Description

Technical Field

[0001] The utility model relates to the technical field of deicing vehicles, in particular to an anti-collision device and an aircraft deicing vehicle. Background Technique

[0002] The aircraft deicing vehicle is an essential guarantee equipment for the normal operation of aircraft in winter. The aircraft deicing vehicle uses an aerial work arm to transport deicing personnel to the upper part of the aircraft, and sprays the heated deicing fluid onto the aircraft surface through a spray gun to deice the aircraft surface. During the deicing operation, a certain working distance needs to be maintained between the aerial work cabin body and the aircraft surface to prevent accidents of rubbing against the aircraft. A limit sensor is usually installed at the bottom of the work cabin. When the limit sensor contacts the aircraft, limit protection is carried out to stop the boom movement and prevent rubbing against the aircraft. Currently, there are two common types of limit sensors. One is the deicing vehicle with an auxiliary anti-collision system disclosed in Chinese Patent CN213735614 U. By setting ranging sensors and inclination sensors on the head and boom of the deicing vehicle, multi-directional auxiliary monitoring reduces and improves collision accidents. Its disadvantages are: the ranging range is relatively short, the deicing vehicle may hit the aircraft because it cannot avoid in time, and the working arm of the deicing vehicle may also hit the aircraft due to inertia and be out of control, affecting the safety of the aircraft; the other is an ultrasonic limit sensor, such as the anti-collision intelligent auxiliary system for airport deicing vehicles disclosed in Chinese Patent CN217892671U. Its anti-collision mechanism includes a camera group, an ultrasonic radar group, an alarm, a display screen, a brake and a host. Its disadvantages are: in actual application, the electromagnetic environment at the airport is complex, ultrasonic waves are easily affected by electromagnetic interference, and rain, snow and deicing fluid will interfere with the ultrasonic sensor during the deicing process, resulting in false alarms and affecting the operation safety.

By providing the fixed seat and the sensing plate, it is convenient to install the movable hemisphere, the spring pressing plate, and the spring.

[0025] The rear end of the fixing base 12 of the utility model is threadedly connected to the induction plate 13, which is convenient for disassembly and assembly.

[0026] An aircraft de-icing vehicle, comprising an automobile chassis and an aerial work cabin, characterized in that: an anti-collision device as described above is provided on one side of the aerial work cabin, the induction housing 6 is fixedly connected to the aerial work cabin, and the induction switch 11 is connected to the control system on the automobile chassis. By setting the anti-collision device on the aerial work cabin, after the ball head contacts an obstacle, the ball head pushes the support rod, the support rod pushes the movable hemisphere, the spring pressing plate is pushed, the spring pressing plate moves upward to compress the spring, the front end face of the induction switch passes through the perforation of the spring pressing plate and contacts the movable hemisphere, and the movable hemisphere presses the induction switch. When the pressure is greater than the set value of the induction switch, the induction switch transmits a signal to the de-icing vehicle to control the de-icing vehicle to stop the de-icing operation.

[0027] As shown in the appendix Figure 1 , before use, the fixing base 12 and / or the induction plate 13 are fixed to one end of the aerial work cabin facing the aircraft. The length of the support rod 1 can be set according to requirements. By extending the support rod, the induction length is extended, realizing long-distance induction, and leaving more reaction time for the de-icing vehicle to stop the operation of the de-icing operation arm on the de-icing vehicle, avoiding the de-icing operation arm of the de-icing vehicle from hitting the aircraft. For the convenience of description, taking the orientation shown in the appendix Figure 1 as an example, the ball head 4 is in the front, the induction housing 6 is in the rear, and the support rod 1 is located between the two. The ball head 4 can be made of soft and elastic materials such as nylon material, polyurethane material, and silicone rubber material. Before use, a fixed rubber pad can be further wrapped on the surface of the ball head 4, and the rubber pad can further protect the outer wall of the aircraft.

