[0001] The utility model relates to the technical field of engineering machinery, in particular to a fork-mounted device and a tool vehicle. Background Art

[0002] Large-scale mechanical equipment such as excavators, bulldozers, road rollers, loaders, power repair vehicles, and engineering rescue vehicles play an important role in mining, transportation, and crushing.

[0003] In the related art, large mechanical equipment needs to transfer large parts during maintenance. During the maintenance process, large parts are usually turned by forklifts. Since forklifts have a single function and can only transfer parts but cannot flip parts, large mechanical equipment needs to coordinate multiple cranes to flip large parts during maintenance.

[0004] However, since multiple different types of tool carts are required to cooperate with each other during equipment maintenance, the coordinated operation of multiple tool carts will inevitably increase the occupied area of ​​the maintenance site, the difficulty of personnel coordination and the difficulty of vehicle operation. Therefore, the maintenance of large mechanical equipment in related technologies is relatively difficult. Utility Model Content

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The technical solutions disclosed in various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 5 As shown, the embodiment of the utility model discloses a forklift device, which is applied to a tool vehicle. Specifically, the forklift device can be assembled on a vehicle body 200 of the tool vehicle. The vehicle body 200 here includes but is not limited to a frame body 210, a cab 220, a walking mechanism 230 and other functional devices. The disclosed forklift device includes at least two forklift assemblies 100.

[0022] Each fork-mounted assembly 100 includes a mounting bracket 110, a lifting mechanism 120, a telescopic mechanism 130, a rotating mechanism 140, and a fork-mounted plate 150. The mounting bracket 110 provides a mounting base for other components of the fork-mounted assembly 100. The mounting bracket 110 is connected to the vehicle body 200 of the tool vehicle, that is, each fork-mounted assembly 100 is fixedly mounted on the vehicle body 200 through its corresponding mounting bracket 110.

[0023] The lifting mechanism 120 is arranged on the mounting bracket 110, and the lifting mechanism 120 is connected to the telescopic mechanism 130, and the lifting mechanism 120 can drive the telescopic mechanism 130 to rise and fall. Specifically, the lifting mechanism 120 drives the telescopic mechanism 130 to rise and fall in the vertical direction. The telescopic mechanism 130 is connected to the fork-mounted plate 150 through the rotating mechanism 140. At this time, the telescopic mechanism 130 drives the rotating mechanism 140 and the fork-mounted plate 150 to move at the same time. The rotating mechanism 140 can drive the fork-mounted plate 150 to rotate. Here, the rotating mechanism 140 can drive an axis of the fork-mounted plate 150 to rotate. Optionally, the rotating mechanism 140 can drive the fork-mounted plate 150 to rotate around its central axis.

[0024] The fork-loading plates 150 of at least two fork-loading assemblies 100 are arranged relative to each other to form a clamping structure. The telescopic mechanism 130 can make the two fork-loading plates 150 relative to each other approach or move away from each other. At this time, when the two fork-loading plates 150 relative to each other approach each other, the object between the two fork-loading plates 150 will be clamped by the two relative fork-loading plates 150, so that the fork-loading device can perform a fork-loading operation on the object. It should be noted here that the fork-loading plates 150 relative to each other need to be operated synchronously, for example, synchronous lifting and synchronous rotation.

[0025] For the convenience of describing the present application, the present application takes two opposite fork-mounted assemblies 100 as an example, and the two opposite fork-mounted assemblies 100 may include a first fork-mounted assembly 101 and a second fork-mounted assembly 102. The components in the first fork-mounted assembly 101 may be recorded as a first mounting bracket, a first lifting mechanism, a first telescopic mechanism, a first rotating mechanism, and a first fork-mounted plate. The components in the second fork-mounted assembly may be recorded as a second mounting bracket, a second lifting mechanism, a second telescopic mechanism, a second rotating mechanism, and a second fork-mounted plate.

[0026] During the specific operation, when the object needs to be forked, the first telescopic mechanism drives the first fork loading plate to move in a direction close to the second fork loading plate. At the same time, the second telescopic mechanism drives the second fork loading plate to move in a direction close to the first fork loading plate. When both the first fork loading plate and the second fork loading plate are in contact with the object, the object is clamped by the first fork loading plate and the second fork loading plate. Then, the first lifting mechanism drives the first fork loading plate to rise by driving the first telescopic mechanism. At the same time, the second lifting mechanism drives the second lifting mechanism to rise by the second telescopic mechanism. Therefore, the fork loading device realizes the fork loading operation of the object.

