Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1 to 6, the light spring type ocean mud mining grab bucket of the present embodiment mainly includes a bracket 1, a grab bucket assembly 2, a release mechanism 3, a lifting and closing mechanism 4, and a spring 5.
The support 1 is a double-layer structure and mainly comprises a top plate 11 at the upper part and a base 13 at the lower part. The base 13 is welded by channel steel made of 316 materials, in order to ensure that the center of gravity moves downwards, the counter weights 14 are arranged on two opposite corners of the base 13, the base 13 is ensured to be parallel to the sea bottom surface and land when being released, and the other two opposite corners of the base 13 are respectively welded with a connecting rod hole 52. Four corners of the top plate 11 are fixedly connected with the base through a connecting plate 13 respectively, and meanwhile, one pair of opposite side surfaces of the top plate 11 are connected with the base 13 through connecting rods, so that the support 1 is firmer.
The center of the top plate 11 is provided with a central hole 19, the center of the bottom surface of the top plate 11 is provided with a hollow sleeve 18 which is vertically downward, and the sleeve 18 and the central hole 19 form a channel for the steel wire rope 41 to pass through. The bottom surface of the top plate 11 is also provided with two guide posts 16 respectively, and the two guide posts 16 are symmetrically arranged at two sides of the sleeve 18 and used for installing the spring 5. The other pair of opposite sides of the top plate 11 are each provided with an arm slot 17. the arm slots 17 may be formed by two parallel spaced plates, the projecting ends of which may be closed, but are not closed in this embodiment.
The grab bucket assembly 2 is detachably mounted on the support 1, and fig. 1 and 2 are schematic views of the grab bucket assembly 2 not being detached from the support 1, at this time, the grab bucket assembly 2 is fixed on the support 1 through the release mechanism 3, and the grab bucket assembly 2 is in an unreleased state.
The grab bucket assembly 2 comprises an inverted U-shaped mounting plate 21 and a grab bucket 22 which is fixed at the bottom of the mounting plate 21 and can be opened and closed. The mounting plate 21 is located below the top plate 11 and the grab 22 can pass out of the middle of the base 13. The grab bucket 22 mainly comprises two bucket-shaped jaws hinged to each other, and the concrete structure is conventional. Two extension arms 23 are provided on the back of the grab 22, one on each bucket jaw. The mounting plate 21 is provided with a through hole for the guide post 16 to pass through, and the spring 5 is sleeved on the guide post 16 between the top plate 11 and the mounting plate 21. In the case of the illustrated grapple assembly 2 connected to the frame 1, the extension arm 23 is directed vertically upwards and the top part is snapped into the arm slot 17 and then positioned by the latch 24, and the grapple 22 is held open, with the spring 5 compressed, since the extension arm 23 cannot be opened to both sides. Thus, once the releasing mechanism 3 is actuated to separate the grab bucket assembly 2 from the bracket 1, the spring 5 releases the stored force, the grab bucket 22 will fall vertically in an open form and be inserted into a mud layer, and at the moment, the extension arm 23 is just pulled out of the arm groove 17, so that the subsequent lifting and closing are facilitated.
The release mechanism 3 is used for controlling the connection relationship between the grab bucket assembly 2 and the bracket 1 and mainly comprises a contact bottom plate 31, a brake sleeve 32, a connecting rod 33, a sliding ring 34, a cam 35 and a hook groove 36. Wherein, the connecting rod 33 is in an inverted U shape, and the two bottom ends are respectively connected with the bottom contact sheet 31 after passing through the connecting rod hole 15 of the base 13. The two brake sleeves 32 are fixed on the connecting rod 33 above the connecting rod hole 15, and the diameter of each brake sleeve 32 needs to be larger than that of the connecting rod hole 15. The bottom plate 31 and the braking sleeve 32 are respectively positioned to form an upper stop position and a lower stop position of the connecting rod 33. The slip ring 34 is located at the center of the top surface of the connecting rod 33 and is through, and the slip ring 34 is sleeved on the sleeve 18 in a vertically sliding manner. Through the two connecting rod holes 15 and the sleeve 18, the directional movement of the connecting rod 33 can be realized, and unstable conditions such as deflection and swing can not occur. The cam 35 and the hooking groove 36 are two and are symmetrically arranged on both sides of the sleeve 18. The hook groove 36 may be formed by a rectangular groove dug in the middle of a vertical plate. The cam 35 is C-shaped, both ends of the cam are arc-shaped, and the center of the cam is rotatably connected below the top plate 11. The center of rotation of the cam 35 is provided with an elastic member (not shown) such as a torsion spring, so that the lower end of the cam 35 is opened outward to be disengaged from the hook groove 36 when the cam 35 is not applied with force. The slip ring 34 is located between the two cams 35, and in the illustrated case of the grapple assembly 2 being connected to the frame 1, the link 33 is in the lower stop position, the slip ring 34 abuts against the upper end of the cams 35, so that the lower end of the cams 35 are snapped into the hook grooves 36, and the grapple assembly 2 is connected to the frame 1. When the mud grab is thrown to the seabed, the bottom contact plate 31 firstly contacts with the seabed to drive the connecting rod 33 to move upwards, so that the sliding ring 34 moves upwards to be separated from the cam 35, and the lower end of the cam 35 is separated from the hook groove 36 under the driving of the rotation center elastic piece, so that the connection between the grab bucket assembly 2 and the bracket 1 is released.
The lifting closing mechanism 4 is used for recovering the whole device after mud mining is finished, and mainly comprises a steel wire rope 41, a first pulley 42 and a second pulley 43. The number of the first pulleys 42 and the number of the second pulleys 43 are two, the first pulleys 42 are respectively rotatably connected to two opposite corners of the base 13, the second pulleys 43 are symmetrically rotatably connected to the top surface of the mounting plate 21, and the specific fixing mode is the prior art. One end of the steel wire rope 41 is connected to the top of one of the extension arms 23 through a hook, and the other end of the steel wire rope passes through the central hole 19 upwards after passing around the first pulley 42 and the second pulley 43 on the side, is folded to form a lifting ring, passes through the central hole 19 downwards, passes around the second pulley 43 and the first pulley 42 on the other side, and is connected with the top of the other extension arm 21. After the grab bucket 22 is inserted into a mud layer, the top of the extension arm 23 is separated from the arm groove 17, so that the top of the extension arm 23 can be pulled outwards only by lifting the steel wire rope 41 upwards, the grab bucket 22 is closed, and the pulley I42 is fixed on the base 13, so that the steel wire rope 41 is lifted upwards, and the whole mud-mining grab bucket can be recovered. In addition, in order to ensure the sealing performance of the closed grab 22, a protruding groove 25 may be welded at the joint of the grab.
To sum up, the utility model discloses a mud grab bucket is adopted in light-duty spring ocean, structural design is exquisite, and the quality is light, and it is big to adopt the mud impact force, can realize adopting mud deeply in the whole sea, and operation safety and stability has fine spreading value.
The above detailed description is specific to possible embodiments of the present invention, and the embodiments are not intended to limit the scope of the present invention, and all equivalent implementations or modifications that do not depart from the scope of the present invention should be included within the scope of the present invention.
