Description

Technical Field

[0001] This invention relates to the field of photovoltaic equipment technology, and in particular to a photovoltaic panel module cleaning device. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at semiconductor interfaces. It is a clean energy source with a very promising future. Photovoltaic panels are typically installed in sunny outdoor environments. Over time, dust, bird droppings, leaves, and other debris easily accumulate on the surface of the panels. This dirt reduces the solar-facing area and light absorption efficiency, severely impacting the power generation efficiency (data shows that not cleaning photovoltaic panels for a year can reduce efficiency by more than 20%). To improve both power generation and cleaning efficiency, automated cleaning devices are typically installed on the photovoltaic panels to clean them.

[0003] A typical photovoltaic (PV) panel cleaning device includes a traveling beam, a scraper assembly mounted on the traveling beam, and a drive assembly connected to the traveling beam. The movement of the drive assembly drives the traveling beam and the scraper assembly to reciprocate, thus cleaning the PV panel (similar to the principle of a car windshield wiper). Existing PV panel cleaning devices generally use drive wheels (such as rubber wheels) as the traveling component of the drive assembly. That is, the drive wheels are in direct contact with the surface of the PV panel, and a motor drives the drive wheels to move across the PV panel.

[0004] However, in some extreme weather conditions (such as rain and snow), the drive wheels are prone to slipping on the photovoltaic panels, affecting the movement of the photovoltaic panel cleaning device. In severe cases, the device may become completely immobile, rendering it unable to function properly. Furthermore, photovoltaic arrays are typically assembled from multiple photovoltaic panels. Due to assembly errors, unevenness, misalignment of upper and lower surfaces, and / or gaps may exist between adjacent panels. This necessitates the cleaning device traversing obstacles when moving from one panel to another. The drive wheels have relatively poor obstacle-crossing capabilities, easily colliding with the edges of the panels or failing to cross obstacles altogether, thus affecting the normal operation of the cleaning device. Summary of the Invention

[0005] The purpose of this invention is to provide a photovoltaic panel cleaning device that uses a track or timing belt as the walking component of the photovoltaic panel cleaning device, thereby greatly improving the walking and passing capability of the photovoltaic panel cleaning device.

[0006] This invention provides a photovoltaic panel module cleaning device, including a cleaning system and a drive assembly. The cleaning system includes a traveling beam and a scraper assembly disposed on the traveling beam. The drive assembly is disposed corresponding to the end of the traveling beam. The drive assembly includes a mounting plate, a drive device, and a sprocket assembly. The mounting plate is located on one side of the traveling beam, and the sprocket assembly is located between the mounting plate and the traveling beam. The mounting plate is connected to the end of the traveling beam. The sprocket assembly includes a transmission belt, a driving sprocket, and a driven sprocket. The transmission belt surrounds the driving sprocket and the driven sprocket, and the driving sprocket and the driven sprocket are driven by the transmission belt. The transmission belt is a track belt or a synchronous belt, and the transmission belt is used to contact the photovoltaic panel module. The drive device is fixed on the mounting plate, and the drive device is connected to the driving sprocket and used to drive the driving sprocket to rotate. The driven sprocket is rotatably connected to the mounting plate.

[0007] In one possible implementation, the drive assembly further includes a pressure roller assembly located below and vertically opposite to the sprocket assembly; the pressure roller assembly includes a pressure roller rotatably connected to the mounting plate, the pressure roller being used to contact the photovoltaic panel assembly; the pressure roller assembly is used to cooperate with the sprocket assembly to press the photovoltaic panel assembly firmly from its upper and lower sides respectively.

[0008] In one possible implementation, the drive assembly further includes an elastic floating support assembly, through which the pressure roller is connected to the mounting plate. The elastic floating support assembly is capable of vertical extension and retraction relative to the mounting plate, thereby enabling the pressure roller to move vertically relative to the mounting plate.

[0009] In one possible embodiment, the elastic floating support assembly includes an elastic element, a connecting bracket, and a pressure roller support frame. The pressure roller support frame includes a support portion and a connecting rod portion. The support portion has a U-shaped structure, and the pressure roller is located inside the support portion. A rotating shaft is provided at the center of the pressure roller, and the two opposite ends of the rotating shaft are respectively connected to the two opposite side walls of the support portion. The connecting bracket is fixedly connected to the mounting plate and has a through hole. The top end of the connecting rod portion is fixedly connected to the support portion, and the bottom end of the connecting rod portion is inserted into the through hole and can move up and down within the through hole. The elastic element is sleeved on the connecting rod portion, and the two ends of the elastic element abut against the support portion and the connecting bracket, respectively.

