Abstract
A locking mechanism for a hob shaft belongs to the filed of accessories of a shield machine and is an important part of the shield machine. The locking mechanism mainly comprises a wedge block, a bolt, a worm, a beam, a clamping spring, a worm gear and a fillet of a screw. The wedge block is installed between a hob shaft head and a hob box through the bolt, the thread end of the bolt penetrates through a step hole of the beam to be screwed tightly in a screw hole of the wedge block, the worm is installed on the beam through the fillet of the screw, the worm gear is installed in a big hole of the beam through the clamping spring and a square column of the bolt, the upper end of the bolt is provided with threads, the lower end of the bolt is provided with the square column, and the middle of the bolt is provided with a short thick cylinder. The beam is provided with the step hole with a small top and a big bottom, the worm gear is installed in the big hole, a groove used for installing the clamping spring is installed at a near-opening portion of the big hole, a special hole used for installing the worm is arranged in the back and forth direction, and the front end of the special hole is provided with a screwed hole used for installing the fillet of the screw. The front end of the worm is provided with an inner hexagon hole matched with a wrench, and the middle of the worm gear is provided with a square hole matched with the square column on the bolt. The bolt is prevented from being loosened by means of self-locking characteristics of a worm gear mechanism, stressed length of the bolt is greatly reduced, strain value of following stress is reduced, and the hob shaft is stable and reliable in locking.
Description
Technical field
The cutter shaft retaining mechanism belongs to the shield machine fitting field, is the vitals of shield machine.
Background technology
Hobboing cutter is installed on the shield machine, with multiple cutter integration of operation, accomplishes excavation, the tunneling construction in tunnels such as subway jointly; The cutter shaft retaining mechanism of present shield machine roller cutter; Bolt receives the pulling force position long, and the moving measure of nut anti-looseness owes safe, is prone to take place the fault that locking was lost efficacy in the work progress.
The utility model content
The utility model technical problem to be solved provides a kind of improved cutter shaft retaining mechanism; Make the locking of cutter shaft in construction safe reliable; Effectively prevent to lock the generation of failure of removal, mainly comprise hobboing cutter case, cutter shaft cushion block, cutter shaft, voussoir, bolt, worm screw, crossbeam, jump ring, worm gear, the fillet of screw; The cutter shaft cushion block is installed on the hobboing cutter case with lag bolt and spring washer, and voussoir is installed between hobboing cutter spindle nose and the hobboing cutter case through bolt, after the end of thread of bolt passes the stepped hole of crossbeam; Be tightened in the screw of voussoir; Worm screw is installed on the crossbeam through the fillet of screw, and worm gear is installed in the macropore of crossbeam through the tetragonal prism of jump ring and bolt, and the upper end of bolt is a screw thread; The lower end is provided with tetragonal prism, and there is short and thick circular cylinder the centre; Crossbeam offers up-small and down-big stepped hole, and worm gear is installed in the macropore, and the nearly oral area of macropore is provided with the groove that jump ring is installed, and is provided with the special hole of installation worm in fore-and-aft direction, is provided with the screwed hole that the fillet of screw is installed at the front end of special hole; The front end of worm screw is provided with the inner hexagonal hole that cooperates with spanner; The centre of worm gear be provided with bolt on the cubic hole that cooperates of tetragonal prism; The final stage of installing can be clamped the tetragonal prism twisting on the bolt with big spanner; Twist worm screw with inner hexagon spanner simultaneously, utilize the latching characteristics of worm-and-wheel gear to prevent bolt looseness, bolt is shortened by pulling force length significantly; Reduced the strain value of following stress significantly, locked safe reliable.
Description of drawings
Figure of description is the sketch map of cutter shaft retaining mechanism.Fig. 1 is a front view, Fig. 2 be among Fig. 1 along the sectional drawing of A-A, 1 among the figure is the hobboing cutter case, the 2nd, cutter shaft cushion block, the 3rd, hobboing cutter spindle nose; The 4th, voussoir, the 5th, bolt, the 6th, worm screw, the 7th, crossbeam, the 8th, jump ring; The 9th, worm gear, the 10th, lag bolt, the 11st, spring washer, the 12nd, the fillet of screw, the 13rd, tetragonal prism.
The specific embodiment
Embodiment to the cutter shaft retaining mechanism elaborates below in conjunction with accompanying drawing:
