Description

Technical Field

[0001] The present invention relates to the technical field of box-type substation installation, and specifically relates to a retractable rope fixing device for box-type substation installation. Background Art

[0002] The box-type substation is commonly known as a box substation. A box substation is a high-voltage switchgear, a distribution transformer, and a low-voltage distribution device. It is a factory prefabricated indoor and outdoor compact distribution equipment arranged according to a certain wiring scheme. That is, functions such as transformer step-down and low-voltage power distribution are organically combined together and installed in a moisture-proof, rust-proof, dust-proof, rat-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, movable steel structure box. It is especially suitable for urban network construction and transformation. It is a brand-new substation that emerged after the civil substation. When installing a box substation, it is necessary to connect a rope to the connection ring on the box body, and then the crane lifts the entire box body through the rope and the connection ring for displacement and installation.

[0003] Most of the connection rings on the box body are fixed to the box body by welding. The connection ring and the box body are an integral whole. When the installation of the box body is completed, the connection ring cannot be disassembled at any time, resulting in the connection ring being exposed to the sun, rain and other external environments for a long time along with the box body, which is likely to cause the connection ring to corrode and rust. At this time, the hardness of the connection ring decreases. When it is necessary to disassemble the box body, the brittle connection ring may not be able to bear the weight of the entire box body, resulting in the connection ring breaking during the lifting process of the box body. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention provides a retractable rope fixing device for box-type substation installation.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a retractable rope fixing device for box-type substation installation, including a box body and a mounting rod. Symmetrically arranged mounting blocks are fixedly connected to the box body. Connecting grooves are respectively opened at the central positions of the mounting blocks. Symmetrically arranged receiving grooves are respectively opened inside the mounting blocks corresponding to the positions of the connecting grooves. First springs are fixedly connected inside the receiving grooves, and limiting blocks are slidably connected inside the receiving grooves.

[0006] Sliding grooves are formed in the installation rods, abutting blocks are slidably connected inside the sliding grooves, installation grooves are formed at the central positions inside the installation rods, symmetrically arranged guide rods are fixedly connected inside the installation grooves, symmetrically arranged connecting rods are slidably connected inside the installation grooves, second springs are fixedly connected between the top and bottom connecting rods at positions corresponding to the guide rods, pressure-bearing blocks are fixedly connected to the connecting rods, moving grooves are formed on the outer walls of the installation rods, symmetrically arranged passing grooves are formed at positions corresponding to the moving grooves on the installation rods, moving rings are slidably connected to the moving grooves, third springs are fixedly connected to one ends of the moving rings, pressing plates are fixedly connected to the moving rings at positions corresponding to the passing grooves, annular grooves are formed on the outer walls of the moving rings, round rods are rotatably connected inside the annular grooves, abutting rods are fixedly connected to the round rods, and connecting rings are fixedly connected to one ends of the installation rods.

[0007] Specifically, the connecting grooves and the accommodating grooves are in a communicating state, the first springs are fixedly connected to the limiting blocks at positions corresponding to the inside of the accommodating grooves, and one outer wall of the limiting blocks is inclined.

[0008] Specifically, symmetrically arranged positioning grooves are formed on the installation blocks at positions corresponding to the connecting grooves, positioning rods are fixedly connected to the installation rods at positions corresponding to the positioning grooves, the positioning rods are slidably connected inside the corresponding positioning grooves, the positioning grooves and the connecting grooves are in a communicating state, and the installation rods are slidably connected inside the connecting grooves.

[0009] Specifically, the installation grooves and the sliding grooves are in a communicating state, the installation grooves and the passing grooves are in a communicating state, and the passing grooves and the moving grooves are in a communicating state.

[0010] Specifically, the connecting rods are specifically in an L-shaped setting, one ends of the connecting rods penetrate through the installation grooves and are located inside the sliding grooves, the connecting rods are fixedly connected to the abutting blocks at positions corresponding to the sliding grooves, and one ends of the guide rods slidably penetrate through the connecting rods and the second springs.

