Description

Technical Field

[0001] The present invention relates to the technical field of wheeled cargo transport vehicles, and more specifically, to a ferry assembly and a wheeled cargo transport vehicle. Background Art

[0002] With economic development and the improvement of residents' living standards, cars have gradually entered thousands of households. The concentration of automobile manufacturing bases and the dispersion of consumer markets have brought huge demands for automobile logistics. Railway transportation can better protect the quality of the transported cars, and the freight volume is increasing year by year.

[0003] Railway freight cars are usually made up of multiple vehicles connected in sequence. In order to ensure the safe passage of people and goods (usually cars) between vehicles, two adjacent vehicles of railway freight cars are connected by a ferry at the end of the vehicle, so that the goods can be transferred through the ferry. When in use, manual operation is required to lay the ferry flat (i.e., working position); when not in operation, the ferry needs to be erected or folded (non-working position) to avoid interference between the ferry and the vehicle during operation. With the increase in manual operation costs, convenient operation and simple maintenance have become an important part of reducing transportation costs.

[0004] Therefore, how to simplify the operation steps when the bridge is switched between the working position and the non-working position is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0005] In view of this, an object of the present invention is to provide a ferry assembly to simplify the operation steps when the ferry body is switched between the working position and the non-working position;

[0006] Another object of the present invention is to provide a wheeled cargo transport vehicle having the above-mentioned ferry assembly.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A ferry assembly, comprising:

[0009] at least one ferry board mounting seat having a first mounting portion for mounting on the chassis of the wheeled cargo transport vehicle;

[0010] A ferry board body and a limit connection seat, wherein the limit connection seat is fixed to the ferry board body and is hinged to the ferry board mounting seat through a hinge pin, so that the ferry board body can swing between a working position and a non-working position, the limit connection seat is arranged in a one-to-one correspondence with the ferry board mounting seat, and at least one of the limit connection seats is provided with a limit assembly;

[0011] A limiting device is arranged on the corresponding ferry board mounting seat corresponding to the limiting assembly, and the limiting device can move between a first position and a second position. When the limiting device is in the first position and the ferry board body is in the working position and the non-working position, the limiting device forms a limit on the limiting assembly. When the limiting device is in the second position, the limiting device avoids limiting the limiting assembly.

[0012] Optionally, in the above-mentioned ferry assembly, the limiting device is a limiting shaft rotatably arranged on the ferry mounting seat, and an avoidance notch is arranged at the shaft section corresponding to the limiting shaft and the limiting assembly;

[0013] When the limiting device rotates to the first position, the avoidance gap faces away from the hinge pin shaft, and when the limiting device rotates to the second position, the avoidance gap faces the hinge pin shaft.

[0014] Optionally, in the above-mentioned ferry assembly, a rotating wrench is eccentrically provided at one end of the limiting device extending outward from the ferry mounting seat;

[0015] When the limiting device rotates to the first position, the center of gravity of the rotating wrench is located below the limiting device, and when the limiting device rotates to the second position, the center of gravity of the rotating wrench is located above the limiting device.

[0016] Optionally, in the above-mentioned ferry assembly, the limit connection seat includes:

[0017] A connecting seat body, wherein the connecting seat body has a ferry board mounting surface for fixing the ferry board body;

[0018] The hinged ear plate is connected to the connecting seat body, the hinged ear plate has a hinge hole for the hinge pin to pass through, and the limiting assembly is arranged on the hinged ear plate.

[0019] Optionally, in the above-mentioned ferry assembly, the limiting assembly includes a first limiting portion and a second limiting portion;

[0020] When the limiting device is in the first position and the ferry body is in the working position, the first limiting portion abuts against the limiting device; when the ferry body is in the non-working position, the second limiting portion abuts against the limiting device.

