Description

Technical Field

[0001] This invention relates to the field of lightweight gantry crane technology, and more particularly to a mobile mechanized vehicle-mounted gantry crane. Background Technology

[0002] Lightweight pontoon bridges have three main uses: assembled pontoon bridges, pontoon bridges, and pontoon hull boats used as inflatable boats. Assembled pontoon bridges are the primary function, ensuring that light wheeled equipment and personnel can overcome obstacles in small rivers. They can also be used as pontoon bridges or structural water operation platforms. The pontoon hull boats can be used independently as inflatable boats. Lightweight pontoon bridges are particularly important in emergency rescue operations during floods.

[0003] For example, in the prior art, Chinese invention patent application document with publication number CN107503280 A discloses a lightweight, air-droppable ferry pontoon bridge, which is mainly composed of bridge piers, bridge decks, crossbeams between pontoons, gangplanks, airbags, and net bags. This ferry pontoon bridge is lightweight, air-droppable, has a large load capacity, high speed when fully loaded, and the bow and stern pontoons can be launched on their own. It also overcomes the defects of existing pontoon bridges, such as low load-bearing capacity, low adaptability to flow velocity, manual erection, and complexity.

[0004] However, the above-mentioned ferry bridge has the following technical problems in its use:

[0005] 1. The bridge piers, bridge decks, gangplanks, and crossbeams between the piers are spliced ​​together by various joints. Due to the large number of joints, the assembly and disassembly process of the gantry bridge is complicated, which prolongs the assembly / disassembly operation time and is not conducive to quickly overcoming river obstacles.

[0006] 2. The fixed and unchanging structure of the pontoon boats limits their load capacity. Although the airbags increase the overall load capacity of the pontoon bridge, the load capacity of each individual pontoon boat remains unchanged. This limits the amount of supplies and personnel that can be transported when the pontoon boats are used as assault boats. Moreover, the airbags are located on the outside of the pontoon boats, making them susceptible to external damage, such as contact with river rocks, tree branches, or other sharp objects encountered during transport, which reduces the pontoon bridge's load capacity.

[0007] Therefore, it is necessary to improve the gantry bridge in the existing technology. Summary of the Invention

[0008] This invention provides a mobile mechanized vehicle-mounted gantry, which offers the advantages of convenient and rapid assembly and disassembly, increased load capacity, and guaranteed safety. The specific technical solution is as follows:

[0009] A mobile mechanized vehicle-mounted gantry crane, comprising:

[0010] A transport vehicle, the transport vehicle including a transport platform, the transport platform extending along a first direction and having a driver's cab connected to one end thereto;

[0011] A panel assembly is detachably connected to the end of the transport plate away from the cab. The panel assembly includes a plurality of bridge panels that are rotatably connected in sequence. Each bridge panel is elongated and its rotation axis is parallel to its width direction. A locking component is provided between two adjacent bridge panels to lock them in a folded position and an unfolded position so that the panel assembly can be adjusted to a folded state and an unfolded state, respectively. In the folded state, any two adjacent bridge panels in the panel assembly are facing each other and close together. In the unfolded state, all bridge panels in the panel assembly are located on the same plane.

[0012] The end plate assembly includes two ramps with a storage station and a bridging station. Under the storage station, the two ramps are detachably connected to the upper sides of the transport plate and, together with the folded panel assembly, the transport plate, and the cab, form a transport compartment with an open top. Under the bridging station, the two ramps are detachably connected to both ends of the panel assembly to form a bridging structure for the transport vehicle to pass through.

[0013] The bridge pier boat is movable on the transport platform and outside the transport vehicle via a panel assembly connected to the transport platform in its unfolded state. The bridge panel is detachably laid on top of the bridge pier boat to allow the transport vehicle to overcome river obstacles by crossing the bridge.

[0014] Furthermore, in order to facilitate locking the rotation angle of the two bridge panels to adjust the state of the panel assembly, the side of the bridge panel is provided with a first threaded sleeve. The rotation axis of the first threaded sleeve is parallel to the width direction of the bridge panel, and the axis of the first threaded sleeve is perpendicular to the rotation axis of the first threaded sleeve. The locking assembly includes a first screw that is threadedly connected to two adjacent first threaded sleeves.

