Description
Technical field
The utility model relates to the drive unit that is mainly used in industrial break, also can be used for various industrial valves, gate, the drive controlling of directional swing device and clamp device, be widely used in industries such as lifting, transportation, metallurgy, mine, harbour, building, particularly a kind of electro hydraulicthruster.
Technical background
The product that existing pusher designed for nineteen seventies, have many problems or deficiency aspect product specification: complete machine is made up of more than 40 component, and some component structural complexity, and manufacturability is poor; Sealing configuration mostly is mechanical sealing, and the seepage phenomenon is often arranged in the working procedure; Piston non-productive work face is big, causes piston area and oil cylinder volume to increase, and work fluid weight increases; Many rotatable parts such as coupling, stuffing box gland, bearing, rotating shaft are arranged between motor and the impeller, cause pusher in the course of the work, energy consumption height, rate of fault height.In a word, existing YT-320 electro hydraulicthruster ubiquity complex structure, material consumption, worker consume greatly, and manufacturability is poor, the cost height, sealing is poor, and in-fighting is big, the rate of fault height, efficient is low, shortcomings such as inconvenient maintenance.
The content of model utility
The technical problems to be solved in the utility model provides simple in structure, low cost of manufacture, and good airproof performance, the efficient height, easy to maintenance, a kind of pair of push rod electro hydraulicthruster that rate of fault is low.
In order to solve above-mentioned technical problem, the two push rod electro hydraulicthrusters of the utility model, its formation is an oil cylinder, fixed motor on the oil cylinder, oil cylinder inner carrier mount push rod, push rod stretches out oil cylinder, it is characterized in that: motor output shaft gos deep into oil cylinder and connects torque transmission device, and torque transmission device connects the piston assembling.
As further improvement of the utility model, oil cylinder is a through hole, oil cylinder upper and lower end sealing and fixing oil cylinder cover.
As further improvement of the utility model, oil cylinder is divided into the thin oil cylinder of thick oil cylinder in top and bottom, and two secondary push rods of thin in-oil cylinder piston mount, two secondary push rods upper end fixed joint crossbeams, secondary crossbeam are fixing push rod upwards.
As further improvement of the utility model, described torque transmission device is the torque drive slideway, for inner chamber is tetragonal sleeve pipe and the square slide bar that is complementary with it that is provided with within it.
As further improvement of the utility model, the piston assembling is made up of piston, impeller, support, rotating shaft, bearing; Piston top is connected with support by bolt, forms an active chamber therebetween, and impeller is connected with rotating shaft by key in cavity, and self-locking nut locking is arranged, and on supporting, rotating shaft square upper end is connected with slideway by bearing fixing in rotating shaft.
The utility model characteristics are: oil cylinder is designed to through hole, is convenient to oil cylinder inner wall processing; By reducing the non-productive work face of piston, and dwindle oil cylinder volume and oil filling amount.Increase by two secondary push rods and guarantee that motor still can be installed between two push rods; Simplify transmission part, piston, impeller, rotating shaft are assembled into one, the torque transmission device (slideway) that installs the band cavity on motor shaft additional is to improve transmission efficiency; All adopt the Sealing sealing, stop oil seepage phenomena.This pusher configuration is simple, reduce by about ten main parts size than existing product, and its every technical performance index does not have any reduction.Because structural simplification, cost of production has reduced by 30%, and ouput force has improved 25%, and oil seepage phenomena is stopped substantially, and rate of fault reduces, and obviously prolong working life, keeps in repair convenient, quick.
Description of drawings
Be described in further detail below in conjunction with accompanying drawing and mode of execution of the present utility model:
Fig. 1 is the sectional arrangement drawing of the two push rod electro hydraulicthrusters of the utility model.
Fig. 2 is the left view of the two push rod electro hydraulicthrusters of the utility model.
Embodiment
As shown in Figure 1, oil cylinder 20 lower ends are connected with base 18 by bolt, and the upper end is connected with cylinder cap 7 by bolt, and piston assembling 19 is contained in the oil cylinder 20, is connected with push rod 10 by secondary crossbeam 21, stop collar 11 are housed to guarantee the rated travel of pusher on the push rod 10.Push rod 10 tops are connected with crossbeam 2, and crossbeam 2 tops are equipped with connecting rod 1 and can be connected with external equipment.Motor 4 is connected with cylinder cap 7 by bolt, and its shaft extension is passed cylinder cap 7 and stretched in the oil cylinder 20, is connected with transmission device (slideway) 9 by key 6.In the slideway 9 is cavity, and when the piston assembling was risen, rotating shaft 12 can enter in slideway 9 cavitys.A certain amount of hydraulic oil is arranged in the oil cylinder 20.The piston assembling mainly supports 14 rotating shafts, 12 bearings 13 to form by piston 19 impellers 15.Piston 19 tops are connected with support 14 by bolt, form an active chamber therebetween, impeller 15 is connected with rotating shaft 12 by key 16 in cavity, and self-locking nut 17 lockings are arranged, and rotating shaft 12 is fixed in the support by bearing 13: its upper end (square) is connected with slideway 9.
Working principle:
When 1, switching on, motor main shaft drive slideway makes the impeller high speed rotating in rotating shaft and the rotating shaft.In-oil cylinder fluid produces pressure difference under centrifugal action, and this pressure official post fluid is drawn to the piston bottom by piston top, forms high pressure in the piston bottom, forces piston and push rod and crossbeam fixed thereon to rise rapidly.When piston rose to apical position, (pusher is finished its working stroke) piston bottom kept constant voltage.
When 2, cutting off the power supply, impeller stops the rotation, and piston descends rapidly under load forces and action of gravity own, gets back to initial position and forces fluid to flow into piston top again.
