A transformer oil storage cabinet support structure

Abstract

The present application relates to the technical field of transformer oil storage cabinets, and discloses a transformer oil storage cabinet support structure, including a first rectangular tube, a first rotating shaft, a ratchet, a rocker arm, a pawl, a tension spring, a claw, a drum, a rope, and a second rectangular tube. When in use, the four-corner rocker arm can reciprocate under the drive of an external force. Due to the tension of the four-corner tension spring, the four-corner pawl can always be against the four-corner ratchet. And, under the limiting action of the four-corner claw, the four-corner ratchet can only rotate continuously in a single direction. Therefore, the four-corner pawl can drive the four-corner ratchet to move intermittently in one direction, and finally drive the eight drums to rotate intermittently. The eight ropes are continuously wound around the eight drums, pulling the second rectangular tube and the transformer oil storage cabinet to move to the inside of the first rectangular tube until they are in a taut state. Compared with the method of driving the eight rotating shafts to rotate continuously to adjust the eight ropes to be taut, the operation is simple and easy to adjust.

Description

Technical Field

[0001] The present application relates to the technical field of transformer oil conservator cabinets, for example, to a transformer oil conservator cabinet support structure. Background Art

[0002] The related art (Announcement No.: CN114678194B) discloses a transformer oil storage cabinet support assembly, including a support frame and a mounting frame. A cable pulling mechanism is provided at each of the octagonal parts inside the support frame, and the oil storage cabinet body is detachably installed inside the mounting frame. The cable pulling mechanism includes U-shaped frames respectively embedded in the octagonal parts inside the support frame, and each U-shaped frame is rotatably connected to a rotating shaft inside, and the outside of each rotating shaft is coaxially fixedly connected to a reel and a ratchet in sequence from back to front. The upper end surface of each U-shaped frame is fixedly connected to a rotating column through a vertical rod, and each rotating column is hinged with a ratchet through a torsion spring, and each ratchet is engaged with the outside of the corresponding ratchet. Each reel is wound with a rope, and each end of the rope away from the corresponding reel is fixedly connected to a first pull ring, and each first pull ring is sleeved and connected to a second pull ring, and the eight second pull rings are respectively connected to the outside of the mounting frame.

[0003] In the process of implementing the above embodiments, it is found that there are at least the following problems in the related art:

[0004] The transformer oil conservator support assembly can rotate eight shafts before the oil conservator body is installed on the installation frame, so that the eight drums can be driven to rotate respectively, so that the eight ropes are wound and retracted. Then, the eight ratchets and eight pawls cooperate with each other to prevent the eight drums from reversing, so that the eight ropes are in a taut state. The eight taut ropes can reduce the vibration of the support frame and prevent the oil conservator body from falling off due to vibration. In the process of adjusting the eight ropes to be taut, the eight shafts need to be driven to rotate respectively, which makes the operation more troublesome.

[0018] The transformer oil storage cabinet support structure provided by the embodiment of the present disclosure can achieve the following technical effects:

[0019] The transformer oil storage cabinet support structure provided by the embodiment of the present disclosure includes a first rectangular tube, a first rotating shaft, a ratchet, a rocker arm, a pawl, a tension spring, a claw, a drum, a rope and a second rectangular tube. The first rectangular tube is used to be connected to a support frame fixed to the ground or the outer wall of the transformer, or directly placed on the ground or a high platform. The first rotating shaft is rotatably arranged at the four corners of the first rectangular tube along the length direction of the first rectangular tube, and the axes of the four corner first rotating shafts are parallel to each other and distributed in a rectangular shape, and can respectively perform rotational motion relative to the first rectangular tube. The ratchets are respectively installed on the four corner first rotating shafts and are all located outside the first rectangular tube. The four corner ratchets are respectively used to drive the four corner rotating shafts to perform rotational motion. The rockers are respectively rotatably installed on the four corner first rotating shafts, and the four corner rockers can respectively reciprocate relative to the four corner first rotating shafts. The pawls are respectively rotatably installed on the four corner rockers and respectively abut against the four corner ratchets. The four corner pawls and the four corner ratchets work together to respectively realize the intermittent rotation function of the four corner first rotating shafts. The tension springs are respectively installed between the four-corner rocker arms and the four-corner pawls, and are respectively used to provide tension, so that the four-corner pawls are always against the four-corner ratchet wheels under the action of the tension. The claws are respectively rotatably installed at the four corners of the outer wall of the first rectangular tube, and are respectively against the four-corner ratchet wheels, and are respectively used to limit the four-corner ratchet wheels, so that the four-corner ratchet wheels can be rotated continuously in a single direction. The reels are respectively installed at both ends of the four-corner first rotating shafts, and are all located inside the first rectangular tube. The eight reels rotate under the drive of the four-corner rotating shafts. The ropes are respectively wound around the eight reels and are rolled up under the drive of the eight reels. The second rectangular tube can be accommodated inside the first rectangular tube, and the eight ropes are respectively detachably connected to the octagonal parts of the second rectangular tube, and move to the inside of the first rectangular tube as the eight ropes are rolled up. The transformer oil storage cabinet is detachably installed inside the second rectangular tube, and after being installed inside the second rectangular tube, it moves with the movement of the second rectangular tube. The rocker arms at the four corners are controlled to rotate simultaneously so that the first rotating shafts at the four corners rotate intermittently.

