Technical Field

[0001] The utility model relates to the technical field of aviation, in particular to a skid-type helicopter ground transfer vehicle. Background Art

[0002] Helicopter ground transfer vehicles are specialized vehicles designed for use at airports, helipads, and maintenance bases. They play a vital role in improving helicopter ground mobility efficiency, reducing manpower requirements, and ensuring aircraft safety. Currently, helicopter ground transfer methods involve installing universal wheels on the bottom of the skid, or on the front of the skid, with a forklift at the rear to adjust the direction of movement.

[0003] However, skid-mounted helicopters cannot be stabilized during ground transport, resulting in damage. Furthermore, the transport process requires multiple personnel, reducing efficiency. Different helicopter models vary significantly in size and weight, making methods like installing universal wheels or using a forklift to adjust the direction unsuitable for diverse models.

One end of the motor is connected to a drive wheel, the outer side of the drive wheel is connected to the track, and the motor is electrically connected to the controller. The transverse connecting plate is connected to a transverse connecting rod, which is equipped with an infrared alignment device. Both the infrared alignment device and the transverse connecting rod face away from the vehicle floor.

[0009] In one possible implementation, a universal bracket includes a concave block mounted at the bottom of a helicopter landing gear, with lugs symmetrically positioned on either side of the concave block.

[0018] (3) Safe and reliable: The design of the clamping mechanism ensures the stability of the helicopter during transportation and avoids damage to the aircraft body. The setting of the shock-absorbing movable wheels can provide additional stability and reduce vibration on uneven ground, protecting the aircraft structure.

[0019] (4) Flexibility: The track design on the guard plate enables the universal control vehicle to move under various ground conditions, increasing the applicability of the transfer vehicle.

[0020] Based on the above analysis, the device can be adjusted to the different specifications of the skid-type helicopter's landing gear and can be operated remotely during transfer, reducing manpower requirements and operations, thereby improving work efficiency. Furthermore, the transfer process can be performed by reducing vibration, thus preventing damage to the aircraft. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The utility model provides a skid-type helicopter ground transfer vehicle, comprising two transverse links 1 disposed at the bottom of the helicopter landing gear. One end of each transverse link 1 is connected to a universal control vehicle 2, and the other end of each transverse link 1 is connected to a universal bracket 3. A vertical link 4 is connected between the universal control vehicles 2 and between the universal brackets 3. A clamping mechanism 5 is provided at the end of the universal bracket 3 away from the vertical link 4, and a shock-absorbing movable wheel 6 is provided at the bottom of the universal bracket 3.

[0032] Specifically, see Figure 1The schematic diagram of the device shows the ends of the transverse link 1 and vertical link 4 connected to the universal control vehicle 2 and universal bracket 3, respectively, forming a rectangular frame. The universal control vehicle 2 provides power to the device, positioning the helicopter's landing gear above the universal bracket 3 and clamping mechanism 5. The universal control vehicle 2 then tows the device and the helicopter, while the shock-absorbing movable wheel 6 moves in conjunction with the universal control vehicle 2 at the other end, completing the helicopter's transport.

[0033] Exemplarily, the universal control vehicle 2 includes a floor panel 21, with guard plates 22 symmetrically disposed on either side of the floor panel 21. Battery boxes 210 are symmetrically disposed on opposite sides of the guard plates 22. Each battery box 210 is provided with a voltage regulator 211 at one end, and a light source 212 is disposed directly above each battery box 210. A plurality of guide rotating columns 213 are arranged in an array between the symmetrically disposed battery boxes 210.

[0034] Specifically, the universal control vehicle 2 has two vertically mounted guard plates 22 on either side of its floor panel 21. Two symmetrically positioned guard plates 22 stand opposite each other on either side of the floor panel 21. Battery compartments 210 are symmetrically positioned on opposite sides of the two guard plates 22, i.e., on the inner side of the universal control vehicle 2. Each battery compartment 210 has a voltage regulator 211 at one end to stabilize the output of the batteries within. Furthermore, batteries are housed within the battery compartments 210 to provide power for the device. These batteries can be storage batteries.

[0035] Specifically, a light source 212, located directly above the battery compartment 210, provides illumination for the omnidirectional control vehicle 2 when operating in confined spaces, facilitating operation. Light source 212 may be an LED. A plurality of guide rotating columns 213 are arranged in a rectangular array symmetrically between the two battery compartments 210. The evenly spaced guide rotating columns 213 are spaced to allow passage of the slide tube on one side of the bottom of a helicopter landing gear.

