Abstract
A leaf door driving force adjusting device comprises a leaf door (1) which is installed on a driving shaft (2). The driving shaft (2) is connected with a driving device. The leaf door driving force adjusting device is characterized in that the driving shaft (2) is connected with one end of a soft belt (3) enabling the leaf door to return to an original position during power failure or stoppage; the other end of the soft belt (3) is connected with one end of a straight spring (4); and the other end of the straight spring (4) is fixed to a tension disc (5) or a rack allowing position adjustment. According to the leaf door driving force adjusting device, the straight spring is used for replacing a torsion spring to match a reset torque curve with a driving torque curve of the leaf door, so that the balance of force born by the leaf door in the driving is facilitated, the reset torsion maintains in a set range throughout, motor driving force is reduced, and a great quantity of energy is saved.
Description
Technical field
The utility model relates to a kind of gate driving device, an especially a kind of ticket checking mechanism fan door actuation techniques, specifically a kind of fan drive force adjustment.
Background technology
As everyone knows, the open and close of two fan doors realized opening and closing of gate passage about the fan door gate machine relied on.Tradition fan door drives the motion of fan door by motor by linkage, adopts torsion spring to produce restoring force the fan door is resetted.As shown in Figure 1.The moment of torsion of fan door is the product of its gravity and center of gravity and axle center deviation distance in the horizontal direction, and at nearly 25 ° of anglec of rotation duration of works, it is the SIN function of an anglec of rotation, as shown in Figure 3.Because linkage was connected with the disengaging of fan door when the gate working method required in the fan door closing process power down or meets object blocks, the fan door relies on torsion spring to reset, the torsion spring moment of torsion that arranges need overcome the moment of torsion of fan door when any operating angle, namely wants to overcome the maximum folding moment of torsion of fan door.And because the moment of torsion that torsion spring produces is a linear change, can't mate the sinusoidal variations curve of moment of torsion, the large answer moment of torsion of its generation need adopt larger torsion motor to drive, and has increased the driving difficulty, has wasted the energy.It does not have governor motion simultaneously, replys moment of torsion and has larger uncertainty, can't accomplish the in batches meticulous maintenance of accurate adjustment.
Summary of the invention
The purpose of this utility model is for using torsion spring as the power of opening door-leaf door under the abnormal condition in the existing fan door drive mechanism, and driving mechanism needs to overcome the unnecessary moment of torsion that torsion spring produces in the normal course of operation, and the change in torque curve of torsion spring can't be complementary with fan door driving torque and causes the large problem of energy waste and debugging difficulty, design a kind of new fan door drive force adjustment that moment of torsion that reseting elasticity produces and a fan driving torque are complementary.
The technical solution of the utility model is:
A kind of fan door drive force adjustment, it comprises fan door 1, fan door 1 is installed on the driving shaft 2, driving shaft 2 links to each other with drive unit, it is characterized in that described driving shaft 2 also be connected with make its outage or during fault with the fan door reset soft with an end of 3, the soft other end with 3 links to each other with an end of straight spring 4, and the other end of straight spring 4 is fixed on the pulling force disk 5 or frame that can adjust the position.
The beneficial effects of the utility model:
The utility model is by acting on behalf of torsion spring with straight spring so that the driving moment curve of reset torque and fan door is complementary, be subjected to equilibrium of forces in the favourable fan door driving process, make the scope that moment of torsion is in a setting all the time of replying, thereby reduced motor-driven power, save mass energy, reliability of operation and stationarity are provided.
Restoring force of the present utility model is easy to adjust, is conducive to Installation and Debugging and maintenance.
The utility model is simple in structure, is easy to realize.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment one.
Shown in Fig. 2,4.
A kind of fan door drive force adjustment, it comprises fan door 1, fan door 1 is installed on the driving shaft 2, driving shaft 2 links to each other with drive unit, described driving shaft 2 also be connected with make its outage or during fault with the fan door reset soft with an end of 3, the soft other end with 3 links to each other with an end of straight spring 4, and the other end of straight spring 4 is fixed on the pulling force disk 5 or frame that can adjust the position.
Embodiment two.
A kind of fan door driving force control method, it may further comprise the steps:
At first, an end of soft band is linked to each other with fan door driving shaft; As shown in Figure 2,
Secondly, the other end of soft band is linked to each other with an end of straight spring, the other end of straight spring is fixed on the pulling force disk of adjustable position, the size of regulating pulling force by regulating straight spring incipient extension length, also but organic frame or other mechanism replace the pulling force disk during implementation, be complementary and the moment of torsion of easy balanced sinusoidal variations thereby make straight spring door leaf-pairing door driving shaft produce one, as shown in Figure 4.That the existing torsion spring of cancellation is used straight spring instead restoring force is provided as key point of the present utility model.
Moment of torsion when the pulling force disk of the varied radius that the utility model can be complementary by design and fan door change in torque function come balance fan door to be in diverse location makes a fan door driving shaft stress balance, and it is stressed and make a concerted effort state as shown in Figure 4.In addition, the utility model also can arrange fan door restoring force size by straight spring incipient extension length is set, to maintain easily the deviation that the straight spring tension variations of modifying factor causes in the maintenance.And the pulling force disk is provided with the elastic force pointer, and the starting force of being more convenient for is regulated.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
