Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary mine-going downhill, in particular to an auxiliary mine-going downhill device. Background Art

[0002] Mining is the technology and science of extracting mineral resources from the earth's crust and surface. Mining in a broad sense also includes the mining of coal and oil. The mining industry is an important raw material industry. Metal ores are the main raw materials for the smelting industry, and non-metallic ores are important chemical raw materials and building materials. Mining can be divided into open-pit mining and underground mining. When mining ore underground, workers need to go down into the mine through a downhole device.

[0003] For example, a mining downhole device disclosed in the Chinese invention patent with publication number CN109650224A is provided with a groove, which cooperates with the slide rod and the slip ring, so that the lifting frame can drive the slip ring to slide back and forth on the slide rod when lifting. This effectively enhances the stability of the lifting frame during the lifting process and avoids shaking and tilting, which causes physical discomfort to the workers. By providing a slide groove and cooperating with the slider, the lifting plate can drive the slider to slide back and forth inside the slide groove. By providing a shock-absorbing spring, the lifting plate can squeeze the shock-absorbing spring when descending. Through the elastic force of the shock-absorbing spring, the lifting frame can play a certain shock-absorbing role, which effectively enhances the stability of the lifting frame landing.

[0004] Although this structure can be retracted through the crawler and drive the lifting frame to move up and down, the device does not have an anti-fall function. When in use, it affects the safety of construction workers. Therefore, we propose a mining auxiliary descent device that can prevent the lifting frame from falling to improve the safety of construction workers going down the mine. Utility Model Content

[0005] The purpose of the utility model is to provide an auxiliary downhole device for mining to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary device for going down into the well for mining, comprising a going down into the well equipment, a lifting frame is arranged inside the going down into the well equipment, a crawler is arranged outside the lifting frame, and a processing component is arranged inside the going down into the well equipment, the processing component includes a locking component arranged inside the going down into the well equipment, and a shock-absorbing component is arranged below the locking component.

[0007] Preferably, the locking assembly includes a mounting block fixedly mounted on the outer wall of the lifting frame, a gear rotatably arranged inside the mounting block, a rotating column fixedly sleeved inside the gear, a hook hinged on the outer wall of the rotating column, a first spring fixedly mounted on the outer wall of the hook, a stop block fixedly mounted on the end of the first spring away from the hook, a disc fixedly mounted on the outer wall of the mounting block, a locking hook fixedly mounted inside the disc, a limiting plate fixedly mounted on the top surface of the mounting block, and a rack meshing with the gear.

[0008] Preferably, the shock-absorbing assembly includes a fixed block fixedly mounted on the inner wall of the downhole equipment, an air pipe is sleeved inside the fixed block, an air bag is connected to one end of the air pipe, a second spring is arranged inside the air pipe, a sealing ring is slidably arranged on the end of the air pipe away from the air bag, and a sliding rod is fixedly mounted on the side of the sealing ring away from the second spring.

[0009] Preferably, the outer wall of the rotating column fixedly sleeved inside the gear is rotatably connected to the inside of the mounting block, and the limit plate is slidably arranged inside the rack at one end away from the lifting frame. Under its restriction, the meshing of the gear and the rack can be made more precise and stable.

[0010] Preferably, there are four hooks, which are divided into two groups and symmetrically distributed about the center line of the gear. The stop block is fixedly installed on the outer wall of the rotating column. Under its restriction, when the rotating column rotates stably, the centrifugal force on the hook is small, and under the elastic action of the first spring fixedly installed on the outer wall of the stop block, the hook is pulled toward the stop block to avoid the hook from being engaged with the lock hook.

[0011] Preferably, one end of the second spring is fixedly mounted to the inner wall of the trachea, and the end of the second spring away from the inner wall of the trachea is fixedly mounted to the side of the sealing ring away from the sliding rod, and the sliding rod that is not squeezed can be pushed upward under the action of the elasticity of the second spring.