[0013] The beneficial effects of the present invention:

[0014] In the present invention, the connecting ring and the box body are separated into two individuals. When it is necessary to connect the connecting ring and the box body, the mounting rod can be directly pushed into the inside of the mounting block. During the process of the mounting rod sliding into the inside of the mounting block, each component will be interlocked. The interlocking of each component will cause the abutting block to retract into the inside of the sliding groove. When the mounting rod is completely connected to the inside of the mounting block, the limiting block will move into the inside of the sliding groove. At this time, the mounting rod, the mounting block, and the connecting ring are connected to the box body. When it is necessary to disassemble the mounting rod and the connecting ring, the blocking rod can be directly pressed back into the inside of the annular groove. At this time, each component will reset to its original position. The reset abutting block will push the limiting block out of the inside of the sliding groove.

DETAILED DESCRIPTION OF THE INVENTION

[0024] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0025] As Figures 1-7 shown, a retractable rope fixing device for box substation installation according to the present invention includes a box body 1 and a mounting rod 2. Symmetrically arranged mounting blocks 3 are fixedly connected to the box body 1. Connecting grooves 4 are opened at the central positions of the mounting blocks 3. Accommodating grooves 5 are symmetrically arranged at positions corresponding to the connecting grooves 4 inside the mounting blocks 3. First springs 6 are fixedly connected inside the accommodating grooves 5. Limiting blocks 7 are slidably connected inside the accommodating grooves 5;

[0026] Sliding grooves 8 are opened on the mounting rods 2. Abutting blocks 9 are slidably connected inside the sliding grooves 8. Mounting grooves 10 are opened at the central positions inside the mounting rods 2. Guide rods 11 are symmetrically arranged and fixedly connected inside the mounting grooves 10. Connecting rods 12 are symmetrically arranged and slidably connected inside the mounting grooves 10. Second springs 13 are fixedly connected between the top and bottom connecting rods 12 at positions corresponding to the guide rods 11. Pressure-bearing blocks 14 are fixedly connected to the connecting rods 12. Moving grooves 15 are opened on the outer walls of the mounting rods 2. Passing grooves 16 are symmetrically arranged at positions corresponding to the moving grooves 15 on the mounting rods 2. Moving rings 17 are slidably connected to the moving grooves 15. Third springs 18 are fixedly connected to one ends of the moving rings 17. Pressing plates 19 are fixedly connected to the moving rings 17 at positions corresponding to the passing grooves 16. Annular grooves 20 are opened on the outer walls of the moving rings 17. Round rods 21 are rotatably connected inside the annular grooves 20. Abutting rods 22 are fixedly connected to the round rods 21. Connecting rings 23 are fixedly connected to one ends of the mounting rods 2.

[0027] The connecting groove 4 and the receiving groove 5 are in a communicating state. The first springs 6 are fixedly connected to the positions inside the receiving groove 5 corresponding to the limiting blocks 7. One outer wall of each limiting block 7 is inclined. The inclined outer wall of the limiting block 7 is convenient for being squeezed by the mounting rod 2, and the first spring 6 is convenient for driving the limiting block 7 to move back. Symmetrically arranged positioning grooves 24 are formed in the mounting block 3 corresponding to the positions of the connecting grooves 4. Positioning rods 25 are fixedly connected to the mounting rod 2 corresponding to the positions of the positioning grooves 24. The positioning rods 25 are slidably connected inside the corresponding positioning grooves 24. The positioning grooves 24 and the connecting grooves 4 are in a communicating state. The mounting rods 2 are slidably connected inside the connecting grooves 4. The connection between the positioning rod 25 and the positioning groove 24 can position the angle of the mounting rod 2 entering the connecting groove 4, which is convenient for the sliding groove 8 and the limiting block 7 to be butted when the mounting rod 2 is connected to the connecting groove 4. The mounting groove 10 and the sliding groove 8 are in a communicating state. The mounting groove 10 and the passing groove 16 are in a communicating state. The passing groove 16 and the moving groove 15 are in a communicating state. The communication between the mounting groove 10 and the passing groove 16 is convenient for the pressing plate 19 to squeeze the bearing block 14 inside the passing groove 16. The specific shape of the connecting rod 12 is L-shaped. One end of the connecting rod 12 penetrates through the mounting groove 10 and is located inside the sliding groove 8. The connecting rod 12 is fixedly connected to the abutting block 9 corresponding to the position of the sliding groove 8. One end of the guiding rod 11 slidably penetrates through the connecting rod 12 and the second spring 13. The connecting rod 12 is convenient for driving the abutting block 9 to move. One outer wall of the bearing block 14 is inclined. One end of the pressing plate 19 is arc-shaped. The arc-shaped part of the pressing plate 19 is convenient for squeezing the inclined outer wall of the bearing block 14. The third springs 18 are fixedly connected to the inner wall of the moving groove 15. The abutting rods 22 are movably connected inside the annular groove 20. The third spring 18 is convenient for driving the moving ring 17 to move back.

