Description

Technical Field

[0001] This invention belongs to the field of bridge construction technology, specifically relating to a device for preventing derailment of the hanging basket track of a continuous rigid frame bridge. Background Technology

[0002] Cantilever construction is commonly used in bridge construction, and the hanging basket is an important piece of equipment in cantilever bridge construction. The hanging basket has the characteristics of light weight, simple structure, sturdiness and stability, convenient forward movement and disassembly, reusability, and small deformation under stress. In addition, the space under the hanging basket is sufficient to provide a large working surface, which is conducive to the construction of steel reinforcement and formwork.

[0003] During installation, the front and rear supports of the hanging basket are typically placed on a moving device, which is used to move the basket horizontally. The cantilever beam is used to suspend the formwork. After the concrete construction of one segment is completed, the hanging basket is moved forward one construction segment by the moving device to proceed to the next stage of construction. However, the stability and fixing effect of the moving device used with the hanging basket in the existing technology are not good. During the horizontal movement of the hanging basket, there is a problem of easy deviation and derailment, which poses a safety hazard and can easily cause engineering accidents. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a continuous rigid frame bridge hanging basket track anti-derailment device, which solves the problem that the hanging basket is prone to deviation and derailment during translation, which poses safety hazards and is prone to causing engineering accidents.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] The continuous rigid frame bridge hanging basket track anti-derailment device includes track components, the number of track components is four, the four track components are divided into two symmetrical rows, each row includes two track components placed on the same axis, the two track components in each row are close to each other at the near ends and are detachably connected to each other.

[0007] Each track assembly includes a strip-shaped main rail, with a recessed slide rail at the upper end of the main rail along its axial direction. The slide rail passes through both ends of the main rail, and secondary rails are fixed on the outer side walls of both sides of the main rail, placed coaxially with it.

[0008] A horizontally placed connecting strip is located directly above the two track components. The connecting strip is placed perpendicular to the main rail. A fixing frame is fixed to the upper end of the connecting strip, and the hanging basket body is installed on the fixing frame. Sliding components are fixed to both ends of the lower end face of the connecting strip. The two sliding components correspond one-to-one with the two track components. Each track component slides and engages with the corresponding sliding component.

[0009] Each sliding component includes a first slider that is slidably engaged within the slide rail. A fixing plate is fixed to the upper end of each first slider. Connecting strips are fixedly supported on the fixing plate. A pair of support plates are fixed to the end of each fixing plate near the secondary rail. A second slider is fixed to each support plate. The second sliders are slidably engaged with the secondary rail at the corresponding end.

[0010] Each track assembly also includes a pair of straight racks placed coaxially with the secondary rails, with the two racks fixed to the side walls of the main rail near the two secondary rails.

[0011] Each sliding component also includes a pair of rotating shafts rotatably connected to the fixed plate. The rotating shafts are all placed vertically downwards. The rotating shafts are located on both sides of the main rail and correspond one-to-one with the rack. Each rotating shaft is fixedly fitted with a first gear, which meshes with the rack on the corresponding side.

[0012] The length of each rack is less than that of the main rail. Both ends of the rack are flush with the main rail. A first right-angled block is fixed to the flush end of the rack. The inclined end of the first right-angled block is placed away from the rack. A second right-angled block is provided at the other end of the rack. The second right-angled block is slidably engaged with the rack. The second right-angled block is the same size as the first right-angled block. The inclined end of the second right-angled block is placed away from the rack. A rectangular block is fixed to the top of the second right-angled block. The sides of the first and second right-angled blocks away from the main rail are toothed.

[0013] When the inclined ends of any first right-angle block and any second right-angle block are aligned, the first right-angle block and the second right-angle block are spliced ​​together to form a small rack. The sum of the length of the small rack and the length of any straight rack is equal to the length of the main rail. After the two rail components are spliced ​​together, the small rack is spliced ​​with the straight racks at both ends to form a large rack.

[0014] The first right-angle block and the second right-angle block are flush with the side of the main rail, and there is a gap between the side of the second right-angle block and the side wall of the main rail.

[0015] Each of the second right-angle blocks has a mounting plate directly below it. The mounting plates are fixed to the main rail. Each mounting plate has a pair of vertically upward sliding rods. The sliding rods are located in the gap between the second right-angle block and the side wall of the main rail. The sliding rods pass through the rectangular block and are slidably connected to it. Each sliding rod is fitted with a spring. Both ends of the springs are fixed to the mounting plate and the rectangular block, respectively. Before the adjacent track components are spliced, the lower end face of the rectangular block is located between the upper and lower end faces of the straight rack.

