Description

[0001] The present invention relates to the field of geodetic metrology, in particular to laser devices for generating reference axes intended for carrying out marking work in construction, in the assembly of technical equipment in mechanical engineering, as well as in other fields of science and technology where a light surface and the possibility of transferring markings in horizontal and vertical planes are required.

[0002] Line lasers are known, with laser beam sources, prisms for converting the laser beams into a surface and a self-leveling pendulum compensator, which enables the creation of a horizontal and a vertical laser reference plane.

[0003] However, the well-known line laser only allows the projection of a vertical and a horizontal plane and therefore cannot be used for work involving transferring markings between walls.

[0004] The line laser chosen as a prototype is closest to the claimed line laser in terms of technical design and achievable effect. It comprises a self-levelling platform with laser beam sources mounted on it, prisms for converting the laser beams into a plane, a power supply and control system, and a mounting unit, all housed in a common housing.

[0005] A disadvantage of the known device is that all complex and expensive components of the line laser are rigidly connected and installed in a single housing, with no possibility of division into functionally complementary modules, making it impossible to configure the device depending on the tasks to be solved. Furthermore, the known line laser is structurally complex, which leads to increased production costs, and is also large and heavy.

[0006] The object of the present invention is to create a multifunctional, user-friendly device consisting of modules whose configuration and assembly is possible without special effort and cost depending on the intended use of the line laser, which improves the usage properties.

[0007] In addition, the object solved by the present invention is to expand the spectrum of technical means that enable the creation of several levels and their relative arrangement.

[0008] The technical result that solves this problem is the division of the device into a radiation module and a mounting module, which are designed in such a way that they can be connected to each other as well as to several radiation modules, the number of which is determined by the tasks to be solved.

[0009] The solution according to the invention is achieved in that, in the line laser, which includes a self-leveling platform with installed laser beam sources, lenses for converting the laser beams, a power supply and control unit, and a mounting unit for a tripod, the laser sources, which perform the function of projecting reference axes, are separated into a radiation module equipped with a housing that additionally houses the power supply and control units. The self-leveling platform, power supply and control unit, and the mounting unit for the tripod are separated into a mounting module, which is also equipped with a housing. The housing of the radiation module and the housing of the mounting module are designed to be interconnected.

[0010] The lenses for converting the laser beams can be designed to split the beams into a surface.

[0011] The lenses for converting the laser beams can be designed as rotating prisms.

[0012] The lenses for converting the laser beams can be designed as diffractive optical elements (DOEs).

[0013] The lenses for converting the laser beams can be designed to split the beams into plumb points.

[0014] The mounting module can be designed so that radiation modules with different combinations of lenses for converting the laser beams can be mounted simultaneously.

[0015] The mounting module can be designed without a power supply and control unit, with the self-leveling platform being equipped with spirit levels and adjustment screws.

[0016] The proposed line laser can be manufactured in any specialized manufacturing facility, as it uses well-known materials and standard equipment that are widely used both domestically and internationally.

[0017] Therefore, the claimed line laser also meets the criterion of “industrial applicability”.

[0018] The separation of the laser sources, which perform the function of projecting reference axes, into a radiation module with an integrated housing, power supply and control system allows the creation of a module that can be used both as a standalone device and as an additional device for the tasks for which the line laser is intended, thus improving its usability and expanding its functionality.

[0019] The separation of the self-leveling platform, the power supply and control unit, and the tripod mount into a mounting module with a housing also enables a module that can be used both independently and as an additional device when tasks are expanded, which improves the usability of the line laser and extends its functionality.

[0020] The design of the housings of the radiation and mounting modules with the possibility of connection allows for simple and cost-effective configuration of the device for specific tasks, thereby increasing the performance characteristics and varying the dimensions, weight and production costs.

[0021] The design of the lenses for converting laser beams with the possibility of converting them into a surface improves the usability and expands the possibilities for placing reference axes.

[0022] The design of the lenses as rotating prisms increases the range of the projection axes.

[0023] The design of the lenses as diffractive optical elements (DOE) increases the number of reference axes without repositioning the line laser.

[0024] The design of the lenses for converting the laser beams with the possibility of projection into plumb points allows the transfer of markings from the floor to the ceiling.

[0025] The design of the mounting module with simultaneous installation of various radiation modules with different combinations of conversion lenses opens up possibilities for configuring a hybrid line laser with extended functions.

[0026] The design of the mounting module without power supply and control and the equipment of the self-leveling platform with spirit levels and adjustment screws enable a significant reduction in manufacturing costs.

[0027] Thus, the totality of the essential features of the proposed line laser allows achieving the specified technical result, namely the separation of the line laser into radiation and mounting modules, which can be connected both to each other and to additional radiation modules, the number of which is determined by the specific task, and thus the solution of the set task - improvement of the performance characteristics.
