Description

Technical Field

[0001] The utility model relates to the technical field of cranes, and in particular to a cable management device for cranes. Background Art

[0002] A crane is a machine capable of lifting and transporting heavy objects vertically within a certain range. Gantry cranes are a type of crane. Gantry cranes primarily use an electric hoist to move heavy objects horizontally, connected to a power cable. Existing gantry cranes are equipped with a wire rope. The cables connected to the electric hoist are connected to the wire rope via multiple cable pulleys to organize the cables, preventing them from becoming tangled when moving synchronously with the electric hoist. As the electric hoist moves, the cables drive the cable pulleys on the wire rope, allowing the cables to be moved or stored in sections.

[0003] After a gantry crane has been in use for a long time, dust and lint in the air will accumulate on the wire rope, the cable pulley, and even the rotating shaft of the cable pulley, causing greater friction resistance when the cable pulley moves on the wire rope. During the movement of the cable pulley, the cable needs to be driven by the cable to move. As a result, when the electric hoist moves, it needs to apply a large pulling force to the cable to drive the cable pulley to move, resulting in greater stress at the contact point between the cable and the cable pulley. If this continues for a long time, the cable sheath will be damaged at the contact point with the cable pulley, affecting the operation of the gantry crane. Utility Model Content

[0005] Optionally, the connecting and driving assembly further includes a winding drum, the driving motor is connected to the winding drum and is suitable for driving the winding drum to rotate, and the thin steel wire rope is suitable for being wound around the winding drum.

[0006] Optionally, a connecting column is provided on the outer wall of the suspension wire pulley body, and one end of the thin steel wire rope away from the driving motor is tied to the connecting column adjacent to the suspension wire pulley body.

[0007] Optionally, an annular groove is provided on the outer wall of the connecting column, and the end of the thin steel wire rope away from the driving motor is tied to the annular groove.

[0008] Optionally, the suspension pulley body includes a connecting seat, a rotating pulley and a cable clamping block, the rotating pulley is rotatably connected to the connecting seat, the cable clamping block is connected to the connecting seat, two cable clamping blocks are symmetrically arranged, the two cable clamping blocks are connected by bolts, and the cable is passed through the two cable clamping blocks.

[0009] Optionally, a first wire threading groove that is interconnected is provided on one side of the two cable clamping blocks that are close to each other, the cable is passed through the first wire threading groove, and the flexible layer is provided in the first wire threading groove.

[0010] Optionally, the two cable clamping blocks are each provided with a second wire threading groove that is interconnected on one side, the second wire threading groove is arranged at intervals with the first wire threading groove, the inner diameter of the second wire threading groove is smaller than the inner diameter of the first wire threading groove, and the flexible layer is also provided in the second wire threading groove.

[0012] Optionally, both ends of the flexible layer in the first wire threading groove and the second wire threading groove along the cable threading direction protrude from the cable clamping blocks.

[0013] Optionally, each of the drive motors can operate independently.

[0014] Compared with the prior art, the beneficial technical effects of the present invention are:

[0015] 1. When the electric hoist is moving, the cable pulley body will move and comb the cables connected to the electric hoist. After the cable pulley body moves a certain length, it will drive the other adjacent cable pulley body to move through the connecting driving component, so that the cable pulley body drives the cable to move, and the cable between the two adjacent cable pulley bodies remains in a falling state and is not affected by the tension, so that the contact between the cable and the cable pulley body is not easily worn and broken due to large stress;

[0016] 2. The first and second threading grooves for the cables are both arc-shaped grooves. The ends of the cables protruding from the first or second threading grooves will sag under the action of gravity. In this state, the cables can better fit into the arc-shaped grooves. Compared with straight grooves, the edges of the arc-shaped threading grooves are less likely to cause greater stress on the cables, making the cables less likely to be damaged during the movement and combing process of the cable pulley body.

[0017] 3. During the return stroke of the electric hoist, the corresponding drive motor will drive the corresponding winding drum to rotate so that the thin steel wire rope is wound on the winding drum, and then pull the adjacent and close to the electric hoist to move the cable pulley body to comb the cable. The whole process is still driven by the cable pulley body to move the cable. The cable pulley body itself bears a large tensile force, which further protects the cable.

[0018] 4. The setting of the connecting column enables the thin steel wire rope to maintain a relatively horizontal state with the winding drum after being tied, and can exert a relatively horizontal pulling force when driving the adjacent suspension pulley body to move, ensuring the smoothness of the suspension pulley body after being pulled. At the same time, the thin steel wire rope is tied in the ring groove, making it difficult for the thin steel wire rope to detach from the connecting column, thereby improving the stability of the connecting rope after installation;

[0019] 5. The diameters of the first threading groove and the second threading groove are different, so the cable pulley body can be used to install cables of two different diameters. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] In the description of the present invention, it should be understood that the terms "upper" and "lower" and the like indicate positions or location relationships based on the positions or location relationships during normal use of the product.

[0026] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0027] The following is combined with Figure 1-3 This application is described in further detail.

[0028] The utility model provides a crane cable management device, referring to Figure 1 and Figure 2 The crane cable management device includes a wire pulley body 1 and a connecting and driving assembly 2. The wire pulley body 1 is suitable for sliding installation on the wire rope of the gantry crane. There are multiple wire pulley bodies 1, and the multiple wire pulley bodies 1 are all slidingly connected to the wire rope of the gantry crane and arranged at intervals. The gantry crane is slidingly provided with an electric hoist for lifting heavy objects, and the electric hoist is connected to a cable. The multiple wire pulley bodies 1 are all sleeved on the cable connection and clamped to fix the cables. A connecting and driving assembly 2 is installed on each wire pulley body 1. When one of the two adjacent wire pulley bodies 1 moves a certain length along with the electric hoist, the corresponding wire pulley body 1 will drive the other wire pulley body 1 to move through the connecting assembly. At this time, the cable between the two adjacent wire pulley bodies 1 is in a loose and falling state.

