Description

Technical Field

[0001] This invention relates to the technical fields of rail vehicle equipment, and in particular to an integrated sidewall system for through passageways. Background Technology

[0002] As a component of rail vehicles, the connecting passageway connects two adjacent carriages. The side wall panel system is a major component of the connecting passageway. During application, the side wall panel system is pre-tensioned by torsion springs between the side wall panels and the car body, thus securing the side wall panel system between the two carriages. After the torsion springs rotate, they need to be locked using locking devices such as pins. However, these locking devices can come loose due to vehicle vibrations. For example, a rail vehicle connecting passageway guard plate structure disclosed in patent number CN214084237U and a side wall assembly disclosed in patent number CN217969512U both use connecting devices to fix the side wall assembly to the car body. Both use locking hooks and elastic elements to lock and restrict the connection between the side wall panel and the car body. In actual use, the locking device can loosen due to the shaking of the side wall panel, posing a safety hazard. Summary of the Invention

[0003] The technical problem this invention aims to solve is that the connection between the side wall panels of the through passage and the vehicle body is prone to loosening, posing a safety hazard.

[0004] The technical solution adopted by this invention to solve its technical problem is: a through-passage integrated sidewall system, including a sidewall panel, a split-type connecting mechanism installed on both sides of the sidewall panel, and a rotary cylinder locking mechanism installed in the split-type connecting mechanism. The split-type connecting mechanism includes a connecting column fixed to the end face of the carriage, an elastic element device sleeved on the connecting column, and a pressing edge device distributed on the connecting column. The elastic element device is connected to the sidewall panel. The pressing edge device includes a pressure plate profile rotatably installed on the connecting column. The pressure plate profile is detachably connected to the sidewall panel, and a locking groove is opened on the pressure plate profile. The rotary cylinder locking mechanism includes a locking disc installed at the top of the connecting column, a locking block telescopically received in the locking disc, a first elastic element installed between the locking disc and the locking block, and a rotating element disposed in the locking block. The rotating push assembly and the locking assembly controlling the movement stroke of the rotating push assembly are described. The locking disc has a first clearance groove, and a locking post is vertically protruding from the side of the locking block. The locking post can pass through the first clearance groove and then be inserted into the locking groove. The locking post and the first elastic member are respectively disposed on both sides of the locking block. The rotating push assembly includes a rotatable cam installed in the locking block and a control post controlling the rotation of the cam. The locking assembly includes a brake sleeve movably sleeved on the control post, a second elastic member housed in the brake sleeve, and a travel-limiting protrusion protruding on the cam. The brake sleeve has a brake groove, which is set according to the rotation angle of the pressure plate profile. The travel-limiting protrusion can be housed in the brake groove. The two ends of the second elastic member are respectively attached to the inner wall of the brake sleeve and the control post.

[0005] Furthermore, the locking disc has a receiving groove, and the first clearance groove is formed on the groove wall of the receiving groove, and the locking block is movably received in the first clearance groove.

[0006] Furthermore, the bottom of the receiving groove has a second clearance groove, and the end of the control column can be pushed into the second clearance groove to rotate.

[0007] Furthermore, the control column is provided with a shoulder, the brake sleeve is covered on the shoulder, and the two ends of the second elastic member are placed between the shoulder and the brake sleeve.

[0008] Furthermore, the end face of the brake sleeve facing away from the cam has a structure that collapses and shrinks towards the center.

[0009] Furthermore, the locking block has a track groove, which is set according to the rotation trajectory of the cam, and the cam is rotatably set in the track groove.

[0010] Furthermore, the first elastic element is symmetrically distributed about the axis of the locking pin.

[0011] Furthermore, the locking disc is fixed to the connecting post by a key connection.

[0012] Furthermore, the pressing device also includes a pressing connecting seat installed on the connecting column, and the pressing plate profile is fixed on the pressing connecting seat.

