Description
Technical field
The utility model relates to a kind of manufacturing line safety guard, and in particular, it relates to a kind of jacking being used on lifting body safety guard that puts in place.
Background technology
In the workshop of production enterprise, there is various conveyor line, wherein have on a lot of conveyor lines and will use lifting body, common lifting body mode has electric machine control, air operated control and fluid control, in process of production, when object is lifted to eminence holding position, can there is the risk of the displacement that declines in lifting body, for example, because the unexpected power-off of motor or liquid/gas cylinder pressure cylinder body are revealed and are caused the loss of lifting body confining force, cannot bear object weight, lifting body automatic descending, to personnel and equipment right may damaging all.At present, a lot of motors are all provided with fender guard, once power-off just enters band-type brake state, if lifting body adopts this motor to be used as power, during prominent chance power-off, lifting body can be locked on the spot, thereby without worrying lifting body automatic descending.And if liquid/gas presses the liquid/gas cylinder pressure body on the lifting body of class to reveal, pipeline liquid/gas is pressed and is difficult to keep so, lifting body is slowly and not controllably decline also.So liquid/gas presses the lifting body of class also should adopt some fender guards to guarantee safe in operation.Publication number is that the utility model of CN202022634U discloses a kind of safety protecting device of hoister on November 2nd, 2011; comprise that one group is used for promoting the conveying device pinning of track limit position with the conveying device automatic locking mechanism of fall arrest by being pulled through above, this conveying device automatic locking mechanism comprises to be located at the lock part on conveying device and to be installed in the hanging hook assembly that lifting track top can fasten with lock part.The utlity model has simple in structure, esy to use, safe and reliable, can effectively prevent that conveying device is in promoting the offside advantage such as fall of track end position.But this utility model structure is slightly aobvious complicated, and transmission device wherein takes up an area larger, may not be applicable to application for the workshop of some industry.
utility model content
In order to overcome pneumatic type lifting body easily because cylinder is revealed the defect that lifting body automatic descending occurs; the utility model provides a kind of and can after object is put in place by lifting body jacking, to lifting body, support, prevent that lifting body from surprisingly declining and personnel and equipment are damaged the jacking safety guard that puts in place.
The technical solution of the utility model is: a kind of jacking safety guard that puts in place; be located at by lifting body; comprise that support, swinging support bar and strut bar drive cylinder; strut bar drives cylinder block to be articulated with on support, and another point on the bottom of swinging support bar and swinging support bar drives the piston rod of cylinder hinged with support and strut bar respectively.Swinging support bar can swing, when this device is not worked, strut bar drives cylinder piston rod to retract, in swinging support bar, receive, after lifting body puts object jacking in place, strut bar drives cylinder piston rod to stretch out, promoting swinging support bar rotates around swinging support bar bottom, swinging support bar is outwards put, move on to the object supporting plate below of lifting body, once lifting body can not be fixed holding position because of pipeline leakage insufficient pressure, swinging support bar just stops that in rigid support mode lifting body declines, and guarantees can not cause safety misadventure.
As preferably, the top of swinging support bar is provided with a roller.Swinging support masthead end is rolled and contacts with lifting body by roller, can improve the local pressure situation of swinging support bar and lifting body object supporting plate contact part, also can avoid the component wear that directly hard contact causes.
As preferably, support is step, is articulated with frame bottom, and strut bar drives cylinder block to be articulated with a top of the trellis.This jacking safety guard that puts in place need to be arranged on the manufacturing line of lifting body; the existing mutually perpendicular driving surface of step support; can provide the driving surface that has diff-H again, be convenient to make the access of this device to be incorporated on manufacturing line, and the rational deployment of the parts of arranging work.
As preferably, frame bottom is installed with a hinge support connecting panel, hinge support connecting panel is provided with at least two levels and the bolt regulating tank parallel with the plane of oscillation of swinging support bar, in bolt regulating tank, be provided with bolt, hinged block connecting panel is connected with a hinge support by described bolt, and the bottom of swinging support bar is hinged on hinge support.Hinge support can change installation site along bolt regulating tank, thereby can change the swing inclination angle of swinging support bar, to adapt to better the top lifting height of lifting body.
As preferably, the position that swinging support bar and strut bar drive the piston rod of cylinder to be hinged is positioned at the middle and upper part of swinging support bar.Once lifting body automatic descending, being subject to swinging support bar supports, on swinging support bar, be applied in a pressure moment, the position that swinging support bar and strut bar drive the piston rod of cylinder to be hinged is more top, it is relatively longer to the arm of force of swinging support bar bottom resting point that strut bar drives the piston rod of cylinder, strut bar drives the suffered pulling force of cylinder piston rod just less, just higher for cylinder safety factor, yet, if pursue simply near swinging support masthead end at the position that swinging support bar and strut bar drive the piston rod of cylinder to be hinged, the amplitude of oscillation of swinging support bar can reduce again, therefore, consider, the position that swinging support bar and strut bar drive the piston rod of cylinder to be hinged is positioned at the middle and upper part of swinging support bar, take into account strut bar and drive the stress value margin f sefety of cylinder piston rod and the amplitude of oscillation of swinging support bar.
As preferably, controlling strut bar drives the electromagnetic valve of cylinder to be connected with a PLC signal, strut bar drives cylinder block to be provided with the limit sensor that detects respectively the flexible state of cylinder piston rod, limit sensor is connected with described PLC signal, described lifting body is provided with high position sensor and the low sensors that detects respectively top lifting height end position and falling-threshold position, and this high position sensor and low sensors are also connected with described PLC signal.This device adopts automatically and controls, outer pendulum and the interior time receiving machine of controlling strut bar are controlled according to the action command sending after sample information processing by PLC, only have PLC to obtain the signal that lifting body jacking that high position sensor sends puts in place, PLC just can drive the electromagnetic valve of cylinder send the action command that cylinder stretches out to controlling strut bar; Equally, only have PLC to be supported signal that bar drives cylinder piston rod retraction that cylinder block limes superiors sensor sends to put in place, PLC just can send the instruction that lifting body is fallen to the drive system of lifting body.This device adopts automatic control greatly to increase work efficiency, and alleviates labor intensity of operating staff.
The beneficial effects of the utility model are:
Reliable in function, can strengthen the safety precaution to lifting body.The utility model can provide hardware support to lifting body, can stop to die suddenly, the reason such as gas leakage, power-off causes lifting body automatic descending, and then cause equipment damage and personnel's injury, has guaranteed the safety of equipment operation.
Simple in structure, be easy to be attached on manufacturing line.The utility model is totally a leverage, usings cylinder as operation power, simple in structure, takes up an area littlely, can access and be incorporated in manufacturing line at an easy rate.
