It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0024] See also Figure 1-5 The utility model provides a technical solution: a fire-fighting construction crane, comprising a lifting mechanism 1 and a fixing mechanism 2, the fixing mechanism 2 is slidably connected to the inner wall of the lifting mechanism 1, the lifting mechanism 1 comprises a hydraulic rod 101, a limiting groove 102 and a U-shaped frame 103, and the fixing mechanism 2 comprises a limiting component 201 and an adjusting component 202;

[0025] The hydraulic rod 101 is bolted to the bottom of the inner wall of the limiting groove 102. The limiting groove 102 is opened on both sides of the inner wall of the U-shaped frame 103. The inner wall of the limiting groove 102 is slidably connected to the outer side of the limiting component 201. The two sides of the bottom of the limiting component 201 are bolted to the output end of the hydraulic rod 101, and the adjustment component 202 is slidably connected to the inner wall of the limiting component 201.

[0026] In this embodiment, by setting the lifting mechanism 1 and the fixing mechanism 2, after the hydraulic rod 101 is started, it can be pushed upward in the limit groove 102. Because the hydraulic rod 101 fixes the limit assembly 201, the hydraulic rod 101 drives the limit assembly 201 to move in the limit groove 102 during the advancement process. The U-shaped frame 103 can fix the limit groove 102 and limit the limit assembly 201 to prevent the limit assembly 201 from shifting when the hydraulic rod 101 drives it to move. The limit assembly 201 can adjust the position of the limit assembly 201. Component 202 is used to fix and limit, and when the limiting component 201 moves, the limiting component 201 fixes the adjusting component 202, so that the limiting component 201 drives the adjusting component 202 to move. After the adjusting component 202 is powered on, the fire-fighting pipe can be fixed, and the fire-fighting pipe can be lifted by the movement of the limiting component 201. The fixing of the adjusting component 202 can prevent the fire-fighting pipe from shaking and falling off after lifting. After the adjusting component 202 is adjusted, fire-fighting pipes of different sizes can be fixed.

[0027] As a technical optimization solution of the utility model, the limit assembly 201 includes an adjusting groove 2011, a limit plate 2012 and a fixed block 2013. The adjusting groove 2011 is opened at the top of the limit plate 2012. The right side of the top of the limit plate 2012 is bolted to the bottom of the fixed block 2013. The two sides of the limit plate 2012 are slidably connected to the inner wall of the limit groove 102. The two sides of the bottom of the limit plate 2012 are bolted to the output end of the hydraulic rod 101.

[0028] In this embodiment: by setting the limit component 201, the adjustment groove 2011 can limit and fix the adjustment component 202, and can increase the stability of the adjustment component 202 when in use; the limit plate 2012 can fix the adjustment groove 2011, and can fix the fixed block 2013, so that the stability of the fixed block 2013 when in use is increased; the fixed block 2013 can fix the adjustment component 202, and under the fixation of the limit plate 2012, the adjustment position of the adjustment component 202 can be limited to avoid the adjustment position of the adjustment component 202 from being offset.

[0029] As a technical optimization scheme of the utility model, the adjustment component 202 includes a forward and reverse motor 2021, a bidirectional screw rod 2022, a T-shaped block 2023 and a clamping block 2024. The surface of the forward and reverse motor 2021 is bolted to the left side of the top of the limit plate 2012, the output end of the forward and reverse motor 2021 is bolted to one end of the bidirectional screw rod 2022, the surface of the bidirectional screw rod 2022 is rotatably connected to the inner wall of the T-shaped block 2023, the other end of the bidirectional screw rod 2022 is rotatably connected to the left side of the fixed block 2013, the two sides of the T-shaped block 2023 are slidably connected to the two sides of the inner wall of the adjustment groove 2011, and the bottom of the T-shaped block 2023 is bolted to the top of the clamping block 2024.

[0030] In this embodiment: by setting the adjustment component 202, after the forward and reverse motor 2021 is powered on and started, the limit plate 2012 can be fixed to convert electrical energy into kinetic energy, and the kinetic energy can be transferred to the bidirectional screw rod 2022 to make it rotate. When the bidirectional screw rod 2022 rotates, the bidirectional screw rod 2022 fixes the T-shaped block 2023, so that the T-shaped block 2023 can move on the bidirectional screw rod 2022. Since the T-shaped block 2023 fixes the clamping block 2024, the T-shaped block 2023 can move while driving the clamping block 2024 to move, thereby achieving the fixation of the fire hose.

[0031] As a technical optimization solution of the utility model, reinforcement blocks 3 are provided on both sides of the U-shaped frame 103 . The reinforcement blocks 3 are made of stainless steel material and are used in conjunction with the U-shaped frame 103 .

[0032] In this embodiment: by setting the reinforcement block 3, the U-shaped frame 103 can be reinforced and protected, and the reinforcement block 3 is made of stainless steel material, which has strong hardness and service life, and can increase the stability of the reinforcement block 3 and the U-shaped frame 103 when in use.

[0033] As a technical optimization solution of the present invention, a moving wheel 4 is provided at the bottom of the U-shaped frame 103 , and a total of four moving wheels 4 are provided, and the moving wheels 4 are used in conjunction with the U-shaped frame 103 .

[0034] In this embodiment, by providing the moving wheels 4, the user can push the U-shaped frame 103 to a desired position, thereby facilitating the lifting of the fire hose.

[0035] As a technical optimization solution of the utility model, a connecting hole 5 is provided on the left side of the fixing block 2013 . The connecting hole 5 is designed to be circular and is used in conjunction with the fixing block 2013 .

[0036] In this embodiment: by providing the connection hole 5, the fixing block 2013 can be easily connected and installed, and the connection hole 5 can increase the stability of the connection of the fixing block 2013 to avoid shaking and falling off of the connection.

[0037] As a technical optimization solution of the present utility model, a protective pad 6 is provided on the surface of the clamping block 2024 , and a buckle structure is provided on the surface of the protective pad 6 , and the protective pad 6 is used in conjunction with the clamping block 2024 .

[0038] In this embodiment: the clamping block 2024 can be protected by providing a protective pad 6, and a snap structure is provided on the surface of the protective pad 6 to facilitate the removal of the protective pad 6, thereby facilitating the inspection and maintenance of the clamping block 2024.

[0039] Working principle: First, push the U-shaped frame 103 to the desired position, then align the clamping block 2024 with the fire hose to be clamped, and then power on the forward and reverse motor 2021. After the forward and reverse motor 2021 is powered on and started, the electrical energy can be converted into kinetic energy under the fixation of the limit plate 2012, and the kinetic energy is transferred to the bidirectional screw rod 2022 to rotate. Because the bidirectional screw rod 2022 fixes the T-shaped block 2023, the T-shaped block 2023 moves on the bidirectional screw rod 2022 when the bidirectional screw rod 2022 rotates, and because the adjustment slot 2011 limits the T-shaped block 2023, the T-shaped block 2023 moves. The moving position will not be offset. After the clamping block 2024 fixes the fire pipe, the hydraulic rod 101 is started. After the hydraulic rod 101 is started, it can be pushed upward under the fixation of the limit groove 102. Because the hydraulic rod 101 fixes the limit plate 2012, the hydraulic rod 101 can drive the limit plate 2012 to move in the limit groove 102 while being pushed forward. Subsequently, driven by the limit plate 2012, the adjustment component 202 drives the fixed fire pipe to be lifted in the U-shaped frame 103, and then the lifted fire pipe is moved to the desired position through the moving wheel 4 for installation until the installation of the fire pipe is completed.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
