Description

Technical Field

[0001] This invention relates to the field of emergency rescue technology, and more specifically, to a mobile emergency rescue conveyor. Background Technology

[0002] Mobile emergency rescue conveyors are a type of continuous belt conveyor system with autonomous mobility and rapid deployment. They typically consist of a power system, conveyor belt, frame, chassis, and control system. They are mechanized transportation equipment used to quickly establish a temporary and controllable "lifeline" in complex, harsh, or inaccessible disaster sites.

[0003] According to patent document CN106364856A, a mobile long-distance material throwing system is disclosed. Its technical solution includes: a tracked chassis, hydraulic outriggers, a storage hopper, a corrugated sidewall conveyor, a telescopic boom system, a vertical luffing cylinder, a slewing device, a rotating mechanism, a high-speed conveyor, an acceleration device, a hydraulic and electrical control system, and a driver's cab. This invention has strong adaptability to work sites, solving the problem of bulk materials being difficult to reach the work area due to obstacles or road restrictions at the construction site, reducing labor input, shortening the construction period, and improving construction quality. During fire emergency rescue operations, while maintaining a sufficient safe distance from danger, it can throw fire extinguishing materials over long distances to the danger zone, meeting the requirements of safe, reliable, mobile, rapid, and comprehensive emergency rescue operations.

[0004] In the event of a natural disaster, traditional rescue transportation methods may be difficult to deploy quickly due to the complex environment at the disaster site and the severe damage to transportation infrastructure such as roads and bridges. Faced with harsh terrain conditions, damaged transportation routes, and the threat of potential secondary disasters, conventional vehicles and large equipment often cannot pass smoothly. This makes it difficult for relief supplies, medical equipment, and professional rescue personnel to reach the core disaster area in a timely manner, which seriously affects the response speed and efficiency of rescue operations. Such delays may not only lead to more casualties but also exacerbate property and social losses, thereby expanding the overall impact of the disaster. Summary of the Invention

The inner wall of the front side of the concave connecting plate 4112 is fixedly connected to the conveyor body 4114.

Third conveyor push blocks 425 are fixedly connected to the left and right sides of the third conveyor 424. The outer sides of the two third conveyor push blocks 425 extend to the outer sides of the two L-shaped vertical guide side plates 422. The bottom outer sides of the two third conveyor push blocks 425 are fixedly connected to the top of the two third electric push rods 4113. When a natural disaster occurs and rescue operations are needed, rescue personnel first drive the transport truck 1 to a suitable location at the disaster site to begin rescue operations. Then, they activate the electric push rod 317, which pushes the horizontal L-shaped push-pull block 318 to move rearward. This movement causes the columnar horizontal rotating rod 3110 to slide obliquely downward along the inner wall of the inclined guide groove 314 on the side plate 313. Simultaneously, the gear 3111 at the right end of the columnar horizontal rotating rod 3110 meshes with the helical rack rod 315, causing the tilting plate 319 to rotate the L-shaped rotating plate 3113 at its top to the rearward. This rotates the entire rescue transport machine 4 to an angle tilted towards the rear top, while simultaneously causing the support frame 32 to face... At the bottom, the second electric push rod 412 can be activated to pull the push-pull plate 414, which will drive the two push-pull blocks 415 to move forward. The two push-pull blocks 415 moving forward will drive the push-pull block guide rod 417 connected to them to move forward as well, thereby causing the retraction connecting rod 418 and the retraction outer connecting rod 419 to rotate. This rotation process will cause the two sets of convex push-pull blocks 4110 on the left and right to move upward. As the convex push-pull blocks 4110 rise, the lifting plate 4111 will also rise, thereby lifting the concave connecting plate 4112 and the conveyor body 4114 fixed on it together. During the process of the conveyor body 4114 rising, the bottom of its outer wall will slide inside the concave guide plate 413 to ensure the stability of the rise. Once the main body of the conveyor 4114 has risen to a suitable height, rescuers can activate the two third electric push rods 4113 as needed. The activation of the third electric push rods 4113 will push the third conveyor push block 425 upward, thereby causing the third conveyor 424 to slide upward on the inner side of the two L-shaped vertical guide side plates 422. In this way, the third conveyor 424 can adjust the height difference between itself and the second conveyor 423 according to the specific situation at the rescue site, so as to better transport materials. Throughout the rescue process, rescuers can precisely control the angle and height of the rescue conveyor 4 and the extent of deployment of the conveyor component 42 by controlling the start, stop and extension of the electric push rod 317, the second electric push rod 412 and the third electric push rod 4113, thereby meeting the needs of different rescue scenarios. This mobile emergency rescue conveyor has the advantages of flexible operation, convenient adjustment and wide applicability, and can provide strong support for natural disaster relief operations. At the same time, as the two lifting plates 4111 move to the top, the two rotating side plates 324 will move upward synchronously with the lifting plates 4111. This will cause the columnar horizontal push rod 323 to move in the support frame 32. The movement of the columnar horizontal push rod 323 will cause the two second rotating inclined rods 326 to rotate around the axis rod 327. At the same time, through the linkage between the rotating inclined rod 325 and the columnar horizontal rod 328, the two bottom rotating side rods 3210 will drive the L-shaped support plate 3211 to unfold outward. During the sliding process of the L-shaped support plate slider 3212 on the inner wall of the L-shaped guide side plate 322, a stable triangular support structure will be formed to ensure the structural strength of the rescue conveyor 4 in the unfolded state. When the conveying component 42 is fully unfolded, the rescuers can monitor the load data of each electric push rod in real time through the cab control system of the conveyor truck 1, and feed back the equipment status to the rear command center through the wireless transmission module, providing data support for the accurate delivery of subsequent rescue materials. In addition, the hoist 2 plays an important role in rescue operations. When large materials or equipment need to be hoisted to a high place or a specific location at the rescue site, rescuers can operate the hoist 2 and use its powerful lifting capacity to lift the materials smoothly and safely and transport them to the target location. The design of the hoist 2 fully considers the special needs of emergency rescue and has the characteristics of easy operation, strong lifting capacity and good stability.

