DETAILED DESCRIPTION

[0039] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0040] Referring to FIG. 1 , FIG. 1 shows a schematic diagram of the structure of a transport system 1 in an embodiment of the present application. The transport system 1 provided in an embodiment of the present application includes a transport device 10, an escalator device 20, and a traction device 30. The transport device 10 is used to carry materials. The escalator device 20 is used to cooperate with the transport device 10 to transport materials to a high place. The traction device 30 is used to traction the transport device 10 to carry the transport device 10 onto the escalator device 20, or to transport the transport device 10 away from the escalator device 20.

[0041] Specifically, as shown in FIG2 , the transport device 10 includes a frame device 100 and a load-bearing assembly 200. The frame device 100 includes a wheel suspension 110 and a width adjustment assembly 120. The load-bearing assembly 200 is connected to the wheel suspension 110, which may be connected by welding, plugging, screwing or the like, or may be an integral arrangement. The wheel suspension 110 includes a telescopic shaft assembly 111. The telescopic shaft assembly 111 is provided with a first end 110a and a second end 110b. The first end 110a and the second end 110b are arranged relative to each other along the width direction X of the wheel suspension, and the spacing between the first end 110a and the second end 110b in the width direction X is adjustable. Figure 3 as well as Figure 4 As shown, the width adjustment assembly 120 includes a force-bearing member 121 and a rotating assembly 122 .

[0042] The force-bearing member 121 is in transmission connection with the rotating assembly 122, and the rotating assembly 122 includes a rotating body 1221, a first connecting rod 1222, and a second connecting rod 1223. The force-bearing member 121 is used to rotate the rotating body 1221 under the action of an external force, and the rotating body 1221 is provided with a third end 122a and a fourth end 122b, and the third end 122a and the fourth end 122b are arranged at intervals, the first end 110a is rotatably connected to one end of the first connecting rod 1222, and the third end 122a is rotatably connected to the other end of the first connecting rod 1222. The second end 110b is rotatably connected to one end of the second connecting rod 1223, and the fourth end 122b is rotatably connected to the other end of the second connecting rod 1223.

[0043] It can be understood that the force-bearing member 121 is used to withstand the external force and convert the external force into a rotational force to drive the rotating body 1221, so that the rotating body 1221 drives the third end 122a and the fourth end 122b to rotate. At this time, the distance between the third end 122a and the fourth end 122b in the width direction X is adjustable (such as the connecting straight line between the third end 122a and the fourth end 122b, from a diameter straight line parallel to the width direction X to a diameter straight line perpendicular to the width direction X), thereby causing the first connecting rod 1222 and the second connecting rod 1223 to rotate, thereby driving the distance between the first end 110a and the second end 110b to be adjustable, and finally realizing the adjustable frame spacing of the frame device, so that the width of the frame device 100 can adapt to the different width sizes of the escalator trusses on different escalator devices 20, enriching the transportation scenarios of the frame device 100 in different escalator devices 20. Furthermore, the cooperation between the first end 110a and the third end 122a, and the cooperation between the second end 110b and the fourth end 122b, are equivalent to two connecting rod assemblies. Using the connecting rod assembly as a transmission method is conducive to labor saving and precise transmission.

[0044] It should be noted that the first end 110a and the second end 110b may be disposed on the wheel assembly 113, so as to adjust the spacing of the wheel suspension 110 by adjusting the spacing of the wheel assembly 113. The first end 110a and the second end 110b may also be disposed on other frame members of the wheel suspension 110, which are not limited here.

[0045] In some embodiments, in combination Figure 5 as well as Figure 6 As shown, the wheel suspension 110 includes a support frame 112, a wheel assembly 113 and a telescopic shaft assembly 111. The wheel assembly 113 is arranged on the support frame 112, the telescopic shaft assembly 111 is telescopically arranged on the support frame 112 (the telescopic shaft assembly 111 may be embedded between the support frames 112 to directly adjust the width of the support frame 112), and the telescopic shaft assembly 111 includes a first telescopic shaft 1111 and a second telescopic shaft 1112 that are relatively spaced apart along the width direction X. The first end 110a is arranged at one end of the first telescopic shaft 1111, and the second end 110b is arranged at one end of the second telescopic shaft 1112. The force-bearing member 121 is driven by an external force to drive the rotating assembly 122 to rotate, so that the spacing between the first telescopic shaft 1111 and the second telescopic shaft 1112 is adjustable.

