Description

TECHNICAL FIELD

[0001] The utility model relates to a torsion spring electric force adding device. BACKGROUND

[0002] The turnover door is widely applied in the garage, the passageway and the like because of its excellent safety performance, simple maintenance process, excellent stability and fast opening speed.

[0003] The torsion spring is one of important components of the turnover door, and the function is to balance the weight of the movable door plate, so that the electric door can work stably. When the garage door is closed, the torsion spring is compressed to store energy. When the garage door is opened, the energy stored in the torsion spring is released to help the garage door open. The energy stored in the torsion spring is related to the weight of the garage door. If the garage door is relatively heavy, multiple torsion springs are needed to store more energy to open the garage door. Generally, double torsion springs are needed when the door width is more than 3.3 meters, and the door height is generally 3 to 9 meters. For the torsion spring of the super-high garage door, a climbing equipment such as a lifting platform vehicle is needed, which is a very dangerous work.

[0004] During the replacement of the torsion spring, each torsion spring needs to be wound at least 9-10 turns, which means that the operator needs to rotate 36-40 times manually. As the torsion spring accumulates more and more energy, the required rotating force gradually increases, and the pulling force can reach more than 500 kg, which makes the operation more difficult. Therefore, this operation usually needs 2 or more workers to participate simultaneously in an alternating manner. The time required for the whole replacement process varies depending on the specific situation, but is generally between 1 and 2 hours.

[0005] The torsion spring is a consumable material with a service life. When the torsion spring of the turnover door breaks, the garage door is in a complete paralysis state, and cannot be opened in either electric or manual mode. Therefore, to prevent the torsion spring from breaking, the torsion spring needs to be replaced before it reaches the service life.

[0006] During the energy storage process of the torsion spring, the operator faces a high risk of mechanical injury. Because the torsion spring itself has strong elasticity, if the operation is not proper or an accident occurs, the operator may be injured.

[0007] However, the force adding or unloading link in the process of replacing the torsion spring during maintenance still uses traditional manual operation, which is time-consuming and labor-intensive, has high labor cost and low work efficiency. SUMMARY

[0008] The utility model solves the problems of high risk, long time consumption and low efficiency in the process of replacing the torsion spring and adding force manually for the super-high and super-large turnover garage door, and provides a torsion spring electric force adding device.

[0009] The utility model discloses a new device and method for automatically spring force loading by using electric power instead of manual work without human intervention.
