Description

TECHNICAL FIELD

[0001] The application relates to the technical field of installation vehicles, and particularly relates to a constant-speed transmission device installation vehicle for unmanned aerial vehicles. BACKGROUND

[0002] It is known that an unmanned mechanical vehicle is referred to as an unmanned aerial vehicle. The unmanned aerial vehicle is a device that is controlled by using radio remote control equipment and a self-provided program control device, or is completely or intermittently operated by an on-board computer. A constant-speed transmission device refers to a special device that is installed on an aero-engine, transmits power to an aircraft alternator, and converts a variable input rotating speed of the aero-engine into a constant output rotating speed.

[0003] When the constant-speed transmission device is installed on the unmanned aerial vehicle, multiple workers are needed to lift the constant-speed transmission device, then the constant-speed transmission device is transported into a mounting groove of the constant-speed transmission device, and then the spline of the constant-speed transmission device is slowly aligned with the spline groove of the engine gear mechanism, until the spline of the constant-speed transmission device is pushed into the spline groove of the engine gear mechanism, and until the spline is engaged, so that the installation work of the constant-speed transmission device is completed.

[0004] A patent with the name of "aircraft main landing gear installation vehicle" and the publication number CN221163353U and the publication date of June 18, 2024 is disclosed. The patent discloses an aircraft main landing gear installation vehicle, which comprises an installation vehicle body and wheels. The upper middle and left side of the installation vehicle body are respectively fixedly connected with a vehicle frame and a first box body. The inside of the first box body is rotatably connected with a first screw rod through a pair of bearings. The lower outer wall of the first screw rod is provided with an adjusting mechanism. The patent relates to the technical field of landing gear installation. The aircraft main landing gear can be moved to between two groups of rollers. The output shaft of the third motor drives the first umbrella-shaped gear to rotate through the second umbrella-shaped gear. The first umbrella-shaped gear drives the second screw rod to rotate. In this way, the second screw rod cooperates with the sliding groove of the second adjusting arm to drive a pair of vertical plates to move towards each other. The vertical plates drive the rollers to move through the concave plates. In this way, the aircraft main landing gear is tightly fixed. Therefore, the number of operators is relatively small, the cost is relatively low, and the landing gear is not easy to fall off and be damaged even if it is shaken. The use effect is better.

[0005] The prior art has the problems that the weight of the constant speed transmission device is about 40 kg, and the key is to assemble the spline on the shaft into the spline groove, the assembly of the spline and the spline groove not only requires that the central axis strictly coincides, but also requires that the circumferential angle is strictly matched, and because the weight is large, it is often found that the parts have been worn out when the circumferential direction is not aligned, in theory, alignment can be achieved by configuring sensors, but there is no installation space for the sensors in the spline groove, which greatly limits the use of intelligent devices, so the assembly difficulty in the prior art is great, and multiple workers are needed to lift and transport the constant speed transmission device into the installation groove, but because the installation position of the constant speed transmission device is at the lower front end of the engine, the installation space of the constant speed transmission device is small, so multiple workers are crowded together to install the constant speed transmission device, which makes the constant speed transmission device inconvenient to install, and further reduces the installation efficiency of the constant speed transmission device.

DETAILED DESCRIPTION

[0032] In order for those skilled in the art to better understand the technical solutions of the present application, the following will combine the accompanying drawings to further describe the present application. Figure 1 to the accompanying Figure 11 Further detailed description of the present application.

[0033] An embodiment provided by the present application relates to a kind of unmanned plane constant speed transmission device installation car, including bearing seat 1 and bottom plate 2, the top of the bottom plate 2 and the bottom end of bearing seat 1 between by the shears fork component of being capable of lifting is connected, further include conveying unit, the conveying unit includes top plate 3, the top of the bearing seat 1 is provided with two slide rails 4 symmetrically, two the slide rail 4 is symmetrically installed on the top plate 3 of being capable of reciprocating sliding, the top plate 3 is provided with the positioning seat 5 for placing constant speed transmission device.

