Description

Technical Field:

[0001] The present invention belongs to the technical field of rail transit equipment, and particularly relates to a gangway device with an occlusion mechanism, which improves the service performance of the gangway by improving the structure of the wall panel assembly. Background Art:

[0002] With the rapid development of the rail transit industry, the types of rail vehicles are gradually increasing. As an important component for connecting car bodies, in order to meet the requirements of diverse road conditions, the types of gangway structures are also constantly increasing. The wall panel assembly, as an important part of the internal passage of the gangway, needs to protect the side of the internal passage and support the relative movement between vehicles, including pitching, rolling or rotational movement, or horizontal or vertical displacement. At the same time, the wall panel assembly also needs to enhance the transition effect visually. In order to balance the requirements of visual aesthetics and passing through small curved paths, the wall panel assemblies of the gangways in the prior art all adopt a single-piece structure, which is pre-assembled and installed as a unit. When the two vehicles are decoupled, the entire wall panel assembly must be disassembled. Due to its own weight, not only a considerable amount of manpower is required, but also complex tools and bracket structures are needed to close the wall panel assembly during the coupling process, reducing the service life. Therefore, it is necessary to research and develop a gangway device with an occlusion mechanism to reduce the weight of the wall panel assembly, ease the decoupling difficulty, and achieve safety protection. Summary of the Invention:

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art, research and develop a gangway device with an occlusion mechanism, reduce the labor intensity, and solve the problem of low service life of the single-piece wall panel assembly.

[0004] To achieve the above purpose, the main structure of the gangway device with an occlusion mechanism involved in the present invention includes a diaphragm assembly, a roof assembly arranged on the inner top surface thereof, a floor assembly arranged on the bottom surface, wall panel assemblies arranged on both sides, and occlusion mechanisms arranged at both ends of the wall panel assemblies;

[0005] The main structure of the wall panel assembly includes a wall panel component, fixators arranged on both sides thereof, and a support component arranged on the bottom; wherein:

[0006] The main structure of the wall panel component includes a center plate with a flexible arc structure, a frame arranged at the long side thereof, a cover plate arranged at the short side thereof, and a plurality of cables arranged on the back; a plurality of locking mechanisms are arranged on the front of one frame, a guide plate is arranged on the back, and a plurality of fastening elements, hooks and fastening holes are arranged on the back of the other frame; or a plurality of locking mechanisms are arranged on the fronts of both frames, and guide plates are arranged on the backs;

[0007] The main structure of the locking mechanism includes a lock cover and a lock core arranged therein;

[0008] Moreover, the lock cover is installed on the frame through a lock nut, the lock core is installed in the lock cover through a rubber ring, a lock washer is arranged between the lock nut and the frame, and the inner end face of the lock cover is an inclined plane;

[0009] The main structure of the retainer includes short cover plates arranged at both ends of the retainer base; several fixing sleeves arranged in the concave surface of the retainer base, a mandrel passing through the fixing sleeve, and a connecting element arranged on the mandrel; several mounting seats and torsion springs arranged on the support panel of the retainer base;

[0010] Specifically, the connecting element is composed of several guide seats, positioning seats and positioning springs. A lock seat is also arranged on the guide seat. The positioning spring is arranged between the positioning sleeve and the positioning seat. An adjusting mechanism is arranged on at least one positioning spring. The guide seat and the positioning seat are connected by a connecting bar. Abrasion strips and a positioning plate or a center pin are arranged on the connecting bar. A guide groove is opened on the positioning plate;

[0011] Moreover, the support panel and the mounting seat are connected through a hinge seat. The mounting seat with at least two stoppers (the first stopper and the second stopper) is connected to the torsion spring. The torsion spring is arranged between the mounting seat and the hinge seat;

[0012] Furthermore, the adjusting mechanism is composed of two pluggable connecting adjusting sleeves;

[0013] The main structure of the support assembly includes a seat plate and a V-shaped support plate arranged thereon;

[0014] The main structure of the shielding mechanism includes a fixing plate and gussets arranged at both ends thereof, a baffle and a brush arranged obliquely on the back, and an adhesive tape and a light strip arranged on the front; the inclination directions of the baffle and the brush are different and have a tendency to intersect.

