Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of power supply of engineering machinery, and particularly relates to an adjustable cable winding conveyor. BACKGROUND

[0002] Electrification of engineering machinery can significantly reduce equipment energy consumption and exhaust emission, and power supply configuration of the engineering machinery after electrification becomes a big problem. In the prior art, part of the technology directly supplies power by carrying large battery packs on the engineering machinery, which significantly increases the equipment modification cost and greatly increases the equipment self-weight. For the engineering machinery used in a limited activity range (such as mine site shovels, excavators, and plant indoor carriers), using external cables to supply power can significantly reduce the equipment self-weight and make the power supply more stable. However, since the engineering machinery needs to be constantly moved, the cable needs to be constantly wound, released and conveyed. The existing cable winding conveyor is difficult to dynamically wind and release and convey according to the movement state of the cable, and is difficult to be directly applied to the electrified engineering machinery.

[0003] The current engineering machinery cable power supply method has many problems, for example: The engineering machinery will constantly move irregularly, which will move with the cable, and the cable is prone to the risk of being slack and dragging the ground or being excessively tight and even being pulled off. When the engineering machinery is close to the power supply, the cable will be slack. The existing technology usually needs a complex control system to separately control the winch to wind the cable, which has a lagging nature and is prone to cause the cable to drag the ground or be wound and curled. When the engineering machinery is away from the power supply, the cable will be suddenly stretched and tightened. If the winch does not timely release and convey the cable, the cable is prone to have excessive tension and be broken.

[0004] The existing cable winding conveyor is difficult to timely respond to the movement of the engineering machinery and automatically control the winding and release and conveying of the cable, and is difficult to continuously apply a reasonable tension to the cable. SUMMARY

[0018] The pressure feedback device 6 comprises a sliding frame 61, an outer roller 62, an inner roller 63, a sliding block 64, an elastic telescopic rod 65 and a pressure roller 66. The sliding frame 61 is vertically and slidingly connected to the longitudinal guide rail 51. The outer roller 62 and the inner roller 63 are respectively rotatably arranged on the upper wall of the sliding frame 61. The sliding block 64 is fixedly arranged on the side wall of the sliding frame 61. The elastic telescopic rod 65 is fixedly arranged on the bottom wall of the sliding block 64. The elastic telescopic rod 65 is vertically arranged and faces the space between the outer roller 62 and the inner roller 63. A spring 651 is arranged in the base portion of the elastic telescopic rod 65. The two ends of the spring 651 are respectively fixedly connected to the base portion and the telescopic portion of the elastic telescopic rod 65. A press switch 652 is fixedly arranged on the inner top wall of the base portion of the elastic telescopic rod 65. The press switch 652 is electrically connected to the driving motor 41. When the press switch 652 is pressed, the driving motor 41 stops running. When the press switch 652 is released, the driving motor 41 runs. The pressure roller 66 is rotatably arranged on 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 supply, it is wound around the upper portion of the outer roller 62, passes between the two limiting rollers 52, is wound around the lower portion of the pressure roller 66 and the upper portion of the inner roller 63, and is then wound into the winch 3.

[0019] The specific use process of the embodiment is as follows: The adjustable cable winder in the embodiment is fixedly installed on the engineering machinery after electrification reconstruction. The variable voltage 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 output end of the external power supply. After the cable 32 is led out from the external power supply, it is wound around the upper portion of the outer roller 62, passes between the two limiting rollers 52, is wound around the lower portion of the pressure roller 66 and the upper portion of the inner roller 63, and is then wound into the winch 3.

[0020] When the engineering machinery works, the adjustable cable winder moves as a whole. When the engineering machinery approaches the external power supply, the cable 32 is loose, and the cable 32 between the outer roller 62 and the inner roller 63 is also in a loose state. The elastic telescopic rod 65 is elongated under the pushing action of the spring 651, so that the pressure roller 66 tightly presses the cable 32. The telescopic portion of the elastic telescopic rod 65 is away from the press switch 652, so that the driving motor 41 is started to drive the locking disc 411 to rotate rapidly. The sliding rod 412 gradually moves away from the shaft center of the locking disc 411 under the rotating centrifugal force, until the friction block 413 is pressed 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 between the friction block 413 and the driven ring 423. The bevel gear one 424 is driven to rotate through the speed reducer 421, so that the bevel gear two 33 drives the winch 3 to rotate slowly, thereby winding the cable 32.

