Description

Technical Field

[0001] The present invention relates to the field of emergency protection facilities, and in particular to an emergency protection shed and an emergency protection method. Background Art

[0002] Slope instability is one of the three major global geological hazards, often presenting significant challenges to construction projects. With the rapid development of highway and railway construction, the intensification of global climate change, and the increase in geological activity, rockfall disasters are becoming increasingly frequent in mountainous and canyon regions, particularly those with high seismic intensity. These hazards are characterized by their widespread distribution, sudden onset, and high frequency, posing a serious threat to transportation infrastructure such as railways and highways, as well as to human activities.

[0003] Rockfall shelters, as important safety and protection facilities, play a vital role in areas prone to rockfall disasters, such as mountainous areas, high slopes, and cliffs, where geological conditions are complex and rockfall disasters are common. The primary function of a rockfall shelter is to provide safety for personnel, vehicles, equipment, and infrastructure below. In areas with unstable geological conditions, the risk of rockfall is ever-present. If rocks fall, the shelter effectively intercepts and absorbs their impact, preventing them from directly impacting personnel, vehicles, and equipment below, thereby ensuring the safety of life and property. The installation of rockfall shelters can improve disaster prevention and mitigation capabilities and reduce disaster losses. When a disaster strikes, the shelter can quickly take effect, minimizing casualties and property losses, and providing strong support for subsequent rescue and recovery efforts. While traditional rockfall shelters have achieved significant results in disaster prevention and mitigation, in some sudden disasters or emergency response situations, they have a long construction period and are unable to meet the timely requirements for emergency protection. Furthermore, in situations where temporary protection is required, installing traditional shelters can waste resources. Failure to install a shelter can also threaten life and property safety and disrupt transportation.

[0004] In response to this type of problem, it is very necessary to invent an emergency protection measure that can quickly protect against disasters or potential threats. Summary of the Invention

[0005] The purpose of the present invention is to provide an emergency protection shed and an emergency protection method to solve the technical problems that traditional protection sheds have a long construction period and are difficult to disassemble and reuse.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] In a first aspect, the present invention discloses an emergency shelter for detachably mounting on a mobile vehicle;

[0008] The jacking mechanism includes a movable end that can rise or fall, and a base frame is installed on the movable end. A horizontal push protection frame and a lifting protection frame are fixed to the upper end of the base frame respectively. The jacking mechanism can vertically lift the base frame and drive the horizontal push protection frame and the lifting protection frame to rise vertically, so that a protective space is provided under the base frame, the horizontal push protection frame and the lifting protection frame.

[0009] The horizontal push protection frame includes a first sliding frame and a second sliding frame that are symmetrically arranged, and the first sliding frame and the second sliding frame extend horizontally respectively;

[0010] The outer peripheries of the first sliding frame, the second sliding frame and the lifting protection frame are detachably covered with shielding members, so that the protection space can be shielded to achieve a protection function;

[0011] In the initial state, the first sliding frame and the second sliding frame are located at the initial positions, the side surface of the first sliding frame abuts against the side surface of the second sliding frame, and the lifting protection frame is located below the first sliding frame and the second sliding frame;

[0012] In the working state, the first sliding frame and the second sliding frame can slide in opposite directions to the working position respectively. At this time, there is a gap between the first sliding frame and the second sliding frame that can accommodate the lifting protection frame. The lifting protection frame can be lifted into the gap, and the two sides of the lifting protection frame are respectively in contact with the side surfaces of the first sliding frame and the second sliding frame. The upper surface of the lifting protection frame is flush with the upper surfaces of the first sliding frame and the second sliding frame.

[0013] The working principle of this solution is: when temporary emergency protection is needed, the emergency protection shed is installed on the mobile carrier, and the mobile carrier is moved to the required location, the jacking mechanism is operated to jack up the basic frame, and the horizontal push protection frame is operated to push the first sliding frame and the second sliding frame horizontally to the working position, and then the lifting protection frame is lifted to the said interval, and the two sides of the lifting protection frame are respectively abutted against the side surfaces of the first sliding frame and the second sliding frame, and the upper surface of the lifting protection frame is flush with the upper surfaces of the first sliding frame and the second sliding frame. In the working state, the periphery of the first sliding frame, the second sliding frame and the lifting protection frame are detachably covered with a shielding member to protect the protection space under each frame. The emergency protection shed is shielded to form an emergency protection shed to realize the protection function, which is beneficial to protecting people or objects in the protection space and protecting personal and property safety; when emergency protection is no longer needed, the lifting protection frame is operated to descend, and then the first sliding frame and the second sliding frame are operated to slide toward each other to the initial position, and then the jacking mechanism is operated to fall back to realize the folding of the entire structure; if the emergency protection shed on the mobile carrier needs to be replaced or repaired, the jacking structure and each frame structure on the mobile carrier can be disassembled; the emergency protection shed of this scheme has a simple structure and flexible installation; it can use the mobile carrier to quickly reach the designated location, which is quick and time-saving, thereby achieving timely emergency protection function, and the recovery and disassembly operations are convenient, and it is suitable for multiple scenarios.

