[0002] Freight locomotives are used to transport goods. Freight locomotives have multiple groups of carriages. Every two adjacent carriages are connected through a windshield system. In the initial design of traditional freight windshields, in order to reduce costs and weight, the pedal area is often reduced on the pedal assembly of the windshield system. For example, Patent No.: CN201410202483.3 discloses a locomotive gangway, which specifically discloses the installation of a mounting frame on the carriage, and the mounting frame is used to connect the carriages on both sides. The mounting frame can also be used to support the pedal and connect the connecting rod assembly. The pedal on the mounting frame can completely cover the bottom of the windshield system to reduce the gap. When this solution is implemented, since the mounting frame adopts a surrounding frame structure, the supporting effect on the pedal is relatively small, and the supporting strength of the pedal is too small. When heavy goods pass through, the pedal is very likely to be concave, causing the edge of the pedal to be lifted and the pedal to fall from the mounting frame, posing a safety hazard.

DETAILED DESCRIPTION

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0023] like Figures 1 to 6 As shown, this embodiment provides a freight locomotive windshield, including a bellows assembly 10 and a pedal assembly 20 installed below the bellows assembly 10. Both sides of the bellows assembly 10 and the pedal assembly 20 are fixedly connected to the carriages on both sides to achieve a through connection between the two carriages.

[0024] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the folding shed assembly 10 includes a connecting frame 110 arranged around the entrance and exit of the carriage, a corrugated shed cloth 120 installed on the connecting frame 110 , a cloth clamping frame 130 installed between the shed cloths 120 , and a locking mechanism 140 installed in the connecting frame 110 .

[0025] like Figure 2 , Figure 5 and Figure 6As shown, the connection frame 110 is a U-shaped structure, and the connection frame 110 is fixed above the entrance and exit of the carriage. The connection frame 110 is made of a profile, and there are two connection frames 110, one of which is fixed on the end wall of the carriage, and the other connection frame 110 is fixed to the end of the awning cloth 120 parallel to the cloth clamping frame 130, and the two connection frames 110 are parallel to each other. The awning cloth 120 is made of a rubber elastic material. After the awning cloth 120 is bent, its root is inserted into the connection frame 110 and the cloth clamping frame 130. The cloth clamping frame 130 and the awning cloth 120 are arranged at intervals, and the cloth clamping frame 130 clamps and fixes two adjacent awning cloths 120. Under the clamping and fixing of the cloth clamping frame 130, the awning cloth 120 is installed between the end face frame and the connection frame 110 in a wave-shaped structure. Through the wavy shape of the awning cloth 120 and the elasticity of the awning cloth 120 itself, the folding awning assembly has the deformation performance of passing through irregular tracks such as bending or lifting. The locking mechanism 140 includes a locking tongue and a pin. The locking mechanism 140 is respectively arranged on two connecting frames 110, wherein a rotating locking tongue is installed on the connecting frame 110 close to the awning 120, and a positioning pin is installed on the other connecting frame 110. With the help of the positioning pin, the positions of the two connecting frames 110 will not be offset, thereby ensuring that the locking tongue can hook and clamp the connecting frame 110 after rotating relative to the connecting frame 110, thereby realizing a detachable connection between the two connecting frames 110 and completing the connection between the windshield system and the car body.

[0026] Preferably, a decorative shed 30 is also provided in the shed cloth 120, and the decorative shed 30 is fixed on the cloth clamping frame 130. The cross-section of the decorative shed 30 is a triangular structure. The decorative shed 30 is arranged above the pedal assembly 20. The decorative shed 30 is used to block the gap between the folding shed assembly 10 and the pedal assembly 20 to protect the normal use of the pedal assembly 20 and the folding shed assembly 10.

[0027] like Figures 1 to 4 As shown, the pedal assembly 20 includes a base plate 210, a mounting frame 220 fixed on the base plate 210, a pedal 230 fixed on the mounting frame 220, a ferry board 240 mounted on the pedal 230, and a connecting rod assembly 250 connected between the mounting frame 220 and the ferry board 240.

