Detailed Description

As shown in fig. 1-3, a foldable construction platform with adjustable height comprises a telescopic plate 1 erected on a base surface by four telescopic vertical rods 2 arranged in a matrix shape, wherein the telescopic vertical rods 2 are provided with locking devices; the telescopic vertical rod 2 is a main bearing part, the bearing capacity and the strength of the locking device of the telescopic vertical rod can meet the requirements of workers supporting the telescopic plate 1 and working above the telescopic plate, a plurality of steel sections of loop bars are preferably selected, bolt holes are arranged on the loop bars at intervals along the length direction, the locking is carried out through bolts, the number of the sections of the telescopic vertical rod 2 is as small as possible, and the sections are made into two sections as possible.

Two sets of cross braces 3 are oppositely arranged on the telescopic vertical rod 2, and a rotating shaft between two inclined rods of each cross brace 3 is parallel to the plate surface of the telescopic plate 1 and is perpendicular to the telescopic direction of the telescopic plate 1; two end parts of each side of the scissor brace 3 are respectively and rotatably connected with the upper end and the lower end of the adjacent telescopic vertical rod 2, and a rotating shaft at the connection part is arranged in parallel to a rotating shaft between two inclined rods of the scissor brace 3; the effect of the cross braces 3 is the same as that of the cross braces on the scaffold, and the cross braces and the telescopic vertical rods 2 form a triangular structure, so that the overall rigidity of the supporting structure is increased, and the supporting structure is not easy to destabilize.

A pedal rod 4 is arranged between the two sets of scissor supports 3, the pedal rods 4 are arranged between the two parallel diagonal rods, are arranged at intervals along the length direction of the diagonal rods, and are fixedly connected with the diagonal rods at two ends; through setting up foot bar 4 formation ladder between the down tube at bridging 3, not only make full use of bridging 3, make it not only can regard as the reinforcement structure, can also regard as a part of ladder, the ladder that forms like this can be along with construction platform's altitude mixture control and change every single move angle in step, and the ladder is located bearing structure inside, and the workman receives bearing structure protection when the climbing, is difficult for falling.

The manhole 5 for workers to climb to the expansion plate 1 from the pedal rod 4 is arranged right above the pedal rod 4 at the uppermost end of the expansion plate 1, and a movable cover plate 51 is arranged on the manhole 5.

The base 21 is arranged under the telescopic vertical rod 2 in a cushioning mode, and the base 21 is fixedly connected with the telescopic vertical rod 2.

The outer side of the scissor support 3 is covered with a safety net.

Two diagonal rods of the scissor supports 3 are rotatably connected through the pedal rods 4, and two ends of the diagonal rod with the pedal rods 4 are rotatably connected with the telescopic vertical rod 2 through the pedal rods 4. Thus, the pedal lever 4 can be fully utilized, and the trouble of additionally arranging a pin shaft is eliminated.

The length of the telescopic joint of the telescopic plate 1 is not more than 0.5 m, so that the telescopic plate is convenient to fold, and if the telescopic joint is too long, the size is too large after folding, and the telescopic plate is inconvenient to use indoors.

Manhole 5 is the fillet rectangle, and the flexible direction setting of long limit perpendicular to expansion plate 1, removable cover 51 uses a minor face of manhole 5 to rotate with expansion plate 1 and is connected as the rotation axis. This facilitates the worker to drill the manhole 5 to the expansion plate 1 and to close the access panel 51, and if the access panel 51 is disposed on the long side of the manhole 5, it either prevents the worker from drilling the manhole 5 to the expansion plate 1 or the access panel 51 is too far from the worker to reach and close the access panel 51.

The four corners of the upper surface of the expansion plate 1 are provided with railing posts 11 for binding the rope fence, and the railing posts 11 are fixedly connected with the expansion plate 1.
