Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle launch, and specifically to a launch track detection device with a fault troubleshooting function. Background Art

[0002] Unmanned aerial vehicles, referred to as "drones", are unmanned aircraft controlled by radio remote control equipment and self-contained program control devices, or operated completely or intermittently autonomously by on-board computers. Compared with manned aircraft, drones are often more suitable for tasks that are too "dull, dirty or dangerous". Drones can be divided into military and civilian use according to their application areas. In the military, drones are divided into reconnaissance aircraft and target aircraft. In the civilian field, drones and industry applications are the real rigid demand for drones.

[0003] There are many ways for unmanned aerial vehicles to take off, including taxiing, vehicle-mounted, airdropped, hand-thrown, rocket-assisted, and catapult-launched takeoffs. For the takeoff of small drones, catapult-launched takeoffs are mostly used. Catapult-launched takeoffs require the use of a catapult track device. The drone is placed on the catapult track and ejected using the catapult device. The drone takes off using the thrust generated by the ejection. However, the drone ejection track needs to be inspected regularly. If the edge of the ejection track is uneven, the ejection device will shake when moving on the track, thereby affecting the normal ejection takeoff of the drone. Traditional detection devices are usually only used for the detection and troubleshooting of the internal system of the ejection track, and it is difficult to effectively detect the flatness of the internal track. Utility Model Content

[0004] The utility model provides a launch track detection device with a troubleshooting function, which solves the problem in the related art that traditional detection devices usually only detect and troubleshoot the internal system of the launch track and are difficult to effectively detect the flatness of the inside of the track.

[0005] The technical solution of the utility model is as follows: an ejection track detection device with a fault detection function comprises a track body, an ejection device is installed on the upper part of the track body, a detection mechanism is provided on the outer surface of the track body, the detection mechanism comprises a fixed block, a sleeve is embedded in the interior of the fixed block, two slidable hollow rods are arranged inside the sleeve, the inner wall of each hollow rod is fixedly connected with a tension spring, the ends of the two tension springs away from each other are fixedly connected with a pull rod, one end of the two pull rods is fixedly connected with a movable plate, the upper parts of the two movable plates close to each other are fixedly connected with a movable rod, the ends of the two movable rods close to each other are fixedly connected with a frame, and the inner wall of the frame is installed with a rotatable roller Wheel, the outer surface of each hollow rod is fixedly connected with a fixing ring, the outer surface of each fixing ring is fixedly connected with a fixing plate, the side surfaces of the two fixing plates away from each other are fixedly connected with pressure sensors, the lower parts of the side surfaces of the two movable plates close to each other are fixedly connected with impact rods, the ends of the two impact rods close to each other are respectively in contact with the contacts of the two pressure sensors, the bottom surface of each fixed plate is hinged with a linkage plate, the bottom surface of the fixed block is rotatably connected with a threaded rod through a bearing, the outer surface of the threaded rod is threadedly connected with a screw ring that can move up and down, the outer surface of the screw ring is fixedly connected with two movable plates that can push the linkage plate to move, and the bottom ends of the two linkage plates are respectively hinged to the left and right ends of the two movable plates.

[0006] Furthermore, two arc-shaped plates are fixedly connected to the bottom surface of the track body, and two rotating support plates are arranged between the two arc-shaped plates. A socket is opened on the outer surface of each arc-shaped plate, and a plug rod is inserted into the inside of the socket. The staff can adjust the angle of the track body, and then insert the plug rod into the inside of the socket to fix the adjusted track body, so that the ejection track can be adjusted according to the angle of the UAV ejection take-off, thereby avoiding the difficulty of ejection of the UAV due to too low an angle.

[0007] Furthermore, a fixing seat is fixedly connected to the bottom surface of the support plate, and pins are inserted at the four corners of the upper surface of the fixing seat. During use, the staff inserts the pins into the ground or the inside of the base, thereby fixing the fixing seat with the pins, improving the stability of the fixing seat and the support plate, thereby further improving the stability of the ejection track during use, effectively avoiding shaking during the ejection and take-off of the drone, and avoiding affecting the normal ejection and take-off of the drone.

[0008] Furthermore, the front and back sides of the track body are provided with slide grooves, and each slide groove is slidably connected to a slider that can be displaced parallel to the left and right. The ends of the two sliders that are away from each other are fixedly connected to the side surfaces of the two movable plates that are close to each other. When the movable plates move, they can drive the sliders to slide inside the slide grooves, so that the movable plates can move horizontally along the slide grooves, thereby effectively improving the stability of the movable plates during movement, and effectively preventing the movable plates from shaking or swinging during movement, thereby avoiding affecting the normal detection operation of the detection device.

[0009] Furthermore, a swivel is fixedly connected to the bottom end of the threaded rod, and an anti-slip cover is provided on the outer surface of the swivel.

