A push-pull air door for mining

Abstract

The invention discloses a push-pull type air door for mining. The invention comprises a driving motor, a second pulley, a gear plate and teeth. When the air door is used normally, the operation of the driving motor drives the sliding door to slide on the inner wall of the U-shaped box. Since the gear plate rotates in opposite directions to the driven gear, two groups of sliding doors can be moved away from or towards each other, thus saving the space occupied by opening the doors, and the structure is simple and safe to use. The invention comprises a first pulley, a second belt strip, a threaded shaft and a limiting shaft. When a power outage occurs, the threaded shaft can be rotated by shaking the handle to move the threaded shaft up and down. The movement of the threaded shaft drives the door body to move up and down, thus preventing the air door from being unable to be opened when a power outage occurs, and improving the use effect of the push-pull type air door for mining.

Description

Technical Field

[0001] The invention belongs to the technical field of mine air doors, and in particular relates to a push-pull type mine air door. Background Art

[0002] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention, and should not necessarily be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0003] In the prior art, the door body of a mine damper is inconvenient to operate during opening and closing, has a complex structure, is difficult to maintain, and occupies a large amount of underground space when opening and closing the door. In order to meet the installation requirements of a mine damper, it is often necessary to provide a larger space in the area where the damper is set in the mine.

[0004] However, the applicant found that due to the particularity of the underground structure of the mining area, if the damper occupies a large structural range, especially a large space in the horizontal direction, that is, in an underground mine with a certain depth, increasing the excavation area can easily cause the collapse of the mining area, which can easily pose a safety hazard.

[0005] In addition, the applicant also found that the prior art is prone to the phenomenon that the damper cannot be opened during a power outage, rendering the damper unusable and preventing air from circulating in the mining area, which is also a dangerous situation. Therefore, providing a damper that can still be opened and closed during a power outage and occupies less space is an urgent problem to be solved in the coal mining field. Summary of the invention

[0006] In order to solve the technical problems existing in the prior art, one of the purposes of the present invention is to provide a push-pull air door for mining.

[0007] To achieve the above-mentioned object of the invention, one or more embodiments of the present invention disclose the following technical solutions:

[0008] A mining push-pull damper comprises: a door frame, a door body is arranged on the front end outer surface of the door frame, a control box is fixedly connected to the upper side of the front end outer surface of the door body, a driving motor is fixedly connected to the front end outer surface of the control box, the driving motor is connected to a connecting shaft, the connecting shaft runs through the control box, a second pulley is connected to the outer surface of the connecting shaft, a first belt strip is rotatably connected to the outer surface of the second pulley, a gear plate is also connected to the center position of the outer surface of the connecting shaft, a T-slot is provided on the lower end outer surface of the control box, a T-rod is slidably connected to the inner wall of the T-slot, the lower end of the T-rod is fixedly connected to the sliding door, teeth are welded on the upper end outer surface of the T-rod, the outer surface of the teeth is meshingly connected to a driven gear, and the driven gear moves relatively on the gear plate;

[0009] Rotary bearings are fixedly connected to both sides of the front end outer surface of the door frame, the inner wall of the rotary bearing is fixedly connected to the two ends of the threaded shaft, the outer surface of the threaded shaft is screwed with a threaded cylinder, the outer surface of the threaded shaft is welded with a pulley 1, and the outer surface of the pulley 1 is rotatably connected to a second belt strip.

[0010] A second object of the present invention is to provide a mining push-pull damper for use in the mining industry.

[0011] When the power supply system is normal, the system in the control box is used to realize the translation of the sliding door, and the blocking situation of the Liangshan sliding door is used to realize the opening and closing of the sliding door in the horizontal direction;

[0012] When the power supply system fails to work properly, threaded shafts, rotating bearings, pulleys and other devices are used to realize the vertical operation of the door body.

[0013] Compared with the prior art, one or more embodiments of the present invention achieve at least the following beneficial effects:

[0014] 1. In one or more embodiments of the present application, a driving motor, a second pulley, a gear plate and teeth are provided. When the damper is used normally, the operation of the driving motor drives the sliding door to slide on the inner wall of the U-shaped box. Since the gear plate and the driven gear rotate in opposite directions, the two groups of sliding doors can move away from each other or towards each other, saving the space occupied by opening the door. The structure is simple and safe to use.

[0015] 2. In one or more embodiments of the present application, a pulley 1, a second belt strip, a threaded shaft and a limit shaft are provided.

[0022] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0023] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0024] As mentioned above, there are some problems in the use of current mine dampers, such as the damper switch area is greatly affected or the damper cannot be used normally when the power system is insufficient. Based on the above problems, this application proposes a mine push-pull damper, which reduces the damper influence range and provides a backup solution for the damper switch that does not rely on electricity. Thereby improving the comprehensive use effect of the damper. That is, a mine push-pull door is proposed, including the following structure:

[0026] Rotary bearings are fixedly connected to both sides of the front end outer surface of the door frame, the inner wall of the rotary bearing is fixedly connected to the two ends of the threaded shaft, the outer surface of the threaded shaft is screwed with a threaded cylinder, the outer surface of the threaded shaft is welded with a pulley 1, and the outer surface of the pulley 1 is rotatably connected to a second belt strip.