[0015] Furthermore, to facilitate the connection between the scaffolding and the bridge deck and transport plate, a second threaded sleeve is rotatably provided on the side of the scaffolding. The rotation axis of the second threaded sleeve is parallel to the width direction of the scaffolding, and the axis of rotation of the second threaded sleeve is perpendicular to the rotation axis of the second threaded sleeve. The second threaded sleeve is threadedly connected to a second screw, and the second threaded sleeve is connected to the first threaded sleeve or the transport plate through the second screw.

[0016] Furthermore, to facilitate the transportation of the bridge pier boat via the unfolded panel assembly, a connector is provided at the end of the transport plate away from the cab. The connector is provided with a first socket and a second socket distributed along a first direction and extending in a vertical direction. The first socket is located between the second socket and the transport plate. The first socket is engaged with a first threaded sleeve located at one end of the panel assembly via a fixed plug rod. The second socket is engaged with one of the first threaded sleeves via a movable plug rod.

[0017] Furthermore, to facilitate the fixed storage of the panel assembly, the fixed insert rod and the movable insert rod are threaded together by a third screw, and a positioning frame is provided on the transport plate, with the rod portion of the third screw passing through the positioning frame.

[0018] Furthermore, to facilitate the storage of the pontoon boats in the storage compartment, the pontoon boats include a bow boat and a stern boat, which are rotatably connected. A locking component is provided between the bow boat and the stern boat to lock them in the unfolding position and the folding position. In the folding position, the bow boat and the stern boat are adjacent to each other and their openings face each other. In the unfolding position, the bow boat and the stern boat are combined to form an assault boat.

[0019] Furthermore, to facilitate locking the relative positions of the bow and stern, the locking assembly includes a locking bar, a locking sleeve, and a locking screw. The locking bar has a locking opening extending along its length. Of the bow and stern, one is fixedly connected to the locking screw, and the other is rotatably connected to the locking bar with its rotation axis perpendicular to the length direction of the locking bar. The locking screw passes through the locking opening and is threadedly connected to the locking sleeve.

[0020] Furthermore, in order to facilitate the secure installation of the bridge panel in the unfolded state panel assembly onto the bridge foot boat, one side of the bridge panel is provided with two positioning slots that extend along its width and are arranged side by side. The bridge foot boat is fixed with positioning protrusions that are arranged along its length. When the bridge panel is installed on the bridge foot boat, the bridge foot boat and the bridge panel are engaged through the two positioning slots and the positioning protrusions.

[0021] Furthermore, in order to increase the load capacity of the bridge pier boat, both the bow boat and the stern boat include an upper hull and a lower hull. The upper hull has a downward-facing, closed-loop positioning sleeve. The upper hull is sealed and fitted onto the upper part of the lower hull through the positioning sleeve. An elastic sealing sleeve is provided between the inner wall of the positioning sleeve and the top of the lower hull. A telescopic unit is provided between the upper hull and the lower hull to drive them to slide relative to each other along the height direction of the bridge pier boat.

[0022] Furthermore, to facilitate the use of the pontoon boat as an assault boat and to facilitate the maintenance of the watercraft, the pontoon boat is threadedly connected to the watercraft via a fourth screw. The watercraft has a storage position and a navigation position. In the storage position, the watercraft is fixed between the bow and stern of the folding position. In the navigation position, the watercraft is fixed to the end of the bow away from the stern.

[0023] This invention features an ingenious structural design, is easy to use, and can be quickly assembled and adjusted. The ramp in the unfolded panel assembly not only facilitates the loading and unloading of the bridge pier boats but can also be connected with the ramp to form a bridge for transport vehicles to cross rivers. When the panel assembly is adjusted to a folded state, it works with the ramp to surround the bridge pier boats on the transport platform, facilitating vehicle transport and reducing transportation costs compared to air transport.

[0058] To better understand the purpose, function, and specific design of this invention, the mobile mechanized vehicle-mounted gantry bridge of this invention will be described in further detail below with reference to the accompanying drawings.

[0059] like Figures 1-10 As shown, the mobile mechanized vehicle-mounted gantry of the present invention includes:

[0060] The transport vehicle 100 includes a transport platform 101, which extends along a first direction and has a driver's cab 102 connected to one end.

