Abstract
The utility model relates to a rotary arm positioning mechanism of an inner liner disintegrate machine for a metal-mixing trolley, comprising a big arm and a small are of a rotary arm, wherein, the front end of the large arm is provided with a pin with a return spring, the pin is glidingly matched with a positioning hole on a rotary disk which is used for connecting the big and the small arms, and the pin is synergically controlled by a pin automatic control mechanism and a small rotary hydraulic system. The pin automatic control mechanism is a hydraulic control mechanism, or a pneumatic control mechanism, or an electric control mechanism. The rotation of the small arm and the positioning of the pin can be operated by a person, and the utility model has the advantages of easy use, and labour saving.
Description
The utility model relates to a kind of locating mechanism that is used for the pivoted arm locating mechanism, particularly a kind of automatic control of inner liner of hot iron mixer disintegrating machine.
Metal mixer car is the visual plant that in the modernized iron and steel enterprise molten iron is transported to steel melting furnace by blast furnace.It is the hot metal ladle of a fusiformis, and the mouth of a perfusion molten iron is arranged in the middle.After it used certain number of times, at this moment refractory lining material require transposing wherein just needed to use disintegrating machine, and its pivoted arm stretches into metal mixer car inside, and its old liner fragmentation is disposed.Disintegrating machine is a caterpillar walking machine, at the front end of its pivoted arm hydraulic pressure or pneumatic quartering hammer is housed.Its pivoted arm is made of big forearm, and forearm can left rotation and right rotation, when rotating to suitable working position, inserts with latch in the pilot hole of the rotating disk that connects big forearm, makes it fixingly carry out work then.
Existing disintegrating machine, pulling out by manpower of above-mentioned latch undertaken by pull bar or cable wire.Require a people to control the rotation contraposition of forearm during operation, another person spurs latch, very inconvenient and effort.
The pivoted arm locating mechanism that provides a kind of inner liner of hot iron mixer disintegrating machine to use is provided the purpose of this utility model, can locate automatically during the forearm rotation, and is easy to operate, laborsaving.
For achieving the above object, the utility model adopts following technical proposals: the same big arm and the forearm that includes pivoted arm with prior art of this inner liner of hot iron mixer disintegrating machine pivoted arm locating mechanism, big arm front end have the latch of band return spring to join with the pilot hole cunning on being connected big forearm rotating disk.It is characterized in that: latch is by the hydraulic efficiency system Collaborative Control of a latch automatic controls and forearm rotation.
Above-mentioned latch automatic controls can be a hydraulic control, also can be pneumatic control mechanism, can also be electric control mechanism.
If the latch automatic controls is a hydraulic control, its structure can be designed as: a synchronous two position three way directional control valve of electromagnetic direction valve with forearm rotating hydraulic system is arranged, this reversing valve control fuel tank and high pressure fuel source lead to the oil circuit of an oil cylinder, and the piston of band return spring drives latch by connecting rod in the oil cylinder.
If the latch automatic controls is the air pressure controlling organization, its structure can be designed as: a synchronous pneumatic control valve of electromagnetic direction valve with forearm rotating hydraulic system is arranged, this Hysteresis for Pneumatic Control Valves source of the gas leads to the gas circuit of cylinder, and the piston in the cylinder drives latch by connecting rod.
If the latch automatic controls is an electric control mechanism, its structure can be designed as: an electric motor is controlled the electromagnetic direction valve run-in synchronism of this electric motor and forearm rotating hydraulic system by gear or pulley gear control latch by electrical system.
The utility model compared with prior art, has conspicuous following advantage: because latch is by the hydraulic efficiency system Collaborative Control of a latch automatic controls and forearm rotation, can operate rotation of control forearm and latch location by a people, easy to operate, laborsaving.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the bulk shape diagrammatic sketch that adopts inner liner of hot iron mixer disintegrating machine of the present utility model.
Fig. 2 is the bulk shape diagrammatic sketch that adopts inner liner of hot iron mixer disintegrating machine of the present utility model.
Fig. 3 is the vertical view of " A " portion among Fig. 2.
An optimum implementation of the present utility model is: referring to Fig. 1, Fig. 2 and Fig. 3.This inner liner of hot iron mixer disintegrating machine pivoted arm locating mechanism includes the big arm 9 and the forearm 12 of pivoted arm, and big arm 9 front ends have 11 sliding the joining of pilot hole on the latch 8 of being with return spring 7 and the rotating disk 10 that is connected big forearm 9,12.Referring to Fig. 2, the bottom of latch 8 connects a latch automatic controls 13 that is fixed in big arm 9 belows.Referring to Fig. 1, latch automatic controls 13 is a hydraulic control, its structure is: fix an oil cylinder 5 below big arm 9, a piston 4 is arranged in the oil cylinder 5, the right-hand member of piston 4 is by spring 3 supportings, piston 4 left ends connect a piston rod that stretches out oil cylinder 5, the piston rod outer end is hinged by an end of a pin and a square connecting rod 6, place, right angle, square connecting rod 6 middle part is hinged with the bearing that is fixed on below the big arm 9 by pin, and square connecting rod 6 the other ends are hinged by the bottom of pin and latch 8; The left chamber of oil cylinder 5 is by the controlled oil out port of a two position three-way valve 2 of pipeline connection, and two interfaces in addition of two position three-way valve 2 are connected high pressure fuel source and fuel tank 1 respectively.Its principle of work is: when forearm 12 will rotate, reversing valve 2 action earlier made pressure oil enter in the oil cylinder 5 through reversing valve 2, and oil cylinder inner carrier 4 moves to right, and by piston rod and connecting rod 6 pulling latches 8, latch 8 shifts out from the pilot hole 11 of rotating disk 10; When forearm 12 forwarded new position, hole to, reversing valve 2 resetted, and the oil in the oil cylinder 5 flows to fuel tank 1, and to moving to left, then latch 8 upwards moves under return spring 7 effect and inserts in another pilot hole 11 on the rotating disk 10 piston 4 under the effect of return spring 3.