[0027] When the object needs to be unloaded, the first lifting mechanism drives the first telescopic mechanism to lower the first fork loading tray. At the same time, the second lifting mechanism drives the second lifting mechanism to lower through the second telescopic mechanism. When lowered to the bearing base (ground) of the object, the first telescopic mechanism drives the first fork loading tray to move in a direction away from the second fork loading tray. The second telescopic mechanism drives the second fork loading tray to move in a direction away from the first fork loading tray. At this time, the first fork loading tray and the second fork loading tray are separated from the object, so the object is transferred to the bearing base to realize the unloading of the object.

[0028] When the forked object needs to be rotated, when the fork-loading device forks the forked object to a position that does not interfere with the supporting base, the rotating mechanism 140 corresponding to the fork-loading plate 150 drives the fork-loading plate 150 to rotate, thereby realizing the rotation of the object. For example, the first rotating mechanism drives the first fork-loading plate to rotate, and the second rotating mechanism drives the second fork-loading plate to rotate. When rotating the object, the object needs to be raised to a certain height to avoid the risk of interfering with the supporting base during the rotation process.

[0029] In the embodiments disclosed in the present application, the fork-loading disc 150 of each fork-loading assembly 100 and the fork-loading disc 150 of another fork-loading assembly 100 arranged opposite thereto can form a clamping structure. Therefore, the two opposite fork-loading discs 150 can form a clamping structure to clamp an object. In addition, the rotating mechanism 140 can drive the corresponding rotating disc to rotate, so that the flipping operation of the object can be realized. Therefore, the fork-loading device disclosed in the present application can not only realize the fork loading of the object but also realize the flipping operation of the object. Therefore, the tool cart equipped with the fork-loading device of the present application can not only realize the transportation of the object but also realize the flipping of the object. Therefore, it can meet the different operations in the maintenance process of large-scale mechanical equipment, so there is no need for multiple tool carts of different types to cooperate with each other, thereby reducing the occupied area of ​​the maintenance site, reducing the coordination difficulty of personnel and the operation difficulty of the vehicle. Therefore, the fork-loading device disclosed in the present application can reduce the maintenance difficulty of large-scale mechanical equipment.

[0030] In addition, the fork-mounted device disclosed in the present application can perform fork-mounted and flipping operations on equipment parts, thereby improving the maintenance efficiency of large-scale mechanical equipment, reducing manual labor participation, and improving maintenance safety and convenience.

[0031] Optionally, the lifting mechanism 120 generally drives the fork loading plate 150 to rise and fall in the vertical direction, while the telescopic mechanism 130 drives the fork loading plate 150 to move in a direction perpendicular to the direction in which the fork loading plate 150 is lifted and lowered. In other words, the lifting mechanism 120 drives the fork loading plate 150 to rise and fall in the height direction of the vehicle body 200, and the telescopic mechanism 130 drives the fork loading plate 150 to move in the width direction or the length direction of the vehicle body 200.

[0032] In order to improve the fork mounting reliability of the fork mounting device, in another optional embodiment, the surface of the fork mounting plate 150 on the side away from the rotating mechanism 140 can be provided with a plurality of abutment protrusions 151, and the plurality of abutment protrusions 151 are arranged at intervals. The surface of the fork mounting plate 150 on the side away from the rotating mechanism 140 mentioned here refers to the surface on the opposite side of the two fork mounting plates 150. In this scheme, the fork mounting plate 150 is provided with abutment protrusions 151, and the abutment protrusions 151 can abut or plug with part of the object, thereby increasing the friction between the fork mounting plate 150 and the object, thereby improving the clamping strength of the fork mounting plate 150 on the object, and thus improving the reliability of the fork mounting of the fork mounting device.

[0033] Optionally, the number of the abutment protrusions 151 may be two, three or more, and the specific number of the abutment protrusions 151 may be flexibly selected according to actual working conditions.

[0034] In another optional embodiment, the fork mounting assembly 100 may further include a first guide portion 161 and a second guide portion 162, and the first guide portion 161 may be fixedly connected to the mounting bracket 110. The second guide portion 162 may be fixedly connected to the telescopic mechanism 130, that is, the second guide portion 162 may be fixedly mounted on the telescopic mechanism 130. The first guide portion 161 and the second guide portion 162 may be slidably matched along the moving direction of the telescopic mechanism 130.

