[0002] The measurement of mined - out areas mainly refers to the work of measuring the areas that have been mined during the mining process in mines. The measurement of mined - out areas is very important for ensuring the safety of mines, reasonably planning the mining plan, and evaluating the remaining resources. In the prior art, when measuring mined - out areas, generally a three - dimensional laser scanner is used to measure data such as the terrain, vertical height, and overall area in the mine tunnel. When measuring, a measuring device usually needs to be temporarily erected to carry the three - dimensional laser scanner. However, since there are prone to dangerous accidents such as falling rocks and even collapses at the top of the mine tunnel, this not only easily damages the measuring tools but also poses a life threat to the measuring personnel. Therefore, there are serious safety hazards during the measurement. Content of the Utility Model

DETAILED DESCRIPTION

[0020] In this embodiment, refer to Figures 1-4, the void measurement device includes a three-dimensional laser scanner 7. The three-dimensional laser scanner 7 is installed on a front-back angle adjustment mechanism, and the front-back angle adjustment mechanism is installed on a left-right angle adjustment mechanism. The left-right angle adjustment mechanism is installed on a lifting mechanism. The lifting mechanism is installed in a measurement vehicle, and the measurement vehicle includes a vehicle body 1 and rollers 2. The rollers 2 are installed at the bottom of the vehicle body 1 and are used to drive the vehicle body 1 to move forward. A storage cavity 3 is provided in the vehicle body 1, and the lifting mechanism is installed in the storage cavity 3. After the front-back angle adjustment mechanism, the left-right angle adjustment mechanism, and the three-dimensional laser scanner 7 are lowered together by the lifting mechanism, they are stored in the storage cavity 3. A rotatable and openable protective plate 27 is installed on the vehicle body 1 near the storage cavity 3. After the three-dimensional laser scanner 7 is stored in the storage cavity 3, the protective plate 27 retracts to close the storage cavity 3, thereby playing a role in protecting the three-dimensional laser scanner 7.

[0021] The protective plate 27 includes two left and right halves, both of which are semi-circular structures. The two half protective plates 27 are respectively connected to the vehicle body 1 by hinges to form a structure that can rotate up and down. Thrust rods 29 are respectively provided at the two side edges of the front-back angle adjustment mechanism. When the thrust rods 29 rise with the front-back angle adjustment mechanism, the two half protective plates 27 are pushed open, thereby opening the storage cavity 3 and enabling the three-dimensional laser scanner 7 to rise smoothly.

[0022] The front-back angle adjustment mechanism includes a worm 14 and a worm gear 13. The worm 14 is connected to a steering motor 12. The worm gear 13 is installed on a rotating rod 11 and meshes with the worm 14. Both ends of the rotating rod 11 are respectively connected and fixed with mounting sleeves 8. The two mounting sleeves 8 are respectively movably installed on two mounting plates 10 to form a rotatable structure. The steering motor 12 and the two mounting plates 10 are both installed on a lifting plate 9, and the lifting plate 9 is installed on the left-right angle adjustment mechanism. A closing plate 4 is installed on the mounting sleeve 8. An installation frame 5 is fixed on the closing plate 4, and an installation disk 6 is fixed on the installation frame 5. The three-dimensional laser scanner 7 is installed on the installation disk 6.

[0023] The left-right angle adjustment mechanism includes an electric drive device and a lifting seat 16. The electric drive device is installed on the lifting mechanism, and the lifting seat 16 is movably inserted through the lifting mechanism. The electric drive device is connected to a cross plate 20. The cross plate 20 is connected to the bottom end of the lifting seat 16, and the top end of the lifting seat 16 is connected to the lifting plate 9 of the front-back angle adjustment mechanism. A displacement seat 17 that can move horizontally on the lifting mechanism is also provided on the lifting mechanism to avoid jamming during adjustment. The top end of the displacement seat 17 is connected to the bottom of the lifting plate 9 of the front-back angle adjustment mechanism to form a rotation fulcrum of the front-back angle adjustment mechanism.

[0024] The electric drive device adopts an electric push rod 19 (or a cylinder), and the cross plate 20 is fixedly connected to the telescopic rod of the electric push rod 19 (or the cylinder).

[0025] The lifting mechanism includes a lifting disc 18, and sliding sleeves 21 are respectively arranged on both sides of the lifting disc 18; a guide rod 22 and a screw rod 23 are arranged in the storage cavity 3 of the vehicle body 1, and the bottom end of the screw rod 23 is connected with a lifting motor 24; one of the sliding sleeves 21 is sleeved on the guide rod 22, and the other sliding sleeve 21 is in threaded connection with the screw rod 23.

[0026] Two limiting grooves 15 are arranged on the side wall of the storage cavity 3, and the guide rod 22 and the screw rod 23 are respectively installed in the two limiting grooves 15, so as to avoid occupying the space of the storage cavity 3.

[0027] A circular protection cylinder 25 is arranged around the storage cavity 3 at the top of the vehicle body 1, and two opposite notches 26 are arranged at the top of the protection cylinder 25. Two semi-protection plates 27 are respectively hinged and installed in the notches 26 through a rotating shaft and a torsion spring 28 to form a structure that can rotate up and down.

[0028] Guide grooves corresponding to the ejector rods 29 are respectively arranged on the inner surfaces of the two semi-protection plates 27. When the front and rear angle adjustment mechanism rises, the ejector rods 29 are embedded in the guide grooves.

[0029] Working principle: When measuring the inside of the mine tunnel, the three-dimensional laser scanner 7 measures the data inside the mine tunnel by means of the movement of the measuring vehicle. When it is necessary to adjust the angle of the three-dimensional laser scanner 7, the steering motor 12 can be used to drive the worm 14 to rotate. After the worm 14 rotates, it cooperates with the worm wheel 13 to drive the rotating rod 11 to rotate back and forth. The rotating rod 11 drives the mounting sleeve 8 to rotate back and forth, thereby driving the closing plate 4 to adjust the angle in the front and rear directions, that is, to realize the front and rear angle adjustment of the three-dimensional laser scanner 7. When it is necessary to adjust the angle in the left and right directions, the electric push rod 19 and the cross plate 20 cooperate synchronously to drive the lifting seat 16 to perform a vertical lifting movement. Since the height of the displacement column 17 does not change, when one side of the lifting seat 16 rises and falls, one side of the lifting disc 9 will be tilted, thereby completing the left and right angle adjustment of the three-dimensional laser scanner 7. After use, the lifting motor 24 can be used to drive the screw rod 23 to rotate. Since the movement track of the mounting disc 18 is restricted by the screw rod 23 and the guide rod 22, when the screw rod 23 rotates, it will synchronously drive the mounting disc 18 to perform a vertical movement, and then drive the upper parts to perform an overall movement, thereby driving the three-dimensional laser scanner 7 to perform a lifting movement. After being retracted into the storage cavity 3, at this time, since the protection plate 27 lacks the restriction of the ejector rod 29, under the action of the torsion spring 28, the protection plate 27 closes downward to close the storage cavity 3. When the three-dimensional laser scanner 7 rises, the ejector rod 29 is used to push open the protection plate 27 and compress the torsion spring 28.

[0030] The above has made a detailed description of the present invention. The above description is only a preferred embodiment of the present invention, and it cannot limit the implementation scope of the present invention. That is, all equal changes and modifications made according to the scope of this application should still fall within the scope covered by the present invention.
