Description

Technical Field

[0001] The utility model relates to the technical field of household elevators, in particular to a top-hanging household elevator. Background Art

[0002] Elevators are generally used for up and down stairs transportation in high-rise buildings. They can be divided into bottom-supported and top-suspended types. In most usage environments, both can be used for both passenger and freight transportation, and have the advantages of small footprint and low cost. In the field of home elevators, the bottom-supported type has more structural components at the bottom of the elevator car, so a deeper pit is required for installation. In a home environment, many pipelines are often arranged under the ground, which is not conducive to the installation of bottom-supported elevators. Therefore, home elevators are often top-suspended elevators. However, most home elevator devices need to occupy part of the shaft space due to the presence of a counterweight to balance the weight of the car and reduce the burden on the traction machine. The area available for the elevator is squeezed and reduced, forcing users to choose a smaller elevator or increase the shaft area. Reducing the elevator area will affect the user experience, and increasing the shaft area will encroach on the original residential area. Utility Model Content

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional home elevator device, there is a counterweight to balance the weight of the car and reduce the burden of the traction machine, which requires occupying part of the hoistway space. The area available for the elevator is squeezed and reduced, forcing users to choose a smaller elevator or increase the hoistway area. Reducing the elevator area will affect the user experience, and increasing the hoistway area will occupy the original residential area. This device cancels the counterweight, sets a movable pulley block and increases the number of traction machines to share the load of the traction machine, reducing the waste of hoistway space;

[0014] 2. During the use of the elevator, the weight of the car is transferred to the lower fixed beam through the upper beam, and then to the movable pulley through the lower fixed beam, and then dispersed by the cable and transferred to the upper fixed beam and the guide wheel. At the same time, part of the load is also transferred to the traction wheel. The load of the upper fixed beam is borne by the top beam, and the load of the guide wheel is borne by the guide fixed seat and transferred to the support plate, and then borne by the top beam. The load of the traction wheel is borne by the traction fixed seat and then borne by the top beam, so as to achieve the elimination of counterweight without increasing the load of the traction machine, so as to solve the problem of the traditional home elevator device that the counterweight occupies the shaft space and reduce the waste of shaft space;

[0015] 3. When the elevator is rising or falling, the motor drives the traction wheel to rotate, which drives the cable to move. The cable is guided by the guide wheel to drive the fixed pulley and the movable pulley to rotate, which drives the upper beam to move, thereby driving the lower beam and the connecting column to move, and finally the car is raised or lowered. The setting of two motors allows the device to start scaling from both ends of the cable at the same time, solving the problem that the pulley group needs to move the cable a longer distance to obtain the same lifting distance as the traditional top-hanging elevator, thus ensuring the normal use of the device.
