DETAILED DESCRIPTION

[0023] Example:

[0024] Combination Figure 1 , Figure 4 and Figure 5As shown, the utility model provides a sampling device for the roof of a train compartment, including a connecting frame 1 installed on an external lifting device, the external lifting device can be a car body located outside the compartment, or a lifting device fixed to the compartment, the connecting frame 1 is equipped with a connecting arm 2 for adjusting the position of a sampling structure 3, and the connecting arm 2 is equipped with a sampling structure 3. The connecting frame 1 can be used to stably fix the connecting arm 2 on the external lifting device, and the connecting arm 2 can adjust the position of the sampling structure 3 so that the sampling structure 3 is located at the center of the train compartment. The sampling structure 3 includes a sampling portion 35 for sampling, and the sampling portion 35 includes an upper sleeve 357, and the upper sleeve 357 is provided with two connecting ears, and the upper sleeve 357 is equipped with a sampling sleeve 3 through the connecting ears. 56. The upper sleeve body 357 and the sampling sleeve 356 are both hollow hemispherical. The outer diameter of the sampling sleeve 356 is not larger than the inner diameter of the upper sleeve body 357. The sampling sleeve 356 is installed on the upper sleeve body 357 through a connecting shaft. The sampling sleeve 356 can rotate freely on the upper sleeve body 357. By utilizing the rotation of the sampling sleeve 356 and the hollow characteristics of the sampling sleeve 356, when the sampling sleeve 356 rotates, the sample can be placed in the hollow position of the sampling sleeve 356, thereby realizing the sampling function. Different from the traditional sampling method through spiral blades, since the spiral blades also have a crushing function during the transmission process, they will destroy the original state of the sample. The present application can retain the original state of the sample to the greatest extent by rotating the sampling sleeve 356 and utilizing the digging principle.

[0025] The material of the upper sleeve 357 and the sampling sleeve 356 can be low-alloy high-strength steel, high-hardness alloy steel or cast steel.

[0026] Low alloy high strength steel: It has good wear resistance and strength. It is usually used in excavator buckets for digging hard materials such as rocks and ores. It can improve digging efficiency and service life.

[0027] ‌High-hardness alloy steel‌: The hardness and wear resistance are higher than those of low-alloy high-strength steel. It is suitable for excavating relatively hard rocks, ores and other materials, and has a longer service life.

[0028] ‌Cast steel‌: good formability, high strength and wear resistance, and a wide range of applications‌‌.

[0029] A first sprocket 355 is coaxially mounted on the connecting shaft, a cam is provided above the upper sleeve 357, a transmission shaft 352 is mounted on the cam of the upper sleeve 357 via a bearing, the transmission shaft 352 can rotate freely on the cam, and second sprockets 353 are coaxially mounted on both ends of the transmission shaft 352, the first sprocket 355 is connected to the second sprocket 353 via a transmission chain 354, and the chain drive can drive the sampling sleeve 356 to rotate when the transmission shaft 352 rotates, thereby realizing the sampling drive control function of the sampling sleeve 356.

[0030] At least two laser scanners 359 are installed on the connecting ears of the upper casing 357, and the laser scanners 359 are symmetrically installed on both sides of the upper casing 357. Since at least two laser scanners 359 are arranged, a more comprehensive scan of the carriage can be performed. The laser scanner 359 fully covers the surface of the coal pile in the sampling carriage, and calculates the rasterized elevation data of the coal pile surface and the spatial coordinates of each feature point on the edge of the carriage through a three-dimensional point cloud processing algorithm. A camera 358 for sample monitoring is arranged at the center position inside the upper casing 357. The camera 358 can analyze the samples and measure the samples after sampling. If the number of samples taken is insufficient, secondary sampling will be performed.

[0031] A mounting groove is provided at the center position of the convex edge of the upper sleeve 357, and the mounting groove exposes the transmission shaft 352 to the outside.

[0032] A support frame 32 is installed on the convex edge of the upper sleeve body 357, and a first motor 33 is installed on the support frame 32. A second bevel gear 34 meshing with the first bevel gear 351 is installed at the output end of the first motor 33. By utilizing the meshing of the first bevel gear 351 and the second bevel gear 34, when the first motor 33 rotates, the transmission shaft 352 can be driven to rotate, thereby realizing the sampling drive control function of the sampling sleeve 356.

[0033] A connecting rod 31 is installed on the side of the support frame 32 away from the first motor 33, and the support frame 32 is installed on the connecting arm 2 through the connecting rod 31.

With this arrangement, the connecting rod 31 can rotate freely on the spherical sleeve 28. Since the upper sleeve body 357 and the sampling sleeve 356 have a large mass and are affected by the gravity of the upper sleeve body 357 and the sampling sleeve 356, the upper sleeve body 357 and the sampling sleeve 356 can be in a direction perpendicular to the ground. When sampling, if the sampling sleeve 356 is against the coal block and the sampling sleeve 356 cannot rotate, the connection between the connecting rod 31 and the spherical sleeve 28 can be rotated to avoid damage to the coal or the sampling sleeve 356.

[0035] The slider 26 is provided with a thread on one side away from the linear drive device 27, and the thread is recessed in the slider 26. The slider 26 is coupled to the bolt 25 through the thread, so that the rotation of the bolt 25 can drive the movement of the slider 26, thereby realizing the position adjustment of the sampling part 35. The bolt 25 is installed on the arm body 21 through a bearing, and the bolt 25 is coaxially installed with a third bevel gear 24. The third bevel gear 24 is meshed with the fourth bevel gear 23 through teeth. The fourth bevel gear 23 is installed at the output end of the second motor 22. The second motor 22 can provide power for the rotation of the fourth bevel gear 23, and the second motor 22 is fixedly installed on the arm body 21 through a motor seat.
