Description

TECHNICAL FIELD

[0002] In today's industrial field, as the core equipment of energy supply system, boilers are widely used in power, chemical industry, metallurgy and many other industries. With the continuous improvement of industrial production capacity, the equipment specifications of boilers are gradually developing towards large-scale and high-parameter, and the maintenance and repair requirements of the internal pipes, hearths, heating surfaces and other components of the boilers are increasingly urgent. The corresponding boiler equipment maintenance and repair operations are also attracting increasing attention in the industry.

[0003] At present, the maintenance operation of the boiler equipment needs to be carried out in a specific height and space, so the operating personnel need to approach the maintenance site by means of a maintenance platform. Correspondingly, the traditional large-scale maintenance platform currently applied in the industry has a main frame made of steel, which is large in overall size and heavy in weight. The platform equipment is only fixedly arranged with fixed support feet on the ground, and cannot realize the overall flexible movement of the maintenance platform. It also cannot be deployed in the narrow space inside the boiler (such as the hearth and flue) to implement maintenance and repair and other supporting operations at the corresponding workstations, which restricts the working condition adaptability and use convenience of the maintenance platform, and cannot meet the boiler maintenance and repair requirements in multiple working conditions.

[0004] In addition, the existing maintenance platform needs to rely on external equipment (such as a crane and a forklift) to realize overall handling and position adjustment. This operation process needs to be completed by multiple people in cooperation to carry out frame splicing and component installation and other processes, and needs to rely on external hoisting equipment for assistance during the process. The operation process is complicated and the workload is extremely large, resulting in that the pre-assembly and post-disassembly of the boiler maintenance platform are extremely time-consuming and laborious, and the labor intensity of the workers is large. Correspondingly, due to the large weight and complex structure of the supporting components of the existing maintenance platform, it is difficult to store and transport, and the labor and time cost inputs during storage and use are large, which cannot meet the emergency maintenance requirements of the boiler equipment and causes many inconveniences to the long-term operation of the boiler equipment.

[0005] Therefore, how to optimize the component structure of the boiler maintenance platform, make the operation and use more convenient and efficient, meet the boiler maintenance and repair requirements in different working conditions, and reduce the labor intensity of the workers, so that the boiler maintenance and repair operation is more simple and easy, is an important technical problem to be solved by the person skilled in the art at present.

Then the worker can implement the corresponding maintenance and repair work on the target work station, and after the work is completed, the worker can be transported to the corresponding position of the next work surface by moving the support frame and the translation frame to the initial position or the next position. If the maintenance and repair work needs to be implemented on another boiler equipment or a work station that cannot be matched by the action mechanism of the boiler maintenance platform, the boiler maintenance platform can be moved to the next boiler equipment or target work station by the walking mechanism, and then the worker on the support frame can be transported to the target work surface by the coordinated action of the lifting drive assembly and the translation drive assembly to implement the corresponding maintenance and repair work.

When the lifting drive assembly operates to adjust the height of the translation frame and support frame, if the translation frame and support frame need to be moved upwards, the output shaft of the take-up and untake-up motor is controlled to rotate forward, causing the take-up and untake-up rollers to rotate forward as well. This shortens the sling connecting the lifting rings and the take-up and untake-up rollers, thereby smoothly lifting the entire translation frame upwards via the lifting rings located at both ends of the translation frame. This also moves the support frame and the personnel on the support frame upwards simultaneously. If the translation frame and support frame need to be moved downwards, the output shaft of the take-up and untake-up motor is controlled to rotate in reverse, causing the take-up and untake-up rollers to rotate in reverse as well. This lengthens the sling connecting the lifting rings and the take-up and untake-up rollers, thereby smoothly lowering the entire translation frame downwards via the lifting rings located at both ends of the translation frame. This also moves the support frame and the personnel on the support frame downwards simultaneously. This allows for the adjustment of the personnel's height, enabling the personnel to be smoothly transferred to the target position. The mechanism, which combines the winding and unwinding rollers with the slings, operates smoothly under the drive of the winding and unwinding motor. This significantly optimizes the stability and reliability of the lifting and moving of the translation frame and support frame, further improving the safety of the workers' position adjustment.

