[0020] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] like Figures 1 to 4 As shown, this embodiment proposes a beam crane for preparing and processing floor beams, including a beam 1, a jack 3 movably installed on the upper end of the beam 1, a motor 20 fixedly installed on the upper end of the jack 3, a gear 2 fixedly installed on the output end of the motor 20, a rack 4 meshingly connected at the lower end of the gear 2, support frames 10 are installed at both ends of the rack 4, a first motor 5 is fixedly installed on one group of support frames 10, a lead screw 19 is fixedly installed on the output end of the first motor 5, a lifting rod 6 is fixedly installed on the lower end of the jack 3, a clamping assembly 7 is fixedly installed on the lower end of the lifting rod 6, and an adjustment assembly 8 is installed on the upper end of the clamping assembly 7; the beam 1 and the rack 4 are adjusted forward and backward through the mutual cooperation between the first motor 5 and the lead screw 19.

[0023] In this embodiment, the first motor 5 drives the lead screw 19 to rotate, and the lead screw 19 drives the rack 4 and the beam 1 to adjust forward and backward on the support frame 10, thereby improving the practicality of the equipment. In addition, a slide groove 9 is provided on another set of support frames 10, and a block is fixedly installed at the lower end of the beam 1 corresponding to the slide groove 9, which can assist the rack 4 and the beam 1 in adjusting forward and backward, thereby extending the service life of the lead screw. At the same time, the second motor provided on the jack 3 drives the gear 2 to rotate by the motor 20, and the gear 2 is engaged with the rack, and then the jack is driven by the motor 2 0. The gear 2 and the rack 4 cooperate with each other to adjust the beam 1 to the left and right, and the arrangement of the rack 4 and the gear 2 allows the motor 20 to drive the rack 4 to rotate, and the motor 20 then drives the jack 3 to move and adjust. When the motor 20 stops, the gear 2 no longer rotates. The gear 2 is engaged with the rack 4, and the jack 3 can be engaged to prevent the jack 3 from deviating in a certain direction with the floor beam due to inertia when the staff adjusts the jack 3 to the left and right. The jack model is XYLC-2T.

[0024] Example 2

[0025] like Figures 1 to 4As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the adjustment component 8 includes a second motor 11, a movable plate 12, an adjustment plate 13, a threaded rod 14, a second bevel gear 15 and a first bevel gear 16. The second motor 11 is fixedly mounted on the adjustment component 8, and the output end of the second motor 11 is fixedly mounted with the first bevel gear 16. Both ends of the first bevel gear 16 are meshed with the second bevel gear 15. One end of the two sets of second bevel gears 15 is fixedly mounted with a threaded rod 14, and the other end of the two sets of threaded rods 14 is fixedly mounted with The movable plate 12 and the adjustment plate 13 are fixedly installed at the connection of the two groups of movable plates 12; the clamping assembly 7 includes a clamping plate 17 and an automatic telescopic rod 18, the clamping plate 17 is fixedly installed on the clamping assembly 7, and the left and right ends of the clamping plate 17 are fixedly installed with automatic telescopic rods 18, and the middle of the clamping plate 17 is arranged in a cavity; the clamping plate 17 is adjusted forward and backward through the mutual cooperation between the second motor 11, the movable plate 12, the adjustment plate 13, the threaded rod 14, the second bevel gear 15, and the first bevel gear 16; the two groups of threaded rods 14 are arranged with forward and reverse threads.

[0026] In this embodiment, the floor beam can be clamped and transported by the clamping assembly 7, and the clamping plate 17 can be driven by the second motor to rotate the first bevel gear 16, and then the first bevel gear 16 engages the second bevel gears 15 at both ends, and the second bevel gear 15 drives the threaded rod 14 to rotate, and the threaded rod 14 drives the movable plate 12 to adjust left and right, and then the movable plate 14 drives both ends of the supporting plate 17 to adjust left and right, and the two sets of threaded rods 14 are set to forward and reverse threads, which can be adjusted synchronously with the two sets of movable plates 12, so that the clamping plate 17 can adjust floors of different sizes. The floor beam is clamped, and the setting of the clamping plate 17 is more in line with the shape of the floor beam than the hook, so that when the hook clamps the floor beam for lifting, the floor beam is not subjected to uneven force on both sides, which causes the floor beam to swing in the air, increasing the safety risk of transportation. At the same time, the lifting rod 6 set at the lower end of the lifter 3 can lift and transport the floor beam, and the setting of the lifting rod 6 makes the clamping assembly 7 more stable when transporting and lifting the floor beam, so that when the hook transports the floor beam, the floor beam is not affected by inertia and swings in the air, which easily causes the center of gravity of the floor beam to be unstable and fall.

[0027] During operation, the first motor 5 is first started, and the first motor 5 drives the lead screw 19 to rotate, and then the lead screw 19 drives the rack 4 and the beam 1 to adjust forward and backward. After the rack 4 and the beam 1 are adjusted to the appropriate position, the motor 20 is used to drive the gear 2 to rotate, and the gear 2 is engaged with the rack 4, thereby driving the jack 3 to adjust left and right. After the jack 3 is adjusted to the appropriate position, the lifting rod 6 is controlled by the jack 3, and then the lifting rod 6 drives the clamping assembly 7 to clamp the floor beam. The clamping plate drives the first bevel gear 16 to rotate through the second motor, and then the first bevel gear 16 engages the second gears at both ends. The bevel gear 15 is driven by the second bevel gear 15 to rotate the threaded rod 14, and the threaded rod 14 drives the movable plate 12 to adjust left and right, and then the movable plate 14 drives the two ends of the supporting plate 17 to adjust left and right, and the two groups of threaded rods 14 are set to forward and reverse threads, which can lead the two groups of movable plates 12 to adjust synchronously, so that the clamping plate 17 can clamp floor beams of different sizes. After the clamping plate 17 is adjusted to the appropriate position, the ground beam is clamped, and then the floor beam is fixed on the clamping plate through the automatic telescopic rod 18. After the floor beam is clamped and fixed, the floor beam is lifted and transported by the jack 3 and the lifting rod 6.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
