Description

Technical Field

[0001] The invention relates to the technical field of accident rescue training, and in particular to a mine roof fall and slab accident rescue training system. Background Art

[0002] In order to improve fire prevention awareness and safety awareness, people usually participate in fire drills and have personal experience. Through the experience of different projects, they can deepen their understanding of fire risks and improve their vigilance. Moreover, fire is a dangerous and urgent disaster event. Therefore, appropriate fire drills can improve the ability to respond quickly and calmly to fires. At the same time, in simulated fire scenes, it can increase the effectiveness of firefighters in avoiding blind escape in real fire accidents. Therefore, fire drills are an important part of firefighters' daily training. In current fire drills, there are multiple types of drills in different scenarios, and underground training is also one of the commonly used training components. Due to the particularity and complexity of underground training scenarios, a variety of different situations are required for simulated training.

[0003] When a fire occurs underground, roof collapse accidents are also common. Roof collapse refers to an accident in which a large area of ​​the roof or side walls collapses and causes injuries due to improper excavation or support during the excavation and lining of mines, tunnels, and culverts.

[0004] For example, the Chinese patent with the authorization announcement number "CN104850052 B" and the name "Fire Emergency Drill Simulation System and Simulation Method" provides a fire emergency drill simulation system and simulation method. The system includes a real fire system that can realistically simulate the scene of a fire on site to enhance the crisis awareness of trainees. The simulated well site equipment can provide trainees with a device for handling fires. The UWB positioning system can locate the escape position of trainees when the dangerous situation is under control or cannot be controlled.

[0005] The shortcomings of the existing technology are that, in the existing technology, especially in underground training, most of the training is only conducted through a real fire system such as the above-mentioned patent, and there is an even greater lack of drills for rescue of roof collapse and rock fall accidents, thereby failing to conduct comprehensive disaster prevention drills.

[0010] As a further preferred solution in the embodiment of the present invention, there are multiple baffles, and a rotatable baffle block is rotatably provided under each baffle, and the baffle block can be retracted into the baffle when it rotates.

[0011] As a further preferred solution in the embodiment of the present invention, a support plate is also rotatably arranged in the tunnel, and the rotation position of the support plate is set at the bottom of the two tunnels. After the trainee passes the position of the tunnel side collapse training module, the support plate rotates toward the inclined trough to dump the collapsed material into the inclined trough.

[0012] As a further preferred solution in the embodiment of the present invention, inclined plates are provided at both ends of the support plate, and the inclined directions of the inclined plates are toward the support plate.

[0053] It also includes a load-bearing component, which is arranged at the bottom of the tunnel. When the load-bearing component is under pressure, the load-bearing component drives the transmission mechanism to unlock the locking mechanism, so that the bearing mechanism opens and the collapsed objects fall.

[0054] Specifically, the present invention, through the coordinated use of the set load-bearing components and the transmission mechanism, and then through the coordinated use with the locking mechanism and the bearing mechanism, can achieve that when the trainee is under pressure, the first bearing plate 21 and the second bearing plate 22 are pressed downward, that is, they can drive the fixed block 411 to move downward, that is, the locking mechanism can be passively unlocked through the coordinated use of the transmission mechanism, that is, the collapsed objects on the bearing mechanism can fall, that is, collapse training can be performed.

[0055] In an embodiment further provided by the present invention, there are two supporting mechanisms, which include a containing frame 12 arranged on the tunnel wall 1 and a rotating plate 32 rotatably arranged below the containing frame 12, and a sliding plate 31 is slidably arranged on the rotating plate 32, and a locking mechanism is arranged on the sliding plate 31.

[0056] In an embodiment further provided by the present invention, side fixing plates 11 are provided above and below the containing frame 12, and the locking mechanism includes a guide shaft 33, and a locking block 331 is provided on the guide shaft 33 for sliding in the circumferential direction. The guide shaft 33 is inserted into a limiting slide groove 1101 provided on the side fixing plate 11, and a second locking groove 1103 adapted to the locking block 331 is provided above the limiting slide groove 1101. When the locking block 331 is inserted into the second locking groove 1103, the supporting mechanism is locked.

