Description

Technical Field

[0001] The utility model relates to the technical field of measuring equipment, in particular to a foundation pit self-inspection device capable of adapting to multiple angles. Background Art

[0002] Foundation pit refers to a deep and wide pit or hole dug on the ground for the construction of underground buildings or projects. Foundation pits are usually dug in urban construction and are used to build underground parking lots, underground shops, underground passages, underground stations, underground storage tanks, underground tunnels and other underground structures. They may also be used to build the foundation of high-rise buildings, such as deep foundation pit buildings or high-rise buildings. After the foundation pit is excavated, the bottom position of the foundation pit needs to be measured to ensure that the depth of the foundation pit meets the use requirements. However, the depth of the foundation pit is generally measured manually using a tape measure. Due to the large softness of the tape measure, it is easy to bend during measurement, affecting the accuracy of the measurement. In addition, when there is an inclined surface at the bottom of the foundation pit, it is difficult for the tape measure to measure the depth of the inclined surface, and the measurement adaptability is low.

[0003] Therefore, in order to solve the above problems, a foundation pit self-inspection device which can accurately measure and is adaptable to multiple angles for complex foundation pit terrain is developed. Utility Model Content

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the protection scope and application scope of the present invention are not limited.

[0020] A self-inspection device for foundation pits that can be adapted at multiple angles, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a base 1, a clamping rod 2, a first scale plate 3 and a second scale plate 4. The first scale plate 3 for measuring the depth of the foundation pit is connected to the upper middle side of the base 1. The clamping rod 2 for limiting and clamping the foundation pit mouth is slidably connected to the first scale plate 3. The left and right parts of the clamping rod 2 are provided with hollow grooves. The upper part of the first scale plate 3 is rotatably connected to the second scale plate 4 for extending the measuring length. The second scale plate 4 and the clamping rod 2 are slidably connected. It also includes an adaptation mechanism 5. The adaptation mechanism 5 includes a first fixed seat 51, a second fixed seat 52, a support seat 53 and a first torsion spring 54. The first fixed seat 51 is connected to the lower middle side of the base 1. The lower part of the first fixed seat 51 is rotatably connected with two second fixed seats 52. A first torsion spring 54 is connected between the rear second fixed seat 52 and the first fixed seat 51. A support seat 53 for assisting in adjusting the support surface is connected between the lower sides of the second fixed seats 52. A protective frame is connected between the upper middle side of the support seat 53 near the second fixed seat 52.

[0021] This device can be used when self-checking the depth in the foundation pit. It should be noted that first, the second scale plate 4 is rotated upward to open, and the base 1 is placed at the foundation pit mouth, so that the clamping rod 2 is clamped with the foundation pit mouth, and then the second scale plate 4 is slid downward, so that the second scale plate 4 drives the first scale plate 3 to slide down into the foundation pit along the clamping rod 2, so that the support seat 53 contacts the bottom of the foundation pit, and then the depth of the foundation pit is observed through the contact position of the clamping rod 2 with the first scale plate 3 or the second scale plate 4. When the test position at the bottom of the foundation pit appears at an inclined position of different angles, press downward The second scale plate 4 is moved, so that the first scale plate 3 drives the base 1 to apply pressure downward, and then the support seat 53 is rotated to fit the inclined surface. At this time, the first torsion spring 54 is rotated under the force, and then the depth of the foundation pit is observed according to the contact position between the clamping rod 2 and the first scale plate 3 or the second scale plate 4. In summary, the first scale plate 3 and the second scale plate 4 cooperate with each other, so as to stably measure the depth of the foundation pit, improve the accuracy of the measurement, and fit the bottom position in the foundation pit through the support seat 53, so as to perform multi-angle measurement of the uneven terrain in the foundation pit, and improve the adaptability of the measurement.

[0022] like Figure 1 and Figure 4 As shown, it also includes a clamping mechanism 6, which includes a first fixed frame 61, a rotating plate 62, a second fixed frame 63, a clamping piece 64 and a second torsion spring 65. The first fixed frame 61 is connected to the rear side of the base 1, and a rotating plate 62 for rotation auxiliary limiting is rotatably connected to the first fixed frame 61. A handle is connected to the upper rear side of the rotating plate 62. The left and right parts of the rotating plate 62 are both connected to the second fixed frame 63. The second fixed frame 63 is rotatably connected with a clamping piece 64 for limiting the first scale plate 3 and the second scale plate 4. A power-assisting groove is opened in the middle of the clamping piece 64. The second torsion spring 65 is connected between the upper and lower sides of the clamping piece 64 and the adjacent second fixed frame 63. The clamping piece 64 is clamped between the first scale plate 3 and the second scale plate 4.

[0023] It should be noted that when storing the first scale plate 3 and the second scale plate 4, the second scale plate 4 is rotated backward and downward to reset, and then the rotating plate 62 is rotated forward and upward, and at the same time, the two clamps 64 are rotated to the non-adjacent side to open. At this time, the second torsion springs 65 are forced to rotate, so that the front side of the rotating plate 62 and the second scale plate 4 are fitted together, and then the two clamps 64 are released. At this time, the torsion springs are rotated in the opposite direction to reset, so that the torsion springs drive the adjacent clamps 64 to rotate to the adjacent side, and then the clamps 64 are clamped to the first scale plate 3 and the second scale plate 4. In summary, through the cooperation between the rotating plate 62 and the clamps 64, the clamps 64 are clamped to the first scale plate 3 and the second scale plate 4, thereby reducing the storage volume and improving the convenience of storage.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
