Description

Technical Field

[0001] This utility model belongs to the technical field of subway station construction equipment, specifically relating to a fine-tuning device for assembling central columns in prefabricated stations. Background Technology

[0002] The construction technology of prefabricated subway stations can fully realize the factory production of prefabricated components, thereby achieving the goal of rapid on-site assembly. It has many advantages in improving building quality, increasing efficiency, reducing on-site casting work, saving materials, and protecting the environment. When the station has a large span, a central column will be set in the middle of the station. When assembling a prefabricated station with a central column, two separate assembly trolleys on the left and right sides will be used for construction.

[0003] When assembling the central column of the detachable trolley, the central column is assembled by a crane. To ensure that the central column is installed accurately and vertically, it is fine-tuned during crane lifting. Currently, there are two ways to fine-tune the central column: one is to fine-tune it manually, and the other is to install telescopic cylinders in all four directions of the central column to achieve fine-tuning. The former is prone to errors due to manual adjustment, while the latter is prone to over-limitation, making it impossible to fine-tune. Utility Model Content

[0004] This utility model proposes a fine-tuning device for assembling the central column of a prefabricated station, which can effectively ensure the accurate assembly of the central column.

[0005] Therefore, the technical solution adopted by this utility model is as follows: a fine-tuning device for assembling the central column of a prefabricated station, comprising at least two horizontal adjustment components spaced vertically and located on either the left or right side of the central column, and at least two vertical adjustment components spaced vertically and located on either the front or rear side of the central column. All horizontal adjustment components are located on the same side, and all vertical adjustment components are located on the same side. The horizontal adjustment component includes a horizontal fine-tuning cylinder located on the side of the detachable trolley and capable of abutting against the central column. The vertical adjustment component includes a support beam with a detachable structure that extends horizontally and horizontally in the middle of the detachable trolley. The support beam is provided with a vertical fine-tuning cylinder capable of abutting against the central column.

[0006] As a preferred embodiment of the above scheme, the supporting beam includes a short beam and a long beam that are arranged opposite to each other on the left and right sides. The longitudinal fine-tuning cylinder is arranged on the long beam. The short beam and the long beam are both arranged on the separate trolley on the corresponding side through corresponding hinge devices, and the hinge axis of the short beam and the long beam is arranged vertically. The short beam is set as a supporting cylinder, and the end of the long beam opposite to the short beam is provided with a groove for the supporting cylinder to extend into.

[0007] Further preferably, the ends of the lateral and longitudinal fine-tuning cylinders that are in contact with the central column are each provided with an adjusting block that is hinged to the adjusting block. The adjusting block is provided with a support column that is abutted against the central column, and the end of the support column is a ball head. The ends of the lateral and longitudinal fine-tuning cylinders that are away from the central column are also provided with hinges, and the hinge shafts on the lateral and longitudinal fine-tuning cylinders are both vertically arranged.

[0008] Further preferably, the detachable trolley includes two bottom trolleys and two top trolleys spaced apart on both sides of the central column. The bottom trolleys are equipped with a bottom traveling mechanism that can move back and forth on a bottom track on the bottom plate. The top trolleys are equipped with a middle traveling mechanism that can move back and forth on a middle track on the middle plate. The lateral adjustment component is located on either bottom trolley, and the longitudinal adjustment component is located between the two bottom trolleys.

[0009] Further preferably, each bottom trolley has a middle plate trolley at the rear end of its top surface for assisting in the installation of the middle plate. The middle plate trolley is equipped with a middle plate adjustment component for adjusting the position of the middle plate. The middle plate trolley includes a crossbeam that is arranged in sections at the upper end of the bottom trolley. The middle plate adjustment component includes a horizontal movement mechanism, a vertical movement mechanism, and a lifting mechanism.

[0010] Further preferably, the left and right sides of the bottom trolley are provided with lateral adjustment components for positioning the side panels and the central column, and the left and right sides of the two bottom trolleys are provided with side wall tensioning frames for installing the corresponding side panels. The side wall tensioning frame includes a side wall tensioning hoisting mechanism and a side wall tensioning operation platform ladder.

