Embodiment Construction
[0021] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0022] The basic idea of the present invention is to realize long-distance guidance by using the straight-line propagation characteristic of laser light, and simultaneously realize center positioning in the direction of the transverse axis and the direction of the longitudinal axis.
[0023] Combine below Figure 2 to Figure 4 , the preferred embodiment of the present invention will be described in further detail. Taking the wind turbine hoisting or maintenance process as an example, this preferred embodiment provides a laser positioning device for wind turbine hoisting or maintenance, including at least two laser emitters 100 and positioning Block 200. Two laser emitters 100 are symmetricall...

The invention discloses a laser positioning device for lifting or maintenance of draught fan. The laser positioning device includes at least two laser transmitters and a positioning block; the laser transmitters uses the linear propagation principle of laser, can guide the movement of draught fan lifting equipment or transport vehicle from a long distance, so that the central line of the lifting equipment and the central line of the bottom draught fan tower coincide on the transverse direction within the error range; and the positioning block is used to coincide the central line of the draught fan lifting equipment and the central line of the tower in the longitudinal direction, so as to accurately complete the initial positioning of a hoop device and the draught fan tower, ensure the smooth clamp of the hoop device and the draught fan tower; and a climbing ring of a self-lifting climbing pole device and the center of tower are concentric, so as to realize smooth climb, accurately lift the draught fan equipment, and provide convenience to the operator. Further, the laser positioning device can be applied to between any dynamic symmetric substance and static symmetric substance and make the central lines of the two coincide in transverse and longitudinal directions, so as to effectively guide the motion of dynamic symmetric substance with respect to the static symmetric substance.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a laser positioning device. Background technique [0002] At present, the installation of large-scale wind power generation equipment is mostly completed by using large-scale truck cranes or crawler cranes. However, large cranes are bulky, have low driving flexibility, and require many auxiliary transport vehicles during the movement process, which makes the hoisting cost of large wind power generation equipment very high. Especially when large-scale wind power equipment needs to be installed in harsh environments with long distances and complex road conditions, such as mountains and deserts, large cranes may not be able to reach the destination smoothly. , It is not easy to lift the wind power generation equipment to an altitude of tens or even hundreds of meters. [0003] like figure 1 As shown, in the prior art, in order to solve the above-mentioned problems, a self-jac...