[0028] When in use, when it is necessary to lift and install the box body 1, the abutting rod 22 can be rotated outwards from the inside of the annular groove 20. The abutting rod 22 will drive the round rod 21 to rotate together. The round rod 21 provides support for the rotation of the abutting rod 22. When the abutting rod 22 is rotated out from the inside of the annular groove 20, the positioning rod 25 on the mounting rod 2 can be inserted into the corresponding positioning groove 24, and then the mounting rod 2 is instantaneously forced into the connecting groove 4. The mounting rod 2 will drive the moving ring 17 to move into the connecting groove 4 together. During the process of the mounting rod 2 entering the connecting groove 4, the abutting rod 22 will abut against the outer wall of the mounting block 3. At this time, the mounting rod 2 continues to move into the connecting groove 4, while the abutting rod 22 and the moving ring 17 remain in the same abutting position against the mounting block 3. At this time, due to the continuous movement of the mounting rod 2, the mounting rod 2 will squeeze the third spring 18 against the inner wall of the moving groove 15. At this time, as the mounting rod 2 moves, the third spring 18 continuously contracts, and at the same time, the moving ring 17 will continuously move towards the third spring 18 inside the moving groove 15 in a static state, as Figure 3, at this time, the moving ring 17 will cause the pressing plate 19 to press against the inclined outer wall of the bearing block 14. At this time, both bearing blocks 14 will move toward the center position inside the installation groove 10 under the extrusion. The movement of the bearing blocks 14 will drive the connecting rods 12 to move. The connecting rods 12 will move under the guidance of the guiding rods 11. When the two connecting rods 12 move toward the center of the installation groove 10 at the same time, they will jointly compress and contract the two second springs 13. The movement of the two connecting rods 12 will also drive the abutting blocks 9 to retract into the sliding groove 8. At the same time, the installation rod 2 will also press against the inclined outer wall of the limiting block 7 inside the connecting groove 4. At this time, the limiting block 7 will retract into the accommodating groove 5, and the retraction of the limiting block 7 will compress and contract the first spring 6. When the installation rod 2 is completely connected to the connecting groove 4, the sliding groove 8 on the installation rod 2 will correspond to the limiting block 7, and the abutting block 9 inside the sliding groove 8 has retracted into the sliding groove 8, as Figure 3 , so the limiting block 7 will move into the sliding groove 8 under the reset drive of the first spring 6. At this time, the limiting block 7 is connected to the sliding groove 8, and the installation rod 2 is fixed inside the connecting groove 4. The installation of the remaining installation rods 2 is the same. At this time, the rope can be passed through each connecting ring 23, and the box body 1 can be hoisted and installed by a crane and the rope. After the box body 1 is installed, the installation rods 2 and the connecting rings 23 can be removed and stored. The abutting rod 22 can be pressed down with the help of external tools, so that the abutting rod 22 rotates back into the internal annular groove 20, as Figure 4 , at this time, the third spring 18 will drive the moving ring 17 to reset. The reset of the moving ring 17 will drive the pressing plate 19 to reset. At this time, the bearing block 14 is no longer pressed by the pressing plate 19. The two second springs 13 will jointly drive each connecting rod 12 to reset. The reset of the connecting rod 12 will drive the abutting block 9 back to its original position, and the abutting block 9 will press against the limiting block 7 inside the sliding groove 8. The reset force of the second spring 13 is greater than the reset force of the first spring 6. Therefore, the abutting block 9 will squeeze the limiting block 7 out of the sliding groove 8, and the limiting block 7 will also compress and contract the first spring 6 again. At this time, the abutting block 9 returns to the original position of the sliding groove 8, as Figure 4 , the installation rod 2 can be directly pulled out of the connecting groove 4. The disassembly of the remaining installation rods 2 is the same. The operation is very simple, which provides great convenience for the installation and disassembly of the connecting ring 23, enabling the staff to remove and store the installation rod 2 and the connecting ring 23 after installing the box body 1, preventing the connecting ring 23 from becoming brittle due to external factors, and also improving the safety during the disassembly of the box body 1.
