Problems solved by technology

[0005] The purpose of the present invention is to provide a mechanical self-leveling device and method to solve the problem that the cage cannot maintain a horizontal state for safe operation when the curvature of the guide rail frame changes. The meshing force generated by the automatic meshing with the chain drives the transmission shaft to rotate, realizes the speed change through the gearbox and changes the transmission direction through the universal joint, and automatically adjusts the angle between the vertical centerline of the cage and the centerline of the guide rail frame to ensure that the elevator is in operation. The cage is always running horizontally

Embodiment 1

[0038] Such as Figure 5-8 As shown, this embodiment provides a mechanical self-leveling device. According to the use requirements, a chain 3 of a certain length is pre-installed through a fixed bracket 4 in the area of ​​the guide rail frame 1 where the running state of the cage needs to be adjusted, and the transmission shaft 5 is installed on a safe On the seat plate 12, a sprocket 2 is installed on one end of the transmission shaft 5, and the other end of the transmission shaft 5 is connected with the universal joint 8 through bolts, and the speed conversion is performed through the gearbox 6 in the middle, and the universal joint 8 and the lead screw 9 pass through The bolts are connected, and the end of the leading screw 9 is designed with an emergency leveling handle 11. When an unexpected situation occurs and the leveling handle 11 cannot be normally leveled, manual leveling can be achieved by manually turning the leveling handle 11. Gear box 6 is fixed on the cage top...

Abstract

The invention discloses a mechanical self-leveling device and method, which relate to the technical field of leveling devices and may include a chain, a sprocket, a transmission shaft, a universal joint and a lead screw; the chain is installed on a rail frame, and the chain The wheel is installed on one end of the transmission shaft, and the sprocket is engaged with the chain; the transmission shaft is installed on the seat plate of the safety device, and the other end of the transmission shaft is connected to the universal joint, and the universal joint Sections are also connected with the lead screw. In the present invention, the chain is pre-installed at the position of the guide rail frame that needs to be leveled, the meshing force generated by the automatic meshing of the sprocket and the chain drives the transmission shaft to rotate, the speed conversion is realized through the gearbox and the transmission direction is changed through the universal joint, and the vertical adjustment of the cage is automatically adjusted. The angle between the straight centerline and the centerline of the guide rail frame ensures that the cage is always running in a horizontal state during the operation of the elevator.

Description

technical field [0001] The invention relates to the technical field of leveling devices, in particular to a mechanical self-leveling device and method. Background technique [0002] As a vertical transportation machine for transporting personnel and materials in construction projects, construction elevators, with the continuous development of building shapes, the original linear guide rail frame can no longer meet the needs of the project, and more and more occasions need to install curved rails Guide rail frame, in order to ensure the safety of personnel and goods, technical measures should be taken to ensure the horizontal operation of the cage. [0003] Existing methods such as Figure 1-4 As shown: the reducer 3 is installed on the support 4, the support 2 on the load-bearing frame 1 and the support 2 6 on the cage 8 are connected together through the support 4, and the end of the reducer 3 is installed with a coupling 5, When leveling is required, the driving force pro...