[0046] It can be understood that, in the embodiment, the wheel assembly 113 is used to drive the support frame 112 to move to the escalator device 20 or move away from the escalator device 20. The telescopic shaft assembly 111 can adjust the width dimension of the support frame 112 in the width direction X. In this way, different from directly adjusting the width of the wheel assembly 113, adjusting on the telescopic shaft assembly 111 is conducive to reducing interference with the wheel assembly 113, thereby improving the connection strength of the wheel assembly 113, reducing the shaking of the wheel assembly 113 in the width direction X, and then improving the transportation stability of the wheel assembly 113 during transportation.

[0047] Specifically, the wheel assembly 113 may include a first roller and a second roller, and the first roller and the second roller are arranged relatively spaced apart along the width direction X. In one example, the first roller and the second roller may be universal wheels.

[0048] It should be noted that the number of wheel assemblies 113 can be one or more, and no further limitation is imposed herein.

[0049] In a specific embodiment, see FIG. 2 and Figure 4 The wheel suspension 110 includes at least two wheel assemblies 113. Thus, the arrangement of at least two wheel assemblies is conducive to increasing the force bearing area of ​​the wheel suspension 110 during transportation, thereby improving the movement stability of the frame device 100 in transporting materials and optimizing the transportation performance.

[0050] Furthermore, the wheel suspension 110 includes a first wheel assembly 1131 and a second wheel assembly 1132. The support frame 112 is provided with a first side 112a and a second side 112b relatively along the length direction Y of the wheel suspension 110. The first wheel assembly 1131 is provided close to the first side 112a, and the second wheel assembly 1132 is provided close to the second side 112b. In this way, by providing the first wheel assembly 1131 close to the first side 112a and the second wheel assembly 1132 close to the second side 112b, the wheel suspension 110 can keep the center of gravity balanced in the length direction Y as much as possible during the movement, thereby improving the movement stability of the wheel suspension 110.

[0051] In addition, in some embodiments, Figures 5 and 6 The wheel suspension 110 includes a first telescopic shaft assembly 111a and a second telescopic shaft assembly 111b, which are arranged at intervals Y along the length direction of the wheel suspension 110. The first telescopic shaft assembly 111a is arranged close to the first side 112a, and the second telescopic shaft assembly 111b is arranged close to the second side 112b. The width adjustment assembly 120 is arranged one-to-one with the telescopic shaft assembly 111.

[0052] Based on this, the wheel suspension 110 is provided with at least two telescopic shaft assemblies 111, and the telescopic shaft assemblies 111 are arranged one-to-one with the width adjustment assemblies 120, so that the force area of ​​the wheel suspension 110 during width adjustment can be increased, making the wheel suspension 110 more stable during width adjustment and more labor-saving to operate.

[0053] In one embodiment, Figure 4 as well as Figure 5 In order to facilitate the control of the frame device 100, the frame device 100 may also be provided with a direction control component 160, which may be, but not limited to, a direction control component 160, a steering wheel, etc. The direction control component 160 is used to control the steering of the wheel assembly 113 to assist the frame device 100 in turning.

[0054] In some embodiments, such as Figure 5 As shown, the rotating assembly 122 includes a rotating body 1221, a first connecting arm 1224 and a second connecting arm 1225. The rotating body 1221 may be a turntable or the like. The first connecting arm 1224 and the second connecting arm 1225 are connected to different positions on the circumference of the rotating body 1221 (e.g., the first connecting arm 1224 and the second connecting arm 1225 may be symmetrically arranged on the rotating body). The third end 122a is arranged at an end of the first connecting arm 1224 that is away from the rotating body 1221, and the fourth end 122b is arranged at an end of the second connecting arm 1225 that is away from the rotating body 1221.

[0055] For ease of understanding, the cooperation principle between the rotating assembly 122 and the wheel suspension 110 according to an embodiment is described below.

