Description

Technical Field

[0001] The utility model relates to the technical field of trolleys, in particular to a multifunctional trolley for laying waterproof boards with the functions of dragging steel bars and pushing up steel bars. Background Art

[0002] Lining trolleys are essential, non-standard products for secondary lining during tunnel construction. Lifting and flipping formwork are also commonly used in hydraulic tunnels. For larger spans, full-circle trolleys are often employed. Side-arch trolleys are the most common, often used in highway and railway tunnels and underground caverns. A trolley typically consists of a formwork assembly, a top formwork frame, a translation mechanism assembly, a gantry assembly, a master-slave travel mechanism, a screw jack, a hydraulic system, and an electrical system.

[0003] In traditional tunnel lining construction, the laying of waterproof panels and the installation of steel bars mostly rely on manual operations, which are inefficient and prone to errors. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art in which the laying of waterproof boards and the installation of steel bars in traditional tunnel lining construction mostly rely on manual operation, which is inefficient and prone to errors. A multifunctional trolley for laying waterproof boards with the functions of dragging steel bars and pushing up steel bars is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A multifunctional trolley for laying waterproof boards with the function of dragging and pushing up steel bars comprises a trolley body, a working platform is provided inside the trolley body, a lining layer and a primary supporting layer are provided on the outside of the trolley body, the lining layer is located inside the primary supporting layer and is arranged in a ring shape on the outside of the trolley body, an inner layer of steel bars is provided on one side of the lining layer, an outer layer of steel bars is provided on one side of the primary supporting layer, a plurality of electric hoists for lifting waterproof boards are provided on the side of the trolley body, a pulling platform is provided on the bottom of one side of the trolley body, guide rollers are provided on the pulling platform, a center column is provided in the middle position of the bottom of the trolley body, and extended columns are provided on both sides of the bottom of the trolley body, and the bottoms of the extended columns and the center column are provided with the same longitudinal connecting beam.

[0007] In a possible design, two driving wheels are provided on one side of the bottom of the trolley body, and a plurality of driven wheels are provided on the bottom of a side of the trolley body away from the driving wheels.

[0008] In a possible design, a spring balancer is provided at the bottom of one side of the trolley body, and a waterproof coil is provided at the middle position of the top of the trolley body.

[0009] In one possible design, a driving chain is provided on the outer wall of the trolley body, a moving track at the bottom of the longitudinal beam of the climbing trolley is provided on the driving chain, a crawling trolley assembly is provided on the moving track at the bottom of the longitudinal beam of the climbing trolley, a through beam is provided inside the trolley body, a waterproof board mounting beam, a steel bar dragging fixture and a longitudinal steel bar placement frame are installed on the through beam, and a chain driving system is provided inside the trolley body.

[0010] In a possible design, a plurality of annular steel bar pushing mechanisms are provided on one side of the trolley body, an electric control box is provided at the middle position of the bottom of the trolley body, and a plurality of extended escalators are provided on one side of the trolley body.

[0011] In a possible design, a ventilation pipe is provided inside the trolley body.

[0012] In this application,

[0013] 1. There are arch rings at the front and rear of the trolley body. The arch rings are located just outside the door frame. Roller chains are installed on the arch rings. The chains are driven by a motor reducer placed above the beam.

[0014] 2. A walking trolley is provided on the ring chain, and the front and rear trolleys are provided with a through beam, on which a waterproof board installation beam and a steel bar positioning fixture are installed.

[0015] 3. A longitudinal steel bar storage rack is provided on the above-mentioned trolley beam.

[0016] 4. During tunnel construction, geotextile is laid first, and then waterproof board. The laying method is as follows: the circular trolley moves to the lower right corner of the figure, removes the waterproof board beam, manually installs the waterproof board on the beam, and then installs the beam on the beam connecting the front and rear trolleys. The circular trolley moves upward to the other side of the tunnel. During the moving process, the waterproof board is manually pulled out and laid while walking.

[0017] 5. After the geotextile and waterproof sheet are laid, start dragging the steel bars:

[0018] The picture shows 8 circumferential steel bars being dragged at a time, with the steel bars clamped with the extension bolts on the steel bar heads through the ring chain and the clamps.

[0019] After the reinforcement is installed, it is towed from the right side of the tunnel to the left side, initially pulling only the outer ring reinforcement of the secondary lining. During this process, seven rows of lifting cylinders mounted on the gantry extend to hold the ring reinforcement in place.

[0020] When the cart dragging the steel bars reaches the left side of the tunnel, it starts to tie the steel bars, and while walking, it takes out the longitudinal steel bars from the steel bar storage rack and ties them together with the circumferential steel bars.

[0021] Beneficial effects:

[0022] 1. Efficient and automated construction: The motor reducer drives the trolley on the roller chain and the ring chain, realizing automated or semi-automated operations during the tunnel lining construction process, including the laying of waterproof sheets and the dragging and positioning of steel bars. This significantly improves construction efficiency and reduces manual labor intensity and time costs.

[0023] 2. Precise positioning and installation: The combination of steel bar positioning fixtures and lifting cylinders can accurately lift the circumferential steel bars to the predetermined position, ensuring the accuracy and consistency of steel bar installation and improving the quality and safety of the tunnel lining structure.

[0024] 3. Flexibility and adaptability: The design allows the installation sequence and position of waterproof panels and steel bars to be adjusted as needed during the construction process. In particular, during the laying of waterproof panels, the flexible combination of the circular trolley and the through beam enables efficient laying of waterproof panels, while facilitating fine adjustments by on-site operators.

[0025] 4. Improve the working environment: The mechanized construction method reduces the time that construction workers are directly exposed to harsh construction environments, such as moisture and dust, which is beneficial to protecting the health of construction workers and also helps to keep the construction site clean and orderly.

[0026] 5. Improve construction quality: The automated rebar dragging and positioning system reduces human error and ensures the accuracy and stability of rebar installation. The continuity of waterproofing sheet laying helps to improve the overall performance of the tunnel waterproofing layer and extend the service life of the tunnel.

[0027] 6. Promote resource conservation and environmental protection: By improving construction efficiency and reducing material waste, this application helps to achieve resource conservation and utilization. At the same time, mechanized construction methods also help reduce construction noise and dust emissions, which is in line with the concept of green construction.

[0028] In summary, this application has significantly improved the efficiency, quality and safety of tunnel lining construction by introducing automated and mechanized construction technology, while improving the construction environment, promoting resource conservation and environmental protection, and has significant beneficial effects.
