[0001] The present invention relates to the technical field of Bailey truss lapping, and specifically to a correction mechanism for rapid lapping of Bailey trusses and a method for rapid lapping of Bailey trusses. Background Art
[0002] A Bailey truss is a steel frame forming a certain unit, and it can be spliced and assembled into many components and equipment; due to its simple structure, convenient assembly, wide application range and other characteristics, it has been increasingly used. At the same time, in recent years, with the improvement of the foundation construction level, the Bailey truss can be disassembled and assembled as a whole or in bulk, and the construction efficiency has increased significantly. Compared with other types of supports, such as scaffolding, it has more advantages, its application value will be very good, and its application range will also be larger and larger.
[0003] During the lapping process of the existing Bailey truss, after two Bailey truss sheets are lifted by a crane, the operator laps the Bailey truss sheets. However, during the lapping process in the lifted state, it is difficult to ensure that the two Bailey truss sheets always remain parallel, which may lead to potential quality problems in the lapped Bailey truss, resulting in certain risks during the subsequent use of the Bailey truss, and even causing personal injuries. Summary of the Invention
[0004] The purpose of the present invention is to provide a correction mechanism for rapid lapping of Bailey trusses and a method for rapid lapping of Bailey trusses. By moving the second push plate, multiple groups of third connection seats on the second push plate are driven to move. The movement of multiple groups of third connection seats drives the parallel correction wheels to roll on the two-sided Bailey truss sheets, so that they are always pressed against the two-sided Bailey truss sheets during the lapping process, ensuring that the two-sided Bailey truss sheets always remain parallel during the lapping process, thereby maintaining the stability of the final lapping quality, improving the stability and precision of the lapped Bailey truss frame unit, and avoiding potential hazards during subsequent use and causing personal injuries.
[0005] To achieve the above purpose, the present invention provides the following technical solution: A correction mechanism for rapid lapping of Bailey trusses, including a base, one end of the base is fixedly provided with a pushing mechanism, and the other end of the base away from the pushing mechanism is fixedly provided with a parallel mechanism; The pushing mechanism includes a first connection seat fixedly connected to the base, telescopic rods are arranged at both ends of the first connection seat, one end of the telescopic rod penetrates through a fixing piece, one end of the fixing piece is fixedly provided with a first push plate, one end of the telescopic rod is also connected to a connecting piece, and a first sliding seat is further fixedly provided at the lower end of the first push plate; The parallel mechanism includes a second connecting seat fixedly connected to the upper end of the base. An electric push rod is fixedly arranged on the second connecting seat. The output end of the electric push rod is connected to a second push plate. Two groups of third connecting seats are arranged at both ends of the second push plate. A first spring is arranged inside the third connecting seat. One end of the first spring is connected to a sliding rod. A plurality of limiting blocks are arranged on the sliding rod. A whistle is also arranged on the sliding rod. A second spring is arranged inside the sliding rod. One end of the second spring is connected to a second sliding seat. A buffer piece is slidably arranged outside the second sliding seat. The second sliding seat penetrates through the buffer piece and is connected to a fourth connecting seat. One end of the fourth connecting seat is fixedly provided with a first fixing column. The first fixing column penetrates through and is connected to a parallel alignment wheel. A limiting seat is also fixedly arranged at the upper end of the third connecting seat. A second fixing column is arranged at the lower end of the limiting seat. A limiting plate is arranged through the lower end of the second fixing column.
[0006] Preferably, the size of the first sliding seat is adapted to the Bailey truss.
[0007] Preferably, a hole is arranged inside the third connecting seat, and the size is adapted to the sliding rod.
[0008] Preferably, the gap of the limiting block is adapted to the limiting plate.
[0009] Preferably, a groove is arranged at the upper end of the third connecting seat, and the size is adapted to the limiting plate.
[0010] Preferably, one end of the limiting block is arc-shaped and the other end is right-angled.
