Description

Technical Field

[0001] The invention relates to the technical field of rescue equipment, in particular to a multifunctional road rescue paving device. Background Art

[0002] Various geological disasters are serious and widespread.

[0003] Combined with the actual situation during natural disaster rescue, in the process of transporting rescue equipment to the disaster site, different complex road conditions will be faced: such as earthquakes in mountainous areas, landslides in mountainous areas, mudslides, etc., which cause the roads to be completely blocked or even completely damaged. The roads are difficult to continue to be open to traffic for a while, which puts great pressure on rescue. Combined with other situations, such as: bridge ruptures, mountain tunnel collapses, urban fires, mine collapses, and explosions of dangerous chemicals, these accidents often occur in urban roads or even densely populated areas. Due to the great randomness of the occurrence of accidents, it is difficult to open and evacuate the rescue roads in the first place, which leads to the rapid deployment of rescue and disaster relief, and it is urgent to quickly open or build temporary rescue roads.

[0004] Traditional road rescue equipment mostly assists rescue personnel in road rescue construction, such as the motorized transportation of road construction materials. However, road rescue equipment itself does not have the ability to build roads, and often requires manpower to build construction materials to form rescue roads. During this period, relying on manpower to build rescue roads will greatly limit the speed. For example, in rescue scenarios after natural disasters (such as earthquakes, mudslides, etc.), time is life. Manual handling and laying of construction materials, such as stones and wood, is much less efficient than mechanized equipment. In addition, human physical strength is limited, and efficiency will be further reduced after long-term work. At the same time, building rescue roads requires precise operations. Work such as laying wooden boards to form simple bridges or stacking stones to fill potholes on the road requires a lot of time to ensure its stability and safety. For example, in mountain road rescue, sandbags are manually carried to reinforce the road slopes. The placement and stacking method of each bag of sandbags need to be carefully considered, which greatly increases the time for road repair.

[0005] Therefore, based on the problems existing in the above-mentioned road rescue equipment, a multifunctional road rescue paving device is proposed to solve them. Summary of the invention

[0016] Furthermore, two polished rods are installed on the upper and lower outer walls of the base, and a second linear motor is installed through the support of the polished rods. The ends of the two second linear motors are arranged opposite to each other and are respectively connected to one of the slide rails.

[0018] Furthermore, two sets of movable tracks are installed on both sides of the road rescue vehicle carrier; the four sets of movable tracks are arranged in a triangular track structure, and a plurality of pin rings are protrudingly provided on both sides of the road steel plate.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-2 In this embodiment, a multifunctional road rescue paving device includes a road rescue vehicle carrier 1:

[0032] Two sets of road paving mechanisms 2 are installed on the road rescue vehicle carrier 1. The two sets of road paving mechanisms 2 are respectively arranged on one side of the road rescue vehicle carrier 1 and rotate on the road rescue vehicle carrier 1;

[0033] A second platform carrier 8 is detachably mounted on the road rescue vehicle carrier 1, and an arm adjustment mechanism 9 is mounted on the upper end surface of the second platform carrier 8;

[0034] A road surface environment detection mechanism 10 is mounted on the support arm adjustment mechanism 9 , and a road surface exploration camera body 11 is detachably mounted on the road surface environment detection mechanism 10 .

[0035] In this embodiment, the rescue paving device of the present application can be used as a "pioneer" to temporarily and quickly build roads after a natural disaster occurs, when the road is damaged and large vehicles and mechanical rescue equipment cannot reach the front line in the first time, thereby ensuring that important rescue materials and equipment arrive at the disaster relief site. The modular disassembly and assembly method of the pavement paving mechanism 2 and the pavement rescue vehicle carrier 1 of the present application can also realize the rapid, efficient and stable construction of rescue channels, and can also be automatically recycled after the first stage of the goal is completed, facilitating the subsequent rescue work. In terms of styling, while ensuring its functional reliability, the overall equipment has a certain flexibility, and the pavement paving mechanism 2 and the pavement environment detection mechanism 10 can be freely switched to achieve different emergency rescue tasks.

[0036] Furthermore, the road rescue vehicle carrier 1 of the present application can be equipped with four sets of road exploration camera bodies 11, so as to achieve good mobility and terrain adaptability. In actual use, the road rescue device of the present application can cope with various terrains such as mountains, wetlands and woodlands, and quickly reach the work site. In conjunction with the road environment detection mechanism 10 modularly assembled on the road rescue vehicle carrier 1, the road rescue paving device of the present application can also autonomously scan the terrain environment, so as to intelligently select a suitable route forward.