[0014] As a preferred embodiment of the shielding member, the shielding member is a shock-absorbing assembly, and the tops of the first sliding frame, the second sliding frame and the lifting protection frame are respectively detachably connected with a shock-absorbing assembly; the shock-absorbing assembly includes a protective steel plate, and the tops of the first sliding frame, the second sliding frame and the lifting protection frame are respectively detachably connected with a protective steel plate; when in working state, the first sliding frame, the second sliding frame and the lifting protection frame can respectively drive the corresponding installed shock-absorbing assemblies to move synchronously, and when the upper surface of the lifting protection frame is flush with the upper surfaces of the first sliding frame and the second sliding frame, the upper surfaces of the corresponding installed shock-absorbing assemblies are flush, and the side surfaces of adjacent shock-absorbing assemblies abut against each other.

[0015] The shock-absorbing components can cope with emergency protection scenarios similar to those under unstable slopes. Unstable slopes often have falling rocks. The shock-absorbing components can then have a shock-absorbing effect on hard objects falling on them, reduce the degree of damage to the emergency protection shed caused by falling objects, and improve the safety of people or objects in the protection space. When each shock-absorbing component is in working condition, it moves synchronously with the corresponding frame structure, and finally aligns with each other to form an overall structure. Adjacent shock-absorbing components abut against each other without gaps, which can better realize the protection function.

[0016] As a preferred embodiment of the shock absorbing assembly, the shock absorbing assembly includes a plurality of energy dissipation modules that can be assembled with each other, the energy dissipation module including a top plate, a plurality of energy dissipation springs fixed to the bottom surface of the top plate, each of the energy dissipation springs extending vertically, and the extended end is fixed to the upper surface of the protective steel plate; a plurality of dampers are also fixed to the bottom surface of the top plate, each of the dampers extending vertically, and the extended end is fixed to the upper surface of the protective steel plate; each damper is respectively arranged at the center of each energy dissipation spring, and the extension direction of each damper is the same as the extension direction of each energy dissipation spring.

[0017] The energy dissipation module can convert part of the kinetic energy of falling rocks into its elastic potential energy, thereby reducing the impact on the protective shed. The damper can protect the energy dissipation module from repeated vibrations, making the protective shed more stable and safe.

[0018] As one of the implementation methods of the jacking mechanism, the jacking mechanism adopts a scissor jack, which includes a fixed end and a movable end. The fixed end is used to be detachably connected to a mobile carrier, and a rotating motor is installed on the fixed end. The output end of the rotating motor is fixedly connected to the movable end. When the rotating motor rotates, it can drive the movable end to rise and fall vertically; the movable end includes a top channel steel, the top channel steel extends horizontally and laterally, and a top clamping slot is respectively provided at both ends of the top of the top channel steel, and the basic frame is correspondingly provided with a base layer longitudinal beam, the base layer longitudinal beam extends horizontally and laterally, and the two ends of the base layer longitudinal beam can be clamped in the corresponding top clamping slot.

[0019] The use of jacks can avoid dependence on cranes, which is quick and time-saving; clamping the foundation layer longitudinal beams into the top slots can prevent the protective shed from deflecting or sliding during jacking and other related processes. The clamping form can facilitate installation and is also conducive to the maintenance or replacement of the superstructure.

[0020] As one of the implementation methods of the basic frame, the basic layer longitudinal beams are symmetrically and parallelly arranged. The basic frame also includes two basic layer cross beams, and the two ends of each basic layer cross beam are fixedly connected to the two basic layer longitudinal beams to enhance the structural strength of the basic frame; the basic frame also includes two parallel push guide steels for guiding the horizontal lateral movement of the push protection frame; each push guide steel is fixed to one end in the same direction of the two basic layer longitudinal beams; each push guide steel is parallel to the basic layer cross beam fixed at the corresponding end and there is a gap between the two, and a push force block is provided in each gap, and the two ends of the push force block are fixedly connected to the push guide steel and the basic layer cross beam at the corresponding position.

[0021] The foundation frame can provide a basic framework for the emergency protection shed, and cooperate with the scissor jack to form a protective space under the foundation frame. At the same time, the foundation frame also provides a force point and carrier for the expansion and contraction and lifting of the push protection frame and the lifting protection frame.

