps the vertical rod 8 vertical under the action of gravity. If the platform 1 is not horizontal, the vertical rod 8 drives the ball 7 to roll in the inner cavity of the spherical shell 6 and squeezes the top rod 17, and then the top rod 17 moves and applies force to the pressure sensor 12. At this time, the top rod 17 drives the spring 16 to deform, and then the pressure sensor 12 transmits the signal to the controller 4 and controls the buzzer 5 to sound an alarm. Then the staff adjusts the support legs 3. When the total station 2 is level again, the vertical rod 8 is reset to be vertical to the bottom of the spherical shell 6. At the same time, the rebound force of the spring 16 drives the top rod 17 to reset through the slide plate 15 and no longer squeezes the pressure sensor 12, thereby realizing real-time monitoring of the horizontality of the total station and issuing a warning to inform the staff to level the total station to avoid the situation where the data measured by the total station in a non-horizontal state is used.

[0027] To sum up: the underground tunnel marking device is always vertical under the action of gravity through the vertical rod 8. If the platform 1 is not horizontal, the vertical rod 8 squeezes the top rod 17 to move and exerts force on the pressure sensor 12, and then the pressure sensor 12 transmits the signal to the controller 4 and controls the buzzer 5 to sound an alarm, so as to achieve real-time monitoring of the horizontality of the total station and issue a warning to inform the staff to level the total station to avoid the data calculated by the total station in a non-horizontal state from being used.
