Description
Technical field
The present invention relates to rotary device field is torn open in shield body hole, in particular to a kind of TBM shield body is anti-to sidewinder walking support device
And application method.
Background technique
The driving hole diameter of TBM is 8.13m, a height of 4.065m in hole center, there was only the gap 35mm between anterior shield shell and hole wall,
There was only the gap of 80mm between branch pole and hole wall.In so small driving hole, it is impossible to remove the shield body portion of TBM development machine
Point, it is therefore necessary to shield body is tunneled into hole from hole diameter for 8.13m, the sliding rail being laid with along hole bottom, sliding walking 20m, is walked to hole forward
The gateway opening type for rising 14.2m digs in hole.Since TBM shield body diameter is more than 8m, more than 680 ton of weight, cylindrical shield body is two
Item height is less than when sliding is walked forward on 28cm sliding rail, it is easy to slideway is detached from, to two side roll unstabilitys.To digging in hole
The equipment equipment such as door machine damages, and damages to the constructing operation personnel at scene, security risk is very big.
Support roller box is sidewindered and compression elasticity disappears the combination running gear for answering block to form by anti-, exactly prevents shield body to two sides
Roll the special-purpose machines and tools of design.The device is symmetrically welded on block two sides under anterior shield, that is, solves cylindrical TBM development machine shield
Body is easy the construction difficult problem to two side roll unstabilitys when gateway opening type tunnel slides and walks.A part of anterior shield lotus can be undertaken again
It carries, reduces pressure of the anterior shield on slideway.
Summary of the invention
In order to solve the above technical problems, the present invention proposes TBM shield body and prevents sidewindering walking support device and application method, this device

Two outsides be arranged symmetrically slideway be installed, be respectively arranged with the track being arranged symmetrically on the outside of two slideways；The rolling
The anterior shield of the top braces shield body in road, slideway and track, the two sides of the bottom of the anterior shield are symmetrically fixedly installed with for preventing shield
Body sidewindered in moving process it is anti-sidewinder support roller box, the anti-bottom for sidewindering support roller box and track constitute to slide and match
It closes；The anterior shield is connected with the hauling power device for driving it along raceway, slideway and track travel.
The wharf portal crane track being arranged symmetrically is respectively arranged on the outside of the track.
The hauling power device includes rack winch, and the traction steel rope of cable of the rack winch bypasses multiple groups movable pulley
Group and fixed pulley group, and be connected by equalizer pulley with the anti-twisting equipment for preventing steel cable from reversing, the running block passes through
Strap is connected with the traction ear mount of anterior shield two sides of the bottom.
The tail portion of the anterior shield is connected with external extension shield, and the inside of the external extension shield is equipped with interior flexible shield, described interior
The tail portion of flexible shield is fixed with branch pole；Anterior shield, external extension shield, interior flexible shield and branch pole collectively form shield body structure.
The railway limit is fixedly mounted on inside channel steel.
It is described it is anti-sidewinder the upper support structure that support wheel case includes block bottom under the anterior shield for being symmetrically welded at anterior shield, it is described on
The bottom support of support construction is equipped with leg structure, is hingedly equipped with support roller box, the support in the bottom of leg structure
Roller box support is in orbit.
The upper support structure includes upper flange plate, and vertical plate, the vertical plate are welded at the top of the upper flange plate
The support seat gusset of muti-piece parallel arrangement is welded between upper flange plate, block under the top of the support seat gusset and anterior shield
Outer wall is welded and fixed.
The leg structure includes lower flange plate, and the lower flange plate is fixedly linked by bolt and upper flange plate, under
