a turntable bearing 11, the turntable bearing 11 including an inner ring 111 and an outer ring 112 provided on an outer periphery of the inner ring 111, the outer ring 112 being rotatable relative to the inner ring 111;
the synchronous fluted disc 12, the synchronous fluted disc 12 is coaxially arranged on the periphery of the turntable bearing 11;
the anchor ear 13, anchor ear 13 is set up in the periphery of the synchromesh disc 12 coaxially, there are tooth grooves 1311 on the inner peripheral wall of anchor ear 13, the tooth groove 1311 is used for engaging with synchromesh tooth 121 on the synchromesh disc 12; the precision requirements of the anchor ear 13 and the synchronous teeth 121 of the synchronous fluted disc 12 are low, and the manufacturing cost is low.
The fixed upright post 20 is connected with the inner ring 111, and is integrally formed with the synchronous fluted disc 12;
the rotary upright post 30, the rotary upright post 30 and the fixed upright post 20 are coaxially arranged, and the rotary upright post 30 is connected with the outer ring 112 and integrally formed with the anchor ear 13.
The column rotation mechanism 10 is provided with a synchronous fluted disc 12 and a hoop 13, when self-locking is needed, the hoop 13 is controlled to be pressed on the synchronous fluted disc 12 under the action of external force, so that tooth grooves 1311 on the inner wall of the hoop 13 are meshed with synchronous teeth 121 of the synchronous fluted disc 12 to limit the hoop 13 to rotate relative to the synchronous fluted disc 12, and therefore the rotation of the rotation column 30 relative to the fixed column 20 is limited. When the rotary upright 30 is required to freely rotate relative to the fixed upright 20, the synchronous fluted disc 12 is separated from the anchor ear 13, the transmission efficiency of the inner ring 111 and the outer ring 112 is high, and the rotation speed is high. Secondly, on the premise of achieving the same transmission efficiency, the column swing mechanism 10 is small in size and low in mass compared with a worm gear mechanism.
In a specific embodiment, the hoop 13 includes a collar 131 and a locking member 132, two pairs of mounting lugs 1312 are formed at two ends of the collar 131, and the locking member 132 is disposed through a through hole on one pair of mounting lugs 1312 of the collar 131, and is used for pressing the collar 131 onto the synchronizing fluted disc 12, so that the synchronizing teeth 121 on the synchronizing fluted disc 12 are engaged with the tooth grooves 1311 on the inner wall of the hoop 13.
Specifically, the locking member 132 is rotated clockwise to drive the collar 131 to press against the synchromesh disc 12, that is, the tooth slot 1311 on the inner wall of the collar 131 is engaged with the synchromesh tooth 121 on the synchromesh disc 12, so as to limit the rotation of the rotation upright 30 relative to the fixed upright 20. Rotating locking member 132 counterclockwise separates anchor 13 from synchronizing toothed disc 12 and allows free rotation of rotating post 30 relative to stationary post 20.

When the locking member 132 is rotated clockwise, the two opposite mounting ears 1312 come closer together, compressing the resilient member 133. When the locking member 132 is rotated counterclockwise, the elastic member 133 is elastically deformed to spread the two opposite mounting lugs 1312, so that the synchronizing teeth 121 of the synchronizing fluted disc 12 are separated from the tooth grooves 1311 on the inner wall of the ferrule 131, and the operation is simple.
In a specific embodiment, locking member 132 includes a locking wheel 1322 and a driving rod 1321, wherein locking wheel 1322 is disposed at one end of driving rod 1321, and driving rod 1321 is disposed through a through hole formed in mounting ear 1312 of ferrule 131.

In a specific embodiment, the transmission rod 1321 is provided with a step portion 1323, where the step portion 1323 is located outside the mounting ear 1312, and is used to abut against one of the mounting ears 1312 to move toward the other mounting ear 1312.
When the hoop 13 and the synchronizing fluted disc 12 need to be locked, the locking fluted disc 1322 is rotated to drive the step portion 1323 to push one of the mounting lugs 1312 to move towards the other mounting lug 1312, so as to apply pressure to the hoop 131.
In a specific embodiment, the anchor 13 comprises a first body and a second body, the first body being detachably connected to the second body.
The detachable connection can improve the installation efficiency of the anchor ear 13 and reduce the installation difficulty.
In a particular embodiment, the other pair of mounting ears 1312 of ferrule 131 are secured by fasteners 135.
The fastening piece 135 is a bolt, and the nut and the two sides of the head of the bolt are clamped with the mounting lugs 1312 by screwing the nut of the bolt, so that the fixation is firm and reliable.
In other embodiments, stationary post 20 is coupled to inner race 111 and integrally formed with anchor ear 13, and the rotating post is coupled to outer race 112 and integrally formed with synchronizing toothed disc 12.
Or the fixed upright post 20 is connected with the outer ring 112 and integrally formed with the synchronous fluted disc 12, and the rotary upright post 30 is connected with the inner ring 111 and integrally formed with the anchor ear 13.
Or the fixed upright post 20 is fixedly connected with the outer ring 112, integrally formed with the anchor ear 13, and the rotary upright post 30 is connected with the inner ring 111, integrally formed with the synchronous fluted disc 12.