[0056] When it is necessary to increase the width dimension of the frame device 100, the force-bearing member 121 can be pushed along the first direction, thereby driving the rotation of the rotating body 1221, so that the third end 122a and the fourth end 122b rotate to push out the first connecting rod 1222 and the second connecting rod 1223 respectively, so that the first end 110a and the second end 110b move away from each other, thereby driving the spacing between the first end 110a and the second end 110b to change from the first spacing to the second spacing, so as to increase the spacing of the wheel suspension 110 in the width direction X, so that a wider escalator device 20 can be used.

[0057] When the distance of the frame device 100 needs to be narrowed, the force-bearing member 121 can be moved along the second direction (in one example, the second direction can be opposite to the first direction) to drive the rotating body 1221 to rotate in the opposite direction, so that the third end 122a and the fourth end 122b rotate to pull the first connecting rod 1222 and the second connecting rod 1223, so that the first end 110a and the second end 110b are close to each other, and then the spacing between the first end 110a and the second end 110b is changed from the second spacing to the first spacing, so as to reduce the spacing of the wheel suspension 110 in the width direction X, thereby being able to adapt to the escalator equipment 20 of narrower size.

[0058] In this way, different from using a rotating shaft or the like as the rotating body 1221 to realize the rotation of the first connecting arm 1224 and the second connecting arm 1225, the rotating body 1221 and the first connecting arm 1224 and the first connecting arm 1224 rotate, and the force-bearing area of ​​the rotating body 1221 and the force-bearing member 121 is larger, and the connection strength between the two is higher, which is conducive to optimizing the transmission stability of the rotating body 1221, and then improving the motion stability of the frame device 100 during the width adjustment process. Further, in an example, the first connecting arm 1224 and the second connecting arm 1225 are symmetrically arranged on the rotating body 1221, so that when the first connecting arm 1224 and the second connecting arm 1225 respectively drive the first connecting rod 1222 and the second connecting rod 1223, it can be ensured that the first end 110a and the second end 110b can move synchronously in the direction of approaching or moving away from each other, thereby ensuring the motion consistency of the width adjustment process of the frame device 100.

[0059] It should be noted that the force-bearing member 121 drives the rotating assembly 122 to rotate in a flexible transmission or a rigid transmission, and no excessive restrictions are imposed here.

[0060] Further, in other embodiments, the force-bearing member 121 is rotatably connected to the rotating body 1221 through an elastic member, and the rotating body 1221 can at least switch between a first rotation position and a second rotation position. When the force-bearing member 121 is acted upon by an external force so that the rotating body 1221 is in the first rotation position, the force-bearing member 121 compresses the elastic member to drive the rotating body 1221 to rotate, and then drives the first end 110a and the second end 110b to approach each other through the first connecting rod 1222 and the second connecting rod 1223. When the above-mentioned external force applied by the force-bearing member 121 to the rotating body 1221 is reduced or released (even if the rotating body 1221 is in the first rotation position), the elastic member resets and drives the rotating body 1221 to rotate to the second rotation position, and then drives the first end 110a and the second end 110b to move away from each other through the first connecting rod 1222 and the second connecting rod 1223. In this way, by setting the elastic member, the transmission speed of the rotational cooperation between the force-bearing member 121 and the rotating body 1221 can be accelerated, and the rotating body 1221 can be quickly reset, which is beneficial to improving the efficiency of width adjustment of the frame device 100. In addition, the operating feel of the force-bearing member 121 can be improved, and when the rotating body 1221 is reset, the effort spent by the operator on the force-bearing member 121 can be reduced, which is beneficial to saving effort.

[0061] In one embodiment, Figure 4 as well as Figure 6 , the force-bearing member 121 and the rotating assembly 122 adopt a flexible transmission method. Specifically, in one example, the rotating assembly 122 also includes a third connecting arm 1226 and a flexible transmission member 1227. The force-bearing member 121 is used to pull the flexible transmission member 1227 under the action of an external force, one end of the third connecting arm 1226 is connected to the rotating body 1221, and is spaced apart from the first connecting arm 1224 and the second connecting arm 1225. One end of the flexible transmission member 1227 is connected to the third connecting arm 1226, and the other end of the flexible transmission member 1227 is transmission-connected to the force-bearing member 121. That is, the force-bearing member 121 is used to pull the flexible transmission member 1227 under the action of an external force, and the flexible transmission member 1227 drives the rotating body 1221 to rotate through the third connecting arm 1226.

