Description

Technical Field

[0001] The utility model belongs to the technical field of communication cable laying-out, and in particular relates to a communication cable laying-out device. Background Art

[0002] Communication cables are essential communication equipment used in power communication infrastructure. Specifically, in the process of communication infrastructure construction, communication cables are installed to connect unconnected communication base stations. Therefore, as the coverage of communication infrastructure increases, the coverage of communication cables also increases.

[0003] In the construction of communication cable infrastructure, the rolled cables need to be continuously unwound from the coil during the construction process. Specifically, during the construction process, the cables are unwound while being pulled. During the unwinding process, since the coils are often large in diameter and the number of turns of the wound cables is large, especially for thicker cables, the weight of the entire cable roll is very large, making it difficult to unwind.

[0004] At present, during construction, operators roll the cable through the steel pipe, mount it on the bracket, and rotate the cable roll to unwind it. However, the above method is only applicable to regular-sized cable rolls. For large and thick cables, such as optical cables, the bulky rolls cannot be rotated at all. Therefore, during the construction process, multiple workers drag the cables, but dragging large-caliber cables is not only laborious, but also requires the cooperation of multiple operators.

[0005] Therefore, in the actual construction process, motors are used to unwind the cables. However, the cables are too heavy and the construction range is wide. Traditional high-horsepower motors are large and heavy and cannot be carried at all. Low-horsepower motors cannot drive the heavy cables to unwind. As a result, how to unwind cables labor-savingly, especially heavy large-diameter cables, has always been a technical bottleneck in cable construction and has not been solved for a long time. Utility Model Content

[0006] Based on the above background, the purpose of the utility model is to provide a communication cable pay-out device.

[0007] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0008] A communication cable pay-off device, comprising a lower pay-off chassis mechanism and an upper loading rack mechanism rolling on the lower pay-off chassis mechanism;

[0009] The lower pay-off chassis mechanism comprises a chassis, and a plurality of rollers distributed in an annular manner are assembled and connected to the top edge of the chassis;

[0010] The upper material carrier mechanism comprises a material carrier, the bottom of which is supported on the top of the roller;

[0011] The communication cable pay-off device also includes a plurality of motor assemblies for driving the roller to rotate;

[0012] The material carrier comprises an annular frame portion, the annular frame portion is concentrically provided with a center seat, and a plurality of upper connecting beams are fixedly connected between the annular frame portion and the center seat;

[0013] The upper connecting beams are all provided with long assembly recesses, in which long assembly recesses are rotatably connected long roller rods; the cable coils are supported on the tops of the long roller rods.

[0014] Preferably, the roller comprises a roller frame, and a roller is rotatably connected in the roller frame;

[0015] The annular frame portion is supported on the top of the roller.

[0016] Preferably, the motor assembly comprises a motor, and an output shaft of the motor is fixedly assembled on the roller via a connecting piece.

[0017] Preferably, the motor assembly further comprises a motor bottom mounting frame, and the motor bottom mounting frame is fixedly mounted on the base frame.

[0018] Preferably, the base frame comprises an annular outer frame, the annular outer frame is concentrically provided with a central base, and the inner side wall of the annular outer frame is welded to the outer side wall of the central base through a plurality of lower connecting beams.

[0019] Preferably, a rotating shaft is fixedly connected to the bottom center position of the central seat, and the rotating shaft is rotatably connected to the top center position of the central base.

[0020] Preferably, the inner and outer ends of the long roller rod are respectively fixedly connected with an outer shaft rod and an inner shaft rod rotatably connected to the upper connecting beam;

[0021] The annular frame portion is threadedly connected with a locking bolt for locking the outer shaft rod.

[0022] Preferably, a material pressing mechanism for pressing the cable coil is fixedly connected to the top center of the center seat.

[0023] Preferably, the material pressing mechanism comprises a long shaft rod fixedly connected to the center seat;

[0024] A pressing ring is threadedly connected on the long shaft rod;

[0025] The pressing ring is coaxially provided with a threaded pipe seat which is threadedly connected to the long shaft rod.

