Description

Technical Field

[0001] The utility model relates to the technical field of tiller and rudder stock matching, in particular to a tiller anti-loosening and pressing device with a key. Background Art

[0002] The rudder system usually refers to the general term for the entire rudder control system, which includes the rudder stock, tiller, rudder blade, steering device (such as steering gear, steering wheel) and the mechanical structure connecting these components. The rudder stock is the component on the ship that connects the rudder blade and the steering device. It is used to transmit the driver's steering command to the rudder blade to change the direction of the ship. The tiller is the component used by the driver to directly operate the steering gear. At present, the tiller and the rudder stock are connected by a key to transmit torque. The key is put into the keyway of the rudder stock and hammered in and tightened with a hammer. During the operation of the ship, there is no reliable preventive measure for the loosening of the key due to the vibration of the rudder system. When the key is loose, the rudder stock and the rudder stock will be displaced, resulting in inconsistency between the rudder angle command and the actual rudder angle, which brings potential hidden dangers to navigation safety.

[0031] In one embodiment of the present invention, referring to Figure 1 As shown, in order to further limit the locking piece 4 and facilitate flexible adjustment of the height of the locking piece 4, it also includes a second nut 7 threadedly connected to the full-thread screw, the second nut 7 abuts the locking piece 4 and the second nut 7 is located on the side of the locking piece 4 relative to the first nut 6, that is, the second nut 7 is located at the bottom of the locking piece 4, the first nut 6 and the second nut 7 press the locking piece 4 from the upper and lower sides respectively, and the full-thread screw enables the first nut 6 and the second nut 7 to be adjusted to any height, so that the locking piece 4 can press the connecting piece 5 with different installation depths.

[0032] In one embodiment of the present invention, referring to Figure 1 As shown, the locking member 4 is configured as a thin plate structure, the locking member 4 is vertically disposed to the axis of the full-thread screw, and the bottom of the locking member 4 fully abuts against the end 51 of the connecting member 5 .

[0033] In one embodiment of the present invention, referring to Figure 2 As shown, in order to limit one end of the locking member 4 in the second direction Y through the positioning member 3 , a first through hole 41 is provided at one end of the locking member 4 , and the full-thread screw passes through the first through hole 41 .

[0034] In one embodiment of the present invention, referring to Figure 2 As shown, in order to limit the other end of the locking member 4 in the first direction X and the second direction Y by the bolt 8, the other end of the locking member 4 is provided with a second through hole 42, and the bolt 8 passes through the second through hole 42 and is threadedly connected to the connecting member 5.

[0035] In one embodiment of the present invention, referring to Figure 1 As shown, the locking member 4 abuts against the end 51 of the connecting member 5, and the end 51 is larger than other parts of the connecting member 5, which is convenient for hitting the connecting member 5 with a hammer; and the abutment between the end 51 and the locking member 4 is fixedly connected by the bolt 8.

[0036] In one embodiment of the present invention, referring to Figure 1 As shown, the rudder stock 1 is provided with a keyway, and the keyway extends along the first direction X of the rudder stock 1.

[0037] In one embodiment of the present invention, referring to Figure 2 As shown, both ends of the locking member 4 are arranged as semicircular structures to prevent the edges of the locking member 4 from scratching the workers' hands.

[0038] The working principle of the keyed tiller anti-loosening and clamping device of the utility model is:

[0039] With the help of a hammer or a jack or other tool, the connecting piece 5 is knocked or pushed into the key slots of the tiller handle 2 and the tiller stock 1 to achieve a key connection between the tiller handle 2, the tiller stock 1 and the connecting piece 5. Then, the first through hole 41 of the locking piece 4 is passed through the positioning piece 3 and the height of the locking piece 4 is adjusted until one end of the locking piece 4 abuts against the end 51 of the connecting piece 5 along the first direction X. The connecting piece 5 and the locking piece 4 are locked by the bolt 8. At the other end of the locking piece 4, the heights of the first nut 6 and the second nut 7 are adjusted to match the height of the locking piece 4 and the locking piece 4 is pressed to complete the positioning of the locking piece 4. The locking piece 4 presses the end 51 of the connecting piece 5 along the first direction X to prevent the connecting piece 5 from loosening in the reverse direction.
