Description

Technical Field

[0001] The invention relates to the technical field of finished product warehousing and warehousing logistics of cable enterprises, and specifically is a lifting and transferring device for coiled cable products. Background Art

[0002] Cable is a general term for reels of cables, such as optical and electrical cables. Cables have numerous uses, primarily controlling installations, connecting devices, and transmitting power, making them a common and essential part of everyday life. Finished cables are typically stored and transported on reels. Existing cable storage methods primarily involve lifting cables using electric hoists on gantry cranes or manually rolling cables to storage yards. This approach is difficult to achieve safe and efficient operation in large storage facilities. This is particularly true for reels stored at high altitudes in rack-type warehouses, making this method impractical. Summary of the Invention

[0003] The present invention proposes a new lifting and transporting device to solve the above problems, which is specifically as follows.

[0004] A device for lifting and transferring coiled cable products comprises a gantry and a gondola, wherein the gondola is connected to the gantry and the gantry moves along a ground track; the moving direction of the gantry is assumed to be the x-direction, the length direction of the gantry's crossbeam is the y-direction, and the vertical direction is the z-direction; the x-direction, y-direction and z-direction are perpendicular to each other and correspond to the three coordinate axes of a spatial coordinate system xyoz respectively; the gondola is connected to the gantry.

[0005] The connection structure between the gondola and the gantry is as follows: the gantry is provided with a ceiling rail (a track on the gantry beam), which is parallel to the y-direction; a traveling overhead crane is connected to the ceiling rail; a lifting column is vertically connected to the overhead crane and can be raised and lowered in the z-direction; the gondola is rotatably connected to the bottom of the lifting column, and the rotation axis is parallel to the z-direction;

[0006] The structure of the gondola comprises a car body, wherein a hollow cavity is provided in the car body for accommodating the cable coil, both ends of the cavity are connected, and the axis of the cavity is parallel to the plane xoy of the space coordinate system xyoz;

[0007] Two telescopic forks in pairs are arranged in the cavity, and the telescopic direction of the forks is parallel to the axial direction of the cavity.

[0008] --Because the reeled cable is wound around the reel, the overall shape is cylindrical. The side panels of the reel are on both end faces of the cylinder, and the diameter of the side panels is larger than the diameter of the cylinder. Normally, the reel is in a lying position, that is, the axis of the reel is parallel to the ground. The hoisting car arrives at a position next to the reel and rotates so that the axis of the cavity is parallel to the axis of the reel. Two forks are extended to the bottom of the reel. Because the reel is in a lying position, the two sides of the position where it contacts the ground are suspended, and the forks can just be inserted into the positions on both sides.

[0009] After the fork is inserted, the lifting column lifts the car body slightly to lift the wire reel off the ground; then the fork plate retracts into the car body to make the wire reel completely inside the cavity of the car body; the car body is delivered to the destination under the action of the gantry and the overhead crane and lifting column on it.

[0010] After arriving at the destination, repeat the above process in reverse and place the reel at the destination.

[0011] The flexible movement of the crane allows the reel to be placed and retrieved at multiple locations. When the reel is inside the crane, its axis is parallel to the ground, and two forks at the bottom on either side of the axis prevent it from rolling inside the crane.

[0012] The telescopic forks can be made from existing components.

[0013] Specifically, the box body is composed of a steel frame with a steel plate skin attached to the outside of the frame. The top, bottom and two side surfaces of the box body are closed. The sturdy structure is used to limit and protect the wire reels in transit.

[0014] One improvement is that the two forks are inclined, and on the radial cross section of the forks, the two forks are in an inverted "eight" shape.

[0015] Because the wire reel is cylindrical and the side panels are pancake-shaped, using horizontal forks would minimize contact between the forks and the side walls or edges of the reel, creating high pressure and easily causing damage. Therefore, this structure allows the weight of the wire reel to form two components: one perpendicular to the fork surface and one parallel to it. This reduces pressure at the point of contact and minimizes damage.

