.V The invention relates to the field of psR

pipelines, in particular, to devices for applying monolithic thermal insulation to pipelines of heat networks.

A device for applying monolithic thermal insulation is known, comprising a detachable form, a filling device on the frame and a device for removing gases. Moreover, the casting device is installed on the frame of the movement, and the detachable form is fixedly mounted. However, it does not provide for the suction of harmful substances from the open form in the process of pouring it, and, moreover, it does not provide for the complete suction of harmful substances even when the form is closed because of the leakiness between the apron and the pipe l.

The purpose of the invention is to mechanize the application of thermal insulation and to eliminate the harmful effects emitted during the expansion of harmful substances.

This is achieved by the fact that the form of the frame mounted on the frame is movable horizontally on the hinges, and the device for filling the composition of synthetic resins, gas formers and technological additives is mounted stationary.

FIG. 1 shows a general view of the installation; FIG. a - a partial section along aa, in fig. one; in fig. 3 is a partial section along BB in FIG. one; in fig. 4 - cam mechanism.

The device consists of a frame with guides 1, horizontally opened form 2 on hinges, pushers 3, pressing plates / cams 5, carriage 6, filling device 7, catchers 8, pressing and fixing device 9, device for (Opening closing form 1O , exhaust ventilation box 11, expansion chamber 12, drive cable 13, drive 14, drive mechanism 15, and lubrication device 16. On frame 1 it is mounted movably in its guide carts 6, on which a replaceable floor is fixed inside form 2 The form is made of two halves on the hinge. Thermal insulation is applied to the pipes during installation operation. The installation is started from the control panel after the installation of the open form in the initial position, as shown in the drawing (Fig. 1, 2, 3) and laying into the internal cavity of the pipe intended for and ollation. The starting material for obtaining thermal insulation is fed to a casting device where the composition is mixed. After the start of the installation, the drive mechanism 15 through the bank 14 by means of the cable 13 drives the carriage 6 with the form 2, which turns on the track sensor, after which the foaming composition is uniformly poured into the open mold 2. The composition is stopped after the second track sensor is turned on. In the process of further movement of the cart 6, the lid of the filled form 2 with its fist 5 hits the catchers 8 disengaged from the pushers 3 and guides them through the screw groove of the device for closing and opening the Cover of the Form 1O. Fist 5, moving ho to screw slot 1O, closes the lid form 2. To reduce friction when moving along the groove, the fist has a bearing at the end. The slot 17 of the device for closing and opening 10 of the mold 2 is screw-shaped. The edges of the groove have strips welded to the wall of the device 10, perpendicular to the wall of the device 10, ensuring smooth movement of the cam movement. The closed mold 2 with its clamping plates 4 interacts with a device for clamping and fixing under a certain pressure the crinkles of the mold 9, which is achieved by adjusting the device itself. 9. At the time of fixing the cover of the tele with the form, it is completely inside the swelling chamber. The swelling of the composition occurs with the release of gaseous harmful deposits, which the swelling chambers 12 are forcedly removed to the ducts 11 by the exhaust ventilation box. After the swelling of the composition is completed and it becomes a solid, the drive mechanism 15 that drives the cart the closed mold 2. At the time of the start of the movement, the pressure plates 4 come out from under the influence of the device 9 and, with the fist 5 and the device 1O, the cover of the form 2 opens. After opening the lid, the cart 6 with the lid of the form 2 open continues to move in / direction. The cart 6 with the open lid of the mold 2 stops after the final exit of the mold 2 from the swelling chamber 12, after which the pipe with the applied monolithic thermal insulation is inserted. form, and the form itself is cleared of residual insulation. The cleaned g form 2 moves in the reverse direction. At the moment of passage of the intumescent chamber, the inner surface of the open form is lubricated with a special lubricant, which prevents the insulation from sticking to the walls of form 2. After applying the opened form 2 to its original position and laying it in. her new pipe, the process is repeated. The formula of the shadow shade 1. A universal semi-automatic installation for applying monolithic thermal insulation, including a detachable truss with a railing, a casting device on the frame and a device for removing gases, characterized by is movable on the frame relative to the fixed filling device, and has a cap control device of the c. cam form. 2. The installation according to claim 1, characterized in that the cam mechanism is made in the form of a cylindrical casing mounted on the frame with a spiral cut, which includes a finger with a bearing fixed on the cover.
