The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
The universal detecting device of a kind of suspension hook wire rope inclined-pulling of the present invention comprises: steel rope deflection guiding mechanism, connecting rod mechanism, swing-bar mechanism, automatic rotation detecting; The locating bush 11 of steel rope deflection guiding mechanism fastens orienting sleeve 7, is provided with the orienting sleeve 7 that adapts between steel rope and the locating bush 11, prevents that steel rope abrasion is excessive, adjusts in real time through 15 pairs of orienting sleeves 7 of adjustment means again; Locating bush 11 is provided with some adjustment means 15; Fork 3 upper ends of swing-bar mechanism are provided with oscillating bearing 2, realize that the fork any direction rotates, and the lower end is provided with conductor 6 and potential device or coder 5, and the beat direction is measured; Connecting rod 14 two ends in the link component are provided with hinge, and an end is connected with steel rope deflection guiding mechanism, and the other end is connected with swing-bar mechanism, guarantee that the pendulum angle of steel rope deflection guiding mechanism passes to swing-bar mechanism; Automatically rotation detecting is installed in the bottom of fork 3, further comprises seal bootr 12, swivel 4,1:1 detects or amplification detection mechanism, the automatic spin balancing detent mechanism of perpendicular positioning mechanism 13, plane 1, potential device or coder 5 automatically; Swivel 4 is fixed on the lower end of fork 3; Automatically perpendicular positioning mechanism 13 is connected with two swing gyro-rotors 17 respectively with 1:1 detection or amplification detection mechanism; Seal bootr 12 is fixed on the swivel 4, carries the influence to measuring mechanism to eliminate wind, has effects such as rainproof, dustproof simultaneously; And with swivel 4 rotations, the automatic spin balancing detent mechanism 1 in plane is fixed on the lower end of seal bootr 12.
Said 1:1 detects or amplification detection mechanism mainly comprises coupler 10, measurement of angle potential device 8, gear case 9; There are intermeshing big gear wheel and miniature gears in gear case 9 inside; Measurement of angle potential device 8 is connected with 9 of gears case, and gear case 9 is connected with measurement of angle potentiometer shaft 8 with swivel 4 through coupler 10.
Said connecting rod mechanism comprises four hinges 16 and two connecting rods 14.
Said locating bush 11 adopts the releasable structure, promptly uses two halves formula orienting sleeve 7 to fasten steel rope.
With reference to Fig. 1, in the present embodiment, in order to reduce the friction of steel rope and locating bush 11, adopting material is the orienting sleeve 7 of nylon material.Because the friction coefficient of nylon material and steel rope is less, helps steel rope endwisely slipping in guiding mechanism.
With reference to Fig. 2,, can the pendulum angle of steel rope deflection guiding mechanism be passed to swing-bar mechanism through connecting rod mechanism.The four points of connection of connecting rod mechanism is hinged, can planar deform, and guarantees the parallel of opposite side simultaneously.Therefore, through 14 pairs of transmission of motions of parallelogram connection-rod, can guarantee that servo-actuated fork 3 produces identical pendulum angle with steel rope.Connecting rod mechanism can make installing space increase, and can not influence the winding of steel rope.
With reference to Fig. 3, can know that through above-mentioned analysis swing-bar mechanism can be followed steel rope and produced identical pendulum angle, therefore can be through the mode of measuring oscillating bar pivot angle, indirect measuring steel wire rope pivot angle and beat direction.
Fork 3 is hinged through upper end hole and arm head installing mechanism, through oscillating bearing 2, forms universal structure, with guarantee fork 3 in the space the arbitrarily angled steel rope of following swing; Fork 3 is designed to hollow structure, and cable can be arranged in the centre, thereby avoids that to expose the cable that causes aging and cause cable breakage because of collision because of cable; Conductor 6 on the fork 3 guarantees automatic rotation detecting when rotary oscillation, and angle excursion potential device 8 connecting wires are unlikely to random line, and assurance angle excursion potential device 8 signals are exported smoothly.
Guarantee the swing rotation of swivel 4 and the double action that automatic rotation detecting keeps vertical direction through conductor 6; When the suspension hook steel rope produces beat; Fork 3 can produce relative swing thereupon, and angle excursion potential device 8 is measured the angle of steel rope beat indirectly through measuring this corner.
The installation of potential device or coder 5 can be adopted two kinds of schemes.When fork 3 diameters are enough big, when selected potential device or coder 5 volumes meet the demands, can directly it be installed in fork 3 inside.When potential device or coder 5 are installed inadequately in fork 3 inner spaces, can measure with potential device or coder 5 again setting up for example gear-driven mode fork 3 degreeof turns are drawn above the swivel with below the fork moral.
With reference to Fig. 4, rotation detecting is used for the position of any direction pivot angle of measuring steel wire rope automatically, and the installation of the measurement of angle potential device 8 of steel rope can be taked two kinds of schemes.It is not very high requiring when survey precision, when selected measurement of angle potential device 8 can reach the accuracy requirement of measurement mechanism, can install according to the scheme in left side among the figure.When survey precision is had relatively high expectations, during the accuracy requirement of selected measurement of angle potential device 8 out of reach measurement mechanisms, then install according to figure right-of-center in political views side case.In this scheme, pendulum angle is amplified, can increase the precision of measurement through gear cluster.
Automatically perpendicular positioning mechanism 13 links to each other with measurement of angle potential device (body) 8 through bearing swing gyro-rotor 17, makes bearing swing gyro-rotor and measurement of angle potential device 8 main bodys keep vertical direction.When fork 3 produced horizontal pivot angle, bearing swing gyro-rotor can relatively rotate and the pivot angle angle same with the rotation axon, and measurement of angle potential device 8 is measured the angle that fork 3 is swung indirectly through measuring this corner.Since the automatic spin balancing detent mechanism 1 in plane can confirm automatically the detection side to, so can survey the pivot angle of steel rope any direction.
The present invention is applied on the crawler crane; Steel rope deflection guiding mechanism is connected to hinge ear place, arm head assembly pulley both sides through rope; Fork 3 is hinged through upper end hole and arm head installing mechanism, and when the steel rope beat, the automatic spin balancing detent mechanism 1 in plane is made response; Automatically perpendicular positioning mechanism 13 makes bearing pendular body and potential device 8 main bodys keep vertical direction; Measure this corner through measurement of angle potential device 8 and measure the angle that fork is swung indirectly, last potential device or coder 5 are measured the direction of pivot angle, have so far accomplished the overall process that the steel rope deflection angle is measured.The steel rope deflection maximum pendulum angle number of degrees that the present invention detects are 100 °.
Above content is to combine optimal technical scheme to the further explain that the present invention did, and can not assert that the practical implementation of invention only limits to these explanations.Under the present invention, the those of ordinary skill of technical field, under the prerequisite that does not break away from design of the present invention, simple deduction and replacement can also be made, all protection scope of the present invention should be regarded as.
