Description
Technical field:
The utility model relates to power shovel technical field, is specially a kind of bucket bottom of electric dipper fastening devices.
Background technology:
Power shovel is the extractive equipment of opencut, and power shovel is in the process of operation, and original bucket bottom of electric dipper fastening devices (bucket the end fixed head) may wear to a certain degree, and bucket bottom of electric dipper cannot get back to original position and Guan Bushang.Bucket bottom of electric dipper fastening devices is after wear out failure, and due to the wearing and tearing of its set bolt six square toes, be difficult to dismounting, Renewal process is comparatively complicated, and longer during institute's work consuming.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of bucket bottom of electric dipper fastening devices.
A kind of bucket bottom of electric dipper fastening devices of the present utility model, comprise bucket end fixed head, stage clip, dead bolt and wearing plate, fixed head at the bottom of described bucket is provided with bucket end fastening devices draw-in groove, the stage clip of dead bolt and connection dead bolt is provided with in described draw-in groove, described dead bolt inserts the bayonet socket place that wearing plate is provided with, described wearing plate is also provided with two screwed holes, described screwed hole has been threaded bolt.
Preferably, described dead bolt is the wedge structure with certain angle.
Preferably, described bolt be M10 bolt and long threaded portion more than 15mm.
The utility model beneficial effect: when the utility model is installed by wearing plate, directly wearing plate is inserted in bucket end fastening devices draw-in groove, when needs dismounting wearing plate, be screwed into wearing plate screwed hole with bolt, when this bolt is screwed to, utilize crowbar or hand hammer just can to take out the wearing plate of wearing and tearing, can realize when bucket bottom of electric dipper fixes position serious wear easy to wear, direct replacing wearing plate, without the need to changing fastening devices at the bottom of whole bucket, Renewal process is efficient and convenient.
