At present, the fire-fighting height of high-pressure fire-fighting vehicles is about 100 meters, which cannot meet the use requirements of higher floors. For buildings with a height exceeding 100 meters, the fire-fighting method still relies on firefighters climbing the stairs on foot. Relying on firefighters is inefficient, and the fire-fighting environment is very dangerous and the fire-fighting difficulty is great. Or equipping fire-fighting vehicles with unmanned aerial vehicle systems has a high use cost and cannot be popularized on a large scale. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is: In order to solve the problem that the current fire-fighting height of high-pressure fire-fighting vehicles is about 100 meters, which cannot meet the use requirements of higher floors. For buildings with a height exceeding 100 meters, the fire-fighting method still relies on firefighters climbing the stairs on foot. Relying on firefighters is inefficient, and the fire-fighting environment is very dangerous and the fire-fighting difficulty is great. Or equipping fire-fighting vehicles with unmanned aerial vehicle systems has a high use cost and cannot be popularized on a large scale. Now a lifting fire-fighting mechanism is provided.

[0004] The technical solution adopted by the utility model to solve its technical problems is: A lifting fire-fighting mechanism includes a guiding component, a transmission component and a fire-fighting platform for loading fire-fighting appliances. The guiding component is fixedly installed on the outer wall of the building. The fire-fighting platform is arranged on the guiding component and is used to guide the fire-fighting platform during displacement. The transmission component is arranged on the fire-fighting platform and is used to be in transmission connection with a power source. Compared with the prior art, in this solution, the power source drives the fire-fighting platform to displace on the guiding component on the outer wall of the building through the transmission component, quickly raises the fire-fighting platform to the required floor height and conducts fire-fighting operations, meets the use requirements, does not require personnel to climb on foot, greatly reduces the risk of fire-fighting operations, has a lower cost, and is suitable for large-scale popularization and use.

[0005] In order to realize the guiding of the guiding component to the fire-fighting platform, in some preferred embodiments, the guiding component includes a fixed support plate and a guide rail groove installed on the fixed support plate. The fixed support plate is fixedly installed on the outer wall of the building. A guide wheel set matching the guide rail groove is arranged on the fire-fighting platform, and the guide wheel set is arranged on the guide rail groove. Through the cooperation of the guide wheel set on the fire-fighting platform and the guide rail groove on the fixed support plate, the fire-fighting platform is restricted to displace in the direction of the guide rail groove, ensuring the stable and reliable displacement of the fire-fighting platform.

[0006] To ensure that the fire fighting platform can displace along the direction of the guide rail groove, in some preferred embodiments, the guide wheel set includes a first guide wheel set for restricting the axial displacement of the fire fighting platform in the guide rail groove. By restricting the axial displacement of the fire fighting platform through the first guide wheel set, it is ensured that the fire fighting platform can displace stably and reliably along the direction of the guide rail groove.

[0007] To implement the first guide wheel set, in some preferred embodiments, the first guide wheel set includes at least two relatively arranged first guide wheels. There are two guide rail grooves which are relatively arranged on the fixed support plate, and the relatively arranged first guide wheels are respectively arranged to roll in the two guide rail grooves. The two opposite guide rail grooves cooperate with the relatively arranged first guide wheels to restrict the axial displacement of the fire fighting platform in the guide rail groove.

[0008] To prevent the fire fighting platform from swaying left and right during axial displacement in the guide rail groove, in some preferred embodiments, the guide wheel set further includes a second guide wheel set for preventing the fire fighting platform from swaying during axial displacement in the guide rail groove. By arranging the second guide wheel set on the fire fighting platform, the second guide wheel set is used to prevent the fire fighting platform from swaying during axial displacement in the guide rail groove, ensuring the stable and reliable displacement of the fire fighting platform.

[0009] To implement the second guide wheel set, in some preferred embodiments, the second guide wheel set includes second guide wheels arranged corresponding to the first guide wheels. The second guide wheels are abutted against the outside of the guide rail groove, the guide rail groove is located between the first guide wheels and the second guide wheels, and the axial direction of the rotation center of the first guide wheels intersects with the axial direction of the rotation center of the second guide wheels. By abutting the second guide wheels against the outside of the guide rail groove, arranging the guide rail groove between the first guide wheels and the second guide wheels, and making the rolling center axes of the first guide wheels and the second guide wheels intersect, when the fire fighting platform displaces, the corresponding second guide wheels on both sides prevent the fire fighting platform from swaying during axial displacement in the guide rail groove.

