Abstract
A drop test machine for a fire extinguisher is characterized by comprising a mould base fixed on a base, wherein, a test piece is arranged in the mould base; a cam mechanism is installed below the base and connected with a motor and a speed reducer; a through hole is formed at the center of the base; a jacking device is arranged in the through hole; the upper end of the jacking device is in contact with the test piece positioned on the mould base, and the lower end of the jacking device is in contact with the cam mechanism; and a control box is connected with the motor and the speed reducer for controlling the cam mechanism. The drop test machine has a simple structure, is convenient to operate, can effectively detect the fire extinguisher, and guarantees the quality of the fire extinguisher.
Description
Technical field
The utility model relates to a kind of device that is used for fall-down test, specifically refers to a kind of flame snuffer drop machine.
Background technology
Regulation according to 7.1.4.2 in the 7.1.4 money among the standard GB 4351.4-2005 " hand fire extinguisher " " the jet performance experiment after the dry-chemical extinguisher shake is hit ": with the erectility of flame snuffer; From 15mm height with 1 hertz frequency thickness 60mm ± 1mm to horizontal positioned; Long 300mm ± 5mm freely falls on the steel plate of wide 300mm ± 5mm 500 times.Therefore need research and develop a kind of device that can carry out fall-down test in practice to flame snuffer.
Summary of the invention
The purpose of the utility model is to design a kind of device that can carry out fall-down test to flame snuffer, to detect whether National standard of flame snuffer.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The flame snuffer drop machine is characterized in that: said testing machine comprises the mould bases that is fixed on above the base, and test specimen is placed in the mould bases the inside; Cam mechanism is installed below base, and cam mechanism connects motor and speed reduction unit; The center place has through hole, is placed with jacking system in the through hole, and end in contact is arranged in the test specimen of mould bases on the jacking system, following end in contact cam structure; Control box is controlled cam mechanism through being connected with speed reduction unit with motor.
Control box adopts robot scaler.
The device that can send sound and light signal is installed in the control box.
The utility model is simple in structure, easy to operate, can effectively test to flame snuffer, guarantees the flame snuffer quality.
Description of drawings:
Fig. 1 is the utility model structural representation;
Description of reference numerals:
1. test specimen, 2. mould bases, 3. cam mechanism, 4. control box, 5. base, 6. jacking system.
Embodiment:
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the utility model structural representation, and is as shown in the figure, and the flame snuffer drop machine comprises the mould bases 2 that is fixed on above the base 5, and mould bases 2 the insides are placed test specimen 1 and are used to guarantee that test specimen 1 remains erectility.Cam mechanism 3 is installed below base 5, and cam mechanism 3 connects motor and speed reduction unit; Base 5 centers have through hole, are placed with jacking system 6 in the through hole, and end in contact is arranged in the test specimen 1 of mould bases 2 on the jacking system 6, following end in contact cam structure 3.The speed vibration drop that this equipment adopts motor after the reductor speed governing, to export 1 revolutions per second is 15mm; Cam mechanism 3 is through jacking system 6; With discharging suddenly behind the test specimen 1 jack-up 15mm, test specimen 1 presents erectility, can run-off the straight under the shielding and sustain of mould bases 2; Thereby freely falling of the state of being kept upright clashed into the base 5 of thick 60mm.
