Abstract
The utility model relates to a hard rock entry driving machine is with central sword clamping device belongs to road, hydraulic engineering technical field, and it is fragile to have solved prior art kind wedge internal thread aperture overlength time service screw thread, and then leads to central sword to damage at work, can force central sword to drop even, and the initiation accident causes staff's personal safety to receive the technical problem of threat, the utility model discloses a girff, supporting shoe, central sword end cover still include the self -locking nut, from aligning gasket, wedge and bolt, processing has the through -hole on the wedge, the wedge passes through the inclined plane contact with central sword end cover, and the bolt passes supporting shoe, girff and wedge in proper order to through locking from aligning gasket and self -locking nut, this device has reduced the processing degree of difficulty, has improved production efficiency, and has guaranteed staff's personal safety effectively.
Description
Technical field
The utility model belongs to road, hydraulic engineering technical field, is specifically related to a kind of hard rock mole center cutter clamping device.
Background technology
See accompanying drawing 1, the clamping device of prior art development machine center cutter comprises girff 1, back-up block 2, bolt I 3, center cutter end cap 4 and wedge I 5; Described wedge I 5 inside is processed with screwed hole; Wedge I 5 and center cutter end cap 4, by contact of incline plane, together with back-up block 2, girff are bolted with wedge, make wedge I 5 pairs of center cutter end caps 4 play the power supporting direction, and then play fastening effect.Bolt I 3 pairs of wedges I 5 carry out fastening being specially, bolt I 3 is threaded with screwed hole, the screw thread of this connected mode wedge I 5 internal thread hole after working long hours is easily damaged, wedge I 5 is caused to coordinate imprecision with center cutter end cap 4, wedge I 5 pairs of center cutter end caps 4 do not have the effect of compression, and then cause center cutter to damage at work, and center cutter even can be forced to come off, accidents caused, cause the personal safety of staff to receive threat.
Summary of the invention
The purpose of this utility model is to provide a kind of hard rock mole center cutter clamping device, solve prior art kind wedge internal thread hole fragile through the screw thread that works long hours, and then cause center cutter to damage at work, center cutter even can be forced to come off, accidents caused, cause the personal safety of staff to receive the technical problem of threat.
A kind of hard rock mole center cutter of the utility model clamping device comprises girff, back-up block, center cutter end cap, also comprises self-locking nut, Self-aligning pad, wedge and bolt; Described wedge is processed with through hole; Wedge and center cutter end cap pass through contact of incline plane, screw bolt passes back-up block, girff and wedge, and by Self-aligning pad and self-locking nut locking.
The internal diameter of the through hole on described wedge is greater than the external diameter of bolt, and bolt coordinates with the via clearance of wedge.
Described screw bolt passes back-up block, girff and wedge, and by Self-aligning pad and self-locking nut locking be specially: aligning pad be enclosed within bolt the end of thread and with wedge tip contact, self-locking nut lock bolt.
Advantageous Effects of the present utility model: the utility model comprises wedge, bolt, Self-aligning pad and self-locking nut, wedge is processed with through hole, wedge and center cutter end cap pass through contact of incline plane, screw bolt passes back-up block, girff and wedge, and by Self-aligning pad and self-locking nut locking, efficiently avoid the damage of wedge, ensure that the abundant combination of bolt and wedge simultaneously, the direction of guarantee power, increases the fastening effect of wedge to center cutter end cap; This device reduces difficulty of processing, improves production efficiency, in use reduces the probability that wedge is destroyed, saves raw material; And effectively ensure that the personal safety of staff.