[0010] To implement the transmission component, in some preferred embodiments, the transmission component includes a lifting rack and a gear meshing with it. The lifting rack is fixedly installed on the fixed support plate along the displacement direction of the fire fighting platform. The transmission connection between the fire fighting platform and the power source is realized through the meshing of the lifting rack and the gear.

[0011] To implement the power source, in some preferred embodiments, the power source is a motor, the motor is installed on the fire fighting platform, and the gear is arranged on the output end of the motor.

[0012] To implement the transmission component, in some preferred embodiments, the transmission component includes a rope, and one end of the rope is arranged on the fire fighting platform. The transmission connection between the fire fighting platform and the power source is realized through the rope.

[0013] To implement the power source, in some preferred embodiments, the power source is a winch, and the other end of the rope is arranged on the winch.

[0014] The beneficial effects of the present utility model are as follows: When the lifting fire-fighting mechanism of the present utility model is in use, the power source drives the fire-fighting platform to displace on the guiding component on the outer wall of the building through the transmission component, and quickly raises the fire-fighting platform to the required floor height for fire extinguishing operations, meeting the usage requirements. There is no need for personnel to climb on foot, greatly reducing the risk of fire-fighting operations, with lower costs, suitable for large-scale popularization. It avoids the problem that the current high-pressure fire-fighting vehicles can only reach a height of about 100M for fire extinguishing, unable to meet the usage requirements of higher floors. For buildings over 100M in height, the fire-fighting method still relies on firefighters climbing the building on foot, with low efficiency, a very dangerous fire-fighting environment and great difficulty, or equipping fire-fighting vehicles with unmanned aerial vehicle systems, which has high usage costs and cannot be popularized on a large scale.

[0030] Embodiment 1

[0031] As Figures 1-5 shown, a lifting fire-fighting mechanism includes a guiding assembly 1, a transmission assembly 2, and a fire-fighting platform 3. Fire-fighting appliances, such as fire sprinklers, are loaded on the fire-fighting platform 3. The fixed support plate 101 of the guiding assembly 1 is fixedly installed on the exterior wall of the building. The guiding assembly 1 is arranged along the height direction of the exterior wall of the building. The fire-fighting platform 3 is arranged on the guiding assembly 1. The guiding assembly 1 is used to guide the fire-fighting platform 3 during displacement. The transmission assembly 2 is arranged on the fire-fighting platform 3. The transmission assembly 2 is used to be in transmission connection with a power source 4, so as to realize that the power source 4 drives the fire-fighting platform 3 to displace on the guiding assembly 1 on the exterior wall of the building through the transmission assembly 2.

[0032] The guiding component 1 includes a fixed support plate 101 and two guide rail grooves 102. The two guide rail grooves 102 are installed on the fixed support plate 101. The openings of the two guide rail grooves 102 are arranged oppositely towards the left and right sides respectively. In this embodiment, the opening of the left guide rail groove 102 faces left, and the opening of the right guide rail groove 102 faces right. The fixed support plate 101 is fixedly installed on the exterior wall of the building by bolts. A guide wheel set matching the guide rail grooves 102 is arranged on the fire platform 3. The lifting component is arranged on the guide rail grooves 102, so that the guiding component 1 is fixedly installed on the exterior wall of the building along the height direction of the exterior wall of the building.

[0033] The guide wheel set includes a first guide wheel set and a second guide wheel set. The first guide wheel set includes at least two relatively arranged first guide wheels 301. There are two guide rail grooves 102 and they are relatively arranged on both sides of the fixed support plate 101. The relatively arranged first guide wheels 301 are respectively arranged to roll in the two guide rail grooves 102, so that the first guide wheel 301 group is used to limit the axial displacement of the fire platform 3 in the guide rail grooves 102. The second guide wheel set includes second guide wheels 302 arranged corresponding to the first guide wheels 301. The second guide wheels 302 are abutted against the outside of the guide rail grooves 102. The guide rail grooves 102 are located between the first guide wheels 301 and the second guide wheels 302. The axial direction of the rotation center of the first guide wheels 301 and the axial direction of the rotation center of the second guide wheels 302 are arranged to intersect with each other, and at the same time, the axial direction of the rotation center of the first guide wheels 301 and the axial direction of the rotation center of the second guide wheels 302 are arranged to stagger with each other. In this embodiment, the axial lines of the rotation centers of the first guide wheels 301 and the second guide wheels 302 are perpendicular to each other, so that the second guide wheel 302 group is used to prevent the fire platform 3 from shaking when axially displacing in the guide rail grooves 102.

[0034] The transmission component 2 includes a lifting rack 201 and a gear 202.
