Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel cleaning equipment transportation, and more specifically, to a photovoltaic panel cross-row transportation system. Background Technology

[0002] There are two main factors affecting the efficiency of photovoltaic power generation. The first is the daily sunshine conditions, and the second is the dust coverage on the surface of the photovoltaic panel. Dust and grit covering the surface of the photovoltaic panel will weaken the light intensity and affect the power generation efficiency of the photovoltaic panel. Therefore, it is necessary to clean the photovoltaic panel regularly to ensure its power generation efficiency.

[0003] Patent application CN114888021A discloses a cleaning device, a cleaning system, and a cleaning method for photovoltaic panels. It is applicable to the field of photovoltaic power generation technology. The technical solution is as follows: A cleaning device for photovoltaic panels, wherein the photovoltaic panels are fixedly installed on a photovoltaic panel mounting frame. A main guide rail and a secondary guide rail are fixedly installed at the upper and lower ends of the photovoltaic panel mounting frame along the length of the mounting frame, respectively. A cleaning device is slidably installed between the main guide rail and the secondary guide rail via a cleaning device traveling mechanism. A photovoltaic panel cleaning system is also disclosed, wherein a main guide rail guide rail for moving the cleaning device from the first set of photovoltaic panels to the second set is installed between the main guide rails of two sets of photovoltaic panels. A secondary guide rail guide rail is installed between the exit end of the secondary guide rail of the first set of photovoltaic panels and the entry end of the secondary guide rail of the second set of photovoltaic panels.

[0004] In the above scheme, the main guide rail is S-shaped and runs between the front and rear rows of photovoltaic panels to connect different sides of the front and rear rows of photovoltaic panels. The main guide rail is relatively long, and the cleaning equipment needs to travel a long distance on the main guide rail, which takes a long time and affects the cleaning efficiency of the photovoltaic panels. Utility Model Content

[0005] The present invention aims to overcome the defects of the prior art and provide a photovoltaic panel cross-row transfer system to solve the technical problem that the existing guide rails are S-shaped and run between the front and rear rows of photovoltaic panels, requiring the cleaning equipment to travel a long distance on the guide rails, which takes a long time and affects the cleaning efficiency of the photovoltaic panels.

[0006] The technical solution adopted by this utility model is a photovoltaic panel cross-row transfer system, including a connecting rail and a track transfer device; the connecting rail is located on the same side of the front row photovoltaic panels and the rear row photovoltaic panels, one end of the connecting rail is located above the front row photovoltaic panels, and the other end of the connecting rail is located above the rear row photovoltaic panels; the track transfer device is movably installed on the connecting rail and is used to move the photovoltaic panel cleaning equipment from the front row photovoltaic panels to the rear row photovoltaic panels via the connecting rail; guide mechanisms are respectively provided at both ends of the connecting rail, which enable the tilt angle of the photovoltaic panel cleaning equipment to be the same as the tilt angle of the photovoltaic panels.

[0007] The track-transfer device can move the photovoltaic panel cleaning equipment from the front row of photovoltaic panels to the rear row via a connecting rail. The cleaning equipment can then clean the rear row of photovoltaic panels. The connecting rail is located on the same side of both the front and rear rows of photovoltaic panels. The track-transfer device moves a short distance and takes less time, effectively increasing the speed of transporting the photovoltaic panel cleaning equipment and thus improving the cleaning efficiency. The guiding mechanism mainly changes the tilt angle of the photovoltaic panel cleaning equipment, adjusting it to match the tilt angle of the photovoltaic panels, thereby allowing for close contact and cleaning.

[0008] Furthermore, the track transfer device includes a main housing, sliding limit wheels mounted on the main housing, and a drive wheel. The sliding limit wheels are in rolling engagement with the connecting rail, and the drive wheel is in rolling engagement with the outer circumferential surface of the connecting rail. The drive wheel is driven to rotate by a drive structure installed inside the main housing. The sliding limit wheels can move on the connecting rail and will not detach from it, thus constraining the track transfer device to the connecting rail. The drive wheel provides power to the track transfer device through rotation, thereby enabling the track transfer device to move and run on the connecting rail.

[0009] Furthermore, a spring is installed on the main housing to push the drive wheel to press against the outer side of the connecting rail, thereby providing greater friction and preventing slippage.

