Description

Technical Field

[0001] The utility model relates to the technical field of flow distribution devices, in particular to an expandable flow distribution device. Background Art

[0002] A splitter motor is a fluid power transmission device, also known as a multi-fluid motor or a flow distribution motor. It can distribute the input hydraulic pressure to multiple motors through fluid pipelines, thereby driving multiple working parts to move simultaneously. Existing splitter motors are generally composed of a flow distribution device, namely a splitter pump and a hydraulic motor. When the liquid enters from the oil inlet of the pump, it will be divided into multiple oil flows, and then enter multiple hydraulic motors through the splitter, thereby driving multiple parts to move simultaneously. The output torque of the splitter motor is inversely proportional to the speed of the motor, that is, the faster the speed, the smaller the output torque, and the slower the speed, the greater the output torque. When the traditional flow distribution device is working, it is impossible to observe whether the gears are running, and it is impossible to determine whether the product is running, which is not convenient for current The on-site personnel determined that the gear end faces and mating parts were damaged by wear, which led to an increase in the end face matching clearance and oil unloading problems. The working status of the pressure relief port was unknown, and it was impossible to determine whether the pressure relief pressure was normal or whether there was any pressure relief. When a fault occurred, the problematic part module could not be effectively identified, and the problematic part module could not be disassembled separately. All of them needed to be disassembled for inspection. Once disassembled, the repair and recovery situation was poor. When the equipment was re-equipped, more new problems would arise due to adaptability, degree of wear, assembly sequence and position, and faults would occur frequently. For this reason, we proposed an expandable flow distribution device. Utility Model Content

[0016] 2. The safety piston ensures that the oil flow will not be discharged. The safety piston can be reset by its own reset spring when there is no pressure. When there is pressure, the pressure makes the safety piston bulge outward. The operator can observe the status of the safety piston in real time through the transparent window.

The pressure relief holes 51 are all opened on the right side of the inside of the cylinder ring 1 and the cylinder base 2.

It is possible to observe in real time whether the working state of the pressure relief port is normal, and the parts module that needs to be repaired can be quickly disassembled and assembled.

[0032] The working principle of an expandable flow distribution device provided by the utility model is as follows: oil flows in from the oil inlet 44, and is squeezed by the upper and lower sets of gears 42 to the oil outlet 45 for use by external equipment. During this period, when the oil flow is squeezed by the upper and lower sets of gears 42, pressure will be generated. Polyethylene pads 43 are provided on both sides of the gears 42 as sealing devices to avoid the problem of wear and oil unloading. The safety piston 46 ensures that the oil flow will not be discharged. The safety piston 46 can be reset by its own reset spring in the absence of pressure. When the gear 42 squeezes the oil flow to generate pressure, the pressure causes the safety piston 46 to bulge outward. The operator can observe the state of the safety piston 46 through a transparent window 47. If the state of the piston is protruding, it indicates that there is pressure, that is, this path is working normally. The pressure relief port 54 is opened in the middle of the right side of the cylinder seat 2 located at the front end. The pressure relief port 54 is connected to the pressure relief channel, and the pressure is relieved on the side. The safety pressure value of the safety valve 52 can be set externally, and then the general assembly is carried out to ensure the accuracy of the safety pressure. A transparent window 2 53 is directly set outside the safety valve 52, so that it can be intuitively seen whether oil is discharged. After working for a period of time, when it needs to be disassembled for inspection, U-shaped grooves 31 for connecting nuts are set at the four corners of the cylinder ring 1 and the cylinder seat 2. Loosen the gasket 33 and the nut 34 to separate the gasket 33 from the surface of the adjacent cylinder seat 2. Since the U-shaped groove 31 is an open through-hole structure, the bolt 32, gasket 33 and nut 34 can be directly taken out as a whole, so that the combination of each port can be disassembled separately, and the disassembly is quick and convenient. When assembling, after positioning each part, the pre-installed bolt 32, gasket 33 and nut 34 are placed in the U-shaped groove 31 according to the installation position, and they can be tightened by slightly turning a few circles, eliminating the need to separate the parts before the bolts can be installed or removed, which is very convenient.
