Description

Technical Field

[0001] The present invention relates to the technical field of safety equipment, and particularly relates to a safety rope mechanism for installing a main transformer. Background Art

[0002] The main transformer, abbreviated as the main transformer, is the main step-down transformer mainly used for power transmission and transformation in a unit or substation, and is also the core part of the substation. It is the core equipment of the electric locomotive traction power supply system and plays a key role in ensuring the safe and stable operation of the traction power supply system. During the installation of the main transformer, workers may need to perform delicate operations at heights. The presence of safety ropes can effectively prevent them from falling due to accidental slips or loss of balance, and can provide double protection for the workers during the installation of the main transformer, ensuring their personal safety during high-altitude operations.

[0003] Since the main components above the top of the transformer during installation include insulating bushings, oil conservators, tap changers, and thermometers, hanging safety ropes may exert unnecessary pressure or tension on them, thus affecting their performance. Therefore, there is no suitable position on the top of the transformer to hang safety ropes. Most personnel at the operation sites do not take anti-falling measures or use safety belts in a low-hanging and high-using manner for operations, posing a risk of workers falling during operations and causing personal injuries. Therefore, a safety rope mechanism for installing a main transformer is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the defect that there is no suitable position on the top of the transformer to hang a safety rope in the prior art, and to propose a safety rope mechanism for installing a main transformer.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0006] A safety rope mechanism for installing a main transformer, including a support plate, a safety rope, a main transformer, a bottom plate, and a support column. An expansion rod is installed on the upper part of the support plate, and a connecting hook is rotatably connected to the upper part of the expansion rod. A first connection component is arranged on the support plate. The first connection component includes first fixing plates symmetrically and slidably arranged at the bottom of the support plate, a plurality of telescopic plates slidably arranged on the sides of the first fixing plates, and a second fixing plate movably connected to the bottom of the support plate. A first threaded rod is rotatably connected to the upper part of the second fixing plate, and the first threaded rod is threadedly connected to the support plate. The two first fixing plates can clamp the bottom plate by moving towards each other. When the first fixing plates clamp the bottom plate, the telescopic plates contract, and the telescopic plates not in contact with the bottom plate limit the bottom plate. Rotating the first threaded rod drives the second fixing plate to move downward and abut against the bottom plate;

[0007] A second connection assembly is provided on the support plate. The second connection assembly includes a limiting plate slidably arranged on the side of the telescopic rod, a rotating ring rotatably connected to the side of the support plate, a first fixing rope and a second fixing rope respectively installed on the outer side of the rotating ring, a first fixing block installed at the end of the first fixing rope, and a second fixing block installed at the end of the second fixing rope. The second fixing block and the first fixing block are connected in a snap-fastening manner. A worm gear is installed at the end of the rotating ring, and a worm is rotatably connected to the side of the support plate. The worm is meshed with the worm gear. When the two first fixing plates and the second fixing plate clamp the support column, move the limiting plate until the limiting plate abuts against the support column, and then connect the second fixing block and the first fixing block. Rotate the worm and drive the rotating ring to rotate through the worm gear. When the rotating ring rotates, it tightens the support column by pulling the first fixing rope and the second fixing rope, which can provide a stable hanging point for the safety rope of the staff and ensure safety during work.

[0008] The above technical solution further includes:

[0009] A first sliding groove is formed at the bottom of the support plate. First sliding blocks are symmetrically and slidably arranged inside the first sliding groove. The side of the first sliding block away from the telescopic rod is fixedly connected to the first fixing plate. A bidirectional threaded rod is rotatably connected inside the first sliding groove. The bidirectional threaded rod is threadedly connected to the first sliding block. When the bidirectional threaded rod rotates, the acting force generated drives the two first sliding blocks to move towards each other along the first sliding groove.

[0010] A plurality of first square grooves are formed inside the first fixing plate. The telescopic plate is slidably arranged inside the first fixing plate. A first spring is installed inside the first square groove. The end of the first spring is fixedly connected to the telescopic plate. When the telescopic plate is squeezed by the bottom plate, it retracts into the first square groove.

