Description

Technical Field

[0001] This invention belongs to the field of busbar trunking, specifically relating to a double-shell shockproof fire-resistant busbar trunking and its assembly method. Background Technology

[0002] Busbar trunking is a power distribution device suitable for AC three-phase four-wire and three-phase five-wire systems, which transmits current. According to the insulation method, it can be divided into three types: air-insulated busbar trunking, compact insulated busbar trunking, and fire-resistant busbar trunking. It is used to distribute a large amount of power to various components of a distributed system. The compact busbar trunking consists of an external sheet metal busbar trunking body, a cover plate on the busbar trunking body, and conductive copper busbars placed in the area between the cover plate and the busbar trunking body. Insulating material is placed on the conductive copper busbars.

[0003] In existing technologies, when double-shell busbar trunking is used, it will be damaged if it is not subjected to seismic protection when subjected to pressure from above. However, when seismic protection is provided for busbar trunking, it is often only possible to provide single-stage seismic protection from above, and it is difficult to provide simultaneous lateral protection for the busbar trunking while providing single-stage seismic protection from above. This is an area that urgently needs improvement.

[0054] Another technical problem to be solved by the present invention is an assembly method for a double-shell shockproof fire-resistant busbar trunking.

[0055] S1. Assembly of the busbar trunking body as a whole: First, install the first conductive copper busbar support frame in the installation chamber of the busbar trunking housing, then install the second conductive copper busbar support frame in the installation chamber of the busbar trunking housing. Then, insert the conductive copper busbar first into the first conductive copper busbar support frame, and then insert it into the second conductive copper busbar support frame. Insert the pressing protrusion into the installation chamber of the busbar trunking housing, and then fit the cover plate against the upper wall of the busbar trunking housing.

[0056] S2. Assembly of the outer casing components: First, fasten the upper outer sheath ring to the top of the busbar trunking housing and fasten the lower outer sheath ring to the bottom of the busbar trunking housing, making the upper ear plate and the lower ear plate parallel to each other. The limiting screw is inserted into the upper ear plate and the lower ear plate in sequence to complete the locking between the upper outer sheath ring and the lower outer sheath ring. Then, assemble the second internal thread base onto the side of the busbar trunking housing.

[0057] S3. Adjustment of the lower outer sheath ring and the built-in buffer components as a whole: Rotate the first handwheel to make the right connecting screw and the left connecting screw rotate, so as to drive the two sets of the upper outer sheath rings to move closer or further away from each other, so as to drive the two sets of built-in buffer components to move closer or further away from each other.

[0058] S4. Anti-vibration operation on the side of the busbar housing: After the upper outer sheath ring moves, when the guide plate passes through the hole and touches the second inclined surface, it drives the insert plate to move upward to touch the trigger switch, so that the electric cylinder pushes the first connecting plate and the second connecting plate to extend along the side of the busbar housing. When the rubber pad is squeezed, it pushes the second connecting plate to move towards the side of the busbar housing, and at the same time squeezes the first spring to complete the anti-vibration operation on the side of the busbar housing.

[0059] S5. Perform anti-vibration work on the bus trunking housing in the direction from top to bottom: After the bus trunking housing is subjected to pressure from top to bottom, the fourth connecting plate will move down, and at the same time drive the external thread rod to move down, so as to squeeze the fourth spring downward, so as to complete the anti-vibration work on the bus trunking housing in the direction from top to bottom.

[0060] S6. Adjustment of the position of the limiting shaft seat: Loosen the first nut away from the side of the inner base, loosen the second nut away from the other side of the inner base, pull the inner screw out a distance from the inner base so that the limiting shaft seat can slide inside the inner base, then tighten the first nut to fit together with one side of the inner base, and then tighten the second nut to fit together with the other side of the inner base;

[0061] S7. Adjust the tension of the fourth spring: Rotate the internal threaded collar towards the buffer base to tighten the tension of the fourth spring, and rotate the internal threaded collar away from the buffer base to loosen the tension of the fourth spring.

[0062] S8. Perform secondary seismic protection on the busbar trunking shell from top to bottom: After the busbar trunking shell is subjected to pressure from top to bottom, and after the first seismic protection operation of the built-in buffer component, the third connecting plate is pushed down to drive the vertical insertion rod to move down and squeeze the second spring to complete the secondary seismic protection operation on the busbar trunking shell from top to bottom. At the same time, during the back-and-forth swaying of the busbar trunking shell, it is subject to the action of the third springs arranged in front and behind, which can perform seismic protection operation on the busbar trunking shell during the back-and-forth swaying.

