SU421613A1 - DEVICE FOR SUPPLY OF PIPES UNDER THE FLIGHT STRUCTURE OF GAN VALVE - Google Patents

Description

one

The invention relates to a complete mechanization of loading and unloading and installation work in construction.

Devices are known for nodachi pipes under the span structure of a gantry crane, containing a hinged plate on one of the supports of the plone crane, lift, lowering with a cable winch mounted on the crane and provided with guides for the elements moving the pipe.

The proposed device differs from the known topics that the platform is equipped with guides, which are movable along its guide, are installed with the possibility of going beyond the dimensions of the platform and are equipped with carriages, rotatable grippers installed when interacting with the load, and the beams and carriages with cargo are moved with the help provided for on-site drive mechanism, and their return movement - under the influence of tension winch lifting the site. This embodiment provides the mechanization of the seizure of pipes from vehicles.

FIG. 1 shows the on-display device, a general view; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 shows a section along B - B in FIG. 2; in fig. 4 shows a section along B-B in FIG. 2; in fig. 5 - device with beams extended from gaariths of the site, general view; in fig. 6 shows a section along G - D in FIG. five.

The device contains hingedly mounted on one of the supports 1 of the gantry crane and the platform 2, the lifting and which is carried out with the help of a cable winch 3 mounted on the crane. The platform 2 is provided with guides -i, beams 5, carriages 6 and driving mechanism 7 Beams 5 and carriages

6 are connected with the mechanism. 7 chain drives 8 and cables 9, respectively.

Beams 5 have a trough section and are made with rollers 10 that are moved in direction 4. At one end of beam 5

there is an outer projection a, on which pipe 1 rests, and on the other, block 12, through which rope 13 is stored. One end of the rope is fixed on winch 3, and the other end is mounted on carriage 6. Inside balk 5 there are channel bars 14, on which The rollers 15 move the carriage 6. The latter has a housing within which a rotary gripper 17 is open in the slot on the axis 16. The device operates as follows.

For transporting and installing the pipe in the trench, a gantry crane is mounted against the vehicle 18 with the delivered pipe. With the help of the cable winch 3, the platform 2 is lowered onto the curb of the trench;

The means are regulated by outriggers 19. Beams 5 in the initial position do not extend beyond the dimensions of platform 2, and carriages 6 are installed at the ends of beams 5.

By turning on the driving mechanism 7, the beams 5 are extended towards the transnormal means beyond the dimensions of the platform 2, and the carriages 6 pass through the iodine tube. In this case, the swivel grippers 17 occupy a horizontal position and, having passed the pipe, return to the vertical position. Then, the drive mechanism 7 is switched to reverse, and the carriages begin to move toward the platform 2. At the same time, the rotary grippers 17 abut against the pipe and intercept it along the beams 5 until it stops against the projections a. With the pipe resting in the protrusions, the beams 5 begin to move until the pipe stops at the platform 2 under the crane hook. After turning off the drive mechanism 7, the crane hook lifts the pipe and installs it in a trench.

Under the influence of the tension of the cable winch 3 carriage 6 mounted on the beams

5 to its original position for repeating the next cycle.

Subject invention

A device for feeding pipes for the span of a gantry crane, containing a platform hinged on one of the supports of the crane, a lifting and lowering station with the help of a cable winch mounted on the crane and

provided with guides for moving elements of the pipe, characterized in that, for the purpose of mechanizing the seizure of pipes from vehicles, the platform is provided with moving beams along its guiding,

installed with the possibility of going beyond the dimensions of the site and equipped with carriages, carriers of rotary grippers installed when interacting with the cargo, and movement of beams and carriages with cargo

This is accomplished with the help of a drive mechanism provided at the site, and their return movement under the influence of the winch tension of lifting the site.
