Abstract

This invention relates to pipe production. The purpose of the invention is to reduce noise when hauling a defective rolled product from a stream and storing it in a pocket. The transmitting levers 1 with their rotational drive 3 transmit rental 29 from working position 1 to working position P and into pocket 4. The levers have a curved shape that encloses the pocket, and the O-axis of their rotation is located under the pocket. Near the initial position 1, a rolling lowering mechanism is installed, made in the form of pivoting levers 6 mounted on output shafts 7 of gearboxes 8 connected to a common drive. At the end of the levers 6, a support roller 11 and an asterisk 12, connected by a chain 13 with an asterisk 14 mounted on the output shaft and fixedly mounted on the housing of each gearbox 8, are pivotally mounted. The pushers 20 are installed with supporting prisms 21 under the pocket. a hole is made, on the walls of which the gate valves 24 are hingedly mounted to allow rolling in the upward direction. To prevent pipe seizure, movably mounted brackets 25 with idle rollers 26 are provided. In the case of defective rolled products, levers 1 are retained at position P. Hire 29 which lies on support rollers 11 of position 1 is lowered to position W by means of levers 6. When turning levers 6 of chain 13 When rolling around the fixed sprockets 14, the sprockets 12 and, consequently, the support rollers are driven into rotation. The direction of rotation of the support rollers is opposite to the direction of rotation of the levers 6, which prevents the car from shifting during lowering. The position of the end face remains unchanged. From position III, rolling is moved to position IV by means of mobile platforms 15. 5 Il.

The invention relates to coarse production, and more languidly to a device for transferring pipes (rolled products) from one technological operation to another with a sample of a stream of defective pipes, as well as piling into pockets.

It is an object of the invention to reduce noise when sampling rejected rolled products from a stream and storing it in a pocket.

On f-ig. 1 shows the proposed device, top view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a section of YYD in FIG. .

The receiving-transmitting device contains transmitting levers f, mounted on shaft 2, having a 3-turn drive for transmitting pipes from position I to position i for further machining in nympower 4, mounted on base 5. Transmitting levers have a curvilinear shape covering the pocket, and Their axis of rotation is located under the pocket. A sampling mechanism from the flow of defective pipes is installed on the side of the pocket near the initial position, made in the form of pivoting levers 6 mounted on the output shafts 7 of gearboxes 8 connected to a common drive 9. At the free end of each of the levers hinged by means of an axis 10 are mounted support roller PI sprocket 12, connection1П1а chain 13 with Sprocket 14 mounted on the output shaft and fixedly mounted on the Koptiyce of each of the gearboxes. Under the pocket, on the base, there is a horizontal cross-section 1 tube interchange mechanism, made in the form of mobile platforms 15 with support prisms 16 connected by a common shaft 17 through 18 driven 18 wheels. Under the pocket, pushers 20 are installed, for example rack and pinions 2 connected through a shaft 22 with a drive 23. The bottom of the pocket opposite the pushers has a longitudinal through groove, on the walls of which Sharinrio there are stop valves 24 for the passage of pipes in one direction (up). To protect the surface of pipes from scoring and exclude pipelines G1 from within crown 1 25 with idle rollers 26, mounted on the walls of the pocket opening with the possibility of movement to adjust to different diameters of pipes. Crown holders 27 for hooking an overhead crane when unloading are rough from the pocket. All mechanisms of the device are equipped with sensors (not shown). The brackets 25 rolls to the groove walls with bolts 28.

The device works as follows.

The incoming pipe (fig. 1 tube 29 from the rack switch 30, if it is suitable, is transmitted to position AND by levers 1,

which, by turning irides 3 by 90 ° around the axis O, gently lower and shift the pipe to the support rollers of position P. By turning on the drive 3 in the opposite direction, the levers 1 return to position I behind the forward pipe. If the pipe is defective, then the levers delayed at position 11. The pipe, which in this case lies on the support rollers 1 in position 1, is lowered down to position 111.

To do this, include P1) and the input 9n levers 6, turning together with the shafts 7 of the gearboxes 8 by 180 °, lower down and lower the tube onto the supporting elements 16 of the platforms 5. At the same time, the support rollers 1 1 occupy the attachment below the support prism. When the levers of the chain 13 are rotated, rolling on the fixed stars of the dials 14, the sprockets 12 and, therefore, the supporting rollers rotate, and the direction of rotation of the supporting rollers is oppositely naira. By turning the levers, this prevents the pipe from shifting during the lowering of the iiUk .; and the position of the pipe end remains unchanged. From position P1, the pipe moves to position IV with the help of mobile platforms. From position IV, by moving upward the pushers 20, the pipe enters the pocket 4, retracts the gate valves 24 rotated on the hinges, and the passage between the idle rollers 26 installed in the longitudinal groove of the pocket.

0 Shut-off valves, after passage of the pipe, are rotated to their original 1 position under the action of their own weight and prevent the pipe from falling out of the pocket.

After that, the pushers 20 lower and the platforms return to the position

5 P1. The levers 6 return to their original position at position I. The cycle then repeats. After loading the pockets with pipes, they are removed with help from the pavement on the crane.

The proposed device, in comparison with the Known ones, allows silently, without strikes, to transfer pipes from a position on the 103 ITS and put them in a pocket, which allows to improve the working conditions of personnel, reduce the incidence of 5 noise levels. The possibility of unaccented transmission and pipe laying allows protecting their surface and threads from damage. /
