Description

A kind of rope can common rail hoisting mechanism

Technical field

The utility model relates to engineering machinery field more particularly to a kind of rope can common rail hoisting mechanism.

Background technique

Hoisting mechanism is also referred to as winch, electric block, is by with reel winding wire ropes or chain lifting or traction Lifting equipment, the hoist engine generallyd use at present be by motor, shaft joint, brake, retarder, reel, guiding slide The composition such as wheel, lifting pulley group, fishhook, when work, motor rotation sends power to elevator by shaft coupling, retarder Wheel, to realize the lifting of weight, problem is also apparent elevator wheel belt running rope rope, is often occurred in actual use disorderly Phenomena such as rope, required rope length is longer, to realize that double-rope or right angle rope stretching and other effects also need additionally to increase equipment, cost into One step raises.

It is disclosed on December 22nd, 2010, " lever gear door is electronic with horizontal rope stretching for Publication No. CN2016793378U entitled Cucurbit " discloses a kind of horizontal double-rope electric block of lever gear door, and the patent or major part continue to use the prior art, only The different rope groove of rotation direction is provided on elevator wheel, rope can realize horizontal double-rope with the rotation of elevator wheel, this is specially Although benefit realizes double-rope, problem or it will be apparent that on the one hand the device double-rope can only reversed rope stretching, due to both ends Rope groove rotation direction difference cannot rope stretching in the same direction, also just need other pulleys to realize and promoted, this is without cost is increased, the on the other hand dress The area for setting occupancy is very big, installs and uses and has inconvenience.

Utility model content

In order to better solve the above problem, the utility model proposes a kind of rope can common rail hoisting mechanism, the machine Structure can avoid occurring the problems such as disorder cable, tangle in use process well not through rope winding jib, and can save use Space and use cost.

To achieve the above object, the utility model proposes a kind of rope can common rail hoisting mechanism, a kind of rope can be total to The hoisting mechanism of rail, including elevator wheel, the first rope, the second rope, balancing device, first rope are twined in elevator wheel one end Around rear, one end of the first rope connects balancing device, and the other end of the first rope is connect with weight to be gone up and down, and described second restricts Suo Yiduan is fixed on the elevator wheel other end, and the other end of the second rope is for going up and down weight.

Further, the helical form rope groove that axis is overlapped with elevator wheel axis, the first rope are provided on the elevator wheel The length of winding and rope groove accounts for the half of elevator wheel length in rope groove.

Further, the weight is promoted by the rope being wrapped on elevator wheel.

Further, first rope is only on elevator wheel along one circle of rope groove winding.Based on above scheme, this is practical new Type at least has the advantages that

1, it compared to the prior art, is greatly reduced using rope lengths, save the cost.

2, two ropes connect weight, are promoted more stable.

3, a rope for connecting weight is run with the rope common rail for connecting balancing device, therefore only needs two sections of rope grooves, Reduce elevator wheel length.

4, rope is not susceptible to disorder cable, tangles.Rope can common rail, and have always between the rope of two tractions certain Distance, so being not susceptible to entanglement etc..

5, structure is simple, and balancing device provides constant power to keep structure simple, and occupied area is small, is easy to use.

Specific embodiment

It is in the description of the present invention, it should be noted that term " center ", "upper", "lower", "left", "right", " perpendicular Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.In addition, term " the One ", " second ", " third " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.

In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary, It can be the connection inside two elements.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition The concrete meaning of language in the present invention.

Embodiment

As shown in Fig. 1 ~ 4, a kind of rope can common rail hoisting mechanism, including elevator wheel 3, the first rope 2, the second rope 4, Balancing device 1, the weight 5 to be gone up and down with balancing device 1 is connect respectively at both ends after first rope is wound on elevator wheel 3, Described second rope, 4 one end is fixed on the elevator wheel other end, and the other end of the second rope 4 is for going up and down weight.The elevator wheel 3 The upper helical form rope groove being overlapped provided with axis with 3 axis of elevator wheel, the rope groove is for accommodating the first rope 2, and the length of rope groove Degree accounts for the half of elevator wheel length, and first rope 2 is wrapped on elevator wheel only on elevator wheel 3 along one circle of rope groove winding The rope of close balancing device side leaves rope groove because of the rope closing of balancing device, does not move into the rope of elevator wheel also close to weight Rope, which synchronizes, moves into rope groove, since the first rope wiring one encloses, so rope groove must need to be arranged to guide its winding；In use, Balancing device 1 generates a constant force, and the rope being attached thereto is recycled, and rope, which is twitched, drives elevator wheel 3 to start turning, elevator Wheel rotation drives the second rope 4 to realize around the winding of elevator wheel to heavy lift, since the first rope mentions while going up and down weight Pulling force is supplied, so the mechanism need to only use two ropes that can reach effect, while 2 winding elevator wheels 3 one of the first rope Circle, and rope rope outlet direction it is different this with regard to the winding of very good solution rope, disorder cable the problem of, while connecting two of weight Rope is located at isometric elevator wheel two sides, ensure that lifting heavy is not in the process the different situation of lifting height.

The embodiment is most preferred embodiment, and a rope and balancing device rope common rail for weight is run, on the one hand greatly Ground reduces rope usage amount, because only needing two rope grooves, and the prior art will realize the just needs of more ropes connection to weight More ropes, every all needs range of lift length, so being in contrast to save rope usage amount, another aspect common rail Operation avoids well to be occurred tangling on elevator wheel and the phenomenon that disorder cable；Since the example structure is simple, elevator wheel Length and rope usage amount etc. are all few many compared with the prior art, and arrangement is facilitated to install, and are suitble to promote the use of.

Finally, it should be noted that it should be understood that the utility model described embodiment is only the utility model A part of the embodiment, rather than whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not having Every other embodiment obtained under the premise of creative work is made, is fallen within the protection scope of the utility model.

Unless otherwise defined, all technical and scientific terms used in this specification have with belonging to the utility model The identical meaning of the normally understood meaning of field those skilled in the art institute.
