Abstract
Description
Technical Field
[0001] The invention relates to the field of safety protection equipment for electric power facilities, and in particular to a safety backup rope device for hanging bare poles of newly built electric power lines. Background Art
[0002] When electric power construction units build new power lines, they will install many electric poles.
[0003] As the name suggests, electric poles are poles for electric wires. They appear in various rural areas, fields, roads, and streets, and are one of the important infrastructures in early China. Various electric poles in the early days all started from wooden poles, even including high-voltage poles with not too high voltage levels.
[0004] In the early days, all kinds of electric poles started from wooden poles, even including high-voltage poles with not too high voltage levels. Later, due to the development of steel bars and concrete, combined with technical exploration, the principle of centrifugal force was used to manufacture reinforced concrete tapered cement poles and equal-diameter cement poles to replace most wooden poles. Cement poles are durable, corrosion-resistant, temperature-resistant, high-strength, and crack-resistant. In addition, suitable wood is gradually scarce, and cement poles have a smooth and beautiful appearance, which is more convenient for urban beautification. It is basically difficult to see wooden poles in the city. However, wooden poles are still used to set up telephone lines in some less developed areas because wooden poles are light in weight and easy to set up, and the load-bearing and tension of telephone lines are small, so wooden poles can do the job. If the telephone lines are changed, it is also convenient to move the poles. Therefore, there are still some wooden telephone poles.
[0005] Since the newly installed electric pole is just a smooth bare pole, workers are required to carry out various subsequent operations on the bare trunk. At this time, the workers can only use pole climbers (also known as foot hooks) to climb up the pole. However, since the bare pole of this power line is smooth overall, it is impossible to hang a backup rope, which means that the workers cannot get better protection and are prone to work-related accidents. Summary of the invention
[0006] The technical problem to be solved by the present invention is to provide a device for hanging a safety backup rope on a bare pole of a newly built power line, which can enable operators to hang a safety backup rope on the bare pole of the power line.
[0007] In order to solve the above technical problems, the technical solution of the present invention is: a device for hanging a safety backup rope on a bare pole of a newly built power line, comprising a locking device and an elastic ring belt, the locking device is arranged at one end of the ring belt, and teeth are arranged on the two side edges of the other end of the ring belt, the locking device comprises a sleeve and a hand-tightening nut matching the teeth, the inner diameter of the sleeve is larger than the width of the end of the ring belt where the teeth are arranged, the hand-tightening nut is rotatably connected to the sleeve and the axes of the two coincide, and a buckle for hanging a safety backup rope is fixedly connected to the ring belt.
[0008] Further: a rubber plate is arranged on the inner side of the ring belt.
[0009] Furthermore: the number of the rubber plates is more than 4, and they are arranged at intervals along the length direction of the endless belt.
[0010] Further: the ring belt includes a hoop plate and a plug plate, one end of the plug plate is provided with teeth and the other end thereof is rotatably connected with one end of the hoop plate and the rotation axis is perpendicular to the length direction of the ring belt, and the other end of the hoop plate is fixedly connected to the sleeve.
[0011] Further: the length ratio of the hoop plate to the plug plate is 1:1.2.
[0012] Further: the hand-tightened nut is arranged at one end of the sleeve, and the other end of the sleeve is fixedly connected to the hoop plate.
[0013] Furthermore: the ratio of the inner diameter of the sleeve to the width of the end of the ring belt provided with teeth is 1.05 times.
[0014] Further: one end of the sleeve is provided with a necking section rotatably connected to the hand nut, a baffle is provided at the end of the necking section, and a straight groove for passing the plug plate is provided along the axial direction of the necking section.
[0015] Further: the sleeve includes an outer sleeve and an inner sleeve, the inner diameter of the outer sleeve is slightly larger than the outer diameter of the inner sleeve, the outer sleeve and the inner sleeve are slidably connected along their axes, and a fixing device is provided between the outer sleeve and the inner sleeve to fix their relative positions.
[0016] Further: the fixing device comprises an adjustment hole arranged on the side wall of the outer sliding sleeve and a telescopic pin arranged on the side wall of the inner sliding sleeve, and the axis of the telescopic pin is perpendicular to the outer side surface of the plug plate.