[0034] Specifically, the unmanned plane is a device controlled by radio remote control equipment and self-provided program control device, the constant speed transmission device refers to a special device installed on an aero-engine to transmit power to an aircraft alternator and change variable input speed of the engine into constant output speed, the installation vehicle is a device for moving the constant speed transmission device, and the installation vehicle comprises a bearing seat 1 and a bottom plate 2, the bottom plate 2 and the bearing seat 1 are connected through a scissor assembly, the scissor assembly can drive the bearing seat 1 to perform lifting operation, the scissor assembly comprises a positioning shaft 6, a flat groove is formed in the bottom plate 2, one end of the flat groove is rotatably provided with the positioning shaft 6, and the other end in the flat groove is slidably provided with a driving round rod 7, a sliding groove is formed in the bottom of the bearing seat 1, an auxiliary shaft 8 is rotatably arranged in the sliding groove and located at the same end of the positioning shaft 6, a driven round rod 9 is slidably arranged at the other end of the sliding groove, the positioning shaft 6 and the driven round rod 9 are connected through two symmetrical square rods 10, the driving round rod 7 and the auxiliary shaft 8 are connected through two symmetrical straight rods 11, and the two straight rods 11 and the two square rods 10 are rotatably connected through a connecting shaft 12; a first driving member 13 is arranged on the bottom plate 2, a driving screw 14 is connected to an output end of the first driving member 13, a driving plate 15 is arranged on the driving round rod 7, and the driving screw 14 and the driving plate 15 are threadedly connected.The bottom plate 2 is provided with a pushing handle which can assist in pushing the bottom plate 2, the top end of the bearing seat 1 is symmetrically provided with two slide rails 4, and the top plate 3 is slidably installed on the two slide rails 4. As known by those skilled in the art, a positioning structure (such as a pin shaft positioning or a step positioning) is arranged between the slide rail 4 and the top plate 3, and the positioning structure can position the top plate 3 on the slide rail 4. This positioning structure is a common knowledge in the art and will not be described in detail. The top plate 3 is provided with a positioning seat 5 for placing a constant speed transmission device. The positioning seat 5 is arranged in a mutually adaptive manner with the constant speed transmission device, so that the positioning seat 5 can perform positioning work on the constant speed transmission device. When it is necessary to install the constant speed transmission device, the worker places the constant speed transmission device on the positioning seat 5, and then starts the first driving member 13 (the first driving member 13 is a device with a positive and negative rotating output end, preferably an electric motor) to drive the driving screw 14 to rotate clockwise. The driving screw 14 and the driving plate 15 are threadedly connected. When the driving screw 14 rotates clockwise, it drives the driving plate 15 and the driving round rod 7 to slide along the track of the flat groove towards the end close to the positioning shaft 6, so that the driving round rod 7 drives the two straight rods 11 and the two square rods 10 to rotate around the connecting shaft 12 as the center, so that the straight rods 11 and the square rods 10 drive the bearing seat 1 to move towards the top end, so that the bearing seat 1 drives the constant speed transmission device to move towards the top end through the top plate 3 and the positioning seat 5. Since the driving screw 14 and the driving plate 15 are engaged with each other, the rotation and lifting of the straight rods 11 and the square rods 10 will not shake, thereby improving the stability of the lifting of the bearing seat 1. Until the constant speed transmission device is lifted to the installation groove position of the constant speed transmission device, then the worker pushes the top plate 3 to slide towards the end of the spline groove close to the engine gear mechanism, so that the top plate 3 slides along the track of the slide rail 4, so that the top plate 3 drives the constant speed transmission device to slide towards the end of the spline groove close to the engine gear mechanism, until the spline on the constant speed transmission device is engaged with the spline groove of the engine gear mechanism. Then the worker fixes and installs the constant speed transmission device through the six special bolts. After the constant speed transmission device is installed, the first driving member 13 is started to drive the driving screw 14 to rotate counterclockwise. When the driving screw 14 rotates counterclockwise, it drives the driving plate 15 and the driving round rod 7 to slide along the track of the flat groove away from the end close to the positioning shaft 6, so that the driving round rod 7 drives the two straight rods 11 and the two square rods 10 to rotate around the connecting shaft 12 as the center, so that the straight rods 11 and the square rods 10 drive the bearing seat 1 to move towards the bottom end, so that the bearing seat 1 performs lowering work, until the bearing seat 1 and the top plate 3 are separated from the constant speed transmission device, thereby realizing the installation work of the constant speed transmission device. Through the supporting work of the bearing seat 1 and the top plate 3 on the constant speed transmission device, the lifting work of the worker is reduced, and through the sliding of the top plate 3 on the slide rail 4, the spline on the constant speed transmission device can be engaged into the spline groove of the engine gear mechanism, thereby improving the installation efficiency of the constant speed transmission device.