[0010] Furthermore, the connecting rail has a U-shaped structure, with one end parallel to the top edge of the front row of photovoltaic panels and the other end parallel to the top edge of the rear row of photovoltaic panels. The parallel alignment of the connecting rail with the photovoltaic panels facilitates the movement of the photovoltaic panel cleaning equipment onto the panels.

[0011] Furthermore, the connecting rail has a circular cross-section; the guiding mechanism has the same orientation as the connecting rail, and the guiding mechanism is a guide plate, one end of which is connected to the side end of the photovoltaic panel and has the same inclination as the photovoltaic panel, while the other end is vertical. The circular cross-section connecting rail and guide plate are easy to manufacture and have low cost. The guide plate has a strong load-bearing capacity and can be used for photovoltaic panel cleaning equipment with large weight.

[0012] Furthermore, two sets of sliding limit wheels are correspondingly arranged on both sides of the main housing, with four wheels in each set. The four sliding limit wheels in each set are arranged in pairs opposite each other on both sides of the circular connecting rail. The outer circumferential surface of each sliding limit wheel is an arc-shaped surface that mates with the outer circumferential surface of the circular connecting rail. The arc-shaped surfaces of the pairs of opposing sliding limit wheels form bracket-shaped grooves, which can constrain the circular rail inside, thus preventing the track transfer device from falling off the connecting rail. Furthermore, the sliding limit wheels can roll on the connecting rail, allowing the track transfer device to move along the connecting rail.

[0013] Furthermore, the main housing is also equipped with auxiliary wheels, which roll in engagement with the outer surface of the circular connecting rail. The auxiliary wheels and the main housing are located on opposite sides of the connecting rail. Two auxiliary wheels are arranged in a figure-eight shape and fasten onto the connecting rail. The two auxiliary wheels form a figure-eight angle, allowing them to be fastened onto the connecting rail. The distance between the two auxiliary wheels is less than the diameter of the circular connecting rail, making it difficult for them to slip off the connecting rail. This provides a greater force and serves as a safety feature and assists in the movement of the rail-transferring device.

[0014] Furthermore, the connecting rail has a rectangular cross-section, and the guiding mechanism is an open slot along the connecting rail. The opening direction of the slot near the photovoltaic panel is the same as the tilt direction of the photovoltaic panel, gradually becoming more vertical as it moves away from the photovoltaic panel. The connecting rail is in a torsional state, and the track conveying device changes its tilt by adjusting the direction of the slot opening. Compared to a circular cross-section rail, a rectangular connecting rail requires an open slot, making manufacturing more difficult. The open slot has a lower load capacity, making it suitable for lightweight photovoltaic panel cleaning equipment. However, its structure is relatively simple and easy to install.

[0015] Furthermore, the sliding limit wheel is disposed within the opening groove and rolls in cooperation with the inner side of the opening groove of the connecting rail. Two sets of sliding limit wheels are respectively disposed on both sides of the main housing, with two wheels in each set. The track transfer device is connected to the sliding limit wheel via a shaft. The sliding limit wheel is disposed within the opening groove, and the shaft is connected to the track transfer device outside the opening groove through the opening of the opening groove. When the opening changes direction, the track transfer device also changes direction accordingly, thereby playing a guiding role. The sliding limit wheel is restricted within the opening and cannot be dislodged, thus the track transfer device is also suspended on the connecting rail.

[0016] Furthermore, the track-transfer device is equipped with a rotating mechanism to drive the photovoltaic panel cleaning equipment to rotate. This changes its orientation. After the photovoltaic panel cleaning equipment finishes cleaning the front row of photovoltaic panels, the track-transfer device moves the photovoltaic panel cleaning equipment from the front row to the rear row of photovoltaic panels via a connecting rail. During the movement, the track-transfer device can rotate the photovoltaic panel cleaning equipment to face the rear row of photovoltaic panels, thus enabling it to clean the rear row of photovoltaic panels after moving to them. When the track-transfer device does not have the function of rotating and adjusting the photovoltaic panel cleaning equipment, the transferred photovoltaic panel cleaning equipment still has a rotation function, and the track-transfer device can still achieve the transfer of the photovoltaic panel cleaning equipment.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: the track transfer device can transfer the photovoltaic panel cleaning equipment from the front row of photovoltaic panels to the rear row of photovoltaic panels via the connecting rail, so that the photovoltaic panel cleaning equipment can clean the rear row of photovoltaic panels. The connecting rail is set on the same side of the front row of photovoltaic panels and the rear row of photovoltaic panels. The track transfer device moves a short distance on the connecting rail and takes less time, which can effectively improve the speed of transferring the photovoltaic panel cleaning equipment, thereby improving the cleaning efficiency of the photovoltaic panels.

