[0002] During heat treatment, the outside of the equipment cylinder is supported by a saddle and the inside is equipped with supporting fixtures to prevent the equipment from deforming due to heat treatment.

[0003] At present, ordinary 20# and 16Mn carbon steel pipes are mostly used to support the inside of the cylinder. Each time a heat treatment is performed, a lot of materials are used, which is inconvenient to disassemble and consumes supporting tooling. Summary of the invention

[0004] In order to facilitate the recycling of supporting tooling and reduce the heat treatment cost of the equipment barrel, the present invention provides internal supporting tooling and a supporting method for heat treatment equipment.

[0005] The internal support tooling and support method of the heat treatment equipment provided by the present invention adopt the following technical solutions:

[0006] The internal support tooling of the heat treatment equipment includes a cylinder, a self-assembled support and an automatic support. The self-assembled support and the automatic support are both clamped in the interior of the cylinder at a time-sharing manner. The self-assembled support includes a support tube and a support end. The support tube is clamped in the interior of the cylinder through the support end; the automatic support includes a controller and a center column. The top end of the center column is rotatably connected to six flip rods, and one end of each of the flip rods is fixedly connected to a time-sharing opening and closing fan leaf mechanism.

[0007] By adopting the above technical solution, both the self-assembled support and the automatic support can be supported inside the cylinder to prevent the cylinder from being deformed due to heat treatment. Both the self-assembled support and the automatic support can be disassembled, which is convenient for recycling in different cylinders.

[0008] Preferably, the support tube comprises several steel tubes of different lengths, each of which is fixedly connected to flanges at both ends, wherein in a part of the flanges, each two corresponding flanges are connected to each other by bolts, and arc plates are fixedly connected to the outer surfaces of the corresponding two steel tubes.

[0009] By adopting the above technical solution, the flange is used to facilitate the assembly and disassembly of steel pipes of different lengths, so that support pipes of various lengths can be formed between the steel pipes to support cylinders of different diameters. The arc plate allows different support pipes to support each other, making the support of multiple support pipes integrated.

[0010] Preferably, the supporting end includes a gasket and a pad block, the inner side of each gasket is fixedly connected to the outer side of the pad block, the outer side of each gasket is clamped to the inner wall of the cylinder, the inner side of each pad block is provided with a groove matching the flange, and one end of another part of the flange is clamped to the inside of the corresponding groove.

[0011] By adopting the above technical solution, the gasket fits perfectly with the curvature of the cylinder and has a moderate length. After being connected to the support tube, the supporting force is also moderate, avoiding excessive local supporting force. During the heat treatment process, bulges appear at the supporting part, affecting the roundness of the cylinder.

[0012] Preferably, the outer surface of the central column is rotatably connected to six inclined rods, and the top of the central column is fixedly connected to six motors. The end of each motor output shaft is transmission-connected to one end of the corresponding flip rod, and a slide groove is provided at the bottom of each flip rod, and the other end of each inclined rod is slidably connected to the inside of the corresponding slide groove.

[0013] By adopting the above technical solution, a triangle is formed between the oblique rod, the central column and the flip rod. When the flip rod is reversed, the oblique rod enhances the stability of the flip rod.

[0014] Preferably, the top of each flip rod is fixedly connected to a hydraulic cylinder 1, the end of each hydraulic cylinder 1 is transmission-connected to a positioning plate, the interior of each positioning plate is fixedly connected to a displacement sensor, each displacement sensor and each motor is communicatively connected to a controller, and through holes are provided at both ends of each positioning plate.

[0015] By adopting the above technical solution, the hydraulic cylinder drives the time-sharing opening and closing fan leaf mechanism to move along the length direction of the flip rod, so that the distance between the time-sharing opening and closing fan leaf mechanism and the center column changes, and then when the arc-shaped fan leaf is unfolded, it adapts to cylinders of different diameters.

[0016] Preferably, each of the time-sharing opening and closing fan leaf mechanisms includes a stretching rod, two hydraulic cylinders 2 and two arc-shaped fan leaves, and every two corresponding hydraulic cylinders 2 and every two corresponding arc-shaped fan leaves are symmetrically distributed and are respectively located on both sides of the corresponding stretching rod, one end of the two arc-shaped fan leaves is rotatably connected to the end of the stretching rod away from the hydraulic cylinder 1, and the end of the output shaft of each hydraulic cylinder 2 is fixedly connected to the other end of the corresponding arc-shaped fan leaf.

