Abstract

This invention relates to the monitoring of truck parameters. The device comprises a housing 5, a timer 14, a mechanism for switching the timer on and off and a locking element. The stepped rod 1 is located in the hollow cylinder 4 with a notch in the middle part. The cylinder 4 is centered in the bore of the housing 5 and fixed relative to it on both sides by a cap nut 6 and a cap 7. The stem has a threaded end on the end, on which the adjusting nut 2 is screwed, restricting the movement of the stem under the influence of the spring 3. The locking element is designed as a mechanical a latch consisting of an L-shaped rod 15 placed in two parallel drillings of the guide sleeve 8. At the end of the rod 15, the control button 16 is screwed and pressed by the spring 17. The short end of the rod 15 abuts a cylindrical portion or end of the pusher 9. 2 yl. "

The invention relates to a lifting and transport technology and is intended to determine the tension and the difference in the lengths of the ropes of a lifting installation.

The aim of the invention is to simplify the design of the device, increase reliability by eliminating shock loads on the timer and improving measurement accuracy.

FIG. 1 shows a general view of the device in section; in fig. 2 shows section A-A in FIG. I.

The device comprises a stepped rod 1 with a longitudinal groove and large divisions at the outer end. There is an adjusting nut 2 on the stem of the stem. Voz10

oscillation waves rod 1 is deflected by a rope. The edge of the longitudinal groove of the stem G appears on the roller 10, causing the movement of the pusher 9, which through the elastic insert 13 of the tip 12 acts on the trigger mechanism of the timer 14. The timer starts counting the time.

The l-shaped rod 15 of the locking assembly under the action of the spring 17 will move in the openings of the sleeve 8 and, with its bent end, restrict the movement of the pusher 9 when the rod 1 returns to its original position. This is necessary due to the fact that when a wave passes the rope makes several transverse oscillations, each of which, re-acting on the rod, the return spring 3 is placed together with the station 5 would cause the timer to be turned off, a foamy rod 1 in the guide Cylinder-After leaving the wave transverse color 4 with a longitudinal slit in the middle part, fixed relative to the body 5 by a nut 6 and a cap 7 having a thread. The return spring 3 is placed inside the cap 7.

The mechanism for switching the timer on and off consists of a guide sleeve 8. a pusher 9 having an operator at one end of the stitching by pressing the button 16 of the L-shaped rod 15 releases the pusher 9 returning the trigger mechanism of timer 4 to its original position

Invention Formula face 10, and spring 11, and on the other, a device for measuring the time of propagation of transverse oscillations in a rope an endpiece 12 with an elastic insert 13, connecting a lifting installation, comprising a stepped stem with a longitudinal groove placed in the housing and a return spring associated with it and a spring-loaded pusher of the mechanism for activating and deactivating the timer with timer trigger 14. The locking assembly of the device contains an L-shaped rod 15 placed in the openings of the guide sleeve 8. At the free end of the L-shaped rod 15 a control button 16 is installed with a spring 30 different guide sleeve, and a locking 17. The timer has a reset button node, characterized in that, in order to simplify the position of the 18. structure, increase reliability The device operates as follows. By eliminating shock loads on Rope-induced colometer timer and improved measurement accuracy, baths propagate in the form of a wave, the blocking unit represents a springy L-shaped cable from the end of the machine from the lifting vessel and pulley. They are of different lengths, placed in a device of inlet holes through a wave, made in the direction of the rope so that the outer end of the push rod bushing, with a short As 1 touched the rope in the plane, the end of the L-shaped rod interacts in which the vibration was excited. When the air is pushed, and the long end of the rod is supplied by a control button reflected from the lifting vessel. 0 oscillation waves rod 1 is deflected by a rope. The edge of the longitudinal groove of the stem G appears on the roller 10, causing the movement of the pusher 9, which through the elastic insert 13 of the tip 12 acts on the trigger mechanism of the timer 14.

The l-shaped rod 15 of the locking assembly under the action of the spring 17 will move in the openings of the sleeve 8 and, with its bent end, restrict the movement of the pusher 9 when the rod 1 returns to its original position. This is necessary due to the fact that when a wave passes, the rope makes several transverse oscillations, each of which, re-acting on the rod, would cause the timer to turn off, After the transverse wave left, the timer would turn off the operator pressing the button 16 L-shaped rod 15 releases the pusher 9, returning the trigger mechanism of timer 4 to its original position Invention Formula Device for measuring the time of propagation of transverse vibrations in a rope  of a lifting device comprising a stepped rod with a longitudinal groove placed in the housing and a return spring associated with it, interacting with the rod-shaped spring-loaded pusher of the mechanism for activating and deactivating the timer with bushing and locking assembly, characterized in that, in order to simplify the construction,
