[0002] In the actual construction and hoisting work of steel temporary bridges, the steel temporary bridges are mainly assembled by Bailey frames, and then the bridge deck is laid on top of the Bailey frames. In the construction and hoisting work of longer steel temporary bridges, it is necessary to ensure that the Bailey frames are stably hoisted to ensure the safety of the steel temporary bridge construction. The Bailey frame is a modular assembled steel bridge system, which is composed of standardized Bailey plates connected by pins. It has the characteristics of fast assembly and flexible combination.

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] The present invention adopts a detection control component to automatically detect the deformation and depression of the middle part of the Bailey frame after lifting when the Bailey frame is lifted. Especially for the Bailey frame of a longer steel temporary bridge, it can automatically control compensation when the Bailey frame is deformed, thereby improving the straightness of the structure during lifting, reducing the deformation caused by its own weight, and realizing correction. It is more suitable for large-span bridge construction and lifting work, avoiding the bending of the Bailey frame to destroy the overall stability of its truss structure, causing local stress concentration, reducing the bending and shearing resistance, and ensuring that its Bailey pin can be easily disassembled.
[0017] The use of in-place detection parts can automatically correct the structure when it is hoisted and placed in the pile barrel, which can prevent workers from forgetting to operate. Prestress adjustment can be achieved by controlling the upward bending of the middle part of the Bailey frame. After the Bailey frame is subsequently fixed to the pile barrel, under the action of its own weight, the original upward curved bulge in the middle will approach the horizontal level. By utilizing the automatic detection method when placing the Bailey frame, the pre-prestressed bending of the Bailey frame in advance can be avoided, which may cause excessive deformation of the Bailey frame. This structure can improve the horizontality of the Bailey frame after installation and reduce the hidden danger of deformation of the Bailey frame under its own weight after installation.
[0018] The use of pile counterweights can make it easier for workers to use the pile to guide the Bailey frame to align with the pile. At the same time, this structure can facilitate external guidance by workers, which can improve the flexibility of the structure. Especially for broken bridges, usually only one crane can be used for lifting, and one crane is difficult to control the falling position of the Bailey frame. This structure can guide downward from the pile at one end, and the other end can be manually pulled to control the installation position of the Bailey frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Among them, the lifting connection part 1 also includes: a compensating hydraulic cylinder 103, a support rod 104, a support sub-rod 105, a steel rope bolt 106 and a steel rope 1061. Two compensating hydraulic cylinders 103 are fixedly installed on the detachable beam 102; the output shafts of the two compensating hydraulic cylinders 103 are fixedly installed with a support rod 104, and the two ends of the support rod 104 are rotatably installed with a support sub-rod 105, and the other ends of the two support sub-rods 105 are respectively placed on the detachable beam 102; the two lifting U-shaped frames 101 are respectively threadedly connected with a steel rope bolt 106, and the four steel rope bolts 106 are grouped in pairs, and each group of steel rope bolts 106 are connected by a steel rope 1061; the two steel rope bolts 106 are connected in pairs. The rope 1061 is used to connect the crane hook; the support rod 104 and the support sub-rod 105 are used to support the Bailey frame; the linear detection part 2 includes: a linear connecting plate 201, a linear tension spring 202 and an electrical wire 203, and the two lifting U-shaped frames 101 are respectively fixedly installed with a linear connecting plate 201 by bolts; the two linear connecting plates 201 are respectively fixedly installed with a linear tension spring 202; the electrical wire 203 is fixedly installed between the two linear tension springs 202; the electrical wire 203 is made of conductive material; the detection control part 3 includes: a detection mounting frame 301, a mounting magnet 302, a recessed detection shaft 303 and an electrical post 3031, and a slot is provided on the detection mounting frame 301 ; The detection mounting frame 301 is used to be plugged into the main beam of the Bailey frame; 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 frame; a recessed detection shaft 303 is slidably mounted on the detection mounting frame 301, and a groove is provided on the recessed detection shaft 303; an insulating coating is provided on the outer