Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of power facility technology, and more specifically, to a guy wire sheath for power operations. Background Technology

[0002] In the field of power operations, guy wires are a key component for ensuring the balance of force on power poles, and their safety is of paramount importance. Guy wires are usually made of multi-strand steel strands. In practical applications, once the guy wire is damaged, it is very easy to cause uneven stress on the power pole, and in severe cases, it may even threaten the safe operation of the entire transmission line. In addition, the exposed guy wires have a relatively small surface area, making them difficult to attract people's attention visually, which increases the risk of pedestrians or vehicles colliding with them. The stubble at the end of the guy wire may also cause accidental injury to passing pedestrians.

[0003] To effectively address these issues, warning sleeves are typically added to exposed guy wires in practical operations. Traditional guy wire sleeves are generally just a simple tube fitted over the guy wire. Common structures include a thicker sleeve fitted over the lower section of the guy wire and a thinner sleeve fitted over the upper section of the guy wire. Warning strips are affixed or coated on the outside of the tube to enhance the warning effect. While this traditional design is simple and inexpensive, it was widely adopted in the past. However, with the increasing demands of power operations, its drawbacks have become increasingly apparent. On the one hand, there is a lack of reliable limiting and relative fixing measures between the tube and the guy wire. Under the influence of wind or other external forces, the sleeve can easily move up and down along the guy wire, thus failing to fulfill its intended warning function. On the other hand, traditional sleeves are mostly two-piece structures, requiring numerous connectors during installation, making the process cumbersome, and resulting in poor stability after installation, leading to a shorter service life.

[0004] With the rapid development of the power and telecommunications industry, the presence of a large number of guy wires on power poles has caused considerable inconvenience to pedestrians and vehicles in urban and rural areas, resulting in frequent accidents involving vehicle damage and fatalities. This not only poses a serious threat to the safety of public life and property but also has a negative impact on the stable operation of power facilities. Against this backdrop, it is urgent to develop a new type of guy wire sheath for power operations that can overcome the defects of traditional guy wire sheaths, has more efficient wire delivery and precise limiting functions, and is easy to install, stable, and durable. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a guy wire sheath for power work, which solves the problem that the shortcomings of the prior art have gradually become apparent as the requirements of power work continue to increase. On the one hand, there is a lack of reliable limiting and relative fixing measures between the pipe body and the guy wire. Under the action of wind or other external forces, the sheath is easy to move up and down along the guy wire, thus failing to play its due warning role. On the other hand, traditional sheaths are mostly two-body structures, which not only require the use of more connectors during installation, making the operation process cumbersome, but also have poor stability after installation, resulting in a short service life.

[0006] According to one aspect, at least one embodiment of this disclosure provides a guy wire sheath for power work, comprising:

[0007] A processing table, wherein a pull wire sleeve is provided on the upper end surface of the processing table;

[0008] A drive wire feeding assembly is mounted on the processing table;

[0009] An auxiliary limiting component is disposed on the upper surface of the processing table;

[0010] The drive wire feeding assembly includes a support frame with a drive shaft mounted on it. The wire pulling sleeve is fixed to the drive shaft. A drive frame is mounted on the upper surface of the processing table, and a drive screw is mounted on the drive frame. A threaded sleeve is fitted onto the drive screw, and the threaded sleeve meshes with the drive screw. A limit shaft is provided at the lower end of the drive screw, and a limit groove is opened on the upper surface of the limit shaft. A limit strip is provided on the lower surface of the threaded sleeve, and the limit strip is inserted into the limit groove. A wire-passing sleeve is provided on the upper surface of the limit strip.

[0011] As a further technical solution, an output motor is provided on the side wall of the support frame. The output end of the output motor is fixedly connected to the drive shaft. A drive wheel is mounted on the drive shaft, a driven wheel is mounted on the drive screw, and a transmission belt is mounted on the drive wheel and the driven wheel.

