Description

Technical Field

[0001] This invention relates to the field of concrete canopy hoisting technology, specifically to an integrated hoisting equipment and process for a double-column concrete canopy of a railway passenger station. Background Technology

[0002] Previously, railway passenger station platform canopies were mainly constructed using steel structures (space frame and membrane structures) and cast-in-place concrete structures. Steel structure canopies suffer from drawbacks such as susceptibility to rust, poor wind resistance, and severe vibrations and noise from passing trains. Cast-in-place concrete structure canopies, on the other hand, require significant manpower for frequent pouring of various formwork, involve numerous overlapping operations with station front work, and require substantial scaffolding for single-layer structures, resulting in complex construction and high overall costs.

[0003] Currently, there is a type of prefabricated concrete canopy component, which is manufactured in advance and transported to the site for assembly, saving on-site construction costs. On-site, wheeled or crawler cranes are mainly used for hoisting along the tracks on the platform side. Each span requires moving and positioning the crane, resulting in lengthy relocation and hoisting times, a large hoisting radius, and heavy double-column canopy roof components (some middle slabs weigh up to 40 tons), requiring large cranes and resulting in low hoisting efficiency. The hoisting route is constrained by the subgrade conditions, requiring full cooperation from the subgrade construction units. Even if the subgrade units permit the use, there are still cross-operations that can affect the overall project schedule. Without dismantling the existing track or using dedicated railcars for transportation or rail hoisting, this method cannot be implemented. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, this invention proposes an integrated hoisting equipment and process for a concrete double-column canopy of a railway passenger station. This application can make reasonable use of the space of the platform, i.e., the platform roof, without occupying the railway line foundation, and has a shorter construction period and lower construction cost.

[0006] The technical solution of the present invention is as follows:

[0007] An integrated hoisting device for a concrete double-column canopy of a railway passenger station includes: a main beam, a front support, a middle support, and a rear support. There are two front supports, two middle supports, and two rear supports, symmetrically arranged on both sides of the main beam in a front-to-back order. The middle support is retractable and mounted on the main beam. A longitudinal rail is provided along the extension direction of the main beam. A movable vertical rail is provided on the side of the longitudinal rail away from the main beam. A movable lifting trolley is provided on the side of the vertical rail away from the longitudinal rail. There are at least two lifting trolleys. The rear support is erected on the hoisted vertical rail beam. Adjacent canopy columns on which the vertical rail beam is installed are fixed together by reinforcing beams.

[0008] Furthermore, the width of the two front supports is greater than the width of the outermost two parallel canopy columns, and there are two vertical tracks, with two lifting trolleys installed on each vertical track.

[0009] Furthermore, the bottom of the front support is equipped with a movable electric vehicle wheel.

[0010] Furthermore, the rear support is movable on the main beam track.

[0011] Furthermore, the front support, the middle support, and the rear support are all equipped with height-adjustable hydraulic devices.

[0012] The hoisting process of the aforementioned integrated hoisting equipment for a railway passenger station concrete double-column canopy includes the following steps: S1: The canopy columns are installed on the foundation platform using spigot and socket joints, and the canopy foundation is backfilled to the elevation of the foundation platform surface; S2: After assembling the hoisting equipment, the rear support of the hoisting equipment is placed on the top of the first vertical rail beam after hoisting, and the front support is placed on the backfill surface of the third span foundation platform. S3: The canopy columns, vertical rail beams, roof middle panels and roof side panels to be hoisted are transported to the hoisting position through the middle of the two canopy columns in sequence, and then hoisted in sequence; S4: After the canopy columns, vertical rail beams, roof middle panels and roof side panels in S3 are hoisted in sequence, the middle support is erected on the vertical rail beam, the rear support is moved forward to the support position of the middle support, the middle support is retracted, the rear support position is kept still, and the main beam frame moves forward to the next span synchronously with the front support. S5: Repeat steps S3-S4 above to hoist the next span.

[0013] Furthermore, after the canopy columns are installed at the insertion interface, adjacent canopy columns are fixedly connected by reinforcing beams. The canopy foundation is backfilled to the elevation of the foundation platform surface, and the backfilled canopy foundation is capable of supporting heavy-duty vehicles.

[0014] Furthermore, the hoisting equipment has two lifting trolleys, which are respectively suspended at different positions on the vertical rail beam. The positions of the lifting trolleys can be adjusted arbitrarily through the vertically set vertical and longitudinal rails.

[0015] Further, in step S3, the vertical rail beam to be hoisted is transported to the hoisting location, and the vertical rail beam is hoisted by the hoisting trolley of the hoisting equipment. The hoisting height of the vertical rail beam is higher than that of the canopy column. The vertical rail beam is rotated 90° in the air and then moved. After the vertical rail beam is moved to the hoisting position, it is lowered and fixed.

