Abstract
The invention discloses an electric cylinder for a road intercepting system. The electric cylinder for the road intercepting system comprises a screw rod (1), a nut (2), a push rod (3), a guide key (4), a cylinder barrel (5), a three-phase asynchronous motor (6), a coupler (7), a connecting seat (8) and an arriving proximity switch (9). The screw rod (1), nut (2), guide key (4) and cylinder barrel (5) form spiral transmission, and the nut (2) drives the push rod (3) to move to play a role of pushing. The electric cylinder uses the three-phase asynchronous motor (6), the travel is controlled through the arriving proximity switch (9), the control is easy to perform, and the cost is low; a speed reducer and a transmission mechanism are omitted, so that the structure is simple, the size is small, and the cost is lowered; the push rod (3) action speed is improved by means of the large starting torque of the three-phase asynchronous motor (6). The electric cylinder completely meets requirements of easiness in control, quick action, compact structure, small size and low cost and is especially suitable for the road intercepting system.
Description
Technical field
The present invention relates to a kind of electric cylinder, particularly a kind of electric cylinder for road intercepting system.
Background technology
Electric cylinder is a kind of by motor-driven straight line acting device.General electric cylinder is mainly made up of servomotor, planetary reducer, transmission mechanism, transmission case, screw rod, nut, push rod, feather key and cylinder barrel.In road intercepting system, need to utilize electric cylinder will block bucket and eject fast, require electric cylinder control simple, be swift in motion, compact conformation, size are little, and cost is low.Its positioning precision, thrust are not had to too high request.Conventional electric cylinder control complexity, huge structure, cost is high, and is not suitable for road intercepting system.
Summary of the invention
The object of the invention is to provide a kind of electric cylinder for road intercepting system, solves conventional electric cylinder control complexity, huge structure, the problem that cost is high.
For an electric cylinder for road intercepting system, comprising: screw rod, nut, push rod, feather key and cylinder barrel, also comprise: threephase asynchronous, shaft coupling, Connection Block and the approach switch that puts in place.Screw rod axle journal is connected by bearing with Connection Block, nut and screw rod are threaded connection, push rod is placed on nut external cylindrical surface, the end face flange of the end face of push rod and nut is connected by screw, feather key is connected by screw on the external cylindrical surface of push rod, cylinder barrel is placed on the external cylindrical surface of push rod, the flange of the end face of cylinder barrel and Connection Block one end is connected by screw, feather key is placed in the gathering sill of cylinder barrel inner cylinder face and forms linear slide with cylinder barrel and is connected, the flange of threephase asynchronous and the Connection Block other end is connected by screw, the output shaft of threephase asynchronous is connected by shaft coupling with the input of screw rod, the screwed hole putting in place on approach switch and cylinder barrel wall is spirally connected.
Threephase asynchronous drives screw rod rotation, between screw rod and nut, forms worm drive, thereby drives nut along screw axial translation, and nut drives push rod along the axial translation of cylinder barrel, and feather key stops nut and push rod circumferentially to rotate, and play the guiding role.Push rod is by stretching out in cylinder barrel, and performance promotes function.The approach switch that puts in place detects the position of nut, once nut moves to the approach switch place that puts in place, the approach switch that puts in place sends the signal that puts in place, makes threephase asynchronous stall, thereby controls the movement travel of push rod.
This electric cylinder adopts threephase asynchronous, without driver, by the approach switch control stroke that puts in place, controls simple, with low cost; Adopt threephase asynchronous and screw rod associated mode, save decelerator, transmission mechanism, structure is simplified, size is little, further reduces costs simultaneously; Utilize the feature that threephase asynchronous machine staring torque is large, can improve the rapidity of push rod action.This electric cylinder meets completely to be controlled simply, is swift in motion, and compact conformation, size are little, and the requirement that cost is low is applicable to being applied in road intercepting system very much.
