Description

Technical Field

[0001] The present application relates to the technical field of bridge demolition operations, and in particular to a hanging basket mobile system. Background Art

[0002] The demolition construction of old bridges generally follows the reverse process of the construction of new bridges. For variable-section continuous beam bridges that were built with a hanging basket on the original bridge, the more commonly used demolition method is to use a hanging basket to lift and lower the pieces for demolition or to use large lifting equipment to directly lift and lower the pieces for demolition. For variable-section continuous beam bridges across waterways, since they cross the existing waterway below, their demolition process has a greater impact on the passage of the waterway, and the demolition operation is often carried out by lowering the pieces using a hanging basket.

[0003] The existing old bridge demolition basket equipment is a diamond-shaped basket demolition and lowering equipment, which is mainly composed of three parts: the bridge hanger, the winch pulley group, and the anchoring device. The bridge hanger is designed as a diamond truss, and the main load-bearing rods are steel pipes + steel sections welded or bolted. In addition, the diamond-shaped basket equipment takes a long time to dismantle the variable-section continuous beam bridge across the waterway because it is necessary to anchor the rear anchor equipment and move the basket equipment as a whole within the closure period. When constructing a bridge across the waterway, the closure time given by the waterway department is generally short. If the scheduled construction task cannot be completed within the specified time, it is generally necessary to postpone it to the next closure period. Multiple closures will lead to a longer overall construction period and have a greater impact on the passage of the waterway. Summary of the invention

[0018] 1. In the hanging basket moving system of the present application, after hoisting a single bridge segment, the Bailey frame beam can be quickly moved directly through the first power mechanism, and then the next bridge segment can be hoisted immediately. Compared with the existing original diamond hanging basket, it can save about half of the construction period, with high construction efficiency, convenient construction operation, short construction time, reduced number of navigation closures and occupation time of the waterway, and little impact on the navigation of the waterway.

DETAILED DESCRIPTION

[0025] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be interpreted as limiting the present application.

[0026] See also Figure 1 and Figure 2 In order to solve the problems that the existing hanging basket diamond truss has large construction workload, long construction time and is not conducive to turnover use, the present application provides a mobile Bailey frame hanging basket, which includes a Bailey frame longitudinal beam 1, a Bailey frame cross beam 2, a hoisting mechanism 4 and a hanging basket moving system. The Bailey frame longitudinal beam 1 and the Bailey frame cross beam 2 are both assembled Bailey frame structures, which are simple to assemble, easy to use and save construction costs.

[0027] Specifically, the Bailey frame longitudinal beam 1 extends along the longitudinal bridge direction, the Bailey frame cross beam 2 extends along the cross bridge direction, and the Bailey frame cross beam 2 is vertically located above the Bailey frame longitudinal beam 1 , and the hoisting mechanism 4 is disposed on the Bailey frame cross beam 2 .

[0028] The Bailey frame longitudinal beam 1 includes multiple rows of transverse Bailey beams 11 arranged side by side along the transverse bridge direction, two adjacent rows of transverse Bailey beams 11 are arranged at a preset distance, and a scissors brace 12 and a flat joint 13 are arranged between the two adjacent rows of transverse Bailey beams 11. Preferably, the Bailey frame longitudinal beam 1 in this embodiment is arranged in 5 rows along the transverse bridge direction, and the distance between the two adjacent rows of transverse Bailey beams 11 is 45 cm. Each row of transverse Bailey beams 11 includes an upper chord 111, a lower chord 112 and a web 113, and the web 113 is obliquely arranged between the upper chord 111 and the lower chord 112. Specifically, the upper chord 111 and the lower chord 112 are provided with two web members 113 at the same height direction, the ends of the two web members 113 are connected and the inclination directions are opposite, and the inclination directions of the two adjacent web members 113 along the length direction of the Bailey frame longitudinal beam 1 are also opposite and the ends are connected, so that the web members 113 are arranged in a diamond structure and a plurality of them are arranged between the upper chord 111 and the lower chord 112 along the longitudinal bridge direction.

[0029] Furthermore, a support rod 114 is provided between two adjacent rhombus-shaped web members 113 . The support rod 114 extends in a vertical direction and two ends thereof are respectively fixed to the upper chord 111 and the lower chord 112 .

