Abstract
The utility model discloses an improved crane brake controller, which comprises a control circuit provided with brake contactors, wherein the number of the brake contactors is two, main contacts of the two brake contactors are mutually connected in series, and secondary loop coils of the two brake contactors are mutually connected in parallel. The improved crane brake controller has a simple structure, the brake reliability of the crane brake can be greatly improved, and the use is convenient.
Description
Technical field
The utility model belongs to the hoisting crane braking force control system, particularly improved crane brake control setup.
Background technology
At present than the hoisting crane of big elevating capacity owing to consider that traveling comfort adopts frequency control or ac voltage regulator more.Therefore drg to open with band-type brake be to provide electric signal by frequency conversion or ACVV system inside to control the state that a cooresponding brake contactless switch is realized the control brake device.For the smelting driving that steel plant use, owing to want handling liquid ladle, therefore the electrical operation performance of driving is particularly important.There are two cover drgs in every the brake equipment mechanism that hoists of producer's design and construction, but has only a brake contactless switch; In case main contact adhesion or jam appear in the brake contactless switch can't reset fault the time, the normally closed brake equipment is in normally open the falling accident that glides will occur, and consequence is very serious.
Summary of the invention
The purpose of this utility model is to provide a kind of improved crane brake control setup, and it is simple in structure, can improve the braking reliability of crane brake greatly, and is easy to use.
The purpose of this utility model is to realize like this, a kind of improved crane brake control setup, comprise the control circuit that the brake contactless switch is installed, said brake contactless switch is two, the main contact of two brake contactless switchs is cascaded mutually, and the secondary circuit coil of two brake contactless switchs is together parallel with one another.
The utility model adopts two brake contactless switchs, that utilizes that the differences of two contactless switch replacement cycles well avoided the electric elements design action frequency and driving electric elements in service movingly does the contradiction that number of times can't be added up, reduce the separate unit contactless switch because of the probability that mechanism's jam or main contact adhesion can't reset, do not influenced original design-calculated science.Two brake contactless switch master current supply circuits adopt series connection, and the secondary circuit coil adopts parallel way, can only make pig-tail wire and not change original control system, not limited by space environment simultaneously.This device can improve the reliability of the braking of special equipment, reduces the probability of slide hook and downslide accident well; Avoid the requirement of electric elements action frequency and the action unreliability that element mechanical wear is brought.The utility model is simple in structure, can improve the braking reliability of crane brake greatly, and is easy to use.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a connection structure scheme drawing of the present utility model.
The specific embodiment
A kind of improved crane brake control setup, as shown in Figure 1,4 is three-phase alternating current motor among the figure, this control setup comprises the control circuit that brake contactless switch 5 is installed, said brake contactless switch 5 is two, main contact K1, the K2 of two brake contactless switchs 5 are cascaded mutually, and the secondary circuit coil 2,3 of two brake contactless switchs 5 is together parallel with one another.The opening of drg provides 5 actions of two brake contactless switchs of electric signal control with band-type brake by frequency conversion or ACVV system 1 inside and finishes.Adopt the connection structure of two brake contactless switchs of the utility model, can improve the braking reliability of crane brake greatly, easy to use.