[0021] Optionally, in the above-mentioned ferry assembly, the ferry mounting seat has a first abutting surface, and the position-limiting connecting seat has a second abutting surface;

[0022] When the limiting device is in the first position and the ferry board body is in the working position, the limiting device abuts against the first limiting portion to limit the ferry board body from rotating in a first direction, and the first abutting surface abuts against the second abutting surface to limit the ferry board body from rotating in a second direction, and the first direction and the second direction are opposite.

[0023] Optionally, in the above-mentioned ferry assembly, the ferry mounting seat has a third abutment surface;

[0024] When the limiting device is in the first position and the ferry board body is in the non-working position, the limiting device abuts against the second limiting portion to limit the ferry board body from rotating in the second direction, and the third abutting surface abuts against the outer surface of the ferry board body to limit the ferry board body from rotating in the first direction, and the first direction is opposite to the second direction.

[0025] Optionally, in the above-mentioned ferry board assembly, there are two ferry board mounting seats, only one of which is provided with the limiting device, and the ferry board mounting seat provided with the limiting device is located at the end of the ferry board body.

[0026] The ferry board assembly provided by the present invention is connected to the base frame through its ferry board mounting seat, the limit connection seat is hinged to the ferry board mounting seat through a hinge pin, and the ferry board body is fixed on the limit connection seat. The ferry board body can be driven to switch between the working position and the non-working position through the limit connection seat. And at least one limit connection seat is provided with a limit assembly, and a limit device is correspondingly provided on the limit connection seat provided with the limit assembly. The limit device can move between the first position and the second position. When the limit device is switched to the first position, it can prevent the ferry board mounting seat and the ferry board body from rotating relative to each other by cooperating with the limit assembly. That is, when the ferry board body is in the working position and the non-working position, the limit device can be switched to the first position, so that the ferry board body is limited in the working position and the non-working position and cannot vibrate due to external force. When the ferry board body needs to swing between the working position and the non-working position, it only needs to switch the limit device to the second position. According to the present invention, after the ferry board body is switched to the working position or the non-working position, it is only necessary to switch the limit device to the first position to complete the limit. When the ferry board body needs to swing between the working position and the non-working position, it is only necessary to switch the limit device to the second position, thereby simplifying the operation steps when the ferry board body is switched between the working position and the non-working position.

[0028] chassis;

[0029] The ferry board assembly is arranged at both ends of the base frame, and the ferry board assembly is the ferry board assembly as described in any one of the above items.

[0056] The core of the present invention is to provide a ferry assembly to simplify the operation steps when the ferry body is switched between the working position and the non-working position;

[0057] Another core of the present invention is to provide a wheeled cargo transport vehicle having the above-mentioned ferry assembly.

[0058] The following embodiments are described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention contents described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions to the inventions described in the claims. It should be noted that, for ease of description, only the parts related to the inventions are shown in the accompanying drawings. The embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0059] Figure 1-Figure 3 The structure of the ferry assembly used in the SQ6 vehicle is shown, and the ferry assembly mainly includes the ferry body 2, the tie rod 4, the connecting pin seat, the pillar 1, the locking hook 5 and other parts. The tie rod 4 consists of two sections, namely the first section tie rod 41 and the second section tie rod 42. The first section tie rod 41 and the second section tie rod 42 are hinged by a hinge pin 43, and the two ends of the tie rod 4 are hinged to the pillar 1 and the ferry body 2 respectively.

[0060] When the ferry assembly is in the non-working position, the ferry body 2 is erected and can be raised and lowered together with the movable base frame 3; when the ferry assembly is in the working position, open the locking hook 5, move the ferry body 2, make the two sections of the tie rod (the first section tie rod 41 and the second section tie rod 42) on the same axis, and then put the anti-jump ring 44 of the tie rod at the connection between the first section tie rod 41 and the second section tie rod 42 to prevent the ferry body 2 from jumping when wheeled goods pass. When the ferry body 2 is closed, first push the anti-jump ring 44 between the first section tie rod 41 and the second section tie rod 42 upward to disengage it from the connection between the two tie rods, push the ferry body 2 upward to make it erect, and at this time, observe that the locking hooks on both sides of the ferry body 2 hook the stop pins on the ferry at the same time to make it completely fixed.

