Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic pipe joints, in particular to an energy dissipation right-angle hydraulic pipe joint. Background Art

[0002] Hydraulic pipe joints are components in hydraulic systems that connect high-pressure oil pipes.

[0003] When the hydraulic pipe joint is in use, the right-angle hydraulic pipe joint is mostly used for some positions in the hydraulic equipment that need to be connected to the steering part. The hydraulic pipe joint will generate a certain pressure when transporting the hydraulic oil. The hydraulic oil will have a large impact force on the corner of the right-angle pipe joint. The impact force is borne by the threaded base of the pipe joint, and the hydraulic pipe joint cannot dissipate the impact force generated by the hydraulic oil impact. The hydraulic pressure will be under continuous impact of pressure, which will seriously affect the connection sealing of the pipe joint, causing the nut on the threaded base to loosen, causing hydraulic oil leakage. The continuous impact of the hydraulic oil on the corner of the hydraulic pipe joint will affect the service life of the hydraulic pipe joint, and then affect the efficiency of hydraulic oil transportation.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4The energy dissipation right-angle hydraulic pipe joint comprises a hydraulic pipe joint body 1, wherein the hydraulic pipe joint body 1 has an arc surface, and it is supplemented that the two ends of the hydraulic pipe joint body 1 can be connected to the oil pipe and can transport the hydraulic oil;

[0022] The hydraulic pipe joint body 1 is respectively fixedly mounted with a support 1 2, a support 2 3, and a sleeve 7. A pipe 4 is connected between the support 1 2 and the support 2 3, and both ends of the pipe 4 are provided with sealing pads 5 extending into the support 1 2 and the support 2 3. It is additionally explained that the pipe 4 is a hose;

[0023] Both ends of the pipe 4 are provided with reinforcement plates 6 corresponding to the support 1 2 and the support 2 3, and the reinforcement plates 6 are threadedly connected with locking bolts corresponding to the support 1 2 and the support 2 3. The two ends of the pipe 4 can correspond to the support 1 2 and the support 2 3, and the reinforcement plates 6 are connected to the support 1 2 and the support 2 3 through the locking bolts;

[0024] When the hydraulic oil enters the hydraulic pipe joint body 1 through the oil pipe, a part of the hydraulic oil will enter the pipe 4 through the support 1 2, and the hydraulic oil will impact the pipe 4, and the pipe 4 will buffer the impacted hydraulic oil, slowing down the flow rate of the hydraulic oil. When the hydraulic oil is discharged through the support 2 3, it can impact the hydraulic oil in the hydraulic pipe joint body 1, thereby reducing the impact force of the hydraulic oil.

[0025] A buffer assembly for buffering the hydraulic oil is installed in the sleeve 7;

[0026] The buffer assembly includes a guide rod 8 fixedly installed in the sleeve 7, and a moving cylinder 9 is slidably sleeved on the guide rod 8, a spring 10 corresponding to the guide rod 8 is welded between the moving cylinder 9 and the sleeve 7, the guide rod 8 is tilted and corresponds to the arc surface, the guide rod 8 and the sleeve 7 guide the moving cylinder 9, so that the moving cylinder 9 can smoothly pull the moving rod 11 and the moving plate 12 when moving;

[0027] The spring 10 is vertically arranged at the lower end position of the moving cylinder 9 extending into the sleeve 7, the moving cylinder 9 is integrally connected with a moving rod 11, and a moving plate 12 corresponding to the hydraulic oil is rotatably mounted on the moving rod 11;

[0028] The movable plate 12 and the movable rod 11 extend to the lower end position outside the sleeve 7, and the movable plate 12 is tilted and corresponds to the arc surface. A spring 13 is welded between the movable plate 12 and the sleeve 7. When the hydraulic oil impacts the movable plate 12 through the hydraulic pipe joint body 1, the movable plate 12 will deflect and resist the movable rod 11 when subjected to force. The movable rod 11 drives the movable cylinder 9 to slide on the guide rod 8 when subjected to force. The spring 10 is subjected to force, so that the movable plate 12 can buffer the arc surface after deflection, and also dissipate energy of the hydraulic oil.

[0029] The functional principle of the utility model can be explained through the following operation modes:

[0030] The hydraulic pipe joint body 1 is installed at a designated position to transport hydraulic oil;

[0031] The hydraulic oil enters the hydraulic pipe joint body 1;

[0032] A part of the hydraulic oil impacts the moving plate 12 through the hydraulic pipe joint body 1. When the moving plate 12 is subjected to force, it deflects with the moving rod 11 as a fulcrum. At the same time, the spring 13 is subjected to force. After being impacted, the moving plate 12 resists the moving rod 11 and slides with the moving cylinder 9 in the sleeve 7, so that the moving cylinder 9 slides on the guide rod 8 and drives the moving plate 12 to buffer the arc surface. The spring 10 is subjected to force. The movement of the moving plate 12 can reduce the impact of the hydraulic oil on the arc surface.

[0033] A portion of the hydraulic oil rushes into the pipe 4 through the support 1 2, and the impact force of the hydraulic oil itself can impact the pipe 4. The hydraulic oil in the pipe 4 continues to flow and is discharged into the hydraulic pipe joint body 1 through the support 2 3, and impacts the hydraulic oil in the hydraulic pipe joint body 1, and then impacts the flowing hydraulic oil, so that the hydraulic oil can be smoothly transported.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
