Detailed Description
The invention is further described below in connection with the accompanying drawings, which are provided solely for illustration of specific embodiments of the invention and are not to be construed as limiting the invention in any way, as follows:
As shown in fig. 1 and referring to fig. 2, a cable baling press for a ship includes a baling press body 11, a grip portion 2, and a fixed guide portion 14, which are integrally formed. The fixed guide 14 comprises a guide slot 13 arranged at the side end of the baler body 1, the guide slot 13 being adapted to the thickness of the steel tie used for baling, so that the steel tie used for baling can just pass through the guide slot 13 unhindered. The baler body 11 comprises a cylindrical cavity. The torsion shaft 16 is rotatably disposed in a cylindrical cavity of the baler body 11 and includes first and second torsion shafts 1601, 1602 that are axially centered on collinearly. The rotary groove 7 is provided at one end of the second twist shaft 1602, is the same as the guide groove 13 in groove depth and groove width, and is located on the same side of the baler body 11 as the guide groove 13. The other end of the second torsion shaft 1602 has a threaded bore. One end of the first torsion shaft 1601 is provided with a stud corresponding to the threaded hole of the second torsion shaft 1602, and the first torsion shaft 1601 and the second torsion shaft 1602 are connected through the stud and the threaded hole. The fifth wheel 8 is a "windmill type" toothed ratchet structure and is fixed to the second torsion shaft 1602. The sounding wheel 10 has an outer diameter which corresponds to and is disposed in a cylindrical cavity of the baler body 11. The sounding wheel 10 has a cylindrical receiving chamber inside. The fifth wheel 8 has an outer diameter that corresponds to and is positioned in the receiving cavity of the sounding wheel 10. The fifth wheel 8 is capable of unidirectional rotation with respect to the sounding wheel 10. The sounding wheel 10 is preferably made of hard metal, and is circumferentially provided with a plurality of sounding grooves 101. The grip portion 2 has an adjustment cavity inside which communicates radially with the cylindrical cavity of the baler body 11. The clamping element 5 is preferably made of hard metal or ceramic, and the maximum outer diameter is adapted to the adjusting cavity of the holding part 2 and is placed in the adjusting cavity, so that the clamping element 5 can slide in the adjusting cavity. The elastic piece 4 and the torsion adjusting piece 3 are arranged in the adjusting cavity of the holding part 2, one end of the clamping piece 5 is elastically connected with the torsion adjusting piece 3 through the elastic piece 4, and the other end is clamped in the sounding groove 101. When the sounding wheel 10 rotates, the clamping piece 5 can enter the adjacent sounding groove 101 from one sounding groove 101, and meanwhile, can strike the sounding groove 101 to make a sound under the elastic action of the elastic piece 4. The torque force adjusting piece 3 is in threaded connection with the holding part 2, the far end of the torque force adjusting piece 3 connected with the elastic piece 4 is fixedly connected with the knob 1, and the distance between the connecting end of the torque force adjusting piece 3 and the elastic piece 4 and the clamping piece 5 is changed by rotating the knob 1, so that the rotating torque of the sounding wheel 10 is controlled.
The shear shaft 12 is rotatably fixed to the baler body 1. One axial end of the shearing shaft 12 is provided with a shearing groove with a straight-line-shaped opening, and the other axial end is fixedly connected with the shearing rod 15. The groove depth and the groove width of the shearing groove are the same as those of the guide groove 13, and the shearing groove can be overlapped with the guide groove 13 on the rotation path of the shearing shaft 12, so that the steel tie can pass through the shearing groove and the guide groove simultaneously. By the rotation of the shear shaft 12, a shearing force can be generated at a position where the shearing groove contacts the guide groove 13, and the steel tie is sheared.
In some embodiments, the marine cable packer further comprises a torque mark 18 arranged on the outer side of the holding part 2, and the torque mark 18 can read a preset torque of the marine cable packer, so that torque adjustment is facilitated.
As shown in fig. 3 and referring to fig. 1, the inner cavity wall of the accommodating cavity of the sounding wheel 10 comprises a plurality of limiting grooves 101, and the size of the connecting part of the limiting grooves 101 and the opening of the inner cavity wall of the accommodating cavity is smaller than that of the limiting grooves 101. The spacing body includes gag lever post 63 and sets up in the spacing head 62 of its tip, and spacing groove 101 size suits with the size of spacing head 62, and spacing groove 101 suits with the opening junction size that holds the chamber inner chamber wall and gag lever post 63 size for the spacing body can slide in spacing groove 101 and can not break away from with spacing groove 101. The limiting spring 61 is arranged between the limiting groove 101 and the limiting head 62, so that the limiting rod 63 protrudes out of the inner cavity wall of the accommodating cavity of the sounding wheel 10. The length of the limiting body is smaller than the depth of the limiting groove 101, so that the limiting body can completely enter the limiting groove 101 when the limiting body is subjected to external force. The fifth wheel 8 is pressed into the limit groove 101 by means of the windmill-shaped tooth-shaped ratchet structure when rotating clockwise, and the fifth wheel 8 can rotate synchronously with the sounding wheel 10 due to the limit effect of the limit body when rotating anticlockwise.
As shown in fig. 4 and referring to fig. 2, in some embodiments, a locking ratchet 19 is fixed to the first twist axle 1601. The pawl 20 is provided on the lock lever 17 rotatably connected to the first torsion shaft 1601, and the lock lever 17 swings, so that the fifth wheel 8 can rotate in the same direction as the lock ratchet 19, and the convenience of rotation of the torsion shaft 16 can be improved.
The working principle of the invention is that under the driving rotation of the locking rod 17, the first torsion shaft 1601 is fastened with the second torsion shaft 1602, the rotary groove 7 synchronously rotates along with the torsion shaft 16, and the steel ribbon inserted in the rotary groove 7 is wound and tensioned under the rotation effect for fixing the cable. At this time, the fifth wheel 8 rotates clockwise with the torsion shaft 16, the connection limiting piece 6 is pressed by the windmill-shaped tooth-shaped ratchet structure, the limiting rod 63 enters the limiting groove 101, and the sounding wheel 10 rotates relatively to the fifth wheel 8. After the rated torque is reached, under the reaction force of the steel ribbon, the connecting wheel 8 fixed on the second torsion shaft 1602 reversely rotates, and due to the limiting function of the connecting limiting piece 6, the first torsion shaft 1601 and the second torsion shaft 1602 are unscrewed simultaneously, so that the sounding wheel 10 and the connecting wheel 8 synchronously rotate, further the clamping piece 5 enters the adjacent sounding grooves 9 from the original sounding grooves 9 in the circumferential direction of the sounding wheel 10, and the clamping piece and the sounding wheel 10 emit knocking sounds under the elastic function of the elastic piece 4 so as to remind an operator of reaching the rated torque. At this time, the cable can be fixed by the steel ribbon with constant moment by using the tool to lock the binding buckle.
The components of the marine cable packer are closely connected to form a complete whole, so that the steel ribbon is stopped from being tensioned and rattled after the rated moment is achieved, the problem of too loose or too tight cables caused by manual operation is effectively prevented, the components together form the technical scheme of the cable packer, the cable packer cannot be independently split, and the corresponding technical problems created by the cable packer cannot be solved by overlapping independent components with similar functions.
By now it should be appreciated by those skilled in the art that while exemplary embodiments of the invention have been shown and described in detail herein, many other variations or modifications that are consistent with the principles of the invention may be directly determined or derived from the disclosure without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