[0010] In one possible implementation, the elastic floating support assembly further includes a guide bracket, which is fixedly connected to the mounting plate. The guide bracket has a U-shaped structure, and both the pressure roller and the support portion are located within the guide bracket. Guide grooves are provided on the inner walls of opposite sides of the guide bracket, and the guide grooves extend vertically. The opposite ends of the rotating shaft pass through the opposite two side walls of the support portion and are inserted into the guide grooves on opposite sides of the guide bracket. The rotating shaft can move up and down within the guide grooves.

[0011] In one possible implementation, there are multiple pressure rollers arranged sequentially along the moving direction of the drive assembly. The multiple pressure rollers include two large pressure rollers and at least one small pressure roller, with at least one small pressure roller located between the two large pressure rollers. The two large pressure rollers have the same outer diameter, and the outer diameter of the small pressure roller is smaller than that of the large pressure rollers.

[0012] In one possible implementation, the drive assembly further includes a roller assembly located on one side of the sprocket assembly and between the sprocket assembly and the pressure roller assembly; the roller assembly includes a roller rotatably connected to the mounting plate and used to contact the sidewall of the photovoltaic panel assembly.

[0013] In one possible implementation, the number of the pulleys is multiple, and the multiple pulleys are arranged sequentially along the moving direction of the drive assembly. The multiple pulleys include two large pulleys and at least one small pulley, and at least one small pulley is located between the two large pulleys. The two large pulleys have the same outer diameter, and the outer diameter of the small pulley is smaller than the outer diameter of the large pulleys.

[0014] In one possible implementation, the end of the traveling beam is provided with a connecting rod, one end of which is connected to the traveling beam, and the other end of which passes through the sprocket assembly and is connected to the mounting plate.

[0015] In one possible implementation, the driving sprocket and the driven sprocket are spaced apart within the drive belt, and the connecting rod passes through the gap between the driving sprocket and the driven sprocket within the drive belt and connects to the mounting plate.

[0016] The photovoltaic panel cleaning device provided by the present invention utilizes a sprocket assembly as the walking component of the drive assembly. The transmission belt of the sprocket assembly is a track or a synchronous belt. That is, the track or synchronous belt is used as the walking component of the photovoltaic panel cleaning device. The track and synchronous belt have good anti-slip performance and obstacle crossing performance, thereby enabling the photovoltaic panel cleaning device to have good walking and passing ability and to walk and work normally even in extreme environments.

[0031] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0032] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification and claims of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0033] The directional terms such as "up," "down," "left," "right," "front," "back," "top," and "bottom" (if present) used in the specification and claims of this invention are defined by the position of the structures in the drawings and the relative positions of the structures, and are only for the clarity and convenience of expressing the technical solution. It should be understood that the use of directional terms should not limit the scope of protection claimed by this invention.

[0034] like Figure 1 , Figure 2 and Figure 5 As shown, the photovoltaic panel cleaning device provided in this embodiment of the invention is used to install on a photovoltaic panel 4 to clean the photovoltaic panel 4. The photovoltaic panel cleaning device includes a cleaning system 1 and a drive component 3. The cleaning system 1 includes a traveling beam 11 and a scraper assembly 13 disposed on the traveling beam 11. The drive component 3 is disposed at the end of the traveling beam 11 and connected to the end of the traveling beam 11. The drive component 3 can move on the photovoltaic panel 4. Through the movement of the drive component 3, the traveling beam 11 and the scraper assembly 13 are moved on the photovoltaic panel 4, thereby cleaning the photovoltaic panel of the photovoltaic panel 4 (similar to the principle of a car windshield wiper).

