Description
The utility model is about the hoisting crane windproof friction skidding device of rail-mounted crane particularly.
The main equipment that rail-mounted crane such as tower crane, span winch, transfer crane, gauntry crane, handling bridge, crane in bridge type etc. are worked in the open, because wind area is big, bearing bigger wind carries, for preventing that hoisting crane from being blown by strong wind, in the tail track overturning of being obstructed, all must the windproof friction skidding device of installing.
Existing windproof friction skidding device summarized in " the windproof friction skidding device of rail-mounted crane " literary composition (handling machinery third phase 9-14 in 1989 page or leaf).Skid-resistance requirements when satisfying mode of operation and starting easily at any time, its technical scheme all adopts clamp-type, promptly clamps the both sides at track top by a pair of clamp, stops the slip of hoisting crane by the friction force of generation.Because the size of friction force depends on the size of the gripping power (being positive pressure) that caliper unit produces, thereby the caliper unit size is big, secondly is when bearing external force, owing to easy vibration deformation loses clamping action.The reliability that also promising raising clamps and use manual self-locking rail clamping device, but open and close inconveniently, and carry out in working order the time.
The purpose of this utility model provides a kind of windproof friction skidding device of hoisting crane reliable, conveniently opening and closing that locks.
The purpose of this utility model reaches by following measure:
This windproof friction skidding device is made up of anchor pole, casing chute, anchor fluke mechanism and slide block, Breech block, cylinder lever connecting rod and lift system thereof.Lift system is a hydraulic push rod (18) (electrodynamic type or an electromagnetic type), and drive pulley (20), steel rope (17) make cylinder lever connecting rod (3) lifting (shown in Figure 3) with steel rope cutting ferrule (19).The bottom of anchor pole is the anchor point, the contact surface that itself and rail push up is a double inclined plane, the anchor pole upper end is a bolt shaft, the middle part of anchor pole is the anchor pole groove of a hollow, anchor pole is except that can be around anchor pole axis revolution, the end of bolt shaft and sliding sleeve (7) also can slide up and down in the passage of the casing chute of base seal, and casing (1) is fixed on middle part or two ends (shown in Figure 9) of hoisting crane cross sill.Anchor fluke mechanism comprises anchor fluke and coupling, the bottom of two anchor flukes contacts with two lower aerofoils on rail top, the bearing pin (16) of the outside portion of anchor fluke by coupling, connecting rod (9), bearing pin (13) link to each other with slide block in the anchor pole groove, the middle part of two anchor flukes is connected with the middle part of anchor pole respectively, and the groove that can hold Breech block is arranged at the top of anchor fluke.Breech block is in the anchor pole groove, and links to each other with the lower end of the cylinder lever connecting rod that passes bolt shaft and slide block middle part successively.
When hoisting crane carries under the effect when mobile at wind, the anchor point that contacts with rail surface can not move under the effect of friction force, and anchor pole is around the contact position S rotation of anchor point with rail surface, thereby make bolt shaft (5) around self rotating while of axis, also be displaced downwardly to sealing place of bottom, two lower aerofoils that inclined-plane in the sharp double inclined plane of anchor this moment and anchor fluke bottom tighten rail surface and tread respectively along the passage of casing chute (2).Because anchor pole rotated an angle (α), thus the contact position of the bottom of anchor point and anchor fluke and rail just not in same vertical surface, and the generation moment (shown in Figure 5) opposite with the turning over direction.It is big more that wind carries P, the angle of rotation (α) of anchor pole solderless wrapped connection synapsis is just big more, along with the vertical distance of anchor pole axis and rail item face more little (be among Fig. 5 and Fig. 6 h just big more), bolt shaft at casing along past more lower slider just in the passage of groove (2), and make the anchor point just big more to the pressure of tread face, thereby make the also corresponding increase of anti-tilting complex torque, force the wheel of hoisting crane to be pressed on the rail, prevent that effectively wheel breaks away from the overthrow accident that rail causes.
The anchor point also can make cambered surface with the contact surface shape on rail top, and h ' is corresponding with the slippage h in the whole chute for its pendulum spoke amount.
Rigidity connecting rod (9) in the coupling of anchor fluke outside portion also can be flexible steel rope or chain.
Anchor fluke middle part and anchor pole middle part also can be without the double-pin axle with single bearing pin link together (shown in Figure 7).
Centering rail when falling for ease of windproof friction skidding device, anchor fluke (11) bottom makes cambered surface (shown in Figure 8), and bigger gap (shown in Figure 1) is located to reserve at casing chute (2) in the both ends of bolt shaft (5).
The utility model compared with prior art has following advantage:
The first, owing to tighten two lower aerofoils of rail surface and tread simultaneously, thereby than depending merely on that side direction clamps generation and to be subject to the friction force antiskid that vibration deformation influences reliable.Especially when wind surface and locking face distance is very big (H among Fig. 9), this moment, K locking place was except that having along the thrust of track, also have upwards tilting moment, and make the very easy inefficacy of existing windproof friction skidding device, if use the utility model then this kind situation can not take place around opposite side L.
The second, do not rely on loading to obtain gripping power, so mechanism can be simple, compact, hydraulic push rod can adopt standardized component simultaneously, and these all make the maintenance of this device become convenient.Secondly, cylinder lever connecting rod and lift system also make anchor pole not fragile when self axis turns round for unsteady and non-rigid being connected.
Three, friction skidding device opens and closes very convenient and can carry out under crane operating status.Lift system is a normally closed mechanism, when hoisting crane travels and switch on, cylinder lever connecting rod is risen, so windproof friction skidding device is (being shown in Fig. 1 anchor fluke long and short dash line) of opening, and hoisting crane cylinder lever connecting rod when fixed-point operation and outage falls immediately, and makes device be in make position shown in Figure 1.But when hoisting crane did not have the tendency of moving, because anchor pole is vertical, the application force that anchor fluke, anchor point are produced by gravity was at same vertical surface, so do not produce the locking effect.And when the generation of slip is arranged, then can play clamping action as described earlier in this article at any time, therefore can allow hoisting crane safe operation and safety car in case of emergency under strong wind.
