Description

Technical Field

[0001] The utility model relates to the technical field of masonry trolleys, in particular to a steel template lining trolley. Background Art

[0002] In the field of construction engineering, especially during concrete construction, the use of formwork is crucial. With the continuous development of the construction industry, the requirements for the quality and efficiency of concrete construction are increasing. This has led to the development of a steel formwork lining trolley, primarily used in concrete lining construction for tunnels, culverts, and other structures. It provides a mold space for concrete pouring, ensuring that the shape and size of the concrete structure meet the design requirements. The emergence of steel formwork lining trolleys is designed to meet the needs of large-scale, high-quality concrete construction, improve construction efficiency, ensure construction quality, and reduce construction costs. They play a vital role in various complex construction environments.

[0003] In concrete construction, in terms of formwork support, in addition to bolt connections, there are also some methods such as scaffolding for support. The scaffolding forms a stable support structure through the construction of rods, providing support for the formwork and ensuring the stability of the formwork during the concrete pouring process.

[0004] In existing concrete construction formwork connection technology, multiple formworks are usually connected together using bolts, which has obvious disadvantages. Manual disassembly and assembly of formwork is not only cumbersome but also time-consuming. In actual construction, construction workers need to tighten or loosen bolts one by one, a process that consumes a lot of manpower and time. Especially in large-scale concrete construction projects, where there are a large number of formworks, frequent disassembly and assembly of formworks seriously affects the construction progress. Moreover, the uncertainty of manual operation can lead to inconsistent bolt tightening, affecting the stability of the formwork connection and posing a potential threat to the quality of concrete pouring. Therefore, a steel formwork lining trolley is proposed to solve the above problems. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a steel formwork lining trolley, including a door frame 2, the door frame 2 is made of high-strength steel, has good rigidity and bearing capacity, and can withstand various loads during the construction process, a moving component is provided at the bottom of the door frame 2, the moving component acts to move the device, a supporting component is provided at the top of the door frame 2, the supporting component acts to support the device, and a processing component is provided at the top of the door frame 2, the processing component acts to facilitate construction;

[0030] The processing assembly includes a portal crossbeam 19. As an important connecting component, the portal crossbeam 19 adopts a thick steel beam structure. The bottom is fixedly connected to the top of the portal frame 2 by a strong welding method, which can effectively transfer and disperse the load. The bottom of the portal crossbeam 19 is fixedly connected to the top of the portal frame 2. The top of the portal crossbeam 19 is fixedly connected to the upper longitudinal beam 20. The upper longitudinal beam 20 is also made of high-strength steel and has good bending and torsion resistance. It provides a stable foundation for the entire processing assembly. The top of the upper longitudinal beam 20 is fixedly connected to the small column 17, and the top of the small column 17 is provided with a top flat mold. 3. The outer wall of the door frame 2 is rotatably connected to the top demoulding cylinder 8, and the output end of the top demoulding cylinder 8 is fixedly connected to the outer wall of the top flat mold 3. The bottom of the upper longitudinal beam 20 is fixedly connected to the cylinder support column 21, and the bottom of the cylinder support column 21 is fixedly connected to the bottom jack 9. The outer wall of the cylinder support column 21 is provided with a square column demoulding cylinder 5, and the output end of the square column demoulding cylinder 5 is fixedly connected to the square column formwork 4. The square column formwork 4 is spliced ​​by special steel formwork, has good dimensional accuracy and surface flatness, and can meet the requirements of square column concrete pouring. The top of the square column demoulding cylinder 5 is provided with a transverse telescopic sleeve 6.

[0031] Specifically, during the concrete pouring process, after the concrete has fully solidified, the top demoulding cylinder 8 is first retracted, and its pulling force or thrust is used to drive the top flat mold 3 to perform a precise flipping action. The top flat mold 3 has hinged ears on both sides, which can be flipped up and down. Then the square column demoulding cylinder 5 is retracted to make it work and drive the square column formwork 4 to perform the demoulding operation smoothly. At the same time, the transverse telescopic sleeve 6 plays a guiding role in the expansion and contraction of the square column formwork 4. After that, the lifting cylinder 7 is retracted, and the guide column 18 is driven by the lifting cylinder 7 to return to its original position smoothly, thereby realizing the overall demoulding process. At this time, the equipment state is adjusted so that the walking wheel 1 contacts the ground, and the moving conditions are met. It can be easily moved to the next workstation for construction, effectively improving construction efficiency and continuity. The overall hydraulic expansion and contraction demoulding has a high degree of automation, which can save a lot of manpower and reduce working hours.

