The main guard rail 12 preferably comprises two longitudinal beams fixed in parallel to the rear side edges of the main standing plate 11, a cross beam connected between the two longitudinal beams, and arc-shaped beams fixed on both sides of the longitudinal beams. In addition, the rear side edge of the main station riser 11 is provided with a side baffle, which is favorable for preventing tools and the like on the main station riser 11 from falling, thereby improving the safety. To reduce the weight of the main frame 1, the main standing plate 11 is provided with a number of weight reducing holes. Further, the main frame 1 is made of an aluminum alloy in order to further reduce the weight of the main frame 1 while ensuring the strength of the main frame 1. A protective door is arranged on one side of the main frame 1 far away from the main protective link so as to allow operators to enter and exit the main frame 1. Of course, the structure of the main frame 1 is not limited thereto.
Based on the current view of fig. 1, the left turnover frame 2 and the right turnover frame 3 are hinged to the left and right sides of the main frame 1 respectively, so as to expand the working space according to the external environment, thereby being beneficial to improving the adaptability. And because only the left overturning frame 2 and/or the right overturning frame 3 need to be overturned when the working space is expanded, the operation is convenient. In this embodiment, to promote versatility, the left roll-over frame 2 and the right roll-over frame 3 are identical in structure. However, it should be noted here that the outer dimensions of the left tilting frame 2 and the outer dimensions of the right tilting frame 3 may preferably be different, and that the outer dimensions of the left tilting frame 2 are smaller than the outer dimensions of the right tilting frame 3, as seen in the current view of fig. 3, in order to achieve an adjustment of the working space of various dimensions. Of course, it is not limited thereto.
In this particular embodiment, the left roll-over frame 2 preferably includes a left standing board 21, a left guard rail 22, and a left stop assembly 23.

In this particular embodiment, the ceiling bracket 42 preferably includes a ceiling guard 41 and a ceiling bracket 42 mounted between the ceiling guard 41 and the main rail 12 to support the ceiling guard 41. The ceiling guard 41 is preferably a square flat plate having an area substantially equal to the area of the main station riser 11.
To adapt to the working height of the external space, one end of the ceiling bracket 42, which is close to the main guard rail 12, is connected with the main guard rail 12 in a telescopic manner, which is beneficial to further improving the adaptability. In order to stably support the ceiling guard 41 by the ceiling bracket 42, a limiting clamp 43 for selectively limiting the position of the ceiling bracket 42 relative to the main guard 12 is provided at the connection part of the ceiling bracket 42 and the main guard 12, the limiting clamp 43 is mounted on the main guard 12, when the ceiling bracket 42 drives the ceiling guard 41 to a preset height, the clamp teeth of the limiting clamp 43 are abutted against the ceiling bracket 42, and the clamp teeth are locked to the ceiling bracket 42 by the clamp arms of the limiting clamp 43, so that the ceiling bracket 42 is fixed relative to the main guard 12, and of course, the limiting mode is not limited to this, and the invention can still achieve the aim by adopting elastic pins, pin holes and other modes instead.
To improve the protection reliability of the ceiling guard 41, the ceiling guard 41 is hinged to the top of the ceiling bracket 42 so as to remove the ceiling guard 41 when necessary, but an anti-rotation support plate is provided on the side of the ceiling bracket 42 close to the main frame 1, and when the ceiling guard 41 is located right above the main frame 1, the anti-rotation support plate limits the ceiling guard 41 to turn over relative to the ceiling bracket 42, so that the ceiling guard 41 has enough strength to resist external foreign matters so as not to protect the ceiling guard 41. The ceiling guard 41 can only be rotated clockwise up around the top of the ceiling bracket 42 from the current position, and cannot be rotated counterclockwise down from the current position, taking the current view of fig. 1 into consideration.
Preferably, in order to achieve light weight, the protective ceiling 4 is also made of aluminum alloy, so that the weight of the protective ceiling 4 is reduced under the premise of ensuring the supporting strength, which is beneficial to improving the bearing capacity.
In addition, the present invention further includes a lighting bracket 5 provided on the main standing board 11 so as to support the lighting device. In this particular embodiment, the lighting fixture 5 includes a lighting column and a U-shaped bracket welded to the top of the lighting column, but the structure of the lighting fixture 5 is not limited thereto.
In summary, the arch work platform provided by the invention comprises a main frame 1, a left turning frame 2, a right turning frame 3 and a protective ceiling 4. The left overturning frame 2 and the right overturning frame 3 are overturned relative to the main frame 1 so as to enlarge or reduce the working platform, so that the working platform is suitable for a working space within a certain range, and the adaptability is improved; the protection top can effectively block external foreign matters from falling into the operation space, and is favorable for improving safety. Therefore, the arch work platform provided by the invention is beneficial to improving the adaptability and the safety.