[0036] For example, a long movable shaft 214 is provided at one end of the vehicle floor 21, and a short movable shaft 215 is provided at the other end of the vehicle floor 21. Elastic members 216 are symmetrically provided at both ends of the short movable shaft 215. One side of the elastic member 216 is connected to the vehicle floor 21, and the other side of the elastic member 216 is connected to a guide flap 217, which moves up and down around the elastic member 216.

[0037] Specifically, the vehicle floor 21 is H-shaped as a whole, and the depth of the recess at one end is smaller than that at the other end. A long movable shaft 214 is provided in the recess at the end with the smaller depth, and a short movable shaft 215 is provided in the recess at the other end. Furthermore, the axial length of the short movable shaft 215 is greater than or equal to the distance between the guide rotating columns 213 arrayed on both sides, ensuring that the landing gear of the helicopter can roll on the short movable shaft 215. Elastic members 216 are provided on both ends of the pin shaft of the short movable shaft 215, and the elastic member 216 can be a rebound hinge. The elastic member 216 is connected to the guide flap 217, so that the guide flap 217 can rotate around the pin shaft of the short movable shaft 215. Furthermore, the width of the guide flap 217 can be the width of the recess of the vehicle floor 21, or less than the width of the recess of the vehicle floor 21, see Figure 2 .

[0038] Exemplarily, motors 23 are symmetrically arranged on opposite sides of the symmetrically arranged guard plates 22. A transverse connecting plate 24 is disposed between the symmetrically arranged guard plates 22. Both the motor 23 and the transverse connecting plate 24 are located near one end of the long movable shaft 214. Tracks 25 are disposed on the other side of the symmetrically arranged guard plates 22, facing away from the battery box 210. One side of the symmetrically arranged guard plates 22 is connected to the vertical link 4 and the controller 26. The transverse connecting plate 24 is connected to the transverse link 1 and is equipped with an infrared alignment device 27. The infrared alignment device 27 and the transverse link 1 both face away from the vehicle floor 21.

[0039] Specifically, motors 23 are symmetrically arranged on guard plates 22 on the inner side of the universal control vehicle 2, and tracks 25 are arranged on the outer side of the guard plates 22. Motors 23 drive tracks 25, i.e., batteries in battery compartment 210 provide power to motors 23, which rotate to drive tracks 25 forward or backward. Motors 23 are electrically connected to controllers 26, which in turn generate operating commands from a remote controller.

[0040] Specifically, a transverse connecting plate 24 is provided at one end of the guard plate 22, and is positioned symmetrically between the guard plates 22. The outer side of the transverse connecting plate 24 is connected to the transverse link 1, and an infrared alignment device 27 is also provided at the connection location. Furthermore, the axis of the transverse link 1 is aligned with the centerline of the transverse connecting plate 24, and the axis of the infrared alignment device 27 is aligned with the axis of the transverse link 1.

[0041] Specifically, the outer side of the guard plate 22 , that is, the same side as the crawler track 25 , is respectively connected to the vertical connecting rod 4 and is provided with a controller 26 , that is, the vertical connecting rod 4 and the controller 26 are respectively on both sides of the universal control vehicle 2 .

[0042] Illustratively, the universal bracket 3 includes a concave block 31 with symmetrically disposed lugs 32 on either side. A lifting mechanism 33 and a vertical connecting rod 4 are connected to the sides of the symmetrically disposed lugs 32, respectively. Both the lifting mechanism 33 and the vertical connecting rod 4 face away from the concave block 31, and the bottom of the lifting mechanism 33 is curved.

[0043] Specifically, the concave block 31 is generally U-shaped or flat-bottomed V-shaped. The top of the concave block 31 is open to allow access for the helicopter's landing gear. Ledges 32 are located on either side of the concave block 31. Lifting mechanisms 33 are located on the sides of the lugs 32 facing away from the concave block 31 and are connected to the vertical connecting rod 4. The bottom of the lifting mechanism 33 is curved and convex. The lifting mechanism 33 can be a connecting rod lift, a linear lift, or a hydraulic lift.

[0044] Exemplarily, a plurality of rollers 34 are arranged between the symmetrically arranged ear plates 32 , and the plurality of rollers 34 are respectively close to the two ends of the concave block 31 , and the two ends of the ear plates 32 are respectively connected to the transverse link 1 and the clamping mechanism 5 .

[0045] Specifically, the roller 34 is located at both ends of the concave block 31, and the two ends of the roller 34 respectively abut the inner side of the ear plate 32, and the roller 34 can rotate around its pin. Figure 3 .

