DETAILED DESCRIPTION

[0047] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0048] In the present disclosure, it should be understood that the directions or positional relationships indicated by the directional words such as "length direction", "up-down direction" and "width direction" are defined based on the length direction, up-down direction and width direction of the track beam in normal use, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, specific directional structure and operation, and therefore cannot be understood as a limitation of the present disclosure. For details, please refer to Figure 1 and Figure 8 As shown. The terms "inside" and "outside" refer to the inside and outside of the corresponding structural contour. In addition, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another element and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0049] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0050] like Figures 1 to 11 As shown, the present disclosure provides a track line maintenance vehicle 100, including a vehicle body 1, a first locking structure 2 and a second locking structure 3, wherein the vehicle body 1 is used to move on a track beam 200, the first locking structure 2 is installed on the vehicle body 1, and the first locking structure 2 is configured to be able to clamp or release the track beam 200 along the up and down directions of the track beam 200, and the second locking structure 3 is installed on the vehicle body 1, and the second locking structure 3 is configured to be able to clamp or release the track beam 200 along the width direction of the track beam 200.

[0051] Through the above technical scheme, in the track line maintenance vehicle 100 provided by the present invention, since the first locking structure 2 can be clamped on the track beam 200 along the up and down directions of the track beam 200, the movement of the track line maintenance vehicle 100 in the up and down directions can be limited and the track line maintenance vehicle 100 can be prevented from sliding along the length direction of the track beam 200, and the second locking structure 3 can be clamped on the track beam 200 along the width direction of the track beam 200 (that is, the left and right direction of the track beam 200), so as to limit the swing of the track line maintenance vehicle 100 in the left and right directions and prevent the track line maintenance vehicle 100 from tilting or overturning. In addition, the second locking structure 3 can also prevent the track line maintenance vehicle 100 from sliding along the length direction of the track beam 200.

[0052] In other words, the vehicle body 1 can be locked on the track beam 200 of the track line through the first locking structure 2 and the second locking structure 3, and the first locking structure 2 and the second locking structure 3 can be clamped on the track beam 200 in different directions at the same time. The locking reliability of the track line maintenance vehicle 100 on the track beam 200 is high, which can effectively prevent the track line maintenance vehicle 100 from sliding, moving, tilting or even overturning during the maintenance process, and effectively ensure the safety of the operator.

[0053] When the track line maintenance vehicle 100 needs to be moved, the first locking structure 2 and the second locking structure 3 can be switched to the unlocked state. At this time, the vehicle body 1 can move relative to the track beam 200 of the track line, and the track line maintenance vehicle 100 can move to other positions on the track line, so that facilities at different positions on the track line can be inspected.

[0054] Optionally, in the track line maintenance vehicle 100 provided in the present disclosure, the track line maintenance vehicle 100 may also include a running mechanism 4 disposed on the vehicle body 1, so that the vehicle body 1 can move on the track beam 200. The running mechanism 4 may include running wheels 41 and an actuator (not shown in the figure) disposed at the bottom of the vehicle body 1, and the actuator is used to drive the running wheels 41 to rotate. In this way, the movement of the vehicle body 1 can be achieved by driving the running wheels 41 to rotate by the actuator. In other words, by driving the vehicle body 1 to move by the running wheels 41, the above-mentioned track line maintenance vehicle 100 can be moved to different positions on the track line according to the needs of maintenance, so that the operator can use the track line maintenance vehicle 100 to inspect different facilities on the track line.

[0055] It should be noted that the present disclosure does not limit the specific type of the above-mentioned actuator. As an implementation mode of the present disclosure, the above-mentioned actuator can be configured as a motor.

[0056] In addition, as an embodiment of the present disclosure, Figure 1 , Figure 4 , Fig. 9 and Fig.10 As shown, the number of the above-mentioned running wheels 41 can include two pairs of running wheels 41 arranged in pairs, wherein the two pairs of running wheels 41 are arranged at intervals in the length direction of the track beam 200 (i.e., the extension direction of the track beam 200), and the two running wheels 41 in each pair of running wheels 41 are arranged at intervals in the width direction of the track beam 200 (i.e., the width direction of the vehicle body 1).

