Pusa has a feed rod for shipping rods (TS), which has a locking mechanism in the form of a ratchet with a dog. The feed unit is made in the form of two pairs of leading rollers 12 fastened to gear wheels 15 Rollers 12 are connected by parasitic gears 6. Gears 16 and rollers 12 are mounted on axles 14 and 17. Axes 14 of rollers 12. are fixed in both parts 3 and 4 of the body, and in part 4 of the axis 14 is fixed D

The invention relates to mining and can be used for geophysical surveys of military, horizontal and inclined wells.

The aim of the invention is to increase productivity and reliability.

FIG. 1 shows the proposed device, a general view, 1 in FIG. 2 is a section A-A in FIG. 1.1 in FIG. 3 - section BB. in FIG. 1) in FIG. 4 shows view B in FIG. 5 - section GGD in figure 1.

The device for feeding the logging tool into the well contains a guide, a pipe t on which a housing consisting of a fixed 3 and a movable 4 parts is mounted on the nut 2. The guide tube 1 is hingedly fastened to the telescopic rods 5 and has sleeves 6. The sleeves 6 have grooves for cable penetration 7. The movable part 4 of the housing is mounted on two guides 8 with springs 9. The device has an eccentric 10 fastened with a handle 11. In the movable 4 and fixed 3 parts of the housing there are two pairs of leading rollers 12 for moving the transport rods 13. The driving rollers 12 are mounted on axles 14 together with gears 15. Gears 15 of their own interconnected via spurious gears and 16 mounted on shafts 14, 17. The axes of the drive rollers 1 in the movable portion 4 of the housing zakreple- us with the possibility of longitudinal movement in the slots 18. The apparatus is provided with straps 19, one end of which is mounted on shafts 14, and another for longitudinal movement. On the axis 14 of the rollers 12 in the body part 4, the ends of the strip 19 are installed, the other ends of which are mounted on the axes 17 of the gears 16. Into the guide tube 1 insert an instrument fastened to the TS. The end of the TSH is passed through the body. The rollers 12 come into contact with the TS 13. The axis 14 or 17 is rotated with the drive handle and the device is fed into the well. 5 il.

on the axis 17. On the axis 14 of one of the leading rollers 12, a locking mechanism is installed, made in the form of a ratchet 20 with a dog 21. The ends of the axes 14 and 17 are designed to be fitted with a driving handle (not shown). (

The device works as follows.

A device (not shown) fastened to the transport rod 13 is inserted into the guide tube 1. The cable 7 is placed in the grooves of the sleeves 6. The guide tube 1 with the transport rod 13 and the instrument inserted into the well is fixed and fixed. Rotate the arms 11 compress the spring 9. In this case, the movable body part 4 moves away from the fixed part 3 of the body and the driving rollers 12 are separated. By means of a nut 2, they fix the fixed part 3 of the body to the guide tube 1. The end of the transport rod 13 is passed through the body. Turn the handle 11 in the opposite direction. In this case, the movable part 4 of the case is spring-loaded 9 and under the action of its own weight: against the stationary part 3 of the case, and the drive rollers 12 come into contact with the transport bar 13. Rotate the axle 14 or 17 with the drive handle and feed the transport bar 13 into the well. Simultaneously with the feeding of the transport rod 13, the buildup is carried out until the predetermined depth of the well is reached. Removing the instrument from the well is carried out in reverse order.

The proposed device provides high performance and reliability by eliminating idle strokes during boom buildup and preventing their fracture.
