Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a rail transportation sand prevention net with good stability. Background Art

[0002] Rail transit sand prevention net is a protective facility installed along the rail transit line to prevent foreign objects such as sand and gravel from entering the rail transit area. It has certain strength and corrosion resistance and can withstand the influence of natural environments such as wind, sun, and rain. The mesh size and shape of the sand prevention net can be designed according to actual needs to ensure that dust and gravel are effectively blocked without affecting the normal operation of rail transit.

[0003] However, in certain specific rail environments, such as areas with strong winds and sand or near dusty construction sites, large amounts of sand and dust can easily damage rail transit equipment.

[0004] In this case, traditional sand control measures may have the problem of insufficient stability. For example, ordinary sand control nets may become loose, deformed or even damaged in strong winds or during long-term use, resulting in reduced sand control effects, which in turn affects the normal operation of rail transit and the safety and reliability of equipment. For this reason, we provide a rail transit sand control net with good stability. Utility Model Content

DETAILED DESCRIPTION

[0025] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a rail transit sand prevention net with good stability, including a sand prevention net body 1, the sand prevention net body 1 is made of stainless steel, which can achieve the high-strength anti-aging effect of the sand prevention net body 1, and a base 2 is arranged at the bottom of the sand prevention net body 1, and screws 3 are penetrated through the surface of the sand prevention net body 1, and the screws 3 are threadedly connected to the inside of the base 2, and a positioning component 5 and a movable component 4 are arranged inside the base 2. When the slip ring 42 slides upward, it will drive the movable plate 48 to slide upward, and when the movable plate 48 slides upward, it will drive the positioning plate 46 and the positioning rod 47 to slide upward and unfold, and the movable component 4 includes: a fixed rod 41, a slip ring 42, a connecting ring 43, a fixed block 44, a connecting block 45, a positioning plate 46, a positioning rod 47, and a movable plate 48.

[0026] A fixing rod 41 is fixedly installed inside the base 2, a slip ring 42 is slidably connected inside the fixing rod 41, the screw 3 is threadedly connected inside the slip ring 42, a connecting ring 43 is fixedly installed on the surface of the slip ring 42, the connecting ring 43 is slidably connected to the surface of the fixing rod 41, a fixing block 44 is fixedly installed on the surface of the fixing rod 41, a connecting block 45 is fixedly installed on the surface of the fixing block 44, a positioning plate 46 is hinged on the outside of the connecting block 45, a positioning rod 47 is fixedly installed on the top of the positioning plate 46, one end of a movable plate 48 is hinged on the bottom of the positioning plate 46, and the other end of the movable plate 48 is hinged on the outside of the connecting ring 43. When the positioning plate 46 is unfolded, the force area of ​​the sand control net body 1 during installation can be increased to prevent the screw 3 from loosening, thereby improving the stability of the installation of the sand control net body 1 and the base 2.

[0027] The positioning assembly 5 includes: a connecting plate 51, the connecting plate 51 is fixedly mounted on the surface of the fixing block 44, the top of the connecting plate 51 is slidably connected with an insert block 52, an insert rod 54 is fixedly mounted on the inner side of the insert block 52, a fixing spring 53 is fixedly mounted on the outer side of the insert block 52, and the fixing spring 53 is fixedly mounted on the inner side of the connecting plate 51. When the positioning rod 47 slides upward, it will penetrate the connecting plate 51. When the positioning rod 47 penetrates the connecting plate 51, it will contact the outer side of the insert block 52, thereby contacting the insert block 52 to move toward the surface close to the screw 3. When the insert block 52 moves, it will drive the insert rod 54 slides in the moving direction of the plug block 52, so as to be inserted into the surface of the screw 3 to limit the use of the screw 3, thereby improving the stability and fixing effect of the screw 3.

[0028] When the sand-proof net body 1 is in use, it is often connected to the base 2 by means of screws 3. When the sand-proof net body 1 is used for a long time and is installed in an area with strong sandstorms, the screws 3 may become loose. When the screws 3 become loose, they may slide upward inside the base 2. When the screws 3 slide, they may drive the slip ring 42 to slide upward inside the fixed rod 41. When the slip ring 42 slides upward, it may drive the movable plate 48 to slide upward. When the movable plate 48 slides upward, it may drive the positioning plate 46 and the positioning rod 47 to slide upward and unfold. When the positioning plate 46 is unfolded, the force-bearing area of ​​the sand-proof net body 1 during installation may be increased, thereby preventing the screws 3 from loosening and improving the stability of the installation of the sand-proof net body 1 and the base 2.

[0029] When the positioning rod 47 slides upward, it will penetrate the connecting plate 51. When the positioning rod 47 penetrates the connecting plate 51, it will abut against the outer side of the plug block 52, thereby abutting against the plug block 52 to move toward the surface close to the screw 3. When the plug block 52 moves, it will drive the plug rod 54 to slide in the same moving direction as the plug block 52, thereby being inserted into the surface of the screw 3 to limit it, thereby improving the stability and fixing effect of the screw 3.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