[0061] The operation process of the above scheme is relatively complicated. It takes three steps to turn the board body 2 from upright to flat (1. Open the locking hook 5; 2. Move the board body 2; 3. Move the anti-jump ring 44), and two steps to restore it to the upright state (1. Move the anti-jump ring 44; 2. Move the board body 2). The locking and disengagement of the anti-jump ring 44 require the first section of the pull rod 41 and the second section of the pull rod 42 to be coaxial, and this process requires adjusting the angle of the board body 2. The manpower time consumed by the board body 2 structure in the process of switching workstations needs to be improved.

[0062] Based on this, an embodiment of the present invention discloses a ferry assembly to simplify the operation steps when the ferry body switches between the working position and the non-working position. Figure 4 As shown, the ferry assembly disclosed in the embodiment of the present invention includes a ferry mounting seat 200 , a ferry body 100 , a limiting connecting seat 300 and a limiting device 500 .

[0063] like Figure 7 and Fig.11As shown, there is at least one ferry board mounting seat 200, and it has a first mounting portion 201 for mounting on the chassis 700 of the wheeled cargo transport vehicle. Specifically, the first mounting portion 201 extends to one side of the main body of the ferry board mounting seat 200, so that the first mounting portion 201 can be attached to the chassis 700 to facilitate fixed connection with the chassis 700. Specifically, the first mounting portion 201 can be welded to the chassis 700, or can be detachably fixed to the chassis 700 by fasteners. The specific fixing method is not limited, as long as the assembly of the ferry board mounting seat 200 and the chassis 700 can be achieved.

[0064] like Figure 6 and Figure 7 As shown, the limit connecting seat 300 is fixed on the ferry board body 100. The limit connecting seat 300 can be directly welded on the ferry board body 100, or can be detachably fixed on the ferry board body 100 by fasteners. The specific fixing method is not limited as long as the assembly of the limit connecting seat 300 and the ferry board body 100 can be achieved.

[0065] The limit connection seat 300 is hinged to the ferry mounting seat 200 through the hinge pin 400, so that the ferry body 100 can swing between the working position and the non-working position. It can be understood by those skilled in the art that the working position of the ferry body 100 usually refers to the position where the ferry body 100 is parallel to the base frame 700, and of course, it can also have a smaller angle with the base frame 700, as long as it can facilitate wheeled goods (usually cars, it should be noted that car is a general name, not limited to vehicles fueled by gasoline, but also should include new energy vehicles, diesel vehicles, natural gas vehicles, etc.) to pass through the ferry body 100 and pass between vehicles of wheeled cargo transport vehicles.

[0066] The limiting connection seats 300 are arranged one by one with the ferry mounting seats 200, and at least one limiting connection seat 300 is provided with a limiting assembly 303. Figure 4 As shown, usually two limit connection seats 300 and two ferry mounting seats 200 can be correspondingly arranged on each ferry body 100 to improve the stability of the installation. It is sufficient to arrange the limit assembly 303 on one of the limit connection seats 300.

[0067] The limiting device 500 and the limiting assembly 303 are correspondingly arranged on the corresponding ferry board mounting seat 200, that is, the limiting device 500 and the limiting assembly 303 correspond one to one, and the limiting device 500 is only installed correspondingly for the ferry board mounting seat 200 that cooperates with the limiting connecting seat 300 having the limiting assembly 303. Only one of the ferry board mounting seats 200 is provided with the limiting device 500, and the ferry board mounting seat 200 provided with the limiting device 500 can be located at the end of the ferry board body 100 to facilitate the operation of the limiting device 500.

[0068] The limiting device 500 can move between the first position and the second position, and the limiting device 500 can move or rotate between the first position and the second position. This embodiment does not limit the switching mode of the limiting device 500 between the first position and the second position.

