The specific structure of the first adjusting part 14 and the second adjusting part 15 included in the telescopic adjusting part 13 during the use of the automatic hydraulic-jaw apparatus 10 has various implementations. As schematically shown in fig. 1 to 5, the present embodiment provides the following realizations for the first adjusting portion 14 and the second adjusting portion 15, respectively:

the first adjustment part 14 is specifically configured.

As schematically shown in fig. 1, 2 and 3, the first regulating portion 14 includes a first working plate 141 and a second working plate 142 arranged in parallel.

That is, the hydraulic cylinder 12, the first operating plate 141, the second operating plate 142, and the second adjusting portion 15 are all relatively movable, and the hydraulic clamp 11 and the second operating plate 142 are not relatively movable. Illustratively, the first end of the hydraulic cylinder 12 is connected to the first work plate 141 by a hinge assembly. Illustratively, the top of the first working plate 141 and the bottom of the second working plate 142 correspond to two sets of hinges, and the two sets of hinges enable the first working plate 141 and the second working plate 142 to be hinged with the second adjusting portion 15. At this time, the first and second working plates 141 and 142 and the second adjusting part 15 may constitute a polygonal structure, and the second adjusting part 15 moves left and right in the region between the first and second working plates 141 and 142.

As schematically shown in fig. 1 and 2, the first operating plate 141 is a steel plate formed integrally, a first end of the first operating plate 141 is rectangular, and a top of the first operating plate 141 is hinged to a first end of the hydraulic cylinder 12 and a bottom of the second adjusting portion 15 through a hinge set.

Illustratively, the second end of the first work plate 141 has a first opening 1411 for passage of piping or other components to be fitted to the hydraulic cylinder 11. Illustratively, the first opening 1411 is a U-shaped opening.

Illustratively, the first work plate 141 further includes flange apertures 1412 disposed about a circumference of the first opening 1411 for securing with pipes or other components passing through the first opening 1411. Illustratively, the flange holes 1412 are through holes with a diameter of 318 mm, and there are 10 through holes uniformly arranged on the circumference of the first opening 1411 for matching with the flanges on the christmas tree and bolting.

In the practical operation of the automatic hydraulic tong device 10, the hydraulic cylinder 12 needs to provide a large pushing force or pulling force to enable the hydraulic tong 11 to be in place or to be withdrawn, so that the first working plate 141 needs to bear and transmit the large pushing force or pulling force, which causes the first working plate 141 to be easily bent. As schematically shown in fig. 1, the first regulating portion 14 further includes a reinforcing rib 144.

The adjusting bolt is a component for connecting the main tong 111 and the back-up tong 112 of the hydraulic tong 11, and when the hydraulic tong 11 moves downward, the adjusting bolt moves downward at the same time.

In the practical operation of the automatic hydraulic tong device 10, since the pushing force or the pulling force provided by the hydraulic cylinder 12 needs to be transmitted through the telescopic adjusting part 13, if the structure of the telescopic adjusting part 13 is complicated, the pushing force or the pulling force provided by the hydraulic cylinder 12 is reduced in the transmission process, so that the force applied to the hydraulic tong 11 is different from the force applied to the hydraulic cylinder 12, and the position where the hydraulic tong 11 is in place or is withdrawn is relatively inaccurate.

illustratively, the top of the second working plate 142 is provided with at least one slotted hole 1424, the bottom of the third working plate 143 is provided with at least one protruding righting block, and the slotted hole 1424 is used for limiting the righting block. The long slot 1424 is a slot with a certain depth on the second working plate 142, and the centering block is a block structure protruding from the bottom of the third working plate 143, the setting position of the block structure is the same as the setting position of the slot, and the size of the block structure is smaller than that of the slot, so that the block structure can move in the slot within a small range. Illustratively, as shown in fig. 3, the top of the second work plate 142 is provided with three elongated slots 1424. Correspondingly, the bottom of the third working plate 143 is provided with three protruding centering blocks (not shown), and the three slotted holes 1424 correspond to the three centering blocks.

In order to realize the cooperation between the third working plate 143 and the second working plate 142, in the automatic hydraulic clamp apparatus 10 according to the embodiment of the present application, the second working plate 142 includes the second opening 1421, and the third working plate 143 includes the third opening 1431.

In addition, the second end of the hydraulic cylinder 12 is hinged to the cross beam in the middle of the rectangular structure formed by the second bracket 152, so that the hydraulic cylinder 12 and the second bracket 152 can move relatively through the hinged connection mode, and the force provided by the hydraulic cylinder 12 can be transmitted to the second bracket 152, thereby pushing the polygonal structure of the telescopic adjusting part 13 to change the shape or move one side relatively.

In use of the automatic hydraulic clamp apparatus 10, the relative positions of the first bracket 151 and the second bracket 152 may be appropriately restricted so that the relative positions of the first bracket 151 and the second bracket 152 do not change greatly. As schematically shown in fig. 5, the second adjusting portion 15 further includes a positioning assembly 153 for fixing the first bracket 151 and the second bracket 152. Illustratively, the positioning assembly 153 is fixedly disposed between the first bracket 151 and the second bracket 152.

Illustratively, the positioning assembly 153 includes a coupling shaft 1531 and a positioning nut 1532, the coupling shaft 1531 being threadably coupled to the positioning nut 1532. The connecting shaft 1531 sequentially penetrates through the first bracket 151 and the second bracket 152, and two ends of the connecting shaft 1531 are provided with threads adapted to the positioning nut 1532, so as to realize threaded connection between the connecting shaft 1531 and the positioning nut 1532.