[0016] The connecting strip is designed as a hollow shell, and the upper end of the rotating shaft extends into the connecting strip and is rotatably connected to it.

[0017] The sliding components also include a first toothed roller and a second toothed roller disposed inside the connecting strip. The first toothed roller is fixedly sleeved on any rotating shaft, and the second toothed roller is fixedly sleeved on another rotating shaft. A pair of second gears are provided between the first toothed roller and the second toothed roller. The second gears are rotatably connected inside the connecting strip and mesh with each other. One second gear meshes with the first toothed roller, and the other second gear meshes with the second toothed roller. The diameter and number of teeth of the first toothed roller and the second toothed roller are equal.

[0018] The vertical length of the second toothed roller is greater than that of the first toothed roller. The second gear meshes with the lower peripheral wall of the second toothed roller. An annular synchronous toothed belt is sleeved between the second toothed rollers of the two sliding components. The annular synchronous toothed belt meshes with the upper peripheral wall of the second toothed roller. A rotating motor that drives any rotating shaft to rotate is installed on the connecting bar.

[0019] A pair of symmetrically placed ear plates are fixed at both ends of the main rail along its axial direction. The two ear plates at each end are located on both sides of the main rail, and multiple mounting holes are opened on each ear plate.

[0020] Multiple evenly distributed sleeper bars are fixed at the lower end of the main rail. The sleeper bars are placed coaxially with the connecting bars. Both ends of the sleeper bars are threaded with vertically placed screws. The lower ends of the screws pass through the sleeper bars and are fixedly connected with support feet. The upper ends of the screws are fixed with rotating handles.

[0021] The beneficial effects of this invention are:

[0022] 1. The present invention uses a combination of a main rail, a secondary rail, a first slider, a fixed plate, a support plate, and a second slider. The first slider slides and engages with the inner slide of the corresponding column of the track assembly. The secondary rails on both sides of the main rail slide and engage with the second slider, which improves the guiding performance of the sliding assembly during movement. At the same time, the sliding assembly is constrained to prevent deviation during movement and improve the anti-derailment performance.

[0023] Furthermore, by using two detachably connected track components in each column, the relative positions of the two track components in each column only need to be alternated during the entire construction process. This ensures that the sliding components at both ends are always engaged and sliding on the corresponding track components, improving the continuity of construction. Throughout the entire construction process, the first slider always remains engaged with the slide rail, and the second slider always remains engaged with the auxiliary rail. There is no need to repeatedly adjust the positions of the first and second sliders, improving the anti-derailment performance and effectively extending the service life of the first slider, the second slider, and the auxiliary rail.

[0024] 2. The present invention, through the coordinated arrangement of a rack, a shaft, and a first gear, can precisely control the distance the sliding component moves each time by controlling the number of rotations of the first gear. This facilitates the control of the distance the hanging basket body moves each time during bridge construction. At the same time, the meshing of the first gear and the rack further improves the anti-derailment performance.

[0025] 3. The present invention uses the coordinated arrangement of a first right-angle block, a second right-angle block, a rectangular block, a mounting plate, a sliding rod, and a spring. When the sliding component moves to the end of the bridge to be constructed near each track component, the first gear contacts the rectangular block. Through the limiting effect of the rectangular block, the sliding component is prevented from moving excessively and derailing from the track component.

[0026] 4. The present invention, through the coordinated arrangement of the first toothed roller, the second toothed roller, the second gear, the annular synchronous toothed belt, and the rotating motor, enables the first toothed roller and the second toothed roller in the same sliding assembly to maintain a synchronous and opposite rotational movement relationship, and the second toothed rollers in different sliding assemblies to maintain a synchronous and same rotational movement relationship. This facilitates the synchronous movement of the sliding assemblies on both sides, prevents the sliding assemblies on both sides from deviating during movement, and improves the overall anti-derailment performance.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1 to 7 As shown, the continuous rigid frame bridge hanging basket track anti-derailment device includes track assembly 100. There are four track assemblies 100, which are arranged in two symmetrical rows. Each row includes two track assemblies 100 placed coaxially. The two track assemblies 100 in each row are close to each other and are detachably connected.

[0037] Each track assembly 100 includes a strip-shaped main rail 101. The upper end of the main rail 101 is provided with a concave slide along its axial direction. The slide passes through both ends of the main rail 101. A secondary rail 102 is fixed on the outer side wall of both sides of the main rail 101 and is placed in the same axial direction as it.

