Description
Technical field
The present invention relates to the emergency stop switch shift assembly in elevators field, especially a kind of elevator sudden-stop switch device moving up and down.
Background technology
Along with China's sustain economic stablize fast speed development, skyscraper increases sharply, and elevator is widely used, bring comfortable, enjoy efficiently.In China, there is elevator service more than 1,000,000 at present in multiple places such as office room, apartment, markets.Data according to Chinese elevator association show, in recent years, the elevator quantity that China puts on record on the regular payroll just with annual higher than 20% speed increment, become the country that global elevator recoverable amount is maximum.
Elevator belongs to special equipment, the fine or not direct relation of its quality the safety of user, so the safety requirements of elevator is very high, perfect maintenance could realize elevator reliability service, in elevator after-sales service maintenance business frequently, the personal safety of elevator maintain and protection personnel is also very important.
In the daily repair and maintenance or checkout procedure of elevator; elevator maintain and protection personnel must enter pit and carry out operation; emergency stop switch near elevator pit entrance (suddenly stopping) be serially connected in one in elevator control chain can not automatically reset hand switch; when in case of emergency; for preventing elevator startup optimization, need emergency stop switch to be closed cutting-off controlling circuit to ensure safety.
When entering pit, first stopping pressing (cutting-off controlling circuit) by anxious, carrying out after entering pit overhauling, repair and maintenance; or again by suddenly stopping recovery carries out every inspection, to the anxious quantity not requirement stopped, as long as it is just passable to meet operating needs; so fill one, also have and fill that two urgency stop.
When filling a urgency and stopping: be generally arranged on place slightly higher than landing sill near pit entrance, repair and maintenance personnel are opening layer behind the door, or half couchant body hand presses anxious stopping, or directly presses with pin, is made with certain difficulty like this, both inconvenient, too increase danger (as fallen lower pit), and after going down from cat ladder, if cat ladder is not near anxious stopping, stand in pit and want that the urgency recovering eminence stops also there is certain difficulty, when particularly pit is darker.
When filling two urgency and stopping: general upper urgency stop being contained in high apart from landing sill about 1.5 meters near, the next anxious stopping is contained in apart from the high well enclosure in about 0.5 meter, the end of hole, and generally, two urgency have cat ladder near stopping.When entering pit; first upper urgency is stopped pressing; then climb down pit to stop pressing by anxious for bottom; then climb up cat ladder upper urgency to be stopped recover; climb down that pit carries out overhauling, repair and maintenance again; or more anxious for bottom stopping is recovered, carries out every inspection, after inspection man completes, more also to first press before climbing out of pit by cat ladder the nextly suddenly to stop, press upper urgency stop, recovers bottom suddenly stop, climb out of pit after recover upper urgency again and stop.Climb up like this and climb down for several times, add work capacity, reduce work efficiency, in practical operation, have inconvenience.
Above-mentioned two situations, there are some repair and maintenance personnel in practice when fatigue or in order to follow the line of least resistance, contrary to regulations requires anxious the stopping that be failure to actuate, and directly climbs up the situation climbing down pit repair and maintenance, inspection, this adds the probability of occurrence of safety misadventure virtually, has buried potential safety hazard.
Summary of the invention

Fig. 2 is front view of the present invention (single-rail).
Detailed description of the invention
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of elevator sudden-stop switch device moving up and down, comprise emergency stop switch 3 and erecting frame, emergency stop switch connects external source by cable 9.Erecting frame is made up of one group of adapter plate 5 and guide rail 10, and the upper, middle and lower of guide rail is packed on upper mounting plate, middle adapter plate and lower installation board respectively.
Upper mounting plate and lower installation board are installed pulley 4 and lower sheave 16 respectively, and these two pulleys are connected by conductor rope 7, and the outside face of these two pulleys is all shaped with multiple groove 15.Upper mounting plate is installed two anti-ropes be positioned at above top sheave and has taken off groove stop, lower installation board has been installed two anti-ropes be positioned at below lower sheave and has taken off groove stop 17.
Emergency stop switch is arranged on a slide block, and when guide rail is one (as Fig. 2), there is groove the both sides of guide rail, and the left and right sides of slide block to be installed on guide groove and along the upper and lower guiding movement of guide rail; When guide rail is two (as Fig. 1), two guide rails are arranged side by side, and the left and right sides of slide block lays respectively in the guide groove of two guide rails, and therefore slide block can drive emergency stop switch to do upper and lower guiding movement along guide rail.
Upper mounting plate installs a slow stop 2 of elasticity, the slow stop of this elasticity to be positioned at above emergency stop switch and to play position-limiting action to emergency stop switch, the slide block clamp 12 that one can be blocked slide block is set below emergency stop switch, upper mounting plate installs a mobile button 1, and slide block clamp is connected by brake cable 11 with mobile button.
A clump weight 13 installed by conductor rope, and the position of this clump weight and the paired linea angulata of emergency stop switch are arranged.This clump weight is made up of cylindrical shell and the upper end cover and bottom end cover being arranged on its two ends, and the outside of upper end cover connects conductor rope, and inner side connects a spring, and the other end of this spring is connected with the conductor rope be installed on bottom end cover, and this spring can make conductor rope keep tensioning state.The conductor rope of clump weight side is sleeved in a counterweight conduit 8, this counterweight conduit is installed on a mounting board, clump weight is positioned at counterweight conduit, counterweight conduit madial wall above and below clump weight to be installed respectively in counterweight stop 14 under stop 6 and counterweight, in this counterweight, under stop and counterweight, stop can play the effect of spacing clump weight.
Using method of the present invention is: elevator is moved up and down switching device and to be fixed near pit entrance on well enclosure behind appropriate location:
1, layer door is opened:
When anxious stop (switch) be in bottom time, press mobile button, by brake cable, slide block clamp opened, suddenly stop freely to go upward to upper (clump weight declines) simultaneously, the slow stop of elasticity by suddenly stopping blocking, parked, press (disconnection) and suddenly stop, then descend pit.
(2), when suddenly stopping (switch) and being in upper, press (disconnection) and suddenly stop, then descend pit.
2, after lower pit, by the next pulley (with hand by rotating 4-5 circle on the groove of pulley), anxious stopping is pulled down (clump weight rises simultaneously), slide block under emergency stop switch is stuck on slide block clamp and (namely suddenly stops being fixed on lower position), at this moment can recover anxious to stop the work of testing or do not recover anxious to stop, carry out maintenance work.
3, after work completes, when will get on from pit, if (suddenly stop not in off-state, anxious stopping is pressed) according to regulation, mobile button is pressed after cat ladder climbs out of pit, by brake cable, slide block clamp is opened, suddenly stops freely to go upward to upper (counterweight decline simultaneously), emergency stop switch blocks by the slow stop of elasticity, parked.At this moment emergency stop switch (recovering anxious to stop) is rotated.------uses and terminates, closed layer door.
