Definitions
- the resulting spring force acts on the pressure wedge on the brake wedge and determines the occurring between the latter and the guide bar Normal force and thus the resulting, acting as a braking force on the load-carrying friction force.
- Such safety gears have the disadvantage that the force acting on the brake wedge normal force, regardless of different payloads in the load handling device and other influences, such as the condition and contamination of the braking surfaces, the current speed and the ambient temperature, is always the same size. As a result, greatly different deceleration values occur on the load-bearing device in the event of a catch. Since a certain minimum delay must be guaranteed for safety reasons, delay values above the permissible limit value often result with minimum payload.
- the piston rod 19 the cylinder chamber 18 facing away from the cylinder chamber is connected via a flow control valve 20 and a control valve 21 with a hydraulic medium container 22, wherein these compounds can be designed as pressure-resistant piping or as connections within a hydraulic block.
- the flow control valve 20 is designed as a blast valve or flow control valve with check valve and has the task to influence the outflow of the hydraulic medium from the hydraulic cylinder 18 so that the brake wedge 13 is pulled in the event of a catch at a controlled speed in the narrowing gap, so that the on Lifting device 2 occurring jerk is reduced at the start of braking.
- An embodiment of the flow control valve 20 as a flow control valve has the advantage that the flow of the hydraulic medium is kept constant regardless of the pressure conditions.
- this process produces a braking force proportional to the penetration depth of the brake wedge 13 and acting on the load receiving means 2.
- the delay of the load receiving means 2 reaches a certain value
- the set to this value delay sensor 23 reacts by the inertial force of the weight body 24 via the angle lever 25, the control valve 21 against the spring 28 in the locked state. This will further penetration of the brake wedge 13 and an undesirably high delay of Lifting device 2 prevented.
- the deceleration sensor 23 would release the flow through the control valve 21 again and allow for a deeper penetration of the brake wedge until the set deceleration value is reached again.

Claims (12)
- Parachute dont la force de freinage est fonction de la décélération pour un dispositif de suspension de la charge d'un ascenseur, qui est déclenché par un limiteur de vitesse (6) de l'ascenseur en cas de vitesse excessive du dispositif de suspension, au moins un coin de freinage (13) pénétrant dans un interstice qui va en rétrécissant, entre un corps de pression (14) du parachute qui est supporté élastiquement et une glissière (1) du dispositif de suspension, et produisant ainsi une force de freinage, et l'intensité de cette force de freinage étant fonction de la décélération qui apparaît au niveau du dispositif de suspension de la charge,
caractérisé en ce qu'il comporte un limiteur de course (18, 18.1) qui limite la course de pénétration du ou des coins de freinage (13) en fonction de la décélération du dispositif de suspension de la charge (2). - Parachute selon la revendication 1, caractérisé en ce qu'il comporte un limiteur de vitesse qui définit de manière réglable la vitesse du coin de freinage (13) pendant sa course de pénétration.
- Parachute selon la revendication 1, caractérisé en ce que le limiteur de course qui limite la course de pénétration du coin de freinage (13) en fonction de la décélération du dispositif de suspension de la charge (2) est constitué par un système hydraulique influencé par un capteur de décélération (23).
