Description

The invention relates to pipe welding production, and more specifically to devices for transporting and collecting welded pipes in drives.

A device is known for transporting and collecting pipes to storage devices (see AS USSR No. 217341, class B21B 26/02, decl. 11.11.66, publ. 07.05.68).

This device contains a trough of two guides rotatable from the pneumatic cylinders and pockets for collecting pipes mounted on different sides of the trough.

The main disadvantage of the device for transporting and collecting pipes into storage tanks is the inability to separate defective pipes from suitable pipes.

The next drawback is the lack of reliability of the equipment, since when the pipe is rolled into a pocket, a "pipe hang" is possible.

The disadvantage of this device is damage to the outer surface of the rolled products or pipes during their transportation through the gutter.

Of the known devices for transporting and collecting pipes to drives, the closest in technical essence is the device described in the patent of the Russian Federation No. 2169687, class. B65G 47/38 claimed 05/19/98, publ. 06/27/2001

The device comprises a vehicle made in the form of a pair of rollers mounted on a bed one above the other with cushions and bearing bearings, a beam with single rollers. The lower roller of the vehicle is idle, and the upper roller is driven with a compression screw and a clamp pneumatic cylinder. The beam is installed in bearing bearings located on racks. Pockets for collecting pipes are installed on both sides of the beam. Pockets are made in the form of racks and chains fixed on them in rubber sleeves.

The main disadvantage of the device for transporting and collecting pipes into storage tanks is that there is no way to separate defective pipes from suitable pipes.

The second disadvantage of the device is the lack of precise stopping of pipes of different lengths at their ends, since it is impossible to adjust the pressing force of the upper roller in the required range.

The next disadvantage is the lack of reliability of the equipment. This is due to the fact that when dumping pipes of small diameter and increased curvature, uniform rolling of the pipes into the pocket is not ensured, since their "freezing" is possible.

The objective of the present invention is to provide a device that allows for the separation of defective pipes from suitable pipes, to increase the stopping accuracy of welded pipes of different lengths at their ends and the reliability of equipment.

This object is achieved in that a device for transporting and collecting pipes into drives containing a vehicle in the form of a pair of rollers mounted on a bed one above the other with pillows and bearing bearings, the upper of which is a drive with a pressure screw and a pressure hydraulic cylinder, a beam mounted on racks with according to the invention, provided with idle rollers, pockets along the beam for collecting pipes in the form of racks and chains attached to them in rubber sleeves, according to the invention, are equipped with parallel to the beam yoke racks with pockets fixed on them in the form of chains with rubber sleeves for collecting defective pipes, axles are mounted in the vertical holes of the beam on the slide bearings, at the upper ends of which levers with rubberized rollers are rigidly fixed for dumping pipes, and on the lower ends - levers rotated by traction and hydraulic cylinders, on the sides of the beam are made platforms with collars perpendicular to its axis for mounting removable end stops with spring-loaded shock absorber for pipes, with additional sleep racks They are provided with axles located in the bearings on which the arm-overlap pockets for collecting defective pipes are cantileverly mounted on one side, and on the other hand, levers connected through rods, a system of levers and a transmission with a hydraulic cylinder rod installed at the zero mark of the foundation, in addition, between the pillows and the pressure screws of the upper roller of the vehicle are spring measuring means.

Such a constructive implementation of the device for transportation and collection of pipes will allow to separate the defective pipes from the fit ones by installing additional racks with pockets fixed to them for collecting defective pipes and introducing levers with rollers for pipe discharge.

The constructive implementation of the stops and the possibility, due to the spring measuring means, of regulating the necessary pressing force of the upper roller to the lower one, makes it possible to precisely stop the welded pipes of different lengths at their ends.

Thanks to the installation of levers with rollers, uniform dropping of pipes is ensured, which increases the reliability of the equipment.

To explain the invention, a specific embodiment of the invention is provided below with reference to the accompanying drawings, in which:

A device for transporting and collecting pipes to drives contains a vehicle, a beam 1 with idle rollers 2 and pockets 3.4 for collecting suitable pipes. The vehicle is made in the form of a pair of rollers 6 mounted one above the other in a frame 5 with pillows 7 and bearing bearings 8. The upper drive vehicle roller with a pressure screw 9 and a clamp hydraulic cylinder 10. Beam 1 is mounted on racks 11. Pockets 3 are located along beam 1 , 4 for collecting suitable pipes, made in the form of racks 12 and chains 13 fixed on them in rubber sleeves 14. The device for transporting and collecting pipes into storage rings is equipped with additional racks 15 located parallel to beam 1 with a fixed E them pockets 16 in the form of chains with rubber sleeves for collecting defective pipes. In the vertical openings of the beam 1, axles 18 are mounted on the sliding bearings 17, at the upper ends of which are levers 19 with rubberized rollers 20 are rigidly fixed for dumping pipes into pockets 3 and 16, and on the lower ones are levers pivoting 21 using rod 22 and hydraulic cylinder 23. On the lateral sides of the beam 1, platforms with collars 24 are made perpendicular to its axis for fastening removable end stops 25 with spring-loaded shock absorber 26 for pipes. Additional racks 15 are parallel to the racks 11 and are equipped with axles 27 located on the bearings, on which the levers-overlaps 28 of the pockets 16 for culling the defective pipes are mounted cantileverly on one side, and the levers 29 connected through rods 30, the lever system 31 and transmission 32 with the rod of the hydraulic cylinder 33 mounted at the zero mark of the foundation. Between the pillows 7 and the pressure screws 9 of the upper roller of the vehicle are spring measuring means 34.

A device for transporting and collecting pipes works as follows.

In the process of cutting a continuous welded pipe 35 in a cutting device (not shown), its front end is located in the plane of the rollers 6 of the vehicle. Pressure is supplied to the piston cavity of the hydraulic cylinder 10. The upper roller 6 continuously rotating from the drive is pressed against the pipe with a force controlled by means of measuring means 34. The pipe is transported along the rollers to the end stop 25, which is installed on various platforms with collars 24 depending on the length of the welded pipe cut off.

Next, the hydraulic cylinder 23 is turned on to dump a suitable or defective pipe into the pockets 3.16 using the levers 19 with rubberized rollers 20. The suitable pipes enter the pockets 3, and the defective pipe into the pocket 16 with the blocking lever raised with the hydraulic cylinder 28. The levers the overlappers 28 of the pockets 16 rise through the rods 30, the system of levers 31 and the transmission 32.

After filling the pocket with 3 suitable pipes, they are removed by an electric bridge crane (not shown). Without stopping the unit, the levers are installed in the overlapping position of the pockets 16 defective pipes and suitable pipes through the lever-overlap 28 enter the next pocket 4 for suitable pipes.

The proposed device for transporting and collecting pipes to drives, in comparison with the known ones, will ensure separation of defective pipes from suitable pipes, increase the stopping accuracy of welded pipes of different lengths at their ends and equipment reliability.
