Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically an emergency escape device for tunnel construction. Background Technology

[0002] Tunnel construction is a complex project that encompasses a series of stages from preliminary geological exploration and design planning to specific construction. It requires comprehensive consideration of various factors to ensure construction safety and project quality. Different excavation methods, such as drill-and-blast method and shield tunneling method, are often used during the construction process.

[0003] Tunnel construction has always been a high-risk operation area with many unpredictable factors. When a collapse occurs behind the tunnel face, it can be very dangerous for construction workers to be trapped inside.

[0004] When a collapse occurs during existing tunnel construction, construction workers need to move closer to a corner to avoid falling rocks. However, after avoiding the falling rocks, it is difficult for them to save themselves using their own abilities, resulting in them being trapped for a long time and increasing their own risk.

[0005] Therefore, an emergency escape device for tunnel construction is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: An emergency escape device for tunnel construction, comprising a base plate, a side plate fixedly connected to the top of the base plate, a top plate fixedly connected to the top of the side plate, the top plate being inclined, a connecting plate fixedly connected to the side wall of the base plate, the surface of the connecting plate being inclined, a rescue box installed on the surface of the base plate, an escape pipe connected to the side wall of the side plate, and a guide arrow fixedly connected to the middle of the side plate. By inclinedly setting the top plate, rocks can be guided when a collapse occurs, causing them to move along the surface of the top plate and quickly roll to the opposite side of the base plate, thereby reducing the number of rocks remaining on the top of the top plate. Simultaneously, the connecting plate can intercept rocks that come into contact with it, causing them to move along the surface, thus reducing the number of rocks entering the base plate. Furthermore, the guide arrow provides clear guidance when escapees enter, thereby accelerating the escape speed.

[0008] Preferably, a magnet is fixedly connected inside the side plate; the magnet is located at the edge of the escape pipe; a flashlight is provided on the surface of the magnet; a button is provided on the surface of the flashlight; by adding a magnet, the flashlight can be placed more conveniently, and the flashlight can be quickly attracted by the magnet's magnetism. At the same time, the flashlight is located next to the escape pipe, and the right hand can easily pick up the flashlight when escaping.

[0009] Preferably, a pair of fixing rods are fixedly connected to the side wall of the side plate; a warning light is provided at the end of the fixing rod; a switch is installed on the surface of the side plate; the switch is located below the magnet; by adding a warning light, the personnel who reach the bottom plate first in case of danger can turn on the warning light, thereby providing light and sound guidance for subsequent escape personnel.

[0010] Preferably, a warning tape is fixed to the surface of the escape tunnel; the surface of the warning tape is yellow; by adding the warning tape, the bright color of the warning tape can improve the observation and judgment of the escapers when searching for the escape tunnel, thereby increasing the accuracy of finding the escape tunnel.

[0011] Preferably, the escape pipe is internally reinforced with reinforcing ribs; the reinforcing ribs and the escape pipe are correspondingly arranged; by adding reinforcing ribs, the interior of the escape pipe can be reinforced so that when it is impacted, the force is distributed through the reinforcing ribs, thereby accelerating the force to eliminate the impact and reducing the deformation of the escape pipe under stress.

[0012] Preferably, a hook is fixed to the surface of the side plate; the hook is oriented towards the side closer to the escape tunnel; by adding a hook, the strap of the dust mask can be slipped onto the hook surface during maintenance, and then the strap can be detached from the hook surface by pulling the dust mask during emergency use, thereby speeding up the removal.

[0013] The advantages of this utility model are:

[0014] 1. The present invention provides an emergency escape device for tunnel construction. By tilting the top plate, it can guide rocks in the event of a collapse, causing them to move along the surface of the top plate and roll quickly to the opposite side of the bottom plate, thereby reducing the number of rocks stuck at the top of the top plate. At the same time, the connecting plate can intercept the rocks it comes into contact with, causing them to move along the surface, thereby reducing the number of rocks entering the bottom plate. In addition, the guide arrows provide clear guidance when escapees enter, thereby accelerating the escape speed of the escapees.

The emergency escape device for tunnel construction described in this utility model uses the magnet to quickly attract a flashlight, and the flashlight is located next to the escape pipe, so that the right hand can easily pick up the flashlight during the escape.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, an emergency escape device for tunnel construction includes a base plate 1, with a side plate 11 fixedly connected to the top of the base plate 1; a top plate 12 fixedly connected to the top of the side plate 11; the top plate 12 is inclined; a connecting plate 13 is fixedly connected to the side wall of the base plate 1; the surface of the connecting plate 13 is inclined; a rescue box 14 is installed on the surface of the base plate 1; an escape pipe 15 is connected to the side wall of the side plate 11; and a guide arrow 16 is fixedly connected to the middle of the side plate 11. During operation, the base plate 1 is first moved to the desired location to create a safe room, and then the escape pipe 15 is connected to the safe location. Subsequently, in the event of a dangerous collapse, construction workers can enter the base plate 1 to escape, at which point the rescue box 14 can be opened to retrieve the rescue equipment inside. The tools are retrieved to assist escapees. Upon entering the bottom slab 1, guide arrow 16 will immediately be visible, guiding escapees to the location of escape tunnel 15 without much observation. By tilting the top slab 12, rocks can be guided during a collapse, causing them to move along its surface and roll quickly to the opposite side of the bottom slab 1, thus reducing the number of rocks stuck on the top of the top slab 12. Simultaneously, the connecting plate 13 can intercept rocks it encounters, causing them to move along its surface, further reducing the number of rocks entering the bottom slab 1. Furthermore, the guide arrow 16 provides clear guidance as escapees enter, thereby accelerating their escape.