[0041] The core of the present application is to provide a boiler maintenance platform, which is convenient to use and has high operation efficiency, can meet the boiler maintenance and maintenance requirements under different working conditions, and accordingly reduces the labor intensity of workers, so that the boiler maintenance and maintenance operation is more simple and easy.

[0042] In order to make the personnel in the technical field better understand the present application scheme, the present application is further described in detail below in combination with the drawings and specific embodiments.

[0043] In the specific embodiments, in combination with reference to Figure 1 The boiler maintenance platform provided by the present application comprises a horizontal rack 10, lifting frames 11 symmetrically arranged at both ends of the rack 10 and extending in the vertical direction, a translation frame 12 arranged above the rack 10 in parallel and oppositely matched with the two lifting frames 11 at both ends, and a supporting frame 13 movably arranged on the translation frame 12. The boiler maintenance platform further comprises lifting drive assemblies 21 capable of driving the translation frame 12 to reciprocatingly lift along the lifting frames 11, and translation drive assemblies 22 capable of driving the supporting frame 13 to reciprocatingly move along the translation frame 12. The supporting frame 13 is provided with safety belts 131 capable of fixing the workers on the supporting frame 13. The bottom of the rack 10 is provided with a walking mechanism.

[0044] During the operation of the equipment, the workers who need to implement maintenance and repair on the target workstations of the boilers can sit on the supporting frame 13 and be reliably fixed on the supporting frame 13 by the opposite binding of the safety belts 131. Then the translation frame 12 can be driven by the lifting drive assemblies 21 to move vertically upward or downward along the extension structure of the lifting frames 11 to the target height, during which the supporting frame 13 moves upward or downward along with the translation frame 12 to match the target work surface of the boilers that need to be implemented maintenance and repair. Then the supporting frame 13 can be driven by the translation drive assemblies 22 to move horizontally along the extension structure of the translation frame 12 to the target position, so as to transport the workers on the supporting frame 13 to the target work surface of the boilers that need to be implemented maintenance and repair. Then the workers can implement corresponding maintenance and repair work on the target workstations. After the corresponding work is completed, the workers can be transported to the corresponding positions of the next work surface by controlling the lifting drive assemblies 21 and the translation drive assemblies 22 to move the translation frame 12 and the supporting frame 13 to the initial workstations or the next work surface, respectively.

[0045] If the maintenance and repair work needs to be implemented on another boiler equipment or a workstation that cannot be matched by the action mechanism of the boiler maintenance platform, the boiler maintenance platform as a whole can be moved to the next boiler equipment or the target workstation by the walking mechanism. Then the workers on the supporting frame 13 can be transported to the target work surface by the coordinated action of the lifting drive assemblies 21 and the translation drive assemblies 22, so as to implement corresponding maintenance and repair work.

[0046] If the current work is completed and the action assemblies of the boiler maintenance platform are reset, the safety belts 131 can be opened to release the binding of the workers on the supporting frame 13, so that the workers can leave the boiler maintenance platform.

[0047] It is not difficult to see that the operation of the boiler maintenance platform is convenient and efficient. The workers can be safely and accurately transported to the target work station without relying on external equipment such as cranes or forklifts, so as to implement the corresponding boiler maintenance work, so as to meet the boiler maintenance needs under different working conditions. During the transfer process, the workers only need to sit stably on the support frame 13, thereby effectively reducing the labor intensity of the workers, and making the corresponding boiler maintenance work more simple and easy.

