Technical Field
[0001] This utility model relates to the field of cable reel interface technology, specifically a cable reel quick interface device. Background Technology
[0002] During the operation of an electric shovel, its tail line is usually wound and unwound using an auxiliary cable reel. The cable reel is equipped with a cable drum. Since the cable drum is equipped with an electric slip ring, in order for the electric slip ring to work properly, it is necessary to ensure that there is no water vapor inside the drum. This requires the use of a cable drum quick-connect device for connection and sealing.
[0003] However, when using existing cable reel quick-connect devices, it is necessary to open and close the sealed openings such as the cable inlet and manhole on the reel each time the cable wound on the reel is replaced. This process allows outside air to enter the reel. When the air is relatively humid, moisture will be generated as the internal temperature rises, which can easily cause short circuits. It is impossible to replace the connection by simply plugging and unplugging, resulting in poor sealing effect. Utility Model Content

[0050] The present invention will be further described below with reference to the accompanying drawings:
[0051] This embodiment:
[0052] Please see Figure 1-9 In this embodiment, the cable reel quick interface device includes: a plug assembly, a connecting pipe 4, a seal 5, and a docking assembly.
[0053] In this embodiment, the plug assembly consists of a middle plug 1, a rear plug 2, and a front plug 3. The two ends of the middle plug 1 are fixedly connected to the rear plug 2 and the front plug 3, respectively. The connecting tube 4 passes through the front plug 3 and is slidably connected to the front plug 3, so that the cable can pass through the connecting tube 4 and be connected to the cable in the middle plug 1.
[0054] In this embodiment, one set of cables passes through the plug back seat 2 and enters the plug middle seat 1, while another set of cables passes through the connecting pipe 4 and enters the plug middle seat 1, thus connecting the two sets of cables; the connection is made by plugging and unplugging the connecting pipe 4.
[0055] The outer side of the seal 5 is fixedly connected to the inner wall of the connecting pipe 4 to seal the gap between the cable and the connecting pipe 4.
[0056] In this embodiment, the seal 5 is made of rubber material and can be used for sealing.
[0057] The docking assembly is connected to the front of the plug 3; the docking assembly includes a docking piece 8, which is sleeved on the outside of the front of the plug 3 and fits against the middle of the plug 1, for docking and fixing the cable.
[0058] In this embodiment, by operating the docking assembly, the docking assembly will fix the docking part 8 and the plug middle seat 1. Since the docking part 8 is located between the plug middle seat 1 and the socket front seat 7 and is made of rubber material, it can be sealed. At the same time, since the cable replacement is located on the outside of the reel, it is not necessary to open the reel during the replacement process, thus preventing moisture from entering the reel and improving the sealing effect.
[0059] like Figure 5 As shown, the edge of the mating part 8 is provided with multiple sets of snap-fit blocks.
[0060] like Figure 3 and Figure 4 As shown, the docking assembly includes: a socket rear seat 6, a socket front seat 7, multiple sets of support members 9, a rotating member 10, a fixing member 11, and multiple sets of limiting members 12.
[0061] Specifically, the socket back seat 6 is fitted onto the outside of the connecting pipe 4 and is fixedly connected to the connecting pipe 4; the socket front seat 7 is fixedly connected to the end of the socket back seat 6 near the plug front seat 3.
[0062] In this embodiment, the plug front socket 3 is inserted into the socket front socket 7, and the connecting tube 4 connected to the socket rear socket 6 is inserted into the plug front socket 3.
[0063] Multiple sets of support members 9 are all located on the outside of the socket front seat 7 and are fixedly connected to the socket front seat 7; a notch is opened on the outside of the support member 9; a rotating member 10 is located in the notch and the axis of the rotating member 10 is rotatably connected to the support member 9.
[0064] In this embodiment, the rotating member 10 can rotate along the connection with the support member 9.
[0065] The fixing member 11 consists of a first rod and a second rod. One end of the first rod is fixedly connected to one end of the second rod. The first rod is set in the snap-fit block and is slidably connected to the mating member 8. The other end of the first rod is fixedly connected to the edge of the rotating member 10.
