Problems solved by technology
However, the height of large-scale boilers is usually relatively high, and manual maintenance must be carried out in the form of climbing with the help of corresponding escalators or the ladders that come with the boiler. Fixed, it is difficult to adjust the climbing angle. Even if the angle can be adjusted, it is difficult to solve the problem that the height of the bottom step is too high after adjustment, which makes it difficult to climb manually

The invention relates to an extension type ladder frame special for a large boiler. The extension type ladder frame comprises a main frame body, two parallel main connecting plates are hinged to the upper part of the main frame body, fixed ladder plates are uniformly distributed between the two main connecting plates in the vertical direction, and the left end and the right end of each fixed ladder plate are correspondingly hinged to the two main connecting plates; a slot is formed in the lower part of each main connecting plate, a left linkage plate is slidably mounted in the slot on the left side, and a right linkage plate is slidably mounted in the slot on the right side; a plate control assembly is mounted on the left linkage plate; and a locking assembly is mounted on the right linkage plate. According to the extension type ladder frame, the inclination angles of the multiple fixed ladder plates can be automatically controlled and adjusted, the fixed ladder plates can be controlled to rotate and be fixed after adjustment, the effect of conveniently raising workers is achieved, the extension type ladder frame is suitable for manual climbing in different environments, and parts on a boiler can be indirectly and conveniently maintained manually.
Description
technical field [0001] The invention relates to the field of mechanical production, in particular to a special extended ladder frame for large boilers. Background technique [0002] The safety valve, vent hole, water level controller, main steam valve, gas saving gas and other related important components are placed on the top of the large boiler. After a period of use each time, these components need to be manually repaired . However, the height of large-scale boilers is usually relatively high, and manual maintenance must be carried out in the form of climbing with the help of corresponding escalators or the ladders that come with the boiler. Fixed, it is difficult to adjust the climbing angle. Even if the angle can be adjusted, it is difficult to solve the problem that the height of the bottom step is too high after adjustment, which makes it difficult to climb manually. Contents of the invention [0003] In order to overcome the two defects in the above-mentioned tec...
