The specific embodiment

Below in conjunction with accompanying drawing and embodiment the specific embodiment of the utility model is further described:

Referring to shown in Figure 1, the special-purpose dumb waiter device of present embodiment nuclear station comprises machine room parts 1, car and sedan-chair frame 2, counterweight assembly 3, layer door gear 4 and hoistway parts 5, and machine room parts 1 are positioned at the top of whole hoistway, also is the power place of whole elevator.Car and sedan-chair frame 2 are connected with the steel rope of counterweight assembly 3 through towing machine 6, lean on the friction force of steel rope in grooving to drive car 2 and move up and down with counterweight 3.Layer door gear 4 is windows of operating personal and car 2 interactions, also is the barrier that operating personal and elevator hoistways are isolated.Hoistway parts 5 mainly provide functions such as guiding, safety guard-safeguard.

Referring to shown in Figure 2, machine room parts 1 comprise towing machine 6, track adjusting wheel 7, put parts such as machine beam 8 and control housing 9.Towing machine 6 is cores of elevator operation, and the friction through steel rope and grooving provides traction, thus drive car 2 or counterweight 3 upper and lower operations.Towing machine 6 through support with put machine beam 8 and fix, track adjusting wheel 7 is fixed on the support, puts machine beam 8 and fixes through built-in fitting in the hoistway 43 and hoistway.Control housing 9 is electrical control hinges of whole elevator, is controlling the operation of all electrical equipments.

Referring to Fig. 3, shown in Figure 4, car and sedan-chair frame 2 comprise at the bottom of sedan-chair top 10, sedan-chair wall 11, the sedan-chair 12, parts such as upright beam 13, upper beam assembly 14 and inside door 15.Because the restriction of nuclear power hoistway, with 12 wrapping in respectively in the sedan-chair wall 11 at the bottom of sedan-chair top 10 and the sedan-chair, upright beam 13 is close to sedan-chair wall 11 outsides, and 12 threes at the bottom of sedan-chair top 10, sedan-chair wall 11 and the sedan-chair are linked together, thereby saves the space.

Described upper beam assembly 14 is fixed with upright beam 13 upper ends, and upper beam assembly 14 comprises car rope hitch plate 16, the foreign material ladder is led parts such as boots 17, magnetic induction switch 18, overload device 19, cage top overhauling case 20, arrival gong 21, buzzer phone 22 and safety pin device 23 for a short time.Described car rope hitch plate 16 is used for fixing car fag end device 25; And overload device 19 is installed through overload support 24 in the spring top at car fag end device 25; When car 2 overload, promptly the length of spring compressed of car fag end device 25 surpasses certain limit, and overload device 19 sends signal and gives buzzer phone 22; This moment, buzzer phone 22 sent sound, the overload of alert elevator.It is car 2 links along guide rail 39 direction operations that described foreign material ladder is led boots 17 for a short time, and requires to spray again according to nuclear power.Described magnetic induction switch 18 adopts the degree of protection of IP67, has satisfied the operating needs of nuclear power environment, and it mainly works when car 2 flat beds.After Elevator landing arrived at a station, arrival gong 21 sent sound, and alert car 2 arrives at a station.

Described safety pin device 23 is actually an electromechanical interlocking device, and according to up-to-date dumb waiter national standard (GB25194-2010), this dumb waiter needn't be equipped with safety tongs; But because sedan-chair top 10 needs the station people, therefore the measure that should have the personnel of preventing to fall increases by two cover safety pin devices 23 specially in upper beam assembly 14; When having personnel to install or keeping in repair, the latch on both sides 26 injected be fixed on the adapter plate on the guide rail 39, and trigger limit switch 27; Make car 2 be parked in this layer, treat end-of-job after, latch 26 is extracted; Limit switch 27 resets, and car 2 can normally move, to guarantee installation, maintenance personnel's safety.

For preventing that protective clothing and hoistway parts 5 hooks produce danger in the process of transporting, increase inside door 15 one on car 2 doorways, described inside door (15) is actually a manual door curtain of rail mounted;, door curtain is hung up during protective clothing in shipment with the door curtain hook, treat that protective clothing is all put into after; Door curtain is put down, again the sedan-chair case is put in the door curtain hook, because all there is track the both sides of door curtain; Thereby having guaranteed that car (2) door curtain in operational process does not produce rocks, and has increased safety in operation.

Described counterweight assembly 3 is the weight in order to balance car 2, the consumption of power of minimizing towing machine.Comprise that counterweight leads boots 28, parts such as counterweight framework 29, counterweight iron 30, dash plate 31, counterweight rope hitch plate 32.It is consistent that described counterweight is led the effect that boots 28 and car lead boots 17, is the link of counterweight assembly 3 along guide rail 39 direction operations.Described counterweight rope hitch plate 32 is used for fixing counterweight fag end device.All parts surfaces all require spraying according to nuclear power, to adapt to the particular surroundings of nuclear station.

Described layer door gear 4 comprises fireprotection layer door 33, doorframe 34, door pocket 35, door lock 36, installation accessories 37 and calls case 38 outward.Described fireprotection layer door 33 is manual form, will in another patent, describe.Described door lock 36 adopts the electromechanical interlock formula, has only when re-packing on the car 2 bumps against the croquet of mechanical door lock, and layer door 33 just can be opened; Have only the layer of working as door 33 to close, electric door lock contacting, car 2 could move.Doorframe 34 all adopts fire proofing with door pocket 35 and installation accessories 37, really accomplishes fire prevention, fire-retardant.Described outer calling case 38 adopts the degree of protection of IP55, and at the basic unit station service of lock ladder is set, in case the lock ladder, the calling of any stop is all inoperative.

Described hoistway parts 5 comprise parts such as guide rail 39, rail brackets 40, limit switch 41, Buffer Unit 42 and built-in fitting 43, and guide rail 39 mainly is that directional tagging is played in the operation of lift car 2 or counterweight 3 with rail brackets 40; Limit switch 41 is the upper and lower operational limit positions that are used to limit car 2, prevent to rush to summit or pier at the bottom of; Buffer Unit 42 is last pipe protections of elevator operation, is used to absorb the kinetic energy that car 2 or counterweight 3 are produced when surpassing upper and lower end position; Because the particularity of nuclear station environment for use, rail brackets 40 can only be fixing with built-in fitting 43 welding.

Be to produce the operation that friction drags car 2 and counterweight 3 by drive motor control traction sheave and steel rope in the present embodiment, under the prerequisite of not violating the utility model technical conceive, the operation of elevator also can take hydraulic driving mode to realize.
