Description

Technical Field

[0001] The utility model belongs to the technical field of rail transportation equipment, and in particular relates to a side guard plate device for a through passage. Background Art

[0002] With the rapid development of my country's rail transit industry, the types of rail vehicles are gradually increasing. As an important component for connecting the vehicle body, the types of structures of the through-tunnel are also increasing to meet the requirements of diverse road conditions. Among them, the side guard plate is an important component of the internal channel of the through-tunnel, which provides side protection for the channel between the vehicle ends. In order to take into account the requirements of large-size vehicle-end distance and small curve path passing, the side guard plate mostly adopts a multi-piece structure, such as a five-piece structure.

[0003] like Figure 1 As shown, it is a schematic diagram of an existing five-piece side guard plate device, including an intermediate side plate 300, a first side plate 100, a second side plate 200, a first side plate 400 and a second side plate 500 linked by a connecting rod mechanism 600, the first side plate 100 and the second side plate 200 are installed on the through channel through a mounting seat 110, wear plates 800 are installed between the side plates, and the telescopic direction of the connecting rod mechanism 600 is 610. The connecting rod mechanism 600 generates opposite thrusts on the first side panel 400 and the second side panel 500 during the contraction process. Since one end of the first side panel 400 is in contact with the first side panel 100 only through the wear plate 800, and the second end of the first side panel 400 is assembled with the connecting rod mechanism 600 through the L-shaped mounting seat, the first side panel 400 will also rotate in the horizontal direction (in the direction of the arrow in the figure) under the action of the thrust. Similarly, during the extension and retraction process of the connecting rod mechanism 600, the first side panel 400 will also rotate in the opposite direction of the arrow in the figure. Therefore, the side guard plate has poor stability when moving and may collide with the adjacent guard plate or the connecting rod mechanism, thereby causing damage to the side guard plate and shortening the service life of the side guard plate.

[0004] In addition, due to the assembly method of the first side plate 400 and the L-shaped mounting seat of the connecting rod mechanism, the width of the first side plate 400 is relatively wide and must overlap with the rotation point of the connecting rod mechanism assembled therewith, resulting in a relatively heavy weight of the entire side guard plate.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0051] In the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0052] A side guard plate device for a through passage is a five-piece side guard plate device which can take into account the requirements of a large-sized vehicle end distance and a small curve path passing.

[0053] like Figure 2-17 As shown, the side guard plate device includes a connecting rod component 4, an intermediate guard plate component 3, two overlapping guard plates 2 and two side guard plates 1.

[0054] The middle guard plate component 3, the overlap guard plate component 2 and the side guard plate component 1 are linked by the connecting rod component 4. The overlap guard plate component 2 is located between the middle guard plate component 3 and the side guard plate component 1, and the overlap guard plate component 2 partially overlaps with the middle guard plate component 3 and the side guard plate component 1.

[0055] Specifically, the middle guard plate component 3, the overlapping guard plate component 2 and the side guard plate component 3 are arranged in the left and right directions in the figure. The middle guard plate component 3 forms the outermost layer of the side guard plate. The two overlapping guard plate components 2 are located on the inner side of the middle guard plate component 2, forming the second outer layer of the side guard plate. The two overlapping guard plate components 2 partially overlap with the left and right sides of the middle guard plate component 3, and part of the overlapping guard plate component 2 is exposed from the middle guard plate component 3. The two side guard plate components 1 are located on the inner side of the middle guard plate component 2, forming the third outer layer of the side guard plate. The two side guard plate components 1 partially overlap with the overlapping guard plate component 2, and part of the side guard plate component 1 is exposed from the overlapping guard plate component 2.

[0056] The connecting rod assembly 4 is located at the inner side of the side guard plate, and is rotatably connected with the middle guard plate assembly 3, the overlapping guard plate assembly 2 and the side guard plate assembly 1. The middle guard plate assembly 3, the overlapping guard plate assembly 2 and the side guard plate assembly 3 are assembled together through the connecting rod assembly 4.