[0028] There are two base plates 210, which are arranged on both sides of the awning cloth 120. The base plates 210 are in a hinged plate-like structure. The mounting frame 220 includes a hanging plate 221 and a support plate 222 installed on the base plate 210. There are at least two hanging plates 221, and the hanging plates 221 are in a U-shaped plate-like structure. One side of the hanging plate 221 parallel to the two sides is fixed on the base plate 210, one side of the bottom of the hanging plate 221 is fixed on the end wall of the carriage, and the other side of the hanging plate 221 parallel to the two sides is arranged below the pedal 230. The support plate 222 is arranged close to the awning cloth 120. The support plate 222 is generally in a U-shaped structure, and the two parallel side ends of the support plate 222 are respectively fixed on the base plate 210 and the end of the car body, the hanging plate 221 and the support plate 222 are both fixed on the end of the car body, and under the connection of the mounting frame 220, the position of the base plate 210 relative to the end of the car body is fixed, and the bottom plate in the support plate 222 is arranged parallel to the base plate 210. Reinforcing plates are installed at the corners of the support plate 222, and the reinforcing plates are in a triangular structure, which are fixed to the side and bottom plates of the support plate 222. Under the action of the reinforcing plates, the supporting strength of the support plate 222 can be increased.

[0029] The pedal 230 is fixed on the side of the hanging plate 221 and the bottom of the support plate 222. The pedal 230 is a two-leaf hinge plate structure. The hinge on the pedal 230 is set between the hanging plate 221 and the support plate 222. The plate bodies on both sides of the hinge are respectively fixed on the hanging plate 221 and the support plate 222. When the base plate 210 and the mounting frame 220 need to be maintained, the corresponding plate body can be removed from the hanging plate 221 or the support plate 222, and folded to reveal the base plate 210 or the mounting frame 220 below. When the structure below the base plate 210 needs to be maintained, the connecting structure between the support plate 222 and the end of the car body can be disconnected. After the support plate 222 and the base plate 210 rotate around the hinge, the structure below the base plate 210 can be exposed, which is convenient for personnel to maintain the structure below. Two pedals 230 are provided corresponding to the base plate 210, and both sides of the ferry plate 240 are placed on the pedal 230. Wear plates are installed on the edges of the ferry plate 240. The wear plates are preferably made of wear-resistant materials such as PVE. The wear plates are arranged between the pedal 230 and the ferry plate 240. When the ferry plate 240 moves relative to the pedal 230, the friction loss between the ferry plate 240 and the pedal 230 can be reduced by compensating with the wear plates.

[0030] like Figure 3 and Figure 4As shown, the connecting rod assembly 250 includes a rotating base 251 and a connecting rod 252 hinged on the rotating base 251. The rotating base 251 is respectively mounted on the support plate 222 and the ferry 240. A hinged column is provided in the rotating base 251. The connecting rod 252 is cross-connected to form a scissor-like structure. Some end connection points and middle connection points of the connecting rod 252 are all provided on the rotating base 251. Under the connection of the connecting rod assembly 250, the position of the ferry 240 relative to the pedal 230 is fixed, which can prevent the ferry 240 from being separated from the pedal 230 and limit the range of movement of the pedal 230 relative to the ferry 240 to cooperate with the deformation of the folding canopy assembly 10 to ensure the curve ability of the windshield system through complex road conditions.

[0031] When the above-mentioned freight locomotive windshield is in use, the folding canopy assembly 10 is first fixed between the two carriages by using the connecting frame 110 and the locking mechanism 140, and the pedal assembly 20 is fixed on the carriage by using the hanging plate 221 and the supporting plate 222 in the mounting frame 220. When the vehicle needs to pass through special road conditions with bends and slopes during driving, the pedal 230 slides relative to the ferry plate 240, and the connecting rod assembly 250 and the canopy cloth 120 in the folding canopy assembly 10 are deformed synchronously to adapt to the needs of road conditions. When the windshield system needs to be inspected and maintained, the connection between the pedal 230 and the supporting plate 222 can be disconnected, and the lower connecting rod assembly 250 and the base plate 210 can be exposed after the pedal 230 is flipped over, and then the connection between the supporting plate 222 and the carriage can be disconnected, and the supporting plate 222 and the base plate 210 can be folded synchronously to form a maintenance opening. Since the support plate 222 and the hanging plate 221 form multi-point support for the pedal 230, it can prevent the pedal 230 from forming a hollow structure due to lack of support, thereby avoiding the phenomenon of warping and concavity, eliminating safety hazards.

[0032] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