[0038] A horizontally placed connecting strip 200 is provided directly above the two track assemblies 100. The connecting strip 200 is placed vertically to the main rail 101. A fixing frame 300 is fixed to the upper end of the connecting strip 200. A hanging basket body 400 is installed on the fixing frame 300. Sliding components are fixed to both ends of the lower end face of the connecting strip 200. The two sliding components correspond one-to-one with the two track assemblies 100. Each track assembly 100 is slidably engaged with the corresponding sliding component.

[0039] Each sliding component includes a first slider 501 that is slidably engaged in the slide rail. A fixing plate 502 is fixed to the upper end of each first slider 501. Each connecting strip 200 is fixedly supported on the fixing plate 502. A pair of support plates 503 are fixed to one end of the fixing plate 502 near the sub-rail 102. A second slider 504 is fixed to each support plate 503. The second slider 504 is slidably engaged with the sub-rail 102 at the corresponding end.

[0040] The slide assembly slides and engages with the slide rail in the corresponding column of the track assembly 100 via the first slider 501. This, combined with the sliding engagement of the secondary rails 102 on both sides of the main rail 101 with the second slider 504, improves the guiding performance of the slide assembly during movement. At the same time, it limits and constrains the slide assembly to prevent deviation during movement and improves the anti-derailment performance.

[0041] During use, the main rail 101 is placed along the length of the bridge. The connecting bar 200 and the sliding component are moved along the axis of the main rail 101. The connecting bar 200 drives the fixed frame 300 and the hanging basket body 400, so that the hanging basket body 400 moves to the position where concrete is to be poured. Then, the formwork is built inside the hanging basket body 400 and concrete is poured to carry out bridge construction. After the concrete has solidified, the connecting bar 200 and the sliding component are moved again to the next position to be poured, and the above process is repeated to carry out bridge pouring construction.

[0042] For the convenience of describing this embodiment, the track assembly 100 that is closer to the bridge to be poured in each column of track assembly 100 in the initial state is named the first track assembly 100, and the track assembly 100 that is farther away from the bridge to be poured is named the tail track assembly 100.

[0043] The sliding component moves intermittently multiple times within any main rail 101 to complete multiple continuous bridge construction sections. After the sliding component moves from the tail rail component 100 to the first rail component 100 in any column of track components 100, the tail rail component 100 and the first rail component 100 are disassembled and separated. Then, the tail rail component 100 is moved to the newly poured and solidified bridge surface and its corresponding first rail component 100 is spliced ​​and fixed. As the bridge construction progresses, when the sliding component moves from the first rail component 100 to the tail rail component 100 again, the two rail components 100 in any column of track components 100 are disassembled and separated again. The rail component 100 that is currently away from the part of the bridge to be constructed is moved to a position closer to the part of the bridge to be constructed. At the same time, the two rail components are reassembled and fixed. The above operations are repeated continuously. During bridge construction, when the total length of the bridge section to be poured is greater than the sum of the lengths of any two track components 100, it is not necessary to move the entire construction device. Only the two track components 100 in each row of track components 100 need to be disassembled alternately and repositioned for re-installation. This allows the sliding component to continue moving in any row of track components 100, improving the continuity of construction. Throughout the construction process, the first slider 501 always maintains a sliding engagement with the slide rail, and the second slider 504 always maintains a sliding engagement with the secondary rail 102. There is no need to repeatedly adjust the positions of the first slider 501 and the second slider 504, improving the anti-derailment performance and effectively extending the service life of the first slider 501, the second slider 504, and the secondary rail 102.

[0044] In order to facilitate precise control of the distance the sliding component moves each time, the track assembly 100 also includes a pair of straight racks 103 placed coaxially with the secondary rails 102. The two straight racks 103 are respectively fixed to the side walls of the main rail 101 near the two secondary rails 102.

[0045] Each sliding component also includes a pair of rotating shafts 505 rotatably connected to the fixed plate 502. The rotating shafts 505 are all placed vertically downward. The rotating shafts 505 are located on both sides of the main rail 101 and correspond one-to-one with the rack 103. A first gear 506 is fixedly sleeved on each rotating shaft 505. The first gear 506 meshes with the rack 103 on the corresponding side.

[0046] By driving the rotating shaft 505, the rotating shaft 505 drives the first gear 506, which meshes with the rack 103, causing the first gear 506 to move along the axis of the rack 103. At the same time, the first gear 506 sequentially drives the first rotating shaft 505, the fixed plate 502, and the first slider 501, causing the sliding assembly to move along the axis of the rack 103. The engagement between the rack 103 and the first gear 506 allows for precise control of the distance the sliding assembly moves each time by controlling the number of rotations of the first gear 506. This facilitates control over the distance the hanging basket body 400 moves each time during bridge construction. Furthermore, the meshing of the first gear 506 with the rack 103 further improves the anti-derailment performance.

