Composition and technical parameters of multi-sliding lifting doors for "large lifting doors"
It is composed of six systems: door body, guide rail, counterweight, seal, transmission and power. According to the size of the opening, it is determined that the lifting door is composed of several door panels, that is, N lifting door.
Usually, the balance is achieved by using the counterweight, which is equipped with the counterweight track. Through the safe and reliable operation of the door opener, it has the characteristics of low failure rate and can realize multi-block linkage, electric, manual and automatic control.
For the super large multi-door, the special hoist for lifting is used as dynamic balance mode, which saves the space of counterweight.
The working principle is that the wire rope is wound in the dynamic and static pulleys, and the action of opening and closing doors is realized by chain drive and pulley drive, so that each door plate runs at different speed of transmission ratio, and finally reaches the position of opening and closing doors at the same time.
When the door body is designed as steel structure, polyurethane board and new heat preservation material can be used in the non-daylighting structure; only when daylighting is required, sunshine board or new material with good heat preservation and light transmittance can be used.
The track is composed of several grooves, and the sealing material is EPDM and industrial brush, which has the characteristics of low temperature resistance, weatherability, smoothness and good elasticity. Drive pulley and sprocket are processed and heat treated with high quality carbon steel.
Specialty ___________ point
1. Start and stop smoothly without load impact.
2. The door body is composed of many blocks, which can effectively utilize the height space of the building structure.
3. Fall-proof gourds can be selected for door blocks.
4. The infrared protection system can be selected in the door area.
5. The power part can flexibly select the upper part or the lower part to facilitate inspection and maintenance.
Techniques, Skills, References and Numbers
1. Opening speed: 0.1-0.3m/s
2. Service temperature: -35 ~45 ~
3. Wind pressure resistance: According to local climate and user requirements, arbitrary wind pressure requirements can be designed;
4. Motor and reducer: Domestic and imported professional industrial door opener and hoist can be selected.
5. Power supply of control system: configure according to local supply voltage range;
Ying, Yong, Fan and Wei
Suitable for super-wide and super-high gate with small stacking space on both sides and limited top height. It needs to be designed according to the actual size and mechanism of the entrance. It can be widely used in large and small hangars, Shangchao entrance, Convention and Exhibition centers, industrial plant.
