Problems solved by technology

[0003] The fixed tension measurement and control equipment has the following problems and limitations: First, the fixed tension measurement and control equipment can only measure and control the tension and tensile strength of the material alone, but cannot simultaneously measure and control the tension of the stretched object and install it
Second, the fixed tension measurement and control equipment cannot be moved due to size, power supply and placement requirements, so the use environment is limited
The third is that the fixed tension measurement and control equipment is expensive and expensive to use, which affects its popularization

Embodiment Construction

[0041] The present invention will be further described below in conjunction with accompanying drawing.

[0042] In this embodiment, a hypothetical unmanned aerial vehicle is taken as an example. The length of the fuselage is 7 meters and the wingspan is 8 meters. The front wheel is installed on the U-shaped front wheel bracket. The mounting seat at the lower part of the drop frame has bearings in the mounting seat, which can make the front wheel bracket rotate horizontally. A rocker arm is installed along the wingspan direction at the part where the mounting seat is exposed on the upper part of the vertical shaft. The length is the same as that of the stop arm fixed on the front landing gear and located at the same height as the front 75mm of the rocker arm, and the left and right symmetrical distribution. The stop arm is fixed on the front landing gear. When the rocker arm rotates horizontally, it will drive the front wheel bracket and the front wheel to rotate together. Both...

Abstract

The invention provides a stay wire tension controller which comprises a stay wire measurement and control mechanism, a stress mechanism, a sensor support block and a bracket, wherein the bracket comprises a base and a vertical wall; the base and the vertical wall form a structure of which the cross section is L-shaped; the stress mechanism is arranged at the middle lower position of the vertical wall; the stay wire measurement and control mechanism comprises a drill chuck, a tension sensor, a guide jacket, a force transfer screw rod and a corrugated hand wheel; the front end of the tension sensor is connected with the drill chuck through a double-end bolt; the rear end of the tension sensor is connected with the force transfer screw rod; the guide jacket and the corrugated hand wheel are arranged on the force transfer screw rod; a brass gasket is arranged between the guide jacket and the corrugated hand wheel; the stay wire measurement and control mechanism is clamped into an opening groove in the upper end of the vertical wall through the guide jacket; and up-and-down position adjustment is achieved through the sensor support block for clamping a sliding key groove formed in the vertical wall. According to the stay wire tension controller, the tension of the stay wire can be monitored and controlled accurately in real time; the operation process of tensioning the stay wire is safe and stable; and synchronous tension measurement and control and installation of the stay wire can be achieved.

Description

technical field [0001] The invention belongs to the technical field of tension measurement and control, and relates to a portable manual tension measurement and control precision device for simultaneously performing tension measurement, control and installation of one or two stretching objects, which cannot be realized on fixed tension measurement and control equipment. In particular, it relates to a cable tension controller. Background technique [0002] Whether in the field of military or civilian product production, it is possible to encounter cable installation work that needs to be installed and fixed at a certain part of the product with a predetermined tension in advance. At present, all tension measurement and control work involving materials requires the use of fixed tension measurement and control equipment. Finish. [0003] The fixed tension measurement and control equipment has the following problems and limitations: First, the fixed tension measurement and cont...
