Description

Technical Field

[0001] This utility model relates to the field of coal mine safety technology, specifically to a comprehensive emergency rescue support device for coal mines. Background Technology

[0002] The comprehensive emergency rescue support device in a coal mine is a protective structure installed in the coal mine roadway to protect emergency rescue equipment. In the event of a roadway collapse, it can effectively protect the emergency rescue equipment and enable trapped personnel to access and use the equipment normally.

[0003] Currently, conventional emergency rescue integrated support devices are typically external box-type structures, meaning protective boxes are placed inside the tunnel to house emergency rescue equipment, protecting the equipment from damage by falling rocks. While these external box-type integrated support devices can protect emergency rescue equipment, in the event of a tunnel collapse or rockfall, there are situations where the protective box can be buried and cannot be opened. This means it's difficult to create an open area outside the protective box for operation, and even if nearby personnel manage to open the protective box in time, they may still be unprotected, making it difficult to guarantee the safety of those seeking refuge.

[0004] Therefore, existing integrated protection devices with external enclosures are difficult to provide shelter for refugees and easy-to-access emergency rescue equipment because they are easily buried. Utility Model Content

[0005] The purpose of this utility model is to provide a comprehensive emergency rescue support device for coal mines, so as to solve the technical problems in the prior art that the device itself is easily buried and cannot provide shelter for refugees, and that it is difficult to provide emergency rescue equipment that is easy to access.

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0007] A comprehensive emergency rescue support device for coal mines includes a bottom guard plate, on which two sets of bearing seats are symmetrically arranged, and each set of bearing seats is rotatably mounted with a side guard plate via a shaft. The side guard plates are vertically attached to the side wall of the coal mine roadway.

[0008] An upper guard plate is provided at the upper end of the two side guard plates. The two ends of the upper guard plate abut against the outer wall of the two side guard plates and are fastened by pin bolts. The upper guard plate is arched and fixed to the top wall of the tunnel.

[0009] The bottom of the bottom protective plate is provided with a storage room, and the bottom protective plate has a storage opening that connects to the storage room. The storage room is buried underground in the tunnel and the storage opening is sealed by a cover plate.

[0010] When the upper guard plate is pushed downwards due to the collapse of the tunnel, the upper guard plate and the side guard plate form a shearing force to cut the pin bolts, thereby unlocking the two side guard plates and squeezing the two side guard plates inward. After the two side guard plates are squeezed inward by the upper guard plate, they tilt down simultaneously and abut against each other to form a triangular safety area. The storage opening is located below the triangular safety area to protect the emergency rescue equipment stored in the storage room and provide a temporary protection zone.

[0011] As a preferred embodiment of this utility model, two limiting strips are symmetrically arranged on the bottom guard plate. After the side guard plate is tilted, the limiting strips support the side guard plate to maintain a fixed tilt angle.

[0012] As a preferred embodiment of this utility model, the upper guard plate includes an arched mesh frame, and multiple support ends are provided on both sides of the arched mesh frame, with each support end having a screw hole.

[0013] Multiple pin holes are provided on the upper side wall of the side guard plate, and the multiple pin holes are respectively aligned with the multiple screw holes on the same side;

[0014] The pin bolt is inserted into the pin hole, and its front end is screwed into the screw hole.

[0015] As a preferred embodiment of this utility model, the pin bolt includes a smooth section and a threaded section, the smooth section and the threaded section are coaxially connected, the smooth section is used to insert into the pin hole, and the threaded section is used to screw into the threaded hole.

[0016] In a preferred embodiment of this utility model, the junction of the smooth rod segment and the threaded segment is recessed inward to form a broken line, and the smooth rod segment and the threaded segment are rigidly connected.

[0017] As a preferred embodiment of this utility model, the support end is divided into a straight section and a wedge section, the straight section is abutted against the side guard plate, and the screw hole is formed in the straight section;

[0018] The wedge-shaped section connects to the straight section and faces the side guard plate, so that after the pin bolt is cut, the wedge-shaped section presses downward to drive the side guard plate to tilt inward.

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] This utility model adopts a method of constructing a safe zone for protection. By setting up a storage room at the bottom of the bottom protective plate, emergency rescue equipment is buried underground for protection. Furthermore, by setting up tiltable side protective plates on both sides of the bottom protective plate, and fixing the side protective plates to the upper protective plate with pins and bolts, the upper protective plate moves down to cut the pins and bolts and unlock the side protective plates in the event of a collapse. This allows the two side protective plates to tilt and abut against each other to form a triangular safe zone, providing a safe space for personnel to take shelter and retrieve emergency rescue equipment.

[0028] 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 protection scope of the present utility model.

[0029] like Figure 1As shown, this utility model provides a comprehensive emergency rescue support device in a coal mine, including a bottom guard plate 1. Two sets of bearing seats 11 are symmetrically arranged on the bottom guard plate 1, and a side guard plate 2 is rotatably installed on each set of bearing seats 11 via a shaft. The side guard plate 2 is vertically attached to the side wall of the coal mine roadway.

[0030] An upper guard plate 3 is provided at the upper end of the two side guard plates 2. The two ends of the upper guard plate 3 abut against the outer wall of the two side guard plates 2 and are connected and fastened by pin bolts 4. The upper guard plate 3 is arched and fixed to the top wall of the roadway.

[0031] Among them, a storage room 12 is provided at the bottom of the bottom protective plate 1, and the bottom protective plate 1 has a storage opening 121 that connects to the storage room 12. The storage room 12 is buried underground in the tunnel and the storage opening 121 is sealed by a cover plate.

