Description

Technical Field

[0002] In related technologies, GIL (Gas Insulated Transmission Lines) equipment laid in tunnels plays a crucial role in urban power systems. GIL equipment includes a support structure, a housing, and the GIL itself. The housing protects the internal GIL, while the support structure includes crossbeams for fixing to the tunnel and brackets for securing the housing. During GIL installation, each housing must be positioned according to specifications to ensure the stability of the GIL system. However, in actual installation, manufacturing defects and environmental factors can cause positional deviations between the crossbeams and the brackets connecting to the housing, hindering installation. While existing technologies have proposed using multiple studs to adjust the relative positions of the brackets and crossbeams to eliminate these deviations, the adjustment process remains complex.

[0047] Please refer to Figure 1-3 As shown, this utility model proposes a support device 10 for fixing the outer shell 20 for accommodating GIL, including a crossbeam 100, a bracket 200, a connecting assembly 300, a first fastener 410 and a second fastener 420.

[0048] The crossbeam 100 has a positioning through hole 110. The bracket 200 includes a frame 210, a first fixing block 220, and a second fixing block 230. The frame 210 is used to connect to the outer shell 20. The first fixing block 220 and the second fixing block 230 are both connected to the frame 210 and are respectively located on both sides of the crossbeam 100 in the axial direction of the positioning through hole 110. The first fixing block 220 has a first through hole 221, and the second fixing block 230 has a second through hole 231. The connecting assembly 300 includes a connecting rod 310, which passes through the first through hole 221, the second through hole 231, and the positioning through hole 110, and is fixed to the crossbeam 100.

[0049] Please refer to Figure 3 As shown, when the connecting rod 310 is fixed to the crossbeam 100 and the connecting rod 310 is fixed in the first through hole 221 and the second through hole 231, the connecting rod 310 passing through the first through hole 221 and the second through hole 231 can limit the displacement of the first fixing block 220 and the second fixing block 230 along the radial direction of the connecting rod 310, thereby limiting the overall displacement of the bracket 200 along the radial direction of the connecting rod 310.

[0050] The support device 10 of this utility model further includes a first fastener 410 and a second fastener 420, both of which are threadedly connected to the connecting rod 310. A first fixing block 220 with a first through hole 221 and a second fixing block 230 with a second through hole 231 are respectively disposed on both sides of the crossbeam 100 around the positioning through hole 110. Please refer to Figure 3 As shown, when the operator rotates the first fastener 410, the first fastener 410 can move along the thread on the connecting rod 310 along the axial direction of the connecting rod 310, thereby changing the axial position of the first fastener 410 relative to the connecting rod 310 and the position of the first fastener 410 relative to the second fastener 420; when the operator rotates the second fastener 420, the second fastener 420 can move along the thread on the connecting rod 310 along the axial direction of the connecting rod 310, thereby changing the axial position of the second fastener 420 relative to the connecting rod 310 and the position of the second fastener 420 relative to the first fastener 410.

[0051] The first fastener 410 of this utility model abuts against the first fixing block 220, and the second fastener 420 abuts against the second fixing block 230. The first fastener 410 will be fixed to the connecting rod 310 by the force of the first fixing block 220. The movement of the first fixing block 220 toward the first fastener 410 will be restricted by the first fastener 410, and the rotation of the first fixing block 220 around the connecting rod 310 will also be restricted by the friction of the first fastener 410. The second fastener 420 will be fixed to the connecting rod 310 by the force of the second fixing block 230. The movement of the second fixing block 230 toward the second fastener 420 will be restricted by the second fastener 420, and the rotation of the second fixing block 230 around the connecting rod 310 will also be restricted by the friction of the second fastener 420.

[0052] Please refer to Figure 3 As shown, in some embodiments, the first fastener 410 is located on the side of the first fixing block 220 away from the positioning through hole 110 (e.g., Figure 3 The first fastener 410 shown is located on the right side of the first fixing block 220, and the second fastener 420 is located on the side of the second fixing block 230 away from the positioning through hole 110 (e.g., Figure 3 The second fastener 420 shown is located to the left of the second fixing block 230. Since the first fixing block 220, the second fixing block 230 and the frame 210 are interconnected, the first fastener 410 in the above embodiment will restrict the overall support 200 along the positive direction of the connecting rod 310 (that is...). Figure 3 The second fastener 420 will restrict the entire bracket 200 from moving in the opposite direction (i.e., to the left) along the connecting rod 310. Figure 3 (As shown in the right direction) the bracket 200 moves axially along the connecting rod 310, and the movement of the bracket 200 as a whole is completely restricted by the first fastener 410 and the second fastener 420.