side of the recessed detection shaft 303; a power connection post 3031 is installed in the groove on the recessed detection shaft 303; the power connection wire 203 is located in the groove on the recessed detection shaft 303; a gap is provided between the power connection wire 203 and the power connection post 3031; the power connection wire 203 and the power connection post 3031 are electrically connected to the control of the two compensation hydraulic cylinders 103 The valve is controlled by the detection control component 3, which can automatically detect the deformation and depression of the middle part of the Bailey frame after lifting when the Bailey frame is hoisted. Especially for the Bailey frame of a longer steel temporary bridge, the Bailey frame can be automatically controlled and compensated when it is deformed, which can improve the straightness of the structure during hoisting, reduce the deformation caused by its own weight, and realize correction. At the same time, the detection of the structure is direct and fast, and the detection control component 3 can be used in conjunction with the straight line detection component 2, which is more suitable for the construction and hoisting of large-span bridges, ensuring that in the actual hoisting work, if the Bailey frame continues to maintain a concave deformation, the bending of the Bailey frame will destroy the overall stability of its truss structure, resulting in local stress concentration and reduced bending and shearing capacity;If the deformation exceeds the yield limit of the material, it may cause cracks or weld separation, and in severe cases, lead to the fracture or collapse of the main beam, threatening the safety of the lifting. This can avoid the bending of the Bailey frame and the squeezing of the Bailey pin, which makes it difficult to remove the Bailey pin later. If the Bailey frame bends and becomes concave, the Bailey frame will drive the detection mounting frame 301 to press down, driving the concave 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 deformation of the Bailey frame drives the power connection column 3031 to descend and fit the power connection wire 203, the compensation hydraulic cylinder 103 can drive the support rod 104 to move upward, driving the supporting auxiliary rod 105 to support the Bailey frame together, and compensating and squeezing the Bailey frame for deformation.
[0035] Among them, the detection control part 3 also includes: a compensation electromagnet 304 and a compensation spring 305, the detection mounting frame 301 is fixedly installed with a compensation electromagnet 304; the compensation electromagnet 304 magnetically attracts the recessed detection shaft 303; the detection mounting frame 301 is internally sleeved with a compensation spring 305; the compensation spring 305 is connected between the compensation electromagnet 304 and the power post 3031; the in-place detection part 4 includes: an in-place detection bar 401 and a V-shaped spring 402, the in-place detection bar 401 is slidably mounted on the hoisting U-shaped The in-place detection strip 401 is fixedly mounted with two V-shaped spring clips 402 at the bottom, and the ends of the two V-shaped spring clips 402 are respectively connected to the hoisting U-shaped frame 101; the in-place detection strip 401 is used to fit the Bailey frame; the in-place detection member 4 also includes: an in-place switch 403, a in-place switch 403 is fixedly mounted at the bottom of the in-place detection strip 401, and the bottom of the in-place switch 403 is fitted to 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 in On the inner side of the hoisting U-shaped frame 101, the in-place detection member 4 can automatically correct when the structure is hoisted and placed on the pile barrel, which can avoid the staff forgetting to operate. By controlling the upward bending of the middle part of the Bailey frame, the prestressing force can be adjusted. After the Bailey frame is fixed on the pile barrel, under the action of its own weight, the original upward bending bulge in the middle will approach the horizontal level. By using the automatic detection method when placing the Bailey frame, the Bailey frame can be prevented from being excessively deformed due to premature prestressed bending of the Bailey frame. This structure can improve the installation of the Bailey frame. The levelness after installation reduces the hidden danger of deformation of the Bailey frame under its own weight after installation. When the Bailey frame is hoisted to the pile barrel, the top of the in-place detection strip 401 is no longer squeezed by the Bailey frame. 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 concave detection shaft 303, and drive the power column 3031 to move down and fit the power wire 203. At this time, the compensation hydraulic cylinder 103 can further drive the support rod 104 to move upward, lift the middle part of the Bailey frame, and realize the application of prestress.
