SU450902A1 - Device for tilting the rocker head - Google Patents

Description

The invention may be used in the repair of deep well oil wells.

The known devices for tilting and lowering the balancer head during the repair of deep well wells, consisting of a rope sling and a pulley system, are unreliable and dangerous.

Also known for handling the movement of goods, the maintenance of carbines, rope sling with friction grippers.

The proposed device differs from the well-known shem that the rope is provided with a number of loops of the rings, in one of which the grip with an additional rope and spring can be alternately installed.

Such an embodiment of the device ensures, when the head of the balancer rotates, the tension of one end of the rope while insuring the other, which allows, without shock and smoothly, to tilt and lower the head of the ball

| Nsira and prevents the possibility of its failure, and putting the device on the head to produce from the floor of the rig.

Fig and 2 shows the described device

It consists of a rope I, the end of which bends around the douche 2, and a number of loops 3 and 4, fixed at both ends with clamps 5, bars b and nuts 7. Carabines-grips 8 are attached to the hinges, To the extreme karabi a loop is attached 10, is a friction clamp.

A screw I having a head with a hole for passage of a bar into it is screwed into the bracket 10. On the other carabip, the grip clings 12 and the insurance rope 13, terminating in loop 14, on the bush 2 there is a loop plan-.and 15, on which there is a screw 16, on the last bar strap 17 and screwing on the nut 18.

Before repairing the well, leave the balancer head in the lower position to the ends of the rope suspension cable attach one end of the rope I with a friction clamp. To do this, slats 15 and 17 are put on the rope about 15-20 cm from the bottom of the balancer head and clamped with a nut 18.

The other end of the rope 1 at. the second friction clamp is attached to the shchzhny part of the balance head arc; for this purpose, the clip 10 is pointed at the arc of the head and clamped by its screw II. A carabiner 8 with a friction clamp is installed in one of the loops, depending on the type — the size of the rocking mill, the cipher of which is applied on the bar. The second carbine b is installed in the second, counting from the eye, a loop (see figure 2). Lead balance rocker in need

for work on repairing the well, the position, the loop 14 is thrown onto the hook of the traveling block, and the device lifts the balance head so that its center of gravity moves from the position c to the position c, i.e. This would cross the axis. This is carried out with the tensioned left part of the rope I, which in this case is a pull.

The rights of his part, which was previously relaxed, will also be tight and will be insured. Spring 12 at the same time, is tensioned;

four

lansir. After that, the tacking unit is lowered and the balancer head finally smoothly flips out. Rights part of the rope I while

5 natnu, and the left is relaxed. After landing, the head is placed on the balance bar while it is lowered onto the ground, removed from the hook and placed in one side. Well repair done

10 in the usual way.

To return the head to its original position after repair: that the carbine 8 clings to the outer loop (see fig. I), hang the device through loop 1 to the hook of the pulley block and pull it (in this case, the right cable will be used) . Since it will be shortened compared to the first positon, the center

. the rope crosses after which the left part of the rope, which in this case will be insured, is pulled.

25 Then the talley block is lowered and the balancer head takes up its working position.

SUBJECT OF INVENTION

A device for swinging the head of the rocker of the pumping unit consisting of a rope with clamps and friction clamps, characterized in that, in order to increase the reliability of operation, the rope is made with a series of loops, in one of which a gripper with an additional rope and spring is installed.
