[0002] At present, after the concrete segments are manufactured, they are usually placed sideways on the segment yard. When transporting, the segments need to be placed on the transport vehicle with one side facing upward. In the prior art, steel wire ropes are usually tied to the segments manually or the segments are clamped by a lifting fixture and then lifted above the vehicle. The direction is then manually adjusted to tilt the segments and then slowly lower them to achieve the effect of the concave side facing upward. Usually, four people are required to operate at the same time.

[0003] In the prior art, the tube segment flipping device for subway tunnel construction with patent number CN210065100U includes a bottom plate, a bracket, a flip assembly, and a support assembly. The bottom plate is horizontally arranged, a bracket is arranged in the middle of the top surface of the bottom plate, a flip driving mechanism is arranged on the bracket, a flip assembly is arranged at the top of the bracket, and the support assembly is arranged on the top surface of the bottom plate. The flip assembly includes a mounting block and a clamping mechanism. The mounting block is a strip block, and the mounting block is horizontally arranged. Both ends of the mounting block are rotatably connected to the top of the bracket. The flip driving mechanism drives the mounting block to flip. Two groups of clamping mechanisms are symmetrically arranged on one side of the mounting block. The two groups of clamping mechanisms are used to clamp the tube segment. The clamping mechanism includes two rotating rods and a plurality of pressure rollers.

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0024] refer to Figure 1-5 A subway pipe segment flipping device includes symmetrically arranged support rods 1, an L-shaped support rod 2 11 is fixedly arranged on the upper surface of the support rod 1, a connecting rod 111 is fixedly connected between the L-shaped support rods 2 11 at the upper ends of the two support rods 1, and a universal wheel 12 is symmetrically fixedly arranged on the lower end surface of the support rod 1. The two support rods 1 and two groups of L-shaped support rods cooperate with the connecting rod 111 to form a movable flipping frame to flip the subway pipe segments 3 at different positions.

[0025] refer to Figure 1 A telescopic cylinder 14 is fixedly arranged on the lower surface of the horizontal rod at the upper end of the L-shaped support rod 11, and a T-shaped support 15 is fixedly arranged on the lower end of the piston rod of the telescopic cylinder 14. A square through groove 13 is opened on the surface of the support rod 1, and the support 15 can slide in the through groove 13 by the drive of the telescopic cylinder 14.

[0026] refer to Figure 2 , 5A connecting plate 24 is provided between the two supports 15, and rotating shafts 241 are symmetrically fixedly provided on the two side surfaces of the connecting plate 24. The rotating shaft 241 penetrates the side surfaces of the support 15 and rotates together. A motor 151 is fixedly provided on the outside of the support 15, and the output shaft of the motor 151 is fixed to one end of the rotating shaft 241. The rotating shaft 241 is driven to rotate by the motor 151, thereby driving the connecting plate 24 to rotate.

[0027] refer to Figure 1-3 A support plate 21 is symmetrically fixed on the upper and lower sides of the connecting plate 24, a groove 211 is provided on the surface of the support plate 21, a bidirectional lead screw 22 is rotatably provided in the groove 211, a motor 212 is fixedly provided on the outer side of the support plate 21, a slider 23 is threadedly provided on the surface of the bidirectional lead screw 22, the slider 23 is slidably provided in the groove 211, the rotation of the bidirectional lead screw 22 is driven by the motor 212, and then the sliders 23 on both sides are driven to slide relative to each other in the groove 211.

[0028] refer to Figure 3 A clamping block 231 is fixedly provided on the upper end surface of the slider 23. The outer side surface and the lower surface of the clamping block 231 are both arc-shaped, which is convenient for contacting the two ends of the subway segment 3 and pressing it downward to stabilize it.

[0029] refer to Figure 5 Support frames 25 are symmetrically fixedly arranged on both sides of the support plate 21, and a placement block 26 is slidably arranged in the support frame 25. A plurality of springs 251 are fixedly connected between the lower end surface of the placement block 26 and the inner bottom surface of the support frame 25.

[0030] The upper end surface of the placement block 26 is provided with a curved surface, which can cooperate with the lower end curved surface of the subway segment 3, so as to facilitate the placement of the subway segment 3.

[0031] Furthermore, the subway segment 3 is suspended by an external lifting device, and then the subway segment 3 is placed on the surfaces of the two placement blocks 26. Then, the two-way lead screw 22 is driven to rotate by starting the motor 212, so that the sliders 23 on both sides drive the clamping block 231 to move relative to each other, and then the clamping block 231 contacts the surface of the subway segment 3 and continues to move, and then the subway segment 3 is pressed. At this time, the placement block 26 descends in the support frame 25, and the spring 251 is compressed until the lower surface of the clamping block 231 contacts the surface of the subway segment 3. At this time, the subway segment 3 is firmly clamped, which can effectively prevent the subway segment 3 from falling or moving during the flipping process.

[0032] Furthermore, after the subway segment 3 is clamped, the motor 151 drives the rotating shaft 241 to rotate, thereby driving the connecting plate 24 to rotate, so that the subway segment 3 is flipped over. At this time, the telescopic cylinder 14 drives the support 15 away from the bottom surface. After the flipping is completed, the support 15 is driven to descend by the telescopic cylinder 14, so that the two ends of the subway segment 3 contact the ground, and then the clamping block 231 releases the subway segment 3, and then the telescopic cylinder 14 drives the support 15 to reset, and then the next subway segment 3 is flipped over.

[0033] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.
