[0024] The following will describe the present utility model in detail in combination with the specific embodiments shown in the drawings. However, these embodiments do not limit the present utility model, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these embodiments is included in the protection scope of the present utility model.

[0025] As Figures 1 to 7 shown, the present utility model provides a moving trolley capable of electrically vertically unsealing and moving a cover plate, including:

[0026] A fixed frame 1, with pulleys 2 fixedly installed on both the front and rear sides of the inner top of the fixed frame 1. A first steel wire rope 3 is movably connected inside the pulley 2. The bottom end of the first steel wire rope 3 is fixedly installed with a second steel wire rope 4. A moving rod 5 is movably sleeved on the outer surface of the second steel wire rope 4. A round rod 6 is movably sleeved inside the moving rod 5. A fixed plate 7 is fixedly installed on the outer surface of the moving rod 5. A long groove 8 is opened on the outer surface of the fixed plate 7. A clamping arm 9 is movably sleeved inside the fixed plate 7;

[0027] A telescopic mechanism, which is arranged on the outer surface of the moving rod 5;

[0028] Among them, the telescopic mechanism includes a round shaft 10. The back surface of the round shaft 10 is fixedly connected to the front surface of the moving rod 5. A gear 11 is movably sleeved on the outer surface of the round shaft 10. The back surface of the gear 11 is movably connected to the front surface of the moving rod 5. The outer surface of the gear 11 is meshed with a rotating rod 12. The inner part of the rotating rod 12 is movably sleeved on the outer surface of the round rod 6. The back surface of the rotating rod 12 is movably connected to the front surface of the moving rod 5. The inner part of the other end of the rotating rod 12 is movably sleeved with a movable rod 13. The inner part of the other end of the movable rod 13 is movably sleeved with a moving shaft 14. The other end of the moving shaft 14 extends into the fixed plate 7 through the long groove 8. The other end of the moving shaft 14 is fixedly connected to the front surface of the clamping arm 9.

[0029] When the gear 11 rotates around the round shaft 10, the rotating rod 12 will rotate around the round rod 6 driven by the gear 11, and then the other end of the rotating rod 12 will drive the movable rod 13 to move, and then the movable rod 13 will drive the moving shaft 14 to move. Due to the limiting effect of the long groove 8, the moving shaft 14 will drive the clamping arm 9 to move along the inside of the fixed plate 7 to the outside of the fixed plate 7.

[0030] Among them, a limit block 15 is fixedly installed on the right side of the front of the moving rod 5, a short slot 16 is opened on the front of the limit block 15, a moving block 17 is movably sleeved inside the limit block 15, one end of the front of the moving block 17 extends to the outside of the limit block 15 through the short slot 16, a spring 18 is fixedly installed on the right side of the moving block 17, one end of the right side of the spring 18 is fixedly connected to the inside of the limit block 15, a stopper 19 is fixedly installed on the left side of the moving block 17, the other end of the stopper 19 passes through the inside of the limit block 15 and extends to the outside of the limit block 15, and the other end of the stopper 19 is movably connected to the outer surface of the gear 11.

[0031] When the stopper 19 contacts the outer surface of the gear 11, the stopper 19 will block the rotation of the gear 11. Due to the limiting effect of the short slot 16, the moving block 17 can only move left and right. When the moving block 17 drives the stopper 19 to move right, the stopper 19 will release the blocking effect on the gear 11 during the rightward movement. At the same time, the spring 18 will be in a compressed state. Due to the elastic force of the spring 18, the movement of the moving block 17 will have a good resetting effect.

[0032] Among them, a moving plate 20 is fixedly installed at the bottom end of the right side of the fixed frame 1, and the right sides of the front and rear ends of the moving plate 20 are movably connected with limiting plates 21, and the outer surfaces of the left and right sides of the limiting plates 21 are fixedly installed with a trolley body 22, and rollers 23 are fixedly installed on the left and right ends of the front and rear sides of the bottom of the trolley body 22.