[0046] Exemplarily, the transverse link 1 and the vertical link 4 both include a movable rod 71, one end of which is connected to a ratchet adjustment mechanism 74, a fixed rod 72 is provided with a snap ring 73, and the snap ring 73 is connected to the ratchet adjustment mechanism 74, and the fixed rod 72 and the movable rod 71 are both provided with a connecting plate 75 at one end away from the ratchet adjustment mechanism 74, and the outer sides of the connecting plate 75 are respectively connected to the universal control vehicle 2 and the universal bracket 3.

[0047] Specifically, the transverse link 1 and the vertical link 4 have the same structure, consisting of a movable rod 71, a fixed rod 72, a snap ring 73, a ratchet adjustment mechanism 74, and a connecting plate 75. The movable rod 71 and the fixed rod 72 are sleeved together, and one end of the ratchet adjustment mechanism 74 is connected to one end of the movable rod 71, so that when the ratchet adjustment mechanism 74 is operated, the movable rod 71 can move and retract.

[0048] Exemplarily, the ratchet adjustment mechanism 74 includes a swing rod rotatably connected to the frame, one end of which is provided with a pawl. The pawl is engaged with a linear ratchet, one end of which is connected to the movable rod 71, and the frame is connected to the snap ring 73.

[0049] Specifically, when the ratchet adjustment mechanism 74 is operated, it causes the rocker arm to reciprocate up and down relative to the linear ratchet. The ratchet adjustment mechanism 74 is connected to the retaining ring 73 via a frame, and the retaining ring 73 is connected to the fixed rod 72. Therefore, when the linear ratchet moves, it drives the movable rod 71 to move in the same direction, completing the telescopic movement between the movable rod 71 and the fixed rod 72.

[0050] Exemplarily, the clamping mechanism 5 includes a base 51 connected to the universal bracket 3, a groove is provided above the base 51, a first clamping plate 52 and a second clamping plate 53 are provided inside the groove, and a connecting shaft 54 is provided between the first clamping plate 52 and the second clamping plate 53 and the base 51 respectively.

[0051] Specifically, the first clamping plate 52 and the second clamping plate 53 rotate in the groove of the base 51 through the connecting shaft 54 , and one side of the base 51 is connected to the clamping mechanism 5 .

[0052] Exemplarily, the first clamping plate 52 and the second clamping plate 53 are hingedly connected at one end close to the connecting shaft 54 .

[0053] Specifically, the first clamping plate 52 and the second clamping plate 53 are hinged together at one end of the rotation, so that when the helicopter landing gear falls into the clamping mechanism 5, the sliding tube of the landing gear is pressed into the hinged end and moves into the groove. At this time, the ends of the first clamping plate 52 and the second clamping plate 53 away from the base 51 move together, so that the first clamping plate 52 and the second clamping plate 53 surround the sliding tube of the landing gear. For details, see Figure 5 .

[0054] Exemplarily, the damping movable wheels 6 are respectively arranged below the symmetrically arranged ear plates 32 .

[0055] Specifically, two shock-absorbing movable wheels 6 are provided at the bottom of each universal bracket 3 , and the shock-absorbing movable wheels 6 are all provided below the ear plates 32 .

[0056] Example:

[0057] When transporting a skid-type helicopter, adjust the various components of the transport vehicle in advance. Adjust the transverse link 1 and vertical link 4 according to the specifications of the helicopter landing gear. Operate the ratchet adjustment mechanism 74 to adjust the movable rod 71 and fixed rod 72. By adjusting the ratchet adjustment mechanism 74, the movable rod 71 moves so that the distance between the multiple guide rotating columns 213 of the two universal control vehicles 2 and the concave blocks 31 of the two universal brackets 3 connected by the vertical link 4 is equal to the distance between the two slide tubes of the helicopter landing gear. Press the rocker arm of the ratchet adjustment mechanism 74 to adjust the telescopic length of the movable rod 71 to complete the adjustment of the vertical link 4.

[0058] After completing the adjustment of the vertical links 4 at both ends of the device, further adjust the distance between the transverse links 1 on both sides of the device and the coaxiality of the universal control vehicle 2 and the universal bracket 3 connected to the same transverse link 1. Similarly, operate the ratchet adjustment mechanism 74 to adjust the length of the transverse link 1 according to the specifications of the helicopter landing gear. Next, it is necessary to align the central axis position of the transverse link 1 through the infrared alignment device 27 to ensure that the center line of the multiple array-distributed guide rotating columns 213 and the axis of the transverse link 1 are on the same straight line. Then adjust the position of the universal bracket 3 and the clamping mechanism 5 on the same side, and similarly ensure that the universal bracket 3, the clamping mechanism 5, the transverse link 1 and the universal control vehicle 2 are on the same axis. After the adjustment is completed, adjust the position of the other side in the same way.