[0057] In an embodiment further provided by the present invention, the limiting groove 1101 is gradually opened from top to bottom in a direction close to the rotating plate 32. When the locking mechanism is unlocked, the rotating plate 32 and the sliding plate 31 move downward, and during the downward movement, the sliding plate 31 can gradually retract into the rotating plate 32 under the limiting guidance of the limiting groove 1101.

[0058] In an embodiment further provided by the present invention, the load-bearing assembly includes a second bearing plate 22 and a first bearing plate 21 rotatably arranged on the second bearing plate 22, and the transmission mechanism includes a driving rod 41 vertically slidingly arranged in the tunnel wall 1 and a fixed block 411 fixedly arranged below the driving rod 41, the fixed block 411 is below the first bearing plate 21, and the outer surface of the driving rod 41 is sleeved with a fourth elastic member 412, and one end of the fourth elastic member 412 is fixedly connected to the bottom of the driving block, and the other end is in contact with the tunnel wall 1, and under its elastic force, it can It is able to make the driving block 43 have a tendency to move upward, that is, it can make the fixed block press against the rotation axis position of the first supporting plate 21 and the second supporting plate 22, so that the interference block 421 is not inserted into the second locking groove 1103, and a supporting base plate 212 is provided below the first supporting plate 21 and the second supporting plate 22, and one end of the second supporting plate 22 is slidably provided on the supporting base plate 212. When the trainee steps on the second supporting plate or the first supporting plate, the second supporting plate 22 is triggered to slide along the supporting base plate 212, and then drives the fixed block 411 to move downward.

[0059] In an embodiment further provided by the present invention, a driving block 43 is fixedly provided above the fixed block 411, and a hinged movable rod 44 is rotatably provided at one end of the driving block 43, and a transmission rod 441 is rotatably provided at one end of the hinged movable rod 44, and a hinged rod 42 is rotatably provided at one end of the transmission rod 441, and a hinged rod 42 is rotatably provided at one end of the transmission rod 441, and the hinged rod 42 is rotatably provided in the side fixed plate 11, and a resistance block 421 is rotatably provided at the other end of the transmission rod 441, and one end of the resistance block 421 is inserted into the second locking groove 1103. When the load-bearing component is under pressure, the resistance block 421 is driven to move into the second locking groove 1103 through the transmission mechanism, so that the locking block 331 disengages from the second locking groove 1103.

[0060] Specifically, the first supporting plate 21 and the second supporting plate 22 are provided with a lifting device on the top, which can drive the first supporting plate 21 and the second supporting plate 22 to rise. After the collapse training is completed, the trainee passes through the second supporting plate 22, and then the lifting device drives the load-bearing component to move upward. At this time, the collapsed object is on the load-bearing component, and then the load-bearing component moves upward with the load-bearing component. Then, during the upward movement, the rolling shaft 311 is gradually squeezed, and then the rolling shaft 311 is pressed against the grooves on the first supporting plate 21 and the second supporting plate 22. Then, during the upward movement of the load-bearing component, the rolling shaft 311 is gradually squeezed, and then the rolling shaft 311 gradually drives the locking and guide shaft 33 to move, and then the guide shaft 33 gradually slides along the limiting slide groove 1101, and then during the sliding, due to the limiting of the limiting slide groove 1101, the guide shaft 33 gradually moves in the direction away from the rotating plate 32, and then when moving away, it gradually drives the sliding plate 31 to move outward, so that the sliding plate 31 gradually extends and retracts outward. It can also lift up the collapsed objects on the load-bearing component. After the sliding plate 31 and the rotating plate 32 move to a certain position, the locking block 331 moves to the direction of the second locking groove 1103, and then under the elastic force of the second elastic member 3322, the locking block 331 is inserted into the second locking groove 1103, that is, the sliding plate 31 and the rotating plate 32 can be locked in this position, that is, the collapsed objects can be placed on the rotating plate 32 and the sliding plate 31, and restricted by the containing frame 12, and then the load-bearing component is moved down to the lowest position through the lifting device.

