Description

Technical Field

[0001] This utility model relates to the field of airport ground maintenance equipment technology, and in particular to an in-situ heating device for aircraft parts. Background Technology

[0002] The applicant operates aircraft maintenance bases in extremely cold regions such as Xinjiang. Due to the low winter temperatures, ground maintenance personnel require the use of heaters to warm the aircraft's mirrors and blades during routine maintenance. The existing heaters consist of a controller, a heating combustion chamber, and a fuel tank. The controller is fixedly connected between the combustion chamber and the fuel tank, and the heaters need to be used in conjunction with a generator. The existing heaters have the following drawbacks under actual operating conditions:

[0003] 1) The carrier for the heater cannot be mounted on the airport towing vehicle, making it troublesome, time-consuming, labor-intensive, and inefficient to transport the generator and fuel heater to a remote aircraft stand.

[0004] 2) Since the controller is fixedly connected between the combustion cylinder and the fuel tank, if the road is bumpy during the process of towing it with a common towing tricycle, the heavy controller and heating combustion cylinder are prone to hitting the fuel tank due to the bumps, which may cause the fuel tank to be damaged and unable to operate normally, or even pose a safety hazard.

[0005] 3) The hot air vents of the heating combustion tube of the existing heater are directional, and can only blow out to the back of the heater. If the aircraft parts that need to be heated are located in different positions, the direction of the heater needs to be frequently adjusted to align with the heating position, which is time-consuming, labor-intensive, inefficient, and frequent movement is not conducive to the stable operation of the heater.

[0006] 4) In the cold winter, if a common towing tricycle is used as a vehicle to transport fuel-fired heaters and generators, the front wheels of the towing tricycle are also in contact with the ground. Due to the extreme cold weather, the failure rate of the front wheel components is high, which leads to increased additional maintenance costs. Frequent replacement of the front wheel components also affects the progress of maintenance work. Utility Model Content

[0007] In view of the shortcomings of the prior art, this utility model provides an in-situ heating device for aircraft parts to overcome the deficiencies in the prior art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An in-situ heating device for aircraft components includes a carrier and a generator, a fuel-fired heater, and an external heat pipe mounted on the carrier; the fuel-fired heater includes a controller, a heating combustion chamber, and a fuel tank, with the controller positioned between the heating combustion chamber and the fuel tank.

[0010] The generator is electrically connected to the controller of the fuel-fired heater, the heating combustion chamber is connected to the oil tank pipeline, and the heating combustion chamber is connected to the external heat-conducting pipe flange;

[0011] The vehicle includes a frame, on which a carriage is mounted, and inside the carriage, a support frame and a raised platform are arranged side by side; the heating combustion cylinder is mounted on the support frame, the generator is mounted on the raised platform, the fuel tank is installed in the space at the bottom of the support frame and the raised platform, and the external heat pipe is installed at the rear of the frame and connected to the hot air inlet of the heating combustion cylinder.

[0012] Furthermore, the rear of the frame is provided with two rear wheels, and the front of the frame is provided with a single front wheel. The front wheel is connected to a towing control assembly provided at the front of the frame. The towing control assembly includes a control box fixedly provided at the front of the frame and a traction rod 61 rotatably provided in the control box. The traction rod 61 is connected to the front wheel as a whole.

[0013] The control box includes a first baffle and a second baffle arranged side by side. A first limiting plate and a second limiting plate are connected between the first baffle and the second baffle. The first limiting plate is connected to the rear end of the first baffle and the second baffle, and the second limiting plate is connected to the front end of the first baffle and the second baffle.

[0014] The bottom corner of the control box is provided with a rotating shaft, which passes laterally through the first baffle and the second baffle. The traction rod is located between the first baffle and the second baffle and is rotatably mounted on the rotating shaft.

[0015] The control box is also provided with a first pin hole and a second pin hole that pass through the first baffle and the second baffle horizontally. The first pin hole is located near the first limiting plate, and the second pin hole is located near the second limiting plate. Limiting pins can be inserted and removed into the first pin hole and the second pin hole.

[0016] Preferably, the towing control assembly further includes a retaining cable, which is arranged around both sides of the tow bar and the control box through several lugs, and the two ends of the retaining cable are fixed to the vehicle frame.

[0017] Preferably, the carriage has a single door on the side near the raised frame; a button port is provided on the cover plate on the side of the carriage near the support frame; a top cover is provided on the top of the carriage; and the rear side of the carriage is without a baffle.

[0018] Preferably, the front end of the control box is also provided with a pair of support feet.

[0019] Preferably, the front wheel is a swivel wheel with a locking function.

