[0002] The ore pass system is the throat of the underground mine transportation system and plays a very important role in the mine production process. To realize the transfer of ore and waste rock, a series of ore passes need to be constructed in the mine development system. Especially near the main hoisting system, a main ore pass needs to be constructed to realize the transfer function of ore and waste rock. However, during the production process, due to many factors such as rough ore pass walls, ore accumulation, the existence of long strip large blocks, and too long slag accumulation time, the ore passes often show phenomena such as arching and blockage, seriously affecting mine production and even causing production stoppage in the subsequent ore dressing process.

[0003] The patent specification with the publication number CN113503783A discloses a blasting device and blasting method for ore pass blockage based on mine high-pressure water, including an explosive loading platform, a loading platform chassis, a high-pressure water pipe, and a wireless remote control; an infrared ranging sensor is provided on the upper surface of the explosive loading platform, the loading platform chassis supports the explosive loading platform, a water channel is provided inside the loading platform chassis, the water channel is communicated with the high-pressure water pipe, and a water spraying port is provided in the water channel; a communication module is further provided on the loading platform chassis, and the communication module is respectively connected to the infrared ranging sensor and the wireless remote control. The above device conducts blasting for ore pass blockage based on the blasting device for ore pass blockage with mine high-pressure water, which is easy to operate, safe and reliable, accurate and efficient, has a good dredging effect, and low cost.

[0004] However, it is found in the implementation of the related technology that the above technical solution has the following problems: when using the ranging instrument to measure the position of ore blockage during the use of the above device, if there is water vapor in the ore pass, it is difficult to accurately measure the position of ore blockage, and the ore pass may collapse at any time, so people cannot enter. Therefore, further improvement is needed. Content of the Utility Model

[0005] The utility model provides a measuring device for the position of ore blockage, which solves the problem that it is not convenient to measure the position of ore blockage in the related technology.

[0006] The technical solution of the utility model is as follows:

[0007] The measuring device for the position of ore blockage includes a base, a hydraulic push rod is fixedly connected to the upper end of the base, a measuring component is fixedly connected to the upper end of the hydraulic push rod, the measuring component includes a top plate fixedly connected to the upper end of the hydraulic push rod, and a rotating ring is rotatably connected to the outer surface of the top plate.

[0008] Preferably, positioning and fixing holes are uniformly formed through the upper end of the base.

[0009] Preferably, a circular groove is formed in the upper end of the top plate, a motor is arranged inside the circular groove, an annular groove is formed on the outer surface of the top plate, and a first telescopic rod is fixedly connected to the upper end of the top plate.

[0016] Preferably, the rotating shaft passes through the inside of the circular groove and is fixedly connected to the output end of the motor.

[0017] The working principle and beneficial effects of the present utility model are as follows:

[0018] The present utility model controls the second telescopic rod to extend and retract to push the second telescopic rod closer to the inner wall of the ore pass, controls the motor to drive the rotating shaft to rotate, and under the action of the bent connecting rod, the rotating shaft drives the swivel ring to rotate, and the swivel ring drives the second telescopic rod and the extended collision plate to rotate inside the ore pass. Controls the hydraulic push rod to push the top plate upward. When the top plate moves to the position where the ore is blocked, the top plate is blocked by the ore, causing the hydraulic push rod to be unable to continue moving upward, and the extended collision plate is blocked by the ore, causing the second telescopic rod and the extended collision plate to be unable to rotate normally, so that the swivel ring cannot rotate along the annular groove.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0026] As Figure 1 shown, this embodiment proposes an ore blockage position measuring device, including a base 1, the upper end of the base 1 is fixedly connected with a hydraulic push rod 2, and the upper end of the hydraulic push rod 2 is fixedly connected with a measuring component 3.

[0027] As Figure 1 shown, the upper end of the base 1 is uniformly and perforated with positioning and fixing holes 11, and the positioning and fixing holes 11 are used to fix the base 1 at the bottom of the ore pass.

