[0039] like Figure 1 As shown, an embodiment of the present invention relates to a hoisting fixture used for hoisting a cable terminal 10, wherein the cable terminal 10 may be a support-type pluggable cable terminal.

[0040] The hoisting equipment includes a base plate 100, lifting rings 200, a limiting plate 300, and lifting straps 400.

[0041] Combination Figure 1 and Figure 2 The base plate 100 is provided with a first clearance hole 110 and a plurality of first mounting holes 120 arranged circumferentially along the first clearance hole 110.

[0042] Specifically, the first clearance hole 110 penetrates the upper and lower sides of the base plate 100, and the first mounting hole 120 also penetrates the upper and lower sides of the base plate 100. There are multiple first mounting holes 120, and the multiple first mounting holes 120 are arranged at intervals along the circumference of the first clearance hole 110.

[0043] There are multiple lifting rings 200, all of which are connected to the base plate 100. The multiple lifting rings 200 are spaced apart circumferentially along the first clearance hole 110, and the lifting rings 200 are set away from the first assembly hole 120.

[0044] It is understandable that the first mounting hole 120 and the lifting ring 200 are offset in the horizontal direction, that is, the lifting ring 200 will not cover the first mounting hole 120.

[0045] Limiting plates 300 are arranged side by side and spaced apart above the base plate 100. Each limiting plate 300 has multiple guide holes 310, which correspond to multiple lifting rings 200.

[0046] Combination Figure 1 , Figure 2 and Figure 3 Specifically, the number of guide holes 310 is the same as the number of lifting rings 200, and a plane perpendicular to the first clearance hole 110 is defined as a reference plane. In each set of corresponding guide holes 310 and lifting rings 200, the projection 310a of the guide hole on the reference plane is located on the side of the projection 200a of the lifting ring on the reference plane that is closer to the axis of the first clearance hole 110, and the distance between the projection 310a of the guide hole on the reference plane and the projection 200a of the lifting ring on the reference plane is S1. In addition, in each set of corresponding guide holes 310 and lifting rings 200, the center line connecting the projection 310a of the guide hole on the reference plane and the projection 200a of the lifting ring on the reference plane intersects the axis of the first clearance hole 110.

[0047] It is understood that in other embodiments, in each set of corresponding guide holes 310 and lifting rings 200, the projection 310a of the guide hole on the reference plane is located on the side of the projection 200a of the lifting ring on the reference plane away from the axis of the first clearance hole 110.

[0048] like Figure 1 As shown, the sling 400 includes multiple hanging sections 410, the bottom ends of which are connected to multiple lifting rings 200, and the multiple hanging sections 410 pass through multiple guide holes 310, and the top ends of the multiple hanging sections 410 are connected to each other.

[0049] It should be noted that each hanging segment 410 can be a rope-like or strip-like structure. The number of hanging segments 410, the number of guide holes 310, and the number of lifting rings 200 are all the same. The bottom ends of multiple hanging segments 410 are connected to multiple lifting rings 200 in a one-to-one correspondence, and multiple hanging segments 410 pass through multiple guide holes 310 in a one-to-one correspondence. The top ends of multiple hanging segments 410 are connected to each other.

[0050] It is understood that in other embodiments, each lifting ring 200 may also connect to two or more sling segments 400, and each guide hole 310 may also allow two or more hanging segments 410 to pass through.

[0051] It should be noted that the lifting fixture also includes a hook 500. The tops of multiple hanging sections 410 are all connected to the hook 500. The hook 500 can be used to connect with a lifting device, which can drive the entire lifting fixture to move up and down. The lifting device can be a crane or other lifting devices.

[0052] In the hoisting fixture of this utility model, the base plate 100 is used to support the cable terminal 10, the first clearance hole 110 is used for the bottom end of the cable terminal 10 to pass through, and the base plate 100 is provided with mounting holes 140 for bolts to pass through, so that the cable terminal 10 can be fixed to the base plate 100 by bolts; the limiting plate 300 is used to support the sling 400 so that the sling 400 avoids the cable terminal 10 and prevents the hanging section 410 from hitting the cable terminal 10; and the top end of the sling 400 can be hung by the lifting device, which can drive the entire hoisting fixture to rise and fall.

[0053] Combination Figure 1 , Figure 2 and Figure 3 Furthermore, the multiple lifting rings 200 are evenly spaced along the circumference of the first clearance hole 110, that is, the projections 200a of the multiple lifting rings on the reference plane are evenly spaced around the axis of the first clearance hole 110, and the projections 310a of the multiple guide holes on the reference plane are evenly spaced around the axis of the first clearance hole 110.

[0054] like Figure 1 As shown, further, the lifting ring 200 includes a connecting portion 210 connected to the base plate 100 and a hanging portion 220 connected to the connecting portion 210. The hanging portion 220 is located above the base plate 100, and the bottom end of the hanging section 410 is connected to the hanging portion 220. The hanging portion 220 is a ring-shaped component, and the hanging section 410 can be inserted through the hanging portion 220 and then knotted to connect with the hanging portion 220.

[0055] Specifically, the base plate 100 is also provided with a plurality of connecting holes 130 that are evenly and spaced apart along the circumference of the first clearance hole 110. That is, the projections of the plurality of connecting holes 130 on the reference plane are evenly spaced around the axis of the first clearance hole 110. The connecting holes 130 penetrate the upper and lower sides of the base plate 100, and the connecting parts 210 of the plurality of lifting rings 200 are correspondingly inserted into the plurality of connecting holes 130.

