A connecting plate 603 is welded on one side of the central axis. The horizontal length of the bottom plate 14 set by the lifting platform is smaller than the width inside the furnace of most thermal power plants. When the lifting platform is installed inside the furnace, the maintenance personnel use the lifting platform to carry out maintenance During the maintenance process, the maintenance personnel can use the side plate 5 and the upper plate 602 to adjust the horizontal length of the steel horizontal frame 1 in a disguised form. During the maintenance process, the existing length of the steel horizontal frame 1 cannot support the left When the wall is inspected and repaired, the operator first holds the bolts inserted between the upper plate 602 and the protective frame 3 and pulls them outward, and then pulls out the bolts completely, and then holds the handle above the inner side of the upper plate 602, because the side plate 5 is connected to the The first 4 phases are hinged. At this time, the upper plate 602 is in a reversible state. Then start the hydraulic telescopic rod 1 601 to adjust the position of the upper plate 602 by using the expansion and contraction of the hydraulic telescopic rod 1 601.

The cross-section of the auxiliary support plate 9 is viewed as a rectangle. During the forward and reverse rotation of the forward and reverse motor 1103, the main shaft on the right side of the forward and reverse motor 1103 can drive the belt 1102 to rotate, and the pulley 1101 will follow the rotation of the belt 1102. At this time, the thickened screw rod 8 will also carry out forward and reverse rotation under the action of the pulley 1101. During the process of forward and reverse rotation of the thickened screw rod 8, the threaded sleeve 7 can be rotated on the thickened screw rod 8. The outer side of the lifting platform moves left and right, so that the auxiliary support plate 9 can also move left and right. The auxiliary support plate 9 can move left and right, so that during the use of the lifting platform, the auxiliary support plate 9 can be adjusted according to the needs of maintenance personnel. It is supported by the telescopic assembly 6 at the right end, and the lower middle part of the steel horizontal frame 1 is provided with a lifting frame 13, and the inner side of the lifting frame 13 is equipped with a hydraulic telescopic rod 2 15, and the bottom of the lifting frame 13 is hinged with a bottom plate 14, and the bottom plate The cross section of 14 is viewed as a rectangle from above, the top, front and rear ends of the lifting frame 13 are provided with fixing components 10, and the upper left end of the lifting frame 13 is welded with a fixing bracket 12, the fixing component 10 includes a mounting plate one 1001 and a mounting plate two 1002, and Mounting plate 2 1002 is arranged on the top of mounting plate 1 1001. The lifting platform is mainly composed of steel horizontal frame 1, fixed plate 2, fixed assembly 10, lifting frame 13, base plate 14 and hydraulic telescopic rod 2 15 and other parts. During the use of the boiler furnace, when it is necessary to overhaul the interior of the furnace, the operator first uses a tool to rotate the screws on the inside of the installation plate 1001 and the installation plate 2 1002, and then the belt 1102 and the pulley 1101 and the positive The main shaft on the right side of the reversing motor 1103 is separated. At this time, the steel horizontal frame 1 and the lifting frame 13 are in a detachable state. After the hydraulic telescopic rod 2 15 shrinks to the maximum extent, the height of the lifting frame 13 can be reduced to the minimum at this time. After the operator disassembles the lifting platform into two parts and transports it into the furnace through the inspection channel of the boiler of the thermal power plant, Using the above-mentioned opposite method again, after the lifting platform is reassembled together, the maintenance personnel can use the lifting platform to adjust their own height inside the furnace, so as to facilitate the maintenance of the furnace.

To sum up, the lifting platform that can cooperate with boiler furnaces of different sizes, when in use, first of all, as shown in Figure 1, Figure 4 and Figure 5, the lifting platform is mainly composed of a steel horizontal frame 1, a fixed plate 2, and a protective frame 3 , fixed assembly 10, lifting frame 13, bottom plate 14 and hydraulic telescopic rod 2 15 and other parts. During the use of the boiler furnace of a thermal power plant, when it is necessary to overhaul the inside of the furnace, the operator first uses tools to install the installation plate 1001 After rotating all the screws installed on the inside of the mounting plate two 1002, the belt 1102 is separated from the main shaft on the right side of the belt pulley 1101 and the forward and reverse motor 1103. In the separated state, the operator will separate the steel horizontal frame 1 and the lifting frame 13, and the lifting platform can be divided into two parts, and then start the hydraulic telescopic rod 2 15, and shrink the hydraulic telescopic rod 2 15 to the maximum extent. At this time, the height of the lifting frame 13 can be reduced to the minimum. After the operator disassembles the lifting platform into two parts through the maintenance channel of the thermal power plant boiler and transports it into the furnace, then adopts the above-mentioned opposite method to reinstall the lifting platform. After being assembled together, the belt 1102 is reinstalled back to the original position, and the maintenance personnel stand on the top of the fixed plate 2, and then manipulate the hydraulic telescopic rod 2 15, and use the expansion and contraction of the hydraulic telescopic rod 2 15 to adjust their own height , when the horizontal length available for walking above the steel horizontal frame 1 can support maintenance personnel to perform maintenance on the left and right walls of the furnace, the telescopic component 6 can cooperate with the protective frame 3 to protect the maintenance personnel. When the existing length of the transverse frame 1 cannot support the maintenance personnel to perform maintenance on the inner wall of the furnace, as shown in Figure 2 and Figure 3, the maintenance personnel first hold the bolt inserted between the upper plate 602 and the protective frame 3 and pull it outwards After the bolt is completely pulled out, hold the handle above the inside of the upper plate 602. Because the side plate 5 is hinged with the connector 4, the upper plate 602 is in a reversible state at this time. According to the distance between the steel horizontal frame 1 and the left wall of the furnace, the position of the upper plate 602 is adjusted according to the expansion and contraction of the hydraulic telescopic rod-601. After the maintenance personnel adjust the upper plate 602 to a suitable position, start the forward and reverse motor 1103 During the forward and reverse rotation of the forward and reverse motor 1103, the main shaft on the right side of the forward and reverse motor 1103 can drive the belt 1102 to rotate, and the belt pulley 1101 will rotate with the rotation of the belt 1102. At this time, the screw rod 8 is thickened Under the effect of belt pulley 1101, also can carry out positive and negative rotation, and thickening screw mandrel 8 is in the process of forward and reverse rotation, and threaded sleeve 7 just can move left and right on the outside of thickening screw mandrel 8, and auxiliary support plate 9 can also be Move left and right, and then use the rotation of the forward and reverse motor 1103 to move the threaded sleeve 7 to the leftmost side of the thickened screw rod 8. At this time, the auxiliary support plate 9 can be stretched out from the left end of the steel horizontal frame 1 for maintenance. The person then holds the handle and pushes it to the left. During the pushing process, the upper plate 602 can be flipped to the left until the connecting plate 603 and the upper surface of the auxiliary support plate 9 are pushed together, and the upper plate 602 is in a horizontal position. At this time, the maintenance personnel can step on the upper surface of the side plate 5 and the upper plate 602 to overhaul the left wall of the furnace. At the same time, when the right wall of the furnace is overhauled, the auxiliary support plate will also be replaced in the same way as above. 9.