[0015] When the number of the folding roofs involved in the present invention is 2, a partition assembly can be added between the two.

[0016] The retainer of the present invention rotates around the rotation axis formed by two mounting seats, and the torsion spring applies a torque to the retainer so as to pull the wall panel assembly towards the direction of the vehicle connected to the retainer, and the convex surface of the retainer rotates around the rotation axis during the movement.

[0017] The connecting element rotates around the mandrel and rotatably connects the wall panel assembly to the retainer. At the same time, the guide seat can move on the mandrel, so that the connecting element and the wall panel assembly connected thereto move relative to the retainer along the mandrel in the height direction.

[0018] By moving the guide seat on the mandrel, the wall panel assembly translates relative to the fixture to compensate for the vertical deviation between two vehicles, i.e., the height difference that occurs in the direction of the axis of rotation, including the uneven wear of the wheels of the two vehicles or the vertical deviation that occurs when the spring states of the main suspension or secondary suspension of the vehicle are different.

[0019] When the wall panel assembly is displaced, the lower edge and the upper edge move parallelly, and the deformation is almost evenly distributed on the cover plate and the short cover plate.

[0020] When the cover plate and the short cover plate collide with the top plate assembly or the floor assembly, deformation always occurs. The extension amount of the cover plate and the short cover plate parallel to the height direction is equivalent to 5% to 20% of the dimension of the fixture in the same direction. After one side of the wall panel assembly is opened, the support assembly plays a supporting role to avoid damage to the cover plate at the lower edge.

[0021] One end of the positioning spring is supported on the fixed sleeve, and the other end is supported on the guide seat. A prestress is applied between the two through the adjusting mechanism so as to position the wall panel assembly along the mandrel or restore the wall panel assembly to the initial position after the vertical displacement ends. The acting directions of the two positioning springs are opposite, and reset can be achieved regardless of whether the vertical displacement is a positive displacement or a negative displacement (upward displacement or downward displacement).

[0022] When the vehicle turns, the cable and the torsion spring cooperate together to make the wall panel assembly return to the starting position immediately after the turn is completed. During this period, the wall panel assembly is stretched on the outer side of the turn and compressed on the inner side of the turn.

[0023] Compared with the prior art, the present invention is used for the transition area between two interconnected vehicles, and at least includes a folding shed assembly, a roof panel assembly arranged on the inner top surface thereof, a floor panel assembly arranged on the bottom surface, side wall panel assemblies arranged on both sides, and shielding mechanisms arranged at both ends of the wall panel assemblies. The wall panel assembly is composed of a wall panel component and fixators arranged on both sides thereof. The fixator is connected to at least one fixed seat through a hinge seat so as to rotate around a rotation axis formed by the mounting seat. The wall panel components are respectively hingedly connected to the two fixators so as to rotate around a core shaft and slide axially. The fixator and the cover plate with elastic deformability arranged at the end of the wall panel component are made of rubber, and adapt to the vertical offset generated between the two vehicles through deformation, and contact the roof panel assembly and the floor panel assembly to protect the fixator and the wall panel component from damage. A support mechanism is further arranged on the lower side of the wall panel component. When opened, it supports the wall panel component to avoid damage to the cover plate here. The arc of the wall panel component is achieved by the stretching of a cable, and the arc can ensure that the wall panel component protrudes towards the center of the aisle when bent. During the contraction or stretching process of the wall panel assembly, the force acting on the wall panel component will not cause continuous contact or continuous relative movement between the wall panel component and other components, resulting in wear. The shielding mechanism is fixed on the vehicle and is located outside the fixator to shield the gap between the vehicle and the fixator. In addition, the wall panel component and the cover plate have the characteristic of self-recovery after bending and can fully adapt to the increase in the outer distance and the decrease in the inner distance and the change in vertical offset when the vehicle passes through a curve.

