Description

Technical Field

[0001] This utility model belongs to the field of elevator equipment technology and relates to an elevator with variable load capacity. Background Technology

[0002] With economic development, elevators are becoming increasingly common. As a modern mechanical transportation tool, elevators have become an indispensable piece of equipment in factories.

[0003] Freight elevators are primarily designed for transporting goods and are usually staffed. Freight elevator cars are characterized by their long and narrow shape. They are vertical lifts powered by electric motors and equipped with box-shaped cabins. They are fixed lifting devices serving designated floors, consisting of a single car that runs between at least two vertical, rigid guide rails.

[0004] With industrial development, industrial plants and workshops are extending to higher floors, creating new demands for the occasional transport of extra-large industrial equipment and materials to higher floors. Current solutions often involve designing and installing various heavy-duty elevators. However, such heavy-duty transport needs may only occur occasionally, often resulting in overkill for these elevators, high transportation costs, poor economic efficiency, and low utilization efficiency.

[0005] Therefore, a variable load elevator is designed to overcome the above problems. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a variable load elevator with a simple and reasonable structure and stable operation.

[0007] This utility model is achieved through the following technical solution: a variable load elevator, including an elevator and a counterweight device. The elevator car is a car frame composed of an upper car frame, a lower car frame, and straight car frame beams on both sides of the upper and lower car frame. It is connected to the counterweight device through a wire rope winding ratio module. The upper car frame consists of two parallel pieces, namely a first upper car frame and a second lower upper car frame. The lower car frame is a single piece. An upper car top wheel is installed under the first upper car frame, and a lower car top wheel is installed under the second lower upper car frame. A mounting base is provided between the first upper car frame and the second lower upper car frame. A car anti-rope wheel is installed on the mounting base. A wire rope winding ratio module is provided on the car anti-rope wheel. One end of the wire rope winding ratio module is connected to the car frame, and the other end realizes the lifting and lowering of the elevator through the wire rope winding ratio module. The counterweight device consists of at least two vertically arranged counterweight frames. The two vertically arranged counterweight frames are detachably connected to realize the adjustment of the load.

[0008] Preferably, the counterweight frame of the counterweight device is a frame structure composed of an upper counterweight beam, a lower counterweight beam, and a straight counterweight beam. Multiple counterweight blocks are installed inside the frame structure, and a left counterweight wheel and a right counterweight wheel are arranged on the lower left and right sides of the upper counterweight beam.

[0009] Preferably, the wire rope winding module includes a wire rope and an elevator main unit. The elevator main unit is installed on the top of the car frame. Two wire ropes are suspended on the elevator main unit. One wire rope passes through the guide wheel and then passes through the lower car top wheel, the car counter-rope wheel, and the upper car top wheel in sequence before being fixed to the car rope head plate in the elevator shaft. The other wire rope passes through the left counterweight wheel, the counterweight counter-rope wheel, and the right counterweight wheel in sequence before being fixed to the counterweight rope head plate in the elevator shaft.

[0010] Preferably, the diameter of the lower car top pulley is larger than that of the upper car top pulley, and the diameter of the car anti-rope pulley is between that of the lower car top pulley and the upper car top pulley, in order to ensure that the two wire ropes are perpendicular and do not interfere with each other.

[0011] Preferably, a buffer is provided at the bottom of the counterweight frame, and a corresponding buffer base is provided at the bottom of the elevator shaft to improve overall safety.

[0012] The beneficial effects of this utility model are as follows: This utility model designs a variable load elevator with two full-load capacities, allowing for the maximum load capacity based on usage requirements. It also features two vertically arranged counterweight sections. The lower counterweight section can be connected to or detached from the upper counterweight section as needed to accommodate different load capacities. A motor can be installed on the lower counterweight section to automatically connect or detach from the upper counterweight section, enabling rapid load switching. Attached Figure Description
