Description

Technical Field

[0001] The utility model relates to the technical field of early warning devices for rock burst in gold mines, in particular to an early warning device for preventing and controlling rock burst in gold mines. Background Art

[0002] Gold mine refers to gold ore or gold deposit. Gold ore is a mineral aggregate with sufficient gold content and can be used industrially. Gold mine is a place where gold is obtained through mining operations. It is a certain scale of gold ore accumulation that can be used industrially formed through mineralization. The types of gold deposits are complex and diverse. There are mainly conglomerate type, greenstone belt type, quartz vein type, ductile shear zone type, Carlin type, porphyry type, epithermal type, volcanic rock type, Cenozoic placer type, etc.

[0003] Due to the uneven ground caused by gold mining, when the strain gauge enters the hole, the uneven ground will cause the strain gauge to contact the inner wall of the hole, causing damage to the strain gauge and resulting in economic losses. The existing device cannot adjust the depth of the strain gauge, and the depth of the strain gauge in the hole is fixed, which makes the stress gauge test inflexible. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an early warning device for preventing and controlling rock burst in gold mines, which has the advantages of good protection and flexible depth adjustment, and solves the problems raised by the above-mentioned background technology.

[0005] The utility model provides the following technical solution: an early warning device for preventing and controlling rock burst in a gold mine, comprising an outer shell, an inner wall of the outer shell being movably sleeved with a stress gauge, a pull rod being fixedly assembled on the top of the strain gauge, a clamping strip being fixedly assembled on the outer edge of the pull rod, a clamping slot being provided on the outer edge of the clamping strip, a mounting plate being fixedly assembled on the outer edge of the top of the outer shell, a circular hole being provided on the top of the mounting plate, three circular holes being provided in total, a nut being fixedly assembled on the top of the circular hole, an adjusting screw being threadedly connected to the inner wall of the nut, a contact plate being fixedly assembled on the bottom of the adjusting screw, and a level being fixedly assembled on the inner wall of the top of the pull rod.

[0006] As a preferred technical solution of the utility model, a plurality of the card slots are provided and are evenly distributed, and a card block is fixedly mounted on the top of the inner wall of the card slot.

[0007] As a preferred technical solution of the utility model, a connecting column is fixedly mounted on the top of the outer shell, a stopper is movably sleeved on the outer edge of the connecting column, and an end of the stopper away from the connecting column is located in the inner cavity of the slot.

[0008] As a preferred technical solution of the utility model, a limiting groove is provided at one end of the stopper away from the connecting column, and a paddle is fixedly mounted on the top of the stopper.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1. The early warning device for preventing and controlling rock burst in gold mines observes the spirit level. When the spirit level is not in a horizontal state, the three adjusting screws are adjusted. When the spirit level is in a horizontal state, the stress gauge is in a vertical state, thereby solving the problem that the ground is not flat enough due to the mining of gold mines. When the stress gauge enters the hole, the uneven ground will cause the stress gauge to contact with the inner wall of the hole, thereby causing damage to the stress gauge and causing economic losses.

[0011] 2. The early warning device for preventing and controlling rock burst in gold mines protects the stress gauge through the outer shell, through the coordinated use of the outer shell, the pull rod, the clamping strip and the block. The strain gauge can be extended from the outer shell by pushing the pull rod downward, and then the block is stuck in the slot on the clamping strip. At this time, the pull rod cannot be lowered, thereby increasing the service life of the strain gauge. At the same time, the depth of the strain gauge in the hole can be adjusted.

When the strain gauge 2 enters the hole, the contact piece 14 contacts the ground. Then, the three adjusting screws 13 are adjusted to make the strain gauge 2 in a vertical state. At this time, the strain gauge 2 will not contact the inner wall of the hole, which further improves the safety of the strain gauge 2. The inner wall at the top of the pull rod 3 is fixedly equipped with a spirit level 15.
