Description

Technical Field

[0001] The utility model relates to an anti-vibration gripper for a suspended filter in an anti-vibration electrical control cabinet for a train, belonging to the technical field of electrical control equipment. Background Art

[0002] The electrical control cabinet for a train is a special cabinet for train electric and pneumatic control. The electrical components in the cabinet must not be contaminated by dust, and the gas supplied into the cabinet is generally filtered by a filter and then transported into the cabinet. Therefore, relatively strict airtightness is required.

[0003] For trains running in desert areas (such as Saudi Arabia and other Arab countries), due to the soft and uneven geological conditions in this area, the roadbed where the sleepers are laid has irregular settlement amplitudes when stressed, and coupled with the sand and wind with constantly changing intensity and direction, the vibration intensity of the train operation is far greater than that of trains running on domestic lines. For an electrical control cabinet that can be normally used to the set service life in China, if no special anti-vibration protection is provided, in this area, sometimes accidents such as the loosening of the lock body, the automatic opening or deformation of the cabinet door will occur after only one one-way trip, resulting in the influx of sand and wind into the cabinet, which is extremely difficult to clean. Moreover, the content of air acid, alkali and salt in this area is very high, and the electrical components in the cabinet are extremely vulnerable to corrosion when exposed to the air after the cabinet door is damaged, greatly shortening the service life of the electrical control components. Summary of the Utility Model

[0004] To solve the above problems, our company has developed an anti-vibration electrical control cabinet for a train (a patent application was filed on the same day as this application). This control cabinet focuses on the cabinet door, but also involves the anti-vibration clamping of an air filter (providing pure air for a pneumatic device) vertically suspended in the cabinet. The air filter vertically suspended in the electrical control cabinet in the prior art operates safely and reliably on domestic rail lines, but is extremely vulnerable to damage when running in the above-mentioned desert areas with strong vibration and frequent sand and wind attacks. If its violent vibration is not controlled, it will also greatly affect the air filtration effect.

[0005] The technical problem to be solved by the utility model is: how to implement anti-vibration clamping on an air filter vertically suspended in the cabinet.

[0006] In view of the above problems, the technical solution proposed by the utility model is:

[0007] An anti-vibration gripper for a suspended filter in an anti-vibration electrical control cabinet for a train, comprising a clamping control plate horizontally fixed on a vertically installed plate in the electrical control cabinet, wherein the clamping control plate is provided with a clamping hole communicating up and down, and the filter element container of the vertically suspended filter is clamped in the clamping hole.

[0008] On the clamping control plate at the front of the clamping hole, there is a clamping notch through which the clamping hole communicates with the external space, so that the left clamping arm and the right clamping arm in a pincer-like clamping shape are formed on the left and right sides of the clamping hole and the clamping notch of the clamping control plate. The left clamping arm and the right clamping arm clamp and fix the rhombic convex block on the outer side of the filter element container from the left and right sides.

[0009] The front ends of the left clamping arm and the right clamping arm are respectively bent vertically downward to form the left wall plate and the right wall plate of the clamping notch, and the rhombic convex block is clamped by the left wall plate and the right wall plate.

[0010] There is a damping rubber layer on the right side of the left wall plate and the left side of the right wall plate.

[0011] It also includes a clamping mechanism arranged between the left wall plate and the right wall plate to clamp the left wall plate and the right wall plate.

[0012] The clamping mechanism includes mounting holes respectively arranged on the front sides of the left wall plate and the right wall plate and a clamping rod with both ends mounted in the mounting holes. Annular mounting grooves are provided on the outer circumferences of both ends of the clamping rod. An arc-shaped elastic convex rib is provided on one side of the middle of the clamping rod for pressing the front side of the rhombic convex block after rotation. The mounting grooves at both ends of the clamping rod are respectively located at the positions of the mounting holes of the left wall plate and the right wall plate, and the front edge of the mounting hole is clamped into the mounting groove.

[0013] The mounting hole is an oval hole capable of inserting the clamping rod with an elastic convex rib.

