Description

Technical Field

[0001] The present invention relates to the technical field of maintenance equipment, and specifically to a boiler maintenance device for power plants. Background Technique

[0002] A power plant boiler room refers to the facilities used in the process of providing steam or hot water for power generation and other needs, and is the core part of a power plant. It usually includes equipment such as boilers, pumps, pipelines, heat exchangers, etc., and is equipped with a power distribution room, a control room, and a maintenance area, etc.

[0003] Inside the boiler, the wind cap is an important component in the boiler combustion system, and the working principle of the boiler wind cap is based on the principle of fluid mechanics. By adjusting the structure and layout of the wind cap, uniform and stable airflows are formed in the combustion chamber. Inside the combustion chamber, fuel and air need to be fully mixed to burn and generate heat energy. A certain flow field is formed at the air inlet of the boiler wind cap, enabling air to enter the combustion chamber evenly, avoiding situations where the air volume is too small in some areas and the fuel does not burn completely. At the same time, inside the boiler, the air flow needs to gradually decrease to ensure complete combustion. The boiler wind cap also gradually decelerates the high-speed flowing air through components such as the air outlet and the deflector plate, thereby achieving the control of the fuel-air ratio.

[0004] When performing maintenance on the inside of the boiler, workers need to use a hammer to remove the wind cap, and then use a grinding machine to re-grind the removed wind cap, and then use a welding torch to weld the re-ground wind cap back into the pipeline. However, there are many wind caps in the boiler, and workers need to constantly change the operating tools. This replacement process is rather cumbersome, requiring the worker to first turn off the working tool and then replace it with a new one, reducing the maintenance efficiency, and the maintenance tools that are always in the powered-on state pose a certain risk; therefore, it does not meet the existing requirements, and for this reason, we propose a boiler maintenance device for power plants.

[0016] As an optional solution of a power plant boiler maintenance device described in the present invention, a limiting device is arranged in the shell, and the limiting device includes a piston slide groove opened in the shell, a piston plate is slidably connected in the piston slide groove, a driving rod is fixedly connected to the bottom of the piston plate, and the other end of the driving rod is fixedly connected to the top of the positioning block.

[0017] The present invention has the following beneficial effects: 1. The boiler maintenance device of the power plant, through the rotation of the rotating device, enables the maintenance personnel to not need to frequently take the maintenance tools from their body during the maintenance process, but only need to control the motor to drive the maintenance tools to be directly replaced in the shell. Compared with the traditional method of carrying multiple maintenance tools, this method can simplify the operation of replacing maintenance tools by the maintenance personnel, and to a certain extent improve the maintenance efficiency. When the maintenance tool is rotated to the upper side, the abutment block fixedly connected to the inner side of the shell abuts against the cross power rod in the installation rod. Since one end of the cross power rod is designed to The inclined surface makes the abutment block abut against the inclined surface of the cross power-on rod and drives the cross power-on rod to slide to the right inside the power-on rod. Under the abutment of the abutment block, the other end of the cross power-on rod abuts against the power-on rod. At this time, the maintenance tool above the shell starts to be energized under the power supply of the power supply device. At this time, the maintenance personnel can operate the maintenance tool to work on the part that needs maintenance. Through this design, it can effectively ensure that the maintenance tool is powered on during the maintenance process and is powered off during the replacement of the maintenance tool, thereby effectively ensuring the safety of the maintenance personnel.

[0018] 2. In the boiler maintenance device of the power plant, when the resistance block slides in the arc groove, when the maintenance worker confirms that the positioning of the power-on positioning device is completed, the power supply slide bar slides to the right under the action of the anti-disconnection spring. In this process, one side of the power supply slide bar resists the bottom of the fixed rod. Since the bottom of the fixed rod is set as an inclined surface, the fixed rod slides upward under the resistance of the power supply slide bar and is inserted into the fixed slot. Since the fixed rod and the fixed slot are designed to be rectangular, the installation rod will not be able to rotate after the fixed rod is inserted into the fixed slot. At this time, the installation rod will be stuck under the action of the fixing device and cannot rotate relative to the shell. When the maintenance is completed, the maintenance worker pulls out the power supply slide bar through the handle. At this time, the fixed rod slides downward under the action of the reset spring, and the fixation between the installation rod and the shell is released. At this time, the installation rod can continue to rotate. Through this design, the stability of the maintenance tool during the maintenance process is effectively improved, and the safety of the maintenance is guaranteed.