[0021] As the winding proceeds, the cable 32 is gradually taut, the cable 32 between the outer roller 62 and the inner roller 63 is also taut, so that the compression roller 66 moves upward, compressing the elastic telescopic rod 65, when the telescopic part of the elastic telescopic rod 65 presses the push switch 652, the tension of the cable 32 reaches the standard, at this time, the driving motor 41 stops running, the locking disc 411 stops rotating, 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 leaves the inner circumferential wall of the driven ring 423, and the resistance wheel 414 is pressed against the outer circumferential wall of the driven ring 423, so that the driven ring 423 is provided with rotational resistance, thereby providing the capstan 3 with rotational resistance, so that the cable 32 remains taut.

[0022] When the construction machinery is far away from the external power source, the cable 32 is pulled, the cable 32 remains in a taut state, the telescopic part of the elastic telescopic rod 65 continuously presses the push switch 652, the driving motor 41 does not run, and the resistance wheel 414 continuously presses against the outer circumferential wall of the driven ring 423 to provide the capstan 3 with rotational resistance. When the construction machinery pulls the cable 32, the capstan 3 rotates to release and deliver the cable 32 outward. In this process, the capstan 3 has rotational resistance, so that the cable 32 can still be continuously tensioned to prevent the cable 32 from suddenly loosening.

[0023] When the construction machinery is working, the direction of the delivery support 1 relative to the external power source also changes. Since the hinge base 2 is rotatably arranged on the upper wall of the delivery support 1, the cable 32 is in a taut state, so that the hinge base 2 can be rotated as a whole by the limiting roller 52, and the capstan 3 can be continuously aligned with the external power source, so that the cable 32 is not subjected to oblique shearing force.

[0024] When the capstan 3 rotates, the conductive disc 31 rotates, and the elastic brush 221 continuously contacts and is electrified with the conductive disc 31, so that the cable 32 can continuously supply power to the construction machinery.

[0025] Example Two: This example is based on Example One, the difference is that the pressure feedback device 6 of this example is different from that of Example One, please refer to Figures 1-6 、 Figures 8-10The pressure feedback device 6 in the embodiment comprises a sliding frame 61, an outer roller 62, an inner roller 63, a sliding block 64, an elastic telescopic rod 65 and a pressure roller 66. The sliding frame 61 is vertically and slidingly connected to the longitudinal guide rail 51. The outer roller 62 and the inner roller 63 are respectively rotatably arranged on the upper wall of the sliding frame 61. The sliding block 64 is vertically and slidingly connected to the side wall of the sliding frame 61. A screw rod 611 is vertically arranged on the sliding frame 61 and is rotatably connected to the sliding frame 61. The screw rod 611 is threaded through the sliding block 64. A twisting wheel 612 is fixedly connected to the upper end of the screw rod 611. The elastic telescopic rod 65 is fixedly arranged on the bottom wall of the sliding block 64 and is vertically arranged and faces the space between the outer roller 62 and the inner roller 63. A spring 651 is arranged in the base portion of the elastic telescopic rod 65. The two ends of the spring 651 are respectively fixedly connected to the base portion and the telescopic portion of the elastic telescopic rod 65. A pressing switch 652 is fixedly arranged on the inner top wall of the base portion of the elastic telescopic rod 65. The pressing switch 652 is electrically connected to the driving motor 41. When the pressing switch 652 is pressed, the driving motor 41 stops running. When the pressing switch 652 is released, the driving motor 41 runs. The pressure roller 66 is rotatably arranged on the telescopic end of the elastic telescopic rod 65 and is located between the outer roller 62 and the inner roller 63. After the cable 32 is drawn out from the external power source, it is wound around the upper portion of the outer roller 62, passes between the two limiting rollers 52 and is wound around the lower portion of the pressure roller 66 and the upper portion of the inner roller 63 and is then wound into the winch 3.

[0026] In the specific use, the embodiment is basically the same as the first embodiment. The difference is that before use, the operator can rotate the screw rod 611 through the twisting wheel 612 to make the sliding block 64 vertically slide along the side wall of the sliding frame 61, so as to adjust the height of the sliding block 64 and the initial positions of the elastic telescopic rod 65 and the pressure roller 66. When the engineering machinery approaches the external power source, the winch 3 winds the cable 32. Since the initial positions of the pressure roller 66 are different from those in the first embodiment, when the base portion of the elastic telescopic rod 65 presses the pressing switch 652, the tension of the cable 32 is also different, so as to adjust the tightening degree of the cable 32.

[0027] The above description of the application and its embodiments is not restrictive. The embodiments shown in the drawings are only one of the embodiments of the application, and the actual structure is not limited thereto.