[0066] In this embodiment, by rotating the fixing member 11, the fixing member 11 can drive the rotating member 10 to rotate, and the first rod rotates into the snap-fit block. This process will squeeze the docking member 8. Since the thickness of the second rod is twice that of the first rod and is larger than the snap-fit interface size of the snap-fit block, the docking member 8 is restricted to prevent the docking member 8 from separating from the socket front seat 7.
[0067] Each set of limiting members 12 is disposed between two adjacent sets of locking blocks, and is slidably connected to the docking member 8 through a groove formed on the docking member 8.
[0068] During docking, the plug middle seat 1 and the socket front seat 7 work together to clamp the docking piece 8 in the middle. Then, the fixing part 11 is rotated, which will drive the rotating part 10 to rotate along the connection with the support part 9. This process will compress the docking piece 8. Since the thickness of the second rod is twice that of the first rod and is larger than the size of the snap-fit interface of the snap-fit block, the docking piece 8 is restricted to prevent it from separating from the socket front seat 7. This replacement process is located on the outside of the drum, thus avoiding the need to open the drum during the replacement process, preventing moisture from entering the drum, and improving the sealing effect.
[0069] After the docking is completed, since the fastener 11 and the docking part 8 are only restricted by friction, they are prone to falling off due to movement.
[0070] To address the aforementioned issues, this embodiment proposes an implementation method in which the cable reel quick-connect device further includes an anti-movement structure; the anti-movement structure is disposed on the outside of the socket back seat 6 to prevent the fixing member 11 from moving.
[0071] like Figure 6 and Figure 9 As shown, the anti-movement structure includes: a gear ring 13, multiple sets of spur gears 14, a support assembly, a moving ring 16, multiple sets of threaded rods 15, multiple sets of connecting rods 17, and multiple sets of positioning components 18.
[0072] Among them, the toothed ring 13 is fitted on the outside of the socket back seat 6.
[0073] In this embodiment, multiple sets of meshing teeth are provided on the inner wall of the toothed ring 13.
[0074] Multiple sets of spur gears 14 are disposed on the inner side of the gear ring 13 and mesh with the gear ring 13; the support assembly is connected to the spur gears 14 and is used to support the rotation of the spur gears 14.
[0075] In this embodiment, when the gear ring 13 rotates, it will drive multiple sets of spur gears 14 to rotate simultaneously, and the rotation direction of the multiple sets of spur gears 14 is the same; while the support component will support the rotation of the spur gears 14.
[0076] The movable ring 16 is arranged parallel to the gear ring 13; one end of each set of threaded rods 15 is fixedly connected to the shaft of the spur gear 14; the other end of the threaded rod 15 passes through the movable ring 16 and is threadedly connected to the movable ring 16.
[0077] In this embodiment, when the threaded rod 15 rotates, the moving ring 16 will move horizontally.
[0078] One end of each connecting rod 17 is fixedly connected to the side of the moving ring 16 away from the toothed ring 13; one side of each positioning member 18 is fixedly connected to the other end of the connecting rod 17.
[0079] In this embodiment, the moving ring 16 can drive the positioning member 18 to move via the connecting rod 17.
[0080] like Figure 6 As shown, the positioning member 18 has a through hole at the position corresponding to the fixing member 11, so that the positioning member 18 can be fitted onto the fixing member 11.
[0081] In this embodiment, the movement of the fixing member 11 is restricted by fitting the through hole on the positioning member 18 onto the fixing member 11.
[0082] After the docking is completed, by rotating the gear ring 13, the gear ring 13 will cause multiple sets of spur gears 14 to rotate synchronously, and the spur gears 14 will simultaneously drive the threaded rod 15 to rotate; the threaded rod 15 will cause the moving ring 16 to move towards the gear ring 13, and the gear ring 13 will drive the positioning member 18 to move through the connecting rod 17; so that the through hole on the positioning member 18 is fitted onto the fixing member 11 to restrict the movement of the fixing member 11 and prevent the fixing member 11 from falling off.
[0083] like Figure 9 As shown, two sets of annular grooves are provided on both sides of the spur gear 14.
