Detailed Description

In order to more clearly illustrate the present invention, the present invention is further described below with reference to preferred embodiments and the accompanying drawings.

As shown in fig. 1 and 2, the anti-drop pin for mine cars used for transportation in mine inclined shafts comprises an arc-shaped lifting handle 1, a pressure rod 2, an anti-drop safety hook 3, a main pin 4, a baffle plate 5, a supporting plate 6, a stop pin 7, an anti-drop safety hook pin 8 and a pressure rod pin shaft 9.

The arc lifting handle 1 is an operation handle part for workers to lift or insert the anti-unhooking pin of the mine car, the arc lifting handle 1 is welded on the baffle 5, and the arc lifting handle 1 is formed by round steel with the diameter of 12 mm;

the pressure rod 2 is mainly used for opening the anti-drop safety hook 3 under the action of the pressure rod 2 so as to be convenient for plugging and unplugging the anti-drop pin of the mine car, the pressure rod 2 is fixed at the upper end of the supporting plate 6 through a pressure rod pin shaft 9, the number of the support plates 6 is two, two ends of the pressure rod pin shaft 9 are respectively connected with the two support plates 6, the pressure rod 2 can freely rotate around the pressure rod pin shaft 9, the pressure rod 2 obtains action pressure by manually holding the arc-shaped lifting handle 1 and the upper part of the pressure rod 2 by a worker, so that the upper part of the pressure rod 2 is stressed, the pressure rod 2 rotates around the pressure rod pin shaft 9, on 2 lower parts of pressure pole transmit the power for the backing pin 7 that is located 3 upper portions of anticreep safety hook, backing pin 7 transmits the power for 3 upper portions of anticreep safety hook, and 3 upper portions of anticreep safety hook atress are rotatory around anticreep safety hook round pin axle 8 for the lower part of anticreep safety hook 3 opens.

The anti-drop safety hook 3 is mainly used for automatically clamping a mine car on a mine car collision counterweight pulling plate 10 under the action of gravity after the mine car is inserted into the mine car anti-drop pin, the mine car collision counterweight pulling plate 10 is a mine car part, and the mine car anti-drop pin cannot automatically drop out of a pin hole of the mine car collision counterweight pulling plate 10 due to bumping when the mine car runs; anticreep safety hook 3 comprises two hook type spares, the hook type spare is made by 12mm steel plate, the first half of two hook type spares is in the same place through backing pin 7 welding, anticreep safety hook 3 is fixed in backup pad 6 through anticreep safety hook round pin axle 8, anticreep safety hook round pin axle 8's both ends are connected with the well middle-upper position of two backup pads 6 respectively, anticreep safety hook 3 can be around anticreep safety hook round pin axle 8 free rotation, pressure bar 2 obtains the effect pressure and carries handle 1 and pressure bar 2 upper portion through the manpower gripping arc, make pressure bar 2 upper portion atress, pressure bar 2 is rotatory around pressure bar round pin axle 9, pressure bar 2 lower part transmits the effort to on the backing pin 7 that is located upper portion, anticreep safety hook 3 upper portion atress, anticreep safety hook 3 is rotatory around anticreep safety hook round pin axle 8, two hook type spare lower parts keep away from each other, thereby anticreep safety hook 3 lower part opens, effort disappearance anticreep The rotary automatic clamping device is automatically clamped on the mine car collision counterweight pulling plate 10 instead of being returned by a spring, and the spring return has certain risks, such as the spring reaches the fatigue limit or the spring is broken, and the anti-falling safety hook is easy to open, so that the pin string is led out of the pin hole.

The main pin 4 is mainly used for connecting a steel wire rope hook head ring of the hoisting machine with a mine car, and the main pin 4 is welded on the lower surface of the baffle 5;

the supporting plate 6 is welded on the upper surface of the baffle 5;

the main function of the baffle 5 is to prevent the anti-unhooking pin of the mine car from slipping into the bolt hole of the counterweight pulling plate 10 of the collision head of the mine car, and the anti-unhooking pin of the mine car is inserted into the bolt hole on the counterweight pulling plate 10 of the collision head of the mine car to be operated normally, while the main function of the baffle 5 is to prevent the anti-unhooking pin of the mine car from slipping into the bolt hole of the counterweight pulling plate of the collision head of the mine car, so that the anti-unhooking pin of the mine car is protected, if the baffle 5 is not arranged, the support plate 6 will fall into the bolt hole of the counterweight pulling plate 10 of the collision head of the mine car.

The support plate 6 is mainly used for fixing the anti-falling safety hook pin shaft 8 and the pressure rod pin shaft 9, and the support plate 6, the baffle 5 and the main pin 4 are connected into a whole.

The implementation operation is as follows: when the mine inclined shaft is transported, a worker inserts the three-ring chain of the steel wire rope of the elevator into the collision head of the mine car, at the moment, the worker lifts the mine car and the anti-disengaging pin of the three-ring chain of the steel wire rope of the elevator, in the process, the worker holds the arc lifting handle 1 and simultaneously gives acting force to the pressure rod 2, the pressure rod 2 is pressed away from the anti-disengaging safety hook 3 after being subjected to the acting force, the anti-disengaging safety hook 3 is opened under the acting force of the pressure rod 2 (detailed view is shown in figure 1), the worker inserts the anti-disengaging pin of the mine car into the chain of the collision head of the mine car and the three-ring chain, and at the same time, after the worker loosens the pressure rod 2, the anti-disengaging safety hook 3 automatically falls to the counterweight pull plate 10 of the collision head. Use through practice many times the utility model provides a mine inclined shaft mine car mousing-hook pin does not have the sign of any unhook, but the wide application is in the inclined shaft transportation of mine car.
