Abstract
Load reliever designed by the utility model, it is made up of fixed pulley group, bearing and drag-line, described fixed pulley group to be fixedly connected with two small trochal discs being symmetricly set on big trochal disc both sides by a big trochal disc and to form, three described wheel discs are coaxially arranged, and being fixed in the bearing of " Contraband " type, described big trochal disc is hollow-core construction, and described stay guy is fixedly connected on bearing, fixing after described activity guy cable rounds small trochal disc, big trochal disc is provided with suspension drag-line.The main feature of this structure is that middle big trochal disc is hollow wheel disc, reduces the effect of keeping out the wind of big trochal disc, reduces its vibration skew.
Description
Technical field
The utility model discloses a kind of load reliever, and it is the device transforming, have load alleviating function on the basis of common pulley, is mainly used in the load calculating of engineering structures.
Background technology
The eighties in 20th century, British scholar once proposed the concept of a kind of load calculating (Load Relieving System), and was applied to, in the soot of a cable net structure, attract attention.Although a lot of scholar conducts in-depth research load calculating afterwards, but it is also quite few to the load calculating really so far with practical value, reason is on the one hand difficult to construct simple load reliever efficiently, reason is that load calculating needs to ensure that the stress of component is no more than permissible stress by the displacement of releasing structure on the other hand, therefore it must combine with flexible structure, and engineering background has limitation.
From the above analysis, the research really with the load calculating of practical value is also quite few, and existing research lacks interdisciplinary intersection and fusion, does not fully excavate the potential of this system.Cause one of not strong reason of load calculating practicality to be that adopted reliever is more single, lack simple load calculating device efficiently, thus be difficult to realize applying of this kind of structural system on a large scale.Therefore, the research of load reliever is one of key issue of this kind of structure.
Utility model content
The purpose of this utility model is deficiency in order to solve above-mentioned technology and provides reliable, efficient, succinct load reliever.
In order to achieve the above object, load reliever designed by the utility model, it is by fixed pulley group, bearing and drag-line are formed, wherein drag-line comprises stay guy, movable drag-line and suspension drag-line, described fixed pulley group to be fixedly connected with two small trochal discs being symmetricly set on big trochal disc both sides by a big trochal disc and to form, three described wheel discs are coaxially arranged, and be fixed in the bearing of " Contraband " type, described big trochal disc is hollow-core construction, described stay guy is fixedly connected on bearing, fixing after described activity guy cable rounds small trochal disc, big trochal disc is provided with suspension drag-line.The main feature of this structure is that middle big trochal disc is hollow wheel disc, reduces the effect of keeping out the wind of big trochal disc, reduces its vibration skew.
In order to improve the weight bearing power of load reliever, described activity guy cable rounds small trochal disc is fixing after 1/4th weeks, and described suspension guy cable rounds big trochal disc is fixing after 1/4th weeks.
In order to reduce the cost of load reliever, described fixed pulley group is monoblock cast structure.
The load reliever that the utility model obtains, hang the weight of weight, the making a concerted effort and there is the linear ratio relation determined between the size of two wheel discs of small trochal disc drag-line, significantly can reduce the required weight weight hung when equal drag-line pulling force, there is the advantage that adjustable range is wide.Only contain a wheel disc in structure, form of structure is optimized greatly, and cost significantly reduces simultaneously, and constructability more, in addition, the wheel disc of load reliever is that monoblock cast forms, conduct oneself with dignity little, the power transmission efficiency between large small trochal disc is high, the good reliability of load reliever.

Fig. 2 is axonometric drawing of the present utility model.
Detailed description of the invention
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1.
As Fig. 1, shown in Fig. 2, the load reliever that the present embodiment describes, it is by fixed pulley group 1, bearing 2 and drag-line are formed, described fixed pulley group 1 to be fixedly connected with two small trochal discs 4 being symmetricly set on big trochal disc 3 both sides by a big trochal disc 3 and to form, three described wheel discs are coaxially arranged, and be fixed in the bearing 2 of " Contraband " type, described big trochal disc 3 is hollow-core construction, described stay guy 5 is fixedly connected on bearing 2, it is fixing after 1/4th four week that described movable drag-line 6 walks around small trochal disc, big trochal disc 3 is provided with and hangs drag-line 7, it is fixing after 1/3rd four week that suspension drag-line 7 walks around big trochal disc.Wherein said fixed pulley group 1 is monoblock cast structure.
Claims (3)
