A device for rotating a cylindrical body of a multi-layered high-pressure container, characterized in that the cylindrical body of a multilayer high-pressure container is equipped with a cylinder having a diameter of 0.0,51.

TECHNICAL FIELD The present invention relates to an auxiliary device for mounting and gripping workpieces, and in particular to a device for rotating the cylindrical body of a multilayer high-pressure vessel.

BACKGROUND TECHNOLOGY The problem with uniformly distributing the load on the main and intermediate supports at both ends is that the workpiece tends to flex or shift from a balanced geometric shape to a pendant or ellipsoidal shape. This often occurs in equipment that supports heavy rotating workpieces.
On the other hand, from the standpoint of manufacturing a multilayer cylindrical body for a high-pressure container by continuously winding a steel band, there is a problem in that the weight of the workpiece increases continuously as the winding progresses. Furthermore, the intermediate workpiece support must be periodically separated from the workpiece with gaps formed between the workpiece and the retracted workpiece support in order to allow the steel band to pass through.

The well-known technology includes a device for rotating cylindrical workpieces (see USSR Inventor's Certificate No. 428898 in Volume 19 of "Discoveries, Inventions, Industrial Designs and Trademark Registration" published in Russia in 1974), which rotates cylindrical workpieces. Equipped with a work rotation device suitable for gripping the end. The device further includes two roller support devices, each roller support device including a carriage movable along the rails. The truck has a guide surface and a movable frame adapted to move vertically along the guide surface, and the movable frame is mounted on and supported by a weight-bearing member provided opposite the truck. Each roller support device further includes a roller that supports or carries the weight of the cylindrical portion of the workpiece. The weight bearing member takes the form of a spring.

This prior art device is intended for rotating cylindrical workpieces during the assembly or welding of annular seams, the workpieces being maintained in constant contact with a roller support arrangement. During rotation, geometrical inaccuracies of the cylindrical workpiece, such as deflection along the longitudinal axis and ellipsoidal shape, are compensated by allowing the movable frame to sink due to the compression of the spring under the load of the workpiece. There is. However, the rollers of the two roller supports are adapted to be disengaged from engagement with the cylindrical surface of the workpiece. Therefore, in the case of a device that rotates the cylindrical body of a multilayer high-pressure container in which steel belts are laminated in a spiral manner, the roller support device is engaged with the cylindrical surface of the multilayer container while winding each layer of the steel band. It is necessary to periodically separate the steel belt from the steel belt and provide a passage for the steel belt to pass through. However, prior art devices cannot be used in this case due to the above-mentioned facts.

Furthermore, the device described above allows for non-uniform deflection of the cylindrical workpiece from a uniform geometry along different lengths of the workpiece and varying degrees of compression of the weight-bearing springs, so that the loads exerted by the workpiece are It has the disadvantage that it is not uniformly distributed in the work rotation device and roller support device.

Such uneven load distribution between the rotating device and the roller support device reduces the overall weight carrying capacity of the device.

Furthermore, even if the above device for rotating a cylindrical workpiece is applied to wrap a steel band, it is difficult to compensate for the outer diameter of the cylindrical body, which increases to 400-600 mm with the slight compressive force of the spring of the weight-bearing member. I can't. Also, a weight-bearing member consisting of a spring carries only a load proportional to compression. Therefore, over a wide range of lengths and considerable weights of workpieces, a uniform load distribution between the workpiece rotation device and the intermediate support device is not achieved and overloading of the rotation device is likely.

Furthermore, in order to use the device for rolling up a steel band, it is necessary to ensure a space between the center or intermediate portion of the workpiece and the roller support device for the steel band to pass through. In some cases, the intermediate roller support device must be constructed in such a way that it can be retracted or separated from the cylindrical workpiece. Then, when the intermediate roller support device is retracted, the weight of the cylindrical workpiece is distributed and supported by the two rotating devices at both ends of the cylindrical workpiece, but the rotating devices become a load and the cylindrical workpiece bends. It will end up being lopsided. This continuous bending of the cylindrical workpiece during rotation causes
Misalignment and misalignment of the steel band winding layer occurs, which in turn causes the winding layer to become loosely wound, resulting in poor quality of the cylindrical multilayer body produced by this device.

