[0024] Specific embodiments are given below.
[0025] Please refer to Figure 1 - Figure 4, the utility model provides a lug reinforcement structure. Fixed plates 101 are fixedly connected to both sides of the lug body 1; a reinforcement rod 102 is fixedly connected to the bottom of the fixed plate 101; a connecting plate 103 is fixedly connected to the bottom of the fixed plate 101; a screw rod 104 is rotatably connected to the surface of the connecting plate 103; a rotating disk 105 is fixedly connected to one end of the screw rod 104; a grip 112 is fixedly connected to one side of the rotating disk 105; a moving block 106 is threadedly connected to the surface of the screw rod 104; first connecting rods 107 are fixedly connected to both sides of the moving block 106; a second connecting rod 108 is fixedly connected to the top of the first connecting rod 107; a sliding block 109 is fixedly connected to one end of the second connecting rod 108; a reinforcement plate 110 is fixedly connected to the top of the sliding block 109; a sliding groove 111 adapted to the sliding block 109 is provided at the top of the fixed plate 101. During operation, when the object is heavy, the rotating disk 105 on the screw rod 104 is rotated through the grip 112. The rotating disk 105 drives the screw rod 104 to rotate, the screw rod 104 drives the moving block 106 to move, the moving block 106 drives the first connecting rod 107 to move, the first connecting rod 107 drives the second connecting rod 108 to move, the second connecting rod 108 drives the sliding block 109 to slide in the sliding groove 111, and then the sliding block 109 drives the reinforcement plate 110 to move, so that the reinforcement plate 110 contacts and fits with the lug body 1. By passing the hoisting rope through the reinforcement plate 110 and the lug body 1, the contact area between the lug and the rope is increased, thereby reinforcing the lug and reducing damage to the lug.
[0026] Further, as Figure 3 shown, a connecting block 2 is fixedly connected to the bottom of the connecting plate 103; a limiting slider 201 is fixedly connected to the bottom of the moving block 106; a limiting slide bar 202 is slidably connected inside the limiting slider 201; both ends of the limiting slide bar 202 penetrate through the limiting slider 201 and are connected to the connecting block 2 and the lug body 1. During operation, the moving block 106 drives the limiting slider 201 to slide on the limiting slide bar 202 to horizontally limit the limiting slider 201, thereby horizontally limiting the moving block 106 and making it easier for the moving block 106 to move as the screw rod 104 rotates.
[0027] Further, as Figure 1 shown, fixing bolts 3 are threadedly connected to the surface of the lug body 1; the number of the fixing bolts 3 is four; the fixing bolts 3 are evenly distributed on the surface of the lug body 1. During operation, the lug is installed and fixed through the cooperation of the fixing bolts 3 and nuts, reducing the probability of the lug detaching by welding and making the fixing effect of the lug better.
[0028] Further, as Figure 2As shown in the figure, both sides of the lug body 1 are fixedly connected with first reinforcing ribs 4; the first reinforcing ribs 4 are symmetrically distributed on the surface of the lug body 1; both sides of the lug body 1 are fixedly connected with second reinforcing ribs 5; the second reinforcing ribs 5 are symmetrically distributed on the surface of the lug body 1; during operation, the first reinforcing ribs 4 and the second reinforcing ribs 5 are used to assist in strengthening the lug body 1, reducing the probability of the lug body 1 breaking, and thus extending the service life of the lug.
[0029] Further, as Figure 1 shown, an anti-slip pad 6 is fixedly connected to the inner side of the lug body 1, and the material of the anti-slip pad 6 is rubber; during operation, by contacting the anti-slip pad 6 with the rope, the wear between the rope and the lug body 1 is reduced, the service life of the lug body 1 is extended, and the probability of the rope breaking is reduced.
[0030] Further, as Figure 3 shown, a limit bearing 7 is sleeved and connected to one end of the screw rod 104, and the limit bearing 7 is fixedly connected to the surface of the lug body 1; during operation, the screw rod 104 rotates on the lug body 1 through the limit bearing 7, the screw rod 104 is limited, the wear of the screw rod 104 is reduced, and the service life of the screw rod 104 is extended.
[0031] Working principle: When the object is heavy, the rotating disc 105 on the screw rod 104 is rotated through the grip 112, the rotating disc 105 drives the screw rod 104 to rotate, the screw rod 104 drives the moving block 106 to move, the moving block 106 drives the first connecting rod 107 to move, the first connecting rod 107 drives the second connecting rod 108 to move, the second connecting rod 108 drives the sliding block 109 to slide in the sliding groove 111, and then the sliding block 109 drives the reinforcing plate 110 to move, so that the reinforcing plate 110 contacts and fits with the lug body 1. By passing the hoisting rope through the reinforcing plate 110 and the lug body 1, the contact area between the lug and the rope is increased, thereby strengthening the lug and reducing the damage to the lug. The limit slider 201 is driven by the moving block 106 to slide on the limit slide bar 202, and the limit slider 201 is horizontally limited, so as to horizontally limit the moving block 106, making the moving block 106 move more easily when rotating with the screw rod 104. The lug is installed and fixed by the cooperation of the fixing bolt 3 and the nut, reducing the probability of the lug detaching by welding, making the fixing effect of the lug better. Through the first reinforcing ribs 4 and the second reinforcing ribs 5, the lug body 1 is assisted in strengthening, reducing the probability of the lug body 1 breaking, and thus extending the service life of the lug. By contacting the anti-slip pad 6 with the rope, the wear between the rope and the lug body 1 is reduced, the service life of the lug body 1 is extended, and the probability of the rope breaking is reduced.
