Abstract
The utility model discloses an elevator rope slack protecting device, which comprises a safety switch (1), a rotating shaft (7), and an actuating component which is capable of rotating around the rotating shaft (7); the actuating component comprises a rope hitch push part which is correspondingly matched with the rope hitch (5) and pushed by the rope hitch (5) when an elevator rope is abnormal and the rope hitch (5) rebounds under the action of an internal spring, and a switch trigger part which is correspondingly matched with the safety switch (1) and triggers the safety switch (1) to work when the rope hitch (5) pushes the actuating component to rotate; when the rope is normal, the switch trigger part keeps a distance from the safety switch (1). The safety switch (1) is arranged on a rope hitch plate (6) by a support plate (2). The elevator rope slack protecting device is safety and reliable, and can stop an elevator from working upon slack and other danger produced by the breakage or abnormal extension of the elevator rope; and in addition, the elevator rope slack protecting device has simple structure, is convenient to process, has low cost, and is good for promotion.
Description
Technical field
The utility model relates to a kind of elevator rope creep protection device.
Background technology
Elevator industry develop rapidly in recent years, people also constantly improve the safety requirements of elevator, when elevator wire rope take place to disconnect or during the steel rope abnormal elongation causes unsafe condition such as loosening, should effectively stop elevator to move under this class situation, this is directly connected to the in-use performance of elevator and passenger's the security of the lives and property.
At present, existing elevator rope creep protection device also exists structure comparatively complicated, processing and manufacturing cost height, and on-the-spot the adjustment installed difficulty, the not high shortcomings of reliability.
The utility model content
The purpose of this utility model is: a kind of elevator rope creep protection device is provided, and it is safe and reliable, when elevator wire rope take place to disconnect or during the steel rope abnormal elongation causes unsafe condition such as loosening, can stop elevator to move under this class situation; And simple in structure, processing and fabricating is convenient, and cost is low, is beneficial to popularization.
The technical solution of the utility model is: a kind of elevator rope creep protection device, the actuating member that it comprises safety switch, turning cylinder, the moving axis that can rotate rotates; Described actuating member includes: be provided with the fag end corresponding matching, when elevator wire rope takes place to disconnect or the steel rope abnormal elongation, when fag end rebounds under the effect of self spring, can be promoted the position by the fag end that fag end promotes, and be provided with the safety switch corresponding matching, when fag end pushing action member rotates, the switch triggering position that can trigger safety switch and safety switch is moved; When elevator wire rope just often, switch triggering position and safety switch keep the distance.
Below technique scheme is further described:
Described safety switch is installed on the rope hitch plate by supporting plate.
Because the deadweight of actuating member, generally actuating member is in to the fag end prescription to the trend of rotating.But described supporting plate includes the limit movement member to the restriction site of fag end prescription to rotation.So, keep stable.
Described actuating member comprises interconnected first action plate and second action plate, and described fag end promotes the position and is arranged at second action plate, and described switch triggering position is arranged at first action plate.
Connect by fastener between described first action plate and second action plate.
Described fastener is a screw-nut.
The utility model has the advantages that:
1, elevator rope creep protection device of the present utility model is safe and reliable, when elevator wire rope take place to disconnect or during the steel rope abnormal elongation causes unsafe condition such as loosening, can stop elevator to move under this class situation; And simple in structure, processing and fabricating is convenient, and cost is low, is beneficial to popularization.
2, elevator rope creep protection device of the present utility model, the relative position of safety switch and supporting plate, the relative position of first action plate and second action plate is adjustable, can carry out scene adjustment, assurance function.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a structural representation of the present utility model (overlooking).
Wherein: 1 safety switch; 2 supporting plates; 3 first action plates; 4 second action plates; 5 fag ends; 6 rope hitch plates; 7 turning cylinders.
The specific embodiment
Embodiment: as shown in Figure 1 and Figure 2; a kind of elevator rope creep protection device; the actuating member that it comprises safety switch 1, supporting plate 2, turning cylinder 7, the moving axis 7 that can rotate rotates; actuating member comprises that first action plate 3 and second action plate, 4, the first action plates 3 and second action plate 4 adopt screw-nut to couple together.
Safety switch 1 is installed on the rope hitch plate 6 by supporting plate 2.Also include the limit movement member on the supporting plate 2 to the restriction site of fag end 5 prescriptions to rotation.
Second action plate 4 and fag end 5 corresponding matching settings, when elevator wire rope takes place to disconnect or the steel rope abnormal elongation, when fag end 5 rebounded under the effect of self spring, second action plate 4 can be promoted by fag end 5.
When elevator wire rope just often, second action plate 4 keeps the distance with fag end 5, first action plate 3 keeps the distance with safety switch 1.
In the utility model, each several part size, quantity can require to make, install according to reality.
During use, under general state, because the deadweight of second action plate 4, interlock first action plate 3 moving axis 7 that rotates rotates, and the restriction site that is in supporting plate 2 right-hand members blocks first action plate 3, keeps common state.
When steel rope takes place loosening or disconnects, because load reduces suddenly, fag end 5 upwards bounce-back under the effect of self spring, promote second action plate 4, rotate moving axis 7 of interlock first action plate 3 rotates, and triggers safety switch 1 action then, realizes relevant actions such as towing machine braking.
Should be pointed out that for the utility model also to have the embodiment of multiple conversion and remodeling, be not limited to the specific embodiment of above-mentioned embodiment through proving absolutely.The foregoing description is as just explanation of the present utility model, rather than restriction.In a word, protection domain of the present utility model should comprise those conspicuous to those skilled in the art conversion or substitute and remodeling.
