Technical Field

[0001] The invention relates to the technical field of escape devices, in particular to a safety escape device used in coal mines or tunnels. Background Art

[0002] Coal mines and tunnels are both excavated and constructed by human participation. During the excavation process, mines and tunnels may collapse due to natural disasters and human factors, which will block escape channels. Therefore, escape pipes were invented.

[0003] However, when the escape pipe is in use, the injured with limited mobility cannot be transferred quickly and still need the help of others to escape, which affects their own escape speed and takes up the escape space of others. In chaotic conditions, stampedes are likely to occur, increasing the casualties of the accident.

[0004] Therefore, in order to solve the above problems, a safety escape device for use in coal mines or tunnels is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a safety escape device for use in coal mines or tunnels, so as to solve the problem that when the escape pipe proposed in the above background technology is used, the injured with limited leg and foot mobility need to be supported by others to escape, which affects their own escape speed and occupies the escape space of others. In chaotic situations, trampling incidents are likely to occur, which will increase the casualties of the accident.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a safety escape device for use in coal mines or tunnels, comprising: an escape pipe, a movable door is slidably installed on the front side of the escape pipe, an escape structure is installed inside the escape pipe, the escape structure comprises a movable plate frame, the movable plate frame is installed inside the escape pipe, a roller is fixedly connected to the bottom surface of the movable plate frame, a connecting groove is provided on the top surface of the movable plate frame, a first gear is movably installed inside the movable plate frame, a second gear is meshingly connected to the upper side of the first gear, a rocker is fixedly installed on the side wall of the second gear, a guide rail is installed on the lower side of the movable plate frame, and a rack plate is installed on one side of the guide rail.

[0007] Preferably, an installation structure is installed on the upper side of the escape structure, and the installation structure includes a first fixed plate, the first fixed plate is fixedly installed on the top wall on the inner side of the escape pipe, a guide rod is fixedly installed inside the first fixed plate, a first slider is slidably installed on the guide rod, a spring is fixedly connected to the side wall of the first slider, a first scissors arm is hinged on the bottom surface of the spring, a second scissors arm is hinged on the bottom end of the first scissors arm, and a connecting block is hinged on the bottom end of the second scissors arm.

[0008] Preferably, a slot is provided on the bottom surface of the connecting block, a first pin is inserted into the slot, a second slider is inserted into the front surface of the connecting block, a second fixed plate is fixedly installed on the top surface of the movable plate frame, a threaded hand rod is movably installed inside the second fixed plate through a bearing, an insert block is fixedly connected to the bottom surface of the threaded hand rod, and a second pin is inserted into the front surface of the insert block.

[0009] Preferably, the escape duct is of tubular structure and is made of ultra-high molecular weight polyethylene material, and the movable door is of arc-shaped structure.

[0010] Preferably, the first gear is located just above the rack plate, and the bottom end of the first gear is exposed from the bottom surface of the movable plate frame. There are two groups of guide rails, which are respectively located on both sides of the rack plate.

[0011] Preferably, the spring is sleeved on the guide rod, and the other end of the spring is fixedly connected to the inner wall of the first fixed plate. There are two groups of the first scissor arms and the second scissor arms respectively, and the top ends of the two groups of the first scissor arms are hinged with first fixed blocks, and the first fixed blocks are fixedly installed on the bottom surface of the first fixed plate.

[0012] Preferably, the bottom ends of the two groups of the first scissor arms are hinged to the top ends of the two groups of the second scissor arms respectively, and the bottom end of the other group of the guide rails is hinged with a second fixing block, and the second fixing block is fixedly mounted on the top surface of the second fixing plate.

[0013] Preferably, the first latch penetrates the connecting block and the second slider at the same time, the second slider is slidably mounted inside the second fixing plate, the threaded hand rod is threadedly connected to the second slider, and the insert block is fixed inside the connecting groove by the second latch.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the escape duct of the present invention has a slidable movable plate frame installed inside, and the injured with limited leg and foot movement can be quickly transferred by manually shaking the joystick, and multiple people can ride on one movable plate frame, which can alternately provide moving power for the movable plate frame, thereby speeding up the escape speed and improving the escape efficiency.

[0015] An escape pipe, an escape structure and an installation structure are provided. When a mine or tunnel collapses, the movable door can be pulled upward to open the movable door. At this time, the movable plate frame is in a suspended state, which can prevent the movable plate frame from blocking the escape of the escapee behind. By shaking the threaded hand rod, which is threadedly connected to the second slider, the second slider can be driven to slide inside the fixed block, so that the second slider is close to the second fixed block, so that a scissor effect occurs between the two sets of guide rails and the two sets of first fixed blocks, driving the fixed blocks to gradually descend, so that the movable plate frame gradually descends to the top surface of the guide rail, so that the roller is stored on the top surface of the guide rail, and the bottom end of the first gear will mesh with the top surface of the rack plate. At the same time, when the second slider approaches the second fixed block, the first slider will slide on the guide rod and squeeze the spring.

