Abstract
The utility model discloses a medium and small sleeve drawing device for blast furnace iron making, comprising a set of manipulator assembly for hooking air ports of the medium and small sleeves, a hydraulic control system for providing power, and a rack for fixing to the hydraulic control system. The output of the hydraulic control system is divided into two parts, which are a main tension arm pulling out a piece and an auxiliary moment arm for automatically hooking the manipulator to the piece. Each set of the manipulator assembly comprises two manipulators which are symmetrically disposed side by side. The manipulator comprises an arm part and a hook part, and the hook part faces outwardly. The end portion of the arm part of the manipulator is provided with a rotation hole having a vertical axis, and the two manipulators are respectively coupled to a rotating shaft disposed on the main tension arm, and are respectively arranged at two sides of the auxiliary moment arm. The end part of the auxiliary moment arm is provided with two sets of movable connecting rods which move in a horizontal plane and are respectively and movably connected to the two manipulators. The medium and small sleeve drawing device for blast furnace iron making is advantageous in that no impact will occur; inner structures of the sleeves will not be damaged; labor and time are saved; productivity is improved.
Description
Technical field
The utility model discloses a kind of special equipment that is applied to blast furnace steel-making, be specially a kind of medium and small cover draw-off gear that is exclusively used in blast furnace ironmaking.
Background technology
In blast furnace steel-making, large cover connects the stove skin and entangles middle cover, and middle cover entangles little cover, and little cover send hot blast in blast furnace, and generally up to more than 1100 degree, middle cover generally is that cover cast iron, little generally all is copper to hot blast temperature, and adopts water-cooled.Of long duration, little cover is easily bad, is prone to accidents after leaking.Therefore, medium and small cover needs to change in use for some time.And medium and small being enclosed within the use procedure, little cover and middle cover separately are difficult between middle cover and the large cover, and usually the pulling capacity of 30-60 ton just can be with it disengagement.One of at present domestic mode of generally using is with the gas cutting cutting, but this way can only be discarded medium and small cover.Two of mode is to pass through specific purpose tool: its front end is the oral area that coupler body hooks medium and small cover; Cover has the weight that can slide on its handle, and the end of handle is for stopping projection.During use, manually coupler body is hooked middle or small looping first, then promote afterwards mutually weight with manpower, weight impinges upon and stops the upper active force that produces of projection; Shirk middle or small cover by continuous bump; The defective of this instrument is waste of manpower and time, usually to need to finish over 2 hours or 1 day shirking of medium and small cover; Secondly, powerful impact is easily destroyed the structure in the stove; And personal injury accident easily occurs.
Therefore the special equipment that designs the middle or small cover of dismounting in a kind of blast furnace steel-making is that relevant field has technical problem to be solved.
The utility model content
The utility model discloses the special equipment of the medium and small cover of dismounting in a kind of blast furnace steel-making, to solve the problems referred to above of prior art.
The purpose of this utility model can be achieved through the following technical solutions.
A kind of medium and small cover draw-off gear that is exclusively used in blast furnace ironmaking, it comprises:
The mechanical arm assembly that one cover hooks middle or small cover air port; One provides the hydraulic control system of power; And be fixed in frame on the hydraulic control system; Described hydraulic control system is output as two parts: the main pulling force arm that will be pulled out by draw piece and manipulator hooked automatically by the auxiliary arm of force of draw piece; Every cover mechanical arm assembly comprises two side by side symmetrical manipulators of placing, and manipulator is comprised of arm and hook portion, and its hook portion outwardly; The arm end of manipulator be provided with axis vertical turn the hole, two manipulators by turn the hole respectively with the rotating shaft socket that is arranged on the main pulling force arm; And be respectively in the both sides of the auxiliary arm of force; The end of the auxiliary arm of force is provided with two groups of movable rods mobile in horizontal plane, and is flexibly connected with two manipulators respectively.
Described main pulling force arm downside arranges a folding feet, so that balance.
Described mechanical arm assembly is two groups, respectively with middle cover and little cover coupling.
Be flexibly connected with pin member respectively between described movable rod, manipulator and the auxiliary arm of force, so that quick-replaceable machinery hand.
Described hydraulic control system is installed on the fork truck, is convenient to adjust height and mobile device.
The utlity model has following beneficial effect: 1, by quiet pulling force, finish the process of changing cover without the basis of impacting, do not damage the cover inner structure; 2, fully-automatic equipment saves manpower and time, and increases productivity, and improves worker's labour intensity; 3, guaranteed operating personnel's personal safety.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is plan structure schematic diagram of the present utility model;
Among the figure: 1, hydraulic control system 2, frame 3, main pulling force arm 4, the auxiliary arm of force 5, manipulator 6, movable rod 7, feet.
The specific embodiment
Further set forth technical characterstic of the present utility model below in conjunction with accompanying drawing and specific embodiment.
A kind of medium and small cover draw-off gear that is exclusively used in blast furnace ironmaking as depicted in figs. 1 and 2, it comprises:
The mechanical arm assembly that one cover hooks middle or small cover air port; One provides the hydraulic control system 1 of power; And be fixed in frame 2 on the hydraulic control system 1; Described hydraulic control system 1 is output as two parts: the main pulling force arm 3 that will be pulled out by draw piece and mechanical arm assembly hooked automatically by the auxiliary arm of force 4 of draw piece; Every cover mechanical arm assembly comprises two side by side symmetrical manipulators 5 of placing, and manipulator 5 is comprised of arm and hook portion, and its hook portion outwardly; The arm end of manipulator 5 be provided with axis vertical turn the hole, two manipulators 5 by turn the hole respectively with the rotating shaft socket that is arranged on the main pulling force arm 3; And be respectively in the both sides of the auxiliary arm of force 4; The end of the auxiliary arm of force 4 is provided with two groups of movable rods 6 mobile in horizontal plane, and is flexibly connected with two manipulators 5 respectively.
Described main pulling force arm 3 downsides arrange a folding feet 7, so that balance.
Described mechanical arm assembly is two groups, respectively with middle cover and little cover coupling.
