Description

Technical Field

[0001] This utility model relates to elevators, specifically to a beam lifting mechanism. Background Technology

[0002] With rapid societal development, land is becoming increasingly scarce, and the phenomenon of "every inch of land is worth its weight in gold" is commonplace in modern cities. The same applies to elevators; finding ways to make shafts smaller and elevators larger is a growing and increasingly important requirement given the ever-increasing value of land. For example, conventional elevators already in operation on the market have ample dimensional allowances in all dimensions, rather than adhering to the limits required by national standards.

[0003] Currently, the design, manufacturing, and installation of elevators do not involve the same high level of technological requirements as automobiles. We often allow for larger tolerances to reduce various processing and installation problems and difficulties. However, this requirement is more urgent for home elevators because the shaft space is very small. Maximizing the car size is a pressing need for every manufacturer. Therefore, it is necessary to optimize the upper beam lifting structure of home elevators. To this end, we propose an upper beam lifting mechanism. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an upper beam lifting mechanism, which solves the problem that the existing home elevator shaft space is very small, and maximizing the car size is an urgent need for every manufacturer, requiring optimization of the upper beam lifting structure of home elevators.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a beam lifting mechanism, including a crossbeam, a connecting plate, a mounting plate, a rotating shaft, a connecting rod, a lifting plate, a positioning screw one, a positioning screw two, and a cover plate. Two crossbeams are provided, and the two crossbeams are fixedly connected by the connecting plate. A cover plate is fixedly connected above the crossbeams. Two mounting plates are symmetrically fixedly connected to the front side of the front of the front crossbeams. A rotating shaft is rotatably connected to the front end of each of the two mounting plates. A connecting rod is fixedly connected between the inner ends of the two rotating shafts. A lifting plate is fixedly connected to the outer ends of the two rotating shafts. The right rotating shaft is located outside the mounting plate and is fixedly connected to the positioning screw two by a thread. The right mounting plate is connected to the positioning screw one, which cooperates with the positioning screw two, by a thread.

[0006] Based on the above scheme, two connecting plates are provided, and the two connecting plates are fixedly connected to the inner sides of both ends of the two crossbeams by bolts.

[0007] Based on the above scheme, a reinforcing plate is fixedly connected to the middle of the inner side of the two crossbeams by bolts.

[0008] Based on the above scheme, there are two cover plates, which are respectively fixedly connected to the two ends above the two crossbeams by bolts.

[0009] Compared with the prior art, the advantages of this utility model are as follows: A new structure is adopted for the upper beam lifting mechanism of a home elevator. Without changing the comfort of elevator operation, it meets the requirements of a smaller top floor. The linkage mechanism is modified to improve the synchronization of the left and right safety clamp lifting plates. The structure is simple and minimizes the top floor requirement. This utility model has a simple and reasonable structure, is easy to install and use, has high synchronization, low manufacturing cost, and strong practicality. Attached Figure Description

A lifting plate 7 is fixedly connected to the outer ends of each of the two rotating shafts 5. The two lifting plates 7 can achieve synchronous lifting through the connection of the two rotating shafts 5 and the connecting rod 6. The rotating shaft 5 on the right side is located outside the mounting plate 4 and is fixedly connected to the positioning screw 2 9 by a thread. The mounting plate 4 on the right side is connected to the positioning screw 1 8, which cooperates with the positioning screw 2 9.

[0017] The principle and advantages of this utility model: A new structure for the upper beam lifting mechanism of a home elevator is adopted, which optimizes the upper beam lifting mechanism without changing the elevator's operating comfort. It meets the requirements of a smaller top floor by modifying the linkage mechanism and setting two lifting plates 7, which are connected by two rotating shafts 5 and connecting rods 6, so that the two lifting plates 7 can be lifted synchronously. This improves the synchronization of the left and right safety clamp lifting plates 7. The structure is simple and minimizes the top floor requirement.
