Description

Technical Field

[0001] The invention relates to the technical field of escalators, and in particular to a pedal chain for a ring-type moving walkway and a mounting method thereof. Background Art

[0002] In the existing technology, the pedal chain links can only rotate around the front axle and cannot swing sideways or extend to change the pitch. When the staircase transitions from a curved section to a straight section, the inner and outer rings of the pedal chain transition from "length deviation" to "no length deviation". Therefore, the pedal chain is required to be able to realize the variable pitch function, which does not meet the design requirements of the circular sidewalk pedal chain.

[0003] For example, the publication number "CN115367599A" discloses "a step chain for a rotating escalator", including an outer ring step chain and an inner ring step chain, the inner ring arc length of the inner ring step chain is smaller than the outer ring arc length of the outer ring step chain, the outer ring step chain, the shaft chain links of the inner ring step chain cooperate with the step pedal, the outer ring step chain is composed of an outer ring inner chain link, an outer ring transition chain link, an outer ring shaft chain link, an outer ring outer chain link and an outer ring connecting chain link, and the inner ring step chain is composed of an inner ring inner chain link, an inner ring transition chain link, an inner ring shaft chain link, an inner ring outer chain link and an inner ring connecting chain link. However, in actual application, the problem of lateral swing of the chain is solved, but the pitch cannot be adjusted telescopically, and the chain cannot normally enter the ladder leveling section and the transmission sprocket rotating section, which also does not meet the design requirements of the ring-type sidewalk pedal chain. Summary of the invention

[0004] In view of the problem in the prior art mentioned in the background technology that the chain cannot switch normally between the leveling section of the stairway and the rotating section of the transmission sprocket, the present invention provides a pedal chain for a ring-type automatic walkway, which can enable the chain to smoothly switch between the leveling section and the rotating section of the stairway, and the connection can adaptively adjust its own pitch.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions.

[0006] A pedal chain for a ring-type moving walkway, comprising: Coupling chain plate; A butt-jointed chain plate, the butt-jointed chain plate being connected to the coupling chain plate; A wheel axle assembly, the wheel axle assembly is fixedly connected to the coupling chain plate, and the wheel axle assembly includes a front axle; A docking groove is arranged on the docking chain plate, and the front axle is slidably connected in the docking groove.

[0007] In the current market applications, the step escalator has a structure that needs to pass through a rotating section, that is, the structure needs to be set into an arc structure, so the chain design needs to adapt to the arc structure, and in actual applications, the chain can generally only rotate around the front axis, but cannot swing laterally, so fixed arc chains are generally used in the prior art, but this type of chain is not flexible enough and cannot adapt to the flexible switching between the flat section and the rotating section; in the prior art, there are also chains made of stretchable materials, so that the chain can be stretched and deformed, and then can adapt to the flat section and the rotating section, and this type of chain, due to the use of deformable stretchable materials, will also cause the chain to stretch during the force transmission process, the force transmission effect is not as good as the rigid structure, and the structural life of the chain itself is also poorer than that of the rigid connection structure.

[0008] Therefore, in order to solve the problems in the prior art, the present application adopts a method of slidingly connecting the front axle with the docking groove. During use, since the front axle is slidably connected in the docking groove, the front axle can slide relatively in the docking groove. Since the docking chain plate connects the chain plates through the connection between the front axle and the docking groove, and the front axle belongs to the wheel axle assembly fixedly connected to the connecting chain plate, the distance between the chain links can be changed through the relative sliding between the docking groove and the front axle. In the prior art, the connecting chain plate and the docking chain plate are symmetrically arranged on both sides. , and both sides are connected to ensure the uniformity of force transmission, so the butt joint chain plate is connected to the front axle through the butt joint grooves on both sides, so that in the process of lateral swinging, the butt joint grooves on both sides can be displaced to different degrees between the front axle to achieve lateral swinging between the coupling chain plate and the butt joint chain plate to adapt to the arc-shaped rotation section, and because the front axle is only connected to the butt joint groove, during the tensioning process of the butt joint chain plate and the coupling chain plate, the front axle will abut against the side wall of the butt joint groove, so that the butt joint groove and the front axle can achieve force transmission effect through the abutting surface, forming a force transmission effect of a rigid structure. When in the rotation section, since the front axle and the butt joint groove on both sides of the same set of coupling chain plates and butt joint chain plates can move independently, the front axle on one side can abut against the side wall of the butt joint groove, and the front axle on the other side can adaptively move to achieve force transmission effect through the front axle and the butt joint groove in the process of forming lateral swing. Therefore, in the present application, through the above structure, it is possible to simultaneously achieve the rigid force transmission effect between the chain plates, the flexibility of smooth switching between the rotating section and the leveling section, and the ability to maintain stable force transmission on the rotating section.

