Description

Technical Field

[0001] This application relates to the technical field of methods or equipment specifically for erecting or assembling bridges, and specifically to an integrated construction platform for transporting and lifting bridge girder modules. Background Technology

[0002] In urban bridge construction, the erection of cantilever bridge cap beams on existing busy highways presents significant challenges due to traffic disruptions and safety risks when the cap beam supports and formwork are placed on the existing road surface. Traditionally, the construction of cantilever bridge cap beams in urban bridges involves either using a full-span scaffold with pre-reserved openings for formwork erection and concrete pouring, or using large steel pipe Bailey scaffolds for rebar tying, formwork erection, and concrete pouring. These methods typically require traffic closure or diversion for 3-5 days during scaffold and opening construction. Traffic is reopened after scaffolding erection and cap beam construction, but the hoisting of rebar and formwork, as well as concrete pouring, must be carried out over the existing traffic. Although protective canopies exist, the safety risks remain substantial. Similarly, dismantling the scaffolding requires traffic closure or diversion. The entire process is cumbersome and carries significant safety risks.

[0003] The disadvantages of existing technologies are as follows: ① Installing the formwork support for the cap beam on existing highways occupies existing driving lanes, continuously affecting vehicle traffic, frequently causing traffic jams, and affecting residents' travel; ② Many existing vehicles are diverted to other roads, resulting in increased traffic flow on other roads and increased traffic pressure; ③ The amount of materials used for erecting the support is large; ④ Erecting the support generally takes 2 to 3 working days and requires a large number of workers and machinery, which is time-consuming and labor-intensive, increasing the construction period and project cost; ⑤ Carrying out concrete pouring, hoisting, and other operations on existing highways that are already in operation poses significant safety risks.

[0004] Against this backdrop, in order to achieve safe and rapid operation during the installation of the cap beam, the applicant proposed a new solution. Utility Model Content

[0031] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0032] In the description of this utility model, "multiple" means two or more; "greater than," "less than," and "exceeding" are understood to exclude the stated number; "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or their sequential relationship.

[0033] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] In this utility model, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] This utility model provides an integrated construction platform for transporting and lifting cap beam modules, such as... Figures 1 to 8 As shown, the system includes a pair of cooperatively moving transport platforms 40, each with a transport plane. A support frame 50 is mounted on each transport platform 40, and a lifting system 60 is located on top of the support frame 50. The two lifting systems 60 on the pair of transport platforms 40 are used to synchronously lift objects loaded on the pair of transport planes. Each transport platform 40 includes a frame module, and a wheel and axle system, power source, and control system mounted on the frame module.

[0036] In this utility model, a pair of transport platforms 40 can carry large objects together and can move collaboratively. The two platforms work together to achieve the overall transportation of extra-long, extra-wide, and extra-heavy goods, making transportation convenient. Each platform can independently complete starting, driving, and turning operations, making it easy to move and relocate. It has a small turning radius and wide applicability, and can flexibly turn and reverse even in narrow road environments, solving the problem of difficult transportation of large equipment in complex environments. The two lifting systems 60 on the pair of transport platforms 40 can simultaneously lift the objects loaded on them. Especially for large goods, the simultaneous lifting of the two lifting systems ensures the safety of the lifting. Large goods are often enormous in size and weight. If only a single lifting system is used, not only is the load concentrated, but the risk of the goods falling is extremely high in the event of equipment failure. When the two lifting systems operate simultaneously, the weight can be evenly distributed, reducing the load on a single system and ensuring the stability of the lifting. The center of gravity of large goods is often difficult to control precisely. Single lifting can easily cause the goods to sway or tilt due to unbalanced forces, or even cause the goods to collide with surrounding objects or suffer structural damage. When the two lifting systems 60 are operating synchronously, they can maintain the stability of the goods throughout the entire process of lifting, moving and lowering through precise coordination and control, avoiding swaying caused by the shift of the center of gravity, and ensuring that the goods can be accurately moved according to the preset trajectory. In addition, the entire vehicle can be moved after lifting to achieve high-level positioning after lifting.

[0037] Furthermore, in some embodiments of this utility model application, such as Figures 1 to 8 As shown, the support frame 50 consists of a pair of steel frame bodies 51 erected vertically on the transport platform 40, and a load-bearing beam 52 set on the top of the steel frame bodies 51.

[0038] Furthermore, in some embodiments of this utility model application, such as Figure 1 , 2 As shown in Figure 3, the lifting system 60 includes a lifting hydraulic jack 61 and a lifting rope 70 connected to the lifting hydraulic jack 61. The lifting rope 70 hangs down from the lifting hydraulic jack 61.

[0039] The lifting rope 70 is a steel strand with a tensile strength of 1860 MPa. After the lifting rope 70 hangs down from the hydraulic jack, its end is usually equipped with a hook, lifting ring or other suitable connecting device to accurately connect with the lifting point on the large cargo, so as to ensure that the cargo can be firmly fixed during lifting and avoid slippage.