[0027] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0028] Example 1

[0029] like Figure 1-6 As shown, this embodiment discloses a photovoltaic panel cross-row cleaning system, including a photovoltaic panel cross-row transfer system and photovoltaic panel cleaning equipment. The photovoltaic panel cross-row transfer system includes a connecting rail 1 and a track transfer device 2. The photovoltaic panel cleaning equipment is a photovoltaic panel cleaning robot 3, or other photovoltaic panel cleaning equipment in the prior art. The photovoltaic panel cleaning robot 3 can move to clean the photovoltaic panels at the top of the photovoltaic panels. One end of the connecting rail 1 is set above one side of the front row of photovoltaic panels, and the other end of the connecting rail 1 is set above one side of the rear row of photovoltaic panels. The track transfer device 2 can move the photovoltaic panel cleaning robot 3 from the top of the front row of photovoltaic panels to the top of the rear row of photovoltaic panels through the connecting rail 1, so that the photovoltaic panel cleaning robot 3 can clean the photovoltaic panels across rows.

[0030] The connecting rail 1 is located on the same side of the front and rear photovoltaic panels, so the time taken for the rail transfer device 2 to move the photovoltaic panel cleaning robot from the front photovoltaic panel to the rear photovoltaic panel is short.

[0031] The connecting rail 1 has a U-shaped structure. One end of the connecting rail 1 is parallel to the top edge of the front row of photovoltaic panels, and the other end of the connecting rail 1 is parallel to the top edge of the rear row of photovoltaic panels.

[0032] Guide mechanisms 5 are provided at both ends of the connecting rail 1 to drive the photovoltaic panel cleaning robot 3 to tilt so that it has the same tilt angle as the photovoltaic panel, thereby enabling the photovoltaic panel cleaning robot 3 to move from the connecting rail 1 to the photovoltaic panel or from the photovoltaic panel to the connecting rail 1.

[0033] Specifically, the connecting rail 1 has a circular cross-section, i.e., circular connecting rail 1; the guiding mechanism 5 is a guide plate, which has the same orientation as the connecting rail 1. One end of the guide plate is connected to the side end of the photovoltaic panel and has the same inclination as the photovoltaic panel; it gradually twists from one end of the guide plate to the other end, and the other end of the guide plate is in a vertical state.

[0034] like Figure 1 As shown, although the U-shaped connecting rail 1 in this solution requires the rotation mechanism 4 to adjust its direction to achieve cross-row arrangement on the same side, the rotation mechanism 4 is not a necessary technical feature for achieving cross-row arrangement on the same side. Besides the aforementioned method of U-shaped connecting rail 1 cooperating with the rotation mechanism 4, other methods can also be used to achieve cross-row arrangement on the same side. For example, the connecting rail 1 can be set as a "V"-shaped rail, with the two bottom ends of the "V"-shaped rail equivalent to the two ends of the aforementioned connecting rail 1. After "head-to-tail interchange," the cross-row can move to the next row of photovoltaic panels (similar to the Zhan Tianyou V-shaped train track, a technique known to those skilled in the art, and will not be detailed here), or other methods, which will not be listed in detail here. In summary, this utility model aims to protect the method of cross-row arrangement on the same side to achieve the technical effects of shortening distance, shortening time, and improving efficiency.

[0035] The track transfer device 2 can be suspended on the connecting rail 1 and can transport the photovoltaic panel cleaning robot 3 on the connecting rail 1. The track transfer device 2 includes a main housing 9, a sliding limit wheel 10 and a drive wheel 11 installed on the main housing 9. The sliding limit wheel 10 rolls with the connecting rail 1 and can suspend the main housing 9 on the connecting rail 1. The drive wheel 11 is installed on the main housing 9 and rolls with the outer side of the connecting rail 1. The drive wheel 11 is driven to rotate by a drive structure installed inside the main housing 9 to provide power for the track transfer device 2. A spring 12 is installed on the main housing 9 to push the drive wheel 11 to press with the outer side of the connecting rail 1 to provide greater friction and prevent slippage.