[0012] As a further technical solution, the auxiliary limiting component includes a support tube, which is disposed on the upper end face of the processing table. A driving cavity is opened in the support tube, and a driving column is inserted into the driving cavity. A locking groove is provided on the inner side wall of the driving cavity. A transverse limiting frame is provided at the upper end of the driving column, and a locking pin is provided on the driving column, which is inserted into the locking groove.

[0013] As a further technical solution, a support platform is provided on the upper end face of the drive column, and the lateral limiting frame is provided on the upper end face of the support platform.

[0014] As a further technical solution, the cable guide sleeve has a cable insertion slot on its top.

[0015] As a further technical solution, the drive shaft is movably connected to the support frame via a bearing, and the drive screw is movably connected to the drive frame via a bearing.

[0016] As a further technical solution, the lower end face of the limiting strip is provided with sliding strips on both sides, and the sliding strips are embedded inside the limiting groove.

[0017] As a further technical solution, the locking groove is composed of multiple horizontal grooves and a vertical groove spliced ​​together, and the vertical groove extends out of the upper end face of the support tube.

[0018] As a further technical solution, the inner walls of both the drive wheel and the driven wheel have a groove structure, and the transmission belt is embedded in the groove structure.

[0019] As a further technical solution, the top of the lateral limiting frame has a wiring insertion port.

[0020] The beneficial effects of the embodiments disclosed herein are as follows:

[0021] 1. In this disclosure, the output motor drives the drive shaft to rotate, which in turn drives the cable pull sleeve to rotate. At the same time, the drive screw and the threaded sleeve cooperate to realize the axial movement of the cable pull sleeve, accurately and efficiently feeding the cable into the cable pull sleeve for processing. Compared with the traditional manual cable feeding method, it greatly shortens the operation time and reduces manpower input. Taking a conventional power operation as an example, using this new type of cable pull sleeve can shorten the cable feeding and installation time by about 30%, greatly improve the overall progress of power operation, enable power facilities to be put into use faster, reduce the power outage time caused by construction, and ensure the stability of power supply for users.

[0022] 2. In this disclosure, the design of locking pins and locking slots precisely fixes the transverse limiting frame in the appropriate position, effectively preventing the cable from shifting or shaking during processing and use. At the same time, the cable insertion slot design of the cable sleeve and the wire embedding port at the top of the transverse limiting frame can play a good limiting role for the cable, ensuring that the cable is always in the correct position and reducing the safety risks caused by improper cable routing. In actual use scenarios, this can effectively avoid problems such as friction and short circuits with other components caused by cable shaking, improve the safety and stability of power operations, and provide reliable safety protection for power workers and the surrounding environment.

[0035] like Figures 1-4 As shown, it illustrates a guy wire sheath for power work according to this disclosure, comprising:

[0036] Processing table 1, with a pull wire sleeve 2 provided on the upper surface of processing table 1;

[0037] Drive wire feeding assembly 3, which is mounted on processing table 1;

[0038] Auxiliary limiting component 4 is disposed on the upper end face of the processing table 1;

[0039] The drive wire feeding assembly 3 includes a support frame 3-1, a drive shaft 3-2 is mounted on the support frame 3-1, a wire pull sleeve 2 is fixed on the drive shaft 3-2, a drive frame 3-3 is mounted on the upper surface of the processing table 1, a drive screw 3-4 is mounted on the drive frame 3-3, a threaded sleeve 3-5 is fitted on the drive screw 3-4, the threaded sleeve 3-5 meshes with the drive screw 3-4, a limit shaft 3-6 is mounted on the lower end of the drive screw 3-4, a limit groove 3-7 is opened on the upper surface of the limit shaft 3-6, a limit strip 3-8 is mounted on the lower surface of the threaded sleeve 3-5, the limit strip 3-8 is inserted into the limit groove 3-7, and a wire guide sleeve 3-9 is mounted on the upper surface of the limit strip 3-8.

[0040] The auxiliary limiting component 4 includes a support tube 4-1, which is set on the upper end face of the processing table 1. A driving cavity 4-2 is opened in the support tube 4-1, and a driving column 4-3 is inserted in the driving cavity 4-2. A locking groove 4-4 is provided on the inner side wall of the driving cavity 4-2. A transverse limiting frame 4-5 is provided on the upper end of the driving column 4-3. A locking pin is provided on the driving column 4-3, and the locking pin is inserted into the locking groove 4-4.

