Description

Technical Field

[0001] The invention relates to the technical field of equipment for releasing or unfolding filamentary materials, and in particular to a cable paying-out device which is convenient for loading and unloading materials. Background Art

[0002] Cable is wire and cable. In the process of implementing power engineering, it is often necessary to support the cable drum with cable wrapped around it through a pay-off device (or support frame). In actual use, it is necessary to move the cable drum with a diameter greater than 1 meter to the support frame by a forklift or crane, and then place a support shaft between the support frame and the cable drum to realize the discharge of the cable drum; there are also some pay-off frames that control the lateral rotation of the support structure of the bracket through a hydraulic rod to change the height of the bracket to facilitate the lifting and lowering of the pay-off drum.

[0003] After searching: the support structure disclosed in the patent with the authorization publication number CN109399330B and the name of "cable pay-off rack" requires the staff to drive the two screws to rotate through the transmission mechanism between the two screws to realize the rotation of the two support structures. However, this patent is the same as the existing cable pay-off rack. The opening direction of the support rod used to support the support shaft changes with the rotation of the support structure. When the wire drum and the rotating shaft are placed in the opening, it is also necessary to install a stop pin and other structures to prevent the wire drum from moving out of the opening during the movement of the support structure. However, after multiple uses, it was found that the stop pin was deformed, which made it inconvenient to remove the stop pin and required regular replacement of the stop pin. Summary of the invention

[0004] In order to solve the technical problems existing in the background technology, the present invention proposes a cable pay-off device which is convenient for loading and unloading.

[0005] The present invention provides a cable unwinding device for convenient loading and unloading, comprising a frame, a first support and a second support which are laterally rotatably mounted on the frame and are used to support a support shaft on a cable drum, and a driving member, wherein the driving member is used to drive the first support and the second support to rotate so as to change the height of the cable drum in the vertical direction;

[0006] Different from the prior art, a first mounting portion having a first opening is rotatably mounted on the first support, the first opening accommodates one end of the support shaft, a first fixing member is detachably mounted between the first mounting portion and the first support, and the first fixing member fixes the first mounting portion on the first support;

[0008] The first support and the second support both have a loading station and a wire-releasing station. When the first support and the second support are in the wire-releasing station, the wire drum installed on the first support and the second support is separated from the ground; when the first support and the second support are in the second station, the first mounting part and the second mounting part are rotated so that the openings of the first opening and the second opening are in a horizontal state, the outer diameter of the support shaft on the wire drum is smaller than the first opening and the second opening, the wire drum is rotated so that the support shaft is located in the first opening and the second opening, and then the first mounting part and the second mounting part are rotated so that the first opening and the second opening are in an upward position, and then the first mounting part and the second mounting part are fixed by the first fixing part and the second fixing part. When unloading, the first support and the second support are rotated to the loading station, and then the first opening and the second opening of the first mounting part and the second mounting part are rotated to a horizontal state, and then the wire drum is rotated to realize the separation of the wire drum from the first support and the second support. In this way, when the first support and the second support start to rotate and drive the wire drum to rise, the first opening and the second opening are basically facing upward, so as to prevent the support shaft from being separated from the first opening and the second opening, and to prevent the support shaft from being separated from the first opening and the second opening on the basis of facilitating loading and unloading.

[0009] As a further optimized solution of the present invention, the first opening is a U-shaped structure, and the width of the first opening is greater than the outer diameter of the support shaft. Preferably, when the first support is in the loading station, the axis of the arc surface at the bottom of the U-shaped first opening is on the same horizontal plane as the axis of the support shaft. In this way, when the wire drum is rotated so that the support shaft is in the first opening, the first mounting part support shaft will not interfere with each other, which facilitates the rotation of the first mounting part.

Preferably, when the second support is in the loading station, the axis of the arc surface at the bottom of the U-shaped second opening is on the same horizontal plane as the axis of the support shaft. In this way, when the wire drum is rotated so that the support shaft is in the second opening, the second mounting part support shaft will not interfere with each other, which facilitates the rotation of the second mounting part.

[0016] The second blocking member and the second opening form a second limiting hole with a larger aperture at the lower portion and a smaller aperture at the upper portion, and the other end of the support shaft passes through the second limiting hole.

[0017] As a further optimized solution of the present invention, the axis of rotation of the first mounting portion relative to the first support coincides with the axis of the arc-shaped surface of the bottom of the first opening, further reducing interference between the first mounting portion and the support shaft when rotating;

[0018] The axis of rotation of the second mounting portion relative to the second support coincides with the axis of the arc-shaped surface of the bottom of the second opening, further reducing interference with the support shaft when the second mounting portion is rotated.

[0039] Different from the prior art, a first mounting portion 7 having a first opening 70 is rotatably mounted on the first support 2, the first opening 70 accommodates one end of the support shaft 5, and a first fixing member 9 is detachably mounted between the first mounting portion 7 and the first support 2, the first fixing member 9 fixes the first mounting portion 7 on the first support 2;

[0041] The first support 2 and the second support 3 both have a loading station and a wire-releasing station. When the first support 2 and the second support 3 are in the wire-releasing station, the wire drum 4 installed on the first support 2 and the second support 3 is separated from the ground; when the first support 2 and the second support 3 are in the second station, the first mounting portion 7 and the second mounting portion 8 are rotated so that the openings of the first opening 70 and the second opening 80 are in a horizontal state, the outer diameter of the support shaft 5 on the wire drum 4 is smaller than the first opening 70 and the second opening 80, the wire drum 4 is rotated so that the support shaft 5 is located in the first opening 70 and the second opening 80, and then the first mounting portion 7 and the second mounting portion 8 are rotated so that the first opening 70 and the second opening 80 are in an upward position, and then the first mounting portion 7 and the second mounting portion 8 are fixed by the first fixing member 9 and the second fixing member 10. When unloading, the first support 2 and the second support 3 are rotated to the loading station, and then the first opening 70 and the second opening 80 of the first mounting portion 7 and the second mounting portion 8 are rotated to a horizontal state, and then the wire drum 4 is rotated to achieve the separation of the wire drum 4 from the first support 2 and the second support 3.

[0042] In some embodiments, the first opening 70 is preferably a U-shaped structure, and the width of the first opening 70 is greater than the outer diameter of the support shaft 5. Preferably, when the first support 2 is in the loading station, the axis of the arc surface at the bottom of the U-shaped first opening 70 is on the same horizontal plane as the axis of the support shaft 5.

[0043] In some embodiments, the second opening 80 is preferably a U-shaped structure, and the width of the second opening 80 is greater than the outer diameter of the support shaft 5. Preferably, when the second support 3 is in the loading station, the axis of the arc surface at the bottom of the U-shaped second opening 80 is on the same horizontal plane as the axis of the support shaft 5. In this way, when the wire drum 4 is rotated so that the support shaft 5 is in the second opening 80, the second mounting portion 8 is rotated without interference with the support shaft 5, which facilitates the rotation of the second mounting portion 8.

It should be noted that when the first support 2 is in the loading position, there is a certain gap between the support shaft 5 and the bottom of the first opening 70, and the support shaft 5 conflicts with the first limiting opening 1100;

[0048] The second blocking member 12 includes a second extension portion 120 and a second connecting portion 121, and the second connecting portion 121 and the second extension portion 120 are integrally formed.
