Description
Technical field
The utility model relates to elevator technology field, the safe shift mechanism of especially a kind of home lift.
Background technology
Elevator safety clamp device is under the manipulation of velocity limiter, when elevator speed surpasses the limited speed that elevator governor is set, or fracture occurs and lax in the situation that at suspension strop, by the urgent stop of car and be clamped in a kind of safety device on guide rail.It provides actv. protective effect to the safe operation of elevator, is generally arranged on car frame or counterweight frame.Safety tongs is divided into one-way safety pincers and bidirectional safety tongs.Along with the proposition that car up-running over-speed protection requires, at present, bidirectional safety tongs has use more widely.
In prior art; conventional protection device for over-speed ascending for elevator; the relevant shift mechanism having is installed on elevator cage bottom and carries out linkage work; the safety tongs of some employings left and right sides is only single stretching structure; single stretching structure discontinuity; the braking of its safety tongs lengthens or causes elevator left and right to roll apart from meeting, has reduced the function of safety protection of safety tongs device.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of home lift rational in infrastructure safe shift mechanism, thus the safety that has improved elevator, the safety misadventure that actv. has avoided elevator overspeed descending to cause.
The technical scheme that the utility model adopts is as follows:
The safe shift mechanism of a kind of home lift, the structure of shift mechanism is: comprise lifting rod, one end of described lifting rod is provided with velocity limiter and lifts frame, and described lifting rod middle part is symmetrically installed with reset switch frame, is positioned on the lifting rod of reset switch frame outer end, safety tongs to be also installed and to lift frame; Described shift mechanism is installed on Knapsack-rack, and described knapsack is put up " L " shape structure, on the curb girder of described Knapsack-rack, has hole, and described lifting rod is through institute's perforate.
Further improvement as technique scheme:
Reset switch is installed on the top of described reset switch frame, and the bottom of described reset switch frame connects retracing spring one end, and the other end of described retracing spring is connected on curb girder;
Described safety tongs lifts chord position in the outside of curb girder, and described safety tongs lifts safety tongs is installed on frame;
Described velocity limiter lifts frame and installs by steel rope and overspeed preventer device interlock, described steel wire penetrating Knapsack-rack;
On the steel wheel of described overspeed preventer device bottom, tightening device is installed;
On described Knapsack-rack, diversion sheave component is installed.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, reasonable, easy and simple to handle, stability, the safety that can effectively improve elevator.
While the utility model and UKS switch gearing, during mechanical mechanism action, UKS switch also can move, and disconnects its safety return circuit switch, and electric control system is carried out elevator stoppage in transit protection.Actv. has guaranteed the function of safety protection of safety tongs device.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the safe shift mechanism of home lift of the present embodiment, the structure of shift mechanism is: comprise lifting rod 6, one end of lifting rod 6 is provided with velocity limiter and lifts frame 11, lifting rod 6 middle parts are symmetrically installed with reset switch frame 13, are positioned on the lifting rod 6 of reset switch frame 13 outer ends, safety tongs to be also installed and to lift frame 12; Shift mechanism is installed on Knapsack-rack 3, and 3 one-tenth " L " shape structures of Knapsack-rack, have hole on the curb girder 4 of Knapsack-rack 3, and lifting rod 6 is through institute's perforate.
Reset switch 7 is installed on the top of reset switch frame 13, and the bottom of reset switch frame 13 connects retracing spring 14 one end, and the other end of retracing spring 14 is connected on curb girder 4.
Safety tongs lifts the outside that frame 12 is positioned at curb girder 4, and safety tongs lifts safety tongs 8 is installed on frame 12.
Velocity limiter lifts frame 11 and installs by steel rope 2 and overspeed preventer device 1 interlock, and steel rope 2 is through Knapsack-rack 3.
On the steel wheel of overspeed preventer device 1 bottom, tightening device 9 is installed.
Diversion sheave component 5 is installed on Knapsack-rack 3.
UKS switch (not shown in FIG.) is installed on lifting rod 6.
In actual use procedure, after the utility model installs, UKS switch (not shown in FIG.) is connected safety return circuit line source.When elevator overspeed descending, overspeed preventer device 1 action that exceeds the speed limit, the shift mechanism that interlock is installed simultaneously carries out linkage work, safety tongs 8 is lifted to brake to be fixed on lift car, UKS switch (not shown in FIG.) on shift mechanism cuts out simultaneously, safety return circuit disconnects, and lift car is out of service.Its functional reliability is good, safe.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
