Description

Technical Field

[0001] This utility model relates to the field of pipeline processing technology, and in particular to an oil pipe connection device. Background Technology

[0002] On a pipe grooving production line, the power head and hydraulic circuit block of the grooving machine need to move back and forth on a linear guide rail. The hydraulic station of the machine is located at the bottom of the frame. The hydraulic oil pipe connecting the power head hydraulic circuit block and the lower hydraulic station needs to move back and forth a certain distance with the power head. In the existing technology, the hydraulic oil pipe is placed in a nylon cable chain to move with the power head. However, the cable chain will cause the oil pipe to bend, and the oil pipe is easily damaged due to bending, which will affect normal operation. Utility Model Content

[0003] The purpose of this invention is to provide an oil pipe connection device that overcomes the shortcomings of existing technologies where hydraulic oil pipes are placed inside nylon cable carriers and move with the power head, making the oil pipes prone to bending and damage.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] An oil pipe connection device is provided for connection to a hydraulic device and a power device. It includes a power device connection section and an oil circuit transfer station. The oil circuit transfer station has an oil inlet and a first oil return port connected to the hydraulic station. The oil circuit transfer station has two oil circuit channels inside: a first channel and a second channel. The first channel is connected to the oil inlet, and the second channel is connected to the first oil return port. The power device connection section includes an oil outlet, a second oil return port, a first oil pipe, and a second oil pipe. The oil outlet and the second oil return port are connected to the oil circuit of the power device. The oil outlet is connected to the first oil pipe, and the second oil return port is connected to the second oil pipe. The first oil pipe is slidably disposed within the first channel and connected to the oil inlet, and the second oil pipe is slidably disposed within the second channel and connected to the first oil return port.

[0006] The oil transfer station is box-shaped, with the oil inlet and the first return oil inlet located on one side of the oil transfer station, and the first and second channels opening on the other side of the oil transfer station; both the oil inlet and the first return oil inlet are equipped with oil nozzles.

[0007] Sealing rings are installed at the openings of the first and second channels.

[0008] Dustproof rings are installed at the openings of the first and second channels.

[0009] Oil seals are installed at the openings of the first and second channels.

[0010] The dust seals at the openings of the first and second channels are located on the outside of the oil seal.

[0011] The oil transfer station is also equipped with connecting and fixing components.

[0012] The advantages of this utility model are: it no longer uses hydraulic oil pipes wrapped with drag chains, and a first channel and a second channel are set in the fixed oil transfer station. The first oil pipe and the second oil pipe of the power device connection part are slidably set in the first channel and the second channel. When the power device connection part moves with the power device, the first oil pipe and the second oil pipe can extend or retract from the first channel and the second channel, which solves the problem of bending and damage of hydraulic oil pipes in the prior art.

[0017] The present invention will be further described below with reference to the accompanying drawings. The drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent.

[0018] To simplify the description of this embodiment, some components that are well-known to those skilled in the art but are not related to the main content of this invention may be omitted in the accompanying drawings or description. Additionally, for ease of description, some components in the drawings may be omitted, enlarged, or reduced, but these do not represent the actual product dimensions or the complete structure.

[0019] This utility model discloses an oil pipe connection device, applied in a pipeline grooving production line, which connects to the hydraulic and power devices of the pipeline grooving production line, such as... Figure 1-3 As shown, it includes a power unit connection part 2 and an oil transfer station 1. The oil transfer station 1 is used to replace the hydraulic oil pipe wrapped with nylon drag chain in the prior art. The oil transfer station 1 is provided with an oil inlet 11 and a first oil return port 12 connected to the hydraulic station. The oil inlet 11 is connected to the oil outlet of the hydraulic station, and the first oil return port 12 is connected to the oil return port of the hydraulic station.

[0020] like Figure 2 , 3As shown, the oil transfer station 1 is equipped with two oil passages, namely the first passage 13 and the second passage 14. The first passage 13 is connected to the oil inlet 11, and the second passage 14 is connected to the first return oil inlet 12.

[0021] The power unit connection part 2 includes an oil outlet 21, a second oil return port 22, a first oil pipe 23, and a second oil pipe 24. The oil outlet 21 and the second oil return port 22 are connected to the oil circuit of the power unit. The oil outlet 21 is connected to the oil inlet of the oil circuit of the power unit, and the second oil return port 22 is connected to the oil return port of the oil circuit of the power unit.

[0022] Oil outlet 21 is connected to the first oil pipe 23, and second return oil port 22 is connected to the second oil pipe 24. The first oil pipe 23 is slidably disposed within the first channel 13 and opens into the first channel 13, thereby connecting to the oil inlet 11; the second oil pipe 24 is slidably disposed within the second channel 14 and opens into the second channel 14, thereby connecting to the first return oil port 12; Figure 3 As shown, the two oil pipes can extend or retract from the two channels as the power unit slides. When the oil pipe connection device of this utility model is installed in the chute conveyor line, the hydraulic oil of the hydraulic station enters the first channel 13 of the oil transfer station 1 through the oil inlet 11. The hydraulic oil enters the first oil pipe 21 through the first channel 13 and enters the oil circuit of the power unit through the oil outlet 21. Then it flows back to the second oil pipe 24 through the second return oil outlet 22, and then flows back to the hydraulic station through the first return oil outlet 12 through the second channel 14, forming a closed-loop oil circuit composed of the hydraulic station, the oil transfer station 1, and the oil circuit block of the power unit. This solves the defect of hydraulic oil pipe bending and damage in the cable chain in the prior art.

[0023] Preferably, the oil transfer station 1 is box-shaped, with the oil inlet 11 and the first oil return port 12 located on one side of the oil transfer station 1, and the first channel 13 and the second channel 14 opening on the other side of the oil transfer station 1; to facilitate connection with the hydraulic station, both the oil inlet 11 and the first oil return port 12 are equipped with oil nozzles.

[0024] To ensure the sealing between the first channel 13, the second channel 14 and the first oil pipe 23 and the second oil pipe 24, and to prevent oil leakage, sealing rings 4 are provided at the openings of the first channel 13 and the second channel 14. Furthermore, dustproof rings 5 ​​and oil seals 6 are also provided at the openings of the first channel 13 and the second channel 14, with the dustproof ring 5 located outside the oil seal 6.

[0025] The oil transfer station 1 is also equipped with a connecting and fixing component 3, which is fixed to the bottom of the frame of the chute production line.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made within the scope of the claims of this utility model should be considered within the technical scope of this utility model.
