[0027] 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.
[0028] In the present disclosure, unless otherwise specified, "inside" and "outside" refer to the inside and outside of the contour of the corresponding component. Furthermore, the terms "first" and "second" used in the present disclosure are to distinguish one element from another and have no order or importance. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0029] according to Figures 1 to 3 As shown, an embodiment of the present disclosure provides an anti-falling structure for a boiler wall-climbing robot, which is used to prevent the wall-climbing robot 7 from falling; the anti-falling structure includes a guide member 2, a drive member 4 and a connecting member 3, the guide member 2 is used to be plugged into the fire viewing hole 110 of the boiler 1, the guide member 2 includes a guide structure, the drive member 4 is arranged on the outside of the boiler 1, one end of the connecting member 3 is used to connect with the wall-climbing robot 7, and the other end passes through the guide structure and is connected to the drive member 4, the guide structure is used to adjust the extension direction of the connecting member 3, and the drive member 4 is used to drive the connecting member 3 to drive the wall-climbing robot 7 to move toward the fire viewing hole 110, so that the wall-climbing robot 7 can be recovered when the inspection of the wall-climbing robot 7 is completed or when the wall-climbing robot 7 falls, the wall-climbing robot 7 can be pulled back through the connecting member 3.
[0030] Through the above technical scheme, a guide member 2 is provided to be inserted into the fire viewing hole 110 of the boiler 1, and the extension direction of the connecting member 3 is adjusted through the guide structure to prevent the connecting member 3 from contacting the inner wall surface of the boiler 1. The driving member 4 can realize the rapid recovery of the wall-climbing robot 7 and can adjust the length of the connecting member 3 according to the needs of actual conditions, so that the connecting member 3 and the guide member 2 cooperate with each other to prevent the wall-climbing robot 7 from accidentally falling and causing damage to the inner wall surface of the boiler 1 and the wall-climbing robot 7 itself. The anti-fall structure is used to improve the safety and reliability of the wall-climbing robot 7.
[0031] Optionally, the surface of the guide member 2 may be covered with a rubber film to protect the guide member 2 and prevent the guide member 2 from directly contacting the boiler 1 and causing wear to the boiler 1 .
[0032] In some possible implementations, for example, referring to Figure 1 and Figure 2 As shown, the guide member 2 may include a stopper 210 and a plug-in portion 220 connected to the stopper 210, the plug-in portion 220 is used to be plugged into the fire viewing hole 110, and the stopper 210 is used to prevent the plug-in portion 220 from moving toward the inside of the boiler 1, so that when the wall-climbing robot 7 falls accidentally, the stopper 210 can stop at the fire viewing hole 110 to prevent the wall-climbing robot 7 from falling to the bottom wall of the boiler 1. Or during the process of the wall-climbing robot 7 moving for inspection, the stopper 210 can effectively prevent the plug-in portion 220 from moving into the inside of the boiler 1, which is safer and more reliable.
[0033] In order to facilitate the plug-in portion 220 to adapt to the fire viewing holes 110 of different sizes, in some practicable manners, for example, reference Figure 1 and Figure 2 As shown, the cross-sectional area of the plug-in portion 220 in the direction away from the stop portion 210 can be gradually reduced. For example, the angle between the plug-in surface 221 of the plug-in portion 220 and the contact surface between the plug-in portion 220 and the stop portion 210 can be an acute angle, and the plug-in surface 221 is inclined toward the central axis M of the guide member 2. In this way, when the fire viewing holes 110 of different boilers 1 are of different sizes, the plug-in portion 220 can still be partially plugged into the fire viewing hole 110, which is more adaptable.
[0034] The structure of the plug-in portion 220 can be adaptively adjusted according to actual conditions, for example, the plug-in portion 220 can be configured as a truncated cone. The present disclosure does not specifically limit this, as long as the plug-in portion 220 can be adapted to fire viewing holes 110 of different sizes, those skilled in the art can make adaptive adjustments according to actual conditions.
[0035] In some possible implementations, for example, referring to Figure 1 and Figure 2 As shown, the guide structure may include at least one pulley 250 and a mounting groove 240 provided on the plug-in portion 220 and the stop portion 210 for mounting the pulley 250. The provision of the pulley 250 can effectively reduce the friction of the connecting member 3 and facilitate the rapid recovery of the wall-climbing robot 7.