[0016] Further, in step S3, the roof side panels on both sides are hoisted respectively. After the roof side panels on both sides are hoisted, the next vertical rail beam is hoisted. The vertical rail beam to be hoisted is transported to the hoisting position, and the vertical rail beam is hoisted by the hoisting trolley of the hoisting equipment. The hoisting height of the vertical rail beam is higher than that of the canopy column. After the vertical rail beam is moved to the hoisting position, it is lowered and fixed.

[0017] The present invention can achieve the following beneficial effects: The integrated hoisting equipment for a railway passenger station concrete double-column canopy according to the present invention includes: a main beam, a front support, a middle support, and a rear support. There are two front supports, two middle supports, and two rear supports. This equipment allows for rail transport or hoisting without dismantling the track or using a dedicated railcar, and is not constrained by the subgrade or requires cooperation from the construction unit. The front support, middle support, and rear support are all equipped with hydraulic devices for height adjustment, ensuring the frame remains level. The device has two lifting trolleys, enabling dual-point hoisting to ensure flatness and higher positioning accuracy. After the vertical rail beam is hoisted, the canopy columns are temporarily fixed to meet the strength and rigidity requirements for hoisting the roof slab and side panels, ensuring the construction period is met.

[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] The following is a reference appendix. Figures 1a to 4d This invention describes an integrated hoisting device and method for a double-column concrete canopy of a railway passenger station according to an embodiment of the present invention. Figures 1a-1d The diagrams from left to right depict the hoisting of the canopy columns, the rear support, the crane trolley operation, and the front support. Figures 2a-2dThe diagram shows the hoisting of the vertical rail beam, the rear support, the working of the crane trolley, and the front support. Figures 3a-3d The diagram shows the working process of the roof slab, the rear support, the hoisting trolley, and the front support. Figures 4a-4d The diagrams show the hoisting of the roof side panels, the rear support, the operation of the crane trolley, and the front support.

[0023] like Figures 1a-4d As shown in the figure, this invention discloses an integrated hoisting device for a concrete double-column canopy of a railway passenger station. The device includes a main beam 1, a front support 2, a middle support 3, and a rear support 4. There are two of each of the front support 2, middle support 3, and rear support 4, symmetrically arranged on the main beam 1 in a front-to-back order. The middle support 3 is retractable on the main beam 1. A longitudinal track is provided along the extension direction of the main beam. A movable vertical track 5 is provided on the side of the longitudinal track away from the main beam 1. A movable lifting trolley 6 is provided on the side of the vertical track 5 away from the longitudinal track. There are at least two lifting trolleys 6. The rear support 4 is erected on the hoisted vertical rail beam 20. Adjacent canopy columns 10 of the vertical rail beam 20 are fixed together by reinforcing beams 7. With this device, track transportation or hoisting can be achieved without dismantling the track or using a dedicated railcar, and it is not constrained by the subgrade or requires the cooperation of the subgrade construction unit. The device is equipped with two lifting trolleys 6, which can ensure the flatness of the hoisting and the accuracy of the positioning through dual-point hoisting.

[0024] Furthermore, the width of the two front supports 2 is greater than the width of the outermost two parallel canopy columns 10, ensuring that the hoisting equipment is not obstructed during its forward movement.

[0025] In another embodiment, there are two vertical tracks 5, and two lifting trolleys 6 are provided on each vertical track 5. By adopting four-point hoisting, the roof panel has good flatness and higher positioning accuracy.

[0026] In some embodiments, the bottom of the front support 2 is equipped with movable electric wheels to facilitate rapid movement of the ground support.

[0027] Furthermore, the rear support 4 can move on the track of the main beam 1, which facilitates the separation of the rear support 4 from the vertical rail beam 20 and enables the movement of the hoisting equipment.

[0028] In some embodiments, the front support 2, the middle support 3, and the rear support 4 are all equipped with hydraulic devices, which can adjust the height of the supports to keep the frame horizontal and stable.

[0029] Furthermore, the intermediate support 3 is connected to the main beam 1 through a rotating fixing assembly, wherein the rotating fixing assembly can be an electric rotating fixing assembly, a pneumatic rotating fixing assembly, a hydraulically driven rotating fixing assembly, etc.

[0030] like Figures 1a-4d As shown in the figure, this invention discloses an integrated hoisting process for a concrete double-column canopy of a railway passenger station, characterized by the following steps: S1: The canopy column 10 is installed on the foundation platform using the socket 8, and the canopy foundation is backfilled to the elevation of the foundation platform surface; S2: After assembling the hoisting equipment, the rear support 4 of the hoisting equipment is erected on the top of the first vertical rail beam 20 after hoisting, and the front support 2 is erected on the backfill surface of the third span foundation platform. S3: The canopy columns 10, vertical rail beams 20, roof middle panels 30 and roof side panels 40 to be hoisted are transported to the hoisting position through the middle of the two canopy columns 10 in sequence, and then hoisted in sequence. S4: After the previous set of canopy columns 10, vertical rail beams 20, roof middle plate 30 and roof side plate 40 are hoisted in sequence, the middle support 3 is erected on the vertical rail beam, the rear support 4 is moved forward to the erection position of the middle support 3, the middle support 3 is retracted, the rear support 4 is kept in place, and the main beam 1 and the front support 2 are moved forward to the next span simultaneously. S5: Repeat steps S3-S4 above to hoist the next span.