[0057] In order to facilitate the movement of the track line maintenance vehicle 100 on the track line, optionally, as Figure 8 and Fig. 9As shown, the above-mentioned traveling mechanism 4 may further include traveling guide wheels 42 arranged at intervals along the width direction of the track beam 200, and a plurality of traveling guide wheels 42 are arranged at the lower part of the vehicle body 1 and are used to roll with the inner side wall of the track beam 200. In this way, when the vehicle body 1 moves, each traveling guide wheel 42 can roll on the inner side wall of the track beam 200, and the plurality of traveling guide wheels 42 can guide the vehicle body 1 to move along the length direction of the track beam 200 (i.e., the extension direction of the track beam 200).

[0058] It should be noted that the present disclosure does not limit how the first locking structure 2 specifically clamps the track beam 200. The first locking structure 2 can be directly clamped on the track beam 200 of the track line, and the first locking structure 2 can also be indirectly clamped on the track beam 200 of the track line. In other words, other structures can be further arranged between the first locking structure 2 and the track beam 200, such as the first mounting beam 5 mentioned below.

[0059] In addition, the present disclosure does not limit the specific position where the first locking structure 2 is clamped on the track beam 200. The first locking structure 2 can clamp the entire track beam 200 in the up and down directions, and the first locking structure 2 can also clamp a partial structure on the track beam 200 in the up and down directions.

[0060] As an embodiment of the present disclosure, Fig. 9 As shown, the upper end of the track beam 200 has a flange 201, and the first locking structure 2 includes a first locking member 21 and a second locking member 22, which are respectively arranged on the upper and lower sides of the flange 201 to clamp or release the flange 201.

[0061] In other words, the first locking structure 2 is clamped on a partial structure of the track beam 200 (i.e., the flange 201 at the upper end of the track beam 200), rather than on the entire track beam 200. When the first locking structure 2 is clamped on the track beam 200 of the track line, the first locking member 21 and the second locking member 22 can respectively abut against the flange 201 at the upper end of the track beam 200. On the one hand, the friction between the first locking member 21, the second locking member 22 and the flange 201 can lock and fix the vehicle body 1, effectively preventing the track line maintenance vehicle 100 from sliding along the track line during the maintenance process. On the other hand, if the vehicle body 1 tends to tilt during the maintenance process, the first locking member 21 and / or the second locking member 22 will squeeze the flange 201 as the vehicle body 1 tends to tilt, and the flange 201 reacts to the force of the first locking member 21 and / or the second locking member 22, which can limit the vehicle body 1, thereby effectively preventing the vehicle body 1 from tilting, shaking or even overturning.

[0062] The present disclosure does not limit the specific connection relationship between the first locking member 21 and the second locking member 22 and the vehicle body 1. As an embodiment of the present disclosure, Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the track line maintenance vehicle 100 also includes a first mounting beam 5, which is used to be arranged above the flange 201 and connected to the vehicle body 1, and the first locking member 21 can abut against the upper surface of the first mounting beam 5, and a first threaded hole is formed on the first locking member 21, and a first external thread is formed on the outer peripheral surface of the second locking member 22, one end of the second locking member 22 can movably pass through the first mounting beam 5 along the up and down direction of the track beam 200 and is threadedly connected to the first threaded hole, and the other end of the second locking member 22 is used to abut against the lower surface of the flange 201.

[0063] In other words, the first locking structure 2 is indirectly clamped to the track beam 200 of the track line through the first mounting beam 5. In this way, when the track line maintenance vehicle 100 moves to the position required for maintenance on the track line, the first locking member 21 and / or the second locking member 22 are rotated so that the second locking member 22 abuts against the lower surface of the flange 201 of the track beam 200, so that the first locking structure 2 can be locked to the track beam 200 of the track line. If the track line maintenance vehicle 100 needs to be moved, the first locking member 21 and / or the second locking member 22 are rotated so that the second locking member 22 is disengaged from the contact with the lower surface of the flange 201 of the track beam 200, so that the track beam 200 can be released from the first locking structure 2. The locking and unlocking operations of the first locking structure 2 on the track beam 200 are simple, which is conducive to improving the maintenance efficiency of the track line.

