[0006] Beneficial effects: 1. When the present invention transports the bridge condition inspection UAV in the workshop, the buffer slide bar will only drive the card wheel bearing platform to rotate when it goes down. The buffer slide bar has small downward resistance, which can effectively reduce the longitudinal impact on the bridge inspection UAV when it is placed on the UAV bearing platform, and reduce the impact on the connection parts of some assembled bridge inspection UAVs. At the same time, when the buffer slide bar goes up, it will drive the card wheel bearing platform and the one-way buffer wheel to rotate synchronously, so that the buffer slide bar will only rise slowly, avoiding the secondary impact between the various parts of the bridge inspection UAV caused by the rapid rebound of the buffer slide bar. At the same time, the placement requirements of the operator when placing the bridge inspection UAV are low, and the placement and transportation safety are better.

[0007] 2. When the present invention is used to transport a bridge condition inspection UAV in a workshop, the arc radius of the arc-shaped buffer avoidance groove is the same as the spacing between the lower support shaft avoidance grooves, so that during the downward movement of the movable bearing mounting platform, the adjacent lower support shaft avoidance grooves and the linked sprockets corresponding to the arc-shaped buffer avoidance grooves maintain an unchanged spacing during the relative movement, so that the transmission chain at the corresponding position still maintains effective transmission, so that this device only requires a single motor to maintain the synchronous movement of all the lower load-bearing wheels inside the device, reducing the number of motors required for this device and reducing the production cost of this device. At the same time, the impact force generated when placing the bridge inspection UAV will only be absorbed by the buffer mechanism, and the transmission chain will not be damaged by excessive tension due to the impact, thereby ensuring the stability of the transmission process.

[0008] 3. When the present invention is used to transport a bridge condition inspection UAV in a workshop, the adjusting knob is rotated to drive the adjusting block to drive the screw to rotate, thereby controlling the lateral movement of the position adjustment block, thereby adjusting the depth of the wheel mounting platform positioning slide bar into the wheel mounting platform positioning groove, thereby adjusting the initial position of the bracket side clamping plate and the position after clamping, thereby adapting to the clamping and positioning requirements of different models of bridge inspection UAVs and increasing the processable range of the device.

[0009] 4. The side clamping plate of the bracket of the present invention is connected to the claw bearing block by a spring, and the spring provides a certain supporting force for the side clamping plate of the bracket, so that when the side clamping plate of the bracket just starts to press against the drone bracket, the side clamping plate of the bracket will not produce a large relative movement with the claw bearing block, thereby preventing the longitudinal bracket positioning claw from producing a large displacement. During the continuous operation of the side clamping plate of the bracket, the drone bracket will be gradually straightened by the side clamping plate of the bracket, until the drone bracket is completely straightened and the side clamping plate of the bracket cannot move forward. At this time, the claw bearing block continues to move forward to press the longitudinal bracket positioning claw against the two ends of the drone bracket, thereby realizing the sequential clamping of straightening first, then completing lateral positioning, and finally completing front and rear positioning. There will be no interference between the various positioning components, and the positioning process is stable. The bridge inspection drone that is crooked during placement can still be effectively straightened and fixed, which reduces the requirements for operators when placing the bridge inspection drone, increases the efficiency of placing the bridge inspection drone, and further increases the assembly efficiency of the device.

The three groups of buffer spiral grooves 37 are evenly arranged around the buffer slide bar 27. A spiral groove connecting block 47 is provided inside the buffer rod connecting groove 48. The spiral groove connecting block 47 is adapted to the buffer spiral groove 37. The spiral groove connecting block 47 is connected to the buffer spiral groove 37. The spiral groove connecting block 47 slides inside the buffer spiral groove 37. A one-way driving card wheel 44 is provided at the bottom of the card wheel bearing platform 43. A card column mounting groove 441 is provided on the side of the one-way driving card wheel 44. The card column mounting grooves 441 are evenly arranged around the one-way driving card wheel 44.

A card column receiving groove 44 is provided in the counterclockwise direction of the card column mounting groove 441 when viewed from above. 3. A one-way clamping column 46 is arranged inside the clamping column installation groove 441, and the radius of the one-way clamping column 46 is the same as the radius of the clamping column receiving groove 443. A buffer wheel connecting platform 42 is arranged at the bottom of the buffer bearing block 29, and a one-way buffer wheel 38 is arranged at the bottom of the buffer bearing block 29. A buffer wheel connecting groove 41 is arranged on the top of the one-way buffer wheel 38. The buffer wheel connecting groove 41 is adapted to the buffer wheel connecting platform 42, and the buffer wheel connecting groove 41 is connected to the buffer wheel connecting platform 42.

