Description
Technical field
The utility model is related to a kind of engineering construction material impact resistant rigid performance test equipment of testing different size.
Background technology
Current, people generally are to adopt different energy to carry out impulse test for the impact resistant rigid of all kinds of different construction materials of test.For example, the pendulum of the different quality by changing Charpy impact machine tester, changing the impact kinetic energy of pendulum, thereby so that existing Charpy impact machine tester can carry out to sample the impulse test of variable energy.Adopt prior art to carry out the impulse test of variable energy, need manpower often to change the pendulum of different size, labour intensity is large, work efficiency is low, particularly when changing the pendulum of larger quality, just seems very inconvenient.
Summary of the invention
The utility model is in order to solve above-mentioned technical matters, the construction material rigid shock that a kind of labour intensity is low, work efficiency is high test machine to be provided.
A kind of construction material rigidity test machine that the utility model proposes, it comprises base, one balance staff case and balance staff are located at base top, one pendulum is hung on the balance staff by fork, drive in addition the drive unit that balance staff rotates, be located at the extension pendulum device on base top, this extension pendulum device comprises: the support plate that is connected with the balance staff case, on support plate, hang many covers hanging and swinging mechanism of the track spacing setting of balance staff swing along described fork, and hanging and swinging mechanism comprises: an end is articulated in the hook on the described support plate, one cylinder, piston rod one end and the Hook of this cylinder are hinged, the other end is articulated on the described support plate, and described hook is hung pendulum or taken off pendulum with the extension balance staff formation on the described fork and cooperates.
Preferably, a side of described balance staff case is provided with and can controls the brake gear that described balance staff turns, stops.
Preferably, described base outer surface of upper is provided with the display device that is connected with described balance staff, and the lower outside of described base also is provided with the computer controller of sample conveying device and accessory drive motion.
The utility model is by arranging many cover hanging and swinging mechanisms, can be so that after being in the pendulum of differing heights position and taking off pendulum, produce different movement velocitys, thereby produce different impact kinetic energies.The utility model has overcome existing defective of carrying out the pendulum impact test of variable energy effectively, can carry out easily and efficiently the impulse test of variable energy.

Embodiment
As depicted in figs. 1 and 2, described construction material rigidity test machine, comprise base, this base is located at the balance staff case 2 on a pair of base top that chevron shaped column 8 consists of, is located at that is made by I-shaped steel section on the base plate and balance staff 60, is hung on pendulum 6 (seeing also Fig. 3) on the balance staff, drives drive unit 7 that balance staff rotates, is located at anvil device (not shown) between two columns 8 of base bottom, is located at the extension pendulum device 5 on base top by fork 24 by base plate 40 and front and back.This extension pendulum device comprises: many covers hanging and swinging mechanism that the support plate 13 that is connected with the balance staff case, the track spacing that swings along fork extension balance staff 25 on support plate arrange, this hanging and swinging mechanism are hung to put or take off pendulum with the extension balance staff formation on the described fork and are cooperated.Laterally be provided with the retracting device 11 of collecting the sample after testing on the base plate 40 between described two columns 8, in the present embodiment, retracting device is tape handler.The front side of described balance staff case 2 is provided with can control the described balance staff 20 moving brake gears 4 that stop, in order to improve the security performance when hanging pendulum.Be provided with protective cover 1 between described two columns 8, sample in order to avoid during impulse test, occurs and jumps out and cause damage in the space hood guard that this protective cover moves pendulum 6.Usually will with the front of described drive unit 7 relative heel posts 8 as operating surface, the outer surface of upper of this column 11 is provided with the display device 3 that is connected with described balance staff 60, in order to show the impact energy of pendulum.Be provided with the sample conveying device 12 corresponding to described anvil device before this heel post, this side also is provided with the computer controller (switch board 10, computer 9) of accessory drive 7 motions.This computer controller can automatically be controlled the extension pendulum of pendulum 6 and take off that pendulum, sample conveying device 12 are delivered to sample on the anvil device automatically, automatically records every data during test.When extension is shown existing accident, can also control brake gear 4 emergency brakes.In the present embodiment, shown in Fig. 3,4, described support plate 13 is two, and symmetry is installed on described base top, and every support plate inside surface is provided with three cover hanging and swinging mechanisms.Fork 24 can swing between these two support plates, and the two ends that hang balance staff 25 on the fork can form to hang pendulum or take off pendulum with a certain hanging and swinging mechanism and cooperate.In conjunction with shown in Figure 5, hanging and swinging mechanism comprises: an end is articulated in hook 15, a cylinder 16 on the described support plate 13 by hook axle 14, piston rod one end of this cylinder and Hook is hinged, the other end is articulated on the described support plate, described hook 15 form to hang pendulum or take off pendulum with extension balance staff 25 on the fork and cooperate.Namely rotate by drive unit 7 driving forks 24 as required, pendulum 6 is lifted certain altitude, make it hang balance staff and cooperate the extension pendulum with a certain hook; When needing test, link up with around its jointed shaft rotation by the piston rod promotion of cylinder, thereby take off pendulum, pendulum moves downward work.
As required as long as rotational swing rod makes it be in different angles and form and hang pendulum with a certain hanging and swinging mechanism on the support plate; After fork takes off pendulum, be in the pendulum of differing heights, the movement velocity that drops to minimum point is not identical, thereby the different impact kinetic energy that produces.The utility model has overcome existing defective of carrying out the Charpy impact test of variable energy effectively, can carry out easily and efficiently the impulse test of variable energy.