[0011] Preferably, both the buffer piece and the parallel alignment wheel are designed with elastic materials.
[0012] A method for quickly lapping a Bailey truss, and its usage method includes the following steps: Step 1: First measure the size of the cross beam in the Bailey truss frame unit to be lapped. Use a crane to lift the Bailey truss to the first sliding seat. Drive the telescopic rod to contract through the first connecting seat, and the first push plate drives two Bailey trusses to approach the pre-measured distance.
[0013] Step 2: After the Bailey trusses are stable at the pre-measured distance, insert the limiting plate into the third connecting seat to ensure the stability of the sliding rod and the third connecting seat without displacement.
[0014] Step 3: Drive multiple groups of parallel alignment wheels to slide through the telescopic movement of the electric push rod, so that the two Bailey trusses placed on the first sliding seat are parallel, which is convenient for installing the frame unit.
[0015] Step 4: After a single Bailey truss frame unit is installed, use a crane to lift out the installed frame unit.
[0016] Step Five: Repeat the above Steps One to Four to obtain a number of required Bailey frame units, and connect the multiple Bailey frame units end to end for lapping to obtain the required Bailey frame.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention utilizes the movement of the second push plate to drive the movement of multiple groups of third connecting seats on the second push plate. The movement of the multiple groups of third connecting seats drives the parallel correction wheels to roll on the Bailey plates on both sides, so that they are always pressed against the Bailey plates on both sides during the lapping process, enabling the Bailey plates on both sides to always maintain a parallel state during the lapping process, thereby ensuring the stability of the final lapping quality, improving the stability and precision of the lapped Bailey frame units, and avoiding potential hazards and personnel injuries during subsequent use.
[0018] 2. During the movement of the parallel correction wheels, they continuously press against the Bailey plates. At the same time, if the second sliding seat is displaced, some gas flows out of the whistle to emit a sound, thereby detecting whether the Bailey plates are deformed and whether the quality of the Bailey plates to be assembled is qualified. This avoids using deformed Bailey plates that affect the quality of the lapped Bailey frame and prevents potential safety hazards in the finally lapped Bailey frame and accidents during use.
[0019] 3. After passing the inspection, workers assemble the two groups of Bailey plates. The assembled Bailey frame unit is lifted and taken out by a crane. The telescopic rod on one side remains stationary, and the crane lifts and reinstalls the Bailey plates for assembly without the need for further measurement and telescoping. After reinstallation, the electric push rod extends to drive the parallel correction wheels to make the Bailey plates on both sides parallel and to detect whether the Bailey plates on both sides are qualified, avoiding repeated work by staff on a batch of Bailey plates and reducing the workload of the staff.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.
[0023] The present invention provides a correction mechanism for rapid lapping of a Bailey truss, including a base 1, a pushing mechanism 2 fixedly arranged at one end of the base 1, and a parallel mechanism 3 fixedly arranged at one end of the base 1 away from the pushing mechanism 2; The pushing mechanism 2 includes a first connecting seat 21 fixedly connected to the base 1. Telescopic rods 22 are arranged at both ends of the first connecting seat 21. A fixed plate 23 is penetrated through one end of each telescopic rod 22. A first pushing plate 24 is fixedly arranged at one end of the fixed plate 23. One end of each telescopic rod 22 is also connected to a connecting piece 231. A first sliding seat 241 is also fixedly arranged at the lower end of the first pushing plate 24; The parallel mechanism 3 includes a second connecting seat 31 fixedly connected to the upper end of the base 1. An electric push rod 32 is fixedly arranged on the second connecting seat 31. The output end of the electric push rod 32 is connected to a second push plate 33. Two groups of third connecting seats 34 are arranged at both ends of the second push plate 33. A first spring 341 is arranged inside the third connecting seat 34. One end of the first spring 341 is connected to a sliding rod 35. A plurality of limiting blocks 351 are arranged on the sliding rod 35. A whistle 371 is also arranged on the sliding rod 35. A second spring 373 is arranged inside the sliding rod 35. One end of the second spring 373 is connected to a second sliding seat 372. A buffer piece 37 is slidably arranged outside the second sliding seat 372. The second sliding seat 372 penetrates through the buffer piece 37 and is connected to a fourth connecting seat 36. One end of the fourth connecting seat 36 is fixedly provided with a first fixing column 361. The first fixing column 361 penetrates and is connected to a parallel alignment wheel 362. A limiting seat 38 is also fixedly arranged at the upper end of the third connecting seat 34. A second fixing column 382 is arranged at the lower end of the limiting seat 38. A limiting plate 381 is arranged through the lower end of the second fixing column 382.
