The present invention carrys out tensioner steel rope by adopting two rope sheaves, can regulate the spacing of two rope sheaves, improve the field of application of swelling device according to the velocity limiter of different-diameter.And the present invention by floor installation on pit ground, avoid the complicated connection structure be arranged on guide rail, install more flexible, take up room less.Pull down existing two rope sheaves of consolidation tensioner simultaneously by elastic component, compared to the mode of traditional counterweight tensioner, structural weight of the present invention is gentlier installed easier, and cost is also lower.
Preferably, also comprise and be fixed on described base and be positioned at spacing dividing plate below described rope sheave mount pad, be fixedly connected on described rope sheave mount pad and up and down through the pull bar of described spacing dividing plate, described elastic component is connected between described spacing dividing plate and described pull bar.
Wherein, described elastic component is spring.
Preferably, the hypomere of described pull bar has outside thread, described pull bar is also provided with the inner thread piece coordinating to keep out described elastic component with described outside thread.By regulating the cooperation position of the external thread piece of inner thread piece and pull bar, the adjustment of the predetermincd tension to elastic component can be realized, very convenient.
Preferably, described base is fixedly installed the pilot bar of downward-extension, described rope sheave mount pad is connected in described pilot bar up and down.
Preferably, the left and right sides of described rope sheave mount pad is respectively equipped with the bar hole extended transversely, and two described rope sheaves are connected on described bar hole respectively correspondingly.The line of centers of the bar hole of the left and right sides is located along the same line, by two rope sheaves are fixedly connected with after sway on respective bar hole, can make easily two rope sheaves relatively near or away from, thus adapt to the velocity limiter of multiple different-diameter.
Compared to prior art, elevator expansion apparatus structure of the present invention is simple, and lighter in weight is easy for installation, takes up room less, can be adapted to the velocity limiter of different-diameter.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Embodiment one
Refer to Fig. 1 and Fig. 2, a kind of elevator expansion apparatus, comprise be fixed on pit ground 10 base 8, be up and down arranged on rope sheave mount pad 2 on base 8, between left and right every arrange and adjustable interval be arranged on two rope sheaves 1 on rope sheave mount pad 2, make rope sheave mount pad 2 have the spring 5 of the trend of moving downward.
In the present embodiment, this elevator expansion apparatus also comprises and is fixed on base 8 and is positioned at spacing dividing plate 81 below rope sheave mount pad 2, is fixedly connected on rope sheave mount pad 2 and up and down through the pull bar 3 of spacing dividing plate 81, the two ends up and down of spring 5 are provided with axle sleeve 7, the axle sleeve 7 of spring 5 and upper and lower side thereof is all enclosed within pull bar 3, fixed by the inner thread piece on pull bar 3, spring 5 is connected between spacing dividing plate 81 and pull bar 3.
By the spring 5 compressed in advance, pull bar 3 is pulled down, thus make rope sheave mount pad 2 have the trend of moving downward, with tensioner steel rope 9.And the spacing of two rope sheaves 1 can adapt to the velocity limiter of the different-diameter be arranged on above hoistway after regulating.In order to make left and right stress balance, the quantity of pull bar 3 is two, and two pull bars 3 are symmetrical set.
In another embodiment, also spacing dividing plate 81 can be arranged on the top of rope sheave mount pad 2, pull bar 3 extends up through spacing dividing plate 81, by being connected to spring 5 between spacing dividing plate 81 and rope sheave mount pad 2 by rope sheave mount pad 2 to pressing down, equally also can realize making rope sheave mount pad 2 have the trend of moving downward with the effect of tensioner steel rope 9.