[0062] It can be understood that the rotation vector of the rotating body 1221 depends on the transmission distance between the force-bearing member 121 and the rotating assembly 122. Different from the use of a rigid member (such as a rotating shaft) as a transmission method between the rotating assembly 122 and the force-bearing member 121, the transmission distance between the force-bearing member 121 and the rotating body 1221 is narrower, and the rotation vector of the rotating body 1221 is smaller, so that the width movement spacing change of the frame device 100 is smaller (that is, the difference between the first spacing and the second spacing is smaller), which in turn makes the adjustable width range of the frame device 100 smaller, and the frame device 100 is adapted to fewer scenarios of the escalator equipment 20.

[0063] In the present embodiment, a flexible transmission member 1227 (such as a rope, a chain, etc.) is used as a transmission member between the force-bearing member 121 and the rotating body 1221, so that the transmission distance between the force-bearing member 121 and the rotating body 1221 can be increased, thereby making the rotation vector of the rotating body 1221 larger, and then the range of the width adjustment distance of the vehicle frame device 100 can be increased (that is, the difference between the first spacing and the second spacing is larger), and the frame device 100 of different width sizes can be adjusted to adapt to escalator equipment 20 of different width sizes, thereby enriching the use scenarios of the frame device 100.

[0064] Furthermore, the flexible transmission member 1227 can be arranged on the frame device 100 in a retractable manner, so as not to occupy too much space of the frame device 100, thereby ensuring the carrying space of the material. At the same time, through the transmission connection between the third connecting arm 1226 and the flexible transmission member 1227, the rotation interference of the flexible transmission member 1227 on the first connecting arm 1224 and the second connecting arm 1225 is reduced, thereby improving the width adjustment stability of the frame device 100.

[0065] In addition, in one example, the connection line between the third connecting arm 1226 and the rotating body 1221 is on the axis of the rotating body 1221 , which is helpful to ensure the rotation balance of the rotating body 1221 during the rotation process.

[0066] In order to facilitate the operator to pull the rotating body 1221, in other embodiments, as shown in FIG. 2, the force-bearing member 121 includes a mounting seat 1211 and a pull rod 1212, the pull rod 1212 is connected to the mounting seat 1211, and one end of the pull rod 1212 is transmission-connected to one end of the flexible transmission member 1227. The mounting seat 1211 is provided with an active cavity along a preset direction, and one end of the flexible transmission member 1227 is slidably disposed in the active cavity. Among them, the active cavity is extended along a preset direction (such as an obliquely upward direction in the direction shown in the figure). Under the action of an external force, the pull rod 1212 has a motion vector along a preset direction (such as an obliquely upward direction in the figure), so that the pull rod 1212 drives the flexible transmission member 1227 to slide and cooperate in the active cavity, so that the flexible transmission member 1227 pulls the rotating body 1221 to rotate.

[0067] It is understandable that when the rotating body 1221 is pulled and rotated by the force-bearing member 121, the rotating body 1221 has a horizontal movement component and a vertical movement component. If the force-bearing member 121 is directly connected to the rotating body 1221, the force-bearing member 121 also needs to have a horizontal movement component and a vertical movement component. Accordingly, the operator needs to shake the force-bearing member 121 to make it have a horizontal movement component and a vertical movement component, which leads to inconvenience in operation. In this embodiment, the pull rod 1212 drives the traction transmission member to slide in the movable cavity. On the one hand, the operator's operation of the pull rod 1212 can be a directional movement to pull or release the flexible transmission member 1227. The directional movement refers to a rotational movement or a sliding movement along a preset direction. The directional operation improves the operator's operating convenience and facilitates the operator to control the transmission distance of the flexible transmission member 1227, thereby improving the control accuracy of the rotation vector of the rotating body 1221.

[0068] In combination with any embodiment of the above-mentioned mounting seat 1211 and the pull rod 1212, the pull rod 1212 is provided with a first locking portion. The mounting seat 1211 is provided with at least two locking matching portions arranged at intervals, and the first locking portion is used to engage and lock with the locking matching portion, so that the force-bearing member 121 drives the flexible transmission member 1227 to lock the mounting seat 1211.

