Full-automatic vacuum glue filling device for magnetic track brake

Abstract

The invention discloses a full-automatic vacuum glue filling device for a magnetic track brake. The full-automatic vacuum glue filling device for the magnetic track brake comprises a glue storage barrel connected with a glue feeding hole on the magnetic track brake. A glue discharge hole on the magnetic track brake is connected with a vacuum pump. A liquid level sensor is arranged in the glue storage barrel. A first vacuum sensor is arranged at the inlet of the glue feeding hole. A glue overflow detecting device and a second vacuum sensor are sequentially arranged between the glue discharge hole and the vacuum pump. The liquid level sensor, the first vacuum sensor, the second vacuum sensor and the glue overflow detecting device are all connected with a data collection module. The data collection module is connected with a PLC. The PLC is connected with an upper computer. The full-automatic vacuum glue filling device for the magnetic track brake improves encapsulation quality; during vacuum glue filling, the inner part of the magnetic track is in the vacuum state, air residue rarely exists, and bubbles, cavities and other encapsulation defects can be reduced; the vacuum state facilitates the glue to fill layer and turn gaps of a coil, the coil is firmly stuck, and the anti-vibration performance of the coil can be improved.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicle braking, in particular to a fully automatic vacuum glue filling device for magnetic rail brakes. Background technique [0002] Magnetic rail braking is a technology in the field of rail vehicle braking technology. It is a new type of braking method that uses electromagnetic attraction to generate braking force. The magnetic track brake is a special-purpose electromagnet, which is installed on the bottom of the train through a suspension device, and has a small working gap (air gap) between the magnetic pole surface and the track surface. The specific working method is to pass current into the magnetic track brake to excite the electromagnetic coil. Under the action of electromagnetic attraction, the magnetic track brake overcomes the spring tension of the suspension device and is adsorbed on the rail, generating huge friction at the contact surface between the magnetic pole and the tr...

Problems solved by technology

Its production efficiency is low. At the same time, due to factors such as the obstruction of the internal parts of the electromagnet, the flow channel is not smooth, and the air in some positions is difficult to exclude, it is often difficult to fill the internal gap of the electromagnet. There are bubbles, holes, and no glue between layers. Defects have different degrees of influence on the insulation and vibration resistance of the coil, and ultimately affect the product quality
