Description

Technical Field

[0001] The utility model relates to the field of cable corner pulleys, in particular to a cable electric corner pulley. Background Art

[0002] The cable corner pulley is an auxiliary tool for cable corner transportation. When the cable corner pulley is used, a certain angle is formed between multiple guide wheels to transport the cable in a corner. However, since the position of the guide wheels on the cable corner pulley is relatively fixed, the angle of the cable corner transportation is relatively fixed, which makes it inconvenient to perform flexible corner transportation operations at different angles.

[0003] Therefore, it is necessary to provide a new cable electric corner pulley to solve the above-mentioned technical problems. Utility Model Content

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0029] See also Figures 1 to 5 An embodiment of the present invention provides a cable electric corner pulley, which includes: a main shaft pulley 1, a guide pulley A2 and a guide pulley B3.

[0030] In the embodiments of the present invention, please refer to Figure 1 and Figure 4 The spindle wheel 1 is provided with a guide wheel A2 and a guide wheel B3 which are rotatably connected, and the spindle wheel 1, the guide wheel A2 and the guide wheel B3 have the same specifications. Specifically, a rotating shaft 11 is fixedly installed on the spindle wheel 1, and a counterweight plate 12 is fixedly installed at both ends of the rotating shaft 11, and a connecting plate A21 is fixedly installed on both sides of the guide wheel A2, and the sleeve end of the connecting plate A21 is fixedly engaged with a coaxially arranged outer gear ring A22, and the sleeve end of the connecting plate A21 and the outer gear ring A2 are fixedly engaged with each other. 2 are both rotatably mounted on the rotating shaft 11 on the main shaft wheel 1, and connecting plates B31 are fixedly mounted on both sides of the guide wheel B3, and the sleeve ends of the connecting plates B31 are fixedly engaged with the coaxially arranged outer gear ring B32, the sleeve ends of the connecting plates B31 and the outer gear ring B32 are both rotatably mounted on the rotating shaft 11 on the main shaft wheel 1, and the length of the connecting plate A21 is smaller than the length of the connecting plate B31, and the spacing between the connecting plates A21 on both sides of the guide wheel A2 is smaller than the spacing between the connecting plates B31 on both sides of the guide wheel B3;

[0031] Any one of the counterweight discs 12 is equipped with a drive assembly 4 for driving the guide wheel A2 and the guide wheel B3 to rotate. The drive assembly 4 includes a servo motor 41, which is fixedly mounted on the inner wall of the counterweight disc 12 through a frame, and two driving gears 42 with a smaller upper portion and a larger lower portion are fixedly mounted on the output end of the servo motor 41. The upper driving gear 42 is meshed with a central gear 43, and the central gear 43 is rotatably mounted on the counterweight disc 12. The central gear 43 is meshed with the outer ring gear A22, and the lower driving gear 42 is meshed with the outer ring gear B32.

[0032] It should be noted that: the servo motor 41 is turned on to drive the two upper and lower distributed driving gears 42 to rotate. Since the lower driving gear 42 is meshed with the outer ring gear B32, and the upper driving gear 42 is meshed with the outer ring gear A22 through the intermediate gear 43, the guide wheel A2 and the guide wheel B3 rotate towards each other around the rotating shaft 11 until the angles of the guide wheels A2 and B3 are adjusted, so that the cable corner pulley can perform flexible corner conveying operations at different corner angles (such as the attached Figure 1 shown);

[0033] When the cable turning pulley is not needed, the servo motor 41 is turned on to drive the guide wheel A2 and the guide wheel B3 to rotate toward each other around the rotation axis 11 until the guide wheel A2 and the guide wheel B3 rotate to the same plane, and then the servo motor 41 is turned off (see the attached figure). Figure 2 As shown), the area occupied by the cable corner pulley is reduced, making transportation easier;

[0034] In this embodiment, in order to ensure that the servo motor 41 can maintain a specific position and self-lock when it stops, self-locking logic can be added to the control algorithm. For example, when the servo motor 41 stops, the controller can continuously output a small torque to keep the servo motor 41 at the current position, thereby preventing position deviation caused by external forces or other factors. This is a prior art and will not be described in detail here.

[0035] Among them, the counterweight plate 12 above the main shaft wheel 1 is equipped with a rotating handle 13 to facilitate the rotation of the turning pulley.

[0036] In addition, in order to improve the stability of the guide wheels A2 and B3 in cable transportation, an auxiliary guide wheel A2' is installed between the two connecting plates A21, and an auxiliary guide wheel B3' is installed between the two connecting plates B31, so that the cable electric corner pulley has a five-wheel structure.

[0037] Furthermore, the main shaft wheel 1, guide wheel A, auxiliary guide wheel A2', guide wheel B and auxiliary guide wheel B3' realize multi-wheel linkage, and the connecting plate A21 and the connecting plate B31 are respectively equipped with drive motors for driving the auxiliary guide wheel A2' and the auxiliary guide wheel B3' to rotate. The drive motor drives the auxiliary guide wheel A2' and the auxiliary guide wheel B3' to rotate, thereby reducing the resistance during cable laying.

[0038] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
