The hoisting methods of industrial doors are divided into three types: up sliding hoisting, full vertical hoisting and semi vertical hoisting. The torsion spring is installed as follows.
1、 Sliding industrial door:
1. 将门体置于下(即处于关闭状态):将扭簧一端固定，将扭簧另一端缠绕安装所需的匝数，然后将扭簧调整端推至固定端，拧紧调整法兰上的螺丝。扭力弹簧绕组数=门高÷线轮周长+预紧0.5 ~ 1圈。
1. Put the door body down (i.e. in the closed state): fix one end of the torsion spring, wind the other end of the torsion spring around the number of turns required for installation, then push the adjusting end of the torsion spring to the fixed end, and tighten the screws on the adjusting flange. Number of torsion spring windings = door height ÷ circumference of wire wheel + pre tightening 0.5 ~ 1 turn.
2. 将门体置于顶部(即开启状态):将扭力弹簧一端固定，将扭力弹簧沿调节端延长60 ~ 120mm，预紧0.5 ~ 1圈，最后将扭力弹簧的调节端用螺丝固定在轴上。为什么要拉伸扭力弹簧?因为在提升门体的过程中，扭转弹簧的外径会变小，转动次数会增加，因此，弹簧的伸长使其有一定的间隙，便于提升门体。
2. Place the door body at the top (i.e. open state): fix one end of the torsion spring, extend the torsion spring along the adjusting end by 60 ~ 120mm, pre tighten by 0.5 ~ 1 turn, and finally fix the adjusting end of the torsion spring on the shaft with screws. Why do you want to stretch the torsion spring? Because in the process of lifting the door body, the outer diameter of the torsion spring will be smaller, and the number of turns will increase. Therefore, the extension of the spring makes it have a certain gap, which is convenient for lifting the door body.
2. Fully vertical lifting industrial door: because the torsion spring is always the body with even weight of bearing door, only by changing the diameter of grinding wheel, that is to say, changing the torque, in order to balance the torsion spring and door, you need to install tower wheel. The torsion spring installation of the vertical industrial door needs to be pre tightened. The length of the wire rope must be determined according to the wire board of the tower wheel. When the door body is opened to the top, the wire rope goes from the big circle on the tower wheel to the small circle.
3、 Semi vertical lifting industrial door: it is necessary to install a half tower wheel to rebalance the torque of torsion spring with the door. The tower wheel part of the half tower wheel is used for the vertical lifting of the door. The sliding part of the door is lifted together with the plane part of the half tower wheel.
The torsion spring of the semi vertical lifting industrial door also needs to be pre tightened during installation. The winding method of steel wire rope is as follows: firstly, from the big round wheel of the half tower to the small circle, and then continue to cycle the wheel of the flat wheel of the half tower, and the number of turns on the flat wheel is determined according to the part of the body on the sliding door of the lifting height.
