Description
Technical Field
[0001] The invention relates to the technical field of aircraft safety, and in particular to an aircraft bridge safety boot control and protection device. Background Art
[0002] At present, when domestic and foreign passenger boarding bridges are docking with aircraft, the aircraft fuselage moves up and down due to the change of its own load during the support operation when the aircraft is docked on the apron. It is required that a certain distance should be maintained between the open aircraft cabin door and the corridor bridge receiving platform. The follow-up leveling wheel on the corridor bridge is used to track the change of the aircraft fuselage and adjust the height of the corridor bridge receiving platform in real time to meet a certain gap. In order to prevent the risk of damage to the aircraft caused by uncontrollable factors such as failure of the follow-up leveling wheel on the corridor bridge or misoperation of personnel, a safety boot with a touch switch is usually added. This safety boot is placed between the bottom of the lower edge of the aircraft cabin door and the corridor bridge receiving platform. Its function is to replace the follow-up leveling wheel with a safety boot to complete the safety prevention function when the follow-up leveling wheel fails.
[0003] In order to realize the safety prevention function of safety boots, the requirements for the placement and fixing position of safety boots are stipulated. According to whether the safety boots are fixed at the working position or not, they are divided into fixed and mobile types. The safety boots are fixed at their working position and do not need to be taken out from the storage place and placed in the working area every time, which can reduce the placement of operators and also provide technical conditions for unmanned operation of the corridor. The safety boots are moved to the working position, and the operator needs to take them out from the storage place and place them in the working area every time. Regardless of whether fixed or mobile safety boots are placed in the working area, eye-catching warning signs are placed in the working area to prevent staff or passengers from touching the safety boots. Even if eye-catching warning signs are placed in the safety boots working area, safety issues caused by the safety boots being touched will still occur.
[0004] During operation, after the jet bridge docks with the aircraft, the aircraft door is opened, and then the mobile safety boots are placed at the bottom of the lower edge of the aircraft door and fixed in place in accordance with the operating requirements. Safety boots with sufficient weight are used to ensure that the safety boots do not move accidentally. An alarm device must also be set up to give an audible and visual alarm when the safety boots move out of the effective working position. The fixed safety boots only need to have their effective contact area within the contact range of the bottom of the lower edge of the aircraft door.
[0005] However, whether they are mobile or fixed, there is a safety risk of being accidentally touched by the bridge operator, aircraft crew or passenger, because there is no effective protection for the safety boots, and the risk of being touched cannot be avoided. As a result, the bridge control will receive an erroneous signal, causing the bridge to move up and down, causing a safety incident of damaging the aircraft cabin door. Therefore, in order to solve this problem, the present invention provides a bridge safety boot control and protection device, which can avoid malfunction of the bridge and damage to the aircraft due to various reasons. Summary of the invention
[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0007] A bridge safety boots protection device, comprising a safety boot or a safety boot assembly, which is installed on a base, one end of a multi-section telescopic protective cover is fixedly installed on the base, the other end of the multi-section telescopic protective cover is connected to one end of an electric reciprocating telescopic rod device for driving a protective cover through a protective cover connecting seat, the other end of the electric reciprocating telescopic rod device is fixed on the base, and the multi-section telescopic protective cover is driven to telescopically move by the telescopic rod of the electric reciprocating telescopic rod device, and a cross laser instrument, a first micro-touch switch, and a laser measuring device are installed on the upper front end of the multi-section telescopic protective cover. The cross laser instrument is used as an indicator mark when the corridor bridge docks with the bottom of the lower edge of the aircraft door and the left edge of the aircraft door. The first micro-touch switch is used for safety redundancy control during the telescopic movement of the multi-section telescopic protective cover. The laser rangefinder is used as a detection device to detect the distance between the end of the multi-section telescopic protective cover and the aircraft door in real time. The sound and light alarm device is used to warn external personnel to pay attention to the fact that this safety boot is in working condition and must not be touched or approached. When the multi-section telescopic protective cover starts to work, its sound and light alarm device works at the same time to emit sound and light warnings.
