Description

Technical Field

[0001] The present invention relates to the field of cable conveying equipment, and specifically to a drum device for cable conveying. Background Art

[0002] A cable drum is a cable winding device that provides power supply, control power supply or control signal for large mobile equipment, and is widely installed on the gantry of heavy machinery and equipment such as port portal cranes, container cranes, ship loaders, tower cranes, etc. At present, cable drums are mainly divided into electric cable drums and non-electric cable drums according to the driving form.

[0003] The working principle of the spring-driven cable drum in the non-electric cable drum is as follows: when the cable is pulled out, the volute spring is tightened to store energy, and when the external force is removed, the spring releases energy, and the drum will automatically wind up the cable. Therefore, in order to prevent too much cable from being wound on the cable drum, in actual use, the cable is usually tied to the middle position of the maximum moving stroke of the gantry, so that when the gantry moves to the left and right sides, the cable drum releases the cable; when moving to the middle position of the maximum moving stroke of the gantry, the cable drum winds up the cable.

[0004] However, when the gantry drives the cable drum to move to the left and right sides, the gantry drives the cable drum to move synchronously, causing the cable to pull the cable drum to rotate. When the gantry stops, the inertia of the cable drum itself will cause it to continue to rotate, thus releasing the excess cable. When the volute spring then drives the drum to rotate in the reverse direction and wind up the cable, the rotation speed of the drum is too fast, pulling the cable and damaging it. In addition, when the gantry traverses and crosses the midpoint of its maximum stroke, the cable pulls the drum to quickly change from the winding state to the unwinding state, and at this time, the cable on the drum is the most, making the rotational inertia of the drum larger, so that the impact on the cable caused by the drum is greater, and it is easy to damage the cable. Summary of the Invention

The conical sleeve connected to the movable plate on the rear side is slidably sleeved on the outside of the guide tube at the corresponding position, and the conical sleeve connected to the movable plate on the front side is fixedly sleeved on the front outside of the guide tube at the corresponding position.

[0013] Preferably, the deceleration assembly includes a sliding rod which is slidably arranged at the rear of the mobile frame, a fixed block is fixedly installed on the upper part of the sliding rod, a friction block is slidably arranged on the fixed block, a rotating disk which rotates synchronously with the reel body is arranged at the position of the reel body corresponding to the friction block, and a pushing spring is arranged between the fixed block and the mobile frame.

[0017] The beneficial effects of the present invention are as follows: 1. The present invention adopts a clamping assembly to clamp the cable, so that the movable frame limits the cable through the clamping assembly, so that when the reel body quickly pulls the cable, the cable is straightened and pushes the movable frame to move upward and compress the buffer spring, and then the elastic force of the buffer spring prevents the cable from being suddenly straightened, thereby preventing the cable from being damaged due to rapid pulling when straightened.

[0018] Second, the present invention adopts a deceleration component to decelerate the rotation of the drum body while the drum body is pulling the cable to straighten it, thereby slowing down the rotation speed of the drum body, thereby preventing the drum body from rotating quickly and pulling the cable, and further preventing damage to the cable.

[0019] 3. The present invention adopts a lifting assembly that can push the sliding part upward to drive the arc block to rest against the follower disk when the gantry moves horizontally and passes the midpoint of its maximum stroke, so that the drum body drives the arc block to compress the coil spring through the follower disk, and then the rotation of the drum body is decelerated by the elastic force of the coil spring that gradually increases when it is compressed. Subsequently, the coil spring can also push the drum body to pre-start reversal, so that the drum body actively changes from the winding state to the unwinding state, thereby avoiding the drum body from causing a large impact on the cable, and further preventing the cable from being damaged.

[0020] Fourth, the present invention adopts a moving component that can drive the cable to be wound around the reel body layer by layer through the movement of the cable, thereby avoiding the phenomenon of cables overlapping and winding with each other, so that the winding and unwinding of the cable can be smoother, thereby preventing the cable from being pulled due to jamming, and further preventing cable damage.

[0031] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0032] See also Figure 1 and Figure 2, A reel device for cable conveyance, comprising a mounting frame 1 fixedly installed on the front side of a gantry. The right side of the mounting frame 1 is in a U-shaped structure, and the left side of the mounting frame 1 is in two plate-like structures arranged vertically and distributed front and back. A spring-driven reel body 2 is provided at the upper part of the plate-like structure of the mounting frame 1. A guiding mechanism 3 for guiding the cable is arranged between the two plate-like structures of the mounting frame 1. The reel device further includes a reversing mechanism 4 for quickly switching the rotation direction of the reel body 2.

[0033] When the cable needs to move along with the gantry, first, the mounting frame 1 is fixedly installed on the front side of the gantry, so that the mounting frame 1 drives the reel body 2 to be synchronously installed on the gantry. Subsequently, the operator winds the cable connected to the electrical equipment around the reel body 2, and then passes the cable wound out of the reel body 2 through the guiding mechanism 3 from top to bottom and connects it to the power supply equipment.