[0047] In this embodiment, the two track components 100 in each column need to be moved alternately along the bridge pouring end. If the track component 100 far from the pouring part is not disassembled and spliced ​​to the end of the other track component 100 near the pouring part in time, when the sliding component moves excessively, there is a problem that the sliding component may slide off the end of any track component 100 near the pouring part and derail. To solve the above problem, the length of the rack 103 is less than the length of the main rail 101, and both ends of the rack 103 are flush with the main rail 101. One end of each of the flat parts is fixed with a first right-angle block 104. The inclined end of the first right-angle block 104 is placed away from the straight rack 103. The other end of the straight rack 103 is provided with a second right-angle block 105. The second right-angle block 105 is slidably engaged with the straight rack 103. The second right-angle block 105 is the same size as the first right-angle block 104. The inclined end of the second right-angle block 105 is placed away from the straight rack 103. A rectangular block 106 is fixed to the upper end of the second right-angle block 105. The sides of the first right-angle block 104 and the second right-angle block 105 away from the main rail 101 are toothed.

[0048] When the inclined ends of any first right-angle block 104 and any second right-angle block 105 are attached to each other, the first right-angle block 104 and the second right-angle block 105 are spliced ​​together to form a small rack. The sum of the length of the small rack and the length of any straight rack 103 is equal to the length of the main rail 101. After the two rail components 100 are spliced ​​together, the small rack is spliced ​​with the straight racks 103 at both ends to form a large rack.

[0049] When two track components 100 in any column are spliced ​​together, the second right-angle block 105 of one track component 100 is spliced ​​together with the first right-angle block 104 of the other track component 100. At this time, the lower end face of the rectangular block 106 at the splicing position of the two track components 100 is flush with the upper end face of the rack 103. The first right-angle block 104 and the second right-angle block 105 are spliced ​​together to form a small rack. The small rack is spliced ​​together with the racks 103 at both ends to form a large rack. This does not affect the first gear 506 in the sliding component passing through the connection part of the two track components 100.

[0050] When using this invention, the main rail 101 is placed along the length of the bridge, and the rectangular block 106 in each track assembly 100, which is away from the splicing part of the two rails, is located near the end of the bridge to be constructed. The lower end face of the rectangular block 106 is located between the upper and lower end faces of the rack 103. When the sliding assembly moves to the end of each track assembly 100 near the end of the bridge to be constructed, the first gear 506 contacts the rectangular block 106. Through the limiting effect of the rectangular block 106, the sliding assembly is prevented from moving excessively and derailing from the track assembly 100.

[0051] In order to automatically control the movement of the rectangular block 106, so that the rectangular block 106 at the splicing part of the two track components 100 does not interfere with the movement of the sliding component, and at the same time does not affect the limiting function of the rectangular block 106 away from the splicing part of the two track components 100, the side of the first right-angle block 104 and the second right-angle block 105 near the main rail 101 are flush, and a gap is left between the side of the second right-angle block 105 near the main rail 101 and the side wall of the main rail 101.

[0052] Each of the second right-angle blocks 105 is provided with a mounting plate 107 directly below it. The mounting plate 107 is fixed to the main rail 101. Each mounting plate 107 is fixed with a pair of vertically upward sliding rods 108. The sliding rods 108 are located in the gap between the second right-angle block 105 and the side wall of the main rail 101. The sliding rods 108 pass through the rectangular block 106 and are slidably connected to it. Each sliding rod 108 is fitted with a spring 109. Both ends of the spring 109 are fixed to the mounting plate 107 and the rectangular block 106 respectively. Before the adjacent track components 100 are spliced, the lower end face of the rectangular block 106 is located between the upper and lower end faces of the rack 103.