[0019] 3. The boiler maintenance device of the power plant limits the current connection between the power supply slide rod and the connection block when replacing the maintenance tool through the design of the limiting device. When replacing the tool, it is necessary to pull out the power supply slide rod by the handle first. At the same time, the rotating motor starts to work. At this time, the positioning block slides upward under the resistance of the side wall of the mounting rod, and then drives the driving rod fixedly connected to the top of the positioning block to drive the piston plate to slide upward. Therefore, the limiting slide plate pulled to the left side of the limiting slide groove cannot slide to the right under the restriction of the piston plate. Through this design, it can effectively ensure that the power supply slide rod cannot be connected to the connection block, thereby further reducing the risk of leakage and improving safety at work.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1. The purpose of this embodiment is to facilitate the solution of the problem that the process of continuously replacing operation tools is rather cumbersome, reducing the maintenance efficiency, and there may be safety hazards if the maintenance tools are in an electrified state during the replacement process. Please refer to Figures 1 to 8 , a boiler maintenance device for a power plant, including a housing 1. A rotating device 2 is installed inside the housing 1. The rotating device 2 includes a rotating groove 21 opened inside the housing 1. A rotating rod 22 is rotatably connected inside the rotating groove 21. A mounting rod 24 is fixedly connected to the side wall of the rotating rod 22. A welding device 25 is installed at one end of the mounting rod 24, and a cutting device 26 is installed at the other end of the mounting rod 24.

[0031] A rotating motor 23 is installed inside the rotating groove 21. The output end of the rotating motor 23 is fixedly connected to the mounting rod 24.

[0032] Under the control of the rotating electric machine 23, the required maintenance tools can be rotated above the housing 1. At this time, the maintenance personnel can directly supply power to the maintenance tools located above the housing 1 through the storage battery 55. Through this design, the maintenance personnel can quickly replace the maintenance tools. Compared with the traditional method of carrying multiple maintenance tools, this method can simplify the operation of the maintenance personnel to replace the maintenance tools and improve the maintenance efficiency to a certain extent.

[0033] The installation rod 24 is provided with a contact power-on device 4. The contact power-on device 4 includes an installation groove 41 opened in the installation rod 24. An energizing rod 42 is installed in the installation groove 41. The energizing rod 42 is used to supply power to the cutting device 26 and the welding device 25. One side of the energizing rod 42 is electrically connected to a cross energizing rod 43. The other end of the cross energizing rod 43 is provided with a power supply device 5.

[0034] The cross energizing rod 43 is slidably connected in a cross sliding groove 44. The cross sliding groove 44 is opened in the installation rod 24. The cross sliding groove 44 communicates with the installation groove 41. One side of the cross energizing rod 43 is fixedly connected to a cross spring 45. The other end of the cross spring 45 is fixedly connected in the cross sliding groove 44.

[0035] The cross energizing rod 43 is abutted by a abutting block 47. The abutting block 47 is fixedly connected to one side of the housing 1. An arc groove 46 is opened on one side of the installation rod 24 close to the abutting block 47. The abutting block 47 is slidably connected in the arc groove 46.

[0036] The design of the contact power-on device 4 enables the circuit to be quickly disconnected when replacing the maintenance tools before starting the replacement. This design effectively ensures the safety when replacing the maintenance tools.

[0037] When the maintenance tool is rotated above, the abutting block 47 fixedly connected to the inner side of the housing 1 abuts the cross energizing rod 43 in the installation rod 24. Since one end of the cross energizing rod 43 is designed as an inclined surface, the abutting block 47 will abut the inclined surface of the cross energizing rod 43 and drive the cross energizing rod 43 to slide to the right in the cross sliding groove 44. Under the abutment of the abutting block 47, the other end of the cross energizing rod 43 abuts against the energizing rod 42. At this time, under the power supply of the power supply device 5, the maintenance tools above the housing 1 start to be powered on. At this time, the maintenance personnel can operate the maintenance tools to work on the parts to be maintained. Through this design, it can be effectively ensured that the power is supplied during the maintenance process and the maintenance tools are powered off during the process of replacing the maintenance tools, effectively ensuring the safety of the maintenance personnel.

[0038] Inside the housing 1, there is an energized positioning device 3. The energized positioning device 3 includes a positioning card slot 31 opened inside the housing 1. A positioning card block 32 is inserted into the positioning card slot 31. The positioning card block 32 is slidably connected in a positioning chute 34. The positioning chute 34 is opened inside the housing 1. One side of the positioning card block 32 is fixedly connected to a positioning spring 33. The other end of the positioning spring 33 is fixedly connected inside the positioning chute 34.

[0039] The design of the energized positioning device 3 is used to ensure that after the installation rod 24 rotates, it can be confirmed that the maintenance tool is directly above, so as to ensure that the energized circuit can be smoothly connected. When the installation rod 24 rotates to the correct position, the positioning card block 32 that is abutted against the side wall of the installation rod 24 in the positioning chute 34 is inserted into the positioning card slot 31 under the action of the positioning spring 33. A component that can make a sound, such as a metal like an iron sheet, can be arranged in the positioning card slot 31. After the positioning card block 32 is inserted into the positioning card slot 31, the collision between the two metal blocks makes a sound. Through this suggestive design, it can tell the maintenance worker that the maintenance tool has rotated to the correct position. At this time, the maintenance worker can operate the power supply device 5 to supply power to the maintenance tool, effectively ensuring the correct connection of the circuit.

[0040] The power supply device 5 includes a connection block 51 installed at one end of the abutting block 47. One end of the connection block 51 is electrically connected to the cross energizing rod 43. The other end of the connection block 51 is electrically connected to the power supply slide rod 52.

