Description

Technical Field

[0002] With the rapid development of urban rail transit, subway screen doors, as a safe, energy-saving and environmentally friendly equipment, have been widely used in the field of rail transit.

[0003] Due to the operation principle of the subway, in order to ensure the personal safety of passengers, it is required that the shield door should be insulated from the subway platform after installation, and at the same time be at the same potential as the train, return rail, etc. However, the insulation between the shield door and the platform has become a problem that troubles engineering and technical personnel in the industry, and has not been well solved. Even if it can meet the insulation value requirements stipulated by the state when it is just installed, the insulation effect will decline or even fail in the future operation due to the influence of factors such as the environment and the aging of the insulation parts, which will bring hidden dangers to the personal safety of passengers and affect the normal operation of the subway. The fundamental reason for this phenomenon is that the dust and water vapor on the track side have damaged the insulation parts during long-term operation, and the dust and other particles are easy to accumulate on the insulation parts to form a conductive area with poor reliability.

It serves as an isolation and insulation between the platform 1 and the shielding door chassis 4 through the insulating pad 3 to avoid electric shock. However, when the outside of the insulating pad 3 is contaminated with dust and impurities and there is a hidden danger of forming a conductive area, the air pump 10 is operated and exhausts air through the exhaust pipe 11, and air can be sucked by the dust head 6 to form a negative pressure outside the insulating pad 3. Impurities and dust can be introduced into the dust collection tube 8 through the transmission pipe 7 and filtered by the inner filter cartridge 9. When the screw-mounted loading and unloading mechanism is opened, the inner filter cartridge 9 can be taken out and the internal cleaning can be carried out.

[0024] The screw-mounting loading and unloading mechanism includes an internal threaded cover 13 and an external threaded ring 14. The external ring side of the top end of the dust collection tube 8 is connected to the bottom end of the external threaded ring 14. The internal threaded cover 13 is detachably screwed on the outside of the external threaded ring 14, and the output end of the transmission tube 7 is connected to the inner side of the internal threaded cover 13; when the external threaded ring 14 is closed on the outside of the internal threaded cover 13, the upper part of the dust collection tube 8 is sealed to prevent gas leakage and maintain stable air pressure. After the external threaded ring 14 is screwed and removed from the outside of the internal threaded cover 13, the upper mouth of the dust collection tube 8 can be opened to facilitate the removal and cleaning of the inner filter cartridge 9.

[0025] The handle 15 is also included, and one side of the outer end of the internal thread cover 13 is connected to the inner side of the handle 15; by pinching the handle 15, the internal thread cover 13 can be screwed, which facilitates the screwing and unscrewing of the internal thread cover 13 on the outer side of the external thread ring 14, thereby improving convenience.

[0026] The fixing bolt 12 also includes an anti-loosening washer 16 , which is arranged on the outer side of the lower part of the fixing bolt 12 ; the anti-loosening washer 16 can be used to support the fixing bolt 12 upward when it is tightened, so as to prevent the fixing bolt 12 from being loosened and improve stability.

[0027] It also includes a support frame 17, which is connected between the lower side of the front end of the shielding door base frame 4 and the bottom end of the dust collection tube 8; the dust collection tube 8 can be supported by the support frame 17 to prevent the dust collection tube 8 from loosening and falling off from the shielding door base frame 4, thereby improving stability.

[0029] In summary, when a shielding door base insulation structure is used, the shielding door base frame 4 is isolated and arranged on the upper side of the platform 1 through the insulating pad 3, and the fixing bolts 12 pass through the ring 5 and the insulating pad 3, and are screwed and fixed on the inner side of the screw groove ring 2. When the fixing bolts 12 are tightened, they can be supported upward through the anti-loosening pad 16 to prevent the fixing bolts 12 from being screwed loose. The insulating pad 3 serves as an isolation and insulation between the platform 1 and the shielding door base frame 4 to avoid electric shock. However, when the outside of the insulating pad 3 is contaminated with dust and impurities, there is a hidden danger of forming a conductive area. The vacuum pump 10 is running, The exhaust is discharged through the exhaust pipe 11 and can be sucked by the dust collector head 6. When the external threaded ring 14 is closed on the outside of the internal threaded cover 13, the upper part of the dust collector 8 is sealed, and a negative pressure is formed outside the insulating pad 3. Impurities and dust can be introduced into the dust collector 8 through the transmission pipe 7 and filtered by the inner filter cartridge 9. When the handle 15 is twisted to remove the external threaded ring 14 from the outer side of the internal threaded cover 13, the upper mouth of the dust collector 8 can be opened to facilitate the removal and cleaning of the inner filter cartridge 9. In addition, a series of information can be displayed through the information board 18, which is convenient for reading, use and operation, thereby improving convenience.
