Abstract
The utility model relates to an impact tester which is characterized by comprising a base, a support, a conduit and an impact hammer, wherein the support is fixedly arranged on the base by a compacting piece and a fastening piece, the support is parallelly connected with the conduit which is provided with a through hole by the fastening piece, the impact hammer is suspended in the conduit by the through hole and a pin, and the top of the impact hammer is connected with a tube for resetting the impact hammer. The impact tester has the advantages that the distance and the height of the impact hammer and a transparent piece to be tested can be exactly guaranteed, the impact hammer can be exactly smashed at the right middle of the transparent piece to be tested, and the pin can be conveniently and quickly plugged and unplugged, therefore, the impact hammer can perform the freefall motion quickly and stably. Furthermore, the impact tester is simple in structure, convenient to install and use, and higher in test reliability.
Description
Technical field
The utility model belongs to the electric device for valve technical field, particularly relates to a kind of impact test apparatus that is used for the destructive test of flame-proof valve valve electric device view window.
Background technology
Usually, the explosion-proof type electric device for valve that is used for explosive gas atmosphere is provided with view window.The transparent material that is used to make view window should be according to the regulation of standard GB 3836.1-2000 " explosive gas atmosphere electrical installation part 1: " general requirement " ", and the view window transparent member of flame-proof valve valve electric device must be carried out impulse test.Its requirement is: the impact energy that the transparent material of making view window produces in the time of should be able to bearing the satisfactory steel ram hammer of quality by the specified altitude freely falling body, do not break for qualified to test back transparent member to be tested.In known technology, generally adopt following test method: the ram hammer that the hand-held conformance with standard of test operation personnel requires, and make the tested transparent member of its distance from bottom reach the height of standard-required, transparent member is placed on the steel platform; Unclamp hand then, make the ram hammer freely falling body pound position, center, promptly accomplish impulse test in transparent member.Though this test method is simple, the height of ram hammer can not accurately be located, and rocking of staff be prone to impact the accurately center position of hit transparent member to be tested of hammer, so just possibly cause test findings inaccurate, untrue.
Summary of the invention
The utility model provides a kind of simple in structure for solving the technical matters that exists in the known technology, and is easy to install and can improve the impact test apparatus of test reliability.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: impact test apparatus; It is characterized in that: comprise pedestal, support, conduit and ram hammer; Be fixed with support through compressing member and securing member on the said pedestal; Said support mounts ram hammer through perforation and pin through the parallel conduit that is shaped on perforation on it that is connected with of securing member in the said conduit, is connected with at the ram hammer top to be used for the flexible cord that it resets.
The utility model can also adopt following technical scheme:
Said pedestal is the steel pedestal.
Said compressing member adopts the platen structure.
Said ram hammer upper end is shaped on the perforation that is used to mount.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; Being about to conduit and support is installed in parallel on the steel pedestal; Ram hammer is worn through pin and is hung in the conduit, can accurately guarantee like this: 1, the distance height of ram hammer and tested transparent member; 2, ram hammer can accurately be pounded the position, center that drops down onto tested transparent member; 3, pin can make things convenient for fast insert-pull, makes the movement of falling object of carrying out of ram hammer quick and stable.In addition, this apparatus structure is simple, and is easy to install and can improve the reliability of test.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, pedestal; 2, conduit; 3, support; 4, pin; 5, ram hammer; 6, platen; 7, flexible cord; 8, tested transparent member.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, impact test apparatus comprises steel pedestal 1, support 3, conduit 2 and ram hammer 5, is fixed with support 3 through compressing member and securing member on the said pedestal, and in the present embodiment, said compressing member is preferably platen 6.Said support mounts ram hammer 5 through perforation and pin 4 through the parallel conduit 2 that is shaped on perforation on it that is connected with of securing member in the said conduit, is shaped on the perforation that is used to mount in the ram hammer upper end, and the ram hammer top is connected with and is used for the flexible cord that it resets.In the present embodiment, said pin adopts the structure of pulling pin that at one end is shaped on ear handle, and the perforation of passing on the ram hammer 5 of pulling pin is inserted in the perforation of conduit 2, and ram hammer 5 is hung in the conduit 2.Be connected with flexible cord 7 on the ram hammer 5, be mainly used in test and finish and conveniently mention ram hammer and be placed in initial position.
During test, tested transparent member 8 is positioned on the steel pedestal 1 of conduit 2 belows, makes position, tested transparent member center align the center of conduit 2; To pull pin then and 4 extract fast; Ram hammer 5 loses 4 the supporting of pulling pin, and vertical drop is pounded on transparent member, accomplishes impulse test.Through flexible cord 7 ram hammer 5 is mentioned subsequently, and, recover the original state of this impact test apparatus with 4 slotting the hanging in the conduit 2 of pulling pin.At this moment, can tested transparent member be taken off observation, pass judgment on test result.
Claims (4)
1. impact test apparatus; It is characterized in that: comprise pedestal, support, conduit and ram hammer; Be fixed with support through compressing member and securing member on the said pedestal; Said support mounts ram hammer through perforation and pin through the parallel conduit that is shaped on perforation on it that is connected with of securing member in the said conduit, is connected with at the ram hammer top to be used for the flexible cord that it resets.
2. impact test apparatus according to claim 1 is characterized in that: said pedestal is the steel pedestal.