[0020] During use, driven by external force, the rocker arms at the four corners can reciprocate. Due to the tension of the tension springs at the four corners, the pawls at the four corners can always resist the ratchet wheels at the four corners. And, under the limiting action of the claws at the four corners, the ratchet wheels at the four corners can only rotate continuously in a single direction. Therefore, as the rocker arms at the four corners swing back and forth clockwise and counterclockwise, the pawls at the four corners can drive the ratchet wheels at the four corners to move intermittently in one direction. Then, the first rotating shafts at the four corners are driven to rotate intermittently, and finally the eight drums are driven to rotate intermittently. The eight ropes are continuously wound around the eight drums, pulling the second rectangular cylinder and the transformer oil conservator to move to the inside of the first rectangular cylinder until they are in a taut state. When the eight ropes are in a taut state, the vibration of the transformer oil conservator can be reduced. Moreover, compared with the method of driving the eight rotating shafts to rotate continuously to adjust the eight ropes to be taut, the operation is simple and easy to adjust.

[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0042] Combination Figures 1 to 9As shown, the embodiment of the present disclosure provides a transformer oil storage cabinet support structure, including a first rectangular tube 1, a first rotating shaft 2, a ratchet 3, a rocker arm 4, a pawl 5, a tension spring 6, a claw 7, a drum 8, a rope 9 and a second rectangular tube 10. The first rectangular tube 1 is used to be connected to a support frame fixed to the ground or the outer wall of the transformer, or directly placed on the ground or a high platform. The first rotating shaft 2 is rotatably arranged at the four corners of the first rectangular tube 1 along the length direction of the first rectangular tube 1. The axes of the four-corner first rotating shafts 2 are parallel to each other and are distributed in a rectangular shape, and can rotate relative to the first rectangular tube 1. The ratchet wheels 3 are respectively installed on the four-corner first rotating shafts 2, and are all located outside the first rectangular tube 1. The four-corner ratchet wheels 3 are respectively used to drive the four-corner rotating shafts to rotate. The rocker arms 4 are rotatably installed on the four-corner first rotating shafts 2, and the four-corner rocker arms 4 can reciprocate relative to the four-corner first rotating shafts 2. The pawls 5 are rotatably mounted on the four-corner rocker arms 4, and are respectively against the four-corner ratchet wheels 3. The four-corner pawls 5 work in cooperation with the four-corner ratchet wheels 3 to respectively realize the intermittent rotation function of the four-corner first rotating shafts 2. The tension springs 6 are respectively mounted between the four-corner rocker arms 4 and the four-corner pawls 5, and are respectively used to provide tension, so that the four-corner pawls 5 are always against the four-corner ratchet wheels 3 under the action of the tension. The claws 7 are rotatably mounted on the four corners of the outer wall of the first rectangular tube 1, and are respectively against the four-corner ratchet wheels 3, and are respectively used to limit the four-corner ratchet wheels 3, so that the four-corner ratchet wheels 3 can be rotated continuously in a single direction. The reels 8 are respectively mounted on the two ends of the four-corner first rotating shafts 2, and are all located inside the first rectangular tube 1. The eight reels 8 rotate under the drive of the four-corner rotating shafts. The ropes 9 are respectively wound around the eight reels 8 and are rolled up under the drive of the eight reels 8. The second rectangular cylinder 10 can be accommodated inside the first rectangular cylinder 1, and the eight ropes 9 are detachably connected to the octagonal parts of the second rectangular cylinder 10, and move to the inside of the first rectangular cylinder 1 as the eight ropes 9 are rolled up. The transformer oil conservator is detachably installed inside the second rectangular cylinder 10, and after being installed inside the second rectangular cylinder 10, it moves with the movement of the second rectangular cylinder 10. Among them, the four-corner rocker arms 4 are controlled to rotate simultaneously, so that the four-corner first rotating shafts 2 rotate intermittently.

