Description

Technical Field

[0001] This utility model relates to the field of rescue floating bridge technology, specifically a wire mesh rescue floating bridge. Background Technology

[0002] In disaster relief scenarios such as floods and earthquakes, pontoon bridges made of woven fabric are key equipment for ensuring the rapid transfer of personnel and supplies.

[0003] Based on the above, the following problems were found: Currently, most pontoon bridges for rescue are assembled by binding with straps. However, the environment at disaster relief sites is complex. Factors such as water flow and the passage of personnel and materials will exert continuous and enormous tension on the connection parts of the pontoon bridge. Ordinary straps are mostly made of nylon or polyester fiber. After long-term stress, immersion in moisture, or scratching by sharp objects, they are prone to loosening, wear, or even breakage, which seriously affects the smooth progress of rescue operations and endangers the lives of rescue personnel.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a woven fabric rescue pontoon bridge in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a woven fabric rescue pontoon bridge to solve the problem that most woven fabric rescue pontoon bridges mentioned in the background art are assembled by binding with straps. After long-term stress, immersion in moisture, or scratching by sharp objects, the straps are prone to loosening, wear, or even breakage.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A reusable pontoon bridge made of woven fabric includes a main body and a connecting mechanism. The main body includes a pontoon body with an inflation valve on one side of its upper end. The connecting mechanism includes two pairs of fixing frames, which are respectively embedded in one end and one side of the pontoon body. Sliding sleeves are inserted on both sides of each fixing frame, and fixing blocks are slidably inserted inside each sliding sleeve. Slots matching the fixing frames are opened on the other side and one end of the pontoon body, and fixing grooves that are adapted to the fixing blocks are opened inside each slot. A pair of retainers are installed at the bottom of each fixing frame, and screws are rotatably connected to the opposite ends of each pair of retainers. Threaded grooves are opened on the facing surfaces of each fixing block, and the threaded grooves are threadedly connected to the screws.

[0008] Furthermore, each of the retainers is rotatably connected to a connecting shaft, and the two ends of the connecting shaft are respectively connected to the opposing ends of a pair of screws, the threads of the pair of screws being arranged in opposite directions.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the connecting shaft connects a pair of screws with opposite threads. When the connecting shaft is rotated, a pair of fixing blocks can move synchronously in opposite directions, ensuring that the fixing blocks are inserted into or pulled out of the fixing slots at the same time, thereby improving the efficiency and convenience of pontoon bridge splicing and disassembly.

[0010] Furthermore, the inner side of each fixing frame is rotatably connected to a rotating shaft, and one end of the rotating shaft is fitted with a first bevel gear.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the rotating shaft and the first bevel gear provide a connecting component for power transmission. Through the first bevel gear, power can be transmitted from the rotating shaft to the screw to drive the fixed block, which facilitates operation.

[0012] Furthermore, a second bevel gear is fitted onto one end of the connecting shaft, and the second bevel gear meshes with the first bevel gear.

[0013] The beneficial effect of adopting the above-mentioned further scheme is that the second bevel gear meshes with the first bevel gear, transmitting the rotation of the rotating shaft to the connecting shaft, thereby driving the screw to rotate, realizing the effective transmission and conversion of power, and ensuring the synchronous movement of the fixed block.

[0014] Furthermore, a worm gear is fitted at one end of the rotating shaft, and a worm is rotatably connected inside the fixed frame on one side of the worm gear, with the worm and the worm gear meshing with each other.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the worm and the worm wheel mesh with each other, and by utilizing the self-locking characteristic of the worm wheel and worm gear transmission, the worm wheel can be prevented from rotating on its own after the fixed block is inserted into the fixed groove, thus ensuring the stability of the floating bridge after splicing.

[0016] Furthermore, the top of the worm gear extends through the floating bridge body to the outside and is fitted with a rotating wheel. The upper end of the floating bridge body, located above the rotating wheel, is equipped with a stop block.

[0017] The advantages of adopting the above-mentioned further solution are that the rotating wheel is installed at the top of the worm gear, which makes it easy for the operator to manually rotate the worm gear and control the movement of the fixed block. The operation is simple and convenient, and the floating bridge can be quickly assembled and disassembled in emergency rescue situations. In addition, by installing the stop block, it can prevent people from accidentally kicking the rotating wheel while walking.