[0061] A panel assembly is detachably connected to the end of the transport plate 101 away from the cab 102. The panel assembly includes a plurality of bridge panels 200 that are rotatably connected in sequence. Each bridge panel 200 is long and its rotation axis is parallel to its width direction. A locking component is provided between two adjacent bridge panels 200 to lock them in a folded position and an unfolded position so that the panel assembly can be adjusted to a folded state and an unfolded state respectively. In the folded state, any two adjacent bridge panels 200 in the panel assembly are facing each other and close together. In the unfolded state, each bridge panel 200 in the panel assembly is located on the same plane.

[0062] The end plate assembly includes two ramps 300 with a storage station and a bridging station. Under the storage station, the two ramps 300 are detachably connected to the upper sides of the transport plate 101 and together with the folded panel assembly, the transport plate 101 and the cab 102 to form a transport compartment with an open top. Under the bridging station, the two ramps 300 are detachably connected to both ends of the panel assembly to form a bridging for the transport vehicle 100 to pass through.

[0063] The bridge pier boat 400 moves on the transport plate 101 and outside the transport vehicle 100 via a panel assembly connected to the transport plate 101 in the unfolded state. The bridge panel 200 is detachably laid on top of the bridge pier boat 400 so that the transport vehicle 100 can overcome river obstacles by bridging the bridge.

[0064] Specifically, in this invention, the transport vehicle 100 is preferably a medium- or heavy-duty truck, mainly serving as a transport carrier for the panel assembly, end face assembly, and bridge pier 400, used to transport the panel assembly, end face assembly, and bridge pier 400 to the location where they need to cross river obstacles. The transport vehicle 100 includes a chassis 104, with a rectangular plate-like transport plate 101 fixed on top of the chassis 104, the length direction of the transport plate 101 being the first direction; two panel assemblies are provided. During the operation of the transport vehicle 100, such as... Figure 1 As shown, both panel assemblies are in a folded state and are distributed along the width direction of the transport plate 101 on both sides above the end of the transport plate 101 away from the cab 102; there are two end plate assemblies. During the operation of the transport vehicle 100, as... Figure 1 As shown, two end plate assemblies are distributed along the length of the transport plate 101. Each end plate assembly corresponds to one of the two panel assemblies and together with the transport plate 101 and the cab 102, they form a storage compartment with an open top, which is used to store four bridge pier boats 400 that are distributed adjacent to each other along the length of the transport plate 101. Compared with airdropping by helicopters or other flying devices, this invention uses the transport vehicle 100 as a carrier for transportation, which can effectively reduce transportation costs.

[0065] After the transport vehicle 100 arrives at the riverbank, it adjusts the panel assembly to its unfolded state, so that each bridge panel 200 in the panel assembly is on the same plane, forming a long strip-shaped plate structure, such as... Figure 2 As shown, one end of the plate-like structure is then connected to the transport plate 101, and the other end is placed on the ground to form a ramp. This facilitates the sliding of the bridge foot boat 400 on the transport plate 101 down the ramp. The ramp allows the bridge foot boat 400 to detach from the transport vehicle 100 and the bridge deck 200.

[0066] After transporting the four pier boats 400 to the ground using the method described above, they are pushed into the water and arranged sequentially along their width. Then, the unfolded panel assembly is removed. The panel assembly contains four bridge panels 200, each corresponding to one of the four pier boats 400. Each bridge panel 200 is laid on top of the pier boat 400. The ramps 300 in the end panel assembly are then removed, and two ramps 300 are connected to the bridge panels 200 at the end of the unfolded panel assembly. This allows the two ramps 300 and the four bridge panels 200 to combine and form a bridge. The two ends of the bridge connect to the banks of the river. Figure 3 As shown, this facilitates the transport vehicle 100 to travel on the bridge and pass through obstacles such as rivers.

[0067] After the transport vehicle 100 passes the obstacle, the ramp 300 is installed on the transport plate 101. The unfolded panel assembly is then removed from the four gantry boats 400. One of the gantry boat panels 200 is connected to the rear end of the transport plate 101, that is, the end away from the cab 102, to form an upward ramp. This allows the four gantry boats 400 to slide up the ramp onto the transport plate 101 in sequence. Once the four gantry boats 400 have returned to the transport plate 101, the panel assembly is adjusted to the storage position and fixed to the transport plate 101, thus completing the entire installation of the panel assembly. At this point, the transport vehicle 100 can continue to travel after passing the river obstacle.

