Description

Technical Field

[0001] The present invention relates to the technical field of steel temporary bridge hoisting, and particularly to a hoisting structure for steel temporary bridge construction. Background Art

[0002] In actual steel temporary bridge construction hoisting work, the steel temporary bridge is mainly assembled by Bailey frames, and the bridge deck is laid above the Bailey frames. In the hoisting work of a long steel temporary bridge, it is necessary to ensure the stable hoisting of the Bailey frames to ensure the safety of steel temporary bridge construction. The Bailey frame is a modular prefabricated steel bridge system, which is composed of standardized Bailey sheets connected by pin shafts and has the characteristics of rapid assembly and flexible combination. At present, when the hoisting structure for steel temporary bridge construction hoists a long Bailey frame, the middle part of the Bailey frame is prone to collapse, which is not convenient for automatic correction work, and it is easy to cause subsequent difficulty in disassembling the pin shafts of the Bailey frame, and even cause permanent deformation of the Bailey frame. At the same time, it is not convenient to automatically maintain a prestressed micro-arch during the installation of the Bailey frame, which affects the installation quality. During the hoisting process, because it is a broken bridge, usually only one crane can be used for hoisting, and the hoisting stability is poor, and it is not convenient to use pile cylinders for vertical traction.

There are two hoisting U-shaped frames 101, and the detachable beam 102 is fixedly installed at the bottom of the two hoisting U-shaped frames 101 through bolts; the hoisting U-shaped frame 101 is used to connect the Bailey truss; the detachable beam 102 is located in the middle of the Bailey truss.

[0022] Among them, the hoisting connecting member 1 further includes: a compensation hydraulic cylinder 103, a support rod 104, a support auxiliary rod 105, a steel wire bolt 106, and a steel wire 1061. Two compensation hydraulic cylinders 103 are fixedly installed on the detachable beam 102; the output shafts of the two compensation hydraulic cylinders 103 are fixedly installed with support rods 104, and support auxiliary rods 105 are rotatably installed at both ends of the support rod 104, and the other ends of the two support auxiliary rods 105 are respectively placed on the detachable beam 102; steel wire bolts 106 are respectively threadedly connected to the two hoisting U-shaped frames 101, and the four steel wire bolts 106 are grouped in pairs, and a steel wire 1061 is connected between each group of steel wire bolts 106; the two steel wires 1061 are used to connect to the crane hook; the support rod 104 and the support auxiliary rod 105 are used to support the Bailey truss; the linear detection member 2 includes: a linear connecting plate 201, a linear tension spring 202, and a power-on steel wire 203. Linear connecting plates 201 are respectively fixedly installed on the two hoisting U-shaped frames 101 by bolts; linear tension springs 202 are respectively fixedly installed on the two linear connecting plates 201; a power-on steel wire 203 is fixedly installed between the two linear tension springs 202; the power-on steel wire 203 is made of a conductive material; the detection control member 3 includes: a detection mounting frame 301, a mounting magnet 302, a depression detection shaft 303, and a power-on column 3031. A slot is provided on the detection mounting frame 301; the detection mounting frame 301 is used to be inserted into the main beam of the Bailey truss; a mounting magnet 302 is fixedly embedded on the detection mounting frame 301, and the mounting magnet 302 is used to magnetically attract the main beam of the Bailey truss; a depression detection shaft 303 is slidably installed on the detection mounting frame 301, and a groove is provided on the depression detection shaft 303; an insulating coating is provided on the outer side of the depression detection shaft 303; a power-on column 3031 is installed in the groove on the depression detection shaft 303; the power-on steel wire 203 is located in the groove on the depression detection shaft 303; there is a gap between the power-on steel wire 203 and the power-on column 3031; the power-on steel wire 203 is electrically connected to the control valves of the two compensation hydraulic cylinders 103. By using the detection control member 3, when hoisting the Bailey truss, the deformation depression condition in the middle of the Bailey truss after hoisting can be automatically detected. Especially for a relatively long steel Bailey truss bridge, when the Bailey truss deforms, it can be automatically controlled for compensation, which can improve the straightness of this structure during hoisting, reduce the deformation caused by its own weight, and can achieve correction. At the same time, the detection of this structure is direct and fast. By using the detection control member 3 in cooperation with the linear detection member 2, it is more suitable for the hoisting work of large-span bridge construction. To ensure that in the actual hoisting work, if the Bailey truss continuously maintains a depressed deformation, the bending of the Bailey truss will damage the overall stability of its truss structure, resulting in local stress concentration and reducing the bending and shear resistance capabilities;If the deformation exceeds the yield limit of the material, it may cause cracks or weld disconnection, and in severe cases, lead to the fracture or collapse of the main beam, threatening the hoisting safety. It can avoid the problem that the bent Bailey truss squeezes the Bailey pin, making it difficult to disassemble the subsequent Bailey pin. If the Bailey truss is bent and sunken, the Bailey truss will drive the detection and installation frame 301 to press down at this time, driving the sunken detection shaft 303 and the power connection column 3031 to descend. However, the linear spring 202 can pull the power connection wire 203 to maintain the straightness of the power connection wire 203. At this time, when the power connection column 3031 descends and fits the power connection wire 203 due to the deformation of the Bailey truss, the compensation hydraulic cylinder 103 can drive the support rod 104 to move upward, driving the support sub-rod 105 to support the Bailey truss together and perform deformation compensation extrusion on the Bailey truss.