[0056] In this embodiment, the connecting hole 130 can be a threaded hole, and the connecting part 210 can be a threaded segment with external threads; in other embodiments, the connecting hole 130 can be a normal through hole, and the connecting part 210 is a threaded segment with external threads. After the connecting part 210 passes through the connecting hole 130, it can be fixed by means of bolts.

[0057] like Figure 2 As shown, the base plate 100 is also provided with a through groove 150 communicating with the first clearance hole 110. The through groove 150 penetrates at least one side of the base plate 100. The through groove 150 can avoid the occurrence of induced current and eddy current.

[0058] like Figure 1 As shown, in some embodiments, the limiting plate 300 is provided with a second clearance hole 320 opposite to the first clearance hole 110, and a plurality of guide holes 310 are arranged at circumferential intervals along the second clearance hole 320.

[0059] It is understandable that the second clearance hole 320 can allow the connecting hardware 40 on the upper part of the cable terminal 10 to pass through. Of course, in other embodiments, the limiting plate 300 may not be provided with the second clearance hole 320, and the limiting plate 300 can be set above the connecting hardware 40.

[0060] like Figure 1 As shown, in some embodiments, a connecting component 600 is also connected to the bottom of the base plate 100. The connecting component 600 is used to connect to the cable 20 connected to the cable terminal 10.

[0061] Understandably, by connecting the cable 20 via the connecting component 600, the stability between the cable 20 and the base plate 100 can be further maintained.

[0062] Specifically, the connecting assembly 600 includes a first connector 610 connected to the lower part of the base plate 100 and a second connector 620 connected to the first connector 610, wherein the second connector 620 is used to connect to the cable fixing clip 30 sleeved on the cable 20.

[0063] The first connector 610 can be fixed to the base plate 100 by welding or threaded connection, the second connector 620 can be fixed to the first connector 610 by welding or threaded connection, and the second connector 620 can be fixed to the cable clamp 30 by welding or threaded connection.

[0064] Furthermore, the vertical mounting position of the second connector 620 on the first connector 610 is adjustable.

[0065] Specifically, before fixing the second connector 620 to the first connector 610, the installation position of the second connector 620 can be determined by the position of the cable fixing clip 30 to ensure that the second connector 620 and the cable fixing clip 30 can be connected together.

[0066] It should be noted that the terminal tower has a bracket 50, the bracket 50 has a support plate 51, the support plate 51 has a plurality of second mounting holes, and the plurality of second mounting holes correspond one-to-one with the plurality of first mounting holes 120. That is, the base plate 100 can be set on the support plate 51, and the plurality of first mounting holes 120 and the plurality of second mounting holes are arranged opposite each other one-to-one. Then, bolts can be passed through the first mounting holes 120 and the second mounting holes, and then nuts can be used to fix the base plate 100 to the support plate 51.

[0067] It should be noted that the lifting ring 200 is detachably connected to the base plate 100. Thus, the lifting ring 200, lifting strap 400, limiting plate 300, and other structures can all be removed from the base plate 100. Once the cable terminal 10 is installed in place and the base plate 100 is fixed to the support 50 of the terminal tower, the lifting ring 200, lifting strap 400, limiting plate 300, and other structures can be removed from the base plate 100 to prevent them from affecting the normal operation of the cable terminal 10.

[0068] The specific usage of this hoisting fixture is as follows:

[0069] S100, insert the cable terminal 10 into the first clearance hole 110 of the base plate 100 from top to bottom, and then fix the cable terminal 10 on the base plate 100. The base plate 100 is pre-installed with a lifting ring 200 and pre-fixed with a connecting component 600.

[0070] S200, fix the base plate 100 to the ground support frame to maintain the stability of subsequent installation. Of course, step S200 can be omitted in some cases.

[0071] S300, the cable 20 is passed through the cable terminal 10 from below to complete the assembly of the cable 20 and the cable terminal 10.

[0072] S400, weld the cable clamp 30 onto the cable 20, and then weld the connecting assembly 600 to the cable clamp 30;

[0073] S500, a limiting plate 300 is installed on the top of the cable terminal 10;

[0074] S600, the hanging sections 410 of the sling 400 with hooks 500 are passed through the guide holes 310 on the limiting plate 300, and then the bottom end of each hanging section 410 is connected to each lifting ring 200.

[0075] S700, hook 500 is hung on the lifting device, and then the lifting device is used to lift the entire system to the terminal tower, so that the base plate 100 is placed on the support plate 51 of the support 50 of the terminal tower.

[0076] S800, so that the first mounting hole 120 on the base plate 100 is aligned with the second mounting hole on the support plate 51, and then the base plate 100 is fixed to the bracket using bolts and nuts.

[0077] S900, remove the lifting ring 200, lifting strap 400, limit plate 300 and other structures from the base plate 100.

[0078] It should be noted that the order of steps S100-S600 can be adjusted without affecting the assembly. For example, in step S100, the lifting ring 200 and the connecting component 600 may not be pre-set on the base plate 100, but may be done in a later step. For example, in S600, the step of installing the lifting strap 400 can also be adjusted, as long as it does not affect the final assembly effect.

[0079] The hoisting fixture of this utility model can be connected to the cable terminal 10 on the ground and then lifted by the hoisting device onto the support plate 51 of the support 50 of the terminal tower. The base plate 100 of the hoisting fixture can be directly fixed to the support plate 51 without the need to remove the base plate 100. After the base plate 100 is fixed, the lifting ring 200, lifting strap 400, limiting plate 300 and other structures can be removed from the base plate 100. During the disassembly process, since the base plate 100 is fixed to the support plate 51, that is, the cable terminal 10 is in a fixed state, the entire disassembly process is more convenient.
