Description

Technical Field

[0001] The invention relates to the technical field of mine-specific air ducts, in particular to a mine-specific air duct with a protective structure. Background Art

[0002] Wind duct, also known as wind guide duct or ventilation pipe, is a flexible pipe connected to the fan equipment for extraction and exhaust to guide the air flow in a certain direction. It is the most commonly used air guide device. At present, the excavation work in the mine usually requires the installation of wind duct in the cave to discharge and release the harmful gas in the mine cave to ensure that the workers in the mine cave will not be harmed by toxic gases for a long time.

[0003] However, most of the mine-specific air ducts in the prior art have relatively poor protection measures when facing micro-collapse or vibration caused by the mine, resulting in the rocks generated by the micro-collapse or vibration of the mine hitting the air duct, causing deformation or damage to the surface, thereby directly affecting the service life of the air duct. In addition, the fixing effect of the air duct is usually unstable when it is subjected to micro-collapse or vibration of the mine, causing the air duct to easily roll down and cause damage to its surface or interior.

[0004] Therefore, the present invention provides a mine-specific wind tube with a protective structure to solve the above problems. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] The present invention provides a mine-specific wind duct with a protective structure, aiming to solve the problem that most of the mine-specific wind ducts in the prior art mentioned in the background technology will cause deformation or damage to the surface of the wind duct when the mine cave collapses or vibrates, thereby shortening its service life, and the wind duct is prone to rolling down when it collapses or vibrates, causing damage to its surface or interior.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a mine-specific wind duct with a protective structure, comprising a wind duct body, an outer shell is arranged above the wind duct body, a bottom shell is arranged below the wind duct body, a threaded rod is threadedly connected to the bottom shell, a threaded sleeve is threadedly connected to the outer surface of the threaded rod, the outer surface of the threaded sleeve is fixedly connected to the outer wall of the outer shell, a force-bearing block with an oblique arrangement on one side is fixedly connected to the outer wall of the outer shell, a connecting rod is fixedly connected to the outer wall of the force-bearing block, a positioning plate is fixedly connected to the end of the connecting rod that penetrates the outer shell away from the force-bearing block, and an extrusion block with an oblique arrangement on one side is fixedly connected to the outer wall of the bottom shell, and the extrusion block is adapted to the inclined surface of the force-bearing block.

[0009] As a preferred technical solution of the present application, an outer wall of the force-bearing block is fixedly connected with an adjusting rod, and one end of the adjusting rod away from the force-bearing block is fixedly connected to the outer wall of the shell.

[0010] As a preferred technical solution of the present application, a spring is fixedly connected to the outer wall of the force-bearing block, one end of the spring away from the force-bearing block is fixedly connected to the outer wall of the shell, and the adjusting rod is inserted into the inner circle of the spring.

[0011] As a preferred technical solution of the present application, a telescopic rod is fixedly connected to the outer surface of the threaded sleeve, and one end of the telescopic rod away from the threaded sleeve is fixedly connected to the outer wall of the bottom shell.

[0012] As a preferred technical solution of the present application, ventilation holes are provided on both sides of the outer shell, and a support block for placing the air duct body is fixedly connected to the bottom of the inner wall of the bottom shell.

[0013] As a preferred technical solution of the present application, the outer wall of the bottom shell is threadedly connected with a bolt, and one end of the bolt away from the bottom shell is fixedly connected with a stabilizing pad.

[0014] As a preferred technical solution of the present application, a moving wheel is fixedly connected to the bottom of the bottom shell, and a push handle is fixedly connected to the outer wall of the bottom shell.

[0015] (III) Beneficial effects

[0016] The present invention is provided with a motor, a threaded rod, a threaded sleeve, a shell, a bottom shell, an extrusion block, a force-bearing block and a positioning plate. When the motor drives the threaded rod to rotate, the threaded sleeve matched with the thread of the threaded rod can drive the shell to move downward, so that when the shell moves downward to contact and merge with the bottom shell, the air duct body can be protected to prevent the air duct body from being damaged by falling stones. In addition, during the downward movement of the shell, the force-bearing block can be driven to move downward synchronously, so that when the force-bearing block moves downward and contacts the extrusion block, the force-bearing block can utilize the inclined surface match with the extrusion block to make the force-bearing block pass The positioning plate can be driven to move inward through the connecting rod, so that the positioning plate can position the wind duct body, thereby ensuring the stability of the wind duct body. This device enables the wind duct body to have good protection measures when facing the micro-collapse or vibration caused by the mine, preventing the stones generated by the micro-collapse or vibration of the mine from directly hitting the wind duct body and causing deformation or damage to its surface, thereby avoiding affecting the service life of the wind duct body. In addition, the fixing effect of the wind duct body is relatively stable when it is subjected to the micro-collapse or vibration of the mine, preventing the wind duct from rolling down easily and causing damage to its surface or interior.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The present invention provides a mine-specific wind tube with a protective structure, such as Figure 1-5 As shown, the mine-specific wind duct includes a wind duct body 1, an outer shell 2 is arranged above the wind duct body 1, a bottom shell 3 is arranged below the wind duct body 1, a threaded rod 4 is threadedly connected to the bottom shell 3, the outer surface of the threaded rod 4 is threadedly connected to a threaded sleeve 6, the outer surface of the threaded sleeve 6 is fixedly connected to the outer wall of the outer shell 2, the outer wall of the outer shell 2 is fixedly connected to a force block 7 with an oblique arrangement on one side, the outer wall of the force block 7 is fixedly connected to a connecting rod 8, the end of the connecting rod 8 that penetrates the outer shell 2 away from the force block 7 is fixedly connected to a positioning plate 9, the outer wall of the bottom shell 3 is fixedly connected to an extrusion block 10 with an oblique arrangement on one side, and the extrusion block 10 is adapted to the inclined surface of the force block 7.