[0069] When the limiting device 500 is in the first position and the ferry body 100 is in the working position and the non-working position, the limiting device 500 forms a limit on the limiting component 303. When the limiting device 500 is in the second position, the limiting device 500 avoids limiting the limiting component 303.

[0070] The limit assembly 303 protrudes outward from the rotation center of the limit connecting seat 300, so it has a larger rotation radius than other positions and is more easily blocked by the limit device 500. Therefore, the limit assembly 303 can be blocked by changing the position of the limit assembly 303, and then the ferry body 100 can be limited to the working position and the non-working position.

[0071] It should be noted that, according to the actual application scenario, those skilled in the art may choose to limit the rotation of the limit connecting seat 300 in two directions by cooperating with the limit assembly 303 and the limit device 500; or may choose to limit the rotation of the limit connecting seat 300 in only one direction, and limit the rotation in the other direction by other means, such as limiting by abutment with other components.

[0072] In summary, the ferry assembly disclosed in this embodiment is connected to the base frame 700 through its ferry mounting seat 200, the limit connection seat 300 is hinged to the ferry mounting seat 200 through the hinge pin 400, and the ferry body 100 is fixed to the limit connection seat 300. The limit connection seat 300 can drive the ferry body 100 to switch between the working position and the non-working position. And at least one limit connection seat 300 is provided with a limit assembly 303, and the limit device 500 is correspondingly provided on the limit connection seat 300 provided with the limit assembly 303. The limit device 500 can move between the first position and the second position. When the limit device 500 is switched to the first position, it can prevent the ferry body 100 and the ferry mounting seat 200 from rotating relative to each other by cooperating with the limit assembly 303. That is, when the ferry board body 100 is in the working position and the non-working position, the limiting device 500 is switched to the first position, so that the ferry board body 100 is limited in the working position and the non-working position and cannot vibrate due to external force. When the ferry board body 100 needs to swing between the working position and the non-working position, it only needs to switch the limiting device 500 to the second position.

[0073] Compared with the ferry boards of existing wheeled transport vehicles, the ferry board assembly disclosed in this embodiment does not need to be provided with pillars extending upward along the base frame, rarely encroaches on the space of the base frame, increases the space utilization rate of the base frame, and can load larger and longer cargoes on the base frame.

[0074] In the present invention, after the ferry board body 100 is switched to the working position or the non-working position, it is only necessary to switch the limiting device 500 to the first position. When the ferry board body 100 needs to swing between the working position and the non-working position, it is only necessary to switch the limiting device 500 to the second position. In the present invention, it is only necessary to switch the limiting device 500 between the first position and the second position. When limiting the position of the ferry board body 100, it is not necessary to adjust the angle of the ferry board body 100, which simplifies the operation steps when the ferry board body 100 is switched between the working position and the non-working position.

[0075] In a specific embodiment of the present invention, the limiting device 500 may be a limiting shaft rotatably disposed on the ferry mounting seat 200. Figure 5 As shown, the shaft section corresponding to the limiting shaft and the limiting assembly 303 is provided with an avoidance notch 5011. Specifically, the limiting device 500 may include a limiting shaft body 501 and a limiting plate 502 disposed at one end of the limiting shaft body 501, and the avoidance notch 5011 is provided on the limiting shaft body 501.

[0076] The ferry mounting seat 200 has a rotation hole matched with the limiting shaft body 501. The limiting shaft body 501 is inserted into the rotation hole, and one end of the limiting shaft body 501 is limited by the limiting plate 502. The other end of the limiting shaft body 501 can be limited by inserting a pin. Specifically, a first limiting insertion hole 5012 can be provided in the limiting shaft body 501. After the limiting shaft body 501 is inserted into the rotation hole, one end is against the limiting plate 502, and the other end is limited by inserting a pin in the first limiting insertion hole 5012 to prevent the axis of the limiting shaft body 501 from moving.