[0009] As a preferred embodiment, it also includes: A guide member connected to the front axle; A guide docking piece is connected to the docking groove, and the guide docking piece is slidably connected to the guide piece.

[0010] In the present application, a guide member and a guide docking member are provided so that the relative position between the front axle and the docking groove can be fixedly constrained, and at the same time, a guiding effect can be performed during the relative sliding process between the docking groove and the front axle; wherein the guide member and the guide docking member include but are not limited to structures such as a latch and a slide groove, a slider and a slide groove, and the setting position can be changed according to actual usage conditions, for example, the slide groove can be set on the docking groove, and the slide groove can also be set on the front axle, and the connection relationship between the guide member and the guide docking member and the front axle and the docking groove can be an integral molding setting or a split connection setting.

[0011] Preferably, the guide member is a bayonet provided on the front axle, and the guide docking member is a slide groove provided on the docking groove, and the bayonet is slidably connected in the slide groove. The bayonet is provided on the front axle, wherein the bayonet and the front axle are separately provided, and the bayonet is connected to the front axle and connected to the slide groove on the docking groove, so that the front axle can be relatively displaced along the slide groove on the docking groove by the guidance of the bayonet, and at the same time, in a non-swinging state, under the tensioning force of the coupling chain plate and the docking chain plate, the lateral position between the front axle and the docking groove can be limited, thereby ensuring that there is no lateral position between the coupling chain plate and the docking chain plate, and ensuring the stability of force transmission.

[0012] Preferably, the slide slot is provided with an installation opening, and the bayonet can be inserted into the opening and slidably connected in the slide slot. The slide slot is provided with an installation opening, wherein the installation opening enables the bayonet to be smoothly inserted into the slide slot, thereby ensuring assembly efficiency.

[0013] Preferably, a force transmission surface is provided in the docking groove, and when the docking chain plate and the coupling chain plate are tightened against each other, the front axle abuts against the force transmission surface, and an outer convex arc surface is provided on the force transmission surface. When the coupling chain plate and the docking chain plate are tensioned against each other, the front axle will abut against one surface of the docking groove, and this surface is defined as the force transmission surface. The tensioned coupling chain plate and the docking chain plate transmit force through the force transmission surface. At the same time, when the front axle abuts against the force transmission surface, it is the limit displacement state of the front axle in the slide groove. When lateral deflection occurs between the coupling chain plate and the docking chain plate, one of the front axles abuts against the force transmission surface of the docking groove, while the other front axle moves away from the force transmission surface, which will cause the entire front axle to be offset from the center horizontal line. Therefore, in the present application, an outer convex arc is provided on the force transmission surface. surface, so that when the front axle abuts against the force transmission surface, it can still swing along the outer convex arc surface, ensuring the smoothness of the swinging and the abutment effect with the force transmission surface, so that it can adapt to the swinging at various angles without causing stress concentration. At the same time, since the contact area between the front axle and the outer convex arc surface is basically consistent during the swinging process, the force transmission effect can be maintained uniform, so as to avoid sudden changes in the force transmission effect between the coupling chain plate and the docking chain plate, thereby improving stability and providing space for the swinging of the front axle.

[0014] Preferably, a reset member is provided in the docking slot, the reset member connects the front axle and the docking slot, and when the front axle is displaced relative to the docking slot, the reset member generates a reset force in the opposite direction of the front axle. The reset member in the docking slot can reset the front axle in the opposite direction, so that the front axle can always be reset by the reset member during the lateral swinging process, thereby preventing the front axle from being in an unstable state in the docking slot. The reset member includes but is not limited to elastic materials such as springs, elastic blocks, and torsion springs.