[0034] When the gantry moves in the direction away from the midpoint of its stroke, the cable pulls the reel body 2 to rotate, so that the reel body 2 pays out the cable. When the gantry stops moving, the reel body 2 continues to rotate under the action of inertia, thereby paying out the excess cable. Subsequently, the reel body 2 starts to reverse and wind up through its own elastic force. When the reel body 2 reverses and pulls the cable straight, the guiding mechanism 3 buffers the straightening of the cable to prevent the cable from being pulled by itself due to rapid straightening.

[0035] When the gantry moves in the direction close to the midpoint of its stroke, the reel body 2 reversely winds up the cable through its own elastic force, and at the same time, the guiding mechanism 3 winds the cable layer by layer on the reel body 2 to prevent the cables from being entangled with each other. When the gantry moves to the midpoint position of its stroke, the reel body 2 completely winds up the cable, and at the same time, the reversing mechanism 4 starts to decelerate the rotation of the reel body 2 to prevent the reel body 2 from continuing to wind up under the action of inertia, thereby pulling the cable.

[0036] Subsequently, the reversing mechanism 4 can pre-rotate the reel body 2, so that when the gantry directly passes through the midpoint of its stroke, that is, when the reel body 2 directly changes from winding up to paying out, the reel body 2 can be pre-rotated to pay out the cable in advance, preventing the cable from suddenly pulling the reel body 2 that is winding up, and thus preventing the cable from being pulled and damaged.

[0037] Refer to Figure 1 、 Figure 2 and Figure 3 , The guiding mechanism 3 includes a moving frame 31 that is commonly arranged to slide up and down between the two plate-like structures of the mounting frame 1. A clamping component 33 is arranged inside the moving frame 31 through a moving component 32. The clamping component 33 is used to limit the cable, and the moving component 32 is used to drive the cable to wind around the reel body 2 layer by layer by reciprocating the clamping component 33 back and forth.

[0038] Refer to Figure 1 , Figure 3 and Figure 4 The moving component 32 includes a reciprocating screw 321 fixedly installed on the left side of the moving frame 31, and a roller 323 is provided on the right side of the moving frame 31 through a pushing portion 322. A guide tube 324 is sleeved on the outer sides of the reciprocating screw 321 and the roller 323. The reciprocating screw 321 is threadedly connected to the guide tube 324 thereon, and the roller 323 is slidably connected to the guide tube 324 thereon. The moving component 32 also includes two groups of guide rollers 325 arranged vertically and horizontally inside the moving frame 31, and each group is composed of two guide rollers 325 arranged symmetrically left and right and rotatably set on the moving frame 31.

[0039] See also Figure 4 and Figure 5 The pushing part 322 includes two sliding plates 3221 symmetrically arranged front and back and slidingly set on the moving frame 31. The two sliding plates 3221 are rotatably connected to the roller 323. The right front part of the moving frame 31 is threadedly connected to a No. 1 screw rod 3222, and the left end of the No. 1 screw rod 3222 is rotatably connected to the sliding plate 3221 on the front side.

[0040] See also Figure 3 , Figure 4 and Figure 5 The clamping assembly 33 includes two front-to-rear arranged movable plates 331 which are slidably arranged inside the movable frame 31 through guide columns. Two followers 332 are slidably arranged on the movable plates 331. A conical sleeve 333 is rotatably arranged on one side of the follower 332 located between the two movable plates 331. A No. 2 screw 334 which is threadedly connected to the rear movable plate 331 is rotatably arranged on the front movable plate 331. The conical sleeve 333 connected to the rear movable plate 331 is slidably sleeved on the outer side of the guide tube 324 at the corresponding position, and the conical sleeve 333 connected to the front movable plate 331 is fixedly sleeved on the outer front part of the guide tube 324 at the corresponding position.

[0041] When the cable passes through the drum body 2 to connect the electrical equipment with the power supply equipment, the cable passes through the movable frame 31 from top to bottom, so that the cable is located between the guide rollers 325 on the left and right sides, and the cable is located between the two guide tubes 324, and at the same time, the cable is located between the two movable plates 331. Then the operator manually turns the No. 1 screw 3222, and the No. 1 screw 3222 drives the front sliding plate 3221 to move to the left, and the front sliding plate 3221 drives the right guide tube 324 to move to the left synchronously through the roller 323, so that the right guide tube 324 pushes the cable to press against the left guide tube 324, and then the cable is clamped and limited to the left and right through the two guide tubes 324.

