Description

The invention relates to devices for lifting trolleys from one rail level to another, more than rjb cojq-; H, and can be used mainly in the coal and mining npON-fbJU -.

penno x.

It is known a trap device for stopping a vehicle, roads at higher than a predetermined speed, comprising a housing with a stabilizing roller mounted on it with a roller-sensor, which burns the wall of the rail, swivels the ex. centric, wedged between the wall of the monorail and the device body.

However, this device does not provide smooth brakes, trolleys.

A height compensator is known, containing: “a frame with track rails and catches in the form of yokes” (one of which interacts with the wheel of the trolley and the other with a return spring and an emphasis) Catchers are installed in pairs with a certain interval along the entire length of the rail gugti . When pulling the carriage by tractional authority, the last of their own wheels of the

Such a height compensator does not provide a reliable catch of trolleys when it comes down to a traction body, since if they are hard-hit, they may be thrown off a railroad car.

The aim of the invention {ip is to ensure smooth braking of the captured wag-nets in order to obtain the necessary braking force.

It is possible that it is compensated by two brakes of a cable and supporting them from hanging up of the bracket, akreple1) to the soles of the rails with a longitudinal movement,

These are the catchers mounted on brackets. in their short shoulders in contact with the cannabis. In addition, the brackets are made with pro-tricky creeks to peppy brake cables and stops to restrict the turn of the turners. On 4ig. 1 shows a side view of the comPeisator described in FIG. 2 - section А-А on fkgL- on «Jsir. 3 - section BB on fng.2. The compensator consists of the drive 1, the frame 2 with the track rails, the tension station 3 and the traction element 4. The frame 2 is equipped with two brake ropes 5 with spring-loaded tensioning devices that provide constant tension for the ropes, and when trapping and braking the tension ropes to form a loop. To the soles of the rails 6, the brackets 7 are suspended with the possibility of longitudinal movement, supporting the brake cables 5 from sagging. On axis 8 of the brackets 7, catchers 9 are installed, held in the initial operating position by springs U torsion. At the same time, short seals of catchers 9 are in contact with chga 5 brake cable. Brackets 7 are made with profile strands to form a loop of brake cables and stops 11 on rotation of catchers 9. When pulled by trolleys of trolleys, the latter run over the large shoulder with a rim catcher 9, which, twisting the horn 10, deviates in the direction of movement of the trolley. When the wheel rim comes off the catcher, the latter returns to its original position under the action of a spring. When rolling the trolley (when the traction body breaks, the power is turned off, and so on, the wheel sets rest against catchers 9. Under the influence of the weight of the trolley and their inertia forces, catchers turn around axis 8 from the initial working position to the catch position. Short shoulders, interacting with brake ka

; Article 5, cause their bending in the arm brackets s 7. As the trainers deviate from the working (initial) application, they will bend the brake hantov 5, and consequently, a variable braking assis- tance of the arm with the catches of the square meter is created. The extreme position of the fluntel, which corresponds to the maximum angle n, is a rope. the maximum braking force is limited by the stop 11. The catchers 9 move with the brackets 7 along the rail soles until the trolley speed is completely quenched, i.e. her stop. The braking system is reset to its initial position after removing the load on catchers from the trolley and placing them in the initial position e. Claim 1. The height compensator including the frame with track rails and the rocker arms catches are distinguished by the fact that to ensure smooth braking of the caught wagzstocks, it is equipped with two brake cables and subframes from sagging with matte attached to the rail soles with the possibility of longitudinal p & relocated, with catchers installed on the brackets, and their short shoulders in contact with the ropes. 2. A compensator in accordance with claim 1, wherein the brackets are made with a profile in order to form a loop of brake cables in order to obtain the necessary braking force. 3. The compensator in paragraphs. 1 and 2, characterized in that the brackets are provided with stops to limit the rotation of the catchers.
