Description

one

The invention relates to equipment for mine cargo and passenger conveyors and is intended to increase the stability of passengers after their departure from the conveyor; at destinations and transplants.

It is known a device other descent from the conveyor, including directions and covering their movable elastic handrail with a drive j 1J.

This device is equipped with a drive, which damages the vanishing point and complicates the design of the handrail. In addition, when transferring the handrail to a new place, there it is necessary to connect the power supply line of the drive, which causes a significant amount of additional installation work under conditions.

The closest technical sutannoy to the proposed is a point of departure from the mine cargo and passenger fan, including a movable handrail. and spring-loaded derailment area 2.

The disadvantage of it is low security.

The purpose of the invention is to increase the safety of the vanishing point.

The goal is achieved by the fact that the point of departure from the mine freight. Zhirsky conveyor, which includes the sub-rail handrail and the spring-loaded landing area, is equipped with a braking mechanism, made in the form of a brake shoe and installed with a pulley attached to the spring-loaded release platform.

FIG. 1 shows the vanishing point, general view; in fig. 2 shows section A-A in FIG. one.

On a fixed base 1 sharnarnn. However, the platform 3, which relies on the spring 2, is fixed to the brake pulley 4, pressed against the brake shoe 5.

Adjacent to the pulley 4 with a gap, a guide 7 mounted on the crankshafts 6 is attached, covered together with the pulley 4 by a closed loop 8 of an o-shaped cross section made of an elastic material, for example, rubber with fabric pads.

The parameters of the handrail are chosen in such a way that the pulley 4 is retracted from the shoe 5 under the influence of the weight of the passenger who pulled the platform 3, and the deceleration of the loop 8 was equal to the passenger's distance.

The device works as follows.

After the descent from the conveyor, the passenger steps onto the descent platform 3 and, resting his feet on it, grabs the upper arm of the loop 8 with his outstretched hand, getting an additional stop at the pickup point to maintain his balance and slow down movement. Under the influence of the weight of the 5 soot, the spring 2 is compressed, the landing platform 3 rotates and the pulley 4 moves away from the shoe 5, releasing the loop 8. In this position, the resistance to movement of the loop 8 M1 and the passenger moving by inertia around the landing platform 3 the upper branch of loop 8 easily accelerates to its own speed. At the same time, the passenger himself receives an additional slowdown and, approaching his torso to the point where the loops 8 are gripped, and how much he bends the arm at the elbow joint. At the time of equalizing the speeds of loop 8 and the passenger, the latter passes from the descent platform 3 to the stationary base 1. Under the action of the weight released the passenger of the spring 2, the 3-stroke platform returns to its original position, the pulley 4 presses against the shoe 5, the resistance to movement of the loop 8 becomes greater than the pushing force exerted on it from the passenger's hand, and its speed decreases . With the given parameters, handrail, and forces acting on the loop 8, its deceleration is the same as that of the passenger. As a result, the position of the grip area of the loop 8 remains almost unchanged relative to the passenger and is used as a stop to maintain balance and additional braking. In case of a mg increase in the sagging effect m loop 8, the pulley 4 is depressed on the shoe 5 and the resistance to movement of the loop 8. In this case, its speed kills slower than the speed

the passenger. As a result, the grip area of the loop -b is removed from the passenger’s torso and it can no longer affect the loop 8 with increased flexibility. On the contrary, in case of an accidental decrease in the number of scientific research institutes of force action on the loop 8, pressing the pulley 4 on the shoe 5 increases and the resistance to movement of the loop 8 increases. Its speed in this case will decrease faster than the speed of the pass sire. As a result, the passenger arrives at the body to the hinge 8 and, moving along inerts, does not involuntarily increase the force effect on the hinge 8. Thus, reliable balance and intense braking of the passenger after descent from the conveyor are provided without a stationary drive in the design of the handrail, which greatly simplifies its operation in conditions of frequent transfer of derailment sites along the length of the conveyor following the advancement of the slab serviced by this conveyor, since this eliminates the additional Remedial work necessary for building up the power supply lines of the drive, dismantling it and then connecting it, as well as improving the safety of the gathering. The formula was invented by the Point of Departure from the mine cargo-and-passenger conveyor, including a movable handrail and a spring-loaded derailment platform, characterized in that, in order to increase the safety of the point of derailment, it is equipped with a brake mechanism made in the form of a brake shoe and installed with an interoperable pulley; fixed on the spring platform of the gathering.