[0057] like Figure 2-10As shown, the overlapping portion of the intermediate guard plate component 3 and the overlapping guard plate component 2 is provided with an intermediate guard plate wear-resistant layer 35 that slides with the overlapping guard plate component 2. The intermediate guard plate wear-resistant layer 35 can prevent the intermediate guard plate component 3 and the overlapping guard plate component 2 from wearing each other during the relative movement. Two intermediate guard plate wear-resistant layers 35 are provided on the intermediate guard plate component 3.

[0058] The intermediate guard plate component 3 includes an intermediate guard plate body 31, and the intermediate guard plate body 31 is specifically a profile. The two sides of the intermediate guard plate body 31 are bent inward to form an intermediate guard plate body bending surface 3121, and the inner side of the intermediate guard plate body 31 is provided with an intermediate guard plate wear-resistant layer mounting plate 3122, and the intermediate guard plate wear-resistant layer mounting plate 3122 is connected to the intermediate guard plate body bending surface 3121. The intermediate guard plate wear-resistant layer mounting plate 3122 is opposite to the intermediate guard plate body 31, and the intermediate guard plate wear-resistant layer mounting plate 3122 is connected to the inner side of the intermediate guard plate body 31. Generally, the intermediate guard plate body 31, the intermediate guard plate body bending surface 3121 and the intermediate guard plate wear-resistant layer mounting plate 3122 are an integrally formed profile, and the intermediate guard plate wear-resistant layer mounting plate 3122 forms a cavity with the intermediate guard plate body 31 and the intermediate guard plate wear-resistant layer mounting plate 3122, which can reduce the weight of the intermediate guard plate component 3.

[0059] Since the middle guard plate body 31 is generally wider, in order to facilitate processing, the middle guard plate body 31 includes a middle plate 311 and two side plates 312. The middle plate 311 includes an inward folding mounting portion 3111, and the inward folding mounting portion 3111 is assembled with the inner surface of the side plate 312. The outer surface of the middle plate 311 is connected to and flush with the outer surface of the side plate 312.

[0060] The middle guard plate wear-resistant layer mounting plate 3122 and the middle guard plate body bending surface 3121 are both located on the side plate 312 .

[0061] The intermediate guard plate assembly 3 includes a mounting seat 32 and an intermediate guard plate mounting shaft 321 assembled with the connecting rod assembly 4.

[0062] The mounting seat 32 is mounted on the middle guard plate body 31 , and the middle guard plate mounting shaft 321 is located on the mounting seat 32 . The middle guard plate mounting shaft 321 is vertically arranged with respect to the middle guard plate body 31 , and in particular, vertically arranged with respect to the middle plate 311 .

[0063] When the intermediate guard plate assembly 3 and the connecting rod assembly 4 are assembled, the sleeve is installed on the mounting shaft 321. After the mounting shaft 321 passes through the mounting hole on the connecting rod assembly 4, washers, compression springs, washers are installed on the mounting shaft 321 in sequence, and finally fasteners are installed. In some embodiments, the fasteners are slotted nuts and cotter pins, and the cotter pins need to pass through the slots of the slotted nuts and the holes at the ends of the mounting shaft 321.

[0064] The mounting seat 32 is located between two middle guard plate wear-resistant layers 35 .

[0065] Generally, a middle guard plate assembly 3 includes two sets of mounting seats 32 arranged in the up and down directions.

[0066] The middle guard plate component 3 also includes a middle guard plate skirt 33 , and two middle guard plate skirts 33 are located at the upper and lower ends of the middle guard plate body 31 .

[0067] The middle guard plate assembly 3 may further include a hanging plate 34 installed on the inner side of the middle guard plate body 31 .

[0068] In order to facilitate the assembly of the intermediate guard plate body 31 with other components, an intermediate guard plate body slide groove 313 is provided on the intermediate guard plate body 31 , and the intermediate guard plate body slide groove 313 runs through the upper and lower ends of the intermediate guard plate body 31 .

