Abstract
A trapezoidal surface 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 two support plates mounted on two support legs of the trapezoidal detection surface, and a faceplate supported on the two support plates. The utility model has the beneficial effects of simple structure andextremely low cost input; the device is used for detecting the flatness of two mounting surfaces of the center cutter support leg, and guarantees that a repaired support leg can satisfy the technicalrequirements 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 tunnel machine center cutter support foot trapezoidal faces checkout gear.
Background technology:
TB880E type tunnel 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 bonding surface 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 bonding surface impaired through regular meeting; require and the cutter maintenance instruction according to technological document, the support foot that bonding surface 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 tunnel machine center cutter support foot checkout gear, 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 tunnel machine center cutter support foot trapezoidal faces checkout gear is characterized in that: be made up of the trapezoidal detection faces of support foot, two gripper shoes and the panel of frame on two gripper shoes that are installed on trapezoidal detection faces two legs.
On the above-mentioned panel handle is installed.
The beneficial effects of the utility model: simple in structure, the cost input is few.In order to detect the planeness of two installation surface of support foot, accuracy of detection height, the satisfied installation of the support foot technical requirements after therefore repairing.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 schematic diagram.
Fig. 2 is a front view of the present utility model.
Fig. 3 is the lateral view of Fig. 2.
The specific embodiment:
As shown in Figure 1, 2, 3: a kind of open type tunnel machine center cutter support foot trapezoidal faces checkout gear, form by support foot trapezoidal faces detection faces 1, two gripper shoes 3 and the panel 4 of frame on two gripper shoes that are installed on trapezoidal detection faces two legs 2.Handle 5 is installed on the above-mentioned panel.
The utility model is used for detecting the surface finish of support foot cutterhead side installed surface 6, during detection, at first on installed surface to be detected 6, smear red abrasive pastes, the utility model is positioned on to be detected 6, push-and-pull the utility model moves reciprocatingly on to be checked of support foot, after removing testing tool, need on the support foot cutterhead 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.