[0068] In use, the bridge panels 200 in the panel assembly are rotatably connected without the need for joints. When used as an assembly of aqueduct gate boats, the panel assembly only needs to be adjusted to the unfolded state, so that the pier boat 400 can slide down through the inclined bridge panels 200 and enter the water. The bridge panels 200 are then laid on the pier boat 400, and the bridge panels 200 at the end plate are connected to the gangplank 300. The entire assembly and disassembly operation can be completed quickly and conveniently.

[0069] A further improvement is that the side of the bridge deck 200 has a first threaded sleeve 501 that rotates, the rotation axis of the first threaded sleeve 501 is parallel to the width direction of the bridge deck 200, the axis of the first threaded sleeve 501 is perpendicular to the rotation axis of the first threaded sleeve 501, and the locking assembly includes a first screw 502 that is threadedly connected to two adjacent first threaded sleeves 501.

[0070] Specifically, such as Figure 5 and Figure 3 As shown, in the panel assembly, the four bridge panels 200 have the same structure. The surface of the bridge panel 200 is rectangular. Both ends of the bridge panel 200 are provided with several sockets arranged side by side along its own width direction. The two ends are integrally formed with through sockets and first sleeves 202 extending along the width direction of the bridge panel 200. A connecting block 220 is provided between two bridge panels 200. Connecting sleeves 221 are integrally formed on both sides of the connecting block 220. The circumferential inner wall of the connecting sleeve 221 is sealed to the circumferential outer edge of the first sleeve 202. In this way, the relative rotational connection of the two bridge panels 200 is realized. The inner side of the first sleeve 202 is sealed by a first rotating rod 500, which can rotate around its own axis inside the first sleeve 202. Both ends of the first rotating rod 500 are integrally connected to first threaded sleeves 501. The two sides of the bridge panel 200 are respectively in contact with the circumferential outer edges of the two first threaded sleeves 501. The axis of the first threaded sleeves 501 is perpendicular to the length direction of the first rotating rod 500. Locking assemblies are respectively disposed on both sides of the bridge panel 200. The locking assemblies include a first screw 502, which is threadedly connected to the first threaded sleeves 501 of the two bridge panels 200. Figure 7 As shown in (B).

[0071] When it is necessary to adjust the angle between two adjacent bridge panels 200, the first screw 502 is rotated so that it disengages from one of the first threaded sleeves 501, thereby enabling the relative rotation of the two bridge panels 200. After the two bridge panels 200 are rotated to the target angle, the first screwed sleeve 501 is rotated by the first rotating rod 500, thereby causing the two first threaded sleeves 501 at adjacent positions at the ends of the two bridge panels 200 to rotate to the coaxial line. Then, the first screw 502 is rotated in the opposite direction so that it passes through the two first threaded sleeves 501 on the coaxial line, thereby locking the relative angle of the two bridge panels 200.

[0072] When the relative angles of all adjacent bridge panels 200 are adjusted and locked in the manner described above, and when the two adjacent bridge panels 200 are locked onto the same plane, the panel assembly is in an unfolded state. In this state, the panel assembly takes the form of a long, strip-shaped plate structure, which has different functions depending on the usage scenario, such as... Figure 2As shown, when one of the bridge deck panels 200 at the end is connected to the end of the transport plate 101, it can be used as a ramp to facilitate the quick loading and unloading of the bridge pier boat 400 onto the transport plate 101 of the transport vehicle 100. Figure 3 As shown, the four bridge panels 200 can also be laid on the four bridge pier boats 400 in the river. When the two panel assemblies, a total of eight bridge panels 200, are laid on the four bridge pier boats 400, the bridge panels 200 at the end are connected to the ramps 300 to form two bridges for the transport vehicle 100 to pass through to overcome river obstacles. When two adjacent bridge panels 200 are close together and opposite each other, the panel assembly is in a folded state. At this time, the panel assembly can be installed on the transport plate 101, which, together with the cab 102 and the ramps 300 on both sides, surrounds the upper part of the four sides of the transport plate 101 to form a transport compartment with an open top. The transport compartment can hold four bridge pier boats 400, so that the transport vehicle 100 can carry the four bridge pier boats 400 safely to the river for bridge construction.

