Description

Technical Field

[0001] This invention belongs to the field of power supply technology for engineering machinery, specifically referring to an adjustable cable winding and conveying machine. Background Technology

[0002] Electrification retrofits for construction machinery can significantly reduce equipment energy consumption and exhaust emissions. However, power supply configuration for these retrofitted machines presents a major challenge. Existing technologies often rely on large battery packs carried by the machinery for power, which significantly increases retrofit costs and equipment weight. For construction machinery operating within limited ranges (such as mining loaders, excavators, and factory handling vehicles), external cables can significantly reduce weight and provide more stable power. However, since these machines are constantly in motion, the cables need to be continuously wound, unwound, and transported. Existing cable winding and conveying systems are ill-suited for dynamic winding and unwound transport based on cable movement, making them unsuitable for direct application in electrified construction machinery.

[0003] Current power supply methods for construction machinery via cables have many problems, such as:

[0004] Construction machinery constantly undergoes irregular movements, which carry cables along with it. These cables are prone to slackness, dragging on the ground, excessive tension, or even breakage. When the machinery is near a power source, the cable may slack. Current technology typically requires a complex control system to individually control the winch to wind up the cable, which introduces lag and can easily lead to the cable dragging on the ground or becoming tangled. When the machinery is away from a power source, the cable may suddenly become taut. If the winch does not release and deliver the cable in time, the cable tension can easily become too great and eventually break.

[0005] Existing cable winding and conveying systems are unable to respond promptly to the movement of construction machinery and automatically control the winding and unwinding of cables, making it difficult to continuously apply reasonable tension to the cables. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides an adjustable cable winding and conveying machine. It employs a driver to dynamically drive the winch, and a pressure feedback device senses the cable tension and feeds it back to the driver, thereby automatically adjusting the winch's driving conditions. This enables automatic cable winding, automatic cable release, and continuous tautness, effectively solving the problems of existing technologies that struggle to control cable winding and release in real time based on the movement of construction machinery, and that maintaining stable tension during cable winding and release.

[0007] The technical solution adopted by this invention is as follows: This solution provides an adjustable cable winding conveyor, including a conveying support, a hinge, a winch, a driver, a limiter, and a pressure feedback device. The hinge is rotatably mounted on the upper wall of the conveying support, the winch is rotatably mounted on the inner wall of the hinge, and the driver is fixedly mounted on the outer wall of the hinge. The driver and the winch are connected in a transmission configuration. When winding the cable, the driver drives the winch to rotate and wind up the cable. When releasing the conveyed cable, the driver applies rotational resistance to the winch. The limiter is fixedly mounted on the hinge using a crossbar and is located on one side of the winch. It is used to laterally limit the cable movement. The pressure feedback device is vertically slidably engaged with the limiter. The pressure feedback device is used to monitor the cable movement. The cable is guided and its tension is automatically monitored. The pressure feedback device is electrically connected to the driver. A brush box is fixedly installed on the hinge. The winch shaft rotates through the brush box. A conductive disk is coaxially fixedly installed on the winch shaft. The conductive disk is located inside the brush box. An elastic brush is fixedly installed on the inner wall of the brush box. The elastic brush is in frictional pressure against the side wall of the conductive disk. A cable is wound on the winch. The inner end of the cable is fixedly connected to the inner wall of the winch and electrically connected to the conductive disk. The outer end of the cable passes through the limit switch and the pressure feedback device and is connected to the external power output. A transformer controller is fixedly installed on the outer wall of the hinge. The elastic brush is electrically connected to the power supply of the construction machinery through the transformer controller.

[0008] Furthermore, the driver includes a drive motor and a drive housing. The drive motor is fixedly mounted on the outer wall of the hinge seat, and the drive housing is fixedly mounted on the upper outer wall of the drive motor housing. The output shaft of the drive motor rotates through and extends into the drive housing. A locking disc is coaxially fixedly mounted on the end of the output shaft of the drive motor. A sliding rod is slidably arranged in a ring array on the locking disc. A reducer is fixedly mounted on the inner wall of the drive housing. A driven disc is coaxially fixedly connected to the input end of the reducer. The driven disc and the locking disc are coaxially corresponding. A driven ring is fixedly mounted on the lower wall of the driven disc. The sliding rod is configured to cooperate with the driven ring. The sliding rod provides frictional drive or applies resistance to the driven ring. A bevel gear one is coaxially fixedly connected to the output end of the reducer. A bevel gear two is coaxially fixedly mounted on the shaft of the winch. The bevel gear two is located inside the drive housing and is meshed with the bevel gear one for transmission.

