Description

Technical Field

[0001] The utility model belongs to the technical field of measuring equipment, and in particular relates to a detachable installation structure for a measuring instrument. Background Art

[0002] At present, in the process of excavating the foundation pit of the shield starting section, some projects mainly control the excavation edge line of the foundation pit during the excavation process, because the excavation edge line of the foundation pit is the inner contour line of the maintenance structure of the working pit. At the same time, the completed excavation surface is regularly inspected. The continuous wall that invades the structure must be removed in time to ensure the thickness of the working pit structure. The measurement team must check the excavation depth every day. In this work, as the excavation depth of the foundation pit increases, the instrument set up next to the foundation pit can no longer meet the measurement needs due to the gradual increase in the pitch angle. Figure 4 As shown, the instrument is set up at measuring point A. The relevant measurements at the same height of point A in the foundation pit can be measured, but the points below point A cannot be observed due to the obstruction of the retaining wall and the pitch angle of the instrument (points B and C). In addition, the height of the retaining wall of the foundation pit is generally 1.5m or above, and the height of the instrument sometimes needs to reach about 1.8m to 2m. The surveyor needs to step on the relevant pads to perform the observation. For measuring point C, it is generally necessary to set up the instrument in the foundation pit. The extreme pitch angle can only be observed at the height of point C. At this time, the observer is already in a kneeling position. When the construction conditions in the foundation pit do not meet the requirements for setting up the instrument, it is often necessary to use the hanging steel ruler method on the crown beam to perform reverse measurement. This method is relatively cumbersome and has safety hazards.

[0003] In other surveying work, we often encounter situations where the surveying work cannot be carried out due to wall obstruction. For example, in the cadastral surveying of rural real estate homesteads, it is often encountered that there is no one at home or there is a dog in the yard and the surveyors cannot enter. The tripod-mounted instruments outside the yard are often unable to carry out related surveying operations due to the wall blocking the view. Figure 5 shown.

[0004] Therefore, it is urgent to develop a tester installation structure that can solve the problem of wall blocking the instrument's visibility during measurement work. Utility Model Content

[0005] The utility model aims to provide a detachable installation structure for a measuring instrument, so as to solve the problem that the existing tripod is blocked by a wall during the measuring work and the instrument visibility is blocked.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a detachable installation structure for a measuring instrument, comprising a tray and two groups of connecting components located on both sides of the tray, and the measuring instrument is installed on the tray; each group of the connecting components comprises a connecting plate and a clamping plate, and the connecting plate and the tray are detachably connected by a first connecting piece; the connecting plate and the clamping plate are detachably connected by a second connecting piece, and the angle between the connecting plate and the clamping plate can be adjusted and fixed by the second connecting piece; when the two groups of the clamping plates are clamped, they are respectively located on both sides of the wall; each group of the clamping plates is provided with a clamping piece, and the clamping piece can move laterally on the clamping plate, and the clamping pieces on both sides of the wall can clamp the wall.

[0007] Furthermore, a first connecting block is provided on both sides of the tray, a second connecting block is provided on a side of the connecting plate close to the tray, and the first connecting block and the second connecting block are overlapped; a first strip hole is provided on the first connecting block, and a second strip hole is provided on the second connecting block that can be opposite to the first strip hole, and the length directions of the first strip hole and the second strip hole are respectively consistent with the length directions of the first connecting block and the second connecting block; the first connecting member connects the first connecting block and the second connecting block through the first strip hole and the second strip hole.

[0008] Furthermore, a first protrusion is provided on one side of the connecting plate close to the clamping plate, and a second protrusion is provided on one side of the clamping plate close to the connecting plate; a first threaded hole is provided on the first protrusion, and a second threaded hole opposite to the first threaded hole is provided on the second protrusion; the second connecting member adopts a threaded member, and the second connecting member can be threadedly connected with the first threaded hole and the second threaded hole.

[0009] Furthermore, the clamping plate is provided with a plurality of third threaded holes, the clamping member is a threaded member, and the clamping member is threadedly connected to the third threaded holes.

[0010] Furthermore, a centering threaded member is provided on the tray, and a fourth threaded hole is provided at the bottom of the measuring instrument, and the centering threaded member can be threadedly connected to the fourth threaded hole.

[0011] The working principle of this technical solution is that this device is used when the wall is blocked and the tripod is used to install the measuring instrument, which will block the instrument's line of sight. This device is used to install the measuring instrument on the wall. The specific installation method is as follows: first assemble the tray and the connecting plate, roughly adjust the overlapping range of the two according to the width of the wall, and make the first strip hole and the second strip hole face each other, and then use the first connecting piece to fix the tray to the connecting plates on both sides. Then place the assembled device above the wall. Then adjust the angle between the clamping plate and the connecting plate (generally 90 degrees), and make the first threaded hole and the second threaded hole face each other. Then use the second connecting piece to connect and fix the clamping plate and the connecting plate, and the angle between the clamping plate and the connecting plate is also fixed at this time. Finally, by rotating the clamping piece, the clamping piece moves toward the wall until the clamping pieces on both sides press the two sides of the wall tightly. Finally, connect the measuring instrument to the centering screws on the tray to achieve the installation and fixation of the measuring instrument.

[0012] The beneficial effects of this technical solution are: ① This technical solution can not only realize the detachability of the measuring instrument, but also realize the detachability between the various components, which is convenient for assembly and carrying, and the storage after disassembly can reduce the occupied space. The measuring instrument can be directly installed on the wall using this installation structure to solve the problem that the wall blocks the line of sight of the instrument during the measurement work. ② In this technical solution, the overlapping part between the connecting plate and the tray can be adjusted, and the clamping piece can also be moved horizontally, so as to adapt to walls of different thicknesses. ③ The angle between the connecting plate and the clamping plate can be adjusted, which can be adjusted according to the specific conditions of the wall.
