Problems solved by technology
[0003] At present, the traditional work platform is generally in the form of a work bucket directly welded with steel pipes. Its height reaches more than 1100mm, and it is difficult to control the height within the height limit. Moreover, the installation space is large, resulting in super high work locomotives, so it cannot be used well. Adapt to the use of railway work tools

Embodiment Construction
[0034] Below in conjunction with accompanying drawing of description, the present invention will be further described.
[0035] Such as Figure 1 to Figure 7 As shown, a telescopic and folding work platform includes a work platform bottom frame 10 , side brackets 20 , side upper doors 30 and telescopic handrails 40 .
[0036] Such as Figure 8 As shown, the working platform bottom frame 10 includes a platform bottom frame 1 , two axial side frames 2 and two radial side frames 3 which are vertically connected to the platform bottom frame 1 .
[0037] The platform bottom frame 1 includes a rectangular frame and a tiled pedal 11 in the frame. The rectangular frame is formed by welding rectangular steel pipes and includes two axial lower vertical tubes 12 and two radial lower horizontal tubes 13; The axial side frame 2 includes a bottom frame vertical tube 21 perpendicular to the lower vertical tube 12, an upper vertical tube 22 parallel to the lower vertical tube 12, and an axi...

The invention discloses an expandable and foldable work platform which comprises a work platform bottom frame, side brackets, side upper doors and flexible handrails, wherein through the rotatable connections between the side brackets and the work platform bottom frame, the rotatable connections between the side upper doors and the side brackets, the sliding connections between the flexible handrails and the side brackets, the sliding connections between the flexible handrails and the side upper doors, and the mechanical limiting and reinforcing of the components, the expansion and folding of the work platform are realized, so that the height of the work platform is low enough in a folded state and meets the work requirement in an unfolded state, namely, the height is 500 mm or below in the folded state and is 1100 mm or above in the unfolded state, so as to solve the problem that the work is inconvenient to carry out by several workers with multiple devices simultaneously as the conventional work platform is relatively large in mounting space, the work haulage motor is ultrahigh, and the traditional work platform is relatively small in bearing capacity. The expandable and foldable work platform has the advantages of being simple in structure, easy to dismount, convenient to operate, safe, reliable and small in mounting space, and is especially suitable for railway work implements.
Description
technical field [0001] The invention relates to an operation platform, in particular to a retractable and foldable operation platform, which belongs to the operation platform for railway operation tools. Background technique [0002] With the development of the railway industry, more and more railway work tools are put into use. The railway work tools can be arranged on the top of the train locomotive, which requires the installation height of the work platform to be low enough to ensure that the entire work machine can maintain its own rigidity and Under the premise of strength, it avoids the problem of super height. [0003] At present, the traditional work platform is generally in the form of a work bucket directly welded with steel pipes. Its height reaches more than 1100mm, and it is difficult to control the height within the height limit. Moreover, the installation space is large, resulting in the super high work locomotive, so it cannot be well installed. Adapt to th...
