Description

Technical Field

[0001] The invention belongs to the technical field of thermal power plant maintenance, and in particular relates to a thermal power plant equipment maintenance device. Background Art

[0002] A thermal power plant is a factory that burns combustibles to generate electricity. It includes equipment such as boilers, steam turbines and generators. In addition, it also includes many auxiliary equipment. In order to maintain the normal operation of the thermal power plant, it is necessary to conduct regular maintenance of the equipment in the thermal power plant. During the maintenance process, some equipment needs to be hoisted using lifting equipment. The equipment needs to be hoisted to the maintenance platform to facilitate more detailed maintenance of the thermal power plant equipment.

[0003] Chinese patent CN219239001U discloses a kind of steam turbine maintenance hoisting equipment for thermal power plants, including a support frame, a horizontal plate, a hook and a clamping device, wherein the support frame is slidably provided with a first slider and a second slider, the first slider is provided with a horizontal plate, and the middle position of the horizontal plate is provided with a hook; the second slider is provided below the first slider, and the second slider is provided with a clamping device through a telescopic rod; the clamping device includes an upper pressure plate, a lower pressure plate and a screw frame, the bottom end of the screw frame is welded with a lower pressure plate, an upper pressure plate screw is provided in the screw frame, a driving block is provided on the upper pressure plate screw, and an upper pressure plate is provided on the driving block, and a clamping mechanism is provided on the upper pressure plate. The steam turbine maintenance hoisting equipment for thermal power plants effectively solves the problem that the steam turbine clamping device of the existing steam turbine maintenance hoisting equipment can only correspond to one or a specific type of steam turbine.

[0004] The above-mentioned prior art proposed the thermal power plant steam turbine maintenance hoisting equipment, although it solves the problem that the steam turbine clamping device can only correspond to one or a specific type of steam turbine, but it does not solve the problem of the shaking of the thermal power plant equipment during the hoisting process. At present, most of the hoisting equipment is equipped with an anti-sway system. However, when the hoisting operation is carried out during the maintenance of the thermal power plant equipment, the anti-sway system can only reduce the swing amplitude of the thermal power plant equipment, and it is difficult to prevent the thermal power plant equipment from shaking during the hoisting process, which makes the wire rope on the hoisting equipment more worn and reduces the service life of the wire rope; although the thermal power plant equipment is not stable, the hoisting equipment is not stable, and the maintenance work is not smooth. Before the power plant equipment is hoisted, the components and wire ropes on the hoisting equipment will be inspected to determine whether there are any safety hazards in the hoisting equipment and whether normal hoisting operations can be carried out. If during the inspection, due to improper operation of the operator or other reasons, no defects in the wire rope are found, then during the hoisting process, the wire rope may break, causing the thermal power plant equipment to fall from the hoisting equipment, causing not only equipment damage but also casualties; and at the moment the wire rope breaks, the thermal power plant equipment will deviate from the hoisting equipment, causing scratches and damage to the thermal power plant equipment.

[0005] Therefore, we propose a thermal power plant equipment maintenance device to solve the above-mentioned problems. Summary of the invention

[0023] The present invention is further described below in conjunction with specific embodiments.

[0024] In order to solve the problem that the equipment of the thermal power plant shakes greatly during the process of hoisting the equipment of the thermal power plant, which aggravates the wear of the wire rope 20, such as Figure 1 - Fig.13 As shown: A thermal power plant equipment maintenance device, comprising a gantry 1, the gantry 1 is used to support and fix various components, the lower end of the gantry 1 is provided with a plurality of driving mechanisms 2, the setting of the driving mechanism 2 is used to drive the entire maintenance device to move, hoist the thermal power plant equipment to the maintenance platform, and carry out a comprehensive maintenance, the gantry 1 is provided with a plurality of moving components 3, the moving components 3 can adjust the hoisting spacing, so as to facilitate the hoisting of thermal power plant equipment of different sizes, the lower part of the moving component 3 is provided with a first winding component 4, ... A second winding component 10 is provided on the top of the component 3, and the first winding component 4 and the second winding component 10 are respectively wound with wire ropes 20. The free end of the wire rope 20 on the first winding component 4 is fixedly connected to a hook. When lifting, the hook is hung on the thermal power plant equipment, and then the wire rope 20 is rolled up by the first winding component 4, thereby realizing the lifting of the thermal power plant equipment. The second winding component 10 serves as a backup. During the lifting process, when the wire rope 20 on the first winding component 4 breaks, the second winding component 10 will be activated.

