Description

A guide frame for connecting Bailey panels Technical Field

[0001] This utility model relates to the field of steel frame bridges, specifically to a guide frame for connecting Bailey bridge sections. Background Technology

[0002] Bailey panels are modular, rapidly assembled steel truss units widely used in bridges, temporary structures, military engineering, and disaster relief. Their design concept originated during World War II and was invented by British engineer Donald Bailey to address the need for rapid bridge construction in wartime. In modern times, they are commonly found in military bridges, disaster relief bridges, and mountain bridges.

[0003] When constructing a Bailey bridge, the only requirement is to assemble the Bailey panels. For bridges with shorter spans, trusses are typically erected on the riverbank first, and then the Bailey panels are assembled one by one. The assembly process can be carried out manually or by crane. During the assembly process, it is often necessary to align the connecting structures of two Bailey panels and adjust their positions. This requires manual labor. Solving this problem can greatly improve the efficiency of the assembly process. 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 guide frame for connecting Bailey panels includes a guide frame and a movable slide rail structure. The guide frame includes a base plate and a side plate. The side plate is installed on one side of the base plate. A first slide groove is provided on the base plate. The slide rail structure is located in the first slide groove. The slide rail structure includes a bottom slider and a Bailey panel placement seat. The bottom slider is slidably connected to the first slide groove. The Bailey panel placement seat is installed on the bottom slider. A Bailey panel placement slot is provided at the upper center of the Bailey panel placement seat.

[0006] The top of the side plate is provided with a second sliding groove, and a sliding base is slidably connected in the second sliding groove. A connecting bracket is provided on the sliding base, and a first threaded hole is provided on the connecting bracket. A positioning screw is threadedly connected in the first threaded hole, and a Bailey plate fixing block is connected to the bottom of the positioning screw. The Bailey plate fixing block is rotatably connected to the bottom of the screw.

[0007] Preferably, the Bailey plate fixing block is located directly above the Bailey plate placement seat, and the Bailey plate fixing block has a fixing groove in the middle.

[0008] Preferably, several connecting structures are provided on the left and right sides of the guide frame, and multiple guide frames can be connected end to end through the connecting structures.

[0009] Preferably, the side of the Bailey plate placement seat is provided with a second threaded hole, and a fixing screw is threaded into the second threaded hole. A fixing block is connected to the front end of the fixing screw, and the fixing block is located in the Bailey plate placement groove.

[0010] Preferably, a rubber pad is provided on one side of the fixing block.

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

[0012] 1. By setting up a guide frame and a movable slide rail structure on the guide frame, the Bailey panels can be placed on the movable slide rail structure for directional movement. This method not only solves the labor cost problem caused by manual handling, but also enables quick positioning and facilitates the connection of two Bailey panels.

[0013] 2. By setting multiple connecting structures on both sides of the guide frame, the two guide frames can be connected end to end, solving the problem that the length of one guide frame is insufficient when the bridge span is large.

[0014] 3. By setting a fixing block on the Bailey plate placement seat, and the fixing block can be moved by a fixing screw, the Bailey plate can be fixed on the Bailey plate placement seat by the fixing block, thus solving the problem of lateral movement of the Bailey plate during movement.

[0023] Example 1

[0024] Referring to Figure 1, a guide frame for connecting Bailey panels includes a guide frame 1 and a movable slide rail structure 2. The guide frame 1 includes a base plate 1-1 and a side plate 1-2. The side plate 1-2 is installed on one side of the base plate 1-1. A first slide groove 3 is provided on the base plate 1-1. The slide rail structure 2 is located in the first slide groove 3. The slide rail structure 2 includes a bottom slider 2-1 and a Bailey panel placement seat 2-2. The bottom slider 2-1 is slidably connected to the first slide groove 3. The Bailey panel placement seat 2-2 is installed on the bottom slider 2-1. A Bailey panel placement groove 2-3 is provided at the middle position above the Bailey panel placement seat 2-2.

[0025] A second sliding groove 4 is provided at the top of the side plate 1-2. A sliding base 5 is slidably connected in the second sliding groove 4. A connecting bracket 6 is provided on the sliding base 5. A first threaded hole 6-1 is provided on the connecting bracket 6. A positioning screw 7 is internally threaded in the first threaded hole 6-1. A Bailey plate fixing block 8 is connected to the bottom of the positioning screw 7. The Bailey plate fixing block 8 is rotatably connected to the bottom of the screw 7.

[0026] Preferably, the Bailey plate fixing block 8 is located directly above the Bailey plate placement seat 2-2, and the Bailey plate fixing block 8 has a fixing slot 8-1 in the middle.

[0027] In actual operation, before assembling the Bailey panels, the first Bailey panel is installed and fixed. Then, the guide frame 1 is set up on the installation path of the Bailey panel, and the position of the first slide groove 3 is aligned with the first Bailey panel. When installing the Bailey panel, the worker can first place the Bailey panel in the Bailey panel placement groove 2-3 on the Bailey panel placement seat 2-2, and then rotate the positioning screw 7 clockwise to lower the Bailey panel fixing block 8 until the fixing groove 8-1 locks the Bailey panel in place. Then, the Bailey panel can be pushed to move along the direction of the first slide groove 3 and the second slide groove 4 towards the direction of the first Bailey panel. During the movement, positioning can be quickly achieved, and the connection structure between the two Bailey panels is aligned, facilitating quick installation. After installation, rotate the positioning screw 7 counterclockwise to raise the fixing block 8, releasing the Bailey panel from the clamping state of the fixing block 8 and the Bailey panel placement seat 2-2. Then, the moving slide rail structure can be removed from the bottom of the Bailey panel to continue the installation of the next Bailey panel.

[0028] Example 2

[0029] Referring to Figure 2, the difference between this embodiment and Embodiment 1 is that a set of connecting structures 1-3 are respectively provided on the left and right sides of the guide frame 1. The connecting structures 1-3 are a combination of connecting slots and connecting columns. The guide frame 1 can connect the head and tail of multiple guide frames 1 through the connecting structures, which can solve the problem of insufficient length of guide frame 1 when the bridge span is large.

[0030] Example 3

[0031] Referring to Figures 3-4, the difference between this embodiment and Embodiment 1 is that a second threaded hole 9 is provided on the side of the Bailey panel placement seat 2-2. A fixing screw 10 is connected to the internal thread of the second threaded hole 9. The front end of the fixing screw 10 is connected to a fixing block 11. The fixing block 11 is located in the Bailey panel placement groove 2-3. A rubber pad 12 is provided on one side of the fixing block 11. The fixing block can fix the Bailey panel placed on the Bailey panel placement seat 2-2, preventing left and right movement during movement and deviation of the installation structure position of the front and rear Bailey panels. This solves the problem that the position of the Bailey panels needs to be adjusted to align the connection structure when connecting the Bailey panels.