[0022] Working principle of the invention: When a natural disaster occurs and rescue is needed, rescuers first drive the transport truck 1 to a suitable location at the disaster site to carry out rescue operations. Then, the electric push rod 317 is activated, which pushes the horizontal L-shaped push-pull block 318 to move backward. The horizontal L-shaped push-pull block 318 moves backward, thereby causing the columnar horizontal rotating rod 3110 to slide obliquely downward on the inner wall of the inclined guide groove 314 opened in the side plate 313. At the same time, the gear 3111 at the right end of the columnar horizontal rotating rod 3110 meshes with the helical rack rod 315, causing the tilting plate 319 to drive the L-shaped rotating plate 3113 at its top to rotate backward, thereby rotating the entire rescue transport machine 4 to an angle tilted towards the rear top, while simultaneously causing the support frame to... 32. With the bottom facing down, the second electric push rod 412 can then be activated to pull the push-pull plate 414, causing the two push-pull blocks 415 to move forward. The forward movement of the two push-pull blocks 415 will also cause the connected push-pull block guide rod 417 to move forward, thereby causing the retraction connecting rod 418 and the retraction outer connecting rod 419 to rotate. This rotation will cause the left and right sets of convex push-pull blocks 4110 to move upward. As the convex push-pull blocks 4110 rise, the lifting plate 4111 will also rise, thus lifting the concave connecting plate 4112 and the conveyor body 4114 fixed thereon together. During the ascent of the conveyor body 4114, the bottom of its outer wall will slide inside the concave guide plate 413 to ensure smooth ascent. Once the conveyor body 4114 rises to a suitable height, rescue personnel can activate the two third electric push rods 4113 as needed. Activation of the third electric push rods 4113 will push the third conveyor push block 425 upwards, thereby causing the third conveyor 424 to slide upwards along the inner sides of the two L-shaped vertical guide plates 422. In this way, the third conveyor 424 can adjust its height difference with the second conveyor 423 according to the specific conditions of the rescue site, facilitating better material transport. Simultaneously, as the two lifting plates 4111 move upwards, the two... The rotating side plate 324 moves upward synchronously with the lifting plate 4111, which in turn drives the columnar horizontal push rod 323. The movement of the columnar horizontal push rod 323 in the support frame 32 causes the two second rotating inclined rods 326 to rotate around the axis rod 327. At the same time, through the linkage between the rotating inclined rod 325 and the columnar horizontal rod 328, the two bottom rotating side rods 3210 drive the L-shaped support plate 3211 to unfold outward. During the process of the L-shaped support plate slider 3212 sliding on the inner wall of the L-shaped guide side plate 322, a stable triangular support structure is formed to ensure the structural strength of the rescue conveyor 4 in the unfolded state.
