Description
Technical Field
The utility model relates to a wind power tower cylinder field specifically indicates to have an extensible stable form cat ladder.
Background
The wind power tower barrel is a tower pole of wind power generation, and mainly plays a supporting role in a wind generating set and absorbs the vibration of the set.
Tools such as a ladder stand need be used in the operation in a tower section of thick bamboo, and current cat ladder stability is not enough, and the stress point is too few, rocks always at the climbing in-process, makes the staff very worry.
The problem to foretell prior art existence designs an extensible stable form cat ladder is the utility model discloses the purpose of research.
SUMMERY OF THE UTILITY MODEL
To the problem that above-mentioned prior art exists, the utility model aims to provide an extensible stable form cat ladder can effectively solve the problem that above-mentioned prior art exists.
The technical scheme of the utility model is that:
an extensible stable ladder stand comprises a bottom ladder stand, a corresponding upper ladder stand is detachably sleeved above the bottom ladder stand, the bottom ladder stand and the upper ladder stand are respectively composed of two stand columns and a plurality of pedal plates, a plurality of bolt through holes are formed in the stand columns of the bottom ladder stand and the upper ladder stand at equal intervals, corresponding bolts are arranged between the bolt through holes of the bottom ladder stand and the upper ladder stand in a matched mode, two first elastic steel plates are arranged on one side of the bottom of the upper ladder stand, and the first elastic steel plates are arranged on the stand columns of the upper ladder stand; the bottom of the bottom ladder is hinged with a corresponding fixing plate, the top of the fixing plate is provided with a corresponding second elastic steel plate, and one end, which is not connected with the fixing plate, of the second elastic steel plate is arranged on the bottom ladder.
And corresponding gaskets are arranged at two ends of the first elastic steel plate.
The bottom of the fixed plate is covered with a corresponding latticed rubber layer.
The utility model has the advantages that:
the utility model discloses a set up first elastic steel plate, make it contact with the wall, increase the stress point of end cat ladder and last cat ladder junction, when the staff scrambleed the cat ladder, will produce the holding down force to the second elastic steel plate that sets up between fixed plate and the end cat ladder to increase the frictional force on fixed plate bottom rubber layer, thereby improved the stability in the cat ladder use. The utility model discloses simple structure, convenient to use can effectively improve the stability in the cat ladder use.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
To facilitate understanding of those skilled in the art, the structure of the present invention will now be described in further detail with reference to the following examples:
referring to fig. 1, an extensible stable ladder stand comprises a bottom ladder stand 1, a corresponding upper ladder stand 7 is detachably sleeved on the bottom ladder stand 1, the bottom ladder stand 1 and the upper ladder stand 7 are composed of two upright posts and a plurality of pedal plates, a plurality of bolt through holes are formed in the upright posts of the bottom ladder stand 1 and the upper ladder stand 7 at equal intervals, corresponding bolts are arranged between the bolt through holes of the bottom ladder stand 1 and the upper ladder stand 7 in a matching manner, two first elastic steel plates 5 are arranged on one side of the bottom of the upper ladder stand 7, and the first elastic steel plates 5 are arranged on the upright posts of the upper ladder stand 7; the bottom of the bottom ladder stand 1 is hinged with a corresponding fixing plate 3, the top of the fixing plate 3 is provided with a corresponding second elastic steel plate 2, and one end, which is not connected with the fixing plate 3, of the second elastic steel plate 2 is arranged on the bottom ladder stand 1.
And corresponding gaskets 6 are arranged at two ends of the first elastic steel plate 5.
The bottom of the fixed plate 3 is covered with a corresponding grid-shaped rubber layer 4.
The utility model discloses a set up first elastic steel plate 5, make it contact with the wall, increase the stress point of end cat ladder 1 and last cat ladder 7 junction, when the staff scrambleed the cat ladder, will produce the holding down force to second elastic steel plate 2 that sets up between fixed plate 3 and the end cat ladder 1 to increase the frictional force on 3 bottom rubber layers of fixed plate, thereby improved the stability in the cat ladder use.
The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made within the scope of the claims of the present invention should belong to the scope of the present invention.
Claims (3)