[0009] The sliding direction of the slide rod points towards the axis of the locking disc. A friction block is fixedly provided in the middle of the slide rod, and the friction block is corresponding to the inner circumferential wall of the driven ring. A resistance wheel is provided at the outer end of the slide rod, and the resistance wheel is corresponding to the outer circumferential wall of the driven ring. The driven ring passes through the gap between the friction block and the resistance wheel. A tension spring is connected between the end of the slide rod and the upper wall of the locking disc.

[0010] The limiter includes a longitudinal guide rail and limit rollers. The longitudinal guide rail is fixedly connected to the hinge seat by a crossbar. The longitudinal guide rail is vertically set on one side of the winch. The limit rollers are symmetrically distributed and rotatably set on the outer side wall of the longitudinal guide rail. The cable passes between the two limit rollers.

[0011] In a preferred embodiment of the present invention, the pressure feedback device includes a slide, an outer roller, an inner roller, a slider, an elastic telescopic rod, and a pressure roller. The slide is vertically slidably engaged with a longitudinal guide rail. The outer roller and the inner roller are rotatably mounted on the upper wall of the slide. The slider is vertically slidably engaged with the side wall of the slide. A lead screw is vertically mounted on the slide and rotatably connected to the slide. The lead screw thread passes through the slider, and a turning wheel is fixedly connected to the upper end of the lead screw. The elastic telescopic rod is fixedly mounted on the bottom wall of the slider. The elastic telescopic rod is vertically positioned and faces between the outer roller and the inner roller, allowing for elastic extension and contraction. A spring is installed inside the base of the rod. The two ends of the spring are fixedly connected to the base and the telescopic part of the elastic telescopic rod, respectively. A push switch is fixedly installed on the inner top wall of the base of the elastic telescopic rod. The push switch is electrically connected to the drive motor. When the push switch is pressed, the drive motor stops running. When the push switch is released, the drive motor runs. The pressure roller is located at the telescopic end of the elastic telescopic rod. The pressure roller is located between the outer roller and the inner roller. After the cable is led out from the external power source, it passes through the upper part of the outer roller, the lower part of the pressure roller, and the upper part of the inner roller in sequence before being wound into the winch.

[0012] As another preferred embodiment of the present invention, the pressure feedback device differs from the aforementioned embodiment in that the slider is fixedly mounted on the side wall of the carriage, and the lead screw is no longer mounted on the carriage.

[0013] The beneficial effects achieved by this invention are as follows:

[0014] (1) The present invention uses a driver to dynamically drive the winch, and combines a pressure feedback device to sense the tension of the cable and feed it back to the driver, thereby realizing automatic adjustment of the winch transmission condition. When the cable is loose, the pressure feedback device senses that the tension of the cable is reduced and controls the driver to lock the winch and automatically wind up the cable. When the cable is taut and being pulled, the driver no longer locks the winch, but provides rotational resistance to the winch, which facilitates the cable to be pulled out and released and transported outward. The cable is kept taut during the process of being pulled out, which effectively solves the problem that the prior art is difficult to control the cable winding and release and transport in real time according to the motion state of the engineering machinery, and effectively solves the problem that the prior art is difficult to maintain a stable tension during the winding and release and transport of the cable.

[0015] (2) The pressure feedback device uses the outer roller and inner roller to form the cable fulcrum and the pressure roller to form the pressure sensing point. It uses the displacement change generated when the cable is tightened and loosened to feed back to the extension and retraction of the elastic telescopic rod, thereby realizing the control of the drive motor and achieving a higher degree of automation.