[0008] Furthermore, the infrared marking line emitted by the cross laser instrument hits the aircraft fuselage, aligning with the lower edge of the aircraft door and the left side contour line of the door, while also displaying the originally set safety distance height difference between the jet bridge floor and the lower edge of the aircraft door, which can ensure that the safety boots or safety boot components are within the effective use range and can ensure that the safety boots will not be touched when the aircraft door is opened.
[0009] Furthermore, the safety boots or safety boot assemblies are fixed on the floor of the reception platform within the effective range of the aircraft cabin door of the jet bridge, and the parts of the safety boots or safety boot assemblies that do not need to be in contact with the work are shielded by a multi-section telescopic protective cover, so that the safety boots or safety boot assemblies can work normally while protecting the safety boots or safety boot assemblies from being touched.
[0010] Furthermore, the electric reciprocating telescopic rod device is arranged on the top of the multi-section telescopic protective cover, or is installed on the side of the multi-section telescopic protective cover.
[0011] Furthermore, a rotating shaft is installed on the base, and the rotating shaft is connected to a rotating motor. Driving the rotating motor can rotate the safety boots or the safety boot assembly around the rotating shaft by a certain angle, so that cabin doors of different models can be within the working range of the safety boots.
[0012] Furthermore, the base is provided with a slide rail and a slide groove of a multi-section telescopic protective cover, and the slide groove is provided with rolling steel balls or rollers to reduce the movement resistance of the slide rail.
[0013] Furthermore, the multi-section telescopic protective cover has an appearance of a polygonal folded high-strength door shape, with a retractable multi-section sleeve, and the multi-section telescopic protective cover is a multi-section telescopic structure, and its size is larger than the outline size of the safety boots or safety boot components.
[0014] Furthermore, the safety boot assembly includes a first diffuse reflection matrix fiber optic sensor, a second micro-touch switch and a second diffuse reflection matrix fiber optic sensor, which are integrally mounted on a protective device safety boot mounting bracket, and then connected to the corridor bridge floor through a base, and a multi-section telescopic protective cover covers the parts of the safety boot assembly that do not need to be in contact with work, so that the first diffuse reflection matrix fiber optic sensor, the micro-touch switch and the second diffuse reflection matrix fiber optic sensor in the safety boot assembly can work normally.
[0015] Furthermore, a safety buffer pad is installed on the base near the front end of the safety boot assembly to prevent the safety boot from contacting the bottom of the lower edge of the aircraft cabin door once the function of protecting the aircraft cabin door fails, thereby playing a certain buffering role.
[0016] Furthermore, the safety boot assembly is installed on the upper surface of the corridor bridge pick-up platform through a base, and the laser beam emitted by the safety boot assembly is projected from one side of the corridor bridge pick-up platform operating table to the aircraft cabin door; or the safety boot assembly is installed on the inner platform floor of the anti-collision device (103) where the front edge of the corridor bridge pick-up platform contacts the aircraft, and the measurement distance of the laser beam is controlled within the range of the thickness of all docking cabin doors, but not exceeding the thickness of the thickest cabin door, so as to avoid the laser beam being projected too long onto other objects or body parts of the staff on the corridor bridge pick-up platform and causing malfunction. The laser beam emitted by the safety boot assembly is projected from one side of the fuselage to the inner side of the corridor bridge pick-up platform.
