Embodiment 1

[0033] The hard rock roadheader main drive inner wear-resistant sleeve hole installation tool of the present invention includes a support tool 8 and a limit tool 9, and the support tool 8 passes through the fixing hole of the inner wear-resistant sleeve support ring 5 during use and is detachable It is arranged in the bolt hole of the fixed inner wear-resistant sleeve support ring 5 on one side of the upper part of the fixed support 1 of the main drive, and supports the inner wear-resistant sleeve 4; the limit tooling 9 is detachably arranged on the main drive In the bolt holes of the fixed lip-shaped sealing pressure ring 7 around the driven movable support 2, the inner wear-resistant sleeve 4 plays a position-limiting role during installation.

[0034] The support tooling 8 includes a support frame plate 801, a fixed seat plate 802, a support screw rod 803, a positioning bolt 804 and a lock nut 805. The fixed seat plate 802 is provided with a waist-shaped hole 821, and the su...

Abstract

The invention relates to the technical field of tunneling machine main driver mounting, in particular to an in-burrow mounting tool for an inner wear-proof casing hole of a main driver of a hard rocktunneling machine. The in-burrow mounting tool comprises a supporting tool and a limiting tool. When the supporting tool is used, the supporting tool penetrates through an inner wear-resisting sleevesupporting ring fixing hole and is detachably arranged in a bolt hole which is in one side of the upper portion of the fixed supporting end of the main driver and is used for fixing the inner wear-resisting sleeve supporting ring, and an inner wear-resisting sleeve is supported. When the limiting tool is used, the limiting tool is detachably arranged in a bolt hole arranged around a movable support of the main driver and used for fixing a lip-shaped sealing pressing ring, and the inner wear-resisting sleeve is limited when mounted. According to the in-burrow mounting tool for the inner wear-proof casing of the main driver of the hard rock tunneling machine, project burrow internal thermal replacement of the inner wear-resisting sleeve of the tunneling machine can be achieved, it is avoidedthat the main driver is demounted to be conveyed to a factory out of a burrow to be replaced, a large amount of transportation cost is reduced, the maintenance man hour of a shield tunneling machineis shortened, and the construction efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of installation of the main drive of a roadheader, in particular to an installation tool for the inner wear-resistant casing of the main drive of a hard rock roadheader. Background technique [0002] The installation of the main drive focuses on the installation of the wear-resistant sleeve. Currently, the wear-resistant sleeve is generally made of Stellite alloy. In order to ensure the assembly quality, the wear-resistant sleeve is usually hot-fitted. That is to say, it is necessary to prevent the expansion of the wear-resistant sleeve from being too large beyond the installation position of the support ring, and it is also necessary to prevent the temperature of the wear-resistant sleeve from cooling too quickly and causing it to be stuck on the working surface of the support ring. [0003] During the long-term excavation construction of the roadheader, the front end of the main drive is exposed to enviro...
