Abstract

The utility model discloses a safety hook for preventing the vehicle plate used by a lifting-transferring parking equipment from falling off. The safety hook comprises a hook body, a barrier strip, and a barrier pin. The barrier strip is hinged at the anchor portion of the hook body to block the groove of the anchor, and the lower end of the barrier strip is longer than a hook clamp. The barrier pin is used for restricting the moving range of the barrier strip. The safety hook has simple structure, low cost, convenient operation and low failure rate, and can be used for hoister in building industry.

Description

Safety hook

Technical field

The utility model belongs to mechanical field, is a kind of safety hook specifically, applicable to lifting cross sliding type parking equipment and skyscraper elevator etc.

Background technology

To have in the known lifting cross sliding type parking equipment to prevent the fall safe suspension gear of (when being out of order) of ride plate, with the safety that guarantees to park cars.This suspension gear comprises electromagnet, control system and lateral pin.Its principle of work is, after the ride plate rises to specified altitude, and the action of control system control electromagnet, the push-and-pull lateral pin inserts ride plate hole inside, when breaking down, when the ride plate descends, to guarantee the certain height that is suspended on of ride plate safety.This ride plate suspension gear has following shortcoming:

(1) suspension gear is made of electromagnet and control setup thereof, complex structure;

(2) adopt electromagnet to want consumed power;

(3) owing to complex structure, existing actuating unit has control mechanism again, and misoperation easily takes place the fault rate height;

(4) the complex structure parts are many, so cost is higher.

The utility model content

Above-mentioned shortcoming at existing ride plate hang and existence thereof, the purpose of this utility model is to provide a kind of later-model suspension gear---safety hook, this safety hook is simple in structure, easy to use, fault rate is low, has overcome the above-mentioned shortcoming of existing ride plate suspension gear.

Safety hook of the present utility model comprises a coupler body, is hinged with a blend stop that crotch groove mouth can be blocked at the crotch place of coupler body, and bill is longer than in the blend stop lower end.

Described blend stop can be hinged on described coupler body one side.

Two backing pins can be arranged on the described coupler body.

Can there be the pin shaft hole that hangs coupler body described coupler body upper end.

The crotch lower surface of described coupler body can be oblique line or arc.

Described coupler body crotch groove uper side surface can be oblique line or arc.

This safety hook has been compared following advantage with known ride plate suspension gear:

(1) simple in structure, cost is low.

(2) easy to use, fault rate is low.

(3) misoperation can not take place.

(4) do not need consumed power.

(5) range of use is wide, not only can be used for lifting cross sliding type parking equipment, also can be used for

In the elevator of building field or other device.

Description of drawings

Fig. 1 is a safety hook constructional drawing of the present utility model;

Fig. 2 is the right elevation of safety hook shown in Figure 1;

Fig. 3 is the fundamental diagram of safety hook shown in Figure 1;

Fig. 4 is the enlarged drawing of the A portion of Fig. 3.

The specific embodiment

Below in conjunction with accompanying drawing and better embodiment safety hook of the present utility model is described further.

As shown in Figures 1 and 2, safety hook comprises a hook coupler body 1, there is the circular hole 11 that usefulness is installed the coupler body upper end, by a slotted pan head screw 3 and nut 4 blend stop 5 is installed in the crotch place of safety hook coupler body 1 side, a cylinder backing pin 6 that can block blend stop 5 is arranged at the bill position of crotch, a cylinder backing pin 2 is arranged at the coupler body middle part.Blend stop 5 can rotate between backing pin 6 and backing pin 2 around screw 3.The crotch bill lower surface of coupler body 1 is an inclined-plane, and the lower surface of hanging the coupler body crotch groove of safety pin 9 also is the inclined-plane.

As shown in Figures 3 and 4, in multi-storied garage, winch jacking system 7 drives and stops having the ride plate 8 of automobile to rise, safety hook 1 is installed on the horizontal beam, be relatively fixed safety pin 9 on the ride plate along rising on the inclined-plane under safety hook 1 bill with safety hook 1, put safety hook 1 back simultaneously, the blend stop 5 that will stretch out bill when safety pin rises to the bill place is jack-up upwards, safety hook 1 is swung forward, ride plate 8 descends, safety pin 9 on the ride plate 8 just enters in the groove of safety hook 1 crotch, and ride plate 8 is suspended on the safety hook 1.

When putting down ride plate 8, desire makes its rising by jacking system 7 earlier, safety pin 9 was along rising on the inclined-plane on the crotch groove when ride plate 8 rose, while jack-up blend stop 5, blend stop 5 whereabouts rode on the backing pin 6 crotch groove mouth are blocked when ride plate 8 continued rising and surpasses blend stop 5, ride plate 8 falls along blend stop 5 and puts after crowded blend stop 5 of while makes safety hook 1, just safety pin 9 is taken from safety hook 1.

Safety hook not only structure is very simple, and whole use is also very convenient.