[0015] Preferably, a force transmission surface is provided in the docking groove, and when the docking chain plate and the connecting chain plate are tightened in opposite directions, the front axle contacts the force transmission surface, and the docking groove includes a mounting surface arranged opposite to the force transmission surface, and an elastic member is arranged on the mounting surface, and the elastic member is connected to the front axle. The mounting surface and the force transmission surface are the side surfaces of two docking grooves arranged opposite to each other, and by arranging the elastic member on the side surface of the docking groove, the elastic member can push the front axle to abut against the force transmission surface, thereby ensuring that the front axle and the force transmission surface can maintain a continuous and stable abutment effect in a non-swinging state, thereby avoiding the front axle from colliding with the force transmission surface due to the gap between the front axle and the force transmission surface during the movement, thereby ensuring the stability of force transmission. During the lateral swinging of the butt chain plate and the connecting chain plate, since they need to adapt to the change in curvature, the butt chain plate and the connecting chain plate need to produce a deflection, thereby reducing the chain link spacing, so that the front axle on one side will squeeze the elastic part, while the front axle on the other side always maintains contact with the force transmission surface. The front axle on the side of the extruded elastic part is subjected to the extrusion force generated by the connecting chain plate adapting to the arc deformation, and the rebound force formed by the elastic part due to being squeezed, so that the front axle is subjected to force left and right, thereby ensuring the stability of the front axle and the stability of the deflection.

[0016] Preferably, when the coupling chain plate and the butt chain plate are in a non-swinging state, the elastic member presses the front shaft to abut against the force transmission surface. In the non-swinging state, the elastic member presses the front shaft to abut against the force transmission surface, thereby ensuring stable abutment between the butt chain plate and the coupling chain plate, so that a stable force transmission effect can be achieved between each chain plate.

[0017] Preferably, a method for installing a pedal chain comprises the following steps: S1. Install the wheel axle assembly on the connecting chain plate; S2, connect the butt chain plate with the coupling chain plate, and connect the butt groove with the front axle; S3. Place the front axle against the force transmission surface and install an elastic member between the mounting surface and the front axle.

[0018] During the installation process, the wheel axle assembly is first installed, and the front axle set on the coupling chain plate is synchronized with the movement of the coupling chain plate. Subsequently, the docking groove on the docking chain plate is connected to the corresponding front axle, so that the front axle can move relatively in the docking groove, and then the front axle is abutted against the force transmission surface. At this time, the docking chain plate and the coupling chain plate are in a relatively maximum stroke position, and the distance between the front axle and the mounting surface is the farthest. The elastic part is installed to ensure the smoothness of the installation of the elastic part. After the installation of the elastic part, it abuts against the front axle, and a groove or surface that can connect the elastic part is set on the mounting surface and the front axle to ensure the stability of the installation. Since the front axle itself is in a state of abutting the force transmission surface, the front axle will not collide with the force transmission surface during operation, thereby ensuring the stability of operation and the life of the structure.

[0019] Preferably, when the elastic member is in the maximum compression position, the travel of the bayonet in the slide slot does not reach the installation opening of the slide slot. Since the bayonet is installed in the slide slot through the installation opening, the bayonet can also be removed from the slide slot through the installation opening, wherein the bayonet is prevented from falling out of the slide slot by controlling the limit compression position of the elastic member. Since the bayonet is moved to the force transmission surface after the bayonet is installed, there is enough installation clearance between the bayonet and the installation surface to install the elastic member. When the elastic member is installed, the elastic member itself has a limit compression amount. Under this limit compression amount, the bayonet still does not move to the installation opening, thereby ensuring that the bayonet is always moving in the slide slot, and ensuring the connection stability between the butt chain plate and the coupling chain plate.