[0077] like Figure 8 and Fig.10 As shown, when the limit device 500 rotates to the first position, the avoidance gap 5011 faces away from the hinge pin 400, that is, when the limit connection seat 300 rotates, the limit assembly 303 thereon will not pass through the avoidance gap 5011, so the avoidance gap 5011 will not play the role of avoiding the limit assembly 303, and the other parts of the limit shaft body 501 do not have the avoidance function, so they will interfere with the limit assembly 303, making the limit connection seat 300 unable to rotate. Figure 8 as shown) and non-working position (as Fig.10As shown), if the limit device 500 is rotated to the first position, the outer peripheral surface of the limit shaft body 501 is just in contact with the limit component 303, so that the limit connecting seat 300 cannot rotate, and the ferry body 100 can be kept in the working position and the non-working position.

[0078] When the limiting device 500 rotates to the second position, the avoidance notch 5011 faces the hinge pin 400. Since the avoidance notch 5011 is formed by removing a portion of material from the limiting shaft body 501, that is, removing a portion of material that can interfere with the limiting assembly 303, when the avoidance notch 5011 faces the hinge pin 400, the limiting device 500 cannot interfere with the limiting assembly 303, and will not affect the rotation of the limiting connector 300, so that the ferry body 100 can rotate between the working position and the non-working position.

[0079] In order to facilitate the rotation of the limiting device 500, as Figure 4 As shown, in this embodiment, a rotating wrench 600 can be eccentrically arranged at one end of the limit device 500 extending outward from the ferry board mounting seat 200. The limit device 500 is driven to rotate by the rotating wrench 600 to change its first position and second position. Specifically, the rotating wrench 600 can be fixed on the limit device 500 by a positioning pin, and a second limit socket 5013 can be provided on the limit shaft body 501, so that the second limit socket 5013 and the first limit socket 5012 can be spaced apart by a preset distance, and this preset distance can be designed according to the requirements. The setting of the preset distance can make a certain distance between the rotating wrench 600 and the ferry board mounting seat 200, so as to facilitate the operation of the rotating wrench 600.

[0080] After the rotating wrench 600 is sleeved on the limiting shaft body 501, the positioning hole on the rotating wrench 600 can be made to correspond to the second limiting plug hole 5013, and then the rotating wrench 600 can be fixed on the limiting shaft body 501 by inserting the positioning pin, and the limiting shaft body 501 can be rotated by rotating the rotating wrench 600.

[0081] When the stopper 500 rotates to the first position, the center of gravity of the rotating wrench 600 is located below the stopper 500, thereby preventing the stopper 500 from rotating and leaving the first position due to gravity. When the stopper 500 rotates to the second position, the center of gravity of the rotating wrench 600 is located above the stopper 500. The position of the stopper 500, i.e., the position of the avoidance notch 5011, can be identified by observing the position of the rotating wrench 600.

[0082] like Figure 6As shown, in this embodiment, the position limiting connection seat 300 may include a connection seat body 301 and a hinged ear plate 302. The connection seat body 301 has a ferry board installation surface 3011 for fixing the ferry board body 100, and the ferry board body 100 may be welded on the ferry board installation surface 3011.

[0083] The hinged ear plate 302 is connected to the connecting seat body 301. It should be noted that the hinged ear plate 302 and the connecting seat body 301 can be designed as an integrated structure. The hinged ear plate 302 has a hinge hole for the hinge pin 400 to pass through, and the limit assembly 303 is arranged on the hinged ear plate 302.

[0084] Furthermore, the limiting assembly 303 may include a first limiting portion 3031 and a second limiting portion 3032, and the first limiting portion 3031 and the second limiting portion 3032 are both arranged around the hinge hole on the hinge ear plate 302. Figure 8 As shown, when the limiting device 500 is in the first position and the ferry body 100 is in the working position, the first limiting portion 3031 abuts against the limiting device 500; Fig.10 As shown, when the limiting device 500 is in the first position and the ferry body 100 is in the non-working position, the second limiting portion 3032 abuts against the limiting device 500 .

