Description

Technical Field

[0001] This utility model relates to a connection device for a water transportation facility - a floating bridge or pontoon bridge, and more particularly to a positioning and docking device for a floating bridge or pontoon bridge module / unit during the erection of a floating bridge / pontoon bridge. Background Technology

[0002] Floating bridges / pontoon bridges have wide applications in both military and civilian fields. In military and disaster relief operations, it is often necessary to erect temporary floating bridges on water to facilitate the transportation of personnel and supplies. Currently, the docking of existing pontoon bridge and floating bridge modules requires manual dragging to align the two modules before inserting pins to connect them. Although some automatic locking technologies exist, the complex and varying water conditions make docking difficult and alignment challenging. The accuracy and speed of the alignment directly affect the efficiency of personnel and supply transportation. Therefore, the docking of existing pontoon bridge and floating bridge modules is time-consuming and labor-intensive, resulting in long erection times and low efficiency. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by proposing a rapid positioning and connection device for floating bridges and pontoon bridges. This device enables precise positioning and rapid connection of the connection structures of floating bridges and pontoon bridges, significantly reducing the docking time between the two modules and improving the connection efficiency of pontoon bridges and floating bridges.

[0004] Utility model technical solution:

[0005] This utility model addresses the shortcomings of existing technologies by breaking with convention and changing the approach. It proposes that the technical approach for connecting pontoon bridges and floating bridges should not be limited to improving the connection technology itself, but should focus on positioning the two pontoon bridge and floating bridge modules.

[0024] To make the technical concept and advantages of the invention clearer, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the following embodiments are only used to explain and illustrate preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Example

[0025] See Figure 1 , Figure 2 This utility model relates to a quick positioning and connection device for floating bridges and pontoon bridges, comprising a positioning mechanism and a connection mechanism. The positioning mechanism includes a positioning rod 108 fixedly connected to one of the two floating bridge or pontoon bridge units / modules to be connected, and a positioning mechanism fixedly connected to the other floating bridge or pontoon bridge unit / module and matching the positioning rod 108. The positioning mechanism consists of the positioning rod 108, a positioning baffle 103, a movable locking rod 106, a buffer spring 105, and a steel wire rope 10. 4. It consists of a winch 101; the positioning baffle 103 is fixedly connected to the floating bridge or pontoon bridge, the movable locking rod 106 is connected to the positioning baffle 103 through a buffer spring 105, the positioning baffle 103 and the winch 101 are fixedly connected to a floating bridge or pontoon bridge unit, and the positioning rod 108 is fixedly connected to another floating bridge or pontoon bridge unit; one end of the wire rope 104 is connected to the winch 101, and the other end passes through the strip ring 107 set at the front end of the movable locking rod 106 and is fixedly connected to the positioning baffle 103.

[0026] The movable lever 106 has a strip ring 107 at its front end, the position of which corresponds to the positioning rod 108. A winch 101 is fixed to a pontoon bridge or floating bridge, and the winch 101 is connected to a wire rope 104. The other end of the wire rope 104 passes through the strip ring 107 and is fixed to the positioning baffle 103. Figure 1 , Figure 2 As shown, the positioning rod 108 is fixed to the pontoon bridge 200, and the positioning baffle 103 and the hydraulic winch 101 are fixed to the pontoon bridge 100. One end of the wire rope 104 is fixed to the positioning baffle 103, and the other end passes through the strip ring 107 and is connected to the hydraulic winch 101.

[0027] This utility model comprises two sets of positioning and connecting mechanisms, installed in pairs at corresponding positions on the two floating bridge or pontoon bridge units / modules to be connected. The positioning rod 108 of the positioning mechanism and its matching positioning mechanism are also in two sets, respectively located at the corresponding ends of the connected floating bridge or pontoon bridge. The rapid connection process of the pontoon bridge is as follows: Figures 3-6As shown, when the two pontoon bridges reach the appropriate position, the steel wire ropes of the two pontoon bridges are hooked with iron hooks and pulled out and looped onto the corresponding positioning rods. Then, the two hydraulic winches are started to pull the two positioning rods into the horn-shaped openings formed by the two corresponding strip rings. When the two pontoon bridges are in a parallel position, the speed of the two hydraulic winches is controlled to make them move in parallel, compressing the springs and allowing the insertion connecting plate 118 of the connecting mechanism of the two pontoon bridges to smoothly enter the corresponding positioning groove 117.