[0053] In some embodiments, the first fastener 410 is located on the side of the first fixing block 220 near the positioning through hole 110 (e.g., Figure 3 The first fastener 410 shown is located on the right side of the first fixing block 220, and the second fastener 420 is located on the side of the second fixing block 230 near the positioning through hole 110 (e.g., Figure 3 The second fastener 420 shown is located to the left of the second fixing block 230. Since the first fixing block 220, the second fixing block 230 and the frame 210 are interconnected, the second fastener 420 in the above embodiment will restrict the overall support 200 along the positive direction of the connecting rod 310 (that is...). Figure 3 The first fastener 410 will restrict the entire bracket 200 from moving in the opposite direction (i.e., to the left) along the connecting rod 310. Figure 3(As shown in the right direction) the bracket 200 moves axially along the connecting rod 310, and the movement of the bracket 200 as a whole is completely restricted by the first fastener 410 and the second fastener 420.

[0054] In summary, this invention uses a first fastener 410, a second fastener 420, and a connecting rod 310 to fix the bracket 200 onto the crossbeam 100. Since the first fastener 410 and the second fastener 420 are threaded onto the connecting rod 310, workers can adjust the positions of the first fastener 410 and the second fastener 420 on the connecting rod 310 by rotating them. This, in turn, adjusts the position of the first fixing block 220 and the second fixing block 230 against the bracket 200, thereby adjusting the position of the bracket 200 relative to the crossbeam 100. This invention can adjust the relative position between the outer shell 20 and the crossbeam 100 simply by adjusting the axial position of the two fasteners on the connecting rod 310, resulting in higher adjustment efficiency.

[0055] In the existing technology, there is also a solution of directly welding the crossbeam 100 and the bracket 200. This utility model can fix the bracket 200 and the crossbeam 100 by mechanical connection of the first fastener 410, the second fastener 420 and the connecting rod 310, avoiding open flame operation, reducing the generation of sparks and smoke, and thus reducing the pollution of the construction environment.

[0056] Further, please refer to Figure 2 As shown, in some embodiments, the crossbeam 100 has two positioning through holes 110, which are arranged along the extending direction of the crossbeam 100; the bracket 200 includes two first fixing blocks 220 and two second fixing blocks 230, each of the first fixing blocks 220 and each of the second fixing blocks 230 being connected to the same frame 210; the connecting assembly 300 includes two connecting rods 310, which pass through different positioning through holes 110, first through holes 221 and second through holes 231 respectively; the support device 10 also includes two first fasteners 410 and two second fasteners 420; each connecting rod 310 is threadedly connected to one first fastener 410 and one second fastener 420, and each fastener abuts against a fixing block. The above solution can further reduce the rotation of the bracket 200 relative to the connecting rods 310, thereby further fixing the relative position between the outer shell 20 and the crossbeam 100.

[0057] Without departing from the inventive concept of this utility model, those skilled in the art can choose their own method to fix the connecting rod 310 to the crossbeam 100.

[0058] Please refer to Figure 3 , Figure 4 As shown, where Figure 3 , Figure 5The third and fourth fasteners are not shown. In some embodiments, the positioning through hole 110 has a first opening 111 and a second opening 112 on both sides in the axial direction. The support device 10 also includes a third fastener and a fourth fastener, both of which are threadedly connected to the connecting rod 310 along the axial direction. The third fastener abuts against the edge of the first opening 111, and the fourth fastener abuts against the edge of the second opening 112. With the above scheme, the abutment of the edge of the first opening 111 against the third fastener can restrict the overall movement of the connecting rod 310 toward the first opening 111 and restrict the rotation of the connecting rod 310 relative to the crossbeam 100. The abutment of the edge of the second opening 112 against the fourth fastener can restrict the overall movement of the connecting rod 310 toward the second opening 112 and similarly restrict the rotation of the connecting rod 310 relative to the crossbeam 100. The movement of the connecting rod 310 relative to the crossbeam 100 is completely restricted by the third and fourth fasteners, that is, the connecting rod 310 is fixed to the crossbeam 100.

