Abstract
The invention discloses an asphalt stability testing tool which comprises a working table. The working table is provided with a bracket; the top of the bracket is provided with a cross rod; a pressure ball head is fixedly arranged at the bottom side of the cross rod by a pressure sensor; the working table is also provided with a test piece fixture under the cross rod; the test piece fixture comprises a lower pressure head arranged on an ejector rod controlled to move up and down, and an upper pressure head which is matched with the lower pressure head to clamp a test piece and is provided with a press seat matched with the pressure ball head; a displacement sensor is arranged between the upper pressure head and the lower pressure head; the working table is also provided with the bracket, the cross rod and a seal cover for wrapping the test piece fixture in a sealing way. According to the asphalt stability testing tool, a closed test space is formed by the seal cover, and the test space is basically isolated from the external environment, so that the test process is not influenced by the outside, and the test result is accurate; fragments of the test piece produced by the test are blocked in the seal cover, so that the test process is safe, the fragments are easy to clean and collect, and the test result is convenient to analyze.
Description
Technical field
The present invention relates to a kind of pitch testing tool, be specially a kind of Bituminous stabilized degree testing tool.
Background technology
Asphalt degree of stability is a main Detection of content of pitch composite material quality testing, and it can measure asphalt failing load and non-deformability.
The special tester of current general carries out Stabilily parameter to compound.These testers can be measured the related data of sample and show.Need in test process to carry out the actions such as impact punching press to bitumen mixture specimen, once test specimen occurs broken, fragment easily outwards splashes, and except the problem that existence is difficult to cleaning, also can cause security incident, test specimen fragment is difficult to carry out collection analysis in addition.
Summary of the invention
In order to solve above technical matters, the invention provides a kind of Bituminous stabilized degree testing tool, it can easily form airtight test space, test process safety, and test result can carry out analyzing and processing easily.
The technical scheme that the present invention adopts for technical solution problem is:
A kind of Bituminous stabilized degree testing tool, comprise worktable, described worktable is provided with support, the top of support is provided with cross bar, the bottom side of cross bar is fixed with pressure bulb by pressure transducer, worktable is also provided with the piece fixture be positioned at below cross bar, piece fixture comprises the push-down head on the push rod being arranged on a lifting controllable and coordinates with this push-down head the seaming chuck clamped by test specimen, seaming chuck is provided with the wedge mated with pressure bulb, displacement transducer is provided with between seaming chuck and push-down head, described worktable is also provided with by described support, cross bar, the seal closure of piece fixture Mi Bao, the bottom of described seal closure is fixed on worktable, the position of the corresponding piece fixture of seal closure is provided with dodge gate.
As preferred embodiment, described seal closure is transparent configuration.
The invention has the beneficial effects as follows: the present invention utilizes seal closure to form an airtight test space, and test space and external environment condition are substantially isolated, and process of the test can not be subject to external action, and test findings is accurate; Testing the test specimen fragment produced is blocked in seal closure, process of the test safety, and fragment is easy to cleaning and collects, thus conveniently carries out test result analysis.
Accompanying drawing explanation
Be further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of an embodiment of the present invention.
Symbol description: 1-worktable, 2-support, 3-cross bar, 4-push-down head, 5-seaming chuck, 6-seal closure, 7-pressure transducer, 8-pressure bulb, 9-push rod, 10-wedge, 11-displacement transducer, 12-dodge gate.
Embodiment
With reference to Fig. 1, Stabilily parameter instrument of the present invention forms primarily of worktable 1, support 2, cross bar 3, the piece fixture be made up of push-down head 4 and seaming chuck 5, seal closure 6 etc.Controller is provided with in worktable 1.
Support 2 is fixedly installed in worktable 1, and cross bar 3 is positioned at the top of support 2, and the bottom side of cross bar 3 is fixed with pressure bulb 8 by a pressure transducer 7.Piece fixture is installed on worktable 1, is positioned at below cross bar 3.Particularly, push-down head 4 is on the push rod 9 of installation one lifting controllable, and seaming chuck 5 is positioned on push-down head 4, and test specimen can clamp by both cooperations.Corresponding with pressure bulb 8, seaming chuck 5 is provided with the wedge 10 mated with pressure bulb 8.Displacement transducer 11 is provided with between push-down head 4 and seaming chuck 5.The detection data of pressure transducer 7 and displacement transducer 11 are transferred in controller.
When test is carried out, be placed in piece fixture by test specimen to be tested, control push rod action and push-down head 4 is moved up, namely controller can obtain the degree of stability related data of asphalt by the data recording pressure transducer 7 and displacement transducer 11.
Seal closure 6, by support 2, cross bar 3, piece fixture Mi Bao, makes each several part all focus in cover body.Seal closure 6 forms an airtight test space, and test space and external environment condition are substantially isolated, and process of the test can not be subject to external action, and test findings is accurate; Testing the test specimen fragment produced is blocked in seal closure, process of the test safety, and fragment is easy to cleaning and collects, thus conveniently carries out test result analysis.
In a particular embodiment, the mode that this seal closure 6 can adopt bottom to be fixed to worktable 1 is arranged, and now seal closure 6 can not overall take off, and it can arrange dodge gate 12 on the position of corresponding piece fixture.In addition, in order to observation experiment process easily, this seal closure 6 generally adopts transparent configuration to realize.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
