The invention relates to the field of large mining excavators, in particular to a bucket lip assembly connecting structure of a large mining excavator. The invention aims at achieving the technical purposes that the safe and reliable bucket lip assembly connecting structure of the large mining excavator is provided, sliding friction between all components is small, and operation is easy. The bucket lip assembly connecting structure of the large mining excavator comprises a bucket lip and a mounting base, wherein the bucket lip and the mounting base are each provided with a mounting hole, and the mounting holes are matched with each other; the bucket lip assembly connecting structure further comprises a clamping plate, a wedge and a conical stud, wherein the clamping plate, the wedge and the conical stud are arranged in the mounting holes, the conical stud is arranged between the clamping plate and the wedge, the surface of the clamping plate and the surface of the wedge are both provided with thread structures matched with threads of the conical stud, and the bucket lip and the mounting base are tightened in a wedged mode through the clamping plate and the wedge by screwing the conical stud. According to the connecting structure, a screwing tool with a lengthened rod can be adopted, so that labor is saved, and efficiency is also high; various potential safety hazards caused by hammering are avoided, and safety and reliability are achieved. The bucket lip assembly connecting structure is especially suitable for mounting a bucket lip assembly of the large mining excavator.
Description
technical field [0001] The invention relates to the field of large mining excavators, in particular to a large mining excavator bucket lip assembly connection structure. Background technique [0002] The excavator bucket is one of the main working devices in the large-scale mining excavator. The bucket is mainly composed of bucket teeth, bucket body, bucket bottom, equalizing beam, balancing pulley, and various connecting accessories. It adopts a cast-welded structure. , The main stress and wear-resistant parts are made of high-strength wear-resistant alloy cast steel. The lip assembly is located on the front wall of the bucket body and is susceptible to mineral wear. The bucket body is made of alloy steel plate, and the bucket lip is a large low-alloy steel casting, which is fixed on the front wall of the bucket body by welding and is not easy to replace. The tooth seat is connected to the bucket lip through a C-shaped clamp and a wedge, and the tooth seat is also connect...
