And when each bridge crane operates independently, the wireless network bridge is in a disconnected state. When'parallel operation 'operation is needed, only a'parallel operation' switch on the parallel operation console S11 needs to be turned on, and the control system PLC performs data exchange through the Ethernet. Therefore, parallel operation connection is achieved, parallel operation communication of two vehicles is achieved, conversion of the bridge crane of the large hydropower station between a single-vehicle operation working condition and a double-vehicle parallel operation working condition can be conveniently and rapidly achieved, and practicability is improved.

Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of hydroelectric station bridge crane technology, especially relate to a convenient to use's hydroelectric station bridge crane wireless parallel car connection system. BACKGROUND

[0002] Large hydroelectric station installation room often installs two and above large tonnage bridge cranes, usually, each bridge crane is operated independently, and is used for daily tonnage lower hoisting task. When the generator set rotor or runner of high tonnage needs to be hoisted, two large tonnage bridge cranes need to be operated in parallel and synchronously, so that the rotor or runner of more than one ton is lifted.

[0003] At present, the Chinese utility model with the announcement number CN208071134U discloses a parallel car device between hydroelectric station bridge cranes. However, the current parallel connection between two bridge cranes generally adopts a wired mode, and aviation plugs or other various bus plugs are mostly connected. Although the parallel control function can be realized, there are some disadvantages in the actual use process. For example, the connection is complicated, the operating personnel need to cross the cable in the air, and the operating personnel have a certain risk of falling from a high altitude. And because the connecting cable is in the disconnected state usually, if the connection interface or the connecting cable is not maintained in place and the connecting cable is lost or damaged, the cable connection will be unreliable, and the connection will be unstable or even fail during use. In addition, the vibration, speed change and other adverse factors during the operation of the crane will further aggravate the unstable connection. UTILITY MODEL CONTENTS

[0013] The utility model discloses further set up: the inside of main bridge crane still be equipped with parallel operation operation platform S11, parallel operation operation platform S11 with PLC integrated ethernet interface A11 electricity is connected.

[0014] Example 1:

[0015] Reference Figure 1The utility model provides a convenient water and electricity station bridge crane wireless parallel connection system, including main bridge crane and vice bridge crane, the inside of main bridge crane is installed with industrial computer NB1, industrial switch U10, PLC integrated ethernet interface A11 respectively, the inside of vice bridge crane is installed with industrial computer NB2, industrial switch U20, PLC integrated ethernet interface A21 respectively, and industrial wireless bridge U11 and industrial wireless bridge U21 that still cooperates and uses each other between main bridge crane and vice bridge crane is installed. When each bridge crane is independently operated, the wireless bridge is in the disconnected state. When the operation of the main bridge crane and the vice bridge crane is required, only the "parallel operation" switch on the parallel operation console S11 is turned on, and the control system PLC exchanges data through the Ethernet. Thus, the parallel connection is realized, the communication of the two cranes is realized, the conversion between the single-machine operation condition and the double-machine parallel operation condition of the large-scale water and electricity station bridge crane is conveniently and quickly realized, and the practicability is improved.

[0016] Reference Figure 1 The inside of the main bridge crane is also provided with the parallel operation console S11, and the parallel operation console S11 is electrically connected with the PLC integrated Ethernet interface A11.
