in the drawings, the components represented by the respective reference numerals are listed below:
1. the auxiliary ladder comprises an auxiliary ladder main body, 2 connecting rods, 3 hanging rods, 4 bottom plates, 5 fixing plates, 6 cross arms, 7 protective railings, 8 cross tie beams, 9 support rail beams, 10 bridge piers.
Detailed Description
The present invention is further described in detail below with reference to specific embodiments so that those skilled in the art can more clearly understand the present invention.
As shown in fig. 1-2, an auxiliary ladder for installing a medium-low speed magnetic levitation contact rail arrester comprises an auxiliary ladder main body 1, wherein the top of the auxiliary ladder main body 1 is connected with a pair of connecting rods 2 horizontally arranged, hanging rods 3 are vertically installed downwards on the connecting rods 2, and a bottom plate 4 is arranged at the bottom of the auxiliary ladder main body 1.
In the above embodiment, the hanging rod 3 is inserted into the gap between the cross girders 8 at the top of the pier, so that the auxiliary ladder body 1 can be hung on the side of the cross girders 8, and the worker can stand on the bottom plate to perform the installation work of the contact rail arrester.
In order to improve the suspension stability of the auxiliary ladder main body 1, a fixing plate 5 is installed between the connecting rods, bolt through holes are formed in the fixing plate 5, and the fixing plate and the top of the transverse tie beam 8 are fixedly connected through the bolt through holes by bolts during suspension.
Preferably, the number of the bolt through holes is four, and the bolt through holes are arranged in a square shape, so that the auxiliary ladder can be prevented from overturning when the fixing plate 5 is fixed.
In order to improve the safety, the guard rail 7 is arranged on the outer side of the auxiliary ladder main body 1, so that the auxiliary ladder can be effectively prevented from falling to the outer side of the auxiliary ladder during operation.
In order to further improve the protection effect, the guard rails 7 are provided with three groups from top to bottom, and the three groups of guard rails 7 are connected with reinforcing steel bars, so that the protection area is increased, and the overall strength of the guard rails 7 is improved.
The guard rail 7 is arc-shaped, so that the human engineering is met, the protection performance is ensured, and the limitation of the guard rail 7 on the moving range of an operator is reduced.
One side of the bottom of the auxiliary ladder main body 1, which is close to the hanging rod 3, is provided with a steel pipe so as to be used for propping against the side surface of the transverse tie beam 8 and forming a reserved operation space so as to ensure the safety of construction.
