Abstract

The invention relates to the field of construction and can be used for the installation of pipelines of socket pipes. The aim of the invention is to improve the efficiency of the device by combining installation and testing of pipelines. The device consists of a cross beam on which fixed 2 and 3 grippers of the pipe being laid, fixed 1 and movable 4 grips of the previously laid pipe, rod 5 for hydrotest 5 with two plugs 6 and 7 are mounted. To support rod 5 in a free state there is a gripper 8. When installing the pipeline on the side of the trench, the laid pipe is fixed to the device by inserting the rod 5 and clamping it with the clamps 2 and 3. Then the device is lowered into the trench with the pipe, the pipes are joined and the hydraulic cylinder 10 is produced. boom rod in the pipeline to the cap 6 passed through the formed junction of the pipeline. With the help of plugs 6 and 7, the laid pipe together with the joint with the previously laid pipe is tested. 4 il.

The invention relates to the construction and can be used to mount pipelines of socket-shaped; pipes.

The purpose of the invention is to increase the efficiency of the device operation by combining installation and testing of pipelines.

Fig, 1 shows a diagram of the device before entering the rod into the pipe being laid; general VID1. 2 is a diagram of the device with a stem-rod inserted into the pipe being laid in FIG. 3; a diagram of the device before the Tpy6j strapping in FIG. 4 is a test layout of the pipeline section.

The device for mounting bell-shaped pipes is a mounted traverse on which fixed 1-3 and movable 4 pipe clamps are mounted, a hydrotest rod 5 with a color of plugs 6 and 7 having support rollers. The grippers 2 and 3 are the grippers of the pipe being laid, the grippers 1 and 4 are the previously laid pipe. To maintain the bar in a free state, there is a chuck 8, a grip 4 and a bar 5 with the help of hydraulic cylinders 9 and 10 can be moved along the longitudinal axis of the traverse. The lifting of the traverse is carried out by the lugs 11. , pa6oTaMrojix from the hydraulic system of the pipe-laying machine. The boom is operated from a water hydro station j installed on the crane paver (not shown). The grippers of the grippers 1 and 4 are provided with rollers 12.

The mounting of the socket pipes using the device is carried out as follows.

At the first stage, with all the open- ing Tfcjx grips, except for the supporting weight bar, the traverse is fed to the pipe being laid on the curb of the trenches using a pipelayer and a gripping pipe of 1 and 4 ° is made. With this operation, the rod is centered from the pipe the battle. Then, when the pipelayer moves, the traverse is moved along the pipe on the rollers 125 installed on the grippers 1 and 4. Thus, the rod for the hydraulic unit is 0.

The SRI is introduced into the tube. When entering the pipe of the plug 6, the gripper 8 is opened and retracted outside the pipe. The plugs in the tube move on the available rollers. After inserting the rod 5 into the tube, the latter is gripped by the grippers 2 and 3, and the grippers 1 and 4 are opened. The pipe prepared in such a way is lowered into the trench along the traverse, and with the help of clamps 1 and 4, the laid pipe is centered relative to the previously laid one. Then, using the hydraulic cylinder 9 and the grippers 4 and 3, which have stops for the sockets, the pipes are joined, and with the help of the hydraulic cylinders, the rod is pushed into the pipeline so that the plug 6 passes through the formed joint of the pipeline. With the help of a water hydro station, water is fed into the cavities of the plugs and an appropriate pressure is created, which cuts off the volume of the pipeline to be preliminarily tested. A dedicated section of the pipeline is tested using a water power plant. After the test, the short circuit water of the pipeline is pumped out, the pipeline section is depressurized, the rod is released from the pipe and the cycle is repeated.
