Description

Knapsack formula elevator

Technical Field

The utility model relates to an elevator technical field especially is used for the knapsack formula elevator technique in villa elevator field.

Background

The backpack type elevator is commonly used for villa elevators, is a structure different from a conventional elevator, and is characterized in that the utilization rate of a shaft can be improved, the shaft with the same size has larger net area of a backpack type elevator car. However, the existing knapsack elevator still has obvious defects, and the main reason is that the car guide rails and the car suspension points are deviated to one side of the car knapsack, and the asymmetric arrangement mode causes an additional unbalance loading force which directly acts on the guide shoes, so that the guide shoes are seriously abraded, and the service life of the guide shoes is shortened. Therefore, it is very necessary to further optimize the specific structure of the rucksack elevator to improve the actual stress of the guide shoe.

Disclosure of Invention

The utility model aims at providing a knapsack formula elevator solves the skew too big problem of car focus of elevator car suspension point, has still adopted a brand-new guide rail arrangement mode in addition, further improves the well utilization ratio.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a knapsack formula elevator, includes car, spandrel girder, hauler, to heavily putting up, to heavy guide rail, rail brackets, car guide rail, knapsack frame and towline at least, its characterized in that: the backpack frame is fixed on the side wall C of the car, the car guide rail, the guide rail bracket, the counterweight guide rail and the counterweight frame are sequentially arranged on the inner side of the backpack frame from outside to inside, and the counterweight frame and the backpack frame do not interfere with each other when moving up and down along the counterweight guide rail and the car guide rail respectively; the distance from the center A of the lifting point on the car to the symmetrical center line of the car guide rail is L1, the distance from the symmetrical center line of the car guide rail to the side wall C) is L2, and L1 is more than or equal to L2.

Preferably, the counterweight guide rails and the car guide rails are fixed in a back-to-back manner on the guide rail brackets, and the guide rail brackets are located between the counterweight guide rails and the car guide rails.

Preferably, the backpack type elevator further comprises a counterweight sheave, a car top sheave, a first guide sheave and a second guide sheave, wherein one end of the traction rope is fixed on the bearing beam, then the traction rope sequentially bypasses the car top sheave, the first guide sheave, the second guide sheave, the traction machine and the counterweight sheave, and the other end of the traction rope is also fixed on the bearing beam.

Preferably, the hoisting rope is a steel belt or a steel wire rope.

Preferably, the center of gravity B of a combination body formed by the car and the backpack frame and the center a of a lifting point on the car are positioned on the same vertical line.

The utility model has the advantages that: under the structural form, the suspension point of the lift car is close to the gravity center of the lift car, so that the stress condition of the guide shoe is improved, and the lift car runs more stably; in addition, this structure has effectively practiced thrift the well space, has improved the utilization ratio of well.