[0024] When using this device, first measure the size of the cross beam in the Bailey frame unit to be lapped. Use a crane to lift two groups of Bailey sheets 11 to be lapped into the first sliding seat 241 respectively. After the two groups of Bailey sheets 11 are lifted in, the telescopic rod 22 is extended and retracted to drive the fixed piece 23 to move. The movement of the fixed piece 23 drives the first push plate 24 to move. The movement of the first push plate 24 drives the first sliding seat 241 to move, and cooperate to bring the two groups of Bailey sheets 11 on the first sliding seat 241 closer to the pre-measured distance, facilitating subsequent installation by workers.
[0025] When the two groups of Bailey sheets 11 move, the two groups of Bailey sheets 11 respectively squeeze the parallel alignment wheels 362. The parallel alignment wheels 362 are squeezed to drive the fourth connecting seat 36 to move. The movement of the fourth connecting seat 36 drives the sliding rod 35 to slide into the third connecting seat 34. The sliding rod 35 squeezes the first spring 341. The limiting block 351 on the sliding rod 35 squeezes the limiting plate 381, causing the limiting plate 381 to slide along the second fixing column 382, and at the same time being restricted by the limiting seat 38 and not detaching from the second fixing column 382. When the two groups of Bailey sheets 11 move to the pre-measured distance, insert the limiting plate 381 into the third connecting seat 34 to ensure the stability of the third connecting seat 34 and the sliding rod 35 and no longer displace. After stabilization, the electric push rod 32 drives the second push plate 33 to move. The movement of the second push plate 33 drives all the multiple groups of third connecting seats 34 on the second push plate 33 to move, driving the parallel alignment wheels 362 to roll with the Bailey sheets 11 on both sides and squeezing the Bailey sheets 11 on both sides to make the Bailey sheets 11 on both sides parallel, improving the stability of the Bailey frame unit.
[0026] Meanwhile, during the sliding process of the parallel alignment wheel 362, if the Bailey sheets 11 on both sides are deformed, the parallel alignment wheel 362 is squeezed by the second spring 373. The second spring 373 squeezes the second sliding seat 372, driving the second sliding seat 372 to move, driving the fourth connecting seat 36 to move, and driving the parallel alignment wheel 362 to move, so that the parallel alignment wheel 362 continuously squeezes the Bailey sheet 11. At the same time, due to the displacement of the second sliding seat 372, part of the gas flows out of the whistle 371 to make a sound, thereby testing whether the Bailey sheet 11 is deformed and whether the quality of the Bailey sheet 11 to be assembled is qualified.
[0027] After passing the inspection, the worker assembles the two groups of Bailey sheets 11. The assembled Bailey frame unit is lifted out by a crane. The telescopic rod 22 on one side keeps its position unchanged and is lifted into the Bailey sheet 11 by the crane for assembly again. There is no need for measurement and telescoping. After being lifted in, the electric push rod 32 extends to drive the parallel alignment wheel 362 to make the Bailey sheets 11 on both sides parallel and detect whether the Bailey sheets 11 on both sides are qualified.
[0028] In an optional embodiment, the size of the first sliding seat 241 is adapted to the Bailey sheet 11.
