Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a safety fire hydrant maintenance device. Background Art

[0002] Fire hydrants are a type of fire rescue facility, mainly used to supply water to fire-fighting equipment. For example, fire hydrants installed on both sides of the road can replenish water for fire trucks and other equipment, and can assist rescue personnel in extinguishing fires. They are one of the important facilities in urban buildings.

[0003] Fire hydrants on both sides of the road are generally installed on the ground, which not only hinders the road surface, but is also susceptible to corrosion and damage after a long period of wind and sun exposure, which will affect the normal use of the fire hydrants. Some fire hydrants are set inside the ground, protected by a cover on the outside, and the movement of the fire hydrants is controlled by driving components such as electric motors inside. Circuit settings and control systems need to be installed during design. When in use, they are easily affected by internal environmental factors and cause short circuits, which will affect maintenance work and use, and are very inconvenient to use. For this reason, we propose a safe fire hydrant maintenance device. Utility Model Content

[0021] See also Figure 1-5 The utility model provides a technical solution: a safety fire hydrant maintenance device, including a fixing frame 1. When installing, a foundation pit is first dug on the ground. At this time, the fixing frame 1 is placed inside the foundation pit for fixing.

The fire hydrant body 4 can be connected to the outside through a hose. After the hose is connected, the fire hydrant body 1 can be controlled to move up and down, which is one of the common connection methods. The two groups of limit plates 2 can limit the movement of the mounting plate 3. Under the limitation of the limit plate 2, the mounting plate 3 can move vertically up and down to ensure the stability of the fire hydrant body 4 when moving.

[0023] A supporting mechanism 5 is installed below the mounting plate 3, and the mounting plate 3 can be pushed up and down by the supporting mechanism 5, and the fire hydrant body 4 can be controlled to move. The supporting mechanism 5 includes a fixing block 501, and the upper surface of the fixing block 501 is fixedly installed on the lower surface of the mounting plate 3. The internal rotation of the fixing block 501 is connected with a supporting rod 502, and the fixing block 501 can be pushed to move by the support of the supporting rod 502, which can further push the mounting plate 3 to move and drive the fire hydrant body 4 to move.

[0024] The outer surface of the support rod 502 is rotatably connected to a fixed block 2 503. Both the fixed block 1 501 and the fixed block 2 503 are provided with multiple groups and are symmetrically arranged. The horizontal movement of the fixed block 1 501 can drive one end of the support rod 502 to move. At this time, the support rod 502 can drive the fixed block 1 501 to move vertically. A cross bar 504 is fixedly installed on one side of the fixed block 2 503. The cross bar 504 can drive the fixed blocks 2 503 on both sides to move synchronously, thereby ensuring the stability of the fixed block 2 503 when moving.

[0025] A plurality of sets of fixing plates 505 are fixedly installed inside the fixing frame 1, and the fixing plates 505 are internally rotatably connected with threaded rods 506.

The rotating belt 9 is a chain belt structure. Both the fixed wheel 1 8 and the fixed wheel 2 10 are provided with multiple groups and are symmetrically arranged. The rotation of the fixed wheel 2 10 can drive the rotating belt 9 to rotate, and the rotation of the rotating belt 9 can drive the fixed wheel 1 8 to rotate and control the rotation of the worm 7. At this time, the rotation of the fixed wheel 2 10 above the fixed frame 1 can be further converted into the rotation of the worm wheel 6.

[0028] A blocking cover 11 is provided on the outside of the fixing frame 1, and the blocking cover 11 can be used to protect the top of the fire hydrant body 4 from being affected by external factors.

[0030] When not in use, the fire hydrant body 4 will be located at the lower position inside the fixed frame 1, and the fire hydrant body 4 can be protected from the outside by the baffle 11. When in use, the baffle 11 is rotated, and the baffle 11 can drive the connecting rod 12 to rotate, and the connecting rod 12 drives the fixed wheel 2 10 to rotate and drives the fixed wheel 1 8 to rotate through the rotating belt 9. At this time, the rotation of the fixed wheel 2 10 will be transmitted to the fixed wheel 1 8, and the fixed wheel 1 8 can drive the worm 7 to rotate, and the worm 7 can drive the meshing worm wheels 6 on both sides to rotate and drive the threaded rod 506 to rotate. When the threaded rod 506 rotates, it will control the fixed block 2 503 to move horizontally and linearly. When the fixed block moves, it can drive one end of the support rod 502 to move and prop up the fixed block 1 501 to move upward. At this time, the fire hydrant body 4 can be moved to the top of the fixed frame 1.
