Abstract
The utility model discloses a test apparatus used for measuring the consistency of the liquid concrete. The utility model is composed of a bedplate (1) and a bottom frame (2). The utility model is characterized in that the bottom frame (2) is provided with a bent lever (3); when the bent lever (3) is wrenched downwards, a hinged cam (7) on the bent lever drives the bedplate (1) to rise; the bedplate (1) arrives in the specified height, just leaves the cam (7) and falls off; when the bent lever (3) is wrenched upwards, the cam slips the bedplate (1) and returns to the initial position. The test apparatus solves the problem that the foreign congener test device is uneasy to realize the free fall of the test plate and ensures the accuracy of the test result on the basis of the convenient operation.
Description
The utility model belongs to the test unit of measuring the chutable concrete denseness.
Along with the application of super plasticizer and chutable concrete, slump consistancy test no longer can satisfy the requirement of concrete test, and just must measure concrete denseness with slump test this moment.China does not still have the test standard and the equipment of this respect at present, and external slump test equipment also is based on English, two kinds of code test equipment of moral basically.The equipment (see figure 4) of regulation all is to be made of platen and underframe among equipment (see figure 3) of stipulating among the British standard (BS) BS 1881:Part 105:1984 and DIN DIN 1043 Toil 2.Platen is provided with handle.The limit for height parts of control platen hoisting depth are housed on the underframe.During test, on platen, place the chutable concrete of some,, allow it freely fall then to produce vibration by manually platen being mentioned.Concrete flows through several vibration generation on platen of regulation, determines concrete consistometric value according to its liquidity then.When using above-mentioned two kinds of equipment to do experiment, because operating personnel will be with certain power when mentioning platen, therefore be difficult to not allow platen and limit for height parts produce collision, and platen just produces reacting force once collision, be freely to fall no longer just when falling, certainly vibrating effect also will change thereupon, and test findings also will be affected.
The purpose of this utility model provides a kind of improved testing equipment.It also is to be made of platen and underframe, but owing to be provided with the platen take-off and landing device on underframe, does not produce the purpose of any back-lash phenomenon when having realized that because of face platen is mentioned.This device is made of curved bar and hinge joint cam, is characterized in that simple structure is easy to use.
The utility model is realized in the following manner.Underframe front end in testing apparatus is established a bearing, link a curved bar (see figure 1) with bearing pin on the bearing, the curved bar front end is a recess configurations, trough rim is provided with spring leaf, cam with the bearing pin hinge joint is housed in the groove, and the front end of cam is the arc shape (see figure 2).When moving curved bar downwards, cam just drives platen and raises, and platen moves along the camber line position of cam.When reaching the height of regulation, platen breaks away from the arc part of cam just and comes off downwards, produces vibration behind the cushion block of bump underframe.When upwards moving curved bar, cam contact platen also turns round because of being obstructed, then slip over platen and rotate, return to original position, so just can carry out next round-robin operation by the elastic force of spring leaf and the eccentric weight of self.During test, as long as operating personnel grasp the time of rising and falling, just can finish test job at an easy rate.
Below will tie the platform accompanying drawing is described further embodiment of the present utility model.
Fig. 1 is the chutable concrete tester organigram of installing take-off and landing device
Fig. 2 is the take-off and landing device organigram
The proving installation organigram of Fig. 3 for stipulating in the British standard (BS)
The proving installation organigram of Fig. 4 for stipulating in the DIN
Each sequence number is respectively among the figure: 1---platen, 2---underframe, 3---curved bar, 4---, bearing pin, 5---bearing, 6---bearing pin, 7---cam, 8---spring leaf.
Size according to the rules and weight are produced test platen (1), and then weld out a underframe (2) of pad platen (1) with angle steel, and connect together by the end of hinge joint mode with platen (1) and underframe (2).Two short ribs of underframe (2) front end welding are used to install curved bar (3) bearing (5).Bearing (5) is processed by two 30 * 30 * 3 millimeters angle steel, has diameter on it and be 16 millimeters pin shaft hole.The base plate of bearing (5) each with on two short ribs that are bolted to underframe (2).Standoff distance is 26 millimeters.Curved bar (3) is that 24 millimeters, length are that 55 millimeters sleeve pipe is welded with 24 * 24 * 110 millimeters square steel and diameter, and its axis angle is 120 degree.Curved bar (3) is anterior to be 8 millimeters axis hole through being processed to form one 40 * 16 * 20 millimeters groove (see figure 2), producing diameter in the both sides of groove.Its aperture center is apart from 8 millimeters of curved bar (3) front ends, apart from 10 millimeters of bottom lands.In the rear end of square steel be the crooked position of curved bar (3) process diameter be 16 millimeters axis hole in case with bearing hinge joint, 97 millimeters of the centre distance curved bar front ends of this axis hole.In addition, making a thickness with the plain edition steel is that 15 millimeters cam (7), cam (7) is 45 degree angle fan-like patterns, long 84 millimeters of front end camber line, and the shaft hole diameter of rear end is 8 millimeters.25 millimeters of the centre distance front end camber lines of this axis hole, with the distance of rear end camber line then be 9.5 millimeters.With after cam (7) hinge joint is in groove, use another root bearing pin (4) that curved bar (3) is linked on bearing (5) with bearing pin (6) again.Bolt hole below the bearing (5) is made rectangular-shaped along the curved bar axis direction, can adjust the hoisting depth that platen (1) requires by the position that moves forward and backward bearing like this.With two screws a spring leaf (8) is fixed on the recessed trough side part of curved bar (3), and allows an end of spring leaf (8) stretch to groove.When curved bar (3) when upwards moving, cam (7) just touches platen (1) revolution, and rotates then on the base plate that drops on groove slipping over platen (1) under the effect of spring leaf (8), returns to initial original position.
Employing has the testing equipment of platen take-off and landing device to be tested, and has overcome the influence of operation factors to test result effectively.No matter be or at the construction field (site), the utility model all has good usability and playback in the laboratory.
