Description

Technical Field

[0001] The utility model belongs to the technical field of rescue equipment, and particularly relates to a tail plate structure of a boarding rescue vehicle. Background Art

[0002] A boarding rescue vehicle is a special vehicle used for aviation emergency rescue. Such vehicles are usually used for emergency rescue work at airports, such as rescue operations at the scene of an aircraft accident. The design purpose of this kind of vehicle is to quickly approach the aircraft and provide an emergency evacuation passage or other forms of rescue services for passengers and crew members. In the prior art, when using a boarding rescue vehicle, a tail plate is needed to connect the end of the rescue ladder of the boarding rescue vehicle to the ground to form a passage so that passengers and crew members can safely reach the ground.

[0003] Currently, the tail plates in the prior art are mostly seen in truck tail plates and are used to carry goods. Therefore, they are all folded in one section and have a large slope after being opened. However, as long as the goods can be transported quickly, comfort is not concerned. Even if there are very few two-section folds, a flat surface cannot be formed after being opened. Therefore, this kind of tail plate is not suitable for use with a boarding rescue vehicle. In addition, an ordinary plate structure cannot be well matched with a boarding rescue vehicle and there are safety hazards. To sum up, it is necessary to develop a tail plate structure of a boarding rescue vehicle that can be effectively combined with a boarding rescue vehicle. Summary of the Utility Model

[0004] The utility model aims at the above problems, makes up for the deficiencies of the prior art, and provides a tail plate structure of a boarding rescue vehicle.

[0005] To achieve the above object, the utility model adopts the following technical solutions.

[0006] A tail plate structure of a boarding rescue vehicle provided by the utility model includes an upper pedal, a lower pedal, and a hinge mechanism. One end of the upper pedal is connected to one end of the lower pedal through the hinge mechanism; both sides of the other end of the upper pedal are connected with turning cylinders. Both the upper pedal and the lower pedal are composed of anti-slip profile structural plates. Grooves are formed on the anti-slip profile structural plates, and anti-slip convex ribs are arranged on the surfaces of the anti-slip profile structural plates.

[0007] Furthermore, a protective cover is provided on the hinge mechanism.

[0008] Furthermore, the hinge mechanism includes a first hinge shaft, a second hinge shaft, and a small arm oil cylinder. The first hinge shaft is symmetrically fixed on both sides of the lower pedal, the second hinge shaft is symmetrically fixed on both sides of the upper pedal, one end of the small arm oil cylinder is rotatably connected to the first hinge shaft, and the other end of the small arm oil cylinder is rotatably connected to the second hinge shaft.

[0009] Furthermore, an inclined end face is provided at the bottom of the other end of the lower pedal.

[0010] Furthermore, equidistant grooves with a width of 1 cm are formed in the anti-slip profile structure plate.

[0011] Advantages of the utility model:

[0012] The tail plate structure of the boarding rescue vehicle provided by the utility model complements the rescue ladder of the boarding rescue vehicle, and builds a safe passage for personnel to board the plane or evacuate emergently. By using the small arm oil cylinder to control the upper pedal and the lower pedal to unfold into a plane, the contact angle between the entire tail plate structure and the ground can be controlled by flipping; at the same time, both the upper pedal and the lower pedal of the utility model are composed of anti-slip profile structure plates, which can effectively help personnel board the plane or evacuate emergently quickly and safely.

Specific implementation manners

[0020] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model clearer, the following further details the utility model in combination with the accompanying drawings and specific implementation manners. It should be understood that the specific implementation manners described herein are only used to explain the utility model and are not used to limit the utility model.

[0021] Combined Figures 1 to 6 As shown, a tail board structure of a boarding rescue vehicle provided by an embodiment of the present utility model includes an upper pedal 3, a lower pedal 2, and a hinge mechanism. One end of the upper pedal 3 is connected to one end of the lower pedal 2 through the hinge mechanism; both sides of the other end of the upper pedal 3 are connected with a tipping cylinder 1. Both the upper pedal 3 and the lower pedal 2 are composed of an anti-slip profile structural plate 9. Grooves 10 are formed on the anti-slip profile structural plate 9, and anti-slip ridges 11 are arranged on the surface of the anti-slip profile structural plate 9; a protective cover 4 is covered on the hinge mechanism.

