A kind of elevator control gear
Technical field
The present invention relates to a kind of elevator control gear.
Background technology
At present traditional organic machine room-free elevator system is because elevator control device all is placed in the machine room, so have enough service clearances.But, in the Machineroom-less elevator system that grows up recent years,, becoming extremely difficult for the maintenance of elevator and the maintenance of control setup owing to there has not been machine room, the operation during particularly for emergency relief is more numerous and diverse.At this situation, also there are some producers to do some effort, as described in Chinese invention patent specification sheets CN 1048691C, control setup is installed in the opening of elevator hoistways wall, but this structural arrangement mode has bigger requirement for the layer reveal civil engineering of the corresponding floor of installation and control device, and about can't symmetry, influence layer door is attractive in appearance.And for example Chinese invention patent ublic specification of application CN1443133A and CN1343179A are described, control setup is installed in the hoistway, the maintainer carries out the maintenance of control setup by car roof, and its shortcoming is that the operator must enter hoistway, obviously has certain danger in operating process.And for example Chinese invention patent specification sheets CN1128754C is described, though it can be pulled out to control panel layer door place and overhaul and maintain, but owing to will carry out 90 degree space rotations, mechanism's complexity, performance difficulty, and the most important thing is control panel is pulled out to the car that the layer door place layer doorway of elevator (passenger directly come in and go out) can't the free lifting elevator when overhauling and maintaining (if will carry out the lifting car, must short circuit relevant door switch just can, have tangible danger).
At the disclosed removable may command dish that is used for elevator of U.S. patent of invention specification sheets US6230845B1, if carry out the maintenance of elevator control gear or on elevator control gear, carry out the inspection travel operation or the emergency operating operation of elevator, must meet certain condition: otherwise lift car is not installed floor at elevator control gear, need the elevator safety switches such as layer door interlock switch of short circuit elevator, must bring very big inconvenience and significantly dangerous like this.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of elevator control gear, and it can effectively solve the maintenance issue of machine-roomless lift and the maintenance problem of control setup, and civil engineering is easy, attractive in appearance, easy to operate, the safety of installation.
For solving the problems of the technologies described above, the technical scheme that elevator control gear of the present invention adopts is: this elevator control gear is placed in elevator hoistways wall surface or part in well enclosure or all in well enclosure when elevator normally moves, and all or part of of described elevator control gear can the direction along level in the elevator hoistways sidewall shift out the side of hoistway to stop passenger gangway straight when maintenance; In moving process and after the moving process end, other parts of described elevator control gear and elevator (as lift car, layer door etc.) are not all interfered.
Adopt after the said structure, service personnel can overhaul and control the emergency operating of elevator easily in the layer door position of elevator, operates also as safe as a house.In addition, also do not need to carry out special design in civil engineering, civil engineering is very easy to realize.This mounting structure can not change original project organization yet, and very attractive in appearance.
Description of drawings
The present invention is further detailed explanation below in conjunction with accompanying drawing and the specific embodiment.
Accompanying drawing is the embodiment scheme drawing of elevator control gear of the present invention in elevator hoistways and layer door position.
The specific embodiment
Accompanying drawing is to comprise elevator control gear of the present invention at interior elevator hoistways birds-eye view.Shown in the figure 1 is the elevator hoistways wall, the 2nd, and elevator hoistways, the 3rd, cage guide, the 4th, lift car, the 5th, elevator cab door, the 6th, elevator door, the 7th, elevator control gear and guide piece thereof, the 8th, elevator door mouth (passenger gangway).Wherein, elevator control gear and guide piece 7 thereof can be arranged in the left side of elevator door 6, also can be arranged in the right side of elevator door 6, even can be arranged in the left and right sides simultaneously.
As shown in the figure, elevator control device is designed to slim, and be installed in the elevator hoistways wall surface or the part in well enclosure or all in well enclosure, one kissing gate that can open by specific keys is arranged at layer door place, when elevator moved, elevator control gear was in hoistway, and this kissing gate is closed.When needs carry out the elevator control gear maintenance or carry out elevator emergency operation, open this kissing gate, the safety switch that has an interlock this moment disconnects the safety return circuit of elevator, guarantees that the elevator of this moment can not move.Then, guide piece by elevator control gear, elevator control gear is moved to the elevator door position from hoistway, the elevator control gear that is moved out of comprises inspection travel control setup, vital circuit cut-out equal controller, band-type brake control setup, elevator debugging interface arrangement, can observe the observation window of hoistway specific features etc.Obviously, in shifting out the whole process of hoistway, other parts of elevator control gear and elevator (as lift car, layer door etc.) are not all interfered.After this control setup moved into place, the safety switch closure of above-mentioned interlock allowed elevator to enter the inspection travel state.Thereby service personnel can overhaul and elevator emergency operation easily and safely, and the safety switch that when operation must be closed need not short circuit elevator normal operation the time (as layer door interlock switch etc.), the assurance personnel can not be hurt by mistake.By shifting out the band-type brake control setup of part, service personnel can be quite convenient and be carried out the rescue of machine-roomless lift safely, (this observation window can be direct perforate towards hoistway on the elevator control gear by the observation window that can observe the hoistway specific features on the extensible elevator control gear, also can be light, the electricity facilities for observation that is contained in the elevator control gear), service personnel can accurately be located the car position of elevator.
As shown in the figure,, owing to only need the slype of a band kissing gate, make this can decorate and make symmetrical structure in door place layer by layer, do not influence the attractive in appearance of this layer hall fully, also not for the specific (special) requirements of civil engineering at the layer door place that elevator control gear is installed.As seen the present invention has solved machine-roomless lift maintenance and rescue difficult problem fully, and the layer door of using elevator be as maintenance platform, makes the maintenance and the rescue safety, reliable of elevator.And, do not influence the attractive in appearance of this layer hall that elevator control gear is installed, do not influence the civil engineering of elevator yet.