[0064] In addition, since the threaded connection itself has a self-locking function, when the second locking member 22 passes through the first mounting beam 5 and is threadedly connected to the first locking member 21, relative movement is not easy to occur between the first locking member 21 and the second locking member 22 connected by the threaded connection, and the first locking structure 2 is reliably locked on the track beam 200, effectively avoiding the relative movement between the first locking member 21 and the second locking member 22 during use, and the first locking member 21 and the second locking member 22 cannot be reliably clamped on the flange 201 of the track beam 200.

[0065] The present disclosure does not limit the specific positional relationship between the first mounting beam 5 and the flange 201 of the track beam 200 when the first locking member 21 and the second locking member 22 are clamped on the track beam 200. As an embodiment of the present disclosure, there is a first gap between the lower surface of the first mounting beam 5 and the upper surface of the flange 201. In this way, when the track line maintenance vehicle 100 needs to move, the first locking member 21 and the second locking member 22 can release the track beam 200. During the movement of the track line maintenance vehicle 100, there will be no direct contact between the lower surface of the first mounting beam 5 and the upper surface of the flange 201, which effectively avoids the friction between the lower surface of the first mounting beam 5 and the upper surface of the flange 201 of the track beam 200 when the track line maintenance vehicle 100 moves, and the first mounting beam 5 will interfere with the movement of the track line maintenance vehicle 100.

[0066] As other embodiments of the present disclosure, when the first locking member 21 and the second locking member 22 are clamped on the track beam 200, the lower surface of the first mounting beam 5 can be pressed against the upper surface of the flange 201. When the track line maintenance vehicle 100 moves to the position on the track line where maintenance is required, the installation position of the first mounting beam 5 on the vehicle body 1 can be adjusted so that the first mounting beam 5 is pressed against the upper surface of the flange 201 of the track beam 200, so that the first mounting beam 5 and the flange 201 are clamped between the first locking member 21 and the second locking member 22. When the track line maintenance vehicle 100 needs to move, the installation position of the first mounting beam 5 on the vehicle body 1 can be adjusted so that the first mounting beam 5 is out of contact with the flange 201 of the track beam 200, thereby avoiding the first mounting beam 5 from interfering with the movement of the track line maintenance vehicle 100.

[0067] It should be noted that the present disclosure does not limit how the second locking structure 3 is specifically clamped on the track beam 200. The second locking structure 3 can be directly clamped on the track beam 200 of the track line, or the second locking structure 3 can be indirectly clamped on the track beam 200 of the track line. For example, other structures can be arranged between the second locking structure 3 and the track beam 200.

[0068] In addition, the present disclosure does not limit the specific position where the second locking structure 3 is clamped on the track beam 200. The second locking structure 3 can be clamped on the entire track beam 200 along the width direction, or the second locking structure 3 can be clamped on a partial structure on the track beam 200 along the width direction.

[0069] As an embodiment of the present disclosure, Figure 5 and Figure 8As shown, the second locking structure 3 includes at least one pair of third locking members, which are respectively arranged on both sides of the track beam 200 along the width direction of the track beam 200, and are movably connected to the vehicle body 1 along the width direction of the track beam 200, and the third locking members are used to abut against the outer side wall of the track beam 200.

[0070] In other words, the second locking structure 3 is clamped to the entire track beam 200 in the width direction, that is, the paired third locking members are both located outside the outer side wall of the track beam 200, and abut against the outer side wall of the track beam 200 when clamping the track beam 200. On the one hand, the friction between the third locking member and the outer side wall of the track beam 200 can lock and fix the vehicle body 1, effectively preventing the track line maintenance vehicle 100 from sliding along the track line during the maintenance process. On the other hand, if the vehicle body 1 has a tendency to tilt during the maintenance process, the third locking member will squeeze the outer side wall of the track beam 200 under the tilting trend of the vehicle body 1, and the force of the outer side wall reacting to the third locking member can limit the vehicle body 1, thereby effectively preventing the vehicle body 1 from tilting, shaking or even overturning.

[0071] In other embodiments, one of the paired third locking members may be located on the outside of the outer wall of the track beam 200, and the other locking member may be located on the inside of the inner wall of the track beam 200; one of the paired third locking members is used to abut against the outer wall of the track beam 200, and the other locking member is used to abut against the inner wall of the track beam 200.

