Technical Field
[0001] The utility model relates to the field of elevator installation, in particular to an adjusting structure for pre-installed guide rail brackets of a steel-frame elevator. Background Art
[0002] With the implementation of adding elevators to old residential areas, due to the narrow construction environment in old residential areas, the construction space for elevator installation is small, and there are great potential safety hazards in the stacking of elevator installation accessories during installation. The mode of pre-installing the whole elevator into the steel-frame shaft can solve this problem, which can not only reduce the on-site use space but also ensure the safety needs of the owners' travel; moreover, the elevator parts are pre-installed into the steel-frame shaft in the factory, saving the on-site installation time, and the installation construction in the factory can improve the efficiency and is safe and reliable. However, after the elevator is pre-installed into the steel-frame shaft, the perpendicularity of the elevator guide rail cannot be guaranteed in the factory, so on-site adjustment is required. The guide rail adjustment is mainly carried out in two directions: horizontal and vertical. Due to the limitation of the narrow shaft, especially when the shaft wall has uneven conditions such as concavity and convexity, it is particularly difficult for the operator to adjust the perpendicularity and horizontality of the guide rail bracket.
[0003] Therefore, the utility model provides an adjusting structure for pre-installed guide rail brackets of a steel-frame elevator to solve the above problems. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies existing in the prior art and provide an adjusting structure for pre-installed guide rail brackets of a steel-frame elevator, which can freely adjust the installation position of the guide rail in the horizontal and vertical directions.
[0005] The purpose of the utility model is achieved by the following technical solutions: This adjusting structure for pre-installed guide rail brackets of a steel-frame elevator includes:
[0006] Four columns are respectively arranged at the four corners of the elevator steel frame, and a number of cross beams are fixed between adjacent columns;
[0007] Guide rail brackets are correspondingly arranged on the inner side of each cross beam on one side of the elevator steel frame;
[0008] Guide rails are adjustably installed on each guide rail bracket in the horizontal direction through a horizontal adjusting component; and
[0009] Main brackets are arranged at both ends of each guide rail bracket, and one end of the main bracket is fixedly installed on the cross beam, and the other end of the main bracket is adjustably connected to the guide rail bracket in the vertical direction through a vertical adjusting component.
[0010] As a further technical solution, the horizontal adjusting component includes a pressure guide plate and a horizontal long circular hole opened on the guide rail bracket. The guide rail is fixed by being clamped into the pressure guide plate, and the pressure guide plate is matched with the horizontal long circular hole through a horizontal adjusting bolt, so as to adjust the installation position of the guide rail relative to the elevator steel frame in the horizontal direction.
[0011] As a further technical solution, the vertical adjustment component includes a vertical adjustment bolt. Fixing holes and vertical oblong holes are formed in the guide rail bracket, and corresponding fixing holes and vertical oblong holes are also formed in the main bracket. The vertical adjustment bolt adjusts the installation position of the guide rail relative to the elevator steel frame in the vertical direction through the fixing holes and the vertical oblong holes.
[0012] As a further technical solution, a bracket bottom plate is fixedly welded to the end of the main bracket, and a positioning hole is formed in the bracket bottom plate; a positioning plate is fixed at a position corresponding to the bracket bottom plate on the cross beam, and a positioning pin is provided on the positioning plate.
