Abstract
The utility model relates to a small-sized cage and trolley anti-dropping safety device, which belongs to a mine hoisting device. The small-sized cage and trolley anti-dropping safety device makes use of an anti-dropping wheel and a trapezoidal groove as critical components. The anti-dropping wheel is supported by a spring and can move up and down along a guide rail; the outer side of the rim of anti-dropping wheel is made into a slope; the anti-dropping wheel is hung and wound by a safety steel cable; the two ends if the safety steel cable are respectively connected with the original hoisting container; The lower end of the anti-dropping wheel is provided with the trapezoidal groove; the inner side of the trapezoidal groove is made into a slope and is inserted with a friction pad. Once the hoisting steel cable is broken, the hoisting container compresses and supports the spring through the safety steel and the anti-dropping wheel to make the anti-dropping wheel move down to the inner side of the trapezoidal groove. Then, the trapezoidal groove generates the friction braking action for the anti-dropping wheel and the hoisting container stop falling. The utility model has the advantages of reliable and smooth braking process and simple structure and processing technique.
Description
Name of the present utility model is called small canister cage and skip bucket anti-dropping safety device.
The utility model belongs to mine hoist equipment.
Small mine adopts 0.5T or non-standard cage more at present, and most do not have disconnected rope anti-dropping safety device, and the main shaft skip bucket does not all have anti-fall device.In case hoisting cable is disrumpent feelings, lifting container will directly weigh down the shaft bottom, certainly will lead to the personnel death, the great serious accident of device damage.Indivedual small-sized cages that anti-fall device has been installed, anti-fall wheel rim is made two toothrow circles, hangs around the safety steel rope between the two toothrow circles.Glancing impact is moved down by anti-fall wheel of spring-loaded, and with relatively-stationary tooth bar engagement, thereby the rotation that stops gear ring is to reach the purpose that prevents that lifting container from falling.This brake mode lacks necessary buffering course, take place easily to beat the tooth phenomenon, and the making of gear ring tooth bar processing is rather difficult, and is also high to the requirement of raw MAT'L itself.
The purpose of this utility model is to provide a kind of later-model anti-dropping safety device, to eliminate the weak point of existing apparatus.
Structure of the present utility model and principle of work are as follows: the anti-fall wheel used spring-loaded, is installed on the sheave wheel platform, and 15 ° to 20 ° inclined-plane is made in the wheel rim outside.A safe steel rope is hung around anti-fall the wheel, and the two ends of rope connect two original lifting containers respectively.A buffering dovetail groove is established in the anti-fall below of taking turns, and the groove inboard is also made 15 ° to 20 ° inclined-plane and studded with friction lining.In case hoisting cable is disrumpent feelings, safe steel rope just begins to play a role.At this moment, container dead weight and load act on anti-fall the wheel by the safety steel rope, the compression support spring makes anti-fall the wheel move down and insert in the dovetail groove, anti-fall take turns and groove internal friction liner between friction force will cushion and brake rotating anti-fall and take turns, container is stopped falling reposefully.
The utlity model has tangible technique effect: one, the anti-fall structure of taking turns and cushion dovetail groove and make all simplyr, and easy for installation, cost is low; Its two, can calculate cushion effect exactly, the buffer deceleration degree and the buffering distance, the buffer deceleration degree is little, braking procedure is steady.
Description of drawings:
Figure one: small-sized cage and skip bucket anti-dropping safety device front elevation.
Figure two: small-sized cage and skip bucket anti-dropping safety device left view.
Sequence number among the figure: 1--is anti-fall to take turns; The 2--wheel shaft; 3--takes turns journal box body; The 4--support spring; The 5--spring bearing; 6--cushions dovetail groove; 7--wheel journal box body guide rail; The 8--gusset; The 9--connecting panel.
Below in conjunction with accompanying drawing, small-sized cage and skip bucket anti-dropping safety device are described further: anti-fallly take turns 1 and be fixed on the wheel shaft 2, wheel shaft 2 stretches in the wheel journal box body 3, wheel journal box body 3 is bearing on the spring 4, spring 4 bottoms are fixed on the bearing 5, and wheel journal box body 3 can slide up and down along guide rail 7.A buffering dovetail groove 6 is installed in the anti-fall below of taking turns, after hoisting cable is disrumpent feelings, under the action of gravity of container and load, the anti-fall 1 compression support spring 4 and moving down of taking turns, wheel rim inserts in the buffering dovetail groove 6 and produces friction buffer power, thereby reaches anti-fall purpose.The effect of gusset 8 is a rigidity of strengthening guide rail 7, and the effect of connecting panel 9 is that the guide rail 7 of wheel journal box body 3 both sides is connected together.
Claims (1)
- A kind of anti-dropping safety device that is used for small-sized cage and skip bucket is by the anti-fall critical component of taking turns and cushion dovetail groove as this device that is installed on the sheave wheel platform.The anti-fall wheel by spring-loaded also can move up and down along guide rail, hangs around a safe steel rope on the wheel, and the two ends of rope link to each other with original two lifting containers respectively.This device is characterised in that: 15 ° to 20 ° inclined-plane is made in the anti-fall wheel rim outside, and a buffering dovetail groove is established in the anti-fall below of taking turns, and studs with friction lining on the inclined-plane in the groove, and the angle of inclination, inclined-plane is consistent with angle of inclination, inclined-plane, the anti-fall wheel rim outside in the groove.