[0059] It should be noted that although both the third and fourth fasteners are threaded to the connecting rod 310, the above embodiment still allows adjustment of the position of the outer casing 20 relative to the crossbeam 100 by adjusting the positions of the first fastener 410 and the second fastener 420 while the connecting rod 310 and the crossbeam 100 remain relatively stationary. Under this premise, since both the third and fourth fasteners are threaded to the connecting rod 310, the operator can further adjust the position of the connecting rod 310 relative to the crossbeam 100 by adjusting the positions of the first fastener 410 and the second fastener 420, thereby adjusting the position of the outer casing 20 relative to the crossbeam 100, increasing the overall adjustment stroke of the support device 10.

[0060] Please refer to Figure 3 , Figure 4 As shown, in some embodiments, the positioning through hole 110 has a first opening 111 and a second opening 112 on both sides in the axial direction. The support device 10 also includes a first wedge 510. From the second opening 112 to the first opening 111, the area of ​​the cross section of the first wedge 510 in the axial direction perpendicular to the connecting rod 310 gradually decreases. The first wedge 510 is inserted between the inner wall of the positioning through hole 110 and the connecting rod 310 through the second opening 112, and simultaneously abuts against the inner wall of the positioning through hole 110 and the connecting rod 310.

[0061] The first wedge 510 can be inserted between the inner wall of the positioning through hole 110 and the connecting rod 310 through the second opening 112, and simultaneously abut against the inner wall of the positioning through hole 110 and the connecting rod 310. This restricts the axial movement and perpendicular axial movement of the connecting rod 310 by the inner wall of the positioning through hole 110 and the first wedge 510, allowing the connecting rod 310 to be completely fixed to the crossbeam 100. Since the cross-sectional area of ​​the first wedge 510 gradually decreases in the axial direction perpendicular to the connecting rod 310, the operator can adjust the tightness between the connecting rod 310 and the crossbeam 100 by adjusting the specific position of the first wedge 510 abutting against the connecting rod 310 and against the inner wall of the positioning through hole 110.

[0062] On the other hand, for different support devices 10, the assembly gap between the inner wall of the positioning through hole 110 and the connecting rod 310 is different. Therefore, the workers can also adjust the specific position of the first wedge 510 abutting against the connecting rod 310 and against the inner wall of the positioning through hole 110 to ensure that the tightness between the connecting rod 310 and the crossbeam 100 can be kept consistent.

[0063] For example, please refer to Figure 3 , Figure 4 As shown, during installation, the first wedge 510 needs to be positioned along the direction from the second opening 112 to the first opening 111 (i.e., Figure 3 , Figure 4 As shown in the diagram (from left to right), the first wedge 510 is inserted between the inner wall of the connecting rod 310 and the positioning through hole 110. When the assembly gap between the connecting rod 310 and the positioning through hole 110 is small, the operator can reduce the degree to which the first wedge 510 is inserted into the positioning through hole 110; when the assembly gap between the connecting rod 310 and the positioning through hole 110 is large, the operator can increase the degree to which the first wedge 510 is inserted into the positioning through hole 110.

[0064] Please refer to Figure 4 As shown, in some embodiments, the support device 10 includes a plurality of wedges, which are simultaneously inserted into the space between the inner wall of the positioning through hole 110 and the connecting rod 310 along the direction from the second opening 112 to the first opening 111, filling the gap between the inner wall of the positioning through hole 110 and the connecting rod 310. This allows the operator to more flexibly adjust the tightness between the connecting rod 310 and the crossbeam 100 by adjusting the specific positions of the multiple wedges against the connecting rod 310 and against the inner wall of the positioning through hole 110.

[0065] In some embodiments, the support device 10 includes a plurality of wedges. A plurality of wedges are inserted between the inner wall of the positioning through hole 110 and the connecting rod 310 along a direction from the second opening 112 to the first opening 111, filling the gap between the inner wall of the positioning through hole 110 and the connecting rod 310. A plurality of wedges are also inserted between the inner wall of the positioning through hole 110 and the connecting rod 310 along a direction from the first opening 111 to the second opening 112, filling the gap between the inner wall of the positioning through hole 110 and the connecting rod 310. The wedges in this embodiment can further increase the tightness between the connecting rod 310 and the crossbeam 100.

