Embodiment Construction

[0011] Such as figure 2 As shown, a synchronization device for double trolleys of a ring crane is composed of a running trolley 1, an installation trolley 3, and a paralleling device 2 connecting the running trolley 1 and the installation trolley 3. The operating trolley 1 is provided with a running driving mechanism 4, and the installation trolley 3 is not provided with a driving mechanism. The running trolley 1 is dragged and installed by the parallel device 2 to install the trolley 3, which not only completely solves the synchronization problem of the two trolleys, but also reduces a set of running driving mechanisms.

Abstract

The invention relates to synchronization equipment of a ring-shaped crane double trolley and relates to a ring-shaped crane used in a nuclear power station. The synchronization equipment comprises a travelling trolley containing a driving mechanism, an installation trolley, and a joint operating device connecting the traveling trolley and the installation trolley, and is characterized in that the installation trolley is not provided with the driving mechanism. As only the travelling trolley of the synchronization equipment is provided with the driving mechanism, the driving mechanism of the installation trolley is canceled, the motor power running the driving mechanism is correspondingly added, and the traveling trolley drags the installation trolley by the joint operating device. In this way, the desynchronized problem during the parallel operation of the two trolleys is completely solved, and a set of running driving mechanism is reduced, thus reducing the cost of the product.

Description

technical field [0001] The invention relates to a ring crane used in a nuclear power plant, in particular to a synchronizing device for paralleling the running trolley and the installation trolley of the ring crane. Background technique [0002] The ring crane for nuclear power plant (hereinafter referred to as the ring crane) is installed in the reactor building. During the construction stage of the nuclear power plant, the ring crane is used to lift various heavy equipment in the reactor building. During the operation phase of the nuclear power plant, ring cranes are used for various hoisting services required for reactor shutdown and refueling and equipment maintenance in the reactor building. The safety and reliability requirements of the ring crane are very high. During the installation of the nuclear power plant, the ring crane needs to combine the running trolley and the installation trolley to work together. The installation trolley is not used alone; after the inst...
