Description

A circular support device for liquid hydrogen tank steel plates used in plate rolling machines Technical Field

[0001] This utility model belongs to the field of steel plate rolling production technology, and specifically relates to a liquid hydrogen tank steel plate rolling support device applied to a plate rolling machine. Background Technology

[0002] At 200m 3 The manufacturing process of liquid hydrogen tanks requires a W12-30*2500 four-roll plate rolling machine. This machine has a maximum rolling diameter of 2000mm, which is insufficient for rolling steel plates for liquid hydrogen tanks with a diameter of 4300mm. Replacing the plate rolling machine would be too expensive. Purchasing a commercially available support frame for this machine would be problematic because it has four power mechanisms that drive the four corners of the support plate, raising and lowering each corner to support the 4300mm diameter liquid hydrogen tank steel plate. This not only incurs high purchase and installation costs but also high energy consumption and operating costs. Summary of the Invention

[0003] The technical problem this invention aims to solve is to address the shortcomings of existing technologies by providing a reasonably designed, simple, and easy-to-use circular support device for liquid hydrogen tank steel plates used in plate rolling machines. This device can produce liquid hydrogen tank steel plates with a diameter of 4300 mm or greater.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A circular support device for a liquid hydrogen tank steel plate ring applied to a plate rolling machine is characterized in that the device includes a column, a crossbeam, and a support frame for supporting the liquid hydrogen tank steel plate ring. The bottom end of the column is fixed to the frame of the plate rolling machine. A lifting mechanism for the crossbeam is provided on the upper part of the column. One end of the crossbeam is connected to the lifting mechanism, and a vertically arranged rotating baffle is installed at the other end of the crossbeam. The bottom of the rotating baffle is hinged to a hinge support provided on the crossbeam through a hinge shaft. A return spring is installed on the hinge shaft to reset the rotating baffle from a horizontal state to a vertical state. A horizontal adjustment mechanism for adjusting the horizontal position of the support frame is provided at the top of the crossbeam.

[0006] The support frame includes a horizontal support roller for supporting the steel plate ring of the liquid hydrogen tank and a movable seat for mounting the horizontal support roller. Both ends of the horizontal support roller are connected to the support on the movable seat through bearings.

[0007] The horizontal adjustment mechanism includes a horizontal guide rail located at the top of the crossbeam, and a sliding groove at the bottom of the movable seat that slides in cooperation with the horizontal guide rail.

[0008] The technical problem to be solved by this utility model can also be achieved through the following technical solution: a vertically set fixed baffle is installed at one end of the crossbeam near the column.

[0009] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the horizontal support roller is provided with a steel inner roller and a rubber sleeve covering the steel inner roller.

[0010] The technical problem to be solved by this utility model can also be achieved by the following technical solution: the lifting mechanism includes a lifting seat and a drive cylinder for driving the lifting seat to move up and down. The cylinder body of the drive cylinder is fixed on the column, and the piston rod of the drive cylinder is connected to the lifting seat. The lifting seats on both sides of the drive cylinder are symmetrically provided with guide mechanisms to make the lifting seat move up and down stably.

[0011] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the column is provided with two vertically arranged guide rods, the lower end of each guide rod is provided with a flange structure that connects to the plate rolling machine frame, the upper ends of the two guide rods are connected by a connecting plate, and the lower ends of the guide rods are fixed to the plate rolling machine frame by the flange structure and bolts, symmetrically arranged on both sides of the lifting seat, and the lifting seat is provided with guide holes that cooperate with the guide rods.

[0012] The technical problem to be solved by this utility model can also be achieved through the following technical solution: at least two horizontal support rollers are provided, and the horizontal support rollers are arranged side by side along the axial direction of the crossbeam, preferably two or three.

[0013] Compared with existing technologies, this utility model provides support from within the liquid hydrogen tank steel plate ring by setting up a crossbeam and support frame. By setting up horizontal support rollers, the liquid hydrogen tank steel plate ring is rolled while rotating, which provides auxiliary support for the rolling machine while reducing the rotational intensity of the liquid hydrogen tank steel plate ring and improving the working efficiency of the rolling machine. By setting up a lifting mechanism, the height of the entire support frame can be adjusted according to the diameter of the liquid hydrogen tank steel plate ring to adapt to the rolling of liquid hydrogen tank steel plate rings of different sizes. Moreover, the entire device only requires a power unit at the lifting mechanism, resulting in low energy consumption. By setting up a horizontal adjustment mechanism, the position and number of horizontal support rollers can be adjusted according to the width of the liquid hydrogen tank steel plate ring to adapt to the rolling of liquid hydrogen tank steel plate rings of different widths.
