Problems solved by technology

[0003] The early hanging baskets are similar to hanging ladders or buckets, and the working range is very limited. Later, anchor bolts are added to the bottom of the beam to install the hanging basket slideway, and then the hanging basket is installed. This kind of hanging basket is heavy and it is very troublesome to change the span, so it is not suitable for bridge inspection and maintenance construction with short operation time

Abstract

The invention discloses a light hanging basket applicable to bridge detection and maintenance operations. The light hanging basket is mainly formed by assembly of working platforms, sliding carts, rails, speed reducers and brake systems, and balance weights (20). The working platforms are connected with the sliding carts through hanging ropes (15). The speed reducers and brake systems are mounted on fixing platforms (12) of the sliding carts. The balance weights (20) are placed on balance weight platforms (19) of the sliding carts. The hanging basket is good in integrity and light in weight; each hanging rope is provided with an adjusting handle and one speed reducer, the hanging basket is convenient and stable to lift, and labor intensity of operators is reduced; the working platforms of the hanging basket can be assembled according to span based on the on-site conditions, the working platforms of the hanging basket are standardized components, the span of each platform is 4-6m, and flanges are welded at two ends of each platform to facilitate free extension of the platforms; the light hanging basket is applied to the field of bridge detection, bridge maintenance construction and the like.

Description

technical field [0001] The invention belongs to the field of bridge detection and maintenance construction, and in particular relates to a light hanging basket suitable for bridge detection and maintenance operations. For urban bridges where the sidewalks are wide or the traffic flow is too large to use the bridge inspection vehicle, this type of hanging basket is quick to install, has good controllability, high safety and low cost. Background technique [0002] Maintenance platforms are rarely installed in bridges in my country. This is mainly due to the high cost of bridge maintenance platforms, low frequency of use, and the need for regular maintenance. Currently, maintenance platforms are only installed on some special bridges. Therefore, in most bridge inspections and repairs, brackets or hangers, simple door frames or ladders, platforms on ships, hanging baskets for inspection and maintenance, and bridge inspection vehicles are usually used. At present, bridge inspect...
