Description
Technical field
The invention belongs to the inhibiting device technical field that hoisting crane runs, specifically, the present invention relates to one and prevent turning over buffering earth anchor.
Background technology
The frequent phenomenon occurring being blown off by wind or slip away of the rail-mounted weight-lifting equipment (abbreviation hoisting crane) of operation out of doors.Then the terminal block of hoisting crane high-speed impact track, finally breaks terminal block, causes serious accidents such as derailing or topple, bring great loss, and the person in serious threat, goods part, the safety of equipment to society.
The wind prevention braking measure existed on the market now, adopts direction of travel in orbit to arrange the method cushioning terminal block above more; When hoisting crane traveling speed is too fast, because hoisting crane center of gravity is higher, bottom it after collision buffering gear, suddenly stop, having the possibility of overturning.
Application number is 92225486.9, title is the utility model patent of " anti-wind and turn-over-proof localizer for portal jib crane ", its structure is as shown in Figure 7, Figure 8: it walks cross girders 2 arranged outside locating bush 500 at hoisting crane, arranges detent mechanism 100 in track 23 side corresponding to locating bush 500; Detent mechanism 100 is clipped on the friction slide rail 600 bottom track 23 by clamping plate 300; Clamping plate 300 are provided with spring bumper 200.
When this prevents that turning over registration device brakes hoisting crane, first its locating bush 500 is enclosed within the fix shaft 400 of detent mechanism 100, and fix shaft 400 pressuring spring shock absorber 200 once cushions; When spring bumper 200 moves to the limit, spring bumper 200 can drive detent mechanism 100 to slide on friction slide rail 600; Secondary buffer braking is realized by the friction force between detent mechanism 100 and friction slide rail 600.
Thisly anti-turn over registration device there is following shortcoming: 1, locating bush and detent mechanism are arranged on crane track both sides, during operation, if there is weight to fall, locating bush or detent mechanism can be made to damage distortion, locating bush after distortion and detent mechanism are difficult to repair, and cause wholely anti-turn over registration device and cannot using.
2, when cushioning, turning over registration device because this is anti-is realize secondary buffer by the friction force between detent mechanism and friction slide rail, and the gripping power between detent mechanism and friction slide rail immobilizes; Therefore, during its buffering, dynamic load and wearing and tearing can cause cushion effect to reduce gradually; Cause its poor stop, and in the goods yard of hoisting crane, the track of long distance is difficult to realize, if the length of friction slide rail is inadequate, is then difficult to ensure anti-function of turning over location.
3, this prevents that the fix shaft turning over registration device detent mechanism is only when hoisting crane stops, and plays the effect of earth anchor, makes hoisting crane be fixed on registration device place; And when hoisting crane buffer-braking, the anti-tipping function of detent mechanism is poor; This is because hoisting crane center of gravity is higher, and when being subject to cushion effect bottom hoisting crane, the front position of hoisting crane can become rotating shaft when tumbling; This anti-registration device that turns over makes hoisting crane front end by cushion effect, and therefore, locating bush and positioning means contacts place very easily form rotating shaft; If hoisting crane speed is fast, cushion effect large, then likely makes fix shaft be damaged, cause hoisting crane overthrow accident.And if the speed of hoisting crane is fast, cushion effect is little, although the generation of overthrow accident can be avoided, its stopping distance also can significantly extend, and is difficult to reach desirable braking effect.
4, this anti-registration device that turns over needs all to arrange one in the cross girders corner of walking of hoisting crane; Cost is high, and maintenance and debugging is also complicated.
5, the friction slide rail size between clamping plate is comparatively large, and also will process the strip hole of the bolt installing strap on friction slide rail; Its structure cannot be reinforced, and through after a period of time, the impact by natural causes such as wind and weathers can produce distortion, all brings difficulty to operation and maintenance.
Summary of the invention
The present invention is exactly for the problems referred to above, provides a kind of structure simple, is not easily turned over buffering earth anchor by the anti-of eminence pendant thing damage.
For realizing above-mentioned purpose of the present invention, the present invention adopts following technical scheme, the present invention includes and be arranged at hoisting crane and walk slideway bottom cross girders, and the earth anchor cover of hoisting crane walking rails side, its structural feature slideway is provided with clamping plate, be fixedly installed spring bumper below clamping plate, the end of spring bumper is provided with push rod; Described earth anchor cover is corresponding with push rod.
As a preferred embodiment of the present invention, the two ends of described spring bumper are provided with push rod.
Further preferred version, described installation of slide track is intermediate thin, and two ends are thick.
Further preferred version, described installation of slide track walks the midway location of cross girders in hoisting crane.
Beneficial effect of the present invention: 1, the present invention is by slideway, spring bumper, and earth anchor cover is all arranged at the bottom that hoisting crane walks cross girders, the weight fallen by eminence also cannot injure the present invention, and therefore, the present invention is not fragile, and maintainability is good.
2, because the two ends of spring bumper of the present invention are all provided with push rod, therefore, no matter hoisting crane to which direction moves, push rod all can and the earth anchor cover corresponding to push rod match, make crane brake; Therefore, compared with documents, save two cover shock attenuation devices, make cost be reduced to the half of former cost.
3, because installation of slide track of the present invention is intermediate thin, two ends are thick, and when installing clamping plate, be installed on by clamping plate in the middle of slideway, during crane brake, clamping plate slide on slideway; Along with the increase of slideway thickness, its braking force also can increase gradually; And while braking force increases gradually, the speed of hoisting crane also can slow down fast; Like this, the reduction of hoisting crane speed and braking force improve, and ensure that hoisting crane is not easily tumbled, and can stop in extremely short distance.
4, installation of slide track is walked the midway location of cross girders by the present invention in hoisting crane, and when crane brake, earth anchor can drive spring bumper to move along the direction that hoisting crane working direction is contrary on slideway; Earth anchor cover can move to the rear end of hoisting crane; When hoisting crane has the trend of tumbling for axle with the front-wheel of hoisting crane, the spring bumper of hoisting crane rear end can fix on the ground by earth anchor cover firmly, reaches better anti-tipping object.
