Description

Technical Field

[0001] The utility model relates to the technical field of crane equipment, in particular to a universal bridge crane. Background Art

[0002] A bridge crane is a type of lifting equipment used to lift materials across workshops, warehouses, and material yards. Because its ends rest on tall concrete columns or metal supports, it resembles a bridge. The bridge of a bridge crane runs longitudinally along tracks laid on elevated structures on both sides, fully utilizing the space beneath it to lift materials without being obstructed by ground-based equipment. It is the most widely used and numerous type of lifting machinery. Because bridge cranes are used to lift heavy objects, the inertia of the load hoisted below can cause the trolley to sway as it moves, affecting its stability and causing the trolley to sway slightly, even causing it to overturn and cause accidents.

[0003] The patent, with publication number "CN219489392U," is titled "A Bridge Crane." The device described in this publication addresses the aforementioned issues, but the hook only serves to prevent cargo from falling off. Once the cargo is lifted by the hook, the hook fails to secure the hooked portion. This causes the connection between the cargo and the hook to wobble, resulting in continued oscillation of the cargo even when it is moved. This utility model addresses these issues by designing a universal bridge crane. Utility Model Content

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.

[0025] Example 1

[0026] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5As shown, the device includes a bracket 1, a first motor 2 and a rotating rod 3. The first motor 2 is fixed to the left side of the top of the bracket 1, and the rotating rod 3 is fixed to the right side of the first motor 2. The rotating rod 3 is connected to the bracket 1 by a transfer. A displacement component 4 is provided inside the bracket 1. The displacement component 4 includes a slider 401 that is slidably connected to the top of the bracket 1. The slider 401 is threadedly sleeved on the outside of the rotating rod 3. A mounting plate 402 is fixed to the bottom of the slider 401. The front and rear ends of the mounting plate 402 are transferred with a rotating shaft 403, and the left and right sides of the rotating shaft 403 are fixedly sleeved with push plates 404. A limiting assembly 5 is provided at the lower end of the mounting plate 402, and the limiting assembly 5 includes a support plate 501 provided at the lower end of the mounting plate 402, support blocks 502 are slidably connected at the four corners inside the support plate 501, and the support blocks 502 are connected to the push plate 404 by a transfer connection, and a number of hooks 503 are fixedly provided at the bottom of the support plate 501, a second motor 504 is fixedly provided on the middle side of the support plate 501, a screw rod 505 is fixedly provided on the top of the second motor 504, a connecting plate 506 is provided on the external threaded sleeve of the screw 505, and limiting rods 507 are fixedly provided at the four corners at the bottom of the connecting plate 506.

[0027] First, a large number of hooks 503 can suspend multiple areas of the cargo, and the staff then turns on the forward rotation of the second motor 504, which drives the screw 505 to rotate. Through the threaded transmission of the screw 505 and the connecting plate 506, the connecting plate 506 drives the limiting rod 507 to move along the direction of the cargo, thereby causing the limiting rod 507 to exert a clamping force on the top surface of the cargo. After the clamping force of the limiting rod 507 on the top surface of the cargo meets the staff's requirements, the staff turns off the second motor 504 and turns it on again. The first motor 2 drives the rotating rod 3 to rotate, and through the threaded transmission of the rotating rod 3 and the slider 401, the slider 401 drives the mounting plate 402 to link the rotating shaft 403, the push plate 404, the support plate 501 and the cargo to move along the lateral direction of the bracket 1. At this time, the limiting rod 507 exerts multiple-point squeezing on the top surface of the cargo to limit the swing of the connection area between the cargo and the hook 503. In addition, the self-locking force of the slider 401 and the rotating rod 3 threads ensures the locking effect of the cargo after lateral displacement.

[0028] Example 2

[0029] like Figure 1 、 Figure 2 、 Figure 3As shown, the two brackets 1 are in a parallel design state, the limit rod 507 slides through the support plate 501, the screw 505 is set between the mounting plate 402 and the support plate 501, the number of brackets 1 is two, the side cross-section of the slider 401 and the support block 502 is an I-shaped design, the hook 503 and the support plate 501 can be disassembled and processed by threaded connection, the top front end of the mounting plate 402 is fixed with a third motor 6, the rear end of the third motor 6 is fixed with a worm 7, the worm 7 is connected to the slider 401 at the rear end, and the mounting plate 40 2 The front and rear ends of the interior are integrally provided with clearance holes 8. The clearance holes 8 are through holes and correspond one-to-one with the rotating shaft 403. A worm gear 9 is provided inside the clearance hole 8. The worm gear 9 is fixedly sleeved on the outside of the rotating shaft 403. The worm gear 9 is engaged with the worm 7. The worm gear 9 at the rear end is designed to be connected with the worm 7 in a left-hand thread, while the worm gear 9 at the front end is designed to be connected with the worm 7 in a right-hand thread. The mounting plate 402, the connecting plate 506 and the support plate 501 are designed to be parallel. The connecting plate 506 is provided between the mounting plate 402 and the support plate 501.

[0030] According to the operation method in Example 1, the staff can turn on the third motor 6, and the third motor 6 drives the worm 7 to drive the worm wheel 9 to rotate the linkage shaft 403 and the push plate 404. The rotating push plate 404 pushes or pulls the support block 502 together with the support plate 501 to move in the direction or opposite direction of the mounting plate 402, thereby causing the support plate 501 to drive the hook 503 together with the cargo to move along the longitudinal direction of the bracket 1. In addition, the self-locking force of the worm 7 and the worm wheel 9 ensures the locking effect after the longitudinal displacement of the cargo, and the clearance hole 8 makes room for the worm wheel 9 to rotate.
