Description

Technical Field

[0001] This utility model relates to the field of water engineering technology, and in particular to a detachable temporary construction pontoon base for a river crossing truss. Background Technology

[0002] The temporary floating pontoon base for river-crossing trusses is a temporary floating support platform used in construction scenarios in rivers, lakes, or other water bodies. It mainly consists of pontoons and splicing mechanisms, and provides support through the buoyancy of the pontoons to support river-crossing trusses or other construction equipment.

[0003] In existing pontoon base construction, multiple pontoons are usually spliced ​​together by using pins for fixing. However, this fixing method has the following problems: when it is necessary to separate the pontoons, the pins usually need to be pulled out with the help of external tools (such as wrenches, pry bars, etc.), which makes it impossible to quickly complete the splicing and disassembly, thus reducing construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a detachable temporary construction pontoon base for river crossing trusses in order to solve the problem of the inability to quickly complete the splicing and disassembly of pontoons.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A detachable temporary construction pontoon base for a river crossing truss includes pontoons and a splicing mechanism for connecting several pontoons together.

[0007] The splicing mechanism includes extension plates fixedly installed at the four corners of the pontoon. Insert rods are inserted into the interior of the extension plates. A connecting component for fixing the insert rods is mounted on the bottom extension plate. A locking component for fixing the spliced ​​pontoon is also mounted on the connecting component.

[0008] During assembly, the insert rods and connecting components work together to achieve locking and fixation. The extension plates are staggered and fitted onto the insert rods, and the locking components complete the rapid locking and separation of the pontoons. This solution, through the mechanical linkage design of the assembly mechanism, allows for efficient assembly and disassembly without external tools. It is suitable for the construction of pontoon bases for temporary construction of trusses across rivers, lakes, and other water bodies, significantly improving construction efficiency and ease of operation.

[0009] As a further description of the above technical solution:

[0010] The connecting component includes several slots formed on the bottom extension plate, and the slots have locking blocks inside.

[0011] As a further description of the above technical solution:

[0012] The card block is fixedly installed on the insertion rod, and a channel of the same size as the card block is opened on one side of the card slot. A rubber pad is fixedly installed at the bottom of the card block.

[0013] As a further description of the above technical solution:

[0014] The engaging assembly includes a ring fixedly mounted on the insert rod, a sleeve sleeved on the insert rod, a slider slidably connected to the outer wall of the sleeve, a spring fixedly installed between the sleeve and the slider, and several sliding grooves opened inside the sleeve, with limit blocks slidably connected to the sliding grooves.

[0015] As a further description of the above technical solution:

[0016] The two ends of the slide are connected to the sleeve, the two ends of the limiting block are set as arc surfaces, and the bottom end of the slider is provided with a groove.

[0017] As a further description of the above technical solution:

[0018] The top of the pontoon has several rectangular slots, and the inside of the pontoon has a cavity. Water inlets are provided around the cavity and at the bottom.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] This technical solution achieves locking and fixing through the cooperation of insert rods and connecting components. Extension plates are staggered and fitted onto the insert rods, and the locking components enable rapid locking and disengagement of the pontoons. This solution, through the mechanical linkage design of the splicing mechanism, allows for efficient assembly and disassembly without external tools. It is suitable for the construction of pontoon bases for temporary truss construction in rivers, lakes, and other water bodies, significantly improving construction efficiency and ease of operation.

[0021] During assembly, simply rotate the insert rod to fix the locking block and the slot. Then, combine several floats together so that the extension plates on the floats are staggered and fitted onto the insert rod. Through the design of the locking component, when the sleeve is fitted onto the insert rod, the sliding block can quickly limit the insertion rod by moving the slider, thereby fixing the floats together and realizing the automatic limiting and unlocking functions.

[0022] The hollow design inside the buoy allows water to enter through the inlet, thereby adjusting the weight of the buoy and improving its stability in the water. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figure 1 - Figure 8 As shown, the present invention provides a detachable temporary construction pontoon base for a river crossing truss, including pontoons 10 and a splicing mechanism 20 for splicing several pontoons 10 together.

