Abstract
The utility model discloses an elevator counterweight safety device, which is provided with a trigger unit, a control unit and a brake unit. When an elevator is in a maintenance stage, the trigger unit of the elevator counterweight safety device is moved to a preset trigger position by the aid of the control unit so that the trigger unit is in a trigger stage; if an elevator counterweight moves to the trigger position, then the elevator counterweight is stopped on a counterweight guide rail, the counterweight is prevented from continuing to lift or fall to hurt maintenance staff at the top or in a foundation pit, and safety space for maintenance is guaranteed. The elevator counterweight safety device is simple in structure, convenient in operation and capable of guaranteeing personal safety of the maintenance staff reliably.
Description
Technical field
the utility model relates to the Elevator weight sensor safety device.
Background technology
are along with the development in economic development and elevator market; Under the theory of energy-conserving and environment-protective; During increasing architectural design, require elevator to possess than normally to require the little headroom height and the melt pit degree of depth, but often under elevator normal repairing state; Safety control space when having guaranteed not maintenance causes maintainer's personal safety to guarantee.
Summary of the invention
The purpose of
the utility model provides the Elevator weight sensor safety device; Wherein through on the position that guarantees the maintenance survival space, trigger element being installed; Make when Elevator weight sensor moves so far the position; Can be touched stop, thereby the stop elevator car has guaranteed elevator top layer or melt pit maintainer's safety.
are for achieving the above object; The technical scheme that the utility model adopts is: the Elevator weight sensor safety device; The counterweight guide rail that comprises counterweight, can guide said counterweight to go up and down; This safety device also comprises trigger element with triggering state and non-triggering state, can make control unit that said trigger element switches between said triggering state and non-triggering state, the said trigger element that can be in said triggering state touch that stop is said to focusing on the brake unit on the said counterweight guide rail then; Said brake unit is arranged on the said counterweight, and said trigger element is installed in and guarantees that elevator top layer or melt pit have on the position of maintenance survival space.
preferably; Said brake unit comprises the safety tongs that is arranged on the said counterweight, and the said trigger element that the opposite side that said safety tongs comprises first fixture block that is positioned at said counterweight guide rail one side, be positioned at said counterweight guide rail can be done open and close movement with respect to said first fixture block and can be in said triggering state touches to clamp second fixture block of said counterweight guide rail with said first fixture block.
are because the utilization of technique scheme; The utility model compared with prior art has advantage: through trigger element, control unit and brake unit are set; This Elevator weight sensor safety device moves to flip flop equipment in advance on the design-calculated trigger position through control unit when elevator is in service mode, makes trigger element be in the triggering state; If Elevator weight sensor moves to trigger position; Then with the Elevator weight sensor stop on the counterweight guide rail, avoid it to continue and hurt the maintainer of top or pit, ensured the maintenance survival space.This Elevator weight sensor safety device is simple in structure, easy to operate, personal safety that can the reliable guarantee maintainer.
Description of drawings
Accompanying drawing 1 schematically shows trigger element and is in the triggering state for the master of the utility model looks scheme drawing;
accompanying drawing 2 is the schematic top plan view of the utility model, schematically shows trigger element and is in the triggering state.
The specific embodiment
The structure of the utility model is further set forth in
below in conjunction with accompanying drawing.
referring to shown in Fig. 1-2, the Elevator weight sensor safety device, and the counterweight guide rail 2 that comprises counterweight 1, can guide counterweight 1 to go up and down also is provided with trigger element 3, control unit 4 and brake unit 5 on this safety device.Trigger element 3 has triggering state and non-triggering state; It is installed in and guarantees that elevator top layer or melt pit have on the position of maintenance survival space; Control unit 4 can make trigger element 3 between triggering state and non-triggering state, switch; Brake unit 5 is arranged on the counterweight 1, and the trigger element 3 that can be in the triggering state touches then with counterweight 1 stop on counterweight guide rail 2.When elevator normally moves, make trigger element 3 be in non-triggering state through control unit 4; When elevator is in service mode; Through control unit 4 flip flop equipment is moved in advance on the design-calculated trigger position; At this moment trigger element 3 is in the triggering state; If Elevator weight sensor 1 moves to trigger position, then with Elevator weight sensor 1 stop on counterweight guide rail 2, avoid it to continue to go up and down and hurt the maintainer of top layer or melt pit.This Elevator weight sensor safety device is simple in structure, easy to operate, life safety that can the reliable guarantee maintainer.
