Background Technology

[0002] The grounding device for the overhead contact line of an electrified railway is a special safety device used to reliably and forcibly connect the high-voltage contact line to the ground during railway power outage maintenance. During electrified railway maintenance work, personnel will use a lifting device to lift the grounding device and attach it to the contact line to ensure reliable grounding of the power outage section and protect personnel safety.

[0003] The existing electrified railway contact wire grounding pole lifters are mostly fixed in angle, making it difficult to adjust the angle of the electrified railway contact wire grounding device. This causes considerable inconvenience to personnel when lifting and connecting the electrified railway contact wire grounding device. Utility Model Content

[0004] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that the existing electrified railway contact wire grounding pole lifters are mostly fixed in angle, making it difficult to adjust the angle of the electrified railway contact wire grounding device, which brings great inconvenience to personnel when lifting and attaching the electrified railway contact wire grounding device.

[0005] To solve the above problems, this utility model provides a lifting device for the grounding pole of the overhead contact line of electrified railway, including a base, and an electric push rod is fixedly connected to the top of the base;

[0006] A mounting base is fixedly connected to the telescopic end of the electric push rod. A plug-in seat is movably inserted into the top of the mounting base. A vertical groove is opened on the surface of the plug-in seat. A plug-in block is movably inserted into the interior of the vertical groove. A limit block is fixedly connected to the bottom of the plug-in block. Several symmetrically distributed limit grooves are opened on the top of the mounting base.

[0007] The connector has an adjustment groove, and an adjustment block is rotatably connected inside the adjustment groove via a connecting shaft. A pair of symmetrically distributed lifting rods are placed against the bottom of the adjustment block, and the bottom ends of the lifting rods are threaded into the connector.

[0008] A vertical tube is fixedly connected to the top of the adjusting block, and a shelf is fixedly connected to the top of the vertical tube.

[0009] As a further improvement of this application, the bottom of the base is fixedly connected with several symmetrically distributed reinforcing cones, and there is a gap between the bottom of the adjusting block and the inner bottom wall of the adjusting groove.

[0010] As a further improvement of this application, the lifting rod is provided with a disassembly ring on its outer fixed sleeve, and the outer side of the disassembly ring is engraved with anti-slip texture.

[0011] As a further improvement of this application, a reinforcing groove is provided on each of the two inner sidewalls of the vertical groove, and a slider is fixedly connected to each of the two sidewalls of the plug-in block.

[0012] As a further improvement of this application, metal blocks are fixedly connected to a pair of sides of the slider, and a magnetic coating is applied to a pair of inner sidewalls of the vertical groove to magnetically connect with the metal blocks.

[0013] As another improvement of this application, a press-to-inflate bladder is fixedly connected to the surface of the vertical tube. The press-to-inflate bladder has an air inlet and an air outlet. A one-way valve is provided in both the air inlet and the air outlet. The air outlet is connected to the vertical tube. The interior of the shelf is hollow. The shelf is connected to the vertical tube. An inflatable plate is fixedly connected to the inner top wall and the inner bottom wall of the shelf. The inflatable plate is connected to the shelf.

[0014] As a further improvement to this application, the side of the inflatable plate abuts against the inner wall of the shelf, and in the initial state, there is a gap between the pair of inflatable plates.

[0015] This application has the following beneficial effects when used:

[0016] 1. Place the network cable grounding rod inside the shelf, then start the electric push rod to adjust the height of the network cable grounding rod. During the lifting process, the plug block can be moved upward to move the limiting block out of the limiting groove. Then, rotate the plug seat horizontally to adjust the angle of the network cable grounding rod in the horizontal direction. After that, rotate a pair of lifting rods to move one of the lifting rods downward, and the other lifting rod pushes the adjusting block and all its mechanisms upward to rotate, thereby adjusting the angle of the network cable grounding rod in the vertical direction. Finally, hang the network cable grounding rod on the contact wire. When using this application, it is convenient for personnel to adjust the angle of the network cable grounding rod in the horizontal and vertical directions, and the operation steps are simple and time-saving, greatly improving the convenience of hanging the network cable grounding rod.

[0017] 2. When in use, after placing the network cable grounding rod inside the shelf, you can manually press the air bladder to expel the gas from the air outlet and into the vertical tube. At the same time, pressing the air bladder will draw air from the air inlet to restore the negative pressure. Then, the gas will enter the shelf and the inflatable plate from the vertical tube in sequence, causing the inflatable plate to inflate and expand, thereby clamping the network cable grounding rod and improving its stability during the lifting process.

Detailed Implementation

[0025] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] First implementation method:

[0027] Figure 1-5 A grounding rod lifter for the overhead contact line of an electrified railway is shown, including a base 1, on the top of which an electric push rod 2 is fixedly connected.