[0016] The first latch is then pulled out to release the fixed connection between the connecting block and the second slider. At this time, the connecting block is no longer fixedly connected to the second slider, and the threaded hand rod loses the fixation of the connecting block to the connecting block. Under the reaction force of the spring, the first slider moves away from the first fixed block, and the two sets of first scissor arms and the two sets of second scissor arms will have a reverse scissor action and reset. At the same time, the connecting block will move away from the second fixed block, and the connecting block will rise and reset, away from the mobile plate frame, so that the mobile plate frame remains on the top surface of the guide rail, and the connecting block is automatically and quickly retracted, which can prevent the user from having no time to reversely rotate the threaded hand rod after putting down the mobile plate frame. The rod retracts the connecting block and directly operates the mobile board frame for escape, so that the two sets of first scissor arms and the two sets of second scissor arms are always in a downwardly extended state, which will block the escape channel of the escapees at the rear side, and the mechanical transmission when rotating the fixed block will produce sound inside the escape channel, which can remind the escapees at the rear to control the mobile board frame to slow down in time. At the same time, by pulling out the second latch, the fixed block can be removed from the mobile board frame to free up more space, so that multiple people can take one mobile board frame, which can alternately provide power for the mobile board frame to speed up the escape and improve the efficiency of escape.

[0017] People with mobility impairments can manually shake the joystick to drive the second gear to rotate, and the second gear drives the first gear to rotate, and the first gear is engaged with the rack plate, which can drive the movable plate frame to move inside the escape pipe. The setting of the roller can reduce the friction between the movable plate frame and the escape pipe, making the movement of the movable plate frame more convenient and labor-saving, thereby increasing the probability of escape.

DETAILED DESCRIPTION

[0026] 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.

[0027] See also Figure 1-7 , an embodiment provided by the present invention:

[0028] The escape pipe 1, the first scissor arm 35 and the second scissor arm 37 used in the present application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described here in detail.

[0029] A safety escape device for use in a coal mine or tunnel comprises: an escape pipe 1, a movable door 11 is slidably installed on the front of the escape pipe 1, an escape structure 2 is installed inside the escape pipe 1, the escape structure 2 comprises a movable plate frame 21, the movable plate frame 21 is installed inside the escape pipe 1, a roller 22 is fixedly connected to the bottom surface of the movable plate frame 21, a connecting groove 23 is provided on the top surface of the movable plate frame 21, a first gear 24 is movably installed inside the movable plate frame 21, and the upper side of the first gear 24 is meshed with the connecting groove 23. A second gear 25 is connected, a rocker 26 is fixedly installed on the side wall of the second gear 25, a guide rail 27 is installed on the lower side of the movable plate frame 21, and a rack plate 28 is installed on one side of the guide rail 27. By installing a slidable movable plate frame 21 inside the escape pipe 1, the injured with limited leg and foot movement can be quickly transferred by manually shaking the rocker 26, and multiple people can ride on one movable plate frame 21, which can alternately provide power for the movable plate frame 21 to speed up the escape speed and improve the escape efficiency.

[0030] Furthermore, a mounting structure 3 is installed on the upper side of the escape structure 2, and the mounting structure 3 includes a first fixed plate 31, which is fixedly installed on the top wall inside the escape pipe 1, and a guide rod 32 is fixedly installed inside the first fixed plate 31, and a first slider 33 is slidably installed on the guide rod 32, and a spring 34 is fixedly connected to the side wall of the first slider 33, and a first scissor arm 35 is hinged on the bottom surface of the spring 34, and a second scissor arm 37 is hinged on the bottom end of the first scissor arm 35, and a connecting block 39 is hinged on the bottom end of the second scissor arm 37. The spring 34 provides power for the automatic and rapid retraction of the connecting block 39, so that the first scissor arm 35 and the second scissor arm 37 can be automatically retracted after the movable plate frame 21 is lowered, so as to prevent the first scissor arm 35 and the second scissor arm 37 from drooping all the time, causing the escapee who moves quickly at the rear side to hit it without braking in time, causing the escape pipe 1 to be blocked, which is prone to trampling incidents and will increase casualties in the accident.

[0031] Furthermore, a slot 310 is provided on the bottom surface of the connecting block 39, a first pin 311 is inserted inside the slot 310, a second slider 312 is inserted on the front surface of the connecting block 39, a second fixing plate 313 is fixedly installed on the top surface of the movable plate frame 21, a threaded hand rod 314 is movably installed inside the second fixing plate 313 through a bearing, a plug block 315 is fixedly connected to the bottom surface of the threaded hand rod 314, a second pin 316 is inserted on the front surface of the plug block 315, the slot 310 provides a position for the installation of the second slider 312, the first pin 311 can fix the second slider 312 and the connecting block 39 together, so as to quickly release the connection between the connecting block 39 and the second slider 312, and realize the rapid retraction of the connecting block 39.

[0032] Furthermore, the escape duct 1 is a tubular structure and is made of ultra-high molecular weight polyethylene material. The movable door 11 is an arc-shaped structure. The escape duct 1 has good impact resistance, light weight, wear resistance, and a long service life. The escape duct 1 can be prevented from being deformed by external force, causing the guide rail 27 and the rack plate 28 to bend.