[0053] Before adjacent track components 100 are spliced, the lower end faces of the rectangular blocks 106 are all located between the upper and lower end faces of the rack 103. That is, when two adjacent track components 100 approach each other, the corresponding first right-angle block 104 on any track component 100 and the second right-angle block 105 on the other track component 100 press against each other, causing the second right-angle block 105 at the splicing part of the two track components 100 to move upward along the axis of the slide bar 108. The second right-angle block 105 drives the corresponding rectangular block 106 to move upward. When the first right-angle block 104 and the second right-angle block 105 at the approaching ends of the two track components 100 are... After being fitted together, the lower end face of the rectangular block 106 at the splicing part of the two track components 100 is flush with the upper end face of the rack 103, so that the position of the rectangular block 106 at the splicing part is automatically adjusted when the two track components 100 are spliced, avoiding interference with the movement of the sliding component; at the same time, after splicing, the lower end face of the rectangular block 106 in each row of track components 100 that is far from the splicing part is located between the upper and lower end faces of the rack 103 under the cooperation of the slide rod 108 and the spring 109, which can effectively limit the sliding component and prevent the sliding component from moving excessively and derailing.

[0054] Since the two first gears 506 in the sliding assembly are meshed with the racks 103 on both sides of the main rail 101, when the sliding assembly moves, the first gears 506 on both sides of the same sliding assembly need to rotate synchronously and in opposite directions. The connecting bar 200 is set as a hollow shell, and the upper end of the rotating shaft 505 extends into the connecting bar 200 and is rotatably connected to it.

[0055] Each sliding component also includes a first toothed roller 507 and a second toothed roller 508 disposed inside the connecting strip 200. The first toothed roller 507 is fixedly sleeved on any rotating shaft 505, and the second toothed roller 508 is fixedly sleeved on another rotating shaft 505. A pair of second gears 509 are provided between the first toothed roller 507 and the second toothed roller 508. The second gears 509 are rotatably connected inside the connecting strip 200 and mesh with each other. One second gear 509 meshes with the first toothed roller 507, and the other second gear 509 meshes with the second toothed roller 508. The diameter and number of teeth of the first toothed roller 507 and the second toothed roller 508 are equal.

[0056] By driving any rotating shaft 505 on the sliding assembly, the rotating shaft 505 drives the first toothed roller 507 or the second toothed roller 508 fixedly connected to it. Then, through the transmission of the two second gears 509, the first toothed roller 507 and the second toothed roller 508 in the sliding assembly maintain a synchronous and opposite rotational movement relationship. The second toothed roller 508 and the first toothed roller 507 drive the corresponding rotating shaft 505 and the first gear 506, so that the two first gears 506 in any sliding assembly maintain a synchronous and opposite rotational movement relationship, so that the sliding assembly can effectively move along the rack 103.

[0057] To facilitate synchronous movement of the sliding components on both sides, the vertical length of the second toothed roller 508 is greater than that of the first toothed roller 507. The second gear 509 meshes with the lower peripheral wall of the second toothed roller 508. An annular synchronous toothed belt 601 is sleeved between the second toothed rollers 508 of the two sliding components, and the annular synchronous toothed belt 601 meshes with the upper peripheral wall of the second toothed roller 508. A rotary motor 602 is installed on the connecting bar 200 to drive any rotating shaft 505 to rotate. By turning on the rotary motor 602, the rotary motor 602 drives the corresponding rotating shaft 505. The rotating shaft 505, through the cooperation of the first toothed roller 507, the second toothed roller 508, the second gear 509, and the annular synchronous toothed belt 601, keeps the first toothed roller 507 and the second toothed roller 508 in the same sliding component in a synchronous and opposite rotational direction, and keeps the second toothed rollers 508 in different sliding components in a synchronous and same rotational direction. This facilitates the synchronous movement of the sliding components on both sides, prevents the sliding components on both sides from deviating during movement, and improves the overall anti-derailment performance.

[0058] To facilitate detachable connection between adjacent track assemblies 100, a pair of symmetrically placed ear plates 110 are fixed at both ends of the main rail 101 along its axial direction. The two ear plates 110 at each end are located on both sides of the main rail 101, and multiple mounting holes are provided on each ear plate 110. When adjacent track assemblies 100 are in contact with each other, the ear plates 110 at the corresponding positions are also in contact with each other. The ear edges of the two track assemblies 100 at their closest ends can be connected by fastening bolts, pins, etc., which facilitates subsequent disassembly and reassembly.

[0059] Multiple evenly distributed sleeper bars 701 are fixed to the lower end of the main rail 101. The sleeper bars 701 are placed coaxially with the connecting bar 200. Both ends of the sleeper bars 701 are threaded with vertically placed screws 702. The lower ends of the screws 702 pass through the sleeper bars 701 and are fixedly connected to support feet 703. The upper ends of the screws 702 are fixed with handles. When there are recessed parts on the bridge surface, the screws 702 can be driven by rotating the handles, thereby adjusting the distance between each support foot 703 and the sleeper bar 701, so that each support foot 703 keeps in contact with the bridge surface.