[0011] A movable rod is installed on the upper part of the second fixing plate. The movable rod is slidably connected to the support plate. The second fixing plate can move through the support of the movable rod.

[0012] A second sliding groove is formed on the side of the telescopic rod. A second sliding block is slidably arranged inside the second sliding groove. A second threaded rod is rotatably connected inside the second sliding groove. The second threaded rod is threadedly connected to the second sliding block. An arc-shaped plate is installed on the side of the second sliding block. One end of the arc-shaped plate away from the second sliding block is fixedly connected to the limiting plate. When the second threaded rod rotates, the acting force generated drives the second sliding block to move along the second sliding groove.

[0013] A rotating rod is rotatably connected inside the telescopic rod. A transmission belt is sleeved jointly on the rotating rod and the second threaded rod. When the rotating rod rotates, it drives the second threaded rod to rotate through the transmission belt.

[0014] A fixing groove is formed in the side surface of the second fixing block, a limiting block is installed on the side surface of the first fixing block, second square grooves are symmetrically formed in the inner side of the fixing groove, a telescopic block is slidably arranged in the inner side of the second square groove, a second spring is installed in the inner side of the second square groove, the end of the second spring is fixedly connected to the telescopic block, a round rod is installed on one side of the telescopic block close to the second spring, the round rod is movably connected to the second fixing block, and the telescopic block is inserted into the groove of the limiting block, so as to lock the limiting block and realize the connection between the first fixing block and the second fixing block.

[0015] The cross section of the telescopic block is trapezoidal, both telescopic blocks are located on the movement track of the limiting block, and the inclined surface of the telescopic block can be squeezed when the limiting block moves, and the size of the opening of the fixing groove is adapted to the size of the limiting block.

[0016] The size of the opening of the groove of the limiting block is adapted to the size of the telescopic block, ensuring the stability of the connection between the first fixing block and the second fixing block.

[0017] A plurality of the telescopic plates are vertically and evenly distributed on the side surface of the first fixing plate, facilitating the limitation of the bottom plate.

[0018] The present invention has the following beneficial effects:

[0019] 1. In the present invention, by arranging the first connection component, the support plate and the connection hook can be installed on the bottom plate, and then the safety rope of the worker can be hung on the connection hook for installation work, which can provide a stable hanging point for the safety rope of the worker and ensure the safety during work.

[0020] 2. In the present invention, by arranging the second connection component, when the bottom plate does not support the installation of the support plate, the support plate can be installed on the support column, increasing the installation scenarios of the support plate.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1

[0032] Such as Figure 1 - Figure 8As shown in the figure, a safety rope mechanism for installing a main transformer proposed by the present invention includes a support plate 1, a safety rope 4, a main transformer 35, a bottom plate 36, and a support column 37. An expansion rod 2 is installed on the upper part of the support plate 1, and a connecting hook 3 is rotatably connected to the upper part of the expansion rod 2. A first connection assembly is arranged on the support plate 1. The first connection assembly includes first fixing plates 7 symmetrically and slidably arranged at the bottom of the support plate 1, a plurality of telescopic plates 10 slidably arranged on the side surfaces of the first fixing plates 7, and a second fixing plate 12 movably connected to the bottom of the support plate 1. A first threaded rod 13 is rotatably connected to the upper part of the second fixing plate 12, and the first threaded rod 13 is threadedly connected to the support plate 1. The two first fixing plates 7 can clamp the bottom plate 36 by moving towards each other. When the first fixing plates 7 clamp the bottom plate 36, the telescopic plates 10 are contracted, and the telescopic plates 10 not in contact with the bottom plate 36 limit the bottom plate 36. Rotating the first threaded rod 13 drives the second fixing plate 12 to move downward and abut against the bottom plate 36;

