Description

Technical Field

[0001] This application relates to the field of elevated platform construction technology, and in particular to an elevated platform trolley unit. Background Technology

[0002] Currently, elevated platforms are commonly used in the structure of railway platforms, such as those for high-speed rail. Due to the structural characteristics of elevated platforms, an elevated passageway is usually provided at the bottom of the platform. This elevated passageway is characterized by its narrow and elongated shape and low height.

[0003] Currently, research on the construction of elevated platforms mainly focuses on using prefabricated steel frame structures or prefabricated frames with precast slabs. For cast-in-place concrete construction, the traditional method of using full-span scaffolding with wooden formwork is still employed, which has many limitations, such as limited operating space leading to difficulties in manual construction, material transportation, and quality control.

[0004] Therefore, there is a need to provide a highly automated trolley unit to reduce the difficulty of manual construction, the difficulty of material transportation, and the difficulty of construction quality control. Utility Model Content

[0005] Therefore, it is necessary to provide an overhead platform trolley unit, the specific technical solution of which is as follows.

[0006] An elevated platform trolley unit includes:

[0007] Trolley support;

[0008] The side wall formwork mechanism includes a side formwork and a shrinkage mechanism. The shrinkage mechanism is connected between the trolley support and the side formwork and is used to drive the side formwork to shrink and expand.

[0009] The top template mechanism includes a top mold, an inside corner template, a lifting mechanism, and a first hydraulic cylinder; the inside corner template is hinged to the edge of the top mold; the lifting mechanism is connected between the top mold and the trolley support and is used to drive the top mold to rise and fall; one end of the first hydraulic cylinder is hinged to the inside corner template, and the other end is hinged to the top mold.

[0010] Furthermore, the retraction mechanism includes multiple connecting rods and a second hydraulic cylinder; one end of each connecting rod is hinged to the trolley support, and the other end is hinged to the side template; multiple connecting rods are arranged along the vertical direction of the elevated platform, and the multiple connecting rods are parallel to each other; one end of the second hydraulic cylinder is hinged to the trolley support, and the other end is hinged to the side template, the second hydraulic cylinder is arranged at an angle and the hinge point between the second hydraulic cylinder and the trolley support is higher than the hinge point between the second hydraulic cylinder and the side template.

[0012] Furthermore, the inner side of the side template is provided with a connecting plate, and the connecting plate is provided with a clamping bolt. When the bevel of the inside corner template abuts against the flat opening of the side template, the clamping bolt abuts against the bevel of the inside corner template.

[0013] Furthermore, the platform support is equipped with a walking system at its bottom, which works in conjunction with a track, which is set on a concrete raft slab.

[0014] Furthermore, the platform support has a portal-shaped structure.

[0033] Example

[0034] This utility model provides an overhead platform trolley unit, referring to... Figure 1 As shown, it includes a trolley support 1, a side wall formwork mechanism 2, and a top formwork mechanism 3.

[0035] Specifically, the side wall formwork mechanism 2 includes a side formwork 21 and a retraction mechanism. The side formwork 21 is used to support the inner side wall 6 of the elevated passage. The retraction mechanism is connected between the trolley support 1 and the side formwork 21, and is used to drive the side formwork 21 to retract and extend.

[0036] Specifically, the top template mechanism 3 includes a top mold 31, a corner template 32, a lift 33, and a first hydraulic cylinder 34. The top mold 31 supports the top of the overhead passage, while the corner template supports the corner between the inner wall 6 and the top of the overhead passage. The corner template 32 is hinged to the edge of the top mold 31. The lift 33 connects the top mold 31 to the trolley support 1, driving the top mold 31 to rise and fall, thus enabling the top mold 31 to be erected and retracted. One end of the first hydraulic cylinder 34 is hinged to the corner template, and the other end is hinged to the top mold 31. The extension and retraction of the first hydraulic cylinder 34 causes the corner template 32 to rotate, thus enabling the corner template 32 to be erected and retracted.

