Embodiment 1

[0020] See Figure 1-4 In the embodiment of the present invention, a shield is a negative ring tube transport fixture, including an apparatus body; the apparatus body includes a carrier plate 1, and the carrier plate 1 is fixedly connected to a circumferentially distributed installation ear plate 12, bearer The plate 1 is fixed by mounting the ear plate 12 and the bolt and the outer trailer, and the carrier plate 1 is fixed vertically connected to the end plate 11, the end plate 11 is a vehicle that provides a multi-layer protection behind the cab and the trailer.

[0021] The carrier plate 1 is provided with a plurality of sets of lower abutting blocks 2, and the lower abutting block 2 is a rectangular block for longitudinal direction, and carries a vertically placed multi-set negative ring tube sheet, negative ring tube The straight stack is more compact, improves the single carrier of the carrier plate 1; the lower abutting block 2 abuts against the lower portion of the vertical...

Embodiment 2

[0025] The difference from the first embodiment is that in order to avoid a rigid collision between the negative ring tube sheet; the lower abutting block 2 is provided with an outer wall abutment plate 13, the outer wall abutting plate 13 and the negative ring tube sheet The outer wall abuts, the outer wall abutting plate 13 indicates that there is a rubber pad, providing a certain lateral buffer while avoiding the adjacent negative ring tube sheets, while the negative ring tube is lateral clamping, performing a fixture Hold, further increase the stability of the negative ring tube sheet.

[0026] The outer wall abutting plate 13 is fixedly coupled with a moving frame 14, and the moving frame 14 penetrates through the fixing frame 15 and is slidable with the fixed frame 15, and the fixing frame 15 is fixed to the arc-shaped abutting plate 6; the mobile frame 14 runs through The screw 16, the screw 16 is threaded with the moving frame 14; the inner end of the screw 16 is rotated b...

Abstract

The invention discloses a negative ring segment transportation and fixing device for shield tunneling, which includes a device body; A group of arc-shaped abutment plates arranged symmetrically. The present invention is provided with a partial abutment block, a sliding block, a positioning bolt, a positioning hole, and an arc-shaped abutment plate to carry out lateral abutment and limit on the negative ring segment, and perform lateral stacking and limit on the negative ring segment, thereby improving the unit capacity. Secondary carrying capacity; through the installation of moving blocks, two-way screw rods, first adjustment wheels, and limit plates, it is suitable for the longitudinal clamping of negative ring segments of different specifications, which is convenient for clamping and fixing operations after hoisting; Connecting plate, moving frame, fixed frame, screw rod, second adjusting wheel, the outer wall abutting plate cooperates with the arc abutting plate and the lower abutting block to carry out horizontal clamping and positioning of the negative ring segment, compared with the traditional steel wire Fastened with straps for added stability.

Description

Technical field [0001] The present invention relates to the field of shield transportation equipment, in particular a negative loop tubular transport fixing device for a shield. Background technique [0002] In the transport operation of the negative ring tube, the flat trailer is transported, and the pillow trailer is fixed, the fixing process is fixed, the fixation process is cumbersome, and the negative ring tube itself is large, and the wire or strap is used in flexibility. The fixed belt is prone to shake, which is easy to cause transportation accidents. Inventive content [0003] It is an object of the present invention to provide a shield negative ring tube transport fixture to solve the problems presented in the above background art. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A shield is a negative ring tube transport fixing device, including a device body; the apparatus body includes a carrier plate; ...