[0022] As a preferred solution for the horizontal push protection frame, the horizontal push protection frame includes a horizontal push assembly, which is respectively arranged on the bottom surfaces of the two side frames of the first sliding frame and the second sliding frame; the horizontal push assembly includes a concave guide channel steel, the concave guide channel steel is sleeved on the outer periphery of the horizontal push guide steel, and the concave guide channel steel can slide on the outer periphery of the horizontal push guide steel; horizontal telescopic jacks are respectively fixed on both sides of the horizontal push force block, and the two horizontal telescopic jacks can be telescoped in opposite directions respectively; in this way, in the horizontal direction, the horizontal telescopic jacks can push the horizontal push force block to move horizontally toward the two ends of the beam, thereby expanding the horizontal push protection frame laterally; a horizontal push force plate is respectively fixed on the end of each horizontal telescopic jack away from the horizontal push force block, and the horizontal push force plates are respectively fixed on the end of the corresponding concave guide channel steel; in this way, when the horizontal telescopic jack pushes the horizontal push force plate horizontally in the horizontal direction, the concave guide channel steel is driven to slide along the horizontal push guide steel to both sides, thereby driving the first sliding frame and the second sliding frame to expand to both sides.

[0023] As a preferred solution for the emergency shelter, a plurality of evenly distributed beam-column connecting members are fixed below the edges of the first sliding frame and the second sliding frame, and each of the beam-column connecting members is rotatably connected to a vertical rotating support column;

[0024] In the initial state, each of the vertical rotation support columns extends horizontally;

[0025] When in working state, each of the vertically rotating support columns rotates out to extend vertically and can contact the ground;

[0026] A middle locking plate is fixed below the edges of the first sliding frame and the second sliding frame corresponding to each vertical rotation support column. In the initial state, the free end of each vertical rotation support column can be locked on the middle locking plate.

[0027] As one of the implementation methods of the lifting protection frame, the lifting protection frame includes a lifting force-bearing beam, a vertical force-bearing plate is fixed on the bottom surface of the middle part of the base layer beam corresponding to the position of the lifting force-bearing beam, and a vertical telescopic jack is fixed between the vertical force-bearing plate and the lifting force-bearing beam; in this way, the vertical telescopic jack lifts or lowers the lifting protection frame by being subjected to force on the basic frame, and in the vertical direction, the vertical telescopic jack lifts the lifting force-bearing beam, so that the lifting protection frame rises to a position flush with the horizontal push protection frame.

[0028] As a preferred solution for the emergency protective shed, it also includes a plurality of oblique support columns, and correspondingly, ear plates are provided on the outer sides of the horizontal beams of the push layer, and one end of each of the oblique support columns can be detachably connected to the corresponding ear plate; so as to enhance the performance of the protective shed against lateral impact; the other end of each of the oblique support columns is detachably connected to an oblique support column base plate, and the oblique support column base plate is used to be fixed to the ground, so that each of the oblique support columns can play a better supporting role; hooks are provided at both ends and the middle of each of the oblique support columns, and a rock-blocking net is hung on each of the hooks. In actual application, the rock-blocking net is hung on the side of falling rocks according to the actual situation on site to prevent lateral falling rocks from causing damage to people and property; horizontal and vertical support ropes are passed through the bottom of the rock-blocking net, the purpose of which is to strengthen the force of the rock-blocking net on the hooks and enhance the overall force-bearing performance of the rock-blocking net.

[0029] In a second aspect, the present invention further discloses an emergency protection method, which comprises constructing the emergency protection shed as described above in a target area to achieve emergency protection of the target area; the construction process of the emergency protection shed comprises the following steps:

[0035] S6. Reverse the motor so that the shelter is subjected to force from the road surface and retract the scissor jacks until they are fully closed, and then drive the mobile vehicle away from the emergency shelter;

[0036] S7. Connect one end of the oblique support column to the ear plate and the other end to the oblique support column base plate, and place the bottom surface of the oblique support column base plate 72 on the road surface;

[0054] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0056] The present invention can be applied to temporary emergency protection scenarios, solving the technical problems of traditional protective sheds, such as long construction period and difficulty in disassembly and reuse.

[0057] First, see Figure 1 , based on the technical problems solved above, the present invention discloses an emergency protection shed for detachably mounting on a mobile vehicle 1;

[0058] The jacking mechanism includes a movable end that can rise or fall, and a base frame is installed on the movable end. A horizontal push protection frame 4 and a lifting protection frame 5 are fixed to the upper end of the base frame respectively; the jacking mechanism can vertically lift the base frame and drive the horizontal push protection frame 4 and the lifting protection frame 5 to rise vertically, so that a protective space is provided under the base frame, the horizontal push protection frame 4 and the lifting protection frame 5;

[0059] The horizontal push protection frame 4 includes a first sliding frame and a second sliding frame that are symmetrically arranged, and the first sliding frame and the second sliding frame extend horizontally respectively;

[0060] The outer peripheries of the first sliding frame, the second sliding frame and the lifting protection frame 5 are detachably covered with shielding members, so that the protection space can be shielded to achieve a protection function;

[0061] In the initial state, the first sliding frame and the second sliding frame are in the initial position, the side surface of the first sliding frame abuts against the side surface of the second sliding frame, and the lifting protection frame 5 is located below the first sliding frame and the second sliding frame;

[0062] When in working state, the first sliding frame and the second sliding frame can slide in opposite directions to the working position respectively. At this time, there is a gap between the first sliding frame and the second sliding frame that can accommodate the lifting protection frame 5. The lifting protection frame 5 can be lifted into the gap, and the two sides of the lifting protection frame 5 are respectively abutted against the side surfaces of the first sliding frame and the second sliding frame, and the upper surface of the lifting protection frame 5 is flush with the upper surfaces of the first sliding frame and the second sliding frame.

