Description

Technical Field

[0001] This utility model belongs to the field of construction surveying technology, and in particular provides an adjustable tray for the bottom of a tripod of a surveying instrument. Background Technology

[0002] During engineering construction surveying, the tripod for surveying instruments is usually placed directly on the ground or structure, and then the tripod under the surveying instrument is leveled. The main drawback of this method is that when the ground or structure is uneven, the tripod is prone to instability during the adjustment process, which can cause the surveying instrument to fall and be damaged. Utility Model Content

[0003] The purpose of this utility model is to provide a bottom adjustment tray for a measuring instrument tripod, which solves the problem of tripod instability caused by uneven ground or structures.

[0004] This invention involves first placing the adjustment tray on the ground or a structure, then fixing the measuring instrument on the tripod, placing the tripod on the tray and stabilizing it, then turning the lever up and down until the tray is basically level, and then fine-tuning the tripod to make the measuring instrument level, before using the measuring instrument for measurement work.

[0005] This utility model includes a base 1, bolts 2, lower nuts 3, upper nuts 4, handles 5, connecting rods 6, and a support plate 7, which are used in combination. The four upper nuts 4 and four lower nuts 3 are welded to the two ends of the same side of the four connecting rods 6 respectively; the four bolts 2 are screwed into the four upper nuts 4 and four lower nuts 3 respectively; four handles 5 are welded to the upper ends of the four bolts 2 respectively; the lower ends of the four bolts 2 are welded perpendicularly to the four bases 1 respectively; the four corners of the support plate 7 are welded perpendicularly to the lower ends of the four connecting rods 6 in the horizontal direction (see...). Figure 1 , Figure 2 ).

[0006] The base 1 is made of 20mm thick steel plate and has a length of [missing information]. Width is 100 100mm; Bolt 2: 20mm diameter, 300mm long; Lower nut 3: 20mm diameter; Upper nut 4: 20mm diameter; Handle 5: 100mm long, machined from 10mm diameter round steel; Connecting rod 6: [unclear text - likely referring to a cross-sectional dimension] Width is 40 It is made of 40mm square steel and is 120mm long; the pallet 7 is made of 20mm thick steel plate and is 120mm long. Width is 600 600mm.

[0007] When using the instrument, first place the adjustment tray on the ground or a structure, then fix the measuring instrument on the tripod 8, then place the tripod 8 on the support plate 7 of the adjustment tray and hold it steady. Then, operate the handle 5 and turn the bolt 2 up and down until the support plate 7 is basically horizontal. Then, make fine adjustments to the tripod 8 to make the measuring instrument reach a horizontal position, and then use the measuring instrument to perform the measurement work. Figure 3 , Figure 4 ).

[0008] The advantages of this utility model are that it is easy to assemble, easy to operate, simple and practical, and avoids damage to measuring instruments caused by tripod instability due to uneven ground or structures. It is convenient and quick, and reduces construction costs. Attached Figure Description

[0014] Figures 1-4 This is one specific embodiment of the present invention. The present invention will be further described below with reference to the accompanying drawings.

[0015] This utility model includes a base 1, bolts 2, lower nuts 3, upper nuts 4, handles 5, connecting rods 6, and a support plate 7, which are used in combination. The four upper nuts 4 and the four lower nuts 3 are respectively welded to the two ends of the same side of the four connecting rods 6; the four bolts 2 are respectively screwed into the four upper nuts 4 and the four lower nuts 3; the four handles 5 are respectively welded to the upper ends of the four bolts 2; the lower ends of the four bolts 2 are respectively welded perpendicularly to the four bases 1; the four corners of the support plate 7 are respectively welded perpendicularly to the lower ends of the four connecting rods 6 in the horizontal direction.

[0016] When using it, first place the adjustment tray on the ground or a structure, then fix the measuring instrument on the tripod 8, then place the tripod 8 on the support plate 7 of the adjustment tray and hold it steady. Then operate the handle 5 to turn the bolt 2 up and down until the support plate 7 is basically horizontal. Then make fine adjustments to the tripod 8 to make the measuring instrument reach the horizontal position, and then use the measuring instrument to carry out the measurement work.

[0017] In engineering surveying and construction, a bottom adjustment tray was used to adjust the measuring tripod, achieving good results. This adjustment tray is used in combination. Four upper nuts and four lower nuts are welded to the two ends of the four connecting rods on the same side; four bolts are screwed into the four upper nuts and four lower nuts respectively; four handles are welded to the upper ends of the four bolts; the lower ends of the four bolts are welded perpendicularly to the four bases; and the four corners of the tray are welded perpendicularly to the lower ends of the four connecting rods in the horizontal direction. In use, the adjustment tray is first placed on the ground or structure, then the measuring instrument is fixed to the tripod. The tripod is then placed on the tray and stabilized. The bolts are then turned up and down using the handles until the tray is basically level. Fine-tuning of the tripod is then performed to ensure the measuring instrument is level before using it for measurement. This adjustment tray is simple to assemble, easy to operate, and practical. It avoids damage to the measuring instrument caused by tripod instability due to uneven ground or structures, offering convenience, speed, and reduced construction costs.
