Description

Technical Field

[0001] The utility model relates to the technical field of wires, in particular to an axial row wire winding and unwinding machine. Background Art

[0002] At present, with the development of new energy, the requirements for power cables are getting higher and higher. Since the power to be transmitted by current power cables is increasing, the diameter and weight of the cables are increasing, and the weight of the wire reels with cables wound thereon is also greatly increased. Therefore, the requirements for wire winding and unwinding machines are also getting higher and higher. In the existing patent, the Chinese patent document with the application number 201310031748.3 discloses a self-propelled large-width heavy-duty wire winding and unwinding machine and its wire winding and unwinding method, which includes a ground rail, a first movable lifting wire winding device and a second movable lifting wire winding device. The first movable lifting wire winding device and the second movable lifting wire winding device are oppositely and movably arranged on the ground rail and can move closer to or away from each other to clamp or loosen a wide wire reel accordingly. The first movable lifting wire winding device includes a first traveling crane and a first top cone lifting mechanism, and the first top cone lifting mechanism is arranged on the first traveling crane. The second movable lifting wire winding device includes a second traveling crane, a second top cone lifting mechanism and a wire winding mechanism. The second wire winding mechanism is arranged on the second traveling crane through the second top cone lifting mechanism and is driven by the second top cone lifting mechanism to move up and down relative to the second traveling crane. This patent document uses two traveling cranes to drive the two movable lifting wire winding devices to move closer to or away from each other on the ground rail to clamp or loosen a wide wire reel accordingly, which is not limited by the width of the wire reel and has a wide application range. However, the two traveling cranes (the first traveling crane and the second traveling crane) work independently, and it is easy to cause the moving speeds of the two traveling cranes to be inconsistent due to problems such as wear and different frictional resistances, resulting in the wire reel being prone to looseness, and further reducing the working stability during wire winding and unwinding. Therefore, the defect is very obvious and a solution is urgently needed. Content of the Utility Model

[0016] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the drawings. The content mentioned in the embodiments does not limit the present utility model.

[0017] As Figures 1 to 4 shown, an axle row wire winding and unwinding machine provided by the present utility model includes two parallel guide rails 1, a first support 2 movably arranged on the two guide rails 1, a second support 3 movably arranged on the two guide rails 1 and opposite to the first support 2, an opening and closing drive mechanism 4 connecting the top of the first support 2 and the top of the second support 3, a first lifting block 5 liftably arranged in the middle of the first support 2, a first top head 6 rotatably arranged on the first lifting block 5, a second lifting block 7 liftably arranged in the middle of the second support 3, a second top head 8 rotatably arranged on the second lifting block 7, a wire winding and unwinding rotation drive mechanism 9 installed on the second lifting block 7 and used to drive the second top head 8 to rotate, a first lifting drive mechanism 10 installed on the first support 2 and used to drive the first lifting block 5 to lift, a second lifting drive mechanism 11 installed on the second support 3 and used to drive the second lifting block 7 to lift, a rack 12 arranged side by side on one side of the guide rail 1, two first rollers 13 rotatably connected to the bottom of the first support 2, two second rollers 14 rotatably connected to the bottom of the second support 3, a gear 15 coaxially installed on the first roller 13, and a travel rotation drive mechanism 16 installed on the bottom of the first support 2. The first top head 6 and the second top head 8 are arranged opposite to each other. The opening and closing drive mechanism 4 is used to drive the first support 2 and the second support 3 to approach or move away from each other. The two first rollers 13, the two second rollers 14 and the two guide rails 1 are respectively arranged in one-to-one correspondence. The two first rollers 13 and the two second rollers 14 all roll along the two guide rails 1. The travel rotation drive mechanism 16 is used to drive the first roller 13 and the gear 15 to rotate. The gear 15 meshes with the rack 12 for transmission.

