Automatic reset car arrester for cage

Abstract

The invention discloses an automatic reset car arrester for a cage. The automatic reset car arrester comprises a left side tumbler car arresting block, a left side vertical limiting plate, a right side tumbler car arresting block and a right side rail track slip mechanism; the left side tumbler car arresting block and the right side tumbler car arresting block are connected to a cage chassis through pin shafts, and can rotate around the pin shaft under the self weight effect, the back face of the left tumbler car arresting block and the back face of the right tumbler car arresting block are tightly adjacent to the outer side face of an upper rail of the cage chassis, and the upper ends of the left tumbler car arresting block and the right tumbler car arresting block extend out of the uppersurface of the upper rail of the cage chassis, the left side face of the left side vertical limiting plate is tightly attached to the right side face of the left side tumbler car arresting block, theupper end of the left side vertical limiting plate is fixed to the lower face of the cage chassis, the left side tumbler car arresting block and the right side tumbler car arresting block can block left and right moving of a vehicle between the left side tumbler car arresting block and the right side tumbler car arresting block through the left side vertical limiting plate and the right side railtrack slip mechanism. The problems that in the prior art, damage is prone to happening, overhauling and maintaining are tedious, occupied space is large, and cost is high are solved.

Description

technical field [0001] The invention relates to the technical field of shaft hoisting in coal mines, in particular to a cage automatic reset car stopper. It is mainly suitable for blocking vehicles inside the cage of coal mine vertical shaft transportation and hoisting machinery and equipment. technical background [0002] The car arrester inside the cage is an important mechanism in the hoisting of the coal mine shaft. Its function is to fix the position of the mine car in the cage and avoid sports car accidents during the lifting process of the mine car. Currently, there are two types of structure for the internal car arrester of the cage: one is the manual tank stopper: the tank stopper structure is installed on both sides of the cage, and the assembly can be manually opened or closed when the mine car enters and exits the tank, which is easy to operate and occupies less space. The space inside the tank is small; however, there are potential safety hazards in this struct...