[0036] Specifically, two sets of sliding limit wheels 10 are respectively provided on both sides of the main housing 9, with four wheels in each set, and they are arranged opposite each other on both sides of the circular connecting rail 1. The outer circumferential surface of the sliding limit wheels 10 is an arc-shaped surface that matches the outer circumferential surface of the circular connecting rail 1. The main housing 9 is also provided with auxiliary wheels 13, which roll in cooperation with the outer surface of the circular connecting rail 1. The auxiliary wheels 13 and the main housing 9 are located on opposite sides of the connecting rail 1, and there are two auxiliary wheels 13 that are fastened to the connecting rail 1 in a figure-eight shape.

[0037] The photovoltaic panel cleaning robot 3 includes a mobile device 14 and a cleaning device 15. The mobile device 14 includes a main unit housing 16, suspension wheels 17, and drive wheels 18. The suspension wheels 17 are fixed to the top of the main unit housing 16, and two are respectively arranged on both sides of the main unit housing 16, which roll in cooperation with the top edge of the photovoltaic panel. Two drive wheels 18 are respectively installed on both sides of the main unit housing 16, and the drive wheels 18 roll in cooperation with the surface of the photovoltaic panel. The main unit housing 16 is provided with a drive structure for driving the drive wheels 18 to rotate.

[0038] The track transfer device 2 can turn its cleaning surface to face the rear row of photovoltaic panels. When the track transfer device 2 moves the photovoltaic panel cleaning robot 3 from the front row of photovoltaic panels to the rear row of photovoltaic panels, it can adjust the cleaning surface of the photovoltaic panel cleaning robot 3 from facing the front row of photovoltaic panels to facing the rear row of photovoltaic panels. The cleaning surface of the photovoltaic panel cleaning robot 3 can then contact and clean the photovoltaic panel surface.

[0039] Specifically, the track transfer device 2 is equipped with a rotating mechanism 4, which is used to drive the photovoltaic panel cleaning robot 3 to rotate, so as to change the cleaning surface of the photovoltaic panel cleaning robot 3. When the track transfer device 2 moves from the front row of photovoltaic panels to the rear row of photovoltaic panels, the rotating mechanism 4 drives the photovoltaic panel cleaning robot 3 to rotate 180 degrees, so that the cleaning surface of the photovoltaic panel cleaning robot 3 is adjusted from facing the front row of photovoltaic panels to facing the rear row of photovoltaic panels.

[0040] It also includes a positioning mechanism 6, which includes a positioning contact 7 and a proximity switch 8. The positioning contact 7 is set on the connecting rail 1 between the two guide mechanisms 5, and the proximity switch 8 is installed on the track transfer device 2. The positioning contact 7 cooperates with the proximity switch 8. That is, when the track transfer device 2 moves to the position of the positioning contact 7, the proximity switch 8 detects the positioning contact 7, thereby controlling the rotating mechanism 4 to work and drive the photovoltaic panel cleaning robot 3 to rotate 180°, so that the cleaning surface of the photovoltaic panel cleaning robot 3 is adjusted from facing the front row of photovoltaic panels to facing the rear row of photovoltaic panels.

[0041] The drive structure that drives the drive wheel 11 to rotate and the drive structure that drives the power wheel 18 to rotate can be a geared motor, a servo motor, etc.

[0042] The photovoltaic panel cleaning robot 3 also includes an ultrasonic ranging sensor 20. Two ultrasonic ranging sensors 20 are installed on both sides of the main unit 16. The ultrasonic ranging sensors 20 are used to detect the surrounding environment to prevent the robot from falling due to missing photovoltaic panels or reaching the edge.

[0043] The cleaning device 15 includes a telescopic mechanism 21 and a cleaning mechanism 22. The telescopic mechanism 21 is mounted on the main unit 16, and the cleaning mechanism 22 is mounted on the telescopic mechanism 21. The telescopic mechanism 21 is used to drive the cleaning mechanism 22 to move along the width direction of the photovoltaic panel.