[0063] The working principle of this solution is: when temporary emergency protection is needed, the emergency protection shed is installed on the mobile carrier 1, and the mobile carrier 1 is moved to the required location, the jacking mechanism is operated to jack up the basic frame, and the horizontal push protection frame 4 is operated to push the first sliding frame and the second sliding frame horizontally to the working position, and then the lifting protection frame 5 is lifted to the said interval, and the two sides of the lifting protection frame 5 are respectively abutted against the side surfaces of the first sliding frame and the second sliding frame, and the upper surface of the lifting protection frame 5 is flush with the upper surface of the first sliding frame and the second sliding frame. In the working state, the periphery of the first sliding frame, the second sliding frame and the lifting protection frame 5 are detachably covered with a shielding member to shield the protection space under each frame to form an emergency protection shed and realize the protection function, which is conducive to protecting people or objects in the protection space and protecting personal and property safety;

[0064] When emergency protection is no longer needed, the lifting protection frame 5 is operated to descend, and then the first sliding frame and the second sliding frame are operated to slide toward each other to the initial position, and then the jacking mechanism is operated to fall back to realize the folding of the entire structure;

[0065] If the emergency protection shed on the mobile vehicle 1 needs to be replaced or repaired, the jacking structure and each frame structure on the mobile vehicle 1 can be disassembled;

[0066] The emergency protection shed of this solution has a simple structure and flexible installation. It can quickly reach the designated location using a mobile carrier, which is quick and time-saving, thereby achieving timely emergency protection functions. It is also easy to recycle and disassemble, and is suitable for multiple scenarios.

[0067] As one of the implementation methods of the shielding member, the shielding member is one of waterproof cloth, windproof cloth, sunshade cloth, Oxford cloth, cardboard, plastic plate, iron plate, and steel plate. It is suitable for areas where there is no object falling from the top, and can provide simple protection for people and property inside the protective space, and can achieve protective functions such as sunshade, rainproof, windproof, and light-proof storage.

[0068] As a preferred option for the shield, please refer to Figures 3 to 5 ,as well as Figure 8 、 Figure 9 , the shielding member is a shock-absorbing assembly, and the tops of the first sliding frame, the second sliding frame and the lifting protection frame 5 are respectively detachably connected with a shock-absorbing assembly; the shock-absorbing assembly includes a protective steel plate 48, and the tops of the first sliding frame, the second sliding frame and the lifting protection frame 5 are respectively detachably connected with a protective steel plate 48; when in working state, the first sliding frame, the second sliding frame and the lifting protection frame 5 can respectively drive the corresponding installed shock-absorbing assemblies to move synchronously, and when the upper surface of the lifting protection frame 5 is flush with the upper surfaces of the first sliding frame and the second sliding frame, the upper surfaces of the corresponding installed shock-absorbing assemblies are flush, and the side surfaces of adjacent shock-absorbing assemblies abut against each other.

[0069] The shock-absorbing components can cope with emergency protection scenarios similar to those under unstable slopes. Unstable slopes often have falling rocks. The shock-absorbing components can then have a shock-absorbing effect on hard objects falling on them, reduce the degree of damage to the emergency protection shed caused by falling objects, and improve the safety of people or objects in the protection space. When each shock-absorbing component is in working condition, it moves synchronously with the corresponding frame structure, and finally aligns with each other to form an overall structure. Adjacent shock-absorbing components abut against each other without gaps, which can better realize the protection function.

[0070] As a preferred option for shock absorbing components, please refer to Figure 12 The shock absorbing assembly includes a plurality of energy dissipation modules 49 that can be assembled with each other, and the energy dissipation module 49 includes a top plate 491. A plurality of energy dissipation springs 492 are fixed to the bottom surface of the top plate 491, and each of the energy dissipation springs 492 extends vertically, and the extended end is fixed to the upper surface of the protective steel plate 48; a plurality of dampers 493 are also fixed to the bottom surface of the top plate 491, and each of the dampers 493 extends vertically, and the extended end is fixed to the upper surface of the protective steel plate 48; each damper 493 is respectively arranged at the center of each energy dissipation spring 492, and the extension direction of each damper 493 is the same as the extension direction of each energy dissipation spring 492.

[0071] The energy dissipation module 49 can convert part of the kinetic energy of falling rocks into the elastic potential energy of the energy dissipation module 49, thereby reducing the impact on the protective shed. The damper 493 can protect the energy dissipation module 49 from repeated vibrations, thereby making the protective shed more stable and safe.