[0022] The hinge mechanism includes a first hinge shaft 5, a second hinge shaft 7, and a small arm cylinder 6. The first hinge shaft 5 is symmetrically fixed on both sides of the lower pedal 2, the second hinge shaft 7 is symmetrically fixed on both sides of the upper pedal 3, one end of the small arm cylinder 6 is rotatably connected to the first hinge shaft 5, and the other end of the small arm cylinder 6 is rotatably connected to the second hinge shaft 7.

[0023] An inclined end face 8 is arranged at the bottom of the other end of the lower pedal 2, and the inclined end face 8 can be well matched with the ground for contact.

[0024] The anti-slip profile structural plate 9 is provided with grooves 10 with a width of 1 cm at equal intervals.

[0025] Specifically, the tail board structure of the boarding rescue vehicle of the present utility model mainly includes two parts, an upper pedal 3 and a lower pedal 2. The upper pedal 3 is connected with the tipping cylinder 1, and the tipping cylinders 1 are symmetrically arranged on the left and right. The lower pedal 2 is connected with the upper pedal 3 through the small arm cylinder 6. Both ends of the small arm cylinder 6 are respectively connected to the first hinge shaft 5 and the second hinge shaft 7. In this way, during the movement of the small arm cylinder 6, the lower pedal 2 can be driven to unfold; in addition, the outside of the small arm cylinder 6 is protected by the protective cover 4, which can effectively prevent rain erosion.

[0026] The anti-slip effect of the anti-slip profile structural plate 9: As Figures 4 to 6 shown, the anti-slip ridges 11 arranged on the upper surface of the anti-slip profile structural plate 9 can well increase the anti-slip effect; the grooves 10 formed on the anti-slip profile structural plate 9 can effectively expose the drainage channels, which is beneficial to the drainage of the upper surfaces of the upper pedal 3 and the lower pedal 2.

[0027] Describe its usage method and working principle in combination with the technical solution of the present utility model and the attached drawings: The tail plate structure of the boarding rescue vehicle of the present utility model is used in combination with the boarding rescue vehicle; specifically, the tail plate structure of the boarding rescue vehicle is installed at the tail end of the rescue ladder of the boarding rescue vehicle through the tilting cylinder 1; in this way, the tail plate structure of the boarding rescue vehicle of the present utility model and the rescue ladder of the boarding rescue vehicle can complement each other to form a safe passage for personnel to board the plane or evacuate emergently. By using the small arm cylinder 6, the upper pedal 3 and the lower pedal 2 are controlled to unfold into a plane, and by using the tilting cylinder 1, the contact angle between the entire tail plate structure and the ground can be controlled. At the same time, both the upper pedal 3 and the lower pedal 2 are composed of anti-slip profile structural plates 9, which can effectively help personnel board the plane or evacuate emergently quickly and safely.

[0028] According to the action process of the tilting cylinder 1 and the small arm cylinder 6, describe the corresponding states of the tail plate structure of the boarding rescue vehicle of the present utility model: When the tilting cylinder 1 extends and the small arm cylinder 6 retracts, the entire tail plate structure is retracted and is in a state perpendicular to the ground, that is, vertically erected at the tail end of the rescue ladder of the boarding rescue vehicle, as Figure 1 shown; when the tilting cylinder 1 retracts and the small arm cylinder 6 extends, the entire tail plate structure is opened and contacts the ground at a certain angle, as Figure 3 shown. The small arm cylinder 6 can fold the upper pedal 3 and the lower pedal 2 to form a plane for personnel to step on this plane.

[0029] The main function of the tail plate structure of the boarding rescue vehicle provided by the present utility model is to carry people. When the plane at the airport is in an emergency state, personnel evacuate from the constructed passage, and this tail plate structure of the boarding rescue vehicle is an important section at the end of the constructed passage. The tail plate structure of the boarding rescue vehicle of the present utility model is in a folded form of the pedal 3 and the lower pedal 2, and forms a plane after being opened. Moreover, the passage formed after the pedal 3 and the lower pedal 2 are unfolded is relatively long, so the finally formed slope is very small, making it more comfortable, easy and convenient for personnel to walk and evacuate.

[0030] It can be understood that the above specific description of the present utility model is only for explaining the present utility model and is not limited to the technical solution described in the embodiments of the present utility model. Those of ordinary skill in the art should understand that the present utility model can still be modified or equivalently replaced to achieve the same technical effect; as long as it meets the usage requirements, it is within the protection scope of the present utility model.