[0069] In this way, the first locking portion and the locking matching portion are locked and matched, which can improve the fixing effect of the flexible transmission member 1227 on the mounting seat 1211, and prevent the flexible transmission member 1227 from slipping and driving the rotating body 1221 to rotate and reset, thereby affecting the width adjustment stability of the frame device 100; and there is no need for the operator to manually lock the flexible transmission member 1227, which facilitates the operation of the frame device 100 during width adjustment.

[0070] Furthermore, based on the fact that the mounting seat 1211 is provided with at least two locking fitting parts arranged at intervals, the pull rod 1212 drives the flexible transmission member 1227 to be locked in at least two positions (the position of the locking fitting parts can be designed according to the width size of the escalator device 20). By setting the number and spacing of the locking fitting parts, the width adjustment amount of the frame device 100 is controlled, and the pull rod 1212 is locked in different locking fitting parts, which is conducive to realizing the graded adjustment of the width of the frame device 100, and further enables the width of the frame device 100 to adapt to the width of different escalator devices 20 and facilitate operation.

[0071] In addition, in other embodiments, Figure 4 as well as Figure 6As shown, the force-bearing member 121 is used to drive at least two rotating components 122 to rotate under the action of external force, so that the force-bearing member 121 drives at least two rotating components 122 to rotate synchronously, so as to drive the telescopic shaft component 111 to telescopically move. Specifically, the force-bearing member 121 also includes a telescopic movable member, and the frame device 100 includes at least two width adjustment components 120120. At least two flexible transmission members 1227 are connected to the telescopic movable member 1213, so that the telescopic movable member 1213 drives at least two flexible transmission members 1227 to pull the corresponding rotating body 1221 to rotate.

[0072] In one example, the frame device 100 includes a first rotating body and a second rotating body, and includes a first flexible transmission member 1227a and a second flexible transmission member 1227b, one end of the first flexible transmission member 1227a and one end of the second flexible transmission member 1227b are both connected to one end of the telescopic movable member, the other end of the first flexible transmission member 1227a is connected to the first rotating body, and the other end of the second flexible transmission member 1227b is connected to the second rotating body. The pull rod 1212 is in transmission cooperation with the telescopic movable member (wherein the pull rod 1212 and the telescopic movable member can be rotationally connected or directly connected), and the other end of the telescopic movable member is slidably matched with the movable cavity.

[0073] It can be understood that the pull rod 1212 pulls one end of the telescopic movable member to slide in the movable cavity, so that the other end of the telescopic movable member drives the first flexible transmission member 1227a and the second flexible transmission member 1227b to move synchronously, and then drives the first rotating body 1221 and the second rotating body 1221 to rotate synchronously, ensuring that the width adjustment is synchronized when the width of the frame device 100 is adjusted.

[0074] In combination with any of the above embodiments of the telescopic shaft assembly 111, Figure 5 as well as Figure 7 The wheel suspension 110 further includes a guide rail assembly 130 extending along the width direction X, and the first telescopic shaft 1111 and the second telescopic shaft 1112 are limitedly slidably matched with the guide rail assembly 130. In this way, the first telescopic shaft 1111 and the second telescopic shaft 1112 can be limitedly slidably matched with the guide rail assembly 130, which can improve the stability of the first telescopic shaft 1111 and the second telescopic shaft 1112 moving along the width direction X, thereby improving the width adjustment stability of the frame device 100.

[0075] Specifically, in one example, the guide rail assembly 130 is provided with a slot, and the first telescopic shaft 1111 and the second telescopic shaft 1112 are respectively inserted at both ends of the slot, so that the first telescopic shaft 1111 and the second telescopic shaft 1112 are limitedly slidably matched with the guide rail assembly 130. In another example, the first telescopic shaft 1111 and the second telescopic shaft 1112 are provided with a slider, and one of the slider and the slide rail assembly is provided with a convex portion, and the other is provided with a concave portion, and through the limited sliding cooperation of the convex portion and the concave portion, the first telescopic shaft 1111 and the second telescopic shaft 1112 can be limitedly slidably matched with the sliding assembly.