A clamping wheel installation groove 45 is arranged inside the one-way buffer wheel 38, and the clamping wheel installation groove 45 is adapted to the one-way driving clamping wheel 44. The clamping wheel installation groove 45 is connected to the one-way driving clamping wheel 44, and the clamping wheel installation groove 45 rotates outside the one-way driving clamping wheel 44.

[0029] Furthermore, the conveying mechanism 7 drives all the lower load-bearing wheels 14 to rotate synchronously through the transmission mechanism of the interlocking sprocket 19 and the transmission chain 21. The lower load-bearing wheels 14 rotate while driving the drone bearing platform 6 to continuously move forward. When the operator places the bridge inspection drone 4 on the drone bearing platform 6 at the starting point of the main support frame 1, the drone bracket 5 of the bridge inspection drone 4 contacts the drone bearing platform 6 to produce a longitudinal impact, and the drone bearing platform 6 moves downward, so that the drone bearing platform 6 drives the lower load-bearing wheels 14 at the corresponding position to move downward, thereby causing the dynamic bearing mounting platform 22 at the corresponding position to move downward, causing the buffer slide bar 27 to slide downward in the buffer slide bar mounting groove 86, and causing the spiral groove connecting block 47 to slide in the buffer spiral groove 37, thereby causing the one-way drive card wheel 44 to rotate counterclockwise. The one-way clamping column 46 is inserted into the clamping column receiving groove 443. At this time, the one-way clamping column 46 only contacts the clamping column receiving groove 443, so that the one-way drive clamping wheel 44 can rotate freely inside the one-way buffer wheel 38, so that the buffer slide bar 27 can quickly descend. When the dynamic bearing mounting platform 22 is supported upward by the spring between the buffer rod mounting platform 26 and the buffer mechanism 9, the one-way drive clamping wheel 44 rotates counterclockwise, so that the one-way clamping column 46 is in contact with the clamping column driving inclined surface 442 and the clamping wheel mounting groove 45 at the same time, so that the one-way drive clamping wheel 44 and the one-way buffer wheel 38 move synchronously. The one-way buffer wheel 38 has a large mass, and the friction between the buffer wheel connecting groove 41 and the buffer wheel connecting platform 42 is large, so that the buffer slide bar 27 will only slowly ascend when it rises until the drone carrier platform 6 resets and ascends to the limit position.

[0030] It should be noted that when the bridge condition inspection UAV is transported in the workshop, the buffer slide bar 27 will only drive the card wheel bearing platform 43 to rotate when it goes down. The buffer slide bar 27 has a small downward resistance, which can effectively reduce the longitudinal impact on the bridge inspection UAV 4 when it is placed on the UAV bearing platform 6, and reduce the impact on the connection parts of the partially assembled bridge inspection UAV 4. At the same time, when the buffer slide bar 27 goes up, it will drive the card wheel bearing platform 43 and the one-way buffer wheel 38 to rotate synchronously, so that the buffer slide bar 27 will only rise slowly, avoiding the rapid rebound of the buffer slide bar 27 causing secondary impact between the various parts of the bridge inspection UAV 4. At the same time, the operator has low placement requirements when placing the bridge inspection UAV 4, and the placement and transportation safety are better.

[0031] It should be noted that when the bridge condition inspection UAV is transported in the workshop, the arc radius of the arc-shaped buffer avoidance groove 84 is the same as the spacing between the lower support shaft avoidance groove 83, so that the adjacent lower support shaft avoidance groove 83 and the arc-shaped buffer avoidance groove 84 The interlocking sprocket 19 corresponding to the groove maintains an unchanged spacing during the relative movement process during the downward movement of the movable bearing mounting platform 22, so that the transmission chain 21 at the corresponding position still maintains effective transmission, so that this device only needs a single motor to maintain the synchronous movement of all the lower load-bearing wheels 14 inside this device, reducing the number of motors required for this device and reducing the production cost of this device. At the same time, the impact force generated when placing the bridge inspection UAV 4 will only be absorbed by the buffer mechanism 9, and the transmission chain 21 will not be damaged by excessive tension due to the impact, thereby ensuring the stability of the transmission process.