[0033] Furthermore, the first gear 24 is located directly above the rack plate 28, and the bottom end of the first gear 24 is exposed from the bottom surface of the movable plate frame 21. There are two groups of guide rails 27, and the two groups of guide rails 27 are respectively located on both sides of the rack plate 28. After the movable plate frame 21 is lowered, the first gear 24 can engage with the rack plate 28, and the first gear 24 cooperates with the rack plate 28 to provide power for the movement of the movable plate frame 21.

[0034] Furthermore, the spring 34 is sleeved on the guide rod 32, and the other end of the spring 34 is fixedly connected to the inner wall of the first fixed plate 31. There are two groups of first scissor arms 35 and second scissor arms 37 respectively. The top end of the other group of first scissor arms 35 is hinged with a first fixed block 36, and the first fixed block 36 is fixedly installed on the bottom surface of the first fixed plate 31. The spring 34 provides power for the automatic and rapid reset of the first slider 33 away from the first fixed block 36 and the connecting block 39.

[0035] Furthermore, the bottom ends of the two groups of first scissor arms 35 are hinged to the top ends of the two groups of second scissor arms 37 respectively, and the bottom end of the other group of guide rails 27 is hinged with a second fixed block 38, and the second fixed block 38 is fixedly installed on the top surface of the second fixed plate 313. The first scissor arms 35 cooperate with the second scissor arms 37 to lower the movable plate frame 21, and when stored, the volume is small and will not hinder the transfer by later people.

[0036] Furthermore, the first latch 311 passes through the connecting block 39 and the second slider 312 at the same time, the second slider 312 is slidably installed inside the second fixed plate 313, the threaded hand rod 314 is threadedly connected to the second slider 312, and the plug block 315 is fixed inside the connecting groove 23 through the second latch 316. The first latch 311 can connect the connecting block 39 and the second slider 312 together, and the disassembly and assembly are convenient. The rotation of the threaded hand rod 314 can drive the second slider 312 to move inside the second fixed plate 313, so that the second slider 312 is close to the second fixed block 38, and the two sets of first scissor arms 35 and the two sets of second scissor arms 37 all produce a scissoring effect, so that the movable plate frame 21 can be lowered.

[0037] Working principle: when a mine or tunnel collapses, the movable door 11 can be pulled upward to open the movable door 11. At this time, the movable plate frame 21 is in a suspended state, which can prevent the movable plate frame 21 from blocking the escape of the escapee behind. By shaking the threaded hand rod 314, the threaded hand rod 314 is threadedly connected to the second slider 312, which can drive the second slider 312 to slide inside the second fixed plate 313, so that the second slider 312 approaches the second fixed block 38, so that a scissor effect occurs between the two sets of guide rails 27 and the two sets of first fixed blocks 36, driving the second fixed plate 313 to gradually descend, so that the movable plate frame 21 gradually descends to the top surface of the guide rail 27, so that the roller 22 is stored on the top surface of the guide rail 27, and the bottom end of the first gear 24 will mesh with the top surface of the rack plate 28. At the same time, when the second slider 312 approaches the second fixed block 38, the first slider 33 will slide on the guide rod 32 and squeeze the spring 34.

[0038] Then, the first latch 311 is pulled out to release the fixed connection between the connecting block 39 and the second slider 312. At this time, the connecting block 39 is not fixedly connected to the second slider 312, and the fixing of the connecting block 39 by the threaded hand rod 314 is lost. Under the reaction force of the spring 34, the first slider 33 moves away from the first fixed block 36, and the two sets of first scissor arms 35 and the two sets of second scissor arms 37 will have a reverse scissor action and reset. At the same time, the connecting block 39 will move away from the second fixed block 38, and the connecting block 39 will rise and reset, away from the movable plate frame 21, so that the movable plate frame 21 remains on the top surface of the guide rail 27, and the connecting block 39 is automatically and quickly retracted, which can prevent the user from having no time to react after putting down the movable plate frame 21. The connecting block 39 is retracted by rotating the threaded hand rod 314, and the mobile plate frame 21 is directly operated to escape, so that the two sets of first scissor arms 35 and the two sets of second scissor arms 37 are always in a downwardly extended state, which will block the escape channel of the escapee at the rear side, and the mechanical transmission when the second fixed plate 313 is rotated will produce a sound inside the escape duct 1, which can remind the escapee at the rear to control the mobile plate frame 21 to slow down in time. At the same time, by pulling out the second latch 316, the second fixed plate 313 can be removed from the mobile plate frame 21 to free up more space, so that multiple people can take one mobile plate frame 21, which can alternately provide power for the mobile plate frame 21 to speed up the escape and improve the efficiency of escape.

[0039] People with mobility impairments can manually shake the rocker 26 to drive the second gear 25 to rotate, and the second gear 25 drives the first gear 24 to rotate, and the first gear 24 engages with the rack plate 28, which can drive the movable plate frame 21 to move inside the escape duct 1. In addition, due to the provision of the roller 22, the friction between the movable plate frame 21 and the guide rail 27 can be reduced, making the movement of the movable plate frame 21 more convenient and labor-saving, thereby increasing the probability of escape.

[0040] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
