Background technology:
Hydrostatic testing machine is called for short water pressure engine, and water pressure engine is an ingredient important in the welded tube unit, is mainly used in to steel duct water-filling to be measured supercharging, is used to detect the intensity and the compactness of steel pipe.Withstand voltage for detecting steel pipe, water pressure engine needs the process of pressurize in the supercharging operation, requires water pressure engine to stop and can not be subjected to displacement during pressurize, so just need be applied to the insert-pull pin device, and the insert-pull pin device is used for fixing water pressure engine.Water pressure engine is in operational process, and the frame both sides of water pressure engine are provided with beam, and beam is provided with some holes, and the insert-pull pin device is fixed on frame top, and lock is laterally worn in the hole on insert-pull pin device and two beams, promptly plays the fixedly effect of water pressure engine after in the insert-pull pin patchhole.As depicted in figs. 1 and 2, Fig. 1 is the side view of insert-pull pin device in the prior art, and Fig. 2 is the vertical view of insert-pull pin device in the prior art.The insert-pull pin device comprises oscillating oil cylinder 5, gear 1 and insert-pull pin 3, and gear 1 is positioned at the below of oscillating oil cylinder 5, and the both sides of gear are provided with the tooth bar 2 of " L " shape, are provided with bearing pin 4 between tooth bar 2 and the insert-pull pin 3, and gear 1 is connected with a joggle with tooth bar 2.Insert-pull pin is right cylinder, linearly shape.Insert-pull pin is through the position between PLC controller location insert-pull pin and the hole, plug automatically.Insert-pull pin is when plugging operation, and oscillating oil cylinder is swung, the oscillating oil cylinder driven gear, and the gear driven tooth bar, tooth bar pulling insert-pull pin bounces back simultaneously or stretches out.This structure, the rack and pinion serious wear, long more gear changing and the tooth bar of just needing of application time changed frequent and expended cost.In view of this technical matters, press for occur a kind of simple in structure, easy to use, but insert-pull pin can monolateral plug also both sides plug synchronously, the automatic insert-pull pin device of long-lived a kind of water pressure engine.
Summary of the invention:
The purpose of the utility model is to overcome the shortcoming that exists in the prior art, provides a kind of simple in structure, easy to use, but insert-pull pin can monolateral plug also both sides plug synchronously, the automatic insert-pull pin device of long-lived a kind of water pressure engine.
To achieve these goals, the utility model provides a kind of water pressure engine automatic insert-pull pin device, comprises two groups of insert-pull pins and oil cylinder; Wherein, The bottom of said insert-pull pin is provided with holder, and said holder is provided with chute, and the end of said insert-pull pin is provided with the handle of " L " shape; Be provided with bearing pin on the both sides of said holder and the handle of said insert-pull pin, be slidingly connected between said insert-pull pin and the said chute.
One end of one of them said oil cylinder is fixedly connected with bearing pin on said holder one side, and the other end of said oil cylinder is fixedly connected with bearing pin on the handle of insert-pull pin, and said two groups of insert-pull pins are the center symmetry each other.
One of them insert-pull pin can overlap with another insert-pull pin behind central point Rotate 180 degree, and one of them oil cylinder can overlap with another oil cylinder behind central point Rotate 180 degree, and one of them holder can overlap with another holder behind central point Rotate 180 degree.Said two groups of insert-pull pin centers symmetry, two group oil cylinder centers symmetry, two holder center symmetries.
The outstanding advantage of the utility model is: simple in structure, easy to use, but insert-pull pin can monolateral plug also both sides plug synchronously, durable in use.Specific as follows:
Two oil cylinders of the utility model are separately fixed on the bearing pin of two holders, and the other end of oil cylinder is fixedly connected with bearing pin on the handle of insert-pull pin.Two group oil cylinders can work independently, also can synchronous workings, and the corresponding insert-pull pin of each oil cylinder, this structure has been save rack and pinion, has avoided the trouble of the annex of frequent change wearing and tearing, and is durable in use.

Embodiment:
Below in conjunction with accompanying drawing, the utility model is described.
Like Fig. 1-shown in Figure 2, Fig. 1 is the side view of insert-pull pin device in the prior art, and Fig. 2 is the vertical view of insert-pull pin device in the prior art.The insert-pull pin device comprises oscillating oil cylinder 5, gear 1 and insert-pull pin 3, and gear 1 is positioned at the below of oscillating oil cylinder 5, and the both sides of gear are provided with the tooth bar 2 of " L " shape, are provided with bearing pin 4 between tooth bar 2 and the insert-pull pin 3, and gear 1 is connected with a joggle with tooth bar 2.Insert-pull pin is right cylinder, linearly shape.Insert-pull pin is through the position between PLC controller location insert-pull pin and the hole, plug automatically.Insert-pull pin is when plugging operation, and oscillating oil cylinder is swung, the oscillating oil cylinder driven gear, and the gear driven tooth bar, tooth bar pulling insert-pull pin bounces back simultaneously or stretches out.This structure, the rack and pinion serious wear, long more gear changing and the tooth bar of just needing of application time changed frequent and expended cost.
