[0002] The fillet weld cleaning machine can travel on the cylinder body and use the cutter head to clean the weld, making the welded surface smoother and more aesthetically pleasing. Most existing cleaning machines use multiple guide wheels and limit wheels to limit the cylinder ribs, and then the traveling wheels abut against the cylinder panel to allow the cutter head to travel on the cylinder surface and complete the cleaning operation.

[0003] However, since the plane of the rib is not a completely flat plane, there are obstacles during the movement. Since the guide wheel and the limit wheel are pressed against the plane of the rib, once an obstacle is encountered, the whole equipment will undulate with the amplitude of the obstacle, causing the cutter head to also undulate or vibrate, affecting the root cleaning effect of the cleaning surface.

[0004] Therefore, there is an urgent need to provide an obstacle-crossing device and a fillet weld cleaning machine to solve the problems existing in the prior art to a certain extent. Utility Model Content

[0011] The walking mechanism further comprises a mounting seat, the connecting shaft is connected with the mounting seat, and the guide wheel is rotationally connected with the mounting seat.

[0012] Specifically, the walking mechanism is two, the base is L-shaped and comprises a first mounting segment and a second mounting segment, and the two walking mechanisms are arranged on the first mounting segment and the second mounting segment respectively.

[0013] Further, the obstacle surmounting device further comprises a limiting mechanism, the limiting mechanism comprises a limiting seat and an adjusting assembly, one end of the limiting seat is connected with the adjusting assembly, the adjusting assembly is slidingly connected with the base, and the adjusting assembly can drive the limiting seat to move in the axial direction.

[0036] As Figure 1The utility model provides a kind of obstacle crossing device, including pedestal 1, walking mechanism 2 and locking assembly 3;Walking mechanism 2 includes guide wheel 201, positioning cylinder 204 and connecting shaft 203, guide wheel 201 is connected to one end of connecting shaft 203, the other end of connecting shaft 203 passes through pedestal 1 into positioning cylinder 204, and connecting shaft 203 is slidably connected with positioning cylinder 204;Positioning cylinder 204 is connected with pedestal 1, and positioning hole 2041 is formed on positioning cylinder 204, and the position of connecting shaft 203 corresponding positioning hole 2041 is formed with alignment hole 2032, locking assembly 3 can pass through positioning hole 2041 into alignment hole 2032, and the position of locking connecting shaft 203 relative to positioning cylinder 204.

[0037] Compared with the prior art, the obstacle crossing device provided by the utility model has the following advantages:

[0038] The obstacle crossing device provided by the utility model includes pedestal 1, walking mechanism 2 and locking assembly 3;Walking mechanism 2 includes guide wheel 201, positioning cylinder 204 and connecting shaft 203, guide wheel 201 is connected to one end of connecting shaft 203, the other end of connecting shaft 203 passes through pedestal 1 into positioning cylinder 204, and connecting shaft 203 is slidably connected with positioning cylinder 204;Positioning cylinder 204 is connected with pedestal 1, and positioning hole 2041 is formed on positioning cylinder 204, and the position of connecting shaft 203 corresponding positioning hole 2041 is formed with alignment hole 2032, locking assembly 3 can pass through positioning hole 2041 into alignment hole 2032, and the position of locking connecting shaft 203 relative to positioning cylinder 204.

[0039] From the analysis, it can be seen that the pedestal 1 can provide a mounting base for the walking mechanism 2, and the guide wheel 201 can realize the walking function of the obstacle crossing device and the overall angle weld root cleaning machine. Correspondingly, since the guide wheel 201 is connected to one end of the connecting shaft 203, and the other end of the connecting shaft 203 is slidably connected with the positioning cylinder 204, when the locking assembly 3 is not installed, the connecting shaft 203 can slide axially relative to the positioning cylinder 204, thereby driving the guide wheel 201 to move.

