Quick locker for motor junction box

Abstract

The invention relates to a quick locker for a motor junction box, and the quick locker comprises a housing covering a junction box base, a locking device corresponding to a junction box screw hole isarranged at the bottom of the housing; the quick locker is fixed on the junction box under the action of the locking device; an elliptical rotary table is horizontally arranged in the housing; the elliptical rotary table is fixed in the housing through a fixing rod; the upper end of the fixing rod extends out of the housing and then is provided with a manual rotating wheel; the manual rotating wheel is connected with the elliptical rotary tables, the manual rotating wheel can rotate relative to the fixing rod, the elliptical rotary tables located at the two ends of the long shaft are connectedwith the locking device through the pull wires, the pull wires are pulled in and loosened by rotating the elliptical rotary tables in the forward direction or the reverse direction, and therefore thejunction box is locked and unlocked by the locking device. According to the invention, the junction box can be opened and closed quickly without any tool, so maintenance personnel can disassemble andconnect wires of the motor quickly, and daily maintenance work is facilitated.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a quick locker for a motor junction box. Background technique [0002] At present, the production rhythm of steel mills is fast, and the maintenance is often canceled or shortened due to the large output. In normal repairs, it is also race against time. In such a situation, the pressure is quite huge for the maintenance personnel, especially the roller table motor. When checking and opening the cover for the first time, due to the huge number, it takes a lot of time to twist the fixing screws on the junction box cover each time, which seriously affects the maintenance progress. [0003] The existing motor junction boxes are fixed with four screws, some are hexagonal, some are hexagonal, and some are cross-shaped. The tool wrench, hexagonal, and screwdriver needed may not be made into a uniform specification due to different requirements. , our maintenance personnel ha...

[0002] At present, the production rhythm of steel mills is fast, and the maintenance is often canceled or shortened due to the large output. In normal repairs, it is also race against time. In such a situation, the pressure is quite huge for the maintenance personnel, especially the roller table motor. When checking and opening the cover for the first time, due to the huge quantity, it takes a lot of time to unscrew the fixing screws on the cover of the junction box each time, which seriously affects the maintenance progress

[0003] The existing motor junction boxes are fixed with four screws, some are hexagonal, some are hexagonal, and some are cross-shaped. The tool wrench, hexagonal, and screwdriver needed may not be made into a uniform specification due to different requirements. , our maintenance personnel have to bring all kinds of tools to the site for disassembly and assembly, and due to the heavy water vapor, the screws are rusted, and the paint is not painted regularly, which leads to the inability to screw them out smoothly without some auxiliary means. When the motor needs to be opened for inspection, it takes a lot of time to open the cover, which seriously affects the maintenance progress and wastes manpower