[0063] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art include:

[0064] The present invention relates to a double-shell shockproof fire-resistant busbar trunking and its assembly method. Through the arrangement of outer shell components, an upper outer sheath ring is fastened to the top of the busbar trunking shell, and a lower outer sheath ring is fastened to the bottom of the busbar trunking shell, with the upper and lower ear plates arranged parallel to each other. A limiting screw is sequentially inserted into the upper and lower ear plates to complete the locking between the upper and lower outer sheath rings. The second internal thread base is then assembled onto the side surface of the busbar trunking shell to complete the positioning of the busbar trunking shell and the cover plate. When the first handwheel rotates, it drives the two sets of upper outer sheath rings to move closer or further apart, adjusting the shock-resistant position of the built-in buffer component in the left-right direction. Simultaneously, when the guide plate penetrates into the perforation and touches the second inclined surface, it drives the insert plate to move upwards to touch the second inclined surface. A trigger switch is activated so that the electric cylinder pushes the first and second connecting plates to extend along the side of the busbar housing. When the rubber pad is compressed, the second connecting plate is pushed to move towards the side of the busbar housing, while the first spring is compressed to complete the anti-vibration operation on the side of the busbar housing. Subsequently, the built-in buffer component can perform a primary anti-vibration operation on the busbar housing, and the tension of the fourth spring can be adjusted to control the magnitude of the anti-vibration force. In addition, the tilt height of the external threaded rod in the initial state can be adjusted by pulling the built-in base. The bottom anti-vibration component can perform a secondary anti-vibration operation on the busbar housing in the top-to-bottom direction, while also resisting vibrations caused by back-and-forth swaying.

[0079] In the embodiments, by Figure 1-10 Presented is a double-shell shockproof fire-resistant busbar trunking, wherein, Figure 1 This is a schematic diagram of the overall structure of the double-shell shockproof fire-resistant busbar trunking of the present invention; Figure 2 This is a structural schematic diagram of the double-shell shockproof fire-resistant busbar trunking from another perspective.

It includes a busbar trunking body 1, which includes a busbar trunking housing 11 containing an installation chamber and multiple sets of heat dissipation holes 12 on its side surfaces; a first conductive copper busbar support frame 13, detachably disposed within the installation chamber; a second conductive copper busbar support frame 17, detachably disposed within the installation chamber, located on one side of the first conductive copper busbar support frame 13, with a conductive copper busbar 14 passing through it and extending through the first conductive copper busbar support frame 13; and a cover plate 15, with a pressing protrusion 16 at its bottom, which is inserted into the busbar trunking housing 11 to... It is positioned on the busbar trunking shell 11; the outer protective shell component 2 is sleeved on the busbar trunking shell 11 and is used to position the cover plate 15 and the busbar trunking shell 11; the lateral shock-absorbing component 3 is detachably arranged on the cover plate 15 and is used to perform shock-absorbing work on the busbar trunking shell 11 from the side when it is touched by the outer protective shell component 2; the internal buffer component 5 is detachably arranged at the bottom of the outer protective shell component 2 and is used to perform shock-absorbing work on the busbar trunking shell 11 in the direction from top to bottom; and the bottom shock-absorbing component 4 is detachably installed at the bottom of the internal buffer component 5 and is used to perform secondary shock-absorbing work on the busbar trunking shell 11 in the direction from top to bottom.

[0080] The overall concept of this invention is as follows: The outer protective shell component 2 is used to fasten the upper outer sheath ring 21 to the top of the busbar trunking shell 11 and the lower outer sheath ring 23 to the bottom of the busbar trunking shell 11. The upper ear plate 22 and the lower ear plate 231 are arranged parallel to each other. A limiting screw 24 is sequentially inserted into the upper ear plate 22 and the lower ear plate 231 to complete the locking between the upper and lower outer sheath rings 21 and 23. The second internal thread base 29 is then assembled onto the side of the busbar trunking shell 11 to complete the positioning of the busbar trunking shell 11 and the cover plate 15. When the first handwheel 291 rotates, it drives the two sets of upper outer sheath rings 21 to move closer or further apart, adjusting the position of the built-in buffer component 5 in the left-right anti-vibration direction. Simultaneously, when the guide plate 211 penetrates into the through hole 32 and touches the second inclined surface 34, it drives the insert plate 33 to move upwards. When the trigger switch 37 is touched, the electric cylinder 38 pushes the first connecting plate 39 and the second connecting plate 392 to extend along the side of the busbar housing 11. When the rubber pad 393 is compressed, the second connecting plate 392 is pushed to move towards the side of the busbar housing 11, while the first spring 395 is compressed to complete the anti-vibration operation on the side of the busbar housing 11. After that, the built-in buffer member 5 can perform the first anti-vibration operation on the busbar housing 11, and the tension of the fourth spring 56 can be adjusted to control the magnitude of the anti-vibration force. In addition, the tilt height of the external thread rod 57 in the initial state can be adjusted by pulling the built-in base 51. The bottom anti-vibration member 4 can perform the second anti-vibration operation on the busbar housing 11 in the top-to-bottom direction, while also resisting the vibration caused by the back-and-forth shaking.

