Background
With the rapid development of the elevator industry, various elevators bring great changes to the lives of people. High efficiency, high speed, stability, low noise and safe operation have become the fundamental requirements of people on elevators. As is well known, since an elevator is used as a vertical transportation means for carrying people to move up and down, because people can walk freely in a car, uneven load in the car is inevitable, the elevator design generally considers the influence of rated load on the operation comfort of the elevator, and elevator manufacturers adopt a series of methods to reduce the adverse effect caused by unbalanced load generated by rated load. However, the center of gravity of an empty car (including a car frame), the running guide center of the car and the suspension center of the car guide wheel are not coincident, so that problems which are difficult to solve are caused, such as the phenomenon of poor riding comfort, high running noise, large running vibration in the car, and the like. Therefore, when the elevator scheme is designed, the three-in-one effect is achieved as much as possible.
The design of the elevator arrangement structure mainly considers that the front side of the car is hung with a door machine, a car door, an operation box in the car and other parts, compared with the back side car wall, the quality is larger, especially when the car door is made of glass, the traditional technical scheme adopts the car guide rail to move forwards for a certain distance, so that the car guide system and the gravity center of the empty car are ensured to be close to each other as much as possible, but the scheme can only estimate the positions of the car operation guide center and the gravity center of the empty car according to design experience, and the serialization workload under different car specifications is large, the specification types are multiple, and the production is easy to be confused to make mistakes.
Another more conventional approach is: the balance iron is hung at the bottom of the car to balance the unbalance loading effect generated by the front side weight of the car, but the scheme has the defects that: 1. the design quality of the lift car is increased, the weight is increased, and the cost is increased; 2. the system quality is increased, and the requirements on a traction machine and a steel wire rope are increased; 3. if the unbalance loading is large, the number of suspended balance irons at the car bottom is increased, and the requirements on the car bottom are increased, including the requirements on spatial position, stress strength and the like.

In order to achieve the above object, the utility model provides an elevator arrangement structure, include the car, to heavy guide rail, car guide rail, tow wire rope, car fag end subassembly and to heavy fag end subassembly, the line of two sets of guide rail working face central points of car guide rail is the Y axis, and is perpendicular the Y axis just passes the central line of car is the X axis, still includes a set of to heavy rope sheave subassembly, first group car rope sheave subassembly, second group car rope sheave subassembly and a set of subassembly of towing, to heavy rope sheave subassembly, first group car rope sheave subassembly, second group car rope sheave subassembly and tow the equal symmetrical arrangement of driving sheave subassembly in the both sides of Y axis, car fag end subassembly with to heavy fag end subassembly all about Y axis symmetrical arrangement, tow wire rope has two sets ofly.
Advantageously, the first set of car sheave assemblies, the second set of car sheave assemblies are located at the bottom or top of the car.
Preferably, the two sets of traction steel ropes symmetrically arranged about the Y axis start from the car rope assembly, pass through the first set of car rope pulley assembly downward, pass through the second set of car rope pulley assembly horizontally, pass through the traction wheel assembly upward, pass through the counterweight rope pulley assembly downward, and finally are fixed on the counterweight rope assembly upward.
Preferably, the counterweight sheave assembly is located in a projection plane directly below the traction sheave assembly and coincides with a tangent line of the traction sheave assembly in a left-side vertical direction.
Preferably, the traction wheel assemblies are symmetrically arranged at two ends of an elevator traction machine, the elevator traction machine is fixed through a fixing frame, and the counterweight rope head assembly is mounted on the fixing frame of the traction machine.
Preferably, the traction wheel assemblies are symmetrically arranged at two ends of an elevator traction machine, and the traction machine is arranged on the counterweight guide rail or a machine isolating beam fixed in a hoistway.
The utility model provides a pair of novel elevator arrangement structure adopts two wire rope arrangement structure that tow, the symmetrical arrangement in the suspension rope of car guide both sides makes suspension point center and the coincidence of car guide center nature, through the analog computation, guarantees that empty car weight is located near Y axle, can realize the aforesaid "three-in-one", very big optimization product design process, improved the elevator and born the unbalance loading ability of limit load, guaranteed the comfort of elevator operation, practiced thrift the development cost of elevator product.