[0048] It is not difficult to understand that during actual operation of the equipment, the vertical position of the worker on the support frame 13 can be adjusted in place through the action of the lifting driving assembly 21, and then the horizontal position of the worker on the support frame 13 is adjusted in place through the action of the translation driving assembly 22. Alternatively, the horizontal position of the worker on the support frame 13 can be adjusted in place through the action of the translation driving assembly 22, and then the vertical position of the worker on the support frame 13 is adjusted in place through the action of the lifting driving assembly 21. In actual application, the operation sequence of each action mechanism can be flexibly selected according to the specific working conditions and action space, but considering the position adjustment accuracy and actual space of the equipment in most cases, it is still appropriate to first adjust the vertical position of the worker to the target work station through the action of the lifting driving assembly 21, and then adjust the horizontal position of the worker to the target work station through the action of the translation driving assembly 22.

[0049] Please refer to Figure 3 and Figure 6 for reference. The lifting driving assembly 21 includes a winding and unwinding roller 211 fixed one-to-one on the top of the lifting frame 11, and a winding and unwinding motor 212 capable of driving the winding and unwinding roller 211 to rotate around the horizontal axis. The two ends of the translation frame 12 are respectively provided with a lifting ring 121 corresponding to the winding and unwinding roller 211, and the lifting driving assembly 21 further includes a lifting cable (not shown in the figure) corresponding to the winding and unwinding roller 211. The one end of the lifting cable is fixed to the winding and unwinding roller 211, and the other end of the lifting cable is connected to the lifting ring 121.

[0050] When the lifting driving assembly 21 operates to implement the lifting adjustment of the translation frame 12 and the supporting frame 13, if the translation frame 12 and the supporting frame 13 need to be moved upward, the output shaft of the winding and unwinding motor 212 is controlled to rotate forward, so as to drive the winding and unwinding roller 211 to rotate forward, and the lifting rope connected between the lifting ring 121 and the winding and unwinding roller 211 is wound and shortened, so that the translation frame 12 is stably lifted and moved upward as a whole through the lifting ring 121 located at both ends of the translation frame 12, and the supporting frame 13 located on the translation frame 12 and the worker located on the supporting frame 13 are synchronously moved upward. If the translation frame 12 and the supporting frame 13 need to be moved downward, the output shaft of the winding and unwinding motor 212 is controlled to rotate reversely, so as to drive the winding and unwinding roller 211 to rotate reversely, and the lifting rope connected between the lifting ring 121 and the winding and unwinding roller 211 is unwound and lengthened, so that the translation frame 12 is stably moved downward and falls back as a whole through the lifting ring 121 located at both ends of the translation frame 12, and the supporting frame 13 located on the translation frame 12 and the worker located on the supporting frame 13 are synchronously moved downward. Thus, the height position of the worker can be adjusted to stably move the worker to the target position.

[0051] The action mechanism of the winding and unwinding roller 211 cooperating with the lifting rope can stably operate under the driving of the winding and unwinding motor 212, so that the lifting movement stability and reliability of the translation frame 12 and the supporting frame 13 are greatly optimized, the position lifting adjustment safety of the worker is further improved, the action process of the whole winding and unwinding mechanism is smooth and efficient, the work position lifting adjustment precision of the worker is correspondingly optimized, and the operation efficiency and action precision of the whole boiler maintenance platform are correspondingly improved.

[0052] It can be understood that the winding and unwinding roller 211, the lifting rope, the lifting ring 121 and the winding and unwinding motor 212 constitute a complete winding and unwinding transmission lifting assembly, and each end of the translation frame 12 is provided with such a winding and unwinding transmission lifting assembly, and the actions of the two lifting assemblies are synchronous, so that the synchronous lifting or lowering of the two ends of the translation frame 12 is realized, and the synchronous lifting and lowering of the translation frame 12 and the supporting frame 13 arranged thereon is driven.