[0017] The technical effects of the present invention are:
[0018] First, the present invention provides a safety boots protection device. Through the multi-section telescopic protective cover and its components, the safety boots can be effectively protected during operation to prevent safety problems caused by the safety boots being touched. At the same time, the present invention provides a safety boots assembly, which is provided with a first diffuse reflection matrix optical fiber sensor, a second micro-touch switch and a second diffuse reflection matrix optical fiber sensor. The assembly is integrally mounted on the safety boots mounting bracket of the protective device, and then connected to the corridor floor through a base. At the same time, a safety buffer cushion is installed on the base 2 near the front end of the safety boots, the purpose of which is to prevent the safety boots from contacting the bottom of the lower edge of the aircraft cabin door once the function of protecting the aircraft cabin door fails, and to play a certain buffering role. In addition, the present invention realizes two installation methods of the safety boots assembly. The safety boots assembly is installed on the upper surface of the corridor pick-up platform through the base, and the laser beam emitted by the safety boots assembly is projected from one side of the corridor pick-up platform to the aircraft cabin door; or the safety boots assembly is installed on the inner side of the front edge anti-collision device of the corridor pick-up platform at the front edge of the pick-up platform, and the laser beam emitted by the safety boots assembly is projected from one side of the fuselage to the inner side of the corridor pick-up platform. In particular, the installation position of the safety boots and protective devices is on the inside of the anti-collision device at the front edge of the receiving platform, which makes full use of the safety distance between the open door and the fuselage of the aircraft. The device is set lower than the height of the bottom of the lower edge of the door when the door is normally opened, but at the same time it can ensure that the safety limit height of its detection is consistent with the height of the existing safety boots detection touch, and the measurement distance of the laser beam is controlled within the range of the thickness of all docking doors, but not exceeding the thickness of the thickest door, so as to avoid the laser beam being projected too long onto other objects or body parts of the staff on the bridge receiving platform and causing malfunction. This setting method will not touch the aircraft when docking, which is a breakthrough in the existing installation method. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.
[0028] Example 1
[0029] See attached Figure 1-3 The safety boots 1 of the safety boots control and protection device of the present invention are installed on a base 2, one end of a steel structure multi-section telescopic safety shield 5 is fixedly installed on the base 2, the other end of the steel structure multi-section telescopic safety shield 5 is connected to one end of an electric reciprocating telescopic rod device 10 for driving the shield through a shield connecting seat 3, and the other end of the electric reciprocating telescopic rod device 10 for driving the shield is fixed on the base 2. In this way, when the telescopic rod of the electric reciprocating telescopic rod device 10 is extended and retracted, the multi-section telescopic shield 5 is driven to move telescopically. A cross laser 6, a first micro-touch switch 7, a laser rangefinder 8, and an acoustic and visual alarm device 4 are installed at the front end of the upper part of the multi-section telescopic protective cover 5, wherein the cross laser 6 is used as an indicator mark when the corridor bridge docks with the bottom edge of the aircraft cabin door and the left edge of the aircraft cabin door, the first micro-touch switch 7 is used for safety redundancy control during the telescopic movement of the multi-section telescopic protective cover 5, and the laser rangefinder 8 is used as a detection device to detect the distance between the multi-section telescopic protective cover 5 and the aircraft cabin door in real time when the multi-section telescopic protective cover 5 is telescopically moved, and feedback is given to the control system of the multi-section telescopic protective cover 5, so that the multi-section telescopic protective cover 5 is telescopically moved at a safe working distance. The acoustic and visual alarm device 4 is used to warn external personnel to pay attention to the fact that this safety boot is in working state and must not be touched or approached. When the multi-section telescopic protective cover 5 starts to work, its acoustic and visual alarm device 4 works at the same time to emit an acoustic and visual warning.
[0030] Based on the above description, the present invention has a cross-shaped laser indicator device that can display the height difference between the lower edge of the cabin door and the floor of the aircraft receiving platform. The device is a cross laser instrument 6. Its function is that when the aircraft is docked, the infrared identification line emitted by the cross laser instrument 6 hits the aircraft fuselage, which can be aligned with the lower edge of the aircraft cabin door and the left side contour of the cabin door. At the same time, it also displays the original set safety distance height difference between the corridor receiving floor and the lower edge of the aircraft cabin door, which can make the safety boots 1 within the effective use range and ensure that the safety boots 1 will not be touched when the aircraft cabin door is opened. The laser measurement cursor of the cross laser instrument 6 is displayed on the aircraft fuselage cabin door area, which is a cross-shaped or a strip-shaped detection area. When it is detected that it is within the set effective safety area range, it is a cross-shaped or a strip-shaped detection area on the aircraft fuselage or cabin door. When it is detected that it is within the set effective safety area range, its indicator light is green. If it is detected that it is outside the set effective safety area, the height of the corridor bridge pick-up platform will be adjusted up, down, left and right according to the set range. At the same time, the indicator light will flash red or yellow until it moves into the safe range. The movement of the pick-up platform will stop and the indicator light will turn green.
