Description

Technical Field

[0001] The utility model relates to an oil-driven multi-cylinder tension damper, in particular to the structure of the oil-driven multi-cylinder tension damper. Background Art

[0002] Oil-driven multi-cylinder tension dampers are widely used in petroleum equipment and marine equipment.

[0003] The tension damper of the prior art is mainly composed of a large cylinder and a large piston. Since the large piston reciprocates in the large cylinder for a long time, the wall of the large cylinder and the large piston will be worn over time. In addition, the existing large cylinder and large piston are both castings. Since the castings need to be cast by model molds, the manufacturing cost is high and the manufacturing cycle is long, which will greatly increase the subsequent maintenance cost and repair manufacturing cycle. Utility Model Content

[0004] The utility model provides an oil-driven multi-cylinder tension damper, aiming to solve the above-mentioned problem.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] The utility model includes: a rotating component group; the rotating component group is connected to the main shaft of the mechanical equipment; the rotating component group includes: a damper seat, a damping plate assembly; the damping plate assembly includes: a damping plate fixing plate, a damping plate; the damping plate is thermally bonded to the damping plate fixing plate by glue; the damping plate fixing plate is splined to the damper seat and moves relative to the axial direction; it also includes: a fixed component group; the fixed component group is connected to the frame of the mechanical equipment; the fixed component group includes: a cylinder head, 4 small transition cylinder sleeves, 4 small pistons, 4 small sealing rings, 4 O-rings, a screw group, a connecting bolt group, a positioning sleeve group, a nut group, a reset spring group, a thrust flange, Damping flange, positioning flange; the four O-rings are respectively installed on the four small transition cylinder sleeves, the four small transition cylinder sleeves are respectively installed in the four hole cavities of the cylinder head through the screw group, the four small sealing rings are respectively installed on the four small pistons, and form sealing cavities with the four small transition cylinder sleeves for sealing; the connecting bolt group connects the cylinder head, the positioning sleeve, the thrust flange, the damping flange and the positioning flange together, and is tightened by the nut group; the thrust flange, the damping flange and the positioning flange are supported on the positioning sleeve, and can move axially relative to the positioning sleeve, there is a reset spring group between the thrust flange and the damping flange, and there is also a reset spring group between the damping flange and the positioning flange.

[0007] Compared with the prior art, the utility model has the following beneficial effects: since the oil-driven multi-cylinder tension damper is mainly composed of a cylinder head, four small transition cylinder sleeves and four small pistons, and since the cylinder head is a casting, the casting needs to be cast in a model mold first, so the manufacturing cost is high and the manufacturing cycle is long. In order to facilitate the later maintenance and replacement, four small transition cylinder sleeves are added between the cylinder head and the four small pistons. Even if the cylinder wall is worn, it is not necessary to replace the cylinder head, but only the four small transition cylinder sleeves and the four small pistons. The four small transition cylinder sleeves and the four small pistons are steel parts, and the processing of steel parts is simple, so the processing cost is low and the processing cycle is short, thereby reducing the later maintenance cost and the maintenance manufacturing cycle. Due to the above characteristics of the oil-driven multi-cylinder tension damper, the later maintenance cost and the later maintenance manufacturing cycle of the product are reduced, and it has a broad prospect for promotion and application.

[0012] The working principle of the utility model is as follows: when the mechanical equipment needs to stop, the hydraulic oil from the outside enters the sealed chamber composed of the cylinder head 2, 4 small transition cylinder sleeves 5, 4 small pistons 3, 4 O-rings 13 and 4 small sealing rings 4 through the oil inlet B, pushing the 4 small pistons 3 to move rightward, pushing the thrust flange 12, and pressing the damping plate assembly against the damping flange 14 and the positioning flange 15 against the return spring group 10; due to the friction force between the friction surface of the damping plate 16 and the thrust flange 12, the friction surface of the damping flange 14 and the friction surface of the positioning flange, it is transmitted to the damper seat 1 through the damping plate fixing plate 11 to achieve a slip stop. When the hydraulic oil is discharged from the oil inlet B, the 4 small pistons 3 and the thrust flange 12 are pushed to the left under the action of the return spring group 10, and the damping plate assembly is loosened from the damping flange and the positioning flange, and the damper works normally.
