[0026] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0027] In the present disclosure, unless otherwise specified, "inside" and "outside" refer to the inside and outside of the contour of the corresponding component. Furthermore, the terms "first" and "second" used in the present disclosure are to distinguish one element from another and have no order or importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0028] according to Figure 1 As shown, in the first aspect of the present disclosure, a fire door structure for a mine tunnel fire fighting system is provided, which is used to block smoke and fire in time when an emergency occurs underground. The fire door structure may include a mine tunnel rock layer 2 and a door body 1, the mine tunnel rock layer 2 may include a mine tunnel 230 and a first mounting groove 210 arranged on the side wall of the mine tunnel 230, and the door body 1 is configured to be able to move between the first mounting groove 210 and the mine tunnel 230, so that the mine tunnel 230 can be closed and opened through the door body 1.
[0029] Through the above technical solution, a door body 1 capable of moving between the first installation groove 210 and the mine passage 230 is provided. When a fire occurs, the mine passage 230 can be closed in time to prevent the fire from spreading. The door body 1 can be moved into the first installation groove 210, and sufficient space can be provided for the entry and exit of staff and work vehicles, which is conducive to the evacuation of personnel and avoidance of collision between the work vehicle and the door body 1.
[0030] In some possible implementations, for example, referring to Figure 1 As shown, the fire door structure may further include a driving mechanism 3 connected to the door body 1 for driving the door body 1 to move from the mine passage 230 to the first installation groove 210 to shorten the opening and closing time of the door body 1.
[0031] In some possible implementations, for example, referring to Figure 1 As shown, the first mounting groove 210 can be located at the top of the door body 1, so that the door body 1 can enter or move away from the first mounting groove 210 along the first direction X. Through the above-mentioned arrangement, when the door body 1 is located in the first mounting groove 210, the door body 1 can fall into the mine tunnel 230 more quickly due to gravity without any stop, thereby closing the mine tunnel 230.
[0032] In some possible implementations, for example, referring to Figure 1As shown, the driving mechanism 3 may include a fixing member 310, a transmission wheel 320, a traction member 330 and a driving member 340. The fixing member 310 is disposed in the first mounting groove 210, the transmission wheel 320 is connected to the fixing member 310, and the traction member 330 is disposed around the transmission wheel 320 and connected to the door body 1 at one end and connected to the driving member 340 at the other end. The driving member 340 is used to drive the traction member 330 to lift the door body 1 through the transmission wheel 320 to improve the stability of the fire door structure of the present disclosure.
[0033] Among them, the fixing member 310 can be an anchor rod or a soil nail. The present disclosure does not make any specific limitations on this. As long as it can achieve the function of fixing and bearing the transmission wheel 320, technical personnel in this field can make adaptive adjustments according to the actual needs.
[0034] The structure of the driving member 340 can be adaptively adjusted according to the actual needs. For example, the driving member 340 can include a driving motor and a winch connected to the output end of the driving motor. The traction member 330 is arranged on the winch. The driving motor drives the winch to rotate and drive the traction member 330 to be recovered to achieve the lifting of the door body 1. The driving member 340 can also include a winch with a rotating handle. The staff can operate the rotating handle to achieve the lifting of the door body 1. The present disclosure is not limited to this.
[0035] The traction member 330 may be a steel wire rope or other adaptive flexible structures, but the present disclosure is not limited thereto, and those skilled in the art may make adaptive adjustments according to actual needs.
[0036] Optionally, the number of the driving mechanisms 3 can be at least two, and the two driving mechanisms 3 are arranged at intervals. For example, the two driving mechanisms 3 can be arranged at intervals on opposite sides of the top of the door body 1 along the second direction Y, so that the door body 1 can achieve balance on both sides during the lifting process and will not tilt toward one side. It is more stable and safe. The second direction Y is perpendicular to the first direction X.
[0037] In some possible implementations, for example, referring to Figure 1 As shown, the mine tunnel stratum 2 may further include a second mounting groove 220 disposed on the side wall of the mine tunnel 230 and used for sliding connection of opposite sides of the door body 1. The second mounting groove 220 is provided to provide a guide for the lifting and lowering of the door body 1.