[0042] When the cable is pressed against the guide tube 324, the friction between the guide tube 324 and the cable can be increased, so that when the cable moves, the friction can drive the two guide tubes 324 to rotate synchronously in opposite directions. Then the operator manually rotates the No. 2 screw 334, so that the No. 2 screw 334 drives the two moving plates 331 to approach each other, so that the moving plate 331 drives the conical sleeve 333 to press against the outer surface of the cable through the follower 332, and then the conical sleeve 333 clamps the cable front and back to limit the position, preventing the cable from losing contact with the guide tube 324.

[0043] See also Figure 2 , Figure 6 and Figure 7 A buffer spring is arranged between the movable frame 31 and the mounting frame 1, and the guide mechanism 3 also includes a deceleration assembly 34 for decelerating the reel body 2, and the deceleration assembly 34 includes a sliding rod 341 which is arranged at the rear of the movable frame 31 for sliding up and down movement, and a fixed block 342 is fixedly installed on the upper part of the sliding rod 341, and a friction block 344 is slidably arranged on the fixed block 342, and a rotating disk 343 which rotates synchronously with the reel body 2 is arranged at the position of the reel body 2 corresponding to the friction block 344, and a pushing spring is arranged between the fixed block 342 and the movable frame 31.

[0044] See also Figure 6 and Figure 7 The lower part of the friction block 344 is an inclined surface structure, and the upper part of the friction block 344 is an arc surface structure. A tension spring is arranged between the friction block 344 and the fixed block 342, and the friction block 344 slides on the fixed block 342 along the direction of its inclined surface.

[0045] When the gantry moves away from the midpoint of its stroke, the cable pulls the drum body 2 to rotate clockwise, causing the drum body 2 to start unwinding. When the gantry stops, the drum body 2 continues to rotate under the action of inertia, thereby releasing excess cable. Thereafter, the drum body 2 begins to rotate counterclockwise and rewind due to its own elastic force. When the drum body 2 reverses to pull the cable to straighten it, the straightened cable drives the movable frame 31 to move upward by pushing the guide roller 325 on the lower side, causing the movable frame 31 to compress the buffer spring, gradually increasing the elastic force of the buffer spring, thereby buffering the cable straightening force.

[0046] When the movable frame 31 moves upward, the movable frame 31 pushes the spring so that the fixed block 342 drives the arc surface structure of the friction block 344 to press against the cylindrical surface of the rotating disk 343, and decelerates the rotation of the rotating disk 343 through friction, so that the rotating disk 343 brakes the drum body 2, preventing the drum body 2 from pulling the cable due to rapid winding, thereby further preventing damage to the cable.

[0047] When the cable pulls the drum body 2 to start rotating clockwise for unwinding, the cable is straightened so that the fixed block 342 drives the arc-shaped surface structure of the friction block 344 to rest against the cylindrical surface of the rotating disk 343. At this time, the drum body 2 rotates clockwise, so that the drum body 2 drives the rotating disk 343 to rotate clockwise as well. The clockwise rotating rotating disk 343 can drive the friction block 344 to move leftward through friction, and the friction block 344 moves downward while moving leftward, so that the friction force between the friction block 344 and the rotating disk 343 is weakened, thereby preventing the friction block 344 from hindering the rotation of the clockwise unwinding drum body 2.

[0048] When the gantry moves toward the midpoint of its stroke, the cable is in a relaxed state, and the buffer spring pushes the movable frame 31 downward by its own elastic force, so that the push spring returns to its original state of natural extension, so that the friction block 344 does not contact the rotating disk 343, thereby allowing the reel body 2 to rotate counterclockwise and reel smoothly.

[0049] When the drum body 2 winds up the cable, the cable drives the guide tube 324 to rotate, so that the guide tube 324 on the left side moves back and forth along the axial direction of the reciprocating screw 321, and the guide tube 324 on the left side drives the guide tube 324 on the right side to move synchronously through the movable plate 331, so that when the drum body 2 is wound, the cable can be wound on the drum body 2 layer by layer to prevent the cables from being entangled with each other, thereby ensuring the smoothness of the cable when unwinding, and avoiding excessive pulling on the cable.

[0050] See also Figure 1 , Figure 2 and Figure 8 The reversing mechanism 4 includes a sliding member 41 which is slidably arranged at the front part of the plate-like structure on the front side of the mounting frame 1. The upper part of the sliding member 41 is an arc-shaped structure. An arc block 42 is slidably arranged at the upper part of the sliding member 41 along the track of its arc structure. Coil springs are arranged between the left and right sides of the arc block 42 and the sliding member 41. A follower disk 44 which rotates synchronously with the reel body 2 is fixedly installed at the front side of the reel body 2. The reversing mechanism 4 also includes a lifting component 43 for lifting the sliding member 41.

[0051] See also Figure 1 and Figure 2 The lifting assembly 43 includes a roller 431 rotatably arranged at the lower part of the sliding member 41 , and the lifting assembly 43 also includes an isosceles trapezoidal block 432 fixedly arranged in the middle of the gantry stroke and corresponding to the position of the roller 431 .

