Detailed Description

In the figure, the folding platform of the utility model consists of a basic frame 1, a left fence 2, a left door 5, a right fence 10, a right door 6 and a turnover pedal 7, wherein all the parts are hinged together, when the folding platform is unfolded, relevant locking bolts are pulled out, and the doors, the fences and an expansion bottom pedal are sequentially and manually unfolded and inserted with the bolts.

The left rail 2 and the right rail 10 are respectively hinged with the base frame 1 through a hinge shaft c14, a hinge shaft d15, a hinge shaft g18 and a hinge shaft h 19; the turnover pedal 7 is hinged with the base frame 1 through a hinge shaft m23 and a hinge shaft n 24; the left door 5 is hinged with the left rail 2 through a hinge shaft a3 and a hinge shaft b4, the right door 6 is hinged with the right rail 10 through a hinge shaft e16 and a hinge shaft f17, and bottom support limiting grooves 12 are respectively processed on the left rail 2 and the right rail 10. The top of the right door 6 is provided with a bolt d20 and a bolt e21, the bottom of the right door 6 is provided with a bolt f22, and two ends of the outer side of the turnover pedal 7 are respectively provided with a bolt c 13. Under the folding state of the maintenance platform, the bolt d20 is inserted into the top of the left door 5, the bolt e21 is inserted into the top of the left rail 2, the bolt f22 is inserted into the bottom of the left door 5, the bolt c13 is inserted into two sides of the basic frame 1, and each movable joint of the maintenance platform is reliably locked through the 5 bolts. The top of the right door 6 is provided with a clamping plate pin assembly 11, the clamping plate pin assembly 11 and the left door 5 are locked together through a bolt under the unfolded state of the maintenance platform, and the bottoms of the left door 5 and the right door 6 are locked together with the turnover pedal 7 through bolts a8 and b 9.

During unfolding operation, the pin d20, the pin e21 and the pin f22 are firstly pulled out in sequence, as shown in fig. 3, the right rail 10 and the right door 6 are opened, then the left rail 2 and the left door 5 are opened as shown in fig. 4, then the pin c13 is pulled out, as shown in fig. 5, the turnover pedal 7 is turned down, the left end and the right end of the turnover pedal 7 respectively fall into the bottom support limiting grooves 12 on the left rail 2 and the right rail 10, after an operator enters the maintenance platform, the left door 5 and the right door 6 are finally closed, the left door and the right door of the maintenance platform are locked through the top clamping plate pin assembly 11, the pins, the bottom pins a8 and the pin b9, and folding operation is the reverse process of unfolding operation.
