Problems solved by technology

[0005] 1) Once the contact area between the body frame and the reciprocating motion of the oil cylinder is worn out and fails, the body frame of the entire welded structure needs to be disassembled or replaced to achieve maintenance, which is inconvenient and expensive to maintain
[0006] 2) The vulnerable area is directly welded on the body frame, which is large in size and equipped with many parts of the whole machine, which brings great inconvenience to underground maintenance, and the economy and maintenance efficiency are not high

Abstract

The invention discloses an angling cylinder mounting seat, a body support and engineering machinery, wherein the angling cylinder mounting seat is used for mounting an angling cylinder. The angling cylinder mounting seat comprises mounting seat side plates and a mounting seat bottom plate, wherein one of the mounting seat side plates is provided with a reciprocating motion plane contacting with the angling cylinder, the mounting seat bottom plate is connected with the mounting seat side plates and detachably connected to the body support used for mounting the angling cylinder. According to the angling cylinder mounting seat, the body support and the engineering machinery, when the reciprocating motion plane, contacting with the angling cylinder, of the angling cylinder mounting seat is abraded and loses efficacy, the angling cylinder mounting seat is detached off alone to complete repair and replacement, and thus maintainability of equipment is effectively promoted.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a rotary oil cylinder mounting seat, a body frame provided with the rotary oil cylinder mounting seat, and construction machinery. Background technique [0002] At present, the body part of the roadheader usually includes a body frame, a turntable, a cover plate, a slewing bearing, etc., and the turntable is arranged on the body frame, and is sleeved on a rotary oil cylinder arranged on the body frame. [0003] Among them, the connection structure between the rotary cylinder and the body frame of the narrow-body roadheader can refer to figure 1 As shown, the rotary oil cylinder 12 is installed between the steel plates directly welded on the body frame 14, the steel plate is provided with a mounting block bearing table before and after, and the mounting block 13 provided on the rotary oil cylinder 12 is arranged on the mounting block bearing table, and bolts and The mounting ...