[0012] Preferably, there are eight tracheas, which are symmetrically distributed about the center line of the airbag, so that when the outer wall of the sealing ring and the inner wall of the trachea seal and slide, the sealing ring pushes the gas inside the trachea to inflate the airbag.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The auxiliary mining device is composed of a locking assembly as one of its components. When it is necessary to carry out the mine operation, the mine equipment can be used to carry out the mine operation. The existing mine equipment raises and lowers the lifting frame by contracting the crawler. When the crawler breaks, the lifting frame will fall naturally, endangering the safety of the construction workers. It is necessary to carry out anti-fall treatment. When the lifting frame falls, the gears set inside the mounting block fixed on the outer wall of the lifting frame are quickly meshed, so that the gears rotate quickly, and the rotating column set inside the gear rotates quickly. Since the hook is hinged with the rotating column, when the centrifugal force increases, the hook deflects with the hinged position with the rotating column as the rotation center, so that the hook The locking hook inside the disc fixed to the outer wall of the mounting block is engaged to limit the rotating gear so that it does not rotate, thereby achieving the effect of preventing falling. When the lifting frame does not fall, its descending speed is uniform and the hook is subjected to small centrifugal force. Under the action of the first spring elasticity, the hook is pulled toward the block so that the hook does not contact the locking hook, allowing the gear to rotate normally for downhole transportation operations. Due to the sliding arrangement of the limit plate and the rack inside, the meshing of the gear and the rack can be made more stable under its restriction (the downhole equipment, lifting frame and crawler are existing public technologies in the comparative documents, so their structures are not fully described in this case).

[0015] 2. The auxiliary mining device is composed of a shock-absorbing component as one of its components. When the lifting frame is about to reach the bottom of the equipment, it falls. In order to prevent the locking component from intervening in time, the sliding rod can be pushed and squeezed through the bottom of the lifting frame to make the sealing ring fixed at the end of the sliding rod slide inside the air pipe, and the inside of the airbag is quickly inflated through the air pipe. The lifting frame is shock-absorbing by the inflated airbag to minimize the harm to the construction workers. When the lifting frame rises, the sliding rod is not squeezed, and the sealing ring is pushed upward under the action of the elasticity of the second spring arranged inside the air pipe to deflate the airbag, thereby preventing the airbag from being in an inflated state for a long time and extending the service life of the airbag.

DETAILED DESCRIPTION

[0023] Example 1

[0024] A preferred embodiment of the auxiliary mining device provided by the utility model is as follows Figures 1 to 6 As shown: an auxiliary mine-going device for mining, comprising a mine-going device 1; a lifting frame 2 is arranged inside the mine-going device 1; a crawler 3 is arranged outside the lifting frame 2; and a processing component 4 is arranged inside the mine-going device 1, the processing component 4 comprises a locking component 41 arranged inside the mine-going device 1, the locking component 41 comprises a mounting block 411 fixedly mounted on the outer wall of the lifting frame 2, a gear 412 is rotatably arranged inside the mounting block 411, a rotating column 413 is fixedly sleeved inside the gear 412, a hook 414 is hinged on the outer wall of the rotating column 413, a first spring 415 is fixedly mounted on the outer wall of the hook 414, a stopper 416 is fixedly mounted on the end of the first spring 415 away from the hook 414, a disc 417 is fixedly mounted on the outer wall of the mounting block 411, a locking hook 418 is fixedly mounted inside the disc 417, a limiting plate 419 is fixedly mounted on the top surface of the mounting block 411, and the gear 412 is meshed with a rack 4111.

