Detailed Description

The technical scheme provided by the invention is described in more detail below with reference to fig. 1 to 7.

Referring to fig. 1 to 3, an embodiment of the present invention provides a turret including a collar plate 1 and a connection assembly 2. The collar plate 1 comprises a through hole 11 therethrough. The connection assembly 2 includes a first plate 21, a second plate 22, and a first riser 23. One side surface of the first flat plate 21 comprises a first arc-shaped section 211, and the first arc-shaped section 211 is entirely attached to the outer wall of the ring plate 1; one side surface of the second plate 22 comprises a second arc-shaped section 221, and the second arc-shaped section 221 is all attached to the outer wall of the ring plate 1; the first plate 21 and the second plate 22 are arranged in parallel; the first vertical plate 23 is fixedly connected with the first flat plate 21 and the second flat plate 22, and the first vertical plate 23 is positioned on one side of the first flat plate 21 away from the ring plate 1.

In some embodiments, the turret is integrally configured to be symmetrical with respect to the diameter of the coil plate 1. Two connecting assemblies 2, a guard plate 3 and a scraper knife 6 are arranged on the periphery of the ring plate 1 as seen in the circumferential direction of the ring plate 1. The structure of the grader at the ring plate 1 is symmetrically arranged relative to the diameter of the ring plate 1, and the bearing performance of the revolving frame is more balanced and stable.

Specifically, the number of the connection assemblies 2 is two, and the two sets of connection assemblies 2 are symmetrical with respect to the diameter of the collar plate 1.

Referring to fig. 6a to 6c, the ring plate 1 is configured in a circular ring shape, which is a symmetrical structure, and the ring plate 1 is symmetrical with respect to its own diameter D. The ring plate 1 is a monolithic plate, for example, it is manufactured by casting or the like.

The connecting component 2 is positioned on the outer side of the ring plate 1 and is fixedly connected with the outer wall of the ring plate 1. The inner wall of the ring plate 1 is used for installing a supporting ring seat so as to realize the rotation of the component. The number of the connection members 2 is, for example, two. The ring plate 1 and the two connecting assemblies 2 can be welded and fixed, riveted and fixed or fixed through connecting pieces such as bolts. The outer walls of the two connecting assemblies 2 and the ring plate 1 are attached, so that the contact area of the ring plate 1 and the connecting assemblies 2 is effectively increased, and only welding seams of the ring plate 1 and the connecting assemblies 2 are arranged in the stress concentration area of the revolving frame, so that the bearing property of the revolving frame is good, and the bearing is more balanced and stable.

In some embodiments, each connection assembly 2 comprises two box structures. The two box-shaped structures are sequentially arranged along the length direction of the first riser 23. Each box structure has compact structure, strong bearing, compression resistance and bending resistance. The following is a sequential description.

Referring to fig. 3 to 5, the connection assembly 2 includes a first flat plate 21, a second flat plate 22, and a first riser 23. The first plate 21 and the second plate 22 are attached to the outer wall of the collar plate 1, and the first plate 21 and the second plate 22 pass through the portion where stress is concentrated in the turret. The stress concentration position of the rotary ring is determined by the bearing condition of the rotary frame. The first plate 21 and the second plate 22 are each a single piece of plate, and are not formed by splicing and welding a plurality of plates. The first riser 23 is also arcuate in shape and is also a unitary structure and is not formed from a plurality of plates or components that are patched and welded together.

Along the length direction of the second plate 22, the second plate 22 is narrow toward one end of the shield plate 3 and wide away from the other end of the shield plate 3. The first plate 21 and the second plate 22 are both configured to meet the requirements of the blade 6 to be described later.

Referring to fig. 3 and 4, one end of the first flat plate 21 is configured as a first stepped surface 212; the first step surface 212 intersects the first arcuate segment 211. The lower portion of the first stepped surface 212 provides a relief space for the installation of the first sleeve 27, and the first sleeve 27 is attached to and welded to the outer wall of the collar plate 1. The securement of the second sleeve 28 at the upper portion of the first step surface 212 provides a mounting base, and the second sleeve 28 is welded to the upper portion of the first step surface 212. The central axes of the first sleeve 27 and the second sleeve 28 coincide, and the first sleeve 27 and the second sleeve 28 are spaced apart in the axial direction, i.e., along the axial direction of the first sleeve 27 or the axial direction of the second sleeve 28, with a gap between the first sleeve 27 and the second sleeve 28. This clearance provides a mounting space for the later-mentioned installation of the cylinder 7.
