Description

Technical Field

[0001] This invention relates to the field of crane technology, and specifically to a lightweight, single-beam suspended explosion-proof crane. Background Technology

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. Also known as an overhead crane, gantry crane, or single-girder crane, it is a lifting device that spans across workshops, warehouses, and material yards for material handling. Because its two ends rest on tall concrete pillars or metal supports, it resembles a bridge. The bridge frame of a single-girder crane runs longitudinally along tracks laid on elevated supports on both sides, making full use of the space beneath the bridge frame for material handling without obstruction from ground equipment. It is the most widely used and numerous type of lifting machinery. Some lifting equipment operates intermittently, meaning that the corresponding mechanisms for picking up, moving, and unloading materials work alternately within a work cycle. Cranes are becoming increasingly widespread in the market. Because they do not use outriggers for lifting heavy loads and frequently cause accidents while carrying heavy loads, their travel speed is faster than crawler cranes. They offer stable operation, large lifting capacity, and can travel while carrying heavy loads within a specific range, but it is essential to ensure that the road surface is flat and firm, the tire pressure meets requirements, and the load is not lifted more than 50 cm off the ground; long-distance travel under load is prohibited. To ensure operational safety, lifting operations without outriggers are generally prohibited in China. The types of wire ropes used with cranes include phosphated coated wire rope, galvanized wire rope, and bright wire rope.

[0003] However, in existing technologies, cranes typically have multiple power sources to drive their movement, enabling them to lift and move objects. However, multiple power sources can make the crane excessively heavy. Over time, this excessive weight leads to excessive wear and tear. Furthermore, when lifting lighter objects, a heavy crane is unnecessary to stabilize the movement, indicating a lack of weight adjustment mechanisms for the crane. (Summary of the Invention)

[0004] The purpose of this invention is to provide a lightweight, single-beam suspended explosion-proof crane with the advantages of a unified power source and power transmission, reducing its own weight, and preventing excessive wear caused by prolonged heavy operation, thereby solving the problems mentioned in the background art.

[0010] Furthermore, the lifting assembly includes two trapezoidal plates, a rectangular plate, two cranes, a mounting box, a cylinder, a first transmission wheel, a first motor, four driven shafts, two second transmission wheels, and four rollers. The two trapezoidal plates are both mounted on the crossbeam. The rectangular plate is fixedly installed between the two trapezoidal plates.

[0014] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this invention are:

[0015] This invention, by setting up a synchronization component, starts a dual-axis motor, which drives a rotating rod to rotate. The rotating rod rotates on a support plate, which in turn drives a circular plate to rotate. Simultaneously, the circular plate rotates, causing a universal coupling to move in a circular motion. The universal coupling then moves a connecting rod. Through the cooperation of the universal coupling and the connecting rod, power is transmitted upwards from the lower position. The universal coupling drives the circular plate at the higher position to rotate, which in turn drives a circular rod to rotate. The circular rod rotates on a concave plate, and simultaneously drives a gear to rotate. The gear meshes with a gear plate, causing the gear to roll on the gear plate. The circular rod then drives a moving wheel to rotate, causing the moving wheel to roll on a moving rail, thus moving the crossbeam and the lifted item for transportation. This invention has the advantages of a unified power source and power transmission, reduced weight, and prevention of excessive wear caused by prolonged heavy-duty operation.

[0016] This invention, through the setting of adjustment components and counterweight components, causes the fixed frame to move when the crossbeam moves. Simultaneously, the second motor is activated, driving the screw to rotate. The screw's rotation moves the adjustment plate, which in turn moves the vertical plate. The vertical plate then moves the docking rod, aligning it with the interface. Once the crossbeam reaches the appropriate position, it moves the docking rod into the interface. At this point, the second motor reverses, moving the docking rod upwards and lifting the counterweight plate. The counterweight plate then moves the hanging opening from a narrow opening to a wide opening with a diameter larger than the placement rod. The placement rod no longer limits the counterweight plate. The crossbeam then moves in the reverse direction, resetting the fixed frame and docking rod. The crossbeam now carries the weight of the counterweight plate, allowing for self-weight adjustment based on the weight of the lifted object. This design offers advantages such as movable docking, flexible self-weight adjustment according to the lifted item, and prevention of lifting items that are too heavy or too light.