[0072] The energy dissipation principle of the energy dissipation module is as follows: In this embodiment, a single energy dissipation module is regarded as a parallel model of four springs and one damper. Then, the calculation formula for the magnitude of the instantaneous force of the energy dissipation module is:

[0073] F = kx + cv

[0074] Where k is the spring stiffness; x is the spring displacement; c is the damping coefficient; and v is the instantaneous velocity of the object.

[0075] Then, the single spring stiffness k1 is:

[0076] k1= Gd 4 / 8 nD 3

[0077] Where G is the shear modulus of the spring material; d is the spring wire diameter; D is the spring outer diameter; and n is the number of spring coils.

[0078] A single energy dissipation module consists of four identical springs connected in parallel, so the total elastic stiffness k=4 The instantaneous force formula of the energy dissipation module is as follows:

[0079] k1= Gd 4 / 8 nD 3 + cv

[0080] Where x is the spring displacement; c is the damping coefficient; v is the instantaneous velocity of the object; G is the shear modulus of the spring material; d is the spring wire diameter; D is the spring outer diameter; and n is the number of spring coils.

[0081] As a material choice for the top plate 491 , the top plate 491 is made of plastic or steel.

[0082] As a method of joining the energy dissipation modules, the top plates 491 of the adjacent energy dissipation modules are joined together by bonding or welding.

[0083] As one of the embodiments of the energy dissipation module, each energy dissipation module includes 4 energy dissipation springs, 4 dampers and 1 top plate 491. One end of each energy dissipation spring is fixed to the lower surface of the top plate 491, and the other end is fixed to the upper surface of the protective steel plate. Each damper is respectively arranged at the center of each energy dissipation spring, and the extension direction of each damper is the same as the extension direction of each energy dissipation spring.

[0084] As one of the ways to realize the lifting mechanism, please refer to Figure 1 and Figure 10 The jacking mechanism adopts a scissor jack 3, which includes a fixed end 31 and a movable end. The fixed end 31 is used to be detachably connected to the mobile carrier 1. A rotating motor 32 is installed on the fixed end 31. The output end of the rotating motor 32 is fixedly connected to the movable end. When the rotating motor 32 rotates, it can drive the movable end to rise and fall vertically; the movable end includes a top channel steel 33, and the top channel steel 33 extends horizontally and laterally. A top card slot 34 is respectively provided at both ends of the top of the top channel steel 33, and the basic frame is correspondingly provided with a basic layer longitudinal beam 63. The basic layer longitudinal beam 63 extends horizontally and laterally, and the two ends of the basic layer longitudinal beam 63 can be snapped into the corresponding top card slot 34.

[0085] The use of a jack can avoid dependence on a crane, which is quick and time-saving; clamping the base layer longitudinal beam 63 into the top clamping slot 34 can prevent the protective shed from deflecting or sliding during jacking and other related processes. The clamping form can facilitate installation and is also conducive to the maintenance or replacement of the upper structure.

[0109] Each of the two ends and the middle of the oblique support column 7 is provided with a hook 71, and each of the hooks 71 is hung with a rock-blocking net 8. In actual application, the rock-blocking net 8 is hung on the side of the falling rock according to the actual situation on site to prevent the lateral falling rock from causing damage to people and property;

[0110] The bottom of the rock-blocking net 8 is connected with horizontal and vertical support ropes 81, the purpose of which is to strengthen the force exerted on the rock-blocking net 8 by the hooks and enhance the overall force-bearing performance of the rock-blocking net 8.

[0111] Specifically, one end of each of the oblique support columns 7 is respectively provided with an end connection hole 73 , and by inserting a locking pin into the end connection hole 73 and the ear plate 46 , each of the oblique support columns 7 can be detachably connected to the corresponding ear plate 46 .

[0112] As one example of a lifting protection frame, please refer to Figure 11 The lifting protection frame 5 includes a plurality of parallel lifting protection frame cross beams 512 and two parallel lifting protection frame longitudinal beams 513. Each lifting protection frame cross beam 512 is arranged between two lifting protection frame longitudinal beams 513, and the two ends of each lifting protection frame cross beam 512 are respectively fixed to the inner side surfaces of the two lifting protection frame longitudinal beams 513; at the same time, the two ends of the lifting force beam 511 are respectively fixed to the inner side surfaces of the two lifting protection frame longitudinal beams 513.

[0113] As a preferred solution for lifting protection frame, please refer to Figures 7 to 11 , a reinforcement beam is fixed at the bottom of the lifting protection frame beam 512 to reinforce the overall structure;

[0114] The reinforcement beam includes a steel beam 521, the top of the steel beam 521 is fixedly connected to the bottom of the lifting protection frame beam 512, and two transverse connecting members 522 are fixedly connected at both ends of the steel beam 521. Each transverse connecting member 522 is rotatably connected to a rotating beam 524 at both ends away from the steel beam 521.

