Description

Technical Field

[0001] The present invention relates to the technical field related to controllers, and in particular to a special controller for a hydraulic flap machine. Background Art

[0002] As a common equipment for unloading bulk materials, hydraulic flap machine is widely used in grain, coal mining, cement and metallurgy industries. With the continuous expansion of the application industry of the equipment and the substantial increase in the number of applications, the following three problems are exposed during the use of the equipment.

[0003] 1. In the prior art, hydraulic flap machines basically adopt speed regulating valves, synchronous motors or proportional synchronous control methods, but the synchronous control method is single, especially the proportional synchronous control generally adopts the method of system oil replenishment or oil unloading, the deviation correction ability is poor, and the effect is not ideal. Once the hydraulic valve in the equipment is mechanically stuck or the equipment is overloaded, due to the lack of angle control and angle alarm, the flap machine platform is very likely to be seriously tilted or even overturned, resulting in accidents, and there are great safety hazards.

[0004] 2. In the prior art, hydraulic flap machines rely on hydraulic oil as the transmission medium. However, due to the lack of temperature control and temperature alarm, the hydraulic oil is prone to volatilization and gasification in high temperature environments, and is prone to solidification and waxing in low temperature environments. The volatilization and gasification or solidification and waxing of the hydraulic oil will have a serious impact on the normal use of the hydraulic flap machine.

[0005] 3. Since the hydraulic flap machine is mostly used for temporary power supply, the power quality cannot be guaranteed; there are also high-power interference sources such as motor inverters on site. In the prior art, the electronic equipment protection circuit is simple or simply has no protection circuit, which makes the electronic equipment easily interfered, resulting in circuit damage and communication data errors, which is not conducive to the long-term use of electronic equipment, affects the maintenance and long-term use of the equipment, and cannot meet the needs of the site.
