Abstract
The utility model relates to an electric hoist, in particular to an electric hoist with a lever position limiter, which comprises a reel and a break firing position limiter. The utility model is characterized in that the lower end of the break firing position limiter is movably hinged with a rotary rod whose another end is connected with a lever, the top of the rotary rod is connected with the contact of the break firing position limiter, the lower end of the lever through a steel wire is suspended at the lower end of the electric hoist. The utility model resolves the problems of the prior art such as steel wires are easy to arrange disorderly. The electric hoist has the advantages of simple structure, flexible operation, simple installment, safe and reliable position limitation.
Description
Technical field
The utility model relates to a kind of electric block, specifically a kind of electric block with lever inhibiting device.
Background technology
When hoist ceiling crane promotes weight, safety device, just inhibiting device must be installed; hoist ceiling crane all is to utilize rope winding jib to be enclosed within the main tube now; rope winding jib 9 moves with it when reel rotates, and weight is mentioned when outreaching, and rope winding jib 9 drives slide block 8 bump limiting device contacts 7; the compressing contactless switch; make contact open, the motor outage stops to promote; safety guard-safeguard effect (as Fig. 1) is played in the not pulleying of weight that protection is mentioned.In the production process of mine, frequently use this safe inhibiting device to have following three shortcomings:
1, period of service is short: rope winding jib is followed steel cable rotation repeatedly back and forth in main tube, and the steel disc rivet of rope winding jib fractures easily.
2, it is loaded down with trivial details that the rope winding jib of this safe inhibiting device damages the back installation, and skilled installer wants time half a day could change a width of cloth.
3, the slide block of inhibiting device pipe link is loosening easily, causes inhibiting device malfunctioning, easily causes the accident.
Summary of the invention
The purpose of this utility model is exactly the defective at existing product, and a kind of electric block with lever inhibiting device is provided, and it has solved existing hoist ceiling crane and has occurred disorderly row's phenomenon of steel cable generation easily, causes and uses unsafe shortcoming.
The technical solution of the utility model is achieved in that it comprises reel and cutoff device, it is characterized in that: be movably hinged a dwang in the lower end of cutoff device, the other end of dwang is connected with lever, the top of dwang is connected with the contact of cutoff device, and the lower end that steel cable is suspended at electric block is passed in the lower end of lever.
The utility model does not use rope winding jib, steel cable is stressed in reel to be the same with screw rod and nut, all processed the conductor rope groove from 0.5t to 20t hoist ceiling crane reel, just lead angle changes along with promoting specification weight and steel cable, and the conductor rope groove is also changing, produce moment of rotation by motor, the deadweight of suspension hook and steel cable produces the shear force along reel, can be automatically along grooving (lead angle) lifting, and disorderly row's phenomenon can not take place in steel cable.We install mechanical lever (as Fig. 2) additional on circuit fire stop.When hoist ceiling crane when promoting weight near reel, the lever of this device contact with suspension hook, drives the lever upward movement, simultaneously at the effect lower compression circuit fire stop contact of fulcrum, contactless switch is disconnected, motor cuts off the power supply, and reaches spacing safely.
The utility model beneficial effect is simple in structure, and work flexibly, and is easy for installation, and safety is spacing reliable.
Description of drawings
Fig. 1 is the prior art constructions scheme drawing
Fig. 2 is a structural representation of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 2: the utility model comprises reel 1 and circuit fire stop 2, be movably hinged a dwang 3 in the lower end of circuit fire stop 2, the other end of dwang 3 is connected with lever 4, the top of dwang 3 is connected with the contact 7 of circuit fire stop 2, and the lower end that steel cable 5 is suspended at electric block is passed in the lower end of lever 4.
When the electric block energising was started working, suspension hook 6 was when rising near the top, and lever 4 devices are started working, and suspension hook 6 forces lever 4 to drive dwang 3 and clockwise rotates, and dwang 3 is compressed into contact 7, made circuit fire stop 2 outages, and suspension hook 6 stops this rising.The utility model steel cable can not occur disorderly row's phenomenon takes place, so its spacing safety, and is easy to install and use.
