In one embodiment, the driving assembly 40 includes a driving housing 42, a driving main body 43 and a driving end 41, the driving main body 43 is placed inside the driving housing 42, and the driving end 41 is arranged on the driving main body 43 and exposed from the driving housing 42 outside; the reel assembly 30 includes a reel body 32, the reel cavity 31 is located inside the reel body 32; the drive housing 42 is fixedly mounted on the frame 20, and the reel body 32 is sleeved on the drive housing 42 , and is rotatably connected with the drive housing 42 .

Specifically, the driving housing 42 is disposed outside the driving body 43 , and the driving body 43 drives the driving end 41 to rotate, and then outputs the power of the driving body 43 .

By adopting the above-mentioned technical scheme, the driving housing 42 is used to be fixed on the frame 20 to maintain the stability of the driving main body 43. The driving main body 43 is accommodated in the inside of the driving housing 42 to improve the protection of the driving main body 43.

Specifically, the cables of the lifting device 100 are sequentially wound on the outer surface of the drum body 32 layer by layer, and the drum boards 33 are placed on both sides of the drum body 32, specifically on both sides of the drum body 32. , the cables are wound on the outer surface of the reel body 32 from one side end to the other side end of the reel body 32 in sequence. Continue to wind on the layer cable, from the other side end to one side end in turn, until the cable winds the multi-layer cable on the drum body 32; during this process, the cable may be pulled from the drum body 32, and the unrestricted cable may also cause the cable to be wound irregularly, which is not conducive to recycling and releasing the cable.

By adopting the above technical solution, the reel plate 33 is placed on both sides of the reel body 32, and the outer diameter of the reel plate 33 is larger than the outer diameter of the reel body 32, and the reel plate 33 and the reel body 32 are arranged coaxially , the reel plate 33 rotates with the rotation of the reel body 32, and when the reel body 32 winds or releases the cable, the cable is restricted on the reel body 32 to prevent the cable from falling off from the reel body 32, It makes the cables neatly arranged when winding or releasing, which is convenient for laying out the test equipment.

In one embodiment, the reel assembly 30 further includes a tooth row structure 34 arranged on the reel plate 33, the tooth row structure 34 is arranged along the circumferential direction of the reel plate 33, and the outer diameter of the tooth row structure 34 is larger than that of the reel The outer diameter of the main body 32 is also rotated on the frame 20 to be provided with a manual rocker (handle 14), and the manual rocker (handle 14) is provided with gears for transmission and cooperation with the tooth row structure 34, and the gears here all correspond to the above-mentioned automatic gear 12. It should be noted that the tooth row structure 34 is arranged along the circumferential direction of the reel plate 33 to form the structure of the manual gear 13 .

Specifically, when the drive assembly 40 loses power or breaks down, it is necessary to manually adjust the reel assembly 30. At this time, the user can operate the manual rocker (handle 14) to drive the gear on the manual rocker (handle 14) ( The automatic gear 12) rotates around itself, and the gear (automatic gear 12) meshes with the gear row structure 34, and the rotation of the gear (automatic gear 12) drives the gear row structure 34 to rotate, and then drives the reel plate 33 to rotate, and then drives the reel main body 32 to rotate, and finally drive the retraction or release of the cable.

It should be further explained that the outer diameter of the tooth row structure 34 is larger than the outer diameter of the reel body 32, while the outer diameter of the gear (automatic gear 12) is much smaller than the outer diameter of the tooth row structure 34, thus increasing the size of the reel body 32. The torque makes the user turn the manual rocker with a small force to drive the reel main body 32, and then rotate the reel main body 32. The manual rocker here is the handle 14.

In one embodiment, the lifting device 100 also includes a one-way bearing 50 (reverse slipping device, which cooperates with the reducer and brake to prevent the equipment from slipping when the motor is out of control) arranged between the reel assembly 30 and the drive assembly 40. The direction bearing 50 includes an inner ring 51 disposed on the driving end 41 and an outer ring 52 disposed on the reel plate 33 , and the inner ring 51 can rotate unidirectionally relative to the outer ring 52 in a predetermined direction.