[0066] Further, please refer to Figure 3 , Figure 4 , Figure 5 As shown, the inner wall of the positioning through hole 110 and the connecting rod 310 are spaced apart radially from each other. The connecting assembly 300 also includes a first limiting member 320, which is connected radially to the connecting rod 310. The first limiting member 320 and the connecting rod 310 can pass through the positioning through hole 110, and the first limiting member 320 can abut against the edge of the first opening 111. Since the first limiting member 320 connected radially to the connecting rod 310 can pass through the positioning through hole 110 with the connecting rod 310, the first limiting member 320 will not affect the installation of the connecting rod 310. Furthermore, since the first limiting member 320 can abut against the edge of the first opening 111, when the first wedge 510 is inserted, the first limiting member 320 can limit the connecting rod 310, making the installation of the first wedge 510 more convenient.

[0067] On the other hand, the first limiting member 320 can further restrict the movement of the connecting rod 310 from the second opening 112 to the first opening 111 by abutting against the edge of the first opening 111, thereby further increasing the tightness between the connecting rod 310 and the crossbeam 100.

[0068] In some embodiments, the connecting assembly 300 includes a plurality of first limiting members 320, each first limiting member 320 being connected radially to the connecting rod 310. The plurality of first limiting members 320 and the connecting rod 310 can pass through the positioning through hole 110, and each first limiting member 320 can abut against the edge of the first opening 111. The above embodiments further limit the connecting rod 310 by the abutment of the plurality of first limiting members 320 against the edge of the first opening 111.

[0069] Based on the above embodiments, please refer to some embodiments. Figure 5 As shown, the first limiting member 320 is integrally connected to the connecting rod 310. The first limiting member 320 integrally connected to the connecting rod 310 can further enhance the limiting effect on the connecting rod 310, thereby further strengthening the tightness of the connection between the connecting rod 310 and the crossbeam 100.

[0070] It should be noted that this utility model does not limit the specific manner in which the first limiting member 320 and the connecting rod 310 pass through the positioning through hole 110. Those skilled in the art can adjust the specifications of the positioning through hole 110 so that the connecting assembly 300 can pass through it. As a preferred embodiment, please refer to... Figure 2 As shown, Figure 2 The first through hole 221, the second through hole 231, and the positioning through hole 110 have the same shape, and the areas enclosed by the edges of the first through hole 221, the second through hole 231, and the positioning through hole 110 overlap in projection on a plane perpendicular to the front-back direction. The positioning through hole 110 is an oblong hole extending in the vertical direction. The length of the connecting rod 310 in the left-right direction is the same as the length of the positioning through hole 110 in the left-right direction. During installation, the first limiting member 320 can be positioned above or below the connecting rod 310 by rotating the connecting rod 310. The first limiting member 320 and the connecting rod 310 can pass through the positioning through hole 110 together. After the first limiting member 320 passes through the positioning through hole 110, it rotates relative to the connecting rod 310, so that the first limiting member 320 can abut against the left or right side of the edge of the first opening 111, achieving abutment between the first limiting member 320 and the crossbeam 100. Further, please refer to Figure 3 , Figure 4 As shown, in some embodiments, there is a gap between the upper part of the inner wall of the positioning through hole 110 and the upper part of the connecting rod 310. The upward-facing side of the crossbeam 100 supports the bracket 200. The first wedge 510 is inserted between the upper part of the inner wall of the positioning through hole 110 and the upper part of the connecting rod 310 through the second opening 112. With the above solution, during the installation of the bracket 200, the worker can first place the bracket 200 on the crossbeam 100 so that the crossbeam 100 supports the frame 210. The worker does not need to continuously lift the bracket 200 by hand or other auxiliary tools, making the installation more convenient. On the other hand, after the support device 10 is installed, the first wedge 510 can fill the gap between the upper part of the connecting rod 310 and the upper part of the positioning through hole 110, so that the upward-facing side of the crossbeam 100 abuts against the frame 210, thereby fixing the bracket 200 as a whole by the abutment between the upper part of the crossbeam 100 and the inner wall of the positioning through hole 110.

