[0019] like Figure 5As shown, the present invention relates to a pipeline adjustment device for a tunnel corridor transport and racking machine, comprising a frame 1, wherein the frame 1 comprises an arc-shaped frame consisting of two support frames 1.1 and a connecting frame 1.2, and the two support frames 1.1 are symmetrically arranged. The support frame 1.1 comprises two arc-shaped support rods, each of which is an arc-shaped rod with a square cross-section. A reinforcing rod 1.11 and a lower support beam 1.10 are respectively welded between the two arc-shaped support rods. The lower support beam 1.10 is arranged above the reinforcing rod 1.11, and the reinforcing rod 1.11 and the lower support beam 1.10 are arranged in parallel. The reinforcing rod 1.11 and the lower support beam 1.10 are both straight plates with a square cross-section. A lower flange 1.8 is welded to both ends of each arc-shaped support rod. Eight lower reinforcing ribs are welded between each lower flange 1.8 and the corresponding arc-shaped support rod. Two lower reinforcing ribs are provided on each side of the arc-shaped support rod, and the lower reinforcing ribs are triangular plates.

[0020] The connecting frame 1.2 includes two arc-shaped connecting rods, which are also circular arc-shaped rods with a square cross-section. Two support plates 1.3 and two upper support beams 1.5 are connected between the two arc-shaped connecting rods. The support plates 1.3 are made of I-beams, and the upper support beams 1.5 are straight plates with a square cross-section. The two support plates 1.3 are arranged between the two upper support beams 1.5, and the support plates 1.3 and the upper support beams 1.5 are arranged in parallel. A fixed beam 1.4 is installed between the two support plates 1.3. The fixed beam 1.4 is arranged perpendicular to the support plates 1.3 and is composed of two parallel U-shaped plates. A fixed plate 1.6 is provided at the transverse center axis of each upper support beam 1.5. The support beam 1.5 and the fixed plate 1.6 are an integrated structure, and the length of the fixed plate 1.6 is greater than the width of the upper support beam 1.5. An adjustment slot 1.7 is provided on the fixed plate 1.6. The adjustment slot 1.7 is a rectangular through slot. An upper flange 1.9 is welded at both ends of each arc-shaped connecting rod, eight lower reinforcing ribs are welded between each upper flange 1.9 and the corresponding arc-shaped connecting rod, two lower reinforcing ribs are provided on one side of each arc-shaped connecting rod, and the lower flange 1.8 on the upper side of each arc-shaped support rod is arranged corresponding to the corresponding connecting upper flange 1.9, and any corresponding lower flange 1.8 and upper flange 1.9 are connected by bolts.

[0021] Combine Figure 1 、 Figure 2 and Figure 3As shown, an adjustment device is installed in the middle above the frame 1. The adjustment device includes an adjustment support frame, which includes a crossbeam 10. The crossbeam 10 is made of I-beam steel. An inclined adjustment plate 11 is welded to each section of the crossbeam 10. The crossbeam 10 and the two adjustment plates 11 form a U-shaped frame. The adjustment plates 11 are square folded plates. The outer folds of each adjustment plate 11 are provided with mounting holes 11.1. The mounting holes 11.1 are circular through holes. Each mounting hole 11.1 is installed in a corresponding adjustment hydraulic cylinder 4. The adjustment hydraulic cylinder 4 is correspondingly arranged in a corresponding adjustment slot 1.7. The piston rod of each adjustment hydraulic cylinder 4 is connected to a U-shaped connecting plate 4.1. The two U-shaped connecting plates 4.1 are connected to an adjustment strap 5. The ends of the adjustment strap 5 are fixed to the corresponding U-shaped connecting plate 4.1 via pins. The adjustment strap 5 is made of a long steel belt or iron chain. A base plate 13 is screwed below the crossbeam 10 and positioned between the two U-shaped plates that hold the beam 1.4 in place. Two mounting brackets 14 are screwed to the base plate 13, securing a bidirectional piston hydraulic cylinder 15. These brackets 14 are square plates with a receptacle and an opening that connects to the receptacle. The receptacle 15 is inserted into the receptacle and then secured with screws. Two hinged mounts 16 are mounted on the frame 1. These hinged mounts 16 are conventional. The two piston rods of the bidirectional piston hydraulic cylinder 15 are connected to their corresponding hinged mounts 16 via pins. A slide 17 is welded to the underside of each adjustment plate 11. These slides 17 are square plates with U-shaped slots 17.1 on opposite sides. These slides also have circular through-holes 17.2, which the adjustment hydraulic cylinder 4 is mounted within via ball bearings. The circular through-hole 17.2 effectively ensures that the force applied to the cylinder rod of the adjustment hydraulic cylinder 4 remains axial, preventing radial forces on the piston rod of the adjustment hydraulic cylinder 4, which could damage the cylinder. A guide plate 18 is screwed to the fixing plate 1.6 on either side of each adjustment slot 1.7. Each guide plate 18 is connected to a corresponding U-shaped slot 17.1 on the slide 17, and a backing plate 18.1 is fixedly attached to the underside of each guide plate 18. A hydraulic station 6, which provides hydraulic power to the bidirectional piston hydraulic cylinder 15, is mounted on the frame 1.

[0022] See also Figure 4As shown, the adjustment device in this scheme can also adopt the following scheme: it includes a guide card assembly 52 installed on both sides of each adjustment slot 1.7, and the guide card assembly 52 is an L-shaped plate. A sliding adjustment plate 51 is connected in a sliding fit between the two guide card assemblies 52 on each side of the frame 1, and each sliding adjustment plate 51 is correspondingly arranged above the corresponding adjustment slot 1.7. An adjustment hydraulic cylinder 4 and an adjustment motor 48 are installed on each sliding adjustment plate 51, and an adjustment sling 5 is connected between the two adjustment hydraulic cylinders 4. A gear 49 is connected to the output shaft of each adjustment motor 48, and a rack 50 is connected to the guide card assembly 52 on the corresponding side of each gear 49 by screws, and the gear 49 is meshed with the corresponding rack 50.

[0023] When the device is in use, one adjusting hydraulic cylinder 4 extends and the other adjusting hydraulic cylinder 4 contracts to adjust the rotation of the steel pipe. The two adjusting hydraulic cylinders 4 extend or contract synchronously to adjust the vertical lifting of the steel pipe. The first structure adjusts the horizontal lateral movement of the steel pipe through the two-way piston hydraulic cylinder 15, and the second method adjusts the horizontal lateral movement function of the steel pipe through two adjusting motors 48.
