Description

TECHNICAL FIELD

[0001] The present application relates to the field of pressure vessel processing auxiliary equipment, in particular to a pressure vessel anti-deformation heat treatment supporting device. BACKGROUND

[0002] As a key equipment for bearing pressure and medium, pressure vessels are widely used in chemical industry, energy, pharmaceutical industry and other fields. In its manufacturing process, especially after welding forming, strict heat treatment is usually needed to eliminate welding residual stress, improve weld structure, prevent stress corrosion and deformation, so as to ensure the structural stability and operation safety of the vessel. Heat treatment is usually carried out in a large heat treatment furnace or by local heating, and during this process, the pressure vessel weighing several tons or even dozens of tons must be stably supported. Therefore, a pressure vessel heat treatment supporting device with reasonable structure, strong carrying capacity and capable of adapting to different process requirements is crucial to ensure the heat treatment quality and prevent secondary deformation of the vessel at high temperature.

[0003] In the prior art, the heat treatment supporting device for such large workpieces has a relatively traditional mechanical structure. These devices usually adopt fixed frame or saddle structure welded from heavy steel. In terms of function, in order to facilitate the placement of the pressure vessel, some supports are provided with simple rollers or balls at the supporting points, and after the workpiece is hoisted into place by a crane, the position is adjusted by the rollers. In some other solutions requiring high stability, fixed V-shaped blocks or arc-shaped supporting pads matching the shape of the vessel are used, and the workpiece is directly placed on these fixed supports. The entire supporting system is a rigid structure with integral welding or large bolt assembly structure, and has single function, mainly playing a passive supporting role.

[0004] However, the above prior art has exposed a series of problems in actual application scenarios:

[0005] Firstly, many supporting devices adopt integral welding or complex bolt assembly structure, resulting in large size and fixed structure. This makes it very difficult to install the device for the first time, to move it later or to adjust it according to pressure vessels of different sizes, and the transportation and installation cost is high, and it is difficult to flexibly adapt to the changing production site requirements.

[0006] Secondly, there is an inherent contradiction between "convenient positioning" and "stable support" in the device. If roller type support is adopted to facilitate position adjustment, there is a risk of slipping or rolling of the vessel under high temperature and self-weight during the heat treatment process lasting for several hours, affecting the treatment effect and even causing safety hazards. On the contrary, if fixed anti-slip support blocks are adopted, although stability is ensured, it is difficult for the operator to accurately adjust the position when placing the heavy pressure vessel for the first time, and often needs to rely on the crane to hoist repeatedly or use a crowbar to forcibly calibrate, which is extremely labor-intensive and easy to scratch the surface of the vessel.

[0007] Finally, the existing support device function is passive, lacking auxiliary positioning capability, and when a large pressure vessel is hoisted near the support frame, the final "push in" and "alignment" steps completely rely on manual operation. Due to the huge weight and inertia of the container, manual pushing is not only inefficient, but also difficult to achieve precise control, increasing the safety risk and time cost of the operation. Therefore, the present application provides a pressure vessel anti-deformation heat treatment support device to solve the problems existing in the prior art. SUMMARY

[0034] Two air cylinders 7 are installed in the interior of the main bracket 1, the output end of the air cylinder 7 is fixedly connected with a limiting supporting block 8, one side of one of the mounting frames 501 is provided with a second motor 513, the output end of the second motor 513 is fixedly connected with a winding rod 514, the outer side of the winding rod 514 is fixedly connected with a pull rope 517, the proximal side of the mounting frame 501 without the first motor 503 is fixedly connected with a fixed rod 515, the outer middle side of the fixed rod 515 is rotatably connected with a second guide wheel 516, the outer side of the winding rod 514 is slidably connected with the outer sides of the first guide wheel 512 and the second guide wheel 516, the bottom of the main bracket 1 is provided with a push-pull mechanism 6, the push-pull mechanism 6 comprises two L-shaped rods 601, the L-shaped rod 601 is slidably connected to the bottom of the main bracket 1, the bottom of the main bracket 1 is fixedly connected with two U-shaped plates 603, the outer side of the L-shaped rod 601 is slidably connected with the inner side of the U-shaped plate 603, one end of the two L-shaped rods 601 is fixedly connected with a connecting rod 602, the outer side of the connecting rod 602 is fixedly connected with one end of the pull rope 517, the interior of the L-shaped rod 601 is provided with an electric push rod, and the output end of the electric push rod is fixedly connected with a sliding block 606, the outer side of the L-shaped rod 601 is provided with a sliding groove 607, the outer side of the sliding block 606 is slidably connected to the inner side of the sliding groove 607, the proximal side of the two sliding blocks 606 is fixedly connected with a movable frame 604, the outer side of the movable frame 604 is fixedly connected with a connecting cover 605.

