Description

Technical Field

[0001] This utility model relates to an automatic cable retraction and deployment device, which is relevant to the field of power supply for mobile mechanical equipment. Background Technology

[0002] In emergency rescue and material handling, specialized mobile machinery requires electric power. To avoid increasing the size and weight of the equipment, it is often powered by a towed cable. This includes various large rescue robots and electric flatcars with cable reels. Taking the hydraulically powered drainage robot, widely used in emergency rescue, as an example, to reduce its size and weight, it often adopts a mother-daughter vehicle configuration, with power supplied by the mother vehicle via a cable. The mother vehicle is equipped with a cable reel; when the robot moves forward to work, the cable is released; after the operation is completed, the cable is simultaneously retracted when the robot is retrieved.

[0003] Existing cable winding and unwinding devices, in their traditional form, require manual operation of the reel, which is time-consuming and labor-intensive. Some electric cable reels in use also require motor control for both winding and unwinding, increasing energy consumption and motor wear. Furthermore, most existing cable reels lack cable routing mechanisms, easily leading to localized stacking or messy crossing during winding. Severe localized stacking can cause excessive pressure on the cable, accelerating insulation aging and wasting space; messy crossings can easily cause cable knots, potentially leading to cable breakage. Utility Model Content

[0004] To address the above problems, this utility model proposes an automatic cable reeling and unloading device that can efficiently complete the electric reeling and unloading of cables, and can achieve good cable routing, avoiding damage to the cables.

[0005] The technical solution of this utility model is as follows: it includes a main support 1, a reel assembly 4 for winding cables, an electrical power input assembly 5 for receiving external electrical energy or signals, and a reel drive wheel assembly 3 for receiving a rotating power source. The power access component 5 includes a plug and socket assembly 51, a fixed shaft assembly 52, a slip ring 53, and a transition flange 54. The plug and socket assembly 51 is fixedly mounted on the main support 1 via the fixed shaft assembly 52 and is used to receive external power or signals. The stator of the slip ring 53 is fixedly mounted on the fixed shaft assembly 52, and the rotor of the slip ring 53 is rotatably inserted into the stator and fixedly connected to the transition flange 54. The reel assembly 4 includes a drive-side reel plate 41, a driven-side reel plate 42 arranged side by side, and a plurality of support round tube assemblies 43 fixedly installed between the two. The driven-side reel plate 42 is rotatably mounted on the fixed shaft assembly 52, and the drive-side reel plate 41 is fixedly connected to the transition flange 54. The reel drive wheel assembly 3 includes a drive spindle 31, an electromagnetic clutch 32, a large gear 33, and a drive wheel plate 34. The drive spindle 31 is fixedly mounted on the drive-side reel plate 41 and is coaxially arranged with the fixed shaft assembly 52. ​​The drive spindle 31 can also rotatably pass through the main support 1. The electromagnetic clutch 32 is mounted on the drive spindle 31, and the drive wheel plate 34 is mounted on the electromagnetic clutch 32. The electromagnetic clutch 32 is disengaged when de-energized and engaged when energized. The large gear 33 is fixedly mounted on the drive wheel plate 34 and is used to receive the rotational power source and transmit it to the drive spindle 31 and the reel assembly 4 via the electromagnetic clutch 32.

[0006] Furthermore, the fixed shaft assembly 52 is hollow and is used to insert a wire that provides external power or signal; one end of it is fixed to the side of the main bracket 1, and the other end is fixedly connected to the stator of the slip ring 53, and the wire is kept in communication with the stator of the slip ring 53. The transition flange 54 consists of two flanges and a circular tube with an opening in the side wall. One flange is fixedly connected to the flange on the rotor of the slip ring 53, and the other flange is coaxially fixedly connected to the drive-side reel plate 41. The end of the cable passes through the opening in the side wall of the circular tube and remains in communication with the rotor of the slip ring 53.

[0007] Furthermore, the reel assembly 4 also includes a seated bearing 44 fixedly mounted on the driven side reel plate 42, the seated bearing 44 being rotatably mounted on the fixed shaft assembly 52.

[0008] Furthermore, the automatic cable reeling device also includes a motor assembly 2 as a rotational power source. The motor assembly 2 includes a motor 21 fixedly mounted on the main support 1 and an output gear 22 mounted on the motor output shaft. The output gear 22 and the large gear 33 are engaged.

[0009] Furthermore, the automatic cable reeling device also includes a cable guide 8 for cable management. The cable guide 8 is mounted above the reel assembly 4 via a secondary bracket 7. The cable guide 8 includes a reciprocating screw assembly 81, a pulley fixing seat 82, and a guide pulley group 83. The reciprocating screw assembly 81 includes a screw seat fixedly mounted on the secondary bracket 7, a reciprocating screw rotatably connected in the screw seat, and a fixed guide rod arranged side by side of the reciprocating screw. The reciprocating screw receives rotational power.

[0010] Furthermore, the drive spindle 31 and the reciprocating lead screw are linked together by the sprocket assembly 6.

[0011] The beneficial effects of this utility model are: 1. This device can be controlled by an electromagnetic clutch. When releasing the cable, the power is off and the electromagnetic clutch is in the open state, so the cable will be pulled out naturally when the electrical equipment is moved. When retracting the cable, the power is on, the electromagnetic clutch is closed, and the motor drives the reel to rotate and retract the cable. The control and operation are simple, the action is reliable, and it saves manpower.

[0012] II. This automatic cable reeling and unloading device is equipped with a cable guide, which has an automatic cable routing function. The cable guide automatically routes the cable during reeling, avoiding local stacking or messy crossing of the cable; during unloading, it also guides the cable, which is released through the pulley system of the cable guide in a basically fixed direction. It will not swing randomly and cause local stacking or crossing, nor will it scratch the edges of structural components and accelerate the wear of the cable insulation.

[0013] Third, the aforementioned cable guide is powered by a drive spindle via chain transmission, eliminating the need for an independent external power source.

[0014] Fourth, since the automatic cable reel-in / reel-out device is energized only when reeling in the cable, it can save energy and reduce mechanical wear on the motor and related transmission devices. Attached Figure Description

[0022] Preferably, the reel drive wheel assembly 3 includes an electromagnetic clutch 32. When unwinding, the electromagnetic clutch 32 is disengaged, and the reel assembly 4 can rotate freely; when rewinding, the electromagnetic clutch 32 is engaged, wherein the active toothed disc is connected to the drive spindle 31 via a flat key, and the driven toothed disc is fixedly connected to the drive wheel plate 34.

[0023] like Figure 1 , 2 As shown in Figure 6, the system also includes a reel assembly 4. The reel assembly consists of a drive-side reel plate 41, a driven-side reel plate 42, a support tube assembly 43, and a seated bearing 44. Both the drive-side reel plate 41 and the driven-side reel plate 42 have openings at their centers and around their perimeters, which are used to pass shafts through and fix the reel assembly 4 and other components, respectively. The support tube assembly 43 has axial threads on both sides inside, which are used to fix the drive-side reel plate 41, the driven-side reel plate 42, and the support tube assembly 43 to the support tube assembly 43 by bolts. There are multiple support tube assemblies 43, which are evenly distributed around the axis of the drive-side reel plate 41 and the driven-side reel plate 42.
