Description
Technical Field
[0001] This utility model relates to the field of building equipment technology, and in particular to a Bailey pin dismantling device. Background Technology
[0002] Bailey bridges are a common type of prefabricated building equipment structure, typically composed of several units that can be assembled into various components and equipment. Bailey pins are used to connect the units of the Bailey bridge; these pins are inserted into the male and female connectors of the unit structure to connect multiple units. After completion, disassembly is usually done by striking the Bailey pins, using tools such as hammers to tap the pins at their installation locations to slowly loosen them, often with the aid of pry bars and wrenches. Due to the weight of the Bailey bridge, the pins are subjected to significant shearing forces. This disassembly method requires considerable force, making removal very difficult. Furthermore, using hammers, pry bars, and wrenches is not only inefficient but also easily damages the pins, causing them to bend and become unusable. Additionally, it poses a safety risk, as auxiliary tools are difficult to secure, increasing the possibility of accidents. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0018] See Figure 1 and Figure 2 This utility model embodiment discloses a Bailey pin 4 disassembly device for disassembling Bailey pin 4 on Bailey frame 5. Specifically, it includes a fixed frame 1, a fixing mechanism 2 provided on the fixed frame 1, and a disassembly mechanism 3 connected to the fixing mechanism 2. The fixed frame 1 is used to support the fixing mechanism 2 and the disassembly mechanism 3. The fixed frame 1 is provided with a sliding channel 11, and the fixing mechanism 2 can slide in the sliding channel 11.
[0019] To connect the Bailey pin 4, the fixing mechanism 2 includes a connecting seat 21, which can be connected to the Bailey pin 4. The connection method can be a snap-fit, requiring no fixing, and the connection operation is simple. The disassembly mechanism 3 includes a connecting rod 31, one end of which is movably connected to the connecting seat 21. The connecting rod 31 can rotate to drive the connecting seat 21 to slide within the sliding channel 11. Tools such as pneumatic screwdrivers and electric screwdrivers can be used to drive the connecting rod 31 to rotate, avoiding manual disassembly and making disassembly simple, labor-saving, and time-saving. During the rotation of the connecting rod 31, the connecting seat 21 can be moved, and the movement of the connecting seat 21 can move the Bailey pin 4, thereby pulling out the Bailey pin 4 and achieving the purpose of quick removal.
[0020] The beneficial effects of this utility model embodiment are as follows:
[0021] This utility model embodiment of the Bailey pin 4 disassembly device includes a fixing frame 1, a fixing mechanism 2, and a disassembly mechanism 3. The fixing frame 1 is provided with a sliding channel 11. The fixing mechanism 2 includes a connecting seat 21, which can be connected to the Bailey pin 4. The disassembly mechanism 3 includes a connecting rod 31, one end of which is movably connected to the connecting seat 21. The connecting rod 31 can rotate to drive the connecting seat 21 to slide within the sliding channel 11. During disassembly, the connecting seat 21 is first connected to the Bailey pin 4. Then, a power tool is used to drive the connecting rod 31 to rotate, thereby driving the connecting seat 21 to slide within the sliding channel 11. When the connecting seat 21 moves, the Bailey pin 4 can be pulled out, thereby achieving the effect of quickly removing the Bailey pin 4. At the same time, no heavy hammer or other tools are needed, which reduces the difficulty and labor intensity of disassembly, and will not damage the Bailey pin 4. Moreover, the disassembly is simple and can improve construction safety.
[0022] Specifically, the fixing frame 1 further includes a first side plate 12 and a second side plate 13. The first side plate 12 and the second side plate 13 are arranged in parallel. The first side plate 12 and the second side plate 13 can form the sliding channel 11. The connecting seat 21 can slide within the sliding channel 11. The sliding channel 11 limits the movement direction of the connecting seat 21, so that the connecting seat 21 can be removed along the disassembly direction of the Bailey pin 4.
