[0024] Fig. 1 Fig. 1 is a structural schematic view of the safety guard rail device of the utility model;

[0025] Fig. 2This is a schematic diagram of the connection structure between the slider and the safety railing.

[0026] The components include: rodless cylinder 1, safety guardrail 2, slider 3, solenoid valve 4, air pipe 5, speed control valve 6, air source pipe 7, water separator 8, pressure reducing valve 9, oil mist lubricator 10, fixed rod 11, connecting rod 12, connecting block 13, moving block 14, spring 15, first pin 16, and second pin 17. Detailed Implementation

[0027] like Figs. 1-2 As shown, a safety guardrail device in this embodiment includes a rodless cylinder 1 and a safety guardrail 2 distributed vertically. The safety guardrail 2 is connected to the slider 3 of the rodless cylinder 1. The safety guardrail 2 is driven to rise and fall by the rodless cylinder 1. In this way, since the rodless cylinder 1 is smaller in volume than the hydraulic cylinder, the overall volume of the device can be reduced, thereby reducing the space occupied. Moreover, there is no need to install a guide rod, which can avoid jamming during the raising and lowering of the safety guardrail 2 and improve the stability of operation.

[0028] Both the rodless cylinder 1 and the safety guardrail 2 are made of aluminum alloy, thereby reducing the overall weight;

[0029] It also includes a solenoid valve 4, which is a bidirectional electrically controlled, center-sealed solenoid valve. The air inlet and outlet of the rodless cylinder 1 are both connected to air pipes 5, and both air pipes 5 are connected to the solenoid valve 4. Both air pipes 5 are equipped with speed regulating valves 6. The air inlet of the solenoid valve 4 is connected to an air source pipe 7, which is connected to an external air source. Air is delivered from the air source pipe 7 to the solenoid valve 4 through the air source. A water separator 8, a pressure reducing valve 9, and an oil mist lubricator 10 are sequentially arranged on the air source pipe 7 along the air flow direction. The water separator 8 is used to separate moisture from the air, the pressure reducing valve 9 is used to regulate the air pressure, and the oil mist lubricator 10 is used to atomize lubricating oil into tiny oil droplets for subsequent lubrication. The bidirectional electrically controlled, center-sealed solenoid valve is used to control the raising or lowering of the safety railing 2. Even if the air source is cut off or the air source valve is closed, the safety railing 2 will not fall and injure people, thus improving safety.

[0030] Of course, the closing or opening of safety guardrail 2 is interlocked with the operation of chemical short fiber processing equipment. When safety guardrail 2 is closed, the subsequent processing equipment runs at high speed. When safety guardrail 2 is opened, the subsequent processing equipment slows down or stops, which can prevent personal safety accidents caused by high-speed operation.

[0031] The slider 3 of the rodless cylinder 1 is connected to the safety guardrail 2 through two connectors, which are evenly distributed around the vertical center line of the slider 3.

[0033] Two first pin shafts 16 are fixedly arranged on the sliding block 3, the two first pin shafts 16 are coaxially arranged, the two first pin shafts 16 correspond to the two connecting rods 12 respectively, second pin shafts 17 are arranged on the two sliding blocks 3 respectively, both ends of the connecting rod 12 are rotatably sleeved with the first pin shaft 16 and the second pin shaft 17 respectively, the first pin shaft 16 is parallel to the second pin shaft 17;

[0034] During the starting of the rodless cylinder 1, the sliding block 3 is driven to ascend and descend, the ascending and descending of the sliding block 3 drives the safety guard 2 to ascend and descend through the first pin shaft 16, the connecting rod 12, the second pin shaft 17, the moving block 14, the fixed rod 11 and the fixed block in sequence, when the safety guard 2 descends to the ground and the ground is inclined, relative rotation is generated between the connecting rod 12 and the first pin shaft 16, that is, the safety guard 2 is driven to rotate, so that the bottom of the safety guard 2 can be closely attached to the inclined ground, thereby avoiding the existence of the gap between the safety guard 2 and the ground, and improving the safety, and when the sliding block 3 descends after the safety guard 2 contacts the ground, the moving block 14 is driven to relatively move on the fixed rod 11, and the spring 15 is deformed, thereby playing a buffering role, avoiding the rigid impact of the safety guard 2, and playing a protection effect on the safety guard 2;

[0035] In summary, the overall volume and weight are reduced; the ascending and descending of the safety guard 2 is controlled by the bidirectional electric control middle-seal type electromagnetic valve, and even when the gas source is cut off or the gas source valve is closed, the safety guard 2 will not fall down to cause injury, thereby improving the safety; without the need of adding a guide rod, the safety guard 2 can be prevented from being stuck during the ascending and descending, thereby improving the stability of operation; the bottom of the safety guard 2 can be closely attached to the inclined ground, thereby avoiding the existence of the gap between the safety guard 2 and the ground, and further improving the safety; the spring 15 plays a buffering role, thereby avoiding the rigid impact of the safety guard 2, and playing a protection effect on the safety guard 2.