[0030] In addition, the Bailey frame longitudinal beam 1 is provided with a web bar 113 near the lower lifting support position, and a top support rod 115 is provided at the cross position. The top support rod 115 is used to support the upper chord rod 111 and the lower chord rod 112, so as to strengthen the structure of the Bailey frame longitudinal beam 1 and ensure that the force of the Bailey frame longitudinal beam 1 meets the construction requirements. Preferably, the top support rod 115 is made of double-jointed 10a channel steel, and the two ends of the top support rod 115 are polished. The two ends of the top support rod 115 are non-fixedly connected to the upper chord rod 111 and the lower chord rod 112. Before lifting, the top support rod 115 can be clamped between the upper chord rod 111 and the lower chord rod 112, which is convenient for installation and disassembly.

[0031] In addition, the Bailey frame longitudinal beam 1 is divided into a plurality of longitudinal beam sections along its length direction (not marked in the figure, the same below), and the connection between two adjacent longitudinal beam sections is detachable, which can be fixed by bolts. At the same time, each longitudinal beam section can adopt a prefabricated structure, so that different numbers of longitudinal beam sections can be selected according to construction needs to be assembled on site to form Bailey frame longitudinal beams 1 of different lengths.

[0032] The Bailey frame crossbeam 2 is provided with multiple rows of transverse Bailey frames 21 along the transverse bridge direction. Preferably, the transverse Bailey frames 21 in this embodiment are provided with six rows, and the six rows of transverse Bailey frames 21 are divided into three groups in pairs, and the spacing between two adjacent groups of transverse Bailey frames is 30 cm. Among them, the two rows of transverse Bailey frames 21 in the two groups of transverse Bailey frames 21 on both sides are arranged at a spacing of 45 cm, and the two rows of transverse Bailey frames 21 in the middle are arranged at a spacing of 90 cm, and a scissor brace 22 and a flat joint 23 for connecting the two rows of transverse Bailey frames 21 in each group of transverse Bailey frames 21 are provided.

[0033] In addition, it should be noted that the spacing between the multiple rows of transverse Bailey frames 21 of the Bailey frame beam 2 of the present application can be adjusted according to the construction force requirements, and the arrangement of the multiple rows of transverse Bailey frames 21 should be symmetrically arranged around the longitudinal center axis of the Bailey frame beam 2.

[0034] Each row of transverse Bailey frames 21 includes an upper chord 211, a lower chord 212, a web member 213 and a support rod 214 arranged therebetween. The web member 213 is partially inclined and arranged in a diamond-shaped structure between the upper chord 211 and the lower chord 212. Both ends of the support rod 214 are fixed to the upper chord 211 and the lower chord 212 respectively.

[0035] At the same time, each row of Bailey frame beams 2 can also be divided into multiple beam sections along its length direction (not marked in the figure, the same below), and the adjacent beam sections are detachably connected, which can be fixed by bolts. At the same time, each beam section can adopt a prefabricated structure, so that different numbers of beam sections can be selected for on-site assembly according to the construction length requirements of the Bailey frame beams 2.

[0036] The hanging basket moving system includes a beam moving track 31 arranged between the Bailey frame longitudinal beam 1 and the Bailey frame cross beam 2. The beam moving track 31 extends along the length direction of the Bailey frame longitudinal beam 1. The bottom of the Bailey frame cross beam 2 is provided with a slider 24 that is adapted to and can slide relatively with the beam moving track 31. The Bailey frame cross beam 2 is connected to a first power mechanism (not shown in the figure, the same below) for pulling it to move along the beam moving track 31.

[0037] Preferably, the first power mechanism adopts a 5t hand chain hoist, which rotates by pulling the manual chain and the hand chain wheel, pressing the friction plate ratchet and the brake seat into one and rotating together. The tooth major axis causes the plate gear, tooth minor axis and spline hole gear to rotate, so that the lifting sprocket installed on the spline hole gear drives the lifting chain, thereby smoothly pulling the heavy object. At the same time, the hand chain hoist adopts a ratchet friction plate one-way brake, which can brake itself under load. The ratchet engages with the ratchet under the action of the spring, and the brake works safely.

[0038] In addition, a limiter (not shown in the figure, the same below) is set at the front and rear of the bottom of the slider 24 during the lifting work. The limiter is used to limit the movement of the slider 24 along the beam moving track 31, and then the limiter can be used to stop the slider 24 during the lifting process to ensure the stability of the Bailey frame beam 2 during the lifting process. The limiter is a steel wedge inserted at the front and rear of the bottom of the slider 24.