[0011] In a further preferred embodiment, the top plate trolley includes a frame platform and a top plate tensioning frame mounted on the frame platform, wherein the frame platform is segmented.

[0012] Further preferably, the bottom trolley is equipped with a lifting platform at the front end of its top surface for workers to install the top longitudinal beam, and the bottom trolley is equipped with a ladder for workers to move from the bottom trolley to the top plate trolley. Automatic anti-locking devices are provided between the bottom traveling mechanism and the bottom track, and between the middle traveling mechanism and the middle track.

[0013] The beneficial effects of this utility model are as follows: When the central column is lowered by the crane, it tilts towards the corner where the fine-tuning device is arranged. Then, by controlling the extension length of the fine-tuning cylinders arranged at right angles, the accurate assembly of the central column is ensured. During the entire adjustment process, there are only fine-tuning cylinders on both sides, so there will be no over-limitation. At the same time, this fine-tuning device uses fewer hydraulic cylinders, which can effectively reduce costs. The support beam adopts a detachable structure. When the trolley moves, the support beam can be disassembled so that the trolley can pass through the central column, thereby ensuring subsequent adjustments. Attached Figure Description

[0023] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0024] like Figures 2-8As shown, a fine-tuning device for assembling the central column of a prefabricated station mainly consists of at least two lateral adjustment components and at least two longitudinal adjustment components. The lateral adjustment components are located on either the left or right side of the central column, and all lateral adjustment components are arranged vertically at intervals on the same side. The lateral adjustment components include a lateral fine-tuning cylinder 91 that is arranged on the side of the split trolley and can abut against the central column.

[0025] The longitudinal adjustment components are located on either the front or rear side of the central column, and all longitudinal adjustment components are arranged vertically at intervals on the same side. The longitudinal adjustment components include a support beam 110 with a detachable structure that extends laterally and is located in the middle of the split trolley. A longitudinal fine-tuning cylinder 120 that can abut against the central column is provided on the support beam 110.

[0026] Specifically, the support beam 110 includes a short beam 111 and a long beam 112 that are arranged opposite to each other on the left and right sides. A longitudinal fine-tuning cylinder 120 is disposed on the long beam 112. The short beam 111 and the long beam 112 are both disposed on separate trolleys on corresponding sides by corresponding hinge devices, and the hinge axes of the short beam 111 and the long beam 112 are vertically arranged. The short beam 111 is configured as a support cylinder, and a groove for the support cylinder to extend into is provided at the end of the long beam 112 opposite to the short beam 111.

[0027] When the short beam extends into the groove, it ensures that the long beam and the short beam are on the same straight line, thus guaranteeing the longitudinal fine-tuning cylinder's longitudinal setting, i.e., the longitudinal fine-tuning cylinder extends forward and backward. When the detachable trolley moves, the short beam retracts, and then the short beam and the long beam rotate forward or backward around the corresponding hinge axis, ensuring the normal movement of the trolley. The entire assembly and disassembly are convenient; only the short beam and the long beam need to be rotated.

[0028] Both the lateral fine-tuning cylinder 91 and the longitudinal fine-tuning cylinder 120 are provided with hinged adjustment blocks 92 at the ends that are in contact with the central column. The adjustment blocks 92 are provided with support columns for abutting against the central column, and the ends of the support columns are ball heads. The ball head design ensures that the lateral fine-tuning cylinder can accurately abut against the central column.

[0029] Ideally, the ends of the lateral fine-tuning cylinder 91 and the longitudinal fine-tuning cylinder 120 furthest from the central column should also be hinged, and the hinge shafts on the lateral fine-tuning cylinder 91 and the longitudinal fine-tuning cylinder 120 should be vertically set.

[0030] Ideally, the stations applicable to this application are prefabricated assembled stations with a single-column, double-span structure, such as... Figure 1 As shown, the prefabricated assembly station 80 has a rectangular structure formed by a top plate 81, side wall blocks 82 and a bottom plate 83. At the same time, a middle plate 84 is horizontally arranged in the middle of the rectangular structure and a central column 85 is vertically arranged. A central longitudinal beam 86 is arranged in the middle of the middle plate 84, a top longitudinal beam 87 is arranged in the middle of the top plate 81, and a bottom longitudinal beam 88 is arranged in the middle of the bottom plate 83.