[0018] Furthermore, fluorescent strips are fixedly installed on both sides of the upper end face of the floating bridge body, and several anti-slip strips are fixedly installed on the upper end face of the floating bridge body between a pair of fluorescent strips.

[0019] The beneficial effects of adopting the above-mentioned further solutions are that the fluorescent strips can emit light at night or in dim light conditions, making it easier for rescuers to identify the location of the pontoon bridge and improving rescue safety; the anti-slip strips increase the friction of the pontoon bridge surface, preventing rescuers from slipping when walking on the pontoon bridge and ensuring personnel safety.

[0020] Furthermore, pull rings are fixedly installed at the four corners of the upper end face of the floating bridge body, and the pull rings are made of nylon.

[0021] The beneficial effect of adopting the above-mentioned further solution is that the nylon pull ring has the characteristics of high strength and wear resistance, making it easy for rescuers to pull and move the pontoon bridge.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: The main body of the pontoon bridge provides a floating foundation, and the inflation valve facilitates the inflation and deflation of the pontoon bridge body; the connecting mechanism's fixing frame, sliding sleeve, and fixing block cooperate, and through the threaded connection of the screw and the threaded groove, the fixing block can be inserted into the fixing groove of the slot, realizing the splicing of multiple pontoon bridge bodies, meeting the needs of different rescue scenarios for the length and area of ​​the pontoon bridge; the worm gear meshes with the worm wheel, and by utilizing the self-locking characteristic of the worm gear transmission, after the fixing block is inserted into the fixing groove, it can prevent the worm wheel from rotating on its own, ensuring the stability of the pontoon bridge after splicing; the rotating wheel is installed at the top of the worm gear, which is convenient for the operator to manually rotate the worm gear to control the movement of the fixing block. The operation is simple and convenient, and the pontoon bridge can be quickly spliced ​​and disassembled in emergency rescue situations. Furthermore, by installing a stop block, it can prevent personnel from accidentally kicking the rotating wheel during walking. Attached Figure Description

[0029] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0030] Example 1

[0031] Please see Figures 1-5 This utility model provides a technical solution: a pontoon bridge for rescue using woven fabric, comprising a main body 1 and a connecting mechanism 2. The main body 1 includes a pontoon body 101, with an inflation valve 103 on one side of the upper end of the pontoon body 101. The connecting mechanism 2 includes two pairs of fixing brackets 201, which are respectively embedded in one end and one side of the pontoon body 101. Sliding sleeves 205 are inserted on both sides of the fixing brackets 201, and fixing blocks 202 are slidably inserted inside the sliding sleeves 205. Slots 106 matching the fixing brackets 201 are opened on the other side and one end of the pontoon body 101, and fixing grooves 107 adapted to the fixing blocks 202 are opened inside the slots 106. Each bottom end is equipped with a pair of retainers 206, and the opposite ends of each pair of retainers 206 are rotatably connected to screws 207. The opposing surfaces of the fixing blocks 202 are provided with threaded grooves 211, which are threadedly connected to the screws 207. The floating bridge body 101 of the main body 1 provides a floating foundation, and the inflation valve 103 facilitates the inflation and deflation of the floating bridge body 101. The fixing bracket 201, sliding sleeve 205, and fixing block 202 of the connecting mechanism 2 cooperate and are threadedly connected to the screws 207 and the threaded grooves 211. The fixing block 202 can be inserted into the fixing groove 107 of the slot 106 to realize the splicing of multiple floating bridge bodies 101, which meets the requirements of different rescue scenarios for the length and area of ​​the floating bridge.

