Embodiment 3

[0047] Embodiment 3: A method for disassembling and assembling a portable hob cutter system. The installation steps of the portable hob are as follows: S1: Put the block 5 into the cutter box 1, as shown in Figure 6 as shown,

[0048] S2: Assemble the threaded rod 404 and guide rod 406 in the locking push-pull mechanism 4 on the tool box plate 1, and assemble the anti-loosening washer 401 on the threaded rod 404 to prevent the threaded rod 404 from loosening;

[0049] S3: Assemble the cover plate 403 on the knife box 1 and tighten it with bolts, so that the cover plate 403 presses the anti-loosening washer 401 to prevent the anti-loosening washer from shaking;

[0050] S4: Put the slider 405 into the limit groove 8 on the two side walls of the tool box 1, and then thread the threaded rod 404 to the slider 405;

[0051] S5: Drive the slider 405 to move along the axial direction of the threaded rod 404 by turning the threaded rod 404, and install the hob 3 in the cutter box 1 ...

Abstract

The invention discloses a portable hobbing cutter system and a dismounting method thereof. With the portable hobbing cutter system and the dismounting method thereof, the problems that a robot is lowin cutter changing work efficiency and poor in fusion with an existing hob in the prior art are solved. The hobbing cutter system comprises a cutter box and a hobbing cutter, wherein a clamping blockused for clamping and fixing a hobbing cutter shaft is arranged on the inner wall of the cutter box, a push-pull locking mechanism is arranged on the cutter box, a sliding block is in threaded connection with the lower part of the push-pull locking mechanism, and the sliding block is matched with the hobbing cutter shaft. The push-pull locking mechanism is connected with the sliding block and a box body in a threaded mode, the push-pull locking mechanism is controlled and operated by a tool changing robot, a nut is rotated to drive a threaded rod to rotate, and then the sliding block makes translational motion up and down, so that whether the hobbing cutter shaft is tightly pressed or not is detected, rapid and accurate tool changing is achieved, the matching degree with the tool changingrobot is high, and the tool changing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of shield hobs, in particular to a portable hob tool system and a method for disassembling and assembling thereof. Background technique [0002] During the construction process of the full-face tunnel boring machine, the tool consumption is large and the replacement is frequent. The tool change operation time accounts for more than 10% of the tunnel construction cycle. The existing tool change work mainly relies on manual work, and the construction environment such as large buried depth and high water pressure There are great safety hazards in the underground operation, and major safety accidents such as casualties are prone to occur. According to statistics, nearly 70% of tunnel construction safety accidents in China are directly related to manual tool change operations. The international industry problem of "tool change risk" has become a bottleneck restricting the safety and efficiency of tunnel construct...