[0032] Reference Figure 2 The support assembly includes a lower longitudinal beam 14 and a portal column 15. The top of the portal column 15 is fixedly connected to the bottom of the portal frame 2, and the top of the lower longitudinal beam 14 is fixedly connected to the top of the portal column 15.

[0033] Specifically, the lower longitudinal beams 14 and portal columns 15 support the device, effectively distributing the load from above and evenly transferring it to the ground or other supporting foundation. The portal columns 15 provide vertical support and work together with the lower longitudinal beams 14 to form a stable frame structure. This structure can withstand various external forces generated during the concrete pouring process, such as vibration and impact, ensuring that the device does not shake or tilt during operation, ensuring construction safety and accuracy.

[0034] Reference Figure 1 and Figure 2 The moving component includes a travel wheel 1, the top of which is fixedly connected to the bottom of the lower longitudinal beam 14. The outer wall of the travel wheel 1 is provided with an active travel 10, the outer wall of the active travel 10 is provided with a motor reducer device 12, the outer wall of the travel wheel 1 is provided with a driven travel 11, the outer wall of the driven travel 11 is provided with a steering cylinder 13, the outer wall of the gantry column 15 is fixedly connected with a cylinder seat 16, the cylinder seat 16 is provided in the middle of the gantry column 15, the outer wall of the cylinder seat 16 is fixedly connected with a lifting cylinder 7, the output end of the lifting cylinder 7 is fixedly connected with a guide column 18, the guide column 18 plays a guiding role in the lifting process of the trolley, ensuring that the trolley can rise and fall smoothly, while bearing a certain lateral force and bending moment. The guide column 18 and the lower longitudinal beam 14 are usually connected by sliding bearings or linear guides to reduce friction resistance and improve the flexibility and accuracy of lifting.

[0035] Specifically, when pouring concrete in the work area, the motor-reducer assembly 12 is first activated. Its powerful power drives the active travel 10 to move smoothly. Simultaneously, the steering cylinder 13 operates, precisely steering the driven travel 11. The two work together to ensure that the travel wheels 1 accurately reach the designated position. Subsequently, the lifting cylinder 7 is activated, driving the guide post 18 to slide smoothly within the lower longitudinal beam 14 until it contacts the ground. This firmly supports the entire assembly, providing a stable support environment for subsequent pouring work and ensuring a safe and smooth construction process. When the assembly needs to be moved, the tires are lowered, allowing the assembly to be easily moved around the construction site or between different workstations thanks to the rolling properties of the travel wheels 1. The travel wheels 1 are adaptable to a variety of ground conditions, ensuring smooth operation on both smooth concrete roads and more rugged temporary construction site roads. During processing, the travel wheels 1 are raised, supported by other supporting structures, significantly improving the assembly's stability during operation. When the travel wheels 1 are raised, the device's center of gravity is lowered, and its contact area with the ground is larger and more stable. This allows it to better withstand various external forces generated during concrete pouring and formwork installation, such as vibration, impact, and uneven load distribution. This stability is crucial to ensuring construction quality, effectively preventing problems such as uneven concrete pouring and formwork deformation caused by device sway or displacement, ensuring that construction accuracy and project quality meet design requirements.

[0036] Working principle: When pouring the working area, the active walking 10 is driven to move by the motor reducer device 12, and the driven walking 11 is driven to turn by the steering cylinder 13, thereby driving the walking wheel 1 to accurately reach the specified position, and then the lifting cylinder 7 is started, and the guide column 18 is driven by the lifting cylinder 7 to slide inside the lower longitudinal beam 14 and contact the ground to support the device and keep it stable, so as to pour. After the concrete solidifies, the top demoulding cylinder 8 is retracted, and the top flat mold 3 is driven to flip through the top demoulding cylinder 8, and then the square column demoulding cylinder 5 is retracted, and the square column formwork 4 is driven to demould through the square column demoulding cylinder 5, and then the lifting cylinder 7 is retracted, and the guide column 18 is driven back to its original position through the lifting cylinder 7, so that the whole is demoulded, and the walking wheel 1 is contacted with the ground and moved to the next workstation for construction.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
