[0030] Specifically, this device is provided with a hand pressure pump 13, and the hydraulic oil in the oil tank 10 is manually controlled to be pressed into the driving member 3 through the oil pipe. The driving member 3 is a lifting cylinder, which pushes the piston rod of the driving member 3 to move, and the piston rod drives the lifting component 4 to reciprocate in the vertical direction. By arranging a lifting component 1 above the lifting component 4, and the lifting component 1 has two brackets 1.1 adapted to the U-shaped beam, the U-shaped beam can be stably placed in the bracket 1.1, so that the lifting component 4 drives the U-shaped beam to move, and there is no need to build a scaffolding or rely on manpower to lift the U-shaped beam for installation, which reduces the labor intensity and cost of the staff and improves safety. The entire device has a compact layout and occupies a small space. The hand pressure pump 13 is used as the power to control the driving member 3, and the mechanized installation of the U-shaped beam is realized through the lifting component 4. It is suitable for various types of tunnels and does not require power sources such as power supplies and pump stations.

Specifically, the lifting assembly 4 is a scissor-type lifting mechanism, and the end of a scissor arm 4.1 at the top can slide along the first track 2.3 on the upper platform 2 through the first roller 4.4, and the end of the other scissor arm 4.1 is hingedly connected to the first ear seat 2.2. The end of a scissor arm 4.1 at the bottom of the scissor-type lifting mechanism can slide along the second track 7.2 on the base 7 through the second roller 4.5, and the end of the other scissor arm 4.1 is hingedly connected to the third ear seat 7.1, thereby realizing that the driving member 3 can drive the lifting assembly 4 to reciprocate in the vertical direction.

[0036] Further, see Figure 1As shown, the lifting assembly 1 includes three lifting rods 1.2 that form a triangle, and one vertex of the triangle formed by the three lifting rods 1.2 is hinged to the fixed seat 2.1, and the bracket 1.1 is movably arranged at the protruding ends of the two lifting rods 1.2 that are hinged to the fixed seat 2.1.
