Description

Technical Field

[0001] This utility model relates to the field of sealing technology for rail maintenance equipment, specifically a roof structure for a rail milling vehicle. Background Technology

[0002] Currently, locomotive roofs are typically connected and fixed to the supporting frame or side beams of the car body using multiple fasteners distributed around the perimeter. However, this mechanical connection method using fasteners faces significant challenges in achieving reliable sealing and rain protection. On the one hand, the fasteners themselves pass through the roof and car body structure, and their mounting holes naturally become potential channels for water seepage. On the other hand, dimensional tolerances and assembly gaps between the roof and car body frame during manufacturing and installation, as well as relative displacement caused by vibration and deformation during vehicle operation, make it difficult to guarantee a long-term, uniform, and reliable sealing effect using only traditional flat sealing strips or sealants. Therefore, there is an urgent need to develop a roof mounting structure that is closely integrated with the fastener installation method, can effectively adapt to changes in operating conditions, and achieves a durable and reliable seal to completely solve the problem of rainwater leakage. Utility Model Content

[0003] The purpose of this utility model is to provide a roof structure for a rail milling vehicle to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a roof structure for a rail milling vehicle, comprising a roof disposed above the vehicle body, wherein mounting bolts pass through both sides of the roof to form a detachable connection with the vehicle body, and inner folding plates are welded to the top of both sides of the vehicle body, the inner folding plates being located inside the mounting bolts, one inner side of the inner folding plate bending towards the roof, and a sealing strip being fitted onto the upper part of the upwardly bent side of the inner folding plate, and a sealing mating groove corresponding to the position of the sealing strip being installed on the lower side of the roof, a sealing rubber tube being installed in the sealing mating groove, and the sealing strip abutting against the sealing rubber tube so that both sides of the sealing rubber tube fit against the inner side of the sealing mating groove.

[0005] Furthermore, one side of the inner folding plate bends 90° toward the roof.

[0006] Furthermore, the sealing strip is inverted U-shaped, and an anti-detachment protrusion is provided on the inner side of the sealing strip.

[0007] Furthermore, the inner side length of the sealing strip is greater than the outer side length.

[0008] Furthermore, the roof is provided with sealing installation structures on both sides. The sealing installation structures include live screw seats fixedly connected to the vehicle body. The roof includes a roof cover plate. Side plates are connected to both sides of the roof cover plate. A seat plate is connected to the inner side of the side plate. A support plate is connected to the upper side of the seat plate. The upper end of the support plate is connected to the lower side of the roof cover plate. The seat plate has mounting screw holes that correspond to the positions of the live screw seats. The roof cover plate has mounting holes that correspond to the positions of the mounting screw holes. Mounting bolts are installed in the mounting screw holes. The lower part of the mounting bolts is threadedly connected to the live screw seats.

[0009] Furthermore, a waterproof cover is installed on the mounting hole.

[0010] Furthermore, the top cover plate is bent downwards and tilted on both sides.

[0011] Furthermore, drainage holes are provided on the side plate.

[0012] Furthermore, an elastic washer and a large washer are fitted onto the stud of the mounting bolt.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The system utilizes a 90° bend in the inner plate, an inverted U-shaped sealing strip fitted onto it, and a sealing rubber tube filling the sealing groove on the roof to form a multi-layered sealing barrier. The elastic and tight contact between the sealing strip and the sealing rubber tube ensures that both sides of the rubber tube effectively adhere to the inner wall of the sealing groove. This not only significantly increases the contact pressure at the sealing interface but, more importantly, completely blocks rainwater seepage along the mounting bolt holes, fundamentally solving the inherent water leakage problem at fastener connections.

