Description

Technical Field

[0001] The utility model relates to the technical field of detection aids, in particular to a hydraulic lock switch detection aid. Background Art

[0002] The hydraulic lock is essentially composed of two hydraulically controlled one-way valves. As the name suggests, the hydraulic lock is a "lock" that locks the circuit and prevents the oil in the circuit from flowing, so as to ensure that the cylinder can remain stationary even when there is a certain load outside.

[0003] After the hydraulic lock is produced, the switch of the hydraulic lock needs to be tested. By installing the nozzle of the air pump on the oil inlet of the hydraulic lock, the gas is pressed inside the hydraulic lock to push the piston inside to move it, so that it moves left and right to test opening and closing.

[0004] However, when the existing detection auxiliary tool is used to detect the hydraulic lock, the staff needs to manually fix the nozzle of the air pump on the hydraulic lock before performing the detection. After the detection is completed, it needs to be disassembled again, which is troublesome and cumbersome.

[0005] In addition, when testing the hydraulic lock, the staff needs to manually place each hydraulic lock that needs to be tested on the testing auxiliary tool, and the existing testing auxiliary tool cannot automatically move the hydraulic lock that needs to be tested to the testing position.

[0013] Preferably, the workbench fastener is connected to a display, the display is connected to an air pump via a line, and one end of the one-way threaded column is connected to a second motor via an output shaft.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] First, the utility model can automatically detect the hydraulic lock by setting a nozzle and a bidirectional threaded column. When the hydraulic lock moves to the top of the nozzle, the first motor is turned on, and the first motor drives the bidirectional threaded column to rotate through the output shaft. The rotation of the bidirectional threaded column drives the two threaded blocks to move in relative or opposite directions through the forward thread and the reverse thread to move the rubber pad to the top of the oil return port. Then the telescopic motor is turned on, and the telescopic motor drives the rubber pad below to be squeezed on the oil return port of the hydraulic lock through the output shaft. Then the second motor is turned on, and the second motor drives the unidirectional threaded column to rotate through the output shaft. The unidirectional threaded column The threaded column drives the nozzle to move upward through the thread, so that the nozzle moves to the oil inlet at the bottom of the hydraulic lock, and then the air pump is turned on. The air pump sprays high-pressure air through the nozzle into the interior of the hydraulic lock to detect whether the piston inside the hydraulic lock can move to open and close. When the piston is opened, the gas is discharged to the outside through the pressure relief pipe on the rubber pad. A valve is provided on the pressure relief pipe to release pressure only when there is a certain pressure. After the detection is completed, the motor is controlled to rotate in the opposite direction to complete the automatic detection of the hydraulic lock switch. There is no need to manually install the air pump. It is simple and quick, which reflects the practicality of this device.

[0016] Second, the utility model can automatically load the hydraulic valve that needs to be tested by setting up a conveyor belt and an elastic member. The pressure relief valve that needs to be tested is placed inside the hopper, and the hydraulic valve falls onto the supporting block below through the hopper. The elastic member pushes the conveyor belt through the telescopic column, so that the conveyor belt clamps the two sides of the hydraulic valve. Then the conveyor belt rotates to drive the hydraulic lock to move until it moves to the testing position, thereby achieving the work of automatically loading the hydraulic lock. There is no need for staff to manually load the materials, which saves time and effort and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
