Description

Technical Field

[0001] The present application relates to the technical field of power distribution line maintenance, and in particular to a self-locking detection tool lifting rod. Background Art

[0002] Distribution lines are an important part of the power system, and their stable operation directly affects the quality and safety of power supply. The structure of distribution lines generally includes conductors, insulators, hardware and concrete poles, etc. Among them, concrete poles need to bear the static loads of conductors, insulators and hardware, as well as the dynamic loads caused by environmental factors such as wind. Therefore, in the long-term use process, as the pole structure ages, its bearing capacity gradually decreases, which increases the risk of pole tilting or even breaking, threatening power supply safety. In order to ensure the stable operation of distribution lines, it is necessary to regularly inspect and maintain poles.

[0003] In order to facilitate production and transportation, electric poles are generally constructed by segmenting and then splicing them on site. The joints of electric poles are usually fixed by connecting structures such as steel plate rings and flanges. The fracture of electric poles is also prone to occur at the joints. Therefore, the hidden dangers of electric poles are generally checked at the joints. The inspection method is usually to use X-ray machines and other detection tools for inspection.

[0004] Since the inspection position of the pole is high above the ground (generally about 5m), the inspection tooling needs to be transported to the pole connection point by aerial vehicles. However, the use cost of aerial vehicles is high, which is a heavy economic burden for inspection units in some areas. At the same time, aerial vehicles are difficult to operate flexibly in narrow terrain or complex environments, and have low applicability. Summary of the invention

[0005] In view of this, the purpose of this application is to provide a self-locking detection tooling hoisting rod to solve the problems of high economic burden and low applicability of existing pole detection methods.

[0006] In order to achieve the above technical purpose, the present application provides a self-locking detection tooling hanging rod, including: a support rod, a clamping rod, a pulley and a hanging line;

[0007] The clamping rod is arranged at the front end of the supporting rod;

[0008] The clamping rod surrounds to form a clamping groove;

[0009] The clamping groove has an opening through which the power supply rod passes;

[0010] The pulley is arranged on the support rod;

[0011] The hanging line is connected to the detection tooling;

[0012] The pulley is used for the hanging line to pass through, so that the detection tool is hung on the pulley and the height can be adjusted through the hanging line;

[0013] When the detection tool is hung on the pulley, the support rod is subjected to the gravity of the detection tool so that the rear end of the support rod tilts downward, driving the groove wall of the clamping groove to press the electric pole.

[0014] Furthermore, a docking block is provided at the front end of the support rod;

[0015] The docking block extends into the clamping groove, and the front end surface of the docking block is arc-shaped.

[0016] Furthermore, a groove wall of the engaging groove and / or a front end surface of the docking block is provided with a friction reinforcing member.

[0017] Furthermore, the friction enhancing member is a friction pad.

[0018] Furthermore, the friction enhancement member is a sawtooth distributed along the length direction of the clamping rod.

[0019] Furthermore, the inner diameter of the snap-fit ​​groove is adjustable.

[0020] Further, the clamping rod comprises a first arc-shaped rod and a second arc-shaped rod;

[0021] The first arc-shaped rod is fixed to the front end of the support rod;

[0022] The second arc-shaped rod is slidably connected to the first arc-shaped rod, and forms the clamping groove with the first arc-shaped rod;

[0023] A tightening screw is provided at the connection between the first arc-shaped rod and the second arc-shaped rod;

[0024] The tightening screw is used to limit the relative sliding of the first arc rod and the second arc rod when tightening.

[0025] Furthermore, the position of the pulley on the support rod is adjustable.

[0026] Furthermore, the support rod is provided with a plurality of installation holes arranged at intervals along the length direction;

[0027] The pulley is detachably connected to the mounting hole.

[0028] Further, it also includes a butterfly bolt;

[0029] The butterfly bolt passes through the mounting hole and is detachably connected to the pulley.

[0030] It can be seen from the above technical scheme that the present application provides a self-locking detection tooling lifting rod, comprising: a support rod, a clamping rod, a pulley and a hanging line; the clamping rod is arranged at the front end of the support rod; the clamping rod is surrounded to form a clamping groove; the clamping groove has an opening for the power supply pole to pass through; the pulley is arranged on the support rod; the hanging line is connected to the detection tooling; the pulley is used for the hanging line to pass through, so that the detection tooling is hung on the pulley and can adjust the height through the hanging line; when the detection tooling is hung on the pulley, the support rod is subjected to the gravity of the detection tooling, so that the rear end of the support rod is tilted downward, driving the groove wall of the clamping groove to press the electric pole.

