Description

Technical Field

[0001] The utility model relates to the field of measuring devices, in particular to a waist reference line measuring device for mine tunnel construction. Background Art

[0002] Mine tunnel construction refers to the process of building and maintaining underground passages for the purpose of excavating ore or performing other operations during mining. This process usually includes multiple links such as excavation, support, ventilation, and drainage to ensure the safety of miners and the effective extraction of mineral resources. During the construction of mine tunnels, it is very important to ensure the correct direction and slope of the tunnel. The centerline and waistline calibration of the tunnel are important reference lines to ensure the accuracy of the tunnel excavation direction and slope.

[0003] In the current waistline measurement process, the surveyor is usually required to hold a handheld rangefinder and calibrate the waistline reference point through a laser to complete the measurement of the waistline. However, during such operation, the rangefinder is often fixed to the ground by a bracket. The ground usually has a certain slope and may contain some gravel. During the measurement process, the rangefinder may be insufficiently stable, which may lead to inaccurate measurement results. In order to ensure the accuracy of the measurement results, multiple measurements and calibrations may be required, which may lead to low measurement efficiency.

[0004] Therefore, those skilled in the art provide a device for measuring the waist reference line in mine tunnel construction to solve the problems raised in the above background technology. Utility Model Content

The measuring device combines a directional rod and a rangefinder together, is easy to operate, and can quickly complete the waist line measurement work.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A waist reference line measuring device for mine tunnel construction comprises a main body, a protection mechanism is provided at the lower end of the main body, and two anti-slip mechanisms are provided at the upper end of the main body;

[0008] The main body includes a directional rod, the upper end of the directional rod near the front and rear ends are fixed with hooks, and the front end of the directional rod is clamped with a rangefinder;

[0010] The two anti-slip mechanisms both include short columns. A vertical baffle is fixedly provided at one end of the two short columns close to the rangefinder, and a limit block is slidably provided at one end of the upper end of the two short columns away from the rangefinder.

[0011] The protection block is fixedly arranged at the lower end of the directional rod, and the rear end of the telescopic block is tightly fitted with the rangefinder.

[0012] The two control switches are electrically connected to the two air pumps respectively, and the front and rear ends of the inflatable airbag are communicated with the two air pumps respectively.

[0013] A No. 1 spring is fixedly arranged on the inner bottom surface of the fixed block, and the lower end of the telescopic block is fixedly connected to the upper end of the No. 1 spring.

[0014] A connecting rope is fixedly provided on the upper ends of the two vertical baffles, and the two short columns are slidably sleeved in the two hanging buckles respectively.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model proposes a waist reference line measuring device for mine tunnel construction. The measuring device is provided with a directional rod and a rangefinder, wherein the directional rod can be fixed by two hooks. The slope of the directional rod is adjusted by adjusting the height of the two hooks to align it with the waistline reference point. The adjustment process is fast and flexible. The rangefinder can be directly fixed on the directional rod, and the direction of the laser emitted by the rangefinder is parallel to the center line of the directional rod. In this way, the rangefinder can complete the rapid measurement, improve the measurement efficiency, avoid the influence of the instability of the bracket fixing the rangefinder on the measurement process, ensure the stable operation of the rangefinder, and thus improve the accuracy of the measurement results.

The limit block can slide up and down to limit the hanging buckle, and has a certain anti-falling effect. In addition, when the device accidentally falls off, when the control switch is hit, the air pump can be activated to deploy the airbag to provide buffering protection for the directional rod and the rangefinder. This can prevent the device from accidentally falling off to a certain extent and provide protection when the device falls. The dual protection mechanism helps to enhance the durability of the device and helps to extend its service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] Reference Figure 1 The utility model provides an embodiment: a waist reference line measuring device for mine tunnel construction, comprising a main body 1, a protection mechanism 2 is provided at the lower end of the main body 1, and two anti-slip mechanisms 3 are provided at the upper end of the main body 1;

[0027] Specifically, the main body mechanism 1 is the main structure of the measuring device, in which the orientation rod 101 and the rangefinder 103 are combined together to facilitate the measurement of the center waistline. The protection mechanism 2 is located at the lower end of the main body mechanism 1. When the measuring device falls, the airbag can provide buffering protection for the device. The anti-slip mechanism 3 is a structure for fixing the device. Through the two anti-slip mechanisms 3, the device can be stably fixed at a specified height with a specified slope.

