DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] An embodiment of the present application provides a cable entry fixing assembly.

[0021] In one embodiment, referring to Figure 1 , Figure 1 This is a structural diagram of an embodiment of the combined function lifting system of this application. Figure 1 As shown, the combined function lifting system includes at least one sling unit, which includes: a rotatable base 1, a sling structure body 2, a sling mechanism 3 and a sling extension structure 4.

[0022] The sling structure body 2 is fixed on the rotatable base 1 ; the sling mechanism 3 is provided on the sling structure body 2 ; the sling extension structure 4 is provided on the sling structure body 2 , and the sling extension structure 4 is used to connect another sling unit.

[0023] Thus, the hoisting angle can be conveniently adjusted through the rotatable base 1, and more hoisting units can be connected through the hoist extension structure 4. The hoisting combination can be performed according to the situation of the hoisted sample 100, and the hoisting and installation of the sample 100 can be completed quickly and efficiently.

[0024] The following is an introduction to the various combinations of combined functional lifting systems: One sling per spreader unit: See also Figure 1 As shown, the sling mechanism 3 includes a winch 31, a pulley block 32, and a sling 33. The winch 31 is fixed to the sling structure body 2; the pulley block 32 is fixed to the sling structure body 2; one end of the sling 33 is wound around the winch 31, and the other end is wound around the pulley block 32 and then passed out.

[0025] The sling structure 2 uses a four-bar linkage to move the sample. The sling 33 on the winch 31 changes direction through a pulley block 32. The pulley block is placed on the sling structure 2. When the winch 31 is rotated clockwise or counterclockwise, the sling 33 can be raised or lowered.

[0026] The rotatable base 1 is also equipped with a clamping base 11. One end of the rotatable base 1 is connected to the sling structure 2, and the other end is connected to the clamping base 11. The clamping base 11 can be connected to the test table and fixed to the tabletop via a locking handle 12. When the rotatable base 1 is rotated, the rotatable base 1 drives the sling structure 2 to achieve a 360° rotation.

[0027] Two spreader units with two slings, both fixed slings: See also Figure 2 and Figure 3 As shown, the spreader extension structure 4 includes a stopper 41 with connecting bolts 42 mounted thereon. The stopper 41 and connecting bolts 42 function to combine the spreaders and, in conjunction with the connecting rod 5, connect the two spreader units. Specifically, the upper end of the connecting rod 5 is limited by the stopper 41, and the lower end is secured by the connecting bolts 42, thereby combining the two separate spreader units into a single, rigid spreader.

[0028] Two fixed lifting blocks 6 are provided on the connecting rod 5 , and the sling mechanisms 3 of the two sling units each include a winch 31 , a pulley block 32 and a sling 33 .

[0029] The winch 31 is fixed on the sling structure body 2; part of the pulleys of the pulley set 32 are fixed on the sling structure body 2, and the other part of the pulleys are fixed on one of the fixed lifting blocks 6; one end of the sling 33 is wrapped around the winch 31, and the other end is wrapped around the pulleys on the sling structure body 2 and the fixed lifting block 6, and passes through the pulley on the fixed lifting block 6.

[0030] There is a square hole on the fixed hanging block 6, which can move along the connecting rod 5; the sling 33 changes its direction through the pulley set 32 and is connected to the fixed hanging block 6; the locking handwheel 61 is placed on the fixed hanging block 6, and when it is in the locked state, the fixed hanging block 6 will not move relative to the connecting rod 5; by rotating the winch 31 clockwise or counterclockwise synchronously, the sample 100 hoisted by the sling 33 will move up or down.

[0031] In this case, the structures of the two sling units are consistent, the slings 33 are fixed slings and cannot be adjusted, and the arrangement of the winch 31, pulley block 32 and sling 33 of the two is also the same. By combining the two sling units together, the sample can be lifted more stably.

[0032] Two spreader units with two slings, one fixed and one movable: See also Figures 4 to 7 As shown, compared with the case where both slings are fixed, the main difference between the two sling units is the arrangement of the slings. The structures are still roughly similar. To distinguish them, the identification of the sling mechanisms 3 of the two are distinguished.

[0033] Specifically, the two sling units are connected by a connecting rod 5 via the sling extension structure 4. The connecting rod 5 is provided with a fixed sling block 6 and an adjustable sling block 7. The adjustable sling block 7 is provided with a slide rail groove, and the slide rail groove is provided with a telescopic assembly 8. Preferably, the adjustable sling block 7 is also provided with a first counterweight block 71.

[0034] The sling mechanism 3 of one of the spreader units includes a first winch 31 a , a first pulley block 32 a and a first sling 33 a .

[0035] Among them, the first winch 31a is fixed on the sling structure body 2; part of the pulleys of the first pulley group 32a are fixed on the sling structure body 2, and the other part of the pulleys are fixed on the fixed lifting block 6; one end of the first sling 33a is wrapped around the winch 31a, and the other end is wrapped around the pulleys on the sling structure body 2 and the fixed lifting block 6, and passes through the pulley on the fixed lifting block 6.