[0014] A hexagonal screw handle for wrench rotation is provided at one end of the clamping rod. Beneficial effects

[0015] 1. It can implement clamping control of the hanging filter element container against horizontal vibration, prevent the filter element container from shaking horizontally during strong vibration, and prevent the installation and fixing components from loosening;

[0016] 2. It can maintain the normal filtering function of the filter element container and prevent the filtering function of the filter element from failing during high-frequency vibration. Description of the drawings

[0024] The following further describes the present utility model with reference to the accompanying drawings: <( Embodiment 1

[0025] As Figure 1 —3 shows, a vibration-resistant gripper for a suspension-mounted filter in a train's vibration-resistant electrical control cabinet includes a clamping control plate 1 horizontally fixed on a vertical mounting plate 31 inside the electrical control cabinet 3. The clamping control plate 1 is provided with a clamping hole 11 that communicates up and down. The filter element container 41 of the vertically suspended filter 4 is clamped in the clamping hole 11. In this way, clamping control of the vertically suspended filter element container 41 against horizontal vibration can be implemented, preventing the filter element container 41 from horizontally shaking during strong vibration, preventing the mounting and fixing parts from becoming loose, and at the same time being able to maintain the normal filtering function of the filter element container 41.

[0026] On the clamping control plate 1 in front of the clamping hole 11, there is a clamping notch 12 through which the clamping hole 11 communicates with the external space, so that the left clamping arm 13 and the right clamping arm 14 that are in a pincer-like clamping shape are formed on the left and right sides of the clamping hole 11 and the clamping notch 12 of the clamping control plate 1. The left clamping arm 13 and the right clamping arm 14 clamp the rhombic convex block 411 on the outer side of the filter element container 41 from the left and right sides. In this way, by only clamping the two sides of the rhombic convex block 411, horizontal vibration-resistant control of the filter element container 41 is basically achieved.

[0027] The front ends of the left clamping arm 13 and the right clamping arm 14 are respectively vertically folded downwards to form a left wall plate 131 and a right wall plate 141 of the clamping notch 12, and the rhombic convex block 411 is clamped by the left wall plate 131 and the right wall plate 141. There is a vibration damping rubber layer 16 on the right side of the left wall plate 131 and the left side of the right wall plate 141. Embodiment 2

[0028] As <[ Figure 4As shown in FIGS. 6, the difference from the first embodiment is that the anti-vibration gripper further includes a clamping mechanism disposed between the left wall plate 131 and the right wall plate 141 to clamp the left wall plate 131 and the right wall plate 141. The clamping mechanism includes mounting holes 15 respectively disposed on the front sides of the left wall plate 131 and the right wall plate 141, and clamping rods 2 with both ends mounted in the mounting holes 15. Annular mounting grooves 21 are provided on the outer circumferences of both ends of the clamping rod 2. An arcuate elastic convex rib 22 is provided on one side of the middle of the clamping rod 2 for pressing the front side of the rhombic convex block 411 after rotation. The mounting grooves 21 at both ends of the clamping rod 2 are respectively located at the positions of the mounting holes 15 of the left wall plate 131 and the right wall plate 141, and the front edge of the mounting hole 15 is snapped into the mounting groove 21. In this way, anti-vibration clamping is also implemented on the front side of the rhombic convex block 411.

[0029] The mounting hole 15 is an oblong hole into which the clamping rod 2 with the elastic convex rib 22 can be inserted. The clamping rod 2 is rotated to snap the front edge of the mounting hole 15 into the mounting groove 21.

[0030] Further, a hexagonal screw handle 23 for wrench rotation is provided at one end of the clamping rod 2, so that the clamping rod 2 can be rotated by using a wrench, thereby pressing the elastic convex rib 22 against the front side of the rhombic convex block 411.

[0031] The above embodiments are only used to describe the present invention more clearly, and should not be regarded as limiting the protection scope covered by the present invention. Any modification in an equivalent form should be regarded as falling within the protection scope covered by the present invention.
