Description
Technical field
The utility model belongs to elevator machinery field, is specifically related to the low constructure type anti-tilting apparatus of a kind of overhang crane.
Background technology
Overhang crane is all provided with the cantilever of certain length usually, and jib-length is generally determined according to the size of span.In practice, sometimes the needs of the operating range of hoist lifting hook are increased in order to meet user, lifting jib-length needs to increase, this may cause hoisting crane single wheel to bear wheel load, tumble, damage is caused to vibrative mechanism, when the jib-length of therefore traditional overhang crane needs to increase, except the stability of hoisting crane will be checked, also need to take anti-tipping measure.
What generally adopt in current technology application is arrange counterweight method and arrange energy disperser, but the shortcoming of two kinds of modes is also apparent; Counterweight method makes simply, cost is low, but can increase the deadweight of hoisting crane, and when the quality of counterweight is larger, volume is large; It is simple that buffer approach is set, but when after energy disperser and rail contact, the cart wheel of energy disperser side and track depart from, and cause the one-sided driving of hoisting crane, cannot normally run; Therefore be badly in need of a kind of anti-tilting apparatus meeting overhang crane, avoid again above problem simultaneously.The patent No. be 201420501944 Chinese utility model patent disclose a kind of overhang crane anti-tilting apparatus, comprise girder, wheel group and track, the main body of wheel group is by wallboard A, wallboard B, instead roll axletree, instead roll wheel, bearing, driven wheel, adhesion wheel and gear composition, adhesion wheel is connected with gear, gear and the anti-wheel that rolls engage, anti-distance of rolling between wheel and track bottom surface is 1 to 5 millimeter, utilize and instead roll the lower plane work of wheel at track, and control the height fall of rail joint well, ensure that the weld seam of the joint of lower plane should polish smooth, ensure that track lower plane is smooth.This overhang crane anti-tilting apparatus solves the problem that hoisting crane normally runs when wheel load born by cart wheel while anti-tipping, but it is only applicable to the overhang crane of coventional type structure, is not suitable for the overhang crane of low constructure type structure.
Utility model content
The purpose of this utility model is the above problem overcoming prior art existence, there is provided a kind of overhang crane low constructure type anti-tilting apparatus, be applicable to the overhang crane of low constructure type structure, hoisting crane can be realized while anti-tipping and normally run when wheel load born by cart wheel.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
The low constructure type anti-tilting apparatus of a kind of overhang crane, it comprises end carriage, wheel group and track, the main body of described wheel group rolls wheel by counter, bearing, instead roll axletree, anti-roller seat, adhesion wheel and gear combination form, described wheel group is connected with track, described end carriage is fixed with anti-roller seat by screw, adhesion wheel is provided with in described track, bottom surface is provided with the counter of hollow cylinder shape and rolls wheel, described counter rolling on the right side of wheel is provided with the shaft shoulder, the described anti-right side outward flange rolling wheel is provided with tooth, the described anti-axletree that rolls is through anti-center of rolling wheel, anti-axletree is rolled and counter rolling between wheel is provided with bearing described, describedly instead roll wheel and gears meshing, described gear is connected with driving wheel, arrange in orbit on the left of described adhesion wheel, be connected with gear on the right side of described driving wheel.
Further, described anti-distance of rolling between wheel end face and track bottom surface is 2 to 3 millimeters.
The beneficial effects of the utility model are:
The utility model anti-tilting apparatus has the advantage that is little, that be convenient to assembling that takes up room, be specially adapted to the overhang crane of low constructure type structure, by the operation scheme of anti-roller on track lower plane, while anti-tipping, achieve the normal operation of hoisting crane when wheel load born by cart wheel.
