Embodiment 1

[0020] Such as figure 1 The rear frame of a loader shown includes a left web and a right web, the front of the left web and the right web are connected by a hinge seat 8, and the rear is connected by a tail plate 4 to form a frame; the left web The plate is composed of the left front web section 1 and the left rear web section 2, the rear end of the left front web section 1 is provided with a limiting groove 1-1, and the front end of the left rear web section 2 is provided with a limiting groove with the left front web section 1. The limit boss 2-1 matched with the bit groove 1-1, such as figure 2 , image 3 , Figure 4 As shown; the right web is composed of the right front web section 7 and the right rear web section 6, the rear end of the right front web section 7 is provided with a limit groove 7-1, and the front end of the right rear web section 6 is provided with the right front web section The limit boss 6-1 matched with the limit groove 7-1 of the plate section 7, s...

Embodiment 2

[0022] The difference between this embodiment and Embodiment 1 is that: the left rear web section 2 and the right rear web section 6 of this embodiment are both integral solid cast steel, and the left front web section 1 and the left rear web section 2 The right front web segment 7 is connected to the right rear web segment 6 through the connecting plate and bolts. All the other features are the same as in Example 1.

Abstract

The invention discloses a rear frame of a loader and relates to the technical field of engineering machinery. The rear frame comprises a left web and a right web. The left web is composed of a left front web section and a left rear web section. The right web is composed of a right front web section and a right rear web section. A left balance weight and a right balance weight are arranged on the outer side of the left rear web section and the outer side of the right rear web section respectively. The left front web section and the right front web section are both a welding part of a box type structure. The left rear web section and the right rear web section are both an integral solid part. Compared with the prior art, the strength of the left rear web section and the right rear web section is better, no rib plates need to be additionally arranged on the side face of the left rear web section and the side face of the right rear web section, installing space is saved, the left balance weight and the right balance weight are easily installed, and the left rear web section and the right rear web section further achieve the effects of the balance weights. The length sizes of the left front web section and the right front web section are small, the welding workload is reduced, time and labor are saved, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a loader rear frame. Background technique [0002] The rear frame of the loader is mainly used to install the cab and the engine. The large loader shovels a lot of materials. In order to prevent the loader from tipping over, it is necessary to add a counterweight to the rear of the rear frame. The currently used rear frame of the loader includes a left web and a right web. The front part of the plate is equipped with a cab mounting support, and the rear is equipped with an engine mounting support. Both the left web and the right web are welded parts of the box structure; the left web and the right web of the box structure are both It is welded by two opposite side plates and a plurality of sealing plates connecting the edges of the two side plates. Due to the large length and size of the left web and the right web, there are many parts, the structure is complex, t...