[0020] The beneficial effects of the present invention are as follows: (1) The chain can smoothly switch between the leveling section and the rotary section of the ladder, and the connection can adaptively adjust its pitch; (2) The sliding connection between the bayonet pin and the slide groove can ensure the running stability of the front axle in the docking groove; (3) It can provide the front axle with a larger swinging space, making the swinging smoother, reducing the limiting effect of the force transmission surface on the front axle, and at the same time ensuring that the force transmission effect between the force transmission surface and the front axle is uniform; (4) It can ensure that the front axle is always in contact with the force transmission surface, so that the butt chain plate and the connecting chain plate can maintain a rigid connection, thereby ensuring the force transmission effect, while reducing impact and ensuring the stability of the front axle.

DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Embodiment 1: like Figure 1 As shown, a pedal chain for a ring-type moving walkway includes: Coupling chain plate 1; The butt-jointed chain plate 2 is connected to the coupling chain plate 1; The wheel axle assembly 3 is fixedly connected to the coupling chain plate 1, and the wheel axle assembly 3 includes a front axle 31; The docking groove 21 is arranged on the docking chain plate 2 , and the front axle 31 is slidably connected in the docking groove 21 .

[0029] In current market applications, step escalators have structures that need to pass through a rotating section, that is, the structure needs to be set into an arc structure, so the chain design needs to adapt to the arc structure, and in actual applications, the chain can generally only rotate around the front axis 31, but cannot swing laterally, so fixed arc chains are generally used in the prior art, but this type of chain is not flexible enough and cannot adapt to the flexible switching between the flat section and the rotating section; in the prior art, there are also chains made of stretchable materials, so that the chain can be stretched and deformed, and then can adapt to the flat section and the rotating section, and this type of chain, due to the use of deformable stretchable materials, will also cause the chain to stretch during the force transmission process, the force transmission effect is not as good as the rigid structure, and the structural life of the chain itself is also poorer than that of the rigid connection structure.

[0030] Therefore, in view of the problems in the prior art, the present embodiment adopts a method of slidingly connecting the front axle 31 with the docking groove 21. During use, since the front axle 31 is slidably connected in the docking groove 21, the front axle 31 can slide relatively in the docking groove 21. Since the docking chain plate 2 is connected to the chain plates through the connection between the front axle and the docking groove 21, and the front axle 31 belongs to the wheel axle assembly 3 fixedly connected to the connecting chain plate 1, the distance between the chain links can be changed between the connecting chain plate 1 and the docking chain plate 2 through the relative sliding between the docking groove 21 and the front axle 31. In the prior art, the connecting chain plate, i.e., the docking chain plate 2, is symmetrically arranged on both sides. The butt joint chain plate 2 is connected to the front axle 31 through the butt joint grooves 21 on both sides, so that during the lateral swinging, the lateral swinging between the coupling chain plate 1 and the butt joint chain plate 2 can be realized through the displacement of different degrees between the butt joint grooves 21 on both sides and the front axle 31 to adapt to the arc-shaped rotating section, and because the front axle 31 is only connected to the butt joint groove 21, during the tensioning of the butt joint chain plate 2 and the coupling chain plate 1, the front axle 31 will abut against the side wall of the butt joint groove 21, so that the butt joint groove 21 and the front axle 31 can transmit force through the abutting surface, forming a force transmission effect of a rigid structure. When in the rotating section, since the front axle 31 and the docking groove 21 on both sides of the same set of coupling chain plates 1 and docking chain plates 2 can move independently, the front axle 31 on one side can abut against the side wall of the docking groove 21, and the front axle 31 on the other side can move adaptively to achieve the force transmission effect through the front axle 31 and the docking groove 21 during the lateral deflection. Therefore, in this embodiment, through the above structure, the rigid force transmission effect between the chain plates, the flexibility of smooth switching between the rotating section and the leveling section, and the effect of maintaining stable force transmission on the rotating section can be achieved at the same time.

[0031] like Figure 1 As shown, it also includes: A guide member connected to the front axle 31; The guide docking piece is connected to the docking groove 21, and the guide docking piece is slidably connected to the guide piece.

