Therefore, the drawings and the description are illustrative in nature, and are not used to limit the protection scope of the claims.

Among them, "fixed connection" refers to the relative position relationship after being connected with each other. "Rotary connection" refers to the relative rotation after being connected with each other. The orientation terms mentioned in the embodiments of the present application, such as "length", "width", "thickness", "upper", "lower", "front", "rear" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as limiting the present application by indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation.

[0025] The present application provides a cable bridge cover plate fixing device, which can adjust the fixing device according to the width and thickness of the bridge, and the fixing device is fixed by using screw rod and nut, so that the installation and fixing mode is reliable, and even in bad weather such as strong wind, the cable bridge cover plate can be protected from falling or deforming.

[0026] The cable bridge cover plate fixing device of the present application comprises a plurality of fixing assemblies arranged at intervals along the length direction of the cable bridge, and each fixing assembly has the same structure. The structure of the fixing assembly will be described below.

[0027] The fixing assembly comprises a pair of mounting plates for clamping on both sides of the thickness direction of the cable bridge on which the cover plate is mounted; a screw rod for penetrating through the pair of mounting plates; and a nut for being fixed at both ends of the screw rod.

[0028] The pair of mounting plates comprises a first mounting plate 10 and a second mounting plate 20, and oval holes are arranged at both ends of the first mounting plate 10, specifically, a first oval hole 11 and a second oval hole 12. Similarly, oval holes are arranged at both ends of the second mounting plate 20, specifically, a third oval hole 21 and a fourth oval hole 22. Exemplarily, the first mounting plate 10 and the second mounting plate 20 can both be angle steels.

[0029] The first mounting plate 10 is arranged on one side of the thickness direction of the cable bridge on which the cover plate is mounted, and the second mounting plate 20 is arranged on the other side of the thickness direction of the cable bridge on which the cover plate is mounted. For example, the cable bridge on which the cover plate is mounted is vertically installed at a distance from the wall surface, and the first mounting plate 10 can be arranged on the side of the cable bridge 60 on which the cover plate 50 is mounted close to the wall surface, and the second mounting plate 20 can be arranged on the side of the cable bridge on which the cover plate is mounted away from the wall surface.

[0030] The positions of the first and third elliptical holes 11 and 21 correspond. Specifically, for example, the first elliptical hole 11 is 20 mm away from the lengthwise edge of the first mounting plate 10, and the first elliptical hole 11 is 10 mm away from the widthwise edge of the first mounting plate 10. Then, the third elliptical hole 21 is also 20 mm away from the lengthwise edge of the second mounting plate 20, and the third elliptical hole 21 is 10 mm away from the widthwise edge of the second mounting plate 20.

[0031] The positions of the second and fourth elliptical holes 12 and 22 correspond. Specifically, for example, the second elliptical hole 12 is 20 mm away from the lengthwise edge of the first mounting plate 10, and the second elliptical hole 12 is 10 mm away from the widthwise edge of the first mounting plate 10. Then, the fourth elliptical hole 22 is also 20 mm away from the lengthwise edge of the second mounting plate 20, and the fourth elliptical hole 21 is 10 mm away from the widthwise edge of the second mounting plate 20.

[0032] The screw rod includes a first screw rod 30 and a second screw rod 40, both ends of which have external threads for screwing on screw caps. Alternatively, the screw rod can also be a one-end screw rod, and the other end is a screw cap end connected as a whole, so the screw rod only needs to have one end fixed with a screw cap.

[0033] The length of the minor axis of all elliptical holes is less than the diameter of the screw rod. For example, the diameter of the screw rod is 12 mm, and the length of the minor axis of the elliptical hole can also be 10 mm or 8 mm. Of course, the two screw rods can also have different diameters, and the corresponding elliptical holes also change accordingly, which will not be described in detail here.

[0034] The first screw rod 30 passes through the first and third elliptical holes and is screwed on the screw rod segment by the first screw cap 31, and the second screw rod 40 passes through the second and fourth elliptical holes and is screwed on the screw rod segment by the second screw cap 41. According to the thickness of the cable bridge, the position of the screw cap can be adjusted. For example, the thickness of the cable bridge is 200 mm, and the screw cap is screwed so that the distance between the first mounting plate 10 and the second mounting plate 20 is basically 200 mm.

[0035] Because there are elliptical holes on the first mounting plate and the second mounting plate, and the length of the minor axis of the elliptical hole is less than the diameter of the screw rod, the position of the screw rod in the lengthwise direction of the first mounting plate and the second mounting plate can be adjusted to adapt to the width of the cable bridge. For example, the width of the cable bridge is 400 mm, and the position of the screw rod is adjusted in the width direction of the cable bridge so that the distance between the first screw rod 30 and the second screw rod 40 is also approximately 400 mm, which can adapt to the width of the cable bridge. Of course, the distance between the first screw rod 30 and the second screw rod 40 can also be greater than 400 mm, but it should not be too large, otherwise the stability of clamping the cable bridge will be poor.

[0036] In some embodiments, the threads of the first screw are of opposite hand at the two ends, for example, the upper end of the first screw is left-handed, and the lower end is right-handed. An external hex is provided at the middle of the first screw to facilitate rotation of the first screw by a wrench. Similarly, the threads of the second screw are of opposite hand at the two ends, for example, the upper end of the second screw is left-handed, and the lower end is right-handed. An external hex is provided at the middle of the second screw to facilitate rotation of the second screw by a wrench. The first mounting plate 10 and the second mounting plate 20 can each be an angle steel having an oval hole formed on one face and a strip-shaped notch formed on the other face, the edge of the nut being embedded in the strip-shaped notch and slidable along the strip-shaped notch, the length direction of the strip-shaped notch being parallel to the length direction of the screw.

[0037] As shown in the figure, the first mounting plate 10 is an angle steel having a first oval hole 11 and a second oval hole 12 formed on one face and a strip-shaped notch 32 formed on the other face, the length direction of the strip-shaped notch being parallel to the length direction of the screw. The first screw 30 is inserted into the first oval hole 11, and the nut is screwed onto the upper end of the first screw, the edge of the nut 31 being embedded in the strip-shaped notch 32 to limit rotation of the nut. When the first screw is turned by a wrench, the nuts at the two ends of the screw move towards or away from each other simultaneously, thereby quickly adjusting the distance between the first mounting plate and the second mounting plate.

[0038] The above description is only preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