The four rollers 310 are fixedly sleeved on the four driven shafts 308. The rollers 310 are in rolling connection with the crossbeam 101. More specifically, when the hoist 303 is started to lift the item, the motor 307 is started after the item is lifted. The motor 307 drives the transmission wheel 306 to rotate, and the transmission wheel 306 drives the cylinder 305 to rotate.

More specifically, when the crossbeam 101 moves, it drives the fixed frames 401 to move; simultaneously, the movement of the fixed frames 401 activates the second motor 404. Motor 404 drives screw 402 to rotate, which in turn moves adjusting plate 403. Adjusting plate 403 moves vertical plate 405, which in turn moves docking rod 406, aligning it with interface 504. When crossbeam 101 moves to the appropriate position, it moves docking rod 406 into interface 504. At this point, reverse motor 404 moves docking rod 406 upward, lifting counterweight plate 50. 1. The counterweight plate 501 drives the hanging port 503 to move, and the hanging port 503 moves from a narrow opening to a wide opening. The diameter of the wide opening is larger than that of the placement rod 502. At this time, the placement rod 502 no longer limits the counterweight plate 501. The crossbeam 101 moves in the opposite direction and drives the fixed frame 401 and the docking rod 406 to reset. At this time, the crossbeam 101 has the weight of the counterweight plate 501. The self-weight is adjusted according to the weight of the lifted object.

[0037] Working principle:

[0038] Step 1: Synchronous transmission. Start the dual-axis motor 202. The dual-axis motor 202 drives the rotating rod 204 to rotate. The rotating rod 204 rotates on the support plate 203, which in turn drives the circular plate 206 to rotate. Simultaneously, the circular plate 206 drives the universal coupling 207 to rotate in a circular motion. The universal coupling 207 drives the connecting rod 208 to move. Through the cooperation of the universal coupling 207 and the connecting rod 208, the power from the lower position is transmitted upwards. The device 207 drives the circular plate 206 at a higher position to rotate, the circular plate 206 drives the circular rod 211 to rotate, the circular rod 211 rotates on the concave plate 210, and at the same time the circular rod 211 drives the gear 213 to rotate. The gear 213 meshes with the toothed plate 214, so that the gear 213 rolls on the toothed plate 214. The circular rod 211 drives the moving wheel 215 to rotate, so that the moving wheel 215 rolls on the moving rail 212, thereby driving the crossbeam 101 and the lifted object to move and transport.

[0039] Step Two: Moving and Lifting. Start the crane 303 to lift the item. After lifting the item, start the motor 307. The motor 307 drives the transmission wheel 306 to rotate. The transmission wheel 306 drives the cylinder 305 to rotate. While the transmission wheel 306 is rotating, it is driven by the transmission belt, causing the transmission wheel 309 to rotate. The transmission wheel 309 drives the driven shaft 308 to rotate. The driven shaft 308 drives the roller 310 to rotate. The roller 310 rolls on the crossbeam 101 to adjust and move the position of the lifted item.

[0040] Step 3: Adjust the counterweight. When the crossbeam 101 moves, it drives the fixed frame 401 to move as well. Simultaneously, the fixed frame 401 moves, and the second motor 404 starts. The second motor 404 drives the screw 402 to rotate. The screw 402 rotates and drives the adjusting plate 403 to move. The adjusting plate 403 drives the vertical plate 405 to move, and the vertical plate 405 drives the connecting rod 406 to move, aligning the connecting rod 406 with the mating interface 504. When the crossbeam 101 moves to the appropriate position, the crossbeam 101 drives the connecting rod 406 to move into position. Inside the interface 504, the reverse motor 404 drives the docking rod 406 upward, the docking rod 406 moves upward and lifts the counterweight plate 501, the counterweight plate 501 drives the hanging port 503 to move, the hanging port 503 moves from a narrow opening to a wide opening, the diameter of the wide opening is larger than the placement rod 502, at this time the placement rod 502 no longer limits the counterweight plate 501, the crossbeam 101 moves in the opposite direction and drives the fixed frame 401 and the docking rod 406 to reset, at this time the crossbeam 101 has the weight of the counterweight plate 501, the self-weight is adjusted according to the weight of the lifted object.