[0016] (3) The sliding rod on the locking disc uses the centrifugal force of rotation to drive the driven disc. When the drive motor drives the locking disc to rotate quickly, the sliding rod gradually moves away from the axis of the locking disc under the centrifugal force of rotation, so that the friction block presses against the inner circumferential wall of the driven ring, thereby locking the driven disc, which can drive the winch to wind up the cable. When the drive motor is de-energized, the sliding rod approaches the shaft of the locking disc under the action of the tension spring, the friction block leaves the inner circumferential wall of the driven ring, and the resistance wheel presses against the outer circumferential wall of the driven ring, providing rotational resistance for the winch, so that the cable remains taut during the stretching and release process.

[0017] (4) Since the hinge is rotated on the upper wall of the conveying support and the cable is in a taut state, when the construction machinery moves off-center, the cable can make the hinge rotate as a whole through the limit roller and make the winch continuously aligned with the external power source, thereby ensuring that the cable is not subjected to oblique shearing force.

[0018] (5) The flexible brush is in continuous contact with the conductive disk and is energized, thereby ensuring that the cable can continuously supply power to the engineering machinery. Attached Figure Description

[0030] Example 1: Please refer to Figures 1-9 This embodiment provides an adjustable cable winding conveyor, including a conveying support 1, a hinge 2, a winch 3, a driver 4, a limiter 5, and a pressure feedback device 6. The hinge 2 is rotatably mounted on the upper wall of the conveying support 1, the winch 3 is rotatably mounted on the inner wall of the hinge 2, and the driver 4 is fixedly mounted on the outer wall of the hinge 2. The driver 4 and the winch 3 are connected in a transmission configuration. When winding the cable 32, the driver 4 drives the winch 3 to rotate and wind the cable 32. When releasing and conveying the cable 32 outward, the driver 4 can apply rotational resistance to the winch 3. The limiter 5 is fixedly mounted on the hinge 2 using a crossbar 21. The limiter 5 is located on one side of the winch 3 and is used to laterally limit the cable 32. The pressure feedback device 6 is vertically slidably engaged with the limiter 5. The pressure feedback device 6 is used to guide the cable 32 and automatically monitor the cable 32. 2. Tension force: The pressure feedback device 6 is electrically connected to the driver 4. A brush box 22 is fixedly installed on the hinge 2. The shaft of the winch 3 rotates through the brush box 22. A conductive disk 31 is coaxially fixedly installed on the shaft of the winch 3. The conductive disk 31 is located inside the brush box 22 and is made of pure copper. An elastic brush 221 is fixedly installed on the inner wall of the brush box 22. The elastic brush 221 is frictionally pressed against the side wall of the conductive disk 31. A cable 32 is wound on the winch 3. The inner end of the cable 32 is fixedly connected to the inner wall of the winch 3 and electrically connected to the conductive disk 31. The outer end of the cable 32 passes through the limiter 5 and the pressure feedback device 6 and is connected to the external power output terminal. A transformer controller 23 is fixedly installed on the outer wall of the hinge 2. The elastic brush 221 is electrically connected to the power supply terminal of the engineering machinery through the wire and the transformer controller 23.

[0031] The driver 4 includes a drive motor 41 and a drive housing 42. The drive motor 41 is fixedly mounted on the outer wall of the hinge 2, and the drive housing 42 is fixedly mounted on the upper outer wall of the drive motor 41. The output shaft of the drive motor 41 extends through and into the drive housing 42. A locking disc 411 is coaxially fixedly mounted on the end of the output shaft of the drive motor 41. A sliding rod 412 is arranged in a circular array on the locking disc 411. The sliding direction of the sliding rod 412 points towards the axis of the locking disc 411. A friction block 413 is fixedly mounted in the middle of the sliding rod 412. A resistance wheel 414 is provided at the outer end of the sliding rod 412. A tension spring 415 is connected between the end of the sliding rod 412 and the upper wall of the locking disc 411. A reducer 421 is fixedly mounted on the inner wall of the drive housing 42. A driven disc 422 is coaxially fixedly connected to the input end of the reducer 421. The driven disc 422 and the locking disc 411 are coaxially corresponding. A driven ring 423 is fixedly installed on the lower wall of the driven disc 422. The friction block 413 is correspondingly set to the inner circumferential wall of the driven ring 423. The resistance wheel 414 is correspondingly set to the outer circumferential wall of the driven ring 423. The driven ring 423 passes through the gap between the friction block 413 and the resistance wheel 414. After the friction block 413 on the slide rod 412 comes into pressure contact with the driven ring 423, it drives the ring 423 by friction. After the resistance wheel 414 on the slide rod 412 comes into pressure contact with the driven ring 423, it applies resistance to the ring 423. A bevel gear 424 is coaxially fixedly connected to the output end of the reducer 421. A bevel gear 33 is coaxially fixedly installed on the shaft of the winch 3. The bevel gear 33 is located inside the drive box 42. The bevel gear 33 meshes with the bevel gear 424.

