The following first describes a heavy idler device according to an embodiment of the present invention in detail with reference to the accompanying drawings.

As shown in fig. 1, according to the utility model discloses heavy bearing roller device for connect on stinger 100 through stinger backup pad 101 with bearing marine pipeline 600, stinger backup pad 101 includes two, and two stinger backup pads 101 control relatively setting on stinger 100 in vertical direction.

According to the utility model discloses heavy bearing roller device includes: the carrier 200 is associated with two idler units.

As shown in fig. 1, two ends of the carrier 200 are respectively connected to the stinger support plate 101.

The two carrier roller units are arranged at intervals in the front-rear direction and are respectively connected with the bearing device 200 so as to bear the marine pipeline 600 along the axial direction of the marine pipeline 600 by the two carrier roller units.

Therefore, the carrier roller is dispersed into two independent carrier roller units which are mutually connected and distinguished, so that each carrier roller unit can be adjusted according to the bending condition of the marine pipeline 600, the basic bearing state of the carrier roller supporting points in each carrier roller unit is improved, and the supporting points are stressed uniformly.

Further, the carrying device 200 includes: the load beam 201. The carrier beam 201 is formed in a U shape, the carrier beam 201 includes a beam main body horizontally disposed and connection portions respectively connected to both ends of the beam main body, and the carrier beam 201 is connected to the stinger support plate 101 through the connection portions.

Therefore, the height of the heavy carrier roller device can be adjusted by inserting and pulling the positioning pin 204 and changing the matching of the first pin hole 202 and the second pin hole 102 to lift/lower the carrier beam 201.

Further, the plurality of first pin holes 202 may be equally or unequally spaced and/or the distance between each of the plurality of first pin holes 202 may be different than the distance between each of the plurality of second pin holes 102. For example, if the plurality of first pin holes 202 are respectively arranged at intervals of 5mm, 10mm, 15mm, etc., as required, the height of the load beam 201 can be finely adjusted by determining the first pin holes 202 specifically matching with the second pin holes 102 according to the required height. Of course, the first pin holes 202 and the second pin holes 102 may be arranged at equal distances from each other, but the distance between the first pin holes 202 is different from the distance between the second pin holes 102, so that the specific height is determined by which of the first pin holes 202 and the second pin holes 102 is matched according to the required height. Of course, the first pin holes 202 may be arranged at intervals of 5mm, 10mm, 15mm, etc. without changing the existing distance between the first pin holes 202, such as 20mm, and the combination of the two can further adjust the height of the load beam 201 accurately to meet the requirements of pipes with different radii of curvature.

That is, each idler unit is relatively independent, in other words, the idler units may change position relatively independently when subjected to a force. From this, heavy bearing roller device can laminate the pipe wall of marine pipeline 600 better, effectively reduces contact pressure.

As shown in fig. 3, two balance beams 205 are pivotally connected to two ends of the carrier beam 201 and arranged along the left-right direction, two ends of the balance beam 205 are pivotally connected to the front and rear support seats 203, and two left and right ends of each support seat 203 are connected to the left and right balance beams 205.

As shown in fig. 3, two ends of the balance beam 205 are supported on the two supporting seats 203 through two lateral hinge points (or hinge point supports), respectively, and the middle of the balance beam is pivotally connected to the load-bearing beam 203 through a middle hinge point (or hinge point support). In other words, the balance beam 205 can rotate at the middle hinge point, and simultaneously, the two ends correspondingly drive the supporting seat 203 to adjust in the height direction, and because the connection between the two ends of the balance beam 205 and the supporting seat 203 is the pivot connection, the supporting seat 203 can be ensured to be in a natural suspension state in the vertical direction after adjustment, so that each carrier roller unit of the heavy carrier roller device can better fit with the pipe wall of the marine pipeline 600, and the marine pipeline 600 is prevented from being damaged.

Further, both ends of the load beam 201 are respectively provided with an angle limiting mechanism (not shown) for limiting a rotation angle of the balance beam 205. That is, the balance beam 205 is restricted from rotating only within a limited range by the angle restricting mechanism.

Wherein, the both ends of bearing roller 300 can be connected above the supporting seat through the bearing roller mount pad, for example. The specific mounting structure of the idler 300 is not particularly limited as long as it is possible to achieve that the idler 300 is rotatable above the support seat 203. From this, the marine pipeline 600 can be supported firmly to the bearing roller unit that four bearing rollers 300 formed, and in addition, two liang of a set of V font structure can be followed and control centre gripping marine pipeline 600, avoids the unexpected landing of marine pipeline 600.

That is, as shown in fig. 4, in the front-rear direction of each idler unit, 2 rotatable dumbbells having a thin middle and thick two ends are installed.

The guide roller 403 can play a guiding role when the cable is abandoned and recovered, so as to prevent the carrier roller 300 from being damaged, and can play a supporting role when a pipeline with small diameter is laid.

Further, one end of the guide roller support structure 401 (i.e., the connection end with the support base 203) is formed in a flange structure, which is vertically formed with a plurality of mounting holes through which the guide roller mounts 402 are mounted on the support base 203 by bolts. In addition, the mode of flange joint is adopted to facilitate the bolt pretension when the fixed carrier roller 300 is installed.
