Indirect Drive Traction Elevator
Patent No.: 2006201534312
Traditional Dray-lift by Dray through Dray-oriented round by round and the hoisting rope Cabin, the weight and balance chain (or balance rope), composed of transmission mechanism, through Dray Dray-round with a rope Friction, the provision of adequate Dray of the direct-drive Car move up or down.
First, the traditional Dray of the force:
1, provided hoisted Cabin, the weight, rope, chain balance (or balance rope) suspension system, such as the bearing capacity
2, to provide sufficient torque so that the whole of the suspension system, the delivery of mobile customers
Second, the traditional Dray of the unfavorable factors:
1. Dray machine design, these two factors to be considered:
1.1 Dray of the main straight will be relatively large;
1.2 Dray Machine will be the main straight Cabin forces, movements such factors as changes in the itinerary of the impact (in practice often decorated weight increased, from increased movements trip wire rope or chain balance balance the weight of justice to the impact of the increase Dray Machine Spindle by the carrying capacity so that a certain type of machine can not Dray more flexibility to meet changing requirements, to a greater allocation of Dray.)
1.3 Dray-volume, larger than the consumption of materials.
1.4 Dray confidential to provide adequate Dray, and rope in the rope round will have enough on the corners, this will enable the hoisting rope hanging from the core subject to certain restrictions;
2. Dray of the traditional structure of direct-drive Car Dray, is inevitable:
2.1 Dray of direct transmission of vibration to the Cabin:
2.2 Cabin noise within the relatively large (especially high-speed elevator).
Here are the traditional design of a new elevator - indirect drivers Dray Elevator
Third, indirect drivers Dray lift the design breakthrough
1, design ideas: Dray lift Dray of two major factors (that is provided by the hoisting of the + set to provide sufficient torque), be considered separately into consideration, a new type of indirect drivers Dray lift programme, that is drag Reply traditional structures were hoisted and Dray part of the drive.
2, layout structure: the traditional indirect drivers Car driven into indirectly (that is, some hoisting + Dray drive).
Features: a, with the hoisting of the separate parts of Dray driver settings.
b, hoisted by some of the Cabin from the weight, balance chain (or balance rope) the main rope. Accompanied by the hoisting of the cable radial force.
c, Dray driven by the part of the whole suspension system, the movement of torque.
d, Dray driver of the rope rate. According to different specifications of the models can be designed to lift n: 1 general use even.
e, part of the hoisting rope 1:1 ratio.
f, fixed pulley, static pulley wheel axle into a parallel group interval layout.
3. Story structure and composition: (abbreviated)
In order to provide Dray, and both sides must Afterburner round Dray, Dray rope system must be designed as a closed-loop system and increase tension, and closed-loop system because of the rope Dray rope with the passage of time will be stretching, The system to ensure tension at the same time to ensure that compensation for the rope length of wire rope, rope in the spring or designed as a lever tensioning device (or at the bottom of the wells along).
4, indirect advantage of the lift drive Dray Machine
1. As indirect drivers, elevator car is its very low noise of the biggest bright spots, particularly the high-speed elevators.
2. Elevator car weight on Dray does not affect the ability of Dray.
2.1 elevator in the elevator decorative users have a greater degree of freedom.
2.2 elevator car can achieve the lightest of the traditional Dray Dray ability to ensure the elevator, elevator car must be designed to be heavy enough, but such a lift for the Cabin lightweight design and application of new materials to provide a broad Prospects.
3. Dray Machine spindle bearing capacity low, Dray machine can be relatively small.
4. Dray machines almost from the impact of increasing movements itinerary.
5. Road layout in the elevator shaft has become very flexible so that the bed ladder, particularly non-standard tourism staircase lift simple layout design (traditional Dray Machine-lift capacity in order to ensure Dray must meet certain corners and a certain suspension hanging Core Distance, such elevator hoisted hanging from the core unrestricted)
6. Such elevators can be flexible room layout, Dray Machine host and the re -
6.1 engine room layout: at home, or under the home side
6.2 Dray machine in the engine room, layout: the re-arrangement in the left or the right
6.3 pairs Well Road in the layout: Cabin layout in the back, left or right
6.4 Cabin and in particular the re-arrangement may be in different space Well Road
Indirectly drive low-noise lift its distinctive features, but there are also shortcomings, and that is to increase the workload of the installation, commissioning adjustment of the increase in workload, but because of their inherent characteristics, there are broad prospects, in order to enhance the operation of the lift Quality, and provide a viable package of solutions, both the passenger elevator, medical elevator, escalator beds, Huoti can use this new programme to address. To focus on targeting the most advanced technology and the elevator control permanent magnet synchronous Dray-host, so that the new elevator-energy saving, environmental protection, low noise, and other advantages in a
