In this embodiment, a rotary steel ladder bed is disclosed, and fig. 1 shows a three-dimensional structure of the rotary steel ladder bed, and also shows a state of the rotary steel ladder after the assembly thereof is completed. Because the rotary steel ladder is arranged around the chimney, the rotary steel ladder can be divided into a plurality of sections when being processed and manufactured, and then the rotary steel ladder is assembled on the chimney. The rotary steel ladder jig frame in the embodiment is used for assembling and welding the ladder beams and the pedals of the single-section rotary steel ladder.

Referring to fig. 1, the rotating steel ladder bed in this embodiment includes a support floor, an inner column 3, an outer column 4, a connecting rod 5, and a support rod 6. The supporting bottom plate comprises six laths 1 and a reinforcing plate 2, wherein the six laths 1 are distributed in a fan shape, and the reinforcing plate 2 is fixedly connected to one side of each lath 1, so that the six laths 1 and the reinforcing plate 2 form a fixed integral structure. In this embodiment, the lath 1 and the reinforcing plate 2 are both channel steels, wherein the openings of the channel steels constituting the lath 1 are directed downward and the openings of the channel steels constituting the reinforcing plate 2 are directed upward. Because the channel steel is the material commonly used in steel construction processing factories, the spare part and the waste material can be utilized when the jig frame is manufactured, and the cost can be saved. In addition, the arrangement of the opening direction of the channel steel can increase the contact area between the reinforcing plate 2 and the slat 1, thereby improving the stability of the whole supporting bottom plate. The fan-shaped distributed laths 1 can more stably support the upright posts and the steel ladder.

The inner side upright posts 3 and the outer side upright posts 4 are respectively provided with five parts which are respectively positioned at the inner side and the outer side of the slat 1, are distributed in an arc shape, and form an arc-shaped space capable of accommodating a steel ladder between the inner side upright posts and the outer side upright posts. In this embodiment, the inner upright 3 and the outer upright 4 are steel pipes, and the lower ends thereof are welded to the lath 1 and perpendicular to the surface of the lath 1, so that a stable and firm vertical supporting structure can be formed. The two ends of the connecting rod 5 are fixedly connected to the adjacent inner side upright posts 3 and the adjacent outer side upright posts 4, three connecting rods 5 are arranged between the two adjacent upright posts on the same side from top to bottom, and the stability of the upright posts can be further improved. The two ends of the supporting rod 6 are respectively fixedly connected to the inner upright post 3 and the outer upright post 4 which are positioned on the same slat 1 and are used for supporting the rotary steel ladder. In this embodiment, the support bars 6 are provided with five in total, the height of which increases from one side of the support base plate to the other side, and the gradient is the same as that of the rotating steel ladder.

This rotatory steel ladder bed-jig can form the space of holding rotatory steel ladder between stand and bracing piece 6 to bracing piece 6 arranges according to the ascending direction of ladder beam 7, places ladder beam 7 on bracing piece 6 and after the spot welding is fixed, can assemble between two ladder beams 7, welds footboard 8. Namely, the rotating steel ladder jig frame can be used for rapidly positioning and fixing the ladder beam 7, so that the pedal 8 can be accurately welded on the ladder beam 7.

In other embodiments, the number of the laths 1, the upright posts, the connecting rods 5 and the supporting rods 6 can be adjusted in real time according to the length of the single-section rotary steel ladder, and when the length of the single-section rotary steel ladder is increased, the number of the laths 1, the upright posts and the supporting rods 6 can be correspondingly increased so as to form stable support for the rotary steel ladder. Wherein the number of the strips 1 is not less than three when adjusting. The number of connecting rods 5 between two adjacent uprights should not be smaller than two.

In this embodiment, the distance between the inner upright 3 and the outer upright 4 on the same slat 1 is equal to the width of the rotating steel ladder. Therefore, when assembling the rotary steel ladder, two ladder beams 7 are respectively abutted against the inner side upright posts 3 and the outer side upright posts 4, the positioning of the ladder beams 7 can be completed, and then the pedals 8 can be assembled and welded between the ladder beams 7, so that the processing efficiency of the rotary steel ladder is further improved.

In this embodiment, stand, connecting rod 5, bracing piece 6 are the steel pipe, and link together through the steel pipe buckle each other, can install this bed-jig fast to after rotatory steel ladder processing finishes, can also dismantle, realize reuse, further saved the processing cost.

In this embodiment, the connecting rod 5 is provided on the side of the inner column 3 and the outer column 4 away from the rotating steel ladder, so that the connecting rod 5 will not interfere when the ladder beam 7 is provided between the columns, and the processing efficiency can be improved to some extent.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
