Description

Technical Field

[0001] This utility model relates to the field of tensioner technology, specifically a tensioning device for overhead lines in high-altitude and low-temperature environments. Background Technology

[0002] In power construction, after high-altitude power lines are erected, workers use tensioning devices, or wire tensioners, to tighten the lines. However, in existing high-altitude power line erection systems, especially in low-temperature environments, the mechanical components of these tensioning devices are prone to jamming and freezing due to the low temperatures, leading to operational difficulties. Coupled with environmental factors, operation is extremely inconvenient. Furthermore, when using the device, operators often manually control it to leverage the ratchet, indirectly coming into contact with the power lines and posing a risk of electric shock. Therefore, a tensioning device for power line erection in high-altitude, low-temperature environments is needed. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a tensioning device for overhead lines in high-altitude and low-temperature environments, which can avoid device jamming, improve operating efficiency, prevent electric shock, and improve operational convenience.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tensioning device for overhead lines in high-altitude and low-temperature environments, comprising a frame, a ratchet provided on the frame, a handle provided at the end of the ratchet, a bolt provided at one end of the frame, a first hook provided at the other end, a second hook connected to the bolt, an insulating rope wound around the ratchet, the insulating rope being connected to the first hook, an antifreeze component screwed onto the end of the bolt, the antifreeze component including a handle, a threaded hole at the end of the handle, a piston bottle screwed into the threaded hole, and the piston bottle being filled with antifreeze.

[0005] In some embodiments, the handle is provided with an arcuate portion.

[0006] In some embodiments, the outer surface of the handle is coated with an insulating varnish.

[0007] In some embodiments, the handle is made of rubber and has raised dots on its surface.

[0008] In some embodiments, the end of the piston bottle facing the bolt is the nozzle, and the other end is the piston.

[0009] In some embodiments, a porous plug is installed on the nozzle portion.

[0010] In summary, this utility model has the following beneficial effects:

[0011] This utility model is equipped with an antifreeze component. The handle in the antifreeze component not only helps the operator control the device and gain leverage when using the device handle to turn the ratchet to tighten the line, improving operational convenience, but also prevents the operator's hands from directly contacting the device, thereby eliminating the risk of electric shock. Furthermore, the antifreeze component can be used to pre-spray antifreeze onto the device, ensuring that the device can operate smoothly and without jamming in low-temperature environments, thus improving operational efficiency.

[0015] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and 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 should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0018] See Figure 1-2 A tensioning device for overhead power lines in high-altitude and low-temperature environments includes a frame 1, a ratchet 11 on the frame 1, a handle 5 at the end of the ratchet 11, a bolt 12 at one end of the frame 1 and a first hook 4 at the other end, a second hook 2 connected to the bolt 12, an insulating rope wound around the ratchet 11 and connected to the first hook 4, and an antifreeze component 6 screwed onto the end of the bolt 12. The antifreeze component 6 includes a handle 61, a threaded hole 62 at the end of the handle 61, a piston bottle 63 screwed into the threaded hole 62, and antifreeze fluid filled in the piston bottle 63.

[0019] Using the above-mentioned tensioning device, the operator can not only use the handle 61 in the antifreeze part 6 to pick up the device, but also avoids the need to use the handle 5 to pick it up. There is no need to worry about the handle 5 turning during picking up the device, which would cause inconvenience. When using the device, the operator can use one hand to hold the handle 61 to control the frame 1 for leverage, and the other hand can turn the handle 5, avoiding direct contact between the operator's hand and the frame 1, eliminating the risk of electric shock, and improving the convenience of operation. In addition, at low temperatures, the operator can rotate the handle 61 to remove the handle 61 from the bolt 12, and then press the piston bottle 63 to spray the antifreeze in the piston bottle 63 onto the frame 1, ratchet 11 and insulating rope, thereby preventing the ratchet 11 from getting stuck during use and increasing the difficulty of operation. When using the device to tension the wires, the operation is the same as the operation of the existing wire tensioner, and will not be described in detail here.

[0020] In some embodiments, the handle 61 is provided with an arcuate portion 64. When the operator holds the handle 61, their fingers can be placed on the arcuate portion 64, thereby improving the operator's grip strength and ensuring that the operator can firmly hold the handle 61.

[0021] In some embodiments, the outer surface of the handle 5 is covered with an insulating coating. This prevents the operator from accidentally touching the device and causing electric shock, thus ensuring safe use.

[0022] In some embodiments, the handle 61 is made of rubber and has raised dots on its surface. The raised dots increase the friction between the handle 61 and the operator's hand, thereby ensuring that the handle 61 will not slip out of the operator's hand during operation and ensuring operational efficiency.

[0023] In some embodiments, the end of the piston bottle 63 facing the bolt 12 is the nozzle, and the other end is the piston. When the operator uses the piston bottle 63 to spray antifreeze, pressing the piston will spray out the antifreeze. To add antifreeze, simply insert the nozzle of the piston bottle 63 into the antifreeze, and pull the piston to draw the antifreeze into the piston bottle 63. The operation is simple and convenient.

[0024] In some embodiments, a porous plug is installed on the nozzle. The porous plug enables the sprayed antifreeze to spread out, thereby increasing the spray range of the antifreeze and improving the antifreeze effect of the device.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