[0035] The prior art has the problem that the weight of the constant speed transmission device is about 40 kg, and multiple workers are needed to lift and transport the constant speed transmission device into the installation slot, but the installation space of the constant speed transmission device is small due to the installation position of the constant speed transmission device being at the lower front end of the engine, so that the multiple workers are crowded together when installing the constant speed transmission device, which makes the installation of the constant speed transmission device inconvenient, and thus reduces the installation efficiency of the constant speed transmission device.

[0036] The embodiment has the beneficial effect that when the constant speed transmission device of the unmanned aerial vehicle needs to be installed, the worker places the constant speed transmission device on the positioning seat 5, then lifts the carrier seat 1 and the top plate 3 to the installation slot position of the constant speed transmission device through the scissor assembly, then pushes the top plate 3 to slide on the slide rail 4 of the carrier seat 1 to the end of the spline groove of the engine gear mechanism, until the spline on the constant speed transmission device is engaged with the spline groove of the engine gear mechanism, then installs the constant speed transmission device in the installation slot, and then drives the carrier seat 1 and the top plate 3 to disengage from the constant speed transmission device through the scissor assembly, thereby realizing the installation of the constant speed transmission device. Through the support operation of the carrier seat 1 and the top plate 3 on the constant speed transmission device, the lifting operation of the worker is reduced, and through the sliding of the top plate 3 on the slide rail 4, the spline on the constant speed transmission device can be engaged into the spline groove of the engine gear mechanism, thereby improving the installation efficiency of the constant speed transmission device.

[0037] In another embodiment provided by the application, the bottom plate 2 is uniformly provided with four support columns 16 at the bottom end; two mutually symmetrical support columns 16 form a group, a first support plate 17 is rotatably installed on each of the two support columns 16 on one side of the bottom plate 2, a second support plate 18 is rotatably installed on each of the two support columns 16 on the other side of the bottom plate 2, and the first support plate 17 and the second support plate 18 on the same side of the bottom plate 2 are arranged in abutment with each other; the two second support plates 18 are located at the top of the first support plate 17, a universal wheel 19 is rotatably installed at the bottom end of each of the two first support plates 17 and the two second support plates 18; a bearing round rod 20 is arranged on each of the two first support plates 17, a bearing shaft 21 is arranged on each of the two second support plates 18, a hook plate 22 is rotatably installed on each of the two bearing shafts 21, and the two hook plates 22 are respectively hooked to the corresponding bearing round rods 20; a return plate 23 is arranged on each of the two second support plates 18, and a first elastic member 24 is connected between each of the two return plates 23 and the corresponding hook plate 22; the two hook plates 22 are connected through a switch plate 25.