DISCLOSURE OF THE INVENTION The object of the present invention is to provide a device for rotating a cylinder of a multi-layered high-pressure vessel, which makes it possible to produce high-quality cylinders due to the novel configuration of components and weight-bearing members according to the invention. This makes it possible to increase the weight carrying capacity of the rotating cylinder by uniformly distributing the load between the cylinder rotating device and the intermediate support member.

This object is achieved by a device for rotating a cylindrical body of a multi-layered high-pressure vessel by winding a steel band with the following construction. That is, the device for rotating the cylindrical body of a multilayer high pressure container according to the present invention is located between the cylindrical body rotation device that can grip and rotate both ends of the cylindrical body of the multilayer high pressure container, and the cylindrical body rotation device. It consists of two roller support devices,

The supply and release of hydraulic pressure to the supporting member is controlled according to the output of the counter, and when the steel band passes through the counter from one direction, hydraulic pressure is supplied to the weight supporting member on the rear side of the counter. The hydraulic pressure of the weight bearing member on the front side of the counter is released, and even when the steel band passes through the counter from the opposite direction, hydraulic pressure is supplied to the weight bearing member on the rear side of the counter and the counter The hydraulic pressure of the weight-bearing members on the front side of the steel band is released, and each time the steel band passes, one of the weight-bearing members is alternately moved to a lower position to allow the passage of the steel band, and the other weight-bearing member is The cylindrical body is supported by the roller on the movable frame supported by the weight-bearing member, and the weight of the weight-bearing member increases as the weight of the cylindrical body increases due to the wrapping of the steel band. The device is characterized in that it includes means for adjusting hydraulic pressure in order to adjust the carrying capacity.

By adopting a device for rotating the cylindrical body of the multi-layered high-pressure vessel with the above configuration, the load is uniformly distributed between the cylindrical body rotating device and the roller support device, and the weight of the cylindrical body is reduced as a result of the wrapping of the steel band. to compensate for the increase and alternately pull the intermediate roller support device away from the cylindrical surface of the multilayer high pressure vessel, thereby increasing the weight carrying capacity of the device and preventing partial overloading. Furthermore, the linearity of the longitudinal axis of the cylinder is maintained by preventing the cylinder from deflecting or sagging under its own weight during winding of the steel band. The device described above allows the production of high-pressure vessels, which are characterized by precise linear geometrical axes and tightly wound steel bands.

It's getting old. A pressure regulator 50, 51 is arranged in the return line and is formed as a pressure relief valve. The number of pressure regulators 50 and 51 installed in each of the hydraulic systems 19 and 20 is determined by the number of layers of the steel band 2 wrapped around the cylindrical body 1.

The device for rotating the cylindrical body of the multilayer high pressure vessel operates as follows.

First, the pressure regulators 50, 51 (FIG. 3) of each hydraulic system 19, 20 are connected to the roller support device 5,
The pressure value is adjusted or set to a predetermined weight carrying capacity of 6.

Both ends 4 (FIG. 1) of the cylinder 1 are then gripped by chucks 8 of the rotating device 3. Roller support devices 5, 6 are placed in close proximity to each other in a position intermediate the cylinder 1 and are securely secured by racks 30 and locks 31 (FIG. 2). Then, the lever switch piece 34 of the counter 33 of the steel band layer
(Fig. 1) is brought into contact with the cylindrical surface of the cylindrical body 1,
While bringing the counter 33 into operation, the electromagnet 53 of the flow path switching valve 52 is energized to activate the first weight-bearing stage hydraulic regulator (eg 50) of the roller support devices 5,6. Then, the hydraulic control valve 44 and pump 42 of the pilot hydraulic circuit control the operation of the flow path control valve 41 of the hydraulic system 19.
are respectively turned on. As a result, the flow path control valve 41 of the hydraulic system 19 is opened to allow the weight-bearing member (hydraulic cylinder) 15 (FIG. 1) of the roller support device 5 to communicate with the low-pressure pump 36 and high-pressure pump 39 of the hydraulic system 19. . Then, the low-pressure pump 36 and high-pressure pump 39 of the hydraulic system 19 are activated, and the roller 22 of the roller support device 5 (see FIGS. 1 and 2) is activated.
) is lifted by the weight-bearing member (hydraulic cylinder) 15 until the roller 22 comes into contact with the cylindrical surface of the cylindrical body 1.

