Abstract
The invention relates to a pair of synchronous anti-slip balanced lifting clamp forceps. The synchronous anti-slip balanced lifting clamp forceps comprise a lifting beam, a lifting hole, a balance shaft beam I, stop nuts, connecting rods I, connecting rods II, studs, front clamps, rear clamps, rubber pads, a balance shaft beam II and a synchronizing bridge shaft. When the synchronous anti-slip balanced lifting clamp forceps are tried, a lifting hook of a lifting device passes through the lifting hole, a force bearing point of an arch center of the lifting hole is just in contact with the lifting hook, and the borne acting force is radiated to each point on the bottom side of the arched lifting beam through the lifting hole, so that the uniform stressing is guaranteed; the lengths of the balance shaft beam I and the balance shaft beam II are accordant, so that the horizontal balance of objects during the lifting is guaranteed; by virtue of the rubber pads arranged in working regions of clamps of forceps heads, the friction force is increased, a procedure for using a steel wire rope is omitted, and the probability that the objects fall when being lifted is reduced; by virtue of the synchronizing bridge shaft welded to the front clamps, the frequent operation time of workers caused due to the asynchronization of the front clamps and the rear clamps is shortened when the objects are lifted up or down.
Description
Technical field
The present invention relates to lifting device field, be specifically related to a kind of synchronously anti-skidding balance crane clamping pincers.
Background technology
In the production facilities of the industries such as building materials, metallurgy, electric power, petrochemical complex, machinework, frequent use lifting device, when to the lifting of comparatively long-object, steel rope and lockset shackle is generally all used to bundle lifting workpiece, if because of misoperation, when lifting object lack of equilibrium, center of gravity, very easily come off in hoisting process, cause safety misadventure to occur.
Summary of the invention
The object of the present invention is to provide a kind of synchronously anti-skidding balance crane clamping to clamp, when lifting object, stress point can be expanded, ensure stress balance.Function is firmly grasped in the adhesion strengthening binding clip operating area, and can keep the horizontal equilibrium of hoist article, and when preventing from lifting object, object emphasis is unbalance, the safety misadventure caused.
For achieving the above object, present invention employs such technical scheme: a kind of synchronously anti-skidding balance crane clamping pincers, by hanging beam, lifting hole(eyelet), balance bloster one, black nut, pipe link one, pipe link two, thru-bolt, fore-clamp, rear folder, rubber pad, balance bloster two, form with fore-and-aft gangway axle; It is characterized in that, hanging beam profile is isosceles trapezoid, arch lifting hole(eyelet) is offered at the center of hanging beam, lifting hole(eyelet) arch arc quadrantal points is positioned at this synchronously anti-skidding balance crane clamping and clamps integrally-built line of centers, hanging beam base is welded on balance bloster one, balance bloster one or two end car has a head, the hole that the silk head of balance bloster one or two end is offered through pipe link one and pipe link two one end, then with black nut be fastened on through silk head on; The hole thru-bolt series connection that pipe link one other end at two ends is offered is pressed from both sides afterwards, and fastening by fastening for thru-bolt two ends with black nut; The hole thru-bolt that pipe link two other end at two ends is offered is connected fore-clamp, and fastening by fastening for thru-bolt two ends with black nut; The fore-clamp of two ends pipe link one, pipe link two series connection, rear folder intersection do tong-like, and offer hole at the point of crossing of fore-clamp, rear folder, run through with the silk head of balance bloster two two ends car and penetrate two ends fore-clamp, the point of crossing of rear folder offers hole, then with the position that black nut fastening balance bloster two two ends penetrate; Wherein the bottom of fore-clamp, rear folder is arcuation, and fore-clamp, force area, rear folder bottom rubber pad wrap up, and on the inwall in this arcuation region, fore-clamp bottom, center welding is with fore-and-aft gangway axle, by the fore-clamp level connection joint at two ends; Each is joined needs to use the fastening place of black nut as accessory, needs the reserved working clearance, ensures that each joins that to do between accessory flexible.
After adopting such structure, when this synchronously anti-skidding balance crane clamping pincers on probation, the suspension hook of weight-lifting equipment is through lifting hole(eyelet), and the arch arc center stressed point of lifting hole(eyelet) just contacts with suspension hook, by lifting hole(eyelet), the application force be subject to is radiated to each point of base of arch hanging beam, ensure that stress equalization.Two upper and lower equalizing bar length are consistent, ensure that the horizontal equilibrium of object during lifting.The built-in rubber pad in binding clip clip work area enhances friction force, decreases the operation using steel rope, the probability that when reducing lifting object, object comes off.When the same fore-and-aft gangway axle of fore-clamp welding makes lifting or puts down object, decrease the time of the workman's frequent operation caused because two ends clamp is asynchronous.This synchronously anti-skidding balance crane clamping pincers, in process on probation, totally decrease the frequent operation of staff, ensure that the balance transport of hoist article, greatly reduce because object breaks off relations the safety misadventure caused.
Accompanying drawing explanation
Shown in accompanying drawing be the present invention synchronously anti-skidding balance crane clamping pincers perspective view.
