Description

Technical Field

[0001] This utility model relates to the field of crane technology, and more specifically to an intelligent adaptive stable conveying crane. Background Technology

[0002] Cranes, also known as overhead cranes, gantry cranes, or hoists, are multi-action lifting machines that vertically lift and horizontally move heavy objects within a certain range. They are widely used in various operations such as lifting, transporting, loading and unloading, installing, and transporting personnel, and are indispensable equipment in modern industrial production.

[0003] Inadequacies of existing technology: In operation, existing cranes mostly use a drive device to drive a reel to wind and unwind the traction rope, thereby lifting and lowering the load. However, in actual use, as the number of turns of the traction rope on the reel changes, the length of the traction rope changes with each rotation of the reel. Existing cranes cannot flexibly control the speed of the reel during operation to ensure that the winding and unwinding speed of the traction rope remains constant, which affects the stability during lifting. At the same time, it is impossible to make the traction rope evenly wound on the reel to avoid gaps between the traction ropes during the winding process. Utility Model Content

[0006] Furthermore, the measuring mechanism includes a bracket, the bottom end of which is fixedly connected to the top end of a base plate.

[0007] Furthermore, the detection box is equipped with a sliding resistor, a power supply and a current detection device, and the sliding contact of the sliding resistor is fixedly connected to the bottom end of the connecting rod.

[0008] Furthermore, a movable groove is provided on the side of the rotating rod, and a slider is movably connected to the side of the movable groove. The side of the slider is movably sleeved with the side of the connecting rod.

[0009] Furthermore, the sorting mechanism includes a support frame, the bottom end of which is fixedly connected to the top end of the base plate. A base is fixedly connected to the top end of the support frame. A drive shaft is movably sleeved on the inner side wall of the base. A bidirectional threaded groove is formed on the side of the drive shaft. An mounting block is movably connected to the inner side wall of the base. The bottom end of the mounting block is movably connected to the side of the bidirectional threaded groove. A guide ring is fixedly connected to the top end of the mounting block.

[0010] Furthermore, the bottom end of the mounting block is movably connected to a movable block via a pin, and the side of the movable block is movably connected to the side of the bidirectional threaded groove. The movable block has a rhomboid structure.

[0011] Furthermore, a sliding groove is provided on the inner side wall of the base, and a support wheel is movably sleeved on the side of the mounting block by a pin, with the bottom end of the support wheel movably connected to the bottom end of the sliding groove.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model uses a drive motor to rotate the mounting shaft via a gearbox, which in turn rotates the winding reel. This allows the traction rope on the reel to be wound up and down.

Simultaneously, a measuring mechanism monitors the diameter of the traction rope after it is wound on the reel and sends a signal to the control terminal, causing the gearbox to change speed and thus adjusting the speed of the reel. This keeps the winding and unwinding speed of the reel constant, which helps improve the stability of the crane.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The intelligent adaptive stable conveying crane involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Reference Figures 1 to 8This utility model provides an intelligent adaptive stable conveying crane, including a traction mechanism 1, a sorting mechanism 2, and a measuring mechanism 3. The top end of the traction mechanism 1 is fixedly connected to the bottom end of the sorting mechanism 2, and the bottom end of the measuring mechanism 3 is fixedly connected to the top end of the traction mechanism 1. The traction mechanism 1 includes a base plate 101, a mounting bracket 103 is fixedly connected to the top end of the base plate 101, a mounting shaft 108 is movably sleeved on the side of the mounting bracket 103, a winding reel 102 is fixedly connected to the side of the mounting shaft 108, a traction rope 105 is fixedly connected to the side of the winding reel 102, a brake 106 is fixedly connected to the side of the mounting bracket 103 corresponding to the position of the mounting shaft 108, a drive motor 104 is fixedly connected to the top end of the base plate 101, and a gearbox 110 is fixedly connected to the output shaft of the drive motor 104. The output shaft of the gearbox 110 is fixedly connected to the side of the mounting shaft 108. The traction mechanism 1 is installed at a suitable position on the crane and the traction rope 105 is connected to the hoisting structure through the guide device. During use, the drive motor 104 drives the mounting shaft 108 to rotate after the gearbox 110 changes speed, thereby driving the winding reel 102 to rotate and wind up and down the traction rope 105 on the winding reel 102. During the winding and unwinding process, the sorting mechanism 2 sorts the traction rope 105 so that the traction rope 105 is evenly wound on the surface of the winding reel 102. At the same time, the measuring mechanism 3 detects the diameter of the traction rope 105 after it is wound on the winding reel 102 in real time and sends a signal to the control terminal to make the gearbox 110 change speed, thereby adjusting the rotation speed of the winding reel 102 and keeping the winding and unwinding speed of the winding reel 102 constant.