[0041] The power supply slide rod 52 is slidably connected in a power supply chute 53. The power supply chute 53 is opened inside the housing 1. The bottom of the power supply slide rod 52 is fixedly connected to a limit slide plate 57. One side of the limit slide plate 57 is equipped with a power supply cable 54. The other end of the power supply cable 54 is connected to a storage battery 55. The storage battery 55 is installed inside the housing 1.

[0042] The limit slide plate 57 is slidably connected in a limit chute 56. The limit chute 56 is opened inside the housing 1. One side of the limit chute 56 is fixedly connected to an anti-disconnection spring 58. The other end of the anti-disconnection spring 58 is fixedly connected inside the limit chute 56. The end of the power supply slide rod 52 far from the connection block 51 is fixedly connected to an insulating rod 510. The other end of the insulating rod 510 extends out of the housing 1. A handle 59 is installed at the end of the insulating rod 510 that extends out of the housing 1.

[0043] The power supply device 5 is used to supply power to the maintenance tool. After the maintenance worker confirms that the maintenance tool has been rotated to the correct position through the design of the power-on positioning device 3, when the limiting device 7 is released, the power supply slide bar 52 slides to the right under the action of the anti-disconnection spring 58. At this time, one end of the power supply slide bar 52 conflicts with the connecting block 51, and the other end of the connecting block 51 conflicts with the cross power-on rod 43. At this time, the battery 55 can transmit current to the maintenance tool through the power supply cable 54, the limiting slide plate 57, the power supply slide bar 52, the connecting block 51, the cross power-on rod 43 and the power-on rod 42 in this order, thereby ensuring the normal operation of the maintenance process.

[0044] Embodiment 2: This embodiment is intended to facilitate solving the problem of unstable connection between the mounting rod 24 and the abutment block 47. This embodiment is an explanation based on the embodiment 1. For details, please refer to Figures 1 to 8 A fixing device 6 is provided between the resistance block 47 and the mounting rod 24, and the fixing device 6 includes a fixing slot 61 provided in the mounting rod 24, a fixing rod 63 is inserted in the fixing slot 61, the fixing rod 63 is slidably connected in the fixing slide slot 62, the fixing slide slot 62 is provided in the resistance block 47, a side wall of the fixing rod 63 is fixedly connected with a limiting plate 65, the limiting plate 65 is slidingly connected in the limiting groove 64, the limiting groove 64 is provided in the resistance block 47, a return spring 66 is fixedly connected to the bottom of the limiting plate 65, and the other end of the return spring 66 is installed in the limiting groove 64.

[0045] During the sliding of the abutment block 47 in the arc groove 46, when the maintenance worker confirms that the positioning of the power-on positioning device 3 is completed, the power supply slide bar 52 slides to the right under the action of the anti-disconnection spring 58. During this process, one side of the power supply slide bar 52 abuts against the bottom of the fixed rod 63. Since the bottom of the fixed rod 63 is set as an inclined surface, the fixed rod 63 slides upward under the abutment of the power supply slide bar 52 and is inserted into the fixed card slot 61. Since the fixed rod 63 and the fixed card slot 61 are designed to be rectangular, the fixed rod 63 is inserted into the fixed card slot 61. After the groove 61 is formed, the mounting rod 24 will be unable to rotate. At this time, the mounting rod 24 will be stuck under the action of the fixing device 6 and cannot rotate relative to the shell 1. When the maintenance is completed, the maintenance worker pulls out the power supply slide bar 52 through the handle 59. At this time, the fixing rod 63 slides downward under the action of the reset spring 66, and the fixation between the mounting rod 24 and the shell 1 is released. At this time, the mounting rod 24 can continue to rotate. Through this design, the stability of the maintenance tool during the maintenance process is effectively improved, and the safety of the maintenance is ensured.

[0046] Embodiment 3: This embodiment is intended to help solve the problem that the pluggable power supply slide bar 52 may fall off. This embodiment is an explanation based on Embodiment 2. For details, please refer to Figures 1 to 8, a limiting device 7 is arranged inside the housing 1. The limiting device 7 includes a piston chute 71 formed inside the housing 1. A piston plate 72 is slidably connected inside the piston chute 71. The bottom of the piston plate 72 is fixedly connected to a driving rod 73. The other end of the driving rod 73 is fixedly connected to the top of the positioning block 32.

[0047] The design of the limiting device 7 limits the current connection between the power supply slide rod 52 and the connection block 51 when replacing and overhauling tools. When replacing the tool, it is necessary to first pull out the power supply slide rod 52 through the handle 59. At the same time, the rotating motor 23 starts to work. At this time, the positioning block 32 slides upward under the resistance of the side wall of the rotating rod 22, and then drives the driving rod 73 fixedly connected to the top of the positioning block 32 to drive the piston plate 72 to slide upward. Therefore, the limiting slide plate 57 pulled to the left side of the limiting chute 56 cannot slide to the right under the restriction of the piston plate 72. Through this design, it can effectively ensure that the power supply slide rod 52 cannot be connected to the connection block 51, thereby further reducing the risk of electric leakage and improving the safety during work.

[0048] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0049] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