[0038] Specifically, since the bottom plate 2 and the bearing seat 1 need to be positioned during the lifting operation of the constant speed transmission device, the existing universal wheel 19 is locked by the brake on the universal wheel 19, but the universal wheel 19 will still shake even in the locked state. When the constant speed transmission device is installed and rises, the shaking will affect the meshing of the spline of the constant speed transmission device and the spline groove of the engine, thereby affecting the meshing efficiency and installation efficiency of the spline of the constant speed transmission device and the spline groove of the engine. Therefore, the base needs to be positioned during the lifting operation of the base and the bearing seat 1. When the bottom plate 2 needs to be positioned, the worker rotates the switch plate 25 to drive the hook plate 22 to rotate around the bearing shaft 21. The hook plate 22 is provided with a positioning hook, which is matched with the bearing round rod 20. The hook plate 22 drives the positioning hook to be separated from the bearing round rod 20, so that the bearing round rod 20 no longer provides support force for the hook plate 22. At the same time, during the rotation of the hook plate 22 around the bearing shaft 21, the hook plate 22 compresses the first elastic member 24 (the first elastic member 24 is an elastic member capable of elastic recovery, preferably a spring) to make the first elastic member 24 in a compressed state, until the positioning hook and the bearing round rod 20 are separated from each other. The first elastic member 24 rebounds to drive the hook plate 22 to rotate to a position perpendicular to the second support plate 18. Under the action of the gravity of the bottom plate 2 and the support column 16, the first support plate 17 and the second support plate 18 rotate on the support column 16, so that the first support plate 17 and the second support plate 18 drive the universal wheel 19 to be separated from the ground. The second support plate 18 is located on the top of the first support plate 17, and the bottom of the support column 16 is in contact with the ground. The universal wheel 19 is released at the same time, and the bottom plate 2 is positioned by the support column 16 to prevent the bottom plate 2 and the bearing seat 1 from shaking during lifting, thereby improving the stability of the bearing seat 1 driving the constant speed transmission device to lift. When the bottom plate 2 and the bearing seat 1 need to be moved, the worker steps on the second support plate 18 to drive the first support plate 17 to rotate, so that the first support plate 17 and the second support plate 18 drive the universal wheel 19 to abut against the ground until the hook plate 22 abuts against the bearing round rod 20. Under the abutting action of the bearing round rod 20, the hook plate 22 rotates around the bearing shaft 21. During the rotation of the hook plate 22 around the bearing shaft 21, the hook plate 22 compresses the first elastic member 24 to make the first elastic member 24 in a compressed state, until the positioning hook and the bearing round rod 20 abut against each other. Under the rebounding action of the first elastic member 24, the positioning hook on the hook plate 22 and the bearing round rod 20 abut against each other to be connected, so that the hook plate 22 and the bearing round rod 20 are matched to position and connect the first support plate 17 and the second support plate 18. The universal wheel 19 at the bottom end of the first support plate 17 and the second support plate 18 can drive the bottom plate 2 to move, thereby realizing the convenience of moving the bottom plate 2.

[0039] In still another embodiment of the present application, the top plate 3 is provided with a calibration unit, which comprises a U-shaped plate 26, the end of the top plate 3 is provided with a hollow slot 27, the U-shaped plate 26 is slidingly installed in the hollow slot 27, the inner wall of the hollow slot 27 and the U-shaped plate 26 are connected through a second driving element 28, two third driving elements 29 are symmetrically arranged on the U-shaped plate 26, one mounting bracket 30 is connected to the output end of each of the third driving elements 29, a U-shaped bracket 31 is slidingly arranged on each of the mounting brackets 30, a driving gear 32 is rotatably installed at the middle position of each of the U-shaped brackets 31, an auxiliary circular rod 33 is connected to the bottom end of each of the driving gears 32, two half gears 34 are symmetrically arranged on each of the U-shaped brackets 31 in a rotary fit manner at the side of the driving gear 32, the two half gears 34 arranged on the same U-shaped bracket 31 are meshingly arranged with each other, the part of each of the four half gears 34 without teeth is provided with a square block 35, a triangular telescopic rod 36 is arranged on each of the two square blocks 35 close to the top plate 3, the triangular telescopic rod 36 and the spline profile on the constant speed transmission device are adaptively arranged, a triangular block 37 is arranged on each of the two square blocks 35 away from the top plate 3, and the two triangular blocks 37 are adaptively arranged with the spline groove of the engine.

