Vehicle lift has important effect in automotive servicing field, by lifting machine by height extremely suitable for vehicle lifting, convenient for maintaining personnel detect vehicle bottom, repair and the positioning correcting of tire, and along with the fast development of Vehicle Industry, the use of lifting machine is also increasingly extensive.Lifting platform is the heavy vital part of lifting machine, during lifting machine work, lifting platform carries the larger weight of vehicle, and lifting platform normally drives it to be elevated by oil cylinder haulage cable, if steel rope ruptures in lifting process, dropping of lifting platform can be caused, vehicle occur and topples, cause the loss of manufacturer, maintaining unit and car owner, even jeopardize the personal safety of maintainer.
For solving problems, Chinese patent 201320445477.1, discloses a kind of lifting machine steel wire rope fracture prevention safety device, belongs to a kind of safety device, specifically, is a kind of steel wire rope fracture prevention safety device for lifting machine.The utility model provides a kind of lifting machine steel wire rope fracture prevention safety device, be arranged on the crossbeam of lifting machine, the crossbeam of lifting machine is slidably mounted between former and later two columns, and the vehicle-carrying plate of lifting machine is arranged between adjacent two crossbeams, is arranged in crossbeam for driving the steel rope of beam lifting.Lifting machine steel wire rope fracture prevention safety device can in steel rope generation fracture or when coming off, trigger the constraint that guide wheel departs from steel rope, retracing spring is made to pull frizzen, trigger board is made to depart from the binary pair of limit switch, thus triggering limit switch, make the controller be connected with limit switch control lifting machine to quit work, when preventing at wire cable rupture or come off, lifting machine work on cause device inclined, cylinder piston rod fracture, danger such as vehicle drops, lifting machine collapses on vehicle-carrying plate.When steel rope guide wheel makes lifting machine be elevated, steel rope stable movement, triggers anti-breaking safety device when avoiding lifting machine normally to work, and affects the normal work of lifting machine.But this utility model just can be made a response after wire cable rupture, and complex structure, the maintenance in later stage and maintenance are all comparatively bothered.
Utility model content
For solving above-mentioned Problems existing, the purpose of this utility model is to provide a kind of reaction in time, and structure is simple, easy to use, the Anti-breakage device of steel wire rope that protected effect is good.
For achieving the above object, the technical solution of the utility model is:
A kind of Anti-breakage device of steel wire rope, comprising: device for testing tensile force and safety device;
Device for testing tensile force, comprise sensor, steel wire rope tension tester, sensor is fixed on steel rope, and is connected to steel wire rope tension tester;
Safety device, comprise control panel, limit switch, pressure spring, security bar, limit switch is connected with control panel by data line, controlled by control panel, pressure spring is positioned at limit switch side, and when limit switch is in cut out, pressure spring is contraction state, lifting machine is fixed in described security bar one end, and the other end is positioned at the opposite side of the pressure spring of limit switch.
Again, described limit switch has energizing signal bar, and this energizing signal bar can regulate within the specific limits.
Further, the angle that described security bar can eject is 90 °.
Further, the surrounding of described limit switch, pressure spring, security bar is provided with stay bearing plate.
Separately, the material selection rubber of described security bar.
The beneficial effects of the utility model are:
Carried out the tension force of Real-Time Monitoring steel rope by sensor, in steel wire rope tension generation significant change, but now steel rope might not rupture, and can start safety device.Effectively can make pre-judgments to the fracture of steel rope, avoid wire cable rupture and cause toppling of vehicle, and structure is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is the overall schematic that a kind of Anti-breakage device of steel wire rope of the present utility model is arranged on lifting machine.
Fig. 2 is the partial enlarged drawing at 2 places in Fig. 1.
In figure, each sequence number is expressed as:
1 is device for testing tensile force; 11 is sensor; 12 is steel wire rope tension tester; 2 is safety device; 21 is control panel; 22 is limit switch; 23 is pressure spring; 24 is security bar; 25 is energizing signal bar.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, further describe below in conjunction with drawings and Examples.
See Fig. 1, Fig. 2, Fig. 1, Fig. 2 are a kind of Anti-breakage device of steel wire rope described in the utility model, comprising: device for testing tensile force 1 and safety device 2;
Device for testing tensile force 1, comprise sensor 11, steel wire rope tension tester 12, sensor 11 is fixed on steel rope, and is connected to steel wire rope tension tester 12;
Safety device 2, comprise control panel 21, limit switch 22, pressure spring 23, security bar 24, limit switch 22 is connected with control panel 21 by data line, controlled by control panel, pressure spring 23 is positioned at limit switch 22 side, and when limit switch 22 is in cut out, pressure spring 23 is contraction state, lifting machine is fixed in described security bar 24 one end, and the other end is positioned at the spacing opposite side opening pressure bullet 21 spring of 22 passes.
Again, described limit switch 22 has energizing signal bar 25, and this energizing signal bar 25 can regulate within the specific limits.
Further, the angle that described security bar 24 can eject is 90 °.
Further, the surrounding of described limit switch 22, pressure spring 23, security bar 24 is provided with stay bearing plate.
Separately, the material selection rubber of described security bar 24.
When lifting machine normally works, by sensor 11, the steel wire rope tension that steel wire rope tension tester 12 records maintains in a range of stability, and now control panel 21 controls limit switch 22 and closes, pressure spring 23 is in contraction state, and the security bar 24 of pressure spring 23 side does not flick.And once the steel rope abrasion of lifting machine is seriously by rupturing, can significant change be there is in steel wire rope tension, by sensor 11, this change is recorded by steel wire rope tension tester 12, then, control panel 21 controls limit switch 22 and opens in time, and the pressure spring 23 being originally in contraction state flicks due to the security bar 24 of elastic reaction by one, timely locking slide unit motion, avoids because wire cable rupture causes vehicle to topple.
By the tension force utilizing sensor 11 to carry out Real-Time Monitoring steel rope, in steel wire rope tension generation significant change, but now steel rope might not rupture, and can start safety device 2.Effectively can make pre-judgments to the fracture of steel rope, avoid wire cable rupture and cause toppling of vehicle, this lifting machine Anti-breakage device of steel wire rope structure is simple, easy to use.
It should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted.Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical scheme of utility model or equivalent replacement, and not departing from the scope of technical solutions of the utility model, it all should be encompassed in right of the present utility model.
