Description

Technical Field

[0001] The invention relates to the technical field of verticality measurement, and in particular to a verticality detection device installed in an elevator. Background Art

[0002] As an important part of the elevator, the elevator guide rail is an important factor affecting safety and comfort. The elevator guide rails have undergone strict quality inspections before leaving the factory, and the manufacturing errors have been controlled within a relatively ideal range. Therefore, the installation errors generated during the installation process become a factor affecting the final quality level of the elevator guide rails. There are many types of guide rails. The most widely used one is the standardized steel structure guide rail. The single length is generally 3-5m. During installation, several guide rails are vertically spliced ​​according to the height of the building. Among them, excessive deviation of the verticality of the guide rail will cause the elevator to swing and bump during operation. Therefore, the verticality of the guide rail needs to be checked when installing the guide rail to ensure that the verticality deviation of the guide rail is controlled within the standard range.

[0003] After searching, the Chinese patent publication number CN216523900U discloses an elevator installation verticality detection device; it can assist in the detection of the verticality of the elevator car, is easy to disassemble and install, improves the verticality detection accuracy of the elevator car and improves the detection efficiency; it includes two sets of clamping parts, a main frame, a spiral bevel gear steering box, two sets of transmission screws, a gravity line bob and a dial, the spiral bevel gear steering box is embedded and installed in the main frame, the two sets of transmission screws are rotatably installed on the left and right parts of the main frame, and the two sets of transmission screws are fixedly connected to the left and right output ends of the spiral bevel gear steering box; although the device can first be fixed to the top and then the drop-out line can be moved to the vicinity of the rail for inspection according to the single rail to be inspected.
