Description

Curved escalator

The utility model relates to a kind of screw elevator.

Domestic escalator is used seldom, only in the bigger building of minority passenger flow operational throughput, open straight line escalator has been installed.External escalator has been developed technology such as step pectination engaging structure from the closed box-shaped automatic elevator of the beginning of this century, develops into the open straight line escalator of present more use, and generally by the two strands traction, the step that drives staircase moves up or down for it.To the fifties as coordinating mutually with the social change that beautifies space and pursue high life, experienced the mark that crooked rectangular stage and then circular arc escalator have become luxurious lounge and mansion.The clear 61-178389 of Japanese Patent discloses a kind of curve escalator, this escalator also adopts double-stranded traction, therefore planting staircase is that concentric running rise, must make the radius of curvature of the nearly center of step one end little, other end radius of curvature is big, and with two chain gears, its sprocket wheel varies in size, chain pitch is also different, and each step that so just can make escalator steadily and concentric running rise or decline to reach helix.But to draw the curve escalator of 360 ° of concentric running with two strands, it is design or to make, install all be unusual difficulty, be difficult to realize the anglec of rotation only being arranged for this reason so far in the world less than 180 ° curve escalator, and 360 ° of curve escalators without spin.

The purpose of this utility model is: provide a kind of new design that can rotate 360 ° curve escalator, be by adopting two cover actuating devices up and down, drive the transmission of wall scroll universal chain, constitute that a single guided way bounded system realizes, thereby the path of motion of the ascent stage of escalator can be carried out 360 ° of revolution layouts; And can be with its escalator that gets up to do the multilayer flooring continuously, and descent stage can be arranged in the locus of centre of gration.Its manufacturing, installation are easy to realize simply that the function And that not only reaches curve escalator itself enlarges elevator user's the visual field, thereby it is comfortable to feel relief, simultaneously can also with the present age different styles Architectural Equipment be complementary, give beautiful enjoyment.

Content of the present utility model: whole curve escalator is to drive with strand, form by actuating device, universal chain, step and frame, frame 2 is made up of following transition zone frame, helix section frame, last transition zone frame, top circular arc section frame, last curved section frame, perpendicular segment frame, arc lower section frame, the bottom circular arc section frame of band cross guide rail groove, and forms the rising and the decline return movement track of curve escalator.

Its motion process is at every rising one deck flooring height, and three phases be arranged:

1. step forms section: step is with universal chain, under the transmission of actuating device, begin to rise on the ground by subsurface, the rise difference is progressively from the one-level step height that is raised to above freezing, it rotates 20 ° around the center, radius of turn can come selected by actual space size.

2. step spiral rising section: this section rise difference remains unchanged, lead angle is also constant, and it rotates 320 ° around the center, and radius of turn is with last identical.

3. step disappearance section: in this section, the rise difference is reduced to till zero gradually by one-level step height, and promptly fully equal with the last layer flooring when step, it rotates 20 ° around the center, and radius of turn is with last identical constant.

Above three phases step is around 360 ° of same center rotations, and first floor has risen.It can successively repeat above three phases, continue to rise to required floor height, and when backhaul, always no matter risen how many floors for three phases promptly:

4. step is at last circular arc section: this section is the step section that disappears that continues, promptly when step with after the last layer flooring is equal, just under this floor face, move immediately, the beginning step still descends to rotate with last identical radius around the center, when rotation dropped to the step tread and gradually becomes retroverted state by horizontality, step changed centre of gration and radius of turn.Rotated 180 ° at this section step, descended less than the height of one-level step.

5. step descent stage: this moment, step was with the changed course of universal chain through a changed course chain wheel set, make step by travelling forward, change into and move downward, after dropping to below the lowermost layer flooring always, universal chain belt step and is travelled forward from moving downward to along arc guide rail section frame again, and the step tread is a retroverted state.

6. step is at bottom circular arc section: the step tread becomes horizontality by hypsokinesis, and when section finished, step just rose to flooring under the bottom flooring, repeats each section that step rises again.This section has been rotated 180 °, radius of turn with at last circular arc section, the center of gyration in backhaul when decline is identical, to rising to less than the one-level rise, when progressively equal with flooring again, centre of gration is same center when rising again, with same radius of turn, until getting back to the starting point that begins to rise.

Here it is, and step rises, and the motion process that backhaul descends so universal chain belt each section that step rises, descends with closed circulation, constitutes whole path of motion.Need the floor of rising continuously higher, just more greatly, this can select the sealing ring of universal chain according to actual needs.

The concrete structure of curve escalator is: adopt the strand transmission, the universal chain structure of messenger chain, this structure allows a spot of reversing, and compares with adopting the double chain drive mode at present both at home and abroad, it is more suitable for being used for various curvature, different bending directions.If rising first floor, at ground floor subsurface level attitude one cover actuating device is installed, and the one nested structure actuating device identical with ground floor fully also is installed at the subsurface level attitude of next level, the mouth of this two covers actuating device, have a drive sprocket with by movable sprocket, on these two sprocket wheels, adorn an osed top driving chain, the outside of driving chain, every a pitch thumb wheel is housed, when driving chain is done the close cycle motion, it just with the block on the thumb wheel promotion universal chain, makes the universal chain motion.How many floors no matter the curve escalator rises, an actuating device that structure is identical is installed on the lower layer of water mean place of every floor face simultaneously, promote same the block on the universal chain simultaneously by the thumb wheel on each driving chain, make universal chain make enclosed circulating motion.Be that a block is installed on each pitch on the universal chain, the pitch of block is identical with driving chain thumb wheel pitch.So every next level is to have two driving chains on the actuating device to promote the universal chain motion.

The width of the one-level of on universal chain, being separated by step, the one-level step is installed, the tread of step is to be fan shape, two supports that vary in size are adorned at two ends below this, and adorn two rollers on every support, these two rollers, one in front and one in back not on same level attitude, but the line of centres of two rollers and tread horizon have an angle, and this angle is the lead angle of staircase, so support is leg-of-mutton.Under the step tread, interposition is equipped with one and connects frame, meeting frame end portion, with screw rod step and universal chain is linked together.Step is just made circulating motion with universal chain.

Universal chain is equipped with four rollers, these four rollers in center cross cross direction and embeds in the cross guide rail groove on the closed frame and move.This cross guide rail groove is to have on each section frame, thus this groove the same with frame also be enclosed.So strand transmission, 360 ° curve escalator of rotation come to this and form.
