Description
Technical field
The utility model relates to lift car field, relates in particular to the elevator car top that a kind of elevator car rack upper beam and sedan-chair top are designed to integral structure.
Background technology
Lift car is the space of elevator load personnel and goods, lift car is generally comprised of sedan-chair wall, sedan-chair top, floor and car frame, car frame is born the weight of car and appurtenances thereof, by suspension gears such as steel rope or steel bands, is drawn and is driven car to move up and down.Car frame generally consists of both sides vertical beam and upper beam.Wherein, upper beam is arranged on sedan-chair top, is the supporting member of car lifting.In prior art, upper beam and sedan-chair top are designed to respectively two independent parts, as shown in Figure 1.
Sedan-chair top is the framing member with certain mechanical strength, has the function of bearing personnel's maintenance, emergency evacuation.According to GB7588-2003 < < elevator, manufacture and safety standard > > 8.13.2 regulation is installed, " sedan-chair top should have and is at least the net area that people from station of 0.12m2 uses, and its minor face is at least 0.25m." 5.7.1.1 bar regulation, " counterweight is completely static while being compressed on energy disperser, and should there be enough spaces car top, and the size in this space is as the criterion can hold a cuboid that is not less than 0.5mX0.6mX0.8m, and placement can anyly flat down.”
Because counterweight needs, upper beam operated by rotary motion is above sedan-chair top, its horizontal projected area is within sedan-chair top area, this arranges and brings difficulty for the especially small-sized passenger elevator of elevator, on the one hand, the facilities such as door opener, apparatus for examination and repair, draft equipment will be arranged above in sedan-chair top, on the other hand, reserve the space that meets standard specifications.Therefore, prior art, when small design passenger elevator, tends to a car frame both sides vertical beam and lengthens, and the distance that makes upper beam leave sedan-chair top can meet the standard-required of " any placement that flats down of cuboid of 0.5mX0.6mX0.8m ".
The problem of bringing is thus that (1) car frame structure strengthens, and causes waste of material; (2) car integral body, because upper depth of beam increases, causes shared building area (elevator hoistways) to increase thereupon; (3) integrally-built the increasing of car causes and system unstability easily produces the negative consequences such as vibration, noise, distortion.
Utility model content
The purpose of this utility model is exactly in order to address the above problem, the elevator car top structure that a kind of elevator car rack upper beam and sedan-chair top are designed to integral structure has been proposed, this integrated elevator sedan-chair roof construction has been saved material and space, reduced resonance, noise phenomenon, the riding comfort of elevator is obviously improved.
To achieve these goals, the utility model adopts following technical scheme:
An integrated elevator sedan-chair roof construction, comprising: car top board and car frame; Described car top board is connected with car frame upper beam, and described car top board and car frame upper beam are arranged on same continuous level, jointly form elevator car top.

2, save material and space
Same size elevator is in the situation that car free height is constant, because upper beam installation site reduces (at least 0.5m), the column height of car frame both sides decreases, thus, can reduce at least 0.5m of architectural top spatial altitude direction, save car frame both sides stud materials at least 0.5mX2 root, middle top board length (1400～1600) X according to one of the upper beam width (m) of design.The 630Kg specification elevator of take is example, and every elevator is saved direct material and taken more than 1500 yuan, saves the wide X building of space building hoistway hoistway and is deep to few 0.5m.
3, improved riding experience
Because intensity needs, upper beam generally adopts 4mm (being not limited to) steel plate to be rushed, rolled over and be processed into load larrying member beam by machinery, and its natural frequency, modulus of elasticity, amount of deflection, distortion etc. are completely different from the wallboard that other forms sealing car.Therefore, the diverse member of two parts natural frequency has changed the natural frequency of the lift car that only has single wallboard formation, forms damping, causes that the original driving force of shock of elevator car is suppressed, lift car resonance, noise phenomenon reduce, and the riding comfort of elevator obviously improves.
4, reduced technology difficulty
After upper beam and the integrated design of sedan-chair top, for guaranteeing that upper beam and sedan-chair top become a continuous level above, more than generally upper beam will move down 0.5m, bring more than the column of car frame both sides shortens 0.5m accordingly.
Known in the industry, mechanical processing technique complexity and quality control and part length size have inseparable associated.General lift car overall height 2.6m～3.0m left and right, under prior art, as guaranteed between the sedan-chair head space of small dimension elevator (upper beam is raised), the length of its two heel post tends to surpass 4.0m, at this moment, technology difficulty increases (4.0m is the increase point of technology difficulty coefficient), and the corresponding raising that requires to personnel's operation, equipment precision, quality control, causes productive costs to strengthen.
Adopt after this technology, strut length at least reduces 0.5m, and its technology difficulty, quality control are relatively easy, have virtually improved manufacture efficiency.
5,, after structure reduces, complete machine is arranged compacter, is conducive to design production, packed and transported and building site each link is installed.