[0085] like Figure 6-Figure 8 As shown, the ferry mounting seat 200 has a first abutting surface 202, and the limiting connecting seat 300 has a second abutting surface 3012. Specifically, the second abutting surface 3012 can be located on the connecting seat body 301. When the limiting device 500 is in the first position and the ferry body 100 is in the working position, the limiting device 500 abuts against the first limiting portion 3031 to limit the ferry body 100 from rotating in the first direction ( Figure 8 In the illustrated embodiment, the first direction is the clockwise direction), the first abutting surface 202 abuts against the second abutting surface 3012 to limit the ferry body 100 from rotating in the second direction ( Figure 8 In the illustrated solution, the second direction is counterclockwise), and the first direction is opposite to the second direction. In this way, the position-limiting connection seat 300 and the ferry body 100 cannot rotate in both directions. In this embodiment, the position of the ferry body 100 is limited by the abutment between the position-limiting connection seat 300 and the ferry mounting seat 200, so that the ferry body 100 can bear greater pressure and ensure the safety of wheeled goods when passing.

[0086] like Fig.10 and Fig.11 As shown, the ferry mounting seat 200 has a third abutting surface 203. When the limiting device 500 is in the first position and the ferry body 100 is in the non-working position, the limiting device 500 abuts against the second limiting portion 3032 to limit the ferry body 100 from moving in the second direction ( Fig.10In the embodiment shown, the second direction is counterclockwise) and the third abutting surface 203 abuts against the outer surface 101 of the ferry body 100 to limit the ferry body 100 from rotating in the first direction ( Fig.10 In the illustrated solution, the first direction is a clockwise direction, and the first direction is opposite to the second direction. In this way, the position-limiting connecting seat 300 and the ferry body 100 cannot rotate in both directions.

[0087] like Fig.11 and Fig.12 As shown, an embodiment of the present invention further discloses a wheeled cargo transport vehicle, which includes a chassis 700 and a ferry assembly. The ferry assembly is the ferry assembly disclosed in the above embodiment. It should be noted that the ferry assembly disclosed in this embodiment can be installed on the upper chassis of the wheeled cargo transport vehicle, and can also be set on the lower chassis. The wheeled cargo transport vehicle provided by the present invention has all the technical effects of the above-mentioned ferry assembly because it has the above-mentioned ferry assembly, which will not be repeated herein.

[0088] Two ferry assemblies are arranged at intervals at either end of the chassis 700. The ferry assemblies are only arranged at the positions where the wheels of the wheeled cargo pass through, so as to ensure the lightweight of the product. That is, the ferry assemblies adopt a split and disconnected structure. The ferry assemblies are arranged at the positions where the wheeled cargo passes through, and there are no ferry assemblies at other positions. It not only meets the use requirements, but also realizes the lightweight of the vehicle. When the ferry body 100 is inspected and replaced, it only needs to pull out the hinge pin 400 and the limit device 500 to replace the ferry body 100. Since the ferry assembly is a split structure, it is small in size, light in weight, and easy to operate, especially the upper ferry at high altitude.

[0089] For the sake of easy distinction, the ferry assemblies at both ends of the base frame 700 are defined as the first ferry assembly and the second ferry assembly, respectively. There is a height difference between the ferry body 100 of the first ferry assembly and the ferry body 100 of the second ferry assembly, and the height difference is the thickness of the ferry body 100. Fig.13 As shown, with such arrangement, when the vehicles are running on a curved track, the ferry bodies 100 of the two trains will overlap and cross each other, and no interference will occur. When the trains are running on a curved track and the two adjacent vehicles are not in the same straight line, the ferry bodies 100 will not interfere with each other.

[0090] As shown in this application and claims, unless the context clearly indicates an exception, the words "a", "an", "a kind" and / or "the" do not refer to the singular, but also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of clearly identified steps and elements, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.