[0026] The output shaft of the motor 5 is used to drive the threaded rod 4 to rotate, so that when the threaded rod 4 is in a rotating state, the threaded sleeve 6 threadedly matched with it can drive the shell 2 to move downward, so that when the shell 2 moves downward to merge with the bottom shell 3, the air duct body 1 can be protected to prevent the air duct body 1 from being deformed or damaged by falling stones when the mine cave collapses or vibrates, thereby ensuring the service life of the air duct body 1 and avoiding certain property losses caused by its damage. In addition, the shell 2 can drive the force-bearing block 7 to move downward synchronously, so that when the force-bearing block 7 contacts the extrusion block 10, the inclined surface can be used to drive the force-bearing block 7 to move toward the inside of the shell 2 through the connecting rod 8, so that the positioning plate 9 can position the air duct body 1, ensuring that the fixing effect of the air duct body 1 is relatively stable when the mine cave collapses or vibrates, so that the air duct body 1 is not easy to roll down, thereby effectively avoiding damage to its surface or interior, and when the motor 5 drives the threaded rod 4 to rotate in the opposite direction, the shell 2 can move upward, so that the air duct body 1 is in an open state, which is convenient for the staff to inspect and maintain it.

[0027] An adjusting rod 11 is fixedly connected to the outer wall of the force block 7, and one end of the adjusting rod 11 away from the force block 7 is fixedly connected to the outer wall of the outer shell 2. A spring 12 is fixedly connected to the outer wall of the force block 7, and one end of the spring 12 away from the force block 7 is fixedly connected to the outer wall of the outer shell 2. The adjusting rod 11 is inserted into the inner circle of the spring 12.

[0028] By utilizing the cooperation between the adjusting rod 11 and the spring 12, the positioning plate 9 has an elastic adjusting force, so that when the positioning plate 9 contacts the wind tube body 1, it can be adaptively adjusted according to the size of the wind tube body 1 to prevent the positioning plate 9 from excessively squeezing the wind tube body 1 and causing deformation of its surface. The elastic force provided by the spring 12 allows the force block 7 to reset itself when it loses the squeezing of the squeezing block 10, so that the wind tube body 1 can be positioned while protecting it next time. The adjusting rod 11 makes the force block 7 not only have a moving point, but also have good stability, to prevent the force block 7 from being unstable due to the connection of the spring 12 alone.

[0029] A telescopic rod 13 is fixedly connected to the outer surface of the threaded sleeve 6 , and one end of the telescopic rod 13 away from the threaded sleeve 6 is fixedly connected to the outer wall of the bottom shell 3 .

[0030] The telescopic rod 13 provides the threaded sleeve 6 with a limit point, and the threaded sleeve 6 can also move up and down smoothly by utilizing the telescopic characteristics of the telescopic rod 13. Therefore, when the threaded sleeve 6 is restricted, the threaded rod 4 is in a rotating state, and the threaded sleeve 6 can move up and down smoothly, avoiding the situation where the threaded sleeve 6 has no limit point and rotates synchronously with the threaded rod 4.

[0031] Ventilation holes 14 are provided on both sides of the outer shell 2 , and a support block 15 for placing the air duct body 1 is fixedly connected to the bottom of the inner wall of the bottom shell 3 .

[0032] The vent 14 allows the outer shell 2 to have space for the air flow through the wind duct body 1, so that when the outer shell 2 and the bottom shell 3 are combined to protect the wind duct body 1, the wind duct body 1 can also replace and circulate the air in the mine, avoiding the outer shell 2 directly blocking the wind duct body 1 and making it unable to circulate air, and the support block 15 provides a placement point for the wind duct body 1.

[0033] The outer wall of the bottom shell 3 is threadedly connected with a bolt 16 , and one end of the bolt 16 away from the bottom shell 3 is fixedly connected with a stabilizing pad 17 .

[0034] The bolt 16 can drive the stabilizing pad 17 to move downward smoothly by utilizing the threaded fit with the bottom shell 3, and the friction force provided by the stabilizing pad 17 when in contact with the ground can effectively improve the stability of the device and prevent the device from moving unexpectedly.

[0035] A moving wheel 18 is fixedly connected to the bottom of the bottom shell 3 , and a push handle 19 is fixedly connected to the outer wall of the bottom shell 3 .

[0036] By utilizing the cooperation between the moving wheel 18 and the push handle 19 , the staff can move the device conveniently and labor-savingly, so that the device has the function of being moved to various positions to protect the wind tube body 1 .

[0037] Working principle:

[0038] When it is necessary to protect the wind duct body 1, first start the motor 5 so that the output shaft of the motor 5 drives the threaded rod 4 to rotate. When the threaded rod 4 rotates, the threaded sleeve 6 that is threadedly matched with the threaded rod 4 can drive the outer shell 2 to move downward, so that when the outer shell 2 moves downward to a suitable position, it can be merged with the bottom shell 3, thereby protecting the wind duct body 1, and the outer shell 2 can drive the force-bearing block 7 to move downward synchronously, so that when the force-bearing block 7 moves downward to contact with the extrusion block 10, the force-bearing block 7 can utilize the inclined surface between the extrusion block 10 to cooperate with the extrusion block 10 so that when the force-bearing block 7 is squeezed by the extrusion block 10, it can drive the connecting rod 8 to move inward, so that when the connecting rod 8 drives the positioning plate 9 to move inward, the wind duct body 1 can be positioned to improve the stability of the wind duct body 1.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
