Detailed Description

The construction scaffold that this embodiment provided includes: a main body frame 1, a balancing weight 2 and an adjusting mechanism.

Referring to fig. 1 and 2, the main body frame 1 includes an operation platform 11 and a plurality of vertically arranged support shafts 13, the support shafts 13 are symmetrically distributed at four corners of the operation platform 11 and are fixedly connected with the operation platform 11, two adjacent support shafts 13 are connected through a horizontally arranged connecting shaft 14 to form a unified whole, travelling wheels 16 are mounted at the bottom of the support shafts 13, and the top ends of the support shafts 13 are higher than the operation platform 11 and are provided with transverse bars 9 between the adjacent support shafts 13 so that a fence is formed on the peripheral side of the operation platform 11.

The two opposite sides of the main body frame 1 are provided with the climbing ladders 12, which are convenient for people to go up and down.

A scissor brace 15 is further arranged between the two supporting shafts 13 on the same side to increase structural strength, and the side surface of the scissor brace 15 is opposite to the crawling ladder 12 so as not to influence the use of the crawling ladder 12.

The two ends of the balancing weight 2 are lapped on the connecting shaft 14 and are in sliding contact with the connecting shaft 14, and the balancing weight 2 can horizontally move in the area between the two ladders 12 under the drive of the adjusting mechanism.

The adjustment mechanism comprises a screw rod 3, a shaft rod 4, a first bevel gear 5, a second bevel gear 6, a first handle 7 and a second handle 8, wherein the screw rod 3 and the shaft rod 4 are all rotatably arranged on the main body frame 1, the screw rod 3 penetrates through the balancing weight 2 along the horizontal direction and is in threaded connection with the balancing weight 2, the first handle 7 is connected at one end of the screw rod 3, the shaft rod 4 is vertically arranged and extends to the lower part of the operation platform 11, the second handle 8 and the second bevel gear 6 are respectively arranged at two ends of the shaft rod 4, the second handle 8 is arranged at one end, close to the operation platform 11, of the shaft rod 4, and the first bevel gear 5 is arranged on the screw rod 3 and is meshed with the second bevel gear 6.

The rotation of the first handle 7 or the second handle 8 can drive the screw rod 3 to rotate, so that the balancing weight 2 slides on the connecting shaft 14 to balance the stress of the scaffold when a person climbs. In addition, the first handle 7 and the second handle 8 are designed to be one high and one low, so that workers can adjust the position of the balancing weight 2 on the ground or the working platform 11, and the safety requirements of the workers in the process of lifting and lowering the scaffold are met.

In order to facilitate the personnel to adjust the position of the balancing weight 2 on the operation platform 11, a window 100 penetrating through the end faces of the two sides of the top and the bottom of the operation platform 11 is reserved on the operation platform 11, the second handle 8 is close to the window 100, and the personnel can stretch the hand into the window to rotate the second handle 8.

For safety, a cover plate 200 for covering the window 100 is movably installed on the work platform 11, so that the surface of the work platform 11 is kept flat.

In this embodiment, when a worker needs to climb up the working platform 11, the first handle 7 is rotated first, so that the balancing weight 2 moves to the position of one of the ladders 12, then the working platform 11 is climbed up from the other ladder 12, the stress of the scaffold is balanced when the worker climbs up by using the balancing weight 2 in the process, after climbing up the working platform 11, the cover plate 200 can be opened, the hand stretches into the window 100 to rotate the second handle 8, so that the scaffold is more stable when the balancing weight 2 moves to the central position, and when the worker needs to climb down, the second handle 8 is rotated to move the balancing weight 2 to the position of one of the ladders 12, then the worker descends from the other ladder 12, and the whole process does not need other people to assist in stabilizing the scaffold, so that the safety of the scaffold is improved when the worker climbs down.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
