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, it is the counterweight system for elevator of 4:1 that a kind of traction ratio that can greatly reduce the size that focuses on the shaft depth direction is provided, even to reach with traditional traction ratio be that the situation of 2:1 is identical, thereby making the 4:1 towed elevator can adopt traction ratio is that the elevator of 2:1 is in the structural design of hoistway and can realize that with traction ratio be that the elevator of 2:1 is basic identical on the hoistway sectional dimension, the design is specially adapted to require to adopt rear opening car and the less elevator situation of shaft depth size, the counterweight frame of pair weight simplifies the structure simultaneously, and cost is lower.
The technical solution of the utility model is, the utility model traction ratio is the counterweight system for elevator of 4:1, it comprises the 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 is 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, the axis of the axis of described the first counterweight diversion sheave and the second counterweight diversion sheave is located along the same line, this straight line is positioned at horizontal surface, and this straight line and the projection line of counter weight guide track line of centers in horizontal surface are in a certain angle, this angle span is closed interval [45 °, 90 °].
After adopting said structure, the utility model compared with prior art, have the following advantages: because the axis of the first counterweight diversion sheave and the axis of the second counterweight diversion sheave are located along the same line, this straight line is positioned at horizontal surface, and this straight line and the projection line of counter weight guide track line of centers in horizontal surface are in a certain angle, this angle span is [45 ° of closed intervals, 90 °], like this, watch along described rectilinear direction, the first counterweight diversion sheave and the second counterweight diversion sheave be state in an overlapping, so that pair weight can reduce to minimum along the size of shaft depth direction, this will directly cause can reducing to minimum for the size of counter weight guide track frame on the shaft depth direction that pair weight is installed, the design has realized greatly reducing pair weight in the purpose of the size of shaft depth direction, thereby so that the design is specially adapted to require to adopt rear opening car and the less elevator situation of shaft depth size, the counterweight frame of pair weight simplifies the structure simultaneously, and cost is lower.
As improvement, described the first counterweight diversion sheave and the second counterweight diversion sheave are arranged in the same rotating shaft, and this rotating shaft is installed on the pair weight, like this, more are conducive to simplify the structure of counterweight system, reduce and produce and the working service cost.
As improvement, the adjacent layout with the second counterweight diversion sheave of described the first counterweight diversion sheave like this, more is conducive to reduce the first counterweight diversion sheave and the second counterweight diversion sheave shared space on axis direction.
