Description
Technical field
This utility model relates to inspection trolley technical field, is specially a kind of blast furnace chute inspection trolley.
Background technology
At present, during blast furnace ironmaking, needing every half a year to overhaul blast furnace chute, but old blast furnace maintenance space is narrow, and without crane gear walking tracks such as common dolly or calabashs, the mobile crane such as automobile cannot be introduced into again working site, it is impossible to meets duty requirements.Chute maintenance is transported by manpower completely, wastes time and energy, and efficiency is the lowest, dangerous factor, and the cost of overhaul is high.
Utility model content
The purpose of this utility model is to provide a kind of blast furnace chute inspection trolley, simple in construction, and time saving and energy saving, efficiency is the highest, and safety factors is high, and the cost of overhaul is low, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of blast furnace chute inspection trolley, including trolley frame, the both sides of described trolley frame are mounted on walker, the bottom of described walker is connected with the slip castor of walker inner chamber by worm and gear motor, the both sides of walker are equipped with the firm track of H type, the top of described trolley frame is provided with lifting mechanism, and lifting mechanism is by double crosslinking drum special steel wire rope electric hoist, lifting motor and electric controller composition, described double crosslinking drum special steel wire rope electric hoist passes through messenger wire and directive wheel, fixed pulley and suspension hook connect.
Preferably, described trolley frame is centrosymmetric about fixed pulley.
Preferably, described electric controller is electrically connected with walker and lifting mechanism respectively.
Preferably, described messenger wire is standard steel wire rope.
nullCompared with prior art，The beneficial effects of the utility model are: this blast furnace chute inspection trolley，Simple in construction，Easy to use，Utilize H profile steel track，I.e. can meet cantilever carrying article demand，Again can be with vertical lifting，Overall operation is stable，The cost of overhaul can be effectively reduced in the case of ensureing safety，Be ensure that the requirement of vertical lifting by double crosslinking drum special steel wire rope electric hoist simultaneously，Narrow space requirement and head room requirement is met by cantilever directive wheel，By directive wheel externally-hanging type load-engaging device，Increase working space，Trolley travelling track is H profile steel bottom wing listrium upper surface simultaneously，Decrease the demand of spatial altitude，Increase job area，The design of double crosslinking drum special steel wire rope electric hoist simultaneously，Avoid rocking and displacement in work process，More convenient to use，It is suitable for promoting the use of.
Accompanying drawing explanation
Fig. 1 is this utility model front schematic view；
Fig. 2 is this utility model schematic top plan view.
In figure: 1 trolley frame, 2 fixed pulleys, 3 suspension hooks, 4 directive wheels, 5 walkers, 6 H profile steel tracks, 7 double crosslinking drum special steel wire rope electric hoists, 8 lifting motors, 9 worm and gear motors, 10 messenger wires, 11 slip castors, 12 electric controllers.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1-2, a kind of technical scheme of this utility model offer: a kind of blast furnace chute inspection trolley, including trolley frame 1, the both sides of trolley frame 1 are mounted on walker 5, the bottom of walker 5 is connected with the slip castor 11 of walker 5 inner chamber by worm and gear motor 9, the both sides of walker 5 are equipped with the firm track of H type 6, the top of trolley frame 1 is provided with lifting mechanism, and lifting mechanism is by double crosslinking drum special steel wire rope electric hoist 7, lifting motor 8 and electric controller 12 form, double crosslinking drum special steel wire rope electric hoist 7 is by messenger wire 10 and directive wheel 4, fixed pulley 2 and suspension hook 3 connect.
This blast furnace chute inspection trolley, simple in construction, easy to use, utilize H profile steel track 6, i.e. can meet cantilever carrying article demand, again can be with vertical lifting, overall operation is stable, the cost of overhaul can be effectively reduced in the case of ensureing safety, be ensure that the requirement of vertical lifting by double crosslinking drum special steel wire rope electric hoist 7 simultaneously, narrow space requirement and head room requirement is met by cantilever directive wheel 4, by directive wheel 4 externally-hanging type load-engaging device, increase working space, trolley travelling track is H profile steel bottom wing listrium upper surface simultaneously, decrease the demand of spatial altitude, increase job area, the design of double crosslinking drum special steel wire rope electric hoist 7 simultaneously, avoid rocking and displacement in work process, more convenient to use, it is suitable for promoting the use of.
Trolley frame 1 is centrosymmetric about fixed pulley 2, and centrosymmetry makes trolley frame 1 more stable, it is simple to the lifting of trolley frame 1 and use.
Electric controller 12 is electrically connected with walker 5 and lifting mechanism respectively, it is simple to electric controller 12 is for the control of single unit system, and messenger wire 10 is standard steel wire rope, and the crane capacity making messenger wire 10 is higher.
Operation principle: during use, first trolley frame 1 is fixed, then walker 5 is driven to move at H profile steel bottom wing listrium upper surface by electric controller 12, then control double crosslinking drum special steel wire rope electric hoist 7 by electric controller 12 and lifting motor 8 drives directive wheel 4 and fixed pulley 2 by messenger wire 10, thus drive suspension hook 3 hoist and land, embodiment the most of the present utility model, for the ordinary skill in the art, it is appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, amendment, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
