Description

A kind of strong drive formula host of elevator with two-fold cylinder

Technical field

The utility model relates to elevators fields, and in particular to a kind of strong drive formula host.

Background technique

Cage type elevator is widely used by people, and especially in skyscraper, elevator plays transport passenger and cargo Effect.Existing cage type elevator includes hoistway, the carriage in hoistway, the guide rail for being vertically provided at hoistway side and drives Carriage is along the host of lifting rail, and at work, host drives carriage to go up and down along track.Host includes driving formula and traction-type by force, Have the characteristics that structure is simple due to driving formula host by force, is used on the lesser home lift of hoistway.Existing strong drive formula host Reel including cabinet, the motor being mounted on cabinet and winding wire ropes, reduction assemblies are linked by universal driving shaft and reel, Mandrel surface is equipped with two embedding rope grooves disposed in parallel each other, and motor drives reel to rotate by reduction assemblies, so that reel is logical Folding and unfolding wirerope is crossed to pull carriage lifting.The strong drive formula host of this structure has the following deficiencies: reel and reduction assemblies point It sets on the both ends of universal driving shaft, when wirerope pulls reel, reel can apply oblique work to reduction assemblies by universal driving shaft Firmly, since reel needs interferingly two wirerope of folding and unfolding complementary simultaneously so that reel need by extend axially outward come Increase its axial dimension, at a distance from this adds increased reel outer ends between reduction assemblies, with winding of the wirerope on reel Position axis is moved out, and can also be increased with the oblique force fit arm of force, and the oblique active force that reduction assemblies are subject to is also bigger, in turn The structural strength for influencing reduction assemblies even results in cabinet and generates deformation, influences lift running safety.

Utility model content

In order to solve the deficiencies in the prior art, the utility model provides a kind of elevator with two-fold cylinder strong drive formula host, By the way that symmetrical reel is arranged on universal driving shaft, oblique active force was both offset each other using the reel of two sides, also passes through shortening Torque arm length reduces unilateral oblique active force, promotes the strong anti-deformation nature for driving formula host.

The utility model is accomplished by the following way: a kind of elevator with two-fold cylinder strong drive formula host, including cabinet, peace The reel of motor and winding wire ropes on cabinet, motor drive reel to rotate by reduction assemblies, so that reel is logical Folding and unfolding wirerope is crossed to pull carriage lifting, the strong drive formula host includes two symmetrically arranged reels, and the cabinet is equipped with With the universal driving shaft of reduction assemblies linkage, the universal driving shaft middle section is rotationally plugged on cabinet, both ends respectively with corresponding volume Cylinder is axial affixed, so that the reel synchronizes folding and unfolding wirerope.Original structure in universal driving shaft unilateral side setting reel is improved to In the structure of universal driving shaft two sides setting reel, symmetrically arranged reel can distinguish the corresponding wirerope of folding and unfolding, so that two reels The oblique active force of reversed dip each other can be generated to universal driving shaft, universal driving shaft is dropped by offsetting two groups of reversed oblique active forces The external force load of low reduction assemblies, and then play the role of protecting reduction assemblies and cabinet, further, since two wirerope difference The reel folding and unfolding winding split by two, shortens the axial length of single reel, and then effectively reduces unilateral oblique active force Dynamics, prevent the joining place of universal driving shaft and reduction assemblies because oblique active force is excessive occur bend deformation the case where, effectively Extend the strong service life for driving formula host.
