DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0025] See also Figure 1-Figure 8The utility model provides a technical solution: a new type of widening bridge connection device, including two groups of assembling and fixing units 100, two groups of rotating parts 101 and disassembling components. When in use, screw holes are drilled on the assembling and fixing units 100, and mounting bolts are used to pass through the screw holes to connect and fix the new bridge or the old bridge together, so that the widening and fixing units 100 on both sides of the connection device are respectively fixed on the new bridge and the old bridge. The disassembling and assembling components include multiple groups of plate bodies 200, multiple groups of locking parts, multiple groups of fixing parts and limiting parts. The locking parts are located between the two ends of the rotating part 101 and the assembling and fixing units 100, and the fixing parts are located on the plate body 2 00 and the rotating member 101, the limiter is located on the plate body 200. When in use, there are 6 plates 200 in total, and the plates 200 are staggered. The locking member includes a screw 203 and an internal threaded tube 204. Both ends of the assembled fixing unit 100 are provided with a moving groove 202, and the end of the screw 203 is fixedly provided with a plug column 206. Both ends of the rotating member 101 are provided with a plug hole 208, and the end of the plug column 206 is inserted into the inside of the plug hole 208. The outside of both ends of the internal threaded tube 204 is fixedly provided with a retaining ring 205. The screw 203 is located inside the internal threaded tube 204. The corrugated tube 204 is located inside the movable groove 202. The fixing member includes a fixing plate 201. The fixing plate 201 is embedded and installed on the rotating member 101. Two sets of countersunk holes 207 are opened inside the fixing plate 201. The plate body 200 is respectively opened inside a groove 209 and two sets of screw holes 210. The end of the fixing plate 201 penetrates into the groove 209. The countersunk hole 207 is provided with a bolt. The working end of the bolt extends to the inside of the screw hole 210. The plate body 200 is located on the side of the rotating member 101. The plate body 200 is provided with a through hole 212. The plate body 200 is provided with a limiting column 211. When the new bridge and the old bridge sink and the plate body 100 starts to rotate and tilt, the limit column 211 will rotate in the through hole 212 in the plate body 200, and the end of the limit column 211 passes through the inside of the through hole 212. Through the designed disassembly and assembly components, when a part of the assembly fixing unit, the rotating part 101, etc. on the connecting device is deformed or damaged during use, it can be replaced separately, avoiding the traditional need to replace the connecting device as a whole, saving replacement costs, and allowing some intact parts on the connecting device to be used again, reducing waste rate and improving the use effect of the connecting device.

[0026] In this embodiment, preferably, both ends of the limit column 211 are externally sleeved with limit rings 300, and the limit rings 300 are provided with screws 301, and the working end of the screw 301 extends to the inside of the limit column 211. By combining the designed limit ring 300 and the screw 301, it is convenient to limit the limit column 211 inserted into the through hole 212 in the plate body 200 during use, and prevent the end of the limit column 211 from detaching from the through hole 212, which is convenient for use.

[0027] In this embodiment, preferably, the assembling and fixing unit 100 is a concave structure.

[0028] When the utility model is in use, after the wheels of the vehicle are on the connecting device, the connecting device supports the vehicle. When the new bridge or the old bridge sinks and misaligns, the assembling and fixing units 100 on the new bridge or the old bridge descend, driving one group of the assembling and fixing units 100 to descend. At this time, the descending rotating member 101 is affected and starts to tilt and rotate under the action of the plug column 206 and the plug hole 208, driving the plate body 200 to tilt and rotate. At this time, the limit column 211 will rotate in the through hole 212 in the plate body 200, and the interlaced plates 200 will be driven to expand and displace outward. At this time, the internal threaded tube 204 in the movable groove 202 slides to the left or right, so that the assembling and fixing units 100 on the new bridge and the old bridge can always be connected together, and the vehicle can pass through the connecting device normally.

[0029] When disassembling the deformed and damaged rotating part 101, the movable groove 202 is turned outward and unscrewed to drive the plug post 206 to rotate, and then the working end of the plug post 206 is disengaged from the inside of the socket 208 in the rotating part 101. At this time, the bolt on the fixing plate 201 is turned upward and loosened, and the working end of the bolt is disengaged from the inside of the screw hole 210. At this time, the rotating part 101 can be removed, and then the new rotating part 101 is taken out and installed back to the original position according to the above-mentioned reverse principle to replace the rotating part 101; when replacing and assembling the fixing unit 100, first follow the same principle as above to make the end of the plug post 206 disengage from the socket 208 inside the rotating part 101, and then Then remove the assembling and fixing unit 100 from the new bridge or the old bridge, take out the new assembling and fixing unit 100 and install it back to the original position according to the reverse principle mentioned above, and the assembling and fixing unit 100 can be replaced; when replacing the plate body 200, follow the same principle as above to make the working end of the bolt disengage from the inside of the screw mouth 210, and then unscrew the screw 301 in the limiting ring 300 on the limiting column 211, then the limiting ring 300 can be removed, and then the limiting column 211 is pulled out, and then the limiting column 211 is disengaged from the through hole 212 in the plate body 200, and then take out the new plate body 200 and follow the reverse principle mentioned above to replace the plate body 200.