[0031] Based on the above description, the present invention is provided with a safety distance detection device composed of a laser rangefinder 8 and a first micro-touch switch 7, and its function is that when the cabin door is opened, the laser rangefinder 8 can automatically detect the safety distance between the cabin door and the multi-section telescopic protective cover 5 as a safety protection device. At the same time, according to the safe position of the aircraft cabin door and the protection range of the safety boots 1, the laser rangefinder 8 automatically feeds back the detected safety protection distance to the control circuit of the multi-section telescopic protective cover 5, and telescopically moves the multi-section telescopic protective cover 5 to the safe range, and at the same time, it will not affect the normal use of the safety boots 1 in the protection area. In order to safely and reliably control the effectiveness of the multi-section telescopic protective cover 5, redundant dual protection of the laser rangefinder 8 and the first micro-touch switch 7 is adopted. When the laser rangefinder 8 fails, it can be detected by the first micro-touch switch 7. When the touch provided at the front end of the first micro-touch switch 7 touches the aircraft cabin door, a feedback control signal is sent, so that the multi-section telescopic protective cover 5 can be effectively prevented from exceeding the safe distance between the aircraft cabin door and touching the cabin door during the movement, causing damage to the aircraft.
[0032] The present invention fixes the safety boots 1 on the floor of the receiving platform within the effective range of the aircraft cabin door of the corridor bridge, and shields the parts of the safety boots 1 that do not need to be in contact with the work by the multi-section telescopic protective cover 5, so that the safety boots 1 can work normally while protecting the safety boots 1 from being touched. That is, according to the opening and closing positions of the cabin doors of different models, after opening the aircraft cabin door, the safety boots 1 can be within the effective range of normal use, so that the safety boots 1 can play a role in protecting the safety of the aircraft, and the safety boots 1 themselves can be protected from damage, and the safety boots 1 can be used normally.
[0033] The present invention has a device capable of controlling the moving distance of a multi-section telescopic protective cover 5 to prevent external forces from touching the safety boots 1. The structure of the device includes an electric reciprocating telescopic rod device 10, the front end of the top rod of which is connected to a movable protective cover connecting seat 3, and the other end is fixed to the floor of the corridor. The multi-section telescopic protective cover 5 is a steel multi-section telescopic structure, the size of which is larger than the outline size of the safety boots 1. The length of the multi-section protective cover 5 is the length of the protected safety boots 1, which can not only enable the safety boots 1 to work normally, but also protect the safety boots 1 from foreign objects or human contact. The electric reciprocating telescopic rod device 10 is controlled by a motor to drive the multi-section telescopic protective cover 5 to move, thereby protecting the area of the safety boots 1 that does not need to contact the work. The electric reciprocating telescopic rod device 10 that drives the multi-section telescopic protective cover 5 can be installed at the top of the protective cover, or it can be installed on the side of the protective cover, so that the installation space is more compact, and its specific installation position is not limited.
[0034] The telescopic process of the multi-section telescopic protective cover 5 of the present invention is controlled by the control circuit to control the speed of the motor, thereby realizing the controllable movement speed of the electric reciprocating telescopic rod device 10. The control circuit can arbitrarily adjust the speed and distance of the electric reciprocating telescopic rod device 10 according to needs, and can also achieve accurate position control by feeding back the distance of the moving process of the electric reciprocating telescopic rod device 10 to the control circuit.
[0035] The multi-section telescopic protective cover 5 of the present invention is provided with a baffle at the front end of one side close to the corridor passage, and the baffle can be lower than the height of the safety boots, so that the multi-section telescopic protective cover 5 can not only protect the upper part of the working area of the safety boots 1, but also protect the side of the safety boots 1 through the baffle, thereby comprehensively covering all areas of the safety boots 1 that need to be protected.
[0036] The safety boots 1 are installed on the upper surface of the receiving platform of the corridor through the base 2 to reduce the placement or retraction of the safety boots 1, reduce the labor intensity of the operator, and also reduce the safety problems caused by operating errors or wrong placement positions.