[0073] A further improvement is that a second threaded sleeve 601 is rotatably mounted on the side of the scaffold 300. The rotation axis of the second threaded sleeve 601 is parallel to the width direction of the scaffold 300, and the axis of rotation of the second threaded sleeve 601 is perpendicular to the rotation axis of the second threaded sleeve 601. The second threaded sleeve 601 is threadedly connected to a second screw 602, and the second threaded sleeve 601 is connected to the first threaded sleeve 501 or the transport plate 101 through the second screw 602.

[0074] In this invention, there are a total of four ramps 300. When the transport vehicle 100 is in motion, the four ramps 300 are respectively arranged in pairs on both sides of the transport plate 101. The structure of the ramps 300 is similar to that of the bridge deck 200. A second rotating rod 600 is sealed and penetrated at both ends of the ramp 300, so that the second rotating rod 600 can rotate around its own axis on the ramp 300. Two second threaded sleeves 601 are integrally formed at both ends of the second rotating rod 600. The two sides of the ramp 300 are respectively attached to the circumferential outer edge of the two second threaded sleeves 601. The axis of the second threaded sleeve 601 is perpendicular to the length direction of the second rotating rod 600. The second threaded sleeve 601 is threadedly connected to a second screw 602.

[0075] With the above structure, the ramp 300 can be connected to one of the transport plate 101 or the end bridge plate 200 as needed, such as... Figure 4 As shown, the transport plate 101 has mounting holes on its side. These mounting holes are through holes. When connecting the scaffold 300 to the transport plate 101, the second threaded sleeve 601 is aligned with the mounting hole. The second screw 602 is screwed into the mounting hole, and the second threaded sleeve 601 is screwed into the outside of the second screw 602, thus connecting the scaffold 300 and the transport plate. However, when connecting to the bridge deck 200 at the end, as... Figure 7As shown, the first screw sleeve 501 and the second screw sleeve 601 can be adjusted by the first rotating rod 500 and the second rotating rod 600 respectively, so that the first screw sleeve 501 and the second screw sleeve 601 are coaxial. Then, the second screw 602 is screwed in along the second screw sleeve 601, so that the second screw sleeve 601 passes through the first screw sleeve 501, thus realizing the connection between the scaffold 300 and the end of the panel assembly in the unfolded state. It should be noted that since the first rotating rod 500 and the second rotating rod 600 can both rotate 360° around their own axis, the rotation angle of the first screw sleeve 501 and the second screw sleeve 601 can be adjusted arbitrarily, and the second screw 602 is screwed in after they are kept coaxial. Therefore, when the scaffold 300 and the bridge panel 200 are connected to form a bridge, the angle between the scaffold 300 and the bridge panel 200 can be adjusted arbitrarily and fixed by the second screw 602.

[0076] To facilitate the smooth passage of the transport vehicle 100 over the ramp 300 and bridge deck 200 during bridge construction, anti-slip strips 210 are provided on one side of both the ramp 300 and the bridge deck 200 along their thickness direction, arranged side by side and adjacent to each other along the length of that side to increase surface roughness.

[0077] A further improvement is that a connector 103 is provided at the end of the transport plate 101 away from the cab 102. The connector 103 is provided with a first insertion hole 1031 and a second insertion hole 1032 distributed along a first direction and extending in a vertical direction. The first insertion hole 1031 is located between the second insertion hole 1032 and the transport plate 101. The first insertion hole 1031 is engaged with a first threaded sleeve 501 located at one end of the panel assembly through a fixed insertion rod 700. The second insertion hole 1032 is engaged with one of the first threaded sleeves 501 through a movable insertion rod 800. The fixed insertion rod 700 and the movable insertion rod 800 are threadedly connected by a third screw 900. A positioning frame 105 is provided on the transport plate 101, and the rod of the third screw 900 passes through the positioning frame 105.