[0035] In this solution, the first guide portion 161 and the second guide portion 162 can assist in guiding the lifting direction of the telescopic mechanism 130, thereby improving the lifting accuracy of the telescopic mechanism 130. In addition, the first guide portion 161 and the second guide portion 162 can assist in supporting the telescopic mechanism 130, thereby improving the assembly reliability of the fork-mounted device.

[0036] Optionally, the first guide portion 161 may be a guide rail, and the second guide portion 162 may be a slider, and the slider may be fixed on the housing of the telescopic mechanism 130 , and in this case, the slider is slidably matched with the guide rail.

[0037] In another optional embodiment, if Figure 2 As shown, the first guide portion 161 includes a first guide rail 1611 and a second guide rail 1612, and the first guide rail 1611 and the second guide rail 1612 are both fixedly connected to the mounting bracket 110. The second guide portion 162 includes a first guide sleeve 1621 and a second guide sleeve 1622, and the first guide sleeve 1621 and the second guide sleeve 1622 can be respectively located on opposite sides of the telescopic mechanism 130. The first guide sleeve 1621 can be mounted on the first guide rail 1611. The second guide sleeve 1622 can be mounted on the second guide rail 1612.

[0038] In this solution, the guide sleeve can be mounted on the track, so the connection reliability between the guide sleeve and the track can be improved, thereby further improving the guiding performance and auxiliary support performance of the telescopic mechanism 130. In addition, the double-track guiding method can also further improve the auxiliary support performance of the telescopic mechanism 130. Therefore, this solution can not only further improve the guiding performance of the telescopic mechanism 130, but also further improve the auxiliary support performance of the telescopic mechanism 130. Therefore, this solution can further improve the assembly reliability of the fork-mounted device.

[0039] In another optional embodiment, the lifting mechanism 120 may include a main body 121 and a drive shaft 122, and the main body 121 may be mounted outside the drive shaft 122. The drive shaft 122 may move relative to the main body 121. The end of the drive shaft 122 away from the main body 121 may be connected to the telescopic mechanism 130. The drive shaft 122 may drive the telescopic mechanism 130 to rise and fall. The drive shaft 122 here is the power end of the lifting mechanism 120, and the main body 121 is the fixed end of the lifting mechanism 120. The telescopic mechanism 130 is connected to the drive shaft 122. The main body 121 here includes components such as a housing and a power generating member. The main body 121 can generate a force to drive the drive shaft 122 to move. At this time, the lifting mechanism 120 may be a power structure such as a linear motor, a hydraulic cylinder or a pneumatic cylinder. In this solution, the structure of the lifting mechanism 120 is simple, so the manufacturing cost of the fork-mounted device can be reduced.

[0040] Of course, the lifting mechanism 120 may also be other structures, for example, the lifting mechanism 120 may include a combined mechanical structure of a motor, a worm gear, etc. The specific structure of the lifting mechanism 120 is not limited herein.

[0041] The telescopic mechanism 130 in the above embodiment may also be a power structure such as a hydraulic cylinder or a pneumatic cylinder.

[0042] In another optional embodiment, the telescopic mechanism 130 may include a fixed sleeve 131, a movable sleeve 132 and a driving source 133, wherein the fixed sleeve 131 and the movable sleeve 132 are fitted together, and the fixed sleeve 131 and the movable sleeve 132 may form a receiving space. The fixed sleeve 131 here may be fitted outside the movable sleeve 132, or the movable sleeve 132 may be fixed outside the fixed sleeve 131. The driving source 133 may be arranged in the receiving space, and the fixed end of the driving source 133 may be connected to the fixed sleeve 131. The fixed end of the driving source 133 here may specifically be a housing of the driving source 133. The moving end of the driving source 133 may be connected to the movable sleeve 132. The moving end of the driving source 133 here may specifically be a moving shaft of the driving source 133. The driving source 133 may drive the fixed sleeve 131 and the movable sleeve 132 to move relative to each other. The fixed sleeve 131 is connected to the lifting mechanism 120 , and one end of the movable sleeve 132 away from the fixed sleeve 131 is connected to the rotating mechanism 140 .

[0043] In a specific operation process, when the lifting mechanism 120 drives the fixed sleeve 131, the telescopic mechanism 130 can be lifted and lowered. The driving source 133 drives the movable sleeve 132 to move relative to the fixed sleeve 131, thereby moving the fork loading plate 150.

