[0030] The following will be described in detail with reference to the accompanying drawings Figures 1-3 The present application will be further described in detail.

[0031] The embodiment of the present application discloses a pipe piece breaking ring reinforcing structure.

The two ends of the transverse pull rod 2 are respectively connected to the two vertical support rods 1, so as to realize the connection between the two vertical support rods 1. The two ends of the vertical support rod 1 can abut on the inner side wall of the pipe piece, so as to support the pipe piece and reduce the risk of breaking of the whole pipe piece.

The lifting plate 31 is arranged above the lifting rod 3, the lifting plate 31 is arranged above the two lifting rods 3, and the two lifting rods 3 support the lifting plate 31. The lifting plate 31 is arranged close to the upper end of the vertical supporting rod 1, and the workers can stand on the lifting plate 31 to crush the pipe piece, which is convenient for the workers to work, and the lifting plate 31 can intercept the falling of the broken stones in the process of crushing the pipe piece, so that the broken stones are collected, and the construction efficiency is improved.

[0034] With reference to Figure 1 and Figure 2 , the horizontal supporting rod 4 is arranged on the side, away from the horizontal pull rod 2, of the vertical supporting rod 1, one end of the horizontal supporting rod 4 is vertically welded on the vertical supporting rod 1, and the other end abuts against the inner side wall of the pipe piece, so that the pipe piece can be further supported. The horizontal supporting rod 4 can be uniformly and spacedly arranged on the length direction of the vertical supporting rod 1, and two horizontal supporting rods 4 are arranged in the embodiment.

[0035] With reference to Figure 1 and Figure 2 , the horizontal pull rod 2 comprises two rotating parts 21, the two rotating parts 21 are arranged on the two vertical supporting rods 1 respectively, and the two rotating parts 21 are rotatably connected to each other at one end and rotatably connected to the two vertical supporting rods 1 at the other end. The two rotating parts 21 can be parallel to or perpendicular to the ground by rotating. When the rotating rod changes from the horizontal state to the vertical state, the two vertical supporting rods 1 are driven to be close to each other, so that the whole support is contracted, and the support is conveniently stored.

[0036] With reference to Figure 1 and Figure 2 , the driving assembly 5 for driving the rotating part 21 to rotate is arranged on the vertical supporting rod 1, the driving assembly 5 comprises a driving block 51 and a connecting rod 52, and the driving block 51 is slidably connected to the vertical supporting rod 1 along the length direction of the vertical supporting rod 1. One end of the connecting rod 52 is rotatably connected to the driving block 51, and the other end is rotatably connected to the rotating part 21. The sliding driving block 51 can drive the rotating part 21 to rotate and adjust the position of the rotating part 21.

[0037] With reference to Figure 2 and Figure 3The driving block 51 is provided with a locking assembly 6, the locking assembly 6 comprises a limiting rod 61, the limiting rod 61 is slidably connected to the driving block 51 in a direction perpendicular to the sliding direction of the driving block 51, a limiting groove 62 is formed in the vertical support rod 1 at a position corresponding to the limiting rod 61, and the sliding limiting rod 61 can make one end of the limiting rod 61 inserted into the limiting groove 62, thereby limiting the driving block 51 and improving the stability of the support during use; when the support needs to be stored, the sliding limiting rod 61 can be made to be separated from the limiting groove 62, thereby facilitating the storage of the support.