[0028] The telescopic end of the electric push rod 2 is fixedly connected to a mounting base 3. A plug-in seat 4 is movably inserted into the top of the mounting base 3. A vertical groove 5 is opened on the surface of the plug-in seat 4. A plug-in block 6 is movably inserted into the interior of the vertical groove 5. A limit block 7 is fixedly connected to the bottom of the plug-in block 6. A number of symmetrically distributed limit grooves 8 are opened on the top of the mounting base 3.

[0029] The plug-in base 4 is provided with an adjustment groove 9. An adjustment block 10 is rotatably connected inside the adjustment groove 9 via a connecting shaft. A pair of symmetrically distributed lifting rods 11 are placed against the bottom of the adjustment block 10. The bottom end of the lifting rods 11 is threaded into the plug-in base 4.

[0030] The top of the adjusting block 10 is fixedly connected to a vertical tube 12, and the top of the vertical tube 12 is fixedly connected to a shelf 13.

[0031] The bottom of the base 1 is fixedly connected with several symmetrically distributed reinforcing cones 14, and there is a gap between the bottom of the adjusting block 10 and the inner bottom wall of the adjusting groove 9.

[0032] The lifting rod 11 is externally fixed with a disassembly ring, and the disassembly ring is engraved with anti-slip texture.

[0033] The vertical groove 5 has a pair of reinforcing grooves 15 on its inner sidewalls, and the plug block 6 has a pair of sliders 16 fixedly connected to its sidewalls.

[0034] Metal blocks 17 are fixedly connected to a pair of sides of the slider 16. A magnetic coating 18 that is magnetically attracted to the metal blocks 17 is coated on a pair of inner sidewalls of the vertical groove 5. When the plug-in block 6 is moved upward so that the plug-in seat 4 is rotated, the magnetic coating 18 will be magnetically attracted to the metal blocks 17, thereby preventing the plug-in block 6 and the limiting block 7 from obstructing the rotation of the plug-in seat 4 when the plug-in seat 4 is rotated.

[0035] This solution can be implemented. When using it, the network cable grounding rod needs to be placed in the shelf 13. Then, the electric push rod 2 is activated, so that its telescopic end pushes the mounting base 3 and all the mechanisms on it to move upward together, thereby adjusting the height of the network cable grounding rod.

[0036] During the lifting process, the plug-in block 6 can be moved upward to allow the limiting block 7 to move out of the limiting groove 8. Then, the plug-in seat 4 can be rotated horizontally to adjust the angle of the network cable grounding rod in the horizontal direction. After that, a pair of lifting rods 11 can be rotated so that one of the lifting rods 11 moves downward and the other lifting rod 11 pushes the adjusting block 10 and all its mechanisms to rotate upward, thereby adjusting the angle of the network cable grounding rod in the vertical direction. Finally, the network cable grounding rod can be hung on the contact wire.

[0037] In summary, this application allows for easy adjustment of the angle of the network cable grounding rod in both horizontal and vertical directions, and the operation is simple and time-saving, greatly improving the convenience of hanging the network cable grounding rod.

[0038] Second implementation method:

[0039] This embodiment adds the following structure based on the first embodiment, while the rest remains the same as the first embodiment, as detailed below:

[0040] Figure 5The vertical tube 12 is shown to be fixedly connected to a press-in air bladder 19. The press-in air bladder 19 has an air inlet and an air outlet, and each air inlet and air outlet is equipped with a one-way valve. The air outlet is connected to the vertical tube 12. The shelf 13 is hollow inside and is connected to the vertical tube 12. An inflatable plate 20 is fixedly connected to the inner top wall and inner bottom wall of the shelf 13. The inflatable plate 20 is connected to the shelf 13. An exhaust valve is provided on the vertical tube 12. When the inflatable plate 20 is released from its clamping effect on the network cable grounding rod, it is only necessary to open the exhaust valve to release the gas in the vertical tube 12 and the inflatable plate 20, thereby releasing the clamping effect of the inflatable plate 20 on the network cable grounding rod.

[0041] The side of the inflatable plate 20 abuts against the inner wall of the shelf 13, and in the initial state, there is a gap between the pair of inflatable plates 20.

[0042] This solution allows for the following usage: After placing the network cable grounding rod inside the shelf 13, pressure can be manually applied to the inflatable bladder 19 to expel gas from the outlet and into the vertical tube 12. Simultaneously, pressing the inflatable bladder 19 restores the negative pressure by drawing air from the inlet. Gas then flows sequentially from the vertical tube 12 into the shelf 13 and the inflatable plate 20, causing the inflatable plate 20 to inflate (in conjunction with...). Figure 5 As shown in the figure, this clamps the grounding rod of the network cable, improving its stability during the lifting process.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