Specifically, the inner ring 51 rotates in one direction relative to the preset direction, that is, the inner ring 51 rotates clockwise or counterclockwise in one direction relative to the outer ring 52; as shown in FIG. 14 , in general, the drive assembly 40 can During normal use, if the cable needs to be recovered and wound to the reel main body 32, the drive assembly 40 is activated, and the drive end 41 of the drive assembly 40 rotates in the direction shown by R1 in the figure, that is, the drive end 41 of the drive assembly 40 rotates along the Rotate in the preset direction, and drive the inner ring 51 of the one-way bearing 50 to rotate synchronously in the R1 direction, and the inner ring 51 acts on the outer ring 52 in the R1 direction, because the outer ring 52 of the one-way bearing 50 can only rotate in the R1 direction Rotating relative to the inner ring 51 , at this time, the driving end 41 of the driving assembly 40 can drive the one-way bearing 50 to rotate synchronously along the R1 direction, thereby driving the reel main body 32 to rotate along the R1 direction, and recover the cable.

As shown in Figure 15, on the contrary, the driving assembly 40 can be used normally, and the cable wound on the drum body 32 needs to be released. As shown in the figure, the driving assembly 40 is started, and the driving end 41 of the driving assembly 40 is along the Rotate in the direction indicated by R2, that is, rotate in the direction opposite to the preset direction, and drive the inner ring 51 of the one-way bearing 50 to rotate synchronously in the R2 direction, and the inner ring 51 acts on the outer ring 52 to act in the R2 direction. The outer ring 52 of the one-way bearing 50 can only rotate relative to the inner ring 51 along the R1 direction. At this time, the driving end 41 of the driving assembly 40 can drive the one-way bearing 50 to rotate synchronously along the R2 direction, thereby driving the reel main body 32 along the R2 direction. direction, and release the cable wound on the reel main body 32 .

As shown in FIG. 16 , in an emergency, the drive assembly 40 cannot be powered on normally, that is, the drive assembly 40 is powered off, and the driving end 41 of the drive assembly 40 cannot rotate, so that the reel main body 32 cannot be driven to rotate through the drive assembly 40. At this time, when the cable needs to be recovered, the operator drives the manual rocker (handle 14) to rotate, and the manual rocker (handle 14) rotates and acts on the outer ring 52 of the one-way bearing 50 to rotate in the direction shown by R1 in the figure. Force, that is, the force that provides the outer ring 52 of the one-way bearing 50 to rotate relative to the inner ring 51 in a preset direction. Since the outer ring 52 of the one-way bearing 50 can rotate relative to the inner ring 51 in the R1 direction, it can be passed through a single The outer ring 52 of the bearing 50 drives the reel main body 32 to rotate synchronously in the R1 direction, and recovers the cable. And, in this driving process, since the driving end 41 of the driving assembly 40 does not rotate, that is, the inner ring 51 of the one-way bearing 50 does not rotate, the driving end 41 of the driving assembly 40 will not have any influence on the rotation of the one-way bearing 50 , which can ensure the one-way rotation of the outer ring 52 of the one-way bearing 50 along the preset direction.

By adopting the above technical solution, the one-way bearing 50 limits the rotation direction of the inner ring 51 relative to the outer ring 52, ensuring that the reel main body 32 can still be rotated by the manual rocker (handle 14) in the event of a power failure of the drive assembly 40 , ensuring the availability of the lifting device 100 in various situations, and reducing the impact of the failure of the drive assembly 40 on the work tasks.

When the reel body 32 releases or recovers the cable, the cable discharge mechanism 63 synchronously moves along the axis parallel to the reel body 32. The direction of reciprocating movement, the following will be described through the process of recovering the cables: the cables of the lifting device 100 are wound on the outer surface of the reel main body 32 layer by layer, and the cables are sequentially released from One side end of the reel main body 32 is wound on the outer surface of the reel main body 32 toward the other side end. After the first layer of cables of the reel main body 32 is wound, the cables continue on the first layer of cables. Winding, the cables are wound sequentially from the other side end to one side end under the guidance of the cable unwinding mechanism 63 until the cables are wound with multiple layers of cables on the reel main body 32 .
