This layout ensures that the core hydraulic and electrical components are effectively protected, and at the same time reserves a safe space for the layout of the lifting arm.

[0018] The base 1 includes a rectangular frame; a pair of longitudinal bars are arranged in the middle of the rectangular frame along the width direction; a window for placing the lifting support 7 is separated by a cross bar at the front side of the gap between the longitudinal bars; strengthening longitudinal bars are also arranged between the two longitudinal bars, the cross bar between the longitudinal bars and the rectangular area surrounded by the rectangular frame; several strengthening cross bars are arranged between the longitudinal bars and the left and right sides of the rectangular frame. This grid-like frame structure significantly improves the bearing capacity and torsional stiffness of the base, providing a solid installation platform for the entire system.

[0019] Positioning plates are installed at the left and right sides of the base 1 corresponding to the positions of the vacuum magnetic starter 3, the motor 6 and the fuel tank 9; positioning holes are opened on the positioning plates; protective plates are installed at the lower bottom of the base 1 corresponding to the left, middle and right positions respectively. These protective plates cover the key areas at the lower part of the base, effectively preventing the scraping or impact of ground obstacles on the bottom components during transportation or work.

[0020] The valve group support 2 includes two relatively placed square frames; a pair of positioning strip plates are respectively arranged on the upper and lower sides between the two square frames; strip holes are opened on the positioning strip plates; the control valve group 4 is installed between the upper and lower pairs of positioning strip plates; the remote control receiver box 5 is installed on the upper positioning strip plate. Placing the remote control receiver box 5 on the positioning strip plate above the valve group support not only facilitates signal reception, but also makes its position relatively independent and easy to maintain.

[0023] Through holes are opened at both shoulders of the fuel tank 9 and at positions opposite to the outer end plates at the top of the vertical frame 12; several through holes for hydraulic pipelines to pass through are also opened on the outer end plates. These reserved through holes ensure that the hydraulic pipelines can be concentrated and orderly led out from the inside of the protective frame and connected to the lifting arm or other actuators, avoiding pipeline clutter and potential wear risks.

[0024] Reference Figure 6 ; The two large round holes at the positions of the two shoulders of the fuel tank are respectively the liquid inlet platform and the air filter interface platform, and a KJ2-19 straight pipe is provided on its side for connecting corresponding hydraulic accessories. Breather ports are provided at positions corresponding to the lower sides of the air filter interface platform and the liquid inlet platform on its front end face to ensure the internal pressure balance of the fuel tank. A strip-shaped return liquid sealing plate is also provided below the liquid inlet platform for guiding the return oil and reducing the generation of bubbles. An outlet liquid platform is also provided on the lower side of its front end face as the suction port of the hydraulic pump.

[0025] One-sided vertical frame 12 includes an edge bracket installed at the end side of the base 1; trapezoidal brackets are also fixed at positions corresponding to the front and rear end sides of the base 1 on the edge bracket; a cross bar is provided between the opposite trapezoidal brackets on the two vertical frames 12; the back of the connecting support 11 leans against the cross bar, and a rib plate is also installed between the top of the cross bar and the connecting support 11. These rib plates further strengthen the connection strength between the connecting support 11 and the vertical frame 12, ensuring that a large connection force can be borne when docking with other equipment.

[0026] Lifting lugs 13 are installed at the positions corresponding to the four corners of the base 1 at the upper top of the vertical frame 12, and a number of reinforcing rib plates are provided on the vertical frame 12 and between the vertical frame 12 and the base 1. These reinforcing rib plates are widely distributed at the corners, joints of the vertical frame and the joint between the vertical frame and the base, greatly enhancing the rigidity and anti-impact deformation ability of the entire protection frame, and effectively ensuring the safety of the internal precision components in the harsh underground mine environment.

[0027] In this embodiment, the motor model used is YBK3-225M-4; the jib 9 can move on the single rail in the mine roadway through the carrier vehicle installed on it. The hydraulic pump installed in the fuel tank sucks oil from the fuel tank 9, and the pressurized hydraulic oil is distributed by the control valve group 4 controlled by the signal of the remote control receiving box 5, and the hydraulic actuators on other equipment act through the pipeline led out from the through hole of the outer end plate of the vertical frame to realize the temporary support function; the oil after work returns to the fuel tank 9 after being filtered and cooled by the return oil pipeline to complete the cycle; the entire system is integrated on the base 1, and is hoisted through the lifting lugs 13 or quickly docked with other single-rail equipment through the docking plate 10 and the connecting support 11, and is carried by the single-rail carrier vehicle and flexibly moved and deployed in the mine roadway.
