Description

Technical Field

[0001] The utility model relates to the technical field of flange repair, in particular to a flange repair device. Background Art

[0002] Flange, also called flange flange or flange, is a part that connects shafts to each other and is used to connect pipe ends. It is also used on the inlet and outlet of equipment to connect two devices, such as reducer flange. Flange connection or flange joint refers to a detachable connection that is connected by flange, gasket and bolts as a combined sealing structure. Pipe flange refers to the flange used for piping in pipeline installations. When used on equipment, it refers to the inlet and outlet flanges of the equipment.

[0003] Flanges may rust after being used for a period of time, and the mechanical strength and sealing performance of rusted flanges will decrease. At this time, operators usually need to grind and remove rust from the rusted surface of the flange to ensure that the flange can achieve the predetermined connection and sealing effect. When removing rust, grinding wheels or files are mostly used for the operation.

[0004] The existing rust removal device needs to be fixed when the flange is being rusted, but the existing fixing method is relatively cumbersome, which results in a lot of time wasted in disassembling and replacing the flange with a new workpiece after the rust removal of a large number of flanges is completed, thus affecting the work efficiency.

[0028] Flange, also called flange flange or flange, is a part that connects shafts to each other and is used to connect pipe ends. It is also used on the inlet and outlet of equipment to connect two devices, such as reducer flange. Flange connection or flange joint refers to a detachable connection that is connected by flange, gasket and bolts as a combined sealing structure. Pipe flange refers to the flange used for piping in pipeline installations. When used on equipment, it refers to the inlet and outlet flanges of the equipment.

[0029] In the related art, the flange may rust after being used for a period of time, and the mechanical strength and sealing performance of the rusted flange will decrease. At this time, the operator is usually required to grind and remove the rust on the rusted surface of the flange to ensure that the flange can achieve the predetermined connection and sealing effect. When removing the rust, grinding wheels or files are mostly used for the operation.

[0030] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a flange repair device. When it is needed, the flange 19 to be repaired only needs to be put on the outside of the support rod 171, and then the hydraulic rod 18 is started to fix the flange 19, and then the flange 19 is rust-removed and repaired through the rust removal mechanism 13. After one group of flanges 19 is repaired, the motor 15 is started to drive the support plate 17 to rotate, so that the next group of flanges 19 can be rotated to the bottom of the rust removal mechanism 13, and the next group of flanges 19 can be rust-removed. In this way, the next group of flanges 19 can be rust-removed and repaired while the flanges 19 are disassembled and assembled, thereby increasing the working efficiency.

[0031] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0032] Combination Figure 1-Figure 3 The embodiment of the present application provides a flange repair device, including a repair component 1; the repair component 1 includes: a base 11 with a frame 12 on the top; a hydraulic rod 121 is arranged on the inner side of the frame 12; a rust removal mechanism 13 is arranged at the bottom of the hydraulic rod 121; a frame 14 is arranged on the top of the base 11; a motor 15 is arranged on the frame 14; a worm 151 is rotatably arranged on the inner side of the frame 14 and connected to the motor 15; a transmission rod 16 is rotatably arranged on the top of the base 11; a worm wheel 161 is arranged on the outer side of the transmission rod 16; a support plate 17 is arranged on the top of the transmission rod 16; a support rod 171 is symmetrically arranged on the top of the support plate 17; a hydraulic rod 18 is symmetrically arranged on the outer side of the support rod 171; a limit block 181 is arranged at one end of the hydraulic rod 18; and a flange 19 is sleeved on the outer side of the support rod 171.

[0033] First, the flange 19 to be derusted is sleeved on the outside of the support rod 171, and then the hydraulic rod 18 is started by an external power supply to drive the limit block 181 to expand to both sides, so as to support and fix the inner wall of the flange 19. In this way, the flange 19 can be fixed to the outside of the support rod 171. After the flange 19 is fixed in sequence, the hydraulic rod 121 is started by an external power supply to drive the rust removal mechanism 13 to descend, and then the rust removal mechanism 13 is started to derust the flange 19. The rust removal mechanism 13 is a mechanism that drives a rust removal knife to derust the workpiece by a motor. With reference to the "

[0059] " paragraph in the specification of the utility model publication number "CN218133486U", the rust removal mechanism 13 is common knowledge and will not be repeated here. When the rust removal is completed, the hydraulic rod 121 is started again to lift the rust removal mechanism 13, and the motor 15 is started by an external power supply to drive the worm 151 to rotate The worm 151 drives the meshing worm wheel 161 to rotate, and the worm wheel 161 drives the transmission rod 16 to rotate, and drives the support plate 17 to rotate, so that the flange 19 that has been rust-removed can be moved out, and the lower flange 19 is moved to the bottom of the rust-removing mechanism 13, and then the rust-removing mechanism 13 is used again to remove the rust, and then the operator removes the flange 19 that has been rust-removed, so that the flange 19 can be repaired and rust-removed while being replaced, making the disassembly and assembly of the flange 19 more convenient and increasing the working efficiency. The hydraulic rod is a kind of hydraulic oil that enters the oil cylinder through a one-way valve through a manual booster pump. At this time, the hydraulic oil entering the oil cylinder cannot go back because of the one-way valve, forcing the piston rod upward, and then the work continues to make the hydraulic oil continue to enter the hydraulic oil cylinder, so that the piston rod continues to rise, and when it is to be lowered, the hydraulic valve is opened to return the hydraulic oil to the oil tank, and the piston rod can be retracted again. The corresponding principle structure of this section is not drawn in the attached figure.
