Description

TECHNICAL FIELD

[0001] The present application relates to the elevator technical field, especially to a new type of rear counterweight elevator structure. BACKGROUND

[0002] With the development of industry, automatic logistics equipment is also more and more popular, and the demand for vertical elevators is also more and more. Customers' requirements for the size and price of the elevator are also more and more stringent. In the prior art, the standard elevator structure, because the counterweight system occupies the width space of the shaft, reduces the utilization rate of the shaft, therefore, the elevator car is generally a special wide car, the upper beam length on the car frame is very long, and in a normal case, the strength of the upper beam meets the demand, and the deflection exceeds the fixed range value. In order to reduce the deflection, a large specification type steel is usually used, but it often causes waste of materials and greatly increases the production cost. In addition, the length of the counterweight system is also limited due to the influence of the shaft depth CD value. Generally, in the case of large load, a steel plate counterweight block needs to be configured. And with the lengthening of the counterweight system, the length of the counterweight rail fixing piece also needs to be lengthened. In order to make the strength and deflection meet the requirements, a large size profile is usually configured. The above two kinds increase the material production cost and reduce the enterprise's profit.

[0003] In order to solve the above problems, the present application discloses a new type of rear counterweight elevator. Practical new type