[0043] The embodiment of the present disclosure provides a transformer oil storage cabinet support structure, in which the rocker arms 4 at the four corners can reciprocate under the drive of external force. Due to the pulling force of the tension springs 6 at the four corners, the pawls 5 at the four corners can always resist the ratchet wheels 3 at the four corners. Moreover, under the limiting action of the claws 7 at the four corners, the ratchet wheels 3 at the four corners can only rotate continuously in a single direction. Therefore, as the rocker arms 4 at the four corners swing back and forth clockwise and counterclockwise, the pawls 5 at the four corners can drive the ratchet wheels 3 at the four corners to move intermittently in one direction. Then the first rotating shafts 2 at the four corners are driven to rotate intermittently, and finally the eight drums 8 are driven to rotate intermittently. The eight ropes 9 are continuously wound around the eight drums 8, pulling the second rectangular cylinder 10 and the transformer oil storage cabinet to move to the inside of the first rectangular cylinder 1 until they are in a taut state. When the eight ropes 9 are in a taut state, they can play a role in reducing the vibration of the transformer oil storage cabinet. Moreover, compared with the method of driving eight rotating shafts to rotate continuously to adjust the eight ropes 9 to be tight, the operation is simple and the adjustment is convenient.

[0044] Optionally, combined Figure 1 As shown, it also includes a first connecting rod 11, a second connecting rod 12, a third connecting rod 13 and a cylinder 14. The first connecting rod 11 is rotatably installed between the upper two angular rocker arms 4 and between the lower two angular rocker arms 4, and the first connecting rods 11 on both sides can rotate relative to the upper two angular rocker arms 4 and the lower two angular rocker arms 4, respectively. The straight lines where the first connecting rods 11 on both sides are located are parallel to each other, which is used to make the upper two angular rocker arms 4 and the lower two angular rocker arms 4 rotate synchronously. The second connecting rod 12 is rotatably installed on the first connecting rods 11 on both sides, and can rotate relative to the first connecting rods 11 on both sides, respectively, and is used to drive the first connecting rods 11 on both sides to move. The third connecting rod 13 is rotatably installed between the second connecting rods 12 on both sides, and can rotate relative to the second connecting rods 12 on both sides, respectively, and is used to drive the second connecting rods 12 on both sides to move. The cylinder 14 is installed on the outer wall of the first rectangular tube 1 along the width direction of the first rectangular tube 1, and the moving end of the cylinder 14 is connected to the third connecting rod 13 to provide a driving force to drive the third connecting rod 13 to perform linear motion. As the moving end of the cylinder 14 retracts and extends, the four-corner rocker arms 4 rotate simultaneously.

[0045] In the disclosed embodiment, the control cylinder 14 works, which can drive the third connecting rod 13 to move back and forth along the width direction of the first rectangular tube 1. Then, under the pulling or pushing of the second connecting rods 12 on both sides, the first connecting rods 11 on both sides can drive the rocker arms 4 at the four corners to swing back and forth. Finally, the eight ropes 9 are continuously wound around the eight drums 8, pulling the second rectangular tube 10 and the transformer oil storage cabinet to move to the inside of the first rectangular tube 1 until they are in a taut state. Therefore, only by controlling the operation of the cylinder 14, the rocker arms 4 at the four corners can be reciprocated at the same time, and finally the eight ropes 9 are in a straight state. Therefore, compared with the method of driving the rocker arms 4 at the four corners to rotate back and forth separately to adjust the eight ropes 9 to be taut, the operation is simpler and easier to adjust.

[0046] Optionally, combined Figure 1 and Figure 3 As shown, it also includes a first shaft support 15, a first optical axis 16 and a first metal sleeve 17. The first shaft support 15 is installed on the outer wall of the first rectangular tube 1, and is used to support and install the first optical axis 16. The first optical axis 16 is installed on the first shaft support 15 along the width direction of the first rectangular tube 1, and is penetrated by the third connecting rod 13, and is used to play a guiding and supporting role. The first metal sleeve 17 is slidably sleeved on the first optical axis 16, and is installed on the third connecting rod 13, and is used to reduce the friction between the first optical axis 16 and the third connecting rod 13.

[0047] In the disclosed embodiment, the first optical axis 16 is used to play the role of guide support to improve the stability of the third connecting rod 13 during reciprocating movement and reduce the radial force on the moving end of the cylinder 14. The first metal sleeve 17 is used to reduce the friction between the first optical axis 16 and the third connecting rod 13 and play a self-lubricating role, thereby improving the relative motion accuracy between the first optical axis 16 and the first metal sleeve 17.