[0020] Preferably, the control box is fixed to the vehicle frame by fasteners.

[0021] Preferably, the external heat pipe is a flexible corrugated pipe.

[0022] Preferably, the fuel-fired heater is a Protech heater, model "BGO-70A-19-F".

[0023] Preferably, the generator is a Senju 2800W generator, model "SE2800PRO".

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] 1) This case involves an in-situ heating device for aircraft components, in which a generator, a fuel-fired heater, and an external heat pipe are installed on a vehicle. The heating combustion chamber is mounted on a support frame, the generator is mounted on a raised platform, and the fuel tank is installed in the space at the bottom of the support frame and the raised platform. The external heat pipe is installed at the rear of the vehicle frame and connects to the hot air inlet of the heating combustion chamber. Because the heavy heating combustion chamber of the fuel-fired heater is supported by the support frame, the problem of the bottom fuel tank being easily damaged by bumps under bumpy road conditions is solved, ensuring the safe and stable operation of the fuel-fired heater. At the same time, because a flexible external heat pipe is used to connect to the hot air inlet of the heating combustion chamber, the direction of the fuel-fired heater does not need to be frequently adjusted to be aligned with the heating position, making the heating operation more efficient.

[0026] 2) An in-situ heating device for aircraft parts in this case is equipped with a towing control assembly. The towing control assembly uses a limiting pin in the first pin hole and a first limiting plate to limit the towing rod in an upright position; and uses a limiting pin in the second pin hole and a second limiting plate to limit the rotated towing rod in a horizontal position. This allows the towing rod to be adjusted to a horizontal position when towing is required, ensuring that the front wheel does not contact the ground, thereby reducing the failure rate of front wheel-related components, extending the service life of front wheel-related components, reducing maintenance costs, and improving the progress of airport maintenance operations.

[0027] 3) An in-situ heating device for aircraft accessories in this case is equipped with a retaining steel cable. The retaining steel cable is wrapped around both sides of the towing bar and the control box through lugs, and the two ends of the retaining steel cable are fixed to the frame. When the towing bar or the control box breaks accidentally, the retaining steel cable can flexibly connect the towing control components together to avoid the frame from colliding with important airport facilities during rapid towing and enhance the safety of the towing process.

[0028] 4) The aircraft accessory in this case is a simple in-situ heating device. It only requires starting the generator and then starting the heater with one button to quickly provide a heat source. After use, it can be turned off with one button and automatically cools down to the required temperature and then shuts off.

[0029] 5) The aircraft accessory in-situ heating device of this case is lightweight, safe and reliable during two-wheel towing, and can be converted into a three-wheel push when it arrives at the use position, which is conducive to rapid deployment of operations.

[0030] To provide a clearer understanding of this invention, the preferred embodiments of this invention will be described below in conjunction with the accompanying drawings. Attached Figure Description

[0040] Please also refer to Figure 1-7 This utility model provides an in-situ heating device for aircraft accessories, including a carrier and a generator 1, a fuel-fired heater 2, and an external heat pipe 3 mounted on the carrier. The fuel-fired heater 2 includes a controller, a heating combustion chamber 21, and a fuel tank 22. The controller is located between the heating combustion chamber 21 and the fuel tank 22. The generator 1 is electrically connected to the controller of the fuel-fired heater 2. The heating combustion chamber 21 and the fuel tank 22 are connected by pipelines. The heating combustion chamber 21 is flange-connected to the external heat pipe 3. The carrier includes a frame 4, on which a carriage is mounted. A support frame 41 and a raised frame 42 are arranged side by side in the carriage. The heating combustion chamber 21 is mounted on the support frame 41, the generator 1 is mounted on the raised frame 42, the fuel tank 22 is installed in the space at the bottom of the support frame 41 and the raised frame 42, and the external heat pipe 3 is installed at the rear of the frame 4 and connected to the hot air outlet of the heating combustion chamber 21.

[0041] Since the heating combustion cylinder 21 is supported by the support frame 41, the heating combustion cylinder 21 and the controller will not crush the fuel tank 22 when traveling on bumpy roads, ensuring the stable operation of the fuel-fired heater 2. At the same time, since the external heat pipe 3 of the soft body is connected to the hot air port of the heating combustion cylinder 21, it is not necessary to frequently adjust the direction of the fuel-fired heater 2 to align with the heating position, making the heating operation more efficient.

