Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and in particular to an elevator main frame. Background Art

[0002] The elevator drive unit is the component that drives the elevator to run or stop. The elevator drive unit is typically mounted on the mainframe (the drive unit's positioning component), which is in turn mounted on the load-bearing main and auxiliary beams (hereinafter referred to as the load-bearing beams). Under existing technology, the load-bearing beams are equipped with rope head plates (according to the national standard GB / T 7024, a rope head plate refers to a component that mounts a rope head assembly). Rope head plates are used to position and suspend the ropes or chains of the car suspension and counterweight suspension systems.

[0003] The relative shape and position tolerance between the rope head plate and the main frame is related to the smoothness and comfort of the elevator operation. If the error is too large, it will cause vibration and noise in the elevator car, and even cause wear and failure of related components.

[0004] Typically, rope end plates are designed and installed on the aforementioned load-bearing main beam or secondary beam, manufactured and installed separately from the main frame. However, because the load-bearing main beam or secondary beam needs to be connected to the building, and is subject to construction errors and construction conditions, its installation accuracy cannot meet design requirements. This may cause the position of the rope end assembly and the main frame, including the drive unit and car it supports, to deviate from the design value. If the deviation is too large, it will cause the elevator car to vibrate, make noise, and cause wear and failure of related components. Utility Model Content

[0005] Based on this, in order to solve the problem that the installation accuracy of the rope head plate is difficult to meet the design requirements, the utility model provides an elevator main frame, and its specific technical solution is as follows:

[0006] An elevator main frame comprises a frame body and a rope head mechanism; a driving main body is mounted on the top of the frame body, and a load-bearing beam is fixedly connected to the bottom of the frame body; the rope head mechanism comprises a suspension device and two groups of rope head assemblies symmetrically arranged on both sides of the top of the frame body, the rope head assembly comprises a rope head plate and a termination device, the rope head plate and the frame body are integrally formed, the termination device is mounted on the rope head plate, one end of the suspension device is fixedly connected to the elevator car, and the other end of the suspension device is respectively connected to the termination devices on both sides.

[0007] The above-mentioned elevator main frame is formed in one piece with the rope head plate and the frame body, which is conducive to improving the smoothness and comfort of the elevator car operation, reducing and minimizing the elevator vibration, noise and damage to related components caused by excessive shape and position tolerances of related components, and also reducing the workload of manufacturing, transportation and installation of related components, simplifying the production and installation workload, facilitating on-site quality control, and significantly improving project progress and efficiency.

[0008] Furthermore, the driving host is arranged between the two rope head assemblies and is used to control the lifting and lowering movement of the elevator car.

[0009] Furthermore, a connecting structure is provided on the load-bearing beam, and the connecting structure is fixedly plugged into the bottom of the frame body.

[0010] Furthermore, the load-bearing beam includes a main beam and a secondary beam, and both the main beam and the secondary beam are fixedly connected to the bottom of the frame body through the connecting structure.

[0011] Furthermore, the counterweight end of the suspension device is connected to the elevator counterweight via a set of pulleys.

[0012] Furthermore, the force center points of the two rope end plates are symmetrically arranged on both sides of the vertical plane of the midpoint of the line between the two termination devices.

[0013] Furthermore, the vertical plane formed by the suspension device coincides with the vertical section of the center of the elevator counterweight horizontal plane.

[0014] Furthermore, the two rope end plates are symmetrically arranged on both sides of the vertical cross-section at the center of the elevator counterweight horizontal plane.

[0015] Beneficial effects:

[0016] 1. The integrated design and production of the rope head plate and the main frame can ensure the accuracy of the relative position of the elevator counterweight, drive mainframe and elevator car, which is conducive to the smoothness and comfort of elevator operation, and reduces and minimizes the elevator vibration, noise and damage to related components caused by excessive shape and position tolerances of related components;

[0017] 2. The rope head plate and main frame are designed and manufactured in an integrated manner, eliminating the special load-bearing beam for the rope head plate required under existing technologies, saving the required steel and the corresponding civil engineering, burial, measurement, welding and other engineering workload;

[0018] 3. The design of elevators of the same specifications and models can greatly reduce the construction area of ​​the machine room and shaft, saving elevator installation costs for elevator users and increasing their use value;

[0019] 4. The integrated design and production of the rope head plate and the main frame reduces the workload of manufacturing, transportation and installation of related components, simplifies production, facilitates on-site quality control, and significantly improves project progress and efficiency.

[0020] 5. The integrated layout of the rope head plate and the main frame has higher overall strength and more uniform force than the layout of separate isolated components, making the elevator operation safer and more reliable. BRIEF DESCRIPTION OF THE DRAWINGS