[0028] As Figure 2As shown, the measuring assembly 3 includes a top plate 31 fixedly connected to the upper end of the hydraulic push rod 2. A circular groove 311 is formed in the upper end of the top plate 31. A motor is arranged inside the circular groove 311. An annular groove 312 is formed on the outer surface of the top plate 31. A first telescopic rod 313 is fixedly connected to the upper end of the top plate 31. The upper end of the first telescopic rod 313 is fixedly connected to a drill rod body 3131. The drill rod body 3131 is used to drill the ore to crush it. The first telescopic rod 313 is used to push the drill rod body 3131 to move closer to the ore. And the first telescopic rod 313 is a rotatable telescopic rod. When the first telescopic rod 313 rotates, the drill rod body 3131 rotates accordingly. The annular groove 312 is used to limit the rotating ring 32 to prevent the rotating ring 32 from detaching from the top plate 31. The motor arranged inside the circular groove 311 is used to drive the rotating shaft 3231 to rotate.

[0029] As Figure 3 As shown, a rotating ring 32 is rotatably connected to the outer surface of the top plate 31. A warning light 321 is fixedly connected to the outer surface of the rotating ring 32. A second telescopic rod 322 is fixedly connected to the outer surface of the rotating ring 32. One end of the second telescopic rod 322 is fixedly connected to an extended collision plate 3221. The rotating ring 32 is rotatably connected to the annular groove 312. A bent connecting rod 323 is also fixedly connected to the outer surface of the rotating ring 32. One end of the bent connecting rod 323 is fixedly connected to a rotating shaft 3231. The rotating shaft 3231 passes through the inside of the circular groove 311 and is fixedly connected to the output end of the motor. The extended collision plate 3221 is used to touch the inner wall of the ore pass. The second telescopic rod 322 is used to push the extended collision plate 3221 to move closer to the inner wall in the ore pass. The rotating shaft 3231 is used to drive the bent connecting rod 323 to rotate. The bent connecting rod 323 is used to drive the rotating ring 32 to rotate along the annular groove 312. The warning light 321 is used to monitor the rotation of the rotating ring 32 and give a warning to the outside.

[0030] The working principle and usage instructions of the present utility model are as follows: When it is necessary to measure the blocked position of the ore inside the ore pass, first, the staff needs to take out the measuring device. Then, the staff needs to fix the base 1 to the bottom of the ore pass through the positioning fixing holes 11. Next, the external control can be used to extend and retract the second telescopic rod 322 to push the second telescopic rod 322 closer to the inner wall of the ore pass. After the extended collision plate 3221 touches the inner wall of the ore pass, the second telescopic rod 322 is shortened back so that the extended collision plate 3221 cannot directly touch the inner wall of the ore pass, but the second telescopic rod 322 still has a certain length. At this time, the motor built in the circular groove 311 can be controlled to drive the rotating shaft 3231 to rotate. At this time, under the action of the bent connecting rod 323, the rotating shaft 3231 will drive the rotating ring 32 to rotate along the annular groove 312. At this time, the rotating ring 32 will drive the second telescopic rod 322 and the extended collision plate 3221 to rotate inside the ore pass. Then, the hydraulic push rod 2 is synchronously controlled to push the top plate 31 upward. When the top plate 31 moves to the ore blocked position, the top plate 31 is blocked by the ore, causing the hydraulic push rod 2 to be unable to continue moving upward. At the same time, when the extended collision plate 3221 is blocked by the ore, the second telescopic rod 322 and the extended collision plate 3221 cannot rotate normally, that is, the rotating ring 32 cannot rotate normally along the annular groove 312. At this time, the warning light 321 will emit sound and light to the outside world, so as to give a warning to the outside world to remind the position of the ore blockage. At this time, the first telescopic rod 313 can be controlled to extend and retract until the drill rod body 3131 touches the lower end of the ore. Then, the first telescopic rod 313 is controlled to rotate, so that the drill rod body 3131 rotates at the lower end of the ore, thereby crushing the ore and dredging the ore blocked position. If the ore is too hard and the drill rod body 3131 cannot crush the ore, after the warning light 321 warns and reminds the recorded position, other methods of blasting are used to dredge the ore blocked position.

[0031] The above is only the preferred embodiment of the present utility model, and it is not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