[0013] Furthermore, the elastic element device also includes a torsion spring sleeved on the connecting column, a torsion spring fixing seat fixed on the connecting column, and a torsion spring rotating seat rotatably sleeved on the connecting column. The two ends of the torsion spring are respectively fixed on the torsion spring fixing seat and the torsion spring rotating seat, and the torsion spring rotating seat is fixed to the pressure plate profile.

[0014] The beneficial effects of this invention are that the side wall panel tends to tighten under the constraint of the pressure plate profile. When the side wall panel tends to tighten under the action of the elastic element device, after the side wall panel is tightened, the cam is controlled to rotate in the locking block by the control column in the rotary cylinder locking mechanism. The cam pushes the locking block inside the locking block. With the elastic control of the first elastic element, the position of the locking pin on the locking block relative to the locking groove can be changed. After the position of the locking block is adjusted to the correct position, the control column is pressed relative to the brake sleeve. With the cooperation of the second elastic element, the contact strength between the cam and the brake sleeve is changed, thereby improving the locking degree of the locking pin in the locking groove. This strengthens the connection between the side wall panel and the vehicle body, prevents the connection structure between the two from loosening, and avoids safety hazards.

Detailed Implementation

[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0029] like Figures 1 to 11 As shown, the present invention provides an integrated sidewall system 100 for a through passageway, including a sidewall panel 10, a split connecting mechanism 60 installed on both sides of the sidewall panel 10, and a rotary cylinder locking mechanism 70 installed in the split connecting mechanism 60.

[0030] like Figure 1 and Figure 2As shown, the side wall panel 10 is a flexible wall panel made of resin material. The side wall panel 10 has extensibility and elasticity, and the two sides of the side wall panel 10 have a rolled structure.

[0031] like Figure 2 As shown, the split-type connecting mechanism 60 includes a track bend plate 20, a connecting column 30 fixed to the end face of the carriage, an elastic element device 40 sleeved on the connecting column 30, and pressing devices 50 distributed on the connecting column 30. The track bend plate 20 is arc-shaped and fixed to the side of the side wall plate 10. The connecting column 30 is located at the center position inside the side of the side wall plate 10. The elastic element device 40 includes a torsion spring 410 sleeved on the connecting column 30, a torsion spring fixing seat 420 fixed on the connecting column 30, and a torsion spring rotating seat 430 rotatably sleeved on the connecting column 30. The torsion spring 410 is rotatably sleeved onto the connecting post 30. The torsion spring fixing seat 420 and the torsion spring rotating seat 430 are respectively disposed at both ends of the connecting post 40. The two ends of the torsion spring 410 are respectively fixed to the torsion spring fixing seat 420 and the torsion spring rotating seat 430. One end of the torsion spring 410 is fixed relative to the connecting post 30 through the torsion spring fixing seat 420, and the other end of the torsion spring 410 is rotatable relative to the connecting post 30 through the torsion spring rotating seat 430. When the torsion spring rotating seat 430 rotates relative to the torsion spring fixing seat 420, a preload can be applied to the torsion spring 410. Under the drive of the torsion spring 410, the torsion spring rotating seat 430 has a tendency to rotate relative to the connecting post 30.

[0032] like Figure 2 and Figure 3 As shown, the pressing device 50 includes a pressing connecting seat 510 rotatably mounted on the connecting column 30 and a pressing plate profile 520 fixedly mounted on the pressing connecting seat 510. There are at least two pressing connecting seats 510. The pressing plate profile 520 is generally a curved plate profile structure. The rotation axis of the pressing plate profile 520 coincides with the axis of the connecting column 30, meaning the pressing plate profile 520 rotates around the connecting column 30. Two parallel locking grooves 521 are opened on the side of the pressing plate profile 520 facing the connecting flange 511. The spacing between the locking grooves 521 is the same as that of the pressing plate profile 520. The pressing plate profile 520 is detachably connected to the track bend plate 220. When the pressing plate profile 520 rotates relative to the connecting column 30, the side wall plate 10 can deform and stretch following the rotation of the track bend plate 220. When the side wall plate 10 deforms and stretches on both sides, the side wall plate 10 is tightened between the two track bend plates 220.