[0029] It should be noted that after the Bailey sheet 11 is lifted in, ensure that the first sliding seat 241 wraps the Bailey sheet 11 to prevent the Bailey sheet 11 from tipping over during pushing, which may cause injury to construction workers.
[0030] In an optional embodiment, a hole is provided inside the third connecting seat 34, and its size is adapted to the sliding rod 35.
[0031] It should be noted that when the telescopic rod 22 expands and contracts, it drives the first push plate 24 to move and squeeze the sliding rod 35, so that the sliding rod 35 slides into the third connecting seat 34. Ensure that the length after extrusion is consistent with the pre-measured length to ensure the normal use of the device.
[0032] In an optional embodiment, the gap of the limiting block 351 is adapted to the limiting plate 381.
[0033] It should be noted that after the sliding rod 35 is stably inserted into the third connecting seat 34, the worker manually inserts the limiting plate 381 into the gap of the limiting block 351 on the sliding rod 35 inside the third connecting seat 34 to ensure the stability of the third connecting seat 34 and the sliding rod 35, which is convenient for subsequent use. At the same time, after the splicing is completed, the limiting plate 381 is manually pulled out, and the device can splice Bailey frame units of different sizes.
[0034] In an optional embodiment, a groove is provided at the upper end of the third connecting seat 34, and its size is adapted to the limiting plate 381.
[0035] It should be noted that the limiting plate 381 slides along the second fixing post 382 in the groove of the third connecting seat 34 and is restricted inside the limiting seat 38 by the second fixing post 382 to prevent the limiting plate 381 from detaching during use.
[0036] In an alternative embodiment, one end of the limiting block 351 is arc-shaped and the other end is right-angled.
[0037] It should be noted that when the second fixing post 382 is inserted, the sliding rod 35 can only enter the inside of the third connecting seat 34 and cannot automatically detach from the inside of the third connecting seat 34.
[0038] In an alternative embodiment, both the buffer piece 37 and the parallel alignment wheel 362 are designed with elastic materials.
[0039] It should be noted that the buffer piece 37 ensures that the vibration of the fourth connecting seat 36 and the sliding rod 35 will not damage the device and extends the service life of the device. The parallel alignment wheel 362 rolling with the two side Bailey sheets 11 will not damage the Bailey sheets 11 and avoids unnecessary damage to the Bailey sheets 11 when the pressure is too high.
[0040] A calibration mechanism for rapid latching of a Bailey truss, and its usage method includes the following steps: Step 1: First measure the size of the cross beam in the Bailey truss frame unit to be latched. Use a crane to lift the Bailey sheet 11 to be latched onto the first sliding seat 241. Drive the telescopic rod 22 to contract through the first connecting seat 21, and the first push plate 24 drives the two Bailey sheets 11 closer to the pre-measured distance.
[0041] Step 2: After the Bailey sheet 11 is stabilized at the pre-measured distance, insert the limiting plate 381 into the inside of the third connecting seat 34 to ensure the stability of the sliding rod 35 and the third connecting seat 34 without displacement.
[0042] Step 3: Drive multiple groups of parallel alignment wheels 362 to slide by the telescopic movement of the electric push rod 32, so that the two groups of Bailey sheets 11 placed on the first sliding seat 241 are parallel, which is convenient for installing the frame unit.
[0043] Step 4: After a single Bailey truss frame unit is installed, use a crane to lift out the installed frame unit.
[0044] Step 5: Repeat the above steps 1 to 4 to obtain several required Bailey truss frame units, and connect the multiple Bailey truss frame units end to end to obtain the required Bailey truss.
[0045] Working principle: When using this device, first measure the size of the cross beam in the Bailey frame unit to be lapped. Use a crane to lift two groups of Bailey sheets 11 to be lapped onto the first sliding seat 241 respectively. After the two groups of Bailey sheets 11 are lifted in, the telescopic rod 22 is extended or retracted to drive the fixed piece 23 to move. The movement of the fixed piece 23 drives the first push plate 24 to move, and the movement of the first push plate 24 drives the first sliding seat 241 to move, so as to move the two groups of Bailey sheets 11 on the first sliding seat 241 closer to the pre-measured distance, which is convenient for subsequent workers to install.
