The following description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention.

In an embodiment, as shown in fig. 1 to 5, the present invention discloses a mechanical rope length measuring device 100, which is applied to an anchor machine on a ship to identify a rope length of a hawser. The anchor machine comprises a frame 200, a chain wheel assembly 300 rotatably connected to the frame 200, and a chain rope wound on the chain wheel assembly 300. The anchor sprocket assembly 300 rotates to pay out and pay out the chain line so that the chain line is at the appropriate length.

The mechanical rope length measuring device 100 comprises a driving wheel 50 connected to a chain wheel assembly 300, a scale frame 10 fixed on a frame 200, a transmission shaft 30 rotatably connected to the scale frame 10, a transmission wheel 40 fixed on the transmission shaft 30 and a pointer assembly 20 spirally connected to the transmission shaft 30, wherein the transmission wheel 40 is in transmission connection with the driving wheel 50. The anchor sprocket assembly 300 is rotated back and forth and rotates the driving wheel 50, i.e., the driving wheel 50 rotates in synchronization with the anchor sprocket assembly 300, so that the driving wheel 50 can transmit the change in the length of the chain rope caused by the rotation of the anchor sprocket assembly 300 to the driving pulley 40.

Alternatively, the transmission wheel 40 is in driving connection with the driving wheel 50, and the two can be in proportional driving. For example, the transmission wheel 40 is connected with the driving wheel 50 through a belt or a chain to form a belt pulley set or a chain pulley set for driving, and the transmission range is wide. Alternatively, the drive wheel 40 is driven in frictional contact with the drive wheel 50. Optionally, the transmission wheel 40 is in gear engagement with the driving wheel 50, so that the two form a high-precision matching structure. Of course, an intermediate gear can be arranged between the transmission wheel 40 and the driving wheel 50 to form multi-stage gear transmission, so that the transmission ratio range is enlarged. In an alternative embodiment, the transmission ratio of the drive wheel 50 and the transmission wheel 40 is set to i, wherein i is greater than or equal to 0.5 and less than or equal to 5. For example, the transmission ratio is configured to be 0.5, 06, 0.7, 0.8, 0.9, 1, 2, 3, 4, 5, etc., so as to adjust the transmission ratio of the two, and then correspondingly convert into the rope length change.

The scale frame 10 is provided with scale values 61, and the hand assembly 20 moves and points to one of the scale values 61 as the driving shaft 30 rotates. The indicating needle assembly 20 is linearly and reciprocally moved along the scale frame 10 in accordance with the forward or reverse rotation of the driving shaft 30, wherein the indicating needle assembly 20 points to a scale 61 calibrated on the scale frame 10, the scale 61 corresponding to the length of the chain rope located outside the anchor sprocket assembly 300. The user can know the length of the rope by reading the numerical value corresponding to the scale value 61, and the rope is intuitive and clear.

The frame body 11 is provided with a sliding groove parallel to the transmission shaft 30, the pointer assembly 20 is spirally connected to the transmission shaft 30 and penetrates out along the sliding groove, and the end of the pointer assembly 20 faces the scale 61. Part of the pointer assembly 20 is located in the frame body 11, optionally, the pointer assembly 20 slides on the scale frame 10 and partially penetrates out of the sliding groove, and the pointer assembly 20 is matched with the groove wall of the sliding groove and is attached to the scale frame 10, so that the sliding direction of the pointer assembly 20 is stable and controllable. In an embodiment, the sliding groove is disposed at the lowest position of the frame 11 in the gravity direction, and the liquid can flow out from the sliding groove, so as to prevent the liquid such as seawater from sea waves impacting the ship from being retained in the frame 11. That is, when the mechanical rope length measuring device 100 is in an operating state, the slide groove faces downward.

As shown in fig. 3 to 5, the pointer assembly 20 may alternatively include a nut holder 21 screw-coupled to the driving shaft 30 and an orientation pointer 22 fixed to the nut holder 21, the nut holder 21 being slidably coupled to the frame body 11, the orientation pointer 22 being bent to protrude from the nut holder 21 and having a distal end pointing to the scale 61. Nut seat 21 is threadedly coupled to drive shaft 30, and the pitch of the threads of drive shaft 30 is adjusted according to the length of the chain rope wound around anchor sprocket assembly 300. The nut seat 21 is slidably fitted with the slide groove to be restricted from rotating with respect to each other, preventing the nut seat 21 from rotating. The directional pointer 22 is bent and protruded from the nut seat 21 and points to the scale 61, and the setting position of the scale 61 is flexible and convenient. Optionally, the scale frame 10 further comprises at least one guide post 31 parallel to the drive shaft 30, and the nut holder 21 is slidably connected to the guide post 31 and slides along the guide post 31 under the driving of the drive shaft 30.

The graduated scale 60 is in a plate shape, and the scale 61 faces the operation direction of a user, so that the user can observe the graduated scale conveniently.

Further, the scale frame 10 further includes an adjusting bracket 70 mounted to the frame body 11, and the adjusting bracket 70 is detachably connected to the frame 200. The adjusting bracket 70 is used to connect the frame body 11 and the frame 200, thereby changing the relative positions of the two. The adjusting bracket 70 may be configured as a support arm structure, such as a linear column, a curved bending arm structure, etc., to avoid interference in space and adjust the position of the driving wheel 40.
