Description
Technical field
The utility model relates to a kind of elevator machinery, particularly a kind of suspension hook of crane.
Background technology
In the prior art, crane mainly includes suspension hook, cable wire and corresponding hoisting mechanism, is provided with corresponding limit switch at a plurality of positions on some crane, when touching limit switch, and the action of crane fender guard; The crane that also has is provided with the mechanism of detecting the cable wire elongation, and when detecting the cable wire elongation above setting value, suspension hook then can not be mentioned, and plays the safety guard-safeguard effect; What also have is provided with overload protection on hoisting mechanism, when hoisting mechanism can not bear external tensile force and when reversing, send corresponding alarm, point out overweight; But these warning devices all design comparatively complicatedly, and cost is higher.
Existing suspension hook mainly includes rotating gib head, and gib head is connected rotationally with the carrying support, the carrying support is provided with pulley, will carry support by pulley and be suspended on the cable wire, and it is simple in structure, but function is single relatively, does not have the function of overload alarm.
The utility model content
The purpose of this utility model provides a kind of suspension hook with apparatus for warning overload, and suspension hook can be given the alarm when overload.
The purpose of this utility model is achieved in that a kind of suspension hook with apparatus for warning overload, comprise carrying support and rotating gib head, the carrying support is provided with pulley, the carrying support is suspended on the cable wire through pulley, described gib head upper end is connected rotationally with a load bearing seat, level is provided with loading plate in the carrying support, load bearing seat is arranged on the described loading plate, uprightly be provided with the spring of support bearing plate between loading plate downside and the carrying support, the loading plate below is provided with at least one pair of electrode, contain two electrode slices in every pair of electrode, one of them electrode slice is fixed on the carrying support, another electrode slice is fixed on the loading plate downside, and the two electrode slices series connection in the every pair of electrode inserts in the warning circuit.
During the utility model work, the gib head weight of slinging, the weight of object all acts on the spring through loading plate, the spring deformation in compression, two electrode slices distance in corresponding every group of electrode reduces, when the weight of heavy of lifting is excessive, and the contact of two electrode slices, the triggering warning circuit gives the alarm, and reminds the operating personal suspension hook to be in overload.Compared with prior art, the utility model is simple in structure, and is easily manufactured, and suspension hook can be given the alarm when overload.The utility model can be applied in the various places that need hoisting heavy, especially can use on tower crane for building.
Be protection electric elements and corresponding circuit, described electrode and corresponding warning circuit device top are provided with seal cover board.Seal cover board can stop that rainwater and dust enter, and avoids rainwater and dust to influence circuit working.
Above-mentioned electrode can be provided with two groups, and wherein one group of electrode array connects into an audible alarm circuit; Another group electrode array connects into a luminous warning circuit.Notice that by sound, light warning reminding operating personal suspension hook has been in overload.
For the handled easily personnel observe, the sounding of described audible alarm circuit and luminous warning circuit, luminous power element are separately positioned on carrying both sides, support top.
Be the convenient artificial alarming value of setting, be provided with chute in carrying support side upright, the electrode slice that fixes with the carrying support is arranged on the electrode bar, and the electrode bar wore long the screw retention of described chute on the carrying support.Unclamp screw, the electrode bar can slide along chute, change itself and on the same group in distance between another electrode slice, trigger stroke thereby changed two electrode slices, spring has the different distortion amount when circuit triggers, and the weight weight that can lift by crane on the corresponding gib head also changes.This structure makes the people artificially design alarming value, guarantees that suspension hook can be operated in the safe range.
