Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguisher cylinder testing, in particular to a fire extinguisher cylinder flattening testing machine. Background Art

[0002] Fire extinguishers are devices used to put out fires, usually for initial fire extinguishing or small fires. Fire extinguishers are divided into different types according to the type and purpose of the extinguishing agent. Common types include dry powder fire extinguishers, carbon dioxide fire extinguishers, foam fire extinguishers, water-based fire extinguishers, etc. In the event of a fire, the correct use of a fire extinguisher can effectively control the fire and prevent the fire from expanding. When using a fire extinguisher, you should follow the instructions on the fire extinguisher to ensure your own safety. At the same time, it is also crucial to regularly inspect and maintain the fire extinguisher to ensure that it can be used reliably when needed;

[0003] In some traditional fire extinguisher cylinder flattening tests, the staff generally places the fire extinguisher cylinder directly on the workbench surface for the flattening test or uses tools to fix the fire extinguisher cylinder directly on the workbench surface. After the fire extinguisher cylinder flattening test is completed, the clamping tool is removed and the fire extinguisher cylinder is taken out;

[0004] There are some problems. Placing the fire extinguisher cylinder directly on the surface of the workbench greatly affects the stability of the fire extinguisher cylinder during the flattening test. Fixing the fire extinguisher cylinder on the surface of the workbench with tools and removing the fire extinguisher cylinder after the fire extinguisher cylinder flattening test are rather cumbersome, which greatly increases the manpower. For this reason, we propose a fire extinguisher cylinder flattening test machine. Utility Model Content

The clamping mechanism is respectively located on the left and right sides of the workbench, which is convenient for clamping the fire extinguisher cylinder to be flattened, providing stability for the subsequent flattening test. At the same time, the clamping mechanism is reset after the fire extinguisher cylinder flattening test is completed, which is convenient for taking away the fire extinguisher cylinder after the flattening test. The operation is simple and labor-saving.

[0009] Furthermore, it also includes a control switch group, which is arranged on the front side of the pressure frame, and the input end of the control switch group is electrically connected to an external power supply for stable control.

[0011] Furthermore, the clamping mechanism includes a slide rail, a mounting frame, a pin shaft, a lifting inclined slider and a side clamping rod. The slide rail is arranged on the left and right sides of the bottom wall of the base, and the inside of the slide rail is slidably connected with the lifting inclined slider. The left and right sides of the front and rear inner walls of the base are provided with mounting frames, and the inner ends of the mounting frames are rotatably connected with the side clamping rods through pin shafts. The lower ends of the side clamping rods are rotatably connected with small pin shafts, and the outer arc surfaces of the small pin shafts are provided with rollers, which are in contact with the inclined surfaces of the longitudinally adjacent lifting inclined sliders, so as to facilitate the clamping of the fire extinguisher cylinder that needs to be flattened for testing.

[0012] Furthermore, the clamping mechanism also includes a lifting inclined groove, a lifting block and a slide groove. The left and right sides of the bottom wall of the base are provided with slide grooves, and the inside of the slide grooves are slidably connected with lifting blocks. The outer side surfaces of the lifting inclined sliding blocks are provided with lifting inclined grooves, and the front ends of the lifting blocks are in contact with adjacent lifting inclined grooves to facilitate lifting and clamping.

[0013] Furthermore, mounting plates are provided at both left and right ends of the rear side surface of the base, and electric telescopic rods are installed on the rear side surfaces of the mounting plates by bolts. The telescopic ends of the electric telescopic rods pass through the mounting plates and the rear side walls of the base in sequence and are fixedly connected to the rear sides of the longitudinally adjacent jacking blocks, and the input ends of the electric telescopic rods are electrically connected to the output ends of the control switch group for stable driving.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] 1. The staff will place the fire extinguisher cylinder that needs to be flattened on the surface of the workbench. At this time, in order to ensure the stability of the fire extinguisher cylinder during the subsequent flattening experiment, the staff will operate the control switch group. After the control switch group is adjusted, the electric telescopic rod starts to drive, and the telescopic ends of the two electric telescopic rods push the adjacent jacking blocks forward. At this time, the jacking block moves forward inside the slide slot, and the front end of the jacking block slides along the inclined surface of the jacking inclined slot and gradually lifts the adjacent jacking inclined slider upward. The jacking inclined slider moves upward along the track of the slide rail. At this time, the rollers at the lower ends of the two side clamping rods on the same side are affected by the changes in the inclined surface of the jacking inclined slider during the upward movement. At this time, the rollers rotate with the adjacent pin shaft as the center, and the side clamping rod rotates. At this time, the spring is subjected to tension, and the side clamping rod and the jacking inclined slider cooperate to clamp the fire extinguisher cylinder that needs to be flattened to stabilize it, which is convenient for clamping the fire extinguisher cylinder to be flattened, and provides stability for the subsequent flattening experiment.

[0017] 2. When the fire extinguisher cylinder flattening test is over, the staff controls the switch group. After the control switch group is adjusted, the electric telescopic rod starts to drive, and the telescopic ends of the two electric telescopic rods pull the adjacent jacking blocks backward. At this time, the jacking block moves backward inside the slide groove, and the jacking inclined slider gradually loses the jacking force of the jacking block. At this time, under the action of gravity, the jacking block moves downward inside the slide rail. At this time, the side clamping rod loses the inclined extrusion of the jacking inclined slider. At this time, the spring loses tension, so that the side clamping rod and the jacking inclined slider stop clamping the flattened fire extinguisher cylinder. After the fire extinguisher cylinder flattening test is over, the clamping mechanism is reset to facilitate the removal of the fire extinguisher cylinder after the flattening test.

After the control switch group 13 is regulated, the motor 12 starts to drive, and then the output shaft of the motor 12 drives the screw rod 7 to rotate, and then drives the slider 10 to move downward under the cooperation of the thread, and then drives the guide rods 9 on both sides to slide inside the adjacent guide slide grooves 8, and then drives the pressure plate 6 to move downward, and then starts to squeeze the fire extinguisher cylinder downward. When the fire extinguisher cylinder flattening experiment is over, the staff controls the switch group 13, and after the control switch group 13 is regulated , the electric telescopic rod 4 starts to drive, and the telescopic ends of the two electric telescopic rods 4 pull the adjacent jacking blocks 27 backward.
