Abstract
The utility model discloses a crane brake protecting system capable of preventing the fault of a band brake contactor from causing hook-releasing accident. The crane brake protecting system comprises the band brake contactor which is connected on a main circuit in series; and the main circuit is connected with at least two band brake contactors in series. The main circuit is connected with at least two band brake contactors in series, when one of the band brake contactors fails, the main circuit can be cut off by other band brake contactors, thus effectively avoiding the hook-releasing accident caused by faults of the band brake contactors.
Description
Technical field
The utility model relates to hoisting crane braking protection system.
Background technology
The potential safety hazard of hoisting crane when work maximum is slipped hook exactly.The major cause that causes slide hook accident is band-type brake contactless switch fault, and is bonding such as the main contactor of band-type brake contactless switch, or iron core blocks or the like.Because the band-type brake contactless switch is connected on the major loop, in case can't disconnect, will causes drg when this releases, can't cut off the power supply and cause that band-type brake can't discharge, thereby cause slide hook accident because of band-type brake contactless switch fault causes major loop.
The utility model content
The technical matters that the utility model solved is: provide a kind of preventing to cause slipping the hoisting crane braking protection system of hook accident because of band-type brake contactless switch fault.
The technical scheme that solves the problems of the technologies described above is: hoisting crane braking protection system, comprise the band-type brake contactless switch that is connected on the major loop, and be connected with at least two band-type brake contactless switchs on the described major loop.
Further be that the actuating device in described at least two band-type brake contactless switchs is connected in parallel on the control loop.
The beneficial effects of the utility model are: at least two band-type brake contactless switchs of polyphone on major loop, after one of them band-type brake contactless switch fault, can disconnect major loop by remaining band-type brake contactless switch, thereby actv. is avoided causing slipping the hook accident because of band-type brake contactless switch fault.Actuating device in described at least two band-type brake contactless switchs is connected in parallel on the control loop, makes the synchronization action of each band-type brake contactless switch, both be convenient to operation, do not change original control system simultaneously by this control loop.
Description of drawings
Fig. 1 is the scheme drawing of major loop in the application's hoisting crane braking protection system.
Fig. 2 is the scheme drawing of control loop in the application's hoisting crane braking protection system.
Be labeled as among the figure: band-type brake contactless switch 1, band-type brake contactless switch 2, actuating device 10, actuating device 20.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Embodiment
Hoisting crane braking protection system as shown in Figure 1 is connected with two band-type brake contactless switchs on major loop, be respectively band-type brake contactless switch 1 and band-type brake contactless switch 2.After one of them band-type brake contactless switch fault, can disconnect major loop by another band-type brake contactless switch, thereby actv. is avoided causing slipping the hook accident because of band-type brake contactless switch fault.As Fig. 2, actuating device 10,20 in these two band-type brake contactless switchs 1,2 is connected in parallel on the control loop, thereby directly control actuating device 10,20 in these two band-type brake contactless switchs 1,2 simultaneously by this control loop, make actuating device 10,20 synchronization actions, thereby these two band-type brake contactless switchs 1,2 are disconnected simultaneously or connect.When one of them band-type brake contactless switch fault, do not influence the work of another band-type brake contactless switch.The above-mentioned structure that actuating device in two band-type brake contactless switchs 1,2 10,20 is connected in parallel on the control loop both had been convenient to operation, did not change original control system simultaneously.
Claims (3)