[0039] In a preferred embodiment, two sets of Bailey frame longitudinal beams 1 are arranged side by side along the transverse bridge direction, and the two sets of Bailey frame longitudinal beams 1 are respectively located on both sides of the bridge deck and are respectively connected to the two ends of the Bailey frame cross beam 2. At the same time, a set of cross beam moving tracks 31 is respectively arranged at both ends of the Bailey frame cross beam 2 corresponding to the two sets of Bailey frame longitudinal beams 1, and each set of cross beam moving tracks 31 is arranged corresponding to one set of Bailey frame longitudinal beams 1, and each set of cross beam moving tracks 31 includes two rows of cross beam moving tracks 31 arranged side by side along the transverse bridge direction, and a set of sliders 24 is respectively arranged at both ends of the Bailey frame cross beam 2 corresponding to the two sets of cross beam moving tracks 31, and each set of sliders 24 is provided with two, so that the Bailey frame cross beam 2 moves along the longitudinal bridge direction through the sliders 24 and the cross beam moving tracks 31 in one-to-one cooperation.

[0040] Furthermore, each set of sliders 24 is connected to the same connecting beam 25 and connected to the Bailey frame beam 2 through the connecting beam 25 to ensure the consistency of movement of the two sliders 24. In addition, the bottom of both ends of the Bailey frame beam 2 corresponding to the position of the connecting beam 25 is also provided with a load-bearing beam 26 extending along the longitudinal bridge direction.

[0041] A first cushion beam 14 is provided between the top of the Bailey frame longitudinal beam 1 and the cross beam moving track 31. The first cushion beam 14 extends in the transverse direction and multiple beams are arranged along the length direction of the Bailey frame longitudinal beam 1. The first cushion beam 14 is used to increase the pressure-bearing area between the cross beam moving track 31 and the Bailey frame longitudinal beam 1.

[0042] The basket moving system also includes a longitudinal beam moving track 32 arranged at the bottom of the Bailey frame longitudinal beam 1 and extending along its length direction. The Bailey frame longitudinal beam 1 is connected to a second power mechanism (not shown in the figure, the same below) for pulling it to move along the longitudinal beam moving track 32, thereby realizing the overall movement of the entire Bailey frame basket along the longitudinal bridge direction.

[0043] Furthermore, two rows of longitudinal beam moving tracks 32 arranged side by side in the transverse direction of the bridge are provided corresponding to the same Bailey frame longitudinal beam 1. The two rows of longitudinal beam moving tracks 32 are symmetrical with the transverse central axis of the Bailey frame longitudinal beam 1, and a load-bearing leg 15 is provided between the bottom of the Bailey frame longitudinal beam 1 and the two rows of longitudinal beam moving tracks 32. The load-bearing leg 15 extends in the transverse direction of the bridge, and a plurality of the load-bearing legs 15 are arranged side by side in the longitudinal direction of the bridge. At the same time, a second cushion beam 321 extending in the transverse direction of the bridge is provided at the bottom of the longitudinal beam moving track 32, so as to adjust the longitudinal beam moving track 32 to be located at the same height position, and to increase the pressure-bearing area of ​​the longitudinal beam moving track 32. In addition, when the second cushion beam 321 is located at an uneven bridge surface, mortar can be used for leveling.

[0044] Preferably, the longitudinal beam moving rail 32 and the second cushion beam 321 in this embodiment are both made of 25# steel. In addition, when the Bailey frame longitudinal beam 1 is loaded and hoisted, the gap between the longitudinal beam moving rails 32 should be filled with 25# steel.

[0045] In addition, the second power mechanism includes a hydraulic jack, and the load-bearing legs 15 of the Bailey frame longitudinal beam 1 are provided with a moving steel strand and an anchor, so that the steel strand is pulled by the hydraulic jack to achieve the movement of the Bailey frame longitudinal beam 1. In addition, the longitudinal beam moving tracks 32 of the left and right sets of Bailey frame longitudinal beams 1 of the Bailey frame cross beam 2 are also provided with scales (not shown in the figure, the same below) to ensure the synchronization of the movement of the left and right sets of Bailey frame longitudinal beams 1.

