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
The present invention relates generally to a kind of for industrial circle, and is rational in infrastructure, the stacker crane body beat detecting sensor that safety coefficient is higher.
Background technology
The deviant of stacker crane body center line is to be related to the normally important parameter of trouble free service of tower crane, causes that the factor of this parameter variation is a lot, and this parameter is a union variable, so all extremely important to detection and the control of this parameter.Present detection and control still follow method and technology decades ago, far can not satisfy the requirement of technology high-speed development, so the present invention design the angular transducer that a kind of employing is heavily put.
After tower machine body of the tower was installed, (only relevant with manufacturing accuracy and installation accuracy) body of the tower axis was to side direction verticality≤4/1000 of carrying plane under the situation that not influenced by external force, and just body of the tower axis top is with respect to the displacement≤4H/1000 of theoretical axis; Another is to lift by crane corresponding rated load weight in a certain amplitude, and the horizontal off-position of lifting beam root moves and should be not more than H/100.Be that scale is fixed near the junction of body of the tower and lifting beam with regard to these 2 present general detection method of content, use the transit survey shift value then.This method poor operability, the time used during measurement is longer, and it is more difficult especially to measure this numerical value when body of the tower is higher, brings big workload and labour intensity to the testing staff simultaneously.If can there be a device to place body of the tower and jib junction, can directly demonstrate deflection and shift value, to bring great convenience to testing, can increase work efficiency and measuring accuracy, can alleviate reviewer's labour intensity again, normally the carrying out of work for inspection in the time of simultaneously also solving transit and can't measure can detect and monitor at any time, and assurance equipment can be used safely.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of for commercial production, applying flexible, stacker crane body beat detecting sensor simple in structure.
Major technique characteristics of the present invention are: be made of mounting flange, iron core, weight, cotton rope, top unshakable in one's determination arranges a mounting flange, link to each other by screw between its iron core and the mounting flange, two groups of telefaults are set on its iron core, center unshakable in one's determination arranges an armature rod, and armature rod below links to each other with weight by cotton rope.
Beneficial effect of the present invention is: the degree of accuracy height is 0.2%; The resolution height, reach ± 1 "; Simple in structure, volume is little, uses easy to adjustly, is suitable for in-site measurement; Particularly use gravity pendulum as sensitive element, technology maturation, simple and reliable, angular transducer accuracy height, good endurance; All the other electric genus spare dependable performances, and be not subjected to the influence of working environment.
Description of drawings:
Fig. 1 is product structure principle schematic of the present invention
Fig. 2 specifically practices figure for the present invention
Embodiment:
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail
As shown in Figure 1: stacker crane body beat detecting sensor is made of mounting flange 1, iron core 2, weight 5, cotton rope 7,2 tops unshakable in one's determination arrange a mounting flange 1, link to each other by screw 6 between its iron core 2 and the mounting flange 1, two groups of telefaults 3 are set on its iron core 2,2 centers unshakable in one's determination arrange an armature rod 4, and armature rod 4 belows link to each other with weight 5 by cotton rope 7.
Stacker crane body beat detecting sensor is installed in the tower crane pilothouse by through hole in the mounting flange 1, unshakable in one's determination 2 are connected by screw 6 with mounting flange 1, two telefaults 3 (Z1 and Z2) embed respectively in unshakable in one's determination 2, armature rod 4 by rope hanging at the mounting flange center, weight 5 of armature rod 4 rear suspensions.
2 is iron cores among Fig. 1, is wound with two telefaults 3,4th on it respectively, the armature rod, and when armature rod 4 during with measured object generation beat, the air-gap on both sides has increment respectively | Δ δ |.Two telefaults are connected into the electric bridge mode during measurement, see Fig. 2, and brachium pontis is respectively Z1, Z2, R1, R2, power supply loads at " A ", " B " two ends, sensor is output as Δ V, in certain range ability, and bridge output voltage Δ V and beat displacement increment | Δ δ | linear.
The present invention can a responsive plane in the banking motion of any direction, its balance staff links to each other with the armature rod of angular transducer, the shell flange of sensor links to each other with body of the tower, be fixed on the appropriate location during detection, when body of the tower had deflection or swing, because the heavily pendulum in the system remains the plumb position, and the shell of sensor was with body of the tower deflection or swing, so heavily pendulum forms the drift angle with shell, and in fact this angle is exactly the angle of body of the tower deflection or swing.In order to get rid of the influence that inertia produces, can give heavily suitably increase damping of pendulum, to limit its inertia motion.The drift angle is detected by angular transducer, and illustrates with the size of voltage Δ V with corresponding polarity, and this signal just can draw the distance of position deflection and the swing of surveying, and be shown by display device after exchanging amplification, demodulation, power amplification, demarcation.