The two movable plates can slide on the outer surfaces of the sliding rods during movement, so that the movable plates can move along the sliding rods, thereby improving the stability of the movable plates during movement and effectively preventing the movable plates from being deflected and stuck during movement.

[0011] Furthermore, the bottom surface of each sliding rod is fixedly connected to a limiting ring, which can limit the moving plates when the two moving plates move on the outer surface of the sliding rod, effectively preventing the moving plates from moving out of the outer surface of the sliding rod during the movement, thereby avoiding affecting the subsequent normal movement operation of the moving plates.

[0012] Furthermore, the left and right side surfaces of the two hollow rods are inlaid with through rings, and the ends of the two pull rods that are away from each other respectively pass through the two through rings and extend to the outside of the through rings, which can effectively reduce the friction between the pull rods and the hollow rods during movement, effectively avoiding wear on the outer surface of the pull rods due to long-term use, thereby effectively avoiding affecting the subsequent normal use of the pull rods due to wear.

[0014] 1. In the utility model, the threaded rod drives the screw ring to drive the two movable plates to move downward, and the hollow rod pushes the roller to adhere to the inner wall of the track of the track body through the pull rod, the movable rod and the frame. When the inner wall of the track is uneven, the protruding block will push the roller, and the roller drives the movable plate to move through the movable rod, and the movable plate drives the impact rod to move. The impact rod reduces the pressure on the pressure sensor, and the pressure value on the pressure sensor changes. The staff marks the concave and convex positions of the inner wall of the track body to troubleshoot, and the overall uneven position of the ejection track surface can be discovered in time, and the detection mechanism can be adjusted and fixed according to ejection tracks of different sizes.

DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] like Figure 1 to Figure 4 As shown, this embodiment proposes a track body 1, and an ejection device 5 is installed on the upper part of the track body 1.

[0024] The upper surface of the ejection device 5 is provided with different ejection brackets for installing different UAVs.

[0025] A detection mechanism 2 is provided on the outer surface of the track body 1, and the detection mechanism 2 includes a fixed block 201, and a sleeve 208 is embedded inside the fixed block 201. Two slidable hollow rods 205 are provided inside the sleeve 208. The inner wall of each hollow rod 205 is fixedly connected with a tension spring 2019, and the ends of the two tension springs 2019 that are away from each other are fixedly connected with a pull rod 2013, and one end of the two pull rods 2013 is fixedly connected with a movable plate 203, and the upper parts of the two movable plates 203 that are close to each other are fixedly connected with a movable rod 2015.

[0026] The ends of the two movable rods 2015 that are close to each other are fixedly connected to the frame 2016, and the inner wall of the frame 2016 is installed with a rotatable roller 2017. The outer surface of each hollow rod 205 is fixedly connected to the fixing ring 204, and the outer surface of each fixing ring 204 is fixedly connected to the fixing plate 206. The side surfaces of the two fixing plates 206 that are away from each other are fixedly connected to the pressure sensor 2011.

[0027] The lower parts of the two movable plates 203 that are close to one side are fixedly connected with a striker rod 2012, and the ends of the two striker rods 2012 that are close to each other are respectively in contact with the contacts of the two pressure sensors 2011, and the bottom surface of each fixed plate 206 is hinged with a linkage plate 207, and the bottom surface of the fixed block 201 is rotatably connected with a threaded rod 209 through a bearing 202, and the outer surface of the threaded rod 209 is threadedly connected with a screw ring 2010 that can move up and down, and the outer surface of the screw ring 2010 is fixedly connected with two movable plates 2018 that can push the linkage plate 207 to move, and the bottom ends of the two linkage plates 207 are respectively hinged to the left and right ends of the two movable plates 2018.

[0028] The pressure sensor 2011 used in the present application is equipped with a display screen and an alarm. The display screen can display the pressure generated by the impact rod 2012. At the same time, when the pressure value changes, the alarm can sound an alarm in time, so that the staff can find the uneven parts in time.

[0029] Reference Figure 1-2 Two arc plates 6 are fixedly connected to the bottom surface of the track body 1, and two rotating support plates 7 are arranged between the two arc plates 6. The outer surface of each arc plate 6 is provided with a plug hole 11, and a plug rod 10 is inserted into the inside of the plug hole 11.

[0030] The staff can adjust the angle of the track body 1, and then insert the rod 10 into the socket 11 to fix the adjusted track body 1, so that the ejection track can be adjusted according to the ejection angle of the drone, thereby avoiding the difficulty of ejection of the drone due to too low an angle.

[0031] Pins may be inserted at the front and rear ends of the insertion rod 10 , which can effectively prevent the insertion rod 10 from slipping out of the insertion hole 11 during use, thereby avoiding affecting the normal use of the ejection track.