[0032] Please see Figures 1-5A connecting shaft 208 is rotatably connected between each pair of retainers 206. The two ends of the connecting shaft 208 are respectively connected to the opposite ends of a pair of screws 207. The threads of the pair of screws 207 are opposite. A rotating shaft 204 is rotatably connected to the inner side of each fixing bracket 201. A first bevel gear 210 is fitted onto one end of the rotating shaft 204, and a second bevel gear 209 is fitted onto one end of the connecting shaft 208. The second bevel gear 209 meshes with the first bevel gear 210. A worm gear 212 is fitted onto one end of the rotating shaft 204. The fixing bracket 201... Inside the pontoon body 101, a worm 203 is rotatably connected to one side of the worm gear 212. The worm 203 meshes with the worm gear 212. The top of the worm 203 extends through the pontoon body 101 to the outside and is fitted with a rotating wheel 213. A stop block 214 is installed on the upper end of the pontoon body 101 above the rotating wheel 213. A connecting shaft 208 connects to a pair of screws 207 with opposite threads. When the connecting shaft 208 is rotated, a pair of fixed blocks 202 can move synchronously in opposite directions, ensuring that the fixed blocks 202 are inserted or pulled out simultaneously. The fixed slot 107 improves the efficiency and convenience of pontoon bridge assembly and disassembly. The rotating shaft 204 and the first bevel gear 210 provide a connecting component for power transmission. Through the first bevel gear 210, power can be transmitted from the rotating shaft 204 to the screw 207, thereby driving the fixed block 202 and facilitating operation. The second bevel gear 209 meshes with the first bevel gear 210, transmitting the rotation of the rotating shaft 204 to the connecting shaft 208, which in turn drives the screw 207 to rotate, achieving effective power transmission and conversion and ensuring the synchronization of the fixed block 202. The worm gear 203 engages with the worm wheel 212. Utilizing the self-locking characteristic of the worm gear transmission, after the fixed block 202 is inserted into the fixed groove 107, the worm wheel 212 is prevented from rotating on its own, ensuring the stability of the pontoon bridge after assembly. The rotating wheel 213 is installed at the top of the worm gear 203, making it easy for operators to manually rotate the worm gear 203 to control the movement of the fixed block 202. The operation is simple and convenient, and the pontoon bridge can be quickly assembled and disassembled in emergency rescue situations. Furthermore, by installing the stop block 214, the rotating wheel 213 can be prevented from being accidentally kicked by personnel during walking.

[0033] Please see Figures 1-5 Fluorescent strips 104 are fixedly installed on both sides of the upper end face of the pontoon bridge body 101. Several anti-slip strips 105 are fixedly installed between a pair of fluorescent strips 104 on the upper end face of the pontoon bridge body 101. Pull rings 102 are fixedly installed at the four corners of the upper end face of the pontoon bridge body 101. The pull rings 102 are made of nylon. The fluorescent strips 104 can glow at night or in dim light, making it easier for rescuers to identify the location of the pontoon bridge and improving rescue safety. The anti-slip strips 105 increase the friction of the surface of the pontoon bridge body 101 to prevent rescuers from slipping when walking on the pontoon bridge and ensure personnel safety. The nylon pull rings 102 have the characteristics of high strength and wear resistance, making it easy for rescuers to pull and move the pontoon bridge.

[0034] Working principle

[0035] In use, the floating bridge body 101 is first inflated through the inflation valve 103 to make it float on the water surface. When it is necessary to assemble the floating bridge, the fixing brackets 201 of the adjacent floating bridge bodies 101 are aligned with the slots 106 and inserted. Rotating the rotating wheel 213 drives the worm gear 203 to rotate. The worm gear 203 meshes with the worm wheel 212, driving the rotating shaft 204 and the first bevel gear 210 to rotate. The first bevel gear 210 drives the connecting shaft 208 to rotate through the meshing second bevel gear 209. Because the threads of the screws 207 at both ends of the connecting shaft 208 are opposite, the pair of fixing blocks 202 are aligned. The steps are reversed, and the sliding sleeve 205 is inserted into the fixing groove 107. The self-locking characteristic of the worm gear is used to lock the position and complete the splicing. When disassembling, the rotating wheel 213 is rotated in the reverse direction, and the fixing block 202 is simultaneously removed from the fixing groove 107, so that the floating bridge body 101 can be separated. During the rescue, the fluorescent strip 104 provides position marking in low light environment, the anti-slip strip 105 prevents people from slipping, the nylon pull ring 102 facilitates the towing and transportation of the floating bridge, and the stop block 214 prevents accidental contact with the rotating wheel 213. All components work together to achieve rapid splicing, stable floating and safe rescue of the floating bridge.
