Description
Technical Field
The utility model relates to the technical field of bridge crane overhauling and maintaining devices, in particular to a bridge crane filter replacing device.
Background
The variable frequency crane has the advantages that the speed regulation range of variable frequency speed regulation (the speed of the motor is changed by changing the power supply frequency of the motor) is wide, the smoothness is high, the external voltage of the stator is changed simultaneously during variable frequency, the constant power or constant torque speed regulation can be realized to meet the requirements of different loads, the static difference rate of the characteristic at low speed is high, the speed regulation efficiency and the power factor are high, and the variable frequency crane is one of the most promising asynchronous motor speed regulation methods.
330T is the most advanced full frequency conversion crane in China, adopts the working principle of AC-DC-AC, and the filter is one part of a power distribution system and is one of the most important spare parts, and the crane cannot work after being damaged, so the filter needs to be overhauled and replaced regularly and needs to be replaced quickly. However, the filter has a dead weight of 500 kg, generally, an electric room is narrow in space and free of lifting points, the filter can be lifted by manpower only, the filter can be lifted up and down by manpower, more than 4 hours are needed for each replacement, any 330T crane is stopped for 4 hours, factory-level or even company-level accidents can be caused, and safety accidents such as crushing, smashing and the like are easy to occur.
Disclosure of Invention

In order to achieve the purpose, the utility model adopts the following technical scheme:
a bridge crane filter replacing device comprises a platform, a supporting base, a guide rail and a cross beam; the platform is of a rectangular plate structure, and the supporting base is fixedly connected to the lower surface of the platform; the two guide rails are parallel to each other, one end of each guide rail is fixedly connected to one end of the upper surface of the platform, and the other end of each guide rail is fixedly connected to two ends of the cross beam.
One ends of the two guide rails are fixedly connected to one end of the upper surface of the platform in a detachable mode through bolts, and the other ends of the two guide rails are fixedly connected to two ends of the cross beam in a detachable mode through bolts.
The support base is of a lifting structure and comprises an upper support base and a lower support base, the upper support base is fixedly connected to the lower surface of the platform, and the upper support base is connected with the lower support base through a strip hole and a bolt.
Still include the fixing base, the fixing base is the ohm type, and the middle part is equipped with bellied fixed slot, and both sides are equipped with the installation ear, and the crossbeam is placed in the fixed slot, and the crossbeam passes through the fixing base to be fixed subaerial.
The width of the guide rail corresponds to the bottom wheel of the bridge crane filter.
Compared with the prior art, the utility model has the beneficial effects that:
1) the filter repairing and replacing device is provided with the platform and the guide rail, when the filter is repaired and replaced by the crane, the filter to be repaired and replaced is pushed to the ground along the platform and the guide rail without being lifted up and down manually, and the repaired filter or a new filter is pushed to the original position along the guide rail and the platform, so that the repair and replacement of the filter are completed. The utility model shortens the overhaul and rush-repair time of replacing the filter of the crane, reduces the labor intensity of the operating personnel, ensures the personal safety of the operating personnel and ensures the stable and smooth production.
2) One ends of the two guide rails are detachably and fixedly connected with one end of the upper surface of the platform through bolts, and the other ends of the two guide rails are detachably and fixedly connected with two ends of the cross beam through bolts; the utility model adopts a detachable mode for assembly, adapts to narrow working environment and is convenient for installation and disassembly.
3) The supporting base is of a lifting structure, the height of the platform is adjustable, and the adaptability is strong.

Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings:
example (b):
as shown in fig. 1-4, a bridge crane filter replacing device comprises a platform 1, a supporting base 2, a guide rail 3, a cross beam 4 and a fixed seat 5.
The platform 1 is of a rectangular plate structure, the length of the platform 1 is 1200mm, the width of the platform 1 is 1000mm, and the thickness of the platform is more than 10 mm.
Support base 2 includes support base 21 and under bracing base 22, goes up support base 21 and under bracing base 22 and all adopts the angle steel preparation, goes up support base 21 rigid coupling at 1 lower surface of platform, goes up support base 21 side and is equipped with rectangular hole, goes up support base 21 and under bracing base 22 and passes through rectangular hole and bolted connection, supports base 2 and is elevation structure, platform 1's height-adjustable, strong adaptability.