[0046] Furthermore, the longitudinal beam moving track 32 includes multiple track sections along its length direction (not marked in the figure, the same below), and the adjacent track sections are detachably connected, so that after the Bailey frame longitudinal beam 1 moves forward, the vacant track section can be detached and reinstalled to the end of the track section in front of the moving direction of the Bailey frame longitudinal beam 1, thereby realizing the alternating and cyclic use of the track sections.

[0047] The hoisting mechanism 4 is arranged on the Bailey frame cross beam 2, and moves along the cross beam moving track 31 through the Bailey frame cross beam 2 to drive the hoisting mechanism 4 to move along the Bailey frame longitudinal beam 1, so that the bridge blocks can be hoisted section by section along the longitudinal bridge direction.

[0048] A crane beam 44 extending in the longitudinal direction of the bridge is provided above the Bailey frame cross beam 2. A hoisting mechanism 4 is provided on the crane beam 44. The hoisting mechanism 4 includes a winch 41, a pull rope 42 and a pulley block 43. The pull rope 42 is wound around the pulley block 43 and pulls the bridge segment through the winch 41.

[0049] Preferably, the pulley block 43 of this embodiment includes 6 fixed pulleys and 6 movable pulleys, and the lifting power of the winch 41 is 8T, so the overall lifting capacity of the hoisting mechanism 4 can reach 96T. At the same time, the hoisting mechanism 4 is provided with two groups along the transverse bridge direction, and the two groups of hoisting mechanisms 4 are symmetrically arranged with the transverse central axis of the Bailey frame beam 2, so the lifting capacity of the mobile Bailey frame hanging basket of this embodiment can reach 192T.

[0050] At the same time, in order to ensure the stability of the lifting process, a rear anchor mechanism 5 anchored to the bridge segment is provided on the side of the Bailey frame longitudinal beam 1 away from the lifting mechanism 4 to prevent the Bailey frame longitudinal beam 1 from moving during the lifting of the bridge segment and causing the entire Bailey frame basket to overturn, thereby ensuring the safety of the bridge segment lifting process.

[0051] There are multiple groups of rear anchor mechanisms 5, and the multiple groups of rear anchor mechanisms 5 are anchored in sequence to different consecutive bridge segments. Preferably, there are three groups of rear anchor mechanisms 5 in this embodiment, and the three groups of rear anchor mechanisms 5 are connected to three consecutive bridge segments in sequence to ensure the safety of the Bailey frame longitudinal beam 1 for hoisting the bridge segment. At the same time, when hoisting the current bridge segment, the rear anchor mechanisms 5 of the next two bridge segments need to be anchored at the same time to facilitate subsequent anchor replacement.

[0052] Each group of rear anchor mechanism 5 includes a shoulder pole beam 51 and fine-rolled threaded steel 52 arranged on the crossbeam moving track 31. The shoulder pole beam 51 extends along the longitudinal direction of the bridge and preferably adopts double-jointed 20a I-shaped steel. The fine-rolled threaded steel 52 is passed through the shoulder pole beam 51. At the same time, the fine-rolled threaded steel 52 passes through the Bailey frame longitudinal beam 1 and extends to the bridge block section for anchoring. Preferably, the fine-rolled threaded steel 52 adopts Φ32mm fine-rolled threaded steel, and three groups of fine-rolled threaded steel 52 are arranged along the longitudinal direction of the bridge, and the two adjacent groups of fine-rolled threaded steel 52 are arranged at an interval of 25cm. Furthermore, in order to ensure the overall stability of the Bailey frame longitudinal beam 1, a rear anchor beam 53 extending along the transverse direction of the bridge is arranged between the shoulder pole beam 51 and the Bailey frame longitudinal direction. Preferably, the rear anchor beam 53 adopts double-jointed 45a I-shaped steel.

[0053] In addition, it should be noted that the model and size of the profiles used in this application can be selected according to specific construction requirements and are not limited to the models and sizes specified in this embodiment.

