Description

Technical Field

[0001] The utility model relates to the technical field of heliostat prefabricated piles, in particular to an RTK measurement and fixing device for measuring heliostat prefabricated piles. Background Art

[0002] The prefabricated piles supporting the heliostat are 2.5 meters above the ground. After the construction is completed, the coordinates of the pile center need to be measured using an RTK surveying instrument to verify the pile position. In the existing technology, the main unit of the RTK surveying instrument is fixed on the central screw of the device, and the surveyor needs to use a ladder to stand at a high place and hold on by hand, which makes the measurement difficult and unsafe.

[0003] Therefore, there is an urgent need for a device for quickly and safely measuring the prefabricated piles of heliostats. Utility Model Content

[0004] The utility model aims to provide an RTK measurement fixture for measuring a heliostat prefabricated pile so as to quickly and safely measure the central coordinates of the heliostat prefabricated pile.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An RTK measurement fixture for measuring a heliostat prefabricated pile, comprising a fixed cover plate covered on the top of the heliostat prefabricated pile, a hand-held rod fixedly supporting the fixed cover plate, a level fixed on the hand-held rod, and an RTK measuring instrument host fixed on the center of the top surface of the fixed cover plate;

[0007] The hand-held rod is arranged outside the side of the fixed cover plate.

[0008] Furthermore, a screw rod for connecting to a host of the RTK measuring instrument is fixed on the axis of the fixed cover plate.

[0009] Furthermore, the length of the hand-held rod is 1-1.5m.

[0010] Furthermore, the fixed cover plate is provided with weight-reducing holes.

[0011] Furthermore, the fixed cover plate is made of stainless steel.

[0012] Furthermore, the level is a universal bubble level.

[0013] Furthermore, the top end of the hand-held rod and the fixed cover plate are connected by a fastener.

[0014] Furthermore, the fixed cover plate includes a circular bottom and a plurality of arc-shaped plates perpendicular to the circular bottom, and adjacent arc-shaped plates are arranged at intervals in the circumferential direction of the circular bottom.

[0015] In the above technical solution, the RTK measurement fixture of the utility model has the following beneficial effects:

[0016] Surveyors can fix the RTK measuring instrument host at the center of the fixed cover plate, stand on the ground and place the fixing device on the top of the precast pile with a handheld rod. The center of the fixed cover plate is the center of the precast pile, which has the advantage of accurate positioning. Surveyors can read the center coordinates of the precast pile while standing on the ground, which speeds up the measurement, reduces the measurement difficulty, and improves the measurement safety.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] It should be noted that the terms "above", "one end", "upper", etc. used in this article indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Similar expressions are only for the purpose of illustration, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention; in addition, the terms "one part", "two parts", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0025] like Figure 1-3As shown, an RTK measurement fixture for measuring a heliostat prefabricated pile comprises a fixed cover plate 1 covered on the top of the heliostat prefabricated pile, a hand-held rod 2 fixedly supporting the fixed cover plate 1, a level 3 fixed on the hand-held rod 2, and an RTK measuring instrument host 4 fixed on the center of the top surface of the fixed cover plate 1.

[0026] The fixed cover plate 1 is in the shape of a cover, and the center of the fixed cover plate 1, the RTK measuring instrument host 4 and the precast pile are coincident. The hand-held rod 2 is arranged on the outside of the side of the fixed cover plate 1, that is, the side of the fixed cover plate 1 located on the circumference of the precast pile, and the hand-held rod 2 plays the role of holding the fixed cover plate 1. Figure 2 As shown, the fixed cover plate 1 is covered on the prefabricated pile of the heliostat.

[0027] A screw rod 11 for connecting the RTK measuring instrument host 4 is fixed on the axis of the fixed cover plate 1. The RTK measuring instrument host 4 is connected to the screw rod 1 through threads.

[0028] The length of the hand-held rod 2 is 1-1.5 m. In this way, the length is not too high, which is conducive to grasping the position of the fixed cover plate 1, and not too short, because a short person will not be able to reach the top surface of the precast pile.

[0029] The fixed cover plate 1 is provided with weight-reducing holes 12 to reduce the weight of the fixed cover plate.

[0030] The fixed cover plate 1 is made of stainless steel.

[0031] The level 3 is a universal bubble level, which is arranged at the bottom of the hand-held rod 2 or near the bottom, so as to facilitate human eye observation. A horizontal protrusion can be fixed on the hand-held rod 2 to serve as the installation basis of the level.

[0032] The top of the hand-held rod 2 and the fixed cover plate 1 are connected by fasteners. The fasteners are preferably detachable bolts and nuts. The axial direction of the bolts is placed horizontally, and the side of the hand-held rod and the fixed cover plate 1 are penetrated and fastened together, which is convenient for disassembling and storing the RTK measurement fixture.

[0033] The fixed cover plate 1 includes a round bottom and a plurality of arc-shaped plates perpendicular to the round bottom, and the adjacent arc-shaped plates are arranged at intervals in the circumferential direction of the round bottom. The fixed cover plate 1 can be a bottle cap type, that is, there is no interval between adjacent arc-shaped plates. However, the interval arrangement of adjacent arc-shaped plates reduces the difficulty for operators to lift the fixed cover plate and cover the precast pile. In the circumferential direction of the fixed cover plate 1, the interval length between adjacent arc-shaped plates can be greater than the length of the arc-shaped plates. Figure 2 There are four curved plates shown.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