[0017] By adopting the above technical solution, the beneficial effects of the present invention are as follows:
[0018] 1. The inventor of the present invention has keenly discovered the potential safety hazard of construction on bare poles of newly built power lines in existing power construction. In the past, workers could only use pole climbers (foot hooks) to fix on bare poles of newly built power lines. However, during actual construction work, workers would unconsciously shake their bodies, which would cause their legs to subconsciously adjust their center of gravity, thereby causing the foot hooks to move and causing a potential safety hazard of unstable gripping force. The present invention allows workers to set a reliable hanging point for a safety backup rope on the bare poles of newly built power lines after climbing to the working height, thereby avoiding the risk of accidental falls during construction.
[0019] 2. The present invention provides a locking device and an elastic ring belt, the locking device is provided at one end of the ring belt, and teeth are provided on the two side edges of the other end of the ring belt, and the locking device includes a sleeve and a hand nut matched with the teeth, the inner diameter of the sleeve is larger than the width of the end of the ring belt provided with teeth, the hand nut is rotatably connected to the sleeve and the axes of the two coincide, so that the operating personnel can manually put the ring belt on the bare pole of the newly built power line, and then the ring belt can be firmly locked on the bare pole of the newly built power line only by hand, and the operation does not require practical special tools, is simple and fast, safe and reliable, and is very convenient to disassemble and assemble.
[0020] 3. The present invention adopts the technical solution of arranging a rubber plate on the inner side of the annular belt, so that the device of the present invention can be more firmly fixed on the smooth bare pole of the newly built power line through the rubber plate which increases the friction.
[0021] 4. The present invention adopts the technical solution that the number of the rubber plates is more than 4 and they are arranged at intervals along the length direction of the endless belt, so that the device of the present invention will not have the phenomenon of the rubber plates being easily delaminated or even separated from the endless belt due to the different turning radius between the rubber plates and the endless belt and after long-term use, especially after long-term and frequent changes in locking diameters, thereby improving the reliability of the device and ensuring the safety of personnel operations.
[0022] 5. The present invention adopts a technical scheme that the ring belt includes a hoop plate and a plug plate, one end of the plug plate is provided with teeth and the other end thereof is rotatably connected with one end of the hoop plate, and the rotation axis is perpendicular to the length direction of the ring belt, and the other end of the hoop plate is fixedly connected with the sleeve, so that the ring belt of the device of the present invention is divided into two openable and closable sections. Because the ring belt should usually be made of elastic metal sheets, which are not easy to bend on the one hand, and prone to fatigue fracture after repeated large-scale bending on the other hand, thus creating a safety hazard. Therefore, after the ring belt is divided into two openable and closable sections, the ring belt can be opened to a large extent to hoop the bare pole of the newly built power line with a larger diameter, and then the ring belt can be conveniently closed for locking operation, thereby improving the installation efficiency and avoiding the safety hazard of repeated large-scale opening and closing.
[0023] 6. The present invention adopts a technical solution that the length ratio of the hoop plate and the plug plate is set to 1:1.2, so that the opening and closing range of the device of the present invention is maximized. Under normal conditions, the annular belt is divided into two equal-length belt plates to maximize the opening and closing range, thereby adapting to newly built power line bare poles of different diameters. However, because the plug plate also has a length for inserting the locking device, after repeated design and research, when the length ratio of the hoop plate and the plug plate is set to 1:1.2, it is guaranteed that there is a sufficient opening and closing range, and that the plug plate has a sufficient adjustment margin.
[0024] 7. The present invention adopts a technical solution in which the hand nut is arranged at one end of the sleeve and the other end of the sleeve is fixedly connected to the hoop plate, so that the hand nut of the device of the present invention is as far away from the ring band as possible after the ring band is closed, so that the operator can tighten and loosen the hand nut more conveniently, which not only improves the operation time of installing the device, but most importantly ensures sufficient hand tightening force and ensures the firmness of the locking.
