Abstract
Description
Technical Field
[0001] This invention relates to the field of crane technology, and in particular to a general-purpose bridge crane with anti-collision warning function. Background Technology
[0002] A bridge crane is a heavy-duty engineering machine that spans across a workshop, warehouse, or open-air storage yard. It moves longitudinally along tracks on both sides of the bridge via a traveling mechanism, while a trolley moves laterally along tracks on the bridge to achieve three-dimensional spatial transport of heavy objects. During operation, when the crane lifts the goods to the target position and begins to lower them, the goods generally exhibit slight back-and-forth swaying. If the swaying goods are lowered directly, they are prone to colliding with surrounding equipment, workpieces, supports, or building structures. This can lead to minor damage such as broken goods or loss of workpiece precision, or more serious accidents such as equipment failure, structural damage, or even personal injury. In addition, to avoid collisions, operators need to repeatedly adjust the lifting and traveling mechanisms to eliminate swaying, which prolongs the single operation time and reduces overall production efficiency.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example
[0026] Reference Figures 1-5This is the first embodiment of the present invention. This embodiment provides a general-purpose bridge crane with anti-collision warning function. The general-purpose bridge crane with anti-collision warning function includes a main body component 1, including a moving mechanism 11. The moving mechanism 11 includes a drive motor. A roller is provided on the output shaft of the drive motor for driving the drive motor to move. A winch 12 is provided below the moving mechanism 11. A hook 13 is provided at the bottom of the winch 12. The hook 13 is used to suspend the goods. The winch 12 drives the hook 13 to move up and down, and the moving mechanism 11 drives the winch 12 to move, thereby transferring the goods. This is the prior art. This solution will not be described in detail here, and those skilled in the art can clearly understand the working principle.
[0027] Auxiliary component 2 is located at the bottom of the moving mechanism 11 and includes a moving part 21. The moving part 21 includes a support frame 211 fixed to the bottom of the moving mechanism 11. The support frame 211 is connected and fixed to the bottom of the moving mechanism 11 through a cross-shaped card plate. A fixing plate 212 is fixed to the top of the winch 12.
[0028] The top of the fixed plate 212 is fixed with a slide rail 213. There are four slide rails 213, which are rectangular and fixed to the top of the fixed plate 212. The bottom of the support frame 211 is inserted with a support block 214. There are four support blocks 214, which are located on the four sides of the bottom of the support frame 211. There are two rotating columns 215 inside the support blocks 214, which are arranged in an upper and lower cross shape.
[0029] A pulley 216 is provided inside the slide rail 213. A movable block 217 is sleeved on the outside of the pulley 216. There are four movable blocks 217 and four pulleys 216, which are located in the four slide rails 213 respectively. A rotating sleeve 218 is provided inside the movable block 217. The rotating sleeve 218 is rotatably connected to the movable block 217 through a bearing. A fixed shaft 219 is fixed inside the rotating sleeve 218. A spiral groove 215-1 is opened on the rotating column 215. Both ends of the rotating column 215 have spiral grooves 215-1. The two spiral grooves 215-1 are arranged in the same direction. The fixed shaft 219 slides in the spiral groove 215-1.
[0030] The two rotating columns 215 are longitudinal and transverse, respectively. When the goods swing longitudinally, the longitudinal rotating column 215 will rotate. At this time, the fixed shaft 219 will slide in the spiral groove 215-1. Through the cooperation of the two, the movable block 217 and the pulley 216 will move, so that the pulley 216 moves in the direction of the goods swing and pushes the slide rail 213 and the fixed plate 212 to move longitudinally. This causes the fixed plate 212 to drive the winch 12 to move in the direction of the goods swing, thereby moving the winch 12 to a state where it is in the same straight line as the goods. At this time, the force of the goods swinging in the opposite direction will disappear and the swing will stop, thus avoiding the goods from colliding with the surrounding equipment. Moreover, the operator does not need to repeatedly adjust the moving mechanism, reducing the time of a single operation and improving the overall work efficiency.