[0036] The splicing mechanism 20 includes extension plates 21 fixedly installed at the four corners of the pontoon 10. Insert rods 22 are inserted into the inside of the extension plates 21. A connecting component 23 that can fix the insert rods 22 is mounted on the bottom extension plate 21. A locking component 24 that can fix the spliced ​​pontoon 10 is also mounted on the connecting component 23.

[0037] like Figure 4 - Figure 5 As shown, the connecting component 23 includes several slots 231 formed on the bottom extension plate 21, and the slots 231 have locking blocks 232 inside.

[0038] In more detail, the locking block 232 is fixedly installed on the insert rod 22. A channel of the same size as the locking block 232 is provided on one side of the locking groove 231, allowing the locking block 232 to move out of the groove 231. A rubber pad is fixedly installed at the bottom of the locking block 232, increasing the friction between the groove 231 and the locking block 232. In use, the floats 10 floating on the water surface are assembled, and then the insert rod 22 is inserted into the locking block 232 with the groove 231, so that the locking block 232 is located in the channel of the groove 231. Then, by rotating the insert rod 22, the locking block 232 rotates and engages with the groove 231. The rubber pad, deformed by pressure, increases the friction between the locking block 232 and the groove 231, preventing the locking block 232 from accidentally disengaging from the groove 231. Then, several floats 10 are combined, such as... Figure 1 As shown, the extension plates 21 on several floats 10 are arranged in an alternating manner and fitted onto the insert rods 22.

[0039] like Figure 5 - Figure 7 As shown, the engaging assembly 24 includes a ring 241 fixedly mounted on the insert rod 22, a sleeve 242 sleeved on the insert rod 22, a slider 243 slidably connected to the outer wall of the sleeve 242, a spring 244 fixedly installed between the sleeve 242 and the slider 243, and the sleeve 242 can be reset by the reaction force of the spring 244. Several sliding grooves 245 are opened inside the sleeve 242, and the sliding grooves 245 are slidably connected to limit blocks 246, which can move within the sliding grooves 245.

[0040] In more detail, the two ends of the slide groove 245 are connected to the sleeve 242, and the two ends of the limiting block 246 can extend out from the slide groove 245. The two ends of the limiting block 246 are set as arc surfaces, and the bottom end of the slider 243 has a groove. After several extension plates 21 are sleeved on the insertion rod 22, the sleeve 242 is then inserted into the insertion rod 22. At the same time as insertion, the slider 243 is pulled upward so that the slider 243 no longer squeezes the limiting block 246. At this time, the limiting block 246 and the groove are closed. Correspondingly, as the sleeve 242 moves down, one end of the limiting block 246 will contact the top of the ring 241. At this time, the limiting block 246 will be squeezed by the ring 241 through the arc surface design, causing the limiting block 246 to move in the slide groove 245, so that the other end of the limiting block 246 extends to the groove. When the sleeve 242 stops moving, the bottom end of the sleeve 242 contacts the topmost extension plate 21, while the limiting block 246 is located at the bottom of the ring 241.

[0041] Next, the sleeve 242 is released, and the sleeve 242 is lowered and reset by the reaction force of the spring 244. At the same time as it is lowered, one end of the limiting block 246 at the groove is squeezed, causing the limiting block 246 to move again. This causes the other end of the limiting block 246 to extend and be located at the bottom of the ring 241 for limiting, thereby limiting the several extension plates 21 together.

[0042] In more detail, the top of the float 10 has several rectangular grooves, which serve as an anti-slip feature. The float 10 has an internal cavity with water inlets at its perimeter and bottom. When the float 10 is placed on the water surface, water enters the cavity through these inlets, increasing its weight and improving its stability on the water surface. After the floats 10 are assembled, as... Figure 8 As shown, the river-crossing truss is then spliced ​​together with the pontoon 10 using clips.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
