During the development of underwater instruments, hydrostatic tests must be carried out in a laboratory in order to examine their ability to adapt to the underwater high-pressure working environment. The existing hydraulic test system comprises a pressure sealed cabin and a lifting device, wherein the lifting device lifts a sealed end cover of the pressure sealed cabin and puts a test sample of an instrument into a port of the pressure sealed cabin.
Fig. 1 shows the basic structure of a prior art hydraulic test system, including a pressure-tight chamber and a lifting device. The lifting device comprises a transverse travelling mechanism, a longitudinal travelling mechanism and a lifting mechanism. The longitudinal running mechanism is arranged on two longitudinal guide rail beams 7m away from the ground, 3m in span and 10m in stroke and consists of two parallel guide rails, two parallel cross beams with the span of 1m, a motor, a speed reducer, a power distribution device and a wireless receiver. The transverse traveling mechanism is arranged on the guide rails of two parallel beams with the span of 1m of the longitudinal traveling mechanism and consists of a motor, a speed reducer, traveling wheels below the beams and a wireless receiver. The hoisting mechanism is arranged on the transverse travelling mechanism and comprises a motor, a speed reducer, a steel cable, a lifting wheel and a lifting hook, wherein the lifting hook is arranged at the lower end of the steel cable. The wireless receivers of the transverse travelling mechanism and the longitudinal travelling mechanism are respectively connected with the speed reducer and the power distribution device.
When the existing hydrostatic test system works, a tester utilizes a wireless controller to control the transverse traveling mechanism and the longitudinal traveling mechanism to move through a wireless receiver, the hoisting mechanism is moved to the upper part of the pressure seal cabin, then the steel cable and the lifting hook are released, a related detection instrument is hoisted into the pressure seal cabin, the seal end cover is buckled on the pressure seal cabin, and then the detection instrument is subjected to a high-pressure test in the pressure seal cabin. After the test is finished, the detection instrument is taken out of the pressure seal cabin and the seal end cover is reset to the original storage area by using similar operation.
The whole process of the hoisting device of the existing hydraulic test system is manually operated, and the hoisting device is difficult to move and position accurately. Several problems sometimes arise:
1. the sealing end cover and the end face of the pressure-resistant cabin cannot be accurately butted to meet the sealing requirement of a test, and a pressure-resistant watertight plug at the lower end of the sealing end cover is extremely easy to crush in the butting process;
2. the test sample connected with the sealing end cover is easy to collide with the periphery in the processes of horizontal transportation and vertical placement in a pressure-resistant cabin, so that damage is caused;
3. when the sealed end cover is lifted after the test is finished, the sealed end cover cannot be normally lifted due to the fact that the position of the lifting device is not accurate, and the sealed end cover and the side wall of the sealed cabin are rubbed in the lifting process, so that the service life of the sealed cabin is influenced; meanwhile, the deviation of the lifting hook from the center of the pressure chamber can cause the abrupt increase of the stress of a steel wire on the lifting hook of the hoisting device, so that the damage of an operating mechanism of the hoisting device, the fracture of the steel wire and the falling of a hoisting part are caused;
4. the hoisting device is too random on a walking line, so that the test equipment is easy to operate on the top of a tester or equipment, and the damage of laboratory equipment and detected equipment and the casualty accidents of the laboratory equipment are easy to cause.
In conclusion, the existing hydraulic test system lifting device has the defects of poor precision, low efficiency and poor safety guarantee by means of visual judgment of personnel, and cannot meet the requirements of efficient and safe test lifting in a current laboratory under a space compact working condition.