[0069] The middle plate 311 and the side plate 312 are both provided with intermediate guard plate body sliding grooves 313 .

[0070] The mounting seat 32 is fixed to the middle guard plate body slide groove 313 of the middle plate 311 and the side plate 312 through a fixing assembly; the inward folding mounting portion 3111 of the middle plate 311 is fixed to the middle guard plate body slide groove 313 of the side plate 312 through a fixing assembly; the middle guard plate skirt 33 is fixed to the middle guard plate body slide groove 313 of the middle plate 311 and the side plate 312 through a fixing assembly; the lifting plate 34 is fixed to the middle guard plate body slide groove 313 of the middle plate 311 through a fixing assembly.

[0071] The fixing assembly includes a screw, a washer and a slider located in the middle guard plate body slide groove 313, and the screw and the slider are threadedly matched. This method is convenient for assembly.

[0072] like Figure 11-14 As shown, a pin seat assembly is provided at the overlapping portion of the overlapping guard plate assembly 2 and the intermediate guard plate assembly 3, and the pin seat assembly includes a pin seat body 24 and a overlapping guard plate mounting shaft 241.

[0073] The pin seat body 24 is installed on the overlapping guard plate component 2 and has a protruding portion protruding from the overlapping guard plate component 2.

[0074] Specifically, the pin seat body 24 is in the shape of a long strip, one end of the pin seat body 24 is installed inside the overlapping guard plate component 2, overlapping with the overlapping guard plate component 2, and the pin seat body 24 installed in the overlapping guard plate component 2 can also be provided with a weight reduction hole to reduce the weight of the side guard plate. The other end of the pin seat body 24 protrudes from the overlapping guard plate component 2, does not overlap with the overlapping guard plate component 2, and the pin seat body 24 is parallel or substantially parallel to the overlapping guard plate component 2.

[0075] A wear plate 26 is provided on the protruding portion of the pin seat body 24, and the wear plate 26 and the middle guard plate form a sliding fit.

[0076] Specifically, the installation position of the pin seat body 24 corresponds to the installation seat 32 , so that the installation position of the wear plate 26 corresponds to the installation seat 32 , and the wear plate 26 and the installation seat 32 are slidably matched.

[0077] The protrusion has an end portion away from the overlapping guard plate assembly 2, and the wear plate 26 is located at the end portion so that the distance between the wear plate 26 and the intermediate guard plate wear-resistant layer 35 is as large as possible to ensure the stability of the overlapping guard plate assembly 2 during movement to the greatest extent.

[0078] The end of the protrusion is set at a certain angle to the protrusion, and the shape of the wear plate 26 is adapted to the shape of the end to increase the wear area of ​​the wear plate 26 and further ensure the stability of the movement process of the overlapping guard plate component 2.

[0079] In this embodiment, the pin seat body 24 is T-shaped, and the head of the T-shaped portion is the end of the protrusion, which is used to install the wear plate 26.

[0080] The wear plate 26 and the overlap guard plate installation shaft 241 are respectively located on both sides of the pin seat body 24.

[0081] The overlapping guard plate mounting axis 241 is vertically arranged with respect to the overlapping guard plate component 2, that is, the overlapping guard plate mounting axis 241 is parallel or approximately parallel with the intermediate guard plate mounting axis 321.

[0082] The overlapping guard plate assembly 2 includes an overlapping guard plate body 21 , and the overlapping guard plate installation shaft 241 is vertically arranged with respect to the overlapping guard plate body 21 .

[0083] The overlapping guard plate body 21 is a profile.

[0084] The overlapping guard plate body 21 has an overlapping guard plate body slide groove 211, and the pin seat body 24 is fixed on the overlapping guard plate body slide groove 211 through a fixing assembly.

[0085] The fixing assembly includes screws, washers and a slider located in the slide groove 211 of the overlapped guard plate body, and the screws are threadedly matched with the slider. This method is convenient for assembly.

[0086] The lap guard plate installation shaft 241 is assembled with the connecting rod assembly 4, and the lap guard plate installation shaft 241 is located between the wear plate 26 on the protruding portion and the lap guard plate assembly 2.