[0115] In the initial state, the rotating beam 524 extends horizontally and longitudinally;

[0116] In the working state, the rotating beam 524 can rotate around the transverse connecting member 522 from a horizontal longitudinal position to a horizontal transverse position;

[0117] The two ends of the steel beam 521 are respectively provided with longitudinal locking plates 523, and locking holes are opened on the longitudinal locking plates 523. The rotating beam 524 is provided with a rotating beam locking hole 525. The locking holes on the longitudinal locking plates 523 can be connected with the rotating beam locking holes 525 through locking pins to lock the position of the rotating beam 524 so that it maintains a horizontal position.

[0118] For details, please refer to Figures 7 to 11A transverse connecting U-shaped groove 47 is also fixed under the horizontal push protection frame 4, and a transverse locking connection hole 471 is opened on the transverse connecting U-shaped groove 47. When the rotating beam 524 rotates to the horizontal position, the locking pin is used to pass through the rotating beam locking hole 525 and the transverse locking connection hole 471 to connect the transverse connecting U-shaped groove 47 and the rotating beam 524 into a whole, thereby increasing the integrity between the lifting protection frame 5 and the horizontal push protection frame 4, so that each protection layer is connected to form a solid whole.

[0119] Specifically, the oblique support column base plate 72 and the vertical support column base plate 434 are both provided with four anchor holes. A drill is used to drill holes at the anchor holes, and ground anchor bolts are installed to fix the protective shed to the bottom surface, thereby preventing the protective shed from shifting or tipping over due to impact.

[0120] Specifically, one implementation of the mobile vehicle is a panel truck capable of carrying large equipment.

[0121] Specifically, one of the structural forms of the locking pin 9 used in the above structure is as follows Figure 13 As shown, of course, other structures that can lock each hole can be adopted by the above-mentioned various schemes, not limited to Figure 13 The structural forms listed in .

[0122] The working principle of this solution is as follows: the mobile vehicle 1 provided by this solution can transport the protective shed to the designated location, the scissor jack 3 can lift the top of the protective shed to a predetermined height, the horizontal telescopic jack 66 pushes the push-type protective frame 4 to expand to both sides, and when expanded to a fixed width, the vertical telescopic jack 67 lifts the lifting protective frame 5 to be flush with the push-type protective frame 4, and then connects the rotating crossbeam 524 in the reinforcement crossbeam to the horizontal connecting U-shaped groove 47 and inserts the locking pin to form the three protective layers into a whole. After the above steps are completed, pull out the locking pin in the middle locking plate 45 to keep the four vertical rotating support columns 43 vertical, align the end locking hole 432 with the locking connection hole 442, and insert the locking pin through the hole. Slowly lower the scissor jack 3 so that the vertical rotating support column 43 is placed on the road surface and bears the force of the entire protective shed. The connecting hole 73 at one end of the oblique support column 7 is connected to the ear plate 46 via a locking pin, and the connecting hole 73 at the other end is connected to the oblique support column base plate 72 via a locking pin. Ground anchors are then drilled and installed through the anchor holes on the oblique support column base plate 72 and the vertical support column base plate 434 to secure the support columns of the protective shed to the ground. Each oblique support column 7 has three rows of hooks 71. The horizontal and vertical support ropes 81 of the corresponding size from the rock barrier 8 are hung on the hooks 71 at the appropriate positions. The mobile vehicle 1 is then driven away from the protective shed. The entire protective shed is now installed.

[0123] The bottom of the protective steel plate 48 is connected to the horizontal and vertical beams of the protective layer, and the energy dissipation modules 49 are evenly arranged in a rectangular shape on the top. Each energy dissipation module 49 is composed of 4 energy dissipation springs 492, 4 dampers 493 and 1 top plate 491. Each energy dissipation spring 492 contains a damper 493, one end of which is fixed to the protective steel plate 48, and the other end is fixed to the top plate 491. The above-mentioned energy dissipation module 49 can convert part of the kinetic energy of falling rocks into the potential energy of the energy dissipation module 49, thereby reducing the impact on the protective shed. The damper 493 can protect the energy dissipation module 49 from repeated vibrations, making the protective shed more stable and safe. The above-mentioned stone retaining net 8 is hung on the hook 71 on the oblique support column 7 through the horizontal and vertical support ropes 81. This is conducive to forming a force arrangement with the protective shed, expanding the force range, reducing local stress, and thus protecting personnel and others from damage caused by lateral falling rocks. The width of the above-mentioned device during transportation can be reduced by transporting it on a vehicle, reducing the transportation difficulties caused by the excessive width, and quickly reaching the designated location. The jacking effect of the scissor jack 3 is utilized to avoid dependence on a crane. The assembled installation method is quick and time-saving, thereby achieving the advantages of emergency protection, ensuring the safety of people and property, and quickly restoring traffic.

[0124] The construction process of the emergency protection shed is:

[0125] (1) Cleaning the road surface;

[0126] First, the road surface is cleaned. If there are fallen rocks or other obstacles on the road surface in the rockfall section, the road surface must be cleaned first so that the mobile vehicle 1 can reach the designated location smoothly.

