Description

Technical Field

[0001] The utility model belongs to the field of measuring instruments, in particular to a rapid leveling device for a level. Background Art

[0002] As a reliable engineering surveying instrument, the level has been widely used in various construction projects and road and bridge construction fields. Therefore, the efficiency and measurement quality of the level have a relatively large impact on the progress of the construction project and the final quality of the project. Under the existing technical conditions, when using the level for on-site construction measurement, it is first necessary to place the tripod of the level according to the on-site terrain, and then manually adjust the horizontal posture of the level. When the construction site is in the wild, it is impossible to ensure that the tripod has a relatively horizontal setting posture. At this time, it is difficult for the existing fine-tuning water platform to make a large-scale horizontal adjustment. At the same time, the existing fine-tuning water platform can generally only be adjusted manually, which is time-consuming and labor-intensive, affecting the efficiency of on-site measurement construction.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] According to the embodiment of the utility model, Figures 1 to 4As shown, a quick leveling device for a level comprises a circular first base 1; three universal damping ball heads 11 are arranged on the upper surface of the first base 1; the three universal damping ball heads 11 are arranged in an equilateral triangle with the center of the circle on the upper surface of the first base 1 as the center; the three universal damping ball heads 11 are connected to the bottom ends of three electric push rods 12 one by one, and the rod heads of the three electric push rods 12 are hinged on the lower surface of the second base 23; the rod heads of the three electric push rods 12 are arranged in an equilateral triangle on the lower surface of the second base 23; three vertically arranged screw rods are arranged on the upper surface of the second base 23, and the three screw rods are arranged in an equilateral triangle; the three apex corners of the triangular third base 24 are respectively movable up and down and are correspondingly arranged on the three screw rods; the three screw rods are respectively provided with limit bolts 25 for limiting the position of the apex corners of the third base 24 on the corresponding screw rods; the control ends of the three electric push rods 12 are respectively connected to the direction switch 13, the second base 23 and the level provided on the third base 24.

[0028] In this embodiment, the universal damping ball head 11 may also be a universal damping ball head 11 with a locking function.

[0029] In an embodiment, Figures 1 to 4 As shown, the process of an operator using the quick leveling device of the level disclosed in the utility model is as follows: first, the operator sets the tripod on the ground in the field and tries to keep the tripod stable and horizontal. Due to the complex outdoor environment, generally after the tripod is kept stable, there will be a relatively large tilt angle. At this time, the device is installed on the tripod, and the direction switch 13 is used to control the extension and retraction of the rod heads of the three electric push rods 12, thereby controlling the posture adjustment of the second base 23, and by observing the spirit level set on the second base 23, the second base 23 can quickly reach a horizontal posture.

[0030] Furthermore, the level meter disposed on the third base 24 is observed, and the limit bolts 25 are rotated accordingly to move the top angle of the third base 24 on the corresponding screw rod, so that the third base 24 can be further fine-tuned to achieve a better horizontal posture.

[0031] In this embodiment, the entire level rapid leveling device uses three electric push rods 12 for the first stage rapid leveling, and then uses the limit bolts 25 for the second stage fine adjustment, which takes into account both the leveling speed and the leveling quality.

[0032] In this embodiment, since three electric push rods 12 are used to adjust the horizontal posture, it has the characteristics of fast adjustment speed and large adjustment range, and is particularly suitable for leveling the level in the field environment.

[0033] In this embodiment, the fine-tuning horizontal platform 2 is composed of a second base 23 and a third base 24. Its function is to perform a second fine-tuning after a quick horizontal adjustment using three electric push rods 12. Under existing technical conditions, the fine-tuning horizontal platform 2 is a common leveling device, but this common fine-tuning horizontal platform 2 generally uses manual operation, and has the problems of slow adjustment speed and small adjustment range.
