Description

[0002] In the prior art, a wind screen is arranged at the connection between two rail vehicles, and the main structure of the wind screen is formed by a flexible tarpaulin. The function of the wind screen is to form a connection channel between the two rail vehicles, so as to prevent wind, sand, rain and snow from entering the rail vehicles and ensure the free movement of passengers inside the rail vehicles.

[0003] In the related art, the wind screen is a flexible structure, and needs to meet the relative movement between the two rail vehicles, including stretching, compression, twisting, misalignment and the like. When the wind screen is used in a strong snow environment, the wind screen has structural defects, which are specifically as follows: when the rail vehicles run in a strong snow environment, a large amount of snow will gather at the folds of the tarpaulin at the top of the wind screen and freeze. After freezing, the flexibility of the tarpaulin disappears, and the tarpaulin no longer has the functions of stretching and compression. When the two rail vehicles move relative to each other, the tarpaulin of the wind screen will be torn, resulting in damage to the wind screen, leakage of snow water into the rail vehicles, and affecting the safety and comfort of the rail vehicles.

[0036] In some possible embodiments, as shown in Figure 7 The sliding support base 613 includes a bottom plate 6131 and a ball clamping plate 6132. The bottom plate 6131 is connected to the cover plate body 6121, and a cavity is formed between the bottom plate 6131 and the inner concave side of the boss cover part 6122. The boss cover part 6122 is provided with an avoiding opening communicating with the cavity. The ball clamping plate 6132 is located in the cavity and fixed to the bottom plate 6131.

The first insertion plate 61232 is inserted into the first insertion slot, and the first seat body 61231 penetrates through the longitudinal gap. The first vertical seat plate 6111 and the first transverse limiting plate 6112 are located on both sides of the first seat body 61231 in the thickness direction, thereby playing a limiting role.

[0041] When the first mounting base 611 and the first side cover plate are both arc-shaped, the first plug-in plate 61232 at the edge of the first side cover plate 612 can be gradually inserted into the first slot along one end of the first slot.

[0042] In some possible embodiments, the first fixing assembly 614 includes a first tightening block 6141 and a first screw rod 6142, the first plug-in seat 6123 is provided with a first embedding groove, one end of the first tightening block 6141 is embedded in the first embedding groove, the first screw rod 6142 is threadedly connected to the first tightening block 6141 and abuts against the first mounting base 611. By rotating the first screw rod 6142, the first tightening block 6141 can be effectively fixed on the first mounting base 611, such as abutting against the first vertical seat plate 6111 of the first mounting base 611.

[0043] In some possible embodiments, as shown in Figure 7 The second side cover plate assembly includes a second inner side cover plate 622 and a second outer side cover plate 623, the second inner side cover plate 622 is detachably connected to the second mounting base 621, the second outer side cover plate 623 is rotatably connected to the second inner side cover plate 622, and the second outer side cover plate 623 is supported on the sliding support base 613.

The two ends of the two torsion springs 6253 close to each other are limited on the fixed block 62521, and the two ends of the two torsion springs 6253 away from each other are limited on the corresponding shaft bodies 6251.

[0049] The elastic connecting assembly 625 has a damping and anti-vibration function. Before installing the elastic connecting assembly 625, the torsion of the torsion spring 6253 can be adjusted in advance to ensure that the upper cover plate is always pressed on the sliding support seat with a certain pressure, avoiding the second side cover plate from jumping and producing metal collision noise due to wind blowing or vehicle vibration.

The second mounting seat 621 has a second slot, and the second side inner cover plate 622 is provided with a second plug-in seat 6221 away from the second side outer cover plate 623. The second plug-in seat 6221 is inserted into the second slot, and the second fixing assembly 624 fixes the second plug-in seat 6221 to the second mounting seat 621.

[0052] The assembly structure of the second side inner cover plate 622 and the second socket 6221 is similar to the connection structure between the first side cover plate 612 and the first mounting seat 611. For example, the second mounting seat 621 comprises a second vertical seat plate and a second transverse limiting plate, the second vertical seat plate is provided with a second slot, the second transverse limiting plate is connected to the second vertical seat plate and has a second longitudinal gap with the second vertical seat plate, the second socket 6221 comprises a second seat body and a second plug plate vertically connected to the second seat body, the second plug plate is inserted into the second slot, the second seat body penetrates through the longitudinal gap, and the second vertical seat plate and the second transverse limiting plate are limited on both sides of the second seat body in the thickness direction.

[0053] In some possible embodiments, the second fixing assembly 624 comprises a second tightening block and a second screw rod, and the structure of the second fixing assembly 624 is the same as that of the first fixing assembly. The second socket 6221 is provided with a second embedding groove, one end of the second tightening block is embedded in the second embedding groove, and the second screw rod is threadedly connected to the second tightening block and abuts against the second mounting seat 621.

[0054] In some possible embodiments, the first cover plate assembly 610 and the second cover plate assembly 620 are both arched or curved in the middle, which can effectively prevent snow from falling onto the upper part of the tarpaulin windshield 602.

[0055] The windshield snow prevention device 60 is an arc-shaped cover that is convex on the top, which can shield the upper part of the tarpaulin windshield 602 and prevent foreign matters from entering the upper part of the tarpaulin windshield 602, and can also prevent water, sand and snow from accumulating. When there are foreign matters such as rain, sand and snow on the arc-shaped top of the windshield snow prevention device 60, the foreign matters can slide down along the arc-shaped slope of the windshield snow prevention device 60 smoothly due to the vibration of the vehicle. After the windshield snow prevention device 60 is installed, the upper part of the tarpaulin windshield 602 will not accumulate snow and freeze, thereby avoiding the problems that the tarpaulin windshield 602 is torn and damaged due to the fact that the tarpaulin is wrinkled and frozen by snow water when the tarpaulin windshield 602 is stretched, compressed and dislocated relative to each other during driving.

[0056] The embodiment of the present application also provides a rail vehicle, comprising a plurality of carriages 601 and the snow guard 60. The carriages 601 are arranged in sequence, and two adjacent carriages 601 are connected. The snow guard 60 is located between the two adjacent carriages 601, and the first mounting seat 611 and the second mounting seat 621 of the snow guard 60 are connected to the two adjacent carriages 601 respectively. The first mounting seat 611 and the second mounting seat 621 can be connected to the carriage 601 through fasteners. The snow guard 60 can be located on the top of the windbreak 602 and shield the windbreak 602, so that the snow and ice on the tarpaulin of the windbreak 602 cannot be accumulated, thereby avoiding the problems that the tarpaulin of the windbreak 602 is torn and damaged due to the tarpaulin wrinkles being frozen by snow water when the tarpaulin of the windbreak 602 is stretched, compressed and dislocated.
