Description

A roller conveyor device for upright tanks Technical Field

[0001] This utility model relates to the field of pressure vessel manufacturing technology, and in particular to a roller conveyor device for upright tanks. Background Technology

[0002] Large pressure vessel gas storage tanks are key equipment in petrochemical, energy storage and transportation fields. The safety, accuracy, and efficiency of their conveying and assembly processes directly affect the continuity of the production line. In the conveying and assembly process of large pressure vessel gas storage tanks, traditional roller conveyor devices can usually only achieve horizontal conveying of tanks, while vertical tank operation relies on manual operation and the coordination of multiple equipment (such as cranes and support frames). This is prone to tank tilting and collisions due to operational errors or improper equipment coordination. Minor issues may result in surface dents and coating peeling, while major issues may lead to structural deformation or even weld cracking. Furthermore, this method generally suffers from low efficiency and high labor intensity. To solve these problems, we propose a vertical tank roller conveyor device that integrates conveying, tilting, and protection functions to meet the urgent needs of modern industry for efficient assembly of large pressure vessels. Summary of the Invention

[0003] The purpose of this utility model is to provide a roller conveyor device for vertical tanks, so as to solve the problems of low efficiency and prominent safety hazards caused by the reliance on manual labor and multi-equipment coordination in the traditional vertical tank process.

[0004] To solve the above technical problems, this utility model provides a roller conveyor device for upright cans, including a roller conveyor. The roller conveyor is composed of two sets of parallel rollers arranged symmetrically and inclinedly to form a "V" shaped conveying surface, which is used to carry the transverse rolling conveyor of cylindrical cans. The spacing between the rollers is less than 1 / 2 of the can diameter.

[0005] The upright tank mechanism is located on both sides of the roller conveyor and includes a rotating shaft and fixed platforms located on both sides of the roller conveyor. The roller conveyor is driven by a telescopic rod to achieve a 1 / 4 arc tilt around the rotating shaft from horizontal to vertical.

[0006] The can-dropping rack includes multiple parallel rollers for supporting the tilted can.

[0007] A clamping mechanism is provided on the top of the can-dropping frame and includes a pressure plate, which is used to clamp the outer wall of the can after the can is upright.

[0008] Preferably, the telescopic adjustable support leg adopts a threaded sleeve structure, and the included angle between the conveying surfaces of the rollers is in the range of 120 degrees to 150 degrees.

[0009] Preferably, the roller conveyor is mounted on a base and supported by a fixed platform and a support frame.

[0010] Preferably, the telescopic rod is driven by a cylinder, with the cylinder body hinged to the base and the piston rod end hinged to the bottom of the roller conveyor.

[0011] Preferably, the base surface is also provided with guide rails disposed on both sides of the can rack.

[0012] Preferably, the clamping mechanism further includes sliding frames disposed on both sides of the pressure plate, and a screw rod disposed between the fixed platform and the sliding frames, wherein the bottom of the sliding frames cooperates with the guide rail.

[0013] Preferably, the pressure plate has a concave arc surface facing the roller conveyor, and the inner surface of the pressure plate is covered with an elastic buffer layer. The clamping and releasing of the pressure plate on the tank is achieved by a screw driven by a motor.

[0014] Compared with the prior art, the roller conveyor device for vertical tanks of this utility model realizes continuous automated operation of tanks from horizontal to vertical transport by setting up V-shaped roller conveyors and tilting mechanisms, without the need for manual intervention, which significantly improves the transportation and assembly efficiency of the production line. At the same time, the surface of the pressure plate is covered with an elastic buffer layer, combined with the arc structure, to avoid scratches and deformation to the outer wall of the tank during clamping, thus ensuring the integrity of the storage tank.

[0022] Example

[0023] This utility model provides a roller conveyor device for upright cans, as shown in Figures 1-3. It includes a roller conveyor 1, which consists of two sets of parallel rollers 101 arranged symmetrically and inclined to form a "V"-shaped conveying surface for the lateral rolling conveying of cylindrical cans. The spacing between the parallel rollers 101 is less than half the diameter of the can. A can-standing mechanism 2 is located on both sides of the roller conveyor 1 and includes a rotating shaft 201 and fixed platforms 202 located on both sides of the roller conveyor 1. The roller conveyor 1 is driven by a telescopic rod 203 to achieve a 1 / 4 arc tilt around the rotating shaft 201 from horizontal to vertical. A can-dropping frame 3 includes multiple parallel rollers 301 for supporting the tilted can. A clamping mechanism 4 is located at the top of the can-dropping frame 3 and includes a pressure plate 401 for clamping the outer wall of the can after it is upright.