[0052] See also Figure 2 and Figure 8 A plurality of fan-shaped grooves 441 are formed at equal intervals along the circumference of the follower plate 44 , and a triangular block 442 for inserting into the fan-shaped groove 441 is fixedly mounted on the upper part of the arc block 42 .

[0053] When the gantry moves to the midpoint of its stroke, the mounting frame 1 drives the roller 431 to move to the position of the isosceles trapezoidal block 432 through the sliding member 41, so that the roller 431 moves to the upper part of the isosceles trapezoidal block 432 along the inclined surface, thereby causing the isosceles trapezoidal block 432 to push the sliding member 41 upwards, and the sliding member 41 drives the triangular block 442 through the arc block 42 to be inserted into the fan-shaped groove 441 at the corresponding position of the follower plate 44, so that the follower plate 44 drives the arc block 42 to rotate synchronously.

[0054] When the gantry moves to the midpoint of its stroke, the drum body 2 completely reels the cable, and the drum body 2 continues to rotate counterclockwise under the action of inertia, so that the drum body 2 drives the arc block 42 to slide to the right along the arc structure trajectory on the upper part of the sliding member 41 through the follower plate 44, and at the same time compresses the spiral spring on the right side. The gradually increasing elastic force of the spiral spring on the right side decelerates and stops the follower plate 44, preventing the counterclockwise rotating drum body 2 from pulling the cable.

[0055] The pointed structure on the upper part of the triangular block 442 can be easily inserted into the interior of the fan-shaped groove 441, so that the follower plate 44 pushes the arc block 42 to move, thereby stably compressing the coil spring.

[0056] Subsequently, the right-side coil spring pushes the follower plate 44 to rotate clockwise through its own elastic force, so that the follower plate 44 drives the drum body 2 to pre-start unwinding. When the gantry moves to the midpoint of its stroke without stopping but continues to move horizontally, the pre-start unwinding can make the drum body 2 rotate clockwise in advance, avoiding the cable from suddenly pulling the stationary or counterclockwise rotating drum body 2 to rotate clockwise, thereby avoiding pulling the cable.

[0057] See also Figure 1-Figure 8 When the cable and the gantry are moved synchronously, the present invention also includes the following steps: the first step is to connect the electrical equipment and the power supply equipment together by passing the cable through the drum body 2, and manually rotate the No. 1 screw 3222 to drive the two guide tubes 324 to clamp and limit the cable to the left and right.

[0058] In the second step, the second screw rod 334 is manually rotated so that the second screw rod 334 drives the two movable plates 331 to approach each other, so that the movable plate 331 drives the conical sleeve 333 to press against the outer surface of the cable through the follower 332, and then the conical sleeve 333 clamps the cable front and back to limit the position, preventing the cable from losing contact with the guide tube 324.

[0059] In the third step, the gantry moves away from the midpoint of its stroke, and the cable pulls the drum body 2 to rotate clockwise. When the gantry stops, the drum body 2 continues to rotate under the action of inertia, thereby releasing excess cable, and then the drum body 2 begins to rotate counterclockwise and reel in due to its own elastic force.

[0060] In the fourth step, the straightened cable drives the movable frame 31 to move upward, so that the movable frame 31 compresses the buffer spring and gradually increases the elastic force of the buffer spring, thereby buffering the cable straightening force. At the same time, the friction block 344 slows down the rotation of the rotating disk 343 to prevent the reel body 2 from pulling the cable due to rapid winding, thereby further preventing cable damage.

[0061] In the fifth step, the gantry moves toward the midpoint of its stroke, and the cable drives the guide tube 324 to rotate, so that the guide tube 324 on the left side reciprocates along the axial direction of the reciprocating screw 321. The cable can be wound on the drum body 2 layer by layer to prevent the cables from being entangled with each other, thereby ensuring the smoothness of the cable unwinding and avoiding excessive pulling on the cable.

[0062] Step 6. When the gantry moves to the midpoint of its stroke, the isosceles trapezoidal block 432 pushes the sliding member 41 upward, so that the follower disk 44 compresses the spiral spring on the right side through the arc block 42. The gradually increasing elastic force of the spiral spring on the right side decelerates and stops the follower disk 44, preventing the counterclockwise rotating drum body 2 from pulling the cable.

[0063] In the seventh step, when the gantry moves to the midpoint of its stroke, it does not stop but continues to move horizontally. Then, the right spiral spring pushes the follower plate 44 to rotate clockwise by its own elastic force. The follower plate 44 drives the drum body 2 to pre-rotate clockwise to prevent the cable from suddenly pulling the stationary or counterclockwise rotating drum body 2 to rotate clockwise, thereby avoiding pulling the cable.

[0064] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
