Technical Field

[0001] The utility model relates to the technical field of transport racks, in particular to an adjustable transport rack for vertically placing pipe segments. Background Art

[0002] The pipe segment is a ring-shaped prefabricated component made of concrete or steel in underground projects to prevent surrounding rock collapse and isolate groundwater. It is the main assembly component of shield construction and the innermost barrier of the tunnel. It is responsible for resisting soil pressure, groundwater pressure and some special loads. When transporting the pipe segment to the designated location, a transport rack is generally used.

[0003] A common method of transportation is to tie the segments together with thick hemp ropes, fix them on top of the frame, and then use wedge-shaped wood, rubber strips, etc. to fill the gaps to prevent the segments from shifting during transportation, or to support them by welding support frames on the frame to prevent the segments from shifting or falling off.

[0004] However, the pipe segments are supported by welding support frames, so that the position of the support frames is fixed and the size of the pipe segments transported by vehicles is fixed, which is inconvenient to transport pipe segments of different sizes. In view of this, the present application proposes an adjustable pipe segment vertical placement transport frame. Utility Model Content

[0014] Furthermore, an adjusting motor is fixedly installed at the bottom of the middle bottom channel steel, and an output end of the adjusting motor is fixedly connected to the bottom end of the double-headed screw.

[0015] The beneficial effect of adopting the above further solution is: by adjusting the motor to drive the double-headed screw to rotate, the support width of the middle inner support component is adjusted to provide power.

[0016] Furthermore, the tops of the middle fixed channel steel and the fixed channel steels at both ends are fixedly installed with reinforcing side braces, and the tops of the bottom channel steels at both ends are slidably installed with clamping diagonal braces for supporting the clamping support assembly.

[0017] The beneficial effect of adopting the above further solution is: by strengthening the side supports and the clamping diagonal supports, the supporting strength of the middle side support assembly and the clamping support assembly is strengthened, thereby increasing the safety of transportation.

[0018] Furthermore, the reinforced side support includes an extended channel steel fixedly installed on the top of the middle fixed channel steel and the fixed channel steels at both ends, a fixing nut fixedly installed on the side of the extended channel steel away from the middle side support assembly, and a supporting screw threadedly installed inside the fixing nut.

[0020] Furthermore, the clamped diagonal brace includes a third sliding base slidably mounted on the top of the bottom channel steels at both ends and a diagonal brace rod fixedly mounted on the top of the third sliding base. The third sliding base is bolted to the bottom channel steels at both ends by fixing bolts, and one end of the diagonal brace rod is fixedly connected to one side of the second side brace rod.

[0021] The beneficial effect of adopting the above further solution is: the third sliding base is fixed by fixing bolts, so that the diagonal support rod supports the second side support rod, thereby increasing the supporting strength of the clamping support assembly.

[0022] Furthermore, a buffer pad is fixedly installed on the side of the first side support rod, the support plate and the second side support rod that are in contact with the pipe segment.

[0023] The beneficial effect of adopting the above further solution is that the surface of the tube segment is protected by the contact between the buffer pad and the tube segment to prevent the tube segment from being damaged.

[0024] Compared with the prior art, the utility model provides an adjustable segment vertical placement and transportation rack, which has the following beneficial effects:

[0025] The adjustable pipe segment vertical placement transport rack is configured by arranging a middle side support assembly on the top of the middle bottom channel steel, a clamp support assembly on the top of the two end bottom channel steels, and a middle inner support assembly on the top of the middle bottom channel steel. After the pipe segment is placed on the top of the middle bottom channel steel and the two end bottom channel steels, the outer side of the pipe segment is supported by moving the middle side support assembly and the clamp support assembly, and the inner sides of the two pipe segments are supported by the middle inner support assembly, so that the transport rack can support pipe segments of different sizes, which solves the problem that the pipe segment is supported by a welded support frame, so that the position of the support frame is fixed, the size of the pipe segment transported by the vehicle is fixed, and it is inconvenient to transport pipe segments of different sizes.