[0050] Further, the main structure of the adjusting mechanism 5211 is as shown in Figure 12 the figure, and it is composed of two adjusting sleeves, the lower part of the upper adjusting sleeve 5231 with an oval slot 5230 is inserted into the lower adjusting sleeve 5233 with a threaded hole 5232, the oval slot 5230 and the threaded hole 5232 are connected by a screw 5234, and mounting holes 5235 are formed in both the upper adjusting sleeve 5231 and the lower adjusting sleeve 5233;

[0051] The main structure of the support assembly 53 is as shown in Figure 5 the figure, and it includes a seat plate 530, a support plate 531 and a fixing hole 532; a V-shaped support plate 531 is arranged on the seat plate 530, the support plate 531 is arranged on the seat plate 530 through a fastener 100, a fixing hole 532 is formed at the top thereof, and the bottom of the wall plate assembly 51 is connected to the fixing hole 532 of the support assembly 53 through a fastener 100;

[0052] The main structure of the shielding mechanism 6 is as Figures 13 - 14 shown, including a fixing plate 61, angle plates 62, a baffle 63, a brush 64, a tape 65, and a light strip 66; angle plates 62 are provided at both ends of the fixing plate 61, the baffle 63 and the brush 64 are obliquely arranged on the back, and the tape 65 and the light strip 66 are provided on the front; the angle plates 62 are arranged on the fixing plate 61 through fasteners 100, and the baffle 63 and the brush 64 have different inclination directions and tend to intersect.

[0053] The weights of the wall panel assembly 51 and the fixator 52 involved in this embodiment are both less than 20 kg, and they are both assembled and processed separately, meeting the requirements of one-time hoisting or assembly, and one person can complete the operation (the prior art stipulates that the entire pre-assembled wall panel composition must be hoisted or assembled at one time. The total weight of the traditional pre-assembled wall panel composition is large and does not meet the requirement of one-person operation specified by the specification);

[0054] The center plate 510 is a thermosetting plate made of synthetic resin, embedded with glass fibers, and has the characteristics of high strength and high fire resistance and flame retardancy. The connection with the frame 511 is adhesively fixed through a coating adhesive 518. When an information carrier plate for displaying information (including passenger information or advertising information) is provided on the outside of the center plate 510, a transparent plastic plate is provided on the outermost side so that the information carrier plate (such as a printed poster) between the plastic plate and the center plate 510 is clearly visible. The plastic plate can not only fix the information carrier plate but also protect it from the outside;

[0055] The frame 511 is a lightweight metal strip, and the end 5110 is cleverly matched with the boss 5270 provided on the guide seat 5207, as Figure 15 shown, effectively improving the connection strength between the wall panel assembly 51 and the fixator 52, improving the reliability of the wall panel assembly 51. The frame 511 also has an extension 5113 that covers the core shaft 5206, the fixing sleeve 5205, and the guide seat 5207, so that the clearance between the arc portion of its outer convex surface 5111 and the inner concave surface 5202 of the fixator 52 is as small as possible;

[0056] Three mutually parallel stay cables 513 pre-tension the wall panel assembly 51, causing the wall panel assembly 51 to be compressed or bent and in an arc shape at the initial position;

[0057] The locking mechanism 514 and the fastening element 516 are fixedly penetrated with the frame 511 together and are used to connect the wall panel assembly 51 and the fixator 52;

[0058] The core shaft 5206 can be a cylindrical structure, a tubular structure, or a rod-shaped structure and is connected to the fixator base through a fixing sleeve 5205;

[0059] The guide seat 5207 completely surrounds the mandrel 5206, and a bushing 5222 made of plastic material is provided between the two. The bushing 5222 is pressed into the guide seat 5207. Axial grooves are provided on the inner side of the bushing 5222, which can not only enable the guide seat 5207 to rotate freely around the mandrel 5206, but also enable the guide seat 5207 to translate smoothly along the mandrel 5206;

[0060] The wear strip 5213 is made of non-metallic wear-resistant material;

[0061] The mounting seat 5216 has at least three connection positions. As Figure 16 shown, the first connection position is connected to the vehicle 7, the second connection position is arc-shaped, and is rotatably connected to the retainer 52 through the hinge seat 5217, and the third connection position is connected to the torsion spring 5220;

[0062] The torsion spring 5220 can be replaced by a helical spring;

[0063] The cap 5221 closes the outer ends of the two end fixing sleeves 5205 so as to fix the mandrel 5206 in the fixing sleeve 5205;

[0064] The baffle 63 is a flexible structure to prevent passengers from inserting their fingers into the gap between the convex surface 5201 and the vehicle 7;

[0065] The brush 64 plays a role in blocking in the gap between the convex surface 5201 and the vehicle;

[0066] The light strip 66 can also be an LED light strip to illuminate the transition area;

[0067] In addition, both the cover plate 512 and the short cover plate 5204 are made of elastic rubber and are deformable. The edge of the wall panel assembly 51 is flush with the edge of the retainer 52 in the height direction. When a vertical displacement occurs, part of the vertical displacement is absorbed by the cover plate 512 and the short cover plate 5204.