As the pressure in the weight bearing member (hydraulic cylinder) 15 of the roller support device 5 increases, the hydraulic system 1
The check valve 38 of 9 is closed, and the weight bearing member (hydraulic cylinder) of the roller support device 5 is operated by the low pressure pump 36.
Hydraulic fluid supply to 15 is terminated. Any further pressure increase in the weight-bearing member (cylinder) 15 of the roller support device 5 is brought about exclusively by the high-pressure pump 39 of the hydraulic system 19.

Weight bearing member (cylinder) of roller support device 5
15 reaches the pressure value of the first weight maintenance phase of the support device 5 determined by the pressure regulator 50 (this pressure value roughly corresponds to the pressure value of the unwrapped cylinder of the steel band 2). The excess fluid (approximately one third of the weight of the body 1) is returned to the oil reservoir 48 of the hydraulic system 19 through the pressure regulator 50.

On the other hand, the roller 22 (first
Figure) is in the lower position. Then, when the first layer of the steel band 2 is rolled up, for example, from the right end side to the left end side in FIG. Generate a pulse. The signal from the counter 33 excites the pump 42 (FIG. 3) of the pilot hydraulic circuit which controls the operation of the flow control valve 41 of the hydraulic system 20, thereby opening the flow control valve 41 of the hydraulic system 20. Weight bearing member (hydraulic cylinder) 15 of the roller support device 6
and the low pressure pump 36 and high pressure pump 3 of the hydraulic system 20.
9 main line will be connected. At the same time, the counter 33 operates the low-pressure pump 36 and high-pressure pump 39 of the hydraulic system 20, and operates the roller 2 of the roller support device 6.
2 (Figure 1) is the weight bearing member (hydraulic cylinder) 1
5 lifts the roller 22 until it contacts the cylindrical surface of the first layer of the steel band 2.

When the roller 22 of the roller support device 6 and the cylinder 1 come into close contact, the low pressure relay 49 of the hydraulic system 20 is activated.
(FIG. 3) causes the electromagnet 45 of the hydraulic control valve 44 of the hydraulic system 19 to drop. At the same time, the safety valve 43 releases the pressure of the pump 42 of the hydraulic system 19, so that the flow path control valve 41 of the hydraulic system 19 closes and pressurizes the inside of the weight-bearing member (hydraulic cylinder) 15 of the roller support device 5. blockade. At the same time, the low pressure relay 49 of the hydraulic system 20 stops the low pressure pump 36 and the high pressure pump 39 of the hydraulic system 19.

The pressure in the weight-bearing member (hydraulic cylinder) 15 of the roller support device 6 increases until it reaches a value determined by the adjustment of the pressure regulator 50 of the weight-bearing capacity of the first stage of the support device 6. This involves closing the check valve 38 of the hydraulic system 20.
A low pressure pump 36 discharges hydraulic fluid into an oil reservoir 48 . When the pressure of the weight bearing member (hydraulic cylinder) 15 of the roller support device 6 reaches a predetermined value, the high pressure relay 55 of the hydraulic system 20 sends a signal to the electromagnet 4 of the hydraulic control valves 44 and 46 of the hydraulic system 19.
5 and 47 are excited, respectively. The flow path control valve 41 of the hydraulic system 19 is brought into a state where it can be opened by the application of pilot pressure, and is opened in response to the pressure applied by the high pressure pump 42, and the roller support device 5 is opened.
The pressure fluid in the weight bearing member (hydraulic cylinder 15) is discharged through a hydraulic control valve 46 into an oil tank 48. Therefore, the roller 22 (first
) is separated from the cylindrical surface of the cylinder, so that the steel band 2 is moved away from the roller 2 of the roller support device 5.
It is possible to continue winding the first layer without being hindered by the second layer.

Following the lowering of the roller 22 of the roller support device 5 to the lower position, the high pressure pump 4 of the hydraulic system 19 is activated.
2 is automatically switched off.

The cylindrical body 1 is supported by the roller 22 of the roller support device 6, and the steel band 2 is continuously wound around the cylindrical surface of the cylindrical body 1.
is working. The pressure value of the weight bearing member (hydraulic cylinder) 15 of the roller support device 6 is determined by the hydraulic system 2.
0, and excess fluid is discharged through the pressure regulator 50 to the oil tank 48. Also, the check valve 38 of the hydraulic system 20 is closed, and the low pressure pump 3 of the hydraulic system 20 is closed.
6 is stopped.

