Description

Technical Field

[0001] This utility model relates to the field of railway engineering, specifically a drone hoisting device for railway engineering construction. Background Technology

[0002] A railway is a track line for trains and other means of transportation. It is a track line formed by laying steel rails. Because railways are laid in the natural environment, track damage often occurs. In order to ensure the safe operation of trains, it is necessary to quickly repair and maintain damaged railway tracks.

[0003] In railway construction, material handling and transfer are necessary. With the development of technology, drone hoisting equipment has been widely used, enabling rapid transportation of materials to the designated location without the need for roads. Existing drone hoisting devices directly lift and transport materials using drones, which is convenient. However, when the drone flies to the railway construction site, there is no good place to park it. Furthermore, if a short-distance transfer is required en route, the drone needs to take off again for hoisting, resulting in poor convenience. Therefore, a new type of drone hoisting device for railway construction is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a drone hoisting device for railway engineering construction, so as to solve the problems mentioned in the background art.

[0024] The drone body 1 lifts the lifting frame 2 through the connecting arm mechanism 3. It can be placed on the railway track 8 by the track wheel 7. At the same time, the track wheel 7 can rotate with the cooperation of the wheel seat 5 and the connecting shaft 6, so that the drone lifting device can be moved along the railway track 8.

[0025] The boom mechanism 3 includes a fixed frame 9 fixedly connected to the top surface of the hoisting frame 2. Hinges 10 are symmetrically fixedly connected to both sides of the fixed frame 9. A boom 11 is symmetrically rotatably connected within the hinge 10. The booms 11 are fixedly connected to each other by a connecting rod 12.

[0026] The shaft that rotatably connects the boom 11 to the hinge seat 10 rotates through the hinge seat 10 and is fixedly connected to the end of the hinge seat 10. The two gears 13 mesh with each other. The boom 11 is fixedly connected to the shaft, and the two gears 13 mesh with each other. When the boom 11 rotates synchronously, a stable suspension state is directly formed after its end is connected to the landing gear of the UAV body 1.

[0027] The top of the boom 11 is hinged to a first hoop 14, and a second hoop 15 is provided above the first hoop 14. The second hoop 15 and the first hoop 14 are fixedly installed by a first fixing bolt 16. The end of the first fixing bolt 16 is threaded with a nut. The second hoop 15 and the first hoop 14 are provided with round holes for the first fixing bolt 16 to pass through.

[0028] The boom 11 can rotate within the hinge seat 10 and form a linkage through the gear 13, thereby allowing for adjustment of the opening and closing angle. In conjunction with the second hoop 15, the first hoop 14, and the first fixing bolt 16, it can be easily and stably connected to the landing gear of the UAV body 1 with different spacing.

[0029] The extension frame 4 includes an end rail 17. An extension rod 18 is uniformly fixedly connected to one side of the end rail 17 corresponding to the hoisting frame 2. The extension rods 18 on the two extension frames 4 are staggered. The outer sides of both ends of the hoisting frame 2 are fixedly connected to guide grooves 19 for the extension rods 18 to pass through and slide. The guide grooves 19 are threadedly connected to the extension rods 18 on both sides of the top. The guide grooves 19 are provided with threaded holes for the second fixing bolts 20 to be threadedly connected. The second fixing bolts 20 are inserted into the extension rods 18. Adjustment holes 21 are provided at equal intervals on the extension rods 18 for the second fixing bolts 20 to pass through and be inserted.

[0030] The extension rod 18 can slide along the guide groove 19 and be inserted into different adjustment holes 21 with the second fixing bolt 20 to adjust the extension length of the extension rod 18, thereby adjusting the total capacity of the hoisting frame 2 and the extension frame 4.

[0031] The end rail 17 is hollow inside, and a matching sealing rail 22 is provided inside the end rail 17. The sealing rail 22 is fixedly installed to the end rail 17 by a third fixing bolt 23.

[0032] The sealing barrier 22 is assembled and installed inside the end barrier 17 by the third fixing bolt 23, so that the sealing barrier 22 can be easily disassembled, and the end face of the extended frame 4 can be opened appropriately for easy loading and unloading of materials.

[0033] The working principle of this utility model is as follows:

[0034] In use, adjust the opening and closing angle of the boom 11 so that the first hoop 14 corresponds to the landing gear of the drone body 1. Then, fix the second hoop 15 to the first hoop 14 with the first fixing bolt 16, thereby connecting it to the drone body 1. This allows the hoisting frame 2 to be connected to the bottom of the drone body 1 via the connecting arm mechanism 3. Materials can then be placed into the hoisting frame 2 and the extension frame 4. During placement, the second fixing bolt 20 can be loosened, allowing the extension rod 18 to slide with the extension guide groove 19, enabling the end rail 17 to extend outwards for placement. After adjusting the space, the second fixing bolt 20 is inserted into the corresponding adjustment hole 21 to form a fixation. At this time, the third fixing bolt 23 on one side can be removed to disassemble the sealing fence 22, so that the material can be easily loaded. Then the sealing fence 22 is reinstalled. At this time, the UAV body 1 can lift the hoisting frame 2 to the construction position of the railway track 8 and stop on the railway track 8. When it is necessary to move the construction position, the whole device can be moved along the railway track 8 by the track wheels 7, so that the transfer can be achieved without the UAV taking off again.
