Description

Technical Field

[0001] This utility model relates to the field of railway station assembly and construction technology, specifically to a trolley for installing prefabricated components of prefabricated railway stations. Background Technology

[0002] Prefabricated railway stations offer advantages such as rapid construction, small footprint, and minimal impact on the surrounding environment. They also feature energy efficiency, environmental friendliness, and low labor requirements. The application of prefabricated assembly technology not only yields significant technical, economic, and social benefits but also holds considerable promotional value, representing the industrialization and factory-based development of the construction industry and an inevitable trend for the future development of the rail transit sector. However, prefabricated railway stations also face challenges. The prefabricated components are diverse, require high installation precision, and involve complex installation procedures. Furthermore, the installation of these components in underground pits necessitates the use of retaining structures to prevent collapse on either side of the pit. These retaining structures consist of diaphragm walls, multiple steel supports, and concrete supports. Some components require lintels on the side walls to accommodate the steel supports, with these lintels protruding from the side walls. Some components are located below the steel supports, concrete supports, and lintels, making direct hoisting by gantry cranes impossible and significantly impacting the installation process.

[0003] Chinese patent document CN223482663U, published on October 28, 2025, discloses a fully prefabricated assembled station with columns. It includes two bottom trolleys and two top trolleys spaced apart on either side of a central column. Each bottom trolley has a bottom traveling mechanism that can move back and forth on a bottom track on a base plate. Each top trolley has a central traveling mechanism that can move back and forth on a central track on a central plate. The arrangement of top and bottom trolleys, with two of each type spaced apart, results in the entire assembly trolley consisting of four independent parts, making it suitable for prefabricated assembled stations with a single-column, double-span structure. Most of the devices used for assembling the main station structure are located on the bottom trolleys, giving the entire assembly trolley a top-light, bottom-heavy structure. This rational overall arrangement effectively simplifies the support structure of the panels during installation.

[0004] However, the above technical solutions cannot achieve the efficient assembly line operation mode of "storing on the vehicle and retrieving on the spot" for the side walls, which slows down the overall construction pace. Utility Model Content

[0005] To address the technical problems existing in the prior art, this utility model provides a trolley for installing prefabricated components of prefabricated railway stations. It is unaffected by steel supports, concrete supports, and girders, can adapt to the installation of various prefabricated components, has high installation accuracy, facilitates fine-tuning and positioning, and effectively improves the installation efficiency of prefabricated components.

[0006] This utility model is achieved through the following technical solution: This utility model provides a trolley for installing prefabricated components of a prefabricated railway station, including a left-line trolley and a right-line trolley, which are independently arranged on tracks on a base plate or a middle plate. Both the left-line and right-line trolleys include a trolley frame, which is supported on the tracks by a traveling mechanism at its bottom. The trolley frame includes an upper body and legs for supporting the upper body. The upper body includes two main beams arranged along the track direction and two end beams perpendicular to the track direction, and the main beams and end beams are connected by bolts. The trolley frame integrates a side wall mounting device, a side wall storage device, a middle plate mounting device, and an electrical system for providing power. The side wall mounting device is mounted on the main beams, the side wall storage device is mounted on the legs, and the middle plate mounting device is mounted on the end beams. The main beam of the left-line or right-line trolley is equipped with a column adjustment device for adjusting the verticality of the columns.

[0007] The sidewall installation device includes an up-and-down adjusting cylinder for vertically lifting and lowering the sidewall, a front-and-back adjusting cylinder for horizontally moving the sidewall in the direction of the vertical trolley track and moving the sidewall from the sidewall storage platform to the sidewall installation position, and a horizontal adjusting cylinder for horizontally moving the up-and-down adjusting cylinder and the front-and-back adjusting cylinder above the sidewall storage platform, while simultaneously achieving fine-tuning of the sidewall horizontally along the trolley track.

[0008] The middle plate mounting device includes a lifting cylinder for adjusting the middle plate and the top plate up and down, a horizontal moving cylinder one for moving the middle plate and the top plate horizontally in the direction of the vertical trolley track, and a horizontal moving cylinder two for adjusting the rotation angle of the middle plate and the top plate.

[0009] The column adjustment device includes a telescopic mechanism one for adjusting the verticality of the column in the direction of the vertical trolley track, a telescopic mechanism two for adjusting the verticality of the column along the direction of the trolley track, and a clamping mechanism for clamping the column. The clamping mechanism is fixedly mounted on the telescopic mechanism one.

[0010] The sidewall storage device is equipped with a clamping mechanism for clamping the sidewall.

[0011] The sidewall storage device is equipped with a holding cylinder for maintaining the stable movement of the sidewall during installation, and the piston rod head of the holding cylinder is equipped with a vacuum suction cup.

[0012] The head of the up-and-down adjusting cylinder is equipped with a lifting ring for connecting to the top of the side wall.

[0013] The clamping mechanism is a two-part type, including clamp one and clamp two. One end of clamp one is hinged to one end of clamp two, and the other end is integrated with the other end of clamp two through a locking mechanism.

[0014] The outriggers are connected to the lower end of the main beam by bolts.

[0015] The support leg has a box-shaped end face that is wider at the top and narrower at the bottom within the span plane.

[0016] The beneficial effects of this utility model are mainly reflected in the following aspects: 1. This utility model allows the components to run directly on the track of the bottom or middle plate, without being affected by existing steel supports, concrete supports, or waist beams in the foundation pit. It can accurately transport and install components in areas that traditional gantry cranes cannot cover, solving the installation problem of prefabricated components in complex foundation pit environments. It significantly improves the installation efficiency and accuracy of prefabricated components for prefabricated stations and enables a highly efficient assembly line operation mode of "storing on the vehicle and retrieving on-site" for side walls, thereby improving the overall construction pace.

[0017] 2. This utility model adopts a design with independent arrangement of left and right track trolleys, which can flexibly adapt to station structures with different widths and layouts.

[0018] 3. This utility model achieves precise micro-adjustment of components in multiple degrees of freedom by designing dedicated adjustment mechanisms for different components, such as the three-way hydraulic cylinders for the side wall mounting device (up / down, front / back, and horizontal) and the lifting and horizontal hydraulic cylinders for the middle plate mounting device. The two sets of horizontal moving hydraulic cylinders of the middle plate mounting device work together to not only translate but also adjust the angle of the components, greatly improving installation accuracy and efficiency.

[0019] 4. In this utility model, the side wall storage device is specially equipped with a clamping mechanism and a holding cylinder with a vacuum suction cup. During the movement of the trolley and the installation of components, it can firmly clamp and stably support the side wall, effectively preventing the slippage of heavy precast components and ensuring construction safety.

[0020] 5. This utility model's column adjustment device, through a two-way telescopic mechanism combined with a two-lobed clamping mechanism, can perform precise bidirectional verticality adjustment and reliable clamping of the central column, ensuring high-precision installation of key vertical load-bearing components in the station structure, which is difficult to achieve with traditional construction methods.

[0021] 6. In this utility model, the outriggers adopt a box-shaped cross-section that is wider at the top and narrower at the bottom, which ensures the overall stability during operation.

[0022] 7. This utility model realizes multiple uses in one machine, and can independently complete the entire process of precise positioning, fine adjustment and assembly of various prefabricated components such as side walls, middle slabs and top slabs. It significantly reduces the types and quantities of equipment required on the construction site, simplifies the construction process, and significantly enhances the safety of the construction process.