[0025] Adjustment components 5 are fixedly arranged on the outer walls on both sides of the travel component 3, which are used to adjust the lifting width to ensure that the lifting width is greater than the width of the thermal power plant equipment, thereby ensuring the smooth progress of the lifting work. First electric telescopic columns 7 are rotatably arranged on the outer walls of the two adjustment components 5, and the output ends of the two first electric telescopic columns 7 are fixedly connected with anti-scratch components 8 respectively. Steering components 6 are fixedly arranged on the top surfaces of the two adjustment components 5. In the initial state, the first electric telescopic column 7 is in a parallel state with the gantry 1. When the staff hangs the hook of the free end of the wire rope 20 on the first winding component 4 on the thermal power plant equipment, the steering component 6 is started. The steering component 6 drives the first electric telescopic column 7 to rotate 90°, so that the output end of the first electric telescopic column 7 is close to the thermal power plant equipment, and then the first electric telescopic column 7 is started. The extension of the first electric telescopic column 7 will drive the anti-scratch component 8 to move downward. When the anti-scratch component 8 moves to a suitable position, the first electric telescopic column 7 stops extending. At this time, the anti-scratch components 8 on both sides are started to clamp the thermal power plant equipment.

[0026] A telescopic component 9 is provided on the outer wall of one of the first electric telescopic columns 7, a steel wire rope 20 on the second winding component 10 is slidably arranged inside the telescopic component 9, a free end of the steel wire rope 20 on the second winding component 10 is fixedly connected with a hook 30, and a pulling component 40 is fixedly provided on the bottom surface of the anti-scratch component 8 away from the hook 30. Since the telescopic component 9 is elastic, when the first electric telescopic column 7 is extended, the second winding component 10 synchronously relaxes the steel wire rope 20, so that the hook 30 cancels the pressure applied to the telescopic component 9, and the telescopic component 9 will extend under the action of elasticity. When the first electric telescopic column 7 stops extending, The second winding component 10 immediately stops running and positions. At this time, the pulling component 40 is started to extend and engage with the hook 30. Then, the second winding component 10 continues to relax the wire rope 20. The pulling component 40 synchronously pulls the hook 30 to pass under the thermal power plant equipment hoisted by the first winding component 4 until the pulling component 40 returns to its original position. The pulling component 40 stops running. At this time, the wire rope 20 is wound by the second winding component 10, and the wire rope 20 is attached to the bottom surface of the thermal power plant equipment to play a preventive role. When the wire rope 20 on the first winding component 4 breaks, the thermal power plant equipment will not fall directly to the ground.

[0027] The travel assembly 3 includes a travel frame 31, on the inner wall of which a plurality of rollers 32 are rotatably mounted, the plurality of rollers 32 being connected to each other through belts, the rollers 32 being rotatably mounted on the gantry 1, and a plurality of first motors 33 being fixedly mounted on the outer wall of the travel frame 31, the output shafts of the first motors 33 being rotatably mounted on the outer wall of the travel frame 31, the output shafts of the first motors 33 being fixedly connected to the rollers 32, and when hoisting and repairing the thermal power plant equipment, the first motors 33 are first started to drive the rollers 32 to rotate, thereby driving the travel assembly 3 and other components mounted on the travel assembly 3 to move to a suitable hoisting spacing, so as to ensure that the thermal power plant equipment can be stably hoisted.

