Embodiment 1

[0020] see Figure 1-4 , in an embodiment of the present invention, a negative ring segment transportation and fixing device for shield tunneling, including a device body; The plate 1 is connected and fixed with the external trailer by installing lug plates 12 and bolts. The end of the bearing plate 1 is vertically fixedly connected with an end plate 11, and the end plate 11 provides an additional layer of protection for the cab and the vehicle behind the trailer.

[0021] The bearing plate 1 is provided with multiple groups of lower abutting blocks 2, the lower abutting blocks 2 are rectangular blocks arranged vertically, and the bearing plate 1 is loaded with multiple sets of vertically placed negative ring segments, and the negative ring segments are vertically arranged. The vertical stacking is more compact, and the single load capacity of the bearing plate 1 is improved; the lower abutment block 2 abuts against the lower part of the vertically placed negative ring segment...

Embodiment 2

[0025] The difference between this embodiment and Embodiment 1 is that in order to avoid rigid collision between the negative ring segments; an outer wall abutment plate 13 is provided above the lower abutment block 2, and the outer wall abutment plate 13 and the negative ring segment The outer wall is abutted, and the outer wall abutment plate 13 indicates that a rubber pad is bonded to provide a certain horizontal buffer, while avoiding direct contact with adjacent negative ring segments, and at the same time, laterally clamp the negative ring segment to fix the clip. To further improve the stability of the negative ring segment.

[0026] The outer wall abutting plate 13 is fixedly connected with a moving frame 14, the moving frame 14 runs through a fixed frame 15 and is slidably connected with the fixed frame 15, and the fixed frame 15 is fixedly connected with the arc-shaped abutting plate 6; the moving block 14 runs through a Screw mandrel 16, screw mandrel 16 is threaded...

Abstract

The invention discloses a negative ring duct piece transporting and fixing device for a shield. The negative ring duct piece transporting and fixing device comprises a device body, the device body comprises a bearing plate, a plurality of sets of lower abutting blocks are arranged on the bearing plate, and a set of arc-shaped abutting plates are symmetrically arranged above the lower abutting blocks. According to the negative ring duct piece transporting and fixing device for the shield, by arranging the abutting blocks, sliding blocks, positioning bolts, positioning holes and the arc-shaped abutting plates, transverse abutting limiting is conducted on negative ring duct pieces, transverse stacking limiting is conducted on the negative ring duct pieces, and the single-time carrying capacity is improved; by arranging moving blocks, bidirectional lead screws, first adjusting wheels and limiting plates, longitudinal clamping of the negative ring duct pieces of different specifications isadapted, and clamping and fixing operation after hoisting is facilitated; and by arranging outer wall abutting plates, movable frames, fixed frames, lead screws and second adjusting wheels, the outerwall abutting plates are matched with the arc-shaped abutting plates and the lower abutting blocks to transversely clamp and position the negative ring duct pieces, and compared with traditional steelwire and bandage fixing, stability is improved.

Description

technical field [0001] The invention relates to the field of shield tunneling equipment, in particular to a negative ring segment transportation and fixing device for shield tunneling. Background technique [0002] During the transportation of the negative ring segments, flatbed trailers are used for transportation, and sleepers and steel wires or straps are used for fixing on the flatbed trailers. The fixing belt is prone to shaking, which is likely to cause transportation accidents. Contents of the invention [0003] The object of the present invention is to provide a negative ring segment transportation and fixing device for shield tunneling, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A negative ring segment transportation and fixing device for shield tunneling, including a device body; the device body includes a bearin...
