Abstract
Description
Technical Field
[0001] The utility model relates to a fixing device for a ladder on a tank - type fire truck, belonging to the technical field of fixing devices for extendable ladder components (E06C7 / 06). Background Art
[0002] As a special vehicle, a fire truck is often used to perform fire - fighting, rescue, high - altitude spraying and other emergency tasks. In these tasks, the ladder is particularly crucial as an important high - altitude operation tool. However, there are some inconveniences in the current operation method. Usually, the operator needs to tie the ladder to the side guardrail of the tank - type vehicle with ropes. This method not only reduces the efficiency of fixing and releasing the ladder but also fails to respond promptly in case of an emergency. Especially during emergency operations, additional staff assistance is required, which increases the complexity and risk of the work.
[0003] Therefore, there is an urgent need for a ladder fixing device to improve the convenience of accessing the ladder on the fire truck to cope with emergencies. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is: how to improve the convenience of accessing the ladder on the tank - type fire truck.
[0005] The technical solution proposed by the utility model to solve the above - mentioned technical problem is: a fixing device for a ladder on a tank - type fire truck, which is arranged at least one along the longitudinal direction of the vehicle tank and fixed on the pedal on the longitudinal side of the top of the vehicle tank. The device includes inner legs and outer legs erected in parallel along the transverse direction of the vehicle tank, and front and rear baffles arranged at the head and tail of the top of the vehicle tank respectively; the ladder is placed in the space surrounded by the inner legs, outer legs and the front and rear baffles; the inner legs and the outer legs are fixed by cross - beams, the top of the outer leg is hinged with a pressing plate through a first hinge, the top of the inner leg is hinged with a pressing rod through a second hinge, the top of the inner leg is also hinged with a vertical rod through a third hinge, and the vertical rod is hinged to the second hinge through a fourth hinge; the rotation of the vertical rod drives the up - lift and down - press of the pressing rod.
[0006] Further, a hinge member is fixed at the top of the inner leg, the hinge member and the open end of the split pin form a second hinge, the split pin is provided with a pressing rod near the closed end, and a vertical rod is also arranged in the split pin. The end of the vertical rod higher than the split pin forms a handle.
[0007] Further, the handle end of the vertical rod is hinged to one end of a connecting rod through a fourth hinge, and the other end of the connecting rod is fixed to the split pin.
[0008] Further, pressing strips are fixed on the longitudinal two - side edges of the pressing plate.
[0009] Furthermore, the outer outriggers are in the shape of channel steel and sleeved outside the guardrail posts on the pedals.
[0010] The beneficial effects of the present utility model are as follows: Since the ladder fixing device includes inner outriggers and outer outriggers erected horizontally and in parallel along the transverse direction of the vehicle tank, and front and rear baffles arranged at the head and tail of the top of the vehicle tank respectively, the ladder is placed in the space surrounded by the inner outriggers, outer outriggers and the front and rear baffles, effectively preventing the ladder from being displaced or tilted during transportation. Also, since the inner outriggers and outer outriggers are fixed by cross beams, the stability and rigidity of the fixing device are improved. Moreover, a pressing plate is hinged to the top of the outer outrigger through a first hinge, a pressing rod is hinged to the top of the inner outrigger through a second hinge, and a vertical rod is also hinged to the top of the inner outrigger through a third hinge. The vertical rod is hinged to the second hinge through a fourth hinge. The rotation of the vertical rod drives the pressing rod to lift and lower. The combined action of the pressing plate and the pressing rod ensures that the ladder is firmly fixed and prevents the ladder from falling. The design of multiple hinges enables the fixing device to be easily opened, improving the convenience of accessing the ladder. Description of the Drawings

[0018] Embodiment 1
[0019] A ladder fixing device 1 of a tank fire truck of this embodiment is as follows Figure 1 As shown, a pedal 3 is arranged along the longitudinal direction of the tank 2 and fixed on the longitudinal side of the top of the tank 2, as shown in FIG. Figure 2 As shown, the device includes an inner leg 4 and an outer leg 5 erected in parallel along the transverse direction of the tank 2, and two front and rear baffles 6 arranged at the head and tail of the top of the tank 2; the ladder 7 is placed in the space surrounded by the inner leg 4, the outer leg 5 and the front and rear baffles 6; the inner leg 4 and the outer leg 5 are fixed by a crossbeam 8, as shown in FIG. Figure 3 , 4 As shown, the top of the outer leg 5 is hinged with a pressure plate 10 through a first hinge 9, the top of the inner leg 4 is hinged with a clamping rod 12 through a second hinge 11, and the top of the inner leg 4 is also hinged with a vertical rod 14 through a third hinge 13, and the vertical rod 14 is hinged to the second hinge 11 through a fourth hinge 15; the rotation of the vertical rod 14 drives the clamping rod 12 to be lifted up and pressed down.
[0020] like Figure 4 As shown, a hinge 16 is fixed to the top of the inner leg 4, and the hinge 16 and the open end of the cotter pin 17 form a second hinge 11. A clamping rod 12 is passed through the cotter pin 17 near the closed end, and a vertical rod 14 is also passed through the cotter pin. The vertical rod 14 is higher than one end of the cotter pin 17 to form a handle.
[0021] like Figure 4 As shown, the handle end of the vertical rod 14 is hinged to one end of the connecting rod 18 through the fourth hinge 15, and the other end of the connecting rod 18 is fixed to the cotter pin 17. When in use, you only need to hold the handle on the vertical rod 14 and rotate it to lift the clamping rod 12, and then lift the pressure plate 10 to take out the ladder 7, which facilitates the storage and retrieval of the ladder 7.
[0022] like Figure 3 As shown, pressure strips 19 are fixed to both longitudinal edges of the pressure plate 10 to increase the contact area with the ladder 7 and prevent the ladder 7 from being compressed and deformed.
[0023] like Figure 2 As shown, the outer leg 5 is designed to be channel-shaped and sleeved outside the guardrail column 20 on the pedal 3, saving space.