[0025] 8. The present invention adopts a technical solution that the ratio of the inner diameter of the sleeve to the width of the end of the ring belt provided with teeth is 1.05 times, so that the plugboard of the device of the present invention is relatively less likely to shake after being inserted into the sleeve. On the one hand, the sleeve with such an inner diameter ensures that the plugboard can be inserted therein quickly and conveniently. On the other hand, compared with a sleeve that is too loose, the inserted plugboard is more stable in the sleeve and will not shake significantly. In particular, after the ring belt is locked, the plugboard will inevitably tilt toward the inner circle. At this time, if the tilt is too large, the coordination force between the teeth and the hand nut will be unbalanced. Over time, the teeth and the hand nut will be excessively worn on one side, which on the one hand reduces the service life of the equipment, and on the other hand, the unbalanced force is also prone to cause safety hazards such as tooth cracking.
[0026] 9. The present invention provides a necking section rotatably connected to the hand nut at one end of the sleeve, a baffle is provided at the end of the necking section, and a slot for passing the insert plate is provided along the axial direction of the necking section, so that the structure of the device of the present invention is more compact and reasonable. This structure only needs to machine a necking section that can be inserted into the hand nut during the machining process. After the hand nut is inserted, a flaring tool is used to expand the necking section into a baffle that prevents the hand nut from falling off during assembly. In this way, the overall manufacturing process of the device is simple, the number of parts required to be manufactured is small, and the cost is low, the structure is compact and reasonable, the working reliability is high, it is conducive to wide promotion, and it has high economic and practical value.
[0027] 10. The present invention adopts a technical solution that the sleeve includes an outer sleeve and an inner sleeve, the inner diameter of the outer sleeve is slightly larger than the outer diameter of the inner sleeve, the outer sleeve and the inner sleeve are slidably connected along their axes, and a fixing device for fixing the relative positions of the outer sleeve and the inner sleeve is provided between the outer sleeve and the inner sleeve, so that the sleeve of the device of the present invention has an adjustment function. Because locking the plug plate by a hand nut is a relatively slow process, in order to increase the speed of the locking operation, the moving distance of the plug plate in the hand nut should be minimized. However, for newly built power line bare poles with different diameters, the moving distance of the plug plate in the hand nut does not have a fixed value. Therefore, the length of the sleeve is adjusted, so that for newly built power line bare poles with different diameters, the moving distance of the plug plate in the hand nut can be minimized by quickly adjusting the length of the sleeve.
[0028] 11. The present invention adopts a technical solution that the fixing device includes an adjustment hole arranged on the side wall of the outer sleeve and a telescopic pin arranged on the side wall of the inner sleeve, and the axis of the telescopic pin is perpendicular to the outer side surface of the plug plate, so that the structure of the device of the present invention is more compact. Because the plug plate is in an oblong shape, it has a large redundant space on the inner and outer sides relative to the internal space of the cylindrical sleeve, and this redundant space can be used to set a quickly adjustable fixing device such as a telescopic pin, ultimately making the structure of the device more compact and reasonable.

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to those of ordinary skill in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be considered as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so that once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.
[0039] In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the attached Figure 1 The orientation or position relationship formed by the coordinate system shown in the (i.e., main view), and when discussing views in other directions, the coordinate system will not rotate accordingly. The above-mentioned orientation terms are only for the convenience of describing this application and simplifying the description. In the absence of contrary or specific instructions, these orientation terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of this application; in addition, the orientation terms "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0041] It should also be noted that the use of words such as "first" and "second" to limit components is only to facilitate the distinction between corresponding components. If not otherwise stated, the above words have no special meanings, especially there are no specific meanings of "primary" or "secondary" or arrangement order, and therefore cannot be understood as limiting the scope of protection of this application.
[0042] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0043] like Figures 1 to 4 As shown, the structure of the present invention is generally in the shape of a circular ring, and its basic part includes a ring belt body and a locking device 16. The belt body is elastic and is generally recommended to be made of spring steel. The locking device 16 is arranged at one end of the ring belt, and teeth 8 are arranged on the two side edges of the other end of the ring belt. The locking device 16 includes a sleeve and a hand-tightening nut 10 matched with the teeth 8. The inner diameter of the sleeve is larger than the width of the end of the ring belt where the teeth 8 are arranged (because the ring belt has a thickness and a width, the width of the end of the ring belt where the teeth 8 are arranged is Figure 3 The maximum distance between the teeth 8 on both sides is shown in the figure), the hand-tightening nut 10 is rotatably connected to the sleeve and the axes of the two coincide, and a buckle 5 for hanging a safety backup rope is fixedly connected to the ring belt.
