Moving platform for mounting inner-layer plate of steel structure factory building roof

Technical Field

The utility model relates to a factory building construction technical field specifically says a moving platform of steel construction factory building roof inner plating installation usefulness.

Background

The steel structure factory building generally includes the steel column of steel construction and the steel roof truss of steel construction, has preset on the steel column of a plurality of steel constructions and link up steel construction factory building length direction's driving beam or called overhead traveling crane roof beam or called crane roof beam, and some driving tracks that have the I-steel that has link up steel construction factory building length direction of presetting on the driving roof beam are the I-steel track promptly.

For the needs of indoor beauty, sanitation and the like, an inner plate such as a color inner plate is arranged in the roof of the steel structure and serves as a decorative plate, the inner plate is a reverse buckle plate, and the inner plate is fixed on a purline of the roof of the steel structure from bottom to top by self-tapping screws during installation. The traditional construction method is to set up a full scaffold, and the construction cost is high and the construction period is long.

In recent years, a mobile platform using a travelling crane beam and an I-shaped steel rail generally comprises a steel truss crossing two travelling crane beams, a plurality of rollers used for rolling on the I-shaped steel rail are respectively arranged at the bottoms of two ends of the steel truss, a working platform with pedals is arranged at the top of the steel truss, and protective railings are arranged on two sides of the working platform.

However, the mobile platform for installing the inner plate of the steel structure factory building roof in the prior art still has the following defects: 1. for the sake of safety, a limiting block for preventing the roller from deviating is generally arranged on at least one side of the roller, but interference and resistance increase are easily caused objectively, so that the rolling flexibility of the roller is influenced, and further the moving flexibility and reliability of the mobile platform are influenced. 2. The moving traction device of the moving platform is generally a chain block, namely a chain block, and is relatively laborious in actual operation, and the two persons exerting force on the two ends of the moving platform are difficult to control balance; the phenomenon of shell blocking is easy to occur in the actual operation of the horizontal pulling chain block; the length of the zipper is 12 meters at the longest, and in actual operation, a chain block needs to be mounted on the steel upright in front of the operation platform for many times, so that time and labor are wasted; in addition, the mobile platform is generally several meters high, but the chain block is only one point in height, and when the chain block drives the mobile platform to move forward, the force point is unreasonable, labor-saving and unreliable. 3. In the construction process, the construction platform is positioned by self gravity, and the potential safety hazard of sliding exists.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a moving platform of steel construction factory building roof inner plate installation usefulness that gyro wheel roll is nimble, anti-rolling wheel walks inclined to one side limit structure can not produce interference and resistance to the gyro wheel.

The technical scheme of the utility model is that a mobile platform for installing the inner plate of the steel structure factory building roof is provided, which comprises a traction device and a steel truss, the bottom of each of the two ends of the steel truss is provided with a plurality of rollers for rolling on respective tracks, the top of the steel truss is provided with a working platform with a pedal, the two sides of the working platform are provided with protective railings, and each roller is composed of a pair of first rolling bearings arranged in parallel; the structure for preventing the roller from deviating is a rolling structure, or: a groove type track formed by the channel steel with the upward opening also serves as a structure for preventing the roller from deviating, and a gap is reserved between the first rolling bearing and the two side plates of the channel steel.

After the structure more than adopting, the utility model discloses moving platform of steel construction factory building roof inner plating installation usefulness has following advantage: each roller is composed of a pair of first rolling bearings arranged in parallel, the rolling of the rolling bearings is flexible, the structure for preventing the roller from deviating is a rolling structure, or a groove type track composed of channel steel with an upward opening is also used as the structure for preventing the roller from deviating, and a gap is reserved between the first rolling bearings and two side plates of the channel steel. Therefore, the safety of preventing the roller from deviating, namely preventing the moving platform from derailing is effectively guaranteed, meanwhile, the structure for preventing the roller from deviating cannot interfere with the roller, resistance cannot be generated, the roller rolls flexibly and reliably, and the moving platform moves flexibly and reliably.

Furthermore, each bearing support frame at the bottom of the two ends of the steel truss is provided with at least one second rolling bearing which is in rolling fit with the side wall of the top plate of the I-shaped steel track preset on the travelling beam. After the structure for preventing the roller from deviating adopts the specific structure, a plurality of second rolling bearings for preventing the roller from deviating are arranged at the two ends of the steel truss and are in rolling fit with the side wall of the top plate of the I-shaped steel track, the possibility that the steel truss moves towards the left end and the right end is strictly limited, the safety of preventing the roller from deviating, namely the derailment of the mobile platform is more powerfully guaranteed, meanwhile, the second rolling bearings for preventing the roller from deviating do not interfere with the roller due to the rolling fit with the guide rail, and the resistance is not generated, the rolling of the roller is flexible and reliable, and the mobile platform is flexible and reliable to move.