A second layer of steel band 2 (FIG. 1) is rolled over the first layer in the opposite direction.

At the beginning of rolling the second layer, steel band 2
is the roller 22 of the roller support device 5 in the lower position.
The cylindrical body 1 is supported by the rollers 22 of the roller support device 6. When the steel band 2 approaches the counter 33, the lever switch piece 34 is pushed by the side edge of the steel band 2, closing the contact point of the counter 33, and the electric signal of the counter 33 is transmitted to the hydraulic control valve 52 of the hydraulic system 19, 20. One electromagnetic magnet 53 is demagnetized, and the other electromagnetic magnet 54 is excited. This action causes the first stage weight-bearing capacity pressure regulator 50 of the roller support devices 5, 6 to be disengaged and the second stage weight-bearing pressure regulator 51 to be subsequently engaged. At the same time, the counter 33 operates the low pressure pump 36, the high pressure pump 39 of the hydraulic system 19, and the pump 42 of the pilot hydraulic circuit to lift the roller 22 of the roller support device 5. Therefore, the flow path control valve 41 of the hydraulic system 19 is opened, and the weight-bearing member (hydraulic cylinder) of the roller support device 5 is filled with fluid pressurized by the low-pressure pump 36 and the high-pressure pump 39. The rollers 22 of the roller support device 5 are brought into engagement with the cylindrical surface of the cylinder 1 . Subsequently, the low pressure relay 49 of the hydraulic system 19 excites the electromagnet 45 of the hydraulic control valve 44 of the hydraulic system 20, and the flow path control valve 41 of the hydraulic system 20 activates the weight bearing member (hydraulic cylinder) of the roller support device 6. 15 was closed for pressure containment,
The low pressure relay 49 of the hydraulic system 19 then switches off the low pressure pump 36 and the high pressure pump 39 of the hydraulic system 20.

This is accompanied by an increase in the pressure of the weight-bearing member (hydraulic cylinder) 15 of the roller support device 5 to a value determined by the pressure regulation of the second-stage weight-bearing pressure regulator 51 of the roller support device 5 .

The check valve 38 of the hydraulic system 19 is then closed and the low pressure pump 36 of the hydraulic system 19 releases hydraulic fluid to the oil reservoir 48 . When the pressure of the weight bearing member (hydraulic cylinder) 15 of the roller support device 5 reaches a preset value, the high pressure relay 56 of the hydraulic system 19 activates the electromagnets 45, 47 of the hydraulic control valves 44, 46 of the hydraulic system 20. Send a signal to excite. The flow path control valve 41 of the hydraulic system 20 is then opened, causing the fluid in the weight bearing member (hydraulic cylinder) 15 of the roller support device 6 to be discharged through the hydraulic control valve 46 of the hydraulic system 20 into the fluid tank 48 . The roller 22 of the roller support device 6 moves away from the cylindrical surface of the cylinder 1, so that the second layer of steel band 2 continues to be rolled over it.

When the roller 22 of the roller support device 6 is lowered into its lower position, the pump 42 of the hydraulic system 20 is subsequently automatically switched off.

The winding of the second and subsequent layers is carried out almost in accordance with the procedure described above.

As explained above, the device for rotating the cylindrical body of a multi-layered high-pressure container according to the present invention does not change the load on the cylindrical body from the position approximately at the longitudinal center line of the cylindrical body while the steel band is rolled up. They are moved alternately from one support device to the other, while at the same time maintaining a uniform load distribution between the cylindrical body rotation device and the roller support device. Furthermore, by utilizing the apparatus for rotating the cylinder of the multilayer high pressure vessel according to the present invention, the weight carrying capacity of the roller support device is increased relative to the weight increase of the cylinder during winding of the steel band. It has the characteristic of being able to By increasing the weight carrying capacity of the roller support device in this way, it is possible to prevent bending or deviation in the longitudinal direction of the cylindrical body of the multi-layered high-pressure container during winding of the steel band, and to improve the distance between the layers of the steel band being wound. Close contact.

INDUSTRIAL APPLICATION The present invention is suitable for mechanical manufacturing, for example for the synthesis of ammonia, carbamide, methanol, or for hydrocracking and petroleum product reactors, or for steel bands such as columns for heat and mass conversion working under high pressure. It can be advantageously employed in the production of multilayer high-pressure containers formed by winding layers.
