The purpose of this utility model can also adopt following technical measures to solve:
As a kind of scheme more specifically, the corresponding limitation travel switch button of described mounting base side is other to be provided with anchor shaft, and anchor shaft and turning handle lower end are rotationally connected.
Described turning handle upper end is provided with wheel shaft, and foreign steamer is rotationally connected by bearing and wheel shaft.
Described supporting member is angle steel, and angle steel is weldingly fixed on the mounting base surface, and the corresponding push rod of angle steel one side is provided with perforate; Push rod is screw rod, and the perforate that spiro rod rear end passes angle steel is connected with a setting nut, and screw front end is connected with turning handle by an adapter shaft, and spring housing is located at outside the screw rod.
The beneficial effects of the utility model are as follows:
(1) this kind of elevator Anti-over-hoisting device is by the button touching of driver train and limitation travel switch, in the elevator motion process, the foreign steamer that is driver train contacts with the guide rail bracket tooth bar back side, be connected by bearing between the turning handle of foreign steamer and driver train, realize good normal-running fit, damage probability is less; And the roller that is used in the limitation travel switch in the swing arm of its button of touching can be not for a long time and guide rail bracket tooth bar frictional fit, thereby the prolongation travel switch life-span is more safe and reliable;
(2) Anti-over-hoisting device is connected with the transmission device top of elevator by mounting base, its have easy for installation, accuracy of positioning is high, adjust efficiently advantage.
Description of drawings
Fig. 1 is that the utility model Anti-over-hoisting device uses the status architecture scheme drawing.
Fig. 2 is that the A-A of Fig. 1 analyses and observe and the structure for amplifying scheme drawing.
Fig. 3 is Anti-over-hoisting device plan structure scheme drawing.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1 to Figure 3, this elevator Anti-over-hoisting device, comprise mounting base 10 and limitation travel switch 8, described limitation travel switch 8 is fixedly installed on mounting base 10 surfaces, mounting base 10 surfaces also are provided with the driver train of the button of touching limitation travel switch 8, this mechanism comprises turning handle 16, push rod, spring 3 and foreign steamer 14, foreign steamer 14 rotates the upper end that is arranged on turning handle 16, turning handle 16 lower ends and mounting base 10 are rotationally connected, and be positioned at by the limitation travel switch 8 button sides, mounting base 10 surfaces are provided with supporting member, push rod is undertaken on the supporting member, the corresponding supporting member of pusher table face the place ahead is provided with baffle plate 2, spring 3 is arranged between baffle plate 2 and the supporting member, and the push rod front end is connected with the stage casing of turning handle 16.
The other anchor shaft 11 that is provided with of described mounting base 10 corresponding limitation travel switch 8 button sides, anchor shaft 11 is rotationally connected with turning handle 16 lower ends.
Described turning handle 16 upper ends are provided with wheel shaft 1, and foreign steamer 14 is rotationally connected by bearing 12 and wheel shaft 1.
Described supporting member is angle steel 4, and angle steel 4 is weldingly fixed on mounting base 10 surfaces, and the corresponding push rod of angle steel 4 one sides is provided with perforate; Push rod is screw rod 5, and the perforate that angle steel 4 is passed in screw rod 5 rear ends is connected with a setting nut 6, and screw rod 5 front ends are connected with turning handle 16 by an adapter shaft 15, and spring 3 is set in outside the screw rod 5.