[0017] By adopting the above technical solution, the arc-shaped fan leaves are opened and closed by the stretching of the second hydraulic cylinder. When the arc-shaped fan leaves are fully unfolded, a circular ring is formed to support the inner wall of the cylinder. After the support is completed, the arc-shaped fan leaves are closed to facilitate removal from the interior of the cylinder.

[0021] By adopting the above technical solution, when the diameter of the cylinder is large enough that workers can install it without setting up a work ladder, self-assembled support can be used for manual installation. When the diameter of the cylinder is too large, automatic support can be used to ensure human safety. It is safe and fast. Self-assembled support and automatic support are based on the size of the pipe diameter, and workers can judge and install them by themselves.

[0022] Preferably, in step B, the specific operation steps of assembling the self-assembled support include selecting steel pipes of appropriate lengths, connecting the flange ends of different steel pipes to the gaskets and the corresponding flanges respectively through bolts, and welding arc plates on the corresponding two cross-shaped steel pipes; in step C, the specific operation steps of disassembling the self-assembled support include removing the bolts, separating the gaskets and the flanges, and separating the flanges of the two steel pipes.

[0023] By adopting the above technical scheme, the flange is connected by bolts, which is quick to install and disassemble, saving time and effort. It is only used at the intersection and is firmly welded with arc plates, that is, arc-shaped steel strips. It is convenient to reduce the amount of seamless steel pipes, pads, and arc plates.

[0026] In summary, the present invention has the following beneficial technical effects:

[0027] 1. The present invention is provided with a self-assembled support, and the flange is connected by bolts, so that support pipes of various lengths can be formed between the steel pipes, which are suitable for supporting cylinders of different diameters.

[0047] The following is combined with the accompanying drawings Figure 1-Figure 10 The present invention is described in further detail.

[0048] The embodiment of the present invention discloses an internal support tooling for heat treatment equipment.

[0049] Reference Figure 1 , Figure 5 , Figure 6 , including a cylinder 1, a self-assembled support and an automatic support. The cylinder 1 includes a cylinder section without a head and a cylinder section with a head. The cylinder section without a head at the end is provided with a group of support pipes at the open part, that is, a vertical support, two vertical supports in a square shape and two cross-crossed oblique pipe supports. The support pipe groups are evenly arranged at a certain distance inside the cylinder 1 to avoid the weld of the cylinder 1. For the cylinder section without a head at the end, the head has a reinforcing effect on the cylinder 1, and the head end can reduce a group of support pipe groups. The self-assembled support and the automatic support are evenly connected to the inside of the cylinder 1. The self-assembled support It includes a support tube and a support end, and the support tube is clamped to the inside of the cylinder 1 through the support end; the automatic support includes a controller and a center column 2, and the automatic support and the cylinder 1 are both located above the large-stroke mobile base. The automatic support is clamped and extended into the inside of the cylinder 1 through a mechanical arm and a clamp. When installed, the center column 2 is located on the coaxial line of the cylinder 1. The top of the center column 2 is rotatably connected to six flip rods 3. Driven by the motor 12, the flip rod 3 rotates upward to close, and rotates downward to spread. One end of each flip rod 3 is fixedly connected to a time-sharing opening and closing fan leaf mechanism 4.

[0050] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5The support pipe includes several steel pipes of different lengths. S30408 ​​steel pipes and steel plates are selected as heat treatment support materials for carbon steel and low alloy steel equipment. When the heat treatment reaches 700°C and the allowable stress is above 10Mpa, it can still meet the support requirements. The end of each short section of steel pipe is welded with a plate flat welding flange 7, which is connected with ordinary carbon steel bolts during support to form a whole support pipe. Both ends of each steel pipe are fixedly connected with flanges 7. In some of the flanges 7, each two corresponding flanges 7 are connected by bolts, and the outer surfaces of the corresponding two steel pipes are fixedly connected with arc plates 8.

[0051] Reference Figure 2 , Figure 3 , Figure 4 The supporting end includes a gasket 5 and a pad 6. The arc-shaped support length of the gasket 5 reaches a certain ratio to avoid excessive local supporting force. During the heat treatment process, bulges appear at the supporting position, affecting the roundness of the cylinder 1 and avoiding the support becoming a weak area of ​​the pressure vessel. The inner side of each gasket 5 is fixedly connected to the outer side of the pad 6, and the outer side of each gasket 5 is clamped on the inner wall of the cylinder 1. The inner side of each pad 6 is provided with a groove compatible with the flange 7, and one end of the other part of the flange 7 is clamped in the corresponding groove. A support tube is erected in the cylinder 1, and on one side of the support tube, two vertical support tubes in a square are connected to the cylinder 1, and there are oblique support tubes at the diagonal of the inscribed square, which is convenient for the cylinder 1 to support uniformly and bear uniform force.

