Description

Technical Field

[0001] The utility model relates to the technical field of pipe jacking construction, in particular to a pipe jacking movable bracket. Background Art

[0002] Pipe jacking is a trenchless construction method, a pipeline burial construction technology with no excavation or less excavation. Pipe jacking construction is to use the jacking force generated by the jacking equipment in the working pit to overcome the friction between the pipeline and the surrounding soil, push the pipeline into the soil according to the designed slope, and transport the soil away. After one section of the pipe is pushed into the soil layer, the second section of the pipe is pushed in. The principle is to use the thrust of the main jacking cylinder and the pipeline room, relay room, etc. to push the tool pipe or tunnel boring machine from the working pit through the soil layer to the receiving pit and lift it. The pipeline follows the tool pipe or tunnel boring machine and is buried between the two pits.

[0003] Since the jacking pipe is large, heavy and cylindrical, it is difficult to move it by forklift due to its shape. Transferring it by lifting equipment is inflexible, the transfer distance is limited, and the safety factor is low.

[0004] Therefore, a pipe jacking mobile support is needed to solve the above technical problems. Utility Model Content

[0005] The utility model aims at the technical problems existing in the prior art and provides a pipe jacking movable bracket.

[0006] The utility model solves the above-mentioned technical problem through the following technical solution: a top pipe movable bracket, comprising a rectangular support frame and an arc-shaped support frame, wherein the arc-shaped support frame is welded to the top of the rectangular support frame, the arc-shaped support frame has the same width as the rectangular support frame, and forklift arm slots are fixed on both sides of the bottom of the rectangular support frame.

[0007] Preferably, in the above-mentioned jacking pipe movable bracket, two first reinforcing rods are welded to the front and rear end surfaces of the rectangular support frame, and the first reinforcing rods are in a cross shape and are both located on the end face diagonal lines of the rectangular support frame.

[0008] Preferably, in the above-mentioned jacking pipe movable bracket, two second reinforcing rods are welded to the left and right side surfaces of the rectangular support frame, and the second reinforcing rods are in a cross shape and are both located on the side diagonals of the rectangular support frame.

[0009] Preferably, in the above-mentioned jacking pipe movable bracket, the arc-shaped support frame includes two arc-shaped bars, the two arc-shaped bars are respectively welded to the top of the front and rear end surfaces of the rectangular support frame, and a plurality of mutually parallel cross bars are welded between the two arc-shaped bars.

[0010] Preferably, in the above-mentioned jacking pipe movable bracket, a vertical rod and two oblique rods are welded between the arc-shaped bar and the rectangular support frame, and the two oblique rods are symmetrically arranged on both sides of the vertical rod.

[0011] Preferably, in the above-mentioned pipe jacking movable bracket, the rectangular support frame and the arc-shaped support frame are both made of stainless steel.

[0012] The beneficial effects of the utility model are as follows: by arranging an arc-shaped support frame on the top of the rectangular support frame, it is convenient to stably sleeve the inner top wall of the top pipe on the arc-shaped support frame, and by arranging two forklift arm slots at the bottom of the rectangular support frame, it is convenient to insert the forklift arm and keep the relative position of the forklift arm and the rectangular support frame unchanged, thereby improving the stability during the movement. The utility model lifts the bracket by a forklift, then moves the bracket by the forklift and inserts it into the top pipe, then lifts the bracket by the forklift, then the top inner wall of the top pipe contacts the arc-shaped support frame, and the top pipe is lifted. At this time, the top pipe can be driven to move by the forklift, so that the top pipe can be flexibly transferred. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, a pipe jacking mobile support includes a rectangular support frame 1 and an arc-shaped support frame 2, both of which are made of stainless steel. The arc-shaped support frame 2 is welded to the top of the rectangular support frame 1. Specifically, the arc-shaped support frame 2 includes two arc-shaped bars, which are respectively welded to the top of the front and rear end surfaces of the rectangular support frame 1, and a plurality of parallel cross bars 7 are welded between the two arc-shaped bars. The arc-shaped support frame 2 has the same width and length as the rectangular support frame 1.

[0020] In order to improve the overall structural strength, two first reinforcing rods 3 are welded on the front and rear end surfaces of the rectangular support frame 1. The first reinforcing rods 3 are in a cross shape and are both located on the end face diagonal line of the rectangular support frame 1. Two second reinforcing rods 6 are welded on the left and right sides of the rectangular support frame 1. The second reinforcing rods 6 are in a cross shape and are both located on the side diagonal line of the rectangular support frame 1. A vertical rod 4 and two oblique rods are welded between the arc strip and the rectangular support frame 1. The two oblique rods are symmetrically arranged on both sides of the vertical rod 4. This improves the overall structural strength.

[0021] To facilitate the insertion of the forklift arm, forklift arm slots 5 are fixed on both sides of the bottom of the rectangular support frame 1. Each forklift arm slot 5 has the same distance from the side of the adjacent rectangular support frame 1, so as to keep the center of gravity stable during movement. The forklift arm slot 5 can be fixed to the bottom of the rectangular support frame 1 by bolts or by welding.

[0022] When using the mobile support for pipe jacking to transport pipe jacking, the support is first lifted by a forklift, and the two forklift arms are respectively inserted into the two forklift arm slots 5 to lift the support. Then the support is moved by a forklift and inserted into the pipe jacking 8. During this process, the central axis of the arc-shaped support frame 2 and the central axis of the pipe jacking 8 are kept on the same vertical plane as much as possible to avoid relative sliding with the arc-shaped support frame 2 when the pipe jacking 8 is lifted. Then the support is lifted by a forklift, and then the top inner wall of the pipe jacking 8 contacts the arc-shaped support frame 2, and the pipe jacking 8 is lifted. At this time, the pipe jacking 8 can be moved by the forklift to be transferred to the destination.
