Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of rescue equipment, and specifically to a rescue device for tunnel collapses in narrow spaces. Background Art
[0002] Tunnel rescue equipment is the weapon for rescuers to fight. Whether the rescue equipment is good or bad usually plays a decisive role in the success or failure of rescue operations. Scientific and reasonable allocation of rescue equipment can make rescue operations achieve twice the result with half the effort. Studying foreign urban search and rescue teams, they have gradually developed from professional rescues such as geological disasters and firefighting. What we usually call tunnel rescue equipment refers to some tools or facilities that must be used during tunnel rescue operations after a tunnel accident, such as cranes, medical equipment, etc. These are all essential things during tunnel rescue, which can minimize casualties and property losses.
[0003] A Chinese patent with application number 201720688166.6 discloses a tunnel rescue device. The tunnel rescue device includes: a protective cylinder, which includes a connecting plate, an arc-shaped protective plate, and a support plate. The two arc-shaped protective plates are symmetrically hinged on both sides of the connecting plate. After the two support plates are hinged, they are then hinged to the two arc-shaped protective plates to form a cylindrical structure for the protective cylinder. A positioning track is provided on each support plate; a fixed stretcher with rollers at the bottom, and the rollers are adapted to the positioning track; and a detection and alarm device provided on the protective cylinder.
[0004] The above solution has a reasonable structural design and is convenient to use. It can effectively avoid and prevent secondary injuries to the injured during tunnel rescue. The protective cylinder can be used to form a protective shell for the fixed stretcher, and at the same time, the detection and alarm device can be used to prevent operation errors during rescue. However, the above solution has certain deficiencies in actual use. Through the enclosure of the protective cylinder, the protective cylinder can withstand collisions and frictions and can effectively protect the injured from secondary injuries. However, when the protective cylinder accidentally touches the wall inside the tunnel, although the protective cylinder can protect the injured, there will still be a strong sense of shock, which may cause harm to the body of the injured and cannot effectively buffer during contact, having certain deficiencies. Therefore, we provide a rescue device for tunnel collapses in narrow spaces to solve the above problems. Summary of the Invention
[0005] The purpose of the present invention is to make up for the deficiencies of the prior art and provide a rescue device for tunnel collapses in narrow spaces.
[0006] To achieve the above object, the present invention provides the following technical solution: A rescue device for tunnel collapse in a narrow space, including a placement bottom plate. A moving mechanism is provided below the placement bottom plate. A placement bed is fixedly installed above the placement bottom plate. A dragging handle is fixedly connected to each of the left and right sides of the placement bottom plate. A hydraulic lifting rod is installed above the placement bottom plate. An arc-shaped protective plate is installed above the hydraulic lifting rod. A set of buffer mechanisms are provided on each of the front and rear sides of the placement bottom plate. A buffer plate is provided on each of the front and rear sides of the placement bottom plate.
[0007] Preferably, the buffer mechanism includes a receiving cylinder. The outer surface of the receiving cylinder is fixedly connected to the outer surface of the placement bottom plate. A limiting groove is formed on the outer surface of the receiving cylinder.
[0008] Preferably, a limiting column is slidably connected to the inner wall of the receiving cylinder. The outer surface of the limiting column is fixedly connected to the outer surface of the buffer plate.
[0009] Preferably, a limiting piece is fixedly connected to the outer surface of the limiting column. The limiting piece is slidably connected to the limiting groove. An elastic member is sleeved on the outer surface of the receiving cylinder.
[0010] Preferably, one end of the elastic member is fixedly connected to the outer surface of the placement bottom plate, and the end of the elastic member away from the placement bottom plate is fixedly connected to the outer surface of the buffer plate.
[0011] Preferably, the moving mechanism includes a wheel frame and wheels. The upper surface of the wheel frame is fixedly connected to the bottom surface of the placement bottom plate. The wheels are installed inside the wheel frame.
[0012] Beneficial effects:
[0013] Compared with the prior art, the rescue device for tunnel collapse in a narrow space has the following beneficial effects:
[0014] First, by setting the moving mechanism, the movement of the entire rescue device can be facilitated. By setting the hydraulic lifting rod, the height of the arc-shaped protective plate can be adjusted, so that the arc-shaped protective plate can be conveniently stored, and thus the device can be conveniently carried. By setting the buffer mechanism and the buffer plate, when the buffer plate touches the inner wall of the tunnel, the impact force between the buffer plate and the tunnel can be effectively buffered, so as to effectively protect the injured personnel.