[0127] (2) Transportation of protective shed

[0128] In disaster-stricken sections or sections requiring emergency protection, the protective shed and related equipment (such as rock-blocking nets, oblique support columns, etc.) are transported to the required sections via a mobile vehicle 1 panel truck.

[0129] (3) Placement of protective shed

[0130] Stop the mobile vehicle at a suitable position, start the horizontal telescopic jack 66 to expand the horizontal push protection frame 4 to both sides to the specified width and close the horizontal telescopic jack 66, then start the vertical telescopic jack 67 to lift the lifting protection frame 5 to be flush with the horizontal push protection frame 4 and close the vertical telescopic jack 67. At this time, the protective shed has been fully unfolded, and then pull out the locking pins at the corresponding holes of the longitudinal locking plate 523 and the rotating beam locking hole 525, rotate the rotating beam 524 from the longitudinal direction to the transverse direction and clamp it in the transverse connecting U-shaped groove 47, insert the locking pins at the corresponding holes of the transverse locking connection hole 471 and the rotating beam locking hole 525, so that the protective layer is connected into a whole to increase the protection performance. The locking pins at the corresponding positions of the middle locking plate 45 and the middle locking hole 433 are then removed, allowing the vertical rotation support column 43 to rotate about the rotation connection hole 441. The rotary motor 32 in the scissor jack 3 is then activated to raise the roof of the protective shed until the vertical rotation support column 43 is fully vertical. At this point, the locking pins are inserted into the corresponding positions of the locking connection hole 442 and the end locking hole 432, locking the vertical rotation support column 43 in the vertical direction. The rotary motor 32 is then reversed to apply force to the protective shed against the road surface and the scissor jack is retracted until it is fully closed. The mobile vehicle 1 is then driven away from the protective shed.

[0131] (4) Installation of oblique support columns and rock screens

[0132] Align the connecting hole 73 at one end of the oblique support column 7 with the corresponding hole on the ear plate and insert the locking pin. Connect the other end to the oblique support column base plate 72. Place the bottom surface of the oblique support column base plate 72 on the road surface. Complete the installation of all oblique support columns 7 in the same way. Then hang the stone barrier net 8 with the horizontal and vertical support ropes 81 on the hook 71. This will provide preliminary protection for the construction workers in the subsequent steps.

[0133] (5) Fixing the base plate of the support column

[0134] Four bolt holes are pre-set on the diagonal support column base plate 72 and the vertical support column base plate 434. Use a drill to drill holes into the road surface to the required depth at the bolt holes. Then install anchor expansion bolts to secure each support column to the road surface. This prevents the shelter from movement or tipping due to falling rocks. After completing these steps, the entire installation process is complete.

[0135] The disassembly process of the emergency protection shed is:

[0136] First, drive the mobile vehicle 1 under the protective shed, align the top card slot 34 of the scissor jack 3 with the longitudinal beam 63 of the foundation layer, lift the scissor jack 3 and clamp the top card slot on the longitudinal beam 63 of the foundation layer, so as to support the protective shed and ensure the safety of the demolition process; remove the bolts of the bottom plate of the support column, remove the stone retaining net 8, pull out the locking pin at the ear plate 46, thereby removing the oblique support column 7, pull out the locking pin on the locking connection hole 442 in the beam-column connecting member 44, rotate the vertical rotation support column 43 to the longitudinal direction, and lock it. Insert the stop pin into the hole of the middle locking plate 45, thereby fixing the vertical rotating support column 43 in the longitudinal direction; reverse the rotating motor 32 so that the protective layer slowly moves down to the slot pad 2 under the support of the scissor jack 3, pull out the locking pin at the transverse locking connection hole 471, rotate the rotating crossbeam 524 back to the longitudinal direction and insert the locking pin into the hole of the longitudinal locking plate 523, start the vertical telescopic jack 67 to lower the lifting protection frame 5 to the top surface of the concave guide channel steel 42, and start the horizontal telescopic jack 66 to retract the push protection frame 4 from both sides to the middle until they are close together. After completing the above steps, the disassembly of the entire protective shed is completed, and the protective shed is transported away from the site by the mobile carrier 1. When the rockfall section has been dealt with or the disaster risk has been eliminated, the protective shed can be recovered as a pre-planned emergency equipment.

The energy dissipation module and rock barrier of the present invention can effectively reduce the impact of falling rocks and reduce damage to the protection shed, thereby further ensuring traffic safety. The present invention has obvious temporary protection effects and can be reused, avoiding waste of resources and achieving the purpose of economy and convenience.

