Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, belong to the scope of protection of the invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "vertical", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings. The "longitudinal" direction refers to the length direction of the bridge and is consistent with the extending direction of the line, and the "transverse" direction refers to the width direction of the bridge and is perpendicular to the extending direction of the line.
The embodiment of the invention provides a telescopic structure of a magnetic suspension bridge, which comprises a joint structure 100 used between stator assemblies 400, wherein the joint structure 100 comprises a light shielding plate 120 and a packing body 130; the shading plate 120 is bridged on the guard plates 110 outside the two adjacent stator assemblies 400; the packing body 130 is filled in a space between adjacent two of the sheathing plates 110 and is connected to the light shielding plate 120.
The seam structure 100 is located at the joint of two adjacent stator assemblies 400, and is used for blocking rainwater from entering the seam between the two adjacent stator assemblies 400, so that the stator assemblies 400 are helped to be waterproof, and the rainwater is prevented from damaging the stator assemblies 400. As shown in fig. 1, both ends of the light shielding plate 120 are respectively connected with the guard plates 110 outside the two adjacent stator assemblies 400, and the light shielding plate is bridged over the joint to prevent rainwater from entering the joint. The filler 130 fills the seams and is attached to the bottom of the visor 120 to further prevent rain from entering the seams.
The packing body 130 is generally made of an elastic material such as rubber. Better accommodating seam variations.
The light shielding plate 120 is made of an opaque material, such as a metal plate like a steel plate. The direct incidence of sunlight on the filler body 130 is avoided, the aging resistance of the filler body 130 is improved, and the joint structure 100 is simple in structure and durable in use.
The light shielding plate 120 may be installed in an installation groove 111 formed through the shield plate 110 described below. Preferably, as shown in FIG. 1, the top of the visor 120 is flush with the shield 110 to better maintain the integrity of the visor 120 with the shield 110.
The overall height of the seam structure 100 is preferably also not higher than the height of the cover sheet 110 in the vertical height. Preferably, an end of the packing body 130 away from the light shielding plate 120 is provided with a groove 131. The presence of the groove 131 prevents the caulk body 130 from spilling when accommodating joint changes.
The shape and number of the grooves 131 can be arbitrarily adjusted according to the needs, for example: the bottom of the packing body 130 is provided with an arc-shaped groove 131 as shown in fig. 1 and 2. For another example: the bottom of the packing body 130 is provided with more than two arc-shaped grooves 131, or the bottom of the packing body 130 is provided with at least one rectangular groove, or at least one triangular groove.
Without limitation, the cross-sectional shape of the plug body 130 is trapezoidal. The trapezoidal packing body 130 is more beneficial to receiving the clamping of the two side guard plates 110, and ensures that the packing body 130 cannot fall off. The cross-sectional shape of the gripping plug body 130 may be a trapezoid with a small top and a large bottom, but preferably, the cross-sectional shape of the plug body 130 is a trapezoid with a small top and a large bottom as shown in fig. 1.
It will be appreciated that the cross-sectional shape of the plug 130 is not limited to that described above, and the shape of the seam need to match the shape of the plug 130.
Further, the area of the light shielding plate 120 is larger than the area of the end surface of the plug 130 near the end of the light shielding plate 120. This ensures that the shield 120 completely covers the joint between the stator assemblies 400 and prevents the top of the packing body 130 from being exposed, thereby further improving the effect of blocking rainwater.
When the joint structure 100 is installed, the bridge is transversely inserted into the joint, and the bridge is pulled out and then inserted during replacement, so that the installation and maintenance are simple and convenient.
The light shielding plate 120 and the packing body 130 may be connected by bonding, scarf joint, or by fastening members. Specifically, the seam structure 100 further includes a first fastener 140; the first fastening member 140 is inserted through the packing body 130 and connected to the light shielding plate 120.
Further, the first fastener 140 includes a first bolt 141, a first nut 143 and a first washer 142, as shown in fig. 1, wherein the first bolt 141 is inserted through the packing body 130, and one end of the first bolt 141 is connected to the light shielding plate 120; the first nut 143 is sleeved on the other end of the first bolt 141, the first washers 142 are all sleeved outside the first bolt 141, one end of each first washer 142 abuts against the packing body 130, and the other end abuts against the first nut 143.
The light shielding plate 120 is integrally connected with the packing body 130 by the first fastening member 140, so that the installation is convenient. One end of the first bolt 141 may be connected to the light shielding plate 120 by welding, and the other end is threadedly connected to the first nut 143, which is convenient for installation. The first washer 142 can increase a contact area with the packing body 130, preventing the first nut 143 from being loosened.
It is to be understood that the first bolt 141 may be replaced with a screw, a stud, or the like.

If the waterproof groove 210 has the flap 211, the second bolt 221 is provided with the flap 211 and the bead 240 in this order. One side of the pressing strip 240 is attached to the side wall of the waterproof groove 210, the other side of the pressing strip is attached to the second gasket 223, the second nut 222 and the second gasket 223 are sleeved outside the second bolt 221, the second gasket 223 is located between the pressing strip 240 and the second nut 222, and the second nut 222 is in threaded connection with the second bolt 221 to fasten the installation of the waterproof groove 210.
