Abstract
A trapezoidal groove detection device for a center cutter support leg of an open tunnel boring machine is characterized in that the device comprises a trapezoidal support leg detection surface and twosupport plates mounted on two support legs of the trapezoidal detection surface, and the support legs of the trapezoidal detection surface are upwardly arranged. The utility model has the beneficialeffects of simple structure and extremely low cost input; the device is used for detecting the flatness of a trapezoidal support leg mounting groove, and guarantees that a repaired support leg can satisfy the technical requirements of installation due to high detection precision; and upon another failure, the support leg can be further repaired within a certain limit, thereby greatly prolonging the actual service life of the support leg (the average service life can be prolonged by no less than 3 times of the original one).
Description
Technical field:
The utility model belongs to a kind of flight-line maintenance equipment, particularly a kind of TB880E type open type rock tunnel(ling) machine center cutter support foot dovetail groove pick-up unit.
Background technology:
TB880E type rock tunnel(ling) machine is manufactured and designed by German WIRTH company, center cutter is positioned at the centre of cutterhead, is made up of 6 single-blade disk cutters, because the requirement of mounting means, center cutter at first is to be fixed on the support foot (sequence number 6), is fixed on the cutterhead with bolt (sequence number 1) again.Between support foot and the cutter and the faying face between support foot and the cutterhead, have relatively high expectations.In the tunneling process because the stressed complexity of center cutter; operating mode is comparatively abominable; cause faying face impaired through regular meeting; require and the cutter maintenance instruction according to technological document, the support foot that faying face damages must be scrapped, and this part adopts import parts always; unit price is higher; be about 12000 yuan, every group switching centre cutter needs 6 of support foots altogether, is unfavorable for reducing the cutter consuming cost.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and provide a kind of open type rock tunnel(ling) machine center cutter support foot dovetail groove pick-up unit, this device is realized the support foot maintenance with minimum input, and the support foot performance of reparation and structure satisfy the requirement that the continuation installation is used.
The technical solution of the utility model is: a kind of open type rock tunnel(ling) machine center cutter support foot dovetail groove pick-up unit is characterized in that: by the trapezoidal detection faces of support foot, be installed in two back up pads on trapezoidal detection faces two legs; The support foot of trapezoidal detection faces upwards is provided with.
Between above-mentioned two back up pads carrying handle is housed.
The beneficial effects of the utility model: simple in structure, the cost input is few.In order to detect support foot the flatness of dovetail groove is installed, the accuracy of detection height, the support foot after therefore repairing satisfies the installation technical requirement.As going wrong once more, still can continue within the specific limits to repair, prolong the actual life of support foot greatly, can reach original 3 times or higher average life.
Description of drawings:
Fig. 1 is a center cutter support foot synoptic diagram.
Fig. 2 is a front view of the present utility model.
Fig. 3 is the vertical view of Fig. 2.
Embodiment:
As shown in Figure 1, 2, 3: a kind of open type rock tunnel(ling) machine center cutter support foot dovetail groove pick-up unit, form by the trapezoidal detection faces 1 of support foot, two back up pads 3 and the promotion 4 of frame on two back up pads that are installed on trapezoidal detection faces two legs 2.
The utility model is used for detecting the surface smoothness of support foot cutter side installed surface 5, during detection, at first on installed surface to be detected 5, smear red abrasive pastes, the utility model is positioned on to be detected 5, examination criteria face 1 is fitted with to be detected 5, push-and-pull the utility model moves reciprocatingly on to be checked 5 of support foot, after removing the utility model, need on the support foot cutter side installed surface can find the position of grinding, then adopt the angle grinding machine to cooperate blinds wheel or sand paper to cooperate dull and stereotyped file to carry out grinding; Detect grinding out-of-flatness position after the processing once more, till meeting installation requirement.
