Steel ball selecting and conveying device

Abstract

The invention relates to a steel ball selecting and conveying device. A steel ball funnel is included and used for loading and outputting steel balls one by one. A fulcrum mechanism hinged to one endof the steel ball funnel and used for providing a rotation shaft for the steel ball funnel and a power mechanism connected with the steel ball funnel and used for driving the steel ball funnel to swing around the fulcrum mechanism are further included. Compared with the prior art, through electric drive, manpower can be saved, continuous operation can be achieved, and a base is provided for automation achieving.

Description

technical field [0001] The invention relates to a rail transit maintenance device, in particular to a steel ball selection and delivery device. Background technique [0002] The doors of rail transit vehicles need to be installed with steel balls to protect the relevant structures. At present, the steel balls are usually installed in the form of long ball funnels, such as figure 1 As shown, because the steel ball in the steel ball funnel is easily stuck in the leakage position, the steel ball cannot go out of the column normally. [0003] If it is necessary to use a vibrator to prevent the steel ball from blocking the leakage position for a long time, since the vibrator generally needs to be installed at the bottom, it is necessary to redesign the steel ball funnel, and the outlet channel of the funnel needs to be designed with a lateral inclination, otherwise, the eccentric The installed vibrator will cause the center of the steel ball funnel to be unstable. If it leaves l...

[0002] The doors of rail transit vehicles need to be installed with steel balls to protect the relevant structures. At present, the steel balls are usually installed in the form of long ball funnels, such as figure 1 As shown, because the steel ball in the steel ball funnel is easily stuck in the leaking position, the steel ball cannot go out of the column normally

[0003] If it is necessary to use a vibrator to prevent the steel ball from blocking the leakage position for a long time, since the vibrator generally needs to be installed at the bottom, it is necessary to redesign the steel ball funnel, and the outlet channel of the funnel needs to be designed with a lateral inclination, otherwise, the eccentric The installed vibrator will cause the center of the steel ball funnel to be unstable. If it leaves like this, the original discharge method using the gravity of the steel ball will inevitably be affected, reducing the discharge efficiency, and the vibrator is not convenient to install and use, and the cost performance is low. Therefore, it is currently commonly used. The best way is to use manual shaking, which will cause increased labor costs and low production efficiency