[0040] In actual application, the axis of the connecting shaft 203 in the present application extends in the vertical direction, so when the connecting shaft 203 moves in the vertical direction, it can simultaneously drive the guide wheel 201 to move in the vertical direction, so that when an obstacle is encountered, the guide wheel 201 can be lifted in the vertical direction by lifting the end of the connecting shaft 203 away from the guide wheel 201, thereby avoiding the obstacle and preventing the guide wheel 201 from following the obstacle and causing the cutter head to fluctuate, which affects the root cleaning effect of the cutter head.

[0041] When the obstacle is crossed, the positioning hole 2041 is formed on the positioning cylinder 204, and the alignment hole 2032 is formed on the connecting shaft 203, so that the relative position between the connecting shaft 203 and the positioning cylinder 204 can be locked by inserting the locking assembly 3 into the positioning hole 2041 and the alignment hole 2032, thereby ensuring the auxiliary guiding function of the guide wheel 201 on the whole device.

[0042] It should be noted that the pulling of the connecting shaft 203 and the insertion of the locking assembly 3 are both manually operated. However, the driving of the connecting shaft 203 can also be achieved by a motor and a screw rod cooperation structure, thereby realizing automatic operation.

[0043] Optionally, as shown in Figure 1 In combination with Figure 2 It is shown that the positioning cylinder 204 in the application is formed with a guide hole 2042 extending along the axial direction of the positioning cylinder 204, and the connecting shaft 203 is formed with a limiting pin 2031 corresponding to the guide hole 2042, and the limiting pin 2031 is located in the guide hole 2042.

[0044] Since the setting direction of the guide wheel 201 cannot be changed, the application forms a waist hole structure by opening the guide hole 2042 on the positioning cylinder 204 and extending the guide hole 2042 along the axial direction, so that the limiting pin 2031 formed on the connecting shaft 203 corresponding to the guide hole 2042 can limit the movement of the connecting shaft 203 in the axial direction and prevent the connecting shaft 203 from rotating in the circumferential direction, thereby avoiding the rotation of the guide wheel 201 affecting the positioning of the whole device.

[0045] Optionally, as shown in Figure 1 In combination with Figure 2 It is shown that the connecting shaft 203 in the application is formed with a holding portion 2033 at the end away from the guide wheel 201.

[0046] Preferably, the holding portion 2033 in the application is in the form of a circular ring for easy holding, and the end of the connecting shaft 203 is formed with a screw hole, and the end of the holding portion 2033 is formed with a screw rod portion, thereby realizing the detachable connection between the holding portion 2033 and the connecting shaft 203.

[0047] Optionally, as shown in Figure 1 In combination with Figure 2 It is shown that the locking assembly 3 in the application includes a locking piece 301 and a handle 302, the handle 302 is connected to one end of the locking piece 301, and the other end of the locking piece 301 can be inserted into the positioning hole 2041 and the alignment hole 2032 to lock the positions of the connecting shaft 203 and the positioning cylinder 204.

[0048] The locking piece 301 in the application is in a rod-shaped structure, the handle 302 is connected with the locking piece 301, and the locking piece 301 is convenient to pull and plug, and the rod-shaped structure of the locking piece 301 can be smoothly inserted into the positioning hole 2041 and the alignment hole 2032 to realize the position locking of the connecting shaft 203 and the positioning cylinder 204.

[0050] By making the diameter of the limiting part 3012 greater than the diameter of the insertion part 3011, the insertion of the insertion part 3011 can be ensured to be in place and stable.

[0057] The distance of limiting seat 401 relative to the contact surface can be adjusted by adjusting assembly 4. In actual operation, the guide wheel 201 is first pressed tightly on the guide plane of the rib, and then the adjusting assembly 4 is used to adjust the limiting seat 401, so that there is a certain gap between the limiting seat 401 and the guide plane. When the cylinder vibrates during operation, the limiting seat 401 can be used to limit the guide plane of the rib, thereby ensuring the stability of the operation.