[0040] Specifically, since the visual distance between the spline on the engine and the spline on the constant speed transmission device is short when they are engaged, and even invisible, it is very difficult for the spline on the constant speed transmission device to engage with the spline groove on the engine. The spline on the constant speed transmission device is very delicate and is easy to be damaged. Once damaged, it will leak oil. In addition, the temperature in the nacelle is high, which is easy to catch fire. Once the spline is damaged, it needs to be replaced, which further increases the installation cost of the constant speed transmission device. Therefore, in order to ensure the accuracy of the engagement of the spline (i.e. the spline on the constant speed transmission device) and the spline groove (i.e. the spline groove on the engine), the spline and the spline groove need to be positioned and engaged. Before the staff pushes the top plate 3 and the positioning seat 5 to drive the constant speed transmission device to move towards the end of the spline groove on the engine, the third driving member 29 (the third driving member 29 is a device with a straight reciprocating output end, preferably a cylinder) is started to drive the mounting frame 30 to move away from the end of the top plate 3. The mounting frame 30 drives the U-shaped frame 31 to move away from the end of the top plate 3. The U-shaped frame 31 drives the triangular block 37 and the triangular telescopic rod 36 to move away from the end of the top plate 3 through the half gear 34 and the block 35. Until the triangular block 37 moves to the position where it engages with the spline groove on the engine, then the second driving member 28 (the second driving member 28 is a device with a straight reciprocating output end, preferably a cylinder) is started to drive the U-shaped plate 26 to move towards the end of the spline groove on the engine. The U-shaped plate 26 drives the triangular block 37 and the triangular telescopic rod 36 to move towards the end of the spline groove on the engine through the third driving member 29 and the U-shaped frame 31. Until the two triangular blocks 37 can be tightly engaged with the spline groove on the engine, then the staff pulls the triangular telescopic rod 36 (the triangular telescopic rod 36 is a curved plate with an acute angle cross section, and the angle of the triangular telescopic rod 36 is engaged with the outer wall profile of the spline on the constant speed transmission device. The inside of the triangular telescopic rod 36 is connected by curved plates with the same shape, similar to the telescopic rod of an umbrella. The difference is that the cross section of the triangular telescopic rod 36 is a curved plate) to stretch, so that the end of the triangular telescopic rod 36 tightly engages with the spline on the constant speed transmission device. Then the staff pushes the top plate 3 and the constant speed transmission device to move towards the end of the spline groove on the engine. The triangular telescopic rod 36 contracts synchronously, and the second driving member 28 also contracts synchronously, so that the triangular block 37 is always tightly engaged in the spline groove on the engine, and the triangular telescopic rod 36 is always located outside the spline on the constant speed transmission device when it contracts. Until the triangular telescopic rod 36 contracts to the end of its contraction stroke, then the staff rotates the auxiliary round rod 33 by 90 degrees to drive the driving gear 32 to rotate by 90 degrees. Since the driving gear 32 and the two half gears 34 are engaged, and the parameters of the two half gears 34 and the driving gear 32 are the same (such as module, pitch circle diameter and pressure angle), the driving gear 32 can drive the two half gears 34 to rotate by 90 degrees,The triangle telescopic rod 36 is separated from the spline on the constant speed transmission device, the triangle block 37 is separated from the spline groove of the engine, then the third driving part 29 drives the mounting frame 30 to move towards the end of the top plate 3, the mounting frame 30 drives the U-shaped frame 31 to move towards the end of the top plate 3, so that the U-shaped frame 31, the triangle block 37 and the triangle telescopic rod 36 do not affect the installation of the constant speed transmission device, the staff pushes the top plate 3 to drive the constant speed transmission device to move towards the spline groove of the engine, the top plate 3 drives the spline on the constant speed transmission device to move linearly along the track of the slide rail 4, thereby improving the probability of the spline on the constant speed transmission device and the spline groove of the engine being engaged with each other, preventing the spline on the constant speed transmission device and the spline groove of the engine from being damaged, and thereby improving the installation efficiency of the constant speed transmission device.

