Scaling hob and cutter holder for TBM test bed

Abstract

The invention discloses a scaling hob and a cutter holder for a TBM test bed. The invention belongs to the field of TBM test beds, and particularly relates to a scaling hob and a cutter holder for a TBM test bed. The problems of high cost, large mass and size, long experiment time and inconvenience in disassembly and assembly due to the fact that a hob used by a test bed is generally a hob actually used on a TBM are solved. The scheme of the invention comprises that the scaling hob comprises the cutter holder, two supports are arranged on the cutter holder, the two supports are adjacently arranged, grooves I are formed in the supports, the grooves I in the two supports are oppositely formed, bearings are arranged in the grooves I, bearing covers are arranged around the grooves I, the two bearings are connected with a same cutter shaft, the cutter shaft is sleeved with a cutter ring, and the cutter shaft is sleeved with a baffle. The device is simple in structure, the cutter ring can bedisassembled and assembled under the condition that the bearing is not taken down, follow-up analysis and detection of the cutter ring are facilitated, the experiment efficiency can be remarkably improved, and the cost is saved.

Description

technical field [0001] The invention belongs to the field of TBM test benches, and in particular relates to a scaled-down hob and a knife seat used for a TBM test bench. Background technique [0002] Full-face tunnel boring machine (TBM) is a special construction machine for tunnel excavation, with safe excavation and lining, and fast excavation speed; the whole process of advancing, excavating, and assembling lining can be automated, and the construction labor intensity is low; It affects ground transportation and facilities, and does not affect underground pipelines and other facilities; it does not affect shipping when crossing rivers, and is not affected by weather conditions such as seasons, wind and rain during construction, and has no noise and disturbance during construction. It has been widely used in railways, highways, Municipal, hydropower and other tunnel projects. [0003] In the prior art, the relevant research experiments on rock breaking and wear mechanism ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problems that the hob used in the test bench in the prior art usually adopts the hob actually used on the TBM, the cost is high, the mass volume is large, the experiment takes a long time, and it is inconvenient to disassemble and assemble. The present invention provides a TBM test bench The reduction ratio hob and tool seat, the purpose of which is: the structure of this device is simple, the cutter ring can be disassembled without removing the bearing, which is convenient for the follow-up analysis and detection of the cutter ring, which can significantly improve the experimental efficiency and save cost