[0031] If the goods are swinging laterally, then similarly, the lateral rotating column 215 will drive the winch 12 to move laterally in the direction of the goods' swing. Example
[0032] Reference Figure 3 , Figure 4 and Figure 6 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0033] Specifically, a motor 210 is fixed at the bottom of the support frame 211. The motor 210 is a forward and reverse motor. The output shaft of the motor 210 is fixed to the rotating column 215. There are two motors 210, which are connected to the two rotating columns 215 respectively and are used to drive the rotating columns 215 to rotate.
[0034] Specifically, the auxiliary component 2 also includes a buffer 22, which includes a buffer pad 221 fixed inside the support frame 211. A pressure plate 222 is provided on the top of the buffer pad 221. The top of the support block 214 is fixed to the pressure plate 222. When the winch 12 lifts the goods upward, the fixed plate 212 will be pulled downward by the goods and drive the support block 214 to move downward, so that the support block 214 drives the pressure plate 222 to squeeze the buffer pad 221. At this time, the buffer pad 221 is deformed by the force, which can buffer the pulling force on the winch 12. In addition, it can also buffer the vibration of the winch 12 during the movement. Example
[0035] Reference Figure 1 , Figure 2 and Figure 7 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0036] Specifically, the auxiliary component 2 also includes a connector 23, which includes a plate 231 inserted into the movable block 217. The rotating sleeve 218 has a slot 218-1. The plate 231 and the slot 218-1 cooperate. When the plate 231 and the slot 218-1 are engaged, the two will limit the rotating sleeve 218 through their cooperation. When the rotating column 215 rotates, the rotating sleeve 218 will not rotate with the rotating column 215, but will move axially outside the rotating column 215.
[0037] A first spring 237 is sleeved on the outside of the rotating column 215. The two ends of the first spring 237 are fixed to the movable block 217 and the support block 214 respectively. When the movable block 217 moves, it will apply pressure or tension to the first spring 237.
[0038] When the insert plate 231 separates from the slot 218-1, the restriction on the rotating sleeve 218 is released. At this time, the rotating sleeve 218 can rotate and move freely outside the rotating column 215, and the first spring 237 will apply a reset force to the movable block 217, causing it to move the fixed plate 212 and the winch 12 to the initial position. This will reset the fixed plate 212 and the winch 12, and prevent the movement stroke from being too short when they are too close to the side in the next use.
[0039] The top of the movable block 217 is fixed with a positioning frame 232, and the insert plate 231 is movably connected to the positioning frame 232.
[0040] Specifically, there are multiple slots 218-1, which are evenly distributed in a ring on the outside of the rotating sleeve 218. With the setting of multiple slots 218-1, the insert plate 231 can be inserted into the slot 218-1 when the rotating sleeve 218 is rotated to any angle.
[0041] Specifically, a support rod 233 is fixed to the top of the movable block 217. A rotating rod 234 is rotatably connected to the support rod 233 via a rotating shaft. The center of the rotating rod 234 is rotatably connected to the support rod 233 via a rotating shaft. The rotating rod 234 is L-shaped and its top end contacts the support frame 211. A positioning shaft 231-1 is fixed to the top of the insert plate 231. A sliding groove 234-1 is provided on the rotating rod 234. The positioning shaft 231-1 is movably connected to the sliding groove 234-1.
[0042] When the winch 12 is not lifting any goods, the top of the rotating rod 234 will contact the support frame 211 and rotate downward under the reverse thrust of the support frame 211. At this time, the other end of the rotating rod 234 will drive the insert plate 231 to move upward through the cooperation of the positioning shaft 231-1 and the slide groove 234-1, thereby allowing the insert plate 231 to separate from the slot 218-1.
[0043] Specifically, a fixing block 235 is fixed on one side of both the insert plate 231 and the positioning frame 232, and a second spring 236 is fixed between the two fixing blocks 235.
[0044] When the winch 12 lifts the goods, causing the fixed plate 212 to move downward, the rotating rod 234 will separate from the bottom of the support frame 211. At this time, the second spring 236 will push the fixed block 235 and the insert plate 231 downward, so that the insert plate 231 can be inserted into the slot 218-1.
[0045] Therefore, when the winch 12 lifts the goods, the rotation of the rotating column 215 will drive the fixed plate 212 to move. When the winch 12 lowers the goods, the fixed plate 212 can be reset under the elastic force of the first spring 237, without the need to control the rotating column 215 to rotate in the opposite direction.
