Description

A kind of rigid elevator dragging wire rope circuit wire detecting device

Technical field

This utility model is related to elevators field, specially a kind of rigid elevator dragging wire rope circuit wire detecting device.

Background technology

Elevator wire rope belongs to wear-out part or referred to as consumable accessory in elevator.The wire and strand breaking of elevator rope without Immediately find, traction steel-cable may rupture.Ruptured the elevator of steel wire rope, and equipment and security incident necessarily occur.

With in elevator, great majority are fitted without Detecting broken wires in steel rope device to elevator dragging wire rope existing, This allows for elevator often the accident of steel wire rope fracture suddenly in use.Because elevator service personnel is to sentence by range estimation Disconnected steel wire rope has or not fracture of wire, and fracture of wire is how many.The serious steel wire rope of concentrated wear, is not found, arises that wire cable rupture； Even if being mounted with the elevator of Detecting broken wires in steel rope device, the inspection of these elevator wire rope fracture of wires is to order by all size elevator amount body Make, be suitable for wideless, interchangeability is poor.When being especially used in Retrofit of Elevator, elevator structure multi-size on market, existing steel wire Rope detection means is difficult to adapt to.

Utility model content

The purpose of this utility model is to provide a kind of rigid elevator dragging wire rope circuit wire detecting device, and it can be effective Solve problem present in background technology.

For achieving the above object, this utility model provides a kind of following technical scheme: rigid elevator dragging wire rope fracture of wire Detection means, including seat board, connecting plate, box body, driven disc, bolt, bushing, rotating plate, microswitch and switch base；Described box Body is fixed on seat board by connecting plate；Described driven disc is fixed on box body；Described rotating plate is bolted on seat board On；Described microswitch is fixed on seat board by switch base, and the end thereof contacts with rotating plate.

Further, described bolt and rotating plate junction are provided with pillowcase.

Compared with prior art, the beneficial effects of the utility model are: this rigid elevator dragging wire rope fracture of wire detection dress Put low cost, structure simple and flexible, it is easy to accomplish；When fracture of wire is detected, microswitch can make elevator be run by normal speed It is converted into inspection speed to run, and floor flat bed stops ladder nearby, open the door after putting people, elevator can not start, elevator report fault.

Brief description

Fig. 1 is top view of the present utility model；

Fig. 2 is front view of the present utility model；

Fig. 3 is side view of the present utility model；

In reference: 1. seat board；2. connecting plate；3. box body；4. driven disc；5. bolt；6. bushing；7. rotating plate；8. Microswitch；9. switch base.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work The all other embodiment being obtained, broadly falls into the scope of this utility model protection.

Refer to Fig. 1-3, this utility model provides a kind of a kind of technical scheme: rigid elevator dragging wire rope fracture of wire detection Device, including seat board 1, connecting plate 2, box body 3, driven disc 4, bolt 5, bushing 6, rotating plate 7, microswitch 8 and switch base 9； Described box body 3 is fixed on seat board 1 by connecting plate 2；Described driven disc 4 is fixed on box body 3；Described rotating plate 7 passes through spiral shell Bolt 5 is fixed on seat board 1；Described microswitch 8 is fixed on seat board 1 by switch base 9, and the end thereof contacts with rotating plate 7.

Further, described bolt 5 and rotating plate 7 junction are provided with pillowcase 6.

This utility model is operationally:, by the fracture of wire card of hoist ropes, fracture of wire pulls rotating plate for rotating plate 7 or driven disc 4 Or driven disc 4 swings, thus directly touching disconnected or connecting microswitch 8；Microswitch 8 disconnects elevator normal operation mode, connects Elevator slow running pattern, nearby, floor stops ladder enabling to elevator；After releasing personnel, elevator report fault stops ladder it is impossible to reuse； The complete elevator of personnel inspection to be repaired, changes fracture of wire steel wire rope, after recovering this rigid elevator dragging wire rope circuit wire detecting device, electricity Ladder could normally use；After guaranteeing that elevator wire rope damages, elevator is not normally functioning；Bushing 6 reduces when installing to rotating plate 7 Damage it is ensured that the susceptiveness of rotating plate 7.

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out with multiple changes in the case of without departing from principle of the present utility model and spirit, repair Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