The bottom of the wheel mounting platform positioning slide bar 72 is provided with a driven wheel mounting platform 68, and the top of the driven wheel mounting platform 68 has a wheel mounting platform positioning plate 69. The wheel mounting platform positioning plate 69 has a wheel mounting platform positioning groove 71 inside, and the wheel mounting platform positioning groove 71 is adapted to the wheel mounting platform positioning slide bar 72. The mounting platform positioning groove 71 is connected to the wheel mounting platform positioning slide bar 72, and the wheel mounting platform positioning groove 71 slides on the outside of the wheel mounting platform positioning slide bar 72. The position adjustment block 77 is connected to the wheel mounting platform positioning plate 69 by a spring. The driven wheel mounting platform 68 has a driven wheel mounting shaft 73 inside, and the driven wheel mounting shaft 73 is rotatably connected to the driven wheel 74. The driven wheel 74 at the starting point of the main support frame 1 contacts the inner wall of the main support frame 1, and the main support frame 1 has a clamping guide platform 3 inside. The driven wheel 74 that is not at the starting point of the main support frame 1 is pressed against the side of the clamping guide platform 3.

[0034] An operating method for a drone assembly device for bridge condition detection includes the following steps: In the first step, a staff member places a to-be-assembled bridge detection drone 4 on a drone carrier platform 6 at an initial position. As the drone carrier platform 6 moves forward, when the clamping positioning mechanism 8 contacts the clamping guide platform 3, the clamping positioning mechanism 8 gradually straightens the to-be-assembled bridge detection drone 4 and clamps it on the side of the drone bracket 5, thereby completing the positioning of the to-be-assembled bridge detection drone 4. After the positioned to-be-assembled bridge detection drone 4 completes the subsequent assembly operation, in the second step, the clamping positioning mechanism 8 is disconnected from the clamping guide platform 3, the clamping positioning mechanism 8 no longer provides positioning for the bridge detection drone, and the assembled bridge detection drone can be removed.

[0035] Furthermore, when the bridge condition inspection drone is transported in the workshop, as the drone carrying platform 6 continues to move forward from the starting point, the driven wheel 74 gradually moves from contact with the inner wall of the main support frame 1 to contact with the side of the clamping guide platform 3. During this process, the two bracket side clamps 52 connected to the drone carrying platform 6 are gradually pressed toward the side of the drone bracket 5 until they contact the drone bracket 5, thereby straightening the bridge inspection drone 4. After the bracket side clamps 52 are completely in contact with the drone bracket 5, the claw bearing block 35 continues to press toward the drone bracket 5. At this time, the spring between the claw bearing block 35 and the bracket side clamps 52 is compressed and contracted, so that the bracket side clamps 52 are pressed against the side of the drone bracket 5, and the horizontal hydraulic cylinder connecting rod 53 slides into the inside of the horizontal hydraulic cylinder 51. The hydraulic oil inside the horizontal hydraulic cylinder 51 is pressed into the inside of the longitudinal hydraulic cylinder 56, so that the longitudinal bracket positioning claws 62 on both sides gradually approach each other until the longitudinal bracket positioning claws 62 are pressed against the two ends of the drone bracket 5, thereby completing the clamping and positioning of the bridge inspection drone 4.

[0036] It should be noted that by rotating the adjusting knob 67 to drive the adjusting block to drive the screw 78 to rotate, the position adjusting block 77 is controlled to move horizontally, thereby adjusting the depth of the wheel mounting platform positioning slide 72 into the wheel mounting platform positioning groove 71, thereby adjusting the initial position of the bracket side clamp 52 and the position after clamping is completed, so as to adapt to the clamping and positioning requirements of different models of bridge inspection drones 4 and increase the processable range of this device.

[0037] It should be noted that the bracket side clamping plate 52 is connected to the claw bearing block 35 by a spring, and this spring provides a certain supporting force for the bracket side clamping plate 52, so that when the bracket side clamping plate 52 just starts to press against the drone bracket 5, the bracket side clamping plate 52 will not produce a large relative movement with the claw bearing block 35, so that the longitudinal bracket positioning claw 62 will not produce a large displacement. During the continued operation of the bracket side clamping plate 52, the drone bracket 5 will be gradually straightened by the bracket side clamping plate 52 until the drone bracket 5 is completely straightened. After the bracket side clamping plate 52 cannot move forward, at this time, the claw bearing block 35 continues to move forward to press the longitudinal bracket positioning claw 62 against the two ends of the drone bracket 5, thereby realizing the sequence of straightening first, then completing lateral positioning, and finally completing front and rear positioning. There will be no interference between the various positioning components, and the positioning process is stable. The bridge inspection drone 4 that is crooked during placement can still be effectively straightened and fixed, which reduces the requirements for operators to place the bridge inspection drone 4, increases the efficiency of placing the bridge inspection drone 4, and further increases the assembly efficiency of this device.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
