Description

Technical Field

[0001] The present invention relates to a driving mechanism of a power optical cable bundling and laying machine, belonging to the technical field of power optical cable construction tools. Background Art

[0002] The driving mechanism of the existing power optical cable bundling and laying machine is found to have some defects during actual use. First, the fixed cover is fixed only at one point by a shaft rod without other fixed supports. In this way, the bundling and laying machine will become loose as long as it runs, and the fixed cover may fall off at any time and cannot work. Second, the shaft rod is fixedly installed on the base first, and then the driving wheel and the fixed cover are installed on the shaft rod. There are many and miscellaneous components, which increase the manufacturing process and cost. Third, both the output pulley and the deflection pulley are installed on the fixed cover, which is not only very troublesome and time-consuming to install, but also inconvenient for threading the binding wire, greatly affecting the work efficiency and operation mood. Fourth, the fixed cover is not provided with a wire blocking recess or a wire blocking coil, so that the binding wire often falls into the gap between the fixed cover and the driving wheel, resulting in the bundling and laying machine being unable to work, and repeated maintenance and treatment are time-consuming and laborious. Fifth, the driving wheel, the fixed cover, and the fixed cover support are of solid structures, with a heavy overall weight, which is very disadvantageous for high-altitude power operations. Sixth, the driving wheel has no traveling tires, resulting in large vibration and noise during the operation of the driving wheel and very poor reliability. It seriously affects the performance and use effect of the whole machine. Therefore, it is very necessary to develop a driving mechanism of a power optical cable bundling and laying machine suitable for high-altitude power optical fiber bundling operations. Summary of the Invention

[0003] The purpose of the present invention is to provide a driving mechanism of a power optical cable bundling and laying machine with fewer parts manufacturing processes, simple structure and assembly, light overall weight, flexible and convenient driving, smooth and reliable operation of the binding wire, basically no vibration and noise, and low cost, so as to be suitable for high-altitude power optical fiber bundling operations, aiming at the above-mentioned deficiencies of the existing technology.

[0004] The present invention realizes the above purpose through the following technical solutions:

[0005] A driving mechanism of a power optical cable bundling and laying machine, which includes a driving wheel, a fixed cover, a fixed shaft rod, a fixed cover support, a deflecting pulley, an output pulley, a rotating body, and a non-rotating wheel. It is characterized in that: the driving wheel is composed of a walking part, a winding part, and a walking tire. The upper end surface of the walking part is made with a winding part, and the walking part is integrally provided with a walking tire, and the walking tire is made of an elastic soft colloid; the walking tire is pasted or injection-molded into the rim of the walking part; the fixed cover is made with a fixed shaft rod hole; the walking part is movably connected with the non-rotating wheel through the elastic soft colloid of the walking tire to form a friction pair; the driving wheel is installed on the rotating body through the fixed cover and the fixed shaft rod via the fixed shaft rod hole, and the fixed cover is installed parallel to the end surface of the winding part through the fixed cover support; the fixed cover support is installed on the rotating body, an output pulley is installed on the right side of the fixed cover support, and a deflecting pulley is installed on the left side of the fixed cover support. The output pulley, the winding part, and the deflecting pulley form a transmission bundling wire pulley group, and the winding part is wound with a bundling wire to provide sufficient friction for the walking part.

[0006] The rim of the walking part is an inclined low rim, and the walking tire is pasted or injection-molded into the inclined low rim.

[0007] The walking tire is an inclined surface elastic soft colloid circle with one side of the diameter being larger and the other side being smaller, which is tightly fitted with the shape of the inclined low rim of the walking part to form a chamfer at the edge of the walking part, increasing the contact surface and friction between the driving wheel and the non-rotating wheel X.

[0008] The installation positions of the output pulley and the deflecting pulley are appropriately adjusted with the winding part as the reference to ensure the smooth running of the bundling wire and the proper tightness of the bundling.

[0009] The diameter of the walking part is larger than the diameter of the winding part.

[0010] The driving wheel, the fixed cover, and the fixed cover support are made into a hollow structure by 3D printing to reduce the weight of the whole machine.

[0011] A wire blocking recess or a wire blocking coil concentric with the fixed shaft rod hole is made inside the fixed cover.

[0012] Weight-reducing holes are made on the spoke plates of the driving wheel.

[0013] The bundling wire passes through the deflecting pulley, winds around the winding part, and passes through the output pulley in sequence. The driving wheel rotates by the traction of the bundling wire; when the winding direction of the bundling wire on the winding part is different, the rotating direction of the rotating body is also different.