[0044] In this solution, the fixed sleeve 131 and the movable sleeve 132 are fitted together to form a receiving space, and the driving source 133 is located in the receiving space, so that the driving source 133 is not exposed. Therefore, during the operation of the fork-mounted device, objects are not easy to collide or interfere with the driving source 133, thereby improving the safety of the driving source 133, and further improving the safety performance of the fork-mounted device. In addition, the part where the fixed sleeve 131 and the movable sleeve 132 are fitted together can also improve the assembly strength of the telescopic mechanism 130, thereby further improving the safety and reliability of the telescopic mechanism 130.

[0045] Optionally, the driving source 133 may be a driving motor, a hydraulic cylinder, a pneumatic cylinder or other power structures. Of course, the driving source 133 may also be other structures which are not limited herein.

[0046] In the above embodiment, the rotating mechanism 140 can be a rotating motor, the motor shaft of the rotating motor can be directly connected to the fork plate 150, and the housing of the rotating motor can be fixedly connected to the telescopic mechanism 130. Specifically, the housing of the rotating motor can be fixedly connected to the movable sleeve 132 mentioned above.

[0047] In an optional solution, the rotating mechanism 140 may include a power source 141, a fixed disk 142 and a transmission member 143, and the fork-mounted disk 150 may be overlapped with the fixed disk 142 and rotatably connected. The fork-mounted disk 150 is in transmission connection with the transmission member 143. The fixed disk 142 is used to provide a mounting base for other components of the rotating mechanism 140. The fixed disk 142 may be connected to the telescopic mechanism 130. The fixed disk 142 is used to achieve a fixed connection between the rotating mechanism 140 and the telescopic mechanism 130. Optionally, the fixed disk 142 may be fixed on the above-mentioned movable sleeve 132.

[0048] The power source 141 and the transmission member 143 may be disposed on the fixed plate 142, and the power source 141 provides a rotational force for the fork-mounted plate 150. The power source 141 may drive the fork-mounted plate 150 to rotate through the transmission member 143.

[0049] In this solution, the fixing plate 142 can provide a certain supporting force for the fork-loading plate 150 , thereby further improving the installation reliability of the fork-loading plate 150 .

[0050] In addition, by providing different types of transmission members 143 , different transmission ratios can be obtained, thereby further improving the transmission reliability of the rotating mechanism 140 .

[0051] Optionally, the power source 141 may be a DC motor, a synchronous motor, an asynchronous motor, or a servo motor or other power structures. Of course, the power source 141 may also be other power structures, which is not limited herein.

[0052] In one embodiment, the transmission member 143 can be a worm gear structure, the power source 141 can be connected to the worm, the worm wheel is connected to the fork-mounted plate 150, and the worm wheel and the worm gear are in driving cooperation. At this time, the power source 141 can drive the fork-mounted plate 150 to rotate through the worm gear structure.

[0053] Alternatively, in another solution, the transmission member 143 may be a planetary gear structure, and the power source 141 may drive the fork plate 150 to rotate through the planetary gear structure. Of course, the specific structure of the transmission member 143 is not limited to the two structures disclosed herein, and the transmission member 143 may also be other structures, which are not limited herein.

[0054] Based on the fork-mounted device disclosed in the embodiment of the present application, the embodiment of the present application further discloses a tool vehicle, and the disclosed tool vehicle includes the fork-mounted device described in any of the above embodiments.

[0055] The tool vehicle disclosed in the present application also includes a vehicle body 200, and the vehicle body 200 includes a frame body 210, a cab 220 and a traveling mechanism 230, and the traveling mechanism 230, the cab 220 and the fork-mounted device are all arranged on the frame body 210. Specifically, each fork-mounted assembly 100 is fixedly connected to the frame body 210 through its corresponding mounting bracket 110. The frame body 210 here is the installation base of the tool vehicle. The traveling mechanism 230 integrates the walking and steering functions. The cab 220 is used to drive and control the tool vehicle. For example, a control system is integrated in the cab 220, and the control system may include control devices such as a main control platform, an operating platform, and control buttons, and the control system can realize the control of the fork-mounted device and the traveling mechanism 230. The control system is a well-known technology in the art and will not be elaborated herein.

