Abstract
The utility model belongs to the field of excavator equipment used in excavating plant operation, and particularly relates to an excavator connecting shaft stop pin with a guard ring, which comprises a stop pin, wherein, the guard ring with a round groove is arranged in the position where the stop pin is installed on an excavator connecting shaft, a round hole corresponding to a stop pin hole on the excavator connecting shaft is formed in the middle of the guard ring, and the stop pin passes through the round hole of the guard ring. The utility model has the benefit that the stop pin can be prevented from being directly in contact with goods, so that the stop pin is less susceptible to wear. The stop pin can remain in use for 4-6 times the service life of the conventional stop pin, thereby reducing the replacement frequency and the labor intensity of repairmen. Moreover, the stop pin with the guard ring prolongs the operation machine-hour of equipment and achieves favorable economic benefits.
Description
Technical field
The utility model belongs to the power shovel apparatus field of excavating plant operation, is specifically related to a kind of power shovel connecting axle backing pin that is provided with protection ring.
Background technology
The power shovel of excavating plant operation, power shovel scraper bowl and power shovel shovel pole junction have a plurality of connecting axles, and connecting axle all needs backing pin.Because existing backing pin is exposed to the outside, direct and goods (ore) collides, and the backing pin serious wear in very short time, had both needed to change backing pin.Increase spare parts consumption, increase maintenance worker's labour intensity, increase downtime, reduced device efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of power shovel connecting axle backing pin that is provided with protection ring, avoids backing pin directly to collide with goods (ore), reduces backing pin and weares and teares; reduce spare parts consumption; reduce maintenance worker's labour intensity, reduce equipment downtime, improved device efficiency.
The purpose of this utility model is achieved through the following technical solutions.
The power shovel connecting axle backing pin that is provided with protection ring of the present utility model; comprise backing pin; it is characterized in that being provided with the protection ring of a band circular groove at the position of the installation backing pin of described power shovel connecting axle; the middle part of this protection ring is provided with the corresponding circular hole in backing pin hole with described power shovel connecting axle, and described backing pin passes the circular hole of this protection ring.
The internal diameter 90--120 millimeter of described protection ring ring, external diameter 120--150 millimeter, width 20--40 millimeter, the wide 13--16 millimeter of described circular groove, high 17--20 millimeter are provided with the radial hole of diameter 13--15 millimeter in this circular groove.
The beneficial effects of the utility model are to avoid backing pin directly to contact with goods.After adopting this novel backing pin, the wearing and tearing of backing pin obviously reduce, and be 4-6 times of old-fashioned backing pin service time, have reduced the replacing number of times of backing pin, have reduced maintenance worker's labour intensity, when having improved the operation post of equipment, have obtained good economic benefits.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail.
As shown in Figure 1; the power shovel connecting axle backing pin that is provided with protection ring of the present utility model; comprise backing pin 3; it is characterized in that being provided with the protection ring 2 of a band circular groove 4 at the position of the installation backing pin 3 of described power shovel connecting axle 1; the middle part of this protection ring 2 is provided with the corresponding circular hole in backing pin hole with described power shovel connecting axle, and described backing pin 3 passes the circular hole of this protection ring 2.
The internal diameter 90--120 millimeter of described protection ring 2, external diameter 120--150 millimeter, width 20--40 millimeter, the wide 13--16 millimeter of described circular groove, high 17--20 millimeter.
Embodiment
At connecting axle 1, the position of original backing pin 3, the protection ring 2 of a trough of belt of installation.100 millimeters of the internal diameters of protection ring 2,130 millimeters of external diameters; 30 millimeters of width.Outside go out wide 14 millimeters, high 18 a millimeters circular groove 4,14 millimeters of two diameters of brill in circular groove 4 to the hole with the lathe car.
After adopting this novel backing pin, the wearing and tearing of backing pin obviously reduce, and be 4-6 times of old-fashioned backing pin service time, have reduced the replacing number of times of backing pin, have reduced maintenance worker's labour intensity, when having improved the operation post of equipment, have obtained good economic benefits.
