Description

Technical Field

[0001] The present invention belongs to the technical field of rail transit equipment, and particularly relates to an outer protection screen device for a gangway and a gangway. Background Art

[0002] A gangway is an internal passage for passengers to freely walk from one carriage of a vehicle body to another carriage, making passengers feel safe and comfortable. There is a certain gap between the bellows body and the station platform, and it is possible that drivers, crew members, or children accidentally fall through the gap, posing a safety hazard to passengers. Therefore, a protective barrier is installed outside the vehicle body gangway.

[0003] Currently, most of the protective barriers used in gangways only fix two plate-shaped side walls on both sides of the gangway by using connecting rods or mounting seats for prevention. For example, the application number is "CN201720966716.6", and the name is "Urban rail vehicle gangway with outer side wall device". However, the plate-shaped side walls need to be separately provided with connecting bodies to be fixed to the vehicle body, and due to the fixed shape of the plate-shaped side walls, the side walls cannot meet the safety protection requirements when the gangway of the vehicle is in various states such as expansion or contraction. Summary of the Invention

[0004] The present invention provides an outer protection screen device for a gangway and a gangway, which solves the technical problem that the existing plate-shaped outer side walls cannot meet the safety protection requirements when the vehicle gangway is in various states such as expansion or contraction.

[0005] To achieve the above technical purpose, the present invention is implemented by the following technical solutions:

[0006] The present invention provides an outer protection screen device for a gangway, including:

[0007] Two groups of frames, which are configured to be connected to the vehicle body;

[0008] A folding protective screen, which includes two groups of side frames, several groups of outer fabric frames, several groups of inner fabric frames, and fabrics; the two groups of side frames are respectively connected to the two groups of frames; several groups of outer fabric frames are located between the two groups of side frames; the inner fabric frames are arranged at intervals with the outer fabric frames, and the fabrics are used to connect adjacent outer fabric frames and inner fabric frames;

[0009] An installation part, which is arranged on the frame, and the installation part is configured to detachably install the frame on the vehicle body.

[0010] In some embodiments of the present application, the installation part includes:

[0011] Several first installation parts, including hanging holes opened on the frame;

[0012] A plurality of second mounting parts, including mounting holes and fasteners provided on the frame;

[0013] The second mounting portion is located below the first mounting portion.

[0014] The installation method of hanging first and then fastening is adopted, which is simple to operate, greatly reduces the installation time and improves the use efficiency.

[0015] In some embodiments of the present application, the hanging hole is a long strip through hole with arc-shaped upper and lower ends, and the width of the upper end of the hanging hole is smaller than the width of the lower end of the hanging hole. The long strip through hole with narrow upper end and wide lower end can achieve both hanging and limiting, preventing the outer protective screen device from moving back and forth, resulting in a decrease in the prevention effect.

[0016] In some embodiments of the present application, a first card slot is provided on the outer fabric frame, and a second card slot is provided on the inner fabric frame. The first card slot and the second card slot are arranged opposite to each other, and the inner walls of the first card slot and the second card slot are serrated. The fabric card is arranged in the adjacent first card slot of the outer fabric frame and the second card slot of the inner fabric frame.

[0017] The fabric card is set in the first card slot of the outer fabric frame and the second card slot of the inner fabric frame, which can realize the relative position adjustment between the adjacent outer fabric frame and the inner fabric frame to realize the expansion or contraction of the foldable protective screen, so that the size of the outer protective screen device matches the telescopic state of the through channel. The serrated card slot has a large friction force and a good clamping effect on the fabric, making the outer protective screen device highly reliable.

[0018] In some embodiments of the present application, the frame and the top of the foldable protective screen both have an arc portion. The arrangement of the arc portion is adapted to the corner of the bellows of the through passage, so that the protection range of the external protective screen device includes the top of the through passage, which is safer and more aesthetically pleasing.

