Problems solved by technology

[0002] With the development of frequency conversion technology, we can change the loading frequency according to our needs and complete different load loading tasks. Although there are various frequency conversion technologies on the market, such as motor frequency conversion speed regulation technology, PWM hydraulic valve frequency control technology, etc., but these Frequency conversion technology can only be said to change the frequency of the same order, and often cannot meet some complex situations, such as the need for two-order loads to change with demand, so according to needs, on the basis of its first-order frequency conversion device, the pulse modulation principle and multi-cavity The structure of the hydraulic cylinder can change the size of the loading load multiple times in any time in the spatial direction of different orders. For example, when changing the size of the first order loading load, the second order or higher order can be changed at the same time or within a set time. Load the size of the load to realize the effect of heterogeneous loading

Embodiment Construction

[0015] The invention is a different-time loading device that can realize different frequency load loading. The device is composed of an electric motor 2, a hydraulic pump 3, a three-position five-way electromagnetic hydraulic valve 7, a pulse modulator 5, a computer 6, and a multi-cavity hydraulic cylinder 8. The electric motor 2 is connected with the hydraulic pump 3 to provide power for the hydraulic pump 3; the pulse modulator 5 and the computer 6 are connected with the solenoid coil of the three-position five-way electromagnetic hydraulic valve 7 to control the output flow of the valve; the multi-chamber hydraulic cylinder 8 is connected with The three-position five-way electromagnetic hydraulic valve 7 is connected to provide different loads of different sizes through the chambers with different cross-sectional areas. The device uses the modulation effect of the pulse signal and the structure of the multi-cavity hydraulic cylinder to change the size of the loading load mul...

Abstract

The invention relates to a different-time loading device. The different-time loading device is mainly composed of a motor, a hydraulic pump, a three-position five-way electromagnetic hydraulic valve,a pulse modulator, a computer and a multi-cavity hydraulic cylinder. The different-time loading device is a loading device which does not exist at present, the magnitude of loaded loads is changed multiple times within any time in the different-order space direction through the modulating effect of pulse signals and the structure of the multi-cavity hydraulic cylinder, and then multi-order loadingof the loads with the different magnitudes is achieved.

Description

Technical field: [0001] The invention relates to a heterogeneous loading device. By using the modulation effect of a pulse signal and a multi-cavity hydraulic cylinder structure, the size of the loading load can be changed multiple times at any time in the space direction of different steps, thereby realizing multi-step loading of different sizes. Background technique: [0002] With the development of frequency conversion technology, we can change the loading frequency according to our needs to complete different load loading tasks. Although there are various frequency conversion technologies on the market, such as motor frequency conversion speed regulation technology, PWM hydraulic valve frequency technology, etc., these Variable frequency technology can only say that the frequency of the same order is changed, and it is often unable to meet some complex situations, such as the need for two-step load to change with demand. Therefore, based on its first-order frequency conversion...
