Description

Technical Field

[0001] This invention relates to the field of plate rolling machine technology, and in particular to an ultra-high upper support device for a plate rolling machine. Background Technology

[0002] In the fields of heavy machinery, pressure vessels, marine engineering, and wind power equipment manufacturing, the demand for rolling and forming large-diameter, thick-walled cylinders is increasing. For example, in the rolling process of large workpieces such as wind turbine towers (diameter 3-5m, wall thickness 20-50mm) and LNG storage tanks (diameter exceeding 10m), the support and stability of the upper roller of the plate rolling machine has become a key technical challenge. Traditional plate rolling machines, limited by structural height, are prone to problems such as upper roller sagging and vibration when processing ultra-large plates, leading to excessive roundness errors in the workpiece (e.g., target roundness ≤1mm / m, actual deviation reaches 3-5mm / m), seriously affecting the accuracy of subsequent welding and assembly. With the development of industrial equipment towards "larger and more precise" designs, higher requirements are placed on the load-bearing capacity, height adjustment range, and stability of the upper roller of the plate rolling machine.

[0003] In the use of traditional plate rolling machines, the upper support device typically uses a chain extension as the lifting structure. However, the chain extension cannot meet the lifting requirements of some heavy goods, resulting in a limited range of applications and reduced practicality of the device. Summary of the Invention

[0015] (III) Beneficial Effects

[0016] This invention provides an ultra-high upper support device for a plate rolling machine. It has the following advantages:

[0017] 1. Through the setting of the support arm and roller mechanism, the rotation of the auxiliary roller drives the support arm to move up and down on the support column, thereby adjusting according to the diameter of the plate. The rollers on the bracket provide auxiliary support for the outer surface of the plate, and the rotation of the rollers facilitates the efficiency of the plate during rolling. The setting of the ring wire rope hoist makes the device suitable for lifting some large goods. The wire rope is welded or pressed at both ends to form a closed loop. The friction between the drive wheel and the driven wheel drives the ring rope to circulate. The drive wheel drives the ring wire rope to rotate through friction. The lifting device suspended on the rope lifts and lowers with the movement of the rope. The hook is used to hook the goods, so that the wire rope is evenly stressed. The wire rope hoist is smaller in size than the traditional electric hoist, making it suitable for space-constrained applications.

[0018] 2. Through the setting of the support plate and through hole, the pin and rod can be used to make it pass through the through hole and fix it to the ground plane. The tie rod is set in a figure eight shape, which can anchor the support to the ground plane and prevent lateral force during rolling. The cooperation between the hinge seat and the tie rod allows the support and bracket to be adjusted according to the ground, improving the stability of the device. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] Example 1

[0027] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides an ultra-high type upper support device for a plate rolling machine, including a support column 3, a support plate 301 fixedly connected to the bottom end of the support column 3, a support arm 1 movably sleeved on the outer surface of the support column 3, a roller mechanism 2 movably arranged inside the support arm 1, a wire rope hoist 6 fixedly connected to the top end of the support column 3, and a wire rope 5 arranged inside the wire rope hoist 6. A pull rod 4 movably arranged on the outer surface of the support column 3.

[0028] The support arm 1 is arranged in an L-shape, and an auxiliary roller 101 is rotatably arranged between the inner walls of the support arm 1. The auxiliary roller 101 is slidably connected to the outer surface of the support column 3. The roller mechanism 2 includes a bracket 201 inserted inside the support arm 1, and a roller 203 is rotatably arranged on the top of the bracket 201.

[0029] Specifically, there are five rollers 203, and a hook 204 is fixedly connected to the top of the support arm 1 on the side away from the bracket 201. A rotating shaft 202 is rotatably provided on the inner wall of the support arm 1, and the bracket 201 is rotatably connected to the support arm 1 through the rotating shaft 202.

[0030] Furthermore, through the arrangement of the support arm 1 and the roller mechanism 2, the rotation of the auxiliary roller 101 causes the support arm 1 to move up and down on the support column 3, thereby adjusting according to the diameter of the plate. The roller 203 on the bracket 201 provides auxiliary support for the outer surface of the plate, and the rotation of the roller 203 facilitates the efficiency of the plate during rolling. The use of the annular wire rope hoist 6 makes the device suitable for lifting some large goods. The wire rope 5 is welded or pressed at both ends to form a closed loop. The friction between the drive wheel and the driven wheel drives the annular rope to circulate. The drive wheel drives the annular wire rope 5 to rotate circularly through friction. The hook 501, which is suspended on the rope, lifts and lowers with the movement of the rope. The hook 501 hooks the goods, so that the wire rope 5 is evenly stressed. The wire rope hoist 6 is smaller in size than the traditional electric hoist, making it suitable for space-constrained applications.

[0031] Example 2

[0032] Reference Figure 1 , Figure 3 and Figure 4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] A ring-shaped wire rope hoist 6 is fixedly connected to the top of the support column 3. A wire rope 5 is movably installed inside the ring-shaped wire rope hoist 6. A hook 501 is fixedly connected to the end of the wire rope 5 away from the ring-shaped wire rope hoist 6. A tie rod 4 is fixedly connected to one side of the top of the support column 3. A hinge seat 401 is hinged to the end of the tie rod 4 away from the support column 3. A support plate 402 is fixedly connected to the bottom of the hinge seat 401. Several through holes 403 are opened on the top of the support plate 402.

[0034] Specifically, the bottom of the support column 3 is fixedly connected to the base plate 301, and the top of the base plate 301 is provided with a fixing rod 302, which is used to fix the support column 3 to the ground plane. The steel wire rope 5 is made of multiple strands of fine steel wire, and the length of the tie rod 4 is greater than the length of the support column 3. The two tie rods 4 are arranged in a figure-eight shape.

[0035] Furthermore, through the setting of the support plate 402 and the through hole 403, the pin and the rod can be used to make it pass through the through hole 403 and be fixed to the ground plane. The tie rod 4 is set in a figure-eight shape, which can anchor the support column 3 to the ground plane and prevent lateral force during rolling. The hinge seat 401 and the tie rod 4 are used to adjust the support column 4 and the bracket 201 according to the ground, which improves the stability of the device.

[0036] Working Principle: During use, the support column 3 is fixed to the ground plane by the base plate 301 and the fixing rod 302. Through the setting of the support plate 402 and the through hole 403, the support column 3 is fixed to the ground plane by the cooperation of the pin and the pin rod. The tie rod 4, arranged in a V-shape, anchors the support column 3 to the ground plane, preventing lateral forces during rolling. The cooperation between the hinge seat 401 and the tie rod 4 allows the support column 4 and the bracket 201 to be adjusted according to the ground, improving the stability of the device. Through the setting of the support arm 1 and the roller mechanism 2, the rotation of the auxiliary roller 101 causes the support arm 1 to move up and down on the support column 3, thereby adjusting according to the diameter of the plate. The rollers 203 on the frame 201 provide auxiliary support for the outer surface of the sheet metal, and the rotation of the rollers 203 facilitates the efficiency of the sheet metal during rolling. The use of the annular wire rope hoist 6 makes the device suitable for lifting large goods. The wire rope 5 is welded or pressed at both ends to form a closed loop. The friction between the drive wheel and the driven wheel drives the annular rope to rotate. The hook 501, which is suspended on the rope, moves up and down with the movement of the rope. The hook 501 is used to hook the goods, so that the wire rope 5 is evenly stressed. The use of the wire rope hoist 6 makes it smaller than traditional electric hoists, making it suitable for space-constrained applications.