[0019] In some embodiments of the present application, the frame is further provided with a tightening structure for folding the outer screen device. The outer screen device can be tightened by the tightening structure, so that train marshaling operations can be performed with only one end of the frame of the outer screen device removed.

[0020] In some embodiments of the present application, the outer screen device further comprises a connecting rod mechanism connected to the inner fabric frame. The connecting rod mechanism can evenly spread the fabric so that the protective effect of each part of the outer screen device is the same.

[0021] In some embodiments of the present application, the link mechanism includes a plurality of links, which are hinged to each other. A transition seat is installed on the inner fabric frame, and a hinge shaft is provided on the transition seat. The link is hinged to the hinge shaft. When the ends of the plurality of links are hinged to each other and the outer protection screen device is tightened or unfolded, and the link mechanism is tightened or unfolded driven by the frame, the fabric can be evenly tensioned and relaxed. In some embodiments of the present application, a mounting seat is provided on the frame, and an end seat is provided on the link mechanism. The end seat and the mounting seat are hinged by a pin shaft. The mounting seat facilitates the connection of the link mechanism to the frame, making the installation firm and convenient.

[0022] The present invention also provides a gangway, which includes the above-mentioned outer protection screen device for the gangway, and the outer protection screen device for the gangway is located outside the gangway.

[0057] As Figures 1 to 9 shown, this embodiment provides an outer screen device for a gangway, including a frame body 100, a folding screen 200 and a mounting portion 300. As Figures 10 to 13 shown, after the outer screen device 1 is installed on the side of the gangway, a safer and more reliable gangway is formed.

[0058] Next, the outer screen device for the gangway will be described first:

[0059] The frame body 100 includes two groups, and the frame body 100 is used for connecting the outer screen device 1 to the vehicle body.

[0060] The folding screen 200 is installed between the two groups of frame bodies 100. The folding screen 200 includes two groups of side frames 210, several groups of inner fabric frames 230, several groups of outer fabric frames 220 and a fabric 240. The two groups of side frames 210 are respectively connected to the frame body 100. The outer fabric frames 220 and the inner fabric frames 230 are both located between the two groups of side frames 210. The inner fabric frames 230 and the outer fabric frames 220 are arranged at intervals. The fabric 240 is used for connecting adjacent outer fabric frames 220 and inner fabric frames 230.

[0061] The mounting portion 300 is provided on the frame body 100, and the mounting portion 300 is used for detachably mounting the outer screen device 1 on the vehicle body.

[0062] Specifically, the frame 100 is a long rod-shaped structure adapted to the height of the gangway and having a certain width.

[0063] The side frames 210, the inner fabric frames 230 and the outer fabric frames 220 of the foldable protective screen 200 are also long rod-shaped structures with a certain width, and their sizes are adapted to the frame 100. The two outermost outer fabric frames 220 are connected to the inner sides of the side frames 210; the fabric 240 of the foldable protective screen 200 is made of a special material tarpaulin, such as CSM, Silicone and other materials. The tarpaulin of the above materials has the advantages of high strength, high elongation rate, scratch resistance, fire resistance, etc., and is suitable for use on both sides of the gangway, making the use safety of the outer protective screen device 1 high and the service life long; the tarpaulin includes several pieces, and the several pieces of tarpaulin are sewn together. The unfolded width of the foldable protective screen 200 is greater than or equal to the length of the gangway; the outer fabric frames 220 and the inner fabric frames 230 are placed at intervals, and the sewn tarpaulin is connected to the inner fabric frames 230 and the outer fabric frames 220.

[0064] During use, first, the two groups of frames 100 are respectively installed on two car bodies on both sides of the gangway through the installation part 300, located on both sides of the gangway. The frame 100 can drive the foldable protective screen 200 to stretch or compress according to the state of the gangway being pulled or squeezed by the car body, so as to achieve a better protection effect of the outer protective screen device 1.

