Embodiment Construction

[0009] The present invention will be described in further detail below in conjunction with accompanying drawing and specific embodiment

[0010] like figure 1 Shown: The tower crane deflection detection sensor is composed of a mounting flange 1, an iron core 2, a weight 5, and a wire rope 7. An installation flange 1 is arranged above the iron core 2, and the iron core 2 and the installation flange 1 are connected. Connected by screws 6, two sets of inductance coils 3 are arranged on the iron core 2, an armature rod 4 is arranged at the center of the iron core 2, and the lower part of the armature rod 4 is connected with the weight 5 through a wire rope 7.

[0011] The tower crane deflection detection sensor is installed in the cab of the tower crane through the through hole in the mounting flange 1. The iron core 2 and the mounting flange 1 are connected by screws 6. Two inductance coils 3 (Z1 and Z2) are respectively embedded in the iron core. In 2, the armature rod 4 is sus...

Abstract

The present invention relates to a tower body deflection detection sensor of a tower crane. The tower body deflection detection sensor comprises an installation flange (1), an iron core (2), a weight dropper (5) and a thread rope (7), wherein the installation flange (1) is arranged above the iron core (2), the iron core (2) and the installation flange (1) are connected through screws (6), two sets of inductance coils (3) are arranged on the iron core (2), the center position of the iron core (2) is provided with an iron holding rod (4), and the lower portion of the iron holding rod (4) is connected with the weight dropper (5) through the thread rope (7). The tower body deflection detection sensor has the following advantages that: the technology is mature, simple and reliable, the angle sensor has characteristics of high accuracy and good durability, and performances of the remaining electric metal members are reliable, and are not affected by a working environment.

Description

technical field [0001] The invention mainly relates to a tower crane tower deflection detection sensor with reasonable structure and high safety factor, which is used in the industrial field. Background technique [0002] The deflection value of the center line of the tower crane tower is an important parameter related to whether the tower crane can work normally and safely. There are many factors that cause this parameter to change. This parameter is a combination variable, so the detection of this parameter and Controls are very important. The current detection and control still follows the method and technology decades ago, which is far from meeting the requirements of rapid technological development. Therefore, the present invention designs an angle sensor using heavy pendulum. [0003] After the tower body of the tower crane is installed, under the condition that it is not affected by external forces (only related to manufacturing accuracy and installation accuracy), t...
