Embodiment Construction
[0020] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention is capable of various changes in different embodiments without departing from the scope of the present invention, and that the description and drawings therein are illustrative in nature and not limiting. this invention.
[0021] like Figure 1-Figure 3 Shown is a structural schematic diagram of the electromagnetic manual integrated control valve of the present invention. The material of the present invention adopts aluminum alloy material with high and low temperature resistance, corrosion resistance and strong sealing performance, including main valve body 1, auxiliary valve body 2, main electromagnetic valve body 3 and auxiliary electromagnetic valve body 4, which can realize lifting, intermediate There are four actions of stop, quick drop and slow drop. When the inlet 50 is c...

The invention discloses an electromagnetic manual-control integrated control valve which comprises a main valve body, an auxiliary valve body and a main electromagnetic valve body. An inlet, a first channel, a second channel, a third channel and a third outlet which is communicated with the inlet through the third channel are arranged on the main valve body. A control device for manually controlling on and off of the first channel, the second channel and the third channel is positioned on the main valve body. A fourth channel, a first outlet, a second outlet, the extending first channel and the extending second channel are arranged on the auxiliary valve body, the second outlet is communicated with the inlet through the second channel, the first outlet is communicated with the inlet through the first channel, the first channel is further communicated with the second channel through the fourth channel, the fourth channel and the first outlet are interlocked, and the fourth channel is in a normally-closed state. The main electromagnetic valve body is arranged close to the auxiliary valve body and can open the fourth channel through a first switching device when being powered on. When a self discharge cargo compartment of a truck is lifted in place, the electromagnetic manual-control integrated control valve can be directly and automatically switched to descending motion to avoid rollover accidents.
Description
technical field [0001] The invention relates to a hydraulic control system of an automobile, in particular to a control device for container unloading in the hydraulic system of the automobile. Background technique [0002] At present, many trucks use self-unloading technology, and the unloading of the self-unloading box is carried out by manual control. Present self-unloading control can only rely on artificial control to carry out. When the car lifts the cargo box to unload the cargo, the conventional operation is to rely on people to judge and control. Misjudgment and slow hand control often occur in this way, resulting in rollover accidents when the car is unloaded. The current control method has huge potential safety hazards. Due to human error, it may cause huge property losses and even endanger the lives of personnel. Therefore, how to automatically and reliably unload the dump container is a difficult problem that the industry needs to solve urgently. Contents o...
