Abstract
The utility model discloses a band-type brake non-electric switch-on system for an elevator. The band-type brake non-electric switch-on system comprises a motor band-type brake and a motor unit. The motor band-type brake and the motor unit are connected with an external power source; the motor band-type brake is connected with an electric storage unit which is connected with the external power source; a switch-on operating box is arranged between the electric storage unit and the motor band-type brake. Since the electric storage unit such as an uninterrupted power supply is added, the band-type brake of the elevator can be switched on normally even when a construction site is in power interruption suddenly, the elevator can run to the ground slowly, and safety in operation of the elevator and safety of construction staff are guaranteed.
Description
Technical field
The utility model belongs to elevator field, is specifically related to a kind of elevator nothing and establishes band-type brake system by cable.
Background technology
Along with the high speed development of national economy, building hoist starts bringing into play huge effect at increasing building field, also to apply some special functions in some special places, but, due to the continuous progress of production level, in order to boost productivity, economize labor time, properity, the safety performance of people to elevator requires also more and more higher.
In engineering construction, universal gradually along with mechanization, building hoist has also occupied irreplaceable status in this field, till now, also moving to maturity gradually of the technology of building hoist.Wherein, people are also more and more higher to the safety requirements of building hoist, and due to the environment for use complexity of building hoist, in the use of building hoist, safety is thing of paramount importance; Sometimes building site power failure tripping operation burns out power equipment supply, and that is also normal thing, if elevator now also in aloft work with regard to danger close, although now operating personal can be by manually drawing band-type brake to allow elevator slowly slide to ground, but safe not after all in the operation of cage top, particularly in the time that cage is little, the operational space on cage top also can be restricted, and brings numerous inconvenience.
A kind of pair of source brake control system disclosed in Chinese utility model patent CN203143859U specification sheets; Comprise: programmable logic controller (PLC) PLC, relay (KA4), the first contactless switch (KM41), the second contactless switch (KM42), rectifier (U), thermal relay (4KCE), band-type brake coil (1), described programmable logic controller (PLC) PLC connects described relay (KA4), described relay (KA4) connects described the second contactless switch (KM42), and one group of open contact of described the second contactless switch (KM42) connects described the first contactless switch (KM41); The input end of described rectifier (U) connects another group open contact of described the second contactless switch (KM42), and the mouth of described rectifier (U) connects one group of open contact of described the first contactless switch (KM41); Described thermal relay (4KCE) connects described the first contactless switch (KM41); Described band-type brake coil (1) connects described thermal relay (4KCE).In the time of unexpected power failure, described double embrace brake system is also difficult to play a protective role.
Utility model content
Have a power failure when the aloft work for solving existing building hoist suddenly, need to be with manually drawing band-type brake to allow elevator slowly slide to ground, because the problem of making troubles is limited in the operational space on cage top, and increasing the safety performance of existing band-type brake system, the utility model provides a kind of elevator with without establishing band-type brake system by cable.
Described a kind of elevator is established band-type brake system by cable by nothing, comprise motor internal contracting brake and group of motors, described motor internal contracting brake is connected an external power supply with group of motors, and described motor internal contracting brake connects a power storage unit, described power storage unit connects external power supply, and described external power supply connects Lighting Control Assembly.
Preferably, between described power storage unit and motor internal contracting brake, be provided with out and embrace operating case.
More preferably, described power storage unit is uninterrupted power supply (UPS).
Further, described uninterrupted power supply (UPS) connects Lighting Control Assembly.
The utility model is by the memory cell that increases electric power, even such as uninterrupted power supply (UPS) actv. has ensured the unexpected power-off in building site in the situation that, still can ensure that elevator can leave band-type brake normally, thereby can make elevator can walk to slowly on the ground, ensure the safety of elevator operation and workmen's safety.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to figure 1, described a kind of elevator is established band-type brake system by cable by nothing, comprise motor internal contracting brake 4 and group of motors 5, described motor internal contracting brake 4 is connected an external power supply 1 with group of motors 5, described motor internal contracting brake 4 is opened an armful operating case 3 by one and is connected a uninterrupted power supply (UPS) 2, described uninterrupted power supply (UPS) 2 connects external power supply 1, and described uninterrupted power supply (UPS) 2 is connected Lighting Control Assembly 6 with external power supply 1 simultaneously simultaneously.
In the time of normal operation, external power supply 1 is given uninterrupted power supply (UPS) 2 storage of electrical energy on the one hand, and the electric power of the normal operation of elevator is provided on the other hand, and as the operation of group of motors 5, the Lighting Control Assembly 6 of elevator moves required electric power etc.When external power supply 1 is during because of fault power-off, uninterrupted power supply (UPS) 2 can provide a power supply to motor internal contracting brake 4, embraces an operating case 3 and controls the break-make of motor internal contracting brake 4 band-type brake coils by opening, and embraces down sliding object thereby reach to open.
The utility model is by increasing uninterrupted power supply (UPS) 2, even if actv. has ensured the in the situation that of the unexpected power-off in building site, still can ensure that elevator can leave band-type brake normally, thereby can make elevator can walk to slowly on the ground, ensure the safety of elevator operation and workmen's safety.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