[0033] A second connection assembly is arranged on the support plate 1. The second connection assembly includes a limiting plate 18 slidably arranged on the side surface of the expansion rod 2, a rotating ring 21 rotatably connected to the side surface of the support plate 1, a first fixing rope 24 and a second fixing rope 32 respectively installed on the outer side of the rotating ring 21, a first fixing block 25 installed at the end of the first fixing rope 24, and a second fixing block 33 installed at the end of the second fixing rope 32. The second fixing block 33 and the first fixing block 25 are connected in a snap-fit manner. A worm gear 22 is installed at the end of the rotating ring 21, and a worm 23 is rotatably connected to the side surface of the support plate 1. The worm 23 meshes with the worm gear 22. When the two first fixing plates 7 and the second fixing plate 12 clamp the support column 37, the limiting plate 18 is moved until the limiting plate 18 abuts tightly against the support column 37. Then, the second fixing block 33 and the first fixing block 25 are connected. The worm 23 is rotated, and the rotating ring 21 is driven to rotate through the worm gear 22. When the rotating ring 21 rotates, the first fixing rope 24 and the second fixing rope 32 are pulled to tighten the support column 37, which can provide a stable hanging point for the safety rope 4 of the staff and ensure safety during work.

[0034] A first sliding groove 5 is opened at the bottom of the support plate 1. First sliding blocks 6 are symmetrically and slidably arranged on the inner side of the first sliding groove 5. One side of the first sliding block 6 away from the expansion rod 2 is fixedly connected to the first fixing plate 7. A bidirectional threaded rod 34 is rotatably connected to the inner side of the first sliding groove 5, and the bidirectional threaded rod 34 is threadedly connected to the first sliding block 6. The acting force generated when the bidirectional threaded rod 34 rotates drives the two first sliding blocks 6 to move towards each other along the first sliding groove 5.

[0035] A plurality of first square grooves 8 are formed inside the first fixing plate 7. The telescopic plate 10 is slidably arranged inside the first fixing plate 7. A first spring 9 is installed inside the first square groove 8. The end of the first spring 9 is fixedly connected to the telescopic plate 10. When the telescopic plate 10 is squeezed by the bottom plate 36, it retracts into the inside of the first square groove 8.

[0036] The upper part of the second fixing plate 12 is provided with a movable rod 11. The movable rod 11 is slidably connected to the support plate 1. The second fixing plate 12 can move through the support of the movable rod 11.

[0037] A second sliding groove 14 is formed on the side surface of the telescopic rod 2. A second sliding block 15 is slidably arranged inside the second sliding groove 14. A second threaded rod 16 is rotatably connected inside the second sliding groove 14. The second threaded rod 16 is threadedly connected to the second sliding block 15. An arc-shaped plate 17 is installed on the side surface of the second sliding block 15. One end of the arc-shaped plate 17 away from the second sliding block 15 is fixedly connected to the limiting plate 18. When the second threaded rod 16 rotates, the acting force generated drives the second sliding block 15 to move along the second sliding groove 14.

[0038] A rotating rod 19 is rotatably connected inside the telescopic rod 2. A transmission belt 20 is sleeved jointly on the rotating rod 19 and the second threaded rod 16. When the rotating rod 19 rotates, it drives the second threaded rod 16 to rotate through the transmission belt 20.

[0039] A plurality of telescopic plates 10 are vertically and evenly distributed on the side surface of the first fixing plate 7, which is convenient for limiting the bottom plate 36.