[0033] Due to the limiting effect of the two limiting plates 21, the moving plate 20 as a whole can only move left and right, and due to the design of the four rollers 23, the trolley body 22 as a whole can move smoothly.

[0034] Among them, a dual-axis motor 24 is fixedly installed on the right side of the top of the moving plate 20, and the other end of the output shaft of the dual-axis motor 24 is fixedly sleeved with a rotating shaft 25, and the other end of the rotating shaft 25 is fixedly sleeved with a round block 26, and the outer surface of the round block 26 is fixedly connected to the other end of the first steel wire rope 3.

[0035] When the dual-axis motor 24 is running, the two rotating shafts 25 will drive the two round blocks 26 to rotate. At this time, the two round blocks 26 will wind the two first steel wire ropes 3 during rotation, and then the second steel wire rope 4 will move upward as a whole.

[0036] Among them, a fixing frame 27 is fixedly installed at the bottom end of the limit plate 21, a driving motor 28 is fixedly installed at the bottom end of the fixing frame 27, the other end of the output shaft of the driving motor 28 is fixedly sleeved with a rotating shaft 29, and the other end of the rotating shaft 29 penetrates through the bottom end of the fixing frame 27 and extends into the interior of the fixing frame 27.

[0037] When the driving motor 28 operates, the rotating shaft 29 will rotate at this time.

[0038] Among them, the other end of the rotating shaft 29 is fixedly sleeved with a rotating rod 30, the inside of the other end of the rotating rod 30 is fixedly sleeved with a pressing shaft 31, the outer surface of the pressing shaft 31 is movably connected with a movable block 32, and the top end of the movable block 32 is fixedly connected with the bottom end of the moving plate 20.

[0039] When the rotating shaft 29 drives the pressing shaft 31 to rotate through the rotating rod 30, the outer surface of the pressing shaft 31 will squeeze and push the inside of the movable block 32 during rotation, so that the movable block 32 drives the entire moving plate 20 to move. At this time, the entire moving plate 20 will move to the left under the limitation of the two limit plates 21.

[0040] The working principle and usage process of the utility model:

[0041] First, the operator starts the driving motor 28. At this time, the rotating shaft 29 will rotate. At this time, the rotating rod 30 will rotate under the drive of the rotating shaft 29. Then, the pressing shaft 31 will rotate around the rotating shaft 29 under the drive of the rotating rod 30. At this time, the pressing shaft 31 will squeeze the inside of the movable block 32 during rotation to make the movable block 32 move. Subsequently, the movable block 32 will drive the entire moving plate 20 to move. Due to the design inside the two limit plates 21, the movement of the entire moving plate 20 will be limited, so that the entire moving plate 20 can only move left and right. At this time, the movable block 32 will drive the entire moving plate 20 to move to the left, thus realizing the function of preventing the larger-sized cover plate from colliding with the trolley body 22 when being clamped.

[0042] Then the operator pulls the moving block 17 along the inside of the short slot 16. Due to the design of the short slot 16, the movement of the moving block 17 will be limited so that it can only move left and right. At this time, the moving block 17 will move to the right along the inside of the short slot 16. At this time, the spring 18 will be in a compressed state. At the same time, the block 19 will move to the right driven by the moving block 17. At this time, the outer surface of the block 19 will separate from the outer surface of the gear 11 during the rightward movement. At this time, the block 19 will release the blocking effect on the gear 11. Then the operator rotates the gear 11 with the circular shaft 10 as the axis. Since the gear 11 is meshed with the rotating rod 12, the gear 11 will drive the rotating rod 12 to rotate around the round rod 6 during rotation. At this time, the other end of the rotating rod 12 will drive the movable rod 13 to move, and then the other end of the movable rod 13 will drive the moving shaft 14 to move. Due to the design inside the long groove 8, the movement of the moving shaft 14 will be limited so that it can only move left and right. At this time, the moving shaft 14 will move to the left, and then the moving shaft 14 will drive the clamping arm 9 to move to the left along the inside of the fixed plate 7, thereby realizing the function of extending and retracting the clamping arm 9 according to the size of the cover.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
