Abstract
The utility model relates to a rotary anchoring device of a portal crane, which comprises an anchor pin, an anchor block and an anchor frame, and is characterized in the inclusion of a rotary table, a cylindrical flange, an independent operating box, a hook and a chain, wherein the independent operating box is fixed on a cylinder body, the cylindrical flange is arranged on the cylinder body, and the anchor frame is welded to the bottom of the rotary table; the anchor block is welded onto the cylindrical flange; a gap is reserved between the anchor frame and the anchor block, and the anchor pin is arranged on the hook; and the anchor pin is inserted into an anchor block hole, one end of the chain is fixed on the anchor frame, while the other end of the chain is fixed on the anchor pin. A limit switch is arranged on the anchor frame. The rotary anchoring device of the portal crane has simple and reasonable structure, and can reasonably solve the problems of the prior art that the operation is inconvenient and the working efficiency is low.
Description
Technical field
The utility model belongs to technical field of engineering machinery, relates to a kind of improvement of handling equipment, specifically is a kind of span winch rotation anchoring device.
Background technology
The rotation anchoring device of span winch is a kind of windproof safety device that prevents typhoon.Hoisting crane should in order to avoid typhoon comes the rotating part of interim span winch to rotate freely, be guaranteed the safe handling of hoisting crane with the rotating part grappling of span winch under off working state, avoid the generation of safety misadventure.Rotation anchoring device and Spin Control interlocking, the grappling state shows in the operation driver's cab.The operation of rotation anchoring device generally needs two people to cooperate: one at driver's cab inner control rotative speed and hand of rotation, another one is observed the operating personal in rotation grappling present position and the timely notice driver's cab outside driver's cab, operating personal in the driver's cab is operated according to outdoor personnel's password, after treating that grappling rotates to assigned address, anchor pin is inserted in the anchor block hole by outdoor personnel.The operation of this rotation anchoring device is very inconvenient, inefficiency.
Summary of the invention
The purpose of this utility model is at above shortcomings in the prior art, provide a kind of can simple and ingenious structure, span winch rotation anchoring device safe and reliable to operation, this rotation anchoring device can effectively overcome unhandy problem, improves the work efficiency of operating personal.
The technical scheme that provides according to the utility model: a kind of span winch rotation anchoring device comprises anchor pin, anchor block, anchor frame, feature is: also comprise turntable, cylinder flange, independent operation case, hook, chain, described independent operation case is fixed on the cylinder, the cylinder flange is arranged on the cylinder, is welded with anchor frame in the bottom of described turntable; On described cylinder flange, be welded with anchor block; Be provided with the gap between anchor frame and the anchor block, anchor pin is arranged on the hook; Anchor pin is inserted in the anchor block hole, and chain one end is fixed on the anchor frame, and the other end is fixed in the anchor pin.Described anchor frame is provided with limit switch.
The utility model is simple and reasonable, can rationally solve rotation anchoring device inconvenient operation, ineffective problem.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A place enlarged drawing among Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As Fig. 1～shown in Figure 2, comprise anchor frame 1, hook 2, chain 3, limit switch 4, anchor pin 5, anchor block 6, cylinder flange 7, turntable 8, pivoting support 9 and independent operation case 10.
The utility model adopts at described turntable 8(rotating part) the bottom be welded with anchor frame 1; Described independent operation case 10 is fixed on the cylinder, and cylinder flange 7 is arranged on the cylinder, and (non-rotating part) is welded with anchor block 6 on described cylinder flange 7; Be provided with the gap between anchor frame 1 and the anchor block 6, anchor pin 5 is arranged on the hook 2; Anchor pin 5 is inserted in anchor block 6 holes, and chain 3 one ends are fixed on the anchor frame 1,
The other end is fixed in the anchor pin 5.Described anchor block 6 bore dias suitably strengthen than anchor pin 5 diameter dimensions, are convenient to the centering operation.Described anchor frame 1 is provided with limit switch 4.
Under the utility model rotating mechanism mode of operation, the inner ring that rotating mechanism drives turntable 8 and pivoting support 9 rotates (outer ring of pivoting support 9 and cylinder flange 7 maintain static) together, by control rotative speed of the operating handle in the driver's cab and direction, anchor pin 5 this moment places on the hook 2; During off working state, by the 10 control rotating mechanisms of the independent operation case on the cylinder, treat that anchoring device rotates to assigned address, after the hole centering of anchor frame 1 and anchor block 6, anchor pin 5 is inserted in anchor block 6 holes, anchor pin 5 this moment makes 4 actions of rotary stopper switch, and rotating mechanism can't start, and the complete machine turntable is in the grappling state with top (rotating part).Anchor frame 1 only needs a people to stand on the platform with the centering in anchor block 6 holes, and is by 10 controls of the independent operation case on the cylinder, easy to operate, quick.
