The specific embodiment
In order to understand the technical solution of the utility model better, also be described in detail in conjunction with the accompanying drawings below by specific embodiment:
See also Fig. 1 to Fig. 4; no pit attached wall elevator of the present utility model; this elevator and general elevator are basic identical, are made of traction system, guidance system, door system, car, counterbalancing system, electric drive system, autonomous cruise speed system and safety system equally.No pit attached wall elevator of the present utility model, comprise that attached wall hoistway 1, a cabinet 10, contain the towing machine of traction sheave 2, two track adjusting wheels 3,3 ', one car 4, a counterweight (not shown), one group of steel rope 5, a pair of car buffer 6, a counterweight energy disperser 7, lead boots 8, a weighting apparatus (not shown), a pair of safety tongs 9, one two-way velocity limiter (not shown) and a toeguard (not shown) under a pair of, wherein:
Attached wall hoistway 1 be fixed on one imbed underground and end face than the indoor terrace of building 11 at the bottom of and with the cooresponding solid foundation 12 of grade on; Elevator hoistways 1 adheres on the exterior wall that is installed in building 11, and elevator hoistways 1 is fabricated lightweight steel construction, and hoistway 1 is taked integrated installation with the cabinet 10 on its top, and sectional dimension is identical.Steel structure outside coats one deck high-strength cement plate.Be provided with machinery and electric parts such as car guide rail and counterweight guide rail in the hoistway 1.Have the series of layers door on the body of wall one side.
Towing machine has sure brake and adopts the type of drive of synchronous planet; The contact of sure brake circuit and bidirectional speed limiter links.
Two of steel rope 5 is from introducing two track adjusting wheels 3,3 ' top after traction sheave 2 comes out respectively, around to track adjusting wheel 3,3 ' below respectively with car 4 and counterweight fixed connection; The wrap angle sigma of steel rope 5 on traction sheave 2 is 200 °～250 °.During elevator work, under the driving of towing machine, car 4 moves up and down along the guide rail of attached wall hoistway 1 separately with counterweight.Steel rope 5 is 1:1 with the velocity ratio of car 4.
A pair of car buffer 6 is installed in corresponding car 4 both sides straight beams, 40 belows respectively and near on solid foundation 12 end faces of attached wall hoistway 1 wallboard, the respectively corresponding car buffer 6 in the lower end of car both sides straight beam 40 is installed buffer striking plate 60.
Weighting apparatus is located under the termination of steel rope 5 at car 4 tops.
A groove cave (not shown) that can hold toeguard is offered in corresponding toeguard below on the end face of solid foundation 12.The toeguard height of car 4 can correspondingly reduce according to elevator speed, and its principle is to guarantee the omnidistance required perception reaction time of toeguard contact.
Lead the top that boots 8 are located at the bottom of car both sides straight beam 40 and are positioned at safety tongs 9 under a pair of.
The following buffer striking plate 60 of leading boots 8, safety tongs 9 and car of car both sides is installed in respectively on the circuit board 42, and this circuit board 42 is linked together with the chassis 41 and straight beam 40 bolt ups of car 4.
Attached wall hoistway 1 near between the wallboard 14 of bottom and the derrick for removably connecting.Car buffer 6 and counterweight buffer 7 all are very little cylindrical, massive rubber and plastic bodies, need not maintenance, just in case need to safeguard, can open the wallboard 14 of attached wall hoistway 1 near the bottom, stretch out one's hand and can operate from the outside.After the cement wallboard 14 of attached wall hoistway bottom shed, the energy disperser 6,7 of hoistway bottom surface, car guide rail base 15, counterweight guiderail base 16, the safety tongs 9 at 4 ends of car, lead the buffer striking plate 60 of boots 8, car 4 and the parts such as buffer striking plate of counterweight down and come into plain view, very safe keeping in repair can be outside well, be easy to fully, the repertoire of elevator pit can be replaced thus.
The indoor terrace of building 11 bottoms is different with the height of grade, for modal two stair cases that run, grade will be lower than 50 centimetres of indoor terraces at least three, this depth difference as the diff-H between attached wall elevator solid foundation 12 planes and the ground floor terrace face, become the installing space of car base thickness and energy disperser, for attached wall hoistway 1 is exactly not have pit, and Here it is, and the attached wall elevator does not have pit design-calculated reason.
In addition, the synchronous planetary transmission that this elevator main adopts is a power dividing mechanism, a plurality of gears can not be shaved clearly simultaneously, the strength margin of its spline, axle and dish is all more than 2.5, can think that the transmission link between 2 is a failure-free from the brake disc to the traction sheave.The left and right sides brake disc of towing machine 2 is two sure brakes with absolute coil, independent friction member, and in addition, the kinergety of low speed underloading car is littler tens times than high-speed overload car.Therefore, the drg that is used for the drg of synchronous planetary transmission towing machine of attached wall elevator and gearless machine is the same, also can regard the up-running over-speed protection element as, need not add Machine guarding in addition.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
