Abstract

The utility model discloses a rotatable crosshead sheave device, which comprises a top sheave device, a damping device and a connection part, wherein the top sheave device and the damping device are connected together through the connection part. The rotatable crosshead sheave device can achieve 360-degree rotation of a crosshead sheave so that a crosshead sheave is suitable for installation in various directions, unnecessary troubles to design staff of an elevator can be reduced, and installation of installation workers can be easier.

Description

A kind of rotatable crosshead sheave device

Technical field

The utility model relates to a kind of elevator crosshead sheave device, belongs to lift facility.

Background technology

Crosshead sheave on the existing elevator sedan-chair top all is a captive joint; Do not possess and to turn to function; Elevator design personnel arrange because the elevator reserved location of building has influence on elevator structure sometimes; And need to change original design, in the elevator installation process, also can bring some inconvenience simultaneously to installation personnel.

Summary of the invention

In order to solve the problems of the technologies described above, the purpose of the utility model is to provide a kind of rotatable crosshead sheave device, is convenient to the designer and designs elevator and installation personnel construction and installation.

The technical scheme that the utility model adopted is:

A kind of rotatable crosshead sheave device, said crosshead sheave device is made up of link, damping base and the rope sheave that has a protective case, and said rope sheave and the damping base that has protective case links together through link from top to bottom.

Improvement as technique scheme; The rope sheave of said band protective case links together through link and damping base; Because link is an oval axle; Rope sheave just can carry out the rotation of any direction, thereby is fit to the elevator hoistways of arbitrary shape, makes installation personnel simpler and easy in the process of installing simultaneously.

The beneficial effect of the utility model is: this rotatable crosshead sheave device is owing to adopt the axle ways of connecting that crosshead sheave is connected with elevator car frame; Realize 360 degree rotations of crosshead sheave; Make things convenient for the elevator design personnel to design elevator and elevator installation personnel installation elevator; The shock absorption device that adds simultaneously more can reduce the vibrations degree in the elevator cage operation process, the comfort when the increase people take elevator.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.

Fig. 1 is the structural representation of the utility model.

The specific embodiment

With reference to Fig. 1; The rotatable crosshead sheave device of the utility model; Above-mentioned rope sheave 2, rubber ring 9, entablatrance 8, shock absorption device 7 and the base 6 that has protective case couples together with oval axle 4 and coupling nut 5 from top to bottom; Also coupling nut 5 is locked simultaneously, prevent that coupling nut 5 breaks away from pin 14.

Entablatrance 8, shock absorption device 7 and base 6 bolt through 2 symmetries is in the same place by being linked in sequence from top to bottom, forms the base mechanism with shock-absorbing function, make elevator in operation more steadily and safety.

Guard shield 12 is connected on above the top wheel carrier 10 through bolt; 11 of crosshead sheave assemblies are installed in wheel carrier the inside, top through last item plate 13; Thereby constitute a rope sheave mechanism, can prevent effectively that each position of health from getting into rope sheave, prevent that simultaneously foreign matter from dropping to the rope sheave the inside with protecting sheathing; Cause the card wheel and take off rope, make elevator safer.

This rotatable crosshead sheave device can change the direction of rope sheave, thereby reduces unnecessary misgivings when making elevator design, also makes the work of installation personnel simpler and easy simultaneously.

The above is merely the preferential embodiment of the utility model, as long as realize that with basic identical means the technical scheme of the utility model purpose all belongs within the protection domain of the utility model.
