During lubrication, when the alignment wheel 6 rotates in the forward direction, the turntable 24 is driven to rotate by the limiting mechanism. When the tooth groove 27 along the edge of the turntable 24 rotates to drive one side of the half gear 28, the dial plate 26 will dial the dial rod 29 to rotate, thereby prompting the half gear 28 to be stuck in the tooth groove 27, thereby prompting the half gear 28 to rotate, thereby prompting the first umbrella-shaped tooth 32 to drive the slider 45 behind to move, thereby prompting the driving assembly to drive the lubricating assembly to complete the lubrication of the connection of the cross connecting frame 2. At the same time, by only setting the tooth groove 27 on the edge of the turntable 24, the half gear 28 can only rotate when it contacts the tooth groove 27, thereby achieving the effect of intermittent output of lubricating oil, thereby prompting the lubricating oil to be used for a long time.

[0029] like Figures 1 to 6 As shown, the limiting mechanism includes a second ratchet 15 fixedly connected to one side of a rotating disk 24 through an axis, the rotating disk 24 and the second ratchet 15 are connected to the third bracket 21 on the outside of the axis, a plurality of ratchet grooves are provided on the outside of the second ratchet 15, one side of the second ratchet 15 is connected to a connecting plate 16 through an axis, a side of the connecting plate 16 away from one end of the second ratchet 15 is fixedly connected to a pressure column 19, one side of the pressure column 19 is connected to an arc plate 17 through an axis, a triangular block 18 is fixedly connected to the top of the arc plate 17, the size of the triangular block 18 is matched with the size of the ratchet groove on the outside of the second ratchet 15, and the triangular block 18 is snapped into the inside of the ratchet groove, and the first A resisting frame 20 is installed on one side of the second ratchet 15, and the top of the resisting frame 20 contacts the bottom of the pressure column 19. The side of the second ratchet 15 away from the connecting plate 16 is connected to the rotating wheel 13 through an axis rotation. The side of the rotating wheel 13 opposite to the second ratchet 15 is annularly and equidistantly fixedly connected with three shifting posts 14. When the shifting posts 14 contact the bottom end of the arc plate 17, the triangular block 18 pushes the second ratchet 15 to rotate. A return spring 23 is fixedly connected to one side of the arc plate 17 close to one end of the triangular block 18. A connecting column 22 is fixedly connected to one side of one end of the third bracket 21. The end of the return spring 23 away from the arc plate 17 is fixedly connected to one side of the connecting column 22. By setting the limiting mechanism, the rotation of the limiting lever 14 can be achieved. When there is no lubrication, in order to prevent the turntable 24 from rotating on its own, the second ratchet 15 will be limited by the return spring 23 and the pressure column 19, thereby preventing the turntable 24 from rotating on its own and causing the lubricating oil to automatically flow out. The problem of limiting the rotation of the turntable 24 can be solved. During lubrication, when the alignment wheel 6 rotates forward, it will drive the turntable 13 to rotate. Under the continuous drive of the alignment wheel 6, the lever 14 will rotate to the bottom end of the arc plate 17. At this time, the lever 14 will move against the arc plate 17, and at the same time, the triangular block 18 at the top of the arc plate 17 will rotate against the second ratchet 15, thereby prompting the second ratchet 15 to drive the turntable 24 to rotate. , thereby prompting the lubrication component at the rear to be lubricated. By setting the pressure column 19 and the return spring 23, when the rotating wheel 13 rotates forward, the arc plate 17 will pull the return spring 23, and at the same time, the arc plate 17 brings the pressure column 19 away from the top of the blocking frame 20, thereby prompting the triangular block 18 to rotate against the second ratchet 15. At the same time, when the lever 14 on one side of the rotating wheel 13 rotates past the bottom end of the arc plate 17, the return spring 23 automatically returns and the return spring 23 pulls the top of the arc plate 17 to move downward, thereby prompting the pressure column 19 to contact the top of the blocking frame 20 again, thereby limiting the movement of the arc plate 17 and also limiting the rotation of the second ratchet 15, thereby avoiding the problem of the turntable 24 rotating on its own.