[0035] like Figure 3 , Figure 4 and Figure 7 As shown, in one embodiment, the drive assembly 3 includes a mounting plate 31, a drive device 32, and a sprocket assembly 33. The mounting plate 31 is located on one side of the sprocket assembly 33. The sprocket assembly 33 includes a drive belt 331, a drive sprocket 332, and a driven sprocket 333. The drive belt 331 surrounds the drive sprocket 332 and the driven sprocket 333, and the drive sprocket 332 and the driven sprocket 333 are driven by the drive belt 331. The drive belt 331 is a track or a synchronous belt, and it is used to contact the photovoltaic panel assembly 4 and travel on the surface of the photovoltaic panel assembly 4. The drive device 32 is fixed on the mounting plate 31 and is connected to the drive sprocket 332 to drive the drive sprocket 332 to rotate. The driven sprocket 333 is rotatably connected to the mounting plate 31. During operation, the drive device 32 drives the drive sprocket 332 to rotate, and the rotation of the drive sprocket 332 drives the drive belt 331 and the driven sprocket 333 to rotate, thereby driving the entire drive assembly 3 to move.

[0036] Specifically, the photovoltaic panel cleaning device provided in this embodiment uses a sprocket assembly 33 as the walking component of the drive assembly 3. The transmission belt 331 of the sprocket assembly 33 is a track or a timing belt. That is, the track or timing belt is used as the walking component of the photovoltaic panel cleaning device. The track and timing belt have good anti-slip performance and obstacle crossing performance, so that the photovoltaic panel cleaning device has good walking and passing ability and can walk and work normally even in extreme environments.

[0037] like Figure 7 As shown, in one embodiment, the transmission belt 331 is a track.

[0038] like Figure 7 and Figure 8 As shown, in one embodiment, the drive assembly 3 further includes a pressure roller assembly 34, which is located below and vertically opposite to the sprocket assembly 33. The sprocket assembly 33 is located above the photovoltaic panel assembly 4, and the pressure roller assembly 34 is located below the photovoltaic panel assembly 4. The pressure roller assembly 34 includes a pressure roller 340, which is vertically arranged and rotatably connected to the mounting plate 31. The pressure roller 340 is used to contact the photovoltaic panel assembly 4. The pressure roller assembly 34 cooperates with the sprocket assembly 33 to press the photovoltaic panel assembly 4 from both the upper and lower sides, thereby increasing the friction of the sprocket assembly 33 during movement and preventing slippage.

[0039] like Figure 7 and Figure 8 As shown, in one embodiment, the drive assembly 3 also includes an elastic floating support assembly 35. The pressure roller 340 is connected to the mounting plate 31 through the elastic floating support assembly 35. The elastic floating support assembly 35 can extend and retract relative to the mounting plate 31, thereby enabling the pressure roller 340 to move up and down relative to the mounting plate 31.

[0040] Specifically, due to manufacturing tolerances and assembly errors of the photovoltaic panel assembly 4, unevenness may occur on the surface of the photovoltaic panel assembly 4 and between adjacent photovoltaic panel assemblies 4. In this embodiment, an elastic floating support assembly 35 is provided. The elastic floating support assembly 35 can provide tension to the pressure roller 340, so that the pressure roller 340 can always be in close contact with the surface of the photovoltaic panel assembly 4. This ensures that the sprocket assembly 33 and the pressure roller assembly 34 maintain a large friction with the photovoltaic panel assembly 4. At the same time, when the drive assembly 3 passes over the uneven surface (such as steps) of the photovoltaic panel assembly 4, the pressure roller assembly 34 can float up and down, so that the drive assembly 3 can smoothly cross obstacles, thereby further improving the walking and passing ability of the photovoltaic panel assembly cleaning device.

[0041] like Figure 7 , Figure 8 , Figure 11 and Figure 12 As shown, in one embodiment, the elastic floating support assembly 35 includes an elastic element 351, a connecting bracket 352, and a pressure roller support frame 353. The pressure roller support frame 353 has a Y-shaped structure and includes a support portion 3531 and a connecting rod portion 3532. The support portion 3531 has a U-shaped structure, and the pressure roller 340 is located inside the support portion 3531. A rotating shaft 343 is provided at the center of the pressure roller 340, and the two opposite ends of the rotating shaft 343 are respectively connected to the two opposite side walls of the support portion 3531. The connecting bracket 352 is fixedly connected to the mounting plate 31. The connecting bracket 352 has a through hole 3521. The top end of the connecting rod portion 3532 is fixedly connected to the support portion 3531, and the bottom end of the connecting rod portion 3532 is inserted into the through hole 3521 and can move up and down within the through hole 3521. The elastic element 351 is sleeved on the connecting rod portion 3532, and the two ends of the elastic element 351 abut against the support portion 3531 and the connecting bracket 352 respectively.

