Embodiment Construction

[0022] see figure 1 , figure 2 , The torque control device of the present invention includes two sets of electronic torque controllers I-1, I-2, which are respectively installed on the webs on both sides of the transition section above the upper support of the pole.

[0023] The electronic torque controller 1 includes a casing 1, a mounting base 2, a connecting bolt 4, a torque difference sensor 5, a connecting plate 6 and a pin 7.

[0024] One end of the torque difference sensor 5 is fixed on the upper end of the mounting base 2 with a pin 7 through the connecting plate 6 , and the other end is connected to the lower end of the mounting base 2 through the connecting bolt 4 . The installation base 2 is welded on the transition section web bar 3 above the upper support of the double rocker arm pole, and the cover 1 is fixed on the installation base 2 by bolts to prevent rain.

[0025] The electronic torque controller 1 measures the tensile deformation of the main chord paren...

Abstract

The invention discloses a moment control device arranged on a double rocker arm type holding pole. The moment control device is characterized by comprising two groups of electronic moment controllers, and the electronic moment controllers are respectively arranged on two sides of a mast for determining and controlling actual moment difference between two rocker arms. The electronic moment controllers are employed to sense deformation tension F of a main chord, unbalance moment M is calculated and compared with precalibrated unbalance moment, and the moment difference is limited by restricting motion direction of each mechanism to protect balance of the double rocker arm type holding pole when corresponding control points are reached. The moment control device has simple control method and can effectively ensure safe use of the double rocker arm type holding pole.

Description

technical field [0001] The invention relates to a torque control device and a control method for a double rocker arm holding pole. [0002] The so-called floor-standing double rocker arms, the tower body is assembled from several standard sections, upper and lower supports, and masts from bottom to top. The two rocker arms are symmetrically installed on the upper support of the tower body. The hook is connected by a wire rope, and the floor-standing double rocker arm pole is used to lift heavy objects symmetrically. When the standard section is installed to a certain height, connect the pole-holding tower body and the power tower with a waist ring and a stay wire; when the joint reaches a certain height, set a second waist ring and stay wire; , and then set a number of waist rings and wiring, in this way to maintain the stability and normal lifting of the pole. [0003] Pole-holding structure composition: the pole-holding tower body is composed of a standard section, a reinf...