[0030] like Figures 1 to 8 As shown, the side of the rotating wheel 13 away from the second ratchet 15 is fixedly connected to the first connecting wheel 9 through an axis, the first connecting wheel 9 is connected to the rotating wheel 13 and is rotatably connected to the second bracket 12 on the outside of the axis, the first connecting wheel 9 is connected to the rotating wheel 13 and is rotatably connected to the first ratchet 8 on the side of the first connecting wheel 9 away from the rotating wheel 13, a plurality of fixed columns are fixedly connected to the first connecting wheel 9 in an annular shape, a plurality of first ratchet clamps 10 are rotatably connected to the first connecting wheel 9 on the side of the first connecting wheel 9, one end of the first ratchet clamps 10 is engaged with the outside of the first ratchet 8, and a rebound spring 11 is fixedly connected to one side of the other end of the first ratchet clamp 10, one end of the rebound spring 11 away from the first ratchet clamp 10 is fixedly connected to one side of the fixed column, the side of the first ratchet 8 away from the first connecting wheel 9 is fixedly connected to the alignment wheel 6 through an axis, the first ratchet 8 is connected to the alignment wheel 6 and is rotatably connected to the first bracket 7 on the outside of the axis, and the position of the alignment wheel 6 corresponds to the position of the rack 5; By setting the first ratchet 8 and the first connecting wheel 9, when the alignment wheel 6 rotates forward, the first ratchet 8 will engage with one end of the first ratchet 10, thereby prompting the first ratchet 8 to rotate forward with the first connecting wheel 9, thereby prompting the rear slider 45 to carry the metering cylinder 47 away from the bottom of the oil storage cylinder 41, thereby completing the automatic output of the lubricating oil. At the same time, when the rack 5 descends, it will drive the alignment wheel 6 to rotate in the opposite direction, thereby prompting the first ratchet 8 to disengage from the first ratchet 10, thereby avoiding the problem of reversal of the first connecting wheel 9 and reversal of the rear rotating wheel 13, thereby avoiding affecting the use of the limiting mechanism, and at the same time achieving the effect of intermittently rotating the alignment wheel 6 to drive the rotating wheel 13 to rotate, thereby extending the interval time of lubricating oil output, which is beneficial to the long-term use of the lubricating oil in the later stage.

A connecting column 53, the first connecting column 53 is fixedly connected to both sides of each connection of the cross connecting frame 2 away from the third connecting block 72 and the fourth connecting block 58, a positioning rope 54 is fixedly connected to the bottom of the first connecting column 53, and the end of the positioning rope 54 away from the first connecting column 53 is fixedly connected to the second connecting column 55, and a receiving box 56 is fixedly connected to the middle of the two second connecting columns 55, and the bottom of the receiving box 56 is connected to a transmission tube 57, and a bottom box 60 is fixedly connected to the bottom of the bottom frame seat 1, and the position of the bottom box 60 is located at the bottom where the bottom frame seat 1 and the cross connecting frame 2 meet, and the position of the output end of the transmission tube 57 is located at the top of the bottom box 60, and the first umbrella-shaped tooth 32 is fixedly connected to the outside of the connecting shaft of the half gear 28 with a driving wheel 31, and one side of the driving wheel 31 is connected to a driven wheel 61 through a belt drive, and one side of the driven wheel 61 is fixedly connected to the first umbrella-shaped tooth 32 on the other side of the fixed frame 4 through an axis; By means of the provided flow guide assembly, the lubricating oil can be effectively guided to each key connection of the cross connecting frame 2, thereby ensuring the lubrication effect of each connection, making the operation of the entire lifting structure more stable and reliable. At the same time, through the design of the delivery pipe 52 and the receiving box, not only can the lubricating oil be accurately guided to the part that needs lubrication, thereby improving the efficiency and effect of lubrication, but also avoiding the waste of lubricating oil. During lubrication, when the lubricating oil is input into the interior of the alignment box 46, the lubricating oil will be input into the interior of the three delivery pipes 52. At the same time, through the guidance of the delivery pipe 52, the lubricating oil is prompted to flow to the top of the cross connecting frame 2 At both ends and the middle of the part, the lubricating oil will first flow to the connection between the cross connecting frame 2 and the top frame 3 for lubrication, and then the excess lubricating oil will flow into the inside of the receiving box 56 and the second receiving box 58, and at the same time, it will flow to the connection between the two cross connecting frames 2 through the guidance of the transmission pipe 57 for lubrication. At the same time, the excess lubricating oil at both ends of the cross connecting frame 2 will flow into the inside of the receiving box 56 and be guided to the connection between the cross connecting frame 2 and the bottom frame seat 1 through the transmission pipe 57 for lubrication. Finally, the excess lubricating oil at both ends of the bottom of the cross connecting frame 2 will flow to the inside of the bottom box 60 for collection. The last lubricating oil in the middle of the cross-connecting frame 2 will flow to the second receiving box 58 at the bottom of the middle of the cross-connecting frame 2 for collection, thereby avoiding the waste of lubricating oil. At the same time, by setting the driving wheel 31 and the driven wheel 61, by setting the oil storage barrel 41 on both sides of the bottom frame seat 1, during lubrication, the first umbrella-shaped tooth 32 rotates forward, and at the same time drives the driving wheel 31 to rotate, thereby prompting the driven wheel 61 to drive the first umbrella-shaped tooth 32 on the other side of the bottom frame seat 1 to rotate, thereby prompting the oil storage barrel 41 on both sides of the bottom frame seat 1 to output lubricating oil at the same time, thereby lubricating the connection between the cross-connecting frames 2 at the top of the two sides of the bottom frame seat 1.

At the same time, through the provided movable groove 67, telescopic rod 68 and alignment cylinder 69, when the cross-connecting frame 2 is raised or lowered and the second connecting block 71 slides, the telescopic rod 68 will be raised or lowered inside the top of the alignment cylinder 69 and the conveying pipe 52 on the top of the second connecting block 71 will slide inside the movable groove 67.