[0023] The connecting seat 21 includes a locking plate 211 and an abutment plate 212. The locking plate 211 can be connected to the Bailey pin 4, and the abutment plates 212 are disposed on both sides of the locking plate 211. The abutment plates 212 on both sides are arranged parallel to each other and can respectively abut against the inner sides of the first side plate 12 and the second side plate 13. The locking plate 211 can be locked with the Bailey pin 4, which is simple to connect, easy to disassemble, and reusable. The first side plate 12 and the second side plate 13 can respectively limit the movement of the abutment plates 212 on both sides to ensure the direction of movement of the connecting seat 21.
[0024] Furthermore, the positioning plate 211 is provided with a positioning groove 213, which is a U-shaped groove with the opening facing the outside of the positioning plate 211. The fixing mechanism 2 also includes a disassembly bolt 22. The outer end face of the Bailey pin 4 is provided with a connecting hole 41, which is a countersunk hole with threads on the inner wall. One end of the disassembly bolt 22 can be screwed into the connecting hole 41 to form a fixed connection, and the other end of the disassembly bolt 22 can be inserted into the positioning groove 213. Since the positioning groove 213 is a U-shaped groove with the opening facing the outside of the positioning plate 211, the disassembly bolt 22 can be easily inserted into the positioning groove 213. The head of the disassembly bolt 22 can be engaged in the positioning groove 213 to form a detachable connection. The connection is simple and convenient, which can shorten the construction time.
[0025] Furthermore, the fixing frame 1 also includes a fixing plate 14, which is connected between the first side plate 12 and the second side plate 13. The connecting rod 31 passes through the fixing plate 14 and is connected to the connecting seat 21. The fixing plate 14 can limit the movement direction of the connecting rod 31. The fixing mechanism 2 also includes a connecting nut 23, which is fixed to the fixing plate 14. The inner side of the connecting nut 23 is threaded, and the outer side of the connecting rod 31 is threaded. The connecting rod 31 can be screwed into or out of the connecting nut 23. When the connecting rod 31 is driven to rotate, due to the meshing action between the connecting rod 31 and the connecting nut 23, the connecting rod 31 can extend or retract relative to the connecting nut 23. During the extension process, it can drive the connecting seat 21 to pull out the Bailey pin 4, and during the retraction process, it can drive the connecting seat 21 to move closer to the Bailey pin 4, so that the connecting seat 21 can be connected to the disassembly bolt 22.
[0026] The connecting seat 21 further includes a connecting plate 214, which is disposed between the two abutting plates 212. The connecting plate 214 has a movable hole. The end of the connecting rod 31 away from the connecting nut 23 is provided with a limiting block 32. The end of the connecting rod 31 away from the connecting nut 23 can pass through the movable hole and connect with the limiting hole. The connecting rod 31 can rotate within the movable hole, so that the connecting seat 21 does not affect the rotation of the connecting rod 31, while connecting the connecting rod 31 to the connecting seat 21.
[0027] In addition, the first side plate 12 and / or the second side plate 13 are provided with a positioning rod 15. The positioning rod 15 extends from the end of the first side plate 12 and / or the second side plate 13 away from the positioning plate and forms an L-shape. When using the Bailey pin 4 disassembly device, the positioning plate can abut against the side of the Bailey frame 5 to form a positioning, which facilitates the connection of the connecting seat 21 and the disassembly bolt 22.
[0028] Before disassembling the Bailey pin 4, first screw the disassembly bolt 22 into the Bailey pin 4. During disassembly, use a power tool to drive the connecting rod 31 to rotate. The connecting rod 31 can drive the connecting seat 21 to approach the Bailey pin 4. Then, using the locking groove 213, insert the head of the disassembly bolt 22 into the locking groove 213, so that the connecting seat 21 and the Bailey pin 4 are connected. Then, use a power tool to drive the connecting rod 31 to rotate in the opposite direction. The connecting rod 31 gradually extends and drives the connecting seat 21 to move. The connecting seat 21 drives the Bailey pin 4 to be pulled out from the male and female ends of the Bailey frame 5 through the disassembly bolt 22, thereby completing the disassembly.
[0029] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