[0078] Specifically, such as Figure 4 (C) Figure 5 (A) and Figure 6As shown in (B), two connectors 103 are provided on both sides of the panel assembly. The connectors 103 are welded and fixed to the end of the transport plate 101 away from the cab 102. The connectors 103 are provided with a first socket 1031 and three second sockets 1032. The first socket 1031 is located on the side of the three second sockets 1032 closer to the cab 102. The first socket 1031 and the three second sockets 1032 all extend in the vertical direction and are all through holes. The first socket 1031 is connected to one of the... The first threaded sleeve 501 corresponding to the bridge panel 200 at the end position is engaged with the fixed insert rod 700. The three second insert holes 1032 are engaged with the three first threaded sleeves 501 corresponding to the remaining three bridge panels 200 through three movable insert rods 800. The fixed insert rod 700 is integrally connected to the end of the fixed threaded sleeve 701. The ends of the three movable insert rods 800 are integrally connected through the movable threaded sleeves 801. Both the fixed threaded sleeve 701 and the movable threaded sleeve 801 are threadedly connected to the third screw 900.

[0079] With the above structure, when the four first threaded sleeves 501, the first insertion hole 1031, and the three second insertion holes 1032 are respectively connected by the fixed insertion rod 700 and the three movable insertion rods 800, the folded panel assembly can be fixed to the end of the transport plate 101 away from the cab 102. After the third screw 900 is unscrewed from the fixed threaded sleeve 701 and separated from the fixed threaded sleeve 701, the three movable insertion rods 800 can be removed from the three second insertion holes 1032 through the movable threaded sleeves 801. At this point, in the panel assembly, one of the bridge panels 200 located at the end is rotatably connected to the transport plate 101 via the first rotating rod 500. The tilt angle of this bridge panel 200 is adjusted, and the locking components of the two adjacent bridge panels 200 are released, allowing the four bridge panels 200 to rotate relative to each other. After the four bridge panels 200 are adjusted to the same plane, they are locked together by the first screw 502. The ends of the bridge panels 200 furthest from the transport plate 101 are then supported by the ground, forming a structure as shown in the image. Figure 2 and Figure 5 The ramp shown facilitates the loading and unloading of the four bridge foot boats 400 onto the transport plate 101; after removing the fixing rod 700, the bridge panel 200 at the end is separated from the transport plate 101, at which point the bridge panel 200 at both ends of the panel assembly in the unfolded state can be assembled and connected to the two ramps 300 respectively.

[0080] Two positioning frames 105 are respectively provided on both sides of the end of the transport plate 101 away from the cab 102. Each positioning frame 105 corresponds to one of the two panel assemblies. The positioning frame 105 is elongated, with threaded holes at both ends that mate with the third screw 900. The positioning frame 105 is rotatably connected to the transport plate 101 via a rotating seat 106, with the rotation center line parallel to the length direction of the transport plate 101. Figure 4As shown, when the positioning frame 105 rotates to be directly above the transport plate 101 and in contact with the transport plate 101, the third screw 900 is tightened so that the third screw 900 passes through the positioning frame 105, thereby fixing the fixed plug 700 and the movable plug 800 to the transport plate 101, preventing the fixed plug 700 and the movable plug 800 from detaching from the plug seat 103 due to vibration during the operation of the transport vehicle 100.

[0081] Understandably, the bridge deck panels 200 carried by two or more transport vehicles 100 can be spliced ​​together to increase the span of the pontoon bridge and enable it to cross wider rivers.

[0082] A further improvement is that the bridge pier boat 400 includes a bow boat 110 and a stern boat 120, which are rotatably connected. A locking assembly 130 is provided between the bow boat 110 and the stern boat 120 to lock them in an unfolding position and a folding position. In the folding position, the bow boat 110 and the stern boat 120 are adjacent to each other and their openings face each other. In the unfolding position, the bow boat 110 and the stern boat 120 are combined to form an assault boat. The locking assembly 130 includes... The locking bar 131, locking sleeve 132, and locking screw 133 are provided. The locking bar 131 is provided with a locking opening 134 extending along its own length direction. Of the bow boat 110 and stern boat 120, one is fixedly connected to the locking screw 133, and the other is rotatably connected to the locking bar 131 with the rotation axis perpendicular to the length direction of the locking bar 131. The locking screw 133 passes through the locking opening 134 and is threadedly connected to the locking sleeve 132.