[0032] The limiter 5 includes a longitudinal guide rail 51 and a limit roller 52. The longitudinal guide rail 51 is fixedly connected to the hinge seat 2 by a crossbar 21. The longitudinal guide rail 51 is vertically arranged on one side of the winch 3. The limit rollers 52 are symmetrically distributed and rotatably arranged on the outer side wall of the longitudinal guide rail 51. The cable 32 passes between the two limit rollers 52.

[0033] The pressure feedback device 6 includes a slide 61, an outer roller 62, an inner roller 63, a slider 64, an elastic telescopic rod 65, and a pressure roller 66. The slide 61 is vertically slidably connected to the longitudinal guide rail 51. The outer roller 62 and the inner roller 63 are rotatably mounted on the upper wall of the slide 61. The slider 64 is fixedly mounted on the side wall of the slide 61. The elastic telescopic rod 65 is fixedly mounted on the bottom wall of the slider 64. The elastic telescopic rod 65 is vertically arranged and faces between the outer roller 62 and the inner roller 63. A spring 651 is provided inside the base of the elastic telescopic rod 65. The two ends of the spring 651 are respectively connected to the base of the elastic telescopic rod 65 and the telescopic rod. The base of the elastic telescopic rod 65 is fixedly connected to a push switch 652, which is electrically connected to the drive motor 41. When the push switch 652 is pressed, the drive motor 41 stops running. When the push switch 652 is released, the drive motor 41 runs. The pressure roller 66 is rotatably located at the telescopic end of the elastic telescopic rod 65. The pressure roller 66 is located between the outer roller 62 and the inner roller 63. After the cable 32 is led out from the external power source, it passes around the upper part of the outer roller 62, passes between the two limit rollers 52, passes around the lower part of the pressure roller 66, and the upper part of the inner roller 63 before being wound into the winch 3.

[0034] The specific usage process of this embodiment is as follows:

[0035] The adjustable cable reel in this embodiment is fixedly installed on the engineering machinery after electrification. The transformer controller 23 is electrically connected to the power supply end of the engineering machinery. The outer end of the cable 32 is connected to the external power output end. After the cable 32 is led out from the external power supply, it passes around the upper part of the outer roller 62, passes between the two limiting rollers 52, passes around the lower part of the pressure roller 66, and the upper part of the inner roller 63 before being wound into the winch 3.

[0036] When the construction machinery is in operation, it moves along with the adjustable cable reel. When the construction machinery is close to an external power source, the cable 32 will loosen, and the cable 32 between the outer roller 62 and the inner roller 63 will also be loose. Then, the elastic telescopic rod 65 will extend under the pushing action of the spring 651, so that the pressure roller 66 presses the cable 32. The telescopic part of the elastic telescopic rod 65 will move away from the push switch 652, and the drive motor 41 will start, driving the locking disc 411 to rotate rapidly. Under the centrifugal force of rotation, the slide rod 412 will gradually move away from the axis of the locking disc 411 until the friction block 413 presses against the inner circumferential wall of the driven ring 423. At this time, the locking disc 411 drives the driven ring 423 and the driven disc 422 to rotate through the friction action between the friction block 413 and the driven ring 423. The reducer 421 drives the bevel gear 1 424 to rotate, so that the bevel gear 2 33 drives the winch 3 to rotate slowly, thereby winding up the cable 32.

[0037] As winding proceeds, the cable 32 is gradually tightened, and the cable 32 between the outer roller 62 and the inner roller 63 is also tightened, causing the pressure roller 66 to move upward and compress the elastic telescopic rod 65. When the telescopic part of the elastic telescopic rod 65 presses against the push switch 652, the tension of the cable 32 reaches the target. At this time, the drive motor 41 stops running, the locking disc 411 stops rotating, and the slide rod 412 approaches the rotating shaft of the locking disc 411 under the action of the tension spring 415. The friction block 413 moves away from the inner circumferential wall of the driven ring 423, and the resistance wheel 414 presses against the outer circumferential wall of the driven ring 423. The resistance wheel 414 provides rotational resistance to the driven ring 423, thereby providing rotational resistance to the winch 3, so that the cable 32 remains taut.

