Embodiment Construction

[0013] from Figure 1 to Figure 3 It can be seen that in the present invention, the telescopic support leg 1, the counterweight cylinder 2, the counterweight body 3, the connecting frame 4, the instrument connecting bolt 5, the annular threaded disc 6, the support bearing 7, the block 8, the instrument horizontal tray 9, the short The positional relationship of each parts such as connecting rod 10, long connecting rod 11 and handle 12. Figure 4 The structure of the annular threaded disc 6 is schematically shown.

[0014] Below in conjunction with accompanying drawing, the implementation process of the present invention will be further described:

[0015] Pull out the tripod support legs 1 to a suitable length and open them before the measurement, support the tripod on the ground and fasten the legs. At this time, the instrument tray 9 may not be in the horizontal plane. Screw the counterweight cylinder 2 into the draw-in groove of the connecting frame 4, move the handle 12 ...

Abstract

The invention provides an automatic leveling tripod. The automatic leveling tripod consists of retractable outriggers, a balance weight cylinder, balance weight bodies, a connecting frame, an instrument connecting bolt, an annular thread disc, a bearing, a fixture block, an instrument level tray, a short connecting rod and a handle. When the automatic leveling tripod is put up, the handle is pulled clockwise to loosen the fixture block; because the balance weight bodies are uniformly distributed in the balance weight cylinder and integrated with the connecting frame having a spherical structure to form an axisymmetric piece, and the centre of gravity is lower than that of the supporting bearing, the upper surface of the instrument tray is automatically leveled under the action of gravity; the handle is pulled anticlockwise to make the fixture block advance inward under the action of the annular screw disc, so that the instrument tray is locked; and the instrument can perform measurement by fine tuning after being arranged. The automatic leveling tripod has the advantages of improving working efficiency and reducing operational difficulty for staff.

Description

technical field [0001] The invention relates to a tripod used in the surveying industry, in particular to a tripod capable of automatic adjustment. Background technique [0002] In the measurement industry, a tripod is often used as a support for a theodolite or a level. Before measurement, it is necessary to repeatedly adjust the length and position of the outriggers to roughly adjust the level of the instrument installation tray, which is very troublesome. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention provides a tripod that can be automatically leveled and has the characteristics of easy operation. [0004] The invention is composed of telescopic outriggers, counterweight cylinder, counterweight body, connecting frame, instrument connecting bolts, annular threaded disk, support bearing, clamping block, instrument horizontal tray, short connecting rod, long connecting rod and handle; its features That is: the three...
