Description
Technical field
The utility model relates to a kind of tower crane stock degree of tilt monitoring device, the especially monitoring device of stock degree of tilt in the tower crane lifting operation process.
Background technology
From the jacking tower crane in the jacking operation; The high-strength bolt (or bearing pin) that (arm, balance arm, cat head, rotary support, stock etc.) up and down is connected with standard knot because tower machine upper is removed; Its top weight is by the jacking crossbeam or climb pawl and bear; The unbalanced moment that balance arm and arm produce then acts on the standard knot through the stock guide wheel, and when the uneven degree in both sides was excessive, one-sided stock guide wheel will be stressed excessive; Influence the serviceable life of guide wheel, influence the operation of jacking operation simultaneously.In the operation of reality; The workpeople normally comes the moment of flexure of balance both sides through the position of dolly; And dolly to be this open toward external-open or toward in, this inclination situation that just needs the jacking operating personnel to observe stock is judged, the eyes that have only the workman that can rely in this course at present; So inefficiency, there is potential safety hazard in it.
The utility model content
The utility model technical matters to be solved is to overcome deficiency of the prior art and a kind of tower crane stock degree of tilt monitoring device is provided; The utility model can be in tower machine jacking process, when arm and the balance arm both sides are uneven, when stock produces, it is to tilt or tilt toward the balance arm direction toward the arm direction that the workman can judge stock easily; Thereby can adjust the position of dolly fast; The moment of flexure of balance both sides guarantees stock guide wheel gap, guarantees the verticality of stock.
The technical scheme that the utility model solves the problems of the technologies described above employing is: this tower crane stock degree of tilt monitoring device, and the two ends that are arranged in pairs in the stock crossbeam is characterized in that near the position of climbing pawl: a cover tower crane stock degree of tilt monitoring device comprises support, slip cap, slide block, connecting link, compression spring, adjustment nut, roller; Adjustment bolt and microswitch, described support is welded on the stock crossbeam, is fixed with slip cap on the support; Two adjustment bolts are installed on the slide block, and slide block and connecting link one end are fixed, and slide block moves and is arranged in the slip cap; The connecting link other end is provided with roller, and roller contacts with tower machine standard knot main chord, and compression spring is sleeved on the connecting link; The adjustment nut is twisted and is connected on the connecting link; One end of compression spring contacts with the adjustment nut, and the other end of compression spring contacts with slip cap, and two microswitches are installed on the slip cap; Be separately fixed at the both sides of slide block, two microswitches are electrically connected with two vergence direction pilot lamp respectively.
One end of described slide block of the utility model and connecting link is fixed through hold-down nut.
The described roller of the utility model is fixed on the connecting link through hold-down nut.
Both sides are separately installed with an adjustment bolt on the described slide block of the utility model, and two microswitch positions that are provided with on the slip cap are with to adjust bolt position corresponding, and under the stock plumbness, each microswitch is identical with spacing between the corresponding adjustment bolt.
The utility model compared with prior art has the following advantages: the utility model is accomplished by two cover stock degree of tilt monitoring devices jointly; It is through judging the degree of tilt in the plane of stock jacking cylinder direction; And the light on and off of inclination situation through the vergence direction pilot lamp are shown intuitively; Can judge very easily stock be towards which side to inclination, thereby remind operating personnel, the position of convenient adjustment dolly.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The installation of the utility model: Fig. 1 medium-height trestle 2 is welded on the stock crossbeam 1; The both sides of slide block 5 are installed an adjustment bolt 12 respectively; Slide block 5 is fixed through hold-down nut 6 with connecting link 7 one ends; Fixedly rear slider 5 is filled in slip cap 3, and connecting link 7 other ends are fixed with roller 10 through hold-down nut 6, and roller 10 contacts with standard knot main chord 11.Slip cap 3 is through being bolted on the support 2, and with compression spring 8 by the connecting link 7 that is inserted in shown in Figure 1, be screwed into adjustment nut 9, compression spring 8 one ends contact with slip cap 3, compression spring 8 other ends with adjust nut 9 and contact.Two microswitches 4 are installed on the slip cap 3, are separately fixed at the both sides of slide block 5, and corresponding one by one with adjustment bolt 12 on the slide block 5, microswitch 4 be used to judge stock in the jacking position to two tilt situation.Tower crane stock degree of tilt monitoring device is totally two covers, is installed in the two ends of stock crossbeam respectively, relatively near the position of climbing pawl, thus the depth of parallelism of judgement stock main chord and standard knot main chord, the vergence direction of affirmation stock.
The adjustment of the utility model: in the initial installation process of tower machine, after stock installs, need adjustment stock guide wheel gap, assurance stock vertical rod (main chord) is identical with each side clearance of standard knot main chord.After adjust in stock guide wheel gap, adjustment tower crane stock degree of tilt monitoring device.The one, adjustment adjustment nut 9 makes pulley 10 be pressed on standard knot main chord 11, and adjustment adjustment bolt 12 then makes clearance control between microswitch contact and the adjustment bolt in stock allows the zone of reasonableness of inclination.Under the stock plumbness, each microswitch 4 is identical with spacing between the corresponding adjustment bolt 12.
The principle of work of the utility model: when in tower machine jacking process; Because the uneven inclination that can produce stock of arm side and balance arm side; When the imbalance of both sides surpasses zone of reasonableness when balance arm tilts, the roller 10 in the tower crane stock degree of tilt monitoring device will tilt and 11 of standard knot main chords produce the gap because of stock, and whole connecting link 7 and roller 10 will eject under the acting force of compression compression spring 8; The continuation maintenance contacts with standard knot main chord 11; And connecting link 7 drive slide blocks 5 move, and touch microswitch 4, and are bright with the pilot lamp that microswitch 4 is electrically connected; Inform the vergence direction of operating personnel's stock, thereby operate accordingly.Otherwise when stock tilts towards opposite side, roller 10 will be compressed into by standard knot main chord 11, and slide block 5 will touch an other microswitch 4, light pilot lamp, accomplish prompt facility.
Above content described in this instructions only is to be illustrated what the utility model structure did.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; Only otherwise depart from the structure of the utility model or surmount the defined scope of these claims, all should belong to the protection domain of the utility model.