[0143] In a second aspect, the present invention further discloses an emergency protection method, which utilizes the above-mentioned emergency protection shed to be constructed in a target area to achieve emergency protection of the target area and enable rapid acquisition of emergency protection facilities. The construction process of the emergency protection shed includes the following steps:

[0144] S1. Clear the road and move the mobile vehicle carrying the emergency shelter to the designated location;

[0145] S2. Start the horizontal telescopic jack to expand the push protection frame to both sides to the specified width and close the horizontal telescopic jack;

[0146] S3. Start the vertical telescopic jack to lift the lifting protection frame to the same level as the horizontal push protection frame and close the vertical telescopic jack to fully deploy the emergency protection shed.

[0147] S4. Connect the lifting protection frame with the horizontal push protection frame, and rotate the vertical rotation support column in the vertical direction;

[0148] S5. Start the rotating motor in the scissor jack to continue lifting the emergency protection shed until the vertical rotating support column can be completely vertical, and then fix the vertical rotating support column in position;

[0149] S6. Reverse the motor so that the shelter is subjected to force from the road surface and retract the scissor jacks until they are fully closed, and then drive the mobile vehicle away from the emergency shelter;

[0150] S7. Connect one end of the oblique support column to the ear plate and the other end to the oblique support column base plate, and place the bottom surface of the oblique support column base plate 72 on the road surface;

[0151] S8. Connect the horizontal and vertical support ropes at the bottom of the rock retaining net and hang them on the hooks to complete the installation of the emergency protection shed.

[0152] Specifically, in steps S1 to S6, the mobile carrier is stopped at a suitable position, the horizontal telescopic jack 66 is started to expand the push protection frame 4 to both sides to the specified width and the horizontal telescopic jack 66 is closed, and then the vertical telescopic jack 67 is started to lift the lifting protection frame 5 to be flush with the push protection frame 4 and the vertical telescopic jack 67 is closed. At this time, the protective shed has been fully unfolded, and then the locking pins at the corresponding hole positions of the longitudinal locking plate 523 and the rotating beam locking hole 525 are pulled out, and the rotating beam 524 is rotated from the longitudinal direction to the transverse direction and stuck in the transverse connecting U-shaped groove 47, and the locking pins are inserted into the hole positions corresponding to the transverse locking connection hole 471 and the rotating beam locking hole 525 to connect the protective layer into a whole, thereby increasing the protective performance. The locking pins at the corresponding positions of the middle locking plate 45 and the middle locking hole 433 are then removed, allowing the vertical rotation support column 43 to rotate about the rotation connection hole 441. The rotary motor 32 in the scissor jack 3 is then activated to raise the roof of the protective shed until the vertical rotation support column 43 is fully vertical. At this point, the locking pins are inserted into the corresponding positions of the locking connection hole 442 and the end locking hole 432, locking the vertical rotation support column 43 in the vertical direction. The rotary motor 32 is then reversed to apply force to the protective shed against the road surface and the scissor jack is retracted until it is fully closed. The mobile vehicle 1 is then driven away from the protective shed.

[0153] Specifically, in step S7, the connecting hole 73 at one end of the oblique support column 7 is aligned with the corresponding hole on the ear plate and a locking pin is inserted to connect one end of the oblique support column to the ear plate.

[0154] Specifically, in step S7, four bolt holes are pre-set on both the diagonal support column base plate 72 and the vertical support column base plate 434. A drill is used to drill holes into the road surface at the bolt holes to the required depth, and anchor expansion bolts are installed to secure each support column to the road surface. This prevents the shelter from movement or overturning due to falling rocks. Upon completion of these steps, the entire installation process is complete.

[0155] After the emergency shelter is used, the disassembly process of the emergency shelter is as follows:

[0156] First, drive the mobile vehicle 1 under the protective shed, align the top card slot 34 of the scissor jack 3 with the longitudinal beam 63 of the foundation layer, lift the scissor jack 3 and clamp the top card slot on the longitudinal beam 63 of the foundation layer, so as to support the protective shed and ensure the safety of the demolition process; remove the bolts of the bottom plate of the support column, remove the stone retaining net 8, pull out the locking pin at the ear plate 46, thereby removing the oblique support column 7, pull out the locking pin on the locking connection hole 442 in the beam-column connecting member 44, rotate the vertical rotation support column 43 to the longitudinal direction, and lock it. Insert the stop pin into the hole of the middle locking plate 45, thereby fixing the vertical rotating support column 43 in the longitudinal direction; reverse the rotating motor 32 so that the protective layer slowly moves down to the slot pad 2 under the support of the scissor jack 3, pull out the locking pin at the transverse locking connection hole 471, rotate the rotating crossbeam 524 back to the longitudinal direction and insert the locking pin into the hole of the longitudinal locking plate 523, start the vertical telescopic jack 67 to lower the lifting protection frame 5 to the top surface of the concave guide channel steel 42, and start the horizontal telescopic jack 66 to retract the push protection frame 4 from both sides to the middle until they are close together. After completing the above steps, the disassembly of the entire protective shed is completed, and the protective shed is transported away from the site by the mobile carrier 1. When the rockfall section has been dealt with or the disaster risk has been eliminated, the protective shed can be recovered as a pre-planned emergency equipment.