[0037] According to the different structures of different corridor bridge receiving platforms, the present invention can install a rotatable shaft 17 on the mounting base 2 of the safety boots, and the rotating shaft 17 is connected to the rotating motor 18. Its purpose is to drive the rotating motor 18 to rotate the safety boots 1 around the rotatable shaft to a certain angle according to the size and range of motion of the cabin doors of different models, thereby ensuring that the cabin doors of different models can be within the working range of the safety boots.
[0038] The present invention provides a slide rail 9 and a slide groove 11 of a multi-section telescopic protective cover 5 on the base 2. The material of the slide rail 9 and the slide groove 11 is an anti-corrosion self-lubricating material. The slide groove 11 may have rolling steel balls and rollers to reduce the movement resistance of the slide rail 9 and improve the reliability of the movement of the multi-section telescopic protective cover 5.
[0039] The multi-section telescopic protective cover 5 of the present invention has a polygonal folding door shape and has a telescopic multi-section cover. A guard plate fixedly connected to the multi-section telescopic protective cover 5 is also provided on the vertical surface of the safety boot 1 on the side of the aircraft cabin door. The purpose of providing the fixed guard plate is to prevent the safety boot 1 on the side of the aircraft cabin door from being touched by foreign objects or humans, thereby causing misoperation of the safety boot 1.
[0040] Example 2
[0041] See attached Figure 4-6 The safety boot assembly of this embodiment is composed of a first diffuse reflection matrix optical fiber sensor 13, a second micro-touch switch 12 and a second diffuse reflection matrix optical fiber sensor 14. It is integrally mounted on a protective device safety boot mounting bracket 16 and then connected to the floor of the corridor through a base 2.
[0042] One end of a multi-section telescopic protective cover 5 of a steel structure is fixedly mounted on the base 2, and the other end of the multi-section telescopic protective cover 5 is connected to one end of an electric reciprocating telescopic rod device 10 driving the multi-section telescopic protective cover 5 through a protective cover connecting seat 3, and the other end of the electric reciprocating telescopic rod device 10 driving the multi-section telescopic protective cover 5 is fixed on the base 2. In this way, when the telescopic rod of the electric reciprocating telescopic rod device 10 is extended and retracted, the multi-section telescopic protective cover 5 is driven to move telescopically. A cross laser 6, a first micro-touch switch 7, a laser rangefinder 8, and an audible and visual alarm device 4 are installed at the front end of the upper part of the multi-section telescopic protective cover 5. The cross laser 6 is used as an indication mark when the corridor bridge docks the bottom of the lower edge of the aircraft cabin door and the left edge of the aircraft cabin door. The first micro-touch switch 7 is used for safety redundancy control during the telescopic movement of the multi-section telescopic protective cover 5. The laser rangefinder 8 is used as a detection device to detect the distance between the multi-section telescopic protective cover 5 and the aircraft cabin door in real time when the multi-section telescopic protective cover 5 is telescopically moved, and feedback is given to the control motor system to make the multi-section telescopic protective cover 5 telescopically move at a safe working distance. The sound and light alarm device 4 is for warning outsiders, prompting to note that the safety boots are in working order and must not be touched. When the multi-section telescopic protective cover 5 starts to work, the sound and light alarm device 4 works simultaneously to send sound and light warnings.
[0043] In this embodiment, a safety cushion 15 is installed on the base 2 near the front end of the safety boot, the purpose of which is to prevent the safety boot from contacting the bottom of the lower edge of the aircraft cabin door once the function of protecting the aircraft cabin door fails, and to play a certain cushioning role.
[0044] Based on the above description, the present invention has a cross-shaped laser indicator device that can display the height difference between the lower edge of the cabin door and the floor of the receiving platform, which is a cross laser instrument 6. Its function is that when the aircraft is docked, the infrared identification line of the cross laser instrument 6 hits the aircraft fuselage, which can be aligned with the lower edge of the aircraft cabin door and the left side contour of the cabin door, and also displays the original set safety distance height difference between the corridor bridge receiving floor and the lower edge of the aircraft cabin door, so that the safety boot assembly can be within the effective use range and can ensure that the safety boot assembly will not be touched when the aircraft cabin door is opened. The cross laser instrument 6 is measured by laser and displayed as a cross-shaped or a strip-shaped detection area on the aircraft fuselage cabin door area. When it is detected that it is within the set effective safety area range, its indicator light is green. If it is detected that it is outside the set effective safety area range, the height of the corridor bridge receiving platform is adjusted up, down, left, and right according to the set range, and the indicator light flashes red or yellow until it moves within a safe range. The movement of the receiving platform can stop and the indicator light is green.
