Abstract
The utility model provides a pull rod travel control device for a tamping coke oven interchanger, which includes a pull rod connected with a power cylinder, a forward direction contact block arranged at one end of the pull rod, as well as a coal gas cock and an air cock connected with the other end of the pull rod and placed in a coal gas pipe and an air pipe respectively; a forward direction travel switch is arranged above the forward direction contact block, and is electrically connected with a controller; the controller is electrically connected with the power cylinder. The pull rod travel control device is characterized in that a reverse direction contact block positioned on one side of the forward direction contact block is arranged on the pull rod, and a reverse direction travel switch electrically connected with the controller is correspondingly arranged above the reverse direction contact block. According to the utility model, the running distances in the forward direction and the reverse direction of the pull rod are accurate, the coal gas cock and the air cock driven by the pull rod can be opened or closed in place, the accuracy of in-place running of the control device is improved, and the problems that the coal gas cock and the air cock cannot be opened and closed in place caused by the facts that the pull rod is longer and physical deformation is easily caused, and further coal gas leakage is generated caused by untight seal are effectively solved.
Description
Technical field
The utility model relates to a kind of travel control device, and particularly a kind of tamping coke furnace exchange board rod stroke control device, belong to Servomechanism manufacturing technology field.
Background technology
The tamping coke furnace exchange board control coal gas and air alternately enter coke oven heating system in the time, to move back and forth by the pull bar that is driven by power cylinder, and make the collision block on pull bar touch travel switch, and after sending controller to process the initiating signal forward or backwards of travel switch, control power cylinder drive pull bar by controller more intermittent mobile, move and open or close gas flue thereby by pull bar, drive cock, finally controlling coal gas, air alternately enters in coke oven heating system.In actual production, deviation appears in the stroke distances while there will be pull bar forward and inverted running, i.e. when stroke switch forward operation put in place, inverted running can't accurately put in place; Otherwise after the travel switch inverted running put in place, the forward operation can not put in place.Will make thus the cock that is connected with pull bar be difficult to accurately put in place, thereby cause gas leak, and cause therefrom potential safety hazard and gas loss, also pollute the environment.Therefore be necessary prior art is improved.
Summary of the invention
For solving in prior art, because the forward and reverse stroke of travel switch is difficult to accurately put in place, and affect accurately open and close of pull bar and cock, and then cause the problems such as gas leak, the utility model provides a kind of travel control device,, to control the shift motion of tamping coke furnace exchange board pull bar, accurately open or close gas cock.
the utility model is completed by following technical proposal: a kind of tamping coke furnace exchange board rod stroke control device, comprise the pull bar that is connected with power cylinder, be located at the forward contact block of pull bar one end, be connected with the pull bar the other end and be placed in respectively gas cock and the air tap of gas pipe and blast main, forward contact block top is the forward stroke switch, the forward stroke switch is electrically connected to controller, controller is electrically connected to power cylinder, it is characterized in that being positioned at forward collision block one side and be provided with reverse contact block on pull bar, oppositely contact block top correspondence is provided with the reverse stroke switch that is electrically connected to controller, so that when forward operation or inverted running, all can just pass through, oppositely contact block with just, the touching of reverse stroke switch, and control exactly rod stroke, thereby coal gas is opened or closed to control cock, air.
The utlity model has following advantages and effect: adopt such scheme, can guarantee that the forward and reverse range ability of pull bar is all very accurate, coal gas, air tap that pull bar is driven can be opened or close and put in place, have improved the accuracy that the control device operation puts in place.Efficiently solve because of pull bar longer, easily produce physical deformation under external force and affect coal gas, the air tap open and close is not in place, thereby cause poorly sealed and produce the problem of gas leak, eliminate safe hidden trouble, improve coke oven production operation environment.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is another status architecture schematic diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
the tamping coke furnace exchange board rod stroke control device that the utility model provides, comprise the pull bar 9 that is connected with power cylinder 7, be located at the forward contact block 8 of pull bar 9 right-hand members, be connected with pull bar 9 left ends and be placed in respectively gas cock 12 and the air tap 13 of gas pipe 3 and blast main 1, the two ends of gas pipe 3 are connected with coke oven heating unit 2 and gas main 11 respectively, blast main 1 is connected with coke oven heating unit 2, forward contact block 8 tops are forward stroke switch 6, forward stroke switch 6 is electrically connected to controller 5, controller 5 is electrically connected to power cylinder 7, the left side that is positioned at forward collision block 8 on pull bar 9 is provided with reverse contact block 10, oppositely contact block 10 top correspondences are provided with the reverse stroke switch 4 that is electrically connected to controller 5, driving gas cock 12 so that pull bar 9 forwards move opens, air tap 13 is closed, thereby while to coke oven heating unit 2, providing coal gas, by the touching of forward contact block 8 with forward stroke switch 6, stop and making controller 5 control power cylinder 7, control exactly the forward stroke of pull bar 9, as Fig. 1, drive when pull bar 9 inverted runnings that gas cock 12 is closed, air tap 13 opens, thereby while to coke oven heating unit 2, providing air,, by the touching of reverse contact block 10 with reverse stroke switch 4, and make controller 5 control power cylinder 7, stop, control exactly the reverse stroke of pull bar 9, as Fig. 2.
