Description

A wire feeding device for overhead crane lines Technical Field

[0001] This utility model belongs to the technical field of wire laying equipment, specifically relating to a wire laying device for overhead crane wire laying. Background Technology

[0002] Overhead cranes are material handling equipment commonly used in logistics settings such as factories, warehouses, docks, and railway stations. In overhead crane systems used for transporting stainless steel wire, the wire feeding device causes the wire to swing violently during high-speed feeding, affecting feeding efficiency and posing safety risks. Summary of the Invention

[0003] Based on the background technology, to solve the problem of violent swinging of stainless steel wire during high-speed wire feeding, this utility model provides a wire feeding device for overhead cranes, comprising a wire feeding frame, a cylindrical cover, and a wire feeding guide cone. The wire feeding frame is placed inside the cylindrical cover and is vertically arranged. Stainless steel wire is wound on the wire feeding frame. The wire feeding guide cone is fixedly connected to the top of the cylindrical cover and communicates with the interior of the cylindrical cover. A wire feeding hole is opened on the top of the wire feeding guide cone. When the stainless steel wire on the wire feeding frame passes through the wire feeding hole of the wire feeding guide cone and is fed at high speed under traction, the cylindrical cover and the wire feeding guide cone can limit the swinging range of the stainless steel wire, improve the wire feeding efficiency, and the cylindrical cover can also form a relatively sealed space to prevent the swinging stainless steel wire from injuring workers, resulting in a high safety factor.

[0004] Furthermore, it also includes a first pressure ring and a second pressure ring, which are respectively disposed on the upper and lower sides of the wire feeding frame. The first pressure ring is located on one side of the wire feeding guide cone cover. The first pressure ring and the second pressure ring are specifically connected to the wire feeding frame through branch pipes. The arrangement of the first pressure ring and the second pressure ring ensures that the stainless steel wire will not detach when it is wound on the wire feeding frame.

[0005] Furthermore, a limiting ring is also provided inside the wire feeding guide cone, and the limiting ring is also fixedly connected to the first pressure ring through a branch pipe. The limiting ring is coaxial with the wire feeding hole of the wire feeding guide cone. The stainless steel wire first passes through the limiting ring and then exits from the wire feeding hole of the wire feeding guide cone. This limiting ring design can further reduce the swing range of the stainless steel wire, so that the swing range is gradually reduced within the wire feeding guide cone to make the wire feeding smooth and improve the wire feeding efficiency.

[0006] Furthermore, a straightening mechanism is also provided above the wire feeding guide cone. Specifically, a bracket is connected to the top of the wire feeding guide cone, and the straightening mounting plate of the straightening mechanism is connected to the bracket. The straightening mechanism includes a first straightening wheel group, a second straightening wheel group, a straightening mounting plate, an adjusting slider, a compression spring, and an adjusting screw. The first straightening wheel group and the second straightening wheel group are arranged opposite to each other.

[0007] The first straightening wheel assembly includes a plurality of first straightening wheels arranged vertically in sequence, and the first straightening wheels are rotatably connected to the straightening mounting plate;

[0008] The second straightening wheel assembly includes a series of vertically arranged second straightening wheels, each rotatably connected to a corresponding adjusting slider. The straightening mounting plate has an elongated hole at the corresponding position of the second straightening wheel. The adjusting slider is fitted into the elongated hole, specifically through a groove that engages with the elongated hole, allowing it to slide within the corresponding hole. A compression spring is also provided between the side of the adjusting slider and the inner wall of the corresponding elongated hole. A threaded through-hole is provided on the other side of the elongated hole, and an adjusting screw is screwed into the threaded through-hole. The end of the adjusting screw presses against the adjusting slider. This straightening mechanism allows adjustment of the left and right positions of the second straightening wheels via the adjusting screw, enabling it to adapt to stainless steel wires of different thicknesses. When the stainless steel wire is wound on the pay-off frame, it may experience severe bending; this straightening mechanism can straighten this bending, ensuring stable transmission of the released wire.

[0009] Preferably, the shroud is composed of a first half-cylinder and a second half-cylinder. One side of the first half-cylinder is hinged to one side of the second half-cylinder, and a locking bar is fixedly connected to the other side of the first half-cylinder. A locking buckle is hinged to the other side of the second half-cylinder at a corresponding position. The locking bar and the locking buckle can cooperate to lock each other. This structural design allows the shroud to be opened and closed. The wire feeding frame is mounted on a mobile trolley. After the wire feeding is completed, the wire feeding frame can be pushed out for replacement after the shroud is opened, which can improve the material changing efficiency. The mobile trolley of the wire feeding frame can be positioned inside the shroud by a pin.