[0032] In this embodiment, a guide member and a guide docking member are provided so that the relative position between the front axle 31 and the docking groove 21 can be fixedly constrained, and a guiding effect can be performed during the relative sliding process between the docking groove 21 and the front axle 31; wherein the guide member and the guide docking member include but are not limited to structures such as a latch and a slide groove 211, a slider and a slide groove 211, and the setting position can be changed according to actual usage conditions, for example, the slide groove 211 can be set on the docking groove 21, and the slide groove 211 can also be set on the front axle 31, and the connection relationship between the guide member and the guide docking member and the front axle 31 and the docking groove 21 can be an integrally formed setting or a split connection setting.

[0033] like Figure 2 , 3 As shown in 4, the guide member is a bayonet 311 arranged on the front axle 31, and the guide docking member is a slide groove 211 arranged on the docking groove 21, and the bayonet 311 is slidably connected in the slide groove 211. The bayonet 311 is arranged on the front axle 31, wherein the bayonet 311 and the front axle 31 are arranged separately, and the bayonet 311 needs to be connected into the front axle 31 and connected with the slide groove 211 on the docking groove 21, so that the front axle 31 can be relatively displaced along the slide groove 21 on the docking groove 21 by the guidance of the bayonet 311, and at the same time, in the non-swinging state, under the tensioning force of the coupling chain plate 1 and the docking chain plate 2, the lateral position between the front axle 31 and the docking groove 21 can be limited, so as to ensure that there is no lateral position between the coupling chain plate 1 and the docking chain plate 2, and ensure the stability of force transmission.

[0034] like Figure 4 As shown, the slide slot 211 is provided with an installation opening 212, and the bayonet 311 can penetrate the opening and slide into the slide slot 211. The installation opening 212 is provided on the slide slot 211, wherein the installation opening 212 can make the bayonet 311 smoothly snap into the slide slot 211, thereby ensuring assembly efficiency.

[0035] like Figure 5As shown, a force transmission surface 213 is provided in the docking groove 21. When the docking chain plate 2 and the coupling chain plate 1 are tensioned against each other, the front axle 31 abuts against the force transmission surface 213, and an outer convex arc surface 214 is provided on the force transmission surface 213. When the coupling chain plate 1 and the docking chain plate 2 are tensioned against each other, the front axle 31 will abut against one surface of the docking groove 21, which is defined as the force transmission surface 213. The tensioned coupling chain plate 1 and the docking chain plate 2 transmit force through the force transmission surface 213. At the same time, when the front axle 31 abuts against the force transmission surface 213, it is the limit displacement state of the front axle 31 in the slide groove 211. When a lateral deflection occurs between the coupling chain plate 1 and the docking chain plate 2, one of the front axles 31 abuts against the force transmission surface 213 of the docking groove 21, while the other front axle 31 moves away from the force transmission surface 213, which will cause the entire front axle 31 to be offset from the center horizontal line. Therefore, in this embodiment, An outer coated arc surface is provided on the force transmission surface 213, so that when the front axle 31 abuts against the force transmission surface 213, it can still swing along the outer convex arc surface 214, ensuring the smoothness of the swinging and the abutment effect with the force transmission surface 213, thereby being able to adapt to swinging at various angles without causing stress concentration. At the same time, since the contact area between the front axle 31 and the outer convex arc surface 214 remains basically consistent during the swinging process, the force transmission effect can be maintained uniform, thereby avoiding sudden changes in the force transmission effect between the coupling chain plate 1 and the docking chain plate 2, thereby improving stability and providing space for the swinging of the front axle 31.

[0036] like Figure 4 , 5 As shown, a reset member is provided in the docking groove 21, and the reset member connects the front axle 31 and the docking groove 21. When the front axle 31 is displaced relative to the docking groove 21, the reset member generates a reset force in the opposite direction to the front axle 31. A force transmission surface 213 is provided in the docking groove 21. When the docking chain plate 2 and the connecting chain plate 1 are tightened in opposite directions, the front axle 31 contacts the force transmission surface 213. The docking groove 21 includes a mounting surface 215 arranged opposite to the force transmission surface 213. The mounting surface 215 is provided with an elastic member 4, and the elastic member 4 is connected to the front axle 31. In this embodiment, the reset member is an elastic member.

