Description

Technical Field

[0001] The utility model relates to the technical field of support dustproof devices, and in particular to a support dustproof device with a sand and wind protection function. Background Art

[0002] With the rapid development of bridges in my country, the bearings are also required to be used in different environments. The existing bearing dust prevention devices mainly use polyurethane panels and rubber panels to surround the bearings and fix them with pressure strips to achieve dust prevention effects.

[0003] Since the existing support dustproof device is not connected to the lower support plate of the support, the dustproof device and the support are not completely sealed, and the space between the dustproof device and the support is an open space. When the support is in a windy and sandy environment, such as Gobi, desert and other special environments, the existing support dustproof device cannot protect the support well, and the service life and performance of the support will be significantly reduced, requiring regular maintenance and replacement, and the cost of use is high.

[0004] In a windy and sandy environment, the structural performance of railway bridge bearings will degrade, and may even lead to bearing failure. Therefore, higher requirements are placed on the protection of the bearings. Utility Model Content

[0044] The upper steel section 2 is installed around the upper support plate 81 of the support 8 , and the lower steel section 3 is installed around the lower support plate 82 of the support 8 .

[0045] The upper steel section 2 includes two upper transverse steel sections 21 and an upper longitudinal steel section 22. The length direction of the upper transverse steel section 21 is along the transverse direction of the bridge, and the two upper transverse steel sections 21 are respectively installed on the longitudinal sides of the upper support plate 81. The length direction of the upper longitudinal steel section 22 is along the longitudinal direction of the bridge, and the two upper longitudinal steel sections 22 are installed on the transverse sides of the upper support plate 81.

[0046] The upper transverse steel 21 and the upper longitudinal steel 22 are connected by the arc steel 1, and the arc steel 1 transitionally connects the upper transverse steel 21 and the upper longitudinal steel 22 through a smooth arc segment. The upper transverse steel 21, the upper longitudinal steel 22 and the arc steel 1 together form an upper rounded rectangular annular mounting frame.

[0047] The lower steel section 3 includes two lower transverse steel sections 31 and a lower longitudinal steel section 32. The length direction of the lower transverse steel section 31 is along the transverse direction of the bridge. The two lower transverse steel sections 31 are respectively installed on the longitudinal sides of the lower support plate 82. The length direction of the lower longitudinal steel section 32 is along the longitudinal direction of the bridge. The two lower longitudinal steel sections 32 are installed on the transverse sides of the lower support plate 82.

[0048] The lower transverse steel 31 and the lower longitudinal steel 32 are connected by the arc steel 1, and the arc steel 1 transitionally connects the lower transverse steel 31 and the lower longitudinal steel 32 through a smooth arc segment. The lower transverse steel 31, the lower longitudinal steel 32 and the arc steel 1 together form a lower rounded rectangular annular installation frame.

[0049] In this embodiment, the upper steel section 2 and the lower steel section 3 are fixed to the upper support plate 81 and the lower support plate 82 respectively by screws 6 .

[0050] The drum-shaped elastic enclosure 5 is arranged around the support 8 to surround the support 8. The drum-shaped elastic enclosure 5 is drum-shaped, with the middle part protruding outward. The upper end of the drum-shaped elastic enclosure 5 is fixed on the upper rounded rectangular annular mounting frame, specifically installed on the upper steel 2 and the arc-shaped steel 1 located above, and the lower end of the drum-shaped elastic enclosure 5 is fixed on the lower rounded rectangular annular mounting frame, specifically installed on the lower steel 3 and the arc-shaped steel 1 located below.

[0051] The drum-shaped elastic enclosure 5 is designed to be drum-shaped, which contains the support 8, can better adapt to the displacement of the support 8, and completely seals the sliding surface of the support 8, with good sealing effect and good dustproof effect. It can still be used in a windy and sandy environment and can prevent dust and sand.

[0052] In this embodiment, the drum-shaped elastic enclosure plate 5 is made of a flexible material that is corrosion-resistant, aging-resistant and has a long service life.

[0053] After the drum-shaped elastic enclosure plate 5 surrounds the support 8 in one circle, the two ends of the drum-shaped elastic enclosure plate 5 are connected together by bolts 7 and nuts 4 to form a joint.

[0057] In this embodiment, the longitudinal direction refers to the direction along the bridge, and the transverse direction refers to the direction across the bridge.

[0058] The support dustproof device of the utility model has the function of preventing wind and sand. The utility model uses the drum-shaped elastic enclosure 5 and the steel section to fully seal the support 8 to achieve the effect of preventing dust and sand. In particular, due to the transition of the arc steel section 1, the connection gap at the corner is reduced, so that the drum-shaped elastic enclosure 5 can fit more closely around the support 8, effectively overcoming the problem of functional failure of the support in the special environment of wind and sand, and ensuring the performance and service life of the support.
