Example 2:

the portal frame mainly comprises five parts: (1) A height-adjustable column and a width-adjustable beam; (2) The two rows of telescopic universal wheel combinations (3) can replace cross beams with various sizes and spans, and the cross beams with proper sizes can be flexibly selected and replaced according to the use environment. And (4) the device is detachable and assembled and is easy to transport. (5) weight, overload alarm can be displayed.

Multifunctional portal frame is formed:

(1) Width adjustable crossbeam: consists of two sections of I-shaped channel steel, a connecting box, two connecting sheets and two diagonal braces. One end of the diagonal brace is welded on the upper section of the portal frame upright post, and the other end of the diagonal brace is welded at the bottom of the connecting sheet; one end of the connecting piece is welded with the upper section of the portal frame upright post, one end of the channel steel is fastened with the connecting piece through a bolt connection through a pre-opening hole, the other end of the channel steel is fastened with a connecting box with a pre-opening hole through a bolt connection, and the channel steel can move in the connecting box in a telescopic mode. When the width of the portal frame to be adjusted is large, the large-span cross beam can be directly replaced;

(2) Height-adjustable's stand: the upright post is formed by an upper section and a lower section of rectangular channel steel with different sizes, the upper section is thinner, the lower section is thicker, the upper section of thinner channel steel is just attached to the inner wall of the lower section of channel steel and can move up and down (the height required by adjustment through up and down movement), the upper section and the lower section of upright post are fastened through the bolt connection of the pre-punched holes, the top end of the upper section of the upright post is welded with the connecting sheet, and the bottom end of the lower section of the upright post is fastened with the portal frame base through the connecting sheet in a bolt connection manner;

(3) Base that can span obstacles:

the base consists of two sections of rectangular channel steel, 8 telescopic universal wheels and 3 connecting pieces, wherein the channel steel is arranged on one section of each of the two sides of the base, 4 telescopic universal wheels are arranged on the two sides of each of the telescopic universal wheels, the universal wheels are fixedly welded at the bottom of the channel steel of the base, and the top of the channel steel of the base is welded with the three connecting pieces;

(4) Calabash capable of displaying weight and overload alarm:

the hoist comprises a lifting hook, an electronic scale with an alarm function and a lifting lug. The lifting lug is welded and fixed at the bottom of the connecting box of the cross beam, and the lower end of the lifting lug.

And (3) hanging an overload alarming electronic scale, hanging a hoist under the electronic scale, and finally hanging the hoist under the hoist.

The I-shaped channel steel (drilled with holes matched with the connecting plates) is connected and fastened with the connecting plates through bolts, and the I-shaped channel steel is connected and fastened with the connecting boxes through the holes drilled in advance through bolts, so that the portal frame cross beam is assembled with the upper sections of the upright posts; similarly, the gantry base is assembled and completed through the connection and fastening of the connecting plate, the diagonal braces and the base of the lower section of the upright post by bolts through pre-opened holes; finally, after the heights of the upper section and the lower section of the upright post are adjusted according to the requirement, the upper section and the lower section of the upright post are fastened through the pre-opened holes by using bolts, and the detachable portal frame is assembled in 3 steps.

Crossbeam width adjustable function:

the I-steel of the cross beam can freely stretch and retract in the connecting box, the adjustability of the width of the cross beam of the portal frame can be realized through the stretching length of the I-steel, and if the width of the portal frame needs to be greatly increased, the cross beam with larger span can be directly replaced.

Gantry height adjustable function:

the portal frame upright post is composed of two sections of rectangular channel steel with different sizes, the upper section of channel steel is small in size (just can move in the lower section of channel steel), and the portal frame height adjustability is achieved through the fact that the upper section of upright post moves up and down in the lower section of upright post.

Can span the functions of barriers such as uneven ground, threshold and the like:

the portal frame base comprises 8 telescopic universal wheels on two sides, 4 on each side. When the portal frame moves on a flat ground, the single side is commonly supported by four wheels. When encountering obstacles such as a threshold in the moving process, taking rightward movement as an example, firstly, the universal wheels shrink upwards to hang and pass the obstacles such as the threshold, at the moment, the weight is born by other three wheels, after the wheels pass the obstacles, the wheels are automatically put back on the ground, four wheels bear the weight together, and the principle that the other 3 wheels pass the obstacles is similar. Therefore, the portal frame has the function of crossing the threshold and the uneven ground, and the telescopic universal wheels with different sizes can be designed according to the size of the obstacle.