[0026] like Figures 2 to 5 As shown, a magnet 2 is fixedly connected inside the side plate 11; the magnet 2 is located at the edge of the escape pipe 15; a flashlight 21 is provided on the surface of the magnet 2; a button 22 is provided on the surface of the flashlight 21; when in operation, after the escapee enters, they can hold the flashlight 21 while moving towards the escape pipe 15 and then pull the flashlight 21 away from the magnet 2, thereby detaching it from the surface of the magnet 2. Then, when moving, the button 22 can be turned on to light up the flashlight 21, increasing its visibility during escape; by adding the magnet 2, the flashlight 21 can be placed more conveniently, and the flashlight 21 can be quickly attracted by the magnet 2. At the same time, the flashlight 21 is located next to the escape pipe 15, and the right hand can easily pick up the flashlight 21 during escape.

[0027] like Figures 1 to 2As shown, a pair of fixing rods 3 are fixedly connected to the side wall of the side plate 11; a warning light 31 is provided at the end of the fixing rod 3; a switch 32 is installed on the surface of the side plate 11; the switch 32 is located below the magnet 2; when in operation, after the escape personnel take the flashlight 21, they can press the switch 32 to turn on the warning light 31, and then emit light and alarm sound, thereby providing guidance for the construction personnel who escape later; by adding the warning light 31, the personnel who reach the bottom plate 1 first in case of danger can turn on the warning light 31, thereby providing light and sound guidance for the subsequent escape personnel.

[0028] like Figures 1 to 4 As shown, a warning tape 4 is fixed to the surface of the escape pipe 15; the surface of the warning tape 4 is yellow; during operation, when installing the escape pipe 15, the warning tape 4 is wrapped around the surface of the escape pipe 15, which can enhance the visibility of the escape pipe 15 by the color of the warning tape 4 when the escapers move, thus making the observation of the escape pipe 15 more accurate when moving; by adding the warning tape 4, the bright color of the warning tape 4 can improve the observation and judgment of the escapers when searching for the escape pipe 15, thereby increasing the accuracy of finding the escape pipe 15.

[0029] like Figure 4 As shown, a reinforcing rib 5 is fixedly connected inside the escape pipe 15; the reinforcing rib 5 and the escape pipe 15 are correspondingly arranged; during operation, when the tunnel collapses, solid materials will fall and come into contact with the escape pipe 15, thus impacting it. When an impact occurs, the reinforcing rib 5 increases the external support of the escape pipe 15, so that when it comes into contact with solid materials, the reinforcing rib 5 supports it and quickly disperses the impact vibration received; by adding the reinforcing rib 5, the interior of the escape pipe 15 can be reinforced, so that when it is impacted, the reinforcing rib 5 disperses the force and accelerates the force to eliminate the impact, thereby reducing the stress deformation of the escape pipe 15.

[0030] like Figure 5 As shown, a hook 6 is fixedly attached to the surface of the side plate 11; the hook 6 is oriented towards the side closer to the escape pipe 15; during operation, when performing routine maintenance on the side plate 11, the strap of the dust mask can be placed on the surface of the hook 6 so that it is fitted onto the hook 6. Then, when the construction personnel use it, when the dust mask is pulled towards the escape pipe 15, the strap of the dust mask will slide along the surface of the hook 6 and then detach through the end of the hook 6, allowing it to be quickly removed; by adding the hook 6, the strap of the dust mask can be fitted onto the surface of the hook 6 during maintenance, and then, when used in an emergency, the strap can be detached through the surface of the hook 6 by pulling the dust mask, thereby speeding up the removal.

[0031] Working principle: First, the base plate 1 is moved to the location where the safe house needs to be set up, and then the escape pipe 15 is connected to the safe location. In the event of a dangerous collapse, construction workers can enter the base plate 1 to escape. At this time, the rescue box 14 can be opened to retrieve the rescue tools inside, which will help the escapers escape. Upon entering the base plate 1, guide arrows 16 will be immediately visible, guiding the escapers to the location of the escape pipe 15 without much observation. After entering, the escapers can hold the flashlight 21 while moving towards the escape pipe 15, pulling the flashlight 21 away from the magnet 2's attraction, thus detaching it from the magnet's surface. Then, while moving, the button 22 can be turned on to illuminate the flashlight 21, increasing its visibility during escape. After retrieving the flashlight 21, the escapers can press the switch 32 to activate the warning light. 31 is activated, followed by lights and alarm sounds, thus guiding construction workers escaping from behind; when installing the escape pipe 15, warning tape 4 is wrapped around the surface of the escape pipe 15, and the color of the warning tape 4 can enhance the visibility of the escape pipe 15 as escapers move, making observation of the escape pipe 15 more accurate; when the tunnel collapses, solid materials will fall and come into contact with the escape pipe 15, causing impact. When impact occurs, the reinforcing ribs 5 increase the external support of the escape pipe 15, supporting it when in contact with solid materials and quickly dispersing the impact and shaking received; during routine maintenance of the side panel 11, the dust mask strap can be placed on the surface of the hook 6 and fitted onto the hook 6. When construction workers use it, as the dust mask is pulled towards the escape pipe 15, the dust mask strap will slide along the surface of the hook 6 and then detach from the end of the hook 6, allowing for quick removal.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
