DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to reduce the wear and tear caused by the movement of the lifting rolling shutter door in the prior art, there is a gap between the surface and the slide rail after the door body is closed, which makes the sealing effect of the device poor and the acid mist is easy to leak. If absorbed by the human body, it will endanger life safety. The following describes a fast lifting door for hot-dip galvanizing provided by some embodiments of the utility model in conjunction with the accompanying drawings.

[0023] Embodiment 1:

[0024] In order to avoid leakage of acid mist generated during hot-dip galvanizing, Figure 1 , Figure 2 and Figure 3 As shown, a fast lifting door for hot-dip galvanizing is proposed. An external mechanism 1 is set as the main body of the device. A connecting mechanism 2 is set in each of the two pillars 103. The connecting mechanism 2 forms a closed environment indoors, so that the acid mist is closed and collected to prevent leakage. A driving mechanism 3 is set at the bottom of the two pillars 103. The driving mechanism 3 is used to increase the closing speed of the door body 104.

[0025] In order to improve the sealing effect of the device during the hot-dip galvanizing process, a connecting mechanism 2 is proposed. By installing a fixing plate 208, a through groove 201 is opened on the two pillars 103, and two square grooves 202 are opened in the two pillars 103 located in the through groove 201. Multiple pulleys 203 are rotatably connected in the multiple square grooves 202. A sealing strip a204 is installed on one side of the two pillars 103 located in the through groove 201, and sealing strips b205 are installed on both sides of the two pillars 103 located in the through groove 201. A card block 207 is installed at the bottom of the door body 104, and a card slot 209 is opened on the top of the fixing plate 208. The card block 207 and the card slot 209 can be They are mutually engaged, and the moving path of the door body 104 is limited by the through groove 201. The multiple pulleys 203 are installed and fixed by multiple square grooves 202, so as to reduce the friction between the door body 104 and the inner wall of the pillar 103. The gap between the door body 104 and the inner wall of the pillar 103 is filled by the sealing strip a204 and the sealing strip b205. The block 207 and the slot 209 on the fixing plate 208 are engaged after the door body 104 is closed, so that the bottom of the door body 104 is also closed, so that the sealing effect of the door body 104 after closing is better, and the acid mist in the hot-dip galvanizing process is prevented from leaking through the gap and affecting the life and health of the staff.

[0026] In order to fix and retract the door body 104, an external mechanism 1 is proposed. By setting two pillars 103 and the door body 104, the position of the top plate 102 is fixed by the two pillars 103, and the top of the top plate 102 is fixedly connected with a protective shell 101. The roller installed inside the protective shell 101 is fixed and protected, and the door body 104 is rolled up and opened by the roller. Through holes are opened at the bottom of the top plate 102 and the protective shell 101, and the door body 104 can pass through easily through the through holes.

[0027] Embodiment 2:

[0028] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problem in the prior art that after the lifting door is closed, there is a gap between its surface and the slide rail, the sealing effect is poor, and the acid mist is prone to leakage. However, if the door body 104 directly contacts the sealing strip a204 and the sealing strip b205 during the movement, as the number of movements increases, the door body 104 will wear the sealing strip a204 and the sealing strip b205, which not only reduces the service life of the device, but also affects the sealing effect.

[0029] In order to ensure the service life of sealing strips a204 and b205 and the sealing effect of the device, combined with Figure 1 and Figure 3 as well as Figure 4As shown, soft belts 206 are installed on the door body 104 at positions corresponding to the sealing strips a204 and b205. The material of the soft belt 206 is polytetrafluoroethylene, which is a common sliding material with good self-lubricating effect. The friction caused by the door body 104 to the sealing strips a204 and b205 during the closing and opening process is greatly reduced, thereby ensuring the service life of the sealing strips. At the same time, polytetrafluoroethylene also has good sealing properties, further improving the sealing effect of the device.

[0030] In order to increase the closing speed of the door body 104, a driving mechanism 3 is proposed, which is fixedly connected to the bottom of the fixed plate 208 by a bottom plate 301, and the bottom of the bottom plate 301 is fixedly connected to a protective outer box 303. Both sides of the bottom of the door body 104 are fixedly connected with pull ropes 302, and the two pull ropes 302 both penetrate the fixed plate 208 and the bottom plate 301. Both sides of the top wall of the protective outer box 303 are rotatably connected with reels 304, and one end of the two pull ropes 302 is connected to the center of the reel 304. The inner part of the bottom plate 301 Two micro motors are installed to drive two reels 304 respectively. The positions of the two pillars 103 are fixed by the bottom plate 301. When the door body 104 needs to be closed, the door body 104 is released by the roller shaft, and the two micro motors drive the two reels 304 to rotate, so that the two pull ropes 302 apply a downward force to the door body 104, so that the roller shaft and the reel 304 cooperate with each other, thereby increasing the closing speed of the door body 104 and avoiding a long closing time of the door body 104, which affects the sealing of the acid mist.