[0031] The hoisting rod provided by the present application is easy to manufacture, carry and install, and has higher economic efficiency. During installation, after the clamping rod is connected to the pole and the detection tool is hung on the pulley, the gravity of the detection tool can realize the self-locking fixation of the hoisting rod on the pole, so that the detection tool can detect the pole.

[0042] The technical solutions of the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the specification of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection requested by the present application.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0044] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a replaceable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0045] See also Figure 1 In an embodiment of the present application, a self-locking detection tool lifting rod is provided, including: a support rod 10, a clamping rod 20, a pulley 30 and a hanging line.

[0046] The clamping rod 20 is arranged at the front end of the support rod 10. In practical applications, the hanging rod is horizontally installed on the pole. In the embodiment of the present application, the end of the hanging rod connected to the pole is the front end, that is, Figure 1 and Figure 2 Correspondingly, the other end is the lower end.

[0047] The clamping rod 20 surrounds and forms a clamping groove 21. The clamping groove 21 can be a C-shaped groove or a G-shaped groove. The clamping groove 21 has an opening 22 through which the power supply pole passes. When the hanging rod is installed on the power pole, the opening 22 is aligned with the power pole, so that the power pole passes through the opening 22 and enters the clamping groove 21.

[0048] The pulley 30 is disposed on the support rod 10. The hanging wire is connected to the detection tooling. In practical applications, the hanging wire can be a steel cable or a nylon rope, one end of which is connected to the top of the detection tooling, and the other end passes through the pulley 30 and returns to the ground. The staff can pull the detection tooling up or down by pulling the other end of the hanging wire to adjust the height of the detection tooling.

[0049] After the inspection tool is hung on the pulley 30, the staff pulls the hanging line to hang the inspection tool on the pulley 30. At this time, the inspection tool is in a suspended state, so its gravity will act on the support rod 10. The support rod 10 is subjected to the gravity of the inspection tool, so that the rear end of the support rod 10 tilts downward, driving the groove wall of the clamping groove 21 to press the pole. The opening 22 is close to the pole, forming a self-locking state, ensuring that the hoisting rod is firmly fixed on the pole.

[0050] In this embodiment, the lifting rod can achieve self-locking by detecting the gravity of the tooling. This method makes it unnecessary to set up other locking structures for the lifting rod, thereby effectively simplifying the structure of the lifting rod, reducing manufacturing costs, improving installation efficiency, and improving the convenience of carrying by staff.

[0051] At the same time, the self-locking method can ensure the stability of the hoisting rod after installation. In the practical exploration of the inventor, the friction force generated by the hoisting rod after the detection tooling can meet the needs of fixing it on the pole, specifically, it can meet the hoisting requirements of conventional X-ray machines with a weight of 10-30kg.

[0052] In actual applications, when workers use the hoisting rod provided by this embodiment, they do not need to go through the complex large-scale mechanical operation approval procedures that are generally required when using aerial vehicles, and can perform the inspection process of electric poles in various environments, greatly improving the flexibility of the inspection operation. At the same time, aerial vehicles also have the problems of high purchase cost and high use cost, while this hoisting rod can be more widely provided to various inspection units due to its lightness and low cost, and has wider economic applicability.

[0053] It should be noted that when the hoisting rod provided by this application is used for installation, when the hoisting rod is installed at a medium-low height (4 meters and below) on the pole, the staff can install the hoisting rod on the pole by raising their hands or lifting the hoisting rod through the grounding rod, and after the inspection tooling is hung, the staff let go or remove the grounding rod. It is rare to need to install the hoisting rod in a higher area of ​​the pole (above 4 meters), and when it is necessary to install it, the staff can use a ladder or wear pole climbing tools to install the hoisting rod on the pole, and after the inspection tooling is hung, the staff can safely evacuate from the pole.

[0054] In one embodiment, a docking block 11 is disposed at the front end of the support rod 10 ; the docking block 11 extends into the clamping groove 21 , and the front end surface of the docking block 11 is arc-shaped.

