Description

Hand-free fast leveling device for leveling ruler

technical field

The utility model relates to a hand-free fast leveling device for a leveling rod, which relates to a device capable of quickly leveling the leveling rod without hands, and belongs to the field of surveying and mapping equipment. In particular, it relates to a device capable of quickly leveling a leveling rod during leveling measurement without support.

Background technique

At present, the use of leveling rods is very common in leveling surveys, especially when conducting large-scale leveling surveys, a large number of stations need to be set up, and each station needs to read the front sight and the back sight twice. , it is necessary to manually support the ruler. First place the bottom center of the leveling ruler on the leveling origin, hold the leveling ruler with both hands to prevent it from shaking, and then wait for the reading staff to read. This will not only delay more time, but also must Two people are needed to complete the work of leveling, and the staff who hold the ruler must concentrate on holding the ruler to ensure the accuracy of the reading, otherwise, if the inspection fails, the reading must be repeated. On the other hand, when a person is holding the ruler, the hand will shake slightly, which will cause the ruler to shake back and forth, resulting in errors in readings. We usually use the "double-sided ruler method" when measuring ruler reading. If the conventional manual ruler method is used, this will cause another error. After reading the reading on one side of the ruler, it is necessary to read the other side of the ruler. Rotating the ruler by hand and verticalizing the ruler again will cause the ruler to vertically reach a new position due to the inaccuracy of human positioning, and such readings will produce errors again. This kind of accidental error will accumulate step by step. In the end, the reading may exceed the limit when processing the data. Once the reading exceeds the limit, it has to be re-measured. If it is not re-measured, the quality of the measurement will be affected, and re-measurement will delay manpower physical resources.

In order to improve the above situation, the utility model provides a hand-free fast leveling device for a leveling rod, which provides a device that can quickly level the leveling rod and does not need to be supported during leveling measurement. It can effectively improve the efficiency of leveling measurement, save manpower, and it is also easy to learn and operate for leveling personnel.

A hand-free fast leveling device for a leveling ruler of the utility model is realized in the following way: a hand-holding fast leveling device for a leveling ruler of the utility model is composed of a main body bracket and a gravity body part. The main body bracket is composed of a support rod, an adjustment knob, a main V-shaped connecting pipe, an auxiliary V-shaped connecting pipe, a fixed shaft, a square sleeve, a fixed knob and a level bubble. One end of the two support rods is respectively sleeved on both ends of the main V-shaped connecting pipe through the adjusting knob, the apex of the main V-shaped connecting pipe is placed on the side of the square sleeve through the fixed shaft, and one end of the two supporting rods is respectively sleeved through the adjusting knob. Connected to both ends of the auxiliary V-shaped connecting pipe, the apex of the auxiliary V-shaped connecting pipe is placed on one side of the square sleeve through the fixed shaft, and the level bubble is placed on the square sleeve. The gravity body part is made up of limit rod, fixing knob, sleeve, gravity body, limit shaft, connecting rod, connecting knob and limit groove. The limit groove is placed on the limit rod, the gravity body is placed on the bottom of the sleeve, one end of the connecting rod is placed on the sleeve through the limit shaft, and the other end is placed in the limit groove on the limit rod through the connection knob, and the limit The other end of the position rod is placed at the junction of the main V-shaped connecting pipe and the square sleeve through the fixed shaft.

During use, at first the adjustment knob and the connection knob are loosened, so that the support rod is separated from the main V-shaped connecting pipe and the auxiliary V-shaped connecting pipe, and the limit rod and the connecting rod are separated. Then make the device stand directly above the horizontal origin, and then fix the adjustment knob so that the device stands firmly on the ground. According to the left and right movement of the level bubble, adjust the adjustment knob to adjust the height of the support rods at both ends of the main V-shaped connecting pipe and the height of the supporting rods at both ends of the auxiliary V-shaped connecting pipe, so that the square sleeve is horizontal, and then the leveling rod is vertically adjusted. Insert the sleeve straight into the square sleeve, and at the same time put the sleeve on the bottom of the leveling rod. The leveling rod swings by gravity. When it stops, it can be in a horizontal state, and then the sleeve can be passed through by adjusting the connection knob The limit rod and the connecting rod are fixed to prevent the level rod from shaking. That is, the leveling rod can be vertical without holding it by hand. The purpose of quickly leveling the leveling rod without support is achieved during leveling measurement.

Beneficial effect.

1. The structure is simple, convenient and practical.

Second, the cost is low and easy to promote.

3. It can effectively improve the efficiency of leveling measurement and save manpower.
