Walking protection device and method of material piling and taking machine

Abstract

The invention relates to the field of walking protection of material piling and taking machines, in particular to a walking protection device and method of a material piling and taking machine. According to the walking protection device of the material piling and taking machine, a shell is fixedly mounted on a bottom plate, and one end of a rotating shaft penetrates the shell and is mounted on the shell through a bearing; a pressure pushing plate is arranged outside the shell and is fixedly connected with one end of the rotating shaft through a swing block; a touching rotating block is arranged in the shell and is fixed to the other end of the rotating shaft in a sleeved manner; and a reset spring is arranged on the rotating shaft, and microswitches are arranged in the shell and are matched with the touch rotating block. According to a walking protection method of the material piling and taking machine, two touch positions including an alarm position and a stop position are provided, and when the pressure pushing rod is blocked by a barrier to rotate to the stop position, the microswitches send signals to a controller, and the controller directly stops walking of the material piling and taking machine. No matter how the structural mode of the material piling and taking machine is changed, mounting and detecting use of the protection device are not affected, normal operation of the device is ensured, and accident losses are reduced.

Description

technical field [0001] The invention relates to the field of running protection of a stacker-reclaimer, in particular to a running protection device and method for a stacker-reclaimer. Background technique [0002] In the current running of the stacker-reclaimer, the ballast track is a commonly used carrier for the stacker-reclaimer, and the ballast track is a means to ensure the movement of the stacker-reclaimer. Once material accumulation occurs on the track of the ballast bed, it will not only lead to disadvantages in the running of the stacker-reclaimer; at the same time, it will also have an adverse effect on the operation of the driving equipment of the stacker-reclaimer. forced outage. If it cannot be found in the first time, the fault will be enlarged, which will increase the difficulty of subsequent maintenance operations and double the maintenance cost. However, from the perspective of existing technologies, there is a lack of a better detection method when probl...

AI Technical Summary

Problems solved by technology

The existing cleaning method can only clean the stacker-reclaimer to run normally on the ballast bed track without contacting obstacles on the track, and cannot detect whether there is accumulated material on the edge of the ballast bed track that affects the normal running of the cart. Material, can not get the feedback signal at the first time to disconnect the control cart walking power

In the light case, it will damage the driving equipment of the stacker-reclaimer moving on the track; in the case of severe material accumulation, the running wheel of the cart will fall off the track; in addition, the track cleaning device only plays the role of removing obstacles on the track when the cart is running. Therefore, this device only removes track obstacles in general; and the material accumulation medium around the track of the ballast bed is the main force point that affects the movement of the stacker-reclaimer. The accumulation of material ar
