Description
Technical Field
[0001] The utility model relates to the technical field of maintenance devices, in particular to a modular fire hydrant maintenance device. Background Art
[0002] Fire hydrants, formally called fire hydrants, are a type of fixed fire-fighting facility. Their main function is to control combustibles, isolate combustion-supporting materials, and eliminate ignition sources. They are divided into indoor fire hydrants and outdoor fire hydrants. Indoor fire hydrants are used by indoor pipe networks to supply water to the fire scene. They have valve interfaces and are indoor fixed fire-fighting facilities in factories, warehouses, high-rise buildings, public buildings, and ships. The use of fire hydrants requires regular inspection and maintenance to ensure that there will be no failures when they are needed. Therefore, a fire hydrant rapid inspection and maintenance device is needed. After searching, the prior art (publication number: CN220128697U) records "a fire hydrant rapid inspection and maintenance device. Aiming at the problem that the existing inspection and maintenance device is laborious to operate when fixing and removing the screws on the fire hydrant, and the fixing head needs to be replaced according to the size of the screw, which is inconvenient to use and greatly reduces the inspection efficiency, the following scheme is proposed, which includes a horizontal plate, two handles are symmetrically fixedly installed on the horizontal plate, a driving motor is fixedly installed at the bottom of the horizontal plate, a mounting column is fixedly installed on the output shaft of the driving motor, a fixing plate is fixedly installed at the bottom of the mounting column, a mounting plate is slidably installed on the fixing plate, a clamping device is slidably installed on the mounting plate, and two push plates are symmetrically fixedly installed at the bottom of the fixing plate. The utility model saves labor when fixing and removing the screws on the fire hydrant, and does not need to replace the fixing head according to the size of the screw. It is easy to use and greatly improves the inspection efficiency."
[0003] Although the fire hydrant quick inspection and maintenance device in the prior art is easy to use and greatly improves the inspection efficiency, it still has some shortcomings: the fixing block and the clamping plate involved in the existing fire hydrant quick inspection and maintenance device can only clamp the head of the bolt, and the fire hydrant is generally fixed by the combination of bolts and nuts. When it is only clamped on the head of the bolt, and there is a lack of a nut to keep the nut immobile at the bottom of the bolt, it is difficult to tighten the bolt, resulting in limitations in use. In addition, the clamping stability of the bolt head by a single clamping plate is deviated, which makes it easy to slip under a large torque. Utility Model Content

[0009] Furthermore, a second electric push rod is connected to the lower side of the first slide plate, and the bottom of the second electric push rod is fixed to the upper end of the connecting bottom plate.
[0010] Furthermore, the inner end of the vertical plate is connected to a horizontal guide plate, and a guide hole is opened inside the guide plate, and the rotating shaft rotates through the guide hole.