[0086] In some embodiments, more specifically, in order to further enhance the impact resistance of the second connecting substrate 392 after being impacted, a rubber pad 393 is detachably provided on the second connecting substrate 392, and the size of the rubber pad 393 is adapted to the size of the second connecting substrate 392.

[0087] Next, a more specific structure and construction of the built-in buffer component 5 will be provided for further explanation. The built-in buffer component 5 includes a built-in base 51 with a groove inside, in which a limiting shaft seat 52 is slidably arranged; a built-in lead screw 53, which is rotatably arranged in the built-in base 51, and a second handwheel 531 is detachably arranged on one end face; a first nut 532, which is rotatably arranged on the built-in lead screw 53 and is in contact with one side of the built-in base 51; a second nut 533, which is rotatably arranged on the built-in lead screw 53 and is in contact with the other side of the built-in base 51; and a buffer base 5. 4.

[0088] Next, the overall operating principle of the built-in buffer component 5 will be further explained. Loosen the first nut 532 away from the side of the built-in base 51, loosen the second nut 533 away from the other side of the built-in base 51, and pull the built-in screw 53 out of the built-in base 51 a certain distance so that the limiting shaft seat 52 can slide in the built-in base 51. Then tighten the first nut 532 to fit together with one side of the built-in base 51, and then tighten the second nut 533 to fit together with the other side of the built-in base 51.

[0089] In some embodiments, in order to prevent the external threaded rod 57 from falling out of the built-in buffer rod 55, an embedded slider is fixedly provided at one end of the built-in buffer rod 55 that passes through the external threaded rod 57. Two sets of inner sealing blocks are also detachably arranged on the inner circumferential wall of the external threaded rod 57. In the initial state, the embedded slider is located above the inner sealing block and the embedded slider is in contact with the inner sealing block.

[0090] Next, a more specific structure and construction of the bottom shock-absorbing component 4 will be given for further explanation. The bottom shock-absorbing component 4 includes a shock-absorbing base plate 41, on which an outer sleeve 42 is detachably arranged, and an inner sliding cavity is provided inside the outer sleeve 42; a vertical through rod 43, which is slidably arranged in the inner sliding cavity of the outer sleeve 42, and a second spring 44 is also sleeved on it; a guide ring 45, which is integrally formed on the end of the vertical through rod 43 away from the outer sleeve 42; a horizontal through rod 47, which is slidably arranged inside the guide ring 45; a third connecting base plate 46, which is passed through by the horizontal through rod 47 and is arranged parallel to the shock-absorbing base plate 41; a sealing block 48, which is detachably installed on one end of the horizontal through rod 47; and a third spring 49, which is slidably sleeved on the horizontal through rod 47 and is located between the third connecting base plate 46 and the guide ring 45.

[0091] Next, the overall working principle of the bottom shock-absorbing component 4 will be further explained. After the first shock-absorbing operation of the built-in buffer component 5, the third connecting plate 46 is pushed down to drive the vertical insertion rod 43 to move down and squeeze the second spring 44 to complete the second shock-absorbing operation of the busbar housing 11 in the direction from top to bottom. At the same time, during the back-and-forth swaying of the busbar housing 11, it is subject to the action of the third spring 49 arranged in front and behind, which can perform shock-absorbing operation on the busbar housing 11 during the back-and-forth swaying.

[0092] In some embodiments, more specifically, in order to further prevent the vertical insertion rod 43 from falling out of the outer sleeve 42, a displacement block is detachably provided on one end of the vertical insertion rod 43 that penetrates into the inner sliding cavity of the outer sleeve 42, and two sealing blocks are integrally formed on the top of the inner cavity wall of the outer sleeve 42. In the initial state, the displacement block is located below the two sets of sealing blocks.

[0093] Another technical problem to be solved by the present invention is an assembly method for a double-shell shockproof fire-resistant busbar trunking.

[0094] S1. Assembly of the busbar trunking body 1 as a whole: First, install the first conductive copper busbar support frame 13 in the mounting chamber of the busbar trunking housing 11, then install the second conductive copper busbar support frame 17 in the mounting chamber of the busbar trunking housing 11, then insert the conductive copper busbar 14 first into the first conductive copper busbar support frame 13, then insert it into the second conductive copper busbar support frame 17, then snap the pressing protrusion 16 into the mounting chamber of the busbar trunking housing 11, and finally fit the cover plate 15 against the upper wall of the busbar trunking housing 11.

[0095] S2. Assembly of the outer housing component 2: First, fasten the upper outer sheath ring 21 to the top of the busbar housing 11, and fasten the lower outer sheath ring 23 to the bottom of the busbar housing 11, so that the upper ear plate 22 and the lower ear plate 231 are arranged in parallel. The limiting screw 24 is inserted into the upper ear plate 22 and the lower ear plate 231 in sequence to complete the locking between the upper outer sheath ring 21 and the lower outer sheath ring 23. Then, assemble the second internal thread base 29 onto the side of the busbar housing 11.

