[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] See Figures 1-4 The winding device 100 of this embodiment includes a bracket 1, a winding drum 2, a cable assembly 3, and a drive assembly.

[0025] The bracket 1 can be supported on the ground or placed on other equipment, such as a transport trolley or work platform, for easy movement. The shaft of the drum 2 is rotatably connected to the bracket 1. The drum 2 has a cable storage slot 21. Cables, such as electrical cables, air hoses, and liquid hoses, can be coiled in the cable storage slot 21.

[0026] The cable routing assembly 3 is connected to the bracket 1 and is located on one side of the drum 2. The cable in the cable storage slot 21 is led out through the cable routing assembly 3. The cable routing assembly 3 is used for the cable arrangement in the cable storage slot 21. In this way, the cable can be led to the drum 2 or led out of the drum 2 through the cable routing assembly 3, ensuring that the cable is laid out and taken back in a more orderly manner, avoiding excessive bending or knotting of the cable, and preventing the cable from collapsing laterally.

[0027] The drive assembly includes a power component 4 and a clutch component 5. The power component 4 is connected to the bracket 1, and the output end of the power component 4 is connected to the rotating shaft via the clutch component 5. The clutch component 5 is used to control the engagement or disengagement of the power transmission between the power component 4 and the rotating shaft. The power component 4 can be connected to the rotating shaft via the clutch component 5, thereby driving the drum 2 to rotate, or the clutch component 5 can disengage the power transmission between the power component 4 and the rotating shaft, so that the rotation of the power component 4 and the rotation of the drum 2 do not affect each other.

[0028] The cable winding device 100 of this embodiment can drive the drum 2 to rotate via a drive component. This allows for automatic cable winding by rotating the drum 2 during take-up, reducing labor intensity and improving work efficiency. During unwinding, the clutch engages, disconnecting the power transmission between the power component 4 and the drum 2. The cable can then be automatically unwound from the drum 2 as the equipment in front moves, unaffected by the power component 4, resulting in good overall practicality. This embodiment can also utilize the cable arrangement component 3 to arrange the cable neatly within the cable storage slot 21.

[0029] See Figure 4 In some embodiments, the clutch component 5 includes a housing 51, a first transmission component 52, and a control component. The housing 51 is connected to the drum 2 and rotates synchronously with the drum 2. The housing 51 can be fixed to one end of the drum 2 by bolts.

[0030] The first transmission component 52 is connected to the output end of the power component 4. The first transmission component 52 and the housing 51 have a first state and a second state. In the first state, the housing 51 and the first transmission component 52 are engaged and rotate synchronously. When the power component 4 is activated, it can drive the drum 2 to move synchronously. In the second state, the first transmission component 52 and the housing 51 can rotate relative to each other. At this time, the rotation of the drum 2 is not affected by the power component 4, and the drum 2 can rotate on its own, improving practicality during cable unwinding. This embodiment can achieve stable operation of the drum 2 through the engagement and disengagement of the clutch component 5 during cable winding and unwinding, making cable winding and unwinding more convenient.

[0031] A control unit is connected between the housing 51 and the first transmission member 52, and is used to control the switching between the first transmission member 52 and the housing 51 in a first state and a second state. The control unit can actively control the engagement or disengagement of the housing 51 and the first transmission member 52 according to the operating conditions.

[0032] In some embodiments, the control component includes a first driver 53 and a coupling member 54. A first transmission member 52 is rotatably connected to a housing 51. The first transmission member 52 is provided with a first coupling portion, and the housing 51 is provided with a second coupling portion. The first driver 53 is connected to the coupling member 54 and controls the coupling member 54 to move axially on the rotating shaft.

[0033] Both the first and second joints are joint grooves. In the first state, the joint member 54 is disposed in the joint groove, and in the second state, the joint member 54 is separated from the joint groove.

[0034] Preferably, the coupling member 54 has a key portion 541, and both the first coupling portion and the second coupling portion are keyways.

[0035] When the power unit 4 needs to drive the drum 2 to rotate for winding, the first driver 53 drives the coupling member 54 to move along the axial direction of the rotating shaft and insert it into the coupling groove, thereby realizing the transmission of torque by using the coupling member 54.

[0036] For example, the connector 54 has a first key portion 541 and a second key portion 541. The first key portion is always at least partially inserted into the first key portion 541 of the connector 54, and the second key portion is inserted into the second key portion 541 of the connector 54 in the first state and separated from each other in the second state.

[0037] Furthermore, the housing 51 has an inner cavity extending axially along the rotating shaft, part of which is configured as a sliding cavity 511. The first actuator 53 includes a piston 55 and a piston rod 56 connected to each other. The piston 55 is slidably disposed within the sliding cavity 511. The end of the housing 51 away from the piston rod 56 is configured as a medium inlet 57. The piston 55 can be driven pneumatically or hydraulically. The end of the piston rod 56 is connected to the coupling member 54. A reset member 58 is provided between the side of the piston 55 away from the medium inlet 57 and the housing 51. The reset member 58 can be a spring.

[0038] When the drum 2 needs to wind up the cable, there is no high-pressure gas in the medium inlet 57 and it is connected to the outside atmosphere. The reset member 58 can push the piston 55 to the left and reset the piston 55 to the initial state. At this time, the coupling member 54 can be inserted into the keyway of the first coupling part and the second coupling part, thereby realizing the engagement of the power transmission between the housing 51 and the first transmission member 52. When the power component 4 rotates, it can drive the drum 2 to rotate synchronously to realize the winding of the cable.