[0055] When the hoisting rod is installed on the pole, the front end surface of the docking block 11 can abut the pole. When the rear end of the support rod 10 sinks due to gravity, the front end surface of the docking block 11 will rise and press the surface of the pole, further enhancing the friction between the hoisting rod and the pole. In this way, the friction between the hoisting rod and the pole can act on the support rod 10 and the clamping rod 20 respectively. Compared with the method of connecting the pole only by the clamping rod 20, the stability of the connection between the hoisting rod and the pole can be further enhanced. Through this double friction design, the hoisting rod can still remain stable when subjected to different weights and wind forces, thereby ensuring the accuracy of the detection tooling.

[0056] In one embodiment, a friction enhancement member is provided on the groove wall of the clamping groove 21 and / or the front end surface of the docking block 11. The friction enhancement member can enhance the friction between the hanging rod and the pole, thereby further improving the stability of the hanging rod.

[0057] As an implementation manner, the friction reinforcement member is a friction pad, which may be a rubber pad.

[0058] As an implementation manner, the friction enhancement member is a sawtooth distributed along the length direction of the clamping rod 20 .

[0059] After the hoisting rod is installed on the pole, the sawtooth structure can be inserted into the pole. When the rear end of the hoisting rod is tilted by gravity, it can be firmly clamped on the pole to achieve stable support for the detection tooling.

[0060] In one embodiment, the inner diameter of the clamping slot 21 can be adjusted to fit poles of different diameters.

[0061] In one embodiment, see Figure 1 and Figure 2The clamping rod 20 includes a first arc rod 201 and a second arc rod 202; the first arc rod 201 is fixed to the front end of the support rod 10; the second arc rod 202 can be slidably connected to the first arc rod 201, and forms a clamping groove 21 with the first arc rod 201; a tightening screw is provided at the connection between the first arc rod 201 and the second arc rod 202; the tightening screw is used to limit the relative sliding of the first arc rod 201 and the second arc rod 202 when tightening.

[0062] The clamping groove 21 is located between the first arc rod 201 and the second arc rod 202. The inner diameter of the clamping groove 21 can be adjusted to adapt to poles of different diameters through the relative sliding of the first arc rod 201 and the second arc rod 202. When the inner diameter of the clamping groove 21 needs to be fixed, it is only necessary to tighten the screws so that the first arc rod 201 and the second arc rod 202 are firmly locked by tightening the screws to ensure that the inner diameter of the clamping groove 21 is stable.

[0063] In one embodiment, the position of the pulley 30 on the support rod 10 can be adjusted to adjust the distance between the detection tooling and the pole after hanging, so as to achieve adaptation to different types of detection tooling.

[0064] As an implementation, see Figure 3 and Figure 4 The support rod 10 is provided with a plurality of installation holes 12 arranged at intervals along the length direction; the pulley 30 can be detachably connected to the installation hole 12.

[0065] By providing the mounting hole 12, after the pulley 30 is installed, the pulley 30 cannot move along the support rod 10 during the hanging process, thereby ensuring stability during the hanging process.

[0066] Furthermore, a butterfly bolt 40 is included; the butterfly bolt 40 passes through the mounting hole 12 and is detachably connected to the pulley 30 .

[0067] The butterfly bolt 40 can be easily adjusted manually by a worker.

[0068] The self-locking detection tool hoisting rod provided in the embodiment of the present application can efficiently and stably perform pole inspections in complex environments, significantly improving work efficiency and safety; at the same time, the hoisting rod does not need to be provided with flanges, steel rings and other connecting structures, but realizes a stable connection between the hoisting rod and the pole by self-locking the gravity of the detection tool, which simplifies the structure and can effectively reduce the cost of production, installation and maintenance, so that the hoisting rod shows excellent practicality and economy in actual applications, and provides reliable technical support for the detection work in the power industry. In addition, structures such as the docking block 11 and the friction reinforcement member in the hoisting rod can enhance the stability of the hoisting rod after being connected to the pole, thereby meeting the hanging requirements of the detection tool and ensuring the stability of the hanging.

[0069] The above are only preferred embodiments of the present application and are not intended to limit the present invention.