[0033] like Figures 2 to 5As shown, the rotary drum locking mechanism 70 includes a locking disc 710 mounted on the top of the connecting column 30, a retractable locking block 720 housed in the locking disc 710, a first elastic member 730 mounted between the locking disc 710 and the locking block 720, a rotary pushing assembly 740 disposed in the locking block 720, and a locking assembly 750 for controlling the movement stroke of the rotary pushing assembly 740.

[0034] like Figure 3 As shown, the locking disc 710 is fixedly sleeved on the connecting post 30. Preferably, the locking disc 710 is fixed to the connecting post 30 by a key connection. The locking disc 710 has a first clearance groove 711 corresponding to the locking groove 521. The locking disc 710 also has a receiving groove 712. The first clearance groove 711 is formed on the groove wall of the receiving groove 712. The locking block 720 is movably received in the receiving groove 712. The locking block 720 is generally square block structure. A locking post 721 is vertically protruding on the side of the locking block 720. The locking post 721 can pass through the first clearance groove 711 and then be inserted into the locking groove 521. Under the restriction of the locking post 721, the pressure plate profile 520 is fixed relative to the connecting post 30.

[0035] like Figure 3 and Figure 4 As shown, the end of the first elastic member 730 abuts against the groove wall of the receiving groove 712 and the locking block 720. The first elastic member 730 is preferably a spring. The first elastic member 730 is symmetrically distributed about the axis of the locking pin 721. The first elastic member 730 and the locking pin 721 are respectively disposed on both sides of the locking block 720. Under the action of the first elastic member 730, the locking block 720 always maintains the tendency to extend out of the first relief groove 712. That is, when the first relief groove 712 and the locking groove 521 are aligned, the locking block 720 is pushed by the first elastic member 730, pushing the locking pin 721 into the locking groove 521.

[0036] like Figure 4 As shown, the locking block 720 has a track groove 722. The rotating pushing assembly 740 includes a cam 741 rotatably disposed within the track groove 722 and a control post 742 fixedly connected to the cam 741. The track groove 722 is machined according to the rotation trajectory of the cam 741. During the rotation of the cam 741, by pushing against the wall of the track groove 722, the position of the locking block 720 within the receiving groove 712 can be changed. At the same time, in conjunction with the constraint of the receiving groove 712 on the locking block 720, the movement stroke of the locking block 720 can be limited. The control post 742 passes through the cam 741 and then inserts into the locking disc 710. The control post 742 and the cam 741 are fixedly connected.

[0037] like Figures 5 to 11As shown, the locking assembly 750 includes a brake sleeve 751 movably sleeved on the control column 742, a second elastic member 752 housed in the brake sleeve 751, and a limit protrusion 753 protruding on the cam 741.

[0038] Preferably, such as Figure 7 As shown, a second clearance groove 713 is formed on the bottom of the receiving groove 712. The end of the control post 742 can be received and rotated within the second clearance groove 713. Preferably, a shoulder 743 is provided on the control post 742, and the control post 742 passes through the shoulder 743 into the cam 741. The brake sleeve 751 is disposed above the locking block 720. The brake sleeve 751 is slidably sleeved on the control post 742, and the brake sleeve 751 is disposed covering the shoulder 743. Figures 9 to 11 As shown, a brake groove 754 facing the cam 741 is formed on the end face of the brake sleeve 751. The second elastic member 752 is preferably a spring. The second elastic member 752 is sleeved on the shoulder 743 and rests between the shoulder 743 and the brake sleeve 751. One end of the second elastic member 752 abuts against the end face of the shoulder 743, and the other end abuts against the end face of the brake sleeve 751. Under the support of the second elastic member 752, the end face of the cam 741 and the brake sleeve 751 are in contact. The brake groove 754 is set according to the rotation angle of the pressure plate profile 520. The travel-limiting protrusion 753 is movably inserted into the brake groove 754. The travel-limiting protrusion 752 is restricted by the brake groove 754 and can control the position of the cam 741 relative to the locking block 720.

