Description

Technical Field

[0001] This utility model relates to the field of fire rescue technology, and in particular to fire truck landing gear. Background Technology

[0002] Fire truck landing gear, a critical piece of equipment ensuring the safety of fire truck operations, is primarily used to extend and adjust the support height and distribute the vehicle's weight when deploying rescue equipment such as ladders and high-pressure water cannons, preventing tilting caused by a shift in the center of gravity. Its core structure includes a main frame, telescopic columns, and support bases, and must be adaptable to complex rescue scenarios. With the increasing demand for high-rise rescues, the requirements for structural stability and operational reliability of landing gear have increased. While current mainstream designs have optimized load-bearing strength and telescopic flexibility, a complete solution has not yet been developed for the positional constraints and fixed states of key components, making it difficult to fully cope with the dynamic forces and bumpy conditions encountered during rescue operations.

[0003] The core defects of the existing technology are: the fire truck landing gear is not equipped with a fixed limiting device, and the telescopic column is only fixed by hydraulic locks or simple buckles after it is deployed. It is easy to move and shift under the vibration of operation and external impact. When it is retracted, there is no restraint. When it is bumpy during driving, it will collide and wear with the frame, causing the parts to loosen, affecting the stability of the support and shortening the service life. Utility Model Content

[0004] The purpose of this utility model is to provide a fire truck landing gear, which aims to solve the problem mentioned above where the components become loose due to wear and tear from collisions with the frame during bumpy driving, affecting the stability of the support and shortening its lifespan.

[0005] The technical solution adopted in this utility model is as follows:

[0006] Fire truck landing gear, including:

[0007] The main frame pipes are equipped with mounting holes;

[0008] The longitudinal main beam is located on the upper side of the main frame pipe;

[0009] Telescopic column tubes are installed on the upper side of the longitudinal main beam;

[0010] The equipment mounting bracket is installed between the main frame pipe and the telescopic column pipe;

[0011] A support base is installed on the lower side of the telescopic column tube.

[0012] This utility model also has the following technical features:

[0013] In one embodiment of this utility model, the inner walls of the main frame tube and the longitudinal main beam are equipped with reinforcing ribs.

[0014] In one embodiment of this utility model, a lifting beam is installed on the inner wall of the telescopic column tube, a hydraulic valve is fixed on the upper side of the lifting beam, a hydraulic rod is fixed on the upper side of the hydraulic valve, a lifting slider is fixed at the upper end of the hydraulic rod, and the lifting slider is fixedly connected to the inner wall of the telescopic column tube.

[0015] In one embodiment of this utility model, a data interface is provided on the right side surface of the switch body, an electromagnetic valve is fixed on the upper side of the lifting beam, a wire is installed above the electromagnetic valve, and the wire is connected to the telescopic column and the equipment mounting bracket.

[0016] In one embodiment of this utility model, the left and right outer walls of the telescopic column tube are equipped with ladder-type locking plates, and the ends of the ladder-type locking plates are provided with slots.

[0018] In one embodiment of the present invention, a hinge is installed on the right side of the support base, a limiting plate is installed at the end of the hinge, and a locking tongue is installed on the upper side of the limiting plate.

[0019] In one embodiment of this utility model, elastic bands are installed on the left and right sides of the limiting plate, and hooks are installed on the upper ends of the elastic bands.

[0020] Compared with existing technologies, the beneficial effects of this utility model are reflected in the following: By opening mounting holes in the main frame tubing, precise benchmarks can be provided for component assembly, avoiding deviations and thus improving the overall structural stability. The longitudinal main beam, located on its upper side, can bear the force transmission and stably support the telescopic column tube, ensuring structural reliability during height adjustment. The telescopic column tube, combined with the lifting beam, hydraulic valve, and rod, can stably adjust height, adapt to different terrains, and solve the support problems of complex sites. Equipment mounting brackets are provided between the main frame and the column tube, providing dedicated space for supporting equipment, preventing interference, and ensuring the coordinated operation of all components. The support base is installed on the lower side of the column tube, ensuring stable grounding, preventing slippage during operation, and improving support safety. Reinforcing ribs are installed on the inner walls of the main frame and main beam, enhancing strength and resistance to deformation, and preventing long-term deformation under stress. Locking plates with grooves are installed on the outer walls of the column tube, limiting the adjustment position, preventing unexpected displacement, and ensuring reliable height fixation. The support base is equipped with anti-slip pads, hinges, and limit plates, along with elastic bands and hooks, which can enhance restraint, prevent displacement and loosening, and strengthen overall stability.

[0031] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0032] The illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0033] It should be noted that the core defect of existing fire truck landing gear is that the landing gear wears down due to collisions with the frame during bumpy driving, causing components to loosen, affecting support stability and shortening lifespan. To address this, a fire truck landing gear is proposed that includes a main frame tube 10 with mounting holes; a longitudinal main beam 20 located on the upper side of the main frame tube 10; a telescopic column tube 30 installed on the upper side of the longitudinal main beam 20; an equipment mounting bracket 40 located between the main frame tube 10 and the telescopic column tube 30; and a support base 50 installed on the lower side of the telescopic column tube 30.