[0072] The present disclosure does not limit the specific connection relationship between the third locking member and the vehicle body 1. As an implementation method of the present disclosure, Figure 5 and Figure 8 As shown, the track line maintenance vehicle 100 also includes a second mounting beam 6, which is located on the outside of the track beam 200 and connected to the vehicle body 1, a second threaded hole is formed on the second mounting beam 6, and a second external thread is formed on the outer peripheral surface of the third locking member, and each third locking member passes through the second threaded hole on the corresponding second mounting beam 6 and is threadedly connected to the second threaded hole.

[0073] In other words, the third locking member can directly pass through the second mounting beam 6 and abut against the outer wall of the track beam 200. In this way, when the track line maintenance vehicle 100 moves to the position required for maintenance on the track line, the third locking member is rotated so that each third locking member abuts against the outer wall of the track beam 200, so that the second locking structure 3 can be locked to the track beam 200 of the track line. If the track line maintenance vehicle 100 needs to be moved, the third locking member is rotated so that the third locking member is out of contact with the outer wall of the track beam 200, and the track beam 200 can be released from the second locking structure 3. The locking and unlocking operations of the second locking structure 3 are simple, which is conducive to improving the maintenance efficiency of the track line.

[0074] In addition, since the threaded connection itself has a self-locking function, when the third locking member passes through the second threaded hole located on the second mounting beam 6 and presses against the outer wall of the track beam 200, the relative position between the third locking member and the second mounting beam 6 is not easy to change. In other words, the third locking member can always press against the outer wall of the track beam 200, and the second locking structure 3 is reliably locked on the track beam 200, which effectively avoids the situation in which the third locking member moves on the second mounting beam 6 during use and the third locking member cannot be reliably clamped on the track beam 200.

[0075] The present disclosure does not limit the specific positional relationship between the second mounting beam 6 and the outer side wall of the track beam 200. As an embodiment of the present disclosure, Figure 5 and Figure 8 As shown, there is a second gap between the side of the second mounting beam 6 close to the outer wall of the track beam 200 and the outer wall of the track beam 200. In this way, during the movement of the track line maintenance vehicle 100, the side of the second mounting beam 6 close to the outer wall of the track beam 200 will not directly contact the outer wall of the track beam 200, effectively avoiding the friction between the second mounting beam 6 and the track beam 200 when the track line maintenance vehicle 100 moves, and the second mounting beam 6 will interfere with the movement of the track line maintenance vehicle 100.

[0076] In order to realize the maintenance of facilities at different heights on the track line, it is optional to Figure 1 , Figure 2 , Figure 4 , Figure 8 as well as Fig.10As shown, the track maintenance vehicle 100 further includes a lifting bracket 7, a maintenance platform 8 and a driving mechanism 9. The maintenance platform 8 is mounted on the lifting bracket 7. The lifting bracket 7 is movably connected to the vehicle body 1 along the up and down direction of the track beam 200. The driving mechanism 9 is used to drive the lifting bracket 7 to move. In this way, by driving the lifting bracket 7 to move through the driving mechanism 9, the maintenance platform 8 can have different heights, thereby meeting the needs of maintenance of facilities at different heights on the track line, and the track maintenance vehicle 100 has good versatility.

[0077] The present disclosure does not limit the specific structure of the driving mechanism 9, as long as the driving mechanism 9 can meet the lifting requirements of the track line maintenance vehicle 100, optionally, Figure 8 and Fig. 9 As shown, the driving mechanism 9 includes a winch 91, a first pull rope 92 and a pulley assembly. The winch 91 is installed on the vehicle body 1, the first pull rope 92 is wound around the pulley assembly, the first end of the first pull rope 92 is connected to the winch 91, and the second end of the first pull rope 92 is connected to the vehicle body 1 or the lifting bracket 7. The winch 91 can reel in or release the first pull rope 92 to move the lifting bracket 7 upward or downward. By reeling in or releasing the first pull rope 92 by the winch 91, the position of the lifting bracket 7 on the vehicle body 1 can be adjusted, thereby adjusting the height of the maintenance platform, so that the operator can use the maintenance platform to inspect facilities at different heights on the track line.