[0037] The mounting surface 215 and the force transmission surface 213 are the side surfaces of two oppositely arranged docking grooves 21. By arranging the elastic member 4 on the side surface of the docking groove 21, the elastic member 4 can push the front axle 31 to abut against the force transmission surface 213, thereby ensuring that in a non-swinging state, a continuous and stable abutment effect can be maintained between the front axle 31 and the force transmission surface 213, thereby avoiding collision and bumping between the front axle 31 and the force transmission surface 213 during movement due to a gap between the front axle 31 and the force transmission surface 213, thereby ensuring the stability of force transmission. During the lateral swinging of the butt-jointed chain plate 2 and the connecting chain plate 1, since they need to adapt to the change in curvature, the butt-jointed chain plate 2 and the connecting chain plate 1 need to produce a deflection, thereby reducing the chain link spacing, so that the front axle 31 on one side will squeeze the elastic member 4, while the front axle 31 on the other side always maintains contact with the force transmission surface 213. The front axle 31 on the side of the extruded elastic member 4 is subjected to the extrusion force generated by the connecting chain plate 1 adapting to the arc deformation, and the rebound force formed by the elastic member 4 due to being squeezed, so that the front axle 31 is subjected to force left and right, thereby ensuring the stability of the front axle 31 and the stability of the deflection.

[0038] like Figure 5 As shown, when the coupling chain plate 1 and the butt chain plate 2 are in a non-swinging state, the elastic member 4 squeezes the front shaft 31 to abut against the force transmission surface 213. In the non-swinging state, the elastic member 4 squeezes the front shaft 31 to abut against the force transmission surface 213, thereby ensuring stable abutment between the butt chain plate 2 and the coupling chain plate 1, so that a stable force transmission effect can be achieved between each chain plate.

[0039] Embodiment 2: A method for installing a pedal chain in this embodiment includes the following steps: S1, install the wheel shaft assembly 3 on the connecting chain plate 1; S2, connecting the butt chain plate 2 with the coupling chain plate 1, and connecting the butt groove 21 with the front axle 31; S3 . Place the front axle 31 against the force transmission surface 213 , and install the elastic member 4 between the installation surface 215 and the front axle 31 .

[0040] During the installation process, the wheel axle assembly 3 is first installed, and the front axle 31 set on the connecting chain plate 1 is synchronized with the movement of the connecting chain plate 1. Subsequently, the docking groove 21 on the docking chain plate 2 is connected to the front axle 31 accordingly, so that the front axle 31 can move relatively in the docking groove 21, and then the front axle 31 is abutted against the force transmission surface 213. At this time, the docking chain plate 2 and the connecting chain plate 1 are in a relatively maximum stroke position, and the distance between the front axle 31 and the mounting surface 215 is the farthest. The elastic member 4 is installed to ensure the smoothness of the installation of the elastic member 4. After the installation is completed, the elastic member 4 abuts against the front axle 31, and a groove or surface that can connect the elastic member 4 is set on the mounting surface 215 and the front axle 31, so as to ensure the stability of the installation. Since the front axle 31 itself is in a state of abutting the force transmission surface 213, the front axle 31 will not collide with the force transmission surface 213 during operation, thereby ensuring the stability of operation and the life of the structure.

[0041] When the elastic member 4 is at the maximum compression position, the travel of the bayonet 311 in the slide slot 211 does not reach the installation opening 212 of the slide slot 211. Since the bayonet 311 is installed in the slide slot 211 through the installation opening 212, the bayonet 311 can also be removed from the slide slot 211 through the installation opening 212, wherein the bayonet 311 is prevented from falling out of the slide slot 211 by controlling the limit compression position of the elastic member 4. Since the bayonet 311 is moved to the force transmission surface 213 after the bayonet 311 is installed, there is enough installation clearance between the bayonet 311 and the installation surface 215 to install the elastic member 4. When the elastic member 4 is installed, the elastic member 4 itself has a limit compression amount. Under this limit compression amount, the bayonet 311 still does not move to the installation opening 212, thereby ensuring that the bayonet 311 is always moving in the slide slot 211, and ensuring the connection stability between the butt chain plate 2 and the coupling chain plate 1.

