DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] like Figures 1 to 6 As shown, the utility model provides a special lifting device for lifting a hydrogenation reactor, including:
[0031] A cross arm 1, a connecting block 2 is movably mounted in the middle of the top of the cross arm 1, a rectangular block 3 is fixedly sleeved on the outer surface of the connecting block 2, and a lifting ring 19 is fixedly mounted on the top of the rectangular block 3;
[0032] An adjusting mechanism 4, the adjusting mechanism 4 is arranged inside the cross arm 1;
[0033] A driving mechanism 5, which is arranged at the middle end of the cross arm 1;
[0034] Among them, the adjustment mechanism 4 includes a groove 401, which is opened at the bottom end of the cross arm 1, and the first slider 402 is movably sleeved at the left end inside the groove 401, and the first tooth plate 403 is fixedly installed on the top of the right end of the first slider 402, and the top of the first tooth plate 403 is movably connected to the left side of the top of the groove 401, and the right end of the groove 401 is movably sleeved with a second slider 404, and the second tooth plate 405 is fixedly installed at the bottom of the left end of the second slider 404, and the bottom end of the second tooth plate 405 is movably connected to the right side of the bottom end of the groove 401, and the movement of the first tooth plate 403 and the second tooth plate 405 realizes the adjustment of the distance between the first slider 402 and the second slider 404.
[0035] When the first tooth plate 403 and the second tooth plate 405 move toward each other along the inner surface of the groove 401, since the first tooth plate 403 and the second tooth plate 405 are fixedly connected to the first slider 402 and the second slider 404 respectively, the first slider 402 and the second slider 404 will move with the first tooth plate 403 and the second tooth plate 405. At this time, the distance between the first slider 402 and the second slider 404 will be reduced, so that the special lifting equipment for lifting the hydrogenation reactor can lift reactors of different specifications, thereby improving the applicability and convenience of the lifting equipment and reducing the cost of lifting and transporting the hydrogenation reactor.
[0036] Wherein, the driving mechanism 5 comprises:
[0037] A driving motor 501, the driving motor 501 is fixedly sleeved inside the middle end of the cross arm 1, and the other end of the output shaft of the driving motor 501 is fixedly sleeved with a driving shaft 502;
[0038] Gear 503, gear 503 is fixedly sleeved on the outer surface of the driving shaft 502, the outer surface of gear 503 is movably sleeved with the inner surface of the middle end of the cross arm 1, and the outer surface of gear 503 is meshed and connected with the outer surfaces of the first tooth plate 403 and the second tooth plate 405 respectively.
[0039] When the drive motor 501 is started, the drive shaft 502 will drive the gear 503 to rotate. Since the outer surfaces of the first tooth plate 403 and the second tooth plate 405 are meshed with the outer surface of the gear 503, the first tooth plate 403 and the second tooth plate 405 will move towards each other under the action of the gear 503.
[0040] Among them, the bottom ends of the first slider 402 and the second slider 404 are respectively hinged with a pushing arm 6, the number of which is two, the top ends of the two pushing arms 6 are hinged to each other, and the bottom ends of the two pushing arms 6 are both hinged with a clamping arm 7, the number of which is two, and the middle parts of the two clamping arms 7 are hinged to each other.
[0041] Due to the cooperation between the pushing arm 6 and the clamping arm 7, the hydrogenation reactor is clamped and fixed.
[0042] Among them, a pneumatic cylinder 8 is fixedly installed in the middle of the bottom end of the cross arm 1, and a rectangular plate 9 is fixedly installed at the bottom end of the pneumatic cylinder 8. A limiting rod 10 is fixedly sleeved on the inner surface of the rectangular plate 9. The left and right ends of the limiting rod 10 respectively penetrate the clamping arms 7 located on the left and right sides of the bottom end of the cross arm 1 and extend to the outside of the clamping arms 7.
[0043] When the pneumatic cylinder 8 is started, the rectangular plate 9 will move downward with the limiting rod 10, so that the clamping arm 7 can clamp and fix the hydrogenation reactor under the action of the pushing arm 6.
