Abstract
The utility model discloses a hydraulic lifting platform prevents weighing down control mechanism, including wire rope, pulley, travel switch and weight, wire rope is on locating the pulley, and wire rope's one end links to each other with travel switch, and the weight links to each other with travel switch. Platform lift in -process, during the platform does not descend if take place the hydro -cylinder to descend the condition, wire rope is soft, and the weight descends under the action of gravity, and travel switch breaks off, controls the hydro -cylinder stop motion to just can effectively avoid the emergence of incident, eliminate the potential safety hazard, further strengthen hydraulic lifting platform's operational safety ability.
Description
Technical field
This utility model is related to hydraulic lifting technical field, specifically a kind of anti-fall for hydraulic elevating platform
Controlling organization.
Background technology
At present, hydraulic elevating platform typically by oil cylinder come the lifting of control platform.But in actual moving process, often
Oil cylinder can be occurred to decline and situation that hoistable platform does not decline, thus leading to accident to occur, there is larger potential safety hazard.
Content of the invention
Technical problem to be solved in the utility model is that proposing one kind can be prevented effectively from security incident, further enhance
The anti-fall controlling organization of the hydraulic elevating platform of operational safety performance.
For solving above-mentioned technical problem, a kind of anti-fall controlling organization of hydraulic elevating platform of this utility model includes steel wire
Rope, pulley, travel switch and weight, described steel wire rope is set around on described pulley, one end of described steel wire rope and described stroke
Switch is connected, and described weight is connected with described travel switch.
The other end of steel wire rope, due to employing above-mentioned technical pattern, is connected to hydraulic lifting during application by this utility model
The platform of platform stretches and (can be connected in the stage casing that platform stretches steel wire rope on steel wire rope；If hydraulic elevating platform has left and right two
Individual drawing mechanism, then can respectively connect this utility model controlling organization on the platform stretching steel wire rope of arranged on left and right sides), will go
Cheng Kaiguan is connected with the decline driving means of hydraulic elevating platform.During lifting platform, decline and platform in the event of oil cylinder
During situation about not declining, platform stretching steel wire rope is soft, and the steel wire rope in this utility model mechanism is also simultaneously soft, and weight will
Decline under gravity, travel switch disconnects, thus controlling decline driving means to quit work, oil cylinder stop motion, hydraulic pressure
Hoistable platform quits work, and thus effectively prevent the generation of security incident, eliminates potential safety hazard, further enhancing fortune
Row security performance.
Brief description
Fig. 1 is the structural representation of the anti-fall controlling organization of this utility model.
Specific embodiment
As shown in figure 1, the anti-fall controlling organization of this utility model hydraulic elevating platform includes steel wire rope 1, pulley 2, stroke
Switch 3 and weight 4, steel wire rope 1 is set around on pulley 2, and one end of steel wire rope 1 is connected with travel switch 3, and weight 4 and stroke leave
Close 3 to be connected.During use, the other end of steel wire rope 1 is connected on the platform stretching steel wire rope 5 of hydraulic elevating platform, by stroke
Switch 3 be connected with the decline driving means of hydraulic elevating platform (i.e. the device of control cylinder 6 lifting) (such as with conventional at present
Electromagnetic valve in the Hydraulic Station that control cylinder is run about 6 is connected).In hydraulic elevating platform running, when under generation oil cylinder 6
Fall and during situation that platform 7 does not decline, the wire wheel 8 being fixed on oil cylinder 6 top declines, and the platform being set around on wire wheel 8 draws
Stretch that steel wire rope 5 is soft, the steel wire rope 1 being attached thereto is simultaneously soft, and weight 4 will decline under gravity, travel switch 3 breaks
Open, thus controlling decline driving means to quit work (if being connected with the electromagnetic valve of Hydraulic Station, then closed electromagnetic valve), oil cylinder
6 stop motions, hydraulic elevating platform will quit work, thus avoiding security incident.
Claims (1)
1. a kind of hydraulic elevating platform anti-fall controlling organization it is characterised in that it include steel wire rope, pulley, travel switch and
Weight, described steel wire rope is set around on described pulley, and one end of described steel wire rope is connected with described travel switch, described weight with
Described travel switch is connected.
