Abstract
The utility model relates to an actuator, in particular to a pneumatic actuator adopting the top-mounted bevel gear transmission. Thepneumatic actuator adopting the top-mounted bevel gear transmission comprises an air cylinder, a traction screw rod, a switching body, a side wheel, a split nut and a switching mechanism controlling the split nut, wherein the traction screw rod is arranged in the air cylinder; the switching body and the split nut are arranged on the traction screw rod in a sleeving manner; the switching body is connected with the side wheel in a linkage manner; and the switching mechanism is arranged on the switching body. With the adoption of an integrated pneumatic and manual driving mechanism, the start and stop of a valve are convenient; the remote automatic control of the valve can be achieved by a remote-control pneumatic driving mechanism; the manual operation can also be conducted under a condition of air exhaustion and power interruption of a system; mounting and maintenance of the valve are facilitated; in addition, the labor intensity and safety risks of operators can be reduced; and the pneumatic actuator is simple in structure and convenient to operate.
Description
Technical field
The utility model relates to a kind of actuator, especially a kind of top dress bevel gear drive pneumatic actuator.
Background technique
The valves such as existing gate plate type gate valve are generally by manual, electronic, pneumatic control.Development along with the modern industry automation, in a lot of applications, require the automatic unlatching of pipeline automatic controlling system valve or close, the pneumatic actuators that adopt are controlled more, and pneumatic valve is in test and the inspection of valve, use in on-the-spot installation, debugging and the maintenance and maintenance process, lose the situation of gas, dead electricity more.In this case, the manual operating device of valve is just very important.Traditional manual-operating mechanism inconvenient operation, and control when transforming structure too complicated.
Summary of the invention
The purpose of this utility model is, a kind of simple in structure, easy to operate top dress bevel gear drive pneumatic actuator is provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of top dress bevel gear drive pneumatic actuator, comprise cylinder, traction screw, traction screw is arranged in the cylinder, also comprise the switching mechanism of conversion body, side wheel, half nuts, control half nuts, conversion body is set on the traction screw, half nuts is set on the traction screw, and conversion body and side wheel are connected, and switching mechanism is arranged on the conversion body.
Of the present utility modelly further be set to: also comprise cone tooth drive wheel, cone tooth driving wheel, cone tooth driving wheel is fixedly connected with side wheel, cone tooth drive wheel is fixedly connected with conversion body, and cone tooth driving wheel and the engagement of cone tooth drive wheel consist of being connected of conversion body and side wheel.
Of the present utility modelly further be set to: comprise that also pinion stand, pinion stand are fixed on the cylinder, at pinion stand an axis hole is arranged, side wheel is fixedly connected with by gear pole with cone tooth driving wheel, and shaft hole sleeve is located on the gear pole.
Of the present utility modelly further be set to: switching mechanism comprises handle and conversion block, and handle is fixedly connected with conversion block.
Of the present utility modelly further be set to: conversion block is rotating to be arranged on the conversion body and to be set on the traction screw, and in the conversion body that half nuts arranges, conversion block and half nuts are connected.
Said structure adopts the driving mechanism of gas, manual one, make the keying convenient operation of valve, can realize by the remote control pneumatic driving mechanism remote auto control of valve, and lose when system in the situation of gas, outage, also can manually-operable, be convenient to installation and the maintenance of valve, also can reduce labor intensity of operating staff and security risk in addition, simple in structure, easy to operate.
Description of drawings
Fig. 1 is the structural representation of present embodiment;
Embodiment
With reference to figure 1 as can be known, a kind of top of the utility model dress bevel gear drive pneumatic actuator, comprise cylinder 1, traction screw 2, traction screw 2 is arranged in the cylinder 1, conversion body 3 is set on the traction screw 2, half nuts 4 is set on the traction screw 2, cone tooth driving wheel 51 is fixedly connected with side wheel 5, cone tooth drive wheel 6 is fixedly connected with conversion body 3, cone tooth driving wheel 51 and 6 engagements of cone tooth drive wheel, consist of being connected of conversion body 3 and side wheel 5, pinion stand 7 is fixed on the cylinder upper cover 11, at pinion stand 7 axis hole 71 is arranged, and side wheel 5 is fixedly connected with by gear pole 52 with cone tooth driving wheel 51, axis hole 71 is set on the gear pole 52, switching mechanism comprises handle 8 and conversion block 9, and handle 8 is fixedly connected with conversion block 9, and conversion block 9 is rotating to be arranged on the conversion body 3 and to be set on the traction screw 2, in the conversion body 3 that half nuts 4 arranges, conversion block 9 is connected with half nuts 4.
The control gear that the pneumatic band of the utility model is manual, by side-mounted or flush mounting type handwheel rotation, the bevel gear and the half nuts that drive pair of meshing rotate; And make cylinder piston and valve rod, the upper and lower motion of flashboard by the traction screw transmission, realize the open and close of valve.When system is in mistake gas, dead electricity, transfer to manually by the switching mechanism COMM communication, can realize the manually-operable of valve, be convenient to using and keeping in repair of valve; When there not being source of the gas, when losing aerodynamic force, operate switching mechanism, half nuts is meshed under the effect of conversion block, finish manual switchover, drive again rotation hand wheel this moment, cooperate by two bevel gears, make the valve rod lifting and drive seal disc and move up and down, finish the unlatching of valve and close, when needs are pneumatic, be transformed into pneumatic mode by switching mechanism, can make half nuts break away from valve rod, finish pneumatic conversion.
