Embedded tensioner

Abstract

The invention discloses an embedded tensioner which is simple in structure and high in strength and comprises a support seat. A ratchet shaft wound with a movable end of a wire is rotationally arranged on the support seat, tension ratchets are arranged at two ends of the ratchet shaft, a backstop pawl capable of being matched with the tension ratchets is arranged on the support seat, a fixing hole for a fixed end of the wire and a fixing hole for the movable end of the wire are respectively arranged on the support seat and the ratchet shaft, the wire fixing tension direction of the fixing hole for the fixed end of the wire is positioned on the perpendicular bisector of the ratchet shaft between the tension ratchets, and the fixing hole for the movable end of the wire is penetratingly arranged on the ratchet shaft between the two tension ratchets at the two ends of the ratchet shaft and is deviated from the center of the ratchet shaft. The embedded tensioner has the advantages that a deficiency gap of small field embedded tensioners for metal wires in China is filled, and the embedded tensioner is high in hardness and toughness, low in service cost and good in service effect and is corrosion-resistant when used in a field.

Description

technical field [0001] The invention relates to a tensioner, in particular to a high-strength field embedded tensioner for tensioning metal wires and the like. Background technique [0002] At present, the tensioner (also called tensioner) in China is large in size, and it is a one-time tensioner when it is used for tensioning metal wires. Because of its large volume, complex structure and high cost, it is severely corroded in the field and cannot be used for a long time. It is very difficult to operate when it is to be tightened many times, and it is difficult to implement. [0003] To sum up, this type of tensioner has a setting method of the tensioning wheel shaft, which makes its bearing capacity low, resulting in insufficient strength of the tensioned metal wire; for some thin plate-shaped support seats, the structural strength is not enough, and it will appear during use. The distortion and deformation of the support base lead to the scrapping of the product; the trad...

Because of its large size, complex structure and high cost, it is severely corroded in the field and cannot be used for a long time. It is very difficult to operate when it needs to be tightened many times, and it is difficult to implement

[0003] To sum up, this type of tensioner has a setting method of the tensioning wheel shaft, which makes its bearing capacity low, resulting in insufficient strength of the tensioned metal wire; for some thin plate-shaped support seats, the structural strength is not enough, and it will appear during use. The distortion and deformation of the support base lead to the scrapping of the product; the traditional tensioner is generally made of metal material, so that the tensioning of the metal wire can only be applied to the tensioning of the non-electric metal wire, and cannot be applied to some live wires. wire tensioning work, etc.