[0028] The first winding assembly 4 includes a first winding roller 42 rotatably mounted at the lower part of the traveling frame 31, a steel wire rope 20 is wound on the first winding roller 42, a second motor 41 is fixedly mounted on the side wall of the traveling frame 31, an output shaft of the second motor 41 penetrates and is rotatably arranged on the side wall of the traveling frame 31, and the output shaft of the second motor 41 is fixedly connected to the first winding roller 42. When it is necessary to hoist and overhaul the thermal power plant equipment, the staff first hangs the hook of the free end of the steel wire rope 20 on the first winding roller 42 on the thermal power plant equipment, and then drives the first winding roller 42 to rotate by the second motor 41 to wind up the steel wire rope 20, thereby realizing the hoisting and overhaul of the thermal power plant equipment.

[0029] The positioning assembly 5 includes a plurality of first electric push rods 51 fixedly mounted on the side wall of the traveling frame 31, and a mounting plate 52 is fixedly mounted on the output ends of the plurality of first electric push rods 51. When the first winding assembly 4 has hoisted the thermal power plant equipment, the first electric push rods 51 are started to extend, driving the mounting plate 52 and other components mounted on the mounting plate 52 to move, so that the hoisting width is greater than the width of the thermal power plant equipment, thereby ensuring the smooth progress of the hoisting work.

[0030] The steering assembly 6 includes a third motor 61 fixedly mounted on the top surface of the mounting plate 52, a driving gear 62 is fixedly connected to the output end of the third motor 61, a plurality of tooth blocks 63 are fixedly mounted on the outer wall of the top end of the first electric telescopic column 7, and the driving gear 62 is meshedly connected with the tooth block 63. The third motor 61, the driving gear 62 and the tooth block 63 are matched to drive the first electric telescopic column 7 and other components mounted on the first electric telescopic column 7 to rotate.

[0031] Specifically, in the initial state, the first electric telescopic column 7 is parallel to the gantry 1. When the staff hangs the hook of the free end of the wire rope 20 on the first winding roller 42 on the thermal power plant equipment, the third motor 61 is started. The third motor 61 cooperates with the driving gear 62 and the gear block 63 to drive the first electric telescopic column 7 to rotate 90°, so that the output end of the first electric telescopic column 7 is close to the thermal power plant equipment, and then the first electric telescopic column 7 is started. The extension of the first electric telescopic column 7 will drive the anti-scratch component 8 to move downward. When the anti-scratch component 8 moves to a suitable position, the first electric telescopic column 7 stops extending. At this time , respectively start the anti-scratch components 8 on both sides to clamp the thermal power plant equipment. Through such a setting, the first electric telescopic column 7 and the anti-scratch component 8 play a role in limiting the thermal power plant equipment. In the process of lifting the thermal power plant equipment by the maintenance device, the amplitude of the shaking of the thermal power plant equipment can be reduced. Then, in cooperation with the anti-sway system on the maintenance equipment, the shaking of the thermal power plant equipment can be reduced to a great extent. Compared with simply relying on the anti-sway system to suppress the shaking of the thermal power plant equipment, the setting of the present invention can better suppress the shaking of the thermal power plant equipment, reduce the wear of the wire rope 20, and extend the service life of the equipment.

[0032] In order to solve the problem that when the steel wire rope 20 on the first winding assembly 4 breaks, the thermal power plant equipment directly falls to the ground, causing damage to the thermal power plant equipment and injuries to personnel, as shown in the following example: Figure 1 - Figure 8 and Figure 10-13 As shown: The telescopic assembly 9 includes a telescopic tube 91 fixedly mounted on the outer side wall of the first electric telescopic column 7, a pulley block 1 92 is fixedly mounted on the side wall of the inner cavity at the top of the telescopic tube 91, a pulley block 2 93 is fixedly mounted on the outer side wall at the top of the first electric telescopic column 7, and the wire rope 20 on the second winding assembly 10 is penetrated through the pulley block 1 92, the pulley block 2 93 and the telescopic tube 91. The setting of the pulley block 1 92 and the pulley block 2 93 is used to limit the wire rope 20 and reduce the wear of the wire rope 20, which can extend the service life of the wire rope 20.

