A device and method for quickly checking the verticality of a prism pole of a total station

Abstract

This invention discloses a rapid testing device and method for the verticality of a total station prism rod, comprising: a base, a support, and a fixing plate. The base is mounted on the top of the support, and has a slot at the top for mounting a laser. A point-of-view telescope for observing the laser beam spot projected onto the ground is mounted on the base. The fixing plate is connected to the base or support via connecting wires. The laser beam spot projected onto the ground is observed through the point-of-view telescope. The position of the fixing plate on the ground is adjusted to ensure that the laser beam spot falls completely within the center hole of the fixing plate. Then, the bottom tip of the total station prism rod to be tested is inserted into the center hole of the fixing plate. The circular bubble level on the total station prism rod is adjusted until the bubble is completely centered, ensuring the total station prism rod is vertical. The laser beam spot is observed through the laser point-of-view telescope to see if it coincides with the center of the crosshairs at the top of the prism rod. If they coincide completely, the verticality of the total station prism rod is qualified.

Description

Technical Field

[0001] The invention belongs to the technical field of engineering measurement and engineering monitoring, and in particular relates to a device and a method for quickly checking the verticality of a prism pole of a total station. Background Art

[0002] In the traditional field of engineering surveying and engineering monitoring, the total station is a measuring instrument that integrates optical, electrical and mechanical technologies. After the total station is installed, it can complete all measurement work including angle, distance, height difference, etc. at the station location. However, the verticality detection of the prism rod, which is its attached measuring tool, is very cumbersome. The current method is to use two total stations to inspect it. The two total stations are required to be at a right angle of 90° to the position of the prism rod, and the distance between the total station and the prism rod should be about 20 to 30 meters. Use the telescope of the total station to observe the prism rod, adjust the eyepiece crosshairs to a clear image, aim the objective lens at the installed prism rod, center the horizontal bubble of the prism rod, and make the vertical wire of the crosshairs in the total station eyepiece coincide with the tip of the prism rod. Then lock the left and right plates of the total station, and slowly move the total station telescope from bottom to top to the top of the prism rod to observe whether the crosshairs at the top of the prism rod and the crosshairs in the total station eyepiece completely coincide. If they coincide, the verticality of the prism rod is qualified, otherwise it needs to be adjusted. This method requires the coordination and inspection of two total stations, which is cumbersome to operate, time-consuming and costly. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a device and method for quickly checking the verticality of a prism pole of a total station. The device is simple to operate and has high accuracy, and can quickly check the verticality of a prism pole of a total station.

[0018] Step 3: Adjust the height adjustment screw under the base to make the base absolutely level;

[0019] Step 4: Turn on the laser, observe the laser beam spot directed to the ground through the telescope, loosen the connecting wire, adjust the placement of the fixing plate on the ground, ensure that the laser beam spot completely falls into the center hole of the fixing plate, and then hammer the fixing nail into the ground to ensure the stability of the fixing plate;

[0020] Step 5: Insert the bottom tip of the total station prism rod to be tested into the center hole of the fixing plate, and then adjust the circular level bubble on the total station prism rod until the bubble is completely in the middle position, so that the total station prism rod is in a vertical state, and observe through the laser pointing telescope whether the laser beam spot coincides with the center of the crosshairs at the top of the prism rod. If it completely coincides, it indicates that the verticality of the total station prism rod is qualified, otherwise the total station prism rod needs to be adjusted.

[0040] Embodiment 2

[0041] The method of using the device for quickly checking the verticality of the prism rod of the total station of the present invention is as follows:

[0042] Step 1: Before checking the verticality of the total station prism pole, install the laser in the laser bayonet 4 located at the top of the base 1, and tighten the first locking screw 3 to ensure the stability of the laser;

[0043] Step 2: Adjust the height of each leg of the bracket 8. When adjusting, ensure that the height is sufficient to place the total station prism rod at the bottom, and make the bubble of the circular level bubble 5 on the base 1 as centered as possible. After adjusting in place, tighten the second locking screw 9 of each leg to ensure the stability of the entire bracket;

[0044] Step 3: Adjust the height adjustment screw below the base so that the circular level bubble 5 on the base and the bubble in the level tube 6 are completely in the middle position to ensure that the entire base 1 is in an absolutely horizontal state;

[0045] Step 4: Turn on the laser, observe the laser beam spot directed to the ground through the telescope 2, loosen the connecting wire 10, adjust the placement of the fixing plate 11 on the ground, ensure that the laser beam spot completely falls into the center hole 12 of the fixing plate, and then hammer the fixing nail 13 into the ground to ensure the stability of the fixing plate.

[0046] Step 5: Insert the bottom tip of the total station prism rod to be tested into the center hole of the fixing plate, and then adjust the circular level bubble on the total station prism rod until the bubble is completely in the middle position, so that the total station prism rod is in a vertical state, and observe through the laser pointing telescope whether the laser beam spot coincides with the center of the crosshairs at the top of the prism rod. If it completely coincides, it indicates that the verticality of the total station prism rod is qualified, otherwise the total station prism rod needs to be adjusted.

[0047] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0048] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0049] The present invention is described above by way of example. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by those skilled in the art without inventive effort falls within the protection scope of the present invention.
