DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

First, hydraulic oil is injected into the hydraulic rod body 1 through the oil filling port 3, and then as the hydraulic oil increases, it rises through the detection port 2, and then the hydraulic oil makes the metal ball 25 float up, and the metal ball 25 lifts up the detection rod 24 while floating up, so that it is convenient for the user to observe the scale on the outer surface of the detection rod 24 to understand the progress of adding hydraulic oil, a detection rod 24 is arranged at the top of the detection port 2, and a metal ball 25 is arranged at the bottom of the detection rod 24, and the shaft surface of the metal ball 25 is abutted with a second limit block 26, one end of the second limit block 26 is fixedly installed on the hydraulic rod body 1, and a piston rod 9 is arranged inside the hydraulic rod body 1.

When the piston rod 9 moves, the connecting piece 17 is driven, and the connecting piece 17 drives the second connecting rod 16, so that the second connecting rod 16 moves up and down along the outer surface of the threaded rod 13, thereby improving the stability of the equipment. The first limit block 14 at the top of the threaded rod 13 prevents the component from falling off, and the second connecting rod 16 is provided at the top of the first connecting rod 10. The outer surfaces of the first connecting rod 10 and the second connecting rod 16 are threadedly installed by bolts 11.

The first limit block 14 is fixedly installed at the top of the threaded rod 13.

[0020] Furthermore, a ring 5 is sleeved on the axial surface of the piston rod 9. When the piston rod 9 moves, the infrared generator 6 and the infrared receiver 8 arranged on its outer surface are in a start-up docking state. The distance between the infrared generator 6 and the infrared receiver 8 on both sides is used to detect whether the synchronous hydraulic cylinder is in a normal state. If the distances on both sides are the same, it is normal. Otherwise, the equipment fails. An infrared generator 6 is arranged at one end of the ring 5, and a mounting plate 7 is arranged on one side of the base plate 4. An infrared receiver 8 is fixedly installed at the bottom end of the mounting plate 7.

[0021] Furthermore, an installation box 18 is provided at one end of the base plate 4, and an alarm light 19 is provided at the top of the installation box 18 at the rear end of the base plate 4.

When a fault occurs on one side of the synchronous hydraulic cylinder, the measured distance will be different, and then it can be detected whether the device is in a normal state. When the hydraulic rod body 1 fails, the alarm light 19 and the sound 27 are used to remind the maintenance personnel, and at the same time, a signal is sent to the wireless signal module 22 through the external device, so that the controller 20 controls the battery 23 to stop powering the device to prevent damage to the device.
