Description

The invention relates to the installation of bell-shaped water and sewage pipelines.

The purpose of the invention is to ensure the reliability of the hammering of a bell-shaped pipe joint.

FIG. 1 shows a diagram of the device; in fig. 2 - capture scheme with centralizers; in fig. 3 is a diagram of a caulking mechanism; FIG. 4 is a view A of FIG. 3

The device consists of a body 1, which is fixed on the load-carrying beam 2. At the end of the latter, a fixed gripper 3 is fixed. The housing 1 consists of a frame 4, on which a fixed fork 5, a fixed 3 grip 6 and guides 7-10 are fixed.

The movable gripper 11 and the mechanism 12 dp of the caulking are mounted on the guides 7, 8, 9 and 10 with the possibility of movement. The movable nip P is connected to the hydraulic cylinders 13 for its movement along guide rails. The hydraulic cylinders 13 are fixed on the thrust fork 5. The mechanism 12 for the caulking is connected to the hydraulic cylinders 14.

The fixed grippers 3 and 6 mate with the pipe 15 to be laid, on which the blank 16 of sealing material is put. The thrust fork 5 and the movable gripper i1 mate with the previously laid pipe 17, the hydraulic cylinders 14 are fixed on the cheek 18 of the fixed gripper 6.

A stationary gripper 6 is mounted between the cheeks 18 and 19, rigidly connected to each other and the body 1. The guides 7-10 pass through the cheeks. On guide 7 and 8, two pairs of levers are rotatably mounted. The lower pair of levers 20 and 21 has shoulders located on both sides of the guides 7 and 8, and at the upper pair of levers 22 and 23, the shoulders are located above the guides 7 and 8..

The upper arm of the lever 20 is connected to the lever 23 tons of goy 24, and the upper shoulder of the lever 21 - with the lever of 22 tons of goy 25 The lower shoulders of the levers 20 and 21 are connected by rods 27 and 28 to the stem 26 of the hydraulic cylinder 29 fixed on the cheeks 18 and 19 .

The distance from the point of contact of the NIN lower arms 20 and 21 with the pipe 15 to the center of their rotation on the guides 7 and 8 (arm 1) is equal to the distance „

from the point of contact of the upper arms 22 and 23 with the pipe 15 to their center of rotation on the guides 7 and 8 (arm 1), and the distance from the center of rotation of the levers 20 and 21 on the direction of fastening 7 and 8 24 and 25 on these levers (shoulder 1) are equal to the distance from the center of incidence of the levers 22 and 23 on guides 7 and 8 to the mounting points 24 and 25 on these levers (shoulder 2), therefore, the centering of the tube 15 relative to the directions 7 and, 8.

The movable centralizer of the gripper 11 has a similar construction, but on the guides there are sliding bushes on which levers are fitted, which makes it possible to move along the guides 7 and 8,

The lower arms 20 and 21 are connected by rods 30 and 31 to movable sectors 32 and 33 of the mechanism-12 for a caulking, which consists of the upper coinage 34, attached to the cheek 35, mounted on the rails 7, 8, 9 and 10., and lower Chekanov 36 and 37, fixed on sectors 32 and 33.

Installation of socket pipes using the proposed device is performed as follows.

Using the hook of the lifting mechanism, the device is guided to the pipe 15, the smooth end of which is preloaded with the workpiece 16. The device with the opening grips 3 and 6 is lowered onto the pipe 15, the pipe 15 is fixed and the grippers 3 and 6 are closed. Then the device with pipe 15 is lowered into trench so, to persevere plug

5 went down on the previously laid pipe 17, and podvrszhny capture 11 seized the bell of the pipe 17, Include hydraulic cylinders 29 and levers 20, 21, 22 and 23 centralizers of the movable 11 and fixed 6 grippers, fix the pipes 15 and 17,

Due to the fact that the fixed grip 6 and the movable grip 11 are mounted on the common guideways 7 and 8, as a result, the coaxiality of the pipes 15 and 17 is ensured.

When closing the grip centralizer

6caps 36 and 37 and sectors 32 and 33, connected to levers 20 and 21, clasp the pipe, similar to cylindrical cuts with a check 34.

By means of cylinders 13, the movable gripper 1I is moved, with the result that the smooth end of the pipe 15 with the workpiece 16 is inserted into the bell of the pipe 17 by a specified amount. Then, the hydraulic cylinder 14 moves the hammering mechanism 12 to the socket, with the chisels 34, 36 and 37 crushing the workpiece 16 into the socket.

After staking the hydraulic cylinder 14 is withdrawn from the socket, the grippers 3, 6 and 11 are opened and the pipes 15 and 17 are released.

The device is removed from the trench and fed to another pipe, the installation of which is similar.
