Description

Technical Field

[0001] The invention relates to a torsion spring electric force adding device and method. Background Art

[0002] Flap doors are widely used in garages, passages and other areas due to their excellent safety performance, simple maintenance process, outstanding stability and fast opening speed.

[0003] As one of the important components of the flap door, the torsion spring is used to balance the weight of the movable door panel so that the electric door can work smoothly. When the garage door is closed, the torsion spring will be compressed to store energy; when the garage door is opened, the energy stored in the torsion spring will be released to help the garage door open. The energy storage of the torsion spring is related to the weight of the garage door. If the garage door is heavy, multiple torsion springs are needed to store more energy to open the garage door. Generally speaking, double torsion springs are required if the width of the door opening exceeds 3.3 meters, and the height of the door opening is generally between 3 and 9 meters. For ultra-high garage door coil springs, climbing equipment such as lifting platform trucks is required, which is a very dangerous job.

[0004] During the process of replacing the torsion spring, each torsion spring needs to be coiled at least 9-10 times, which means that the staff needs to manually rotate it 36-40 times. As the torsion spring's power storage continues to increase, the required rotation force also gradually increases, and the pulling force can reach more than 500 kg, which makes the operation more difficult. Therefore, this operation usually requires 2 or more staff members to participate at the same time, and they work in turns to complete it. The time required for the entire replacement process depends on the specific situation, but it is generally between 1 and 2 hours.

[0005] As a consumable material, the torsion spring has a service life. When the torsion spring of the flap door breaks, the garage door will be completely paralyzed and cannot be opened in either electric or manual mode. Therefore, in order to prevent the torsion spring from breaking, it is necessary to replace it in advance before the torsion spring reaches its service life.

[0006] During the process of torsion spring force accumulation, workers face a high risk of mechanical injury. Because the torsion spring itself has a strong elastic force, if it is improperly operated or an accident occurs, it may cause injury to the workers.

[0007] However, in the process of maintenance and replacement of torsion springs, the force application or force release process still adopts the traditional manual operation, which is time-consuming and labor-intensive, with high labor costs and low work efficiency. Summary of the invention

[0008] The present invention solves the problems of high risk, long time consumption and low efficiency in the process of manually replacing torsion springs forcing super-high and super-large flap garage doors, and provides a torsion spring electric energizing device and method.

[0009] The present invention aims to improve safety and efficiency at work, is innovative and popularizable, and can be extended to workplaces containing torsion springs. The present invention provides a new device and method for automatically coiling springs without human intervention by using electricity instead of manual labor.

[0073] The present invention is described in detail below in conjunction with the accompanying drawings:

[0074] The present invention provides an embodiment, see Figure 8 , Fig. 9 , Fig.10 , Fig.16 , Fig.17 , Fig.18 The torsion spring electric booster is used to open the flap garage door. It mainly consists of three parts, including a power device that provides power (such as a winch, an electric or manual winch, a vehicle with a traction function), a fixing device that fixes the torsion spring head, and a traction device (such as a traction belt, a chain, a steel wire rope) wound around the fixing device.

[0075] See also Figure 1a , Figure 1b , the fixing device for fixing the torsion spring head includes a fixing part, a rotating tensioning part, and a tail fixing piece 5;

[0076] See also Figure 2 , the fixed part is composed of an upper half 1 of the fixed part and a lower half 2 of the fixed part;

[0077] See also Figure 3 The rotating and tightening part is composed of an upper half 3 of the rotating and tightening part and a lower half 4 of the rotating and tightening part;

[0078] See also Figure 4 , Figure 5 , Figure 6 , Figure 7 The upper half 1 of the fixed part and the lower half 2 of the fixed part are fixed to the torsion spring head 9 by screws; Figure 7 As shown, an M14 screw 6 is used to fix the torsion spring head;

[0079] The upper half 1 of the fixed part is fixedly connected with the upper half 3 of the rotating tensioning part by screws;

[0080] The lower half 2 of the fixed part is fixedly connected with the lower half 4 of the rotating tensioning part by screws;

[0081] The tail fixing piece 5 is fixed to the rotating tensioning part by screws to play a reinforcing role; Figure 7As shown, M10 screws 8 are used for reinforcement;

[0082] Set a stronger screw on the rotating tension part, such as Figure 7 As shown, an M10 screw 7 is used to fix the traction belt.

[0083] The load-bearing capacity of the selected traction belt should match the needs of torsion spring energy storage, and the corresponding winch specifications and models should also be selected to match it.

[0084] In order to facilitate the movement of the winch, the winch is placed on a movable platform for easy operation.

[0085] In order to obtain the torsion spring electric boosting device of the present invention, the following operations need to be performed:

[0086] Dismantle the waste torsion spring head and conduct reverse engineering measurement and modeling;

[0087] Design a modular removable fastener consisting of five modules to form a fixing device for fixing the torsion spring head; refer to Fig.11 , Fig.12 , Fig.13 , Fig.14 , Fig.15 The fixing device is used to fix the torsion spring head. The fixing device is a torsion spring head fastener, which can be assembled and disassembled, reused, and installed conveniently; the torsion spring head fastener is designed with manual adjustment holes, which can adjust the torsion spring position later, accurately and reliably; the cross-symmetrical fixing design of the torsion spring head fastener can ensure the fastening safety;

[0088] Choose the right traction belt and winch;

[0089] Assemble a movable platform vehicle to carry the winch.

[0090] The present invention provides another embodiment, a method for electrically applying force to a torsion spring, which is a method for applying force or unloading force to a torsion spring using the electrically applied force device for a torsion spring of the present invention;

[0091] The traction device is fixed on the screw on the rotating tensioning part. Under the traction of the power device, the traction device is wound on the rotating tensioning part. When the traction device is wound by the rotating tensioning part, the rotating tensioning part rotates to drive the fixed part to rotate, and the fixed part drives the torsion spring head to rotate, thereby storing energy in the torsion spring. In the reverse direction, the stored energy of the torsion spring will be released.

[0092] The power device can be set as a winch, an electric or manual winch, a vehicle with a traction function, etc., and the traction device can be set as a traction belt, a chain or a wire rope, etc.

[0093] Install the winch or capstan on a movable platform vehicle, fix one end of the traction belt on the screw on the rotating tensioning part, and under the traction of the winch, the traction belt is wound around the rotating tensioning part. When the traction belt is wound around the rotating tensioning part, the rotating tensioning part rotates to drive the fixed part to rotate, and the fixed part drives the torsion spring head to rotate, thereby storing energy and adding force to the torsion spring. When the rotating tensioning part rotates in the opposite direction, the stored energy of the torsion spring will be released, and the torsion spring will be unloaded. According to the weight of the garage door, the number of torsion springs can be adjusted, and multiple torsion springs can be added together to store more energy to open the garage door. No matter how many torsion springs the garage door has, the device of the present invention is used to add force or unload force to the torsion springs one by one. For example, when replacing multiple torsion springs, the fixing device for fixing the torsion spring head of the present invention is installed on all the torsion spring heads that need to be replaced in advance, and the torsion spring electric force adding device of the present invention is used to tighten and add force to the torsion spring and fix the torsion spring, and then the torsion spring electric force adding device of the present invention is removed.

At the same time, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