[0078] It should be noted that the present disclosure does not limit the specific structure of the pulley assembly. As an embodiment of the present disclosure, Figure 2 As shown, the pulley assembly may include a first fixed pulley 931, the winch 91 is disposed at the lower part of the vehicle body 1, the first fixed pulley 931 is disposed at the upper part of the vehicle body 1, and the second end of the first pull rope 92 is connected to the lower part of the lifting bracket 7. In this way, by winding up the first pull rope 92 by the winch 91, the lifting bracket 7 can be moved in a direction away from the track beam 200 to increase the height of the maintenance platform. In addition, by releasing the first pull rope 92 by the winch 91, the lifting bracket 7 can be moved in a direction away from the track beam 200 to reduce the height of the maintenance platform.

[0079] As another embodiment of the present disclosure, Fig.11As shown, the pulley assembly may further include a first fixed pulley 931 and a second fixed pulley 932, the winch 91 is disposed at the lower part of the vehicle body 1, the first fixed pulley 931 is disposed at the upper part of the vehicle body 1, and the second fixed pulley 932 is disposed at the lower part of the lifting bracket 7, and from the first end of the first pull rope 92 to the second end of the first pull rope 92, the first pull rope 92 sequentially passes around the first fixed pulley 931 and the second fixed pulley 932, and the second end of the first pull rope 92 is connected to the upper part of the vehicle body 1. In this way, by retracting the first pull rope 92 by the winch 91, the lifting bracket 7 can also be moved in a direction away from the track beam 200 to increase the height of the maintenance platform, and in addition, by releasing the first pull rope 92 by the winch 91, the lifting bracket 7 can also be moved in a direction away from the track beam 200 to reduce the height of the maintenance platform.

[0080] In order to avoid the friction between the first pull rope 92 and the vehicle body 1, optionally, as Fig. 9 and Fig.11 As shown, the pulley assembly may further include a third fixed pulley 933, which is disposed at the lower portion of the vehicle body 1. From the first end of the first pull rope 92 to the second end of the first pull rope 92, the first pull rope 92 is passed around the third fixed pulley 933 and the first fixed pulley 931 in sequence. In other words, the first pull rope 92 is first passed around the third fixed pulley 933 and then passed around the first fixed pulley 931. In this way, during the movement of the lifting bracket 7, the first pull rope 92 and the vehicle body 1 will not rub against each other, which effectively avoids the mutual friction between the first pull rope 92 and the vehicle body 1, resulting in damage to the first pull rope 92 and / or the vehicle body 1, and the driving mechanism 9 cannot normally drive the lifting bracket 7 to move, and even affects the safety of the operator.

[0081] The present disclosure does not limit how to drive the winch 91 to rotate. As an implementation method of the present disclosure, Figure 6 and Fig. 9 As shown, the driving mechanism 9 further includes a rotating shaft 94, which is in transmission connection with the winch 91, and the driving mechanism 9 further includes a motor 95 connected to a first end of the rotating shaft 94 and / or a rotating handle 96 connected to a second end of the rotating shaft 94. In this way, the winch 91 can be driven to rotate by rotating the motor 95 or rotating the rotating handle 96, so that the winch 91 can retract or release the first pull rope 92, adjust the position of the lifting bracket 7 on the vehicle body 1, and then adjust the height of the maintenance platform.

[0082] To facilitate the rotation of the capstan 91, optionally, as Figure 6 and Fig. 9As shown, the driving mechanism 9 may further include a first gear 97 and a second gear 98, wherein the first gear 97 is mounted on the rotating shaft 94, and the second gear 98 is mounted on the winch 91 and meshes with the first gear 97, and the diameter of the first gear 97 is smaller than the diameter of the second gear 98. In other words, the first gear 97 and the second gear 98 can play a role of decelerating and increasing the distance of the rotating shaft 94, and only a small force is needed to drive the rotating shaft 94 to rotate, so as to drive the winch 91 to rotate, so that the winch 91 can reel in or release the first pull rope 92, effectively avoiding the situation that the sum of the weight of the lifting bracket 7 itself and the weight of the load of the maintenance platform is too large, the motor 95 and / or the rotating handle 96 cannot drive the winch 91 to rotate through the rotating shaft 94, and the height of the maintenance platform cannot be adjusted.