[0014] The beneficial effects of the present invention compared with the prior art are as follows:

[0015] The driving mechanism of the power optical cable bundling and laying machine avoids the risk of loosening and falling off of components during the operation of the whole machine by using multi-point fixation for the fixed cover, making the driving wheel and its related components operate more stably and reliably. The fixed cover and the driving wheel are fixedly installed on the rotating body through a fixed shaft rod, effectively reducing the number of components and manufacturing processes, with a simple structure and greatly reducing costs. The output pulley and the deflecting pulley are reasonably arranged, and the distance between them is appropriately increased, enabling quick installation, less time consumption, convenient threading of the bundling wire, and high operation efficiency. The wire blocking recess or wire blocking coil made on the fixed cover corresponds to the winding part, completely avoiding the shutdown failure caused by the bundling wire falling into the gap between the fixed cover and the winding part, and making the operation of the whole machine smoother and more reliable. By opening weight-reducing holes on the driving wheel and simultaneously making the driving wheel, fixed cover, and fixed cover support into hollow structures, both the weight of the whole machine is reduced and the material usage is decreased, greatly reducing the load on power personnel when lifting and operating the whole machine and further reducing costs. The walking tires are designed to increase the friction and operation reliability of the walking part, greatly reducing the vibration and noise during the operation of the driving wheel. It solves the problems of the existing single-point fixation method where components are prone to loosening and falling off, being unsafe, the assembly structure being unscientific, having many components, increasing manufacturing processes and costs, the overall weight of the driving wheel being heavy, and there being no wire blocking and no walking tire setting, resulting in the whole machine being unable to work properly and smoothly, consuming a lot of time and labor for repeated repair and treatment, the overall weight being heavy, which is very unfavorable for high-altitude power operations, as well as the large vibration and noise and poor reliability during the operation of the driving wheel, seriously affecting the performance and use effect of the whole machine.

Specific implementation mode

[0027] The design idea of the applicant of the present invention is as follows: The power optical cable laying machine with the Chinese invention title of "A Construction Tool for Overhead Optical Cable Lines" and the Chinese patent number of 200910063697.6 is a product developed and patented by the applicant of the present invention. During the debugging, the following defects are found in its driving device: First, the fixed cover 4 and the shaft rod are fixed at only one point and there is no other fixed support. In this way, the machine will become loose as soon as it runs and may fall off at any time and cannot work. Second, the shaft rod is first fixed through the base and then the driving wheel and the fixed cover 4 are installed. This not only increases the manufacturing processes and the complexity of the components, but also greatly increases the cost. Third, the pulley position is not reasonably designed. The output pulley 7 and the deflecting pulley 9 are both installed on the fixed cover 4, which is not only very troublesome to install, time-consuming and laborious, but also brings great inconvenience to threading the binding wire 10, greatly affecting the work efficiency and the working mood. Fourth, since the fixed cover 4 is not provided with a wire blocking recess or a wire blocking coil 6, in actual work, the binding wire 10 often falls into the gap between the fixed cover 4 and the driving wheel, making the machine unable to work and requiring repeated maintenance and treatment, which is time-consuming and laborious. Fifth, the weight reduction hole 11 is not designed, and the driving wheel, the fixed cover 4 and the fixed cover support 8 are of solid structure, resulting in a very heavy overall weight of the machine, which is very unfavorable for the operation of lifting the machine at a long distance with an insulating rod. Sixth, the traveling tire 3 is not designed, resulting in a very small friction force of the driving wheel, poor reliability during operation, large vibration and large noise. Therefore, it is thought to develop an improved and optimized driving mechanism of a power optical cable binding and laying machine, which has a simple structure, saves time and effort, and is stable and reliable in work, so as to be suitable for the operation of binding optical fibers at high altitude in the power industry and meet the power construction requirements.

