Description
Technical field
A kind of counterweight rope hanging structure is the utility model is related to, particularly a kind of large-tonnage counterweight-side rope hanging structure.
Background technology
The weight balancing system of elevator is to ensure electricity typically by car, hoist ropes, counterweight and compensated chain composition, its effect
Ladder remains that traction-driven is steady in operation.Counterweight is the part that main balanced action is played in weight balancing system.It is right
Weight is hung in the side of hoist ropes with car.The weight of counterweight is the generally car depending on elevator nominal load capacity
Deadweight adds 50% nominal load capacity.Under this weight, the load difference of hoist ropes both sides becomes in a less scope
Change, so as to reach the purpose of elevator even running.
From above content, elevator payload ratings are bigger, and the weight of counterweight is bigger.Existing counterweight rope hanging structure is being answered
During to large-tonnage counterweight, the solution method of generally use has two kinds：First, the quantity of increase hoist ropes, returns rope sheave in this case
Thickness need widen, correspond to therewith, counterweight size and tunnel dimension are also required to widen；Second, the diameter of increase hoist ropes,
Increase is now needed to return the diameter of rope sheave, the diameter of traction sheave also increases therewith, and cost accordingly increases.Meanwhile because hoist ropes
Increasing number or diameter increase, the arrangement of fag end need more complicated Force Calculation, checked, and add the difficulty of fag end arrangement.
Therefore, the problem of existing large-tonnage counterweight rope hanging structure Existential Space requires high, and cost height is with fag end difficult arrangement.
Utility model content
The purpose of this utility model is, there is provided large-tonnage counterweight-side rope hanging structure.The utility model has space requirement
Low, cost is low and fag end arranges the characteristics of simple.
The technical solution of the utility model：Large-tonnage counterweight-side rope hanging structure, including counterweight, counterweight are provided with
Fixed seat, fixed seat are provided with two to returning to rope sheave, are provided with traction sheave to the top for returning to rope sheave, are arranged with and drag on traction sheave
Messenger group, hoist ropes group are divided into the first rope group and the second rope group, described the first rope group and the second rope group after laying out traction sheave
Respectively around corresponding to being fixed on after returning to rope sheave on rope head fixing device.
In foregoing large-tonnage counterweight-side rope hanging structure, counterweight guardrail, counterweight guardrail are provided with below described counterweight
Including main backplate, main backplate both ends are arranged with multigroup guard rail support, and guard rail support includes being fixed on counter weight guide track through pressing plate
On main side, described main backplate both ends are fixed on main side through angle steel；Described main side is provided with close to one end of car guide rail
The secondary of outside bending, secondary are provided with side backplate.
In foregoing large-tonnage counterweight-side rope hanging structure, it is described it is main while close to one end of well enclosure be provided with it is main while it is parallel
Side guard plate.
In foregoing large-tonnage counterweight-side lanyard mechanism, on described main backplate for angle cleat the first mounting hole,
Be used to connecting on angle steel it is main while the second mounting hole, the 3rd mounting hole that is used on guard rail support connecting pressing plate and while backplate on use
In connection secondary the 4th mounting hole be all waist-shaped hole.
Compared with prior art, the utility model is additionally arranged traction rope, and rope is divided into two strands, respectively by corresponding
To returning to rope sheave load.In this case, traction rope and extra design is not needed to change to returning to rope sheave
To load the counterweight of large-tonnage, this also implies that follow-up counterweight size and tunnel dimension need not all be widened.It is meanwhile per share
The rope quantity of rope group is close with the quantity of small tonnage counterweight lanyard, and also therefore lanyard fixing device passes through relatively simple calculating
Check and design.To sum up, the utility model has the characteristics of space requirement is low, and cost is low and fag end arrangement is simple.
In addition, the utility model is provided with counterweight guardrail in the lower end of counterweight operation area, and counterweight guardrail passes through guardrail
Main backplate, side backplate and side guard plate are connected and fixed on counter weight guide track by support and angle steel, and the structure had both avoided counterweight and led
Rail support and main guide rail, there is the characteristics of being easy to adjustment easy for installation again.