[0032] Reference Figure 1-2 The bottom surface of the support plate 7 is fixedly connected with a fixing seat 8, and four corners of the upper surface of the fixing seat 8 are plugged with pins 9.

[0033] During use, the staff inserts the pins 9 into the ground or the inside of the base, and uses the pins 9 to fix the fixing seat 8, thereby improving the stability of the fixing seat 8 and the support plate 7, thereby further improving the stability of the ejection track during use, effectively avoiding shaking during the ejection and take-off of the drone, and avoiding affecting the normal ejection and take-off of the drone.

[0034] The pins 9 can be replaced with screws according to usage requirements, and the screws can be drilled into a relatively hard base or soil by rotating.

[0035] Reference Figure 1-2 The front and back sides of the track body 1 are provided with slide grooves 3, and each slide groove 3 is slidably connected with a slider 4 that can move parallel to the left and right. The ends of the two sliders 4 that are far away from each other are fixedly connected to the side faces of the two movable plates 203 that are close to each other.

[0036] When the movable plate 203 moves, it can drive the slider 4 to slide inside the slide groove 3, so that the movable plate 203 can move horizontally along the slide groove 3, thereby effectively improving the stability of the movable plate 203 during the movement, and effectively avoiding the shaking or swinging of the movable plate 203 during the movement, thereby avoiding affecting the normal detection operation of the detection device.

[0037] When the detection mechanism 2 is disassembled, the slide block 4 can be taken out from the interior of the slide groove 3 .

[0038] Example 2

[0039] like Figure 3-4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the bottom end of the threaded rod 209 is fixedly connected with a swivel 12, and the outer surface of the swivel 12 is provided with an anti-slip sleeve.

[0040] The staff can rotate the swivel 12 to drive the threaded rod 209 to rotate, which is convenient for rotating the threaded rod 209. At the same time, the protective cover can increase the friction between the hand and the swivel 12 when the staff holds the swivel 12, effectively avoiding hand slippage during rotation.

[0041] At the same time, the anti-slip cover has a certain flexibility, which can effectively increase the comfort of the staff holding the swivel for 12 hours.

[0042] Reference Figure 3-4 Two sliding rods 14 are fixedly connected to the bottom surface of the fixed block 201 , and the bottom ends of the two sliding rods 14 respectively penetrate the two moving plates 2018 and extend to the lower part of the moving plates 2018 .

[0043] During the movement, the two movable plates 2018 can slide on the outer surface of the slide bar 14, so that the movable plates 2018 can move along the slide bar 14, thereby improving the stability of the movable plates 2018 during the movement, and effectively preventing the movable plates 2018 from being deflected and stuck during the movement.

[0044] A ring can be embedded at the position where the slide bar 14 passes through the movable plate 2018, which can effectively reduce the friction between the slide bar 14 and the movable plate 2018 and prevent the slide bar 14 from being worn.

[0045] like Figure 3-4 As shown, the bottom surface of each slide bar 14 is fixedly connected to a limiting ring 13, which can limit the moving plates 2018 when the two moving plates 2018 move on the outer surface of the slide bar 14, effectively preventing the moving plates 2018 from moving out of the outer surface of the slide bar 14 during the movement, thereby avoiding affecting the subsequent normal movement operation of the moving plates 2018.

[0046] like Figure 3-4 As shown, through rings 2014 are embedded on the left and right sides of the two hollow rods 205 , and the ends of the two pull rods 2013 that are away from each other respectively penetrate the two through rings 2014 and extend to the outside of the through rings 2014 .

[0047] The friction between the pull rod 2013 and the hollow rod 205 during movement can be effectively reduced, and the outer surface of the pull rod 2013 can be effectively prevented from being worn due to long-term use, thereby effectively preventing the subsequent normal use of the pull rod 2013 from being affected by wear.

[0048] When in use, first place the two rollers 2017 on both sides of the track body 1, attach the fixed block 201 to the bottom surface of the track body 1, and rotate the threaded rod 209, so that the threaded rod 209 drives the screw ring 2010 to drive the two moving plates 2018 to move downward, and the moving plates 2018 drive the two hollow rods 205 to be retracted into the sleeve 208 through the linkage plate 207. At the same time, the hollow rod 205 pushes the roller 2017 and the track body through the pull rod 2013, the movable rod 2015 and the frame 2016. The inner wall of the track of the track body 1 is attached, and then the staff pushes the detection mechanism 2. When the inner wall of the track is uneven, the protrusion will push the roller 2017, and the roller 2017 drives the movable plate 203 to move through the movable rod 2015, and the movable plate 203 drives the impact rod 2012 to move. The impact rod 2012 reduces the pressure on the pressure sensor 2011, and the pressure value on the pressure sensor 2011 changes. The staff marks the concave and convex positions of the inner wall of the track body 1 to troubleshoot the fault.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
