Description

The invention relates to climbing and industrial mountaineering, can be used for lowering or climbing a climber, as well as for tensioning chain hoists.

The most famous device for descent is the EIGHT [1], which consists of two rings, inextricably linked, while one ring is one and a half times smaller than the other with a diameter of the inner circle of up to 50 mm

The eight has a number of drawbacks, namely, during the descent, the rope is twisted, and when stopping, it is quite difficult to fix the free end of the rope.

To solve the problem of fixing the free end of the rope, use the EGG WITH HORNS [1], which, unlike the classical figure eight, on the side of the large ring contains a pair of horns that are interconnected and attached to the leg, inextricably linked to the large ring.

The main drawback of the figure eight with horns is also the twisting of the free end of the rope.

The GRI-GRI trigger device [2] is also known, which contains a housing inside which a flywheel with an eccentric is placed, while the flywheel is connected to a lever.

In the gri-gr device, the rope goes around a round flywheel with an eccentric. Under load, the rope rotates the flywheel around its axis, which presses it against the body of the device and blocks the descent. The angle of rotation of the lever can control the speed of etching the rope through the device, as well as unlock it.

The gri-gr device is automatically locked under load and does not twist the rope, but during operation it is difficult to descend on a dirty rope, and it is also impossible to descend on a double rope.

The prior art there are many modifications of the RUNNING DEVICES [3], which consist of two pulleys enclosed in a frame of two plates, while one of the plates is made rotatable around the axis of one of the pulleys for refueling the rope. In the closed position, the rotary plate is fixed with a latch.

To increase the safety and ease of descent, DESANTERS [3] are used, which, unlike the above-mentioned launching devices, are equipped with a control and unlocking handle, which can be used to control the friction of the rope.

The main disadvantages of the landing party are the inability to work with two ropes, the inability to remove the rope without the use of additional clamps, and the inability to use when lifting.

The closest in technical essence is CLAMP [4], which contains a hollow all-metal body with free ends, a partially open base and one rib, in which a hole is made in the upper part of the body for fixing the axis of the clamping device (cam) with notches. An opening for a carbine is made in the upper part of the casing, and an opening for the foot pedal is made in the lower part of the casing.

The disadvantages of the prototype are the inability to use with two ropes, structural limitations of use only for lifting, as well as the lack of ability to control the friction of the rope.

The purpose of the invention is to ensure the versatility of using one device for lowering and lifting.

The technical result consists in providing the ability to work with two ropes, providing the ability to control the friction force, provides easy removal from tensioned ropes.

The technical result is achieved due to the fact that the claimed climbing method, in which they use a climbing device for climbing, comprising an all-metal body with free ends and a hole for the fastener, a handle, a friction fork, and also a clamping device with notches, characterized in that on one a small slot is made to the side rib of the body, and a continuous slot is made along the other side rib, which form a pair of flanges with recesses; on the opposite side of the handle relative to the friction fork perform a ring with a pair of holes; before starting the descent, on the upper platform, one or two ropes are drawn into the inner surface of the housing through a continuous slot and placed respectively between the clamping device and the recesses in the flanges, as well as between the hole for the fastener and the flanges; then by means of a clamping device with notches, the ropes are pressed to the recess and the flanges; before climbing into the holes at the ring, they pass one carabiner that connects to the suspension system, then install the second same device or standard clamp on the main rope, which connects to the footboard; to climb up, either insert the toe of the boot into the step, straighten the leg and move the lower device up the rope, then weaken the leg, move the upper device up the rope; or use only one device for lifting, using instead of the footboard the ropes extending from the bottom of the device.

For reliable fixation of the device on the rope, the free ends of the ropes are pushed into the loop of the ropes through the ring and looped over the top of the ring. To reduce the frictional force and the descent, squeeze the notches from the ropes.

The implementation of the invention

The method can be implemented using a device that consists of an all-metal casing 1 with extension 2 at the bottom. The ends 2 and 3 of the housing 1 are made open. Along the expansion 2, a small slot 4 is made on one of the ribs of the housing 1, and a continuous slot 5 is made along the opposite rib. The solid slot forms a pair of flanges 6 on which a recess 7 is made. In the lower part of the housing 1, a hole 8 is made for the fastener 9, which equipped with a protective cylinder 10. Also, a hole 11 is made in the housing 1 for the fastening element 12, which is equipped with a spring 13 and is the axis of attachment of the handle 14.

The handle 14 consists of a friction fork 15 with a pair of horns 16, in the middle part contains an opening 17 for engagement with a spring, an opening 18 for the fastener 12 and an opening for the clamping device 19 with notches 20. On the opposite side of the handle 14 relative to the friction fork 15 is oval ring 21 with a pair of holes 22.

Holes 22 are designed to attach the device to the climber's suspension system. The upper parts of the housing 1 and the rings 21 are provided with a protective coating 23

The device operates as follows.

Before starting the descent on the upper platform, the climber passes through the slot 5 one or two ropes 24 (in Fig. 6) into the inner surface of the housing 1 and places them respectively between the clamping device 19 and the recesses 7 in the flanges 6, as well as between the protective cylinder 10 and the flanges 6. The spring 13 with the device 19 and the notches 20 presses the ropes 24 to the recess 7 and the flanges 6. After loading the ropes 24, the notches 20 securely hold the climber. To reduce friction and descent, the climber in the direction of the arrow in FIG. 6 presses the ring 21, which presses the notches 20 from the ropes 24.

Before climbing (Fig. 5), the climber throws one carbine 25 through the holes 22, which connects to the suspension system. Above the device, on the main rope 24, a second same device or standard clamp is installed, which connects to the footboard. To climb up, the climber inserts the toe of the boot into the footboard, straightens the leg and moves the lower device along the rope 24 up, then loosens the leg and moves the upper device up the rope 24. Also, for lifting, you can use only one device, using instead of the footboard the ropes extending from the bottom of the device.

To securely fix the device to the rope, the free ends of the ropes 24 the climber pushes the loop of the ropes 24 through the ring 21 and throws a loop on the top of the ring.

In FIG. 7 shows the working position of the climber's hand when using the device.

The design of the device allows you to use it as a standard clamp when pulling the chain hoist and provides easy removal of the device from the tensioned ropes.

In 2014, the applicant made a prototype (see Fig. 8) of the hoisting device and conducted its tests, which confirmed the achieved technical result and positive technical effects, which consist in the fact that:

- it is possible to use the device for lowering or lifting,

as well as for insurance and self-insurance,

- it is possible to use the device as a clamp when pulling the chain hoist,

- provides the ability to simultaneously work with two ropes.

Tests also confirmed the high reliability and safety of operation of the device.
