Description
Technical field
The present invention relates to technical field of crane equipment, particularly relate to a kind of real-time monitoring device of hoisting equipment steel rope.
Background technology
The flapping issue of suspender, it is the problem making lifting industry design and commissioning staff's headache always, hoisting crane is when handling goods, due to the change of its speed and the impact of external interference factor, make swinging back and forth of suspender all around, while affecting production efficiency, cause certain potential safety hazard, finally cause serious economic loss.
At present, hoisting equipment prevent the means of shaking have artificial anti-to shake, machinery anti-ly shakes, electronic anti-swinging etc.Wherein machinery is anti-shakes and is divided into anti-the shaking of hydraulic efficiency pressure system to prevent shaking with suspension; Electronic anti-swinging is divided into again open loop control system and closed loop control system to prevent shaking.Numerously above anti-shake mode, artificial anti-shaking depends on experience too much, poor stability, machinery is anti-shakes complex structure, fault rate is high, and open loop system is anti-shakes then poor anti jamming capability, and anti-the shaking of closed loop control system rests on the Computer Simulation stage mostly, and field working conditions is complicated, for practical application brings very large difficulty.
Summary of the invention
The object of the invention is the technological deficiency for existing in prior art, and a kind of real-time monitoring device of hoisting equipment steel rope is provided.
The technical scheme adopted for realizing object of the present invention is:
A kind of real-time monitoring device of hoisting equipment steel rope, comprise controller, the hinged upper connecting rod of upper jointed shaft is passed through with the swing arm front end of weight-lifting equipment, by the hinged lower link of middle jointed shaft and described upper connecting rod lower end, be arranged on the sleeve of lower link lower end, be fixedly connected with swing arm and the upper end coder that is fixedly connected with upper jointed shaft of S. A., be fixedly connected with upper connecting rod and the middle-end coder that is fixedly connected with middle jointed shaft of S. A., described upper jointed shaft and the perpendicular setting of middle jointed shaft, described upper end coder is connected with controller communication respectively with middle-end coder, sleeve described in the steel wire penetrating of described hoisting equipment is also connected with suspender.
Described weight-lifting equipment is door machine, and described upper end free bearing fixed type is arranged on trunk beam front end.
The swing arm front end of weight-lifting equipment is provided with upper end free bearing, described upper connecting rod by upper jointed shaft and described upper end free bearing hinged, described upper end coder is fixedly installed on the free bearing of upper end.
Upper connecting rod lower end is fixedly installed middle-end free bearing, described lower link by middle jointed shaft and described middle-end free bearing hinged, described middle-end coder is fixedly installed on middle-end free bearing.
Lower end and the sleeve of described lower link are articulated and connected by horizontal shaft.
Described sleeve designs so that steel rope is accommodated therein for opposite opened.
Described coder is absolute type encoder.
Compared with prior art, the invention has the beneficial effects as follows:
Structure of the present invention is simple, is convenient to install, without the need to doing any improvement to weight-lifting equipment, practical.Major part is two absolute encoders, just can be grasped the shake state of steel rope by the output of their signals, and the suitable speed in conjunction with some positioners control motor just can reach well anti-and shake effect.
Accompanying drawing explanation
Figure 1 shows that the structural representation of the real-time monitoring device of hoisting equipment steel rope of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, the real-time monitoring device of hoisting equipment steel rope of the present invention, comprise controller, be fixedly installed on the swing arm front end of weight-lifting equipment, as the upper end free bearing of the trunk beam front end of door machine, the hinged upper connecting rod 1 of upper jointed shaft is passed through with described upper end free bearing 11, be fixedly installed on the middle-end free bearing 21 of connecting rod lower end, the hinged lower link 2 of middle jointed shaft is passed through with described middle-end free bearing, hingedly be arranged on the sleeve 3 of described lower link lower end, described upper end free bearing with middle-end free bearing are fixedly installed upper end coder 12 and middle-end coder 22 respectively that be connected with described controller communication, be preferably absolute type encoder, model OCD-58310-AP112.Upper end coder is fixedly connected with lower jointed shaft with the upper jointed shaft of perpendicular setting respectively with the S. A. of middle-end coder, and described upper end coder and middle-end coder are connected to feed back amount of spin with controller communication respectively; Sleeve described in the steel wire penetrating of described hoisting equipment, passing for ease of steel rope, general sleeve diameter 2mm larger than the diameter of steel rope.Preferably, sleeve designs so that steel rope is accommodated therein for opposite opened, and namely sleeve is the two halves split, and side is hinged, and opposite side is locked by locking mechanism, which enhances installation convenience.
Upper free bearing is arranged on the trunk beam front end of hoisting equipment, makes steel wire penetrating sleeve, when steel rope is when swinging, middle-end coder also can rotate thereupon, can grasp the angle swung like this by the output of coder; When steel rope swing time, upper connecting rod swing, is driven upper end coder to rotate, can be grasped the angle of steel rope swing by the output of upper end coder.Export by the rotation of upper end and middle-end coder the shake situation can determining steel rope, gather the output signal of two coders, by suitable controlled reset, just can reach the object preventing steel rope from shaking.
Structure of the present invention is simple, is convenient to install, without the need to doing any improvement to weight-lifting equipment, practical.Major part is two absolute encoders, just can be grasped the shake state of steel rope by the output of their signals, and the suitable speed in conjunction with some positioners control motor just can reach well anti-and shake effect.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