[0031] Further, in step S1: after the canopy column 10 is installed in the insertion interface 7, it is connected and fixed to the adjacent canopy column 10 that has already reached the design strength using the foundation cup plug and the reinforcing beam 7. Grouting is carried out after all the roof side panels and roof middle panels are hoisted. After the grouting reaches the design strength, the temporary reinforcing beam is removed.

[0032] After the canopy column 10 is installed, the canopy foundation is backfilled to the elevation of the foundation platform surface, and the backfilled canopy foundation is capable of supporting heavy-duty vehicles.

[0033] Furthermore, after the vertical beam 20 is hoisted, the roof middle plate 30 needs to be hoisted, followed by the roof side plate 40. The specific steps are as follows: After the vertical beam 20 is firmly fixed, the roof middle plate 30 is transported to the hoisting mid-span position through the middle of the double-column canopy. Then, the roof middle plate 30 is delivered to the design position through hoisting, lateral movement, retraction, and lateral movement again. The roof middle plate 30 is then lowered into place, and then the roof side plate 40 is hoisted.

[0034] Furthermore, when hoisting the canopy columns 10, vertical rail beams 20, roof side panels 30, and roof middle panels 40, the transportation channel is the middle of the canopy double columns, and the foundation platform elevation can bear the backfill surface.

[0035] Furthermore, the vertical rail beam 20 is lifted by the lifting trolley 6 of the hoisting equipment. There are two lifting trolleys 6, each suspended at a different position on the vertical rail beam 20. The positions of the lifting trolleys 6 can be adjusted using the vertically arranged vertical rails 5 and the longitudinal rails.

[0036] In some embodiments, in step S3, after the vertical rail beam is lifted, it needs to be rotated 90° in the air before being moved. The vertical rail beam to be lifted is transported to the lifting position, and the vertical rail beam is lifted by the lifting trolley of the lifting equipment. The lifting height of the vertical rail beam is higher than that of the canopy column. The vertical rail beam is rotated 90° in the air before being moved. After the vertical rail beam is moved to the lifting position, it is lowered and fixed.

[0037] In some embodiments, in step S3, the roof side panels on both sides are hoisted respectively. After the roof side panels on both sides are hoisted, the next vertical rail beam is hoisted. The vertical rail beam to be hoisted is transported to the hoisting position, and the vertical rail beam is hoisted by the hoisting trolley of the hoisting equipment. The hoisting height of the vertical rail beam is higher than that of the canopy column. After the vertical rail beam is moved to the hoisting position, it is lowered and fixed.

[0038] Overall hoisting process of double-column canopy: Equipment assembly (rear support 4 is erected on top of the first vertical rail beam after hoisting, front support 2 is erected on the backfill surface of the third span foundation platform) → the rear canopy column 10 of the hoisting span is transported to the hoisting position → the canopy column 10 is hoisted and inserted into the pre-made leveling pad stone strip → after the canopy column 10 is aligned, it is first secured around the cup opening with wooden plugs → the top of the canopy column 10 is connected and fixed to the adjacent installed canopy column 10 using the reinforcing beam 7 → the middle vertical rail beam is transported to the hoisting position → the vertical rail beam is hoisted, and after the hoisting height is higher than the top of the canopy column 10, it is moved to the middle of the frame span → the vertical rail beam is rotated 90 degrees in the air → after moving along the rail to the hoisting position, the beam is lowered into place and fixed → the roof middle plate 30 is transported to the hoisting position → after hoisting the roof middle plate 30, the load is moved inward along the vertical rail direction to the middle of the span → the load is moved along the vertical rail direction to the middle of the span. After moving the load along the track to the hoisting position, it is lowered and installed. → The roof side panel 40 on one side of the span is transported to the hoisting position. → After hoisting, the load is moved along the track to the middle of the hoisting span. → The load is moved to the hoisting position and lowered. → The roof side panel 40 on the other side of the span is transported to the hoisting position. → After hoisting, the load is moved along the track to the middle of the hoisting span. → The load is moved to the hoisting position and lowered. → The next vertical rail beam is transported to the hoisting position. → The canopy column 10 is installed in the next span. → The vertical rail beam 20 is installed in the next span. → The middle support 3 is lowered so that it supports the vertical rail beam 20. → The rear support 4 is retracted and moved forward to the middle support 3 so that the rear support 4 supports the vertical rail beam 20. → The middle support 3 is retracted. → The rear support 4 remains stationary, and the main beam 1 and the front support 2 are moved forward synchronously to the next span for hoisting.
