The method comprises the following steps:
the following is the working process of the reciprocating hammer assembly:
when the steel plate 4 is placed on the auxiliary bearing plate 2 in use, the steel plate 4 is driven by the conveying wheels 3 at two sides to move rightwards, and the first beating body 504 and the second beating body 508 can carry out beating repair on sand holes and slag holes on the surfaces of the steel plate 4 in the moving process, and the concrete working process is as follows:
the cam 502 moves downwards against the first downward moving column 503 under the drive of the motor, the first downward moving column 503 moves upwards with the assistance of the guide hole on the fixed plate 501, the first beating body 504 connected with the bottom end is used for beating the lower steel plate 4, when the first downward moving column 503 moves downwards, the first downward moving column 503 moves upwards with the assistance of the driving rod 505 connected with the shaft rod 506, the moving second downward moving column 507 moves upwards with the second beating body 508, the first downward moving column 503 is not contacted by the cam 502 any more along with the continuous rotation of the cam 502, the second downward moving column 507 which is driven to indirectly rise by the driving rod 505 can move downwards under the action of the gravity of the second beating body 508 and beat the steel plate 4, meanwhile, in the process, the first downward moving column 503 which is driven to move downwards can rise again under the assistance of the driving rod 505 and the shaft lever 506, namely, the first beating body 504 and the second beating body 508 can intermittently beat the steel plate 4 below by the rotation of the cam 502 so as to seal sand holes and slag holes;
the above working process is shown with reference to fig. 1 to 4.
The following is the working process that the hole detection subassembly includes:
furthermore, if the steel plate 4 has no larger sand holes and slag holes, the roller 608 rolls on the steel plate 4, if the steel plate 4 has larger sand holes 401, the column cavity 601 will move downward under the action of the elastic force of the first spring 603 when the column cavity 601 coincides with the sand holes 401, the anti-deflection rod 604 cooperates with the holes on the auxiliary piece 602 to make the downward movement of the column cavity 601 as vertical as possible, the pull wire 612 on the auxiliary piece 602 will be pulled downward, the sleeve ring 607 sleeved with the roller 608 will be pushed downward by the second spring 609 reset under the assistance of the cross rod 606 at this time due to the action of the steel plate 4, when the sleeve ring 607 moves downward, the sleeve ring 607 will move downward in the vertical channel 605 with the cross rod 606 thereon, at this time, the second electric contact body 611 on the cross rod 606 gradually approaches and contacts with the contact point on the first electric contact body 610 in moving, when the first electric contact body 610 contacts with the second electric contact body 611, the driving gear 705 electrically connected with the first electric contact body 610 rotates under the driving of the motor, and meanwhile, the start-stop controller 614 controlling the rotation of the conveying wheel 3 also stops conveying the steel plate 4 by the conveying wheel 3, at this time, hole detection work is finished, that is, no matter where position the sand hole 401 on the steel plate 4 is located through the arrangement of the column cavity 601 and the first spring 603, the column cavity 601 can be inserted into the sand hole 401 through the assistance of the first spring 603 as long as the position exists, compared with a manual searching mode, the method can avoid the influence of the sand hole which is not found on the service life of the whole material, and meanwhile, the method is more beneficial to repairing work after the sand hole is found, and the accuracy and the efficiency are far higher than that of manual work;
furthermore, it is known that, because the cylindrical cavity 601 is adapted to the hole 401 when in use, the cylindrical cavity 601 is inserted into the hole 401 with the indirect assistance of the first spring 603 only when the hole 401 is larger than the cylindrical cavity 601, so that the diameter of the cylindrical cavity 601 can be changed according to the size of the hole 401, thereby adapting to different detection standards and having wider applicability;
furthermore, by the arrangement of the first spring 603 and the roller 608, the column cavity 601 can be assisted to move on the surface of the steel plate 4 when the steel plate 4 moves, so that the situation that the sand holes and slag holes on the steel plate 4 are contacted with the bottom surface of the column cavity 601 to generate friction or even prevent the steel plate 4 from moving and the bottom surface of the column cavity 601 from being damaged when the steel plate 4 moves is avoided;
further, after the column cavity 601 is inserted into the eyelet 401 under the indirect action of the first spring 603, if the column cavity 601 is to be removed from the eyelet 401, the whole device is enabled to continue to operate, the column cavity 601 is pulled upwards by the pulling wire 612 through the auxiliary piece 602 as long as the corresponding pulling wire 612 on the side wall of the main body supporting plate 1 is pulled, and then the second start switch 613 in electrical connection with the conveying wheel 3 is pressed, at this time, the conveying wheel 3 drives the steel plate 4 to move again until the hole detection operation is completed;
please refer to fig. 1, 2, 5-10 and 12 for the above operation.
The following is the working process of the reaming assembly:
further, when the downward moving post cavity 601 is finally inserted into the sand hole 401 under the action of the elastic force of the first spring 603, the outward expansion body 704 and the sand hole 401 are located on the same horizontal plane, because the first electric contact body 610 and the second electric contact body 611 are in contact with each other, the driving gear 705 electrically connected with the first electric contact body and the second electric contact body can rotate with the driven gear 707 during rotation, the rotating driven gear 707 can move the sliding post 709 sliding therein under the assistance of the auxiliary through groove 708, the sliding post 709 can move outward with the outward expansion body 704 in the moving channel 703 during movement, so that the irregular sand hole 401 is reamed, that is, by the arrangement of the outward expansion body 704, the reaming operation can be directly performed after the hole detection, the subsequent missing problem caused by the fact that the reaming operation is not directly performed during the hole detection can be effectively avoided, and the hole detection and the matching of the reaming operation can maximize the efficiency.
The above operation is described with reference to fig. 6, 9, 11, and 12-14.
The method is as follows:
can beat the sand hole on steel board 4 surface, the slag hole through the setting of first beating body 504, second beating body 508 to this seals the processing, be different from the mode of manual beating, efficiency is higher and repair effect is better relatively, steel board 4 that is beaten simultaneously can be by carrying out follow-up hole detection, if still there is great sand hole, slag hole on the steel board 4, the post cavity 601 just can be by first spring 603 support into sand hole 401, and carry out reaming through outer expanding body 704, avoid appearing looking for the mode of sand hole through the manual work and appear neglecting, the life of the sand hole messenger whole material that is neglected, not repaired reduces, the condition of the best effect of repair can not be reached in this appearance.