[0044] This arrangement allows operators to manually put the ring belt on the bare pole of the newly built power line, and then manually lock the ring belt firmly on the bare pole of the newly built power line. The operation does not require any special tools, and is simple, fast, safe and reliable, and is very convenient to disassemble and assemble.
[0045] In addition, since the buckle 5 for hanging the safety backup rope is fixedly connected to the ring belt, the working conditions that the workers could only use the pole climber (foot hook) to fix on the bare pole of the newly built power line in the past are improved. Because in actual construction work, the workers will unconsciously shake their bodies, which will drive their legs to adjust their center of gravity subconsciously, thereby driving the foot hook to move and causing a safety hazard of unstable gripping force. The present invention allows the workers to set a reliable hanging point for the safety backup rope on the bare pole of the newly built power line after climbing to the working height, thereby avoiding the risk of accidental falling of the workers during construction.
[0046] In addition, the present invention can further be provided with a rubber plate 2 on the inner side of the annular belt. This arrangement enables the device of the present invention to be more firmly fixed on the smooth newly-built power line bare pole by increasing the friction of the rubber plate 2.
[0047] In addition, Figure 1 As shown, the present invention can further set the number of the rubber plates 2 to be more than 4, and arrange them at intervals along the length direction of the endless belt.
[0048] This arrangement prevents the rubber sheet 2 from being easily delaminated or even separated from the endless belt due to the different turning radius between the rubber sheet 2 and the endless belt after long-term use, especially after long-term and frequent changes in locking diameters. This improves the reliability of the device and ensures the safety of personnel operations.
[0049] In addition, Figure 1 As shown, the present invention can further include the hoop plate 4 and the plug plate 1, one end of the plug plate 1 is provided with teeth 8 and the other end thereof is rotatably connected with one end of the hoop plate 4 and the rotation axis is perpendicular to the length direction of the hoop plate, and the other end of the hoop plate 4 is fixedly connected with the sleeve. Specifically, the hoop plate 4 and the plug plate 1 are connected by a rotating shaft 3.
[0050] This arrangement allows the ring belt of the device of the present invention to be divided into two openable and closable sections, because the ring belt should usually be made of elastic metal sheets, which are not easy to bend on the one hand, and are prone to fatigue fracture after repeated large-scale bending on the other hand, thereby creating a safety hazard. Therefore, after the ring belt is divided into two openable and closable sections, the ring belt can be opened to a large extent to clamp the bare pole of a newly built power line with a larger diameter, and then the ring belt can be conveniently closed for locking operations, thereby improving the installation efficiency and avoiding the safety hazard of repeated large-scale opening and closing.
[0051] In addition, the present invention can further make the length ratio of the hoop plate 4 and the plug plate 1 be 1:1.2.
[0052] This arrangement maximizes the opening and closing range of the device of the present invention. Under normal conditions, the annular belt is divided into two equal-length belt plates to maximize the opening and closing range, thereby adapting to newly built bare power line poles of different diameters. However, because the plug plate 1 also has a length for inserting the locking device, after repeated design and research, when the length ratio of the hoop plate 4 and the plug plate 1 is set to 1:1.2, it is guaranteed that the opening and closing range is sufficient, and the plug plate 1 has sufficient adjustment margin, and the structure is more reasonable.
[0053] In addition, Figure 1 As shown, the present invention can further enable the hand nut 10 to be arranged at one end of the sleeve, and the other end of the sleeve is fixedly connected to the hoop plate 4.
[0054] This arrangement ensures that the hand-tightening nut 10 of the device of the present invention is as far away from the annular band as possible after the annular band is closed, so that the operator can tighten and loosen the hand-tightening nut 10 more conveniently, which not only improves the operation time of installing the device, but most importantly ensures sufficient hand-tightening force and ensures the firmness of the locking.
[0055] In addition, the present invention can further set the inner diameter of the sleeve to 1.05 times the width of the end of the annular belt where the teeth 8 are provided.
