Problems solved by technology

[0005] The wear-resistant components of the above-mentioned excavating equipment, when connecting the bucket teeth and the tooth holder through the connecting piece, need to be assembled by hammering vigorously. Stopping for a long time reduces the production efficiency; and because of the need to strike vigorously, the operator will have a greater safety hazard; at the same time, the force on the circlip is too large when installing and removing it, resulting in poor reusability of the circlip. There are frequent incidents of wear-resistant components coming off, therefore, further improvements are left

Embodiment 1

[0031] see figure 1 and figure 2 , a connector, applied to a wear-resistant assembly of a bucket of excavating equipment, the wear-resistant assembly includes a wear-resistant root 1, a wear-resistant tip 2 and a connector 3, and the connector 3 is inserted into the wear-resistant root 1 and the wear-resistant After sharpening part 2, connect the two and install and fix them.

[0032] see image 3 and Figure 4 , the wear-resistant root 1 is fixed on the lip plate of the bucket of the excavating equipment by means of welding, bolts, saddle pins and the like. The wear-resistant root 1 includes an assembly part 11 and an installation and fixing part 12, the assembly part 11 is used for connecting with the wear-resistant tip 2, and the installation and fixing part 12 is for connecting with the lip plate of the bucket of the excavating equipment. In this embodiment, preferably, the wear-resistant root portion 1 is fixed by welding, and the mounting and fixing portion 12 is fo...

Embodiment 2

[0049] see Figure 13 and Figure 14 , in this embodiment, the difference from the first embodiment above is that the pin shaft head 311' of the pin shaft 31' of the connector 3' is recessed to form a groove 314', and the second end of the groove 314' (the end close to the pin shaft main body 312') runs through the pin shaft head 311'. The elastic pad 32' includes a pad body 321' and two wings 322', between the two wings 322' (between the two sides in the circumferential direction), an end close to the pin main body 312' extends in the circumferential direction to form a The blocking end wall 325, the blocking end wall 325 closes one end of the receiving area 324' close to the pin shaft main body 312', and the part of the blocking end wall 325 corresponding to the first slideway 323' is provided with a gap, or the blocking end wall 325 and A gap is formed between the corresponding wings 322' of the first slideway 323', which can become an extension of the first slideway 323'...

Abstract

The invention discloses a connector of an abrasion-resistant assembly for an excavating device. The connector comprises a pin shaft and is characterized in that the side wall of the pin shaft is sunken inwards in the radial direction to form a groove; a snap spring is arranged in the groove; relative to the groove, the snap spring is limited in the axial direction of the pin shaft, and the snap spring has a certain elastic variable in the radial direction of the pin shaft; the snap spring comprises a snap spring body and a blocking protrusion extending in the axial direction of the pin shaft at the end portion of the snap spring body; the blocking protrusion divides the groove into a first slide way and a containing region which are located on the two sides of the blocking protrusion; and the first slide way further communicates with the outer side of the groove.

Description

technical field [0001] The present invention relates to excavating equipment, in particular to connectors for wear components of excavating equipment. Background technique [0002] For excavating equipment used in engineering and mining, such as excavators, bulldozers, loaders, electric shovels, draglines, etc., the front of the bucket is equipped with wear-resistant components. In this process, the wear-resistant components are subjected to severe friction and impact. [0003] The wear-resistant component usually includes a wear-resistant root, a wear-resistant tip, and a connector for fixedly connecting the wear-resistant root and the wear-resistant tip. If the wear-resistant component falls off, it will cause rapid wear of the bucket and components. At the same time, the lost wear-resistant component cannot be found, which will cause irreparable damage to the large-scale crushing equipment. Therefore, a safe connector becomes a guarantee for use. However, due to the env...
