Description

Technical Field

[0001] The invention relates to the technical field of leveling auxiliary equipment, and in particular to a building settlement observation ruler. Background Art

[0002] Building settlement observation is generally implemented through leveling, which is also called geometric leveling. The instruments used are level and level rod. The principle is to use the horizontal line of sight (obtained by the level) to obtain the readings of the rod erected at two points, calculate the height difference between the building settlement observation point and the reference point, and then obtain the building settlement data.

[0003] Existing building settlement observation usually requires personnel to hold the level rod upright at the settlement observation point for measurement. When conducting settlement observation in a small space such as crowded or "back-to-back" buildings, the observer cannot hold the level rod upright due to the small space. When measuring on irregular surfaces, such as special-shaped buildings, short bridge pier bases and other irregular surfaces, it is also difficult to keep the level rod upright, so it is impossible to obtain accurate data.

[0004] Therefore, a settlement observation scale which is easy to install and adjust in a small space is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a building settlement observation ruler to solve the problem that the level ruler is difficult to place and adjust when leveling is performed in a narrow space or on an irregular surface.

[0007] As a further technical solution of the above solution, the first adjusting device is an electric push rod, the output end of the electric push rod is connected to an adapter plate, and the right end of the adapter plate is hinged to the mounting plate.

[0008] As a further technical solution of the above scheme, the first adjusting device includes a motor mounting plate, a motor, a gear and a rack; the motor mounting plate is horizontally arranged below the connecting plate; the motor is connected to the motor mounting plate, and the output shaft of the motor is connected to the gear, and the gear is meshed with the rack; the left end of the rack is movably connected to the long strip through hole of the vertical plate through a limiting rod, and the right end is hinged to the mounting plate.

DETAILED DESCRIPTION

[0017] The technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems solved, the technical features constituting the technical scheme and the technical effects brought about.

[0018] like Figure 1 and Figure 2 As shown, a building settlement observation scale comprises a bar code ruler 7, a mounting frame, a connecting plate 2, a mounting plate 3 and a first adjusting device; Bar code ruler 7, used for level reading; A mounting plate 3, used for connecting to a building, with an upper end hinged to the right end of the connecting plate 2 and a lower end hinged to the first adjusting device; Connecting plate 2, the left end of which is connected to the mounting frame; A first adjusting device, the left end of which is connected to the mounting frame and is located below the connecting plate 2; The mounting frame includes a vertical plate 11, an upper horizontal plate 12 and a lower horizontal plate 13; the upper portion of the right side of the vertical plate 11 is connected to the connecting plate 2, and the lower portion is connected to the first adjusting device; the left side of the vertical plate 11 is respectively connected to the upper horizontal plate 12 and the lower horizontal plate 13; The lower surface of the upper horizontal plate 12 is connected to the upper end of the bar code ruler 7 through a rotating shaft, and the upper surface of the lower horizontal plate 13 is connected to the lower end of the bar code ruler 7 through a rotating shaft; The first adjusting device is used to adjust the bar code ruler 7 vertically.

[0019] When conducting settlement observation in a narrow space or other irregular surfaces, first fix the mounting plate 3 to the building, then set the barcode ruler 7 in the mounting frame, connect the mounting plate 3 using the connecting plate 2 and the first adjusting device, and the operator can manually adjust the first adjusting device to drive the vertical plate 11 to achieve fine adjustment, so that the barcode ruler 7 is in a vertical state; according to the position of the level, adjust and rotate the barcode ruler 7 to face the level to complete the installation and adjustment operation.

[0020] like Figure 1As shown, as a preferred embodiment, the first adjustment device is an electric push rod 41, the output end of the electric push rod 41 is connected to an adapter plate 42, and the right end of the adapter plate 42 is hinged to the mounting plate 3. When the first adjustment device is used, the electric push rod 41 is started to push the vertical plate 11 to move rightward or leftward. Since the left end of the electric push rod 41 is connected to the vertical plate 11, the vertical plate 11 moves rightward or leftward following the adapter plate 42, thereby adjusting the angle of the barcode ruler 7, and then making the barcode ruler 7 vertical.

[0021] like Figure 2 As shown, as a preferred embodiment, the first adjusting device includes a motor mounting plate 43, a motor 44, a gear 45 and a rack 46; the motor mounting plate 43 is horizontally arranged below the connecting plate 2; the motor 44 is connected to the motor mounting plate 43, and the output shaft of the motor 44 is connected to the gear 45, and the gear 45 is meshed with the rack 46; the left end of the rack 46 is movably connected to the long strip through hole of the mounting vertical plate 11 through the limiting rod 5, and the right end is hinged to the mounting plate 3. When the first adjustment device is used, the motor 44 is started, and the rotation of the motor 44 drives the gear 45 to rotate. Since the gear 45 and the rack 46 are meshed, the rack 46 moves to the right or left with the rotation of the gear 45. Since the motor mounting plate 43 is connected to the vertical plate 11, the vertical plate 11 also moves to the right or left at this time, so that the angle of the vertical plate 11 is adjusted, and the bar code ruler 7 is made vertical. Due to the self-weight problem of the rack 46, in order to maintain the stability of the rack 46 during movement, the left end of the rack 46 is connected to the vertical plate 11, and the elongated through hole is provided to provide the limit rod 5 with space for left and right movement, and the limit rod 5 will not be separated from the elongated through hole, and the load-bearing and limiting functions are always maintained.

[0022] like Figure 3 and Figure 4As shown, as a preferred embodiment, it also includes a second adjusting device, which includes a universal coupling 61, a spring 62 and a bolt 63; a circular adjusting hole 14 is provided on the lower cross plate 13, and a connecting seat is provided at the upper end of the bar code ruler 7; a spring 62 is provided on the lower surface of the upper cross plate 12, and the spring 62 is connected to the connecting seat through the universal coupling 61; a bolt 63 is provided at the lower end of the bar code ruler 7, and after the bolt 63 passes through the circular adjusting hole 14, the leveling bubble on the bar code ruler 7 is adjusted and then the bolt 63 is fixed with a fixing nut 64. In this embodiment, after adjustment using the first leveling device, there may be a situation where the bar code ruler is not particularly vertical. At this time, the second leveling device is required for precise adjustment. At this time, the operator rotates the bolt 63 below the bar code ruler 7. Since the upper part of the bar code ruler 7 is connected to the upper horizontal plate 12 through the universal coupling 61 and the spring 62, it still has a certain amount of expansion and contraction in the vertical direction under the condition of rotation, and the spring 62 is in a stressed state, which is relatively stable and not easy to shake; the front part of the bar code ruler 7 is provided with a bar code for the level reading, and a circular leveler for adjusting the verticality of the ruler is set at the back. The leveling bubble in the circular leveler is observed. When the leveling bubble is in the center circle, it indicates that the bar code ruler 7 is in a vertical state. At this time, a fixing nut 64 is inserted from the bottom of the bolt 63 and tightened to complete the fixation, which further improves the accuracy of the device.

[0023] like Figure 3 As shown, as a preferred embodiment, it also includes a limit frame 65, which is arranged at the lower end of the upper horizontal plate 12, and the four sides of the limit frame 65 are respectively pressed against the four sides of the universal coupling 61 to limit the up and down movement of the universal coupling 61 and the spring 62. In this embodiment, after the limit frame 65 is set, the limit frame 65 presses against the universal coupling 61 from all sides to limit the universal coupling 61, so that the universal coupling 61 can only move up and down in the vertical direction under the drive of the spring 62, thereby improving the stability of the elastic connection.