[0037] The overhead platform trolley unit provided in this embodiment can adapt to narrow overhead passages and automatically perform formwork support and demolding operations, which greatly reduces the amount of manual work and the difficulty of the operation. It eliminates the need for manual transfer of full-span scaffolding and formwork structures, reduces the difficulty of material transfer, and reduces human error by reducing the amount of manual work, thereby reducing the difficulty of controlling construction quality and improving construction efficiency.

[0038] Specifically, the shrinkage mechanism includes multiple connecting rods 23 and a second hydraulic cylinder 22. One end of each connecting rod 23 is hinged to the trolley support 1, and the other end is hinged to the side template 21. The multiple connecting rods 23 are arranged vertically along the elevated platform, and are parallel to each other in an arc. During formwork erection and demolding, the multiple connecting rods 23 remain parallel, ensuring that the side template 21 remains parallel to the side of the trolley support 1. The connecting rods 23 do not need to be disassembled before or after demolding and formwork erection, reducing the amount of work involved and improving construction efficiency. One end of the second hydraulic cylinder 22 is hinged to the trolley support 1, and the other end is hinged to the side template 21. The second hydraulic cylinder 22 is arranged at an angle, with its hinge point to the trolley support 1 higher than its hinge point to the side template 21. The first hydraulic cylinder 34 is tilted so that the side template 21 moves obliquely upward toward the trolley support 1 during demolding. This allows the side template 21 to separate from the bottom and sides and reduces the need for demolding space.

[0039] Specifically, during formwork erection, the side of the internal corner template 32 away from the top mold 31 abuts against the top of the side template 21; the side of the internal corner template 32 away from the top mold 31 is a bevel 35; and the top of the side template 21 is a flat opening 26. Since the connecting rods 23 remain parallel during demolding of the side template 21, the movement trajectory of the side template 21 is an upward oblique movement towards the trolley support 1. By setting the side of the internal corner template 32 away from the external corner template as a bevel 35, interference with the demolding of the side template 21 can be avoided, ensuring smooth movement of the side template 21.

[0040] Specifically, the inner side of the side template 21 is provided with a connecting plate 24, and the connecting plate 24 is provided with a clamping bolt 25. When the bevel 35 of the inside corner template 32 abuts against the flat opening 26 of the side template 21, the clamping bolt 25 abuts against the bevel 35 of the inside corner template 32. Since the bevel 35 of the inside corner template 32 is relatively weak, the clamping bolt 25 supports the bevel 35 part, which improves the stability and reliability between the inside corner template 32 and the side template 21.

[0041] Specifically, the platform support is equipped with a walking system 4 at its bottom, which works in conjunction with a track 5, which is set on a concrete raft slab. The walking system 4 drives the trolley support 1 to move, thereby allowing the exterior wall trolley to be moved to different construction sections, improving automation. In this embodiment, the walking system 4 can be a chain-type, roller-type, or other form of walking structure.

[0042] Specifically, the platform support structure is a portal frame structure, facilitating personnel movement and operations.

[0043] Specifically, the trolley support 1 is provided with side wall template mechanisms 2 on both sides, which support the inner side walls 6 on both sides of the overhead passage.

[0044] Demolding process: First, the second hydraulic cylinder 22 retracts, and the connecting rods 23 keep them parallel, causing the side template 21 to move obliquely upward for demolding. Then, the second hydraulic cylinder 22 retracts, causing the internal corner template 32 to flip and demold. Finally, the elevator 33 moves the top template 31 downward, thereby moving the internal corner template 32 downward, providing space for the trolley unit to move horizontally to the next construction segment and avoiding interference.

[0045] Once demolding is complete, the external wall trolley is moved along the track 5 by the walking system 4, thus moving to the next construction segment.

[0046] The formwork process is the reverse of the demolding process described above, and will not be elaborated upon in this embodiment.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
