Embodiment 1

[0033] As shown in the accompanying drawings, an installation measuring tool for the sill of an elevator landing is characterized in that it includes two sets of mirror-symmetrical measuring rods 1, a machine base 2 and a hoistway guide rail 5 that is adjustably connected to the machine base 2; The base 2 is adjustably fixed to the measuring rod 1; one end of the measuring rod 1 is provided with a limiting positioning plate 3 and a fastening positioning plate 4; the limiting positioning plate 3 and the fastening positioning plate 4 are connected to the The measuring rod 1 is adjusted to fit and connect. The cross section of the measuring rod 1 is L-shaped; the measuring rod 1 includes a bottom edge 11 and a vertical edge 12 , the limit positioning plate 3 is arranged on the upper surface of the bottom edge 11 ; the fastening positioning plate 4 is arranged on the vertical edge 12 . The bottom edge 11 and the position-limiting plate 3 are respectively provided with slots and bo...

Embodiment 2

[0038] The difference from Embodiment 1 is that a scale is provided on the measuring rod 1, and a straightedge is set between the front end of the measuring rod 1 and the limit positioning plate 3 and in the approximate range where the middle section of the measuring rod 1 and the machine base 2 are fixed. It is fixedly connected with measuring rod 1.

Abstract

The invention belongs to the field of installation measurement tools, and especially relates to an installation measurement tool for elevator landing sill. The installation measurement tool comprises two groups of measurement rods in mirror symmetry, a pedestal, and a well guide rail adjustably connected with the pedestal, wherein the pedestal is adjustably fixed to the measurement rods; one end of each measurement rod is provided with a limiting locating plate and a fastening locating plate which are in adjustable fit connection with the measurement rod. The measurement rod has an L-shaped cross section and comprises a bottom side and a vertical side, the limiting locating plate is arranged on the upper surface of the bottom side; and the fastening locating plate is arranged on the vertical side. A straight slot and a bolt which are in fit connection with each other are arranged on the bottom side and the limiting locating plate respectively, and are also arranged on the vertical side and the fastening locating plate respectively. The installation measurement tool disclosed by the invention is capable of accomplishing the installation and adjustment of an elevator landing door device conveniently, effectively and accurately, and ensures the consistence both in the spacing between elevator landing sill and car sill and in the horizontal spacing between landing sill and car sill.

Description

[0001] technical field [0002] The invention belongs to the field of installation and measurement tools, in particular to an installation and measurement tool for elevator floor door sills. Background technique [0003] The existing traditional way of installing the elevator landing sill is to use a tape measure to ensure the distance between the elevator landing door sill and the car sill. According to EN81 or the national standard, the error between the sills should be less than 3mm, which is very important for the installation workers. Generally speaking, it is difficult to keep the horizontal position between the sills of each floor unchanged and the maximum error is less than 3mm. The distance between the elevator floor door sill and the car sill shall not be greater than 35mm according to the requirements of the national standard and EN81. The error precision is 0~+3. The existing installation method uses guide rails and sills to use their own reference lines, and t...
