Description

In accordance with the invention, for the mechanized sealing of the joints of cast-iron water pipes, in order to evenly seal the material in the pipe joints, a pressure sleeve is used, consisting of two equal parts fixed in a sliding buttress clamp clamp.

Pressing the UmNoi mog together with the pressure bushing is not effective with the iomoptyo rests on the hydraulic iress rods.

To control the pressure created on the pressure bushing to ensure the quality sealing of the joints, a pressure gauge is installed on the oil oil line.

FIG. 1 depicts the proposed crisiocomplaine in Yilan; in fig. 2 - in a section along the line (AB) in FIG. one; in fig. 3 is a longitudinal section of the LINE (IOP) in FIG. 2

The equipment consists of a detachable yoke, made in the form of two I-clams (1) and (2) (Fig. I), on which hydraulic lines (3) are mounted. Half-jacks can be moved apart, rotating around an axis located above the pipe.

The half clamps (1) and (2) are connected by four straps (4) to the stop noluhomuts (5) and (6), fixed on the socket of the previously laid pipe.

Compaction of the material in the joint is carried out with the help of a push bushing

(7), cut along into two equal parts, fastened in a sliding strut (4) on a symmetrical yoke (8). The rods of the presses (3), and extending from the cylinders, are moved along the tube by the nay; the clamp and the press sleeve entering the socket are moved.

The process of installing the tool in the working position on the pipe consists in that the half-sleeves (1) and (2), (o) and (6) are moved apart, lowered onto the pipe and then shifted, covering it. Simultaneously move apart and then attach attached j; STAA AM THE SLIPPING CLAMP AND Bushing.

The pressure in the cylinders of the press is carried out with the help of a manual plunger, an electric pump mounted on a special trolley, together with a tank for maela and 1: non-wound opening (H.I of the drawing not shown).

The flow of oil from Pasos to the cylinder; Tresses are produced by rubber through the nipples (9). Cylinders are connected separately to feed tubes (10) and (11). For one pair of cylinders, the oil is fed directly after the tee (12), and to the other, through the luap, a two-port crane (13).

The articulated valve makes it possible to rotate the oil tubes to open the half-sleeves.

When moving the pistons and presses forward, the oil in front of them i; top hats 15s; tube but:

(14) (15) to the return hose to the oil tank mounted on the trolley. In order to move the pressure nozzle in the opposite direction, the oil under pressure is supplied to the R cylinders of the presses in front of the pistons and pushes them back. At the same time, the oil in the cylinders behind the oil is squeezed into the cam. To change the direction of oil movement in the system, a two-way tap switch is used.

Changing the position of the crane handle "working stroke -" reverse stroke changes the direction of movement of the pistons of the presses and the pressure nozzle.

Seal the joint using the described fixture 5 as follows: on the smooth end of the cast-iron pipe (16) (Fig. 2 and o) the caulk strings are twisted and manually inserted into the spherical spruce (17) without sealing.

Then the oil pumps and the pressure bushing are turned on, and forward, pushes the caulker into the depth of the slot and seals it.

After that, an asbestos-cement mixture is introduced into the slot and is also sealed with a sleeve.

Mounted on nano 1H011 oil pipes; and a pressure gauge (not yet: an) in the drawing allows controlling the pressure with which the sealing material is pressed in.

At the end of the press-in of the joint, the device is removed from the pipeline and transferred to the following joint, where all the operations are repeated) R11) T | l described vyty order.

Subject and: i about b)) e t (n and

1. A device for mechanized sealing of the joints of cast-iron water pipes using hydraulic presses, characterized in that, in order to smoothly seal the material in the pipe joints, a pressure sleeve is used, consisting of two equal parts secured in a pressure clamp that slides over the clamps.

2. Appropriateness for and. 1, in that the pressure clamp is moved by the hydraulic press rods abutting against it.

3. Adaptation. 1 and 2, that is, so that a pressure gauge is installed on the oil pipe to control the pressure generated by the pressure sleeve, which ensures a good seal of the joints.
