Description

A kind of elevator balanced compensated guiding damping device

Technical field

This utility model relates to elevator technology field, a kind of elevator balanced compensated guiding damping device.

Background technology

Along with skyscraper gets more and more, elevator, as the means of transport of vertical direction, has become as the indispensable Architectural Equipment of skyscraper and public place.Traction elevator the most all includes the elements such as car, traction steel-cable, counterweight, trailing cable, and elevator is in running, and the length of the steel wire rope of cage side and counterweight-side is being continually changing, thus causes the change of traction sheave both sides steel wire rope weight.When car is positioned at minimum stop, the weight major part of steel wire rope acts on cage side；When car is positioned at top station, the weight major part of steel wire rope acts on counterweight-side.The runnability of elevator, when lifting height of lift is little, is affected little, but when being lifted beyond certain altitude, can have a strong impact on the stability that elevator runs, jeopardize the safety of passenger by this change.To this end, when the hoisting depth of elevator exceedes certain altitude, it is necessary to setting has the parts of constant weight and balances the weight change brought because of height change, here it is elevator balanced compensated chain.

The compensated chain guider of the most existing middle slower elevators, it is only capable of carrying out spacing with the direction of car line to compensated chain at counterweight, and backstop stopping means is not had in the direction of counter weight guide track line, so in counter weight guide track line direction, when elevator compensation chain running has bigger oscillating quantity, easily cause compensated chain to interfere with the buffer of counterweight-side and the base of buffer, cause fault to stop ladder, and existing elevator compensation chain in running with contact vibrations between guider and noise is bigger.

The elevator balanced compensated guiding damping device that this utility model provides also has a techniques below feature:

Further, described guide pipe two ends are further fixed on the guide rail splice for being connected with counter weight guide track, and described guide rail splice is connected by U-bolt and described guide pipe are fixing.

Further, the damping sebific duct on described guide pipe is between described position-limiting tube and described U-bolt.

Further, described position-limiting tube is provided with radial direction through hole away from one end of described guide pipe, is equiped with the split pin for fixing damping sebific duct in described through hole.

Further, described position-limiting tube is welded on described guide pipe.

This utility model has the advantages that guide pipe can carry out guide and limit to the compensated chain of elevator on the line direction of the car of elevator and counterweight, the compensated chain of elevator can be carried out spacing in counter weight guide track line direction by the position-limiting tube on guide pipe, the compensated chain oscillating quantity on the counter weight guide track line direction of elevator preventing elevator is excessive, thus prevents the compensated chain of elevator from causing fault to stop ladder in buffer or the buffer base interference of the swing of the counter weight guide track line direction of elevator with elevator；Damping sebific duct on guide pipe and position-limiting tube prevents the compensated chain of elevator from directly contacting generation vibrations and noise in motor process with guide pipe or position-limiting tube so that the operation of elevator compensation chain is more smooth and easy.

Detailed description of the invention

Below with reference to accompanying drawing and describe this utility model in detail in conjunction with the embodiments.It should be noted that in the case of not conflicting, the embodiment in this utility model and the feature in embodiment can be mutually combined.

nullIn one embodiment of of the present utility model elevator balanced compensated guiding damping device as shown in Figures 1 to 5，This elevator balanced compensated guiding damping device includes car 60、Counterweight 50、Counter weight guide track 20 and compensated chain 40，Car 60 is connected by steel wire rope with counterweight 50，Compensated chain 40 is for balancing the weight of elevator rope and trailing cable，The bottom of counter weight guide track 20 is fixed with compensated chain guide pipe 10 on counter weight guide track 20 line direction，The height of guide pipe 10 in the vertical direction is less than the top of the buffer 30 of elevator，Two position-limiting tubes 11 being perpendicular to guide pipe 10 it are additionally provided with on guide pipe 10，Two position-limiting tubes 11 are arranged along the centrosymmetry that guide pipe 10 is axial，Distance between two position-limiting tubes 11 is more than the base 31 of the buffer 30 of elevator width on counter weight guide track 20 line direction，The two ends of guide pipe 10 are also arranged with damping sebific duct 13，Two position-limiting tubes 11 are all arranged with damping sebific duct 13.Elevator balanced compensated guiding damping device in this embodiment, guide pipe can carry out guide and limit to the compensated chain of elevator on the line direction of the car of elevator and counterweight, the compensated chain of elevator can be carried out spacing in counter weight guide track line direction by the position-limiting tube on guide pipe, the compensated chain oscillating quantity on the counter weight guide track line direction of elevator preventing elevator is excessive, thus prevents the compensated chain of elevator from causing fault to stop ladder in buffer or the buffer base interference of the swing of the counter weight guide track line direction of elevator with elevator；Damping sebific duct on guide pipe and position-limiting tube prevents the compensated chain of elevator from directly contacting generation vibrations and noise in motor process with guide pipe or position-limiting tube so that the operation of elevator compensation chain is more smooth and easy.
