Description
Technical field
The utility model relates to a kind of lift car, is specifically related to a kind of lift car of extensible space.
Background technology
The GB50096-2011 " Code for design of dwelling houses " that on August 1st, 2012 enforces wherein 6.4.2 bar clearly specifies: " Floor 12 and house more than Floor 12, Mei Dong building arranges elevator and is at least no less than two, and wherein one can be held the elevator of stretcher." new regulation considers from hommization, can facilitate in emergency circumstances the personnel's of speedily carrying out rescue work rescue of registering one's residence.
Under normal circumstances, the elevator that people are daily used, its car shape is changeless, area and volume are also fixed.Exactly because car shape, area, volume are changeless, therefore at some in particular cases, such as transporting the object of some more microscler shapes, during such as first aid stretcher or emergency ward bed, just can not meet the demands.
According to the regulation in China's " elevator manufacture and installation safety standard " GB7588-2003, the passenger elevator of payload ratings 1000KG, conventional internal dimensions is that 1600mm(is wide) × 1400mm(is dark), it is wide at 2200mm(that its corresponding elevator is installed tunnel dimension) × 2200mm(is dark).But the emergency ward bed or the first aid stretcher length that possess medical first aid function are 1900mm left and right, this size is basic just cannot translation transport patient.And according in existing elevator standard GB/T 7025.1-2008 " pattern of elevator principal parameter and car, hoistway, machine room and size section 1: I, II, III, IV class elevator ", Fig. 9 is usually used in other designs of I class II class IV class elevator, wide for being of a size of 600mm() × 2000mm(is long) stretcher, the car design size of load-carrying 1000KG elevator is that 1100mm(is wide) × 2100mm (deeply), its corresponding tunnel dimension is that 2000mm(is wide) × 2600mm(is dark).Before new " Code for design of dwelling houses " GB50096-2011 enforces, building side is in design building, under normal circumstances, the elevator that payload ratings is 1000KG, is all wide according to conventional 2200mm() × 2200mm(is dark) tunnel dimension design.And after new rule enforcement, for meeting the demands and minimizing cost, one is that 2200mm(is wide) × 2200mm(is dark), it is wide that another is designed to 2000mm() × 2600mm(is dark), so just cause the size of two hoistways inconsistent, can cause the waste of the inconsistent or building cost of building interior space lattice.In addition, China is existing did not all consider stretcher delivery functions with passenger elevator before new rule are implemented, if considered from hommization, if will carry out function modifications to it, because existing hoistway area has been determined, be subject to the restriction of tunnel dimension, difficulty is too large.Therefore, solve and not change conventional hoistway area, use the little cost of nominal payload lower elevator conveying to lie low and be at least the patient on the stretcher of 1.9 meters in length, just become a urgent need to solve the problem.
Utility model content
The defect existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of lift car of extensible space, this car is under the constant prerequisite of original standard lift tunnel dimension, reach can the come in and go out object of lift car of stretcher, without stretcher lift of customized design, hoistway is installed, not only convenient construction, and can save building cost.
For achieving the above object, the technical solution of the utility model is: the lift car in extensible space, comprise the car cab being surrounded by car walls, described car walls comprises fixing sedan-chair wall and car extension mechanism, between described car extension mechanism and fixing sedan-chair wall, be flexibly connected, described car extension mechanism can launch to form to car outside and hold the space of carrying on a shoulder pole object.
Adopt technique scheme just can increase hardly under the prerequisite of car weight, reach the object in extensible space, elevator is installed to larger space between the sidewall of hoistway and the relative gate of car cab and rear wall to be used, described car cab under normal circumstances, while thering is no wider space, the center of gravity of car and the outside dimension of car cab are almost constant, in the time transporting stretcher or large part object, the space of the held stretcher that expansion car extension mechanism extends to form, in the time that transport first-aid patients stretcher enters car cab, stretcher one end can level be stretched in wider space, the utility model is applicable to standard lift hoistway is installed, without increasing the size that hoistway is installed, do not need to change the mounting means of any parts of elevator hoistways yet, but can meet the requirement of stretcher discrepancy car, wider space can be realized folder function, so need not be the installation hoistway of a stretcher lift of house customized design, not only convenient construction, and can save building cost.
Further, described car cab also comprises fixing sedan-chair top, extending top board, at the bottom of fixing sedan-chair, extending base plate and gate, car walls top is fixing sedan-chair top, car walls bottom is at the bottom of fixing sedan-chair, fixing sedan-chair wall comprises the antetheca towards gate, the rear wall relative with antetheca, and front, sidewall between rear wall, described sidewall, the intersection of rear wall or sidewall and rear wall at least arranges the car extension mechanism in an extensible space, this car extension mechanism comprises fixing or telescopic extending top board, extending base plate and can launching or superimposed extending sedan-chair wall, this extending sedan-chair wall is flexibly connected with adjacent fixing sedan-chair wall, extending top board is fixedly connected with or is flexibly connected with car cab with extending base plate, extending sedan-chair wall launches rear and extending top board, extending base plate forms the space that can hold stretcher.
Further, described extending sedan-chair wall, for outwards rotary, comprises at least two extension sedan-chair walls, and extension sedan-chair wall is to be rotationally connected or the mode of sliding block joint and corresponding sidewall or rear wall connects and motion in contrast.
Further, described extending sedan-chair wall is collapsible or plug-type, comprise at least two extension sedan-chair walls and the shrouding between extension sedan-chair wall, extension sedan-chair wall is with corresponding sidewall or rear wall is hinged and motion in contrast, promotes shrouding and move the space that final formation can be held stretcher after extension sedan-chair wall launches.
Further, extending top board is positioned at sidewall, rear wall or the intersection near sidewall and rear wall, concordant with fixing sedan-chair top or in the relative lower position, sedan-chair top of fixing, this extending top board is fixedly connected with bolt or extends out with the top relative motion of fixing sedan-chair and outside car in the mode of rotating hinged or sliding block joint.
Further, extending base plate is positioned at sidewall, rear wall or the intersection near sidewall and rear wall, concordant with at the bottom of fixing sedan-chair or have the poor position of certain altitude in relative at the bottom of fixing sedan-chair, this extending base plate is fixedly connected with bolt or to rotate at the bottom of the mode of hinged or sliding block joint and fixing sedan-chair relative motion and to extend out towards car outside.
Further, the height and position of described extending base plate with at the bottom of fixing sedan-chair, flush or coordinate with the height and position of extending sedan-chair wall, when stretcher head end advances car extension mechanism to launch the spatial accommodation of formation, extending base plate strength reaches the requirement of strength that supports stretcher transport patient.
Further, the type of drive of described extending sedan-chair wall is that motor drives, and motor is driven extending sedan-chair wall to swing or slided by transmission device.
Further, also comprise contact switch and limiting stopper.
