Description
Technical field
The utility model relates to the counterweight system for elevator technical field, specifically is that a kind of traction ratio is the counterweight system for elevator of 4:1.
Background technology
Counterweight system for elevator also is referred to as elevator equilibrium system, it is one of indispensable vitals of modern traction elevator, the radical function of this system is the weight of relative equilibrium cage side, weight difference between car and counterweight is remained within the limit, guarantee that the traction-driven of elevator normally reaches the safety of elevator, because its importance, the design arrangement of counterweight also becomes one of key areas in the elevator system design.
For the elevator that traction ratio is 4:1, because the inherent characteristics of self, there are significantly difference in its counterweight and traditional elevator, are called such as name: elevator counterweight, its counterweight mainly by the counter weight guide track frame, to pouring weight, lead boots, buffer head forms.Have another name called and be called: a kind of Novel elevator counterweight device, its traction ratio are the counterweight system for elevator of 4:1, but counterweight diversion sheave needs 3 and the distribution of one-tenth " product " font.
The above-mentioned deficiency of proposing design is, the former elevator counterweight is not suitable for the elevator of 4:1 traction ratio, a kind of structure of design of Novel elevator counterweight device is complicated, cost is higher, and (described shaft depth refers in the hoistway birds-eye view shaft depth, hoistway is perpendicular to the length of this side of elevator door, that is to say, in the length that has perpendicular to this direction hoistway of elevator door) require greatly, quite different with aspects such as traditional having machine room 2:1 traction ratio elevator is boxed out at machine room, bearing beam layouts, commonality is not strong.
The utility model content
The technical problems to be solved in the utility model is, provide a kind of and reduce focusing on the size of shaft depth direction, thereby be specially adapted to that 4:1 traction car rear opening is arranged or the traction ratio of the elevator that the 4:1 traction car hoistway degree of depth is little is the counterweight system for elevator of 4:1.
The technical solution of the utility model is, the utility model traction ratio is the counterweight system for elevator of 4:1, it comprises counterweight track adjusting wheel, the first counterweight diversion sheave, the second counterweight diversion sheave and pair weight, the first counterweight diversion sheave, the second counterweight diversion sheave are installed on the pair weight, hoist ropes enters from the first counterweight diversion sheave, again via described counterweight track adjusting wheel, go out and be connected to fixedly fag end to the second counterweight diversion sheave, described fixedly fag end is between the second counterweight diversion sheave and counterweight track adjusting wheel, and described fixedly fag end is arranged in the downward projection of counterweight track adjusting wheel.
After adopting said structure, the utility model compared with prior art, have the following advantages: on the one hand, because described fixedly fag end is between the second counterweight diversion sheave and counterweight track adjusting wheel, and described fixedly fag end is arranged in the downward projection of counterweight track adjusting wheel, like this, the axis of the axis of the first counterweight diversion sheave and the second counterweight diversion sheave each other can be more close, because the mutual distance of the axis of the axis of the first counterweight diversion sheave and the second counterweight diversion sheave is less, just do not need to arrange along the larger-size pair weight of shaft depth direction the first counterweight diversion sheave and the second counterweight diversion sheave are installed, this will directly cause pair weight less along the size of shaft depth direction, pair weight can be less for the size of counter weight guide track frame on the shaft depth direction that pair weight is installed along less the causing of size of shaft depth direction, on the other hand, after going out, described hoist ropes to the second counterweight diversion sheave is connected to described fixedly fag end, and described fixedly fag end is arranged in the downward projection of counterweight track adjusting wheel, make described counterweight system for elevator reach (shown in Fig. 2 birds-eye view, this direction is the reach direction from bottom to top, the elevator door of top is the Qianmen among the figure, the elevator door of below is the back door), thereby therefore effectively reduced counterweight center and car backbone off centering distance and reduced the required space requirement of elevator layout, because described counterweight system for elevator reach, when but actv. is avoided counterweight system for elevator and car rear opening the back door machine interfere and shaft depth than situation that hour can't mounting arrangements, comprehensively above-mentioned, the design has realized greatly reducing the purpose to the size that focuses on the shaft depth direction, thereby so that the design is specially adapted to 4:1 traction car rear opening arranges or the little elevator of the 4:1 traction car hoistway degree of depth.
As improvement, described the second counterweight diversion sheave is arranged in the downward projection of counterweight track adjusting wheel, and like this, the structure of whole counterweight system for elevator will be compacter.