[0040] In this embodiment, when the staff needs to hang the safety rope 4 when installing the main transformer 35, at this time, the two first fixing plates 7 can be directly placed on both sides of the bottom plate 36 at the bottom of the main transformer 35, and then the bidirectional threaded rod 34 is rotated. The acting force generated when the bidirectional threaded rod 34 rotates drives the two first sliding blocks 6 to move towards each other along the first sliding groove 5, and at the same time drives the first fixing plates 7 to move towards each other until the two first fixing plates 7 clamp the bottom plate 36. And at this time, the telescopic plate 10 in contact with the bottom plate 36 is squeezed by the bottom plate 36 and retracts into the inside of the first square groove 8. At this time, the first spring 9 contracts, and the telescopic plate 10 not in contact with the bottom plate 36 is at the edge of the bottom plate 36 to limit the bottom plate 36. Then the first threaded rod 13 can be rotated. The acting force generated by rotating the first threaded rod 13 drives the second fixing plate 12 to move away from the support plate 1 through the support of the movable rod 11 until it abuts against the bottom plate 36. In this way, through the combined use of the first fixing plate 7, the telescopic plate 10 and the second fixing plate 12, the support plate 1 is fixed on the bottom plate 36. Then the safety rope 4 is hung on the connecting hook 3 for use, and the height of the telescopic rod 2 is adjusted to ensure high hanging and low using.

[0041] Embodiment Two

[0042] As Figure 1 - Figure 8 shown, based on the first embodiment, a fixing groove 27 is formed on the side surface of the second fixing block 33, a limiting block 26 is installed on the side surface of the first fixing block 25, second square grooves 28 are symmetrically formed inside the fixing groove 27, a telescopic block 30 is slidably arranged inside the second square grooves 28, a second spring 29 is installed inside the second square grooves 28, the end of the second spring 29 is fixedly connected to the telescopic block 30, a round rod 31 is installed on one side of the telescopic block 30 close to the second spring 29, the round rod 31 is movably connected to the second fixing block 33, and the telescopic block 30 is inserted into the groove of the limiting block 26, so as to lock the limiting block 26 and realize the connection between the first fixing block 25 and the second fixing block 33.

[0043] The cross section of the telescopic block 30 is trapezoidal, and both telescopic blocks 30 are located on the movement track of the limiting block 26. When the limiting block 26 moves, it can squeeze the inclined surface of the telescopic block 30, and the size of the opening of the fixing groove 27 is adapted to the size of the limiting block 26.

[0044] The size of the opening of the groove of the limiting block 26 is adapted to the size of the telescopic block 30, ensuring the stability of the connection between the first fixing block 25 and the second fixing block 33.

[0045] In this embodiment, if the bottom plate 36 of the main transformer 35 does not support installation, the support plate 1 can be fixed to the support column 37 on the side of the main transformer 35 at this time. Place the two first fixing plates 7 on both sides of the support column 37, and then fix the support plate 1 to the support column 37 through the first fixing plate 7, the telescopic plate 10 and the second fixing plate 12. Then rotate the rotating rod 19. When the rotating rod 19 rotates, it drives the second threaded rod 16 to rotate through the transmission belt 20. The force generated when the second threaded rod 16 rotates drives the second sliding block 15 to move along the second sliding groove 14, and at the same time drives the limiting plate 18 to move through the arc-shaped plate 17 until the limiting plate 18 abuts against the support column 37, providing a more stable supporting force for the support plate 1. Then insert the limiting block 26 into the fixing groove 27. At the same time, the limiting block 26 can squeeze the inclined surface of the telescopic block 30, so that the telescopic block 30 retracts into the inner side of the second square groove 28. At this time, the second spring 29 contracts. When the groove of the limiting block 26 corresponds to the position of the telescopic block 30, the limiting block 26 no longer squeezes the telescopic block 30, and the second spring 29 in the contracted state drives the telescopic block 30 to reset, so that the telescopic block 30 is inserted into the groove of the limiting block 26, thereby locking the limiting block 26 and realizing the connection between the first fixing block 25 and the second fixing block 33. Then rotate the worm 23. Since the worm 23 meshes with the worm gear 22, the worm 23 drives the rotating ring 21 to rotate through the worm gear 22. When the rotating ring 21 rotates, it pulls the first fixing rope 24 and the second fixing rope 32, and tightens the support column 37 through the second fixing rope 32 and the first fixing rope 24, so as to stably fix the support plate 1 to the support column 37 on the side of the main transformer 35.

[0046] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
