Description

Stove pounding machine

The utility model relates to a kind of casthouse equipment of ferroalloy smelting--furnace charge stirrer.

Furnace charge stirrer is mainly used in smashing, choose and piling up of furnace charge in the smelting process, its objective is that the ventilative property that increases furnace charge smelts efficient to improve.This equipment is the indispensable tool of production in the ferroalloy smelting process.At present, it is mechanically operated structure that furnace charge stirrer adopted more, because of its driving-chain is long, kinematic pair wearing and tearing big, spacing wayward or fragile and part, a motor etc. when transfiniting, also big because of consumable accessory replacing amount, expense is high, the workman handles and safeguards that labour intensity is big etc., brings unfavorable factor to production.

The purpose of this utility model is that a kind of mechanical handling that changes of design is hydraulic operated furnace charge stirrer.

Present design is to get on to abandon its mechanical handling partly to install the hydraulic system that a cover is made of motor, oil pump, oil cylinder, control valve and oil circuit etc. on mechanical type furnace charge stirrer basis.Because of this system adopts the oil circuit that is made of through the routine design commercial standard type and universal Hydraulic Elements,, the utility model constitutes so describing the structure of this machine emphatically.For realize the smashing of furnace charge, choose, accumulation etc., its machine should be able to finish advance one retreat, the flexible and course of action up and down of stamp stem.For this reason, this machine mainly contains with the lower part and forms;

(1), the flexible and luffing mechanism of stamp stem.Stamp stem is an elongated metallic rod, comprises the bar head and the bar of twisting the end be connected on bar, and the other end of stamp stem and an oil cylinder join, and when oil cylinder is worked, stamp stem is stretched out or withdraws.Swinging up and down of stamp stem is that flexible work by another oil cylinder is finished, and concrete structure is as follows.The stamp stem device on the support that is fixed with the support that contains directive wheel and channled rail and therein.The support that contains a pair of directive wheel places a termination of support, and another places the support stage casing approximately, respectively is shaped on diaxon to place a pair of directive wheel that can guarantee the stamp stem easy motion during two plate shapes are supported.The other end of stamp stem connects the joint of two directive wheels that join with an oil cylinder connecting rod and be shaped on, and this two directive wheel places and is fixed on the support termination in the two parallel channled rails, and each makes a △ bearing admittedly with the articulated mounting oil cylinder parallel with guide rail two guide rails, one end.Its connecting rod is stretched when oil cylinder is worked, contracting drives stamp stem through joint and advance or move back, to finish the action that furnace charge is smash.Aforesaid support be its cross section be do not wait rectangle and end face be plane and the bottom surface is the plate frame structure of folding face, the protuberance of frame bottom folding face is shaped in the bearing of a pair of bearing of shaft device on being fixed in a base, forming support and above structure thereof can be around the rotation of this point, and base is shaped on and places rotatable wheel of two channled rails that is fixed on the chassis.Also make the bearing of hinged two operating cylinders simultaneously on the base admittedly, wherein the bottom of an oil cylinder is connected to this seat, and certain is a bit on aforementioned brackets for the rod hinge connection of oil cylinder.When oil cylinder was worked, the moment that the stretching, contract of its connecting rod produces can make support center on aforesaid fulcrum and rotate, even also stamp stem has been realized swinging up and down--and choose and pile up action.

(2), the driving and reversing mechanism of stamp stem.For adapting to large diameter smelting furnace and make furnace charge stirrer be unlikely too huge, the mechanism that adopts stamp stem to advance and retreat.As mentioned above, be fixed on two parallel channled rails on the chassis and be to be used for making and be located in the track that the support that includes stamp stem on the base moves forward and backward, and the power of its advance and retreat is articulated in the cross cylinder that is fixed on the bearing on the base from its connecting-rod head, this cylinder apparatus is at the bearing that is fixed on the chassis, when oil cylinder was worked, the part (comprising stamp stem) that drives more than the base of stretching, contract of its connecting rod moved forward and backward along channled rail.

(3), the walking mechanism of body.For not operating for fear of other technology in the smelting process, furnace charge stirrer should be stepped back to the safe place this moment, and also promptly this machine should have a mechanism of walking automatically--comprise walking oil cylinder, tooth bar, gear, wheel and car body etc.Car body is to be welded into the device furnace charge stirrer by channel-section steel and steel plate etc., be shaped on two pairs of wheels that can on rail, roll under its body, wherein be equipped with gear on the wheel shaft with the coaxial gears engaged of an idler gear, idler gear is meshed with the tooth bar that an oil cylinder connecting rod joins, and oil cylinder is other to be placed car body one side and be articulated in the bearing that is fixed on the car body.When oil cylinder work makes connecting rod one tooth bar when motion, rotate each gear and wheel is rolled on rail and then drive furnace charge stirrer and advance and one retreat.

(4), mainly form about the rotating part of body by rotating disk, axis, support wheel etc.Rotating disk is that its periphery is shaped on the steel-casting of groove and is installed with on car body, the back side, aforesaid chassis is shaped on the support wheel that can roll in the rotating disk border groove, do to live with axis with rotating disk and be connected in the chassis, when needs, can manually promote rotating disk and do 90 ° with interior rotation, do to make things convenient for other technology groove with top.

(5), hydraulic control system and operation.As previously mentioned, this system adopts the conventional design of hydraulic technique, is the cardiac component of furnace charge stirrer, and it is controlled each oil cylinder and finishes desired action.Wherein, for finishing choosing and pile up and need swinging up and down outside oil cylinder and the cross cylinder teamwork of furnace charge, other oil cylinder is a single action.The reversal valve of oil cylinder adopts hand-operated direction valve, all is loaded in the control cabinl pulpit of side burr on the chassis.Overflow valve in the system can effectively be controlled its operating pressure and protective effect has been played in the overload of executive component.

The furnace charge stirrer that the utility model is designed, because of adopting hydraulic control system, under the prerequisite of finishing and be mechanically operated by the identical functions action, these facility have reliable operation, safety, compact conformation, weight of equipment is little, materials are few, cost is low, the characteristics of energy-conservation and easy manipulation.Be the comparatively advanced practical equipment of a kind of ferroalloy smelting.

For implementing above-mentioned design, a kind of more suitable scheme is proposed in conjunction with the accompanying drawings.Usefulness sheet material such as listed support, support, base, chassis, car body and guide rail and section bar shape the back with welding or connector assembling by design among the figure.Each bearing, joint, rotating disk, wheel etc. are with the assembling of foundry goods processing back.Oil cylinder selects for use the standard type of φ 80,60 to get final product, and all the other are all processed and assembling by the conventional design of machinery and hydraulic technique.Fig. 1 is this pusher side TV structure schematic diagram, and Fig. 2 is an A-A sectional structure schematic diagram, among the figure
