Abstract
The utility model provides a maintenance frock of leading rig which characterized in that: include two sets of roll -over stands, the one end of rig assembly before a set of roll -over stand is used for supporting, another organizes the other one end that roll -over stand is used for supporting preceding rig assembly, and each group's roll -over stand is formed by last semi -frame and lower semi -frame combination to it is fixed temporarily with it to be equipped with the cushion, adopts after the above -mentioned structure: shield tunnelling machine is very narrow and small in the job site space of excavating the tunnel, hydraulic pressure appears when leading rig, it is electric, during mechanical breakdown, can't directly maintain on shield tunnelling machine, need dismantle leading rig to get off to overhaul and maintain, the installation station of leading rig be the rock drill down, need utilize a dedicated auxiliary fixtures with the 180 back implementation maintenances of leading rig flip horizontal in tunnel construction, on shield tunnelling machine was installed with it to flip horizontal 180 again after the maintenance was accomplished.
Description
Technical field
This utility model relates to the maintenance frock of a kind of advanced rig.It is mainly used in the job site of shield excavation machine tunneling, when the advanced rig of the assembly of shield excavation machine breaks down, an auxiliary maintaining frock is needed to support this advanced rig, by it inside tunnel on the spot flip horizontal 180 ° keep in repair, after being overturn 180 ° on the spot by this auxiliary mould again after having keeped in repair, advanced rig is installed on shield excavation machine.
Background technology
Shield excavation machine is the narrowest and small in the space, job site of tunneling, when hydraulic pressure occurs in advanced rig, electrically, during mechanical breakdown, directly cannot keep in repair on equipment, need to disassemble advanced rig to overhaul and safeguard, the installation station of advanced rig be rock drill down, need in construction tunnel with manually just implementing maintenance after advanced rig flip horizontal 180 °, in the case of not having frock, the work of this upset can consume relatively more manual labor, loop wheel machine equipment must be had to assist simultaneously, there is also security incidents such as easily colliding with, need a kind of special auxiliary mould inside tunnel by advanced rig supporting, carry out flip horizontal action on the spot, again can be easily by advanced rig flip horizontal after having keeped in repair, it is installed on shield excavation machine.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of special auxiliary mould, will implement maintenance in construction tunnel after advanced rig flip horizontal 180 °.
This utility model can be realized by following technical proposal:
A kind of maintenance frock of advanced rig, it is characterized in that: include two groups of rollover stands, one group of rollover stand is for supporting one end of front rig assembly, another group rollover stand is for supporting the other end of front rig assembly, each group of rollover stand is combined by upper semi-frame and lower semi-frame, and is provided with cushion block and it is fixed temporarily.
Described upper semi-frame is welded to form by a piece of upper outer ring, many upper connecting rods, a piece of upper inner ring, a piece of upper backup pad, a piece of upper gussets, and upper outer ring, upper inner ring two ends are fixed with upper gusset, and upper link supports is between upper outer ring and upper inner ring.
Described lower semi-frame is welded to form by a piece of lower outer ring, many lower links, a piece of lower inner ring, a piece of lower supporting plate, a piece of lower web plates, and lower outer ring, lower inner ring two ends are fixed with lower web plate, and lower link is supported between lower outer ring and lower inner ring.
Described upper outer ring be a piece of diameter be 1700mm, wide 140mm, the semi-circular sheet steel of thick 6mm, upper connecting rod 1 is 30mm × 45mm, and thickness is the rectangular steel pipe of 4mm, upper inner ring be a piece of diameter be 700mm, wide 90mm, the semi-circular sheet steel of thick 6mm, upper backup pad is thickness 10mm, and five steel plate butt weldings of width 140mm form.
Described lower outer ring be a piece of diameter be 1700mm, wide 140mm, the semi-circular sheet steel of thick 6mm, lower link is 30mm × 45mm, and thickness is the rectangular steel pipe of 4mm, lower inner ring be a piece of diameter be 700mm, wide 90mm, the semi-circular sheet steel of thick 6mm, lower supporting plate is thickness 10mm, and nine steel plate butt weldings of width 140mm form.
After using said structure: shield excavation machine is the narrowest and small in the space, job site of tunneling, when advanced rig occur hydraulic pressure, electrically, mechanical breakdown time, directly cannot keep in repair on shield excavation machine, need to disassemble advanced rig to overhaul and safeguard, the installation station of advanced rig be rock drill down, needing to utilize a special auxiliary mould will to implement maintenance after advanced rig flip horizontal 180 ° in construction tunnel, after having keeped in repair, flip horizontal 180 ° attaches it on shield excavation machine again.
Accompanying drawing explanation