[0040] The lifting hydraulic jack 61, as the power core of the system, can generate powerful thrust or pull through hydraulic transmission to precisely control the raising and lowering of the lifting rope 70, thereby achieving the lifting and lowering of goods. When the two lifting systems 60 operate synchronously, the hydraulic jacks on both sides receive unified control signals. By coordinating the hydraulic flow and pressure, the raising and lowering speed and length of the lifting ropes 70 on both sides are kept completely consistent, thus achieving the smooth lifting and moving of goods.

[0041] Furthermore, in some embodiments of this utility model application, such as Figures 1 to 8 As shown, a distribution beam 53 is provided on the load-bearing beam 52, and the lifting hydraulic jack 61 is mounted on the distribution beam 53. The load-bearing beam 52, as the basic load-bearing component of the entire lifting system 60, needs to bear the entire weight from the distribution beam 53, the lifting hydraulic jack 61, and the cargo, and therefore requires extremely high strength and rigidity. The addition of the distribution beam 53 is equivalent to building a "force transfer station" between the load-bearing beam 52 and the lifting hydraulic jack 61. It can evenly distribute the concentrated load transmitted from the lifting hydraulic jack 61 to multiple stress points on the load-bearing beam 52, preventing deformation or damage to the load-bearing beam 52 due to excessive local stress, and significantly improving the stability and safety of the entire load-bearing structure.

[0042] Furthermore, in some embodiments of this utility model application, such as Figures 1 to 8 As shown, multiple parallel horizontal rails 80 are arranged on the transport platform 40, and the bottom of the steel frame 51 is fixedly connected to the horizontal rails 80; the top surfaces of the multiple horizontal rails 80 form a transport plane. The arrangement of the horizontal rails 80 enhances the overall rigidity of the transport platform 40, and when carrying large goods, it can evenly distribute the load from the large goods onto the transport platform 40. In addition, the horizontal rails 80, as the bottom foundation of the steel frame 51, also enhance the structural strength and stability of the steel frame 51.

[0043] Application examples are as follows:

[0044] A construction method for transporting, lifting, and installing precast cantilever cap beams using an integrated construction platform for transporting and lifting these cap beam modules, such as... Figure 9-13 As shown, it includes the following steps:

[0045] S1. Cast a pair of piers 20 on the central divider 10 of the road, or confirm the position of the precast piers 20 on the central divider 10 of the road.

[0046] S2, precast cantilever cap beam 30, the cantilever cap beam 30 is provided with lifting lugs on both sides of its middle part during prefabrication;

[0047] S3. The cantilever cap beam 30 is transported to the side of the pier 20 along the bridge direction by a pair of transport platforms 40. At this time, the cantilever cap beam 30 is loaded on a pair of transport platforms 40. The pair of transport platforms 40 respectively carry loads on both ends of the cantilever cap beam 30, and the flanges at both ends of the cantilever cap beam 30 fall on the transport platforms 40 respectively.

[0048] S4, a pair of transport platforms 40 transport cantilever cap beam 30 rotated 90° to the side of the transverse bridge pier column 20;

[0049] S5. Two lifting systems 60 on a pair of transport platforms are connected to the lifting lugs embedded in the cantilever cap beam 30 via lifting ropes 70, and the cantilever cap beam 30 is lifted up. The lifting system 60 lifts the cantilever cap beam 30 to a position 20cm above the top of the pier column 20.

[0050] S6. A pair of transport platforms 40 are moved laterally, and the cantilever cap beam 30 is placed horizontally above the pier column 20.

[0051] S7. Using the lifting system 60, the cantilever cap beam 30 is lowered until it reaches the top of the pier column 20, completing the lifting and installation of the cantilever cap beam 30. Specifically, the lifting system 60 controls the cantilever cap beam 30 to slowly fall onto the temporary support at the top of the pier column 20. After precise adjustment of its position, the cantilever cap beam 30 is finally connected to the pier body, thus completing the lifting and installation of the cantilever cap beam 30.

[0052] In the above implementation, the transportation and lifting of the cantilever cap beam 30 are integrated and are accomplished by a pair of transportation platforms and their lifting systems. The cantilever cap beam 30 is transported by carrying both ends of the cantilever cap beam 30 on a pair of transportation platforms 40. After being transported to the site, it is rotated 90° to the side of the pier 20 in the transverse direction of the bridge. Then, the cantilever cap beam 30 is lifted up by the two lifting systems (60) on the pair of transportation platforms 40. Finally, the pair of transportation platforms 40 are moved laterally so that the cantilever cap beam 30 is located directly above the pier 20. The installation work is completed by lowering the cantilever cap beam 30 and connecting the cantilever cap beam 30 and the pier 20. The existing implementation plan is to set up a large number of steel pipe supports on the existing road to form a working platform. Then, steel bars are tied on the supports, formwork is erected, and concrete is poured to construct the cantilever cap beam 30. One method involves erecting a large number of steel pipe supports for the construction of the cantilever cap beam 30. The other method involves using this integrated construction platform for transporting and lifting the cantilever cap beam 30 after it has been prefabricated to complete the transportation, lifting and installation operations. This integrated construction platform for transporting and lifting the cantilever cap beam 30 has advantages such as flexible transport, convenient lifting, high efficiency, short time, low cost, high safety, minimal traffic impact, and stable construction quality.

All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
