Description
Technical Field
The utility model relates to a mine car accessory field specifically is a mine car bolt from taking blocking device.
Background
According to the fourth hundred sixty-six provisions of coal mine safety regulations: when the inclined roadway is used for transportation, the connection between the mine cars and the steel wire ropes need to use a connecting device which can not automatically fall off, and a safety rope is additionally arranged. At present, for the realization of regulation, a bolt anti-drop ring is commonly used for locking a mine car bolt for connection between mine cars so that the mine car bolt cannot drop off by itself. And the bolt anti-falling ring is welded above the mine car bolt hole to lock the mine car bolt. The bolt anticreep circle material is mostly cast iron, and the cast iron has good wearability and cutting nature. The anti-drop ring of the plug pin in the daily operation of the mine car can only realize the upper side locking, and can only effectively prevent the phenomenon that the plug pin jumps out in the operation of the mine car. However, when the mine car is turned over in the turning-over device, the phenomenon that the bolt falls off often occurs, and great potential safety hazards are caused. Under the background, the invention provides the bolt with the locking function, so that the use of the bolt anti-falling ring can be omitted, and the aim of locking the upper side and the lower side of the bolt can be fulfilled. The bolt is simple in structure, easy to process, safe, reliable and cost-saving.
Disclosure of Invention
The utility model aims at providing a from mine car bolt of taking blocking device solves the problem that the mine car bolt drops easily in the transportation among the prior art.
In order to realize the purpose, the technical scheme of the utility model is that:
the utility model provides a from mine car bolt of taking blocking device, includes cylindrical bolt body, spacing groove, spout have been seted up to bolt body bottom, the bolt body is run through at the spacing groove both ends, the spacing inslot rotation is connected with the locking board, the locking board includes circular-arc turning block and stopper, stopper one side and turning block fixed connection, integrated into one piece has spacing hook on the turning block, the spout is seted up at the spacing groove top, and spout axis and the coaxial setting of bolt body axis, be equipped with spring, ejector pin in the spout, spring one end fixed connection is on the spout inner wall, spring other end fixed connection is on the ejector pin, ejector pin bottom and locking board looks butt.
Furthermore, the bottom of the ejector rod is arc-shaped and is abutted against the rotating block.
Furthermore, the fixed chain is connected with the pivot between the spacing inslot wall, the turning block rotates to be connected in the pivot.
Furthermore, the outer side of the rotating shaft is wrapped with an elastic damping material.
Compared with the prior art, the utility model has the advantages and positive effect be:
the device consists of a locking plate, a rotating shaft, an ejector rod and a spring; the locking function of the bolt is realized by shifting the locking plate in the locking mechanism, the locking plate is simple to operate, the locking function can be realized, and the bolt can be conveniently picked; when the device is connected with a mine, a bolt handle can be welded at the top of the device, so that the bolt can be conveniently picked; when the device is used in the flat car, the handles can not be welded, the flatness of the panel of the flat car can be kept, the device can prevent the occurrence of the phenomenon that the bolt falls off when the mine car is overturned in the overturning device, and the potential safety hazard is reduced.
Drawings
