[0035] Workflow:

[0036] Taking the fork attachment as an example, when the explosion-proof diesel crawler multifunctional scraper enters a narrow lane, the frame assembly 1 rotates around the first rotary reducer 2.2 to a suitable position, and then the mechanical arm assembly 3 rotates to a suitable position with the second rotary reducer 3.1, and the lifting cylinder 3.3 swings up and down to adjust the inclination of the mechanical arm assembly. The secondary arm 3.6 and the tertiary arm 3.8 adjust the length of the mechanical arm with the extension and contraction of the cylinder. The first swing cylinder 3.9 and the second swing cylinder 3.11 are combined, so that the fork has a horizontal and vertical rotation space of ±90°, which can smoothly shovel and load materials on the ground, and can also unload from the rear or side of the transport vehicle. When replacing other attachments, various auxiliary operations can also be completed at a long distance and multiple angles.

[0037] Compared with common auxiliary vehicles such as shovel loaders and tunnel repair machines, the explosion-proof diesel engine crawler multifunctional shovel loader of the disclosed embodiment has smaller dimensions and is suitable for narrow tunnels. It is equipped with a variety of working accessories such as a fork 9, a bucket 10, a digging bucket 11, a breaker hammer 12, and a pipe grabbing manipulator 13, which can be quickly replaced according to the actual working conditions of the tunnel, reducing the cost of purchasing a variety of auxiliary equipment and the congestion during the deployment and withdrawal of a variety of auxiliary equipment, thereby achieving the goal of reducing machines and increasing efficiency.

[0038] The explosion-proof diesel tracked multifunctional scraper of the disclosed embodiment is driven by a turbocharged explosion-proof diesel engine, which reduces the space occupied by the diesel engine, improves the combustion efficiency and the cleanliness of exhaust emissions, and has strong power.

[0039] The disclosed embodiment adopts a double telescopic cylinder with a three-stage telescopic arm structure, which is suitable for long-distance auxiliary operations; two large and small rotary reducers are provided at the bottom of the vehicle body and the bottom of the mechanical arm, so the vehicle body and the mechanical arm can rotate greatly, which significantly improves the operating range of the working accessories of the equipment; the three-stage telescopic arm is equipped with a swing cylinder with a lateral and longitudinal rotation of ±90°, which improves the operational flexibility of the working accessories, facilitates the adjustment of the cutting-in angle of the accessories, and completes auxiliary operations such as fork loading, digging, snatching, and lifting more smoothly and conveniently.
