Technical Field

[0001] The utility model relates to the field of airport pavement construction, in particular to a Beckmann beam wind shielding device. Background Art

[0002] At present, the Beckmann beam tests on the subgrade reaction modulus of airport pavement projects and municipal road projects are all conducted in open-air. Due to the influence of wind, the Beckmann beam often shakes and displaces during the test, making it difficult to ensure the accuracy of the test data. What's worse, multiple tests are required to obtain accurate data, which is time-consuming and labor-intensive. Utility Model Content

Since the Beckman beam targeted by the utility model is relatively long, exceeding 1.5 meters, the use of the inner and outer stacking structure can reduce the storage space.

[0007] The outer side of the inner sliding plate is symmetrically provided with raised slide rails, and the inner side of the outer sliding plate is correspondingly provided with concave slide grooves matching with the raised slide rails, and the inner sliding plate and the outer sliding plate move relative to each other by means of the slide rails and the slide grooves, so that the two slide smoothly.

[0008] The outer surface of the inner sliding plate is provided with a limit block, one on each side, at the edge of the same side, which can prevent the inner sliding plate from completely overlapping with the outer sliding plate, making it difficult to pull out, and the inner sliding plate can be pulled out and unfolded with the help of the left and right limit blocks.

[0009] The utility model has the advantages of simple overall structure, convenient manufacture and low cost, and can well protect the Beckmann beam from external influences during detection even in abnormal weather, thereby ensuring the accuracy of detection data.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Embodiment 1, as Figure 1-3As shown, a Beckman beam windshield device includes a windshield module and a transport module 2. The windshield module 1 is composed of two rectangular plates connected at an acute angle. In this example, an aluminum alloy plate is used. The aluminum alloy plate with a length × width of 1.8 meters × 0.7 meters is bent into an acute angle (30 degrees) from the middle. The transport module 2 is fixed to the surface of the windshield module 1, at least one on each side, and 4 in the figure, 2 on each side symmetrically. The transport module 2 is composed of a base fixing plate 201, a return spring 202, and a transport handle 203. The base fixing plate 201 is fixed to the windshield module 1 by screws. The base fixing plate 201 is provided with an engaging groove that matches the transport handle 203. The transport handle 203 is hinged to the base fixing plate 201 by a pin and a return spring 202. After the person who transports it to the storage location lets go, the transport handle automatically returns to its original position by relying on the return spring.

[0021] Embodiment 2, as Figure 4-8 As shown, the windshield module 1 is composed of an internal sliding plate 101 and an external sliding plate 102. The internal sliding plate and the external sliding plate are respectively composed of two rectangular plates connected at an acute angle, and are also made of aluminum alloy plates. The internal dimensions of the internal sliding plate are the same as those of the internal dimensions of Example 1 except that the length is 1 meter. The other angles and heights are the same. The internal sliding plate and the external sliding plate are stacked together, and the base fixing plate 201 is fixed to the outer surface of the external sliding plate.

[0022] The outer side surface of the inner sliding plate is symmetrically provided with raised slide rails 103, and the inner side surface of the outer sliding plate is correspondingly provided with concave slide grooves 104 that match the raised slide rails 103. The inner sliding plate and the outer sliding plate move relative to each other by the cooperation of the two.

[0023] The transport module 2 is fixed on the outer surface of the outer sliding plate, and the outer surface of the inner sliding plate is provided with a limiting module 3, one on each side, at the edge of the same side. The limiting module is 1 cm thick, 1 cm wide, and 10 cm long. It is fixed to the outer surface edge of the inner sliding plate through a fixing member. The inner sliding plate and the outer sliding plate are of equal length, or the outer sliding plate is shorter than the inner sliding plate by a limiting module width, that is, the overlapping parts of the two are of equal length. The limiting module can prevent the inner sliding plate from completely overlapping with the outer sliding plate, making it difficult to pull out, and can also be used as a handle to pull out and unfold the inner sliding plate. In terms of length, the inner sliding plate and the outer sliding plate generally retain an overlapping area of ​​10 cm after unfolding. The remaining undescribed parts are the same as those in Example 1.