[0026] The utility model has the following beneficial effects:

[0027] 1. In the process of unwinding the bulky cable coil, multiple motors work synchronously, each motor drives the roller, and the roller gives friction power to the carrier. With the cooperation of multiple motors, the carrier with the bulky cable coil on the load is driven to rotate. Then the unwinding is realized in a labor-saving way. Since there are multiple motors and small-sized and low-horsepower motors can be selected, it is convenient to carry and install. In this way, the bulky cable can be unwound in a stable and labor-saving way.

[0028] 2. During the working process, when the crane supports the cable roll on the loading rack, the cable roll is supported on the long roller rod. Due to the low accuracy of the crane unloading, it is often found that the center of gravity of the cable roll is too seriously eccentric with the center of the circle of the loading rack. The above-mentioned long roller rod design is used to realize that once the unloading roll is too seriously eccentric, multiple operators use tools such as crowbars to pry the cable roll rack (the cable roll is on the roll rack). In the process of prying the roll, the cable roll rotates and moves beyond the center position, and the heavy roll is supported on the long roller rod that can roll, so the resistance during the rotation is relatively small. In this way, the rotation and movement can be achieved until the center of gravity of the roll is almost coincident with the center of the loading rack, thereby achieving low unwinding resistance and high safety of unwinding.

[0039] Example 1

[0040] like Figure 1-5 As shown, a communication cable pay-off device comprises a lower pay-off chassis mechanism and an upper loading rack mechanism rolling on the lower pay-off chassis mechanism.

[0041] Specifically, the lower pay-off frame mechanism includes a frame, specifically to improve the load capacity of the frame, the frame includes an annular outer frame 1, the annular outer frame 1 is concentrically provided with a central base 11, the inner side wall of the annular outer frame 1 is welded to the outer side wall of the central base 11 through a plurality of lower connecting beams 12.

[0042] Similarly, the upper loading rack mechanism includes a loading rack 2, which includes an annular frame portion, on which a center seat 22 is concentrically arranged (a rotating shaft 22 is fixedly connected to the bottom center position of the center seat 22, and the rotating shaft 22 is rotatably connected to the top center position of the center base 11, and the specific method is to adopt an existing rotating connection method, such as installing an upper bearing seat at the top center of the center base 11, and the rotating shaft 22 is rotatably connected to the bearing seat), and a plurality of upper connecting beams 21 are fixedly connected between the annular frame portion and the center seat 22.

[0043] The coil passes under the crane until it is supported on the carrier 2.

[0044] During the construction, in order to facilitate the synchronous rotation of the material carrier 2-cable coil and unwind the cable, so as to realize the unwinding of the cable in a labor-saving, efficient and fast manner, the top edge of the above-mentioned base frame is equipped with a plurality of annularly distributed rollers 51 (the rollers 51 are rotatably connected to the roller 51 frame, the roller 51 frame is welded to the top of the annular outer frame 1, and the rollers 51 are distributed in an annular array); the bottom of the material carrier 2 (annular frame portion) is supported on the top of the rollers 51.

[0045] In this way, during the rotation process, the rolling friction of the roller 51 is used to realize flexible rotation unwinding. In addition, the carrier 2 is supported on a plurality of rollers 51 distributed in an annular manner, so the unwinding has high stability.

[0046] In the actual unwinding process, since the coil is too heavy, manual rotation of the coil is not only laborious but also inefficient. Therefore, the communication cable unwinding device further includes a plurality of motor components for driving the roller 51 to rotate.

[0047] Specifically, there are 10 rollers 51 and 5 motor assemblies, that is, one motor assembly is installed on two adjacent rollers 51, and the arrangement is roller 51-roller 51 / motor assembly... This method aims to drive the bulky coil through the cooperation of multiple motors.

[0048] Specifically, the motor assembly includes a motor 4, and the output shaft of the motor 4 is fixedly assembled on the roller 51 through a connecting piece. The axle on the roller 51 is rotatably connected to the roller 51 frame. According to the existing method, if a bearing is installed on the roller 51 frame, the bearing rotation connection method is more flexible. The outer end of the axle is installed on the output shaft of the motor 4 through a connecting flange 42.

[0049] During operation, the motors 4 work synchronously, each motor 4 drives the roller 51, and the roller 51 provides friction power to the carrier 2. With the cooperation of multiple motors 4, the carrier 2 loaded with heavy cable rolls is driven to rotate, thereby realizing unwinding in a labor-saving manner.