[0052] Reference Figure 6 , Figure 7 , Fig. 9 The outer surface of the central column 2 is rotatably connected with six inclined rods 9, and the top of the central column 2 is fixedly connected with six motors 12. The end of the output shaft of each motor 12 is transmission-connected to one end of the corresponding flip rod 3. A slide groove is provided at the bottom of each flip rod 3, and the other end of each inclined rod 9 is slidably connected to the inside of the corresponding slide groove. The motor 12 drives the flip rod 3 to rotate, so that the time-sharing opening and closing fan page mechanism 4 is dispersed or aggregated. The dispersed time-sharing opening and closing fan page mechanism 4 can unfold the arc fan page 43 through the hydraulic cylinder 2 42. After the heat treatment is completed, the arc fan page 43 is closed back to the two sides of the stretching rod 41.

[0053] Reference Figure 6 , Figure 7 , Figure 8, the top of each flip rod 3 is fixedly connected with a hydraulic cylinder 10, and the hydraulic cylinder 10 drives the positioning plate 11 to move away from or close to the center column 2, and then the hydraulic cylinder 10 drives the time-sharing opening and closing fan leaf mechanism 4 to move away from or close to the center column 2. The end of each hydraulic cylinder 10 is transmission-connected with a positioning plate 11, and the hydraulic cylinder 2 42 rotates on the outer surface of the positioning plate 11 through the rotating ring 13, so as to facilitate the closing of the arc fan leaf 43. A displacement sensor is fixedly connected to the inside of each positioning plate 11, and the displacement sensor monitors the position of the positioning plate 11 in real time, so that the rotation angle and linear movement distance of the positioning plate 11 can be transmitted to the controller in real time. The worker can connect the corresponding display through the controller to view the current flip angle of the flip rod 3 and the distance between the time-sharing opening and closing fan leaf mechanism and the center column 2 in real time. Each displacement sensor and each motor 12 are communicatively connected to the controller, and through holes are opened at both ends of each positioning plate 11.

[0054] Reference Figure 6 , Figure 7 , Figure 8 Each time-sharing opening and closing sash mechanism 4 includes a stretching rod 41, two hydraulic cylinders 42 and two arc-shaped sashes 43. When the hydraulic cylinder 42 drives the arc-shaped sash 43 to rotate, the stretching rod 41 is used to synchronize the rotation of the arc-shaped sash 43. After the arc-shaped sash 43 is unfolded, the distance from the baffle 14 to the central column 2 is much greater than the length of the flip rod 3. The time-sharing opening and closing sash mechanism 4 is located above the flip rod 3. The rotating end of the flip rod 3 is connected to the hydraulic cylinder 10. Every two corresponding hydraulic cylinders 42 and every two corresponding hydraulic cylinders 42 are connected to each other. The corresponding arc-shaped fan leaves 43 are symmetrically distributed and are respectively located on both sides of the corresponding stretching rod 41. One end of the two arc-shaped fan leaves 43 is rotatably connected to the end of the stretching rod 41 away from the hydraulic cylinder 10. The end of the output shaft of each hydraulic cylinder 42 is fixedly connected to the other end of the corresponding arc-shaped fan leaf 43. One end of the arc-shaped fan leaf 43 is rotated on one end of the stretching rod 41. Therefore, when the hydraulic cylinder 42 drives the other end of the arc-shaped fan leaf 43 to move, the arc-shaped fan leaf 43 performs a circular motion around the stretching rod 41.

[0055] Reference Figure 6 , Figure 8 , Fig.10One end of each stretching rod 41 is fixedly connected to one side of the corresponding positioning plate 11, and the other end of each positioning plate 11 is fixedly connected to a baffle 14. One side of each hydraulic cylinder 42 is fixedly connected to a rotating ring 13, and each rotating ring 13 is plugged into the inside of the corresponding through hole. Each baffle 14 and the outer side of each arc-shaped fan leaf 43 are fixedly connected to a heat insulation layer, which blocks heat transfer and protects various mechanical devices and electrical parts in the automatic support. A pressure sensor is fixedly connected to the inside of each baffle 14. Each pressure sensor, each hydraulic cylinder 10 and each hydraulic cylinder Both hydraulic cylinders 10 and 42 are connected to the controller for communication. The controller can control the opening and closing of each pressure sensor, each hydraulic cylinder 10 and each hydraulic cylinder 2 42. After the worker inputs the diameter data of the cylinder 1, the controller controls the distance of the time-sharing opening and closing fan leaf mechanism 4 away from the center column 2 according to the data of the displacement sensor and the pressure sensor. When the baffle 14 is in contact with the inner wall of the cylinder 1, the pressure sensor transmits the corresponding value, and the controller controls the hydraulic cylinder 2 42 to drive the arc-shaped fan leaves 43 to rotate, so that all the arc-shaped fan leaves 43 are in close contact with the inner wall of the cylinder 1, and automatically support the inner wall of the cylinder 1.