[0046] A fixing rod 24 is fixed to the bottom of the fixing plate 212. A sensor 25 is fixed to one side of the bottom of the fixing rod 24. There are four fixing rods 24 and four sensors 25, which are fixed to the four sides of the bottom of the fixing plate 212, in two directions, and are connected to motors 210 in two directions respectively. The sensor 25 is only powered on when the goods are put down. The sensor 25 is a laser displacement sensor, which can accurately detect the swing direction and swing angle of the wire rope.
[0047] The sensor 25 senses the swing direction of the wire rope on the winch 12. If the wire rope is swinging laterally and to the right in the lateral direction, the sensor 25 will start the motor 210 in the lateral direction to rotate a specified number of times according to the swing stroke of the wire rope. Then, the motor 210 can drive the rotating column 215 to rotate. At this time, the movable block 217 will drive the fixed plate 212 to move to the right.
[0048] If the wire rope swings to the left, the motor 210 will rotate in the opposite direction, causing the movable block 217 to move the fixed plate 212 to the left. Therefore, when the goods are put down, the fixed plate 212 will move to the corresponding position depending on which direction the wire rope swings.
[0049] The main component 1 also includes a support rail 14, on which the moving mechanism 11 slides.
[0050] When in use, when the winch 12 lifts the goods upward, the fixed plate 212 will be pulled downward by the goods, and will drive the support block 214 to move downward, so that the support block 214 drives the pressure plate 222 to squeeze the buffer pad 221. At the same time, the rotating rod 234 will separate from the bottom of the support frame 211, and the second spring 236 will push the fixed block 235 and the insert plate 231 to move downward, so that the insert plate 231 is inserted into the slot 218-1. Through the cooperation of the two, the rotating sleeve 218 will be limited, so that when the rotating column 215 rotates, the rotating sleeve 218 will not rotate with the rotating column 215.
[0051] When the goods are moved to the designated position, the sensor 25 is powered on and senses the swing direction of the wire rope on the winch 12. If the wire rope is swinging laterally and to the right in the lateral direction, the sensor 25 will start the motor 210 in the lateral direction to rotate a specified number of times according to the swing stroke of the wire rope. Then the motor 210 can drive the rotating column 215 to rotate.
[0052] When the rotating column 215 rotates, the fixed shaft 219 slides in the spiral groove 215-1. Through the cooperation of the two, the movable block 217 and the pulley 216 move, causing the pulley 216 to move in the direction of the swing of the goods, and pushing the slide rail 213 and the fixed plate 212 to move longitudinally. This causes the fixed plate 212 to drive the winch 12 to move in the direction of the swing of the goods, thereby moving the winch 12 to a state where it is in the same straight line as the goods. At this time, the force of the goods swinging in the opposite direction will disappear and the swing will stop, thus avoiding the goods from colliding with the surrounding equipment. Moreover, it eliminates the need for staff to repeatedly adjust the moving mechanism, reduces the time of a single operation, and improves the overall work efficiency.
[0053] If the wire rope swings to the left, the motor 210 will rotate in the opposite direction, causing the movable block 217 to move the fixed plate 212 to the left. Therefore, when the goods are put down, the fixed plate 212 will move to the corresponding position depending on which direction the wire rope swings.
[0054] When the winch 12 lowers the goods, the buffer pad 221 will apply an upward thrust to the pressure plate 222. The pressure plate 222 will drive the support block 214 and the fixed plate 212 to move upward. At this time, the top of the rotating rod 234 will contact the support frame 211 and rotate downward under the reverse thrust of the support frame 211. At this time, the other end of the rotating rod 234 will drive the insert plate 231 to move upward through the cooperation of the positioning shaft 231-1 and the slide groove 234-1, so that the insert plate 231 can be separated from the slot 218-1.
[0055] When the insert plate 231 separates from the slot 218-1, the restriction on the rotating sleeve 218 is released. At this time, the rotating sleeve 218 can rotate and move freely outside the rotating column 215, and the first spring 237 will apply a reset force to the movable block 217, causing it to move the fixed plate 212 and the winch 12 to the initial position. This will reset the fixed plate 212 and the winch 12, and prevent the movement stroke from being too short when they are too close to the side in the next use.
[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
