Product Description:

Features:

The engineering machine has a chassis that features four-wheel drive, making it great for climbing steep terrain. Additionally, it comes equipped with four-wheel steering, allowing for a small turning radius. This makes it ideal for use in tunnel construction projects.

The main arm of the equipment is designed with a folding and telescoping structure, which can be easily folded back to the frame during transportation and driving. In addition, this main arm can be equipped with multiple arches to transport unit A, making it adaptable to step construction methods and cross-step operations.

The tray of the main arm has a unique function that allows it to transport multiple arches. The maximum adjustment distance between the arch clamping mechanism and the tray is 2400mm. With a spacing of 800mm, the tray can support up to four arches at a time, and it can automatically adjust the arch spacing to adapt to different sizes. The tray also has multiple degrees of freedom, making it easy to install and adjust the arch.

The auxiliary arm platform has an arch dragging device, which allows the main arm to stand on the step arch while standing on the middle step arch during three-step constructions. This platform assists in erecting arches on both sides during half-section or full-section work. The towing device can tow the arches from any position on the ground to the platform, making it easy to dock and connect the arches.

The linkage mechanism at the end of the main arm, in conjunction with the tray action, can independently install arches on the ground. Additionally, the tray can automatically adjust to the initial set leveling state through sensing devices and self-memory functions, reducing manual adjustment time and difficulty.

For safety, an anti-collision warning system is installed for the boom. This system monitors the coordinates of the boom in real-time and can warn of critical collisions, ensuring safe operation by collaborating with multiple arms safely over a wide range. The equipment is also equipped with an overload warning and protection system that monitors the load distribution at the end of the boom in real-time, providing equipment overload warning reminders to ensure safe operation.

The machine also has an intelligent fault analysis and diagnosis system. It monitors and records the operating status of the equipment using various sensing devices on the device. When the machine malfunctions, it can intelligently diagnose the problem or troubleshoot through remote human-machine interaction mode. Lastly, through advanced electro-hydraulic control technology, the equipment has better maneuverability, smooth movement, and very little end shaking.

Applications:

The tunnel arch erector equipment ensures high levels of security through several features:

• The equipment requires only 2-3 operators and 2-3 construction personnel for product construction, reducing the number of personnel required.
• The equipment's main arm operator is located under the supported surface and uses remote control for lifting the multi arch forming frame. This technique ensures that all construction personnel are not exposed to exposed rock surfaces, improving safety.
• The use of a drag clamping device in the auxiliary arm ensures that the arch frame of Unit B remains under the already supported surface, and the construction personnel can hang it. The operator can remotely operate it to lift and position the arch frame of Unit B.
• Multiple formed arches supporting the arch crown enhance safety during the connection of bolts and welding horizontal bars and mesh as no construction personnel are exposed to exposed rock surfaces, thus improving safety.

The tunnel arch erector equipment achieves high economic efficiency through several features:

• The equipment saves an average of 1-2 hours per work cycle, resulting in a saving of 15-30 days annually.
• Only a minimum of 3 people and no more than 6 people for operation and construction work are required, resulting in significant labor cost savings.
• The equipment only needs to divide the entire arch frame into three sections, saving the number of connecting plates and bolts and thereby reducing material costs.
• It is mobile and versatile, capable of accommodating both palm faces, resulting in further reduction of construction personnel.

The tunnel arch erector equipment is highly adaptable, and can be used for different construction methods:

• The equipment can adapt to the construction requirements of single arch, multiple arch frames, including multiple double arch frames and folding arch frames.
• It can meet the construction requirements of large section tunnels such as high-speed rail double track tunnels and four lane highways, as well as small section tunnels such as flat guide tunnels, transverse tunnels, and inclined shafts.
• The equipment can adapt to the construction requirements of various construction methods such as full section, half section, micro step, and three step tunnels.

The tunnel arch erector equipment has additional features that enhance functionality:

• The equipment's main arm platform can be expanded to meet the installation function of explosive cartridges after drilling holes with the rock drilling rig.
• The equipment's maximum lifting height is 12 meters, and the platform can carry more than one ton. It can be used as an aerial work vehicle for the installation and auxiliary operations of tunnel facilities.
• The hoisting mechanism of the auxiliary arm towing and clamping device could be used as a truck-mounted crane for lifting, installing, and other lifting operations of the inverted arch.