[0035] Specifically, the device is composed of two main brackets 1 and a connecting frame 2 for connecting them to form a whole supporting platform. In the non-working state, the two main brackets 1 and the connecting frame 2 can be separated and stored. When assembling is needed, the two main brackets 1 are respectively moved from the left and right sides of the connecting frame 2 to approach it, so that the combined hook blocks 11 fixedly connected on the left and right sides of the connecting frame 2 are aligned and inserted into the movable grooves 401 opened on the side walls of the main brackets 1. Before insertion, the operator can hold the handle 403 passing through the through hole of the side wall of the main bracket 1, and lift the clamping block 402 slidingly connected inside the movable groove 401 upward to leave space for the combined hook block 11. When the combined hook block 11 completely enters the movable groove 401, the handle 403 is loosened, and the clamping block 402 falls under the action of its own gravity, and the outer side thereof is attached to the outer side of the combined hook block 11, so as to clamp the combined hook block 11, realizing the quick and stable splicing between the main bracket 1 and the connecting frame 2. The reserved groove 10 at the top of the connecting frame 2 provides a convenient operation space for various operations in the heat treatment process. The bottom of the main bracket 1 and the connecting frame 2 is connected with a supporting leg 3 through welding or bolt connection to ensure the stability of the whole device.

[0036] When the pressure container is placed and positioned, first, start the first motor 503 installed on one of the installation frames 501. The output shaft of the first motor 503 is connected with a rotating rod 502 through a shaft coupling. The two rotating rods 502 are connected in transmission through two belt pulleys 504 fixed on the corresponding positions of the two rods and a belt sleeved thereon, so as to ensure that the two rotating rods 502 can rotate synchronously. The outer side of each rotating rod 502 is fixedly connected with two cylindrical gears 506. Each cylindrical gear 506 is engaged with a rack plate 507 vertically arranged and slidingly connected inside the installation frame 501. Since the two cylindrical gears 506 on the same rotating rod 502 drive the two rack plates 507 located on the opposite sides of the gear, when the rotating rod 502 rotates, the two rack plates 507 will move up and down in opposite directions.

[0037] For example, when the first motor 503 is rotating forward, one of the rack plates 507 can be moved upward, and the supporting plate 509 fixedly connected to the top of the rack plate 507 is lifted, and the two circular platform rollers 511 rotatingly connected to the supporting plate 509 are lifted out of the opening slot 9 in the top of the main bracket 1 and above the upper surface of the main bracket 1. At this time, the other rack plate 507 is moved downward, and the supporting plate 509 and the anti-skid pad 510 fixedly connected to the top of the supporting plate 509 are lowered into the opening slot 9. Then, the cylinder 7 installed in the main bracket 1 is started, and the output end of the cylinder 7 pushes the limiting block 8 to move horizontally to the position below the supporting plate 509, and the limiting block 8 and the guide rail structure in the main bracket 1 provide a rigid support for the supporting plate 509 to bear the great weight of the subsequent pressure container. At this time, the pressure container can be placed on the two groups of lifted circular platform rollers 511. Since the circular platform rollers 511 can rotate freely, the operator can conveniently move and adjust the position of the pressure container with small force.

[0038] When the pressure container is adjusted to the position, the first motor 503 is reversed to rotate, the original supporting plate 509 with the circular platform rollers 511 is lowered and retracted into the opening slot 9. At the same time, the original supporting plate 509 with the anti-skid pad 510 is lifted from the opening slot 9 and supports the bottom of the pressure container. The anti-skid pad 510 increases the friction force of the contact surface, ensures that the pressure container does not slide during the heat treatment process, and ensures the stability of the placement. During the lifting process, the limiting block 508 fixedly connected to the side of the cylindrical gear 506 without gear teeth slides in the limiting slot 505 in the side wall of the mounting frame 501, which ensures that the cylindrical gear 506 does not axially move during rotation and ensures the stable engagement of the cylindrical gear 506 and the rack plate 507.