[0068] The wall panel assembly 51 involved in this embodiment can be quickly and conveniently connected to the connecting element, making the assembly easier. The two retainers 52 are connected separately from each other, and the entire wall panel assembly 5 does not need to be assembled integrally:

[0069] First, a frame 511 is connected to the connecting element through a fastening element 516 passing through the fastening hole 5112. Since the wall panel assembly 51 can rotate around the mandrel 5206, the fastening element 516 is installed by means of the positioning function of the center pin 5200 and the hook 517;

[0070] Then, another frame 511 is moved towards the retainer 52 or the connecting element. Since the wall panel assembly 51 can rotate around the mandrel 5206, by means of the guiding function of the guide plate 515 inserted into the guide groove 5215, the wall panel assembly 51 is connected or unlocked through the locking mechanism 514;

[0071] Finally, inside the vehicle 7, i.e., on the passenger side, a tool is used to rotate the lock core 5143 so that the lock core 5143 is screwed into or out of the lock seat 5210, and the wall plate assembly 51 is connected and separated from the connecting element. The interaction between the inner wall and the inclined surface 5147 provided inside the lock cover 5141 and the rubber ring 5144 can ensure that the lock core 5143 is centered during the process of being released and connected in the unlocked state.

[0072] When connecting and disconnecting the vehicle 7, using this connection method can ensure that the wall panel assembly 5 can be installed and disconnected quickly and easily.

[0073] When the tunnel device with a shielding mechanism involved in this embodiment is used, the wall panel assembly 5 is connected to the end of the vehicle 7 through the mounting seat 5216, and the shielding mechanism 6 is fixedly mounted on the end of the vehicle 7 through the angle plate 62;

[0074] When the wall panel component 5 is in the initial position, Figure 17 As shown: the two vehicles 7 do not have relative movement, the first stop 5218 and the second stop 5219 limit the rotational movement of the fixer 52 around the rotation axis, in one rotational direction, the first stop 5218 contacts the support panel 5203, and in the other rotational direction, the second stop 5219 contacts the first limiting surface 5300 of the counter-stop formed by the support panel 5203, preventing the fixer 52 from excessive rotational movement around the rotation axis, based on this, when the wall panel assembly 5 is in the initial position, the fixer 52 can rotate freely in two rotational directions, and the wall panel assembly 51 can rotate around the core shaft 5206. Due to the tensioning effect of the cable 513 or the torsion spring 5220 on the wall panel assembly 51, the wall panel assembly 51 bends outward (in the direction of the center of the channel) at the initial position, and the rotation of the connecting element around the core shaft 5206 is self-adjusted for the first time.

[0075] When the wall panel component 5 is in the compressed position, Figure 18 As shown: due to the relative movement between the vehicles 7, the mounting seats 5216 on both sides approach each other, and the fixture 52 rotates around the rotation axis. When the first stop 5218 contacts the support panel 5203, the rotation movement reaches the limit. At the same time, the connecting element rotates outward around the core shaft 5206, partially compensating for the rotation movement of the fixture 52. The rotation of the connecting element around the core shaft 5206 is self-adjusted again. Based on this, the wall panel assembly 51 is more bent in the compressed position than the initial position. The approach of the vehicle or the mounting seat 5216 is compensated by further rotation movement of the connecting element and further bending of the wall panel assembly 51.