[0036] In some possible implementations, for example, referring to Figure 1 and Figure 2As shown, the number of pulleys 250 can be two, and the two pulleys 250 can be at the same horizontal position, so that the driving member 4 can recover the connecting member 3 more quickly and the wall-climbing robot 7 can stretch the connecting member 3 more smoothly. The plug-in portion 220 and the stop portion 210 are both provided with wire grooves 230 for passing the connecting member 3. The wire grooves 230 can guide the connecting member 3 to improve the recovery efficiency of the connecting member 3. One end of the connecting member 3 is connected to the driving member 4, and the other end is arranged around the two pulleys 250 and connected to the wall-climbing robot 7.
[0037] Optionally, the connecting member 3 can be configured as a flexible member, for example, the connecting member 3 can be configured as a rope, so as to bend and adjust the direction through the guide structure. Of course, it is understandable that the driving member 4 can be configured as a winch, so as to recover the rope. This disclosure does not make specific limitations on this, and those skilled in the art can make adaptive adjustments according to actual conditions.
[0038] The limitation on the number of pulleys 250 and mounting slots 240 in the present disclosure is only for the present disclosure, and the number of pulleys 250 and mounting slots 240 can be adaptively adjusted according to actual conditions. For example, the number of pulleys 250 and mounting slots 240 can be four, and the two pulleys 250 located on the same plug-in portion 220 or stop portion 210 can be arranged in parallel along a horizontal direction perpendicular to the vertical direction. In this way, the wall-climbing robot 7 can be subjected to more uniform force during recovery.
[0039] In other feasible embodiments, in order to reduce the possibility of friction between the connecting part 3 and the wall surface of the plug-in part 220 caused by the wall-climbing robot 7 during the inspection process, the plug-in part 220 may include an avoidance space 260, and the avoidance space 260 is located on one side of the central axis M of the plug-in part 220. The avoidance space 260 is respectively connected to the mounting groove 240 and the interior of the boiler 1, so that when the wall-climbing robot 7 drives the connecting part 3 to move, it can obtain a larger moving distance and can reduce the possibility of friction between the connecting part 3 and the wall surface of the plug-in part 220.
[0040] Optionally, the wall surface of the installation groove 240 of the plug-in portion 220 facing away from the stop portion 210 may also be connected to the interior of the boiler 1, so that the wall-climbing robot 7 can obtain a larger moving area and prevent the connector 3 from rubbing against the wall surface of the installation groove 240 facing away from the stop portion 210.
[0041] Optionally, avoidance spaces 260 may be provided on both sides of the central axis M of the plug-in portion 220 , so that the positions of the avoidance spaces 260 do not need to be distinguished during use.
[0042] In some possible implementations, for example, referring to Figure 1 and Figure 2As shown, a pull-out handle 5 is provided on the side of the stopper 210 away from the plug-in portion 220 . For example, the pull-out handle 5 can be connected to the stopper 210 by welding to facilitate installation and removal of the guide member 2 .
[0043] In some possible implementations, for example, referring to Figure 1 As shown, the anti-fall structure may further include an anti-fall device 6, one end of which is connected to the connecting member 3, and the other end is connected to the wall-climbing robot 7. The anti-fall device 6 is used to prevent the wall-climbing robot 7 from falling too fast when it accidentally falls, and when the connecting member 3 is straightened for a moment, it swings left and right under the inertial impact and hits the side wall of the boiler 1.
[0044] The specific function and related structure of the fall arrester 6 can be retrieved and consulted by those skilled in the art in the art in the art, and the present disclosure will not elaborate on this.
[0045] Optionally, the surface of the fall arrester 6 may be covered with a rubber film to prevent the inner wall surface of the boiler 1 from being damaged when the fall arrester 6 contacts the inner wall surface of the boiler 1 .
[0046] It is understandable that the number of the anti-falling structures disclosed in the present invention can be adaptively adjusted according to actual conditions. For example, the number of the anti-falling structures can be two groups, and the two groups of anti-falling structures are respectively arranged at the two fire viewing holes 110 of the boiler 1, so that the forces on both sides of the wall-climbing robot 7 are balanced. The present invention does not make specific limitations on this, and those skilled in the art can make adjustments according to actual needs.
[0047] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0048] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0049] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