[0050] Since there are multiple motors 4 and the motors 4 with small size and small horsepower can be selected, it is convenient to carry and install.

[0051] Specifically, the motor assembly also includes a motor bottom mounting frame 41 (the motor 4 is fastened to the motor bottom mounting frame 41 by bolts, for example), and the motor bottom mounting frame 41 is fixedly assembled on the chassis. The motor 4 is pre-installed on the mounting frame during construction, and the motor 4 can be disassembled after construction.

[0052] Example 2

[0053] like Figure 1-5 As shown, based on the structure of Example 1, each of the upper connecting beams 21 is provided with a long assembly recess, in which a long roller rod 3 is rotatably connected; the cable coil is supported on the top of the long roller rod 3.

[0054] Specifically, the inner and outer ends of the long roller rod 3 are respectively fixedly connected with an outer shaft rod 31 and an inner shaft rod rotatably connected to the upper connecting beam 21 (specifically, according to the existing rotational connection method, the upper connecting beam 21 is provided with an adaptable shaft groove structure of the outer shaft rod 31 and the inner shaft rod, and the outer shaft rod 31 and the inner shaft rod are rotatably connected in the shaft groove).

[0055] During operation, when the crane supports the cable roll unwinding on the material carrier 2, the cable roll is supported on the long roller rod 3. Due to the low accuracy of the crane unwinding, it is often found that the cable roll is too seriously eccentric during actual operation, which is reflected in that one side is too close to the edge of the material carrier 2 and the other side is too far away from the material carrier 2. The serious eccentricity leads to low rotation stability during unwinding, and also causes different loads on the drive of the motor 4. In severe cases, the motor 4 with excessive load directly burns out. At the same time, the speed is not stable enough during unwinding.

[0056] The above-mentioned long roller rod 3 is designed to realize that once the unwinding coil is too eccentric, multiple operators use tools such as crowbars to pry the cable coil rack (the cable coil is on the coil rack). During the prying process, the cable coil rotates and moves beyond the center position, and the heavy coil is supported on the long roller rod 3 that can roll, so the resistance during the rotation is relatively small. In this way, the rotation is achieved until the center of gravity of the coil is almost coincident with the center of the carrier 2, thereby achieving low unwinding resistance and high safety of unwinding.

[0057] After the adjustment, in order to prevent the coil from slipping, the annular frame is threadedly connected with a locking bolt 311 for locking the outer shaft rod 31. The locking bolt 311 is screwed downward into the shaft groove where the outer shaft rod 31 is located, and squeezes and positions the outer shaft rod 31. Positioning is achieved to prevent the long roller rod 3 from rolling during the unwinding process.

[0058] Example 3

[0059] like Figure 1-5 As shown, based on the structure of Example 1, a material pressing mechanism for pressing the cable coil is fixedly connected to the top center of the center seat 22. After the cable is unwound and the posture is corrected in the above manner, it can be unwound. During the unwinding process, the stability and installation performance are increased by pressing the top of the coil.

[0060] Specifically, when unwinding a heavy coil, the center of gravity of the coil is not easy to coincide with the center of the circle of the carrier 2 when the coil is hoisted and unloaded onto the carrier 2. Although it is corrected, once the center of gravity is located, it is easy to rotate eccentrically during the unwinding process, and the heavy coil is easy to tip over. Therefore, the top of the coil is pressed by the pressing mechanism, and the coil is pressed between the carrier 2 and the pressing mechanism, so that even if the center of gravity is unstable, the coil is not easy to tip over.

[0061] Specifically, the pressing mechanism includes a long shaft rod 7 fixedly connected to the center seat 22; a pressing ring 61 is threadedly connected to the long shaft rod 7; and the pressing ring 61 is concentrically provided with a threaded pipe seat 62 threadedly connected to the long shaft rod 7 (a plurality of beams are welded to the pressing mechanism, and the beams are welded to the pressing ring 61). When the pressing ring 61 is rotated, the threaded pipe seat 62 slides down along the long shaft rod 7 and reaches the position of the coiling stand where the pressing ring 61 presses the cable coil.

[0062] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