[0053] Generally, the lifting rope is a steel wire rope or a steel cable. Considering the stress resistance and action efficiency of the mechanism, the material of the lifting rope should be as light as possible on the basis of ensuring the bearing strength, so as to reduce the working strength and energy consumption of the winding and unwinding motor 212, and make the whole operation of the boiler maintenance platform more stable and energy-saving.

[0054] Correspondingly, further in combination with the description of the above-mentioned embodiments, Figure 2 and Figure 4As shown, the inner wall of the lifting frame 11 is provided with lifting rails 111 extending in the vertical direction, and the lifting rails 111 on any lifting frame 11 are two and symmetrically arranged on both sides of the translation frame 12. The end portions of the translation frame 12 are respectively provided with lifting guide wheels 122 capable of being fixedly rotated, and the lifting guide wheels 122 are correspondingly rolled with the lifting rails 111. The rolling fit between the lifting guide wheels 122 and the lifting rails 111 enables the main structure of the lifting frame 11 to move smoothly along the length direction of the lifting rails 111, realizes the synchronous lifting and lowering of the lifting frame 11 and the supporting frame 13 and other supporting components arranged thereon, so as to form reliable guidance and limiting of the lifting action of the lifting frame 11 by the lifting rails 111, ensure the tracking performance and action accuracy of the lifting action of the lifting frame 11, so as to safely and accurately lift the workers on the supporting frame 13 to the target height, and stably and efficiently transport the workers to the target position.

[0055] In addition, the rolling action of the lifting guide wheels 122 along the lifting rails 111 can effectively reduce the wear of the main structure of the lifting guide wheels 122 and the lifting rails 111, avoid excessive wear caused by frequent action and operation of the two, and make the corresponding component structure more durable. Figure 6 As shown, in actual application, the two end portions of the translation frame 12 can be respectively arranged with a support frame 123 having a square structure, so as to correspondingly arrange one lifting guide wheel 122 at each of the four top corners of the support frame 123, so that the stress distribution during the lifting process of the lifting frame 11 is more uniform, and the lifting action of each part of the lifting frame 11 is more synchronous, thereby further improving the lifting action efficiency and stability of the lifting frame 11. Accordingly, the lifting ring 121 can also be arranged on the top of the support frame 123, so as to avoid the interference or other adverse effects of the lifting fitting mechanism between the lifting ring 121 and the sling on the main structure of the translation frame 12, and ensure the stability of the main structure of the translation frame 12.

[0056] Please continue to refer to Figure 3Specifically, the top of the lifting frame 11 is provided with an upper fixed plate 112 and an upper connecting frame 113, the upper fixed plate 112 extends in the horizontal direction, and the upper connecting frame 113 is arranged below the upper fixed plate 112 in a one-to-one correspondence, the take-up and pay-off roller 211 is arranged on the top surface of the upper fixed plate 112, and the side of the upper connecting frame 113 protrudes and is provided with a first guide roller 213 and a second guide roller 214 adapted for the hoisting rope to wind around. The first guide roller 213 and the second guide roller 214 can cooperate with each other in parallel with the axis of the take-up and pay-off roller 211 to form a synchronous roller winding adaptation for the hoisting rope, so as to further optimize the action tracking performance of the hoisting rope during the take-up and pay-off process, and avoid the hoisting rope from loosening or mispositioning. In actual application, the first guide roller 213 and the second guide roller 214 can be arranged upstream or downstream of the take-up and pay-off roller 211 along the extension direction of the hoisting rope respectively, or the first guide roller 213 and the second guide roller 214 can be arranged upstream of the take-up and pay-off roller 211 together or arranged downstream of the take-up and pay-off roller 211 together. In principle, as long as the stable limiting and moderate support of the hoisting rope can be ensured, it is acceptable.