[0018] This embodiment will be described by taking the wire take-up as an example; in practical applications, when installing the wire reel, the wire reel is rolled between the first support 2 and the second support 3, so that the first top head 6 and the second top head 8 are respectively aligned with the central holes of the wire reel. Then, the opening and closing drive mechanism 4 drives the first support 2 and the second support 3 to approach each other until the first top head 6 and the second top head 8 are respectively inserted into both ends of the central hole of the wire reel and clamp the wire reel. Then, the first lifting drive mechanism 10 drives the first lifting block 5 to lift together with the first top head 6. At the same time, the second lifting drive mechanism 11 drives the second lifting block 7 to lift and lower together with the second top head 8, so that the first top head 6 and the second top head 8 cooperate to lift the wire reel and leave the bottom surface. Then, the free end of the cable to be taken up is wound around the wire reel. The winding and unwinding rotation drive mechanism 9 drives the second top head 8 to rotate. The rotating second top head 8 cooperates with the first top head 6 to drive the wire reel to rotate synchronously. The rotating wire reel winds the cable. During the process of taking up the wire on the wire reel, the traveling rotation drive mechanism 16 drives the first roller 13 and the gear 15 to rotate forward or backward. The rotating gear 15 meshes with the rack 12, so that the gear 15 reciprocates along the rack 12. The reciprocating gear 15 drives the first roller 13 to reciprocate along the guide rail 1, thereby causing the first support 2 to reciprocate. The reciprocating first support 2 drives the second support 3 to reciprocate synchronously via the opening and closing drive mechanism 4, so that the wire reel reciprocates, realizing the shaft row wire take-up of the wire reel and making the wound cable of the wire reel neater. When the wire reel needs to be replaced, the first lifting drive mechanism 10 and the second lifting drive mechanism 11 respectively drive the first lifting block 5 and the second lifting block 7 to descend, so that the first top head 6 and the second top head 8 drive the wire reel to descend. Until the ground supports the wire reel, the opening and closing drive mechanism 4 drives the first support 2 and the second support 3 to move away from each other, so that the first top head 6 and the second top head 8 are removed from the central holes of the wire reel to release the wire reel, and the wire reel can be removed. Among them, the opening and closing drive mechanism 4 can not only drive the first support 2 and the second support 3 to approach or move away from each other, but also realizes the connection between the first support 2 and the second support 3, improves the structural stability, and ensures the synchronous movement of the first support 2 and the second support 3. The structure of the utility model has good stability, is especially suitable for carrying wire reels with large weights, and the movement synchronization of the first support 2 and the second support 3 is good, there is no speed difference, the movement stability is good, the wire arrangement is more stable, and the winding and unwinding are neater.

[0019] In this embodiment, the two first rollers 13 are connected via a first connecting shaft 17; the two second rollers 14 are connected via a second connecting shaft 18. This structural design ensures the synchronous rolling of the two first rollers 13 and the two second rollers 14.

[0020] In this embodiment, the walking and rotating drive mechanism 16 includes a walking motor 19, a walking speed reducer 20 and a transmission component 21. The walking motor 19 and the walking speed reducer 20 are both installed at the bottom of the first support 2. The output shaft of the walking motor 19 is drivingly connected to the input end of the walking speed reducer 20, and the output end of the walking speed reducer 20 is drivingly connected to the first connecting shaft 17 via the transmission component 21. In practical applications, the walking motor 19 drives the first connecting shaft 17 to rotate via the walking speed reducer 20 and the transmission component 21. The rotating first connecting shaft 17 drives the first roller 13 and the gear 15 to rotate. The rotating first roller 13 rolls along the guide rail 1, and the rotating gear 15 meshes with the rack 12, so that the gear 15 meshes with and moves along the rack 12.

[0021] In this embodiment, the opening and closing drive mechanism 4 is a cylinder or an oil cylinder.

[0022] Specifically, both the first lifting drive mechanism 10 and the second lifting drive mechanism 11 can adopt existing lead screw modules; the winding and unwinding rotation drive mechanism 9 can adopt a rotation driver in the prior art, such as a motor, etc.; the transmission component 21 can be composed of a transmission chain and a sprocket, or can be composed of a transmission belt and a transmission wheel.

[0023] All the technical features in this embodiment can be freely combined according to actual needs.

[0024] The above embodiments are the preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