[0087] A wear plate 26 that slides with the intermediate guard plate assembly 3 is arranged on the protruding portion of the pin seat body 24 that protrudes from the overlapping guard plate assembly 2, and an intermediate guard plate wear-resistant layer 35 that slides with the overlapping guard plate assembly 2 is arranged at the overlapping portion where the intermediate guard plate assembly 3 and the overlapping guard plate assembly 2 are overlapped. The overlapping guard plate mounting shaft 241 assembled with the connecting rod assembly 4 is located between the wear plate 26 on the protruding portion and the overlapping guard plate assembly 2. Therefore, during the contraction or stretching process of the side guard plate, since there are wear parts on both sides of the overlapping guard plate mounting shaft 241 that slide with the intermediate guard plate assembly 3, the force acting on the overlapping guard plate mounting shaft 241 will not cause the overlapping guard plate assembly 2 to rotate horizontally, which can avoid the overlapping guard plate assembly 2 from colliding with other components (especially the connecting rod assembly and the intermediate guard plate assembly 3), avoid damage to the side guard plate, and ensure the service life of the side guard plate.

[0088] In addition, this embodiment adopts a flat pin body 24 to set a pin and a connecting rod mechanism perpendicular to it, which has a strength greater than Figure 1 The L-type mount shown has a longer life.

[0089] The axis of the overlapping guard plate installation shaft 241 does not intersect with the overlapping guard plate body 21. On the one hand, the overlapping guard plate installation shaft 241 is closer to the wear plate 26, so that the deflection force generated by the contraction or stretching of the connecting rod assembly 4 can be applied to the wear plate 26 as soon as possible, thereby preventing the overlapping guard plate assembly 2 from rotating horizontally as soon as possible; on the other hand, the width of the overlapping guard plate assembly does not need to cover the overlapping guard plate installation shaft 241, and the width of the overlapping guard plate assembly can be reduced to a certain extent, which is beneficial to the weight reduction of the side guard plate.

[0090] The overlapping portion of the overlapping guard plate component 2 and the edge guard plate component 1 is provided with an overlapping guard plate wear-resistant layer 25 which is slidably matched with the edge guard plate component 1.

[0091] The end of the overlapping portion of the overlapping guard plate body 21 and the edge guard plate 1 is bent inward to form a bending surface 212 of the overlapping guard plate body. The inner side of the overlapping guard plate body 21 is provided with an overlapping guard plate wear-resistant layer mounting plate 213, and the overlapping guard plate wear-resistant layer mounting plate 213 is connected to the bending surface 212 of the overlapping guard plate body.

[0092] The overlapping guard plate wear-resistant layer installation plate 213 is opposite to the overlapping guard plate body 21, and the overlapping guard plate wear-resistant layer installation plate 213 is connected to the inner side of the overlapping guard plate body 21. Generally, the overlapping guard plate body 21, the overlapping guard plate wear-resistant layer installation plate 213 and the overlapping guard plate body bending surface 212 are integrally formed profiles, and the overlapping guard plate body 21, the overlapping guard plate wear-resistant layer installation plate 213 and the overlapping guard plate body bending surface 212 form a cavity, which can reduce the weight of the overlapping guard plate component 2.

[0093] The overlapping guard plate assembly 2 further includes an overlapping guard plate upper skirt 22 and an overlapping guard plate lower skirt 23, which are respectively mounted at the upper and lower ends of the overlapping guard plate body 21.

[0094] The overlapping guard plate body slide groove 211 passes through the upper and lower ends of the overlapping guard plate body 21, and the overlapping guard plate upper skirt 22 and the overlapping guard plate lower skirt 23 are fixed on the overlapping guard plate body slide groove 211 through a fixing assembly.

[0095] like Figure 3-7 As shown in 15-17, the edge guard plate assembly 1 includes a connecting rod assembly assembly seat 18, and the connecting rod assembly assembly seat 18 is assembled with the connecting rod assembly 4.