[0028] The following further details the implementation mode of the driving mechanism of the power optical cable binding and laying machine in conjunction with the attached drawings (see Figures 1 to 10 )

[0029] The driving mechanism of the power optical cable binding and laying machine includes a driving wheel, a fixed cover 4, a fixed shaft rod 5, a fixed cover support 8, a deflecting pulley 9, an output pulley 7, a rotating body 13, and a non-rotating wheel X. The driving wheel is composed of a walking part 1, a winding part 2, and a walking tire 3. The upper end surface of the walking part 1 is made with the winding part 2, and the walking part 1 is integrally provided with the walking tire 3. The walking tire 3 is made of an elastic soft colloid. The walking tire 3 is pasted or injection-molded into the rim of the walking part 1. The fixed cover 4 is made with a fixed shaft rod hole 12, and a wire blocking recess or a wire blocking coil 6 is made concentric with the fixed shaft rod hole 12. The walking part 1 is movably connected to the non-rotating wheel X through the elastic soft colloid of the walking tire 3 to form a friction pair. When driving, the non-rotating wheel X is pressed against, and when not driving, the non-rotating wheel X is separated. The driving wheel is installed on the rotating body 13 through the fixed cover 4 and the fixed shaft rod 5 via the fixed shaft rod hole 12. The fixed cover 4 is installed parallel to the end face of the winding part 2 through the fixed cover support 8. The fixed cover support 8 is installed on the rotating body 13. An output pulley 7 is installed on the right side of the fixed cover support 8, and a deflecting pulley 9 is installed on the left side of the fixed cover support 8. The output pulley 7, the winding part 2, and the deflecting pulley 9 form a pulley group for conveying the binding wire 10. The winding part 2 is wound with the binding wire 10 to provide sufficient friction for the walking part 1. The driving wheel, the fixed cover 4, and the fixed cover support 8 are of a hollow structure.

[0030] The fixed cover 4 and the driving wheel are installed and fixed on the rotating body 13 through the fixed shaft rod 5, the fixed shaft rod hole 12, and the fixed cover support 8, and the end face of the winding part 2 extends into the wire blocking recess or the wire blocking coil 6 of the fixed cover 4 and is parallel to the fixed cover 4. A bearing or a shaft sleeve or a bearing bush assembly form is adopted between the driving wheel and the fixed shaft rod 5. The assembly principle is that the driving wheel must be able to rotate flexibly.

[0031] The installation positions of the output pulley 7 and the change-direction pulley 9 are appropriately adjusted based on the winding part 2 to ensure that the binding wire 10 runs smoothly and the binding tightness is appropriate. The diameter of the walking part 1 is larger than the diameter of the winding part 2. The walking tire 3 is an elastic soft colloid circle with an inclined surface, that is, the diameter of the elastic soft colloid circle is large on one side and small on the other side, which is tightly matched with the inclined low rim of the walking part 1. The walking tire 3 is injection molded or pasted or embedded in the inclined low rim of the walking part 1. The diameter of the wheel edge of the inclined low rim of the walking part 1 is large on one side and small on the other side. To make the wheel edge of the walking part 1 chamfered, the elastic soft colloid of the walking tire 3 must be completely corresponding to the wheel edge shape of the inclined low rim of the walking part 1, firmly, tightly, matching, uniformly pasted or injection molded or embedded into one body, the purpose is to make the contact surface and friction between the driving wheel and the non-rotating wheel X larger, and at the same time the device can be made smaller, so as to effectively save assembly space and production costs. The driving wheel, the fixed cover 4 and the fixed cover support 8 are made into a hollow structure by 3D printing, which reduces the weight of the whole machine. The spoke plate of the driving wheel is made with a weight-reducing hole 11 to reduce the weight and facilitate handling. The binding wire 10 is sequentially inserted into the change-direction pulley 9, wound around the winding part 2, and passed through the output pulley 7, and the driving wheel is rotated by the traction of the binding wire 10.

[0032] During installation, the installation position of the fixed cover support 8 is close to the middle position of the rotating body 13, and one end of the fixed cover 4 is fixed on the rotating body 13 through the fixed cover support 8 in order to better install the driving wheel. An output pulley 7 is installed on the fixed cover 4 at the other end of the fixed cover support 8. The installation position of the output pulley 7 needs to take into account the winding part 2 and enable the binding line 10 to be smoothly routed and smoothly output. A walking tire 3 is injection molded or pasted in the rim of the walking part 1. The walking tire 3 is made of elastic soft colloid. The walking part 1 is designed as a special inclined low rim in order to obtain a better contact surface between the driving wheel and the non-rotating wheel X, thereby increasing the friction and the force-bearing surface. The walking tire 3 is not a conventional relationship between a tire, a wheel hub and a rim. The walking tire 3 made of elastic soft colloid is bonded or injection molded to the walking part 1 to form a whole, so as to increase the pressing surface and friction when the walking part 1 is walking, and reduce vibration and noise.