[0056] Taking the maintenance of a dump truck as an example, the operator controls the tool cart in the cab 220 and moves the tool cart to the location of the dump truck through the walking mechanism 230. At this time, the dump truck is located between the first fork-mounted assembly 101 and the second fork-mounted assembly 102, and the first fork-mounted assembly 101 and the second fork-mounted assembly 102 cooperate to fork-mount the dump truck's box bucket. Then the dump truck's box bucket is separated from the mining truck chassis. Then the box bucket is transported to the maintenance area. Of course, when the box bucket needs to be flipped, the first fork-mounted assembly 101 and the second fork-mounted assembly 102 can also be used to flip the box bucket.

[0057] In the above embodiment, the walking mechanism 230 may include a driving wheel, a motor and a suspension assembly, and the suspension assembly may include a rotating arm, a fixed base and a shock-absorbing elastic member, wherein the first end of the rotating arm is rotatably connected to the fixed base; and the second end of the rotating arm is elastically connected to the fixed base through the shock-absorbing elastic member. The fixed base here is used to fix and install the suspension assembly, and the fixed base provides a direct or indirect installation position for other components of the walking mechanism 230. The walking mechanism 230 is fixedly installed on the frame body 210 through the fixed base. The elastic force generated by the compression or extension of the shock-absorbing elastic member will be transmitted to the rotating arm, and the rotating arm will rotate around its first end to adapt to the expansion and contraction of the shock-absorbing elastic member.

[0058] At this time, the traveling mechanism 230 is fixedly assembled on the vehicle frame body 210 through a fixed base. When the tool vehicle is traveling, the motor is started, and the motor drives the driving wheel to rotate. The friction between the driving wheel and the ground causes the driving wheel to drive the vehicle body 200 and the frame body 210 forward, so that the tool vehicle can travel normally. When the tool vehicle travels to a raised road surface, the driving wheel swings upward along with the rotating arm, and the second end of the rotating arm compresses the shock-absorbing elastic member to adapt to the raised road surface; when the tool vehicle travels to a sunken road surface, the driving wheel swings downward along with the rotating arm, and the shock-absorbing elastic member extends to adapt to the sunken road surface.

[0059] In this solution, the elastic force generated by the compression or extension of the shock-absorbing elastic member is transmitted to the driving wheel through the rotating arm, so that the driving wheel swings up and down with the rotating arm to adapt to the uneven ground, thereby avoiding the driving wheel from being suspended in the air, thereby improving the grip of the tool cart, thereby avoiding the risk of the tool cart slipping, and thus improving the reliability of the tool cart. At the same time, because the driving wheel swings up and down with the rotating arm, it can adapt to the ruggedness of the road surface, thereby making the tool cart run more smoothly and improving the driving stability of the tool cart.

[0060] Alternatively, in another optional embodiment, the walking mechanism 230 may also be a crawler structure, which can adapt to more road conditions. The specific structure of the crawler structure is a well-known technology and will not be described in detail herein.

[0061] In addition, the running mechanism 230 may also have an independent height adjustment function to achieve a leveling effect on the frame body 210. Of course, the running mechanism 230 may also be other structures, and this article only discloses a feasible solution and is not used to limit the specific structure of the running mechanism 230.

[0062] In the above embodiment, the number of the running mechanisms 230 may be multiple, for example, there may be four running mechanisms, which are respectively located at four diagonal corners of the frame body 210. Of course, the number of the running mechanisms may also be other, which is not limited herein.

[0063] In another optional embodiment, the frame body 210 may include a fixed bracket 211, a movable bracket 212, a guide rail portion 213 and a driving portion 214. The cab 220 may be arranged on the fixed bracket 211 or the movable bracket 212, and the fixed bracket 211 and the movable bracket 212 are arranged at intervals along the extension direction of the guide rail portion 213. The fixed bracket 211 may be fixedly connected to the guide rail portion 213, and the movable bracket 212 may be slidably connected to the guide rail portion 213 along the extension direction of the guide rail portion 213. The guide rail portion 213 here is used to realize the connection between the fixed bracket 211 and the movable bracket 212, and to realize the guiding function of the movable bracket 212.

[0064] The driving part 214 can be disposed on the fixed bracket 211 or the guide rail part 213, and the driving part 214 is connected to the movable bracket 212, and the driving part 214 is used to drive the movable bracket 212 to move along the extension direction of the guide rail part 213. The first fork mounting assembly 101 mentioned above can be disposed on the fixed bracket 211, and the second fork mounting assembly 102 can be disposed on the movable bracket 212.

