Description
Technical field
The utility model relates to a kind of building hoist, especially relates to a kind of building hoist skylight mechanical interlocks.
Background technology
Cage door skylight is the important component part of building hoist, and because existing construction elevator cage door skylight inside and outside can not be opened by key at cage, skylight also can be moved at the state cage of opening, and therefore has certain potential safety hazard.Chinese patent CN103332546A discloses a kind of cage skylight and cage.Detector switch is arranged on cage and obtains action number by the folding condition of sky window, be that detector switch obtains actuating signal by sky window, for locking lockset and the separate work of detector switch of day window, between lockset and detector switch, without being connected, simplify the structure of day window; Because detector switch works alone, avoid detector switch misoperation, improve the safety performance of elevator.The applicant discloses a kind of construction elevator cage door skylight electromechanical interlocking device in Chinese patent CN202912537U, is provided with travel switch, spring, rotating disk, shift fork, switch enclosure, switch handle, gusset piece and day window; Described travel switch is fixed on gusset piece, and rotating disk is contained in the little rotating shaft of gusset piece and can rotates, and spring connects the rotation direction for controlling rotating disk with rotating disk, and switch enclosure is fixed on day window, and switch handle connects with shift fork by switch enclosure.Described travel switch can be fixed on gusset piece by bolt and nut, and described switch enclosure can be fixed on day window by bolt and nut.Outside cage, can open by switch handle, in cage, need to open with specific key, and only under the state of skylight door locking cage just can move, the safety factor while greatly having improved elevator operation.
Summary of the invention
The purpose of this utility model is to provide a kind of improved building hoist skylight mechanical interlocks.
The utility model is provided with handle, axle sleeve, rubber pad, switch seat, clamp, locking bar, guide plate, cage top board and skylight board; Described switch seat is welded on cage top board, handle upper end is provided with a step, handle lower end is threaded and centre has a tapped bore, axle sleeve is enclosed within on the step of handle and is installed on switch seat, handle is fixed on switch seat, rubber pad is located between axle sleeve and switch seat, and axle sleeve and switch seat produce the switch in rigid frictional influence skylight when preventing that handle from rotating; Locking bar upper end is provided with step cutting pattern, locking bar upper end is threaded, the triangular facet coordinating with triangular key is established in locking bar lower end, locking bar upper end is upward through cage top board, clamp is arranged on the step cutting pattern face of locking bar upper end, the tapped bore butt-joint locking of locking bar upper end threaded section and handle lower end, on cage top board, install on the hole of locking bar and contain a guide plate, ensure the installation site of locking bar, clamp and locking bar can do with handle the rotation of certain angle, clamp just rotatable enter in rectangular groove on switch seat, realize the locking in skylight.
Described switch seat can adopt bending part.
Described handle is fixed on switch seat by nut.
The utility model is made simple, easy to use, can better prevent that NOT operation personnel from opening on skylight to cage top, improves safe handling coefficient, also meets the requirement in GB26557-2011 " cage has the dual-purpose building hoist of people's goods of vertically-guided " simultaneously.