[0071] As a preferred option, please refer to Figure 3 , Figure 4As shown, in some embodiments, the support device 10 further includes a second wedge 520. From the second opening 112 to the first opening 111, the area of ​​the cross-section of the second wedge 520 perpendicular to the axial direction of the connecting rod 310 gradually decreases. There is a gap between the lower part of the inner wall of the positioning through hole 110 and the lower part of the connecting rod 310. The second wedge 520 is inserted through the second opening 112 between the lower part of the inner wall of the positioning through hole 110 and the lower part of the connecting rod 310, and simultaneously abuts against the inner wall of the positioning through hole 110 and the connecting rod 310. When the support device 10 is subjected to impact, the second wedge 520 located below the connecting rod 310 can absorb the downward vibration of the connecting rod 310, improving the stability of the connecting rod 310 and thus extending the overall service life of the connecting rod 310.

[0072] Further, please refer to Figure 3 , Figure 4 , Figure 5 As shown, the connecting assembly 300 also includes a second limiting member 330, which is connected radially to the connecting rod 310. The second limiting member 330 is located on the side of the positioning through hole 110 near the second opening 112. The second limiting member 330 and the connecting rod 310 can pass through the positioning through hole 110, and the second limiting member 330 can abut against the edge of the second opening 112. The second limiting member 330 can further restrict the movement of the connecting rod 310 from the first opening 111 to the second opening 112 by abutting against the edge of the second opening 112, further increasing the tightness between the connecting rod 310 and the crossbeam 100.

[0073] Based on the above embodiments, please refer to some embodiments. Figure 5 As shown, the second limiting member 330 is integrally connected to the connecting rod 310. The second limiting member 330 integrally connected to the connecting rod 310 can further enhance the limiting effect on the connecting rod 310, thereby further strengthening the tightness of the connection between the connecting rod 310 and the crossbeam 100.

[0074] In some embodiments, the connecting assembly 300 includes a plurality of second limiting members 330, each second limiting member 330 being connected radially to the connecting rod 310. The plurality of second limiting members 330 and the connecting rod 310 can pass through the positioning through hole 110, and each second limiting member 330 can abut against the edge of the second opening 112. The above embodiments further limit the connecting rod 310 by the abutment of the plurality of second limiting members 330 against the edge of the second opening 112.

[0075] In some embodiments, please refer to Figure 5As shown, the first limiting member 320 and the second limiting member 330 are both connected to the radial direction of the connecting rod 310. The first limiting member 320 and the second limiting member 330 can jointly restrict the axial movement of the connecting rod 310 by abutting against the crossbeam 100, which makes it easier for the staff to position the connecting rod 310 and facilitates the subsequent fixing of the first fastener 410 and the second fastener 420.

[0076] It should be noted that this utility model does not limit the specific manner in which the second limiting member 330 and the connecting rod 310 pass through the positioning through hole 110. Those skilled in the art can adjust the specifications of the positioning through hole 110 so that the connecting assembly 300 can pass through it. As a preferred embodiment, please refer to... Figure 2 As shown, Figure 2 The first through hole 221, the second through hole 231, and the positioning through hole 110 have the same shape, and the areas enclosed by the edges of the first through hole 221, the second through hole 231, and the positioning through hole 110 overlap in projection on a plane perpendicular to the front-back direction. The positioning through hole 110 is an oblong hole extending in the vertical direction. The length of the connecting rod 310 in the left-right direction is the same as the length of the positioning through hole 110 in the left-right direction. During installation, the second limiting member 330 can be positioned above or below the connecting rod 310 by rotating the connecting rod 310. The second limiting member 330 and the connecting rod 310 can pass through the positioning through hole 110 together. After the second limiting member 330 passes through the positioning through hole 110, it rotates relative to the connecting rod 310, so that the second limiting member 330 can abut against the left or right side of the edge of the second opening 112, achieving abutment between the second limiting member 330 and the crossbeam 100. Further, please refer to Figure 3 , Figure 4 , Figure 6 As shown, in some embodiments, on a projection plane perpendicular to the axial direction of the positioning through hole 110, the projection of the second limiting member 330 on the projection plane is the first projection, and the projection of the first wedge 510 on the projection plane is the second projection; the first projection and the second projection are offset. Because the first projection and the second projection are offset, the first wedge 510 can avoid the second limiting member 330 during the process of inserting the connecting rod 310 and the inner wall of the positioning through hole 110 in the direction from the second opening 112 to the first opening 111, which is beneficial for the workers to install the first wedge 510.