[0044] The cleaning mechanism 22 includes a roller frame 23, cleaning rollers 24, and a drive component 25. The cleaning rollers 24 are rotatably mounted on the roller frame 23. The cleaning rollers 24 are arranged side by side on the roller frame 23 along the length direction of the roller frame 23 (i.e., the width direction of the photovoltaic panel). The surface formed by the movement of the bottom side of the cleaning rollers 24 along the width direction of the photovoltaic panel is the cleaning surface. Multiple cleaning rollers 24 can be provided. Figure 6 Taking three as an example, the drive component 25 is set on the roller frame 23 in a one-to-one correspondence with the cleaning roller 24, and is used to drive the corresponding cleaning roller 24 to rotate. The drive component 25 can be a geared motor, servo motor, etc.

[0045] The telescopic mechanism 21 includes a scissor telescopic frame 26 and a second drive component 27. The scissor telescopic frame 26 has two ends, namely a first end and a second end. The first end of the scissor telescopic frame 26 is connected to the main unit housing 16, and the second end of the scissor telescopic frame 26 is connected to the roller frame 23. The second drive component 27 is used to drive the scissor telescopic frame 26 to extend and retract.

[0046] Each end of the scissor lift telescopic frame 26 has two connecting ends: a fixed end and a movable end. The length of the scissor lift telescopic frame 26 can be changed by altering the distance between the fixed end and the movable end. The fixed end of the first end of the scissor lift telescopic frame 26 is fixedly connected to the main unit housing 16, and the movable end is slidably connected to the main unit housing 16. The second drive component 27 is installed inside the main unit housing 16 and is used to drive the movable end of the first end of the scissor lift telescopic frame 26 to slide relative to the fixed end. The fixed end of the second end of the scissor lift telescopic frame 26 is fixedly connected to the roller frame 23, and the movable end of the second end of the scissor lift telescopic frame 26 is slidably connected to the roller frame 23. The second drive component 27 can be an existing electric telescopic rod, using a linear drive structure such as a motor, lead screw, and slider. Figure 5 Taking the lead screw and slider as an example, the slider is threadedly connected to the lead screw, and the sliding end of the first end of the scissor lift 26 is fixedly connected to the slider. The motor drives the lead screw to rotate, thereby driving the slider to slide. The slider drives the sliding end of the first end of the scissor lift 26 to move, thus realizing the extension and retraction control of the scissor lift 26.

[0047] When the drive wheels 18 on both sides come into contact with the photovoltaic panel, there is a gap 28 between the main unit 16 and the photovoltaic panel. This gap 28 allows the cleaning roller 24 near the main unit 16 to pass through, thereby cleaning the top edge of the photovoltaic panel.

[0048] The roller frame 23 is equipped with casters 19, which roll in conjunction with the photovoltaic panel to support the roller frame 23 and ensure that the cleaning roller 24 has a suitable cleaning distance from the photovoltaic panel, thereby improving the cleaning quality.

[0049] The rotating mechanism 4 includes a rotating shaft 29 and a driving component 30. The rotating shaft 29 is rotatably mounted on the photovoltaic panel cleaning robot 3, and the driving component 30 is mounted on the photovoltaic panel cleaning robot 3 to drive the rotating shaft 29 to rotate. One end of the rotating shaft 29 is fixedly connected to the track transfer device 2. Specifically, a support plate 31 is fixed on the main housing 9 of the track transfer device 2, and one end of the rotating shaft 29 is fixedly connected to the support plate 31. The rotating shaft 29 is rotatably mounted on the main housing 16 of the mobile device 14, and the driving component 30 is installed inside the main housing 16 of the mobile device 14 to drive the rotating shaft 29 to rotate. The driving component 30 can be a geared motor, a servo motor, etc.

[0050] Instructions for use: The photovoltaic panel cleaning robot 3 first moves and cleans the front row of photovoltaic panels. The photovoltaic panel cleaning robot 3 is suspended from the top edge of the front row of photovoltaic panels by the suspension wheel 17 and can move. The power wheel 18 provides power to move left and right on the photovoltaic panel. At the same time, the three drive components 1 25 drive the three cleaning rollers 24 to rotate and clean the photovoltaic panel. While cleaning left and right, the drive component 2 27 drives the scissor telescopic frame 26 to extend and retract, so that the cleaning rollers 24 move along the width direction of the photovoltaic panel, thereby completing the cleaning of the entire front row of photovoltaic panels.

