[0026] The bottom of the base a1 and the bottom of the base b3 are located on the same horizontal plane, and the base a1 is connected to the base b3 through a telescopic device, and the telescopic device includes a fixed plate 4 fixedly connected to the top of the base a1 and the top of the base b3, and the two fixed plates 4 are connected through a single hydraulic cylinder a5. When the single hydraulic cylinder b8 supports the U-shaped steel shed for retaining slag, the single hydraulic cylinder a5 can move the base b3 by telescopic means, or when the single hydraulic cylinder c12 supports the top plate in the lane, the single hydraulic cylinder a5 can move the base a1 by telescopic means, so as to facilitate the adjustment of the position of the base a1 or the base b3 according to the needs on site, without the need to carry the single hydraulic cylinder b8, and reduce the work intensity during the installation of the U-shaped steel shed for retaining slag.

[0027] In the present utility model, more specifically, two fixed plates 4 are connected by two limited telescopic rods 6, and the telescopic device includes a fixed plate 4 fixedly connected to the top of the base a1 and the top of the base b3, and the two fixed plates 4 are connected by a single hydraulic cylinder a5, and the two limited telescopic rods 6 are respectively located on both sides of the single hydraulic cylinder a5. Due to the rugged ground underground, the base a1 and the base b3 are often not on the same horizontal plane during the movement, and the base a1 or the base b3 is not on the same horizontal plane, which will generate vertical downward gravity on the single hydraulic cylinder a5, causing it to bend, and the limited telescopic rod 6 can share part of the vertical downward gravity, reduce the vertical pressure on the single hydraulic cylinder a5, and avoid damage to the single hydraulic cylinder a5. It should be noted that the limited telescopic rod 6 is composed of a steel pipe and a metal rod, and the steel pipe is directly slidably sleeved on the outer wall of the metal rod.

[0028] The top of the base a1 is fixedly connected to a fixed base 7, and a single hydraulic cylinder b8 is installed on the top of the fixed base 7.

A limit column 104 is inserted on the C-shaped baffle 103. The function of the fixed base 7 is to fix the single hydraulic cylinder b8 on the top of the base a1. The bottom of the support plate 101 is abutted against the top of the tray a9, the limit snap-in 102 on the support plate 101 is clamped on the outer wall of the U-shaped slag retaining upper steel shed, and the top of the support plate 101 is abutted against the bottom of the upper end plate of the U-shaped slag retaining upper steel shed, so that the position of the support plate 101 rises and drives the U-shaped slag retaining upper steel shed to rise, so that the connecting device can lock and fix the U-shaped slag retaining upper steel shed and the U-shaped slag retaining lower steel shed. The C-shaped baffle 103 wraps the pallet a9 from three directions, and the limiting column 104 limits the side of the C-shaped baffle 103 that does not wrap the pallet a9. In addition, the pallet a9 can also be limited from the bottom, and the support plate 101 limits the pallet a9 from the bottom. The C-shaped baffle 103, the support plate 101 cooperate with the limiting column 104, so that the support device 10 is stably fixed and clamped on the top of the pallet a9, which can improve the connection stability between the single hydraulic cylinder b8 and the U-shaped steel shed of the lower steel shed of the U-shaped slag retaining wall during the process of lifting the U-shaped steel shed of the slag retaining wall, thereby avoiding slippage and causing the U-shaped steel shed of the slag retaining wall to slide down and fall, and injure the worker's palm.

[0029] In the present use model, more specifically, a detachable single hydraulic cylinder c12 is installed on the top of the base b3, a tray b13 is installed on the top of the single hydraulic cylinder c12, the top of the base b3 is connected to a fixed block 11 by fixing bolts, and the single hydraulic cylinder c12 is fixedly installed on the top of the fixed block 11.
