Description

one

This invention relates to hoisting-and-transport mechanisms.

Rope-laying machines are known that include a lead screw parallel and connected by mechanical transmission, along which the slider moves, which performs a shuttle movement using a reverse mechanism made with a two-way cam clutch that interacts with a reverse switch mounted on a spline shaft through a clutch with a slider.

In such cable laying devices, the reversal of the slider is carried out using a friction switch, which requires frequent adjustment, and also quickly wears out. It entails replacing the clutch.

In order to ensure reliable operation of the cable lugs: on the ends of the clutch coupling, plugs are mounted alternately interacting in extreme positions with the fingers of the levers arranged on parallel shafts rotating in opposite directions, and on the splined shaft there is a shaped groove interacting with a protrusion switch

FIG. 1 depicts the described rope-laying "; in fig. 2 - reverse node; in fig. 3 shows the node I in FIG. 1 (switch).

Rope-laying machine has a lead screw / along which slider 2 moves, performs a shuttle movement using a reverse mechanism with a two-way cam-type clutch 3, interacting by means of a reverse switch 4 mounted on a splined shaft 5 through a clutch 5 with slider 2. At the ends of the clutch clutch 6 forks 7 are mounted. Between the clutch 6 and the slide 2, a spring-loaded cup 8 is mounted on the hinges. The splined shaft 5 has a shaped groove 9 that interacts with the protrusion W of the reverse switch 4. On the lead screw 1 freely mounted gear wheel U with a lever 12 rigidly fixed on it, equipped with a finger / 5 and with a cam mounted on it POxPumufta 14, two-way cam coupling 5, a gear wheel 15 equipped with a cam half coupling 13. The cam coupling 5 alternately interacts with the coupling half 14 and 16 gears 11 and 15. Gear P interacts with a gear wheel / 8 mounted on the shaft 19, on which is fixed the gear wheel 20, the lever 21, equipped with a finger 22.

Rope laying works as follows.

After turning on the drive 23, the drum 24 of the winch begins to rotate and with the help of

the chain gear 25 transmits the rotation to the shaft / 9 and together with it the lever 21 with gear wheels 18 and 20. The gear wheel 18, interacting with the gear wheel 11, with a single cam coupling half 14 connected to the double-sided cam clutch 3, transmits the rotation to the driving screw 1, which rotates, moves the slider 2, the guide rollers 26 and the clutch 6, moving along the slider shaft 5. Having reached the extreme position, the fork 7 of the clutch 6, engages with the pin 13 of the lever 12, as a result of this the clutch 6 and splined shaft 5 with pomo By means of the spring-loaded cup 8, it rotates sharply, and the shaped groove 9 moves the lug 10 of the reverse switch 4 which interacts with it, which, c. the turn moves the double-sided cam sleeve 5. It comes out of engagement with the cam half coupling 14 of the gear wheel 11. The latter is freely seated on the lead screw 1, at this moment the screw / stops rotating (i.e. is in the neutral position), two-sided The cam coupling 2, moving further, enters the VO interaction with the cam half coupling 16 of the gear wheel 15, which is rigidly fixed on the driving screw 1, but since the gear wheel 15 rotates in the opposite direction of the AI with respect to the rotation gear // (in the presence of a parasitic wheel 17), the lead screw 1 gets the rotation in the opposite direction. In connection with this, the slider 2, with the setting rollers 26 and the clutch 6 slid along the spline shaft 5, begins to move in the opposite direction.

The clutch plug 7 of the clutch 6 leaves the engagement of the finger 13 of the lever 12. When reaching the extreme position, the clutch plug 7 of the clutch 6 interacts with the finger 22 of the lever 21, as a result, the clutch 6 and the slit shaft 5 turn sharply in reverse As the levers 12 and 21 rotate in different directions, the shaped groove 9 moves the reversing switch projection W interacting with it.

4, which in turn moves the double-sided cam clutch 3. It comes out of engagement with the cam half coupling 16 of the gear wheel 15, which is free to sit on the spindle. At this point, the screw / stops rotating because it is in the neutral position. Then the two-way cam clutch 3, moving further, enters into the interaction

with the cam half coupling 14 gears 11, which is rigidly fixed to the driving screw /. But since the gear 11 rotates in the opposite direction with respect to the rotation of the gear 15,

lead screw 1 gets the rotation in the opposite direction.

In connection with the ITE, the slider 2 with the guide rollers 26 and the clutch 6 slid along the slider shaft 5 begins to move again in the other direction. The clutch fork 7 comes out of engagement with the pin 22 of the lever 21.

Further, the duty cycle is repeated.

If necessary, change the rotation

The drum 24 of the winch on the opposite side of the rope-laying machine also acquires the opposite movement at any point of its pai6o4ero range.

Subject invention

Rope laying device including parallelly located and connected by mechanical gearing lead screw, along which the slider moves, which makes the shuttle

movement using a reverse mechanism, made with a double-sided cam clutch, which interacts with a reverse switch mounted on a splined shaft through a clutch with a slider,

characterized in that, in order to ensure the reliability of the cable-laying machine, on the ends of the clutch are mounted forks alternately interacting in extreme positions with the fingers of the levers located on parallel shafts rotating in opposite directions, and on the spline shaft there is a shaped groove interacting with a protrusion switch