[0065] Refer to Figures 2 to 4 , the installation part 300 includes several first installation parts 310 and several second installation parts 320. The second installation parts 320 are located below the first installation parts 310, where:

[0066] The first installation part 310 is used to hang the outer protective screen device 1 on the car body. The several first installation parts 310 include hanging holes 311 opened on the frame 100.

[0067] The hanging holes 311 are symmetrically arranged on the two groups of frames 100. The several hanging holes 311 on each group of frames 100 are evenly arranged, and the first installation parts 310 on the two groups of frames 100 are symmetrically arranged one by one. Hanging parts 312 are arranged at the positions corresponding to the hanging holes 311 on the car body. After the hanging parts 312 pass through the hanging holes 311, the frame 100 and the foldable protective screen 200 can be hung on the car body, thus completing the hanging of the outer protective screen device 1 on the car body.

[0068] The second installation part 320 is used to fix the outer protective screen device 1 on the car body. The several second installation parts 320 include installation holes 321 opened on the frame 100 and fasteners 322.

[0069] In this embodiment, a plurality of mounting holes 321 on each frame body 100 are evenly arranged, and the mounting holes 321 on two groups of frame bodies 100 are symmetrically arranged one by one. The fastener 322 passes through the mounting holes 321 to mount the frame body 100 on the vehicle body, thereby completing the fixation of the outer protection screen device 1 on the vehicle body.

[0070] The fastener 322 in this embodiment is a bolt.

[0071] During use, the staff first inserts the hanging member 312 into the hanging hole 311. Under the action of gravity, the outer protection screen device 1 is hung on the vehicle body. Then, the fastener 322 is used to pass through the mounting hole 321 to fix the frame body 100 and the vehicle body, so as to assemble the outer protection screen device 1 on the vehicle body outside the through passage, thereby ensuring that the outer protection screen device 1 is always fixed outside the through passage during use; the installation method of hanging first and then fastening is simple in operation, time-saving and labor-saving, and has high installation efficiency.

[0072] Refer to Figure 4 , the hanging hole 311 is a long strip-shaped through hole with circular arcs at both the upper end and the lower end.

[0073] The specific shape of the long strip-shaped through hole is: the upper end part is an arc, the lower end part is an arc, and the two are connected by a rectangle, and the arc at the upper end of the hanging hole 311 is smaller than the arc at the lower end of the hanging hole 311.

[0074] The long strip-shaped through hole increases the operation space for hanging the outer protection screen device 1, compensates for the error between the frame body 100 and the vehicle body, and the arc at the upper end of the hanging hole 311 is smaller than the arc at the lower end of the hanging hole 311. Without the need for the staff to align carefully, the hanging member 312 can be directly inserted into the hanging hole 311 from the end with the larger arc, and the end with the smaller arc can limit the hanging member 312 to prevent the outer protection screen device 1 from shaking back and forth in the horizontal direction, affecting the safety of the installation of the outer protection screen device 1.

[0075] Refer to Figure 4 , in this embodiment, the hanging member 312 on the vehicle body includes a hanging rod 3121 and a hanging sleeve 3122. One end of the hanging rod 3121 is arranged on the vehicle body, and the other end of the hanging rod 3121 is externally sleeved with a hanging sleeve 3122. The diameter of the hanging sleeve 3122 is smaller than the lower diameter of the long strip-shaped through hole, and the diameter of the hanging sleeve 3122 is larger than the upper diameter of the long strip-shaped through hole.

[0076] Specifically, the hanging rod 3121 is a cylindrical small rod, and a threaded hole is provided at the corresponding position on the vehicle body. One end of the hanging rod 3121 is fixed in the threaded hole so that the hanging rod 3121 is perpendicular to the vehicle body; the hanging sleeve 3122 is an annular sleeve, and the hanging sleeve 3122 is fixed outside the other end of the hanging rod 3121; the diameter of the hanging sleeve 3122 is smaller than the diameter of the lower end of the hanging hole 311, and the diameter of the hanging sleeve 3122 is larger than the diameter of the upper end of the hanging hole 311.