[0044] Among them, a fixed column 11 is fixedly sleeved in the middle of the top of the rectangular block 3, the bottom end of the fixed column 11 passes through the rectangular block 3 and the connecting block 2 and is movably connected to the top of the cross arm 1, and a round block 12 is movably sleeved at the bottom of the outer surface of the fixed column 11, the bottom end of the round block 12 is fixedly connected to the top of the cross arm 1, and the outer surface of the round block 12 is movably sleeved to the inner surface of the connecting block 2.
[0045] The outer surface of the fixing column 11 , the outer surface of the round block 12 and the inner surface of the round block 12 are all smooth, ensuring that there is no jamming when the round block 12 rotates.
[0046] A power motor 13 is fixedly mounted on the front end of the left inner wall of the rectangular block 3 , a rotating shaft 14 is fixedly sleeved on the other end of the output shaft of the power motor 13 , and a pushing block 15 is threadedly sleeved on the right side of the outer surface of the rotating shaft 14 .
[0047] When the power motor 13 is started, the rotating shaft 14 will rotate, and the pushing block 15 threadedly sleeved with the rotating shaft 14 will move to the left.
[0048] A limiting groove 16 is provided at the front side of the bottom end of the rectangular block 3 , and a limiting block 17 is movably sleeved on the right end of the limiting groove 16 , and the top of the limiting block 17 is fixedly connected to the bottom end of the pushing block 15 .
[0049] Due to the existence of the limiting groove 16 and the limiting block 17, the pushing block 15 is limited to prevent the pushing block 15 from deflecting when moving.
[0050] Among them, the front end of the pushing block 15 is hinged with a pushing rod 18, which is movably sleeved on the inner surface of the right end of the connecting block 2, and the other end of the pushing rod 18 is hinged to the right side of the front end of the round block 12. The movement of the pushing rod 18 will cause the round block 12 to rotate.
[0051] When the push block 15 moves, it will move with the right end of the push rod 18 , so that the left end of the push rod 18 pushes the round block 12 , causing the round block 12 to rotate around the axis of the fixed column 11 .
[0052] The working principle and use process of this utility model:
[0053] First, the operator connects the lifting rope to the lifting ring 19, and then moves the hydrogenation reactor to the bottom of the cross arm 1 by moving the lifting rope. When the length of the hydrogenation reactor is less than the distance between the two clamping arms 7, the operator starts the driving motor 501, so that the driving shaft 502 drives the gear 503 to rotate. Since the gear 503 is respectively meshed with the first tooth plate 403 and the second tooth plate 405, the first tooth plate 403 and the second tooth plate 405 will move the first slider 402 and the second slider 404 towards each other under the action of the gear 503, thereby aligning the first slider 402 and the second slider 404 located at the cross arm. The spacing of the clamping arms 7 on the left and right sides of the bottom end is adjusted until the length of the hydrogenation reactor is matched, and the driving motor 501 can be stopped, and then the pneumatic cylinder 8 is started to push the rectangular plate 9 and the limit rod 10 to move downward. As the limit rod 10 moves downward, the clamping arms 7 will rotate in the opposite direction with the limit rod 10 as the axis under the action of the pushing arms 6, so as to clamp and fix the hydrogenation reactor. At this time, the hydrogenation reactor can be lifted and transported by pulling the lifting rope. The mutual cooperation of various mechanisms enables the lifting sling to lift and transport hydrogenation reactors of different specifications, thereby improving its applicability.
[0054] After the hydrogenation reactor is hoisted to the designated position, if the position of the hydrogenation reactor needs to be adjusted, the operator can start the power motor 13 to rotate the shaft 14. Since the push block 15 is threadedly sleeved on the outer surface of the shaft 14, the push block 15 will move downward along the inner surface of the limit groove 16 with the rotation of the shaft 14, so that the left end of the push rod 18 generates a thrust on the round block 12, pushing the round block 12 to rotate with the cross arm 1 around the fixed column 11 as the axis, so that the hydrogenation reactor can be rotated, thereby adjusting its position, thereby improving the convenience of using the special hoist for lifting the hydrogenation reactor.
