Description

Technical Field

[0001] The present invention belongs to the field of geometric measurement, and specifically relates to a stable support platform for high-altitude lifting, which is directly applied to related large-size precision measurement, especially in the field of aerospace precision measurement, and is equipped with laser trackers and other equipment to carry out related measurement work. Background Art

[0002] With the vigorous development of the country's aerospace industry, related scientific research and production tasks are also increasing. In the process of production, assembly and final assembly of aerospace product components, precision measurements are required many times. The precision measurement process usually uses laser trackers and theodolites as measuring instruments. By aiming at fixed target points on the object to be measured, the position relationship of each component of the object to be measured can be calibrated. The platform equipped with measuring instruments such as laser trackers needs to be portable, highly stable, arbitrarily adjustable in height, with a large adjustment range and easy to operate. Multiple factors play an important role in the accuracy of precision measurement results.

[0003] At present, the commonly used high-altitude measurement support platform is mainly realized in the following ways. One is to build a fixed metal base platform, install multiple sets of high-strength vertical support column components on the platform, configure multiple sets of tensioning steel ropes or pull rods for auxiliary support, and place the measuring instrument on the top of the equipment to realize the measurement process. At the same time, the number of support columns can be adjusted according to the requirements of the support height to achieve height adjustment. The disadvantage of this method is that each time the equipment under test at different heights needs to be reassembled and adjusted, the assembly process is relatively complicated, which affects the work efficiency, and the vertical direction cannot be accurately positioned. The second is to carry an integral column-type measuring platform, the bottom of which is equipped with a heavy rectangular or triangular support seat to support the marble or metal vertical column. Through the auxiliary support of each independent unidirectional pull rod, the measuring instrument is moved vertically along the column in the form of a screw drive to realize the measurement process of each height. The disadvantage of this method is that the overall load of the column is heavy, so it is inconvenient to move, and it is not suitable for continuous and efficient measurement. At the same time, due to the use of a screw-guided structure and taking into account mobility, its overall height is limited, and it is difficult to achieve a high-altitude measurement process. The third is to use a heavy-duty precision measurement platform. This type of platform installs a multi-stage lifting device on a drivable mobile base, and carries a measuring instrument to adjust the height and position. The disadvantages of this platform are that it occupies a relatively large space, is expensive, and cannot guarantee the accuracy of the platform's lifting, and still cannot achieve continuous automated measurement. In order to meet the actual needs of related measurements, the lifting support platform must not only achieve a large range of vertical movement of the measuring instrument and ensure stable support, but also be portable and mobile to achieve efficient measurement. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] One embodiment of the present invention provides a stable support platform for high altitude lifting, such as Figure 1 As shown, the stable support platform for high-altitude lifting of an embodiment of the present invention is used for high-altitude lifting of measuring instruments 3 such as laser trackers and theodolites to achieve high-precision measurement, and includes a simple displacement platform 4, a Z-axis lifting guide rail 1 and a triangular support member 2.

[0026] The simple displacement platform 4 is installed below the Z-direction lifting guide rail 1 as the main supporting motion platform of the overall structure. The top surface is fixed to the bottom of the Z-direction lifting guide rail 1 and the triangular support member 2 respectively, serving as the stable bottom foundation of the two, while taking into account the functions of driving the overall structure to move and providing stable support. The Z-direction lifting guide rail 1 is installed above the simple displacement platform 4, and is connected and fixed to the simple displacement platform 4 through the triangular support member 2, on which a measuring instrument 3 is installed, which can be driven by the control console 5 to move up and down along the guide rail 26. The triangular support member 2 serves as a fixed tensioning member between the Z-direction lifting guide rail 1 and the simple displacement platform 4, and ensures the stability and reliability of the overall support structure by applying a certain uniform tension to the triangular stable structure.

[0027] like Figure 2As shown, the simplified displacement platform 4 includes a control console 5, an active driving wheel 6, a driven wheel 7, a V-shaped platform base 8, a support adjustment wheel 9 and a support base 10. The V-shaped platform base 8 is welded with a steel metal structure, and is configured with sufficient weight to ensure that the center of gravity of the entire device is at a low level, ensuring safe and reliable operation. At the same time, the overall outer contour is a nearly V-shaped structure, which can not only ensure sufficient support area, but also effectively meet the motion layout of the single drive structure. The bottom end side of the V-shaped platform base 8 is installed with an active driving wheel 6 with an omnidirectional drive function, which can be turned and moved under the control of the control console 5, and independently drive the entire structure to achieve displacement in all directions. Four driven wheels 7 are installed on both sides of the bottom of the V-shaped platform base 8, which can achieve follow-up displacement while ensuring effective support for the entire structure, meeting the functional requirements of stable movement. Support adjustment wheels 9 are installed at the three corners of the V-shaped platform base 8, and by adjusting the support adjustment wheels 9, three-point stable support can be achieved for the V-shaped platform base 8 in the measurement state. A support base 10 with a universal ball head structure is installed at the bottom of each support adjustment wheel 9, which is used to directly contact the ground support to ensure stable support. A control console 5 is installed above the middle end of the V-shaped platform base 8 to realize the manipulation and control of the overall lifting and displacement to meet the electrical control needs of the equipment operation.

