Abstract
The utility model relates to a front bracket of the oscillating bracket of electric scraper which has an arbor and is characterized in that the middle part of the arbor is a cylindrical platform. The front bracket of the oscillating bracket of electric scraper in the utility model changes the cylindrical step structure of the middle part of the arbor of the front bracket of the oscillating bracket into a cylindrical platform to eliminate the stress concentration at the transition part of the arbor, improve the strength of the arbor, make the arbor less prone to breakage, reduce the probability of malfunction in the apparatus, improve the reliability of the apparatus and reduce the cost of maintenance.
Description
Technical field
The utility model relates to electric LHD, especially a kind of electric LHD swing span fore-stock.
Background technology
Existing electric LHD swing span fore-stock axle is a cylinder step axle (as Fig. 2), often takes place in the use excessively to locate phenomenon of rupture along the cylinder step.Its main cause is that the cylinder step excessively exists stress to concentrate and fracture place strength deficiency in the place, produces tired micro-crack and make cracks can spread then under the fluctuating load effect, causes the axle fracture.Because fracture often takes place, cause equipment dependability to descend, the equipment service efficiency reduces, and the maintenance of equipment cost increases.
Summary of the invention
The purpose of this utility model just provides a kind of simple in structure, electric LHD swing span fore-stock that security performance is good.
Electric LHD swing span fore-stock of the present utility model comprises axle, and the centre that is characterized in axle is the Rotary-table structure.
Electric LHD swing span fore-stock of the present utility model, by changing swing span fore-stock axle mediate cylindrical ledge structure into the Rotary-table structure, eliminated the stress concentration phenomenon of axle transition position, increased axle intensity, make not easy fracture of axle, reduce equipment fault, improved the reliability of equipment, reduced maintenance cost.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the prior art constructions schematic diagram.
The specific embodiment
A kind of electric LHD swing span fore-stock comprises axle 1, and the centre that is characterized in axle 1 is a Rotary-table 2.
Claims (1)
1, a kind of electric LHD swing span fore-stock comprises axle (1), it is characterized in that: the centre of axle (1) is Rotary-table (2).
