Description

Technical Field

[0001] This utility model relates to the field of bridge crane technology, specifically to a bridge crane balancing and stabilizing device. Background Technology

[0002] Bridge cranes are lifting equipment that spans across workshops, warehouses, and material yards for material handling. Because their two ends are supported by tall concrete pillars or metal supports, resembling a bridge, the bridge frame of a bridge crane runs longitudinally along tracks laid on elevated structures on both sides. This allows for full utilization of the space beneath the bridge frame for material handling, without being obstructed by ground equipment. It is the most widely used and numerous type of lifting machinery.

[0003] Bridge cranes handle a wide variety of goods with different shapes, sizes, and center of gravity distributions. For some irregularly shaped, off-center, or heavy goods, it is more difficult to achieve balanced lifting during the hoisting process, which increases the difficulty and risk of the operation. Therefore, there is an urgent need for a bridge crane balancing and stabilizing device to overcome the above-mentioned defects. Utility Model Content

[0020] This utility model provides, for example Figure 1-4As shown, a balancing and stabilizing device for a bridge crane includes a bridge crane body 1, a fixing clamping assembly 2, a leveling assembly 3, and a bottom supporting assembly 4. The fixing clamping assembly 2 is located at the bottom of the bridge crane body 1. The leveling assemblies 3 are located on the front and back of the fixing clamping assembly 2. The bottom supporting assemblies 4 are located on both sides of the bottom of the fixing clamping assembly 2. The leveling assembly 3 includes a second slide groove 31, a mounting base 32, a second motor 33, a second threaded rod 34, a second slider 35, and a counterweight 36. The bottom supporting assembly 4 includes a U-shaped seat 41, a turntable 42, a third threaded rod 43, a tray 44, a third slide groove 45, and a third slider 46. The fixing clamping assembly 2 includes a fixed crossbeam 21, a first slide groove 22, a first slider 23, a fixing claw 24, a first threaded rod 25, and a first motor 26.

[0021] More specifically, by setting the bottom support component 4 to support and limit the hoisted object, its stability is further improved. During hoisting, the hoisted object is first placed in the designated position, then the first motor 26 is turned on. The first motor 26 drives the first threaded rod 25 to rotate, causing the first slider 23 to drive the fixing claw 24 to move inward. Under the action of the fixing claw 24, the hoisted object is fixed. After fixing, the turntable 42 is rotated, which drives the third threaded rod 43 to rotate, causing the U-shaped seat 41 to move inward and support the hoisted object. Then, leveling is performed, the second motor 33 is turned on, which drives the second threaded rod 34 to rotate, causing the second slider 35 to drive the counterweight 36 to move to the designated position, so that it is in a horizontal position, which has the advantages of balance and stability.

[0022] In some embodiments, a fixed crossbeam 21 is fixedly installed at the bottom of the bridge crane body 1. A first groove 22 is provided at the bottom of the fixed crossbeam 21.

More specifically, the first groove 22 is used to limit the first slider 23 to prevent the first slider 23 from shaking during movement. The first slider 23 is also used to limit the fixed claw 24.

[0023] In some embodiments, a first motor 26 is fixedly installed on the left side of the fixed crossbeam 21. The output shaft of the first motor 26 passes through the inner cavity of the first slide groove 22 and is fixedly connected to the left side of the first threaded rod 25. A fixing claw 24 is fixedly installed at the bottom of the first slider 23. A U-shaped seat 41 is provided at the bottom of the fixing claw 24. More specifically, the first motor 26 drives the first threaded rod 25, and the first slider 23 moves the position of the fixing claw 24.

[0024] In some embodiments, a third slide groove 45 is provided on both sides of the inner cavity of the U-shaped seat 41, and a third slider 46 is slidably connected inside the third slide groove 45. The side of the third slider 46 that is relatively close to each other is fixedly connected to both sides of the fixing claw 24. A tray 44 is fixedly installed on the inner side of the U-shaped seat 41. More specifically, by setting the third slide groove 45 to limit the third slider 46, the U-shaped seat 41 is indirectly prevented from shaking during movement.

[0025] In some embodiments, a third threaded rod 43 is rotatably connected to the interior of the U-shaped seat 41 via a thread. The side of the third threaded rod 43 that is relatively close to the fixed claw 24 that is relatively far away is rotatably connected to the side of the fixed claw 24 via a bearing. A turntable 42 is provided on the side of the U-shaped seat 41 that is relatively far away. The side of the turntable 42 that is relatively close to the third threaded rod 43 is fixedly connected to the side of the third threaded rod 43 that is relatively far away. More specifically, the position of the U-shaped seat 41 and the tray 44 is indirectly adjusted by driving the third threaded rod 43 through the turntable 42.

[0026] In some embodiments, the fixed crossbeam 21 has a second slide groove 31 on both the front and back sides. A second slider 35 is slidably connected inside the second slide groove 31. A counterweight 36 is fixedly installed on the side of the second slider 35 that is relatively far away from the other side. A second threaded rod 34 is rotatably connected inside the second slider 35 by a thread. More specifically, the second slide groove 31 is used to limit the second slider 35 to prevent the second slider 35 from shaking during movement. The second slider 35 is also used to limit the counterweight 36 to prevent the counterweight 36 from shaking during movement.

[0027] In some embodiments, two mounting seats 32 are fixedly installed on both the front and back of the fixed crossbeam 21. The interior of the mounting seat 32 is rotatably connected to the surface of the second threaded rod 34 through bearings. A second motor 33 is fixedly installed on the left side of the mounting seat 32. The output shaft of the second motor 33 is fixedly connected to the left side of the second threaded rod 34. More specifically, the second motor 33 drives the second threaded rod 34, and the second slider 35 moves the counterweight 36.

[0028] Working principle:

[0029] Step 1: During hoisting, first place the object to be hoisted in the designated position, then turn on the first motor 26. The first motor 26 drives the first threaded rod 25 to rotate, causing the first slider 23 to drive the fixing claw 24 to move inward. Under the action of the fixing claw 24, the object to be hoisted is fixed. After fixing, rotate the turntable 42, which drives the third threaded rod 43 to rotate, causing the U-shaped seat 41 to move inward and support the bottom of the object to be hoisted.

[0030] Step 2: Next, level the position by turning on the second motor 33. The second motor 33 drives the second threaded rod 34 to rotate, which causes the second slider 35 to move the counterweight 36 to the designated position, making it horizontal and providing the advantage of balance and stability.
