Detailed Description
The invention is further described below with reference to the following figures and examples:
the flexible steel structure climbing ladder is composed of a plurality of climbing ladder units 1 which are connected in series as shown in fig. 1, fig. 2, fig. 3 or fig. 4, each climbing ladder unit 1 comprises a cross rod 11 and supporting beams 12 respectively arranged at two ends of the cross rod 11, and each supporting beam 12 comprises a supporting part 121 arranged in the middle and connecting lugs 123 respectively arranged at two ends of the supporting part 121 along the length direction; the two ends of the cross bar 11 are respectively connected with the supporting parts 121 of the corresponding supporting beams 12; in two adjacent ascending stair units 1, two adjacent engaging lugs 123 are rotatably connected by a hinge structure.
Wherein the cross bar 11 is used as a ladder step for climbing by foot. One ascending ladder unit 1 is provided with a cross bar 11 and two support beams 12. The supporting beams 12 are used for supporting the cross bars 11 and connecting two adjacent ascending ladder units 1 in series. Be provided with engaging lug 123 respectively at the both ends of supporting part 121, engaging lug 123 not only regards as the connection structure that adjacent two ladder units 1 of ascending a height concatenated, simultaneously for ascending a height ladder unit 1 concatenates the back, surrounds formation climbing area by two adjacent horizontal poles 11 and the engaging lug 123 between two horizontal poles 11, for the staff climbing. The quantity of the climbing ladder units 1 is determined according to the diameter of the large-scale barrel 2 so as to smoothly climb to the top of the large-scale barrel 2 for operation.
During the specific use, as shown in figure 1 or figure 2, place parallels 7 on heat treatment platform truck 6, large-scale barrel 2 supports on parallels 7, concatenates each ascending ladder unit 1 in order and finishes, adopts the driving handling ascending ladder that concatenates and places it on the barrel 2 of crouching on heat treatment furnace platform truck 6, because of ascending ladder dead weight effect, the ascending ladder surrounds on barrel 2 and flagging naturally. After the ascending ladder is placed, the counterweight 3 is hung at the two ends of the ascending ladder through the connecting ropes 4. The staff alright climb along the ladder of ascending a height.
The flexible steel structure ascending ladder is formed by connecting a plurality of ascending ladder units 1 in series, two adjacent ascending ladder units 1 are rotatably connected through the hinge structure, namely, two adjacent ascending ladder units 1 can freely rotate around the hinge structure, so that the ascending ladder formed by connecting in series can be bent as required, and can be suitable for large-sized barrels 2 with different diameters; as shown in fig. 1 or fig. 2, after the ladder is hung on the large-sized cylinder 2, the ladder naturally droops under the action of self-weight, and the occupied area is small; and is convenient to store. Certainly, during the use, after the ladder of ascending a height was placed on large-scale barrel 2, need set up counter weight 3 at least one of them one end of ladder of ascending a height, when preventing that the operation personnel from climbing from the other end, the ladder of ascending a height takes place to slide, and counter weight 3 passes through connecting cable 4 and connects in the tip of ladder of ascending a height.
Since the ascending ladder surrounds the large cylinder 2 in use, that is, the ascending ladder is attached to the upper half circumference of the large cylinder 2, in order to provide sufficient stepping space between the cross bar 11 and the upper half circumference of the large cylinder 2 and facilitate climbing, it is preferable that, as shown in fig. 3, the support portion 121 includes a connection portion 1211 and a protrusion portion 1212, both ends of the connection portion 1211 are respectively connected with the corresponding connection lugs 123, and the protrusion portion 1212 protrudes toward the back surface in a direction perpendicular to the connection portion 1211 and the cross bar 11.
Wherein, the back is the back that flexible steel construction climbed the ladder, and flexible steel construction climbs the ladder and includes the back and openly, and the front is the one side of effect personnel climbing, and the back then is the one side adjacent with large-scale barrel 2. The provision of the projection 1212 has the following effects: the first bulge 1212 directly contacts the outer wall of the large-sized cylinder 2, so that the distance between the cross bar 11 and the outer wall of the large-sized cylinder 2 is increased, and climbing is facilitated; second, the supporting portion 121 is reinforced.
In order to adapt to the shape of the large cylinder 2 and reduce wear, it is preferable that the convex portion 1212 has an arc shape.
For convenience of manufacture, the engaging lug 123 and the connecting portion 1211 are preferably shaped like a common arc.
The protrusion 1212 is shaped like an arc concentric with the connecting lug 123 or the connecting portion 1211.
The sizes of the ascending ladder units 1 can be the same, but when two adjacent ascending ladder units 1 are hinged, the central lines of the two ascending ladder units 1 cannot be centered, so that the installation is inconvenient, and in order to avoid the problem, preferably, the ascending ladder units 1 are divided into a first ascending ladder unit 1A and a second ascending ladder unit 1B, and the first ascending ladder unit 1A and the second ascending ladder unit 1B are distributed at intervals along the length direction of the ascending ladder; the support beam 12 of the first ascending stair unit 1A is positioned between two support beams of the second adjacent ascending stair unit 1B.
The structural shapes of the first ascending ladder unit 1A and the second ascending ladder unit 1B are completely the same, only the width sizes of the first ascending ladder unit 1A and the second ascending ladder unit 1B are different, wherein the inner side widths D2 of the two opposite connecting lugs 123 of the second ascending ladder unit 1B are slightly larger than the outer side widths D1 of the two opposite connecting lugs 123 of the first ascending ladder unit 1A, so that the first ascending ladder unit 1A and the second ascending ladder unit 1B can freely rotate around the hinge structure to realize the flexible function.
In order to facilitate the change of the length of the ladder as required, it is preferable that the hinge structure is a bolt assembly 5. The detachable connection of the ascending ladder unit 1 is realized through the bolt assembly 5 consisting of the bolts, the nuts and the washers, and the length of the ascending ladder can be adjusted by increasing or decreasing the number of the ascending ladder units 1.
