Description
Technical field
This utility model relates to pavement of road detection apparatus field, particularly to a kind of pendulum friction coefficient determinator base.
Background technology
Portable pendulum tester is one of testing equipment conventional in the on-the-spot test of highway subgrade road surface, and it is for measuring the antiskid value of bituminous paving, graticule or other materials test specimen, to evaluate road surface or ground surface material test specimen anti-slide performance under dampness.Rear fulcrum angle and the base of the base of traditional portable pendulum tester are to be connected together through the hinges, form a T-type structure, thus ensure instrument stablizing in test process, use leveling serew at the fulcrum of chassis three, be finely adjusted when working in coordination for instrument leveling and check its length.But this portable pendulum tester there is the problem that although the T-type structure being hinged rear fulcrum angle and base formation has certain Stabilization, but it is formed without triangle on the whole to fix, this has resulted in process of the test, when accommodating, instrument entirety can shake, thus add the error of test, it is impossible to evaluate the antiskid index on road surface accurately.Meanwhile, the leveling serew length of three fulcrums of base is too short, inconvenient when carrying out leveling and fine setting, it is difficult to meet requirement during pavement detection.Therefore, study a kind of portable pendulum tester base can stablized and conveniently finely tune extremely to be necessary.
At present, Chinese patent market having a Authorization Notice No. be CN203658235U, which disclose and a kind of reinforce adjustable portable pendulum tester base, including main shaft and base, also include the strengthening frame of the equilateral triangle being made up of three connecting rods and three add long screw;Wherein, by a fixing connection between each two connecting rod, the end of connecting rod is fixed on the sidewall of pipe;Strengthening frame is positioned at the lower section of base, and three pipes and three fulcrum one_to_one corresponding of base on strengthening frame, pipe is fixed by adding long screw with corresponding fulcrum;The lower end adding long screw passes downwards from base and pipe successively, its adjustable length passed.
Above-mentioned patent still suffers from being disadvantageous in that: base uses integrally formed structure, rubs in pendulum-type and examines after coefficient measuring instrument tests, and former state can only place storage and compares and take up space, and also can only move by whole instrument when mobile, and portability is poor.

Further, described stabiliser bar is respectively arranged at two ends with fixture block, described front bearing centre position and rear support female thread cylinder b sidewall and is respectively provided with the draw-in groove of clamping stabiliser bar.
By using technique scheme, stabiliser bar cocker ground connection is arranged between front bearing and rear support, improves the portability of base.Front bearing and the draw-in groove on rear support is coordinated, it is possible to be arranged between front bearing and rear support by more stable for stabiliser bar, improve the structural strength of base by being arranged on the fixture block at stabiliser bar two ends.
Further, described stabiliser bar is in the width of front bearing one end more than the width being in rear support one end.
By using technique scheme, grafting column is needed on front bearing, needed firmer structural strength to enable column to be plugged on front bearing by stable on bearing before, the stabiliser bar that front bearing is roomy with front end coordinates, when pendulum friction coefficient determinator is measured, column can be more stable support swing arm swing, reach promote measurement accuracy effect.
Further, described female thread cylinder a two ends are provided with female thread lining.
By using technique scheme, for increasing integraty and the stability of front bearing and rear support so that front bearing and rear support are the most accurate in the data measured by pendulum friction coefficient determinator.
Further, described female thread liner outer wall lower end is provided with the groove for fixing female thread lining.
By using technique scheme, female thread lining is fixed in female thread cylinder a, prevents when adjusting base level, rotate regulation bolt, make female thread lining transfer cannot be adjusted to required level point, and affect the accuracy of pendulum friction coefficient determinator.
In sum, this utility model has the advantages that compared with contrasting patent, this utility model improves the portability of pendulum friction coefficient determinator by utilizing detachable base, and while ensure that pendulum friction coefficient determinator stability by the structure using triangular framing, alleviate the weight of pendulum friction coefficient determinator so that the portability of pendulum friction coefficient determinator promotes further.While setting up the structural strength increase that stabiliser bar can make base between in the base, increase the stability of base.