[0048] Optionally, combined Figure 1 As shown, it also includes a fourth connecting rod 18, a fifth connecting rod 19, a sixth connecting rod 20 and a compression spring 21. The fourth connecting rod 18 is rotatably installed between the upper two corner claws 7 and the lower two corner claws 7, and the fourth connecting rods 18 on both sides can rotate relative to the upper two corner claws 7 and the lower two corner claws 7. The straight lines where the fourth connecting rods 18 on both sides are parallel to each other are used to make the upper two corner claws 7 and the lower two corner claws 7 rotate synchronously. The fifth connecting rod 19 is rotatably installed on the fourth connecting rods 18 on both sides, and can rotate relative to the fourth connecting rods 18 on both sides. The sixth connecting rod 20 is rotatably installed between the fifth connecting rods 19 on both sides, and can rotate relative to the fifth connecting rods 19 on both sides, and is used to drive the fifth connecting rods 19 on both sides to move. The compression spring 21 is installed between the outer wall of the first rectangular tube 1 and the sixth connecting rod 20, and is used to provide elastic force. Among them, under the elastic force of the compression spring 21, the four corner claws 7 are respectively against the four corner ratchet wheels 3.

[0049] In the disclosed embodiment, during the intermittent rotation of the ratchet wheels 3 at the four corners, when the tooth backs of the ratchet wheels 3 at the four corners are against the claws 7 at the four corners, the claws 7 at the four corners can be gradually pushed away from the center of the ratchet wheels 3 at the four corners, and then the fourth connecting rods 18 on both sides can be driven to move. Under the push of the fifth connecting rods 19 on both sides, the sixth connecting rod 20 can continuously press the compression spring 21, so that the compression spring 21 generates elastic force due to deformation. When the tooth grooves of the ratchet wheels 3 at the four corners are opposite to the claws 7 at the four corners, under the elastic force of the compression spring 21, the sixth connecting rod 20 can be reset. Then, under the push of the fifth connecting rods 19 on both sides, the fourth connecting rods 18 on both sides can drive the claws 7 at the four corners to rotate until they are engaged in the tooth grooves. Thereby, the claws 7 at the four corners can always be against the ratchet wheels 3 at the four corners to play a role of limiting. In addition, the claws 7 at the four corners can be reset at the same time, so as to avoid the eight ropes 9 being in different winding states due to the reverse rotation of one or more ratchets 3 due to slipping.

[0050] Optionally, combined Figure 1 and Figure 3 As shown, it also includes a second shaft support 22, a second optical axis 23 and a second metal sleeve 24. The second shaft support 22 is installed on the outer wall of the first rectangular tube 1, and is used to support and install the second optical axis 23. The second optical axis 23 is installed on the second shaft support 22 along the width direction of the first rectangular tube 1, and is penetrated by the sixth connecting rod 20, and is used to play a guiding and supporting role. The second metal sleeve 24 is slidably mounted on the second optical axis 23, and is installed on the sixth connecting rod 20, and is used to reduce the friction between the second optical axis 23 and the sixth connecting rod 20. Among them, the compression spring 21 is mounted on the second optical axis 23.

[0051] In the disclosed embodiment, the second optical axis 23 is used to play the role of guide support to improve the stability of the sixth connecting rod 20 when it moves back and forth, and to enable the compression spring 21 to be tightly compressed. The first metal sleeve 17 is used to reduce the friction between the second optical axis 23 and the sixth connecting rod 20, thereby improving the relative motion accuracy of the second optical axis 23 and the second metal sleeve 24. In addition, the design of the compression spring 21 sleeved on the second optical axis 23 can prevent the compression spring 21 from falling off between the first rectangular tube 1 and the sixth connecting rod 20.

[0052] Optionally, combined Figure 4 , Figure 6 , Figure 7 and Fig. 9As shown, it also includes a support block 25, a guide rail 26, a slider 27, a clamping block 28, a screw nut 29 and a ball screw 30. The support block 25 is mounted on the inner wall of the second rectangular tube 10 for supporting and installing the guide rail 26. The guide rail 26 is mounted on the support block 25 along the width direction of the first rectangular tube 1 for supporting and installing the slidable slider 27. The slider 27 is slidably mounted on the guide rail 26, and is located on both sides of the first rectangular tube 1 along the width direction of the first rectangular tube 1. The sliders 27 on both sides and the guide rail 26 together play a guiding and supporting role. The clamping blocks 28 are respectively mounted on the sliders 27 on both sides for clamping or loosening the transformer oil storage cabinet. The screw nuts 29 are respectively mounted on the clamping blocks 28 on both sides, and the center lines of the screw nuts 29 on both sides coincide with each other, and are respectively used to support and install the ball screws 30. The ball screws 30 are respectively mounted on the screw nuts 29 on both sides, and work with the screw nuts 29 on both sides to convert the rotational motion into the linear motion. The ball screws 30 on both sides are controlled to rotate simultaneously, so that the clamping blocks 28 on both sides move toward or in opposite directions.