[0057] More specifically, the top surface of the upper fixed plate 112 is symmetrically provided with two upper connecting seats 114, the two ends of the take-up and pay-off roller 211 are correspondingly arranged in the upper connecting seats 114, and the take-up and pay-off motor 212 is arranged in one of the upper connecting seats 114 and is coaxially arranged and connected with the take-up and pay-off roller 211. The two upper connecting seats 114 can provide reliable structural support for the two ends of the take-up and pay-off roller 211, and provide a stable assembly structure basis for the take-up and pay-off motor 212, so as to ensure the stable arrangement and reliable transmission operation of the take-up and pay-off roller 211 and the take-up and pay-off motor 212.

[0058] In addition, the lifting frame 11 is provided with a plurality of reinforcing cross bars 115 extending in the horizontal direction, and the reinforcing cross bars 115 on the same lifting frame 11 are equally distributed and gap matched from top to bottom in the vertical direction. Each reinforcing cross bar 115 not only can serve as a structural reinforcing member of the lifting frame 11, but also can serve as a climbing support structure basis when necessary, so that the staff can climb to the appropriate height position of the lifting frame 11 through each reinforcing cross bar 115, thereby maintaining or replacing parts of the structure at the corresponding height of the lifting frame 11, thereby further improving the use convenience and maintenance efficiency of the boiler maintenance platform, and making the main structure more durable.

[0059] On the other hand, in combination with reference Figure 4 and Figure 5The translation frame 12 comprises two upper support rods 124 and two lower support rods 125 which are horizontally extended and parallel to each other, the two upper support rods 124 are symmetrically arranged in the horizontal direction, and the lower support rods 125 are correspondingly arranged below the upper support rods 124 one by one, and the translation base 221 is arranged between the two upper support rods 124, and the support frame 13 is connected with the translation base 221 in linkage. Correspondingly, a plurality of vertical longitudinal support rods 128 which are vertically extended can be arranged between any upper support rod 124 and the lower support rod 125 arranged below it, and each longitudinal support rod 128 is arranged equidistantly and in parallel in the horizontal direction and is gap-fitted, so as to form structural reinforcement and support between the upper support rod 124 and the lower support rod 125, thereby further optimizing the structural strength of the translation frame 12.

[0060] The translation driving assembly 22 comprises two racks 126 which are symmetrically arranged on the inner side walls of the two upper support rods 124, and further comprises two driven gears 222 which are correspondingly meshed and matched with the racks 126, and the racks 126 are extended in the horizontal direction; the translation driving assembly 22 further comprises a driving gear 223 and a translation driving motor 224 which can drive the driving gear 223 to rotate around a vertical axis, one of the two driven gears 222 is directly meshed and matched with the driving gear 223, and a reversing gear is meshed and matched between the other driven gear 222 and the driving gear 223. The translation driving motor 224, the driving gear 223, the driven gears 222 and the reversing gear are all located in the translation base 221, and the two driven gears 222 are respectively arranged on the two sides of the driving gear 223 in the horizontal direction.

[0061] When the translation driving assembly 22 is in action to drive the support frame 13 to move forward along the length direction of the translation frame 12, the output shaft of the translation driving motor 224 rotates forward to drive the driving gear 223 to rotate forward, at this time, the driven gears 222 directly meshing with the driving gear 223 and the steering gear rotate reversely synchronously with the driving gear 223, and the other driven gear 222 meshing with the steering gear rotates forward synchronously, so as to drive the two driven gears 222 to mesh with the corresponding racks 126 respectively to realize the synchronous forward force between the two driven gears 222 and the corresponding racks 126, thereby driving the two sides of the translation base 221 to move forward relative to the main structure of the translation frame 12, at this time, the support frame 13 connected to the translation base 221 moves forward synchronously; if the support frame 13 needs to move reversely, the output shaft of the translation driving motor 224 reverses to drive the driving gear 223 to reverse, at this time, the driven gears 222 directly meshing with the driving gear 223 and the steering gear rotate forward synchronously with the driving gear 223, and the other driven gear 222 meshing with the steering gear reverses synchronously, so as to drive the two driven gears 222 to mesh with the corresponding racks 126 respectively to realize the synchronous reverse force between the two driven gears 222 and the corresponding racks 126, thereby driving the two sides of the translation base 221 to move reversely relative to the main structure of the translation frame 12, at this time, the support frame 13 connected to the translation base 221 moves reversely synchronously.