[0010] Through the above technical solutions, this utility model has at least the following beneficial effects:

[0011] The wire feeding device for the overhead crane production line described in this application, through the design of a cylindrical cover and a wire feeding guide cone, can limit the swing range of the stainless steel wire, thereby improving the wire feeding efficiency. The cylindrical cover also forms a relatively enclosed space, preventing the swinging stainless steel wire from injuring workers, thus ensuring a high safety factor. In a further embodiment, the design of the limiting ring can further reduce the swing range of the stainless steel wire, allowing it to gradually shrink within the wire feeding guide cone to ensure smooth wire feeding and improve efficiency. A straightening mechanism is also provided above the wire feeding guide cone to correct the bending of the wire, ensuring stable transmission of the fed wire. In a preferred embodiment, the openable and closable design of the cylindrical cover and the movable setting of the wire feeding frame can improve the material changing efficiency of the wire feeding device.

The wire feeding guide cone 3 is fixedly connected to the top of the cylindrical cover 2 and communicates with the interior of the cylindrical cover 2. A wire feeding hole 301 is provided on the top of the wire feeding guide cone 3. When the stainless steel wire on the wire feeding frame 1 passes through the wire feeding hole 301 of the wire feeding guide cone 3 and is fed at high speed under traction, the cylindrical cover 2 and the wire feeding guide cone 3 can limit the swing range of the stainless steel wire, improve the wire feeding efficiency, and the cylindrical cover 2 can also form a relatively closed space to prevent the swinging stainless steel wire from injuring the workers, resulting in a high safety factor.

[0023] Referring to Figure 4, the wire feeding device of the overhead crane line also includes a first pressure ring 4 and a second pressure ring 5. The first pressure ring 4 and the second pressure ring 5 are respectively disposed on the upper and lower sides of the wire feeding frame 1. The first pressure ring 4 is located on one side of the wire feeding guide cone cover 3. The first pressure ring 4 and the second pressure ring 5 are specifically connected to the wire feeding frame 1 through branch pipes. The arrangement of the first pressure ring 4 and the second pressure ring 5 ensures that the stainless steel wire will not detach when it is wound on the wire feeding frame 1.

[0024] Referring to Figure 5, a limiting ring 6 is also provided inside the wire feeding guide cone 3. The limiting ring 6 is also fixedly connected to the first pressure ring 4 through a branch pipe. The limiting ring 6 is coaxial with the wire feeding hole 301 of the wire feeding guide cone 3. The stainless steel wire first passes through the limiting ring 6 and then exits from the wire feeding hole 301 of the wire feeding guide cone 3. The design of the limiting ring 6 can further reduce the swing range of the stainless steel wire, so that the swing range is gradually reduced within the wire feeding guide cone 3 to make the wire feeding smooth and improve the wire feeding efficiency.

[0025] In a further embodiment, referring to Figures 2 and 3, a straightening mechanism 7 is also provided above the wire feeding guide cone 3. Specifically, a bracket is connected to the top of the wire feeding guide cone 3, and the straightening mounting plate 703 of the straightening mechanism 7 is connected to the bracket. The straightening mechanism 7 includes a first straightening wheel group, a second straightening wheel group, a straightening mounting plate 703, an adjusting slider 704, a compression spring 705, and an adjusting screw 706.

[0026] The first straightening wheel group includes a plurality of first straightening wheels 701 arranged vertically in sequence, and the first straightening wheels 701 are rotatably connected to the straightening mounting plate 703;

[0027] The second straightening wheel assembly includes a series of vertically arranged second straightening wheels 702, each of which is rotatably connected to a corresponding adjusting slider 704. The straightening mounting plate 703 has an elongated hole 707 at a corresponding position of the second straightening wheel 702. The adjusting slider 704 is fitted into the elongated hole 707. Specifically, the adjusting slider 704 engages with the elongated hole 707 via a groove, allowing it to slide within the corresponding elongated hole 707. A compression spring 705 is also provided between one side of the adjusting slider 704 and the inner wall of the corresponding elongated hole 707.

The end of the adjusting screw 706 presses against the adjusting slider 704. The straightening mechanism 7 described above can adjust the left and right positions of the second straightening wheel 702 by adjusting the screw 706, so that the straightening mechanism 7 can adapt to stainless steel wires of different thicknesses; when the stainless steel wire is wound on the wire feeding frame 1, it will be severely bent, and the straightening mechanism 7 can straighten the bend, so that the wire can be transmitted stably.

[0028] In a preferred embodiment, referring to FIG4, the shroud 2 is composed of a first half-cylinder 201 and a second half-cylinder 202.
