Description

Quasi-closed sliding conductor fixing and protecting device

Technical Field

The utility model relates to a steel frame construction specifically is a fixed, bear and safety protection mechanical device of gantry crane ground mounted sliding conductor.

Background

The power supply mode of the outdoor portal crane is divided into a reel cable type and a sliding conductor type, but the reel cable type power supply mode is poor in effect when being actually seen from the site, and most of the reel cable type power supply mode is supplied with power by the sliding conductor type. The outdoor portal crane sliding wire installation mode can adopt two modes: one is a tower pole overhead type and is mainly used for a portal crane track with a wide environment at one side and no obstacles or inflammable and explosive places; the other type is a ground type, and the installation mode is adopted under the influence of factors such as terrain environment and the like. The ground installation of the sliding wire is suitable for special occasions, but the height is lower compared with the overhead installation of a tower pole, the sliding wire is easy to be touched by external force, personnel and the like, and the safety protection performance is poor. Therefore, the sliding conductor must be effectively fixed and protected to ensure the power supply safety of the sliding contact line of the gantry crane.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: the utility model provides a protection device is fixed to quasi-closed slide conductor for fixed, bear gantry crane power supply slide conductor, possess slide conductor safety protection function simultaneously, avoid personnel's contact or receive external force, environment (sleet, raise dust etc.) destruction influence, improve the fail safe nature and the closure of slide conductor power supply.

Realize the utility model discloses the technical scheme that the purpose was taken is: the device comprises upright posts, an upper support, an upper guard plate, a rear guard plate, unit type movable side guard plates, upright post fixed connecting frames and a sliding lead bearing frame, wherein each upright post is uniformly spaced, one end of each upright post is embedded into a concrete base on the bottom surface of a foundation, one end of each upper support is horizontally fixed at the top of each upright post, all upright posts are fixedly connected in series by the upright post fixed connecting frames, a unit is arranged between every two upright posts, and one end of the sliding lead bearing frame is respectively and vertically fixed at the middle part of each upright post; the upper guard plate is fixed on the upper bracket, and the rear guard plate is fixedly arranged behind the two upright posts; a shaft sleeve is fixedly arranged at the edge of the front end of the upper guard plate, and the unit type movable side guard plate is connected on the shaft sleeve through a pin shaft.

The utility model has the advantages that: the structure is simple, the manufacture and the processing are easy, the welding process is adopted, the structure is firm and durable, and the cost is low; directly burying the device upright post below a ground foundation on one side of the track, pouring concrete for fixing, and determining the digging depth according to the actual situation; the slide wire group can be adjusted left and right through the oblong hole; the unit type movable side guard plate, the upper guard plate and the rear guard plate basically form a quasi-closed space, the internal sliding wire is guaranteed to be prevented from being affected externally, the unit type movable side guard plate and the upper guard plate are connected through the pin shaft and the shaft sleeve, the up-and-down movable turnover of the unit type movable side guard plate can be achieved, and the sliding wire is convenient to inspect and overhaul daily. The technical scheme is suitable for the environment of flammable and explosive or special geographical positions, effectively solves the problems of the defects of the reel cable and the prior art, and has higher practical economic value.