[0062] Thus, by using the gears adapted to the translation driving motor 224 and the racks 126, the bidirectional driving of the translation base 221 is formed, the horizontal reciprocating movement of the translation base 221 is realized, thereby driving the support frame 13 and the workers on the support frame 13 to move to the target position along the horizontal direction. The gear transmission mechanism is stable and reliable in transmission, has high transmission efficiency, and can make the boiler maintenance platform more safe and efficient in the horizontal direction transportation process of the workers on the support frame 13.

[0063] On this basis, the following are mainly referred to Figure 7As shown, the supporting frame 13 comprises a main supporting plate 132 fixed on the top of the translation base 221 and extending in the horizontal direction, and a side supporting frame 133 located on the side of the translation frame 12 and extending in the vertical direction, the top end of the side supporting frame 133 is connected to the side of the main supporting plate 132. The outer side wall of the lower supporting rod 125 is concavely provided with a lower guide groove 127 extending along the length direction thereof, and the side supporting frame 133 is convexly provided with a lower sliding block 134 corresponding to the lower guide groove 127 and slidingly fitted thereto on the side wall of the lower supporting rod 125. The lower sliding block 134 is slidingly fitted in the lower guide groove 127, so that the lower guide groove 127 can reliably limit and guide the movement path of the supporting frame 13 during the horizontal movement of the supporting frame 13 along the length direction of the translation frame 12, avoiding dislocation of the supporting frame 13 during movement, ensuring the horizontal movement tracking of the supporting frame 13, and improving the action accuracy, so that the horizontal conveying work of the worker on the supporting frame 13 is more accurate and efficient.

[0064] Further, the bottom end of the side supporting frame 133 is convexly provided with a secondary supporting plate 135 extending in the horizontal direction and facing away from the side of the lower supporting rod 125, and the secondary supporting plate 135 is arranged in position with the main supporting plate 132. The supporting frame 13 further comprises a side supporting plate 136 protruding from the top surface of the main supporting plate 132, and the side supporting plate 136 is located on the opposite side of the secondary supporting plate 135 in the horizontal direction with the translation frame 12 as the reference, that is, the side supporting plate 136 and the secondary supporting plate 135 are located on the two sides of the translation frame 12. The safety belts 131 are two, one of which is horizontally connected to the top surface of the main supporting plate 132, and the other of which is horizontally connected to the side wall of the side supporting plate 136 facing the secondary supporting plate 135. The main supporting plate 132 as the main supporting component can directly contact the buttocks of the worker; on this basis, the worker can step on the secondary supporting plate 135 with both feet to form support for the lower limbs, and at the same time the worker can lean on the side supporting plate 136 for the side support of the trunk, so as to form overall support and moderate limitation of the worker by the cooperation of the main supporting plate 132, the side supporting plate 136 and the secondary supporting plate 135, not only optimizing the stress distribution of the supporting frame 13 when carrying the worker, but also helping the worker to maintain body balance and avoid falling from the main structure of the supporting frame 13; in combination with the two safety belts 131 respectively moderately binding and limiting the upper body of the worker at the corresponding position of the side supporting plate 136 and the lower body of the worker at the corresponding position of the main supporting plate 132, the position of the worker on the supporting frame 13 can be further ensured to be constant, avoiding dislocation or falling of the worker during the lifting, horizontal movement or maintenance and treatment of the target public health during the movement of the supporting frame 13, so as to further ensure the safety of the worker during the maintenance and treatment work on the boiler maintenance platform.