[0039] In addition, the device is also provided with a push-pull mechanism 6 to assist in pushing the pressure vessel. The mechanism is driven by a second motor 513 mounted on a mounting frame 501, starting the second motor 513, the output end of which drives the winding rod 514 to rotate, winding the pull rope 517 fixedly connected thereto, one end of the pull rope 517 being fixedly connected to the connecting rod 602 connecting the two L-shaped rods 601. The path of the pull rope 517 is specially designed: it is drawn out from the winding rod 514, passes around the first guide wheel 512 rotatingly connected to the outer middle side of one of the rotating rods 502, passes around the second guide wheel 516 rotatingly connected to the outer middle side of the fixed rod 515, and is finally connected to the connecting rod 602. Such a guide path enables one motor to simultaneously pull the push-pull mechanism 6 located at the bottom of the two main body brackets 1. When the pull rope 517 is tightened, it will pull the connecting rod 602, thereby driving the two L-shaped rods 601 to slide in the U-shaped plate 603 at the bottom of the main body bracket 1. At the same time, the electric push rod mounted inside the L-shaped rod 601 is started, the output end of which pushes the sliding block 606 to move in the sliding groove 607 outside the L-shaped rod 601. The proximal sides of the two sliding blocks 606 are fixedly connected with the movable frame 604, and the movable frame 604 is further fixedly provided with the connecting cover 605 outside, which together form a mesh cover frame structure. The extension of the electric push rod can make the mesh cover frame move upward, providing auxiliary pushing force to the side wall or bottom of the pressure vessel. According to actual needs, the second motor 513 and its winding rod 514 can also be mounted to the bottom of the connecting frame 2, which can optimize the structural layout and save energy consumption.

[0040] Working principle: the top of two main brackets 1 is used to place the pressure container for heat treatment, the connecting frame 2 is used to connect the two main brackets 1, the reserved groove 10 opened at the top of the connecting frame 2 is reserved space for heat treatment operation, when splicing is needed, the two main brackets 1 can be moved towards the connecting frame 2, so that the combined hook block 11 is inserted into the movable slot 401, before this, the handle 403 can be grabbed to lift the clamping block 402, when the combined hook block 11 completely enters the inside of the movable slot 401, the clamping block 402 is lowered to clamp the combined hook block 11, so that the main bracket 1 and the connecting frame 2 are stably connected; the first motor 503 is started to drive the rotating rod 502 to rotate, under the cooperation of the two pulleys 504 and the belt, the other rotating rod 502 is synchronously rotated, so that the cylindrical gear 506 drives the two rack plates 507 engaged with it to move staggeredly, the left rack plate 507 can be moved upwards, so that the supporting plate 509 drives the circular table roller 511 to move from the open slot 9 to the top of the main bracket 1, then the cylinder 7 is started to push the limiting supporting block 8 to move to the lower side of the supporting plate 509 to support it, the limiting supporting block 8 cooperates with the channel to bear the weight of the pressure container, at this time, the pressure container is placed on the main bracket 1, the circular table roller 511 can be used to move conveniently, when the movement is completed, the first motor 503 can be reversed to make the circular table roller 511 move downwards, so that the anti-skid pad 510 moves upwards to support the pressure container and increase the friction, so as to ensure that the pressure container is placed stably; in addition, the second motor 513 can be started to rotate the winding rod 514 and wind the pull rope 517, under the guidance of the first guide wheel 512 and the second guide wheel 516, the connecting rod 602 is driven to move, so that the L-shaped rod 601 is pulled to move, the electric push rod in the L-shaped rod 601 can make the mesh cover frame composed of the movable frame 604 and the connecting cover 605 move upwards to assist pushing the pressure container, and the second motor 513 on the mounting frame 501 can be mounted to the bottom of the connecting frame 2, so that the energy consumption of a second motor 513 can be saved, which can be set according to actual needs.
