Abstract
The utility model discloses an anchoring device of a crane, which comprises a bracket, a screw shaft, an internally threaded sleeve and an anchoring seat, wherein the bracket is fixedly connected to the bottom of the supporting leg of the crane; the screw shaft is rotationally arranged on the bracket in such a manner that the screw shaft cannot move axially; the internally threaded sleeve is screwed on the screw shaft, and is arranged on the bracket in such a manner that the internally threaded sleeve can move axially but cannot rotate; and an anchoring hole matched with the outer surface of the internally threaded sleeve is formed in the anchoring seat. The anchoring device solves the problem that the conventional anchoring device of the crane is complex in structure, difficult to mount and dismount, troublesome to operate and inconvenient to use. The anchoring device has the advantages of simplicity in structure, convenience in mounting, dismounting and use, and the like.
Description
Technical field
The utility model relates to hoisting crane, particularly relates to the anchoring device of hoisting crane.
Background technology
The hoisting crane that is under the open-air atmosphere can receive the effect that wind carries, and is moving by wind under off working state for the hoisting crane that prevents open work in orbit, can use anchoring device usually.At present, the various anchoring device that is used for hoisting crane also exists many problems, like complex structure, installs, dismantles difficulty, and troublesome poeration uses inconvenience, and this has buried hidden danger for virtually the safe handling of hoisting crane.
The utility model content
The purpose of the utility model provides a kind of hoisting crane anchoring device, to solve existing hoisting crane anchoring device complex structure, installs, dismantles difficulty, troublesome poeration, awkward problem.
The purpose of the utility model realizes through following technical scheme:
A kind of hoisting crane anchoring device; Comprise support, screw shaft, inner screw sheath and anchor block; Said support is fixedly connected in hoisting crane supporting leg bottom, and said screw shaft turns but can not be arranged on the said support with moving axially, and said inner screw sheath screws on said screw shaft; And can move axially but be arranged on un-rotatably on the said support, offer the anchor hole that can cooperate on the said anchor block with said inner screw sheath outside face.
Preferably; Said screw shaft is arranged on the said support through bearing, bearing seat and roller bearing end cap; Said inner screw sheath is arranged on the said support through sheathed slip protecting sleeve on its outer surface, and the end that the non-and said inner screw sheath of said screw shaft screws is equipped with handwheel.
The beneficial effect of the utility model is: simple in structure, installation, dismounting and easy to use.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of the hoisting crane anchoring device of the utility model.
Fig. 2 is the installation site scheme drawing of the hoisting crane anchoring device of the utility model.
Among the figure: 1, support; 2, screw shaft; 3, inner screw sheath; 4, anchor block; 5, bearing seat; 6, slip protecting sleeve; 7, handwheel; 8, hoisting crane supporting leg.
The specific embodiment
As shown in Figure 1; The hoisting crane anchoring device of the utility model comprises support 1, screw shaft 2, inner screw sheath 3 and anchor block 4, and said support 1 is fixedly connected in hoisting crane supporting leg bottom; Said screw shaft 2 turns but can not be arranged on the said support 1 with moving axially; Said inner screw sheath 3 screws on said screw shaft 2, and can move axially but be arranged on un-rotatably on the said support 1, offers the anchor hole that can cooperate with said inner screw sheath 3 outside faces on the said anchor block 4.
Preferably; Said screw shaft 2 is arranged on the said support 1 through bearing, bearing seat 5 and roller bearing end cap; Said inner screw sheath 3 is arranged on the said support 1 through sheathed slip protecting sleeve 6 on its outer surface, and the end that said screw shaft 2 non-and said inner screw sheaths 3 screw is equipped with handwheel 7.
The method of application of the utility model is: with the adapter plate of support 1 adapter plate and hoisting crane supporting leg 8 bottoms through its top with Bolt Connection together; The a certain position that anchor block 4 is fixed on the ground; When hoisting crane needs anchoring, only need to move to anchorage 4 places to hoisting crane, rotate the handwheel 7 that is arranged on screw shaft 2 one ends then; Inner screw sheath 3 just can advance and get into the anchor hole of offering on the anchor block 4 that can cooperate with said inner screw sheath outside face, thereby realizes the anchoring of hoisting crane; When needs are removed anchoring, only need the backward rotation handwheel, inner screw sheath 3 is cooperated with anchor hole disengaging on the anchor block 4 get final product.
The utility model is simple in structure, and installation, dismounting and easy to use have solved existing hoisting crane anchoring device complex structure, installs, dismantles difficulty, troublesome poeration, awkward problem.
