Abstract

The utility model relates to a mine car arrester for an incline shaft, comprising a box cover with a flat plate and a car arrester plate which is assembled on the box cover, wherein, the drive rocker bar and the driven rocker bar of a four-bar mechanism are hinged at two ends of a sliver pedal plate. The driven rocker bar is fixed on one end of a rotary shaft whose the other end is fixed with the car arrester plate which is turned synchronically with the driven rocker bar. The utility model has the advantages of simple structure, easy operation, sensitive and reliable use, no energy consumption and safe self-locking, and prevents effectively the accident of the mine car dropping a shaft from happening.

Description

Mine car arrester for incline shaft

The utility model relates to the safe self-locking protector that a kind of slope is used, particularly a kind of inclined shaft car arrester.

At present, the slope mouth during the mine transportation is produced except that safety door is set, also should be provided with the safe self-locking protector for the sake of security.Existing inclined shaft car arrester device seldom.The inclined shaft that has adopts the simple and easy piece of holding up traffic that rides on the light rail.This piece of holding up traffic is operated by hand, promptly ought open the piece of holding up traffic and leave light rail, and mine car just passes through, and the piece of holding up traffic again closes after car is walked.But, sometimes mine car by after forget the piece of holding up traffic that closes, then mine car weighs down well just break safety door easily under effect of inertia after.Sometimes the heavy mine car that inertia is too big also can be crossed this simple and easy piece of holding up traffic, and causes heavy economic losses.Therefore,, must eliminate the hidden danger that causes the sport car falling accident, safe and reliable car arrester is provided for doing the safe operation of inclined shaft transportation system well.

The purpose of this utility model provides a kind of improved inclined shaft car arrester, and its features simple structure, operation easily use sensitivity reliable, the source of not consuming energy, and safe self-locking can prevent effectively that the sport car falling accident from taking place.

The purpose of this utility model is achieved in that this device comprises and has dull and stereotyped case cover and assemble the plate of holding up traffic on it, wherein drive crank in the quadric chain and driven rocking bar are hinged on rectangular foot rest two ends, driven rocking bar is packed in rotating shaft one end, and the rotating shaft other end is fixed with the plate of holding up traffic that can rotate synchronously with driven rocking bar.

Because the utility model adopts the rectangular foot rest that is hinged on drive crank and the driven rocking bar, and the driven rocking bar that is packed in the same rotating shaft rotates synchronously with the plate of holding up traffic, so when stepping foot rest, drive the plate of holding up traffic when driven rocking bar rotates rotates thereupon, when the plate of holding up traffic fell down to enter between the light rail, mine car could pass through, otherwise the plate of keeping off a car is when upright, mine car in the time of can blocking sport car avoids the mine car falling accident to take place effectively.Because of it relies on machine driving fully, thus features simple structure, operation easily, safe and reliable self-locking can be realized in the source of not consuming energy.Therefore this device is very easily applied.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a kind of concrete structure upward view of the present utility model.

Fig. 2 is the sectional view of Fig. 1.

Describe concrete structure of the present utility model in detail according to Fig. 1-2.This device comprises case cover 8, dull and stereotyped 7, light rail 1, foot rest 10, the rotating shaft 4 by bearing support 3 assemblings and is packed in parts such as the plate 6 of holding up traffic in the rotating shaft 4.Wherein drive crank in the quadric chain 11 and driven rocking bar 9 are hinged on the two ends of strip foot rest 10.Driven rocking bar 9 is packed in an end of rotating shaft 4.Being packed in rotating shaft 4 other ends can stand in the middle of two light rails with the upper end of the driven rocking bar 9 synchronous plates 6 of holding up traffic that rotate.Its lower end is provided with limiting plate 5, and can limit the plate 6 of holding up traffic can only clockwise rotate.Rotating shaft 4 also is provided with and can makes the plate 6 automatically reset counterweights 2 of holding up traffic.

Transferring to inclined shaft in mine car (right-to-left) operation, the signalman is in the go-cart of mine car side, will be when holding up traffic plate 6 when the mine car front-wheel, and signalman's a pin is just in time stepped on the foot rest 10 of car arrester.Foot rest drives driven rocking bar 9 and rotates, and makes the plate 6 of holding up traffic also rotate thereupon, and when being lower than mine car axle (shown in Fig. 2 double dot dash line), mine car is gone into well by car arrester smoothly.After mine car pushed away car arrester, hold up traffic plate 6 under the effect of counterweight 2 and limiting plate 5, still recover reset condition, thereby reach the interlock protection effect.When from giraffe, mine car axle pressure drag sweep 6 easily clockwise rotates, and mine car passes through smoothly.

Claims

1, a kind of inclined shaft car arrester, comprise and have dull and stereotyped case cover and assemble the plate of holding up traffic on it, it is characterized in that drive crank and driven rocking bar in the quadric chain are hinged on rectangular foot rest two ends, driven rocking bar is packed in rotating shaft one end, and the rotating shaft other end is fixed with the plate of holding up traffic that can rotate synchronously with driven rocking bar.

2, car arrester according to claim 1 is characterized in that setting makes the automatically reset counterweight of the plate of holding up traffic in rotating shaft.