[0042] Furthermore, the above-mentioned installation method in this embodiment has the following technical features, including: Coupling chain plate 1; A butt chain plate 2 connected to the coupling chain plate 1; A wheel axle assembly 3 fixedly connected to the coupling chain plate 1, the wheel axle assembly 3 includes a front axle 31; A docking groove 21 is provided on the docking chain plate 2, and the front shaft 31 is slidably connected in the docking groove 21; A guide member connected to the front axle 31; A guide docking piece connected to the docking groove 21, wherein the guide docking piece is slidably connected to the guide piece; The guide member in this embodiment is a bayonet 311, which is disposed on the front shaft 31, and the guide docking member is a slide groove 211 disposed on the docking groove 21, in which the bayonet 311 is slidably connected. The slide slot 211 is provided with a mounting opening 212 , and the latch 311 can penetrate into the opening and be slidably connected in the slide slot 211 .

[0043] In this embodiment, the front axle 31 is slidably connected to the docking groove 21. During use, since the front axle 31 is slidably connected in the docking groove 21, the front axle 31 can slide relatively in the docking groove 21; and since the docking chain plate 2 connects the chain plates through the connection between the front axle and the docking groove 21, and the front axle 31 belongs to the wheel axle assembly 3 fixedly connected to the coupling chain plate 1, the coupling chain plate 1 and the docking chain plate 2 can change the chain link spacing through the relative sliding between the docking groove 21 and the front axle 31.

[0044] The connecting chain plate, i.e., the docking chain plate 2, is symmetrically arranged on both sides, and both sides are connected to ensure uniform force transmission. Therefore, the docking chain plate 2 is connected to the front axle 31 through the docking grooves 21 on both sides, so that during the lateral swinging, the lateral swinging between the connecting chain plate 1 and the docking chain plate 2 can be achieved through different degrees of displacement between the docking grooves 21 on both sides and the front axle 31 to adapt to the arc-shaped rotating section. Moreover, since the front axle 31 is only connected to the docking groove 21, during the tensioning of the docking chain plate 2 and the connecting chain plate 1, the front axle 31 will abut against the side wall of the docking groove 21, so that the docking groove 21 and the front axle 31 can transmit force through the abutting surface, thereby forming a force transmission effect of a rigid structure. When in the rotating section, since the front axle 31 and the docking groove 21 on both sides of the same set of coupling chain plates 1 and docking chain plates 2 can move independently, the front axle 31 on one side can abut against the side wall of the docking groove 21, and the front axle 31 on the other side can move adaptively to achieve the force transmission effect through the front axle 31 and the docking groove 21 during the lateral deflection. Therefore, in this embodiment, through the above structure, the rigid force transmission effect between the chain plates, the flexibility of smooth switching between the rotating section and the leveling section, and the effect of maintaining stable force transmission on the rotating section can be achieved at the same time.

[0045] In this embodiment, a guide member and a guide docking member are provided so that the relative position between the front axle 31 and the docking groove 21 can be fixedly constrained, and a guiding effect can be performed during the relative sliding process between the docking groove 21 and the front axle 31; wherein the guide member and the guide docking member include but are not limited to structures such as a latch and a slide groove 211, a slider and a slide groove 211, and the setting position can be changed according to actual usage conditions, for example, the slide groove 211 can be set on the docking groove 21, and the slide groove 211 can also be set on the front axle 31, and the connection relationship between the guide member and the guide docking member and the front axle 31 and the docking groove 21 can be an integrally formed setting or a split connection setting.

[0046] A latch 311 is provided on the front axle 31, wherein the latch 311 and the front axle 31 are separated. The latch 311 needs to be connected to the front axle 31 and connected to the slide groove 211 on the docking groove 21, so that the front axle 31 can be relatively displaced along the slide groove 21 on the docking groove 21 by the guidance of the latch 311. At the same time, in a non-swinging state, under the tension of the coupling chain plate 1 and the docking chain plate 2, the lateral position between the front axle 31 and the docking groove 21 can be limited, thereby ensuring that there is no lateral position between the coupling chain plate 1 and the docking chain plate 2, and ensuring the stability of force transmission. An installation opening 212 is provided on the slide groove 211, wherein the installation opening 212 can make the latch 311 smoothly inserted into the slide groove 211, ensuring the efficiency of assembly.

