Abstract
The utility model discloses a dual-purpose Marshall stability tester clamp, which relates to the technical field of Marshall stability testers. The dual-purpose Marshall stability tester clamp is characterized in that an upper inner clamp and a lower inner clamp are produced in the clamping grooves of an upper clamp and a lower clamp of a Marshall stability tester respectively, a fixing groove is formed in the lower interior of the clamping groove of the upper clamp, and a fixing pin matched with the fixing groove is arranged at the outer side of the upper inner clamp. When a pressure test is performed on pellets with different diameters, the pressure bearing values of the tested pellets can be measured only by increasing and reducing the inner clamps in the case with no replacement of the clamp and no increase for equipment; and moreover, the dual-purpose Marshall stability tester clamp is simple and convenient to operate, labour-saving and time-saving, as well as efficient and stable.
Description
Technical field
The utility model relates to road test instrument technical field, particularly relates to Marshall stability analyzer, specifically dual-purpose Marshall stability analyzer fixture.
Background technology
Along with the fast development of social communication, High Grade Bitumen Pavement is able to widespread use, and the bituminous pavement of take is expanded as main transportation network is forming with continuous.In the process of construction of bituminous road, in order to guarantee pavement quality, just must sample and loading pressure testing the asphalt of road surface pavement, for measuring stability and the anti-deformability of moulding of asphalt.And method for measuring and conventional means are exactly by Marshall stability apparatus, the stability of the asphalt of different proportionings and flow valuve to be measured.And even this guarantees that to improving the quality of asphalt pavement quality is significant.But, in the work of practical measurement, generally the sampling pellet of asphalt is had to two kinds, a Φ 152mm, a kind of Φ 101.6mm, if measure these two kinds of pellets, just need to be with two Marshall stability analyzers, or change the fixture of degree of stability analyzer, if adopt the former ，Ze enterprise to step up its investment, if adopt the latter, reduced efficiency, therefore, must take measures to above existence problem solved.
Summary of the invention
The technical problems to be solved in the utility model is: make a kind of Marshall stability analyzer fixture that can be dual-purpose, this fixture is divided into inside and outside two-layer, can be in the situation that not changing fixture or increasing equipment, only in increase and decrease, fixture just can be measured Φ 152mm and two kinds of pressure bearing values of testing pellets of Φ 101.6mm, and easy and simple to handle, time saving and energy saving, efficient stable.
Technical solution adopted in the utility model is: fixture and lower interior fixture in making respectively in the upper fixture of Marshall stability analyzer and the clip slot of lower clamp, below upper fixture clip slot interior, have pickup groove, in the outside of upper interior fixture, be provided with the fixed pin matching with pickup groove.
Described upper fixture and the clip slot internal diameter of lower clamp are 152mm, consistent with the external diameter of upper interior fixture and lower interior fixture; In upper, the clip slot internal diameter of fixture and lower interior fixture is 101.6mm.
The utlity model has following beneficial effect:
1, easy and simple to handle, saving of work and time.When pressure testing different-diameter pellet, do not need to take apart degree of stability analyzer or change fixture, as long as the force value that just can accurately measure different-diameter pellet is laid out or taken off to upper and lower interior fixture.
2, efficient rapidly, accurate quick.In changing during upper fixture if fixed pin is extracted from pickup groove or is injected can, being used in conjunction with of fixed pin and pickup groove, can make to measure different-diameter pellet rapider, pressure measurement all will be adjusted interior fixture at every turn, thereby makes measurement more quick.
3, reduce cost, increase benefit.Had dual-purpose Marshall stability analyzer fixture just can avoid using the situation of two degree of stability analyzers or two sleeve clamps, not only manufacturer's cost, also makes applying unit reduce investment, thereby has realized doulbe-sides' victory.
Accompanying drawing explanation
Fig. 1 is the utility model diagrammatic cross-section.
In figure: 1. fixture 6. fixed pins in fixture 3. pickup groove 4. lower clamp 5. times in going up on fixture 2..
Embodiment
As shown in Figure 1, in the upper fixture 1 of Marshall stability analyzer and the clip slot of lower clamp 4, make respectively in fixture 2 and lower interior fixture 5; In upper, the external diameter of fixture 2 and lower interior fixture 5 is 152mm, and identical with the internal diameter of upper fixture 1 and lower clamp 4, upper interior fixture 2 can be contained in the clip slot of fixture 1, and lower interior fixture 5 can be contained in the clip slot of lower clamp 4.
Still as shown in Figure 1, below upper fixture 1 clip slot interior, have pickup groove 3, in the outside of upper interior fixture 2, be provided with the fixed pin 6 matching with pickup groove 3.When installing interior fixture 2,3 li of the pickup grooves that the fixed pin on upper interior fixture 26 is injected to upper fixture 1 can, in taking-ups during interior fixture 2, on the contrary.
Also as shown in Figure 1, the clip slot internal diameter of upper interior fixture 2 and lower interior fixture 5 is 101.6mm.
Claims (2)
1. dual-purpose Marshall stability analyzer fixture, it is characterized in that: fixture (2) and lower interior fixture (5) in making respectively above in the upper fixture (1) of Marshall stability analyzer and the clip slot of lower clamp (4), interior below at upper fixture (1) clip slot has pickup groove (3), is provided with the fixed pin (6) matching with pickup groove (3) in the outside of upper interior fixture (2).
2. dual-purpose Marshall stability analyzer fixture as claimed in claim 1, is characterized in that: described upper fixture (1) and the clip slot internal diameter of lower clamp (4) are 152mm, consistent with the external diameter of upper interior fixture (2) and lower interior fixture (5); In upper, the clip slot internal diameter of fixture (2) and lower interior fixture (5) is 101.6mm.