[0036] Example 2, based on Example 1, the lifting guide 5 includes: a guide ring 501 and a traction rope 502, three guide rings 501 are fixedly installed on the detachable beam 102, and the traction rope 502 slides through the three guide rings 501; the end of the traction rope 502 is a ring structure; the through hole between the three guide rings 501 is a straight line; the traction rope 502 passes through the Bailey frame; the lifting guide 5 also includes: a limit ball 503, a limit ball 503 is fixedly installed on the traction rope 502 , and the limiting ball 503 is located outside the three guide rings 501; the pile counterweight 6 includes: a pile tile 601, a drag reduction bead 602, an electromagnet 603 and a counterweight 604, the pile tile 601 is an arc structure; the bottom of the traction rope 502 is connected to the pile tile 601 through a stud thread; three rows of drag reduction beads 602 are embedded on the pile tile 601; the three rows of drag reduction beads 602 are used to fit the outside of the pile; two electromagnets 603 are fixedly installed on the pile tile 601. Iron 603, and two close to the electromagnet 603 are used to magnetically attract the pile barrel; a counterweight block 604 is fixedly installed at the bottom of the pile barrel tile 601; the traction rope 502 is used to pull and lift the U-shaped frame 101. The use of the pile barrel counterweight 6 can facilitate the staff to use the pile barrel to guide the Bailey frame to align with the pile barrel. At the same time, this structure can facilitate the staff to guide it from the outside, which can improve the flexibility of use of this structure, especially for broken bridges. Bridges are usually constructed step by step from one end, and usually only one crane can be used for lifting. It is difficult for one crane to control the falling position of the Bailey frame. This structure can guide downward from the pile barrel at one end, and the other end is manually pulled to control the installation position of the Bailey frame. When lowering the Bailey frame, first magnetically attract the pile barrel close to the electromagnet 603. At this time, the drag reduction beads 602 are used to reduce drag, and the counterweight block 604 is used for counterweight. At this time, the traction rope 502 will be pulled, driving the detachable beam 102, that is, the end of the Bailey frame is aligned with the pile barrel, assisting the staff to adjust the landing point, which is safer.
[0037] The working principle of this embodiment is as follows: First, after the lifting U-shaped frame 101 is inserted into the Bailey frame, the detachable beam 102 is installed under the two lifting U-shaped frames 101 by bolts, and the steel rope 1061 is connected to the crane hook. Under the control of the crane, the Bailey frame is lifted. At this time, if the Bailey frame bends and sags, the Bailey frame will drive the detection mounting frame 301 to press down, driving the sag detection shaft 303 and the power connection column 3031 to descend, but the linear tension spring 202 can pull the power connection wire 203 to keep the power connection wire The straightness of the wire 203 is improved. At this time, when the Bailey frame is deformed and drives the power post 3031 to descend and fit the power wire 203, the compensation hydraulic cylinder 103 can drive the support rod 104 to move up, drive the supporting auxiliary rod 105 to support the Bailey frame together, and perform deformation compensation and extrusion on the Bailey frame. When the Bailey frame is supported, it drives the detection mounting frame 301 to move up, drives the power post 3031 and the power wire 203 to separate, and can realize automatic deformation correction. It stops automatically after correction. When hoisting to the pile barrel, because the crane continues to lower the cable, the hoisting U-shaped frame 101 is no longer pressed down by the Bailey frame, and the top of the in-place detection strip 401 is no longer squeezed by the Bailey frame. At this time, the V-shaped spring 402 is squeezed, and the in-place switch 403 can control the compensation electromagnet 304 to be de-energized. At this time, the compensation spring 305 can squeeze the concave detection shaft 303, which can drive the power column 3031 to move downward, compensate for a distance, and fit the power wire 203. At this time, the compensation hydraulic cylinder 103 can be further The driving support rod 104 moves upward to lift the middle part of the Bailey frame to achieve prestressing. When lowering the Bailey frame, the pile barrel is first magnetically attracted to the electromagnet 603. At this time, the drag reduction beads 602 are used to reduce the drag, and the counterweight block 604 is used for counterweighting. At this time, the traction rope 502 will be pulled to drive the detachable beam 102, that is, the end of the Bailey frame is aligned with the pile barrel. At the same time, the other end of the traction rope 502 close to the limit ball 503 can be manually controlled to traction to adjust the falling position of the other end of the Bailey frame, and the adjustment is flexible and fast.
