Elastic component.
The present invention carrys out tensioner steel wire rope by using two rope sheaves, and two ropes can be adjusted according to the limiter of speed of different-diameter
The spacing of wheel, improves the application of swelling device.And the present invention by floor installation on pit ground, it is to avoid be arranged on
Complicated attachment structure on guide rail, installs more flexible, space-consuming is smaller.Existing two rope sheaves of consolidation are pulled down by elastic component
Tensioner simultaneously, compared to the mode of traditional counterweight tensioner, construction weight of the invention is gentlier easily installed, and cost is also more
It is low.
Preferably, in addition to it is fixed on the base and the spacing dividing plate below the rope sheave mounting seat, fixation
The pull bar of the spacing dividing plate is connected in the rope sheave mounting seat and passes through up and down, the elastic component is connected to described
Between spacing dividing plate and the pull bar.
Wherein, the elastic component is spring.
Preferably, the hypomere of the pull bar have be additionally provided with external screw thread, the pull bar with the external screw thread coordinate with to
Keep off the inner thread piece of the elastic component.By the cooperation position for the external thread piece for adjusting inner thread piece and pull bar, it is possible to achieve right
The regulation of the pretightning force of elastic component, it is very convenient.
Preferably, the guide rod extended up and down is fixedly installed on the base, the rope sheave mounting seat is up and down
It is connected in the guide rod.
Preferably, the rope sheave mounting seat is respectively arranged on the left side and the right side the bar hole extended transversely, two ropes
Wheel is connected on the bar hole correspondingly respectively.The center line of the bar hole of the left and right sides is located along the same line, and leads to
Cross and be fixedly connected after two rope sheaves are moved left and right on respective bar hole, it is convenient to make two rope sheaves relatively close or remote
From so as to adapt to the limiter of speed of a variety of different-diameters.
Compared to prior art, elevator expansion apparatus of the invention is simple in construction, and lighter in weight is easy for installation, takes empty
Between it is smaller, can adapt to the limiter of speed in different-diameter.
