Through the above operation, when the rolling wheel 907 is performing continuous conveying adjustment and detection status When the belt breaks and the belt is relatively quickly adjusted and moved in the continuous conveying adjustment detection state, the rolling wheel 907 is braked simultaneously to effectively reduce the impact of the belt on the hydraulic stepper pulling device and maintenance personnel. , causing excessive damage to the device and personnel, and based on the buffer shaft A, buffer shaft B and two sets of telescopic shafts 9087, spring A, and two-way meshing block 9088, two sets of meshing tooth sets 9061 distributed symmetrically around the center are set to respectively The belt is braked synchronously in two directions relative to each other, and the buffer shaft A and the buffer shaft B are elastically connected to the telescopic shaft 9087 through the spring A respectively, so that the two-way meshing block 9088 that cannot mesh in the opposite direction can have free movement and compression space. The reverse meshing gear set 9061 causes the two-way meshing block 9088 to toggle, causing the synchronous reduction. Because the toggle adjustment of the two-way meshing block 9088 synchronizes the adjustment of another set of two-way meshing blocks 9088, it is impossible to engage with the matching meshing gear set 9061 in time. moving situation.

It is worth emphasizing that the servo motor 1007 drives the screw rod 1006 to rotate so that the two sets of screw sleeves 1005 are relatively close and/or far away, so that the two sets of adjustment flip frames 901 pass through the stress groove 902, the transverse groove 1002 and the two groups located relatively on both sides. The cam force-loaded pull rod 1004 is relatively close to and/or unfolded, causing the driving assembly 903 to form a vertical extension adjustment state and a tilted embedded adjustment state, and the moving traction base 3 works through the stroke of the push-pull oil cylinder 503, and the splint beam B701 passes through the first working module 6. The second working module 7, at least one clamping cylinder 11 and the splint beam A601 move relatively close to form a rolling traction structure and/or a pinch-type traction structure that contacts the belt surface. The present invention is configured with a rolling traction structure and a pinch-type traction structure, so that the hydraulic step-by-step traction device can perform two different conveying operations: the first focused and detailed observation and maintenance operation before the belt is used, and the second quick review and observation and maintenance operation. Effectively, the hydraulic stepper pulling device is functional and practical.

Working principle: Install the fixed base 1 on the conveyor; then install the fixed traction guide frame 501 and the guide sleeve 502 in sequence; then install the static traction base 4 to the column end of the fixed traction guide frame 501 for fixation; then move the moving traction The seat 3 is installed on the guide sleeve 502; when the pinch-type traction work is carried out by focusing on the first careful inspection and maintenance operation before use; the return stroke of the clamping cylinder 11 located on the movable traction seat 3 causes the second work of the movable traction seat 3 The module 7 is lowered as shown in Figure 1 to clamp the belt, and then the stroke of the push-pull cylinder 503 causes the movable traction base 3 to hold the belt to move, and then the stroke of the clamping cylinder 11 located on the movable traction base 3 causes the second The working module 7 rises, and at the same time, the clamping cylinder 11 located on the static traction base 4 returns to work, causing the second working module 7 to descend, and then the push-pull cylinder 503 returns to reset and move the movable traction base 3, and this is achieved in a cyclic operation. For the intermittent adjustment work of the belt, the maintenance personnel observe the belt on the side and stop the work of the hydraulic stepper traction device at any time to repair the belt; when the second quick review and observation maintenance work is carried out rolling traction work, the servo motor 1007 drives the wire The rotation of the rod 1006 drives the sliding adjustment seat 1003 to move linearly, and the horizontal traction adjustment is performed through the inclined force-bearing groove 902 and the cam force-bearing pull rod 1004. In conjunction with the inclined setting of the force-bearing groove 902, the entire adjustment flip frame 901 can be rotated. Adjust so that the rotary drive movable contact part 9 protrudes; then the second working module 7 of the traction base 3 and the static traction base 4 is lowered through the clamping cylinder 11, causing the rolling wheel 907 to be in contact with the belt clamping, and then through The driving motor 905 drives the driving engagement seat 9073 to rotate as a whole, driving the rolling wheel 907 to rotate, so that the belt moves continuously. The maintenance personnel observe the belt and stop the hydraulic stepper pull device at any time to repair the belt, such as During continuous movement, the belt may be stretched and broken. The contact between the rolling wheel 907 and the belt can synchronously drive the rolling wheel 907 to accelerate rotation. When the rotating speed of the rolling wheel 907 exceeds the tension of the tension spring 90812, the combined centrifugal block 90811 is based on the center of gravity. Due to the deflection and rotational centrifugal force, the extruded part of the combined centrifugal block 90811 is in contact with the inclined force-bearing surface 9076, and the inclined force-bearing surface 9076 is used to force the axial movable sleeve 9089 to approach along the movable sleeve 90810 The drive motor 905 moves to one side, causing the movable sleeve 90810 to pull the angular shaft 9082 to rotate synchronously. The rotation of the angular shaft 9082 is adjusted to make the steering transmission block 9084 squeeze the radial transmission block 9085, buffer shaft A, and buffer shaft B. Spring A is used to synchronize Push the telescopic shaft 9087 respectively to cause the two-way meshing block 9088 to rotate, so that the one-way meshing protrusion meshes with the meshing gear set 9061 in the corresponding direction. Through the above operation, when the rolling wheel 907 is in the continuous conveying adjustment detection state, the reduction When the belt breaks and causes the belt to move relatively quickly in the continuous conveying adjustment detection state, the rolling wheel 907 is synchronously braked to effectively reduce the impact of the belt on the hydraulic stepper pull device and maintenance personnel, resulting in excessive equipment and personnel damage.
