Abstract
The invention discloses a kind of pump line plugging mechanism of automotive pump, comprise steel pipe, the tube wall of described steel pipe is provided with radial slot and closure plate matches, described closure plate is provided with inner end plate and outer end plate, described inner end plate is the arc matched with steel pipe hole wall, described outer end plate is stretch in the plate outside steel pipe notch, the radial depth of the radial slot on described tube wall is not less than the pore radius of steel pipe, the outer peripheral face of steel pipe is provided with two bearings vertically, in the sliding hole fitted on described two bearings of guide rod, the outer end plate of described closure plate is provided with the hole relative with the hole on described bearing, and it is slippery with described guide rod.The present invention has the remarkable advantage not having material flow when pump line moves and go out.
Description
Technical field
The present invention relates to a kind of blocking technology, particularly a kind of pump line plugging mechanism of automotive pump.
Background technology
Automotive pump needs frequent mobile pump line to carry out concrete casting to the cylinder of diverse location, beam in building construction process, time mobile, automotive pump quits work, normal condition concrete can not flow out from pump line, but because the change of pump line height and angle all can make the material in pump line flow out in moving process, cause concrete waste, pollute job site, even cause potential safety hazard.
Summary of the invention
The object of the invention is to provide the pump line plugging mechanism of a kind of automotive pump that material can not flow out from pump line when a kind of pump line moves.
Technical scheme of the present invention is, a kind of pump line plugging mechanism of automotive pump, comprise steel pipe, it is characterized in that: the tube wall of described steel pipe is provided with radial slot and closure plate matches, the inner of described closure plate is arc, the outer end of described closure plate is square plate or arc, when closure plate injects in radial slot, and the arc of the inner is when contacting with steel tube inner hole diapire, the arc side face of the arc of this inner and a part of arc endoporus wall of steel pipe fit, and the square plate of closure plate outer end or the outside of arc expose to the outside of steel pipe, the radial depth of the radial slot on described tube wall is not less than the radius of steel pipe, the outer peripheral face of steel pipe is provided with two bearings vertically, described two bearings are respectively equipped with a hole, the square plate or arc of the outer end of described closure plate are provided with the hole relative with the hole on described bearing, in described hole on the hole that guide rod is sliding to be fitted on described two bearings and the square plate of closure plate outer end or arc.
The present invention has the remarkable advantage not having material flow when pump line moves and go out compared with the prior art.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention; Fig. 2 is the left view of Fig. 1; Fig. 3 is the structural representation of closure plate.
Detailed description of the invention:
There is one section of flexible flexible pipe 1 upper end of automobile pump line and goes out concrete steel pipe 3, and be tube connector 2 between this steel pipe and flexible pipe, the effect of flexible pipe is convenient to bend and is sent material downwards.The steel tube body of the present invention outside flexible pipe establishes plugging mechanism, closure plate 4 inserts in the radial slot in steel pipe walls, the inner of described closure plate is arc 9, its outer end is square plate or arc, the radius of wherein inner arc is identical with the radius of steel tube inner hole, when closure plate injects in the radial slot of steel pipe, and the arc of the inner is when contacting with steel pipe hole diapire, the arc side face of the arc of this inner and a part of arcuate socket face of steel pipe fit, and the square plate of closure plate outer end or the outside of arc expose to the outside of steel pipe, the degree of depth of the radial slot in described steel pipe walls is more than or equal to the radius of steel pipe.For the ease of insertion and the extraction of closure plate, the square plate 11 of the outer end of closure plate or the outer face of arc establish handle 5; In order to fix when closure plate inserts steel pipe, prevent it from skidding off from tube seat, the side face of steel pipe arranges two bearings 6 vertically, in the sliding hole fitted on described bearing of guide rod 7, it is relative with the hole on described bearing that the square plate of the outer end of closure plate or the outside of arc are provided with hole 10, and join with described guide rod is sliding, the middle part of described guide rod is provided with handle 8.
Method of operating of the present invention and operating principle: when pump line needs to move to another casting station, under automotive pump quits work, manually closure plate is inserted in chamfer putting steel tube, again the guide rod on steel pipe bearing is injected in the guide rod hole on closure plate, can be shifted, when arriving appointment station, pull out guide rod and extract closure plate out, automotive pump can be started and carry out having cast.