[0077] When installing the outer protection screen device 1, the hanging holes 311 at the upper part of the frame body 100 correspond to the hanging sleeves 3122. Since the diameter of the hanging sleeve 3122 is smaller than the diameter of the lower end of the hanging hole 311, the hanging sleeve 3122 can easily pass through the lower end of the hanging hole 311. Then, the frame body 100 moves downward, and the hanging sleeve 3122 is snapped into the upper end of the hanging hole 311. Since the diameter of the hanging sleeve 3122 is larger than the diameter of the upper end of the hanging hole 311, it can prevent the hanging hole 311 from disengaging from the hanging sleeve 3122, realizing the limit of the outer protection screen device 1. At this time, one side of the outer protection screen device 1 is hung on the vehicle body; then, use the fastener 322 to pass through the mounting hole 321 on the frame body 100 and tighten it to completely fix one side of the outer protection screen device 1; similarly operate to fix the other side of the outer protection screen device 1, and at this time, the outer protection screen device 1 is completely fixed on the vehicle body.

[0078] When the outer protection screen device 1 needs to be disassembled, unscrew and remove the fastener 322 at the mounting hole 321, and the operator lifts this side of the frame body 100 upward to realize the separation of one side of the outer protection screen device 1 from the vehicle body; similarly operate to realize the separation of the other side of the frame body 100 of the outer protection screen device 1 from the vehicle body, and at this time, the outer protection screen device 1 is completely separated from the vehicle body.

[0079] Refer to Figure 5 、 Figure 6 On the outer fabric frame 220, there is a first card slot 221, and on the inner fabric frame 230, there is a second card slot 231. The first card slot 221 and the second card slot 231 are arranged oppositely. After the fabric 240 is sewn and formed, the seams are sequentially clamped in the adjacent first card slot 221 and second card slot 231.

[0080] The inner walls of both the first card slot 221 and the second card slot 231 are serrated. The serrated inner walls of the card slots increase the friction between the fabric 240 and the inner walls of the card slots, with a large clamping strength, making it difficult for the fabric 240 to disengage from the card slots, and increasing the stability and safety during the use of the outer protection screen device 1.

[0081] The tops of the frame body 100, the frame 210, the outer fabric frame 220, and the inner fabric frame 230 all have arc-shaped parts.

[0082] Since the corners of the bellows 4 of the gangway are all smooth rounded corners, the tops of the frame 210, the outer fabric frame 220, and the inner fabric frame 230 are all bent in one direction to form arc-shaped parts, which are adapted to the corners of the bellows 4 of the gangway, thereby increasing the safety prevention range of the outer protection screen device 1, and having higher safety and aesthetics.

[0083] The frame body 100 is also provided with a tightening structure for making the outer protection screen device 1 in a folded state. Refer to Figure 1 、 Figure 2, in this embodiment, the tightening structure is a tightening ring 110 provided on the frame 100, and the tightening ring 110 is a through hole opened at the bottom end of the frame 100.

[0084] When the train needs to be re - grouped, after one side of the outer protection screen device 1 is disassembled and separated from the vehicle body, a tightening belt is passed through the two tightening rings 110 on both sides, and then the tightening belt is tightened and tied to the tightening ring 110 to implement the tightening procedure of the outer protection screen device 1, so that the outer protection screen device 1 does not need to be removed when the train is re - grouped; if the train does not need to be re - grouped, the tightening procedure is not required.

[0085] In order to make the folding screen 200 unfold or contract evenly during the movement of the vehicle body, the outer protection screen device 1 further includes a link mechanism 400.

[0086] Refer to Figure 7 , in this embodiment, there are two groups of link mechanisms 400. Both ends of the two groups of link mechanisms 400 are arranged on the frame 100. One group of link mechanisms 400 is arranged near the bottom end of the frame 100, and the other group of link mechanisms 400 is arranged near the top end of the frame 100.

