Description

Technical Field

[0001] This utility model relates to the field of lifting vehicle technology, and in particular to a lifting vehicle for group vertical molds. Background Technology

[0002] Precast concrete components have become an indispensable part of modern architecture due to their reliable quality, high construction efficiency, and environmental friendliness. However, traditional flat-mold production methods, limited by horizontal casting, suffer from low production efficiency, large formwork requirements, and excessive space occupation, and struggle to flexibly meet the market's diverse and personalized component demands. Against this backdrop, vertical formwork technology for precast concrete has emerged as a leading solution, offering innovative vertical casting methods. It effectively improves production efficiency, reduces formwork usage, saves space, and allows for flexible mold adjustments to adapt to different component production needs, making it a key force driving the upgrading of precast component production.

[0003] To address the shortcomings of flat mold production, existing technologies have introduced a group vertical mold production method to manufacture precast components. This method has improved production efficiency to some extent, but it still has certain limitations in terms of operational efficiency.

[0004] Specifically, the existing modular molds are quite tall, causing numerous inconveniences to production operations. After each production task is completed, a series of tedious operations are required, including cleaning the molds, spraying release agent, and installing the upper, lower, and left / right molds. These operations not only consume a lot of time but also result in low overall operational efficiency.

[0005] Patent document CN212954215U discloses a high-altitude rail lift vehicle for in-plant rail-driven movement, including a slide rail and an electric telescopic rod. A first slider is installed above the slide rail, and a support plate is installed above the first slider. A fixing block is installed in the middle of the support plate, and an electric telescopic rod is installed above the fixing block. Sliding grooves are installed on both sides of the fixing block, and lower sliders are installed inside the sliding grooves. A second connecting rod is installed above the lower slider, and a first connecting rod is installed on one side of the second connecting rod. This utility model features a first slider, which facilitates the sliding of the support plate on its surface, allowing for multi-angle movement by the user. The two first sliders ensure movement speed and stability, preventing tilting. The casters allow the lift vehicle to be moved at any time according to the user's wishes, improving its flexibility and speed, and effectively saving the user's working time.

[0006] As in the prior art of the aforementioned patent, the device achieves the lifting and lowering of the carrying platform and the movement of the vehicle body through a shear-type lifting frame and a moving device. The shear-type lifting frame uses a specific mechanical structure to extend and retract to drive the platform's lifting and lowering, while the moving device allows the vehicle body to move flexibly horizontally. However, in practical applications, raising the carrying platform to a high position poses a risk of falls for workers above. Although safety railings can reduce this hazard, in group formwork projects, the mobile lifting vehicle is often located below the pouring platform, stored when not in use and moved out when needed. Since the space there is limited, the lifting vehicle is generally not equipped with a safety railing in actual production. This significantly increases the risk to workers, as working at heights without effective protection easily leads to falls.

[0007] It is evident that existing mobile lifting vehicle technology is facing a dilemma in the application of group vertical formwork engineering, and there is an urgent need for a group vertical formwork lifting vehicle to optimize production and ensure safety. Utility Model Content