[0036] The sling mechanism 3 of the other sling unit includes a second winch 31b, a second pulley block 32b and a second sling 33b.

[0037] Among them, the second winch 31b is fixed on the sling structure body 2; part of the pulleys of the second pulley group 32b are fixed on the sling structure body 2, and the other part of the pulleys are arranged on the slide rail groove of the adjustable lifting block 7 and are connected to the telescopic assembly 8; one end of the second sling 33b is wrapped around the winch 31, and the other end is wrapped around the pulleys on the sling structure body 2 and the adjustable lifting block 7, and passes through the pulley on the adjustable lifting block 7.

[0038] In this embodiment, the telescopic assembly 8 includes a support block 81 , a lead screw 82 and a nut sleeve 83 .

[0039] Among them, the support block 81 is fixed on the adjustable hanging block 7; one end of the screw 82 is connected to the support block 81; the nut sleeve 83 is connected to the other end of the screw 82 and fixed on the pulley on the adjustable hanging block 7.

[0040] It is worth noting that the pulley arranged on the slide rail groove of the adjustable hanging block 7 is the movable pulley 32b1, and the movable pulley 32b1 and the support block 81 are placed in the slide rail groove on the adjustable hanging block 7; the movable pulley 32b1 and the nut sleeve 83 are a whole; when the screw 82 is fixed by the support block 81 and the screw 82 moves clockwise or counterclockwise relative to the nut sleeve 83, the movable pulley 32b1 can move back and forth, and synchronously drive the second sling 33b to move back and forth, so that samples with more complex and irregular shapes can be hoisted.

[0041] Two spreader units with three slings, one fixed sling, one movable sling, and one movable and rotating sling: It can be understood that this situation is equivalent to adding a movable and rotatable sling to the previous situation.

[0042] See also Figure 8 As shown, in this case, there is an additional mobile rotating hanger 9, which includes a rotating mechanism and a sliding lifting mechanism. The rotating mechanism is rotatably fixed on the adjustable lifting block 7, and the sliding lifting mechanism is connected to the rotating mechanism and can slide relative to the rotating mechanism.

[0043] See also Figure 9 Specifically, the rotating mechanism includes a fixed portion and a turntable 91. The fixed portion is connected to the adjustable lifting block 7, and the turntable 91 is connected to the fixed portion and can rotate relative to the fixed portion. The sliding lifting mechanism includes a slide rail 92, a third winch 93, a third pulley set 94, and a third lifting rope 95.

[0044] Among them, the slide rail 92 is arranged at the bottom end of the turntable 91 and can move relative to the turntable 91; the third winch 93 is fixed on the slide rail 92; the third pulley group 94 is fixed on the slide rail 92; one end of the third sling 95 is wrapped around the third winch 93, and the other end is wrapped around the third pulley group 94 and then passes out.

[0045] The turntable locking wheel 96 is used to lock the turntable 91 to limit its rotation after it is rotated into place; the movable locking wheel 97 provided on the fixed part is used to lock the turntable 91 and the adjustable hanging block 7 to limit the relative movement between the two; in addition, the turntable 91 can also move relative to the adjustable hanging block 7 to adjust the fixed position.

[0046] The winch support 98, the third winch 93, the third pulley set 94, and the second counterweight block 99 placed on the slide rail 91 can all be driven by the turntable 91 to rotate 360°; when the third winch 93 rotates clockwise or counterclockwise, the third sling 95 will move up and down.

[0047] See also Figure 10 and Figure 11 As shown, they are schematic diagrams of the turntable 91 driving the slide rail 92 to rotate 90° and 0° respectively; wherein, the first sling 33a is fixed, the second sling 33b is movable, and the third sling 95 can be both movable and rotatable; this combination can be used to lift samples 100 with unstable center of gravity that require angular deflection during installation.

[0048] See also Figure 12 The figure shows how the lifting unit is positioned on different test tables, meeting test preparation requirements of varying standards. Lifting is performed under an EMC (Electro Magnetic Compatibility) environment. The lifting unit's clamping base 11 also includes a grounded copper busbar that contacts the test table for a common ground connection. The grounding resistance requirement is very low, requiring connection to the copper plate on the tabletop to achieve EMC grounding resistance. Furthermore, the different test tables are connected via copper busbars, forming a single grounded entity, ensuring low grounding resistance during testing.

[0049] In summary, the combined functional lifting system of the present application includes at least one sling unit, which includes: a rotatable base; a sling structure body fixed to the rotatable base; a sling mechanism disposed on the sling structure body; and a sling extension structure disposed on the sling structure body, the sling extension structure being used to connect to another sling unit. Thus, the rotatable base allows for convenient adjustment of the lifting angle, and the sling extension structure allows for connection of more sling units, allowing for the lifting combination to be performed according to the sample being hoisted, enabling the lifting and installation of the sample to be completed quickly and efficiently.