[0042] Specifically, in this embodiment, the connecting bracket 352 has an L-shaped structure, the top end of the connecting bracket 352 is fixedly connected to the mounting plate 31, and the through hole 3521 is provided at the bottom end of the connecting bracket 352. The elastic element 351 is a spring.

[0043] like Figure 7 , Figure 8 , Figure 11 and Figure 12 As shown, in one embodiment, the elastic floating support assembly 35 further includes a guide bracket 354, which is fixedly connected to the mounting plate 31. The guide bracket 354 has a U-shaped structure, and the pressure roller 340 and the support portion 3531 are both located inside the guide bracket 354. Guide grooves 3541 are provided on the inner walls of opposite sides of the guide bracket 354. The guide grooves 3541 extend vertically. The opposite ends of the rotating shaft 343 pass through the opposite two side walls of the support portion 3531 and are inserted into the guide grooves 3541 on opposite sides of the guide bracket 354. The rotating shaft 343 can move up and down within the guide grooves 3541.

[0044] Specifically, in this embodiment, when the pressure roller 340 is subjected to downward pressure, the pressure roller 340, together with the rotating shaft 343 on the pressure roller 340, moves downward along the guide groove 3541 on the guide bracket 354, and at the same time drives the entire pressure roller support frame 353 to move downward. At this time, the elastic element 351 further compresses and stores force. When the pressure roller 340 is no longer subjected to downward pressure, the pressure roller 340 and the pressure roller support frame 353 move upward under the elastic force of the elastic element 351, thereby realizing the up and down elastic floating of the pressure roller 340 and ensuring that the pressure roller 340 can always be in close contact with the surface of the photovoltaic panel module 4.

[0045] like Figure 7 and Figure 11As shown, in one embodiment, there are multiple pressure rollers 340, which are arranged sequentially along the moving direction of the drive assembly 3, and the tops of the multiple pressure rollers 340 are kept flush (on the same plane). The multiple pressure rollers 340 include two large pressure rollers 341 and at least one small pressure roller 342, with the at least one small pressure roller 342 located between the two large pressure rollers 341; the two large pressure rollers 341 have the same outer diameter, and the outer diameter of the small pressure roller 342 is smaller than that of the large pressure rollers 341.

[0046] Specifically, in this embodiment, there is one small pressure roller 342 (of course, in other embodiments, the number of small pressure rollers 342 can be set to more according to actual needs). This small pressure roller 342 is located between the two large pressure rollers 341, that is, the two large pressure rollers 341 are located on the outermost side of the pressure roller assembly 34. The two large pressure rollers 341 are respectively connected to the mounting plate 31 through the elastic floating support assembly 35. The small pressure roller 342 located in the middle is connected to the large pressure rollers 341 on both sides through the clamping plate 344 (that is, the small pressure roller 342 is not connected to the mounting plate 31 through the elastic floating support assembly 35, thereby saving component cost and space).

[0047] In this embodiment, multiple pressure rollers 340 are arranged so that when the pressure roller assembly 34 crosses obstacles such as gaps or steps between photovoltaic panel components 4, the foremost pressure roller 340 contacts the obstacle first and its position shifts, while the other pressure rollers 340 remain in contact with the surface of the photovoltaic panel component 4 (at least two pressure rollers 340 remain in contact with the surface of the photovoltaic panel component 4). This ensures that the overall posture of the pressure roller assembly 34 does not change or only changes slightly, allowing the pressure roller assembly 34 to cross obstacles smoothly. At the same time, two large pressure rollers 341 are arranged on the outermost sides. The large pressure rollers 341 have better obstacle-crossing ability (the larger the diameter of the pressure roller 340, the easier it is to cross obstacles), thereby further improving the obstacle-crossing ability of the pressure roller assembly 34 and reducing the impact on the edge of the photovoltaic panel component 4. Meanwhile, setting the middle pressure roller 340 as a small pressure roller 342 can save arrangement space, making the component arrangement more compact, and does not affect the obstacle-crossing ability of the pressure roller assembly 34.

[0048] like Figure 7 and Figure 8 As shown, in one embodiment, the drive assembly 3 further includes a roller assembly 36, which is located on one side of the sprocket assembly 33 and between the sprocket assembly 33 and the pressure roller assembly 34. The roller assembly 36 includes a roller 360, which is horizontally arranged and rotatably connected to the mounting plate 31. The roller 360 is used to contact the side wall of the photovoltaic panel assembly 4.