[0054] The present application also relates to a moving method of the above-mentioned hanging basket moving system, which specifically comprises the following steps:

[0055] When the Bailey frame beam 2 needs to move in the longitudinal direction, the Bailey frame beam 2 is pulled by the first power mechanism, and the slider 24 slides on the slider moving track 31 to realize the longitudinal movement of the Bailey frame beam 2. Before the Bailey frame beam 2 moves, a reaction device needs to be temporarily welded on the longitudinal moving track 32 to ensure the stability of the overall structure of the mobile Bailey frame hanging basket during the movement of the Bailey frame beam 2. After the Bailey frame beam 2 moves into place, it is limited and stopped by the limit pieces at the front and rear of the bottom of the slider 24.

[0056] When the Bailey frame longitudinal beam 1 needs to move along the longitudinal bridge, the Bailey frame longitudinal beam 1 is pulled by the second power mechanism, so that the Bailey frame longitudinal beam 1 moves along the longitudinal beam moving track 32, and then the overall movement of the mobile Bailey frame hanging basket can be realized. At the same time, before the Bailey frame longitudinal beam 1 moves, a reaction device needs to be temporarily welded on the longitudinal beam moving track 32 to ensure the stability of the Bailey frame longitudinal beam 1 during the movement process.

[0057] Therefore, when the mobile Bailey frame hanging basket of the present application is used for the demolition of an old bridge, the bridge is first divided according to the preset size, and before the block cutting, the pull rope 42 of the lifting mechanism 4 is used to connect, so as to lift the cut bridge block, and after the cutting of the bridge block is completed, the winch 41 is started to lower the bridge block to the in-place barge, so as to realize the lifting and demolition of the old bridge span by span.

[0058] After each bridge segment is hoisted, the Bailey frame beam 2 can be pulled by the hand winch to move to the corresponding next bridge segment hoisting position, and the slider 24 slides on the beam moving track 31. When the Bailey frame beam 2 is in place, the limit pieces at the bottom and front of the slider 24 are used to limit and stop. Then, the pull rope 42 of the hoisting mechanism 4 is used to connect the bridge segment to be cut, and the above steps are repeated until the old bridge is dismantled.

[0059] After the lifting and removal of two bridge blocks are completed, the Bailey frame longitudinal beam 1 is moved along the longitudinal beam moving track 32 in the longitudinal direction of the bridge to move the mobile Bailey frame basket as a whole. First, the longitudinal beam moving track 32 needs to be connected and extended, and a reaction device is temporarily welded on the connected longitudinal beam moving track 32. The steel strands and anchors for movement are passed through the load-bearing legs 15 of the Bailey frame longitudinal beam 1, and then the hydraulic jack is started to move the Bailey frame longitudinal beam 1 to realize the overall movement of the mobile Bailey frame basket. After the Bailey frame longitudinal beam 1 is moved into place, the rear anchor mechanism 5 is used to re-anchor the Bailey frame.

[0060] It should also be noted that the longitudinal beam moving track 32 should be scaled in advance to ensure the synchronization of the movement of the Bailey frame longitudinal beam 1 at both ends of the Bailey frame cross beam 2, and a special person should be designated to check the stability during the movement. Once an abnormal situation occurs, the construction should be stopped in time and the movement can only be continued after the problem is solved.

[0061] In addition, the track section of the longitudinal beam moving track 32 vacated when the Bailey frame longitudinal beam 1 moves can be reused and connected to the front end of the longitudinal beam moving track 32 to achieve cyclic alternating use and save waste of profiles.

[0062] If the mobile Bailey frame hanging basket of the present application is used for bridge construction, the moving direction of the mobile Bailey frame is opposite to the moving direction of the bridge demolition mentioned above. At the same time, an operating platform needs to be configured at the front end of the hanging basket for assembling and pouring beam sections.

[0063] In summary, the mobile Bailey frame hanging basket of the present application is modified on the original diamond hanging basket dismantling equipment, and the original hanging basket diamond truss is changed to a truss assembled by using a standard Bailey frame, the quality is controllable, the force safety is more guaranteed, and after the bridge is dismantled, the equipment can be used in a turnover manner, reducing the construction cost. At the same time, after dismantling a single bridge block, the hanging basket mobile system of the present application can directly realize the rapid movement of the Bailey frame beam 2 and the lifting mechanism 4 through a hand winch, and then immediately dismantle the next bridge block. Compared with the existing original diamond hanging basket, it can save about half the construction period, with high construction efficiency, convenient construction operation, short construction time, reduced number of closures and occupation time of the waterway, and little impact on the navigation of the waterway.

[0064] The above are only some implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
