Description

Technical Field

[0001] This utility model relates to the field of steel bridge hoisting technology, specifically to a steel bridge flange hoisting system. Background Technology

[0002] Steel bridges are widely used in bridge construction. When installing steel bridges, it is generally necessary to first fabricate steel bridge segments and then use equipment such as cranes for hoisting. However, when the steel bridge is long in the transverse direction, has a large mass, and has a small working space, it is necessary to divide the steel bridge into the main body and the steel bridge flanges for hoisting operations. However, dividing the steel bridge into the main body and the steel bridge flanges makes transportation more convenient.

[0003] During bridge construction, steel trestle bridges need to be erected to meet traffic and transportation needs. If steel bridge flange hoisting operations are to be carried out, the erection of a typical steel trestle bridge needs to cover the entire overhead projection of the steel bridge to meet the requirements of the steel bridge flange hoisting operation. Moreover, it is not easy to carry out construction work in places where it is inconvenient to erect steel trestle bridges, which increases the construction difficulty and material input.

[0004] Therefore, in order to address the above problems, a steel bridge flange hoisting system is proposed. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a steel bridge flange hoisting system. This system enables the overall installation of steel bridges to be completed by erecting a steel trestle under one flange, thereby reducing the area required for the trestle, construction difficulty, and material input.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] A steel bridge flange hoisting system includes a steel trestle and a hoisting device. The steel trestle is located below the flange on one side of the main body of the steel bridge, and the length direction of the steel trestle is parallel to the length direction of the steel bridge. The hoisting device includes a hoisting moving frame, which is slidably mounted on the main body of the steel bridge along its length direction. A translation component is slidably mounted on the hoisting moving frame, and the movement direction of the translation component is horizontal and perpendicular to the length direction of the steel bridge. A lifting component is mounted on the translation component, and the lifting component is used to connect to the steel bridge flange and drive the steel bridge flange to rise and fall.

[0008] Preferably, steel rails are installed on both sides of the upper end of the main body of the steel bridge along the length of the main body, and a hoisting and moving frame is movably connected on the steel rails.

[0009] Preferably, several anchoring lugs are provided on both sides of each rail. The anchoring lugs on the same side of the rail are arranged parallel to the length of the rail. Anchoring holes are provided on the anchoring lugs, and the anchoring holes are connected to the hoisting and moving frame through anchoring components.

[0010] Preferably, the hoisting mobile frame includes a truss, with legs installed at the front and rear ends on both sides of the bottom of the truss. The bottom of the legs is movably connected to the rails via a movable component.

An upper inclined support is installed between the legs and the truss, and a lower inclined support is installed between the legs and the longitudinal bars. The truss as a whole adopts a steel structure frame, and a slide rail is installed at the bottom of the truss. The length direction of the slide rail is perpendicular to the length direction of the rails, and a translation component is movably connected to the slide rail.

[0011] Preferably, the moving component includes a wheel box located at the bottom of the outriggers. A moving power component is mounted on the wheel box, and the output end of the moving power component is connected to a steel wheel. The steel wheel is rotatably mounted on the wheel box and is in rolling connection with the rail, so as to drive the hoisting moving frame to move along the length of the rail.

[0012] Preferably, the translational component includes traveling wheels, which are movably mounted on a slide rail. A hoisting trolley is installed at the bottom of the traveling wheels, and a lifting component is installed at the bottom of the hoisting trolley.

[0031] like Figures 1-9 As shown, this utility model provides a technical solution:

[0032] A steel bridge flange 1 hoisting system includes a steel trestle 15 and a hoisting device.

The steel wheel 14 is rotatably disposed on the wheel box 11 and is tactilely connected to the rail 12 so as to drive the hoisting moving frame to move along the length direction of the rail 12.