[0049] Specifically, such as Figure 1 and Figure 2As shown, the photovoltaic panel module 4 is generally installed at an angle (i.e., the photovoltaic panel module 4 is installed at a certain angle to the horizontal plane). Therefore, the photovoltaic panel module cleaning device is also installed at an angle on the photovoltaic panel module 4. As a result, the drive component 3 will be subjected to a pulling force parallel to the tilting direction of the photovoltaic panel module 4 (tilting downward). Therefore, by setting the hanging wheel component 36 to contact the side wall of the photovoltaic panel module 4, a lateral pulling force is provided to prevent the photovoltaic panel module cleaning device from sliding downward along the surface of the photovoltaic panel module 4 and causing the position to shift. At the same time, the hanging wheel component 36 can also further make the photovoltaic panel module cleaning device move more smoothly and improve the walking ability of the photovoltaic panel module cleaning device.

[0050] like Figure 7 and Figure 8 As shown, in one embodiment, there are multiple rollers 360, which are arranged sequentially along the moving direction of the drive assembly 3. The multiple rollers 360 are flush with each other (on the same plane) at the end near the photovoltaic panel assembly 4. The multiple rollers 360 include two large rollers 361 and at least one small roller 362, with the at least one small roller 362 located between the two large rollers 361. The two large rollers 361 have the same outer diameter, and the outer diameter of the small roller 362 is smaller than that of the large rollers 361.

[0051] Specifically, in this embodiment, there is one small pulley 362 (of course, in other embodiments, the number of small pulleys 362 can be set to more according to actual needs). This small pulley 362 is located between two large pulleys 361, that is, the two large pulleys 361 are located on the outermost side of the pulley assembly 36.

[0052] This embodiment employs multiple rollers 360. When the roller assembly 36 crosses obstacles such as gaps or steps between photovoltaic panels 4, the foremost roller 360 contacts the obstacle first and its position shifts, while the other rollers 360 remain in contact with the surface of the photovoltaic panel 4 (at least two rollers 360 remain in contact with the surface of the photovoltaic panel 4). This ensures that the overall posture of the roller assembly 36 remains unchanged or only slightly changed, allowing it to smoothly cross obstacles. Simultaneously, two large rollers 361 are positioned on the outermost sides. Larger rollers 361 have better obstacle-crossing capabilities (the larger the diameter of the roller 360, the easier it is to cross obstacles), further enhancing the obstacle-crossing ability of the roller assembly 36 and reducing impact on the edges of the photovoltaic panel 4. Furthermore, using a smaller roller 362 in the middle position saves space, allowing for a more compact component arrangement without affecting the obstacle-crossing ability of the roller assembly 36.

[0053] like Figure 9 and Figure 10As shown, in one embodiment, the sprocket assembly 33 also includes a drive shaft 334, one end of which is fixedly connected to the center of the drive sprocket 332, and the other end of which is fixedly connected to the drive shaft 321 of the drive device 32.

[0054] like Figure 9 and Figure 10 As shown, in one embodiment, the sprocket assembly 33 also includes a driven shaft 335, one end of which is rotatably connected to the center of the driven sprocket 333, and the other end of which is fixedly connected to the mounting plate 31.

[0055] In one implementation, the drive device 32 is an electric motor.

[0056] like Figure 3 and Figure 4 As shown, in one embodiment, the mounting plate 31 is located on one side of the traveling beam 11, the sprocket assembly 33 is located between the mounting plate 31 and the traveling beam 11, and the mounting plate 31 is connected to the end of the traveling beam 11.

[0057] like Figure 3 , Figure 4 and Figure 13 As shown, in one embodiment, the end of the traveling beam 11 is provided with a connecting rod 12. One end of the connecting rod 12 is connected to the end of the traveling beam 11, and the other end of the connecting rod 12 passes through the sprocket assembly 33 and is connected to the mounting plate 31.

[0058] like Figure 4 and Figure 7 As shown, in one embodiment, the driving sprocket 332 and the driven sprocket 333 are spaced apart in the transmission belt 331. The connecting rod 12 passes through the gap between the driving sprocket 332 and the driven sprocket 333 in the transmission belt 331 and is connected to the mounting plate 31, which makes the arrangement of the connecting rod 12 more reasonable and saves arrangement space.