[0038] When the construction machinery is away from the external power source, it will pull the cable 32, which will remain taut. The telescopic part of the elastic telescopic rod 65 will continuously press the push switch 652, and the drive motor 41 will not run. The resistance wheel 414 will continue to press against the outer circumferential wall of the driven ring 423, providing rotational resistance for the winch 3. When the construction machinery pulls the cable 32, the winch 3 will rotate to release and transport the cable 32 outward. During this process, the winch 3 will still be able to apply tension to the cable 32 due to the rotational resistance, preventing the cable 32 from suddenly loosening.

[0039] During the operation of the engineering machinery, the direction of the conveying support 1 relative to the external power source will also change. Since the hinge 2 is rotatably mounted on the upper wall of the conveying support 1, the cable 32 is in a taut state. The cable 32 can make the hinge 2 rotate as a whole through the limiting roller 52, and make the winch 3 continuously aligned with the external power source, thereby ensuring that the cable 32 is not subjected to oblique shearing force.

[0040] When the winch 3 rotates, the conductive disk 31 rotates, and the elastic brush 221 continuously contacts and is energized with the conductive disk 31, thereby ensuring that the cable 32 can continuously supply power to the engineering machinery.

[0041] Example 2: This example is based on Example 1, the difference being that the pressure feedback device 6 in this example is different from that in Example 1. Please refer to [link / reference]. Figures 1-6 , Figures 8-10In this embodiment, the pressure feedback device 6 includes a slide 61, an outer roller 62, an inner roller 63, a slider 64, an elastic telescopic rod 65, and a pressure roller 66. The slide 61 is vertically slidably engaged with the longitudinal guide rail 51. The outer roller 62 and the inner roller 63 are rotatably mounted on the upper wall of the slide 61. The slider 64 is vertically slidably engaged with the side wall of the slide 61. A lead screw 611 is vertically mounted on the slide 61 and rotatably connected to the slide 61. The lead screw 611 is threaded through the slider 64. A screw wheel 612 is fixedly connected to the upper end of the lead screw 611. The elastic telescopic rod 65 is fixedly mounted on the bottom wall of the slider 64. The elastic telescopic rod 65 is vertically positioned and faces between the outer roller 62 and the inner roller 63. A spring 651 is provided inside the base part. The two ends of the spring 651 are fixedly connected to the base part and the telescopic part of the elastic telescopic rod 65, respectively. A push switch 652 is fixedly provided on the inner top wall of the base part of the elastic telescopic rod 65. The push switch 652 is electrically connected to the drive motor 41. When the push switch 652 is pressed, the drive motor 41 stops running. When the push switch 652 is released, the drive motor 41 runs. The pressure roller 66 is rotatably located at the telescopic end of the elastic telescopic rod 65. The pressure roller 66 is located between the outer roller 62 and the inner roller 63. After the cable 32 is led out from the external power source, it passes around the upper part of the outer roller 62, passes between the two limiting rollers 52, passes around the lower part of the pressure roller 66, and the upper part of the inner roller 63 before being wound into the winch 3.

[0042] In practical use, this embodiment is basically the same as that of embodiment one, except that before use, the operator can rotate the screw 611 by turning the screw wheel 612 to make the slider 64 slide vertically along the side wall of the slide frame 61, thereby adjusting the height of the slider 64 and the initial position of the elastic telescopic rod 65 and the pressure roller 66. When the construction machinery is close to the external power source, the winch 3 winds up the cable 32. Since the initial position of the pressure roller 66 is different from that in embodiment one, the tension of the cable 32 is also different when the base of the elastic telescopic rod 65 presses against the push switch 652, thereby realizing the adjustment of the tension of the cable 32.

[0043] The present invention and its embodiments have been described above. This description is not restrictive, and the figures shown are only one embodiment of the present invention. The actual structure is not limited to this.