[0076] In some embodiments, the wheel assembly 113 is a universal wheel assembly. Specifically, the first roller and the second roller are universal wheels. In this way, by using the universal wheel assembly, the steering is flexible, which is convenient for the operator to operate the frame device 100 to perform a large angle steering in a small space, making the transportation equipment 10 run more smoothly.

[0077] Further, in combination with any of the above-mentioned embodiments of the first wheel assembly 1131 and the second wheel assembly 1132, in combination with FIG. 2 and Figure 4 As shown, the wheel suspension 110 further includes a third wheel assembly 1133. The third wheel assembly 1133 is disposed on a side of the second wheel assembly 1132 that is away from the first wheel assembly 1131, and is spaced apart from the second wheel assembly 1132. That is, the first wheel assembly 1131, the second wheel assembly 1132, and the third wheel assembly 1133 are sequentially spaced apart and arranged on the support frame 112. The first wheel assembly 1131 is disposed close to the first side 112a, and the second wheel assembly 1132 is disposed close to the second side 112b.

[0078] For ease of understanding, the following describes in detail the transportation scenarios of the transportation equipment 10 on flat roads and by the escalator equipment 20 .

[0079] Assuming that the transport equipment 10 is transported to a high place, it needs to pass through three transport sections, namely a low flat section, an escalator inclined section and a high flat section. Among them, the connection between the low flat section and the high flat section and the escalator inclined section can be a straight transition or a turning transition.

[0080] When the transport device 10 is transported to a flat road (such as driving to a low flat road section or a high flat road section), the operator can use the traction device 30 to pull the first side 112a of the support frame 112 to achieve the movement of the frame device 100. At this time, due to the large space for flat road transportation, the universal wheel setting of the first wheel assembly 1131 and the second wheel assembly 1132 is mainly used, and the rotation direction of the wheel assembly 113 is changed by the direction control assembly 160 (such as a steering wheel, etc.) to achieve flexible large-angle turning. At this time, the third wheel assembly 1133 is mainly affected by the movement trajectory of the first wheel assembly 1131 and the second wheel assembly 1132.

[0081] When the transport equipment 10 needs to be transferred from a horizontal flat road to an inclined escalator device 20 (such as from a low flat road section to an escalator inclined road section, or from an escalator inclined road section to a high flat road section), the following is a specific explanation using the low flat road section to the escalator inclined road section: through the mobility of the universal wheels in the first wheel assembly 1131 and the second wheel assembly 1132, smooth docking of the frame device 100 and the escalator device 20 is achieved. When the first wheel assembly 1131 and the second wheel assembly 1132 move onto the escalator device 20, they will be fixed to the escalator device 20, and the first wheel assembly 1131 and the second wheel assembly 1132 are stationary relative to the escalator device 20.

[0082] At this time, by setting the third wheel assembly 1133, and the third wheel assembly 1133 is a universal wheel assembly, the third wheel assembly 1133 can assist the frame device 100 in finally turning from the low flat road section to the escalator inclined section, ensuring that the frame device 100 can be completely turned and transported to the escalator device 20, and the frame device 100 can adapt to various angles of the escalator device 20, enriching the transportation scenarios of the frame device 100 and the escalator device 20.

[0083] In combination with any of the above embodiments of the frame device 100, Figures 8 to 9As shown, the frame device 100 also includes a traction force member 140 and a self-locking assembly 150. The traction force member 140 is used to be connected to the traction device 30 in a transmission manner, so that the traction device 30 pulls the traction force member 140 to drive the frame device 100 to move. In one example, the traction device 30 includes a traction rope and a driving motor. The traction rope is connected between the driving motor and the traction force member 140 in a transmission manner, so that the driving motor pulls the force member 140 through the traction rope. When the frame device 100 moves to the escalator device 20, the rotation speed of the driving motor can be controlled so that the movement rate of the traction rope is kept consistent with the transmission rate of the escalator device, which can minimize the power consumption of the driving motor. The self-locking assembly 150 is movably connected to the traction force member 121. The escalator device 20 is provided with a second locking portion 201. The self-locking assembly 150 is used to lock and cooperate with the second locking portion 201.

