Just excavate and also restricted in many cities by law and specification.At present, in pipeline construction frequently with push-bench tunneling
During, because the unequal factor of soil property makes push-bench to be promoted by design direction.At present frequently with correction oil cylinder pushing tow
Placket is rectified a deviation, and due to the deflection of angle, interference between correction oil cylinder suspension ring and base and connecting pin be present, in big load
Under condition of work, attachment means are easily damaged, it is therefore desirable to which a kind of bigger attachment means of free degree are improved.
Shown in Fig. 1, the mechanical structure of existing push-bench is mainly by rear cylinder 1, correction oil cylinder 2, placket 3, cutterhead 4 and driving
Device is formed.Floating connection is used between placket 3 and rear cylinder 1, junction is subject to sealing ring sealing.The rotation of cutterhead 4 passes through spoil disposal
Sizing device discharges soil, and rear cylinder 1 makes push-bench travel forward under the pushing tow of jack, also logical between placket 3 and rear cylinder 1
The multiple oil cylinders 2 for crossing uniform correction connect.Push-bench needs to be controlled i.e. driving route and direction in tunneling process
So-called correction, typically follow it is diligent entangle, micro- principle entangled.Qualified push-bench need to ensure there is suitable deviation adjustment angle.
Oil cylinder 2 arranged using 45 degree of cross, is divided into upper left, lower-left, upper right, four groups of bottom right, every group of two oil cylinders 2, such as
Shown in Fig. 2.Oil cylinder 2 organizes into groups work, and two adjacent groups oil cylinder 2 moves.Right correction：Upper left, lower-left oil cylinder 2 are released, upper right, bottom right two
Individual oil cylinder 2 is motionless, and realization is rectified a deviation to the right.Lower correction：Upper left, upper right oil cylinder 2 are released, and lower-left, bottom right oil cylinder 2 are motionless, realize to
Lower correction.When not considering the factors such as simplified weight, working face resistance, sealing structure resistance, the size of deviation adjustment angle depends on
In the design structure of push-bench.
Also referring to Fig. 3, Fig. 4 and Fig. 5, because push-bench placket 3 can be inclined with rear cylinder 1 generation angle during correction
Difference, so that oil cylinder 2 and the deflection (as shown in Figure 4) in the junction generation angle A direction of placket 3, or angle B direction are inclined
Turn (as shown in Figure 5).The deflection in angle B direction, make to produce interference between the suspension ring 4 of oil cylinder 2 and connecting pin 5 and base 6, such as scheme
Shown in 5.Worked for a long time under the conditions of unbalance loading, badly damaged, induction production accident, reduction production efficiency can be produced to oil cylinder 2.