[0059] like Figure 3 , Figure 4 and Figure 13 As shown, in one embodiment, a tongue plate 311 is provided on the side of the mounting plate 31 away from the traveling beam 11. The tongue plate 311 extends and protrudes from the side wall of the mounting plate 31. One end of the connecting rod 12 is connected to the traveling beam 11, and the other end of the connecting rod 12 passes through the sprocket assembly 33 and the mounting plate 31 and is connected to the tongue plate 311.

[0060] Specifically, in this embodiment, a tongue plate 311 is provided on the mounting plate 31 and positioned on the side of the mounting plate 31 away from the traveling beam 11. This allows the tongue plate 311 and the mounting plate 31 to participate in the force distribution simultaneously, thus improving the lifespan of the tongue plate 311 and the mounting plate 31 and reducing the tendency of the drive assembly 3 to overturn (if the tongue plate 311 is located on the side of the mounting plate 31 closer to the traveling beam 11, the traveling beam 11 will exert a pulling force on the mounting plate 31, and the force on the mounting plate 31 will be concentrated on the side closer to the traveling beam 11, thereby increasing the possibility of the drive assembly 3 overturning towards the side closer to the traveling beam 11).

[0061] like Figure 4 and Figure 7 As shown, in one embodiment, the connecting rod 12 passes through the gap between the driving sprocket 332 and the driven sprocket 333 in the transmission belt 331 and is connected to the tongue plate 311.

[0062] like Figure 13 and Figure 14 As shown, in one embodiment, the mounting plate 31 has a through hole 312 at the position corresponding to the tongue plate 311, and the connecting rod 12 passes through the through hole 312 and is connected to the tongue plate 311.

[0063] like Figure 13 and Figure 14 As shown, in one embodiment, the mounting plate 31 is also provided with a reinforcing rib 314 connected to the tongue plate 311, thereby improving the stress resistance of the tongue plate 311.

[0064] like Figure 13 and Figure 14 As shown, in one embodiment, the tongue plate 311 and the mounting plate 31 are an integral structure.

[0065] like Figure 13 and Figure 14 As shown, in one embodiment, the drive assembly 3 also includes a connecting pin 37. The tongue plate 311 has a first through hole 313, and the end of the connecting rod 12 has a second through hole 121. The connecting pin 37 is inserted into both the first through hole 313 and the second through hole 121, thereby connecting the connecting rod 12 to the tongue plate 311. The connecting pin 37 can be a bolt, etc.

[0066] like Figure 13 and Figure 14 As shown, in one embodiment, there are two tongue plates 311, which are arranged vertically at intervals, and the end of the connecting rod 12 is inserted between the two tongue plates 311.

[0067] like Figures 3 to 6As shown, in one embodiment, the drive assembly 3 includes a first drive assembly 3A and a second drive assembly 3B, which are respectively disposed at both ends of the traveling beam 11. The first drive assembly 3A is disposed at the upper end of the traveling beam 11, and the second drive assembly 3B is disposed at the lower end of the traveling beam 11. Connecting rods 12 are provided at both opposite ends of the traveling beam 11. One end of the connecting rod 12 is connected to a tongue plate 311 on the mounting plate 31 of the first drive assembly 3A, and the other end of the connecting rod 12 is connected to a tongue plate 311 on the mounting plate 31 of the second drive assembly 3B.

[0068] like Figure 5 and Figure 6 As shown, in one embodiment, the traveling beam 11 includes two side beams 111 and two crossbeams 112. The two side beams 111 are arranged in parallel and spaced apart. The crossbeams 112 are located between the two side beams 111, and the two ends of the crossbeams 112 are connected to the two side beams 111 respectively.

[0069] like Figure 5 and Figure 6 As shown, in one embodiment, there are multiple crossbars 112, which are arranged sequentially at intervals along the length of the side beams 111. Each crossbar 112 is connected to two side beams 111 at both ends. This embodiment forms the basic frame of the walking beam 11 by setting multiple crossbars 112 connected to two side beams 111 respectively. This not only results in a simple structure but also a stable structure, which can meet the high-strength requirements of the walking beam 11.

[0070] like Figure 5 and Figure 6 As shown, in one embodiment, the crossbar 112 includes an end connecting crossbar, which is provided at the end of the side beam 111, and the connecting rod 12 is connected to the end connecting crossbar.
