Abstract
The utility model provides belongs to the field of manufacturing dragging elevator overspeed protecting device, which relates to a spring controller for dragging brake device of an elevator, comprising a spring, a lock hook and a releasing assembly. The spring controller for dragging brake device of an elevator is characterized in that one end of a connecting arm is connected with a movable braking block, and the other end of the connecting arm is connected with a slide shaft. The lock hook is fixed on a lateral plate of a fixed braking block, and the lateral plate is provided with an arc groove. The lock hook is locked up with the slide shaft. The utility model adopts the lock hook to control a compression spring and makes use of the self-locking function of the lock hook to guarantee the compression spring not be released in free state or in braking state, so the reliability and the safety performance of a braking device is improved. The spring controller for dragging brake device of an elevator also saves an original hydraulic control system of the compression spring, simplifies the structure of the braking device and reduces the manufacturing cost.
Description
Technical field
The utility model belongs to the manufacturing field of towed elevator overspeed protection device, relates to a kind of spring governor of brake device for elevator.
Background technology
In the towed elevator overspeed protection device, be provided with brake shoes, spring, cam and follower, latch hook and releasing unit.When need are realized glancing impact to hoist ropes, discharge control mechanism and be subjected to trigger the release compression spring, the motion of compression spring charge releasing belt moving cam, cam follower drives moving brake shoes and moves joint to deciding brake shoes, at this moment, hoist ropes in the high-speed motion is customized moving liner plate and moving brake liner plate clamping, thereby produces gripping power, the motion of braking hoist ropes.At present, adopt hydraulic pressure to come controlling spring compression and release in the towed elevator overspeed protection device, the control system complexity, and also release needs power supply control.When wanting the big quality of stop, because spring stiffness is very big, spring power by compression is also very big, and the power of HYDRAULIC CONTROL SYSTEM then requires bigger, therefore, can not realize the control to spring easily and safely in fluid control.
Summary of the invention
The purpose of this utility model is to design a kind of spring governor of simple in structure, easy to operate, safe and reliable elevator overspeed brake equipment.
The purpose of this utility model is to reach by the following technical programs: the spring governor of described towed elevator brake equipment, the link arm and the restoring lever that comprise spring, latch hook and releasing unit, connection brake shoes, it is characterized in that link arm one end connects moving brake liner plate, the other end connects a slide shaft; Latch hook is fixed on the side plate of deciding brake shoes, and side plate is provided with deep-slotted chip breaker; Latch hook and slide shaft friction interlocking.
Above-mentioned spring governor, two force application springs of its slide shaft cross-under, slide shaft are subjected to the interior motion of the deep-slotted chip breaker that acts on side plate of restoring lever and link arm.
The latch hook releasing unit of above-mentioned spring governor can be by machinery or electromagnetic mode control.
Spending less than 22 of the latch hook of above-mentioned spring governor and slide shaft from the locking angle.
The utility model adopts latch hook from lock control, utilizes the friction force of latch hook and slide shaft to make spring be in compressive state.The auto-lock function of latch hook guarantees can be under free state and braking mode, and compression spring can not be released, and has improved the reliability and the safety of brake equipment.Simultaneously, the utility model has been save the compression spring hydraulic control system, has simplified the structure of brake equipment, has reduced manufacturing cost, has good economic benefits.

Fig. 3 is the latch hook part sectional view in the utility model.
Wherein: 1-spring, 2-latch hook, 3-releasing unit, 4-slide shaft, 5-deep-slotted chip breaker, 6-link arm, the moving brake shoes of 7-, 8-decide brake shoes, 9-hoist ropes, 10-restoring lever, 11-side plate.
The specific embodiment
Below in conjunction with accompanying drawing embodiment is described in further detail:
The spring governor of towed elevator brake equipment as depicted in figs. 1 and 2.One end of link arm 6 connects moving brake shoes 7, and the other end connects a slide shaft 4; Decide brake shoes 8 and connect latch hook 2 by side plate 11; Latch hook 2 and slide shaft 4 friction interlockings.Spring 1 passes through latch hook 2 from lock control, keep compressive state, when velocity limiter is worked, discharge latch hook 2 by releasing unit 3, the release force of compression spring 1 promotes slide shaft 4 and moves in deep-slotted chip breaker 5, action by link arm 6 drives moving brake shoes 7 to decide brake shoes 8 motions, and two brake shoes engage and hoist ropes 9 is produced gripping powers, reaches the braking purpose of elevator of advancing that exceeds the speed limit.
As depicted in figs. 1 and 2, two force application springs of slide shaft 4 cross-under, slide shaft 4 are subjected to the deep-slotted chip breaker that the acts on side plate 11 5 interior motions of restoring lever 10 and link arm 6.
As shown in Figure 3, when slide shaft 4 interlocking latch hooks 2,4 of latch hook 2 and slide shafts produce friction self-locking power, make compression spring 1 be in compressive state, guarantee that compression spring 1 is not released under elevator operation normal condition.Latch hook 2 is 21.95 degree with slide shaft 4 from the locking angle.
As shown in Figure 3, the interlock of latch hook 2 and releasing unit 3 is controlled by machinery or electromagnetic mode.Minimum release force during according to the latch hook self-locking is determined the point of application, control effort＜250N that the point of application produces.
Claims (4)