[0056] This arrangement makes it relatively less likely for the plugboard 1 of the device of the present invention to shake after being inserted into the sleeve. On the one hand, the sleeve with such an inner diameter ensures that the plugboard 1 can be inserted therein quickly and conveniently. On the other hand, compared with a sleeve that is too loose, the plugboard 1 after insertion is more stable in the sleeve and will not shake significantly. In particular, after the annular band is locked, the plugboard 1 will inevitably tilt toward the inner circle. At this time, if the tilt is too large, the matching force between the teeth 8 and the hand nut 10 will be unbalanced. Over time, the teeth 8 and the hand nut 10 will be excessively worn on one side, which on the one hand reduces the service life of the equipment, and on the other hand, the unbalanced force is also prone to cause the safety hazard of the teeth 8 breaking.
[0057] In addition, Figures 2 to 4 As shown, the present invention can further provide one end of the sleeve with a necking section 11 rotatably connected to the hand nut 10, a baffle 9 is provided at the end of the necking section 11, and a straight groove 15 for passing the plug plate 1 is provided along the axial direction of the necking section 11.
[0058] Such an arrangement makes the structure of the device of the present invention more compact and reasonable. This structure only needs to machine a necked section 11 that can be inserted into the hand-tightening nut 10 during the machining process. After the hand-tightening nut 10 is inserted, a flaring tool is used to expand the necked section 11 into a baffle 9 that prevents the hand-tightening nut from falling off during the assembly operation. In this way, the overall manufacturing process of the device is simple, and the number of parts required to be manufactured is small. Therefore, the cost is low, the structure is compact and reasonable, the working reliability is high, it is conducive to wide promotion, and it has high economic and practical value.
[0059] In addition, Figures 2 to 4 As shown, the present invention can further make the sleeve include an outer sleeve 14 and an inner sleeve 12, the inner diameter of the outer sleeve 14 is slightly larger than the outer diameter of the inner sleeve 12, the outer sleeve 14 and the inner sleeve 12 are slidably connected along their axes, and a fixing device is provided between the outer sleeve 14 and the inner sleeve 12 to fix the relative positions of the two.
[0060] This arrangement enables the sleeve of the device of the present invention to have an adjustment function, because locking the plug plate 1 by the hand-tightening nut 10 is a relatively slow process, so in order to increase the speed of the locking operation, the moving distance of the plug plate 1 in the hand-tightening nut 10 should be minimized. However, for newly built power line bare poles with different diameters, the moving distance of the plug plate 1 in the hand-tightening nut 10 does not have a fixed value, so the length of the sleeve is adjusted, so that when dealing with newly built power line bare poles with different diameters, the moving distance of the plug plate 1 in the hand-tightening nut 10 can be minimized by quickly adjusting the length of the sleeve.
[0061] Finally Figure 2 As shown, the present invention can further make the fixing device include an adjustment hole 6 arranged on the side wall of the outer sliding sleeve 14 and a telescopic pin arranged on the side wall of the inner sliding sleeve 12, and the axis of the telescopic pin is perpendicular to the outer side surface of the plug board 1.
[0062] Specifically, the telescopic pin of this embodiment is a latch pin 7 disposed on the inner sleeve 12, the latch pin 7 passes through a corresponding hole on the inner sleeve 12, and a spring sheet 13 fixed to the inner wall of the inner sleeve 12 is disposed at the bottom of the latch pin 7, so that the latch pin 7 can be telescoped on the side wall surface of the inner sleeve 12, and the relative position of the outer sleeve 14 and the inner sleeve 12 can be adjusted and fixed by cooperating with the adjustment hole 6 having the same diameter as the latch pin 7. In addition, other fixing devices such as buckles can also be applied here.
[0063] Such an arrangement makes the structure of the device of the present invention more compact, because the plug plate 1 is in an oblong shape, and relative to the internal space of the cylindrical sleeve, it has a larger redundant space on the inner and outer sides, and this redundant space can be used to set a quickly adjustable fixing device such as a telescopic pin, ultimately making the structure of the device more compact and reasonable.
[0064] Finally, it is still necessary to emphasize that the embodiments described above are obviously only part of the embodiments of the present invention, not all of the embodiments, and the specific embodiments described here are only used to explain the present invention, and are not used to limit the claims of the present invention. Based on the embodiments of the present invention, any obvious changes made by ordinary technicians in this field under the design concept of the present invention are within the scope of protection of the present invention.