[0028] During use, the ball head 4 faces the aircraft. When the ball head 4 contacts the aircraft, the aircraft will squeeze the ball head 4, causing the ball head 4 to swing. As the contact further increases, the outer wall of the aircraft will squeeze the ball head 4 to move backward. The connecting seat 5 fixed to the rear end of the ball head 4 is hinged to the support rod 1 through a pin shaft, so that the ball head 4 can swing up and down relative to the support rod 1. After the ball head 4 moves backward, it causes the support rod 1 to move backward. The support rod 1 is fixed to the connecting rod 10, and the connecting rod 10 is fixed to the movable hemisphere 7. The support rod 1 drives the connecting rod 1 and the movable hemisphere 7 to move backward. The movable hemisphere 7 moves backward to push the spring pressing plate 8, and the spring pressing plate 8 slides backward along the induction switch 11 through the perforation guide. As shown in the appendix Figure 1, the perforation has a certain length. The width of the rear part of the induction switch 11 is greater than that of the front part of the induction switch 11. The front part of the induction switch 11 is slidably connected to the perforation. In the initial state, the spring 9 is not compressed and is in a natural elongation state. The front end of the induction switch 11 is located at the rear end of the inner wall of the perforation, and the front end of the induction switch 11 does not protrude from the spring pressing plate 8. There is a certain distance between the spring pressing plate 8 and the movable hemisphere 7. As the spring pressing plate 8 moves backward, the front end of the induction switch 11 protrudes from the perforation, and the front end of the induction switch 11 contacts the movable hemisphere 7 and is squeezed by the movable hemisphere 7. When the pressure is greater than the set value of the induction switch 11, the induction switch 11 is triggered. The induction switch 11 transmits a signal to the control system of the deicing vehicle, and the control system controls the deicing operation arm to stop moving to avoid hitting the aircraft. When the spring pressing plate 8 moves backward, it will also squeeze the spring 9, causing the spring 9 to generate a resilience force. When the control system controls the deicing vehicle to move away from the aircraft, the ball head 4 does not contact the aircraft. The spring pressing plate 8 moves forward under the action of the resilience force of the spring 9, so that the front end of the induction switch 11 no longer protrudes from the spring pressing plate 8. The spring pressing plate 8 moves forward to push the movable hemisphere 7 forward, and the movable hemisphere 7 no longer squeezes the induction switch 11, and the induction is released.

[0029] The front end face of the induction housing 6 of the present utility model is provided with arc-shaped grooves, which are arranged up and down and are consistent with the up and down swinging direction of the ball head 4. This enables the support rod 1 to drive the movable hemisphere 7 to rotate slightly up and down with the center of the movable hemisphere 7 as the center when the support rod 1 swings with the ball head 4. Since the spring pressing plate 8 is slidably connected to the inner wall of the induction housing 6, even if the movable hemisphere 7 rotates, as long as the movable hemisphere 7 touches the spring pressing plate 8, it will squeeze the spring pressing plate 8 to make the spring pressing plate 8 move backward, and the front end of the induction switch 11 protrudes from the perforation or the front end face of the induction switch 11 is flush with the front end face of the spring pressing plate 8. The movable hemisphere 7 continues to move backward, squeezing the spring pressing plate 8 and at the same time squeezing the induction switch 11, triggering the induction switch 11, with sensitive reaction and timely response; the structure of the present utility model is ingenious, and the induction distance is extended through the support rod 1. The present utility model triggers the induction switch 11 after the ball head 4 touches the aircraft, is not affected by electromagnetic signals, can quickly, effectively and timely stop the deicing vehicle operation arm, avoid rubbing against the aircraft, and has high safety. In addition, in the present utility model, the connecting rod 10 is threadedly connected to the movable hemisphere 7, the connecting rod 10 is threadedly connected to the support rod 1, and the fixing seat 12 is threadedly connected to the induction plate 13, which is convenient for disassembly and assembly, convenient for maintenance and replacement of components, and has low use cost.

[0030] Due to the adoption of the above structure, the present utility model has the advantages of ingenious structure, long-distance induction, immunity to electromagnetic signals, timely response, and high safety.
