The invention relates to lifting devices, namely, to special winches for lowering a borehole measuring instruments.

The aim of the invention is to reduce the size of the winch.

Fig. 1 shows the measuring cable winch, general view; nafig, 2 section LL in FIG. 1; FIG. 3 is a section BB in FIG. 2,

The measuring winch contains a mounting plate 1, on which a hollow shaft 2 is rigidly fixed with an engine 3 and a gear 4 inside. An integrated clutch is mounted on the output shaft 5 of this gear, consisting of a roller one-way clutch and a friction safety clutch, which include the driving 6 and the driven 7 disks, the rollers 8, the toothed rim 9, the friction disk 10 and the clamping nut 11. The toothed rim 9 is engaged with the toothed wheel 12 rigidly connected to the side wall 13 of the drum 14 mounted on the shaft 2, On the running screw 15 of the mechanism for laying the measuring wire 16 located above the drum 14, the Maltese cross 17 is installed, which together with the surface 18 of the wall 13 establishes a transmission that informs the drive of the slide 19 a discontinuous movement, the slide being connected to the carrier 20 of the measuring wire 16 by means of a roller conveyor representing an elastic tape 2I,

transporter. The measuring wheel 24, installed with the possibility of rotation on the shaft 2, is engaged with a gear that transmits motion to the counting register 27. Each turn of the drum 14 is accompanied by the -Boe displacement of the slide 19, equal to the diameter of the wire 16, If this wire is pulled by a probe , then turning on the mechanical drive will cause it to wind off the drum 14. If the probe stops in the well, the drum 14 will automatically stop. 1 h, n, f, 3, ill.

equipped with holders 22 with rotating rollers 23,

The measuring wire 16 is passed between the elastic tape 21 and the rollers 23, and the measuring wheel 24 is planted rotatably. On the shaft 2, A tooth 25 is made on the rim of the measuring wheel, which is in engagement with gear 26, transmitting the movement of the wheel 24 to the counting register an assembly 27 attached to the mounting plate 1. On the outer surface of the shaft 2 there is at least one ring 28 insulated from the shaft, which cooperates with a sliding element 29 attached to the drum 14 and electrically connected to the end of About the wire 16 on the side wall of the drum, on which the gear wheel 12 is also attached. This wheel has an internal gear and interacts with the gear wheel 30 located on the shaft 31, the shaft 31 rotates in bearings inside the shaft 2 and ends with a lock 32 to interact with the handle tkoy

A probe 33 is electrically connected to the measuring wire 16, with which the value of the monitored parameter in the borehole is measured.

The wire 16 suspended vertically and tensioned by the probe mass is inserted into the groove of the measuring wheel 24 and then passes through the carrier 20 to the roller conveyor 21, 22, 23 and to the slider 19, evenly laying the wire over the entire surface of the drum 14. Each turn of the drum 14 is accompanied by an axis If the wire 33 is pulled by probe 33, turning on the mechanical drive will cause it to wind off the drum 14. If probe 33 stops in the well, rotating sajj 5 will move the rollers 3, which will cause The gearing rim 9 and the driving disk 6 are not in motion, as a result of which the drum 14 will stop.

With the engine off, the 3-metering wire 16 can be wound on the drum 14 with a knob mounted on the lock 32. The rotational torque of the transmission and the engine prevent rotation of the drum 14 in the opposite direction. It is possible to lower the probes 33 into the borehole by loosening the clamping nut, as a result of which the driving disk 6 and the shaft 5 are separated. The probe 33 is electrically connected by the measuring wire 16, the sliding element 29 and the ring 28 with the corresponding measuring circuit,
