Description

Technical Field

[0001] The present invention relates to the technical field of boiler modification equipment, and in particular to a large-scale unit boiler wall temperature modification system and a use method thereof. Background Art

[0002] In large-scale thermal power projects, the stability of boiler wall temperature is directly related to the safe and stable operation of the boiler, the economic benefits of the power plant, and the sustainable development of the enterprise. With the increasing number of boiler wall temperature control cables and the heavy construction workload, the quality of boiler wall temperature installation, cable laying and wiring process has become the focus of project management and control.

[0003] To increase the safety of equipment operation, a boiler wall temperature detection system needs to be installed on the boiler of a large unit during construction and renovation (the construction process can refer to the large unit boiler wall temperature construction method disclosed in Chinese invention patent No. CN110822405B). The boiler wall temperature detection system consists of temperature measuring parts, heat collecting blocks, columns, brackets, and cables (the boiler wall temperature monitoring system monitors the wall temperature in real time through thermocouples or other temperature sensors installed at key positions on the boiler heating surface, and transmits the temperature to the control center through a data acquisition system). These components are usually installed in the key heating parts of the boiler, most of which are located at high places; during actual construction and renovation, the layout of the entire system is completed through cutting, welding, grinding and other operations.

[0004] During the construction and renovation process, due to operational needs, operators are required to first reach a high place (i.e., the location of the key heating parts of the boiler located outside or inside the boiler) and then carry out operations; due to different types and sizes of boilers, the ways for operators to reach high places are also relatively diverse, generally ladders, scaffolding, aerial work vehicles, hanging baskets, etc.; but the work site environment is complex, and the use of related equipment for carrying operators is severely restricted, especially when non-exterior operations are required. Due to the small working space, the use of traditional climbing methods generally has the problems of difficulty in entering (for example, it is difficult for lifting work vehicles to enter), difficulty in movement (the space available for activities in the environment is small, it is difficult to transport operators to the most suitable target position, and the height of the platform that can be provided is relatively low), and cumbersome support body layout (the assembly and layout of scaffolding, etc. is inefficient and labor-intensive).

[0005] Therefore, there is a need for a large-scale boiler wall temperature modification system that is easy to use, easy to assemble and disassemble, simple to move, and has strong applicability (suitable for boilers of various specifications, both inside and outside the boiler). Compared with operations such as manually building scaffolding on demand, it has high operating efficiency and low labor intensity and is suitable for the installation, maintenance and modification of boiler wall temperature detection systems.

[0131] Preferably, the bottom splicing rod 910 is a manual or electric telescopic rod.

[0132] Preferably, more than 10 locations for installing the bottom splicing rod 910 are positioned on the edge of the supporting base plate 110 to adapt to different installation environments.

[0133] Preferably, one or more universal wheels are positioned at the bottom of the bottom splicing rod 910 .

[0136] In order to further improve the stability of the operation process of the system of the present application, the embodiment of the present application optimizes and improves the structure of the splicing column constituting the splicing bearing column 500 and the structure of the conveyor belt assembly 720 on the basis of the above embodiment, and adapts the structure of the column lifting assembly. Specifically,

[0137] The splicing column is composed of three combined pipes 550 and a plurality of connecting frames 560;

[0138] like Figure 12 and Figure 13 As shown (the structure of the combined tube 550 is shown in the figure only in its basic outline, and its bottom groove, top protrusion and central cavity are not shown), the combined tube 550 is a hard round rod, at least one of the three combined tubes 550 is provided with a positioning pin hole 540, and at least one is provided with a matching groove 530; the three combined tubes 550 are parallel to each other and are equally spaced from each other;

[0139] The connecting frame 560 is a herringbone plate or rod, fixed to the side wall of the combined tube 550, fixing the three combined tubes 550 together;

[0140] Two or three rows of limit blocks 730 are positioned on the conveyor belt assembly 720, and every two or three limit blocks 730 correspond to a splicing column;

[0141] The inner ring profiles of the first restraining ring 220 and the second restraining ring 230 match the cross-sectional profile of the splicing column.

[0142] The splicing column composed of three combined tubes 550 and multiple connecting frames 560 has better stability and lighter weight than a single tubular splicing column.