[0032] When the upper guard plate 3 is pushed downward due to the collapse of the tunnel, the upper guard plate 3 and the side guard plate 2 form a shearing force to cut the pin bolts 4, thereby unlocking the two side guard plates 2 and squeezing the two side guard plates 2 inward. After the two side guard plates 2 are squeezed inward by the upper guard plate 3, they tilt down simultaneously and abut against each other to form a triangular safety area. The storage opening 121 is located below the triangular safety area to protect the emergency rescue equipment stored in the storage room 12 and provide a temporary protection zone.

[0033] The comprehensive emergency rescue support device of this utility model mainly consists of a storage chamber 12 for storing emergency rescue equipment located below the bottom protective plate 1, buried underground. Side protective plates 2 are installed on both sides of the bottom protective plate 1, attached to the side walls of the tunnel. Upper protective plates 3 are installed on the two side protective plates 2 and mounted on the top wall of the tunnel. In the event of a tunnel collapse, the upper protective plates 3 can delay the collapse of the tunnel top and, under pressure, press down to cut the pins and bolts 4 connecting the upper protective plates 3 and the side protective plates 2. This causes the side protective plates 2 to unlock and tilt inward. The two side protective plates 2 tilt inward and abut against each other to form a triangular safety area, which can protect the emergency rescue equipment in the storage chamber 12 from damage and also provide personnel shelter and operational space.

[0034] Compared to existing emergency rescue integrated support devices that use external box-type structures, the emergency rescue integrated support device of this utility model adopts a method of constructing a safe zone for protection. By setting a storage room 12 at the bottom of the bottom protective plate 1 and burying it underground, and setting two side protective plates 2 on the bottom protective plate 1, and setting an upper protective plate 3 on the two side protective plates 2 in a coordinated manner, when the upper protective plate 3 is subjected to collapse pressure, the pin bolts 4 connecting the side protective plates 2 and the upper protective plate 3 are cut, so that the two side protective plates 2 automatically tilt inward and abut against each other to form a triangular safe zone, thereby providing shelter space and protecting the emergency rescue equipment in the storage room 12, so that the sheltered personnel can easily access the emergency rescue equipment.

[0035] Of course, to avoid the two side guards tilting unevenly, such as Figure 1As shown, two limiting strips 13 are symmetrically arranged on the bottom guard plate 1. After the side guard plate 2 is tilted, the limiting strips 13 support the side guard plate 2 to maintain a fixed tilt angle.

[0036] Specifically, the angle of the side guard plate 2 after it is tilted is fixed by the limiting strip 13. That is, the two side guard plates 2 can be tilted one after the other to ensure that they abut against each other to form a triangular safety area, thereby effectively improving safety.

[0037] Since the upper guard plate 3 is installed at the top of the roadway, in order to avoid its weight affecting the stability of the roadway top, such as Figure 1 , Figure 2 As shown, the upper guard plate 3 includes an arched grid 31, and multiple supports 32 are provided on both sides of the arched grid 31. Each support 32 is provided with a screw hole 321.

[0038] Multiple pin holes 21 are provided on the upper side wall of the side guard plate 2, and the multiple pin holes 21 are respectively aligned with multiple screw holes 321 on the same side.

[0039] The pin bolt 4 is inserted into the pin hole 21, and its front end is screwed into the screw hole 321. The pin bolt 4 includes a smooth section 41 and a threaded section 42. The smooth section 41 and the threaded section 42 are coaxially connected. The smooth section 41 is used to insert into the pin hole 21, and the threaded section 42 is used to screw into the screw hole 321.

[0040] Specifically, the main body of the upper guard plate 3 is composed of an arched grid 31, which makes the upper guard plate 3 lightweight. The arched grid 31 abuts against the side guard plate 2 through multiple supports 32. After the supports 32 are fixed to the side guard plate 2 by pins and bolts 4, the two side guard plates 2 can be prevented from tilting inward, thus improving safety.

[0041] After the pin bolt 4 is inserted into the pin hole 21, it is locked through the screw hole 321, that is, the support end 32 is fastened to the outer wall of the side guard plate 2. Therefore, in the event of a collapse, the section of the pin bolt 4 located in the screw hole 321 is cut off by the support end 32, that is, the threaded section 42 is cut off.

[0042] Of course, in order to cut off the connection faster and improve the response speed, such as Figure 2 As shown, the junction of the smooth rod section 41 and the threaded section 42 is recessed inward to form a break line 43, and the smooth rod section 41 and the threaded section 42 are rigidly connected.

[0043] Specifically, a break line is set at the junction of the smooth rod section 41 and the threaded section 42 to reduce its radial load-bearing capacity, and the smooth rod section 41 and the threaded section 42 are rigidly connected, thereby achieving rapid cutting.

[0044] Of course, in order to allow the side guard plate 2 to tilt quickly and prevent falling rocks from prematurely entering the triangular safety area that will soon be formed, such as Figure 2As shown, the support end 32 is divided into a straight section 322 and a wedge section 323. The straight section 322 is installed close to the side guard plate 2, and the screw hole 321 is formed in the straight section 322.

[0045] The wedge section 323 is connected to the straight section 322, and the wedge section 323 faces the side guard plate 2, so that after the pin bolt 4 is cut off, the wedge section 323 presses downward to drive the side guard plate 2 to tilt inward.

[0046] Specifically, the straight section 322 is installed close to the side guard plate 2, which has little impact on the installation of the side guard plate 2 close to the roadway side wall. However, after the pin bolt 4 is cut off, the wedge section 323 moves downward, causing the side guard plate 2 to be subjected to inward pressure, thereby causing the side guard plate 2 to quickly tilt and form a triangular safety area.

[0047] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
