Description

A kind of blast furnace open hole machine cart parking buffer unit

Technical field

The utility model is related to blast furnace open hole machine technical field, and more particularly to a kind of blast furnace open hole machine cart parking is slow Flushing device.

Background technology

At this stage in blast furnace production process, blast furnace open hole machine is one of important casthouse equipment, when blast furnace taps a blast furnace every time Tapping hole must be opened with it, its performance and efficiency directly influences the normal production of blast furnace.Wherein large vehicle walking revolution is oily Cylinder is the cushion cylinder of built-in buffer, mainly prevents the inertia when iron notch drill cart return stop excessive, to pivoted arm and Bearing and adjusting screw, the oscillating bearing of angling cylinder produce shock to cause to damage between beam-and-rail；And play buffering well and make With, it is to avoid equipment fault.Found by actually used situation, because the oil cylinder of band buffering is expensive, the life-span is typically on 1 year left side It is right；Once buffer is damaged, integral replacing oil cylinder is needed, maintenance cost is high.Simultaneously online to change oil cylinder, the engineering time is long；To height Stove Influence of production is larger, can only be changed within the turn(a)round of regulation plan.Each position bearing of iron notch drill can bear to touch before changing Power is hit, the abrasion of failure propagation and kit is often resulted in；Above is problem demanding prompt solution, but in addition to cushion cylinder is changed Without other more preferable solutions.

Utility model content

The utility model is in order to solve the above-mentioned technical problem, there is provided a kind of replacement device of cushion cylinder, realizes big garage Walk the steady of slew gear to be operated without impact, operation and maintenance cost can be reduced while transformation simple to existing equipment again.

The utility model is realized by following technical measures：A kind of blast furnace open hole machine cart parking buffer unit, Including A iron notch drills pivoted arm, B vertical shafts, base, E angling cylinders and its two external F hydraulic oil pipes, power source, C grades of iron, D Adjustable throttle valve and G pressure release oil pipes, the C grades of iron are fixed in the outside that A iron notch drill pivoted arms fix one end, and the D is adjustable Formula choke valve is correspondingly arranged at the C grades of outside of iron, and a F hydraulic oil pipe of the D adjustable throttle valves connection E angling cylinders is simultaneously External G pressure releases oil pipe, the F hydraulic oil pipes and G pressure releases oil pipe are connected with power source respectively.

Preferably, the D adjustable throttle valves are fixed in base by mounting bracket and inside is provided with telescoping spool, it is described Valve element outboard end is contacted with C grades of iron lateral surface.

Preferably, the section of the C grades of iron is wedge arcuation.

After using abovementioned technology, the E angling cylinders and its two external F hydraulic oil pipe external connection powers source parts and Hydraulic Station constitutes loop, drives A iron notch drills pivoted arm to complete gyration by E angling cylinders, outside linkage A iron notch drill pivoted arms C grades of iron on wall, the C grades of control of the complete field uninterrupted of telescoping spool of the wedge arcuation end face driving D adjustable throttle valves of iron, Change the retraction speed of E angling cylinders so as to oil circuit control flow rate.After A iron notch drill pivoted arms beat tapping outlet to be finished, return D adjustable throttle valve oil circuit control flows constantly diminish during position, until closing, A iron notch drills pivoted arm is returned in the process Rotary speed is gradually reduced, and improves the shock problem after parking.

Compared with prior art, the utility model beneficial effect can be learnt according to the narration to such scheme：

1st, due to using D adjustable throttle valves, it is possible to achieve regulation of the external choke valve to oil circuit oil return completes oil cylinder Cushioning effect, with maintenance Simple durable, is easy to maintenance.

2nd, the C grades of wedge arcuation design of iron, realizes that A iron notch drills pivoted arm controls E angling cylinders by D adjustable throttle valves Oil circuit flow there are different rotating speeds in diverse location.

3rd, this utility model simple structure, easily operated, is widely portable to the onsite application of various iron notch drills, significantly Reduce regular maintenance cost.