[0077] Further, please refer to Figure 3As shown, in some embodiments, the support device 10 further includes a third wedge 530, the area of ​​which gradually decreases in the cross-section perpendicular to the axial direction of the connecting rod 310; the inner wall of the first through hole 221 and the connecting rod 310 are spaced radially apart; the third wedge 530 is inserted between the inner wall of the first through hole 221 and the connecting rod 310, and simultaneously abuts against the inner wall of the first through hole 221 and the connecting rod 310. With this solution, the rotation of the first fixing block 220 around the connecting rod 310, its movement along the axial direction of the connecting rod 310, and its movement perpendicular to the axial direction of the connecting rod 310 are all restricted by the inner wall of the first through hole 221 and the third wedge 530, allowing the first fixing block 220 to be further fixed to the connecting rod 310. As the area of ​​the cross section of the third wedge 530 in the axial direction perpendicular to the connecting rod 310 gradually decreases, the operator can adjust the tightness between the connecting rod 310 and the crossbeam 100 by adjusting the specific position of the third wedge 530 abutting against the connecting rod 310 and against the inner wall of the first through hole 221.

[0078] On the other hand, for different support devices 10, the assembly gap between the inner wall of the first through hole 221 and the connecting rod 310 is different. The operator can also adjust the specific position of the third wedge 530 abutting against the connecting rod 310 and against the inner wall of the first through hole 221 to ensure that the tightness of the connecting rod 310 and the first fixing block 220 can be kept consistent.

[0079] In some embodiments, the support device 10 further includes a fourth wedge, the area of ​​which gradually decreases in the cross-sectional area perpendicular to the axial direction of the connecting rod 310; the inner wall of the second through hole 231 and the connecting rod 310 are spaced radially apart; the fourth wedge is inserted between the inner wall of the second through hole 231 and the connecting rod 310, and simultaneously abuts against the inner wall of the second through hole 231 and the connecting rod 310. With this solution, the rotation of the second fixing block 230 around the connecting rod 310, its movement along the axial direction of the connecting rod 310, and its movement perpendicular to the axial direction of the connecting rod 310 are all restricted by the inner wall of the second through hole 231 and the fourth wedge, allowing the second fixing block 230 to be further fixed to the connecting rod 310. As the area of ​​the fourth wedge in the axial direction perpendicular to the connecting rod 310 gradually decreases, the operator can adjust the tightness between the connecting rod 310 and the crossbeam 100 by adjusting the specific position of the fourth wedge abutting against the connecting rod 310 and against the inner wall of the second through hole 231.

[0080] On the other hand, for different support devices 10, the assembly gap between the inner wall of the second through hole 231 and the connecting rod 310 is different. The operator can also ensure the tightness of the connecting rod 310 and the second fixing block 230 by adjusting the specific position of the fourth wedge against the connecting rod 310 and against the inner wall of the second through hole 231.

[0081] Without departing from the inventive concept of this utility model, those skilled in the art can simultaneously provide a third wedge 530 and a fourth wedge to further increase the tightness between the bracket 200 and the connecting rod 310.

[0082] This invention also proposes a GIL (Gas Injection Line) device, which includes a support device 10 as described in any of the above embodiments and a housing 20. A frame 210 is connected to the housing 20, which protects the GIL. By rotating the first fastener 410 and the second fastener 420, the operator can adjust the relative position of the housing 20 and the crossbeam 100 along the axial direction of the connecting rod 310. This invention's GIL device can adjust the relative position of the housing 20 and the crossbeam 100 simply by adjusting the positions of two fasteners on the connecting rod 310, resulting in higher adjustment efficiency. Furthermore, it avoids open flame operations, reducing sparks and smoke generation, thereby reducing environmental pollution during construction.

[0083] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