[0037] Furthermore, through the modularized road paving mechanism 2 and the second platform carrier 8 of the present application, the road paving mechanism 2 can quickly temporarily pave the damaged road, so that the search and rescue vehicles can pass quickly, and the road exploration camera body 11 set on the second platform carrier 8 can explore the road danger, and at the same time, the road exploration camera body 11 can provide accurate road information for the road rescue vehicle carrier 1, so as to determine the specific location and degree of road damage and whether there is a cavity underneath. Then the rescue personnel can drive the road rescue vehicle carrier 1 to move to the precise position based on this information, and then provide the paving of the fast road, which can avoid the waste of resources caused by blind construction in post-disaster road construction.

[0038] It should be noted that in order to enable the road rescue vehicle carrier 1 to better adapt to road surfaces of different terrains, in a preferred embodiment, two sets of mobile tracks 6 are installed on both sides of the road rescue vehicle carrier 1; the four sets of mobile tracks 6 are arranged in a triangular track structure, and a number of pin rings 7 are protruding on both sides of the road steel plate 3.

[0039] Furthermore, the road rescue vehicle carrier 1 is a large mobile vehicle carrier in the prior art. In a preferred embodiment, the road rescue vehicle carrier 1 is an unmanned vehicle carrier.

[0040] See also Figure 1-2 In order to quickly pave the rescue road surface for the rescue vehicles to pass through, the two groups of road paving mechanisms 2 in this embodiment both include a steel cable support arm 21 rotating on the road rescue vehicle carrier 1, and a pulley block 22 is installed on the top of the steel cable support arm 21. A plurality of road suspension steel cables 23 are connected to the pulley block 22, and a road steel plate 3 is suspended at the other ends of the plurality of road suspension steel cables 23.

[0041] In this embodiment, when the road rescue vehicle carrier 1 moves to the emergency road section, the user can lay the road steel plate 3 flat on the road rescue vehicle carrier 1 and control the rotation angle of the road paving mechanism 2 at the same time. After the inclination control of the road paving mechanism 2 is completed, the ends of several road suspension steel cables 23 are penetrated with several pin rings 7 on the road steel plate 3, so that the road paving mechanism 2 can quickly suspend the two sides of the road steel plate 3. At this time, the road paving mechanism 2 set can complete the paving of the road steel plate 3.

[0042] Furthermore, the rotation angles of the two sets of pavement paving mechanisms 2 are controlled by motors. In actual use, the motors for controlling the rotation angles of the pavement paving mechanisms 2 are installed inside the pavement rescue vehicle carrier 1. The rotation angles of the pavement paving mechanisms 2 are controlled by the motors, so that the pavement paving mechanisms 2 can suspend the pavement steel plates 3 at different heights.

[0043] It should be noted that in order to allow emergency rescue vehicles to quickly pass through the road steel plate 3, in a preferred embodiment, as shown in the embodiment Figure 1-2 As shown in the figure, an inclined ladder steel plate 4 is obliquely built at the rear end of the road rescue vehicle carrier 1; a secondary inclined plate 5 is welded at one end of the road steel plate 3, and the secondary inclined plate 5 and the road steel plate 3 are inclined.

[0044] In this embodiment, the inclined ladder steel plate 4 and the auxiliary inclined plate 5 are both inclined, so that the rescue vehicle can quickly move onto the road surface steel plate 3, so that the road surface steel plate 3 can be used as a temporary vehicle road to facilitate the rapid passage of the rescue vehicle.

[0045] See also Figure 3-6 In order to observe the environmental road surface in different terrain environments, so as to facilitate the safe passage of the road rescue vehicle carrier 1 of the present application, the road environment detection mechanism 10 in the present embodiment includes a positioning platform 101 arranged at the top of the second support arm 95, and two groups of linear guide rails 102 are vertically arranged on the side of the positioning platform 101, and two slider seats 103 are slidably arranged on the two groups of linear guide rails 102, and the sides of the four slider seats 103 are commonly connected to a platform plate 104; a base 108 is installed on the side of the platform plate 104, and the base 108 is U-shaped and has sliding blocks slidably arranged on both side ends. Rail 109, and clamping bars 110 are installed on the sides of the two slide rails 109; two light rods 111 are installed on the outer walls of the upper and lower sides of the base 108, and the second linear motor 112 is supported and installed by the light rods 111, and the ends of the two second linear motors 112 are arranged opposite to each other and are respectively connected to one of the slide rails 109; a side plate 105 is installed on the side of the positioning platform 101, and a first linear motor 106 is installed on the side plate 105; a connecting rod 107 is connected to the output end of the first linear motor 106, and the other end of the connecting rod 107 extends to be connected to the platform plate 104.

[0046] In this embodiment, when the user adjusts the road environment detection mechanism 10, the road exploration camera body 11 is first placed between the two clamping ends 110, and then the user connects the two second linear motors 112 to an external power supply, thereby driving the output ends of the two second linear motors 112 to move. At this time, the second linear motor 112 drives the slide rail 109, so that the slide rail 109 can drive the clamping bar 110 to move. When the two clamping bars 110 are in opposite motion, the clamping limit of the road exploration camera body 11 can be achieved through the set clamping bar 110.

