Embodiment 1

[0032] Such as Figure 1~3 As shown, a device suitable for high-precision pre-embedding of vertical shaft strip keels includes a laser emitting device and a positioning device. Above; the positioning device includes a positioning platform 1, an adjustment device 14, and a base platform 2. The positioning platform 1 and the base platform 2 are two sets that are set up and down, the table is horizontal, the radius is the same, the central angle is a right angle, and they completely correspond to each other. Fan-shaped disc structure, the positioning platform 1 and the base platform 2 are connected by I-shaped steel 11, the positioning platform 1 and the base platform 2 have a card slot 21 at the position of the embedded part corresponding to the arc edge, and a light-transmitting positioning hole 61 at the central corner , the number and position of the slots of the positioning platform 1 are the same as those of the base platform 2, and the line connecting the center of the lig...

Embodiment 2

[0037] This embodiment is improved on the basis of Embodiment 1.

[0038] Two adjustment devices 14 are arranged on the positioning platform 1, and the two adjustment devices 14 are respectively arranged at both ends of the arc edge of the positioning platform. Two adjusting devices 14 are installed symmetrically at intervals of 90° on the arc edge of the positioning device. Two adjustment devices 14 are also arranged on the base platform 2 , and the positions of the adjustment devices 14 on the base platform 2 are the same as the number and position of the adjustment devices 14 on the positioning platform 1 .

Embodiment 3

[0040] A high-precision pre-embedded positioning method for a vertical shaft keel, using the device suitable for high-precision pre-embedding of a vertical shaft keel described in Embodiment 1 or 2, comprising the following steps:

[0041] In the first step, the positioning device is installed on site, and the laser emitting device is installed at the center of the bottom of the shaft;

[0042] The second step is to hoist the positioning device above the construction platform;

[0043] The third step is to use the bottom pulley 15 to move the positioning device according to the positioning point of the corresponding adjusting device on the shaft wall, and align the front end of the adjusting screw 42 of the adjusting device 14 to the positioning point;

[0044] The fourth step is to make the laser beam at the bottom of the shaft coincide with the center of the light-transmitting positioning hole 61 by adjusting the adjusting screw 42 of the adjusting device 14;

[0045] The fif...

Abstract

The invention discloses a device suitable for high-precision pre-embedding of strip-shaped keels in a vertical shaft and a positioning method. The device comprises a laser emitting device and a positioning device. The positioning device comprises a positioning platform, adjusting devices and a base platform; the positioning platform and the base platform are of two sector-disk-shaped structures which correspond mutually, the positioning platform and the base platform are connected through I-shaped steel, clamping grooves are formed in the positions, corresponding to pre-embedding pieces, of the circular arc edges of the positioning platform and the base platform, and light-transmitting positioning holes are formed in the central angle positions of the positioning platform and the base platform; the two or more adjusting devices are mounted on the inner side of the circular arc edge of the positioning platform for adjusting the distance between the positioning platform and the shaft wall, so that the centers of the light-transmitting positioning holes and the bottom center of the vertical shaft are subjected to laser overlapping, and the position of the positioning device is determined; and clamping devices are arranged in the middles of the inner sides of the clamping grooves to fix keel pre-embedding pieces. The keel pre-embedding pieces can be positioned precisely and rapidlyby the positioning device of the invention, and the positioning error of the positioning device is reduced through a laser positioning mode.

Description

technical field [0001] The invention relates to the technical field of installation of embedded parts, in particular to the technical field of high-precision installation of embedded parts of vertical shaft strip keel. Background technique [0002] Shaft embedded parts are pre-installed components in the shaft, which are used for lap joints when building the upper structure. Due to the large number of strip keel embedded parts in the vertical shaft and high precision requirements, ordinary construction methods not only consume a lot of time and labor costs, but also are difficult to meet the installation precision requirements. Contents of the invention [0003] The object of the present invention is to provide a device and positioning method suitable for high-precision pre-embedding of vertical shaft strip keels to solve the above problems. [0004] A device suitable for high-precision pre-embedding of vertical shaft strip keels, including a laser emitting device and a p...