[0143] Example 4

[0144] During the maintenance process, a large number of tools and accessories need to be replaced, but the platform space is limited. When replacing tools and accessories, the workers need to constantly go back and forth between the ground and the platform, which brings great inconvenience to the maintenance work. Carrying the tools and accessories directly on the standing platform 420 will not only increase the load of the standing platform 420 and affect the stability of the system, but also occupy the operator's activity space, which brings certain obstacles to the operation. To address the above problems, the embodiment of the present application adds a tool accessory lifting assembly for carrying tools and accessories on the basis of the above embodiment, which is specifically:

[0145] like Figure 14 and Figure 15 As shown, the tool accessory lifting assembly includes a carrier 010, a counterweight 020, a rotating movable body 030, a load-bearing ladder and a storage frame 040;

[0146] The carrier 010 is fixed on the side wall of the rotating plate 441 and is arranged close to the manned platform assembly. It is a plate, block or frame structure and plays the role of bearing connection.

[0147] The counterweight 020 is also fixed on the side wall of the rotating plate 441 to balance the load brought to the splicing bearing column 500 by the presence of other components of the tool accessory lifting assembly;

[0148] The rotating moving body 030 is a horizontally arranged cylindrical roller with a built-in motor, which rotates under the control of the control unit to retract and release the load-bearing soft ladder;

[0149] The top of the load-bearing soft ladder is fixed on the rotating movable body 030 and is used to carry the positioning storage frame 040;

[0150] The storage frame 040 is a box structure with an open top, and there are multiple of them, which serve as a container and can be detachably fixed on the load-bearing ladder.

[0151] Furthermore, the load-bearing soft ladder includes two load-bearing belts 031 and multiple connecting cross bars 032; the load-bearing belt 031 is a long soft belt, one end of which is fixed to the rotating movable body 030; the connecting cross bars 032 are hard rods, which are arranged horizontally, with both ends fixed to the load-bearing belt 031, and the distance between them is equal; when the load-bearing belt 031 is stretched, the connecting cross bars 032 are perpendicular to the load-bearing belt 031; the storage frame 040 is detachably fixed to the connecting cross bars 032.

[0152] When tools and accessories need to be retrieved, people on the ground cooperate with the tool and accessories lifting assembly to deliver the tools and accessories. Because the tool and accessories lifting assembly is set close to the splicing bearing column 500, the non-vertical downward pressure applied to the splicing bearing column 500 is less, and the load on the splicing bearing column 500 is also relatively less.

[0153] Example 5

[0154] In order to reduce the involvement of personnel and improve the convenience of using the tool accessory lifting assembly, the embodiment of the present application optimizes and improves the structure of the rotating moving body 030 based on the above embodiment, specifically:

[0155] like Figure 16 and Figure 17 As shown, the rotating moving body 030 includes a rotating plate 051, a carrier ring 052 and a central axis 053;

[0156] The rotating plates 051 are two hard circular plates, both arranged longitudinally. The two plates are fixed together by a central axis 053. The ends of the central axis 053 are respectively fixed to the two rotating plates 051, and the axis coincides with the axis of the rotating plates 051. The length of the central axis 053 is greater than the length of the storage frame 040.

[0157] The carrier rings 052 are hard rings, two in number, corresponding one to each rotating plate 051, fixed on the side wall of the rotating plate 051, coaxial with the rotating plate 051 and arranged close to the edge of the rotating plate 051;

[0158] The carrier ring 052 is used to carry and position the carrier belt 031. The carrier belt 031 is always tightly attached to the carrier ring 052. The radius of the carrier ring 052 is greater than 1.4 times the height of the storage frame 040.

[0159] The carrier belt 031 is provided with holes at equal intervals, and the carrier ring 052 is provided with protrusions at equal intervals that match the holes in the carrier belt 031. The protrusions on the carrier ring 052 are embedded in the holes in the carrier belt 031 that are in close contact with it. Due to the presence of the protrusions and holes, the carrier belt 031 will not slip on the carrier ring 052 (the carrier ring 052 is equivalent to the gear ring).

[0160] One of the rotating plates 051 is connected to the carrier frame 010 and rotates around its own axis, and is rotated by the motor; the storage frames 040 are all connected to the connecting cross bar 032 and rotate around the axis of the connecting cross bar 032.

[0161] The load-bearing ladder is placed on the rotating movable body 030, and the load-bearing belt body 031 is close to the load-bearing ring 052; the tools and accessories are placed in different storage frames 040; when they need to be taken, the rotating movable body 030 is controlled to rotate the mobile storage frame 040.

[0162] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various modifications and variations are readily apparent to those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