[0042] Furthermore, a single door 43 is provided on the side of the carriage near the raised frame 42, which facilitates starting the generator 1 after opening the door; a button port 44 is provided on the cover plate on the side of the carriage near the support frame 41, which facilitates the hand to reach into the button port 44 to start and stop the fuel-fired heater 2; the rear side of the carriage is without a baffle, which facilitates the connection of the external heat pipe 3 to the hot air outlet of the heating combustion cylinder 21; the top of the carriage is provided with a top cover, which facilitates the shielding and protection of the heating combustion cylinder 21, generator 1 and fuel tank 22 inside the carriage.

[0043] Furthermore, the rear of the frame 4 is provided with dual rear wheels 45, and the front of the frame 4 is provided with a single front wheel 46, which is connected to a towing control assembly located at the front of the frame 4.

[0044] The towing control assembly includes a control box fixedly mounted at the front end of the frame 4 and a tow bar 61 rotatably mounted inside the control box. The tow bar 61 is connected to the front wheel 46 as a whole, and the control box is fixed to the frame 4 by fasteners.

[0045] The control box includes a first baffle 62 and a second baffle 63 arranged side by side. A first limiting plate 64 and a second limiting plate 65 are connected between the first baffle 62 and the second baffle 63. The first limiting plate 64 is connected to the rear end of the first baffle 62 and the second baffle 63, and the second limiting plate 65 is connected to the front end of the first baffle 62 and the second baffle 63.

[0046] A rotating shaft 66 is provided at the bottom corner of the control box. The rotating shaft 66 passes through the first baffle 62 and the second baffle 63 laterally. The traction rod 61 is located between the first baffle 62 and the second baffle 63 and is rotatably mounted on the rotating shaft 66 through a bearing.

[0047] The control box is also provided with a first pin hole 67 and a second pin hole 68 that pass horizontally through the first baffle 62 and the second baffle 63. The first pin hole 67 is located near the first limiting plate 64, and the second pin hole 68 is located near the second limiting plate 65. Limiting pins can be inserted and removed into the first pin hole 67 and the second pin hole 68. The limiting pin in the first pin hole 67 and the first limiting plate 64 cooperate to limit the traction rod 61 in an upright position. The limiting pin in the second pin hole 68 and the second limiting plate 65 cooperate to limit the rotated traction rod 61 in a flat position.

[0048] Preferably, in this embodiment, the front end of the control box is also provided with a pair of support feet 69. When the towing rod 61 is limited to a horizontal position, the towing vehicle can be kept flat on the ground by touching the ground with the support feet 69.

[0049] Preferably, in this embodiment, the towing control assembly further includes a retaining cable 71. The retaining cable 71 is arranged around both sides of the tow bar 61 and the control box through several lugs 72, and both ends of the retaining cable 71 are fixed to the frame 4. The retaining cable 71 is used to flexibly connect the towing control assembly together in the event of accidental breakage of the tow bar 61 or the control box, thereby preventing the vehicle from colliding with important airport facilities during rapid towing and enhancing the safety of the towing process.

[0050] Preferably, in this embodiment, the front wheel 46 of the towing vehicle is a swivel wheel with a locking function.

[0051] Preferably, in this embodiment, the external heat pipe 3 is a flexible corrugated pipe.

[0053] As a preferred embodiment, the generator used in this embodiment is a Senju 2800W generator, model "SE2800PRO".

[0054] Working principle:

[0055] 1. When the heating equipment on this towing vehicle needs to be transferred, first rotate the tow rod 61 to a flat position, and insert a limiting pin into the second pin hole 68. At this time, the limiting pin in the second pin hole 68 and the second limiting plate 65 cooperate to limit the rotated tow rod 61 to a flat position. At this time, the front wheels 46 of this towing vehicle are off the ground. Then, the tow rod 61 is connected to the airport towing vehicle, and the towing vehicle can tow this towing vehicle, which only has rotating rear wheels, to its destination. Since the front wheels 46 do not contact the ground during towing, the failure rate of the front wheels 46 is reduced.

[0056] 2. When the heating equipment on this towed vehicle needs to be operated in place at the maintenance station, first rotate the tow rod 61 to the upright position, and insert the limiting pin into the first pin hole 67. At this time, the limiting pin in the first pin hole 67 and the first limiting plate 64 cooperate to limit the rotated tow rod 61 to the upright position. At this time, the single front wheel 46 and the double rear wheel 45 of this towed vehicle are in contact with the ground. Maintenance personnel can easily push and pull this towed vehicle to a suitable position, and then start the generator 1 and related components of the fuel-fired heater to carry out maintenance work.

[0057] Compared to existing technologies, the in-situ heating device for aircraft components in this case meets the heating requirements for aircraft components in cold climates by installing a generator, a fuel-powered heater, and an external heat pipe on the vehicle. It has good stability, high safety, and is easy to operate.

[0058] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