[0033] The second winding assembly 10 includes a second winding roller 102 rotatably mounted on the top surface of the traveling frame 31 , on which the steel wire rope 20 is wound, and a fourth motor 101 is fixedly mounted on the top surface of the traveling frame 31 , wherein the output shaft of the fourth motor 101 is fixedly connected to the second winding roller 102 .

[0034] The pulling assembly 40 includes a fixing plate 401 fixedly mounted on the bottom surface of the anti-scratch assembly 8 away from the hook 30 , a second electric push rod 402 is fixedly mounted on the inner side wall of the fixing plate 401 , and a snap-fit ​​assembly 403 is fixedly mounted on the output end of the second electric push rod 402 .

[0035] The snap-fit ​​assembly 403 includes a limit plate 4031 fixedly mounted on the output end of the second electric push rod 402, a slide groove 4032 is opened on the side wall of the limit plate 4031, a buckle ring 4033 is slidably mounted in the inner cavity of the slide groove 4032, the bottom surface of the buckle ring 4033 and the bottom wall of the inner cavity of the slide groove 4032 are elastically connected by a spring 4034, a pair of permanent magnets 4035 are fixedly mounted on the top surface of the buckle ring 4033, and a pair of electromagnets 4036 are fixedly mounted on the top wall of the inner cavity of the slide groove 4032, and the electromagnets 4036 and the permanent magnets 4035 are aligned with each other.

[0036] Specifically, since the telescopic tube 91 is elastic, when the first electric telescopic column 7 is extended, at the same time, the fourth motor 101 drives the second winding roller 102 to rotate, relaxes the wire rope 20, and makes the hook 30 cancel the pressure applied to the telescopic component 9. The telescopic component 9 will extend under the action of elasticity. When the first electric telescopic column 7 stops extending, the fourth motor 101 drives the second winding roller 102 to stop rotating and position. At this time, the second electric push rod 402 is started to drive the buckling component 403. When the buckling component 403 is close to the hook 30, the electromagnet 4036 is energized again, so that an attraction is generated between the electromagnet 4036 and the permanent magnet 4035. Under the action of the attraction, the buckle 4033 slides upward in the inner cavity of the slide groove 4032. At this time, the second electric push rod 402 continues to extend. When the buckle 4033 is directly above the bending part of the hook 30 , the electromagnet 4036 is powered off, and under the elastic force of the spring 1 4034, the buckle 4033 slides downward in the inner cavity of the slide groove 4032 and just engages with the bent part of the hook 30. After the engagement operation is completed, the fourth motor 101 drives the second winding roller 102 to continue to relax the wire rope 20, and the second electric push rod 402 begins to shorten and reset. In the process of shortening and resetting the second electric push rod 402, the buckle 4033 will pull the hook 30 through the bottom of the thermal power plant equipment hoisted by the first winding assembly 4 until the second electric push rod 402 returns to its original position, and the second electric push rod 402 stops running. At this time, the fourth motor 101 drives the second winding roller 102 to rotate in the opposite direction to rewind the wire rope 20. In the process of rewinding the wire rope 20, the relatively loose wire rope 20 will be attached to the bottom surface of the thermal power plant equipment, which plays a preventive role.

[0037] When the steel wire rope 20 on the first winding component 4 breaks, the thermal power plant equipment will not fall directly to the ground, which reduces the probability of the thermal power plant equipment being damaged by falling, and also reduces the probability of personal injury. In addition, when the steel wire rope 20 on the second winding component 10 is tightened, it can pull the two relative first electric telescopic columns 7 and the anti-scratch component 8, thereby enhancing the stability of the first electric telescopic columns 7 and the anti-scratch component 8, and further enhancing the anti-sway effect of the thermal power plant equipment. In addition, it can also relieve the working pressure of the first electric telescopic column 7 and the anti-scratch component 8, and prevent the thermal power plant equipment from being overweight and colliding and deforming the first electric telescopic column 7 and the anti-scratch component 8 during the movement.