[0046] When the two groups of Bailey sheets 11 move, the two groups of Bailey sheets 11 respectively squeeze the parallel alignment wheels 362. The parallel alignment wheels 362 are squeezed to drive the fourth connecting seat 36 to move. The movement of the fourth connecting seat 36 drives the sliding rod 35 to slide into the third connecting seat 34. The sliding rod 35 squeezes the first spring 341, and the limiting block 351 on the sliding rod 35 squeezes the limiting plate 381, so that the limiting plate 381 slides along the second fixed column 382 and is restricted by the limiting seat 38 at the same time and will not break away from the second fixed column 382. When the two groups of Bailey sheets 11 move to the pre-measured distance, insert the limiting plate 381 into the third connecting seat 34 to ensure the stability of the third connecting seat 34 and the sliding rod 35 and prevent further displacement. After stabilization, the electric push rod 32 drives the second push plate 33 to move. The movement of the second push plate 33 drives all the multiple groups of third connecting seats 34 on the second push plate 33 to move, driving the parallel alignment wheels 362 to roll with the Bailey sheets 11 on both sides and squeezing the Bailey sheets 11 on both sides to make the Bailey sheets 11 on both sides parallel, thus improving the stability of the Bailey frame unit.
[0047] At the same time, during the sliding process of the parallel alignment wheels 362, if the Bailey sheets 11 on both sides are deformed, the parallel alignment wheels 362 are squeezed by the second spring 373. The second spring 373 squeezes the second sliding seat 372, driving the second sliding seat 372 to move, driving the fourth connecting seat 36 to move, and driving the parallel alignment wheels 362 to move, so that the parallel alignment wheels 362 continuously squeeze the Bailey sheets 11. At the same time, due to the displacement of the second sliding seat 372, part of the gas flows out of the whistle 371 to make a sound, so as to detect whether the Bailey sheets 11 are deformed and check whether the quality of the Bailey sheets 11 to be assembled is qualified.
[0048] After passing the inspection, the worker assembles the two groups of Bailey sheets 11. The assembled Bailey frame unit is lifted and taken out by a crane. One side of the telescopic rod 22 remains stationary, and the crane is used to lift the Bailey sheets 11 again for assembly without the need for further measurement and telescoping. After lifting in, the electric push rod 32 extends to drive the parallel alignment wheels 362 to make the Bailey sheets 11 on both sides parallel and detect whether the Bailey sheets 11 on both sides are qualified.
[0049] After lifting the Bailey truss 11, ensure that the first sliding seat 241 wraps the Bailey truss 11 to prevent the Bailey truss 11 from tipping over during pushing, which may cause injury to construction workers. When the telescopic rod 22 expands and contracts, it drives the first push plate 24 to move and squeeze the sliding rod 35, causing the sliding rod 35 to slide into the third connecting seat 34. Ensure that the length after extrusion is consistent with the pre-measured length to ensure the normal use of the device. After the sliding rod 35 is stably inserted into the third connecting seat 34, the worker manually inserts the limiting plate 381 into the gap of the limiting block 351 on the sliding rod 35 inside the third connecting seat 34 to ensure the stability between the third connecting seat 34 and the sliding rod 35, facilitating subsequent use. At the same time, after the splicing is completed, manually pull out the limiting plate 381. The device can be spliced with Bailey truss frame units of different sizes. The limiting plate 381 slides along the second fixing column 382 in the groove of the third connecting seat 34 and is restricted inside the limiting seat 38 by the second fixing column 382 to prevent the limiting plate 381 from detaching during use. When the second fixing column 382 is inserted, the sliding rod 35 can only enter the inside of the third connecting seat 34 and cannot automatically detach from the inside of the third connecting seat 34.