As an alternative to this embodiment, when self-locking is required, the hoop 13 is controlled to be pressed against the synchronizing fluted disc 12 under the action of external force, so that the tooth slot 1311 on the inner wall of the hoop 13 is meshed with the synchronizing tooth 121 of the synchronizing fluted disc 12, so as to limit the hoop 13 to rotate relative to the synchronizing fluted disc 12, and thus limit the rotation of the rotation upright 30 relative to the fixed upright 20. When the rotary upright 30 is required to freely rotate relative to the fixed upright 20, the synchronous fluted disc 12 is separated from the anchor ear 13, the transmission efficiency of the inner ring 111 and the outer ring 112 is high, and the rotation speed is high.
The working principle of the marine upright winch is as follows:
the marine scientific research equipment is positioned on the deck and is fixed at one end of the rope. When the ocean scientific research equipment needs to be distributed, the synchronous fluted disc 12 of the upright post rotary mechanism 10 is controlled to be separated from the anchor ear 13, namely the locking piece 132 is rotated anticlockwise, so that the tooth slot 1311 on the inner wall of the anchor ear 13 is separated from the synchronous tooth 121 of the synchronous fluted disc 12. The controller controls the driving device to work, and drives the rotary upright post 30 to rotate clockwise relative to the fixed upright post 20, so that the rope stretches out towards the sea water to drive the ocean scientific research equipment to descend.
When the marine scientific research equipment descends to the designated depth, the controller controls the driving device to stop working, and manually controls the upright post rotary mechanism 10 to perform self-locking, namely, the locking piece 132 is rotated clockwise to drive the hoop 13 to be tightly pressed on the synchronous fluted disc 12, so that tooth grooves 1311 on the inner wall of the hoop 13 are meshed with synchronous teeth 121 of the synchronous fluted disc 12 to limit the hoop 13 to rotate relative to the synchronous fluted disc 12, and further limit the rotary upright post 30 to rotate relative to the fixed upright post 20.
After the marine scientific research equipment finishes the data acquisition of the appointed depth, the controller controls the driving device to start working, and manually stops the separation of the synchronous fluted disc 12 and the anchor ear 13 of the upright post rotary mechanism 10, namely, the locking piece 132 is rotated anticlockwise, so that the tooth slot 1311 on the inner wall of the anchor ear 13 is separated from the synchronous tooth 121 of the synchronous fluted disc 12, the rotary upright post 30 rotates clockwise relative to the fixed upright post 20 to drive the rope to extend continuously, and the marine scientific research equipment is driven to descend continuously until the marine scientific research equipment is laid on the sea bottom.
When the marine scientific research equipment needs to be recovered, the controller controls the driving device to start working, and manually stops the separation of the synchronous fluted disc 12 and the hoop 13 of the upright post rotary mechanism 10, and the rotary upright post 30 rotates anticlockwise relative to the fixed upright post 20 so as to recover the marine scientific research equipment to the deck.
The column rotation mechanism 10 is provided with a synchronous fluted disc 12 and a hoop 13, when self-locking is needed, the hoop 13 is controlled to be pressed on the synchronous fluted disc 12 under the action of external force, so that tooth grooves 1311 on the inner wall of the hoop 13 are meshed with synchronous teeth 121 of the synchronous fluted disc 12 to limit the hoop 13 to rotate relative to the synchronous fluted disc 12, and therefore the rotation of the rotation column 30 relative to the fixed column 20 is limited. When the rotary upright 30 is required to freely rotate relative to the fixed upright 20, the synchronous fluted disc 12 is separated from the anchor ear 13, the transmission efficiency of the inner ring 111 and the outer ring 112 is high, and the rotary speed is high. Secondly, on the premise of achieving the same transmission efficiency, compared with a worm gear, the upright post rotary mechanism 10 has small volume and low mass. The marine upright winch is provided with the upright slewing mechanism 10, so that the requirements of arranging marine scientific research equipment on the sea bottom and staying at different depths to collect data can be met.
Example two
Referring to fig. 1 to 4, the present embodiment is substantially the same as the above embodiment, except that: the collar 131 is provided with a limiting hole 1313, and a locking pin 14 is arranged at the limiting hole 1313. Wherein, the locking pin 14 can enter or extend out of the limit hole 1313, and the pin shaft of the locking pin 14 has a self-locking position.
Specifically, when the fixed upright 20 and the rotary upright 30 need to be automatically locked, the pin shaft of the locking pin 14 is pulled out and screwed into the self-locking position, then the locking wheel disc 1322 is manually loosened in the anticlockwise direction, the hoop 13 is spread by the elastic piece 133, the hoop 13 is separated from the synchronous fluted disc 12, and the rotary upright 30 can rotate relative to the fixed upright 20. When the locking pin 14 is rotated to be positioned at the limiting hole 1313, the pin shaft of the locking pin 14 can be immediately inserted into the limiting hole 1313, so that the automatic locking of the hoop 13 and the synchronous fluted disc 12 is realized. When automatic locking is not needed, the pin shaft of the locking pin 14 is pulled out, the self-locking position is not screwed in, and the rotary upright 30 can freely rotate relative to the fixed upright 20.
By screwing the pin shaft of the locking pin 14 into the self-locking position in advance, the synchronous teeth 121 of the synchronous fluted disc 12 are meshed with the tooth grooves 1311 on the inner wall of the ferrule 131, so that the rotary upright post 30 and the fixed upright post 20 are automatically locked, and the situation that an operator forgets to rotate the locking fluted disc 1322 to run away is prevented, and the safety is high.
In a specific embodiment, there are two limiting holes 1313, and two limiting holes 1313 are respectively provided at opposite ends of the ferrule 131.
Through the cooperation of the two limiting holes 1313 and the two locking pins 14, the clamping sleeve 131 is uniformly stressed, and is firm and reliable.
