Detailed Description

In order to clearly illustrate the technical features of the present solution, the present invention is explained in detail below by means of specific embodiments and with reference to the attached drawings.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

As shown in fig. 1-3, the electric shovel door square pin jack structure comprises a square pin jack body, wherein a plate body 2 is convexly arranged on the inner side wall of an electric shovel door 1, and the square pin jack body is arranged in the plate body in a penetrating manner along the height direction of the electric shovel door; set up strengthening rib 3 on the plate body inside wall of square pin jack body four corners department, the strengthening rib is the right angle deep floor that sets up along the hole degree of depth of square pin jack body, right angle deep floor and the plate body inside wall welded fastening of square pin jack body four corners department. The top wall of the end part of the plate body is provided with a lacing wire 4. The plate body 3 is an isosceles trapezoid plate body, and the lacing wire is an inverted U-shaped lacing wire arranged on the top wall of the end part of the isosceles trapezoid plate body. The inverted U-shaped lacing wire is 80mm thick.

Two wear-resisting plates 7 which are arranged oppositely are arranged in the square pin jack body in the direction perpendicular to the electric shovel door, and each wear-resisting plate is fixedly welded with two adjacent right-angle reinforcing rib plates.

The plate body 2 comprises two side plates 5 welded and fixed with the inner side wall of the electric shovel door and a connecting cover plate 6 welded between the two side plates; the two side plates and the connecting cover plate form an isosceles trapezoid plate body; the square pin jack body is arranged in the middle of the isosceles trapezoid plate body; the connecting cover plate 6 is a 60mm thick common plate. Compounding wear-resistant strips 8 on the outer sides of the connecting cover plates, wherein the wear-resistant strips are high-chromium alloy wear-resistant strips; the wear-resistant strips comprise a plurality of wear-resistant strips arranged at intervals outside the connecting cover plate. And a plurality of wear-resistant strips 8 are also arranged outside the side plates in a compounding manner.
