[0043] The tearing part 200 includes a frame assembly 201 fixed to one side of the collecting hopper 101, and a winding assembly 202 for cleaning the ceramic gasket is installed on the frame assembly 201.

[0044] Further, the frame assembly 201 includes a support 201a, one end of the support 201a is fixed to the upper side of one end of the collecting hopper 101, the other end of the support 201a is rotatably connected with a guide roller 201b, a shovel 201c is arranged at the position of the one end of the support 201a corresponding to the guide roller 201b, and a window 201d is arranged on the other side of the support 201a.

[0045] Further, the winding assembly 202 includes a fixed seat 202a fixed to one side of the support 201a and corresponding to the position of the window 201d, one side of the fixed seat 202a is rotatably connected with a winding roller 202b, the other side of the fixed seat 202a is rotatably connected with a connecting rod 202c, and the other end of the connecting rod 202c is rotatably connected with a roller 202d.

[0046] Further, the rotating shaft of the roller 202d penetrates the connecting rod 202c and is fixed with a belt pulley one 202e, the rotating shaft of the winding roller 202b penetrates the fixed seat 202a and is fixed with a belt pulley two 202f, and the belt pulley one 202e and the belt pulley two 202f are driven by a belt 202g.

[0047] Further, an elastic member 202h is arranged on the side surface of the connecting rod 202c, and the other end of the elastic member 202h is connected to the side surface of the support 201a.

[0048] Specific, elastic member 202h includes hydraulic rod and buffer spring, the fixed end and telescopic end of hydraulic rod are installed with connecting ring, connecting ring is installed with rotating pin, two rotating pins are installed on the inclined plane of connecting rod 202c and the side of support 201a respectively, although the surface of steel plate looks flat, but there will be a certain middle wave, edge wave or edge, of course, this needs to be within the scope of the specified unevenness, therefore, when the roller 202d passes through the middle wave, edge wave or edge, under the tension of the hydraulic rod and the buffer spring, the connecting rod 202c is driven to rotate as the fulcrum at the other end, in turn, the roller 202d can always adhere to the surface of the steel plate and roll.

[0049] Specific, the winding roller 202b is provided with the connecting belt 202i, one end of the connecting belt 202i is wound on the winding roller 202b, there is a gap between the shovel 201c and the guide roller 201b, for the passing of the connecting belt 202i, the other end of the connecting belt 202i is pasted with a rubber layer, the rubber layer can be fixed with one end of the adhesive tape at the bottom of the ceramic liner.

[0050] Operation process: when welding operation, the operator will paste the adhesive tape with ceramic liner on the bottom of the steel plate in advance, the center line of the ceramic liner corresponds to the gap of the weld;

[0051] When welding, the steel box girder welding safety auxiliary vehicle is placed under the steel plate, and corresponds to the weld, after placing, pull the connecting belt 202i to make the end with rubber layer of the connecting belt 202i and the end of the adhesive tape stick together, at this time, the welder welds the weld, and the remote controller is held by the controller far away to remotely control the operation of the driving motor 104, after the driving motor 104 operates, the driving wheel 102 rotates, because the wheel 102 is a strong magnet, in turn, it can realize driving on the bottom of the steel plate along the weld;

[0052] During the driving process, the roller 202d will also be passively rotated under the action of friction. After the roller 202d rotates, the pulley 202e is rotated, the pulley 202f is rotated through the transmission of the belt 202g, the pulley 202f drives the roller 202b to rotate, so that the connecting belt 202i is wound on the surface of the roller 202b and will also pull the adhesive belt. The adhesive belt will finally be wound on the roller 202b. The adhesive belt will pass through the guide roller 201b before being wound on the roller 202b. When the adhesive belt passes through the guide roller 201b, the angle of the adhesive belt will change. At this time, the adhesive belt can change the angle by adhering to the guide roller 201b because it is soft, while the ceramic liner cannot change the angle because it is hard, so the ceramic liner will tear off and fall into the collecting hopper 101. Some ceramic liners that are left on the adhesive belt will be pushed out by the shovel 201c and fall into the collecting hopper 101. The adhesive belt is finally wound on the roller 202b, so it can separate and collect the ceramic liner and the adhesive belt, which is convenient for subsequent processing, improves the recycling of the ceramic liner, reduces cost waste, and solves the problem of ceramic liner and slag falling caused by burning of the adhesive belt, object impact, fire and other accidents, and improves safety protection.

[0053] Embodiment 2

[0054] With reference to Figure 6 The difference between this embodiment and the first embodiment is that the tearing part 200 further comprises a tension adjusting assembly 203, which is installed between the frame assembly 201 and the winding assembly 202, and is used for adaptively adjusting the tension of the belt 202g.

[0055] The tension adjusting assembly 203 comprises a fixed plate 203a fixed to the inner side of the support 201a and a rack plate 203b adhered to the outer side of the connecting rod 202c. The upper end of the rack plate 203b is fixed below one end of the fixed plate 203a, and one side of the rack plate 203b is engaged with a gear 203c. One side of the gear 203c is fixed with an adjusting rod 203d, and the other end of the adjusting rod 203d is rotatably connected with an adjusting wheel 203e.

