Description

A quick-installation structure for Bailey panels Technical Field

[0001] This utility model relates to the field of Bailey bridges, specifically to a quick-installation structure for Bailey panels. Background Technology

[0002] Bailey bridge panels, also known as Bailey trusses, Bailey beams, or trusses, were first invented during World War II by a British engineer to address the need for rapid bridge erection during the war, and were named after him. They can be used in highway bridges, assembling gantry cranes, guide beams, bridge erecting machines, suspended platforms, etc.

[0003] Bailey panels are installed by connecting them end to end. During the installation process, it is often difficult to align the pin holes at both ends of the Bailey panel, which affects the installation efficiency. Therefore, a quick installation structure is needed to solve this problem. Summary of the Invention

[0004] This utility model aims to solve the technical problems mentioned in the background section above, and proposes the following technical solutions:

[0005] A quick-installation structure for a Bailey bridge includes a Bailey bridge and a connecting structure. The Bailey bridge includes a vertical rod, a chord rod, and a diagonal rod. The chord rod is further divided into an upper chord rod and a lower chord rod. Slots and inserts are respectively provided on the left and right sides of the chord rod. The slots and inserts are respectively provided with a first fixing pin hole and a second fixing pin hole at corresponding positions. A fixing groove is provided on one side above the upper chord rod, and a fixing rod is provided in the fixing groove. A sliding groove is provided on the other side above the upper chord rod. Limiting blocks are symmetrically provided on both sides of the inner wall of the sliding groove. A rack is fixedly provided at the bottom of the sliding groove. The connecting structure is located on the sliding groove.

[0006] The connecting structure includes a base, a connecting rod, a rotating shaft, two rotating shaft seats, two sliders, a gear, and a handle. The sliders are located at the bottom of the base and within the sliding groove. A limiting groove is provided on one side of the slider, and a limiting block is slidably connected to the limiting groove. A gear groove is provided at the bottom of the base, and a gear is located within the gear groove, meshing with a rack. A handle insertion hole is provided on the side of the base, through which the handle passes and connects to the gear. The rotating shaft seats are mounted on the base, and both ends of the rotating shaft are rotatably connected to the two rotating shaft seats respectively. One end of the connecting rod is fixedly sleeved on the outside of the rotating shaft, and the other end of the connecting rod has a bent structure.

[0007] Preferably, the inner side of the connecting rod is a semi-circular structure and its size corresponds to that of the fixing rod.

[0008] Preferably, one end of the insert has an arc-shaped structure.

[0009] Preferably, the insert has a structure with a small front end and a large rear end.

[0010] Limited, there is a gap between one end of the limiting block and the same end of the slide groove, and the base can pass through the gap.

[0011] The beneficial effects of this utility model are:

[0012] 1. By setting up a connecting structure, two Bailey panels are connected through the connecting structure. The connecting structure can be moved by the movable base, so that the two Bailey panels can move closer to each other synchronously along the direction of the connecting rod on the connecting structure, without the need for alignment work.

[0013] 2. By setting one end of the plug to be an arc-shaped mechanism, it is easier for the plug to fit into the slot.

[0014] 3. By setting a gap between one end of the limiting block and the same end of the slide, and allowing the base to pass through the gap, the operator can remove the connecting structure from the Bailey plate through the gap, making it convenient to reuse the connecting structure multiple times.

[0022] Example 1

[0023] Referring to Figures 1-3, a quick-installation structure for a Bailey bridge includes a Bailey bridge 1 and a connecting structure 2. The Bailey bridge 1 includes a vertical rod 1-1, a chord rod 1-2, and a diagonal rod 1-3. The chord rod 1-2 is further divided into an upper chord rod 1-21 and a lower chord rod 1-22. Slots 3 and inserts 4 are respectively provided on the left and right sides of the chord rod 1-2. The slots 3 and inserts 4 are respectively provided with a first fixing pin hole 3-1 and a second fixing pin hole 4-1 at corresponding positions. A fixing groove 5 is provided on one side above the upper chord rod 1-21. A fixing rod 6 is provided in the fixing groove 5. A sliding groove 7 is provided on the other side above the upper chord rod 1-21. Limiting blocks 8 are symmetrically provided on both sides of the inner wall of the sliding groove 7. A rack 9 is fixedly provided at the bottom of the sliding groove 7. The connecting structure 2 is located on the sliding groove 7.

[0024] The connecting structure 2 includes a base 2-1, a connecting rod 2-2, a rotating shaft 2-3, two rotating shaft seats 2-4, two sliders 2-5, a gear 2-6, and a handle 2-7. The slider 2-5 is located at the bottom of the base 2-1 and is located in the slide groove 7. A limiting slide groove 2-51 is provided on one side of the slider 2-5, and the limiting block 8 is slidably connected to the limiting slide groove 2-51. A gear groove 2-11 is provided at the bottom of the base 2-1, and the gear 2-6 is located in the gear groove 2-11 and meshes with the rack 9. A handle insertion hole 2-12 is provided on the side of the base 2-1, and the handle 2-7 passes through the handle insertion hole 2-12 and is connected to the gear 2-6. The rotating shaft seat 2-4 is installed on the base 2-1, and both ends of the rotating shaft 2-3 are rotatably connected to the two rotating shaft seats 2-4 respectively. One end of the connecting rod 2-2 is fixedly sleeved on the outside of the rotating shaft 2-3, and the other end of the connecting rod 2-2 is a bent structure.

[0025] Preferably, the inner side of the connecting rod 2-2 is a semi-circular structure and its size corresponds to that of the fixed rod 6.

[0026] Preferably, one end of the insert 4 has an arc-shaped structure.

[0027] Preferably, the insert 4 has a structure with a small front end and a large back end.

[0028] In actual operation, the operator first moves the connecting structure 2 of Bailey piece B to the far left, then inserts the front end of the connecting rod 2-2 into the fixing groove 5 of Bailey piece A, hooks the bent area onto the fixing rod, and then rotates the handle 2-7. When the handle 2-7 rotates, it synchronously drives the gear 2-6 to rotate. Because the gear 2-6 meshes with the rack 9, when the gear 2-6 rotates, the base 2-1 will move along the direction of the rack 9. At this time, the connecting structure gradually moves to the right, and the two Bailey pieces gradually move closer until the inserts 4 on the two Bailey pieces are inserted into the slots 3. Then, the positions are aligned and the first fixing pin hole 3-1 and the second fixing pin hole 4-1 are connected in series. At this time, the connection is completed. Using this connection method, there is no need to align the inserts 4 and the slots 3, making the connection of the two Bailey pieces more convenient and faster.

[0029] Example 2

[0030] Referring to Figure 3, the difference between this embodiment and the first embodiment is that there is a gap between one end of the limiting block 8 and the same end of the slide groove 7, and the base 2-1 can pass through the gap. The operator can remove the connecting structure from the Bailey piece through the gap, which makes it convenient to use the connecting structure multiple times and avoids the problem that each Bailey piece needs to be equipped with a connecting structure.