[0037] In an optional embodiment, the translational component includes a traveling wheel 6, which is movably mounted on a slide rail 19. A hoisting trolley 7 is mounted at the bottom of the traveling wheel 6, and a lifting component is mounted at the bottom of the hoisting trolley 7. The traveling wheel 6 includes at least two sets, which are evenly distributed on the upper side of the hoisting trolley 7 to improve the stability of the hoisting and further enhance safety.

[0038] In an optional embodiment, the lifting assembly includes an electric hoist 5, with a hanger 8 provided at the lifting end of the electric hoist 5 for connecting the steel bridge flange 1; the electric hoist 5 includes at least two sets, evenly arranged on the lower side of the hoisting trolley 7, with a hanger 8 provided at the lifting end of each set of electric hoists 5; preferably, the electric hoist 5 is slidably mounted on the hoisting trolley 7, and the sliding direction is parallel to the length direction of the rail 12, so as to fine-tune the front and rear positions of the steel bridge flange 1, thereby improving the accuracy and efficiency of installation.

[0039] In an optional embodiment, the anchoring assembly includes anchor plates 20, which are disposed on both sides of the bottom of the outrigger 4. Preferably, two anchor plates 20 are disposed on each outrigger 4. The anchor plates 20 are respectively located above the anchoring lugs 10 on both sides of the rail 12. Anchors 20 are connected to anchor members by anchor rods 9. The anchor members have through holes corresponding to the anchoring holes. The anchoring holes and through holes are connected by pins 21 to achieve temporary positioning of the hoisting mobile frame on the rail 12. Preferably, the anchor rods 9 are double-ended bolts. The height of the anchor members can be adjusted by adjusting the position of the nuts so that the anchoring holes and through holes are aligned, thereby improving the practicality of the device.

[0040] Working principle: The working process is divided into flange hoisting with a steel trestle 15 below the flange and flange hoisting without a steel trestle 15 below the flange. Before hoisting, the moving power component 13 drives the steel wheel 14 to roll on the steel rail 12, thereby driving the entire hoisting device to move to the flange hoisting position. The anchoring component is connected to the anchoring lug 10 welded to the main body of the steel bridge 2 through the pin 21, completing the anchoring of the device, i.e., temporary positioning, to prevent the device from overturning during hoisting. Problem: When the flange of the steel trestle 15 is located below the hoisting position, the flange to be assembled is transported to the location directly below the hoisting position via the steel trestle 15. The traveling wheels 6 drive the electric hoist 5, the hoisting trolley 7, and the lifting frame 8 to the location above the hoisting position. The electric hoist 5 then lowers the lifting frame 8, which is connected to the flange via a connecting shaft. After the connection is complete, the electric hoist 5 lifts the flange vertically to the installation position. The flange to be assembled is then welded to the main body of the steel bridge 2. After installation, the connection between the lifting frame 8 and the flange is released. When hoisting the flange without the steel trestle 15 below, the flange to be assembled is transported via the steel trestle 15 to the side of the flange installation position with the steel trestle 15 below. The traveling wheels 6 drive the electric hoist 5, the hoisting trolley 7, and the lifting frame 8 to above the flange transport position. The electric hoist 5 operates, lowering the lifting frame 8. The lifting frame 8 is connected to the flange via a connecting shaft. After the connection is completed, the electric hoist 5 operates, vertically lifting the flange to the predetermined height. Then, the traveling wheels 6 of the trolley drive the electric hoist 5, the hoisting trolley 7, and the lifting frame 8 to... The steel bridge flange 1 is transferred to the flange installation position on the side of the steel trestle 15. The electric hoist 5 lowers the steel bridge flange 1 to the assembly height. After the assembled flange is welded to the main body of the steel bridge 2, the connection between the hanger 8 and the flange is released. The installation of the remaining beam segments is carried out by repeating the above steps. It should be noted that the flange on the side of the steel trestle 15 below is hoisted first, and then the flange on the side of the steel trestle 15 below is hoisted to avoid the steel bridge flange 1 installed first interfering with the subsequent installation.
