Description
Technical field
The utility model belongs to mgnetic observations technical field, and in particular to a kind of top-opening type detection magnetic force crane gear is pulled
The device of power.
Background technology
Lifting magnet equipment refers to the equipment that load is inhaled using magnetic force, steel material is carried, including lifting electromagnet, lifting
The types such as permanent magnet, permanent magnetic lifter.The pulling-out force of lifting magnet equipment refers to the minimum for mechanically pulling absorbate
Power.Pulling-out force is the important technological parameters for weighing lifting magnet equipment suction size and its security reliability.
In the past, detection magnetic force crane gear pulling-out force was tested using chain block and tensiometer, was not only operated numerous
Trivial, inefficiency, and the larger product of pulling-out force can not be detected.
Later, people started to detect magnetic force crane gear pulling-out force using force tester is pulled.Pulling force tester is
A kind of test platform of gantry type frame, typically using hydraulic transmission mode, pulling-out force is detected by chest expander, test result is led to
Digital instrument is crossed to show.Its test method is that lifting magnet equipment is placed on pulling-out force tester base steel plate, then by magnetic
Power crane gear, which is in, inhales load state.The suspension ring of lifting magnet equipment are hung on chest expander.Chest expander and gantry type frame top
The hydraulic lift in portion is connected.With the rise of lowering or hoisting gear, pulling force numerical value is read from chest expander.When lifting magnet equipment with
When base steel plate is separated, chest expander shows that numerical value is pulling-out force.
But, detect that magnetic force crane gear pulling-out force has a critical defect using force tester is pulled, being exactly will be by
The lifting magnet equipment of inspection is placed into when pulling on force tester, it is impossible to which one-time-reach-place is, it is necessary to artificial assistance.Because inspected magnetic
Power crane gear must be placed at the centre of pulling-out force tester base, and it is gantry type frame structure to pull force tester,
Spandrel girder is arranged at top, and driving, which can be only moved to, to be pulled beside force tester, then needs manpower by inspected lifting magnet equipment
Shift the centre of pulling-out force tester base onto.Moreover, also there are major safety risks in this process.Pulled if driving is close
During force tester, drop-in operation runaway condition, driving steel wire rope will encounter the spandrel girder pulled at the top of force tester, lead
Cause entirely pulls force tester and toppled over.
The content of the invention
The utility model provides the device that a kind of top-opening type detects magnetic force crane gear pulling-out force, can solve foregoing lack
Fall into.Foregoing gantry type frame structure pulls force tester, and test method is " drawing ".The utility model looks for another way, and uses
The mode on " top ", therefore named top-opening type.
Top-opening type refers to the mode for by force being separated absorbate with lifting magnet equipment magnetic work face with push rod.It is detected
Method is：Inspected lifting magnet equipment is placed on the platform of top-opening type pull-out force detector, makes lifting magnet equipment
In load state is inhaled, adsorb in the platform surface provided with many through holes.Push rod is equipped with each through hole of platform surface.With top
Bar departs from platform surface from the bottom up by lifting magnet equipment jack-up.Lifting magnet equipment departs from the top power of platform surface moment,
The as pulling-out force of lifting magnet equipment.This detection method is simple and convenient, safe and reliable.
The specific technical scheme of the utility model is：The platform surface of top-opening type pull-out force detector, is one piece thicker
Plane steel plate.There are many through holes on this block steel plate.A push rod is equipped with each through hole.Push rod can be by below it
Supporting plate is withstood.Pressure sensor and jack is arranged below in supporting plate.When the piston up-down of jack, so that it may so that supporting plate
Move up and down, so that push rod is extended or retracted in hole.When detecting the pulling-out force of magnetic force crane gear, by lifting magnet equipment
Place on steel plain, and in suction load state.The piston of jack is risen, by supporting plate jack-up, numerous push rods are also by with support
Plate rises.Then, lifting magnet equipment is pressed in those following push rod jack-up by controlling oneself, and departs from the surface inhaled.Read pressure
The data of sensor, are exactly the pulling-out force of lifting magnet equipment.
The embodiment of above-mentioned technical proposal, as top-opening type pull-out force detector.Its top is platform steel plate, and bottom is
Casing.Casing is made up of side plate, end plate, bottom plate and pin disk.Box house has gum.Gum by orifice plate, supporting plate, stiffener plate,
Push rod is constituted.It is pressure sensor below gum.It is hydraulic jack below pressure sensor.There is manual pump outside casing, show
Display screen.Manual pump is connected with hydraulic jack by pipeline.Display screen is connected with pressure sensor wire.
