Part must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.
As Figure 1-4, the utility model provides a kind of servicing unit for adjusting shield machine hinged oil cylinder hinge angle, bag
Include：
Basic cushion block 17, it is that two detachable connections of semicircular cylinder 4 and 5 form hollow cylindrical structure, the basis
Cushion block 17 is sheathed on outside hinged oil cylinder piston rod 2.Several small cushion blocks 6, it is square sheet structure, the small cushion block 6 one
Side caves inward to form groove 11, and the groove 11 is arranged to engage that (diameter of the center position of groove 11 is slightly larger than
The diameter of hinged oil cylinder piston rod 2) on hinged oil cylinder piston rod 2.When in use, based on basic cushion block 17, Ke Yigen
Hinge angle is adjusted according to the quantity of the needs constantly plus-minus small cushion block 6 of angle, and the weight of small cushion block 6 is smaller easy to operation.
Further, in the servicing unit of described regulation shield machine hinged oil cylinder hinge angle, two semicircular cylinders 4 and 5
Direction of the both ends of interconnection along its basal diameter stretches out to form otic placode 14, and two semicircular cylinders 4 and 5 pass through otic placode 14
Connection.
Further, in the servicing unit of described regulation shield machine hinged oil cylinder hinge angle, two semicircular cylinders 4 and 5
On wherein side otic placode 14 it is be hinged by hinge 7, the otic placode of opposite side is connected by bolt 8, be hinged mutually to be tied with bolt connection
The connected mode of conjunction makes the dismantling connection between described two semicircular cylinders more convenient.
Further, the first end of semicircular cylinder towards hinged oil cylinder pedestal 3 has chamfering 16, and the chamfering 16 can be be hinged oil
Cylinder pedestal 3 coordinates contact, increases the compactness of semicircular cylinder and oil cylinder pedestal 3, is more uniformly stressed it.
Further, the second end relative with its first end on the semicircular cylinder is fixed with integrally formed perpendicular to otic placode
Gusset 15, two the first round tube holes 13 are symmetrically arranged with the gusset 15 of one of semicircular cylinder, are symmetrically arranged with small cushion block 6
Two the second round tube holes 12, two round tube holes 12 of the first round tube hole 13 and second are corresponding to be fixed by spring holder 9, bullet
Spring alignment pin 9 can limit free movement degree of the small cushion block 6 on piston rod 2, realize the Dual positioning of small cushion block 6, make small cushion block 6
Positioning become more accurate, conveniently.
Further, antifriction scrubbing pad is installed with the inwall of basic cushion block 17 and the groove inner wall, due to base mat
Block 17 and small cushion block can slide in pressurized process on oil cylinder, so may due to the friction damage oil cylinder between contact surface,
Set antifriction scrubbing pad 10 can prevent basic cushion block 17 and small cushion block from causing to damage to oil cylinder in pressurized process.
When the application is directed to most of hinged oil cylinder failure in shield machine tunneling process, shield machine hinged oil cylinder
Posture be unable to adjust automatically, at this moment need the mode of artificial addition cushion block to control hinged oil cylinder stroke, so as to adjust hinge
The size of angle is connect, to reach the purpose of attitude regulation or turning.Required pad thickness is calculated before cushioning cushion block, is calculated
Afterwards by hinged oil cylinder reach needed for stop (stretching out for rough oil cylinder of estimating herein after the distance that can pad into of cushioning cushion block
Distance), fixed after basic cushion block 17 is padded with bolt, different-thickness and the pulvinulus of quantity are added according to the size calculated
Block, fixed between small cushion block and basic cushion block 17 with spring holder, it can be moved rearwards automatically after hinged oil cylinder stress, until
Hinged oil cylinder and the distance of pedestal 3 reach setting value (gross thickness of added basic cushion block 17 and small cushion block) and stopped afterwards, can be effective
Prevent the abrasion to piston rod 2.According to execute-in-place experience, the thickness range of required cushion block regulation between 70mm-120mm,
The thickness of design basis cushion block 17 is 60mm, and the species that small cushion block thickness has 5mm, 6mm, 7mm, 8mm, 9mm distinguishes some pieces.
The construction of servicing unit is utilized in the utility model, is comprised the following steps：
Step 1: the shield machine thrust oil cylinder 20 that bounced back under pressurize pattern, makes cutter head of shield machine be separated with face, preferably
The distance of propelling cylinder of retraction shield machine be 1-3cm, in the progradation of constructing tunnel, hinged oil cylinder 21 goes out shield machine
During existing problem, the retraction of small distance can reduce the release resistance of hinged oil cylinder, make cutter head of shield machine under soil pressure effect
Separated with face, so as to reduce energy consumption.
Require to stretch out size to being more than Step 2: stretching out hinged oil cylinder, be hinged oil is rule of thumb adjusted during practical operation
The stroke of cylinder piston rod 2, and basic cushion block 17 is sheathed on the piston rod 2 of hinged oil cylinder, then pass through live actual requirement
The small cushion block of the sized corresponding thickness of selection is fastened on hinged oil cylinder piston rod 2.
Tunneled at a slow speed Step 3: opening the propulsion system of shield machine 22, by the hinged oil cylinder of stretching under soil body reaction force
Cylinder body 1 push back dieback on cushion block, formed fitting driving axis deflection, so as to solve in existing shield machine be hinged oil
The problem of maintenance difficulty is big after cylinder goes wrong.Using cushion block seized piston bar 2, oil cylinder is seted to cause to be hinged from being fully retracted
The generation of angle.
Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and embodiment
Listed utilization, it can be applied to various suitable fields of the present utility model completely, for those skilled in the art,
Other modification is easily achieved, therefore under the universal limited without departing substantially from claim and equivalency range, this reality