[0056] The embodiment of the present invention also includes a method for supporting internal tooling of heat treatment equipment.

[0057] Reference Figure 5 , Figure 6 , Figure 7 , including the following operating steps: step A, according to the size of the cylinder 1, when the cylinder 1 is small, it is more appropriate to use the existing matching support tube, and select appropriate self-assembly support and automatic support; step B, assemble the self-assembly support and turn on the automatic support; step C, disassemble the self-assembly support and automatic support.

[0058] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5In step B, the specific operation steps of assembling the self-assembled support include selecting steel pipes of appropriate lengths, assembling steel pipes of different lengths according to the diameter of the hot-processed pipe, and then forming a support pipe with a length that matches the pipe diameter, and connecting the flange 7 ends of different steel pipes to the pad 6 and the corresponding flange 7 respectively through bolts. On the corresponding two cross-shaped steel pipes, the cross-shaped steel pipes are firmly welded by arc-shaped steel strips to make the support seamless, and the arc plate 8 is welded, and the arc plate 8 is the arc-shaped steel strip; in step C, the specific operation steps of disassembling the self-assembled support include removing the bolts, separating the pad 6 and the flange 7, and separating the flanges 7 of the two steel pipes. During disassembly, the worker removes the bolts through the tool, and first separates the pad 6 and the corresponding flange 7. If the next cylinder 1 is of the same size, the steel pipe does not need to be disassembled. If the next cylinder 1 is of a different size, the steel pipe can continue to be disassembled until it is disassembled into the smallest unit. When encountering the next cylinder 1 of a different size, the support pipe of the appropriate size is reassembled, which is convenient for repeated use in equipment of different diameters.

[0059] Reference Figure 6 , Figure 7 , Figure 8 In step B, the specific operation steps of opening the automatic support include starting the motor 12, and the six motors 12 drive the corresponding flip rods 3 to rotate downward. During the rotation of the flip rod 3, the positioning plate 11 and the time-sharing opening and closing fan leaf mechanism 4 are driven to rotate together, and the displacement sensor moves and the pressure sensor rotates together. After the displacement sensor moves to a suitable position, the motor 12 is stopped, and the displacement sensor and the pressure sensor transmit data to the controller in real time. The controller calculates the current position of the positioning plate 11 through the transmitted data. When the positioning plate 11 rotates to a suitable position, that is, the baffle 14 is against the inner wall of the cylinder 1, the controller controls the motor 12 to stop rotating and controls the hydraulic cylinder 1 10 to stop working. At this time, the distance between the baffle 14 and the center column 2 is equal to the radius of the inner wall of the cylinder 1. The hydraulic cylinder 10 and the hydraulic cylinder 2 42 are started to open and close in time. The fan leaf mechanism 4 moves in the direction away from the center column 2, and the two arc-shaped fan leaves 43 are unfolded to the sides away from the flip rod 3 until the baffle 14 touches the inner wall of the cylinder 1, and the hydraulic cylinder 1 10 and the hydraulic cylinder 2 42 are stopped; in step C, the specific operation steps of disassembling the automatic support include starting the hydraulic cylinder 10 and the hydraulic cylinder 2 42, the time-sharing opening and closing fan leaf mechanism 4 moves in the direction close to the center column 2, and the two arc-shaped fan leaves 43 are recovered to the sides of the return flip rod 3, and the motor 12 is started. The six motors 12 drive the corresponding flip rods 3 to rotate upward, and the hydraulic cylinder 2 42 pulls one end of the arc-shaped fan leaf 43 to make the arc-shaped fan leaf 43 do a 1 / 4 circle motion around the baffle 14. After the arc-shaped fan leaves 43 of the six time-sharing opening and closing fan leaf mechanisms 4 are fully unfolded, they cooperate with the baffle 14, and the outer side of the arc-shaped fan leaf 43 is completely in contact with the inner wall of the cylinder 1.

[0060] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