[0083] In order to improve the connection reliability between the lifting bracket 7 and the vehicle body 1, optionally, as Fig.11 As shown, the track line maintenance vehicle 100 further includes a fourth fixed pulley 10 and a second pull rope 20, the fourth fixed pulley 10 is arranged on the upper part of the lifting bracket 7, the first end of the second pull rope 20 is connected to the upper part of the vehicle body 1, and the second end of the second pull rope 20 is passed around the fourth fixed pulley 10 and connected to the lower part of the lifting bracket 7. In other words, the second pull rope 20 of the fourth fixed pulley 10 arranged on the upper part of the lifting bracket 7 is connected to the upper part of the vehicle body 1 at one end and connected to the lower part of the lifting bracket 7 at the other end, and can also play a role in pulling the lifting bracket 7. In other words, the lifting bracket 7 is pulled together by the first pull rope 92 and the second pull rope 20, and the connection between the lifting bracket 7 and the vehicle body 1 is reliable, which is also conducive to improving the smoothness of the movement of the lifting bracket 7 on the vehicle body 1.

[0084] Here, it should be noted that the present disclosure does not limit the specific connection position of the second pull rope 20 on the lifting bracket 7. As an embodiment of the present disclosure, the second end of the second pull rope 20 can be directly connected to the maintenance platform.

[0085] Alternatively, if Figure 1 , Figure 4 as well as Fig.10 As shown, there are multiple first pull ropes 92 and multiple pulley assemblies, and the multiple first pull ropes 92 are arranged one by one with the multiple pulley assemblies. The multiple pulley assemblies are arranged at intervals along the length direction or width direction of the track beam 200, and the first end of each first pull rope 92 is connected to the same winch 91. In other words, the lifting bracket 7 is pulled by the multiple first pull ropes 92 and the multiple pulley assemblies, the connection between the lifting bracket 7 and the vehicle body 1 is reliable, and the lifting bracket 7 moves smoothly on the vehicle body 1.

[0086] In order to prevent the lifting bracket 7 from swinging when the lifting bracket 7 moves on the vehicle body 1, as an embodiment of the present disclosure, Figure 4 and Figure 7As shown, the vehicle body 1 includes a vertical beam 11 extending in the up-down direction of the track beam 200, and a first guide wheel 71 and a second guide wheel 72 are provided on the lifting bracket 7. The first guide wheel 71 and the second guide wheel 72 are respectively provided on both sides of the vertical beam 11 and clamp the vertical beam 11, and the first guide wheel 71 and the second guide wheel 72 are in rolling contact with the vertical beam 11. In this way, the first guide wheel 71 and the second guide wheel 72 can guide and limit the lifting bracket 7, and effectively prevent the lifting bracket 7 from swinging during the movement. The first guide wheel 71 and the second guide wheel 72 in rolling contact with the vertical beam 11 of the vehicle body 1 are also conducive to reducing the friction between the lifting bracket 7 and the vehicle body 1, thereby helping to reduce the wear of the lifting bracket 7 and the vehicle body 1 during use, and prolonging the service life of the lifting bracket 7 and the vehicle body 1.

[0087] As another embodiment of the present disclosure, the vehicle body 1 may further include a vertical beam 11 extending in the up-down direction of the track beam 200, and the lifting bracket 7 has a guide groove 73, and the guide groove 73 is slidably matched with the vertical beam 11. The guide groove 73 can also guide and limit the lifting bracket 7, thereby effectively preventing the lifting bracket 7 from swinging during movement.

[0088] In order to improve the safety of track line maintenance, it is optional to Figure 8 , Fig.10 and Fig.11 As shown, the maintenance platform can also be provided with a guardrail 81. The guardrail 81 can protect the operator, thereby preventing the maintenance personnel from accidentally falling during the maintenance process, resulting in injuries to the maintenance personnel.

[0089] Optionally, the maintenance platform may be provided with a safety door 82, which is provided on one side of the maintenance platform and connected to the guardrail 81. The safety door 82 can facilitate the operator to get on and off, and on the other hand, the safety door 82 and the guardrail 81 can cooperate to protect the operator, thereby preventing the maintenance personnel from accidentally falling during the maintenance process, resulting in injuries to the maintenance personnel.