[0028] like Figure 3 , Figure 4 As shown, the insertion connecting plate 118 is fixed to the pontoon bridge 200, and the positioning connecting plate 115 is fixed to the pontoon bridge 100. The front end of the positioning groove 117 of the positioning connecting plate 115 is trumpet-shaped, as shown... Figure 7 As shown. Example

[0029] The difference between the quick positioning and connection device for the floating bridge and pontoon bridge in this embodiment and that in embodiment 1 is that: further, the positioning baffle 103 is provided with a slide rail 102, the tail end of the movable locking rod 106 passes through the slide rail 102 provided on the positioning baffle 103, and the buffer spring 105 is provided between the positioning baffle 103 and the movable locking rod 106. Example

[0030] like Figure 1 , Figure 2 As shown, the quick positioning and connection device for the floating bridge / pontoon bridge in this embodiment differs from that in Embodiments 1 or 2 in that: The strip rings 107 are arranged in pairs, with the front portions of the two strip rings 107 facing outwards and forming a funnel shape corresponding to the positioning rod 108. The height of the extended portion of the positioning rod 108 matches the height of the strip rings 107, and a hook is provided at the top to facilitate the insertion of the wire rope 104 and prevent the wire rope from slipping. This allows the positioning rod 108 to be pulled into the funnel shape formed by the two strip rings 107 via the wire rope 104. Example

[0031] See Figure 4 , Figure 7The quick positioning and connection device for the floating bridge and pontoon bridge in this embodiment differs from the aforementioned embodiments in that: the connection mechanism of the floating bridge and pontoon bridge includes an insertion connecting plate 118 and a positioning connecting plate 115, a hydraulic cylinder 111, a transmission connecting plate 113, and a connecting pin 114. The piston rod 112 inside the hydraulic cylinder 111 is connected to the connecting pin 114 through the transmission connecting plate 113. The positioning connecting plate 115 and the hydraulic cylinder 111 are fixed on one floating bridge or pontoon bridge unit, and the insertion connecting plate 118 is fixed on another floating bridge or pontoon bridge unit. The positioning connecting plate 115 is provided with a pin hole 116 and a positioning groove 117, and the insertion connecting plate 118 is provided with a pin connection hole 119. The front end of the positioning groove 117 is a trumpet-shaped opening and corresponds to the insertion connecting plate 118.

[0032] The insertion connecting plate 118 and the positioning connecting plate 115 are respectively fixed to the corresponding ends of the two floating bridges or pontoon bridges to be connected. When the two winches 101 pull the floating bridges or pontoon bridges to the closing position, the insertion connecting plate 118 also enters the positioning groove 117. At this time, the connecting pin 114 is inserted into the pin connecting hole 119 and locked. See also Figure 5 , Figure 6 .

[0033] The power mechanism of the connecting pin 114 is a hydraulic cylinder 111. The other end of the connecting pin 114 is connected to the front end of the piston rod 112 of the hydraulic cylinder 111 via a transition connecting plate 113. One end of the transmission connecting plate 113 is connected to the piston rod 112, and the other end is connected to the connecting pin 114. The free end of the connecting pin 114 is inserted into the pin hole 116.

[0034] After confirming that the two pontoon bridges / floating bridges are joined, the hydraulic cylinders are activated to insert the pins into the pin connection holes, and the two pontoon bridges are connected. After use, the two pontoon bridges can be separated by operating in reverse order.

[0035] Compared with existing technologies, this utility model enables rapid and accurate positioning of pontoon bridge and floating bridge modules during the erection process, thereby achieving rapid erection of pontoon bridges and floating bridges and significantly improving the efficiency of military operations and disaster relief work.

Those skilled in the art, guided by existing technology, can make other modifications to the implementation of the present utility model without creative effort. Any modifications made within the spirit and principles of the present utility model, or any simple substitutions or equivalent replacements made using conventional technical means in the art, should be included within the protection scope of the present utility model.