[0045] Based on the above description, the present invention is provided with a safety distance detection device composed of a laser rangefinder 8 and a first micro-touch switch 7, and its function is that when the cabin door is opened, the laser rangefinder 8 can automatically detect the safety distance between the cabin door and the multi-section telescopic protective cover 5 of the safety protection device. At the same time, according to the safe position of the cabin door and the protection range of the safety boot assembly, the laser rangefinder 8 automatically feeds back the detected safety protection distance to the control loop, and moves the multi-section telescopic protective cover 5 to its safety protection range, and at the same time, it will not affect the normal use of the safety boot assembly in the protection area. In order to safely and reliably control the effectiveness of the multi-section telescopic protective cover 5, redundant dual protection of the laser detection sensor 8 and the first micro-touch switch 7 is adopted. When the laser detection sensor 8 fails, it can be detected by the first micro-touch switch 7. When the touch provided at the front end of the first micro-touch switch 7 touches the aircraft cabin door, a feedback control signal is sent, so that the multi-section telescopic protective cover 5 can be effectively prevented from exceeding the safety distance between the aircraft cabin door and touching the cabin door during the movement, causing damage to the aircraft.
[0046] In this embodiment, the safety boot assembly composed of the first diffuse reflection matrix optical fiber sensor 13, the second micro-touch switch 12 and the second diffuse reflection matrix optical fiber sensor 14 is fixed to the base 2 on the floor of the receiving platform within the effective range of the cabin door of the aircraft docking bridge through the protective device safety boot mounting bracket 16, and the multi-section telescopic protective cover 5 covers the part of the safety boot assembly that does not need to be in contact with the work, so that the first diffuse reflection matrix optical fiber sensor 13, the micro-touch switch 12 and the second diffuse reflection matrix optical fiber sensor 14 in the safety boot assembly can work normally. According to the door opening position of different models, after opening the aircraft cabin door, the safety boot assembly can be within the effective range of normal use, so that the safety boot assembly can play a role in protecting the safety of the aircraft, and the safety boot assembly itself can be protected without being damaged, and the safety boot assembly can be used normally.
[0047] The present invention is provided with a device capable of controlling the moving distance of the multi-section telescopic protective cover 5 to prevent external forces from touching the safety boots. The structure is an electric reciprocating telescopic rod device 10. One end of the top rod of the electric reciprocating telescopic rod device 10 is connected to the movable protective cover connecting seat 3, and the other end is fixed on the base 2. The multi-section telescopic protective cover 5 is a steel structure multi-section telescopic protective cover. Its size is larger than the outline size of the safety boot assembly, and its length is the size length of the protected safety boot assembly. It can not only enable the safety boot assembly to work normally, but also protect the safety boot assembly from foreign objects or human contact. The electric reciprocating telescopic rod device 10 is controlled by a motor to move and drive the multi-section telescopic protective cover 5 to move, thereby protecting the area where the safety boot assembly does not need to contact the work. The electric reciprocating telescopic rod device 10 that drives the multi-section telescopic protective cover 5 can be installed at the top of the protective cover, or it can be installed on the side of the protective cover, so that the installation space is more compact, and its specific installation position is not limited.
[0048] The telescopic process of the multi-section telescopic protective cover 5 of the present invention is achieved by controlling the speed of the motor by the control circuit to realize the controllable speed of the electric reciprocating telescopic rod device 10. The control circuit can arbitrarily adjust the speed and distance of the electric reciprocating telescopic rod device 10, and can also achieve accurate position control by feeding back the distance of the moving process of the electric reciprocating telescopic rod device 10 to the control circuit.
