Abstract
The invention relates to a crane with an anti-deorbiting device, and the crane provided by the invention comprises an electric block, a driving trolley and a driven trolley, wherein the driving trolley and the driven trolley are fixedly connected with the electric block. The crane provided by the invention is characterized in that the outside of the driving trolley is provided with a protective hook assembly which is connected with the electric block; the protective hook assembly is composed of a protective hook body, a protective hook connecting frame and a fastening component; and the protective hook body and the protective hook connecting frame are respectively provided with an adjusting hole in the mutually-perpendicular directions of the protective hook body and the protective hook connecting frame. The crane with the anti-derailment device has the advantages that when the crane has abnormal cases (such as, a wheel assembly is deorbited, and the crane is skewed seriously), the protective hook body can be tightly blocked in an orbit, and then the effect of preventing the crane from deorbiting can be achieved, therefore, the application security of the crane can be improved, and under abnormal and accident conditions, the occurrence of vicious incidents such as crane deorbiting and dropping and the like can be impeded; and meanwhile, the personal safety of operating personnel can be guaranteed, and the situations of damaging conveyed articles and bringing unnecessary economic losses to users can be avoided.
Description
Technical field
The invention belongs to the crane facility technical field, particularly relate to a kind of hoisting crane with anti-derail unit.
Background technology
At present, in order to make hoisting crane, trolley crane particularly, the mode that horizontal wheel is installed is adopted in safe operation in orbit usually, guarantees that hoisting crane is by design track smooth running.Because the horizontal wheel axis in the known technology is vertical mutually with wheel axis, can only play the effect that prevents wheel gnawing rail, does not possess derailment-proof function.The limitation of existing structure: under special operation condition, unforeseen circumstances, the generation of malignant event such as cause that easily hoisting crane derails, falls.The so not only personal safety of entail dangers to operating personal, but also the article that can cause being transported sustain damage, and have brought unnecessary economic loss to the user.
Summary of the invention
The present invention provides a kind of hoisting crane with anti-derail unit of simple in structure, malignant event such as can prevent that hoisting crane from derailing under special circumstances, falling for solving the technical matters that exists in the known technology.
The technical scheme that the present invention takes for the technical matters that exists in the solution known technology is:
Hoisting crane with anti-derail unit, comprise electric block, with affixed active dolly and the driven dolly of electric block, it is characterized in that: the described active dolly outside is provided with and electric block bonded assembly anchor assembly, and described anchor assembly is to be made of anchor body, anchor link span and fastener.
The present invention can also adopt following technical scheme:
Have adjustment hole on described anchor body and the anchor link span mutually perpendicular direction.
Adjustment hole on described anchor body and the anchor link span mutually perpendicular direction is a slotted hole.
Advantage and good effect that the present invention has are: because the present invention adopts technique scheme, when abnormal condition appearred in hoisting crane, if wheel set de-orbits, serious deflection took place in hoisting crane, then the anchor body just can be tightly stuck with track, and then play the effect that prevents the hoisting crane derailing.So not only can improve the safety that hoisting crane uses, under special, unforeseen circumstances, can stop the hoisting crane generation of malignant event such as derail, fall.But also can guarantee the personal safety of operating personal, the article of avoiding being transported sustain damage and bring unnecessary economic loss to the user.

The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1-Fig. 5, have the hoisting crane of anti-derail unit, comprise electric block 1, active dolly 3 and the driven dolly 2 affixed with electric block 1, described active dolly 3 is made of actuating device 3-1 and wheel set 3-2.Be provided with and electric block 1 bonded assembly anchor assembly 4 in the described active dolly outside, described anchor assembly is to be made of anchor body 4-2, anchor link span 4-3 and fastener 4-1.Described anchor body 4-2 is two, and is installed in initiatively dolly 3 outsides by anchor link span 4-3 and fastener 4-1 symmetry.Have adjustment hole 4-4 on described anchor body and the anchor link span mutually perpendicular direction, in the present embodiment, the adjustment hole on described anchor body and the anchor link span mutually perpendicular direction is a slotted hole.
Described anchor body 4-2 should be according to the load-carrying capacity of electric block (hoisting crane), the unforeseen circumstances that may occur and the designing requirements of desiring to reach such as safety factor, its structure of appropriate design on the basis of accurate Calculation.Only provided a kind of simple structure in the present embodiment.
During installation, should guarantee to leave certain clearance 6 between anchor body and track 5 top flanges, the track side, to guarantee that when hoisting crane normally moves any interference does not take place for this anchor assembly and track.Adjustable ring gap 6 has slotted hole during for the ease of installation on anchor body 4-2 and anchor link span 4-3 mutually perpendicular direction, is convenient to adjust use.
Principle of work of the present invention:
When abnormal condition appearred in hoisting crane, if wheel set de-orbits, serious deflection took place in hoisting crane, just then anchor body 4-2 can be tightly stuck with track 5, and then played the effect that prevents the hoisting crane derailing.