[0065] In this solution, the distance between the movable bracket 212 and the fixed bracket 211 can be adjusted by the driving unit 214, thereby realizing the variable span function of the frame body 210, thereby enabling the frame body 210 to adapt to equipment to be repaired of different sizes, thereby improving the compatibility of the tool cart.

[0066] Optionally, the driving part 214 may be a power structure such as a hydraulic cylinder, a pneumatic cylinder, etc. Of course, the driving part 214 may also be other structures which are not limited herein.

[0067] The guide rail portion 213 in the above embodiment may be a single guide rail structure. In this case, since the span between the fixed bracket 211 and the movable bracket 212 is large, its stability and safety are poor.

[0068] Based on this, in another optional embodiment, the guide rail portion 213 may include a first guide rail 2131 and a second guide rail 2132, and both ends of the fixed bracket 211 may be fixedly connected to the first guide rail 2131 and the second guide rail 2132 respectively. Both ends of the movable bracket 212 may be slidably connected to the first guide rail 2131 and the second guide rail 2132 respectively. The first guide rail 2131 and the second guide rail 2132 may be parallel. The fork mounting device may be located between the first guide rail 2131 and the second guide rail 2132.

[0069] In this solution, the fixed bracket 211 and the movable bracket 212 are slidably connected by the first guide rail 2131 and the second guide rail 2132, so the frame body 210 is a gantry double support structure, which can achieve large-span lateral support, thereby improving the stability and safety of the frame body 210.

[0070] Furthermore, the number of the driving parts 214 may be at least two, namely a first driving part and a second driving part. The first driving part and the second driving part are respectively located at two ends of the moving bracket 212 and connected to the two ends of the moving bracket 212 .

[0071] In this solution, the frame body 210 is a dual-drive structure, so that a large-span lateral drive can be achieved, thereby further improving the safety and reliability of the frame body 210 and avoiding the risk of tilting on both sides of the mobile bracket 212.

[0072] In another optional embodiment, the mobile bracket 212 is further provided with a rolling assembly, the rolling assembly includes a support frame 215 and a sliding roller, and the sliding roller is rotatably arranged on the support frame 215. The mobile bracket 212 is fixedly connected to the support frame 215. It can be understood here that the support frame 215 is a partial structure of the mobile bracket 212. The sliding roller can be rollingly connected to the guide rail portion 213. At this time, the mobile bracket 212 is slidingly connected to the guide rail portion 213 through the sliding roller.

[0073] In a specific operation process, when the driving part 214 drives the fixed bracket 211 and the movable bracket 212 to move relative to each other, the friction force between the sliding roller and the guide rail part 213 can drive the sliding roller to roll.

[0074] In this solution, the sliding roller and the guide rail portion 213 are in rolling cooperation, so the friction between the movable bracket 212 and the guide rail portion 213 can be reduced, thereby making the span changing operation of the movable bracket 212 smoother and less prone to the risk of jamming or blocking.

[0075] In the above embodiment, in order to avoid the risk of the mobile bracket 212 being deflected during the movement, a guide groove can be opened on the guide rail portion 213, and part of the sliding roller can be embedded in the guide groove, thereby avoiding the risk of the sliding roller tilting and rolling, thereby avoiding the risk of the mobile bracket 212 being deflected during the movement.

[0076] In another optional embodiment, the rolling assembly may further include a first limiting member 216a and a second limiting member 216b, and the arrangement direction of the first limiting member 216a and the second limiting member 216b is perpendicular to the extension direction of the guide rail portion 213. The first limiting member 216a and the second limiting member 216b may each include a limiting roller 2161 and a rotating shaft 2162, the rotating shaft 2162 is fixed to the support frame 215, and the limiting roller 2161 is rotatably connected to the rotating shaft 2162. The guide rail portion 213 is located between the limiting roller 2161 of the first limiting member 216a and the limiting roller 2161 of the second limiting member 216b, and the guide rail portion 213 and the limiting rollers 2161 on both sides can roll together.

[0077] In this solution, the limiting roller 2161 of the first limiting member 216a and the limiting roller 2161 of the second limiting member 216b can limit the movable bracket 212 along the width direction of the guide rail portion 213, thereby avoiding the risk of the movable bracket 212 being deflected.

[0078] In a specific solution, when the guide rail portion 213 includes the first guide rail 2131 and the second guide rail 2132 , the first and second limit members 216 a and 216 b mentioned above may be provided on both sides of the first and second guide rails 2131 and 2132 .

[0079] The above embodiments of the present invention focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0080] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
