Description
Technical Field
The invention relates to the technical field of bulk cargo loading and unloading equipment, in particular to a clamping in-place device for detecting a vertical pressing car dumper.
Background
The dumper is large mechanical equipment and can automatically dumped the granular materials loaded by the railway open wagon. In the existing dumper system, the pressing mode is various, the vertical pressing mode is wide in adaptation to the vehicle type, each pressing beam is controlled by an independent hydraulic system, and the stability is improved compared with other modes, so that the dumper is widely applied. The car pressing beam is controlled by a hydraulic system, and the detection means of whether the car pressing beam presses the carriage is judged by a pressure signal in a car pressing beam oil cylinder.
Under normal conditions, the set value of the pressure signal of the car pressing beam is adjusted according to the actual condition on site so as to ensure that the car pressing beam can be pressed on a carriage when the set value of the pressure is reached. However, in the production process, the pressure is often caused to reach a set value due to the fact that the pressure is stopped halfway in the process of pressing Liang Kazu and the pressing process, and the actual position of the pressing beam is not in contact with the carriage for compaction, and in this case, the system considers that the tipping condition is met and the car is caused to break away from the railway wheel pair and the track due to the fact that the car is tipped over, and the design principle of the hydraulic system cannot guarantee that the pressing beam and the carriage are pressed in place when the pressure reaches the set value. The current railway system is also very strict in checking the accidents. The accidents delay production and cause great loss.
The current similar method is that the detection element is installed on the pressing vehicle Liang Lian, firstly, the pressing vehicle beam descends to start the pressing vehicle action, and when the detection pressure head contacts the carriage, the detection pressure head is triggered to send a signal to the PLC control system when moving upwards to the induction range of the detection element. The method has the defects that the connection cable of the detection element moves up and down along with the trolley beam because the trolley beam moves up and down in the slideway (shown in figure 1), the cable is easy to break and damage, and materials fall on the cable when the dumper is tipped over, so the reliability and stability of the method for installing the detection element on the trolley beam are not high.
Aiming at the current situation, a new method for improving the reliability and stability of the clamping detection of the pressing beam is urgently needed, and the new method can reduce the loss and bring benefit to manufacturers and users and has the value of market popularization.
