Sealing platform device of lift shaft

Abstract

The invention discloses a sealing platform device of a lift shaft. The sealing platform device comprises a drive device, a base, a connecting rod set and a main span plate. The connecting rod set comprises a plurality of connecting rods, one end of the connecting rod set is connected with the main span plate in a pivoting mode, and the other end of the connecting rod set is connected with the base in a pivoting mode. The drive device drives the connecting rod set to rotate, and the main span plate can be rotated to be flush with the base. The main span plate is connected to the base through the connecting rod set in the pivoting mode to form a four-rod linkage mechanism. The size and the installation position of the connecting rod set are designed according to data of the main span plate so that the main span plate can be rotated to be flush with the base, the length of the main span plate can be designed to be slightly larger than the width of the lift shaft ( the two ends need to lean against the side wall of the lift shaft), the main span plate is shorter relative to main span plates in two kinds of structure platform devices in the background technology, the overall size of the sealing platform device can be made to be smaller, the occupied space is smaller, and requirements for constructing the platform in the lift shaft of a tower are met.

Description

Technical field [0001] The invention relates to an elevator shaft sealing platform device. Background technique [0002] When the elevator hoistway is maintained, it is necessary to temporarily set up a platform in the elevator hoistway that can place objects and allow people to work. The platform device for building this type of platform generally includes a base and a main span. The main span is movably installed on the base. On the seat, there are generally two common installation methods: one is that the main span is pivotally connected to the base; the other is that the main span is installed on the base through slide rails, and the main span can slide relative to the base. Out and close to achieve the effect of telescopic action. The platform devices of the above two structures can construct a platform for a general elevator hoistway. [0003] In some specific situations, such as tower elevators, the placement space around the elevator shaft is small, and the width of the e...

Problems solved by technology

[0003] In some specific cases, such as tower elevators, the space around the elevator shaft is small, and the width of the elevator shaft is greater than the height of the floor; the main span of the first type of platform device can only be equal to the height of the floor , so it cannot cover the elevator shaft, and cannot achieve the function of building a platform; in the second type of platform device, since a part of the main span board must be left on the base (if it is completely separated, it will not be able to be folded), the main span board The length is at least the width of the elevator shaft plus the length left in the base, so the length of the second platform device must be greater than the width of the elevator shaft, and the placement space around the elevator shaft of the tower generally cannot accommodate this type of second platform device. platform device