[0041] In some examples, the support frame 3-1 is installed at a suitable position on the machining table 1, and fastened to the machining table 1 using bolts or other connectors to ensure that the support frame 3-1 is perpendicular to the upper surface of the machining table 1 and is stable and does not wobble. Bearings are installed on the support frame 3-1, and the drive shaft 3-2 is movably connected to the support frame 3-1 through the bearings, allowing the drive shaft 3-2 to rotate freely on the support frame 3-1. Then, the pull cable sleeve 2 is fixed to the drive shaft 3-2, using key connections, interference fits, or other methods, to ensure that the drive shaft 3-2 rotates synchronously with the pull cable sleeve 2. The drive frame 3-3 is installed on the upper surface of the machining table 1, its position matching that of the support frame 3-1 to ensure smooth subsequent transmission. A bearing is installed on the moving frame 3-3, and the drive screw 3-4 is movably connected to the drive frame 3-3 through the bearing, so that the drive screw 3-4 can rotate freely on the drive frame 3-3. The threaded sleeve 3-5 is fitted onto the drive screw 3-4 to ensure good meshing between the threaded sleeve 3-5 and the drive screw 3-4. When the drive screw 3-4 is rotated, the threaded sleeve 3-5 can move smoothly along the axial direction of the drive screw 3-4. A limiting shaft 3-6 is installed at the lower end of the drive screw 3-4, and a limiting groove 3-7 is accurately opened on the upper end face of the limiting shaft 3-6. A limiting strip 3-8 is installed on the lower end face of the threaded sleeve 3-5 so that the limiting strip 3-8 can be smoothly inserted into the limiting groove 3-7. A wire guide sleeve 3-9 is installed on the upper end face of the limiting strip 3-8.

[0042] Install the support tube 4-1 on the upper end face of the processing table 1, and fasten it to the processing table 1 with bolts or other connectors to ensure that the support tube 4-1 is perpendicular to the upper end face of the processing table 1. The drive cavity 4-2 is pre-cut in the support tube 4-1. Insert the drive column 4-3 into the drive cavity 4-2. Set the locking groove 4-4 on the inner side wall of the drive cavity 4-2. Install the locking pin on the drive column 4-3 so that the locking pin can be inserted into the locking groove 4-4, thereby locking the position of the drive column 4-3 in the drive cavity 4-2.

[0043] like Figures 1-4 As shown, in this embodiment, the side wall of the support frame 3-1 is provided with an output motor 3-10. The output end of the output motor 3-10 is fixedly connected to the drive shaft 3-2. A drive wheel 3-11 is mounted on the drive shaft 3-2. A driven wheel 3-12 is mounted on the drive screw 3-4. A transmission belt 3-13 is mounted on the drive wheel 3-11 and the driven wheel 3-12.

[0044] In some examples, if the side wall of the support frame 3-1 is equipped with an output motor 3-10, the output motor 3-10 is installed in the predetermined position of the support frame 3-1 and fastened with bolts, etc. The output end of the output motor 3-10 is fixedly connected to the drive shaft 3-2, which can be done by a coupling or other connection method. The drive wheel 3-11 is mounted on the drive shaft 3-2, and the driven wheel 3-12 is mounted on the drive screw 3-4. Ensure that the drive wheel 3-11 and the driven wheel 3-12 are firmly installed. Then, the transmission belt 3-13 is mounted on the drive wheel 3-11 and the driven wheel 3-12. Note that the inner sidewalls of the drive wheel 3-11 and the driven wheel 3-12 are grooved structures. The transmission belt 3-13 should be accurately embedded in the grooved structure to ensure stable power transmission.

[0045] For example, such as Figure 1 As shown, a support platform 5 is provided on the upper end face of the drive column 4-3, and a transverse limiting frame 4-5 is provided on the upper end face of the support platform 5.