[0028] Reference Figure 2 The main body mechanism 1 includes a directional rod 101, the upper end of the directional rod 101 is fixedly provided with a hook 102 near the front and rear ends, and the front end of the directional rod 101 is clamped with a rangefinder 103;

[0029] Specifically, the directional rod 101 is made of a straight stainless steel material that is not easily deformed. Its dimensions are 1.2 meters long, a square hollow tube with a cross-section of 25 mm × 50 mm, and a wall thickness of 1 mm. The hook 102 is a thin sheet with a circular hole, which can be combined with the anti-slip mechanism 3 to quickly fix the measuring device. The height change of the two hooks 102 drives the slope change of the waistline. The rangefinder 103 uses the SNDWWAY-WS-TA120 model for distance measurement. The rangefinder 103 is a laser source. The direction of the laser it emits is parallel to the center line of the directional rod 101, which can ensure that the laser passes through the directional rod 101 and points to a specific position. The outer diameter of the rangefinder 103 is connected to the inner diameter of the directional rod 101, which can make the rangefinder 103 directly snap-fit ​​to the directional rod 101.

[0030] Reference Figure 3 The protection mechanism 2 includes a protection block 201. A control switch 202 is fixedly provided at the lower end of the protection block 201 near the front and rear ends. An air pump 203 is fixedly provided inside the protection block 201 near the front and rear ends. An inflatable airbag 204 is fixedly provided near the middle of the protection block 201. A fixed block 205 is fixedly provided at one end of the protection block 201 near the rangefinder 103. A telescopic block 206 is slidably provided on the upper end of the fixed block 205.

[0031] The protective block 201 is fixedly mounted on the lower end of the directional rod 101. The rear end of the telescopic block 206 is tightly fitted with the rangefinder 103. The two control switches 202 are electrically connected to the two air pumps 203, respectively. The front and rear ends of the inflatable airbag 204 are in communication with the two air pumps 203, respectively. A No. 1 spring 207 is fixedly mounted on the inner bottom surface of the fixed block 205. The lower end of the telescopic block 206 is fixedly connected to the upper end of the No. 1 spring 207.

[0032] Specifically, the protection block 201 is located at the lower end of the directional rod 101. When the device falls accidentally, it can protect the main body mechanism 1 at the upper end. The front and rear ends of the lower end of the device are both provided with control switches 202. When the device falls to the ground, the control switch 202 at the lower end that falls first is squeezed by the ground, which can start the corresponding air pump 203, and then inflate the inflatable airbag 204. The two sides of the protection block 201 are hollow. The inflated inflatable airbag 204 can be opened from both sides of the protection block 201 to provide buffering protection for the device. The telescopic block 206 can slide up and down in the fixed block 205 under the action of the No. 1 spring 207. The telescopic block 206 is located at the front end of the rangefinder 103. Since the rangefinder 103 is directly connected to the directional rod 101, the telescopic block 206 can prevent the rangefinder 103 from falling off accidentally.

[0033] Reference Figure 4The two anti-slip mechanisms 3 each include a short column 303 , and a vertical baffle 302 is fixedly provided at one end of the two short columns 303 close to the rangefinder 103 , and a limit block 305 is slidably provided at one end of the upper end of the two short columns 303 away from the rangefinder 103 ;

[0034] The upper ends of the two vertical baffles 302 are fixedly provided with a connecting rope 301, and the two short columns 303 are slidably sleeved in the two hooks 102. The two vertical baffles 302 are respectively located at the front ends of the two hooks 102, and the two limit blocks 305 are respectively located at the rear ends of the two hooks 102. The inner bottom surfaces of the two short columns 303 are fixedly provided with a No. 2 spring 304, and the lower ends of the two limit blocks 305 are respectively fixedly connected to the upper ends of the two No. 2 springs 304;

[0035] Specifically, the upper end of the connecting rope 301 is directly fixed at the specified midline position, and the length of the connecting rope 301 is adjustable. The vertical baffle 302 and the short column 303 form a structure with a hook function, wherein the limit block 305 can slide up and down in the short column 303 under the action of the No. 2 spring 304. The short column 303 is sleeved in the middle of the hook 102. The limit block 305 and the vertical baffle 302 clamp the hook 102 in the middle. The limit block 305 can play a certain anti-falling role. The upper end of the limit block 305 is semicircular and can slide up and down when subjected to horizontal thrust.

[0036] Working Principle: When using the measuring device, the distance meter 103 needs to be placed on the upper end of the telescopic block 206. A certain pressure is applied to the telescopic block 206. The telescopic block 206 contracts downward under the pressure, and the No. 1 spring 207 contracts. Then, the distance meter 103 is moved horizontally toward the directional rod 101 until the distance meter 103 is inserted into one end of the directional rod 101. The telescopic block 206 moves upward under the elastic force of the No. 1 spring 207, and the distance meter 103 is stably connected to the directional rod 101.

[0037] When the lifting rod 101 is lifted, the lifting rod 102 is lifted and the lifting device 103 is tightened, so that the lifting rod 101 is tightened and the lifting device 103 is tightened.