[0038] In order to solve the problem that when the wire rope 20 on the first winding assembly 4 breaks, the clamping plate 85 scratches the surface of the thermal power plant equipment, such as Figure 3 - Figure 4 and Figure 8 As shown: The anti-scratch component 8 includes a mounting shell 81 fixedly mounted on the output end of the first electric telescopic column 7, and long through grooves 82 are respectively provided on the side walls on both sides of the inner cavity of the mounting shell 81, and a lifting seat 83 is slidably mounted inside the long through groove 82. The bottom surface of the lifting seat 83 and the bottom surface of the inner cavity of the mounting shell 81 are elastically connected by a spring 86, and a plurality of third electric push rods 84 are fixedly mounted on the outer wall of the lifting seat 83, and a splint 85 is fixedly connected to the output end of the third electric push rod 84, and racks 87 are respectively fixedly mounted on the side walls on both sides of the lifting seat 83, and load-bearing rods 88 are rotatably mounted on the outer walls on both sides of the lower part of the mounting shell 81, and the racks 87 and the load-bearing rods 88 are meshingly connected.

[0039] Specifically, when the first winding component 4 has completed the hoisting of the thermal power plant equipment, it is started, and after the first electric telescopic column 7 and the anti-scratch component 8 are moved into place through the steering component 6, the third electric push rod 84 is started to extend, and the clamping plate 85 is pressed against the thermal power plant equipment hoisted by the first winding component 4, and cooperates with the anti-sway system to reduce the shaking of the thermal power plant equipment during the hoisting process; during the hoisting process, when the wire rope 20 on the first winding component 4 breaks, even with the cooperation of the second winding component 10, the thermal power plant equipment will not fall to the ground. However, when the wire rope 20 on the first winding component 4 breaks, it takes time to start the second winding component 10. During this period of time, the thermal power plant equipment will fall down a distance, and when the wire rope 20 on the first winding component 4 breaks, the center of gravity of the thermal power plant equipment will shift, and it will slide on the clamping plate 85, causing the surface of the thermal power plant equipment to be scratched. In order to alleviate this problem, the present invention is provided with an anti-scratch component 8. In the initial state, the spring When the second winding assembly 86 is in a stress-free state, when the wire rope 20 on the first winding assembly 4 breaks and the center of gravity of the thermal power plant equipment is unstable, one end of the thermal power plant equipment will fall downward for a distance. Since the splint 85 is in conflict with the surface of the thermal power plant equipment, when one end of the thermal power plant equipment falls downward, it will drive the splint 85, the third electric push rod 84 and the lifting seat 83 to move downward for a distance. When the lifting seat 83 moves downward, the rack 87 moves downward synchronously with the lifting seat 83. During the movement, the rack 87 will drive the load-bearing rod 88 to flip in the direction close to the thermal power plant equipment until the load-bearing rod 88 is in conflict with the thermal power plant equipment. At this time, the load-bearing rod 88 is hindered and cannot continue to flip, thereby making the lifting seat 83 unable to descend, and thereby making the thermal power plant equipment unable to continue to fall. At this time, the second winding assembly 10 has been started, and the thermal power plant equipment can be hoisted to the original height. Under the elastic force of the second spring 86, the various components in the anti-scratch assembly 8 begin to reset for the next use.

[0040] Through the setting of the above-mentioned anti-scratch component 8, when the wire rope 20 on the first winding component 4 breaks, it can assist the second winding component 10, and can prevent the thermal power plant equipment from falling to the ground during the gap when the second winding component 10 is started, thereby causing equipment damage and casualties. In addition, since the splint 85, the third electric push rod 84 and the lifting seat 83 can move downward with the thermal power plant equipment, such a setting can greatly reduce the relative displacement between the thermal power plant equipment and the splint 85 compared to the traditional one that cannot move, thereby achieving an anti-scratch effect.

[0041] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