[0024] The included angle between the axes of the relative rollers 101 is between 120 and 150 degrees; the roller conveyor 1 is mounted on the base 5 and supported by the fixed platform 202 and the support frame 501; the telescopic rod 203 is driven by a cylinder, the cylinder body is hinged to the base 5, and the end of the piston rod is hinged to the bottom of the roller conveyor 1; the surface of the base 5 is also provided with guide rails 502 on both sides of the can dropping frame 3; the pressing mechanism 4 also includes sliding frames 402 on both sides of the pressure plate 401, and a screw 403 between the fixed platform 202 and the sliding frames 402, the bottom of the sliding frames 402 cooperating with the guide rails 502; the pressure plate 401 has a concave arc surface towards the roller conveyor 1, the inner surface of the pressure plate 401 is covered with an elastic buffer layer, and the pressure plate 401 clamps and releases the can by driving the screw 403 through the motor 404.

[0025] It should be noted that the roller conveyor 1 consists of two sets of parallel rollers 101 arranged symmetrically and inclined to form a 120-degree V-shaped conveying surface. The V-shaped structure makes the tank roll along the axis, avoiding deviation. It is especially suitable for slender tanks with a length-to-diameter ratio ≥2. The surface of the rollers 101 is coated with black zinc to reduce the coefficient of friction and reduce surface scratches when the tank rolls. The extended axis of each set of rollers 101 intersects the center line of the roller conveyor 1, forming a self-centering structure.

[0026] Preferably, the roller conveyor 1 is supported on the base 5 by the fixed platform 202. The roller conveyor 1 rotates around the fixed platform 202 by the rotating shaft 201. There is a pair of support frames 501, just like the fixed platform 202. The support frames 501 are welded to the base 5. When the tank is transported horizontally, the support frames 501 are used to support the other end of the roller conveyor 1 relative to the fixed platform 202. The roller conveyor 1 and the support frames 501 are supported by abutting each other.

[0027] Preferably, the rotating shaft 201 passes through both sides of the roller conveyor 1 and is hinged to the fixed platform 202. The cylinder of the telescopic rod 203 is connected to the base 5 through the hinge seat. The end of the piston rod is hinged to the bottom of the roller conveyor 1. After the cylinder is started, the telescopic rods 203 on both sides retract synchronously, driving the roller conveyor 1 to rotate 90° around the rotating shaft 201, causing the tank to tilt from a horizontal state to a vertical state. The center of gravity of the rotating shaft 201 coincides with that of the roller conveyor 1, ensuring that there is no slippage when the tank tilts.

[0028] Preferably, the can drop frame 3 is located below the end of the roller conveyor 1 and consists of multiple parallel rollers 301. The surface of the rollers is covered with a 3mm thick polyurethane layer. The polyurethane layer absorbs the impact of the can sliding down and avoids surface damage caused by metal collision. The rollers 301 roll with the weight of the can and automatically compensate for the position deviation of the can after tilting.

[0029] Preferably, the pressure plate 401 has a concave arc surface that matches the outer wall of the tank, and a 10mm thick silicone buffer layer is attached to the inner surface. The bottom of the sliding frame 402 is provided with a sliding groove, which cooperates with the guide rail 502 of the base 5 to ensure horizontal movement accuracy. The motor 404 drives the screw 403 to rotate, which drives the sliding frame 402 to move along the rail 502, so that the pressure plate 401 clamps or releases the tank.

[0030] In summary, the roller conveyor device for vertical tanks in this embodiment, by setting up a V-shaped roller conveyor and a tilting mechanism, enables continuous automated operation of the tank from horizontal transport to vertical erection, without the need for manual intervention. This significantly improves the transportation and assembly efficiency of the production line. At the same time, the surface of the pressure plate is covered with an elastic buffer layer, combined with the arc structure, to avoid scratches and deformation to the outer wall of the tank during clamping, ensuring the integrity of the storage tank. This device has been successfully applied to the production of large double-walled high-pressure storage tanks in aerial transport lines, and the efficiency of erecting tanks is greatly improved compared to traditional manual or crane methods.

[0031] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