[0065] In actual application, the specific binding arrangement of the safety belt 131 and the mounting mode thereof can refer to the safety belt arrangement structure applied to large mechanical equipment or vehicles in the prior art, and the technical details thereof are not revolutionarily reformed in the present scheme. The person skilled in the art can directly refer to the corresponding adjustment and adaptation of the conventional technology, and the present text will not be repeated.

[0066] In addition, the boiler maintenance platform further comprises a controller and an operation panel 137 in communication connection with the controller, and the operation panel 137 is located on one side of the support frame 13. In actual application, the controller can be a PLC (Programmable Logic Controller) to communicate and cooperate with the electric control action mechanisms such as the winding and unwinding motor 212 and the translation driving motor 224, forming a reliable electric control system. Correspondingly, the operation panel 137 is arranged on one side of the support frame 13, so that the workers located on the support frame 13 can control the start-stop and operation mode of each winding and unwinding motor 212 and translation driving motor 224 by themselves, so as to achieve the purpose of adjusting the lifting and translation of the work station by themselves, thereby eliminating the need for additional workers to control the action mechanisms of the boiler maintenance platform, thereby greatly simplifying the personnel configuration required when the boiler maintenance platform is working, reducing the corresponding manpower demand of the boiler maintenance and repair work, and making the implementation process of the boiler maintenance and repair work more simple and efficient.

[0067] In addition, combined with reference Figure 8 As shown, the walking mechanism is generally a universal wheel 101 arranged at the bottom of each top corner of the rack 10, so as to move the whole boiler maintenance platform to the target position. Generally, the rack 10 is a horizontally arranged frame structure, and a plurality of horizontally extending reinforcing beams 102 or reinforcing ribs can be arranged inside the frame structure of the rack 10, so as to further improve the structural strength of the rack 10, optimize its stress resistance and load capacity, so that the overall structure of the boiler maintenance platform is more solid and reliable, and the workers using the boiler maintenance platform to implement the boiler maintenance and repair work are more secure.

[0068] In summary, the boiler maintenance platform provided in the present application can reliably fix the worker on the support frame by using the positioning and binding of the safety belt during the operation and use process of the boiler maintenance platform, and then the worker can be transported to the target work surface of the boiler to be maintained by moving the support frame to the target position along the extension structure of the translation frame by the translation driving assembly, so that the worker can implement the corresponding maintenance treatment operation on the target work station. Then the worker can implement the corresponding maintenance treatment operation on the target work station, and after the operation is completed, the worker can be transported to the corresponding position of the next work surface by moving the translation frame and the support frame to the initial work station or the corresponding position of the next work surface by the lifting driving assembly and the translation driving motor, respectively. If the maintenance operation needs to be performed on another boiler equipment or a work station that cannot be matched by the action mechanism of the boiler maintenance platform, the boiler maintenance platform can be moved to the next boiler equipment or target work station by the walking mechanism, and then the worker on the support frame can be transported to the target work surface by the coordinated action of the lifting driving assembly and the translation driving assembly, so that the corresponding maintenance operation can be performed. If the current operation is completed and the action components of the boiler maintenance platform are reset, the safety belt can be opened to release the binding of the worker on the support frame, so that the worker can leave the boiler maintenance platform. It is not difficult to see that the operation and use process of the boiler maintenance platform is convenient and efficient, and the worker can be safely and accurately transported to the target work station by the boiler maintenance platform without relying on external equipment such as a crane or a forklift, so that the corresponding boiler maintenance operation can be performed to meet the boiler maintenance requirements under different working conditions. The worker only needs to sit stably on the support frame during the moving process, thereby effectively reducing the labor intensity of the worker and making the corresponding boiler maintenance operation more simple and easy.

The principles and implementation methods of the present application are described by applying specific examples in this paper, and the above examples are only used to help understand the method of the present application and its core idea. It should be noted that for ordinary skilled persons in the technical field, some improvements and modifications can be made to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