[0029] It is worth noting that in addition to the end of the cable being electrically connected to the electric hoist, the cable is also fixedly installed on the electric hoist. When the electric hoist moves, this part drives the suspension pulley body 1 to move on the wire rope, thereby preventing the electrical connection between the cable end and the electric hoist from loosening.

[0030] Reference Figure 2 and Figure 3 The cable pulley body 1 includes a connecting seat 11, a rotating pulley 12, and a cable clamping block 13. The rotating pulley 12 is rotatably connected to the connecting seat 11 and can move on the wire rope of the gantry crane. The cable clamping block 13 is connected to the connecting seat 11. Two cable clamping blocks 13 are symmetrically provided and connected by bolts. The cable is passed between the two cable clamping blocks 13 and is clamped and fixed by the two cable clamping blocks 13.

[0031] A pulley groove is defined in the sidewall of the connection base 11, extending through the connection base 11 and extending through the top of the connection base 11. A rotating pulley 12 is positioned within the groove and rotatably connected to the connection base 11 via a rotating pin. A connecting groove is defined at the bottom of the connection base 11, into which the top ends of two cable clamping blocks 13 are inserted and mounted to the connection base 11 via bolts.

[0032] Reference Figure 2 and Figure 3 The two cable clamping blocks 13 are each provided with a first threading groove 131 and a second threading groove 132 on the side adjacent to each other. The first threading grooves 131 and the second threading grooves 132 are spaced apart. The first threading grooves 131 on the two cable clamping blocks 13 are interconnected; the two second threading grooves 132 are also interconnected. The inner diameter of the first threading groove 131 is larger than that of the second threading groove 132, thus accommodating cables of two different diameters.

[0033] The first and second threading grooves 131, 132 are both arc-shaped grooves, with the tops of the arcs of the first and second threading grooves 131, 132 facing the rotating pulley 12. The ends of the cable protruding from the first or second threading grooves 131, 132 will sag under the action of gravity. In this state, the cable fits better in the arc-shaped grooves, and stress concentration caused by the outer edges of the first and second threading grooves 131, 132 is less likely to occur.

[0034] Reference Figure 2 and Figure 3 A flexible layer 133 is fixedly provided in each of the two first threading grooves 131 and the two second threading grooves 132. The flexible layer 133 is made of rubber material. After the cable passes through the first threading groove 131 or the second threading groove 132, the flexible layer 133 can wrap the cable, thereby reducing the wear at the contact point between the cable and the cable clamping block 13.

[0035] The flexible layer 133 in the first and second wire threading grooves 131, 132 protrudes from the cable clamping block 13 at both ends along the cable threading direction. This arrangement allows the ends of the cable protruding from the cable clamping block 13 to form a flexible contact with the cable clamping block 13, reducing the stress on the cable at this point and making it less likely to break.

[0036] Reference Figure 2 and Figure 3The connecting and driving component 2 includes a driving motor 21, a thin steel wire rope 22 and a winding drum 23. A supporting plate is fixedly mounted on the outer wall of the cable clamping block 13, and the driving motor 21 is fixedly mounted on the supporting plate. The winding drum 23 is sleeved on the rotating shaft of the driving motor 21 and rotates synchronously with the rotating shaft of the driving motor 21. One end of the thin steel wire rope 22 is fixed on the winding drum 23 and can be wound around the winding drum 23 or unwound from the winding drum 23 as the driving motor 21 rotates. A connecting column 24 is fixedly mounted on the outer wall of the cable clamping block 13 on which the supporting plate is set. The end of the thin steel wire rope 22 away from the driving motor 21 is tied to the connecting column 24 of the adjacent suspension pulley body 1 to drive the adjacent suspension pulley body 1 to move. When the thin steel wire rope 22 between two adjacent suspension pulley bodies 1 is in a fully unfolded and taut state, the cable between the corresponding two adjacent suspension pulley bodies 1 is in a relaxed and falling state.

[0037] An annular groove 241 is provided on the outer wall of the connecting column 24, and the end of the thin steel wire rope 22 away from the driving motor 21 is tied to the annular groove 241 of the connecting column 24 on the other suspension pulley body 1, so that the thin steel wire rope 22 is not easy to detach from the connecting column 24, thereby improving the stability of the steel wire rope after being connected to the connecting column 24.

[0038] It is worth noting that each driving motor 21 can operate independently, so that each section of cable can be relatively independent when moving and combing.

[0039] The implementation principle of a crane cable management device in an embodiment of the present application is: when the electric hoist is on the outward journey, the wire pulley body 1 closest to the electric hoist will be driven and move on the wire rope on the gantry crane. At this time, the driving motor 21 on the adjacent wire pulley body 1 will rotate to make the wire rope unfolded. When the thin wire rope 22 is fully unfolded and taut, the cable between the two adjacent wire pulley bodies 1 is in a relaxed and falling state.

[0040] During the hoist's return journey, the drive motor 21 on the next closest cable pulley 1 drives the thin steel wire rope 22 to wind around the winding drum 23, moving the cable pulley closest to the hoist. This process repeats for each subsequent cable pulley 1. Throughout this process, the thin steel wire rope 22 drives the corresponding cable pulley 1 to move and organize the cables, preventing them from being damaged and potentially affecting the gantry crane.

[0041] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present utility model.
