Description

Technical Field

[0001] The utility model relates to the technical field of casing positioning, and more specifically, particularly relates to a long casing movable positioning frame suitable for high tides in the sea. Background Art

[0002] When inserting the casing, the floating crane lifts the casing vertically, and the other part is aligned with the guide frame for insertion. The current technology is to manually calibrate and lower it to the positioning pin first, and then use the positioning pin to position and lower it, which is time-consuming and laborious. Because the fixed distance between the fixed points is too narrow, the length of the casing gradually increases during the continuous lowering process during the high tide, and the resistance also gradually increases, causing the casing to tilt and shake. At the same time, because the floating crane also shakes to a certain extent with the waves, the casing becomes fixed in the middle, and the top and bottom shake irregularly, making it difficult to accurately align. In addition, the existing guide frame is a rectangular frame with insufficient structural strength, and it is easy to deform under high flow conditions. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 As shown, a long casing movable positioning frame suitable for high tide in the sea includes an upper platform 2 and a casing 1, a first through hole is opened on the upper platform 2, and also includes: a guide frame 3 arranged on the upper platform 2, the guide frame 3 is a quadrangular platform, and a trumpet 31 is arranged on the top of the guide frame 3; a lower platform 4 arranged below the upper platform 2, the upper platform 2 and the lower platform 4 are connected by a support column, and the lower platform 4 is opened with a second through hole; a plurality of positioning mechanisms 5 are arranged on the four sides of the first through hole and the second through hole, the positioning mechanism 5 includes a roller 51 and a shell 52, the roller 51 slides along the direction of the shell 52, and the roller 51 contacts the casing 1.

[0024] The top area of ​​the guide frame 3 is larger than the bottom area of ​​the guide frame 3. The main body of the guide frame 3 is welded by I-beams. Because the guide frame 3 is in the shape of a quadrangular pyramid as a whole and the edges are in the shape of diagonal braces, the bearing capacity is improved compared to the traditional vertical rods, and deformation can be effectively prevented. The bottom of the guide frame 3 is arranged on the side of the first through hole, and stiffening plates 32 are welded at the nodes where each I-beam is connected in the guide frame 3. The stiffening plates 32 further strengthen the connection strength of the guide frame 3 and reduce deformation during construction.

[0025] The opening area of ​​the top of the bell mouth 31 is larger than the opening area of ​​the bottom of the bell mouth 31. The bell mouth 31 is welded to the top of the guide frame 3. The bottom area of ​​the bell mouth 31 is slightly larger than the outer diameter of the casing 1, so that the casing 1 can pass through the bottom of the bell mouth 31 smoothly. When the casing 1 is inserted and hit, after the casing 1 is placed into the top of the bell mouth 31, the casing 1 can slide from the side wall of the bell mouth 31 to the bottom of the bell mouth 31. The bottom of the bell mouth 31 corresponds to the specific insertion position. Therefore, there is no need for workers to assist in positioning the casing 1 during the initial lowering, which reduces the positioning time and liberates the workers.

[0026] The area of ​​the first through hole is larger than that of the second through hole. An inclined ladder 6 is provided on the side of the inner wall of the first through hole. The bottom of the inclined ladder 6 is provided at the bottom of the lower platform 4. Workers can enter from the upper platform 2 to the lower platform 4 through the inclined ladder 6 and operate the positioning mechanism 5 on the lower platform 4.

[0027] The casing 1 is hoisted by the floating crane vessel and passes through the bell mouth 31, the first through hole and the second through hole, and then driven into the seabed.

[0028] The first through hole and the second through hole are both rectangular holes. A positioning mechanism 5 is installed on each side of the first through hole and the second through hole. The distance between the upper platform 2 and the lower platform 4 is three meters. The casing 1 is clamped by the two-layer positioning mechanism 5, and the casing 1 is fixed at two points, which avoids the disadvantage of the floating crane shaking, can resist the impact of sea water during high tide, and avoids the disadvantage of only being able to be lowered at low tide and slow water flow. The lowering work can also be carried out at high tide, thereby extending the working time.

[0029] like Figure 2 As shown, the positioning mechanism 5 also includes: a rack plate 53, a motor 54, two driving teeth 55, a small toggle tooth 56 and a large toggle tooth 57. The rack plate 53 is welded to the rear end of the roller 51. The rack plate 53 drives the roller 51 to move horizontally. The casing 1 is pushed by the horizontal movement of the roller 51. When the casing 1 is offset, the roller 51 moves horizontally to straighten the casing 1. A slideway 521 is provided on the inner wall of the shell 52. A slider 531 is provided on the side wall of the rack plate 53. The slider 531 is slidably connected to the slideway 521. A rack is provided on the top of the rack plate 53. The racks are distributed along the long side direction of the rack plate 53. The driving tooth 55 is meshed with the rack. The motor 54 drives one driving tooth 55. The large toggle tooth 57 drives another driving tooth 55. The small toggle tooth 56 is meshed with the large toggle tooth 57.

[0030] The output end of the motor 54 passes through the housing 52 and is fixedly connected to a driving tooth 55. After the motor 54 is started, it drives the driving tooth 55 to move the gear shaft plate to move.

[0031] Power outages often occur at construction sites. When a power outage occurs at the construction site, the large toggle tooth 57 is used to drive the other drive tooth 55 to rotate. A connecting shaft is provided at one end of the large toggle tooth 57, which passes through the shell 52 and is connected to the other drive tooth 55. The small toggle tooth 56 is rotatably connected to the side wall of the shell 52. The diameter and number of teeth of the small toggle tooth 56 are smaller than those of the large toggle tooth 57. By rotating the small toggle tooth 56 and then driving the large toggle tooth 57, effort can be saved and the burden on workers can be reduced.

[0032] The side walls of the small toggle tooth 56 and the large toggle tooth 57 are both welded with a pry piece 561, and there is a hole in the middle of the pry piece 561, and a pry bar can be inserted into the pry piece 561. When the roller 51 is manually driven, the worker rotates the pry bar to rotate the small toggle tooth 56. When the small toggle tooth 56 is damaged, the pry bar can also be inserted into the pry piece 561 of the large toggle tooth 57, thereby driving the tooth 55 shaft plate to move.

[0033] When the casing 1 is lowered, the casing 1 passes through the space surrounded by the rollers 51 , the rollers 51 are closely attached to the side walls of the casing 1 , and the rollers 51 rotate together with the movement of the casing 1 .

[0034] The side walls of the upper platform 2 and the lower platform 4 are both provided with fences 7, and the fences 7 are used to prevent someone from accidentally entering the construction site.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