[0038] In some possible implementations, for example, referring to Figure 1As shown, the fire door structure may further include a support member 4 disposed in the second mounting groove 220, the support member 4 being configured to stop the door body 1 from falling, and the support member 4 being further configured to be able to move toward the second mounting groove 220 so that the door body 1 can fall to the mine tunnel 230. By providing the support member 4, the load of the drive mechanism 3 can be reduced, so that the drive mechanism 3 does not need to remain in a working state for a long time, thereby extending the service life of the drive mechanism 3.
[0039] Optionally, the support member 4 may be configured as an electrically-operated telescopic support rod.
[0040] The structural limitation of the support member in the present disclosure is only for the present disclosure, and the structure of the support member 4 can be adaptively adjusted according to the needs of the actual situation. For example, the support member 4 can include a first sleeve, a second sleeve slidably connected to the first sleeve, and a cylinder, the second sleeve is located inside the first sleeve, and the cylinder is connected to the second sleeve to drive the second sleeve to move in a direction away from the first sleeve, wherein the second sleeve can be constructed as a solid cylinder, and the cylinder can be replaced by an electric push rod. The present disclosure is not limited to this, and those skilled in the art can make adaptive adjustments according to the needs of the actual situation.
[0041] In some possible implementations, for example, referring to Figure 1 As shown, the number of the support members 4 can be at least two, and the two support members 4 are respectively located in the two second mounting grooves 220 on the opposite sides of the door body 1. By arranging two support members 4 in the two second mounting grooves 220 on the opposite sides of the door body 1, the support members 4 can stop the door body 1 more stably, effectively improving safety and stability.
[0042] In some other practicable embodiments, the first mounting groove 210 may also be located on any side of the door body 1 along the second direction Y or on two opposite sides along the second direction Y, so that the door body can move in the second direction Y to enter or move away from the first mounting groove 210; the second mounting groove 220 may also be located on two opposite sides of the door body 1 along the first direction X, and the door body 1 is slidably connected to the two second mounting grooves 220 on two opposite sides along the first direction X; the driving mechanism 3 may also include a slider and a slide rail, the slide rails are respectively arranged in the two second mounting grooves 220, the slider is arranged on two opposite sides of the door body 1 along the first direction X and is slidably connected to the slide rails, and mounting holes may be provided in the two second mounting grooves 220, and the mounting holes are used to install the support member 4, so that the support member 4 can be retracted into the mounting hole in the unactivated state without affecting the movement of the door body 1; the support member 4 can move in the direction away from the mounting hole in the activated state to stop the movement of the door body 1. The door body 1 can also open or close the mine tunnel 230, and the present disclosure does not make specific limitations on this.
[0043] According to a second aspect of the present disclosure, there is provided a mine fire fighting system, comprising at least one fire door structure, the fire door structure having all the beneficial effects of the above specific embodiments.
[0044] The number of fire door structures can be adaptively adjusted according to actual needs. For example, the number of fire door structures can be four or six, and they can be arranged at intervals in the mine tunnel underground to further enhance the safety of underground operations.
[0045] The present disclosure describes the working process of the fire door structure by way of example. For example, first, a first installation groove 210 and a second installation groove 220 are opened on the side wall of the mine rock layer 2 according to the actual situation. A hole is drilled in the first installation groove 210, and an anchor rod is assembled. A transmission wheel 320 is fixedly installed by the anchor rod. A traction member 330 is wound around the transmission wheel 320. One end of the traction member 330 is connected to the door body 1, and the other end is connected to the driving member 340. An electric telescopic support rod is installed in the second installation groove 220. The electric telescopic support rod can be located in the first installation groove 210. At the junction with the mine tunnel 230, the door body 1 is driven to rise and move into the first installation groove 210 by the driving member 340. For example, the driving member 340 can also use a winch to start the electric telescopic support rod so that the electric telescopic support rod is extended to stop the door body 1 from falling. In this way, the driving member 340 can stop working for a short time after raising the door body 1; when encountering a fire, the electric telescopic support rod is controlled to retract, and the door body 1 is not stopped and falls into the mine tunnel 230 along the second installation groove 220 under the action of gravity, thereby realizing the rapid closure of the mine tunnel 230.
[0046] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0047] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0048] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