[0051] After cleaning, the power wheel 18 provides power to move the photovoltaic panel cleaning robot 3 to the end of the photovoltaic panel. The circular connecting rail 1 extends between the two opposing sliding limit wheels 10. At the same time, the two auxiliary wheels 13 contact the circular connecting rail 1, and the drive wheel 11 contacts the circular connecting rail 1. The drive wheel 11 rolls on the side of the connecting rail 1 to provide power, so that the track transfer device 2 drives the photovoltaic panel cleaning robot 3 to move on the connecting rail 1. At the same time, the power wheel 18 rolls in cooperation with the guide plate, that is, the photovoltaic panel cleaning robot 3 cooperates with the guide plate. Under the action of the guide plate, as it moves, the photovoltaic panel cleaning robot 3 separates from the front row of photovoltaic panels and gradually rotates from the inclined direction to the vertical direction on the connecting rail 1.

[0052] When the robot moves to the proximity switch 8 and is opposite to the positioning protrusion 7, the drive component 30 drives the rotating shaft 29 to rotate, causing the moving device 14 and the cleaning device 15 to rotate, so as to turn the cleaning surface of the photovoltaic panel cleaning robot 3 so that it can face the rear photovoltaic panel when it moves to the rear photovoltaic panel. The robot stops when the cleaning surface of the photovoltaic panel cleaning robot 3 rotates 180°. This rotation can be performed while the track transfer device 2 moves on the connecting rail 1.

[0053] As the track transfer device 2 moves, the power wheel 18 gradually moves to the guide plate on the end side of the next row of photovoltaic panels. Under the action of the guide plate, as it moves, the moving device 14 and the cleaning device 15 gradually rotate to the same tilt angle as the next row of photovoltaic panels and move to the next row of photovoltaic panels. The track transfer device 2 disengages from the circular cross-section connecting rail 1. The photovoltaic panel cleaning robot 3 is suspended from the top edge of the next row of photovoltaic panels by the suspension wheel 17, completing the cross-row operation. Then, the power wheel 18 provides power to move left and right on the next row of photovoltaic panels. At the same time, the drive component 1 25 drives the cleaning roller 24 to rotate, and the drive component 27 drives the scissor telescopic frame 26 to extend and retract, so that the cleaning roller 24 moves along the width direction of the photovoltaic panel, thereby cleaning the entire surface of the next row of photovoltaic panels.

[0054] Example 2

[0055] like Figure 7 and 8 The difference between this embodiment and embodiment one is that in this embodiment, the cross-section of the connecting rail 1 is rectangular, and the guiding mechanism 5 is an open slot set along the connecting rail 1. The opening direction of the slot near the photovoltaic panel is the same as the tilt direction of the photovoltaic panel. As it moves away from the photovoltaic panel, the opening direction of the slot gradually becomes vertical. That is, the opening direction of the slot in the middle of the connecting rail 1 is vertical, and the entire connecting rail 1 is in a twisted state. The track transfer device 2 changes its tilt by changing the opening direction of the slot, thereby changing the tilt of the cleaning surface of the photovoltaic panel cleaning robot 3.

[0056] The track transfer device 2 includes a main housing 9, a sliding limit wheel 10 and a drive wheel 11 mounted on the main housing 9. The sliding limit wheel 10 rolls with the connecting rail 1 to suspend the main housing 9 on the connecting rail 1. The drive wheel 11 is mounted on the main housing 9 and rolls with the outer side of the connecting rail 1. A spring 12 is installed on the main housing 9 to push the drive wheel 11 to press against the surface of the connecting rail 1. The spring 12 ensures that the drive wheel 18 is always in contact with the outer side of the connecting rail 1 and forms a pressing fit with the outer side of the connecting rail 1 to provide greater friction and prevent slippage.

[0057] The track transfer device 2 cooperates with the opening slot. Specifically, in this embodiment, the sliding limit wheel 10 is set in the opening slot and connected to the main box 9 through the shaft. It rolls with the inner side of the opening slot of the connecting rail 1. Two sets of sliding limit wheels 10 are set on both sides of the main box 9, with two wheels in each set.