[0041] Preferably, each of the two auxiliary circular rods 33 is provided with a locking rod 38, each of the two locking rods 38 is provided with a locking groove 39, each of the two locking grooves 39 is slidably provided with a clamping rod 40, and each of the two locking grooves 39 and the corresponding clamping rod 40 is connected by a third elastic element 41. The bottom end of each of the two U-shaped frames 31 is provided with an arc-shaped plate 42, and each of the two arc-shaped plates 42 is provided with two concave surfaces, the included angle between the two concave surfaces on the same arc-shaped plate 42 is 90 degrees, and the two concave surfaces on the same arc-shaped plate 42 are arranged in abutment with the corresponding clamping rod 40.

[0042] Specifically, when the auxiliary circular rod 33 does not rotate, the locking rod 38 is located in one of the concave surfaces on the arc-shaped plate 42, so that the clamping rod 40 positions the locking rod 38 and the auxiliary circular rod 33 by abutting the concave surface. As can be appreciated by those skilled in the art, in order to facilitate storage, the auxiliary circular rod 33 can be provided as an extendable rod, which is a common practice in the art and will not be described in detail. When the auxiliary circular rod 33 is rotated by 90 degrees, the auxiliary circular rod 33 drives the locking rod 38 to rotate, and the locking rod 38 drives the clamping rod 40 to rotate from one concave surface to another concave surface. Under the action of the elastic force of the third elastic element 41 (the third elastic element 41 is an element capable of elastic reset, preferably a spring), the clamping rod 40 abuts the concave surface, so that the locking rod 38 and the clamping rod 40 position the auxiliary circular rod 33, preventing the auxiliary circular rod 33 from driving the driving gear 32 to rotate and changing the position of the triangle block 37 and the triangle telescopic rod 36.

[0044] Specifically, when the worker pushes the top plate 3 and the constant speed transmission device to move towards the end of the spline groove close to the engine, the triangular telescopic rod 36 is retracted, and at the same time, the second driving part 28 is retracted, so that the triangular block 37 is always tightly in the spline groove of the engine, and at the same time, the top plate 3 drives the driven block 49 to move towards the end of the spline groove close to the engine, until the telescopic rod is retracted to the end of the retraction stroke, in the process, the driven block 49 and the stop block 51 are tightly against each other, and the position of the stop block 51 is unchanged, so that the driven block 49 slides along the track of the accommodation groove 48, so that the driven block 49 extrudes the second elastic part 52 (the second elastic part 52 is an original part capable of elastic reset, preferably a spring), so that the second elastic part 52 is in a compressed state, and at the same time, the driven block 49 drives the connecting rod 50 to move, and the connecting rod 50 drives the advancing plate 46 to move towards the inside of the top plate 3, since the top surface of the advancing plate 46 is a second wedge surface 47, and the bottom of the limiting plate 44 is a first wedge surface 45, the second wedge surface 47 and the first wedge surface 45 are wedge-shaped matched, so that the advancing plate 46 pushes the limiting plate 44 to move towards the end of the spline on the constant speed transmission device, and those skilled in the art can know that in order to adapt to the spline on the constant speed transmission device, the top of the limiting plate 44 can be provided with an arc-shaped tooth structure matched with the spline on the constant speed transmission device, or the top of the limiting plate 44 can be provided with a flexible rubber structure capable of deforming, the purpose is to adapt to the spline on the constant speed transmission device, so that after the advancing plate 46 moves towards the end of the spline on the constant speed transmission device by a distance, the limiting plate 44 can position the spline on the constant speed transmission device, so that after the triangular telescopic rod 36 is separated from the spline on the constant speed transmission device, the limiting plate 44 can position the spline on the constant speed transmission device, and the spline on the constant speed transmission device will not rotate without the limiting of the triangular telescopic rod 36, thereby improving the stability of the spline on the constant speed transmission device and the spline groove of the engine, and preventing the spline groove of the engine and the spline on the constant speed transmission device from being damaged, and improving the efficiency of the constant speed transmission device installation.