[0059] After adjusting the positions of the transfer vehicle components, a remote control command is issued to the controller 26 to activate the universal control vehicle 2. First, one end of the guide flap 217 enters the curved end of the landing gear. Due to the presence of an elastic member 216, the guide flap 217 rotates downward after contacting the curved end of the skid. The universal control vehicle 2 continues to move forward, and the curved end of the landing gear is moved toward the short movable shaft 215 by the sloped guide flap 217. The universal control vehicle 2 continues to move forward, and the curved end of the landing gear and the straight section of the landing gear roll on the short movable shaft 215 and enter between the guide rotating columns 213. The transfer vehicle, towed by the universal control vehicle 2, moves forward under the helicopter landing gear to the long movable shaft 214. After the two symmetrical universal control vehicles 2 simultaneously enter the bottom end of the landing gear and move forward a certain distance, the curved end of the landing gear and the adjacent straight section have entered the universal control vehicle 2 and are above the transverse link 1.

[0060] The gimbaled control vehicle 2 continues to move in the direction opposite the curved end of the landing gear. When the gimbaled bracket 3 of the device moves to the curved end of the sliding landing gear, the landing gear first enters the roller 34 at one end of the lug 32. The landing gear rolls forward on the roller 34 and enters the concave block 31. Due to the overall U- or V-shaped concave block 31, the axis of the landing gear is aligned with the centerline of the concave block 31 after entering the roller 34 at the other end of the lug 32. As the device moves forward, the curved end of the landing gear enters the first and second clamping plates 52, 53 of the clamping mechanism 5. When the landing gear is pressed into the hinged position of the first and second clamping plates 52, 53, they rotate about the connecting axis 54. At this point, the ends of the first and second clamping plates 52, 53 near the connecting axis 54 press into the grooves of the base 51. The other ends of the first and second clamping plates 52, 53 move toward each other, ultimately encircling the sliding tube at the bottom of the landing gear.

[0061] At this time, the bottom of the helicopter landing gear enters the transfer vehicle as a whole, and a command is sent to the controller 26 through remote control to adjust the universal control vehicle 2 to continue moving forward. After the entire device has stably loaded the helicopter onto the vehicle, the loading operation of the helicopter transfer vehicle is completed. Figure 6 .

[0062] After the remote-controlled universal control vehicle 2 arrives at the designated destination, the helicopter needs to be unloaded from the device. First, the arc-shaped end of the lifting mechanism 33 of the universal bracket 3 is lowered toward the ground, and after it touches the ground, it continues to fall toward the ground. When the lifting mechanism 33 falls to a certain height, the height of the landing gear at one end of the universal control vehicle 2 is lower than that of the universal bracket 3. Since the center of gravity of the helicopter is tilted toward one end of the universal control vehicle 2, the landing gear slides toward one end of the universal control vehicle 2. When the landing gear gradually leaves the hinged position of the first clamping plate 52 and the second clamping plate 53, the clamping mechanism 5 returns to an unpressurized state, see Figure 5 , that is, the first and second clamping plates 52 and 53 are open at one end away from the base 51. The remote-controlled universal control vehicle 2 moves toward one end of the arc-shaped end of the landing gear, that is, moves in the opposite direction of the helicopter's sliding. After the helicopter's landing gear is completely separated from the device, the helicopter is unloaded.

[0063] In this embodiment, the universal control vehicle 2 is powered by the batteries in the battery box 210, which are supplied to the motor 23. The voltage regulator 211 maintains a stable output voltage of the batteries in the battery box 210. The motor 23 rotates and drives the tracks 25 to move, thereby moving the universal control vehicle 2.

[0064] In this embodiment, the light source 212 provided on the universal control vehicle 2 provides lighting to facilitate operation under special circumstances of the working environment of the transfer vehicle.

[0065] In this embodiment, the rocker rods of the ratchet adjustment mechanism 74 of the transverse link 1 are arranged toward both sides of the device. This prevents the landing gear of the helicopter from being blocked and unable to move when it moves above the device. Figure 6 shown.

[0066] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0067] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