[0049] The front end of the multi-section telescopic protective cover 5 of the present invention close to the corridor passage can also be provided with a baffle, so that the multi-section telescopic protective cover 5 can not only protect the upper part of the working area of the safety boot assembly, but also protect the side of the safety boot assembly through the baffle, thereby comprehensively covering all areas of the safety boot assembly that need to be protected.
[0050] The safety shoe assembly is installed on the upper surface of the receiving platform of the gallery bridge through the base 2 to reduce the placement or retraction of the safety shoes, reduce the labor intensity of the operators, and also reduce the false alarm and misoperation of the safety shoes caused by operating errors or incorrect placement.
[0051] According to the different structures of different corridor bridge receiving platforms, the present invention can install a rotating shaft 17 on the mounting base 2 of the safety boot protection device. The rotating shaft 17 is connected to the rotating motor 18. The purpose is to drive the rotating motor 18 to rotate the safety boot assembly around the rotating shaft 17 to a certain angle according to the size and range of motion of the cabin doors of different models, thereby ensuring that the cabin doors of different models can be within the working range of the safety boots.
[0052] The present invention provides a slide rail 9 and a slide groove 11 of a multi-section telescopic protective cover 5 on the base 2. The material of the slide rail 9 and the slide groove 11 is an anti-corrosion self-lubricating material. The slide groove 11 may have rolling steel balls and rollers to reduce the movement resistance of the slide rail 9 and improve the reliability of the movement of the multi-section telescopic protective cover 5.
[0053] The multi-section telescopic protective cover 5 of the present invention has a polygonal folding door shape and has a telescopic multi-section cover. A guard plate fixedly connected to the multi-section telescopic protective cover 5 is also provided on the vertical surface of the safety boot assembly near the aircraft cabin door. The purpose of providing the fixed guard plate is to prevent the safety boot assembly near the aircraft cabin door from being touched by foreign objects or humans, thereby causing misoperation of the safety boot assembly.
[0054] Example 3
[0055] The difference between this embodiment 2 is that the installation position of this embodiment is on the inner side of the anti-collision device at the front edge of the receiving platform. The installation position of the safety boots and protective device is shown in FIG. Figure 7 . According to the law of opening the aircraft cabin door, when the aircraft cabin door is opened, there is still a certain distance between the actually opened cabin door and the aircraft fuselage 101, especially there is a certain safety distance between the bottom of the lower edge of the cabin door and the corridor bridge receiving platform 104. Therefore, the safety boots and protective devices 105 are installed by utilizing this gap to project the laser beam from the side of the fuselage to the inner side of the corridor bridge receiving platform, that is, the laser detection beam is projected to the inner side of the opened aircraft cabin door. In the setting method of this embodiment, the device is still lower than the height of the bottom of the lower edge of the cabin door when the cabin door is normally opened, but at the same time it can ensure that the safety limit height it detects is consistent with the height of the existing safety boots detection touch, so that this setting method will not touch when docking the aircraft. Its working principle is that when the aircraft cabin door blocks the laser beam, the device is adjusted to a safe position through the control system. When the aircraft cabin door no longer blocks the laser beam, the device is adjusted to a predetermined position. The key to this embodiment is to control the measurement distance of the laser beam to be within the range of the thickness of all cabin doors, but not exceeding the thickness of the thickest cabin door, so as to avoid the laser beam being projected too long onto other objects on the corridor bridge reception platform or body parts of the staff and causing malfunction.
[0056] For safety and reliability, this embodiment adopts redundant control, and sets 2 laser detectors and 2 mechanical micro switches at one detection height. During the working process, no matter which laser detector or mechanical micro switch fails, the other laser detectors and mechanical micro switches can be activated to send signals and corresponding control instructions to complete the follow-up movement of the receiving platform, thereby protecting the aircraft cabin door.
[0057] The technical solution of the present invention has been explained through the above implementation modes. It should be further pointed out that the above implementation modes are only used to connect the technical solution of the present invention, and are not used to limit the protection scope of the present invention. Any obvious adjustments and modifications made to the above solutions that belong to the technical concept of the present invention should also fall within the protection scope of the present invention.