[0056] Specifically, the rack plate 203b is arc-shaped, and when the connecting rod 202c rotates in a circle, the gear 203c can be fully engaged with the rack plate 203b. When the middle wave, the edge wave or the edge of the steel plate surface is warped, the roller 202d is always rolled on the surface of the steel plate under the driving of the elastic member 202h. When the connecting rod 202c moves downward, the distance between the pulley one 202e and the pulley two 202f becomes close, so the belt 202g will be loose and affect the transmission effect. At this time, the gear 203c rotates along the rack plate 203b during the downward movement of the connecting rod 202c, which drives the adjusting rod 203d to rotate, so that the adjusting wheel 203e abuts against the belt 202g from the inside. At this time, the adjusting wheel 203e, the pulley one 202e and the pulley two 202f are in three-point contact, and the adjusting wheel 203e abuts against the belt 202g in the middle section, so that the belt 202g changes from a right-angled triangle to an isosceles triangle. Therefore, even if the distance between the pulley one 202e and the pulley two 202f becomes close, the effective tension is ensured under the action of the adjusting wheel 203e.

[0057] When the connecting rod 202c rotates upward, the distance between the pulley one 202e and the pulley two 202f becomes far. At this time, the gear 203c rotates in the opposite direction along the rack plate 203b, so that the belt 202g changes from a right-angled triangle to a linear shape. The adjusting wheel 203e does not contact the belt 202g, and the belt 202g can also ensure the transmission under the original tension, and will not have the problem of excessive stretching and loss of elasticity.

[0058] The remaining structures are the same as those in Embodiment 1.

[0059] Operation process: When the middle wave, the edge wave or the edge of the steel plate surface is warped, the roller 202d is always rolled on the surface of the steel plate under the driving of the elastic member 202h. When the connecting rod 202c moves downward, the distance between the pulley one 202e and the pulley two 202f becomes close, so the belt 202g will be loose and affect the transmission effect. At this time, the gear 203c rotates along the rack plate 203b during the downward movement of the connecting rod 202c, which drives the adjusting rod 203d to rotate, so that the adjusting wheel 203e abuts against the belt 202g from the inside. At this time, the adjusting wheel 203e, the pulley one 202e and the pulley two 202f are in three-point contact, and the adjusting wheel 203e abuts against the belt 202g in the middle section, so that the belt 202g changes from a right-angled triangle to an isosceles triangle. Therefore, even if the distance between the pulley one 202e and the pulley two 202f becomes close, the effective tension is ensured under the action of the adjusting wheel 203e.

[0060] When the connecting rod 202c rotates upward, the distance between the pulley one 202e and the pulley two 202f becomes far, at this time, the gear 203c rotates reversely along the rack plate 203b, so that the belt 202g changes from a right triangle to a linear, the adjusting wheel 203e does not contact the belt 202g, and the same can ensure that the belt 202g is driven under the original tension, and the problem of excessive stretching and loss of elasticity does not occur. The structure can adaptively adjust the tension of the belt 202g according to the stress of the roller 202d, ensure the effectiveness of the transmission, and avoid the problem that the cleaning effect is affected due to the stagnation of the winding action caused by useless transmission.

[0061] Embodiment 3

[0062] With reference to Figures 7-8 The difference between this embodiment and the above embodiments is that: the steel box girder welding safety auxiliary vehicle of the embodiment further comprises a cleaning part 300 installed above one side of the collecting hopper 101, used for reciprocating swing cleaning treatment of the steel box girder welding surface after the ceramic gasket is removed.

[0063] The cleaning part 300 comprises a mounting seat 301 fixed to the middle section of one side of the collecting hopper 101, and a mounting plate 302 fixed to one side of the mounting seat 301. A rotating shaft 303 is rotatably connected to the mounting seat 301 near the top end position, and a rotating roller 304 is fixed to one end of the rotating shaft 303. A row of steel brush hairs 305 are arranged on the outer periphery of the rotating roller 304. A driving assembly 306 for driving the rotating shaft 303 to reciprocate is installed on the mounting plate 302.

[0064] The driving assembly 306 comprises pin shafts 306a symmetrically fixed to the outer side of the rotating shaft 303 and a stepping motor 306b installed on the bottom of the mounting plate 302. A rotating frame 306c is rotatably connected to the pin shaft 306a. A fixed rod 306d is fixed to the bottom of the rotating frame 306c. The driving shaft of the stepping motor 306b vertically penetrates the mounting plate 302 and is fixed with a rotating disc 306e. A through groove 306f is formed in the inner side of the rotating disc 306e. An activity table 306g is slidably connected to the inner side of the through groove 306f. The stepping motor 306b drives the rotating disc 306e to rotate, and the rotating disc 306e drives the fixed rod 306d to make a deflection movement after rotating. By adjusting the position of the activity table 306g in the through groove 306f, the greater the deflection distance, the greater the swing amplitude. The fixed rod 306d rotates and drives the rotating roller 304 to rotate through the rotating frame 306c, so that the steel brush hairs 305 synchronously reciprocate to clean the bottom of the weld exposed after the ceramic gasket is removed.

[0065] Specific, rotating disc 306e is a tapered structure, through slot 306f is set on the tapered slope, the through slot 306f has a chute, the movable table 306g is fixed with the sliding block in the chute, and the sliding block can be locked by bolts. The bolts pass through the rotating disc 306e and abut against the sliding block of the movable table 306g. The movable table 306g adjusts the size of the eccentricity according to the position in the through slot 306f. The greater the deviation distance, the greater the swing.

[0066] The rest of the structure is the same as that of Example 2.

[0067] Operation process: the stepping motor 306b operates to drive the rotating disc 306e to rotate. The rotating disc 306e drives the fixed rod 306d to make a deviation movement after rotating. The greater the deviation distance, the greater the swing by adjusting the position of the movable table 306g in the through slot 306f. The fixed rod 306d rotates to drive the rotating frame 306c to rotate, so that the steel brush 305 synchronously reciprocates to clean the exposed weld seam bottom of the removed ceramic gasket, remove the splashed welding slag, improve the cleaning strength, and avoid safety hazards caused by falling welding slag with high temperature.
