Background technology
Along with the fast development of China's economy, the lifting market scale constantly enlarges, and has stimulated the especially fast development of elevator machinery product of construction machinery and equipment.In hoisting operation, nonstandard operation can make the load hook steel rope produce skewness, and this phenomenon of tiltedly hanging is easy to hoisting crane is caused damage, even brings larger economic loss, has had a strong impact on the normal operation of hoisting crane.Therefore, the deflection of effectively controlling the load hook steel rope is rationally to utilize an important guarantee of crane job, and in the existing weight-lifting equipment, also has the anti-oblique drawing device of a great deal of not configuration.
At present, more on the market is anti-bias anti roll device for hoister in large tonnage such as overhead and gantry cranes, container handling cranes, for the suspension hook steel rope deviation detecting device of arm derrick crane seldom, provided a kind of suspension hook steel rope beat detecting device in the patent 200920091574.9, need to use infrarede emitting diode and infrared receiving diode, its detection is subject to external interference, and can not determine the direction of steel rope generation deflection, can not accomplish to detect separately the deflection of steel rope on left and right directions.
Summary of the invention
Goal of the invention: in order to solve the technical matters in the above-mentioned background technology, a kind of suspension hook steel rope deflection left and right sides detecting device is provided, its principal feature is to realize the detection of suspension hook steel rope on the skew direction of the left and right sides, and this device has adopted mechanically operated form in whole transmission process, simple for structure, detect reliable.
The technical scheme that adopts: a kind of suspension hook steel rope deflection left and right sides detecting device is provided, has comprised: suspension hook steel rope ways 1, rotation connecting rod 2, arm hinge ear 3, oscillating bearing 4, fork 5, weight connecting rod 6, angle potentiometer 7, zeroing position member 8; Suspension hook steel rope ways 1 is installed on the suspension hook steel rope that hoists, and with the rotation connecting rod 2 be connected, rotation connecting rod 2 ends are connected with flange on the zeroing member 8 by bolt, thereby rotation connecting rod 2 connects as one with zeroing position member 8, and do identical rotation, and zeroing position member 8 links to each other with angle potentiometer 7 axles, and angle potentiometer 7 is fixedly mounted on the weight connecting rod 6, weight connecting rod 6 is connected with fork 5 by bearing pin, and fork 5 is connected with arm hinge ear 3 by oscillating bearing 4; The gravity of weight connecting rod 6 is kept fork 5 and is turned to vertical position around oscillating bearing 4, and left and right directions is vertical, and fore-and-aft direction swings.
Wherein, the upper end of described suspension hook steel rope ways 1 links to each other with the crane arm head.
Wherein, described suspension hook steel rope ways 1 links to each other with rotation connecting rod 2 by the hinge ear.
Beneficial effect: the utility model has adopted the framing members such as weight connecting rod, oscillating bearing, has guaranteed that the zero-bit of potential device can overlap with vertical direction, thereby can detect exactly the left and right sides angle excursion of steel rope; In addition, this device is installed in the below of jib head lifting pulley group, and the rotation length of connecting rod can according to the practical structures adjustment, effectively utilize the space of jib head; Whole apparatus structure is simple, and is convenient and easy, satisfied crane market to the detection of suspension hook steel rope deflection on left and right directions.
Description of drawings
Fig. 1 is the structural representation of the utility model suspension hook steel rope deflection left and right sides detecting device.
The accompanying drawing sign: 1-suspension hook steel rope ways, 2-rotates connecting rod, 3-arm hinge ear, 4-oscillating bearing, 5-fork, 6-weight connecting rod, 7-angle potentiometer, 8-zeroing position member.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is elaborated.
With reference to Fig. 1, in the present embodiment, a kind of suspension hook steel rope deflection left and right sides detecting device comprises: suspension hook steel rope ways 1, rotation connecting rod 2, arm hinge ear 3, oscillating bearing 4, fork 5, weight connecting rod 6, angle potentiometer 7, zeroing position member 8; Suspension hook steel rope ways 1 links to each other with the jib head, and be enclosed within on the suspension hook steel rope that hoists, realize that suspension hook steel rope ways 1 carries out identical motion with steel rope, and with the rotation connecting rod 2 be connected, rotation connecting rod 2 ends are connected with flange on the zeroing member 8 by bolt, thereby rotation connecting rod 2 connects as one with zeroing position member 8, and do identical rotation, zeroing position member 8 links to each other with angle potentiometer 7 axles, and realize that angle detects, when the zero-bit of angle potentiometer 7 during not at vertical direction, can be contained on the member of zeroing position the zeroing function that 8 flange is realized angle potentiometer 7 by adjustment, angle potentiometer 7 is fixedly mounted on the weight connecting rod 6, and weight connecting rod 6 is connected with fork 5 by bearing pin, and fork 5 is connected with arm hinge ear 3 by oscillating bearing 4; The gravity of weight connecting rod 6 is kept fork 5 and is turned to vertical position around oscillating bearing 4, left and right directions is vertical, and fore-and-aft direction swings, and the zero-bit of angle potentiometer 7 is stabilized in vertical position, when the suspension hook steel rope swings, can accurately detect the angle of deviation of steel rope left and right directions.