[0034] In one embodiment, the inner walls of the main frame pipe 10 and the longitudinal main beam 20 are equipped with reinforcing ribs 11. The reinforcing ribs 11 are connected to the inner walls of the main frame pipe 10 and the longitudinal main beam 20, which can enhance the structural strength of the connection between the two, disperse stress, prevent the main frame pipe 10 and the longitudinal main beam 20 from deforming or breaking under stress, and improve the load-bearing capacity of the overall frame.

[0035] In one embodiment, a lifting beam 31 is installed on the inner wall of the telescopic column tube 30. A hydraulic valve 32 is fixed to the upper side of the lifting beam 31, and a hydraulic rod 33 is fixed to the upper side of the hydraulic valve 32. A lifting slider 34 is fixed to the upper end of the hydraulic rod 33. The lifting slider 34 is fixedly connected to the inner wall of the telescopic column tube 30. The lifting beam 31 provides an installation base for the hydraulic valve 32. The hydraulic valve 32 controls the extension and retraction of the hydraulic rod 33. The hydraulic rod 33 transmits force to the telescopic column tube 30 through the lifting slider 34. The lifting and lowering action of the telescopic column tube 30 is realized by utilizing the fixed connection between the lifting slider 34 and the inner wall of the telescopic column tube 30.

[0036] In one embodiment, a solenoid valve 35 is fixed to the upper side of the lifting beam 31, and a wire 36 is installed above the solenoid valve 35. The wire 36 is connected to the telescopic column tube 30 and the equipment mounting bracket 40. The lifting beam 31 provides mounting support for the solenoid valve 35. The wire 36 connects the solenoid valve 35 to the telescopic column tube 30 and the equipment mounting bracket 40 for transmitting electrical signals, so that the solenoid valve 35 can receive control commands from relevant equipment, and then cooperate with the hydraulic system to adjust the working state of the telescopic column tube 30.

[0037] In one embodiment, the left and right outer walls of the telescopic column tube 30 are equipped with ladder-type locking plates 37, and the ends of the ladder-type locking plates 37 are provided with slots 38.

[0038] In one embodiment, an anti-slip pad 51 is installed on the upper side of the support base 50. The anti-slip pad 51 is installed on the upper side of the support base 50 to increase the friction between the support base 50 and the object placed on it, thereby preventing the object placed on the support base 50 from sliding, enhancing the stability of the object placement, and also providing some protection for the bottom of the object.

[0039] In one embodiment, a hinge 52 is installed on the right side of the support base 50, a limiting plate 60 is installed at the end of the hinge 52, and a locking tongue 61 is installed on the upper side of the limiting plate 60.

[0040] In one embodiment, elastic bands 62 are installed on the left and right sides of the limiting plate 60, and hooks 63 are installed on the upper end of the elastic bands 62.

[0041] In one embodiment, see Figure 1 and Figure 2The ladder-type locking plate 37 serves as the basic locking component of the telescopic column tube 30. Through its fixed connection with the telescopic column tube 30, the slot 38 can engage with the corresponding mating component. When the telescopic column tube 30 is raised or lowered to the required position, the engagement of the slot 38 with the mating component directly locks the position of the telescopic column tube 30, thereby preventing it from sliding accidentally during operation and ensuring the stability of the overall structure in the height direction.

[0042] In one embodiment, the hinge 52 provides a rotatable connection fulcrum for the limiting plate 60, allowing the limiting plate 60 to adjust its angle and position according to the placement requirements of the object on the support base 50. When the limiting plate 60 rotates to a suitable limiting position, its upper locking tongue 61 cooperates with the corresponding locking structure to fix the limiting plate 60 in that position. At this time, the limiting plate 60 can form a lateral obstruction to the object on the support base 50, completing the initial limiting and fixing.

[0043] In another embodiment, see Figure 3 The elastic band 62, relying on its connection with the limiting plate 60, can flexibly adapt to objects of different sizes by utilizing its own elastic properties. When the object is placed on the support base 50 and initially limited by the limiting plate 60, the elastic band 62 will generate a tightening force on the object by connecting the hook 63 at the upper end of the elastic band 62 to the support base 50 or other fixed parts. This will work in conjunction with the limiting plate 60 to enhance the constraint on the object from multiple directions, further preventing the object from shaking or falling, and achieving a more stable fixing effect.

[0044] In summary, the fire truck landing gear of this utility model, through the coordinated action of the ladder-type locking plate 37, the slot 38, the hinge 52, the limiting plate 60 and the locking tongue 61, can further secure the object to the support base 50, thus realizing the reliable fixing function of the landing gear itself and the object it carries.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
