Abstract

The invention discloses a gradienter for constructional engineering measurement. The gradienter comprises a base, wherein a mounting frame is fixedly connected to the upper end face of the base, a base plate is mounted on the mounting frame, a mounting base is fixedly connected to the upper portion of the side, deviating from the mounting frame, of the base plate, a rack is assembled at the upperend of the base plate through a rotating shaft, and a gradienter body is mounted on the bottom plate. According to the gradienter for constructional engineering measurement, a positioning block is arranged to be matched with scale marks, so that a user can conveniently check whether the placement position of the gradienter deviates or not in time; moreover, the gradienter can deflect by rotating the worm until the gradienter and the center line of the scale line are positioned on the same vertical line, so that the measurement precision is ensured; the base plate can be driven to lift by rotating a hand wheel, so that the placement position of the gradienter is changed; in addition, a damping spring is arranged between an assembling base and the base, so that the gradienter is more stablewhen moving on an uneven road surface.

Example Embodiment

[0019] Example 1
[0020] see Figure 1-4 , a level used for construction engineering measurement, comprising a base 1, the upper end surface of the base 1 is fixedly connected with a mounting frame 5, a reinforcing rib is fixedly connected between the mounting frame 5 and the base 1, and the mounting frame 5 is movable The base plate 7 is installed, and the upper part of the side of the base plate 7 facing away from the mounting frame 5 is fixedly connected with the mounting base 11, and the lower end of the mounting base 11 is fixedly connected with the base plate 7. , the cross-section of the frame 13 is concave, and the frame 13 is rotated through the assembly shaft 23 to be equipped with a base plate 16, and a level 17 is installed on the base plate 16; one side of the base plate 16 is fixedly connected with an assembly rod 18, and the assembly rod 18 is connected via The wire rope 21 is connected with a positioning block 19; one side of the frame 13 and the base plate 16 is provided with a scale line 22 in a uniform arc-shaped area, and the positioning block 19 is suspended on one side of the scale line 22, so as to observe the device Whether it is placed horizontally; one end of the assembly shaft 23 extends to the inside of the frame 13 and is equipped with a worm wheel 24, and the inside of the frame 13 is equipped with a worm 25, the worm 25 is located below the worm wheel 24 and is in transmission connection with the worm wheel 24. One end extends to the outside of the frame 13 and is fixedly connected with a hexagonal head 15, so as to adjust the placement position of the level 17 and improve the measurement accuracy.
[0021] Further, the mounting frame 5 is equipped with a vertical lifting screw 14, and the mounting frame 5 is provided with two non-through chute 8 at intervals, and the two chutes 8 are symmetrically distributed on both sides of the lifting screw 14. , the base plate 7 and the lifting screw rod 14 are driven and installed and slidably installed with the chute 8; the upper end surface of the fixed base 6 is fixedly installed with a drive chamber 9, and a horizontal drive shaft 27 is installed in the drive chamber 9, and the drive shaft 27 is assembled Drive wheel 28 is arranged, and one end of drive shaft 27 extends to the outside of drive cavity 9 and is fixedly connected with handwheel 10, and one end of lifting screw 14 extends to the inside of drive cavity 9 and is equipped with interlocking wheel 26, and interlocking wheel 26 and driving The wheels 28 are driven and engaged to drive the base plate 7 up and down.
[0022] Further, one end of the rotating shaft 12 extends to the inside of the mounting base 11 and is connected with a rotary motor for transmission to adjust the measurement angle of the level 17 .
[0023] Further, the lower end of the base 1 is evenly equipped with a plurality of universal wheels 2, and a locking switch is arranged on the universal wheels 2, and a push rod 3 is fixedly connected to one side of the upper end surface of the base 1.
