Abstract
The utility model discloses a lever-type belt braking mechanism which comprises a rack, a rotary drum and a belt. The rotary drum is fixed on the rack. The belt is wound on the rotary drum. The lever-type belt braking mechanism further comprises a lever which is a forcing device. The middle of the lever is hinged on the rack. A drive end of the lever is provided with a counter weight. A driven end of the lever is provided with a supporting rod. One end of the belt is connected at the driven end of the lever and the other end of the belt is connected on the supporting rod. The distance between a belt connection point of the lever and a hinge point of the lever is not equal with the distance between a belt connection point of the supporting rod and the hinge point of the lever. A drive end of a pressing lever drives the driven end of the lever and the supporting rod to rotate, two ends of the belt both move to the direction of increasing belt tension, meanwhile a wrap angle is enlarged, friction and a friction area are increased, therefore friction torque between the rotary drum and the belt is increased, the rotary drum gradually stops, non-single-point braking is performed, a moving part, a fixed part and a braking part can be evenly stressed, a braking process is stable and deformation and damage due to fatigue are not prone to occur.
Description
Technical field
The utility model belongs to the technical field of braking device, relates in particular to a kind of Lever type belt arrestment mechanism.
Background technique
Braking device is used for realizing the action that vehicle and other means of transportation or machinery etc. stop or lowering speed, usually adopt the single-point braking now, exist the shortcoming of movement parts, fixed block and brake component discontinuity, make the braking process stationarity poor, related components deforms easily, fatigue damage.
The model utility content
The technical problems to be solved in the utility model provides a kind of Lever type belt arrestment mechanism, makes movement parts, fixed block and brake component stressed evenly, is difficult for deforming.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme: a kind of Lever type belt arrestment mechanism, comprise frame, cylinder and belt, cylinder is fixed on the frame, belt is on cylinder, also comprise the lever as force application device, the middle part of lever is hinged on the frame, the drive end of lever is provided with counterweight, the driven end of lever is provided with pole, one end of belt is connected on the driven end of lever, and the other end is connected on the pole, and the belt tie point is unequal to the distance of lever hinge with a rod epithelium band tie point on the lever.
Compared with prior art, advantage of the present utility model is: during use, and the drive end of depress lever, the driven end and the pole that drive lever are rotated, all move to the direction that increases belt tension at the two ends of belt, and cornerite increases simultaneously, has increased frictional force and friction area, thereby increased the friction torque between cylinder and the belt, cylinder stops gradually, and the non-single-point braking of this kind mode makes movement parts, fixed block and brake component stressed evenly, braking process is steady, is difficult for deforming and fatigue damage.
Further, the drive end of described counterweight and lever is slidingly connected, the convenient adjusting and replacement.
Description of drawings
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
Fig. 1 is the utility model Lever type belt arrestment mechanism embodiment's structural representation.
Embodiment
As shown in Figure 1, a kind of lever 1 formula belt of the utility model 3 arrestment mechanisms, comprise frame, cylinder 2 and belt 3, cylinder 2 is fixed on the frame, belt 3 is on cylinder 2, also comprise the lever 1 as force application device, the middle part of lever 1 is hinged on the frame, the drive end of lever 1 is provided with counterweight 4, the driven end of lever 1 is provided with pole, one end of belt 3 is connected on the driven end of lever 1, and the other end is connected on the pole, and belt 3 tie points are unequal to the distance of lever 1 hinge with rod epithelium band 3 tie point on the lever 1.
When the utility model uses, the drive end of depress lever 1, the driven end and the pole that drive lever 1 are rotated, and all move to the direction that increases belt 3 tension force at the two ends of belt 3, cornerite increases simultaneously, increased frictional force and friction area, thereby increased the friction torque between cylinder 2 and the belt 3, cylinder 2 stops gradually, the non-single-point braking of this kind mode, make movement parts, fixed block and brake component stressed evenly, braking process is steady, is difficult for deforming and fatigue damage.
For a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement, these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