[0084] like Figure 6 and Figure 9 As shown, each set of support components includes: multiple sets of sliders 19, multiple sets of support rings 20, and multiple sets of connectors 21.
[0085] Specifically, each set of sliders 19 is set in an annular groove, and the sliders 19 are slidably connected to the spur gear 14 through the annular groove.
[0086] In this embodiment, when the spur gear 14 rotates, it will drive the annular slide groove to rotate. The annular slide groove will rotate along the position of the slider 19, thereby using the slider 19 to support the rotation of the spur gear 14.
[0087] Each set of support rings 20 is fixedly connected to the slider 19 on the side near the spur gear 14; each set of connectors 21 is disposed between two adjacent sets of support rings 20 and is fixedly connected to the support rings 20.
[0088] In this embodiment, multiple sets of sliders 19 can be fixed by the support ring 20 and the connector 21; the support ring 20 is fixedly connected to the socket back seat 6.
[0089] The cable reel quick-connect device also includes: a limiting structure; the limiting structure is connected to the toothed ring 13 and is used to limit the rotational position of the toothed ring 13.
[0090] like Figure 7 and Figure 8 As shown, the limiting structure includes: a snap-fit member 22, two sets of pins 23, and two sets of elastic members 24.
[0091] The snap-fit component 22 is located on the inner side of the toothed ring 13 and fits against the toothed ring 13.
[0092] In this embodiment, the rotation of the gear ring 13 is restricted by making the snap-fit member 22 fit against the gear ring 13.
[0093] Each set of pins 23 consists of a horizontal plate and a through rod. One side of the horizontal plate is fixedly connected to the snap-fit member 22. The through rod passes through the horizontal plate and is slidably connected to the horizontal plate. One end of the through rod is fixedly connected to the connector 21. Each set of elastic members 24 is disposed between the horizontal plate and the connector 21 and is sleeved on the outside of the through rod.
[0094] In this embodiment, by pressing down on the horizontal plate, the horizontal plate slides vertically along the outer wall of the through rod, and drives the snap-fit 22 away from the toothed ring 13. During this process, the elastic element 24 is compressed; the elastic element 24 is a spring.
[0095] Working principle:
[0096] When using this cable reel quick-connect device, the plug front seat 3 is inserted into the socket front seat 7, and the connecting tube 4, which is connected to the socket rear seat 6, is inserted into the plug front seat 3, so that the cable in the connecting tube 4 is connected to the cable in the plug middle seat 1. At this time, the plug middle seat 1 and the socket front seat 7 work together to clamp the connecting piece 8 in the middle. Then, the fixing part 11 is rotated, which will drive the rotating part 10 to rotate along the connection with the support part 9. This process will squeeze the connecting piece 8. Since the thickness of the second rod is twice that of the first rod and is larger than the snap-fit interface size of the snap-fit block, the connecting piece 8 is restricted, preventing the connecting piece 8 from separating from the socket front seat 7. This replacement process is located on the outside of the reel, thus avoiding the need to open the reel during the replacement process, preventing moisture from entering the reel, and improving the sealing effect.
[0097] After the docking is completed, the user presses down on the horizontal plate, causing the horizontal plate to slide vertically along the outer wall of the through rod, and moving the snap-fit 22 away from the toothed ring 13. During this process, the elastic element 24 is compressed.
[0098] Then, by rotating the gear ring 13, the gear ring 13 will cause multiple sets of spur gears 14 to rotate synchronously, and the spur gears 14 will simultaneously drive the threaded rod 15 to rotate; the threaded rod 15 will cause the moving ring 16 to move towards the gear ring 13, and the gear ring 13 will drive the positioning member 18 to move through the connecting rod 17; so that the through hole on the positioning member 18 is fitted onto the fixing member 11 to restrict the movement on the fixing member 11 and prevent the fixing member 11 from falling off.
[0099] When the spur gear 14 rotates, it will drive the annular slide groove to rotate. The annular slide groove will rotate along the position of the slider 19, thereby using the slider 19 to support the rotation of the spur gear 14. At the same time, multiple sets of sliders 19 can be fixed by the support ring 20 and the connector 21 to improve the support capacity.
[0100] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