[0014] Excellent structural adaptability and compensation capability: The inverted U-shaped sealing strip and its inner anti-detachment convex strip design, combined with the elastic sealing rubber tube, can effectively compensate for the relative displacement between the roof and the body caused by manufacturing tolerances, assembly gaps, and vibration and deformation during vehicle operation. This elastic sealing structure can maintain continuous sealing pressure, ensuring sealing reliability under dynamic operating conditions and overcoming the shortcomings of traditional planar seals that are prone to failure under deformation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 and Figure 2 As shown, this embodiment provides a roof structure for a rail milling vehicle, including: a roof 1 disposed above a vehicle body 4, the roof 1 being detachably connected to the vehicle body 4 via mounting bolts 2 on both sides. Inner folding plates 5 are welded to the top of both sides of the vehicle body 4, the inner folding plates 5 being located inside the mounting bolts 2, i.e., near the center of the vehicle body 4. One inner side of the inner folding plate 5 is bent upwards at 90°, forming a vertical support surface. A sealing strip 6 is fitted onto the upper part of this bent surface. The sealing strip 6 has an inverted U-shaped structure, with an anti-detachment protrusion 61 on its inner side. The anti-detachment protrusion 61 is integrally connected to the sealing strip 6, and the anti-detachment protrusion 61 has a certain upward inclination angle to increase the anti-detachment capability. Furthermore, the inner side of the sealing strip 6 is longer than the outer side, facilitating the sealing strip 6 to be secured onto the inner folding plate 5.

[0019] A sealing groove 7 is fixedly installed on the lower side of the roof 1 by welding, and its position corresponds to the sealing strip 6. A sealing rubber tube 8 is embedded in the sealing groove 7. When the roof 1 is installed in place, the top of the sealing strip 6 elastically presses against the sealing rubber tube 8, forcing the sealing rubber tube 8 to expand and deform to both sides, tightly fitting the inner wall of the sealing groove 7, forming the first dynamic sealing barrier, blocking the water seepage path of the bolt holes, and compensating for the assembly gap between the vehicle body 4 and the roof 1.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the installation structure has been further optimized: Sealed mounting structures are provided on both sides of the roof 1, including: live screw seats 9 welded on the body 4; The roof 1 is composed of a roof panel 101, side panels 102 on both sides, a seat panel 103, and a support plate 104. The side panels 102 are integrally connected to the roof panel 101. The right side of the seat panel 103 is welded to the inner side of the side panel 102. The lower part of the support plate 104 is welded to the upper side of the seat panel 103. The upper end of the support plate 104 is welded to the lower side of the roof panel 101 to form a stable support. Mounting screw holes 10 are provided on the base plate 103, and mounting holes 11 are provided at corresponding positions on the top cover plate 101; Mounting bolt 2 passes through mounting hole 11 and mounting screw hole 10, and is threaded into live screw seat 9; A waterproof cap 12 is installed on the top of the mounting hole 11 to form a second bolt hole seal; Meanwhile, an elastic washer 201 and a large washer 202 are fitted onto the stud of the mounting bolt 2. The large washer 202 prevents rainwater from seeping in, while the elastic washer 201 makes the mounting bolt 2 less prone to loosening, thus avoiding gaps caused by vibration during vehicle movement.

[0021] Drainage design: The two sides of the top cover plate 101 are bent downward and inclined at an angle of 5° to 15° to guide rainwater to flow to both sides; Drainage holes 13 are provided at the bottom of the side panel 102 to drain water in time and prevent rainwater from accumulating in the sealed area.

[0022] Brief description of working principle During installation: Align the roof 1 with the body 4 and tighten it with the mounting bolts 2 and the live bolt seat 9. The sealing strip 6 rises with the inner folding plate 5, squeezing the sealing rubber tube 8, causing it to expand and fill the mating groove, forming an elastic sealing interface.

[0023] Dynamic sealing: If vibration or deformation occurs during vehicle operation, the elasticity of the sealing strip 6 and the sealing rubber tube 8 can adaptively shift to maintain sealing pressure and prevent rainwater from seeping in through the holes of the mounting bolts 2.

[0024] Drainage mechanism: Rainwater flows along the inclined top cover plate 101 to both sides and is discharged through the drainage holes 13 to prevent water from seeping into the sealed area.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