[0031] The split-type trolley mainly consists of two bottom trolleys 10 and two top trolleys 20, spaced apart on either side of the central column. To enable movement of the bottom and top trolleys, a bottom traveling mechanism 30 is provided on the bottom trolley 10, which can move back and forth on a bottom track 40 set on the bottom plate. A middle traveling mechanism 50 is provided at the bottom of the top trolley 20, which can move back and forth on a middle track 60 set on the middle plate. To ensure stable support of the bottom and top trolleys during assembly at the station, automatic anti-locking devices are installed between the bottom traveling mechanism and the bottom track, and between the middle traveling mechanism and the middle track. These automatic anti-locking devices are existing technology.

[0032] To facilitate the assembly of the middle plate, a middle plate trolley 70 is provided at the rear end of the top surface of each bottom trolley 10. The middle plate trolley 70 is equipped with a middle plate adjustment assembly for adjusting the position of the middle plate. Specifically, the middle plate trolley 70 includes a segmented crossbeam 71 located at the upper end of the bottom trolley 10. The middle plate adjustment assembly includes a horizontal movement mechanism 72, a vertical movement mechanism 73, and a lifting mechanism 74. The horizontal movement mechanism 72, the vertical movement mechanism 73, and the lifting mechanism 74 use hydraulic cylinders to achieve fine-tuning of the middle plate in the left-right, front-back, and up-down directions, that is, fine-tuning in the horizontal, vertical, and longitudinal directions.

[0033] Lateral adjustment components 11 for positioning the side panels and central columns are provided on both the left and right sides of the bottom trolley 10. The lateral adjustment components are lateral hydraulic cylinders, which are used for fine-tuning the side panels and central columns. At the same time, side wall tensioning frames 12 for installing the corresponding side panels are provided on the left and right sides of the two bottom trolleys 10. The side wall tensioning frames include a side wall tensioning hoisting mechanism for tensioning the hydrocephalus and a side wall tensioning operation platform for workers to operate. The side wall tensioning frames are used to ensure that the front side panel and the rear side panel can be tightly spliced ​​together.

[0034] The roof slab trolley 20 includes a frame platform 21 and a roof slab tensioning frame 22 set on the frame platform 21. The frame platform is segmented, which allows the roof slab trolley to adapt to stations of different widths. The roof slab tensioning frame is used to achieve a tight connection between the previous roof slab and the next roof slab. In order to ensure the tensioning effect, several roof slab tensioning frames are set at intervals on the two roof slab trolleys. The roof slab tensioning frame can provide a roof slab operating platform for workers to operate and a roof slab hoisting mechanism for tensioning the hydrocephalus.

[0035] The bottom trolley 10 includes two rows of support columns 14 spaced apart on the left and right. A main beam 15 is provided between the upper ends of each row of support columns 14, and a connecting beam 16 is provided between the two main beams 15. A longitudinal beam 17 is provided in the middle of each row of support columns 14. The connecting beam 16, the main beam 15, and the longitudinal beam 17 are all segmented, which makes the bottom trolley not only easy to dismantle the equipment later, but also suitable for different station widths.

[0036] To facilitate worker operation, a lifting platform 13 is provided at the front end of the top surface of the bottom trolley 10 for workers to install the top longitudinal beam. A ladder is provided on the bottom trolley 10 for workers to move from the bottom trolley to the top plate trolley. At the same time, there are walkway platforms on the bottom trolley and the top plate trolley, and guardrails are provided on the walkway platforms.

[0037] When assembling prefabricated modular stations, the bottom slab, bottom longitudinal beam, bottom trolley, central column, central longitudinal beam, side wall block, middle slab, top slab trolley, bottom longitudinal beam, and top slab are installed in sequence. The bottom trolley and top slab trolley are installed on their corresponding tracks and then pushed forward during subsequent installation.
