Description

Technical Field

[0001] This utility model relates to the field of tilting machinery, specifically to a hydraulic and electrical pipeline connection device for tilting machinery and the tilting machinery itself. Background Technology

[0002] Currently, in mechanical equipment requiring rotational operations, such as box-turning machines and flanging machines, the power and control systems need to be connected between moving and stationary parts. This connection of electrical and hydraulic lines between moving and stationary parts typically uses an electro-hydraulic central rotary joint. However, this joint needs to be positioned at the exact center of the rotation axis of the moving parts. With numerous electrical and hydraulic lines, their axial length along the rotating part is considerable, requiring significant space at the central axis and severely impacting the overall equipment layout. Furthermore, when there are many electrical and hydraulic lines, the rotation range of the rotating part is limited to prevent entanglement.

[0003] In addition, the electro-hydraulic central rotary joints commonly used in the prior art generally use a brush structure for the electrical connector and a heavy-duty rotating body rotary groove structure for the hydraulic connector. Furthermore, both the electrical and hydraulic connectors are separate. During the long-term operation of the electro-hydraulic central rotary joint, technical problems such as poor brush contact in the electrical connector and leakage of the rotary groove seal in the hydraulic connector may occur, resulting in a high equipment failure rate.

[0031] Reference Figure 1 The present invention relates to a hydraulic and electrical pipeline connection device for a tilting machine, comprising: a rotating component 1, a fixed component 2, a supporting roller 3, a pulley bracket 4, a fixed pulley I 5, a fixed pulley II, a movable pulley 6, a counterweight 7, and a hydraulic and electrical pipeline 8.

[0032] One end of the support roller 3 is hinged to the fixed component 2, and the other end of the support roller 3 is used to support the rotating component; so that the support roller 3 can rotate relative to the fixed component 2 within a certain angle range. When the rotating component 1 is subjected to vibration and undergoes a slight displacement, the slight rotation of the support roller 3 relative to the fixed component 2 can relieve the force and prevent damage to the rotating component.

[0033] The rotating component 1 is typically equipped with power system components such as motors and cylinders, which need to be hydraulically and electrically connected to the fixed component 2 via hydraulic and electrical pipelines.

[0034] The pulley bracket 4 includes a vertical component and a horizontal component; one end of the horizontal component is fixedly connected to the top of the vertical component, and the other end of the horizontal component is a free end; preferably, the free end of the horizontal component faces the rotating component 1.

[0035] The fixed pulley I5 is fixedly disposed at one end of the transverse component near the vertical component, and the fixed pulley II is fixedly disposed at the free end of the transverse component.

[0036] The movable pulley 6 is slidably mounted on the vertical component of the pulley bracket 4.

[0037] The counterweight 7 is fixedly installed below the movable pulley 6.

[0038] The hydraulic and electrical cables are sequentially wound around and pass through the fixed pulley I5, the movable pulley, and the fixed pulley II.

[0039] Furthermore, the number of the support rollers 3 is at least two sets, and each set of support rollers 3 is arranged opposite to each other.

[0040] Furthermore, the lateral component is angled to the vertical component, preferably perpendicular to it.

[0041] Furthermore, the vertical component is provided with a sliding groove in the axial direction, preferably a T-shaped groove; the movable pulley 6 is provided with a slider; preferably, the slider is a T-shaped block; the slider is slidably disposed in the sliding groove.

The rotating component 1 is supported by the support roller 3 and can rotate around the axis of the rotating component 1. The rotation of the rotating component 1 is a forward and reverse periodic rotation. Various power system components can be arranged on the rotating component 1 and connected to the fixed component 2 through hydraulic and electrical pipelines.

[0045] The hydraulic electrical pipeline in this invention can be connected as a whole using a flexible cable and a hydraulic hose that are continuous and uninterrupted.

[0046] In this utility model, the hydraulic and electrical pipelines are sequentially wound through the fixed pulley I5, the movable pulley 6, and the fixed pulley II, with the two ends of the hydraulic and electrical pipelines connected to the rotating component 1 and the hydraulic and electrical station, respectively.

[0047] The working principle of this utility model is as follows: The vertical component of the sliding bracket is provided with the sliding groove or the recess. The movable pulley is fixedly provided with the counterweight and the slider that cooperates with the sliding groove or the roller that rolls with the recess. When the rotating component rotates in both directions, the movable pulley will automatically tension the hydraulic and electrical pipeline under the gravity of the counterweight, so that the hydraulic and electrical pipeline is always in a taut state, ensuring that the hydraulic and electrical pipeline can be connected normally and smoothly retracted during the rotation of the rotating component, and ensuring that the hydraulic and electrical pipeline does not become entangled.

[0048] Furthermore, this utility model also provides a tilting mechanism, including the aforementioned hydraulic and electrical pipeline connection device.
