Abstract
Description
Technical Field
[0001] The utility model relates to a clamping device for a target object of a marine lifting platform, which can clamp and fix an underwater columnar target object to facilitate subsequent recovery. Background Art
[0002] The surface area of the earth is 5.1×10 8 km 2 Among them, the ocean area is 3.6×10 8 km 2 accounting for about 71% of the total surface area of the earth. With the rapid consumption of land resources, human beings have locked the development goal to the ocean. With the continuous increase of labor costs for underwater construction and underwater operations, people often need to clamp and fix some columnar objects in underwater construction to facilitate subsequent recovery work. Most of the existing clamping and fixing work for underwater columnar objects needs to be completed manually, which not only seriously wastes manpower and material resources, but also has a high cost. In addition, when operating under some bad weather conditions, there are also great potential safety hazards. Therefore, solving the problem of clamping and fixing underwater columnar objects to facilitate subsequent recovery has become a new problem that troubles people. Content of the Utility Model
[0003] Based on the above, the utility model provides a clamping device for a target object of a marine lifting platform. This clamping device can not only safely and reliably clamp and fix an underwater columnar target object, but also be modularly disassembled to reduce the space occupied by the clamping device.
[0004] In order to achieve the above object, a clamping device for a target object of a marine lifting platform includes:
[0005] A clamping device for a target object of a marine lifting platform, characterized in that it includes a motor (2), a lifting frame (3), a lifting platform (5) and a clamping arm mechanism (10). The lifting platform (5) is lowered and lifted by an axle (8), wheels (9) and a motor (2); the lifting platform (5) is installed in the channel steel of the lifting frame (3), and a number of rolling wheels (7) are installed thereon;; the clamping arm mechanism (10) pushes a clamping plate (11) through a hydraulic cylinder (12) to clamp and fix a columnar object; the lifting frame (3) is composed of a number of channel steels and is installed on the stern (1) surface in an inverted L shape. Through the rolling wheels (7), the columnar target object (16) is dragged from the lifting platform (5) to the stern surface of the lifting frame (3) to complete the recovery of the underwater columnar target object (16).
[0006] Preferably, the connection parts of the lifting frame (3) are connected by coupling bolts (4). When the operation is completed, the fit at the coupling bolts (4) can be disconnected, and the lifting platform (5) can be taken out to reduce the space occupied by the entire device.
[0007] Preferably, the lifting platform (5) is installed inside the channel steel of the lifting frame (3) and consists of a lifting seat (6), rolling wheels (7), axles (8), wheels (9) and support seats (15). The ropes are fixed to both ends of the axle (8) by two motors (2) on the deck surface, and the forward and reverse rotations of the motors (2) are used to lower and lift the lifting platform (5).
[0008] Preferably, the clamping arm mechanism (10) consists of a hydraulic cylinder (12), a clamping plate (11) and a baffle (13). The linear motion of the hydraulic cylinder (12) is converted into the circular motion of the clamping plate (11). During the rotation of the clamping plate (11), the columnar object (16) will be abutted against the baffle (13), thereby clamping the columnar object (16).
[0009] Preferably, the clamping plate (11) of the clamping arm mechanism (10) is semi-circular, which can not only adjust the posture of the columnar object (16) to be parallel to the stern (1) to avoid collision with the stern (1), but also clamp and fix it.
[0010] Preferably, the baffle (13) of the clamping arm mechanism (10) is made of channel steel, which has a waist-shaped hole and is equipped with a first limit bolt (14) and a second limit bolt (17). When the lifting platform (5) is lifted to be flush with the lifting frame (3), the baffle (13) is pushed backward. At this time, the first limit bolt (14) is the rotation point of the baffle (13), and the second limit bolt (17) moves along the waist-shaped hole, so that the baffle (13) slides down into the lifting platform (5) to prevent interference during the process of dragging the columnar object (16) from the lifting platform (5) to the stern surface of the lifting frame (3).

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0016] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0017] In the description of the present invention, it should also be noted that unless otherwise clearly defined and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0018] Next, the present invention will be further described with reference to the accompanying drawings and specific embodiments.
[0019] As Figure 1 shown, a lifting device for recovering underwater columnar objects mainly includes a motor 2, a lifting frame 3, a lifting platform 5, and a clamping arm mechanism 10.
[0020] As Figure 1 shown, the lifting frame 3 is composed of several channel steels and is installed on the surface of the stern 1 in an inverted L shape. Several rolling wheels 7 are installed at the upper end to drag the underwater columnar object 16 from the lifting platform 5 to the surface of the stern of the lifting frame 3, completing the recovery of the underwater columnar object 16.
[0021] As Figure 3As shown in the figure, the clamping arm mechanism 10 is composed of a hydraulic cylinder 12, a clamping plate 11 and a baffle 13. The baffle 13 is made of channel steel, which has an oblong hole, and the first limit bolt 14 and the second limit bolt 17 are installed on it. When the lifting platform 5 is lifted to be flush with the lifting frame 3, the baffle 13 is pushed backward. At this time, the first limit bolt 14 is the rotation point of the baffle 13, so that the second limit bolt 17 moves along the oblong hole, so that the baffle 13 slides down into the lifting platform 5 to prevent interference during the process of dragging the columnar object 16 from the lifting platform 5 to the stern surface of the lifting frame 3.
[0022] As Figure 2 shown in the figure, the clamping plate 11 is semi-circular. The linear motion of the hydraulic cylinder 12 is converted into the circular motion of the clamping plate 11, so that the attitude of the columnar object 16 can be adjusted to be parallel to the stern 1, avoiding collision between the underwater columnar object 16 and the stern 1, and it can also be clamped and fixed.
[0023] As Figure 1 shown in the figure, the connection part of the lifting frame 3 is connected by a coupling bolt 4. When the operation is completed, the cooperation at the coupling bolt 4 can be disconnected, and the lifting platform 5 can be taken out to reduce the space volume occupied by the entire clamping device.