[0023] Among them, the detection and control component 3 further includes: a compensation electromagnet 304 and a compensation spring 305. The compensation electromagnet 304 is fixedly installed inside the detection and installation frame 301; the compensation electromagnet 304 magnetically attracts the sunken detection shaft 303; the compensation spring 305 is sleeved inside the detection and installation frame 301; the compensation spring 305 is connected between the compensation electromagnet 304 and the power connection column 3031; the in-place detection component 4 includes: an in-place detection strip 401 and a V-shaped elastic piece 402. The in-place detection strip 401 is slidably installed on the hoisting U-shaped frame 101; two V-shaped elastic pieces 402 are fixedly installed at the bottom of the in-place detection strip 401, and the end parts of the two V-shaped elastic pieces 402 are respectively connected to the hoisting U-shaped frame 101; the in-place detection strip 401 is used to fit the Bailey truss; the in-place detection component 4 further includes: an in-place switch 403. The in-place switch 403 is fixedly installed at the bottom of the in-place detection strip 401, and the bottom of the in-place switch 403 fits the inner side of the hoisting U-shaped frame 101; the in-place switch 403 is electrically connected to the compensation electromagnet 304; the in-place switch 403 is located inside the hoisting U-shaped frame 101. By using the in-place detection component 4, when this structure is hoisted and placed on the pile barrel, it can be automatically corrected, which can avoid the operator forgetting to operate. By controlling the middle part of the Bailey truss to bend upward, the prestress can be adjusted. After the Bailey truss is fixed on the pile barrel subsequently, under the action of its own weight, the originally upward bending bulge in the middle will tend to be horizontal. By using the automatic detection method when placing the Bailey truss, it can avoid excessive deformation of the Bailey truss caused by prestress bending the Bailey truss in advance. This structure can improve the levelness of the Bailey truss after installation and reduce the hidden danger of deformation of the Bailey truss under its own weight after installation. When the Bailey truss is hoisted to the pile barrel, the top of the in-place detection strip 401 is no longer squeezed by the Bailey truss, and the in-place switch 403 can control the compensation electromagnet 304 to cut off the power. At this time, the compensation spring 305 can squeeze the sunken detection shaft 303, driving the power connection column 3031 to move downward and fit the power connection wire 203. At this time, the compensation hydraulic cylinder 103 can further drive the support rod 104 to move upward to jack up the middle part of the Bailey truss and apply prestress.