[0083] Specifically, the pier boat 400 includes a bow boat 110 and a stern boat 120 rotatably connected, with the rotation axis parallel to the width direction of the pier boat 400. The bow boat 110 and the stern boat 120 are locked to two positions by locking components 130, as shown below. Figure 8 , Figure 8 (A) and Figure 8 (D) shows the unfolding station and as shown in the figure. Figure 8 (E) shows the folding station.

[0084] Furthermore, the bow 110 and stern 120 are integrally connected on both sides of the top of their adjacent ends with collars 260 extending along their width direction. The stern 120 and bow 110 are integrally connected on both sides of the top of their adjacent ends with rotating shafts 261 extending along their width direction. The outer circumferential edge of the rotating shaft 261 is sealed to the inner circumferential wall of the collar 260. The rotating connection between the bow 110 and stern 120 is achieved through the rotational engagement of the rotating shaft 261 and the collar 260.

[0085] The bow 110 is fixed with convex shafts 250 on both sides. The outer sealing sleeve of the convex shaft 250 is provided with a locking strip 131, which allows the locking strip 131 to rotate around the convex shaft 250. The end of the locking strip 131 away from the convex shaft 250 is provided with a locking opening 134 extending along its own length direction. The stern 120 is fixed with locking screws 133 on both sides. The locking screws 133 pass through the locking opening 134, pass through the locking strip 131, and are threadedly connected to the locking sleeve 132, so as to lock the bow 110 and the stern 120 in the folding position and the unfolding position.

[0086] When the bow boat 110 and stern boat 120 are locked in the folding position, the length of the bridge foot boat 400 is reduced. The openings of the bow boat 110 and stern boat 120 are aligned, allowing the bridge foot boat 400 to be placed vertically on the transport plate 101, reducing the overall height of the device and decreasing the wind resistance encountered by the transport vehicle 100. When the bow boat 110 and stern boat 120 are locked in the unfolding position, their lengths are aligned. At this time, the bow boat 110 and stern boat 120 have two functions: firstly, they are used as assault boats, and secondly, they support the bridge deck 200 on the water. The bow boat 110 and stern boat 120 of the four bridge foot boats 400 support the bridge deck 200 of the two panel assemblies respectively. The bridge deck 200 at the ends is connected to the ramp 300 to form a bridge. The bridge allows the transport vehicle 100 itself and other light equipment and vehicles to pass through, enabling the above-mentioned transport device to easily overcome river obstacles.

[0087] Both the bow boat 110 and the stern boat 120 have grooves extending along their length at their bottoms. Rollers 270 are installed in the grooves and protrude from the bottom surface of the bow boat 110 (or stern boat 120). The rollers 270 facilitate the movement of the bridge foot boat 400 after it is laid flat. This makes it easy to quickly load and unload the bridge foot boat 400 onto the transport vehicle 100 via the ramp formed by the panel assembly.

[0088] A further improvement is that both the bow boat 110 and the stern boat 120 include an upper boat body 150 and a lower boat body 160. The upper boat body 150 has a downward-facing, closed-loop positioning sleeve 151. The upper boat body 150 is sealed and fitted onto the upper part of the lower boat body 160 through the positioning sleeve 151. An elastic sealing sleeve 170 is provided between the inner wall of the positioning sleeve 151 and the top of the lower boat body 160. A telescopic unit 180 is provided between the upper boat body 150 and the lower boat body 160 to drive them to slide relative to each other along the height direction of the bridge pier boat 400.

[0089] Specifically, such as Figure 9 and Figure 10As shown, both the bow boat 110 and the stern boat 120 include an upper boat body 150 and a lower boat body 160 arranged along their own height direction. The upper boat body 150 is sealed to the circumferential side wall of the lower boat body 160 through a downward positioning sleeve 151, and the two are slidably connected relative to each other along the height direction of the bridge pier boat 400 through a telescopic unit 180. A sealing sleeve 170 is provided in the positioning sleeve 151. The sealing sleeve 170 is a rubber sleeve, and its two end faces are connected to the upper boat body 150 and the lower boat body 160 respectively. The telescopic unit 180 is preferably an electric push rod. Its housing is fixedly connected to the lower boat body 160, and the telescopic rod is fixedly connected to the upper boat body 150.