[0025] In this embodiment, when it is necessary to carry out downhole operations, the downhole equipment 1 can be used to carry out the downhole work. The existing downhole equipment 1 raises and lowers the lifting frame 2 by contracting the crawler 3. When the crawler 3 breaks, the lifting frame 2 will fall naturally, endangering the safety of the construction workers, and anti-falling treatment is required. When the lifting frame 2 falls, the gear 412 rotatably arranged inside the mounting block 411 fixedly mounted on its outer wall quickly meshes, causing the gear 412 to rotate quickly, and the rotating column 413 sleeved inside the gear 412 rotates quickly accordingly. Since the hook 414 is hinged to the rotating column 413, when the centrifugal force increases, the hook 414 deflects with the hinged position with the rotating column 413 as the rotation center, so that the hook 414 and the disc 4 fixedly mounted on the outer wall of the mounting block 411 are The locking hook 418 inside 17 is engaged to limit the rotating gear 412 so that it will not rotate, thereby achieving the effect of preventing it from falling. When the lifting frame 2 does not fall, its descending speed is uniform, the hook 414 is subjected to little centrifugal force, and under the elastic action of the first spring 415, the hook 414 is pulled opposite to the block 416, so that the hook 414 will not contact the locking hook 418, so that the gear 412 can rotate normally for downhole transportation operations. Since the limiting plate 419 is internally slidingly arranged with the rack 4111, under its restriction, the engagement between the gear 412 and the rack 4111 can be made more stable (the downhole equipment 1, the lifting frame 2 and the crawler 3 are existing public technologies in the comparative documents, so their structures are not fully described in this case).

[0026] Furthermore, the outer wall of the rotating column 413 fixedly sleeved inside the gear 412 is rotatably connected to the inside of the mounting block 411, and the end of the limiting plate 419 away from the lifting frame 2 is slidably set inside the rack 4111. Under its restriction, the engagement between the gear 412 and the rack 4111 can be made more precise and stable.

[0027] Furthermore, there are four hooks 414, which are divided into two groups and are symmetrically distributed about the center line of the gear 412. The stopper 416 is fixedly installed on the outer wall of the rotating column 413. Under its restriction, when the rotating column 413 rotates stably, the hook 414 is subjected to little centrifugal force. Under the elastic action of the first spring 415 fixedly installed on the outer wall of the stopper 416, the hook 414 is pulled toward the stopper 416 to prevent the hook 414 from being engaged with the lock hook 418.

[0028] Example 2

[0029] On the basis of Example 1, a preferred embodiment of the auxiliary downhole device for mining provided by the utility model is as follows: Figures 1 to 6As shown: the shock-absorbing component 42 includes a fixed block 423 fixedly installed on the inner wall of the downhole equipment 1, an air pipe 422 is sleeved inside the fixed block 423, one end of the air pipe 422 is connected to an air bag 421, a second spring 424 is arranged inside the air pipe 422, a sealing ring 425 is slidably arranged on the end of the air pipe 422 away from the air bag 421, and a sliding rod 426 is fixedly installed on the side of the sealing ring 425 away from the second spring 424.

[0030] In this embodiment, when the lifting frame 2 is about to reach the bottom of the downhole equipment 1, it falls. In order to prevent the locking assembly 41 from intervening in time, the sliding rod 426 can be pushed and squeezed through the bottom of the lifting frame 2, so that the sealing ring 425 fixedly installed at the end of the sliding rod 426 slides inside the air pipe 422, and the air bag 421 is quickly inflated through the air pipe 422. The lifting frame 2 is cushioned by the inflated air bag 421 to minimize damage to the construction personnel. When the lifting frame 2 rises, the sliding rod 426 is not squeezed, and under the elastic action of the second spring 424 set inside the air pipe 422, the sealing ring 425 is pushed upward to deflate the air bag 421, thereby preventing the air bag 421 from being in an inflated state for a long time, thereby extending the service life of the air bag 421.

[0031] Furthermore, one end of the second spring 424 is fixedly installed on the inner wall of the trachea 422, and the end of the second spring 424 away from the inner wall of the trachea 422 is fixedly installed on the side of the sealing ring 425 away from the sliding rod 426. Under the elasticity of the second spring 424, the sliding rod 426 that is not squeezed can be pushed upward.

[0032] In addition, there are eight air tubes 422 symmetrically distributed about the center line of the airbag 421 , so that when the outer wall of the sealing ring 425 and the inner wall of the air tube 422 are sealed and slid, the sealing ring 425 pushes the gas inside the air tube 422 to inflate the airbag 421 .

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