[0039] Specifically, when the locking assembly 750 is in use, the control pin 742 first moves relative to the brake sleeve 751 towards the cam 741. The control pin 742 causes the cam 741 to disengage from the brake sleeve 751, and the end of the control pin 742 is moved into the second clearance groove 713, that is, the travel-limiting protrusion 753 can disengage from the brake groove 754. The cam 741 can rotate relative to the locking block 720. When the cam 741 rotates within the locking block 720, it changes the pushing position of the cam 741 against the locking block 720, thereby changing the position of the locking block 720 in the receiving groove 712 and controlling the position of the locking pin 721 relative to the locking groove 521. When the cam 741 rotates to its position, that is, after the locking pin 721 extends or retracts from the first clearance groove 711, under the action of the second elastic element 752, the travel-limiting protrusion 752 returns to the brake groove 754, thus limiting the rotation stroke of the cam 741.

[0040] Preferably, such as Figure 8As shown, the end of the control column 742 away from the cam 741 has a polygonal column structure. The operator can use a special-shaped wrench or other tools to put on the end of the control column 742 and drive the control column 742 to rotate. While driving the cam 741 to rotate, the position of the limit protrusion 752 relative to the brake groove 754 is adjusted.

[0041] Preferably, a guide sleeve 755 is provided on the end face of the brake sleeve 751 away from the cam 741. The end face of the guide sleeve 755 away from the brake sleeve 751 has a structure that collapses and shrinks towards the center. That is, the end of the control column 742 can be protected by the guide sleeve 755. At the same time, under the restriction of the end face of the guide sleeve 755, the time for the operator to find the end of the control column 742 is reduced.

[0042] When the aforementioned through-passage sidewall system 100 is assembled and used, the side edge of the sidewall panel 10 is bent and rolled along the track bend plate 20, and the track bend plate 20 is fixed to the sidewall panel 10. The connecting column 30 can be fixed to the end face of the carriage through the mounting base 310. The pressure plate profile 520 is fixed to the connecting column 30. After being pushed, the pressure plate profile 520 is fixed to the track bend plate 20. After the pressure plate profile 520 rotates, it can pull the sidewall panel 10 to rotate synchronously, so that the sidewall panel 10 is tightly fixed between the two connecting columns 30. During the rotation of the pressure plate profile 520, the locking groove 521 on the pressure plate profile 520 rotates relative to the first clearance groove 711. When the pressure plate profile 520 rotates to the position, the pressure control column 74 is pressed down. 2. This causes the limiting protrusion 752 on the cam 741 to disengage from the brake groove 754. The control column 742 can drive the cam 741 to rotate relative to the locking block 720. During the rotation, the cam 741 pushes against the locking block 720 until the locking column 721 passes through the first clearance groove 711 and enters the locking groove 521. Under the insertion and fixation of the locking column 721, the rotation stroke of the pressure plate profile 520 is restricted, so that the side wall plate 10 remains in a tight and fixed state. Then, the pressure on the control column 742 is released, and the control column 742 drives the cam 741 to reset under the action of the second elastic element 752, so that the limiting protrusion 752 resets back into the brake groove 754, and the position of the cam 741 relative to the locking block 720 is fixed.

[0043] When it is necessary to remove the side wall panel 10 from the carriage, the worker first inserts a wrench into the guide sleeve 755. Under the guidance of the end face of the guide sleeve 755, the wrench and other tools can fit onto the polygonal end of the control column 742. The control column 742 is then pressed down again and rotated in the opposite direction until the locking column 721 disengages from the locking groove 521, releasing the pressure on the control column 742. The limit protrusion 752 returns to the brake groove 754. At the same time, under the action of the torsion spring 410, the pressure plate profile 520 returns to the starting position, and the side wall panel 10 is in a relaxed and retracted state. This allows the sealing position of the side wall panel 10 via the track bend plate 220 to be opened, and the worker can then disassemble the side wall panel 10.

[0044] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
