Detailed description of the invention
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1, Fig. 1 provides by utility model the structural representation of a kind of detailed description of the invention of principal arm angular stop means.
In a kind of detailed description of the invention, integrated chemoprevention provided by the utility model is crossed to face upward and is put principal arm angular stop means, forms primarily of parts such as base 1, pointer 2, first bent plate 31, second bent plate 32, first proximity switch 71, second proximity switches 72.
Wherein, base 1 is 90 ° fan-shaped in central angle substantially, peripheral position is provided with five mounting holes, pointer 2 upper end and base 1 are rotationally connected formation center of oscillation at circle centre position, lower end can freely swing around center of oscillation and hold and the angle index region pointed in the middle part of base, the angular dimension of angle index region instruction principal arm and turntable, simultaneously as one reference during adjusting proximity switch, angular range is from 0 ° to 90 °, according to the difference of installation site, its scale value can increase from right to left gradually, also can increase gradually from left to right.
Particularly, pointer 2 is close to the position of lower end rounded or spherical (also can be other shapes), to make its center of gravity as much as possible on the lower, thus have under gravity and better swing performance, pointer 2 upper end is rotationally connected with base 1 by stud 4 and bolt 5, during installation, first stud 4 is vertically welded on base 1, then adopts bolt 5 to screw in stud 4 through the through hole of pointer 2 upper end.
First bent plate 31 is fixed on base 1; between pointer 2 center of oscillation and angle index region; which is provided with first chute 61 slightly wider than pointer 2 thickness; the shaft of pointer 2 is through described first chute 61; freely swing in the scope that can limit at the first chute 61; first bent plate 31 1 aspect is used for the range of movement of limit pointer 2, has a kind of protective effect on the other hand to pointer 2.
Second bent plate 32 is also fixed on base 1, be positioned at the below in angle index region, arc length and radius are all greater than the first bent plate 31, which is provided with the second chute 62, second chute 62 is divided into independently two sections, lay respectively at both sides, for the first proximity switch 71 and the second proximity switch 72 that installation site is adjustable, the swinging track of pointer 2 lower end is positioned within the detection range of the first proximity switch 71 and the second proximity switch 72, proximity switch directly contacts just can realize connecting circuit without the need to carrying out machinery with movable parts pointer, thus sends detection signal.
Here, the first chute 61 and the second chute 62 are the slotted hole that the length direction along bent plate circular arc is offered.Certainly, except slotted hole, chute can also be other forms, such as, can process " U " shape groove in advance on the first bent plate 31 and the second bent plate 32, when it is fixed on base 1, closes " U " shape channel opening form chute by base 1; Or two sections of connections of the second chute 62 are a slotted hole, etc.
The center of circle of above-mentioned first bent plate 31, second bent plate 32 overlaps with the center of oscillation of pointer 2, and namely three has the same center of circle.
Second chute 62 is for installing and adjusting proximity switch, first proximity switch 71 and the second proximity switch 72 are arranged in the second chute 62 respectively by fastener, its test side is upwards exposed, corresponding to pointer 2 lower end, the other end and wire are drawn downwards, when the needs adjusting proximity switch position, and first loosening fasteners, then with reference to the scale value of angle scale zone, proximity switch is slid into suitable position in the second chute 62, then tightening fastener parts again.
Please refer to Fig. 2, Fig. 3, Fig. 2 is installed on the schematic diagram of main arm of crane for the angular stop means of principal arm shown in Fig. 1; Fig. 3 is the close-up schematic view at A position in Fig. 2.
As shown in the figure, principal arm angular stop means is arranged on the left surface of main arm of crane root, substantially identical with the installation site of detecting device in prior art, a stacked block-shaped similar welded plate 9 below its base 1, base 1 is installed on welded plate 9 by five mounting holes, and welded plate 9 is welded on principal arm 10 together with the principal arm angular stop means on it.
The luffing of principal arm 10 is driven by the hoisting rope of turntable 11 inside, in working order, the operating range of principal arm 10 is confined, and principal arm 10 is crossed and faced upward, and has the danger that crawler crane is tumbled, principal arm 10 is crossed and is put, and exceeds the scope of the performance table of crawler crane, cannot work on.
After the above-mentioned principal arm angular stop means of employing, during principal arm 10 luffing, its pointer 2 swings along with the change of principal arm angle, when swinging to directly over the first proximity switch 71, first proximity switch 71 responds, when swinging to directly over the second proximity switch 72, the second proximity switch 72 responds.
Please refer to Fig. 4, Fig. 4 is the control flow chart of the angular stop means of principal arm shown in Fig. 1.
As shown in the figure, when the first proximity switch 71 responds, restriction principal arm 10 continues luffing downwards, prevents the performance table scope exceeding crawler crane; When the second proximity switch 72 responds, restriction principal arm 10 upwards continues luffing, prevents crawler crane from tumbling.
The integrated design of the utility model is conducive to the modularization system type of series of products, improve the overall aesthetics of turntable front portion, reduce design cost and tooling cost, the weldering time is joined at the scene of decreasing, improve work efficiency, substantially increase the installation positioning precision of inhibiting device simultaneously.
Certainly, above-described embodiment is only preferred version of the present utility model, is specifically not limited thereto, and can make pointed adjustment according to actual needs on this basis, thus obtain different embodiments.Such as, base designs is become other shapes, or the position of proximity switch carries out regulating etc. by other means.Because mode in the cards is more, just casehistory no longer one by one here.
Except above-mentioned principal arm angular stop means, the utility model also provides a kind of crawler crane, the principal arm comprising turntable and be rotationally connected with described turntable, and the side of described principal arm is provided with principal arm angular stop means mentioned above, all the other structures please refer to prior art, repeat no more herein.
Cross to face upward to integrated chemoprevention provided by the utility model above and put principal arm angular stop means and crawler crane is described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands core concept of the present utility model for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