[0090] When the bow boat 110 and stern boat 120 are in the folding position, the telescopic unit 180 drives the upper boat 150 and lower boat 160 to move closer together to reduce the height of the bridge foot boat 400, thereby reducing its size and making it easier to store the bridge foot boat 400 on the transport plate 101. When the bow boat 110 and stern boat 120 are in the unfolding position, the telescopic unit 180 drives the upper boat 150 and lower boat 160 to move away from each other to increase the height of the bridge foot boat 400. This increases the load capacity of the bridge foot boat 400 by enlarging its size, allowing the bridge formed by the panel assembly and the ramp 300 to withstand more weight. At the same time, it increases the load capacity of the bridge foot boat 400 when used as an assault boat, thereby improving transportation efficiency.

[0091] By installing a sealing sleeve 170 between the upper hull 150 and the lower hull 160, water can be prevented from entering the gantry boat 400. The upper hull 150 and the lower hull 160 are made of sturdy aluminum alloy. Compared with setting airbags on the outside of the assault boat to increase the load capacity, in this invention, by increasing the distance between the upper hull 150 and the lower hull 160, the size and load capacity of the gantry boat 400 are increased, and the sealing sleeve 170 is used to achieve waterproof sealing. The sealing sleeve 170 is located inside the positioning sleeve opening 151. In this way, the sealing sleeve 170 is protected by the upper hull 150 and avoids wear, thereby ensuring the safe use of the gantry boat 400.

[0092] A further improvement is that one side of the bridge deck 200 is provided with two positioning slots 201 extending along its width and arranged side by side, and the bridge pier boat 400 is fixed with a positioning protrusion 140 arranged along its length. When the bridge deck 200 is laid on the bridge pier boat 400, the bridge pier boat 400 and the bridge deck 200 are connected and engaged through the two positioning slots 201 and the positioning protrusion 140.

[0093] Specifically, the two positioning protrusions 140 are respectively fixed between the two inner sidewalls of the top of the upper boat body 150. With the above structure, as shown... Figure 7As shown in (A), when the bridge deck 200 is laid on the upper boat 150 of the bridge foot boat 400, two positioning slots 201 are respectively fitted onto the top of the two opposite side walls of the upper boat 150, and two positioning protrusions 140 are respectively clamped on both sides of the bridge deck 200, so that the bridge deck 200 cannot move horizontally, thereby stabilizing the position of the bridge deck 200. After the bridge is erected, the transport vehicle 100 can pass smoothly over the bridge deck 200. When disassembling, the bridge deck 200 only needs to be lifted upwards, so that the positioning slots 201 are disengaged from the upper boat 150 and the bridge deck 200 is disengaged from the two positioning protrusions 140, and the bridge deck 200 can be removed, making the bridge erection and unloading quick and convenient.

[0094] A further improvement is that the bridge pier 400 is threadedly connected to the watercraft 190 via the fourth screw 191. The watercraft 190 has a storage position and a navigation position. In the storage position, the watercraft 190 is fixed between the bow 110 and the stern 120 in the folding position. In the navigation position, the watercraft 190 is fixed to the end of the bow 110 away from the stern 120.

[0095] Specifically, a first screw tube 230 is fixed to the inner bottom wall of the hull 160 under the stern boat 120. The first screw tube 230 is threadedly connected to the fourth screw 191 to fix the watercraft 190 inside the stern boat 120. Then, the bow boat 110 is rotated so that the watercraft 190 is positioned between the bow boat 110 and the stern boat 120 at the folding position. In this state, the watercraft 190 is fixed inside the pier boat 400. The watercraft 190 is transported simultaneously with the pier boat 400. Since the watercraft 190 is fixed inside the pier boat 400 by the fourth screw 191, the transport vehicle is prevented from being moved during transportation. The vibration caused the watercraft 190 and the pontoon 400 to collide and both were damaged. Meanwhile, a mounting plate 240 is fixed to the end of the hull 150 of the stern boat 120 away from the pivot 261. A second screw tube 241 is provided on the mounting plate 240 and is threadedly connected to a fourth screw 191 to fix the watercraft 190 to the mounting plate 240. In this state, the watercraft 190 is located at the end of the stern boat 120 away from the bow boat 110 in the deployment position. The watercraft 190 can provide the power for the pontoon 400 to navigate on the water, meeting the needs of the pontoon 400 to be used as an assault boat.
