Description

Technical Field

[0001] The utility model relates to the field of boosters, in particular to an oil drain device for auxiliary boosters. Background Art

[0002] In the helicopter control system, the hydraulic booster is an important device that reduces the pilot's control load. Before installing the main rotor booster, the hydraulic oil in the booster cavity must be drained so that the booster can be adjusted to the appropriate length to ensure that it can be connected to the booster support and automatic inclinometer.

[0003] The current method for draining oil from a booster is for two operators to pull the fork ears at both ends of the booster and press the booster oil valve to drain the excess oil from the booster. This method of operation places a heavy load on the operators and is inefficient. Summary of the Invention

[0004] The present application provides an auxiliary booster oil discharge device, which can reduce the operating load of the operator and improve work efficiency.

[0005] Technical solution: This application provides an auxiliary booster oil discharge device, which includes a movable wheel 1, a fixed wheel 2, a jack 3, a bracket body 4, a rear baffle 5, a side baffle 6, an oil receiving pan 7, and a fixed joint 8, wherein:

[0006] The bracket body 4 includes a first bracket 4-1 and a second bracket 4-2. The first bracket 4-1 and the second bracket 4-2 are both square frame structures. The first bracket 4-1 is placed horizontally, and the second bracket 4-2 is arranged on the first bracket 4-1 in a vertical direction.

[0007] The connector 8 is in the shape of a U-shaped fork ear;

[0008] The oil receiving pan 7 is a square box;

[0009] The movable wheel 1 and the fixed wheel 2 are installed on the bracket body 4 to ensure that the device can move at each station; the jack 3 is fixedly connected to the bracket body 4, and the jack is used to support the bracket body when in use to ensure that it does not move or tip over; the rear baffle 5 and the side baffle 6 are riveted to the bracket body 4 to prevent the booster from splashing when discharging oil and polluting the operation site; the oil collecting pan 7 is placed on the inside of the bracket body 4 to collect the hydraulic oil discharged by the booster; the fixed joint is welded to the upper part of the bracket body 4 to fix the booster.

[0010] Specifically, the height h of the bracket body 4 is greater than the total length of the maximum stroke of the booster, ensuring that the booster can move to the maximum stroke.

[0011] Specifically, the inner width l of the fixed joint 8 is greater than the width of the booster mounting ball head, ensuring that the booster can be installed.

[0012] Specifically, the oil receiving pan 7 is a movable part, not welded to the bracket body 4, and is used for collecting and draining oil.

[0013] Specifically, the bracket body 4 is a metal bracket body.

[0014] Specifically, the oil collecting pan 7 is airtightly welded to ensure that the oil does not leak after being collected.

[0015] In summary, this application provides an auxiliary booster oil draining device. The auxiliary bracket is moved to the position where the booster oil needs to be drained. The jack is rotated to support the bracket. The booster is installed on the fixed joint. The booster oil valve is repeatedly pressed to drain the hydraulic oil from the booster cavity. The oil pan is removed and the remaining oil in the oil pan is poured into the residual oil storage tank in the factory. This new device can effectively assist in draining the hydraulic oil in the booster cavity and reduce the operating load on workers. BRIEF DESCRIPTION OF THE DRAWINGS
