Abstract
The invention discloses a general corrugated pipe stretching test clamp. The general corrugated pipe stretching test clamp comprises a pull rod, a shaft, a supporting seat, a supporting arm and a fixed clamp, wherein a pull ring is arranged on the top end of the pull rod, the pull rod is connected with the shaft, the shaft is connected with the supporting seat, the supporting arm is hinged to the supporting seat by virtue of a bolt, the fixed clamp is hinged with the supporting arm, the bottom end of the fixed clamp is provided with a movable plate and a fixed plate, and the movable plate is connected to the fixed plate in a sliding manner and fixed by virtue of a bolt. The general corrugated pipe stretching test clamp is simple in structure, convenient to disassemble and install, capable of firmly and reliably clamping a corrugated pipe to be tested and applicable to the corrugated pipe model numbers in a given range. The general corrugated pipe stretching test clamp is connected with a corrugated pipe by virtue of the fixed clamp, and is applicable to different convex surface widths of the corrugated pipe by changing the position of the movable plate, capable of guaranteeing the firmness in connection, convenient to install, capable of being folded when in storage so as to save the storage space, and convenient for fixing and performing the stretching test on the corrugated pipe.
Description
Technical field
The present invention relates to a kind of field that firmly effectively can clamp corrugated tube, the particularly general corrugated pipe stretching test clamp of one.
Background technology
At present, corrugated tube is mainly used in the plumbing facility in municipal administration, building and farmland, and corrugated tube needs to possess certain intensity, to have enough serviceable life under comparatively rugged environment.According to the requirement of standard GB/T/T19647-2005, the ring stiffness of corrugated tube must be greater than 2.0kN/m2, this just needs the tension test of being correlated with to corrugated tube, but it is of the prior art specially for the fixture of corrugated tube tension test, be specific customization, can not be fixed the corrugated tube of different radii, and the land width difference of corrugated tube also needs to change fixture, uses very inconvenient.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of general corrugated pipe stretching test clamp, to solve the defect that the above-mentioned corrugated pipe stretching test clamp caused in prior art does not have versatility.
For achieving the above object, the invention provides following technical scheme: a kind of general corrugated pipe stretching test clamp, comprise pull bar, axle, supporting seat, sway brace and geometrical clamp, the top of described pull bar is provided with draw ring, and pull bar is connected with described axle, axle is connected with described supporting seat, described sway brace by bolted splice in supporting seat, described geometrical clamp and sway brace hinged, the bottom of geometrical clamp is provided with portable plate and fixed head, portable plate is slidably connected to fixed head, and is bolted.
Preferably, described supporting seat and described axle are by casting integrated shaping.
Preferably, described sway brace has 4, and is articulated with the four direction of described supporting seat respectively.
Preferably, the bottom of described pull bar is provided with hole, and the size in hole matches with described axle, and is fixed by set bolt.
Preferably, described general corrugated pipe stretching test clamp be two with the use of.
The beneficial effect of above technical scheme is adopted to be: structure of the present invention is simple, easy accessibility, reliable to the firm grip of corrugated tube to be measured, go for the corrugated tube model in certain limit, be connected by geometrical clamp with corrugated tube, and the land width of different corrugated tubes can be suitable for by the position changing portable plate, ensure that the fastness of connection, easy for installation, can accept during storage to save memory space, thus can be fixed and tension test corrugated tube easily.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is that the present invention coordinates schematic diagram with corrugated tube.
Wherein, 1-draw ring, 2-pull bar, 3-set bolt, 4-axle, 5-supporting seat, 6-bolt, 7-sway brace, 8-geometrical clamp, 9-corrugated tube, the general corrugated pipe stretching test clamp of 10-first, the general corrugated pipe stretching test clamp of 11-second, 81-fixed head, 82-portable plate.
Embodiment
The preferred embodiment of the present invention is described in detail below in conjunction with accompanying drawing.
Fig. 1 and Fig. 2 shows the specific embodiment of the present invention: a kind of general corrugated pipe stretching test clamp, comprise pull bar 2, axle 4, supporting seat 5, sway brace 7 and geometrical clamp 8, the top of described pull bar 2 is provided with draw ring 1, draw ring 1 is for being connected with stretching machine during tension test, pull bar 2 is connected with axle 4, the bottom of pull bar 2 is provided with hole, the size in hole matches with axle 4, axle 4 is installed in inlet hole, then fixed by set bolt 3, such structure can be convenient to carry out tension test and be convenient to maintenance and dismounting.
Axle 4 is connected with supporting seat 5, and described supporting seat 5 and axle 4, by casting integrated shaping, can ensure the intensity between supporting seat 5 and axle 4, avoid being damaged when carrying out tension test, adding the life-span of use.Sway brace 7 is articulated with supporting seat 5 by bolt 6, geometrical clamp 8 is hinged with sway brace 7, the bottom of geometrical clamp 8 is provided with portable plate 82 and fixed head 81, portable plate 82 is slidably connected to fixed head 81, and fixed by bolt 6, and sway brace has 4, and be articulated with the four direction of supporting seat 5 respectively, general corrugated pipe stretching test clamp be two with the use of.
Corrugated tube 9 is fixed between two general corrugated pipe stretching test clamps, geometrical clamp 8 can be realized freely movable in certain angle by supporting seat 5 and sway brace 7, hinged between sway brace 7 and geometrical clamp 8, portable plate 82 can slip on fixed head 81, the groove distance between portable plate 82 and fixed head 81 is enable to adapt to the land width of corrugated tube 9, and fixing by the groove distance between portable plate 82 and fixed head 81, realize fixing corrugated tube 9, when the corrugated tube 9 that diameter is larger is installed on geometrical clamp 8, the angle between sway brace 7 is larger; When the corrugated tube 9 that diameter is less is installed on geometrical clamp 8, the angle between sway brace 7 is less.
Two general corrugated pipe stretching test clamps and corrugated tube 8 are matched after regulating, pull bar 2 is tightened with the set bolt 3 of the junction of axle 4 and is fixed, bolt 6 between sway brace 7 and supporting seat 5 is tightened fixing, tighten fixing between geometrical clamp 8 and sway brace 7, bolt 6 between portable plate 82 and fixed head 81 is tightened fixing, ensures that the result of the tension test that can not cause because of the fixing instability of fixture in the process of carrying out tension test is inaccurate.
Structure of the present invention is simple, easy accessibility, reliable to the firm grip of corrugated tube 9 to be measured, go for corrugated tube 9 model within the scope of certain size, be connected by geometrical clamp 8 with corrugated tube 9, and the land width of different corrugated tubes 9 can be suitable for by the position changing portable plate 82, ensure that the fastness of connection, easy for installation, can accept during storage to save memory space, thus can be fixed and tension test corrugated tube 9 easily.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, and without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
