Abstract
The utility model relates to a steel wire rope slacking and fracturing warning device. The warning device comprises a first fixed device and a second fixed device which are fixed to a steel wire rope arranged vertically, a long threaded rod is further arranged between the first fixed device and the second fixed device, and the top end of the long threaded rod is provided with a movable contact; a third fixing device is further arranged on the upper portion of the long threaded rod and provided with a short threaded rod, and the tail end of the short threaded rod is provided with a stationary contact arranged above the movable contact; a gap is formed between the stationary contact and the movable contact, and the stationary contact and the movable contact are respectively connected with a control console through control lines. When the steel wire rope is slacked or fractured by accident, the stationary contact and the movable contact can make contact and trigger a safety protection device of an elevator, or a three-dimensional parking lot or other hoisting equipment to relieve damage caused by accidents. The steel wire rope slacking and fracturing warning device has the advantages of being easy to install and high in sensitivity and finding slacking and fracturing of the steel wire rope timely.
Description
Technical field
The utility model belongs to the technical field of weight-lifting equipment security alarm, particularly a kind of steel wire rope looseness and breaking alarm device.
Background technology
The weight-lifting equipment such as elevator, parking systems is in operational process, substantially be to pull to realize vertical lift by steel rope, in such weight-lifting equipment operational process, as there is the unexpected slack rope of steel rope or fracture, due to hoistway sealing, can not find in time, may cause the loss that cannot retrieve; Although this kind equipment has generally all been equipped band brake apparatus, this device can not work in the unexpected moment occurring at once, while by the time working, may have an accident.Therefore, be necessary to design a kind of steel wire rope looseness and fracture alarm safety device, in the time that accident occurs, brake in time the weight-lifting equipment such as elevator, parking systems, will contribute to reduce such equipment breakdown incidence.
Utility model content
Technical problem to be solved in the utility model is, a kind of steel wire rope looseness and breaking alarm device are provided, and while there is unexpected slack rope or fracture, reports to the police and brakes the weight-lifting equipment such as elevator, parking systems for steel rope, installs simple, highly sensitive.
The utility model is to realize like this, a kind of steel wire rope looseness and breaking alarm device are provided, comprise two the first anchor fitting and the second anchor fittings that are fixed on vertically disposed steel rope, between the first anchor fitting and the second anchor fitting, be also provided with long bolt, long bolt lower end is fixed on the second anchor fitting, its upper end and the first anchor fitting are actively coupled, and on the top of long bolt, are provided with moving contact; Above long bolt, be also provided with the 3rd anchor fitting, the 3rd anchor fitting is also fixed on steel rope; On the 3rd anchor fitting, be provided with short screw, on the tail end of short screw, be provided with break back contact, break back contact is arranged on the top of moving contact; Between break back contact and moving contact, be provided with gap, break back contact and moving contact are connected by control line and control desk respectively.
Further, long bolt is fixed on the second anchor fitting by nut.
Further, short screw is fixed on the 3rd anchor fitting by nut.
Further, between moving contact and long bolt, adopt thread connection.
Further, between break back contact and short screw, adopt thread connection.
Further, be provided with convex shoulder on long bolt, convex shoulder is positioned at the top of the first anchor fitting, is socketed with spring on long bolt, and spring arranges between convex shoulder and the first anchor fitting.
Further, on the first anchor fitting, be provided with shrinkage pool, one end of spring is positioned at shrinkage pool.
Compared with prior art, steel wire rope looseness of the present utility model and breaking alarm device, long bolt and short screw are set on steel rope, at long bolt and the adjacent both ends of short screw, break back contact and moving contact are set, break back contact and moving contact are connected with control desk again respectively.When normal use, between break back contact and moving contact, be provided with gap.In the time that unexpected slack rope or fracture appear in steel rope, break back contact and moving contact can contact and trigger the safety guard of the weight-lifting equipment such as elevator, parking systems, alleviate the infringement that contingency causes.The utlity model has and install simply, when steel rope generation slack rope and fracture, find early the features such as sensitivity height.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model one preferred embodiment.
The specific embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to shown in Fig. 1, the preferred embodiment of the utility model steel wire rope looseness and breaking alarm device, comprise that the first anchor fitting 2, the second anchor fitting 3 and the 3rd anchor fitting 4, the first anchor fittings 2 that are fixed on vertically disposed steel rope 1 are arranged between the second anchor fitting 3 and the 3rd anchor fitting 4.
Between the first anchor fitting 2 and the second anchor fitting 3, be also provided with long bolt 5, long bolt 5 lower ends are fixed on the second anchor fitting 3, and its upper end and the first anchor fitting 2 are actively coupled.On the top of long bolt 5, be provided with moving contact 6.Between moving contact 6 and long bolt 5, adopt thread connection.
The 3rd anchor fitting 4 is fixed on the top of long bolt 5, on the 3rd anchor fitting 4, is provided with short screw 7, is provided with break back contact 8 on the tail end of short screw 7, and break back contact 8 is arranged on the top of moving contact 6, between break back contact 8 and short screw 7, adopts thread connection.Between break back contact 8 and moving contact 6, be provided with gap, break back contact 8 and moving contact 6 are connected by control line 9 and control desk (not shown) respectively.Can, by regulating the position of the 3rd anchor fitting 4, to control two gaps between contact, improve or reduce device sensitivity.Or the position of adjusting short screw 7, to control two gaps between contact, improves or reduces this device sensitivity.
In the time that equipment drives steel rope 1 to work, by relaxing in tensioning process, steel rope 1 will have certain elongation, and the spacing between the first anchor fitting 2 and the second anchor fitting 3 is increased.Compression is simultaneously assemblied in the spring 12 between the first anchor fitting 2 and convex shoulder 11, and the distance between break back contact 8 and moving contact 6 is elongated.
In the time there is the emergency case such as steel rope 1 slack rope or fracture, steel rope 1 sudden contraction of tensioning, reduces the pulling force between the first anchor fitting 2 and the second anchor fitting 3, and therefore spring 12 resiliences are extended, and moving contact 6 is contacted with break back contact 8.After two contact contacts, produce induced signal, to control desk, trigger safety guard by control line 6 transmission of signals.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
