DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0028] Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of implementation of the present utility model. The change or adjustment of their relative relationship shall also be regarded as the scope of implementation of the present utility model without substantial change in technical content.

[0029] Referring to Figures 1-8 , a track link assembly for a ship-digging chassis assembly, includes a plurality of pairs of outer wing plates 1 and two straight plates 2 located between the plurality of pairs of outer wing plates 1. Two rollers 3 are arranged between the two straight plates 2. The outer wing plates 1, the straight plates 2 and the rollers 3 are connected by a pin shaft 4.

[0030] A mounting plate 5 is fixedly installed on the surface of one of the straight plates 2. A circular groove is formed on the upper surface of the mounting plate 5. A rotating ring 6 is rotatably installed in the circular groove. A plug rod 7 is vertically inserted into the rotating ring 6. A rotating ring 8 is fixedly sleeved on the plug rod 7. The plug rod 7 is locked with the rotating ring 6 through a locking component. A vertically opened oil inlet 9 with an L-shaped longitudinal section and communicating with the circular groove is formed on the upper surface of the mounting plate 5.

[0031] Multiple outer wing plates 1 close to the rotating ring 8 are connected to a track limit protection plate (not shown). After connection, the rotating ring 8 abuts against the track limit protection plate at this time, and the end of the pin shaft 4 does not contact the track limit protection plate. When the track link is moving, the rotating ring 8 will rollingly contact the track limit protection plate, which can reduce the wear of the pin shaft 4, improve the service life of the track link, and avoid problems such as breakage or detachment of the pin shaft 4, the outer wing plate 1 of the straight plate 2.

[0032] At the same time, the operator can also regularly introduce lubricating oil into the circular groove from the oil inlet 9 to lubricate the contact surface between the circular groove and the rotating ring 6, and avoid the accumulation of more dust at the gap between the circular groove and the rotating ring 6, so as to prevent the rotation of the plug rod 7 and the rotating ring 8 from jamming.

[0033] The locking assembly includes two locking blocks 10, a vertical rod 11 and two hinge rods 12. An installation groove is vertically formed on the upper surface of the insertion rod 7, and the vertical rod 11 is vertically slidably arranged in the installation groove. Two locking grooves 13 for inserting the two locking blocks 10 respectively are formed on the inner wall of the inner ring of the rotating ring 6. Slide openings are symmetrically formed on the wall of the installation groove, and the two locking blocks 10 are respectively slidably arranged in the two slide openings. Rectangular openings are symmetrically formed at the bottom end of the vertical rod 11. Two mounting blocks 14 are fixedly installed at one end of each locking block 10. Rotating shafts 15 are horizontally rotatably installed in the two mounting blocks 14 and the rectangular openings. The two ends of the two hinge rods 12 are respectively rotatably sleeved on multiple rotating shafts 15. Bar-shaped grooves are symmetrically and vertically formed on the wall of the installation groove. Mounting plates 16 are fixedly installed on the left and right side walls of the vertical rod 11. The two mounting plates 16 are respectively slidably arranged in the two bar-shaped grooves and are connected to the bar-shaped grooves through telescopic components. The telescopic components include telescopic springs 17 fixedly installed on the lower surface of the mounting plates 16, and the bottom ends of the telescopic springs 17 are fixedly connected to the bottom of the bar-shaped grooves.

[0034] When it is necessary to install the insertion rod 7 and the rotating ring 8, only need to control the upward movement of the vertical rod 11. At this time, the two locking blocks 10 will move closer to each other under the action of the two hinge rods 12. Until the mutually remote ends of the two locking blocks 10 respectively move back into the two slide openings, then insert the bottom of the insertion rod 7 into the rotating ring 6, and rotate the insertion rod 7. After the positions of the two locking blocks 10 correspond to the two locking grooves 13 respectively, release the vertical rod 11. The vertical rod 11 will quickly move downward under the elastic potential energy of the telescopic spring 17, and the two hinge rods 12 will also quickly rotate. The two locking blocks 10 will move away from each other at this time, and the mutually remote ends will respectively be inserted into the two locking grooves 13, thus completing the locking of the insertion rod 7 and the rotating ring 6. When it is necessary to disassemble the insertion rod 7 and replace the rotating ring 8, just pull the vertical rod 11 upward so that the end parts of the two locking blocks 10 are respectively removed from the two locking grooves 13, which is convenient and fast.

[0035] Limiting components are symmetrically arranged on the surface of the insertion rod 7. The limiting components are used to limit the upward movement of the vertical rod 11. The limiting components include L-shaped plates fixedly installed on the surface of the insertion rod 7, spring rods 18 fixedly installed on the surface of the L-shaped plates, and limiting blocks 19 fixedly installed at one end of the spring rods 18. Through openings are formed on the wall of the bar-shaped groove. One end of each of the two spring rods 18 respectively passes through the through openings. Oblique walls 20 are formed at the corners of the bottom of the mounting plate 16. The longitudinal section of the limiting block 19 is a right triangle, and the inclined surfaces of the two limiting blocks 19 are respectively arranged parallel to the two oblique walls 20.

[0036] When the vertical rod 11 rapidly moves downward under the elastic potential energy of the telescopic spring 17, the inclined walls 20 of the two mounting plates 16 will respectively slide into contact with the inclined surfaces of the two limiting blocks 19. Under the pressing action of the inclined surfaces and the inclined walls 20, the two limiting blocks 19 will move away from each other, and the two spring rods 18 will contract. Until the two mounting plates 16 move downward to no longer contact the limiting blocks 19, at this time, the two locking blocks 10 will respectively insert into the two locking grooves 13. And because the pressing force applied by the mounting plate 16 to the limiting block 19 disappears, the limiting block 19 will rapidly move back to its original position under the elastic potential energy of the spring rod 18. The two reset limiting blocks 19 will be respectively located above the two mounting plates 16, and their lower surfaces will respectively abut against the upper surfaces of the two mounting plates 16, so as to limit the upward movement of the vertical rod 11 and the two mounting plates 16, and assist in locking the insertion rod 7 and the rotating ring 8, avoiding the vertical rod 11 from moving up and down due to the influence of vibration force during the movement of the track link, resulting in the unlocking of the lock between the insertion rod 7 and the rotating ring 6.

[0037] When it is necessary to control the upward movement of the vertical rod 11, only need to control the two spring rods 18 to contract, so that the limiting block 19 no longer abuts against the upper part of the mounting plate 16, and then the restriction on the vertical rod 11 can be released.

[0038] In the present utility model, multiple outer wing plates 1 close to the rotating ring 8 are connected to the track limiting and protecting plate. After the connection, at this time, the rotating ring 8 abuts against the track limiting and protecting plate, and the end of the pin shaft 4 does not contact the track limiting and protecting plate. When the track link is moving, the rotating ring 8 will roll into contact with the track limiting and protecting plate, which can reduce the wear of the pin shaft 4, improve the service life of the track link, and avoid problems such as the fracture or detachment of the pin shaft 4, the straight plate 2, and the outer wing plate 1. At the same time, the operator can regularly introduce lubricating oil into the circular groove from the oil inlet 9 to lubricate the contact surface between the circular groove and the rotating ring 6, and avoid the accumulation of more dust at the gap between the circular groove and the rotating ring 6, resulting in the jamming of the rotation of the insertion rod 7 and the rotating ring 8.

[0039] In the present utility model, unless otherwise clearly defined and limited, the terms "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense.

[0040] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
