Description

Technical Field

[0001] The utility model relates to the technical field of assembled ladders, in particular to an assembled ladder. Background Art

[0002] In order to meet the needs of human life, ladders are updated with the development of productivity and new materials. Aluminum alloy ladders are made of high-strength aluminum alloy materials, which are characterized by light weight and high strength. It greatly facilitates the work intensity of construction workers.

[0003] At present, the silencers of containerized generator sets produced by the domestic generator industry are mostly installed on the top of the box. When leaving the factory, the silencers are usually disassembled and transported together with the box. After arriving at the project site, they are installed on site. Installation and subsequent maintenance require climbing to the top of the box with a ladder. In the past, the ladders on the container boxes were mostly welded to the box frame. This installation method not only causes welding deformation, but also because the ladder is welded to the box as a whole, the outer surface of the ladder covered by the box may not be processed during surface treatment, reducing the production efficiency of the staff. Utility Model Content

[0006] As a further improvement of the above solution, the number of the bolts 1 is set to be several, and the several bolts 1 are located on the inner surfaces of the ladder panel and the back panel, and the back panel is located behind the ladder panel.

[0007] As a further improvement of the above solution, the upper top plate is located above the lower top plate.

[0008] Through the above technical scheme, the user can use a pair of bolts to install the ladder panel and the back panel. The back panel can be installed on the back of the ladder panel by bolt one, and the bolt one is tightened together to prevent loosening during use. Above the ladder panel and the back panel, in order to prevent rain from falling into the inside of the ladder panel and the back panel due to external weather reasons during use, the upper top plate can protect the inside, and the lower top plate below can connect the ladder panel and the back panel. When the lower top plate contacts the ground, the stability of the device can be better guaranteed, and the water below can be prevented from entering the inside of the device from bottom to top to damage the internal device. Bolt two is threadedly installed on the inner surface of the square tube and the outer frame plate, so that the outer frame plate is installed on the front side of the ladder panel, and the square tube is inside the outer frame plate. When the user steps on the outer frame plate, the inner square tube can provide support for the outer frame plate to prevent the outer frame plate from bending due to excessive weight of the user.

[0009] As a further improvement of the above solution, the number of the outer frame plates is set to be several, and the inner walls of several of the outer frame plates are located on the front side of the ladder panel.

The back panel can be installed on the back of the ladder panel by the bolt first, and the bolts are fastened together to prevent loosening during use. Above the ladder panel and the back panel, in order to prevent rain from falling into the inside of the ladder panel and the back panel due to external weather reasons during use, the upper top plate can protect the inside, and the lower top plate below can connect the ladder panel and the back panel. When the lower top plate contacts the ground, the stability of the device can be better guaranteed, and the water below can be prevented from entering the inside of the device from bottom to top to damage the internal device. The bolt second is threadedly installed on the inner surface of the square tube and the outer frame plate, so that the outer frame plate is installed on the front side of the ladder panel, and the square tube is inside the outer frame plate. When the user steps on the outer frame plate, the inner square tube can provide support for the outer frame plate to prevent the outer frame plate from bending due to excessive weight of the user.