[0076] When the wall panel component 5 is in the extended position, Figure 19As shown: The vehicle 7 or the mounting seat 5216 move away from each other due to the relative movement of the vehicle 7, that is, the distance between the mounting seats 5216 is greater than the initial position. The retainer 52 rotates around the rotation axis in a direction opposite to the compression position. The second stopper 5219 contacts the first limiting surface 5300, and the retainer 52 no longer rotates further. The two stopping surfaces contact each other, and the rotational movement of the retainer 52 can be restricted regardless of the rotation direction. The connecting element rotates inward relative to the initial position, partially compensating for the movement of the mandrel 5206, so that the wall panel assembly 51 still has a curvature. Starting from the illustrated position, if the vehicles 7 are to move further apart, it can be compensated by further rotating the connecting element, increasing the length of the extension cable 513, and reducing the curvature of the wall panel assembly 51. During the elongation of the wall panel assembly 5, the vehicle 7 or the mounting seat 5216 generates a lateral displacement perpendicular to the running direction of the train due to the relative movement of the vehicle, and there is a difference from the torque of the torsion spring 5220. The rotation angles between the retainers 52 are not synchronized, resulting in noise or excessive wear due to the contact and friction between the hinge seat 5217 and the connecting element. This defect is remedied by the contact between the limiting surface 5400 of the hinge seat 5217 and the wear strip 5213. The mandrel 5206 moves along a circumferential trajectory around the rotation axis, compensating for a part of the distance change between the vehicle 7 or the fixed seat 5216. The other part of the distance change between the vehicle 7 or the fixed seat 5216 is compensated accordingly by the rotation of the connecting element around the mandrel 5206 in combination with the change in the curvature of the wall panel assembly 51.

A lock seat is also provided on the guide seat. The positioning spring is provided between the positioning sleeve and the positioning seat. An adjusting mechanism is provided on at least one positioning spring. The guide seat and the positioning seat are connected by a connecting bar. Abrasion strips and a positioning plate or a center pin are provided on the connecting bar. A guide groove is provided on the positioning plate. The support panel and the mounting seat are connected through a hinge seat. The mounting seat with at least two stops is connected to the torsion spring. The torsion spring is provided between the mounting seat and the hinge seat. The adjusting mechanism is composed of two plug-connected adjusting sleeves, one on top of the other.

7. A through-channel device with an occlusion mechanism according to claim 6, characterized in that, The main structure of the blocking mechanism includes a fixing plate and angle plates provided at both ends thereof, a baffle and a brush provided on the back surface in an inclined manner, and an adhesive tape and a light strip provided on the front surface; the baffle and the brush have different inclined directions and have a tendency to intersect.

8. The through-channel device with an occlusion mechanism according to claim 7, characterized in that, The main structure of the wall panel assembly further includes a support assembly provided at the bottom of the wall panel component; the main structure of the support assembly includes a seat plate and a support plate with a V-shaped structure provided thereon.

9. The through-channel device with an occlusion mechanism according to claim 8, characterized in that, The fixator rotates around the rotation axis formed by the two mounting seats, and the torsion spring applies a torque to the fixator so as to pull the wall panel component towards the vehicle connected to the fixator. The convex surface of the fixator rotates around the rotation axis during the movement. The connecting element rotates around the mandrel and rotatably connects the wall panel component to the fixator. At the same time, the guide seat can move on the mandrel, so that the connecting element and the wall panel component connected thereto move relative to the fixator in the height direction along the mandrel. Through the movement of the guide seat on the mandrel, the wall panel component translates relative to the fixator to compensate for the vertical deviation between the two vehicles. One end of the positioning spring is supported on the fixing sleeve, and the other end is supported on the guide seat. A prestress is applied between the two through the adjusting mechanism to position the wall panel component along the mandrel or restore the wall panel component to the initial position after the vertical displacement ends.

10. The through-channel device with an occlusion mechanism according to claim 8, characterized in that, When the wall panel component is displaced, the lower edge and the upper edge move parallelly, and the deformation is evenly distributed on the cover plate and the short cover plate. When the cover plate and the short cover plate collide with the top plate assembly or the floor assembly, deformation occurs. The extension amount of the cover plate and the short cover plate parallel to the height direction is equivalent to 5% to 20% of the dimension of the retainer in the same direction. After one side of the wall panel assembly is opened, the support assembly provides support. When the vehicle turns, the cable and the torsion spring cooperate together to make the wall panel assembly return to the starting position immediately after the turn is completed. During this period, the wall panel assembly is stretched on the outer side of the turn and compressed on the inner side of the turn.