[0047] In this embodiment, a force transmission surface 213 is provided in the docking groove 21. When the docking chain plate 2 and the coupling chain plate 1 are pulled back to back, the front shaft 31 abuts against the force transmission surface 213, and an outer convex arc surface 214 is provided on the force transmission surface 213. When the docking chain plate 2 and the coupling chain plate 1 are pulled back to back, the front shaft 31 contacts the force transmission surface 213. The docking groove 21 includes a mounting surface 215 arranged opposite to the force transmission surface 213, and an elastic member 4 is provided on the mounting surface 215, and the elastic member 4 is connected to the front shaft 31. When the coupling chain plate 1 and the docking chain plate 2 are in a non-swinging state, the elastic member 4 squeezes the front shaft 31 to abut against the force transmission surface 213.

[0048] When the connecting chain plate 1 and the docking chain plate 2 are tensioned with each other, the front axle 31 will abut against a surface of the docking groove 21, which is defined as a force transmission surface 213. The tensioned connecting chain plate 1 and the docking chain plate 2 transmit force through the force transmission surface 213. At the same time, when the front axle 31 abuts against the force transmission surface 213, it is the limit displacement state of the front axle 31 in the slide groove 211. When lateral deflection occurs between the connecting chain plate 1 and the docking chain plate 2, one of the front axles 31 abuts against the force transmission surface 213 of the docking groove 21, while the other front axle 31 moves away from the force transmission surface 213, which will cause the entire front axle 31 to be offset from the center horizontal line. Therefore, in this embodiment, An outer coated arc surface is provided on the force transmission surface 213, so that when the front axle 31 abuts against the force transmission surface 213, it can still swing along the outer convex arc surface 214, ensuring the smoothness of the swinging and the abutment effect with the force transmission surface 213, thereby being able to adapt to swinging at various angles without causing stress concentration. At the same time, since the contact area between the front axle 31 and the outer convex arc surface 214 remains basically consistent during the swinging process, the force transmission effect can be maintained uniform, thereby avoiding sudden changes in the force transmission effect between the coupling chain plate 1 and the docking chain plate 2, thereby improving stability and providing space for the swinging of the front axle 31.

[0049] The mounting surface 215 and the force transmission surface 213 are the side surfaces of two oppositely arranged docking grooves 21. By arranging the elastic member 4 on the side surface of the docking groove 21, the elastic member 4 can push the front axle 31 to abut against the force transmission surface 213, thereby ensuring that in a non-swinging state, a continuous and stable abutment effect can be maintained between the front axle 31 and the force transmission surface 213, thereby avoiding collision and bumping between the front axle 31 and the force transmission surface 213 during movement due to a gap between the front axle 31 and the force transmission surface 213, thereby ensuring the stability of force transmission. During the lateral swinging of the butt joint chain plate 2 and the coupling chain plate 1, the butt joint chain plate 2 and the coupling chain plate 1 need to produce a deflection due to the need to adapt to the change in the arc, thereby reducing the distance between the chain links, so that the front axle 31 on one side will squeeze the elastic member 4, while the front axle 31 on the other side always maintains contact with the force transmission surface 213. The front axle 31 on the side of the squeezed elastic member 4 is subjected to the squeezing force generated by the coupling chain plate 1 adapting to the arc deformation, and the rebound force formed by the elastic member 4 due to being squeezed, so that the front axle 31 is subjected to force left and right, thereby ensuring the stability of the front axle 31 and the stability of the deflection. In the non-swinging state, the elastic member 4 squeezes the front axle 31 to abut the force transmission surface 213, thereby ensuring the stable contact between the butt joint chain plate 2 and the coupling chain plate 1, so that a stable force transmission effect can be achieved between each chain plate.