[0087] The link mechanism 400 is configured to support the inner fabric frame 230 and is fixed to the frame 100 through the mounting seat 430, so that the folding screen 200 unfolds evenly. The link mechanism 400 prevents the folding screen 200 from over - unfolding and causing tearing of the folding screen 200, resulting in damage to the outer protection screen device 1. The two groups of link mechanisms 400 are respectively arranged near the top and bottom ends of the frame 100, which helps to make the upper and lower parts of the frame 100 stress evenly and ensure the consistency of the upper and lower structures of the frame 100.

[0088] Refer to Figure 8 , Figure 9 , the link mechanism 400 includes a number of links 410. The ends of the links 410 are hinged to each other through pins to form a number of diamond - shaped telescopic structures. Two parallel links in the telescopic structure are also hinged with an auxiliary link 420 through pins in the middle.

[0089] The middle part of the auxiliary connecting rod 420 and the connection part of the two sets of telescopic structures are provided with hinge holes 490. At the position corresponding to the hinge holes 490 on the inner fabric frame 230, a transition seat 450 is installed. The transition seat 450 is fixedly installed on the inner fabric frame 230 by rivets. A hinge shaft 451 is installed on the transition seat 450. The connection part of the auxiliary connecting rod 420 and the two sets of telescopic structures is hinged on the hinge shaft 451 through the hinge holes 490, and then a slotted nut is installed for locking and limiting. A nylon sleeve 460 is provided between the connecting rod 410 and the hinge shaft 451, and a nylon gasket 470 and a channel washer 480 are provided between the connecting rod 410 and the slotted nut. If the metal parts directly contact during the relative rotation process, mutual damage problems will occur. The nylon sleeve 460 and the nylon gasket 470 can prevent the direct contact between the metal parts, and the channel washer 480 can prevent the relative rotation between the metal parts, which can well solve the problem of mutual damage.

[0090] Mounting seats 430 are fixedly connected to the positions on the frame body 100 corresponding to both ends of the connecting rod mechanism 400. End seats 440 are provided at the ends of the connecting rod mechanism 400, and the end seats 440 are hinged to the mounting seats 430 through pin shafts.

[0091] Fixing the connecting rod mechanism 400 to the folding protective screen 200 through the transition seat 450 and the hinge shaft 451 can enable the connecting rod mechanism 400 to support the folding protective screen 200 more evenly and make the appearance of the outer protective screen device 1 beautiful.

[0092] The outer protective screen device for the gangway provided by the present invention uses a folding protective screen to change the size according to the movement state of the vehicle body, thereby forming a more effective safety barrier.

[0093] Next, the gangway will be described again:

[0094] The gangway includes the above-mentioned outer protective screen device for the gangway, and the outer protective screen device for the gangway is located on the outside of the gangway.

[0095] Refer to Figures 10 to 13 , the gangway further includes a ferry plate 2, a pedal 3, a ferry plate connecting rod 6 and a folding roof 4. One side of the outer protective screen device 1 is connected to the end of the vehicle body, and the other side is connected to the end of another vehicle body. Both sides of the folding roof 4 are connected to the ends of two adjacent vehicle bodies through mounting frames 5. The mounting frames 5 can be set to have the function of quick locking and unlocking according to requirements, or can be set without this function.

[0096] Both ends of the crossover link 6 are respectively connected to the bottom of the mounting frame 5. A wear member 7 is provided on the tread plate 3. The tread plate 3 includes a tread body 31 and a tread flap 32. After the tread body 31 is connected to the floor surface at the end of the vehicle body, it is slidably contacted with the crossover link 6 through the wear member 7 provided on the tread flap 32. A wear member 9 is also provided at the bottom of the crossover plate 2. The crossover plate 2 is connected to the crossover link 6 through a retaining pin 8. The bottom of the crossover plate 2 is slidably contacted with the upper surface of the tread flap 32 through the wear member 9 provided at the bottom edge.