[0047] Furthermore, when the road exploration camera body 11 is installed between the two clamping bars 110, the user can connect the first linear motor 106 to an external power supply. When the output end of the first linear motor 106 drives the platform plate 104 to move, the platform plate 104 cooperates with the connection between the linear guide rail 102 and the slider seat 103 to drive the base 108 and the road exploration camera body 11 to move vertically as a whole, thereby realizing the vertical height adjustment of the road exploration camera body 11.

[0048] Further preferably, in order to improve the road surface observation details of the road exploration camera body 11 and enable the road exploration camera body 11 to better adapt to different terrain environments and perform road surface observation, in a preferred embodiment, the present application also adds a set of arm adjustment mechanisms 9 on the second platform carrier 8, so that the road environment detection mechanism 10 is further compensated for its position through the arm adjustment mechanism 9; as shown in the embodiment Figure 3-4 As shown in the figure, the arm adjustment mechanism 9 includes a positioning seat 91 arranged on the upper end surface of the second platform carrier 8, the positioning seat 91 is U-shaped and welded to the second platform carrier 8, a first rotating motor 92 is assembled in the positioning seat 91, and a first arm 93 is sleeved on the outer side of the output end of the first rotating motor 92; a second rotating motor 94 is assembled on the other end of the first arm 93, and a second arm 95 is sleeved on the output end of the second rotating motor 94, and a connecting seat 96 is arranged at the end of the second arm 95, and the road environment detection mechanism 10 is vertically installed on the other end of the connecting seat 96.

[0049] In this embodiment, the user connects the first rotating motor 92 to a power source, and the first rotating motor 92 set at this time can drive the first arm 93 to rotate. At the same time, when the second rotating motor 94 is connected to a power source, the second rotating motor 94 set at this time can drive the second arm 95 to rotate an angle. During this period, through the bipolar adjustment of the first rotating motor 92 and the second rotating motor 94, the road environment detection mechanism 10 installed at the end of the second arm 95 can be freely adjusted at different angles.

[0050] The working principle of the above embodiment is:

[0051] In the first step, when the user uses the road rescue vehicle carrier 1 of the present application and performs paving operations on the rescue road surface, the road rescue vehicle carrier 1 is moved to the area environment to be rescued by controlling the movement of the road rescue vehicle carrier 1. In actual use, the road rescue vehicle carrier 1 is an existing mature vehicle carrier. When the road rescue vehicle carrier 1 moves to the rescue road section, the user can lay the road steel plate 3 flat on the road rescue vehicle carrier 1 and control the inclination angle of the road paving mechanism 2. When the inclination angle control of the road paving mechanism 2 is completed, the ends of several road suspension steel cables 23 are penetrated with several pin rings 7 on the road steel plate 3, so that the road paving mechanism 2 can quickly suspend the two sides of the road steel plate 3. At this time, the road paving mechanism 2 set can complete the paving of the road steel plate 3. Subsequently, the user tilts the inclined ladder steel plate 4 to build it on one side of the road rescue vehicle carrier 1, so as shown in the embodiment. Figure 2 As shown in the figure, a road built with steel plates is formed between the inclined ladder steel plate 4, the pavement steel plate 3 and the auxiliary inclined plate 5. In terms of application scenarios, the pavement steel plate 3 is suspended by the pavement paving mechanism 2, so that the pavement steel plate 3 can handle various disaster scenes, such as: landslides, slope collapse, landslides, boulder obstacles, bridge damage, temporary bridge erection, etc., so as to quickly pave a temporary rescue road for the rescue site.

[0052] In the second step, when the user does not need to use the pavement paving mechanism 2 and the pavement steel plate 3 for paving, the user can remove the pavement steel plate 3, and then install the second platform carrier 8 on the pavement rescue vehicle carrier 1 through bolts. When the second platform carrier 8 is installed, the arm adjustment mechanism 9 set on the second platform carrier 8 can provide different position adjustments for the pavement environment detection mechanism 10, and the pavement environment detection mechanism 10 can clamp and install the pavement exploration camera body 11. When the pavement exploration camera body 11 is installed on the pavement environment detection mechanism 10, the pavement exploration camera body 11 is installed. The surface exploration camera body 11 can be driven by the support arm adjustment mechanism 9 and the road environment detection mechanism 10, so as to perform free height adjustment and angle adjustment. Whether it is a high-altitude structure such as a beam, a platform or a low-lying area such as a collapsed ruin or a surface crack, it can achieve comprehensive coverage of search and rescue. At the same time, the road exploration camera body 11 of the present application can be adjusted to the optimal height to avoid obstacles or pass through narrow spaces to adapt to the complexity of the environment; for inclined, sunken or accumulated terrain, the road exploration camera body 11 with adjustable height can more efficiently observe difficult-to-detect road areas, thereby improving the versatility of road rescue.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