[0061] Specifically, it also includes a buffer locking assembly, which includes a third elastic member 1112 arranged in the limiting slide groove 1101, and one end of the third elastic member 1112 is provided with a buffer block 111, and the other end is fixedly arranged in the limiting slide groove 1101, and a first locking groove 1102 is also opened in the limiting slide groove 1101, and the first locking groove 1102 is adapted to the locking block 331, one end of the rolling shaft 311 is slidably arranged on the sliding plate 31, and a sliding rod 332 is slidably arranged in the rolling shaft 311 along the axial direction, and a guide column 332 is slidably arranged on the sliding rod 332, and the guide column 332 is plugged into the sliding plate 31. When the sliding plate 31 moves toward the rotating plate 32 in the extrusion inclined groove 3111 opened on the plate 31, the guide column 3321 can move along the extrusion inclined groove 3111, and then the sliding rod 332 can be driven to move toward the sliding plate 31, and then the locking block 331 can be driven to disengage from the first locking groove 1102. The outer sliding sleeve of the sliding rod 332 is connected to the sliding block 34, and the sliding block 34 is slidably connected to the sliding plate 31; and the first elastic member 3311 is sleeved on the sliding rod 332, and one end of the first elastic member 3311 abuts against the side wall of the locking block 331, and the other end abuts against the side wall of the guide shaft 33.

[0062] That is, the present invention provides a buffer locking assembly, which can cause the sliding plate 31 and the rotating plate 32 to rotate when the supporting mechanism is locked, and finally make the rolling shaft 311 rest on the buffer block 111, and then the falling sliding plate 31 can be buffered, and then during the buffering process, the locking block 331 is inserted into the first locking groove 1102, that is, the sliding plate 31 can be locked in this position, so that it is not urgent to buffer the sliding plate 31 and the rotating plate 32 when they move downward, and the buffered sliding plate 31 can also be locked, that is, the stability of the device can be greatly improved.

[0063] When the present invention is actually used, the trainee first moves to the lane position, then moves to the load-bearing component, then the load-bearing component is pressed and moves downward, and then drives the fixed block 411 to move downward, that is, drives the driving rod 41 to move downward, and then through the coordinated use of the hinged movable rod 44 and the transmission rod 441, the interference block 421 at one end of the hinged rod 42 can be inserted into the second locking groove 1103, that is, the locking block 331 in the second locking groove 1103 can be squeezed out, and when the locking block 331 is completely out of the second locking groove 1103, the sliding plate 31 is unlocked and rotates. During the rotation process, the rolling shaft 311 slides downward along the limiting chute 1101, that is, the collapsed property on the sliding plate 31 and the rotating plate 32 falls down accordingly, and in the process of moving downward along the limiting chute 1101, since the limiting chute 1101 is gradually opened from top to bottom in the direction close to the rotating plate 32, that is, the sliding plate 31 can gradually shrink into the rotating plate 32 during the downward movement, that is, it will not only reduce the obstruction to the falling of the collapsed object, but also greatly reduce the space occupied by the sliding object after rotating along the containing frame 12, and then the collapsed object falls, realizing the training of the trainee;When the lifting device 31 is lifted up, the lifting plate 31 is lifted and locked, and the lifting device 31 is in a state of being rotated and locked. The shaft 33 gradually slides along the limiting groove 1101, and then during the sliding, due to the limitation of the limiting groove 1101, the guide shaft 33 gradually moves in the direction away from the rotating plate 32, that is, the sliding plate 31 at this time gradually moves in the middle direction of the box load-bearing component, gradually driving the sliding plate 31 to move outward, so that the sliding plate 31 gradually extends and contracts outward. In the process of the sliding plate 31 gradually extending and contracting outward, the collapsed object on the load-bearing component can be lifted up, so that the collapsed object is gradually between the sliding plate 31 and the rotating plate 3 2, after the sliding plate 31 and the rotating plate 32 move up to a certain position, the locking block 331 moves toward the second locking groove 1103. Then, under the elastic force of the second elastic member 3322, the locking block 331 is inserted into the second locking groove 1103, thereby locking the sliding plate 31 and the rotating plate 32 in this position. In other words, the collapsed object can be placed on the rotating plate 32 and the sliding plate 31 and restrained by the containing frame 12. The load-bearing assembly then moves down to its lowest position via the lifting device.

[0064] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
