Embodiment

[0041] The embodiment of the present application provides a skirt plate, the skirt plate is provided with a main shaft, and a plurality of skirt plate oil cylinders 500 are connected to the main shaft plate.

[0042] Each apron oil cylinder 500 for driving the apron is provided with a apron oil cylinder lifting control system respectively.

[0043] In addition to controlling the expansion and contraction of the apron oil cylinder 500 under the action of oil pressure, the lifting control system can also quickly make the faulty apron oil cylinder 500 release the oil pressure and be in a floating state when a certain apron oil cylinder 500 fails to hold pressure. The piston rod of the faulty apron oil cylinder 500 can be freely extended and retracted, so as to follow the movements of other apron oil cylinders 500 to avoid affecting the steel throwing work.

[0044] like figure 1 As shown, the apron oil cylinder lift control system includes an oil supply device, a first pressure de...

Abstract

The present application relates to the technical field of steel bar production, in particular to a skirt plate oil cylinder lifting control system and skirt plate, comprising: an oil supply device provided with a proportional valve; a first oil circuit connecting the proportional valve and a rodless cavity; The oil circuit is connected with the proportional valve and the rod cavity; the first pressure detection device is arranged in the first oil circuit and used to detect the pressure value of the first oil circuit; the second pressure detection device is arranged in the second oil circuit and used for The pressure value of the second oil circuit is detected; the third oil circuit is connected with the first oil circuit and the second oil circuit; the first shut-off valve is arranged in the third oil circuit and is electrically connected with the first and second pressure detection devices; A shut-off valve can be opened in response to the detection results fed back by the first and second pressure detection devices. When a fault occurs, the first and second pressure detection devices send a signal to the first shut-off valve to open it, so that the rod cavity and the rodless cavity are connected without stopping, so that the faulty cylinder follows the action of other cylinders. .

Description

technical field [0001] The present application relates to the technical field of steel bar production, in particular, to a skirt plate oil cylinder lifting control system and a skirt plate. Background technique [0002] The apron is relatively long, and is generally driven by multiple sets of apron oil cylinders at the same time. Once the oil supply system of one of the apron oil cylinders fails, resulting in the failure of normal oil supply and the inability of the apron oil cylinder to operate under pressure, it must be stopped immediately to deal with the fault. , the common treatment method is to temporarily cancel the faulty apron cylinder, for example: disassemble the faulty apron cylinder from the apron, and use the remaining apron cylinder to drive the entire apron lifting operation; or disassemble and connect the faulty apron The oil pipe on the oil cylinder is depressurized so that the faulty skirt plate oil cylinder can expand and contract synchronously with other...
