Technical Field

[0001] This utility model relates to the technical field of prefabrication yard construction facilities, and in particular to a rotating platform for crossing the assembly line in a beam yard. Background Technology

[0002] The main facilities of the beam yard are divided into a steel bar plant area, a steel bar binding area, a hydraulic formwork area (pouring area), a steam curing area, a tensioning and grouting area, and a beam storage area. In order to reduce the footprint and realize assembly line operation, after the precast beams are poured, they will be moved at low speed to the steam curing area, tensioning and grouting area, and beam storage area via a mobile platform. After the operation is completed, the mobile platform will be lifted to the return track by a transverse transfer vehicle and returned to the beam production area. The mobile platform track is laid out in the longitudinal production line.

Currently, steel pedestrian walkways are generally used to cross the production lines on the ground between the passages. Each time the walkways are set up, a gantry crane is needed to lift them, which not only reduces construction efficiency but also increases safety risks, resulting in poor safety and low practicality.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Please refer to Figures 1 to 5 Example 1:

[0026] This utility model proposes a rotating platform for spanning an assembly line in a beam yard, comprising: a lower structure and an upper structure. The lower structure includes a platform ring beam 1, a guardrail 2, and a positioning bearing 3. The platform ring beam 1 is a square frame welded from square steel a, and the positioning bearing 3 is pre-embedded in the ground at a corresponding position within the precast beam yard 7. The inner rotating body of the positioning bearing 3 is fixedly connected to the bottom of the platform ring beam 1, and the connection is reinforced by welding with square steel a. The guardrail 2 is fixedly installed on the top of the platform ring beam 1, and a precast component channel 701 is provided on the side of the precast beam yard 7. The upper structure is an upper-bearing structure, and includes an upper ring beam 4, an I-beam 5, and a channel steel plate 6. The upper ring beam 4 is a square frame welded from square steel b, and the I-beam 5 is fixedly connected inside the upper ring beam 4 as a longitudinal beam. The channel steel plate 6 is laid on top of the I-beam 5, and the channel steel plate 6 is fixedly connected to the upper ring beam 4 and the I-beam 5. The upper ring beam 4 is fixedly installed on the top of the platform ring beam 1.

[0027] The dimensions of square steel a are 40mm and 80mm respectively, while the dimensions of square steel b are 30mm and 50mm respectively. In use, square steel a is used to weld the platform ring beam 1. Its size selection can provide a stable lower support foundation for the entire rotating platform, which can meet the structural strength requirements of the platform during rotation and load-bearing process, and ensure the overall stability of the platform. Square steel b is used to make the upper ring beam 4, forming a reasonable size match with square steel a. While ensuring that the upper structure has sufficient load-bearing capacity (to bear the weight of personnel and materials), it can reduce material consumption, realize the lightweight design of the structure, and facilitate the combination and installation with components such as I-beams 5.

[0028] Among them, guardrail 2 is made of 30mm steel pipe and has a height of 1500mm. In use, the 30mm steel pipe diameter can ensure that guardrail 2 itself has sufficient strength and impact resistance, and the 1500mm height meets the standard requirements for safety protection. It can effectively prevent people from falling from the edge of the platform and provide reliable safety protection for passers-by.

[0029] The outer perimeter of guardrail 2 is enclosed with canvas, and safety warning signs are affixed to the outside of the canvas. During use, the canvas enclosure of guardrail 2 can prevent external debris from falling in, and at the same time prevent people from accidentally falling through the gaps in the guardrail while passing through, further improving the safety of the platform. The safety warning signs affixed to the outside of the canvas can remind and warn people passing through, enhance the safety awareness of construction workers, and reduce the occurrence of safety accidents.

[0030] Among them, the I-beam 5 adopts the I10a type, which can provide good bending resistance and load-bearing capacity, meeting the stress requirements of the superstructure of the platform for the longitudinal beams. The I-beams 5 are connected by staggered high square tubes with a spacing of 35cm. The passage steel plate 6 has perforations inside the plate. The I-beams 5 are connected by staggered high square tubes with a spacing of 35cm. This connection method and spacing setting can enhance the overall stability of the superstructure and prevent the I-beams 5 from deforming or displacing under stress. The perforations in the passage steel plate 6 do not affect the load-bearing function of the platform, reduce the weight of the steel plate, and also play a role in anti-slip. At the same time, it facilitates the drainage of rainwater and other liquids, avoiding water accumulation that affects passage safety.

[0031] The platform ring beam 1 is equipped with a positioning pin 101 on its side, and the ground of the precast beam yard 7 is equipped with a positioning pin hole 702 corresponding to the position of the positioning pin 101. In use, the positioning pin 101 on the side of the platform ring beam 1 and the positioning pin hole 702 on the ground of the precast beam yard 7 work together to fix the platform when it does not need to rotate, preventing the platform from rotating unexpectedly due to external forces (such as wind, collision, etc.), and ensuring the stability and safety of personnel passage and material transportation. When the platform needs to be rotated, the pin can be pulled out to realize the platform rotation. The operation is simple and does not affect the construction efficiency.

[0032] It should be noted that in practical applications, the material and size parameters of the rotating platform can be determined according to the specific conditions of the production line, and it is suitable for various production line operations.

[0033] The working principle of this embodiment is as follows: The precast T-beam is poured with concrete in the casting area of ​​the beam yard. After initial setting, the T-beam is moved at low speed to the steam curing area through the precast component channel 701 via a moving platform. The staff stands above the platform and operates the intelligent remote-controlled moving platform, which can observe the movement of the moving platform on the assembly line in real time. When the moving platform approaches the rotating platform, the positioning pin 101 is released to make the rotating platform rotate 90° so that it is parallel to the precast component channel 701. The T-beam with the mold can then enter the steam curing area. After the precast T-beam completes a series of processes such as steam curing, tensioning and grouting, and beam storage, the moving platform performs the return operation. During this period, when the rotating platform is not involved in the construction of the precast T-beam, it can be made perpendicular to the precast component channel 701 for the passage of construction personnel and the transportation of materials. The positioning pin 101 and the positioning pin hole 702 are used to position the usage status.