[0096] S3. Adjustment of the lower outer sheath ring 23 and the built-in buffer component 5 as a whole: Rotate the first handwheel 291 to make the right connecting screw 28 and the left connecting screw 26 rotate, so as to drive the two sets of upper outer sheath rings 21 to move closer or further away from each other, so as to drive the two sets of built-in buffer components 5 to move closer or further away from each other.

[0097] S4. Anti-vibration operation on the side of the busbar housing 11: After the upper outer sheath ring 21 moves, when the guide plate 211 passes into the through hole 32 and touches the second inclined surface 34, it drives the insert plate 33 to move upward to touch the trigger switch 37, so that the electric cylinder 38 pushes the first connecting plate 39 and the second connecting plate 392 to extend along the side of the busbar housing 11. When the rubber pad 393 is squeezed, it pushes the second connecting plate 392 to move towards the side of the busbar housing 11, while squeezing the first spring 395 to complete the anti-vibration operation on the side of the busbar housing 11.

[0098] S5. Perform anti-vibration work on the bus trunking housing 11 in the direction from top to bottom: After the bus trunking housing 11 is subjected to pressure from top to bottom, the fourth connecting plate 591 will move down, and the external thread rod 57 will be driven to move down to squeeze the fourth spring 56 downward, so as to complete the anti-vibration work on the bus trunking housing 11 in the direction from top to bottom.

[0099] S6. Adjustment of the position of the limiting shaft seat 52: Loosen the first nut 532 away from the side of the inner base 51, loosen the second nut 533 away from the other side of the inner base 51, pull the inner screw 53 out of the inner base 51 a certain distance so that the limiting shaft seat 52 can slide in the inner base 51, tighten the first nut 532 to fit together with one side of the inner base 51, and then tighten the second nut 533 to fit together with the other side of the inner base 51.

[0100] S7. Adjust the tension of the fourth spring 56: Rotate the internal threaded collar 58 towards the buffer base 54 to tighten the tension of the fourth spring 56, and rotate the internal threaded collar 58 away from the buffer base 54 to loosen the tension of the fourth spring 56.

[0101] S8. Perform secondary anti-vibration work on the busbar trunking housing 11 from top to bottom: After the busbar trunking housing 11 is subjected to pressure from top to bottom, and after the first anti-vibration work of the built-in buffer component 5, the third connecting plate 46 is pushed down to drive the vertical insertion rod 43 to move down and squeeze the second spring 44 to complete the secondary anti-vibration work on the busbar trunking housing 11 from top to bottom. At the same time, during the back-and-forth swaying of the busbar trunking housing 11, it is subject to the action of the third spring 49 arranged in front and behind, which can perform anti-vibration work on the busbar trunking housing 11 during the back-and-forth swaying.

[0102] In summary, the outer casing component 2 is used to fasten the upper outer sheath ring 21 to the top of the busbar trunking housing 11 and the lower outer sheath ring 23 to the bottom of the busbar trunking housing 11, with the upper ear plate 22 and the lower ear plate 231 arranged parallel to each other. The limiting screw 24 is inserted into the upper ear plate 22 and the lower ear plate 231 in sequence to complete the locking between the upper outer sheath ring 21 and the lower outer sheath ring 23. When the second internal thread base 29 is assembled onto the side of the busbar trunking housing 11, the positioning of the busbar trunking housing 11 and the cover plate 15 can be completed. When the first handwheel 291 is rotated, it is used to drive the two sets of upper outer sheath rings 21 to move closer or further apart to adjust the position of the built-in buffer component 5 in the left and right direction for shock resistance. At the same time, when the guide plate 211 is inserted into the through hole 32 and touches the second inclined surface 34, it is used to drive the insert plate 33 to move upward to touch the trigger opening. The valve 37 is closed so that the electric cylinder 38 pushes the first connecting plate 39 and the second connecting plate 392 to extend along the side of the busbar housing 11. When the rubber pad 393 is compressed, the second connecting plate 392 is pushed to move towards the side of the busbar housing 11, while the first spring 395 is compressed to complete the anti-vibration operation on the side of the busbar housing 11. After that, the built-in buffer member 5 can perform the first anti-vibration operation on the busbar housing 11, and the tension of the fourth spring 56 can be adjusted to control the magnitude of the anti-vibration force. In addition, the tilt height of the external thread rod 57 in the initial state can be adjusted by pulling the built-in base 51. The bottom anti-vibration member 4 can perform the second anti-vibration operation on the busbar housing 11 in the direction from top to bottom, while resisting the vibration caused by the back and forth shaking.
