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
The present invention relates to the used in nuclear power station polar crane, the synchronous device of particularly a kind of polar crane running trolley and installation dolly and car.
Background technology
Used in nuclear power station polar crane (hanging hereinafter to be referred as ring) is installed in the reactor building, and in the Nuclear Power Station stage, ring hangs the handling that is used to install the various heavy waress in the reactor building.In the nuclear station operation phase, ring hangs and is used for the required various handling services of maintenance of equipment in reactor cold-refueling and the reactor building.The safe reliability that ring hangs requires very high.Ring is hung in during the nuclear station installation, work compound behind running trolley and installation dolly and the car need be installed dolly and do not used separately; After installing, dolly is installed will be removed, and the run duration ring hangs only needs a running trolley just can satisfy operating needs.
As shown in Figure 1, the running trolley 1 of existing polar crane is provided with driver train 4, dolly 3 is installed is provided with driver train 5, behind joint operating device 2 and car, because two dollies have driver train separately respectively, therefore there are two problems that the dolly synchronous effect is not good.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of synchronous device of equipment of ring-shaped crane double trolley is provided, solved running trolley and the asynchronous problem that dolly and car are installed, and reduced by a cover operation driver train.
The present invention is achieved through the following technical solutions its goal of the invention.
A kind of synchronous device of equipment of ring-shaped crane double trolley comprises: contain the running trolley of driver train, dolly is installed, and connect running trolley and the joint operating device that dolly is installed, it is characterized in that: described installation dolly is not provided with driver train.
The present invention is hung in during the nuclear station installation according to ring, work compound after need and dolly and car being installed with running trolley, and hang the only actual condition of a running trolley of needs at the run duration ring, simultaneously, in order to solve the stationary problem of two dollies and car, the present invention only is provided with driver train on running trolley, and has cancelled the driver train that dolly is installed, and the corresponding power of motor that increases the operation driver train, running trolley drags the installation dolly by joint operating device.Like this, the asynchronous problem when thoroughly having solved two dollies and car, and reduced by a cover operation driver train, reduced cost of product.
Description of drawings
Fig. 1 is the structural representation of a kind of equipment of ring-shaped crane double trolley synchronous device of prior art;
Fig. 2 is the structural representation of a kind of equipment of ring-shaped crane double trolley synchronous device of the present invention.
The present invention is elaborated by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 2, a kind of synchronous device of equipment of ring-shaped crane double trolley by running trolley 1, is installed dolly 3, and connects running trolley 1 and joint operating device 2 compositions that dolly 3 is installed.Operation driver train 4 is set on the described running trolley 1, and described installation dolly 3 is not provided with driver train.Running trolley 1 drags by joint operating device 2 dolly 3 is installed, and has both thoroughly solved the stationary problem of two dollies, has reduced by a cover operation driver train again.
Claims (1)
1, a kind of synchronous device of equipment of ring-shaped crane double trolley, comprise: the running trolley (1), the installation dolly (3) that contain driver train (4), and connect running trolley (1) and the joint operating device (2) that dolly (3) is installed, it is characterized in that: on the described installation dolly (3) driver train is not set.