[0028] like Figure 3As shown, the Z-direction lifting guide rail 1 includes a top sprocket 16, a magnetic guide rail 17, a transmission chain 18, an electromagnet 19, a bottom driving wheel 20, a fixed support wing 21, a movable bottom plate 22, a pull rod 23, a slide plate 24, a matching platform 25, a guide rail 26 and a column 27. The column 27 is the main component of the Z-direction lifting guide rail 1 and is made of an aluminum welded structure. The internal hollow structure ensures stability to the greatest extent while reducing weight. The bottom is equipped with a fixed support wing 21 to ensure the support strength and stability of the column 27. Two sets of equidistant and parallel guide rails 26 for guiding are respectively installed on the front and back sides of the column 27. The slide plate 24 that can move up and down along the Z direction is installed on the front guide rail 26 of the column 27. The movable bottom plate 22 is installed above the slide plate 24, and the two are fixed by a pull rod 23. The movable bottom plate 22 is arranged with a universal interface for installing measuring instruments. The magnetic guide rail 17 is installed in the middle of the front of the column 27 as a safe holding structure for the operation of the slide plate 24. The electromagnet 19 is installed inside the slide plate 24 and is magnetically connected to the magnetic guide rail 17. The magnetic guide rail 17 can be released under the control of the control console 5, so that the slide plate 24 can move freely along the guide rail 26. In non-operating conditions such as power-off conditions, it is in a normally open state and magnetically connected to the magnetic guide rail 17. When in operation, it is closed to realize the operating function. The bottom drive wheel 20 is installed at the bottom of the column 27, which can drive the upper transmission chain 18 to move up and down. The top sprocket 16 is installed at the top of the column 27 and can serve as an auxiliary transmission wheel at the other end of the transmission chain 18. The transmission chain 18 is fixed at both ends of the slide plate 24, which can drive the slide plate 24 to move up and down along the Z direction, thereby realizing the lifting and lowering of the measuring instrument 3. At the same time, with the built-in grating ruler, the precise positioning of the slide plate 24 can be achieved. In order to achieve stable constant load operation, the balance platform 25 is installed on the guide rail 26 on the back of the column 27 and fixed to the other two ends of the transmission chain 18 to balance the weight of the slide plate 24 and the measuring instrument 3 to optimize the stability of the overall operation.

[0029] like Figure 4As shown, the triangular support member 2 includes an upper fixing seat 11, an upper rod group 12, a lower fixing seat 13, a lower rod group 14 and a bottom fixing seat 15. The bottom fixing seat 15 is installed on the top surface of the V-shaped platform base 8, and the bottom fixing seat 15 is respectively connected to the upper rod group 12 and the lower rod group 14. The rod groups are arranged symmetrically on four sides and are respectively installed in four symmetrical directions. The lower fixing seat 13 is installed in the middle of the side of the column 27 to connect and fix the lower rod group 14, and the upper fixing seat 11 is installed on the top of the side of the column 27 to connect and fix the upper rod group 12. The whole is installed in a plurality of triangular stable structures. The adjacent lower rod groups 14 and the V-shaped platform base 8, the adjacent upper rod groups 12 and the V-shaped platform base 8, the upper rod group 12 and the lower rod group 14 and the column 27 are all arranged in a triangular structure to ensure the stability of the overall structure of the column to the greatest extent. The overall structure is in a pre-tensioned form. Sufficient pre-tightening tension is generated by bolting and fixing the bottom fixing seat 15 and the V-shaped platform base 8 to ensure the synchronization of four-way tensioning. The pre-tightening force is adjusted by a torque wrench to ensure that the pre-tightening force in the four directions is consistent.

After reaching the measuring position, the electromagnet 19 is controlled to hold the magnetic guide rail 17 tightly. After stabilization, the measuring instrument 3 with height position is manually or automatically controlled by a program to measure at different heights and record the measurement results. By continuously adjusting the position of the support platform and the measuring height, efficient measurement of the object 29 can be achieved.