[0024] Embodiment 2, on the basis of Embodiment 1, the hoisting guide member 5 includes: a guide ring 501 and a towing rope 502. Three guide rings 501 are fixedly installed on the detachable beam 102, and the towing rope 502 slides through the three guide rings 501; the end of the towing rope 502 is an annular structure; the through holes between the three guide rings 501 are in a straight line; the towing rope 502 passes through the Bailey truss; the hoisting guide member 5 further includes: a limiting ball 503, the limiting ball 503 is fixedly installed on the towing rope 502, and the limiting ball 503 is located outside the three guide rings 501; the pile barrel counterweight member 6 includes: pile barrel tiles 601, drag reduction beads 602, proximity electromagnets 603 and counterweight blocks 604, the pile barrel tiles 601 are arc-shaped structures; the bottom of the towing rope 502 is threadedly connected to the pile barrel tiles 601 by a stud; three rows of drag reduction beads 602 are embedded on the pile barrel tiles 601; the three rows of drag reduction beads 602 are used to fit on the outside of the pile barrel; two proximity electromagnets 603 are fixedly installed on the pile barrel tiles 601, and the two proximity electromagnets 603 are used to magnetically attract the pile barrel; a counterweight block 604 is fixedly installed at the bottom of the pile barrel tiles 601; the towing rope 502 is used to tow the hoisting U-shaped frame 101. Using the pile barrel counterweight member 6 can facilitate the staff to align the Bailey truss with the pile barrel by using the pile barrel. At the same time, this structure can facilitate the staff to conduct guidance externally, which can improve the flexibility of the use of this structure. Especially for the use of broken bridges, the bridge is usually constructed step by step from one end, and usually only one crane can be used for hoisting. It is difficult for one crane to control the falling position of the Bailey truss. This structure can guide downward from the pile barrel at one end, and the installation position of the Bailey truss can be controlled by manual traction at the other end. When lowering the Bailey truss, first magnetically attract the pile barrel with the proximity electromagnet 603. At this time, cooperate with the drag reduction beads 602 to reduce resistance and the counterweight block 604 for counterweight. At this time, the towing rope 502 will be towed, driving the detachable beam 102, that is, the end of the Bailey truss to align with the pile barrel, assisting the staff to adjust the landing point and being safer.

[0025] Working principle of this embodiment: First, after inserting the hoisting U-shaped frame 101 into the Bailey truss, the detachable beam 102 is installed below the two hoisting U-shaped frames 101 through bolts. The steel wire rope 1061 is connected to the crane hook. Under the control of the crane, the Bailey truss is lifted. At this time, if the Bailey truss is bent and sunken, the Bailey truss will drive the detection and installation frame 301 to press down, driving the sunken detection shaft 303 and the power connection column 3031 to descend. However, the linear tension spring 202 can pull the power connection wire 203 to maintain the straightness of the power connection wire 203. At this time, when the power connection column 3031 descends and fits the power connection wire 203 due to the deformation of the Bailey truss, the compensation hydraulic cylinder 103 can drive the support rod 104 to move upward, driving the support auxiliary rod 105 to support the Bailey truss together, performing deformation compensation extrusion on the Bailey truss. When the Bailey truss is supported, it drives the detection and installation frame 301 to move upward, and the power connection column 3031 and the power connection wire 203 are just separated, which can realize automatic deformation correction and automatically stop after correction. When the Bailey truss is hoisted to the pile barrel, because the crane continuously lowers the cable, at this time, the hoisting U-shaped frame 101 is no longer pressed by the Bailey truss, and the top of the in-place detection strip 401 is no longer squeezed by the Bailey truss. At this time, under the extrusion of the V-shaped elastic piece 402, the in-place switch 403 can control the power-off of the compensation electromagnet 304. At this time, the compensation spring 305 can squeeze the sunken detection shaft 303, driving the power connection column 3031 to move downward and compensating a certain distance to fit the power connection wire 203. At this time, the compensation hydraulic cylinder 103 can further drive the support rod 104 to move upward to jack up the middle of the Bailey truss to apply prestress; when lowering the Bailey truss, first magnetize the pile barrel with the proximity electromagnet 603. At this time, cooperate with the drag reduction beads 602 to reduce resistance and the counterweight 604 for counterweight. At this time, the towing rope 502 will be towed, driving the detachable beam 102, that is, the end of the Bailey truss to align with the pile barrel. At the same time, the other end of the towing rope 502 close to the limit ball 503 can be manually controlled to tow to adjust the falling position of the other end of the Bailey truss, with flexible and quick adjustment.
