Abstract

The utility model discloses a landing door locking device for elevator maintenance and protection. The device comprises a clamping linkage mechanism and a supporting base. The clamping linkage mechanism comprises a spring, a star type handle, a stud and a non-standard nut. The stud and the star type handle are combined as a whole. The lower end of the stud is provided with threads which are matched with the non-standard nut in a rotating mode, and the relative position of the stud and the non-standard nut can be adjusted through forward and reversing rotation. The supporting base serves as a support, the two side faces are provided with independent symmetric clamping blocks firstly, and then the stud penetrates through the spring, a gasket, an upper side face center hole of the supporting base and the non-standard nut sequentially. The star type handle is rotated, so that the distance between the non-standard nut and the star type handle is reduced; the non-standard nut abuts against the two symmetric clamping blocks due to compression of the spring, and the clamping blocks expand to the outer side of the supporting base. Before the device is used, the spring keeps a certain compression amount, so that the whole device is tensioned. The device has the advantages of being high in operation efficiency, easy, convenient and quick to operate and suitable for most sill devices in the market to lock elevator landing doors.

Description

A kind of layer door lock locking apparatus for elevator maintain and protection

Technical field

The utility model relates to safety locking device, the layer door locking device of using while relating to specifically elevator maintain and protection, safety detection.

Background technology

Elevator maintain and protection and safety detection personnel during to elevator reparing and safety detection, often need to verify the validity of the devices such as elevator door safety switch, car top inspection device, emergency stop device, pit equipment, need personnel to pass in and out frequently layer door.At present, mainly by the miniature devices such as manpower continuous action and similar screwdriver stuck come the open mode of retaining layer door.But this causes repair and maintenance personnel ' s efficiency low on the one hand, is difficult for multi-job operation; The easy disengaging of gadget causes stuck inefficacy and brings potential safety hazard on the other hand.Existing layer door lock locking apparatus, relies on continuous rotating handles to carry out the clamp of spreading both sides, thereby makes clamp side and sill side static friction locking layer door.But this device needs continuous rotating handles clamp and unclamp clamp at every turn, efficiency is very low; Clamp spacing variation range is little, sill width applicability not of uniform size is reduced, and be mainly sill structure design not with the level, because step has affected stressed, thereby general to sill locking effect with the level; Between clamp surface and sill surface, static friction force easily causes layer door to slide not, and rotating handles tunes up gripping power again, but causes device distortion.

Summary of the invention

For shortcoming in above-mentioned existing production technology, the problem that the utility model device will solve is: a kind of disposable adjustment locking or simple setting device of only needing is provided, improves layer door lock and stop efficiency; Improve the commonality of device; Reasonably project organization details, reduces the device distortion that device gripping power brings.That this utility model device possesses is simple and convenient, applicability and the high feature of reliability.

The purpose of this utility model can realize by following measures, and it comprises: star-like handle, spring, double-screw bolt, clamp, non-standard nut, supporting seat, packing ring.Double-screw bolt and star-like handle combination are integral; Double-screw bolt bottom has screw thread to be rotated and to coordinate with nonstandard nut, can positive and negative rotation adjust both relative positions; Supporting seat is as support, and first two sides are provided with symmetrical clamp, and then double-screw bolt successively passes spring, packing ring, supporting seat upper side centre hole and nonstandard nut; Rotate star-like handle, thereby nonstandard nut and star-like handle spacing reduce, spring-compressed makes nonstandard nut that two symmetrical clamps are tightly pushed up to jail, causes clamp to stretching outside supporting seat; Before device uses, spring retains certain amount of compression, whole device tensioning; When device uses, the side of symmetrical clamp is greater than sill width, and when actual use, it,, to the motion of supporting seat medial surface, guarantees that symmetrical clamp and sill side are adjacent to all the time; The power that is adjacent to is adjusted amount of spring compression by nonstandard nut and star-like handle spacing.

Operation logic of the present utility model is as follows: in the time that elevator door navigates to suitable sill position, adjust the utility model; A hand is by firm supporting seat, and a hand is pressed star-like handle Compress Spring, thereby clamp freely unclamps adjustment spacing, utility model is inserted to sill defensive position and decontrol, and clamp self adaptation is pasted firm sill side; If in advance to be adjacent to power inadequate, rotate star-like handle and improve amount of spring compression, make nonstandard nut withstand clamp tightr, clamp further moves to sill side, improves gripping power; The clamp position that this is adjusted, reusable in another same model sill equipment.

The feature of above-mentioned technology is: simple in structurely understand, and operation easily can reach elevator door locking and fixes; Same model sill installed mostly by same community or unit, and the adjustment of last utility model needn't again repeat to rotate star-like handle and adjust gripping power with application; It is large that clamp spacing is transferred amplitude, thereby utility model is applicable to being applied in and comprises with in step sill and the Trapezoidal on a large scale with step sill not.

Such scheme also comprises following characteristics: between described clamp and supporting seat side, have a small amount of gap, thereby guarantee clamp retractable, be beneficial to the installation of utility model; Ridge design processing is carried out on the surface of clamp and sill contacts side surfaces, improve roughness of surface and improve friction coefficient, can relatively reduce contact force, reduce nonstandard nut and withstand clamp power, or be equivalent to reduce amount of spring compression, this all makes utility model stress deformation reduce, and improves service life; The imperfect hole of sidetracking guarantees the gap that double-screw bolt and clamp are large in clamp, makes clamp spacing setting range become greatly.

Further: described nonstandard nut is cylinder side face drilling tapped bore, and tapped bore and double-screw bolt are used in conjunction with; Nonstandard nut is of moderate size, and guarantees that its side can push up firm clamp; Clamped of nonstandard nut blocks, and is beneficial to star-like handle positive and reverse return and transfers adjusting double-screw bolt and nonstandard nut spacing.
