Description

Technical Field

[0001] The utility model relates to the technical field of wood component detection, in particular to anti-shaking internal detection equipment for wood components of ancient buildings. Background Art

[0002] In order to ensure the stability of ancient buildings, it is necessary to inspect the interior of the wooden components of ancient buildings through detection equipment, and the commonly used detection method is ultrasonic detection, in which ultrasonic detection refers to the one-dimensional stress wave caused in a uniform isotropic prism according to the basic stress wave theory. The propagation speed of the stress wave has a certain relationship with the density of the prism material. However, the existing internal detection equipment of the wooden components of ancient buildings still has some defects during use;

[0003] For example, an internal detection device for wooden components of ancient buildings proposed in the application number CN202222825177.8 belongs to the technical field of wood structure detection, and its technical points are: including a frame, a lifting assembly and a rotating assembly. The internal of the wooden components of the ancient buildings can be detected by the detector sensor, and the detection results can be displayed by the detector body. When the height of the detector sensor needs to be adjusted, the lifting assembly is turned on, and the lifting assembly can drive the detector sensor to lift, so that the detector sensor can detect different heights of the wooden components of the ancient buildings. In the actual use process, the internal detection device of the wooden components of the ancient buildings uses the cylinder in the lifting assembly to drive the detector sensor to lift, but the transmission distance of the cylinder is limited. When the wooden components of the ancient buildings are high, the detection of different heights cannot be achieved by lifting the cylinder, resulting in an increase in the limitations of the internal detection device of the wooden components of the ancient buildings. At the same time, during the lifting process, the detector sensor is prone to shaking, resulting in a decrease in the detection effect, and the detector sensor is not convenient for disassembly and storage and replacement after damage.

[0004] Therefore, we proposed an anti-sway internal inspection device for wooden components of ancient buildings in order to solve the above-mentioned problems. Utility Model Content

[0029] See also Figure 1-5 The utility model provides a technical solution: an anti-swaying internal detection device for wooden components of ancient buildings, comprising a front positioning seat 1, a rear positioning seat 2, an intermediate seat 8 and a detector sensor 10, the front positioning seat 1 and the rear positioning seat 2 are symmetrically distributed about the center line of the intermediate seat 8, the outer sides of the front positioning seat 1 and the rear positioning seat 2 are fixedly installed with a connecting seat 3, the interior of the front positioning seat 1 is rotatably installed with a driving wheel 4, the interior of the rear positioning seat 2 is rotatably installed with a driven wheel 5, the driving wheel 4 and the driven wheel 5 are symmetrically distributed on the inner sides of the front positioning seat 1 and the rear positioning seat 2, one end of the driving wheel 4 is connected to a servo motor 6, and The servo motor 6 is fixedly connected to one side of the front positioning seat 1. The design of the above structure enables the servo motor 6 to drive the driving wheel 4 to rotate inside the front positioning seat 1 when the driving wheel 4 and the driven wheel 5 are in contact with the two sides of the wooden components of the ancient building. The friction between the driving wheel 4 and the wooden components of the ancient building is used to drive the internal detection equipment of the wooden components of the ancient building to be lifted and lowered. During the lifting process, the driven wheel 5 will also rotate drivenly by the friction between the wooden components of the ancient building, so as to reduce the friction between the wooden components of the ancient building during the lifting process, thereby improving the lifting stability and anti-swaying effect.

[0030] The limiting plates 7 are symmetrically distributed on both sides of the middle seat 8, and the inner sides of the limiting plates 7 are tightly fitted with the front positioning seat 1 and the rear positioning seat 2, and the limiting plates 7 limit the adjustment sliding of the front positioning seat 1 and the rear positioning seat 2. The middle seat 8 is connected to the front positioning seat 1 and the rear positioning seat 2 through an adjusting mechanism 9. The adjusting mechanism 9 includes a positioning plate 901, and a positioning plate 901 is symmetrically installed on one side of the middle seat 8. A rotating shaft 902 is inlaid inside the positioning plate 901, and an adjusting screw 903 is installed through the inside of the rotating shaft 902. The threads on the adjusting screw 903 are symmetrically opened from the center to both ends. A knob 904 is fixedly installed in the middle of the adjusting screw 903.

The outer ring of the threaded sleeve 905 is fixedly sleeved with a connecting rod. The connecting plate 906, the connecting plates 906 at both ends are fixedly connected to the front positioning seat 1 and the rear positioning seat 2 respectively.

The card block 1102 is connected through The spring 1105 and the limiting groove 1101 form a telescopic structure, and the block 1102 is engaged and connected with the socket 1106. The design of the above structure enables the block 1102 to be extended and retracted inside the limiting groove 1101 by squeezing the block 1102 and resetting it by the spring 1105, thereby controlling the engagement and separation between the block 1102 and the socket 1106, which is beneficial for disassembly, storage and replacement of the socket 1106 and the detector sensor 10 when separated, and is also beneficial for positioning and installing the detector sensor 10 when engaged, wherein the limiting rod 1104 can limit the extension and retraction of the block 1102 through the inner groove 1103, thereby improving the stability of the engagement and separation of the block 1102.

[0033] When the detector sensor 10 needs to be disassembled, the block 1102 is squeezed to shrink it into the limiting groove 1101 and the block 1102 is released from the holder 1106. At this time, the detector sensor 10 and the holder 1106 can be separated from the middle seat 8 to complete the disassembly. During installation, the detector sensor 10 and the holder 1106 are attached to the middle seat 8, and then the spring 1105 is used to push the block 1102 out so that the block 1102 can be engaged with the holder 1106, thereby realizing the positioning installation of the holder 1106 and the detector sensor 10.