[0046] In some examples, a support platform 5 is installed on the upper surface of the drive column 4-3, and then the lateral limiting frame 4-5 is installed on the upper surface of the support platform 5. The support platform 5 supports the lateral limiting frame 4-5, making the lateral limiting frame 4-5 more secure and stable when the wire passes through.

[0047] For example, such as Figure 1 As shown, the cable guide sleeve 3-9 has a cable insertion slot 6 on its top. The cable insertion slot 6 is located on the top of the cable guide sleeve 3-9. The drive shaft 3-2 is movably connected to the support frame 3-1 via a bearing, and the drive screw 3-4 is movably connected to the drive frame 3-3 via a bearing.

[0048] In some examples, the cable slot 6 is located at the top of the cable guide sleeve 3-9. When installing the cable guide sleeve 3-9, ensure that the cable slot 6 is in the correct position to facilitate cable insertion and guidance.

[0049] For example, such as Figure 3 As shown, sliding bars 7 are provided on both sides of the lower end face of the limiting bar 3-8, and the sliding bars 7 are embedded inside the limiting groove 3-7.

[0050] In some examples, to ensure that the limiting strip 3-8 slides smoothly in the limiting groove 3-7, sliding strips 7 can be provided on opposite sides of the lower end face of the limiting strip 3-8 so that the sliding strips 7 are embedded in the interior of the limiting groove 3-7.

[0051] For example, such as Figure 4 As shown, the locking groove 4-4 is composed of multiple horizontal grooves and a vertical groove, which extends out of the upper end face of the support tube 4-1.

[0052] For example, such as Figure 2 As shown, the inner walls of both the drive wheel 3-11 and the driven wheel 3-12 have groove structures, and the transmission belt 3-13 is embedded in the groove structure.

[0053] For example, such as Figure 1 As shown, the top of the lateral limiting frame 4-5 has a wiring insertion port 8.

[0054] In some examples, for ease of use, a wiring insertion port 8 is provided at the top of the transverse limiting frame 4-5. The locking groove 4-4 is composed of multiple transverse grooves and a vertical groove. The vertical groove extends out of the upper end face of the support tube 4-1. When it is necessary to adjust the height of the drive column 4-3 in the drive cavity 4-2, the locking pin can be pulled out from the current transverse groove, the drive column 4-3 can be moved along the vertical groove to the appropriate position, and then the locking pin can be inserted into the corresponding transverse groove to lock the height of the drive column 4-3.

[0055] When in use, start the power source (output motor 3-10) of the drive wire feeding assembly 3. The drive shaft 3-2 drives the pull sleeve 2 to rotate, and at the same time, the drive screw 3-4 rotates, causing the threaded sleeve 3-5 and the wire guide sleeve 3-9 to move along the axial direction of the drive screw 3-4. The cable is fed into the pull sleeve 2 for processing under the drive of the wire guide sleeve 3-9. Continuously observe the operation of the drive wire feeding assembly 3 and the auxiliary limit assembly 4. Pay attention to whether there is any slippage in the transmission belt 3-13 between the drive wheel 3-11 and the driven wheel 3-12. If slippage is found, the equipment should be stopped immediately, the belt tension should be adjusted, and at the same time, check whether the locking pin is always in the locked state to prevent the drive column 4-3 from moving accidentally during operation.

[0056] Adjust the auxiliary limiting component 4 according to the height and position of the cable. If it is necessary to raise or lower the height of the horizontal limiting frame 4-5, first pull the locking pin on the drive column 4-3 out of the horizontal groove of the current locking groove 4-4, and then move the drive column 4-3 up and down along the vertical groove to adjust the horizontal limiting frame 4-5 to a suitable height. If the cable position is high, the drive column 4-3 can be moved upward, and vice versa. After adjustment, insert the locking pin into the corresponding horizontal groove to lock the position of the drive column 4-3. At the same time, ensure that the wire insertion port 8 at the top of the horizontal limiting frame 4-5 is aligned with the cable position so that the cable can be smoothly inserted into the wire insertion port 8, which plays a limiting role.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
