Definitions

  • the invention relates to rescue equipment and can be used for evacuation from high-rise buildings using a rope of people and goods.
  • the use of the claimed device is also possible with the work of installers, in mountain climbing and speleology.
  • Known trigger device containing a block section for passing the rope, equipped with a base and a cover, as well as mounted on the base equipped with a handle movable brake element and guide rollers, (a.p. CPCP JYa 1144710, IPC A 63 V 29/02, publ. 15.03 .1985).
  • the brake element is made in the form of a spring-loaded roller equipped with a handle. The descent of a person is carried out by pressing and holding down the handle associated with the spring-loaded roller. In the absence of effort on the part of a person, a spring-loaded roller clamps it under the influence of a loaded rope, thereby braking.
  • the closest analogue of the claimed device is a known launching device containing a block section for passing the rope, equipped with a base with a hole for attaching a carbine and a cover, a friction roller mounted on the base, and a brake element equipped with a handle and pivotally connected to the base (see Technical PETZL company manual for the STOP D09 product, publ. 1991).
  • the brake element is made in the form of a movable cam equipped with a handle.
  • the device cover is mounted on the same axis with the brake element and is made to rotate around its axis. Laying the rope and attaching the carabiner to the device is done with the lid open, then the lid closes. In the closed position, the lid is held by a latch.
  • the descent of a person is carried out by pressing and holding down the handle associated with the movable cam. If there is no effort on the part of a person, the cam of the brake element under the action of a loaded rope rotates and carries out jamming of the rope, which leads to the cessation of descent.
  • a disadvantage of the known device is the small area of the working surface of the brake element, which with a sharp dynamic load (sudden braking) can lead to a "bite" of the rope with the cam of the brake element and create an emergency situation that could cause a person to fall.
  • Placing the latch opposite to the handle of the brake element causes the inexperienced user to push the latch to the open position with his fingers, which, when the load on the device is removed (for example, a person rests his feet on the curtain rod), can lead to self-opening of the cover device and the loss of the rope from it.
  • the known device has insufficient functionality due to the presence of only one hole for securing a carbine, which is manifested in the inability to use the device as a fixed unit without the use of additional devices.
  • Another disadvantage of the known device is the inability to limit the maximum speed of descent, which, if necessary, the descent of a cargo of large mass makes it difficult to use the device.
  • the objective of the invention is to increase the safety of the descent and expand the functionality of the trigger device.
  • the problem is achieved in that in the known trigger device containing at least one block section for passing the rope, equipped with a base with a hole for attaching a carbine and a cover, a friction roller mounted on the base, and a brake element equipped with a handle and pivotally connected to the base according to the invention, at least one additional friction roller and a friction cam pivotally connected to the base are installed on the base, the front working surface of which facing the brake element has a curved profile corresponding to the profile of the working surface of the brake element and it is equidistant to it, forming a stream for laying the rope, while the length of the stream is selected in accordance with the following dependence:
  • the trigger device can be equipped with an additional friction element pivotally connected to the base, the working surface of which has a curved profile corresponding to the profile of the rear working surface of the friction cam and is equidistant to it, forming an additional stream for laying the rope, while the length of the additional stream is selected in accordance with the following dependence : where: D is the diameter of the rope, mm;
  • At least one additional hole for attaching a carbine can be made at the base of the trigger device.
  • the technical result of the invention is to increase the safety of man descent by eliminating the possibility of "biting" the rope as a result of sudden braking, which is achieved by increasing the contact area of the rope with the working surfaces of the friction cam and the brake element, forming a rope for laying the rope, the length of which is determined based on the indicated dependence :
  • the descent of a person is carried out when installed in the middle position of the handle associated with the brake element. Further descent with a constant pre-selected speed can take place without human intervention. At the same time, it is possible to stop the descent by pulling a portion of the rope below the trigger device.
  • the functionality of the inventive device is enhanced by the installation of additional friction rollers and an additional friction element, which allows for various styling of the rope, thereby choosing the maximum or minimum speed of the descent of a person (or load) depending on its weight, physical fitness, operating experience of the inventive device.
