Abstract
The utility model relates to a pull rod device for a headstock gear. Hoops are arranged on a plurality of buttresses of the device. A plurality of pull rods penetrate through the hoops, and are connected through a plurality of flanges. An axis connecting line of the buttresses is slightly arc-shaped, and the slightly bent ends of the pull rods are connected through the flanges after being slightly bent downwards. According to the pull rod device, the slightly bent ends of the pull rods are slightly bent downwards, and are matched with the slightly arc-shaped axis connecting line of the buttresses naturally for pulling, so that the phenomenon of locking in the hoops is avoided.
Description
Technical field
The utility model relates to a kind of headstock gear draw rod device.
Background technology
At present, in many hydraulic engineerings, conventionally need to open by headstock gear, headstock gear pull bar wherein connects rear-inclined by flange and is arranged on several buttresses and by anchor ear and fixes, and the axle center of several buttresses is on same straight line.Because pull bar is longer, it there will be slight curving in transportation, and therefore, the pull bar axle center after installation very likely, not on same straight line, therefore, in drawing process, there will be pull bar stuck in anchor ear, causes headstock gear not open or to close.
Summary of the invention
The purpose of this utility model is to provide can not there is the stuck a kind of headstock gear draw rod device in anchor ear of pull bar.
The technical scheme that the utility model is taked is: a kind of headstock gear draw rod device, on several buttresses, be equipped with anchor ear, some pull bars pass anchor ear and link together by some flanges, it is characterized in that buttress axle center connecting line is camber line slightly, and the slight curving end of pull bar connects by flange downwards again.
Adopt the utility model, because the slight curving end of pull bar is downward, be slightly camber line with buttress axle center connecting line and match, when pulling, do things by following nature, just can not produce stuck phenomenon in anchor ear.
accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Sequence number in figure represents: pull bar 1, buttress 2, anchor ear 3, buttress axle center connecting line 4 and flange 5.
the specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
With reference to Fig. 1, on several buttresses 2 of this headstock gear draw rod device, be equipped with anchor ear 3, some pull bars 1 pass anchor ear 3 and link together by some flanges 5, wherein the buttress axle center connecting line 4 of several buttresses 2 is camber line slightly, and the slight curving end of pull bar 1 connects by flange 5 downwards again.Because the slight curving end of pull bar 1 is downward, be slightly camber line with buttress axle center connecting line 4 and match, when pulling, do things by following nature, just can not produce the stuck phenomenon in anchor ear 3 of pull bar 1.
Claims (1)
1. a headstock gear draw rod device is equipped with anchor ear on several buttresses, and some pull bars pass anchor ear and link together by some flanges, it is characterized in that buttress axle center connecting line is camber line, and the curved end of pull bar connects by flange downwards again.