[0039] When the equipment located in front of the drum 2 in the tunnel moves forward, high-pressure gas or liquid is introduced into the medium inlet 57, which pushes the piston 55 to move to the right to compress the reset member 58. At this time, the coupling member 54 separates from the keyway of the first coupling part and / or the second coupling part, thereby realizing the separation of the power transmission between the housing 51 and the first transmission member 52. The drum 2 is in a relaxed state. When the equipment in front moves and drives the cable to move, the drum 2 will rotate on its own to release the cable, and it is not affected by the power component 4.

[0040] In some embodiments, the clutch component 5 is located at the first end of the rotating shaft, and the second end of the rotating shaft is provided with an interface component 6. The interface component 6 has a cable interface 61 and a media interface. A slip ring is provided between the interface component 6, the drum 2, and the support 1. The rotating shaft has a first end and a second end along its axial direction. The first end can be the right end of the rotating shaft, and the second end can be the left end of the rotating shaft. The slip ring is a rotary pneumatic-electric composite slip ring, which ensures that the electric, pneumatic, or hydraulic transmission is not affected during the rotation of the drum 2.

[0041] When the cable is an electric cable, one end of the cable is connected to the cable interface 61, and the other end of the cable is connected to the equipment in front. When the cable is a gas pipe or a liquid pipe, one end of the cable is connected to the medium interface, and the other end of the cable can be connected to the equipment in front or to the medium inlet 57 of the clutch component 5. In this case, the connection between the medium interface, the medium inlet 57 and the cable can be achieved by arranging a three-way valve.

[0042] In some embodiments, the power component 4 includes a second driver 41 and a second transmission component 42. The second transmission component 42 is located at the output end of the second driver 41. The first transmission component 52 and the second transmission component 42 are sprockets or pulleys. A synchronous chain 43 or a synchronous belt is provided between the second transmission component 42 and the first transmission component 52.

[0043] The first driver 53 and the second driver 41 can be pneumatically driven or hydraulically driven. For example, a pneumatic motor or a hydraulic motor.

[0044] For example, both the first transmission component 52 and the second transmission component 42 are sprockets, and a synchronous chain 43 is provided between the first transmission component 52 and the second transmission component 42.

[0045] See Figure 3 and Figure 4In some embodiments, the clutch component 5 further includes a third transmission component 59, which is connected to the housing 51 and rotates synchronously with the housing 51. The third transmission component 59 is also connected to the cable laying assembly 3. The cable laying assembly 3 includes a cable laying frame 31, a reciprocating screw 32, a guide rod 33, a lead screw nut 34, a guide wheel 35, and a fourth transmission component 36. The reciprocating screw 32 is rotatably connected to the cable laying frame 31, and the axial direction of the reciprocating screw 32 is parallel to the axial direction of the rotating shaft. When the drum 2 rotates, both the housing 51 and the third transmission component 59 rotate synchronously with the drum 2, thereby enabling the cable laying assembly 3 to move synchronously with the drum 2, resulting in more stable and efficient cable laying and better timeliness.

[0046] The guide rod 33 is connected to the cable tray 31 and is parallel to the reciprocating screw 32. The lead screw nut 34 has a lead hole and a guide hole. The reciprocating screw 32 passes through the lead hole, and the guide rod 33 passes through the guide hole. The guide wheel 35 is connected to the lead screw nut 34 and moves synchronously with the lead screw nut 34 along the axial direction of the reciprocating screw 32. The fourth transmission component 36 is connected to the reciprocating screw 32, and the fourth transmission component 36 and the third transmission component 59 are connected in a transmission connection. The cable passes through the guide wheel 35 and can be driven by the guide wheel 35 to move the cable axially along the reciprocating screw 32 for cable laying.

[0047] When the reciprocating screw 32 rotates, the nut 34 can move back and forth along the axial direction of the reciprocating screw 32 and the guide rod 33, thereby making the cable in the cable storage groove 21 more evenly and uniformly arranged in the circumferential direction.

[0048] In this embodiment, the reciprocating lead screw 32 can realize the reciprocating movement of the lead nut 34 in the axial direction of the reciprocating lead screw 32 without changing the rotation direction of the lead screw, thereby greatly improving its practicality.

[0049] Both the fourth transmission component 36 and the third transmission component 59 are sprockets or pulleys, and a synchronous chain 43 or synchronous belt is provided between the fourth transmission component 36 and the third transmission component 59. For example, both the third transmission component 59 and the fourth transmission component 36 are sprockets, and a synchronous chain 43 is provided between the third transmission component 59 and the fourth transmission component 36.

[0050] The transmission ratio of the fourth transmission component 36 and the third transmission component 59 meets the first threshold, which makes the speed at which the nut 34 moves axially along the reciprocating screw 32 highly matched with the rotation speed of the drum 2, resulting in a more orderly cable arrangement.

[0051] In some embodiments, the support 1 includes a first frame 11, a second frame 12, and connecting rods 13. The first frame 11 and the second frame 12 are arranged at intervals along the axial direction of the rotating shaft. Multiple connecting rods 13 connect the first frame 11 and the second frame 12. Each of the first frame 11 and the second frame 12 includes a base 111, multiple rod portions 112 arranged circumferentially at intervals along the base 111, and reinforcing rod portions 113 connecting adjacent rod portions. The base 111 is used to connect to the rotating shaft. There can be four rod portions 112, which are equally spaced circumferentially along the base 111. The reinforcing rod portions 113 connect adjacent rod portions 112, improving the overall structural stability. The support 1 of this embodiment has a simple overall structure, is lightweight, easy to assemble and transport underground, and has good practicality.