[0033] The direction-changing pulley 9 is installed on the rotating body 13 corresponding to the position of the winding part 2, and is opposite to the installation direction of the output pulley 7. The direction-changing pulley 9, the winding part 2 and the output pulley 7 are three pulleys that constitute the transmission binding line 10, forming a pulley block. The two pulleys composed of the winding part 2 and the walking part 1 need to carry the load through the walking part 1, so in actual use, the binding line 10 must be wound around the winding part 2 at least one or several times to ensure sufficient friction. And in actual use, the installation position of the output pulley 7 and the direction-changing pulley 9 should be appropriately adjusted based on the assembly position of the winding part 2, so that the binding line 10 can be routed smoothly and the binding tightness is appropriate.

[0034] The reasonable and coordinated assembly of all components of the driving mechanism of this power optical cable bundling and laying machine is the key to ensuring the good working performance of the whole machine. During live working, the staff need to use an insulating rod to remotely extend and operate the optical cable bundling and laying machine. This requires that the weight of the whole machine of the optical cable bundling and laying machine be as light as possible on the premise of ensuring the working performance. In the research and development of the present invention, the applicant uses 3D printing technology to manufacture the driving wheel, fixed cover 4 and fixed cover support 8, and makes their internal parts into a hollow mesh structure, which greatly reduces the weight of the whole machine. At the same time, a number of weight-reducing holes 11 are opened on the web of the driving wheel, which further reduces the weight of the components and is also convenient for grasping. The driving wheel, fixed cover 4 and fixed cover support 8 can also be designed to be injection-molded once with a hollow mesh structure inside.

[0035] The binding wire 10 passes through the deflecting pulley 9 in sequence, then winds around the winding part 2 and then passes through the output pulley 7 to fix the wire end on the binding object. As long as the binding wire 10 is subjected to a certain traction force, the deflecting pulley 9, the winding part 2 and the output pulley 7, and the winding part 2 and the traveling part 1 will rotate smoothly. The rotation of the driving wheel is used for the traveling tire 3 of the traveling part 1 to do work by traveling, so that the rotating body 13 and all the components on it rotate simultaneously. When the direction of the binding wire 10 wound around the winding part 2 is different, the rotation direction of the rotating body 13 is also different.

[0036] The functions of the components in the driving mechanism of this power optical cable bundling and laying machine are as follows:

[0037] The function of the traveling part 1 is: to make the driving wheel travel on the non-rotating wheel X according to the designed track.

[0038] The function of the winding part 2 is: to wind the binding wire 10 and generate a rotating force through the binding wire 10.

[0039] The function of the traveling tire 3 is: to increase the traveling friction and reduce the vibration and noise during traveling.

[0040] The function of the fixed cover 4 is: to fixedly install the driving wheel through the fixed shaft rod 5 and the fixed shaft rod hole 12.

[0041] The function of the fixed shaft rod 5 is: to fixedly install the fixed cover 4 and the driving wheel on the rotating body 13.

[0042] The function of the wire blocking recess or wire blocking coil 6 is: to prevent the binding wire 10 from falling into the gap between the winding part 2 and the fixed cover 4.

[0043] The function of the output pulley 7 is: to determine the corresponding position of the binding wire 10 and the winding part 2 and output the binding wire 10.

[0044] The function of the fixed cover support 8 is: to fix the fixed cover 4 parallel to the end face of the winding part 2.

[0045] The function of the deflecting pulley 9 is to change the routing direction of the binding wire 10 and straighten the corresponding winding part 2 of the binding wire 10.

[0046] The function of the binding wire 10 is to drive the running part 1 to rotate under load through the winding part 2 and bind the optical cable at the same time.

[0047] The function of the weight reduction hole 11 is to reduce the weight of the driving wheel.

[0048] The function of the fixed shaft rod hole 12 is to allow the fixed shaft rod 5 to pass through.

[0049] The function of the rotating body 13 is to install and fix the driving wheel through the fixed cover 4, the fixed shaft rod 5 and the fixed cover support 8, and install the deflecting pulley 9 at the same time.

[0050] The function of the non-rotating wheel X is to make the driving wheel walk close to the inclined low rim edge of the running part 1 through the running tire 3, generating a force to drive the rotating body 13 to rotate. The non-rotating wheel X only moves and never rotates.

[0051] The above are only the preferred embodiments of the present invention. The above examples do not impose any formal restrictions on the essence of the present invention. Any simple modification or deformation made by those of ordinary skill in the art to the above specific embodiments according to the technical essence of the present invention after reading this specification, and any equivalent embodiments that may be changed or modified by using the above-disclosed technical content into equivalent variations still fall within the scope of the technical solution of the present invention without departing from the essence and scope of the present invention.