[0027] Due to the complex geological structure of the mining area, improper setting of the damper, especially the damper taking up too much space in the horizontal direction, can easily cause the collapse of the underground mining area. In this application, the mutual cooperation of the T-slot and the T-rod is used to limit the movement direction of the door body, so that in the horizontal direction of the underground mining area, excluding the power equipment, the area occupied is almost only the size of the door body.

[0028] In order to prevent the damper from being unable to open normally in the event of a power outage, the present application proposes a replacement solution for opening the damper in the vertical direction. The staff can lift the damper as a whole. Although there are certain requirements for the height, the door frame plays a supporting role in the height direction. Therefore, the process of moving the door body will not affect the underground environment of the mining area.

[0029] Furthermore, an additional connecting shaft is provided on either side of the two pulleys, and a driven gear is fixed on the connecting shaft.

[0030] In some embodiments, in order to realize the movement of the door body, the present application proposes that a T-shaped rod is provided above the sliding door and fixedly connected to the sliding door. Furthermore, the T-shaped rod is fixed to the sliding door by welding.

[0031] In some embodiments, in order to facilitate the opening and closing of the sliding door using the T-bar and the T-slot, a U-shaped box is provided under the sliding door in the present application to achieve auxiliary fixation of the sliding door.

[0032] Furthermore, the inner wall of the U-shaped box is slidably connected with a sliding door.

[0033] In some embodiments, in order to enable staff to open and close the damper during a power outage, an operating box is set at one end of the door frame in the present application, and the inner wall of the operating box is movably connected with a rotating rod, and the outer surface of the upper end of the rotating rod is connected with a handle, and the rotating rod is rotatably connected to the operating box through a bearing; thereby, the rotating rod is driven to rotate by the handle, and the rotating rod finally drives the threaded shaft to rotate.

[0034] Furthermore, the number of the pulleys 1 is 2 sets, and the other pulley 1 is welded to the outer surface of the rotating rod.

[0035] In some embodiments, in order to achieve normal opening and closing of the damper without power supply, rotating bearings are provided at the four corners of the door frame in the present application.

[0036] In some embodiments, in order to improve safety performance during use, a limit shaft and a sleeve are provided in the present application, and the limit shaft and the sleeve are used to maintain the parallel state of the door body and the door frame. The outer surface of the limit shaft is slidably connected with the sleeve, and the limit shaft is rotatably connected to the rotating bearing.

[0037] In some embodiments, in order to ensure the stability of the door body when moving up and down, the number of the sleeves and threaded cylinders is two.

The T-shaped rod 16 is welded and fixed to the sliding door 8. A U-shaped box 18 is set below the sliding door to achieve auxiliary fixation of the sliding door 8. The inner wall of the U-shaped box 18 is slidably connected with the sliding door 8. An operation box 2 is provided at one end of the door frame 1, and a rotating rod 22 is movably connected to the inner wall of the operation box 2. A handle 19 is connected to the outer surface of the upper end of the rotating rod 22. The rotating rod 22 is rotatably connected to the operation box 2 through a bearing; thus, the rotating rod 22 is driven to rotate by the handle 19, and the rotating rod 22 finally drives the threaded shaft 3 to rotate. There are two groups of pulleys 21, and another pulley 1 is welded to the outer surface of the rotating rod. In order to realize the normal opening and closing of the damper without power supply, a rotating bearing 4 is provided at the four corners of the door frame 1 in this application. In order to improve the safety performance during use, a limit shaft 9 and a sleeve 10 are provided in this application, and the limit shaft 9 and the sleeve 41 are used to keep the door body 5 parallel to the door frame 1. The outer surface of the limit shaft 9 is slidably connected to the sleeve 10, and the limit shaft 9 is rotatably connected to the rotating bearing 4.

[0041] The working principle and use process of the present invention: A mining push-pull damper of the present invention, when the damper is used normally, the operator connects the connecting line of the driving motor 6 to the power supply, operates the switch to start the driving motor 6, and the operation of the driving motor 6 drives the connecting shaft 24 to rotate, and the rotation of the connecting shaft 24 drives the gear plate 12 and the second pulley 23 to rotate. The rotation of the second pulley 23 drives the driven gear 15 to rotate under the action of the first belt strip 13 and the gear plate 12. Under the action of the teeth 14, the rotation of the gear plate 12 drives the sliding door 8 to slide on the inner wall of the U-shaped box 18, and the rotation of the driven gear 15 drives another group of sliding doors 8 to slide on the inner wall of the U-shaped box 18. The directions of rotation of the wheel disc 12 and the driven gear 15 are opposite, so that the two sets of sliding doors 8 can move away from or towards each other, saving the space occupied by opening the doors, and the structure is simple and safe to use. When the power fails, the operator shakes the handle 19 to drive the rotating rod 22 to rotate. The rotation of the rotating rod 22 drives the threaded shaft 3 to rotate through the pulley 1 21 and the second belt strip 20. The rotation of the threaded shaft 3 causes the threaded cylinder 11 to move up and down, and the movement of the threaded cylinder 11 drives the door body 5 to move up and down. The setting of the limit shaft 9 and the sleeve 10 is conducive to keeping the door body 5 parallel to the door frame 1 when moving, preventing the phenomenon that the damper cannot be opened during a power outage, improving the use effect of the mining push-pull damper, and is more practical.