[0016] Another improvement is that the two forks are rotatable around their respective telescopic directions, and the structure includes a telescopic fork assembly and an adaptive support structure;

[0017] For any telescopic fork assembly: the adaptive support structure includes an elastic support column; one side of the bottom surface of the telescopic fork assembly is rotatably connected to the frame on the bottom surface of the vehicle body, and the rotation axis is parallel to the extension and retraction direction of the fork; the other side of the bottom surface of the telescopic fork assembly is connected to the elastic support column between the frame on the bottom surface of the vehicle body;

[0018] The elastic support columns of the two adaptive support structures are close to each other.

[0019] ——Under this structure, the fork plate can rotate axially and adapt to the circumference of the wire drum.

[0020] Under normal circumstances, the telescopic fork assembly is in a horizontal state; when the fork is lifting the wire drum, since the wire drum is located at a lower position close to its axis, the side plate of the wire drum presses the telescopic fork of the telescopic fork assembly into an inverted "eight" shape, and accordingly, the telescopic fork assembly as a whole is in an inverted "eight" shape.

[0021] Compared with the fixed horizontal fork or the above-mentioned inclined fork, the inclination angle of the fork under this structure can be adaptively adjusted according to the diameter of the wire drum, further reducing the contact pressure between the fork and the side plate of the wire drum.

[0022] With the above two improvements, an elastic rubber layer can be attached to the surface of the fork to play a role in buffering and increasing friction.

[0023] Specifically, there are two elastic support columns, which are arranged along the telescopic direction of the fork and located at the head and tail ends of the bottom surface of the telescopic fork assembly to increase operational stability. The elastic support columns are spring pressure rods, pneumatic rods or hydraulic rods.

[0024] Furthermore, the gantry is composed of two sets of columns connected by beams; the beams are parallel to each other, and parallel overhead rails are connected to the two beams. The overhead crane travels along the two overhead rails, and the lifting column passes vertically between the two beams.

[0025] Any group of columns has two pillars, and the top of one pillar is connected to the end of a beam; the bottom distance between the two pillars in the same group is greater than the top distance, and the bottoms of the two pillars are connected to the head and tail ends of the same bottom longitudinal beam, and the bottom surface of the longitudinal beam is connected to the walking wheel.

[0026] The two beams are connected at their ends by reinforcing rods. The two beams and the two reinforcing rods form a hollow space that forms the overhead crane's travel area. The travel wheels are driven by a motor.

[0027] Furthermore, a hollow is opened in the middle of the overhead crane for installing the lifting column, and a guide frame is connected around the hollow;

[0028] The lifting column comprises an inner lifting column and an outer lifting column. In the radial cross section of the lifting column, the inner lifting column and the outer lifting column are both rectangular (preferably square). The outer lifting column is sleeved outside the inner lifting column. Corresponding pulleys and Z-direction slide rails are provided between each inner wall of the outer lifting column and the corresponding outer wall of the inner lifting column. The bottom surface of the inner lifting column is rotatably connected to the gondola.

[0029] The outer lifting column is in the guide frame, each outer wall of the outer lifting column is provided with a Z-direction slide rail, and the guide frame is provided with a corresponding pulley.

[0030] To prevent the lifting column from being too high above the gantry when raised, a two-stage lifting column structure was adopted. Furthermore, due to the heavy weight of the gondola and the suspended cable drum, and the fact that it moves while suspended, a slide rail / pulley structure was used between the two-stage lifting column structure and the guide frame to ensure smooth sliding and improve safety.

[0031] The lifting of the inner and outer lifting columns can be powered by a winch. At least two winches should be used, and the force applied to the hoist box by the cables / chains of each winch must be balanced. The main body of the winch can be mounted on an overhead crane.

[0032] The bottom surface of the inner lifting column and the rotation connection of the hanging car can be realized by a slewing bearing (turntable bearing) structure. The power source of the rotation can be a motor, and the main body of the motor is installed on the top surface of the hanging car.

[0033] The device facilitates the transfer of cable reels during large-scale cable storage, improves efficiency and safety, and reduces labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS
