The specific embodiment
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the utility model can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Figure 3, the anchoring device that the utility model specific embodiment proposes is provided with grappling gear 3, transmission shaft 4, locking component 7 and drive element 6, for the structure and the principle of work that clearly demonstrate this anchoring device are set forth below in conjunction with hoisting crane.
Hoisting crane is provided with turn table 5, driven wheel (not shown), swiveling gear 2 and pedestal 1 conventionally, swiveling gear 2 is fixedly installed on pedestal 1, driven wheel and turn table 5 are rotatably connected, driven wheel engages with swiveling gear 2, when driven wheel rotates, can order about turn table 5 (the namely center of swiveling gear 2) rotation around pedestal 1 center; The concrete set-up mode of above-mentioned anchoring device on hoisting crane is: as shown in Figure 1, drive element 6 is fixedly installed on turn table 5 by connecting panel 8, transmission shaft 4 is arranged on turn table 5 rotationally by connecting panel 8, transmission shaft 4 bottoms are coaxially connected with grappling gear 3, transmission shaft 4 tops are provided with male splines, and grappling gear 3 engages with swiveling gear 2, on locking component 7, are provided with male splines, under the ordering about of drive element 6, locking component 7 can move up and down; When hoisting crane normal operation, locking component 7 is in the unlocked position, and driven wheel orders about turn table 5 and rotates, under the drive of turn table 5, grappling gear 3 occurs around the center of swiveling gear 2 " revolution ", and the gear 3 of grappling is simultaneously also around transmission shaft 4 centers " rotation "; When needs grappling hoisting crane (namely locked turn table 5), drive element 6 orders about locking component 7 and moves downward, and then the female splines on locking component 7 is coordinated with the male splines on transmission shaft 4, under the effect of locking component 7, grappling gear 3 cannot " rotation ", and then also cannot realize " revolution ", thus limit the relative position of turn table 5 and pedestal 1, finally realize grappling; Completing after predetermined maintenance or maintenance operation, can locking component 7 upwards be promoted by drive element 6, and then make locking component 7 depart from and coordinate with transmission shaft 4, thereby realize release.
In embodiment further, in order to make locking component 7 and coordinating of transmission shaft 4 can adapt to certain manufacturing and fixing error, by hinged to locking component 7 and drive element 6, and jointed shaft 9 between locking component 7 and drive element 6 is vertical with transmission shaft 4; Like this, locking component 7 can be realized beat among a small circle, as because installing or when manufacturing errors causes transmission shaft 4 with locking component 7 disalignment, locking component 7 can adapt to transmission shaft 4 by small beat.For preventing that locking component 7 from deflection on a large scale occurring under external force, limit base 10 can be set on turn table 5, waist shaped hole 11 is set on limit base 10, and the bottom of locking component 7 is arranged in waist shaped hole 11, beat in the scope that locking component 7 can only limit at waist shaped hole 11 like this.In addition, the outline of locking component 7 can be arranged to waist shaped hole 11 match form, make locking component 7 be stuck in the direction that can only limit along waist shaped hole 11 in waist shaped hole 11 and move but can not rotate, when grappling, limit base 10 can bear the torque that locking component 7 transmits.
Certainly, the structure that realizes locking transmission shaft 4 is not limited in above-mentioned form, can also pass through detent configuration; The pin-and-hole that specifically can be provided with horizontal direction on transmission shaft 4, locking component 7 is bearing pin, and drive element 6 is connected with bearing pin, and when grappling, drive element 6 orders about bearing pin and inserts in pin-and-hole, and while removing grappling, drive element 6 is extracted bearing pin in pin-and-hole.
In the above-described embodiments, drive element 6 can be that electric pushrod or hydraulic push rod are such as hydraulic ram, as long as it can order about locking component 7 and complete predetermined action.
In the above-described embodiments, controller can also be set on hoisting crane, operating personal can be controlled the action that drive element 6 carries out grappling or removes grappling easily by controller.
In view of grappling gear 3 can carry out around the center of swiveling gear 2 360 degree rotations not, when being necessary, anchoring device can be at any one angle locking turn table 5, and then realizes grappling.
In addition, the utility model specific embodiment also proposes a kind of hoisting crane with above-mentioned anchoring device; Compared with prior art, by above-mentioned anchoring device is set, this hoisting crane can carry out grappling at an arbitrary position.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
