Description
Technical field
The utility model relates to the construction project technical field of quality detection, particularly belongs to a kind of the used plastic pipe of construction project is carried out the gauge length device that vertical relaxation shrinkage detects.
Background technology
In engineering construction, the sample of used tubing being got some by the requirement need of relevant regulations carries out vertical relaxation shrinkage mensuration.Before the mensuration, need on sample, to draw two circumference graticules of 100 millimeters apart with scriber.In order to obtain accurate mensuration effect, two above-mentioned graticules should be high-visible, and spacing is accurate, and error must not be greater than 0.25 millimeter.But the line of at present used scriber is thicker, and degree of accuracy is difficult to guarantee, and spacing adjustment inconvenience, and the running time is long, and work efficiency is not high.
The utility model content
The purpose of the utility model is to provide the vertical relaxation shrinkage of a kind of novel plastic pipe to measure the gauge length device, reaches to simplify procedures, and improves the purpose of distance between bench marks degree of accuracy.
The vertical relaxation shrinkage of the plastic pipe that the utility model provided is measured the gauge length device, comprises frame, and positioning and clamping mechanism, rotating mechanism and chalker are set on the frame; It is characterized in that; Described positioning and clamping mechanism is made up of bearing, mandrel and anchor clamps, and bearing is seated on the frame, and mandrel passes in the middle of bearing; Through threaded engagement, anchor clamps are installed on the medial end of mandrel between mandrel and the bearing; Described rotating mechanism comprises motor, rotating shaft and gear train between the two, and on frame, the medial end of rotating shaft is equipped with contact through support and Bearing Installation in rotating shaft; Described chalker is positioned at the side of tubular product sample, is made up of scriber, roll adjustment bar, push rod, installation sleeve; Scriber is installed on the roll adjustment bar, and the roll adjustment bar is fixed on the leading section of push rod, and is relative with tubular product sample; Push rod passes in the middle of installation sleeve, and both are slidingly matched; Installation sleeve is fixed on the frame, establishes spring between installation sleeve and the push rod.
The vertical relaxation shrinkage of the plastic pipe that the utility model provided is measured the gauge length device, before the detection, adjusts two positions of scriber on the roll adjustment bar, makes the requirement of its spacing coincidence detection standard, fixing then getting final product.During detection, the tubular product sample of suitable length and corresponding caliber is placed between contact and the anchor clamps, it is grasped; Starter motor; The rotation of drive tubular product sample, the flicking push rod makes scriber slip over gently from the tubular product sample surface; Can accomplish gauge length work, have time saving and energy saving, reasonable in design, easy and simple to handle, gauge length good effect accurately.
Description of drawings
Accompanying drawing partly discloses the specific embodiment of the utility model, wherein,
Fig. 1, the utility model front elevation;
Fig. 2, the utility model is overlooked part sectioned view.
Embodiment
Like Fig. 1, shown in Figure 2, the vertical relaxation shrinkage of the plastic pipe that the utility model provided is measured the gauge length device, and positioning and clamping mechanism, rotating mechanism and chalker are set on the frame 10.Described positioning and clamping mechanism is made up of bearing 3, mandrel 2 and anchor clamps 4.Bearing is seated on the frame, and mandrel passes in the middle of bearing, passes through threaded engagement between mandrel and the bearing.Anchor clamps are installed on the medial end of mandrel, and rotation mandrel can adjust the position of anchor clamps.For ease of operation, the outboard end of mandrel has handle 1, is convenient to rotation mandrel.For adapting to the tubular product sample of different tube diameters, the internal diameter of anchor clamps is stepped, thereby constitutes some grooves of different-diameter.
Described rotating mechanism comprises motor 9, rotating shaft 7 and gear train 8 between the two, and obviously, rotating shaft should be through support and Bearing Installation on frame.The medial end of rotating shaft is equipped with contact 6.Contact and anchor clamps lay respectively at the two ends of tubular product sample 5, and the external diameter of contact is stepped, thereby constitute some boss of different-diameter, and are corresponding with the groove of anchor clamps.Contact cooperates with anchor clamps tubular product sample is grasped, and makes it to rotate with rotating shaft.Above-mentioned gear train can be the belt gear that belt, belt pulley are formed, and also can be the chain drive that sprocket wheel, chain constitute, or gear drive, and its effect all is the same.
Described chalker is positioned at the side of tubular product sample, is made up of scriber 11, roll adjustment bar 12, push rod 14, installation sleeve 13.Scriber is installed on the roll adjustment bar, through adjusting the requirement that two positions of scriber on the roll adjustment bar can guarantee its spacing coincidence detection standard.The roll adjustment bar is fixed on the leading section of push rod, and is relative with tubular product sample.Push rod passes in the middle of installation sleeve, and both are slidingly matched.Installation sleeve then is fixed on the frame, establishes spring 15 between installation sleeve and the push rod, and after single job was accomplished, as long as unclamp finger, scriber, roll adjustment bar, push rod can rebound automatically, for next operation is got ready.