[0015] Second, by pushing the limiting column, the limiting piece can be driven to slide in the limiting groove, so as to achieve the limiting effect on the limiting piece and the limiting column. By squeezing the elastic member, the elastic member can generate elastic force, so as to buffer and relieve the impact force of squeezing the elastic member. Description of the drawings

[0021] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.
[0022] See Figures 1 to 4 , a rescue device for tunnel collapse in a narrow space, including a placing bottom plate 1, a moving mechanism 2 is provided below the placing bottom plate 1, a placing bed 3 is fixedly installed above the placing bottom plate 1, a dragging handle 4 is fixedly connected to both the left and right sides of the placing bottom plate 1, a hydraulic lifting rod 5 is installed above the placing bottom plate 1, an arc-shaped protection plate 6 is installed above the hydraulic lifting rod 5, a set of buffer mechanisms 7 are provided on both the front and rear sides of the placing bottom plate 1, and a buffer plate 8 is provided on both the front and rear sides of the placing bottom plate 1.
[0023] Here, a protective cover is wrapped around the periphery of the placing bed 3, which can effectively isolate falling dust and other debris; the dragging handle 4 can be bound to the trailer hitch, so as to facilitate the transportation of the device to a long-distance location; the arc-shaped protection plate 6 is made of stainless steel metal material, which can effectively protect against falling debris; two sets of buffer mechanisms 7 are provided, one set is provided on each of the front and rear sides of the placing bottom plate 1; two buffer plates 8 are provided, and one is provided on one side of each set of buffer mechanisms 7.
[0024] The entire device can be moved through the moving mechanism 2, and then the height of the arc-shaped protection plate 6 can be adjusted through the hydraulic lifting rod 5. After the device is moved to a suitable position, the injured person is lifted onto the placing bed 3, and then the device can be pulled through the dragging handle 4. During the moving process, if there is debris falling, it can be effectively blocked by the arc-shaped protection plate 6, which can effectively protect the injured person on the placing bed 3.
[0025] The buffer mechanism 7 includes a receiving cylinder 701. The outer surface of the receiving cylinder 701 is fixedly connected to the outer surface of the placement base plate 1, and a limiting groove 702 is formed on the outer surface of the receiving cylinder 701.
[0026] Here, the limiting groove 702 can limit the limiting piece 704.
[0027] A limiting post 703 is slidably connected to the inner wall of the receiving cylinder 701, and the outer surface of the limiting post 703 is fixedly connected to the outer surface of the buffer plate 8.
[0028] A limiting piece 704 is fixedly connected to the outer surface of the limiting post 703. The limiting piece 704 is slidably connected to the limiting groove 702, and an elastic member 705 is sleeved on the outer surface of the receiving cylinder 701.
[0029] Here, the elastic member 705 is made of a spring and has elastic telescopic resilience.
[0030] One end of the elastic member 705 is fixedly connected to the outer surface of the placement base plate 1, and the end of the elastic member 705 away from the placement base plate 1 is fixedly connected to the outer surface of the buffer plate 8.
[0031] By pushing the limiting post 703, the limiting piece 704 can be driven to slide in the limiting groove 702, so as to realize the limiting effect on the limiting piece 704 and the limiting post 703. By squeezing the elastic member 705, the elastic member 705 can generate elastic force, so as to buffer and relieve the impact force squeezing the elastic member 705.
[0032] The moving mechanism 2 includes a wheel frame 201 and wheels 202. The upper surface of the wheel frame 201 is fixedly connected to the bottom surface of the placement base plate 1, and the wheels 202 are installed inside the wheel frame 201.
[0033] Working principle: When the present invention is in use, the entire device can be moved through the moving mechanism 2, and then the height of the arc-shaped protection plate 6 can be adjusted by the hydraulic lifting rod 5. After the device is moved to a suitable position, the injured person is lifted onto the placement bed 3, and then the device can be pulled by dragging the handle 4. If debris falls during the movement, it can be effectively blocked by the arc-shaped protection plate 6, and the injured person on the placement bed 3 can be effectively protected. When the buffer plate 8 touches the tunnel wall or other debris during the movement, the buffer plate 8 will squeeze the limiting post 703 and the elastic member 705. At this time, the limiting post 703 will drive the limiting piece 704 to slide in the limiting groove 702, and at the same time the elastic member 705 will be compressed to generate elasticity, so as to relieve the impact force of the buffer plate 8, and further reduce the vibration of the placement bed 3, so as to effectively protect the injured person.
