Description

Technical Field

[0001] The utility model belongs to the technical field of channel construction, in particular to a channel slope sampling device. Background Art

[0002] Channel construction is the same as pipeline construction, which requires grooving the ground first. Compared with pipeline construction, channel construction needs to be open and does not require backfilling. During channel construction, the inside of the channel is leveled and compacted, and then a concrete mortar layer is attached according to the slope and bottom of the channel to prevent water overflow and reduce the impact on the channel.

[0003] Core sampling is an essential process in concrete construction. By drilling cylindrical core samples from the concrete structure, the thickness of the concrete layer can be observed, and then these core samples can be subjected to compressive strength tests to evaluate the actual strength of the concrete. This method directly reflects the actual physical properties of the concrete, so the data is more accurate and reliable.

[0004] Among them, a search found that there is an application number 202322543225.9 for a concrete structure core sampling device. Compared with the traditional core sampling machine, when sampling vertical walls, the worker needs to drill a hole in the wall, then install an expansion bolt or nut in the hole, and then fix the concrete sampling base to the wall with the bolt or nut before drilling the core. The device can quickly adjust the vertical wall to sample, which is more convenient. Among them, the shortcomings are as follows:

[0005] Many existing core sampling devices are designed for use on horizontal or vertical surfaces. However, in channels, the slope of the channel is often inclined, which makes it difficult to place these devices during sampling. Due to the side sliding force of the inclined surface, it is difficult to fix them. Therefore, it is necessary to improve and adjust the existing ones to enhance their adjustability. At the same time, improvements should be made to the sampling devices to achieve better sampling results and improve the flexibility and practicality of the sampling devices. Utility Model Content

When the measuring rod 3 is inserted into the measuring hole 203, the arm 101 and the arm connecting rod 102 are adjusted. By observing the scale on the surface of the measuring rod 3, when the three scales are the same, it can be proved that the support plate 2 is parallel to the channel slope.

[0029] One side of the bottom of the support plate 2 is rotatably connected to a passive gear 501 through a central axis, and a linkage plate 5 is fixedly installed on the other end of the passive gear 501. A reducer 4 is installed in the middle of the bottom of the support plate 2, and the output shaft of the reducer 4 is rotatably connected to the reducer gear 401. A reducer motor 402 is installed at the input shaft of the reducer 4, and the output shaft of the reducer motor 402 is connected to the power input shaft of the reducer 4.

The reducer gear 401 links the passive gear 501 and the linkage plate 5 to rotate synchronously. This design makes the entire device more convenient and diverse in terms of the selection of sampling points when in use;

[0030] A retractable core drilling sampling structure is provided on the linkage plate 5;

[0031] The core sampling structure includes a telescopic electric cylinder 502, a movable plate 6, a motor 7, a hydraulic coupler 701, and a coring drill bit 702.