[0084] It is understandable that when the traction force member 121 is in transmission connection with the traction device 30, the traction force member 121 drives the self-locking assembly 150 to move in a direction away from the second locking portion 201, so that the self-locking assembly 150 is separated from the second locking portion 201, so that the frame device 100 can slide relatively on the escalator device 20. When the traction force member 121 is separated from the traction device 30, the self-locking assembly 150 resets in a direction close to the second locking portion 201, so that the self-locking assembly 150 is engaged and locked with the second locking portion 201, and the frame device 100 is locked to the escalator device 20.

[0085] In this way, through the locking cooperation between the self-locking component 150 and the second locking part 201, when the traction force-bearing member 140 is separated from the traction device 30 in transmission (such as the transmission separation caused by the driving motor of the traction device 30 stopping rotation, reversing, or the traction rope being disconnected), the frame device 100 can be locked by locking the self-locking component 150, thereby preventing the frame device 100 from sliding down and improving the safety of the material transportation process.

[0086] It should be noted that the self-locking component 150 can be but is not limited to electric drive, such as electromagnet drive engagement or electric screw active engagement, etc., and can also be mechanically locked, such as mechanical engagement locking, mechanical plug-in locking, etc., without too much restriction here.

[0087] In one embodiment, the self-locking assembly 150 includes an elastic reset member 153, a first hook member 151 and a second hook member 152. The traction force member 140 is elastically connected to the wheel suspension 110 through the elastic reset member 153, one end of the first hook member 151 is connected to the traction force member 140, and one end of the second hook member 152 is rotatably connected to the wheel suspension 110. The other end of the first hook member 151 overlaps with the other end of the second hook member 152. The escalator device 20 includes an escalator truss, and the escalator truss is provided with a second locking portion.

[0088] It is understandable that, combined with Figures 8 to 9 As shown, when the traction force receiving member 140 is in transmission connection with the traction device 30, the traction force receiving member 140 receives the traction force of the traction device 30 to compress the elastic reset member 153, so that the first hook member 151 is in the first position, the second hook member 152 is overlapped on the first hook member 151, and the second hook member 152 is separated from the second locking portion. That is, when the traction force receiving member 140 is in transmission connection with the traction device 30, the self-locking component 150 and the second locking portion are in an unlocked and separated state.

[0089] Combination Figure 10 to Figure 11 As shown, when the traction force-bearing member 140 is separated from the traction device 30 by transmission, the elastic reset member 153 is elastically reset, driving the traction force-bearing member 140 to rotate, so that one end of the first hook member 151 rotates in a direction away from the second hook member 152, so that the first hook member 151 and the second hook member 152 are separated, and the second hook member moves downward under the action of gravity, so that the second hook member 152 is locked and matched with the second locking portion, so that the frame device 100 is locked to the escalator device 20, to prevent the frame device 100 from falling on the escalator device 20.

[0090] In this way, the frame device 100 can be locked by the engagement and locking of the first hook member 151 and the second locking portion 201, thereby preventing the frame device 100 from sliding down and improving the safety of the material transportation process. Furthermore, the self-locking component 150 and the second locking portion adopt a mechanical locking method of engagement and locking, which has a simple structure and is convenient for processing and design, and is conducive to improving the processing efficiency of the transportation system 1.

[0091] In one example, see you later Figure 7 The frame device 100 further includes a first abutting protrusion 1113 and a second abutting protrusion 1114. The first abutting protrusion 1113 is arranged at one end of the first telescopic shaft 1111 away from the rotating body 1221, and the second abutting protrusion 1114 is arranged at one end of the second telescopic shaft 1112 away from the rotating body 1221. The frame device 100 abuts against the side wall of the escalator device 20 through the first abutting protrusion 1113 and the second abutting protrusion 1114. In this way, the side wall of the escalator device 20 can form a movement limit for the movement of the width adjustment assembly 120 through the setting of the abutting protrusion and the abutting cooperation with the side wall of the escalator device 20, so as to prevent the frame device 100 from being reset by the width adjustment assembly 120, and improve the structural strength of the frame device 100. Further, when the frame device 100 abuts against the side wall of the escalator device 20, the side wall of the escalator device 20 can increase a certain friction force, which is conducive to reducing the risk of the frame device 100 sliding down.