[0027] The measuring mechanism 3 includes a bracket 306, the bottom of which is fixedly connected to the top of the base plate 101. A connecting shaft 305 is movably sleeved on the top of the bracket 306, and a rotating rod 302 is movably sleeved on the side of the connecting shaft 305. A roller 310 is movably sleeved on the top of the rotating rod 302 via a pin, and the top of the roller 310 is movably connected to the bottom of the winding reel 102. A detection box 301 is fixedly connected to the top of the base plate 101, and a connecting rod 303 is movably connected to the top of the detection box 301. The top of the connecting rod 303 is movably connected to the bottom of the rotating rod 302, and a tension rod is movably connected to the top of the detection box 301 via a pin. Spring 307, the top end of tension spring 307 is movably connected to the bottom end of rotating rod 302 by a pin. Tension spring 307 drives the bottom end of rotating rod 302 downward, causing rotating rod 302 to rotate along rotating rod 302, so that roller 310 is always in close contact with traction rope 105 on the surface of winding reel 102. As winding reel 102 rotates, winding and unwinding reel 102 causes rotating rod 302 to rotate along connecting shaft 305, driving connecting rod 303 to move up and down. The distance of up and down movement of connecting rod 303 is detected by detection box 301 to determine the diameter of traction rope 105 after winding on winding reel 102, and a signal is sent to control terminal.

[0028] The detection box 301 contains a sliding resistor 312, a power supply 311, and a current detection device 308. The sliding contact of the sliding resistor 312 is fixedly connected to the bottom end of the connecting rod 303. The power supply 311, the current detection device 308, and the sliding resistor 312 are connected by wires. The current detection device 308 is connected to the sliding contact of the sliding resistor 312. When the connecting rod 303 moves up and down, the sliding contact of the sliding resistor 312 moves up and down, causing the resistance of the sliding resistor 312 connected to the circuit to change. The current detection device 308 detects the current change in the circuit in real time and sends it to the control terminal to calculate the thickness of the traction rope 105 on the reel 102.

[0029] The rotating rod 302 has a movable groove 304 on its side, and a slider 309 is movably connected to the side of the movable groove 304. The side of the slider 309 is movably sleeved with the side of the connecting rod 303. When the rotating rod 302 rotates, the slider 309 slides along the slider 309 and drives the connecting rod 303 to move up and down, thereby changing the circular trajectory of the rotating rod 302 into an up and down movement trajectory.

[0030] The sorting mechanism 2 includes a support frame 201, the bottom of which is fixedly connected to the top of the base plate 101. A base 203 is fixedly connected to the top of the support frame 201. A drive shaft 205 is movably sleeved on the inner side wall of the base 203. A bidirectional threaded groove 206 is provided on the side of the drive shaft 205. An mounting block 208 is movably connected to the inner side wall of the base 203. The bottom of the mounting block 208 is movably connected to the side of the bidirectional threaded groove 206. A guide ring 202 is fixedly connected to the top of the mounting block 208. The inner side wall of the guide ring 202 is movably connected to the side of the traction rope 105. When the traction rope 105 is wound on the reel 102, the drive shaft 205 rotates, causing the mounting block 208 to slide along the bidirectional threaded groove 206. This causes the mounting block 208 to slide laterally back and forth along the inner wall of the base 203, allowing the guide ring 202 to guide the traction rope 105, thereby ensuring that the traction rope 105 is evenly wound on the surface of the reel 102.

[0031] The bottom end of the mounting block 208 is movably connected to the movable block 210 via a pin. The side of the movable block 210 is movably connected to the side of the bidirectional threaded groove 206. The movable block 210 has a rhomboid structure, and the two ends of the bidirectional threaded groove 206 have arc-shaped structures. When the movable block 210 slides along the bidirectional threaded groove 206 to the two ends of the bidirectional threaded groove 206, it moves along the arc-shaped structure to turn. The rhomboid structure facilitates the movable block 210 to pass through the staggered position of the bidirectional threaded groove 206.

[0032] The base 203 has a groove 204 on its inner side wall. The mounting block 208 has a support wheel 209 movably connected to its side by a pin. The bottom end of the support wheel 209 is movably connected to the bottom end of the groove 204. When the mounting block 208 slides along the inner wall of the base 203, the support wheel 209 is engaged in the groove 204 to prevent the mounting block 208 from falling off. When the mounting block 208 moves laterally, the support wheel 209 rolls along the groove 204, reducing the friction between the mounting block 208 and the base 203 and reducing wear.

[0033] The mounting shaft 108 has a drive gear 107 fixedly sleeved on its side, the mounting bracket 103 has a transmission gear 109 movably sleeved on its side via a pin, and the transmission shaft 205 has a driven gear 207 fixedly sleeved on its side. The side of the driven gear 207 meshes with the side of the transmission gear 109, and the side of the transmission gear 109 meshes with the side of the drive gear 107. The rotation of the mounting shaft 108 drives the drive gear 107 to rotate, and the meshing of the drive gear 107 with the transmission gear 109 drives the transmission gear 109 to rotate. The meshing of the transmission gear 109 with the driven gear 207 drives the transmission shaft 205 to rotate.

[0034] The working principle of this utility model is as follows: The traction mechanism 1 is installed at a suitable position on the crane, and the traction rope 105 passes through the guide ring 202 and is connected to the hoisting structure through the guide device. During use, the drive motor 104 drives the mounting shaft 108 to rotate after the speed is changed by the gearbox 110, thereby driving the winding reel 102 to rotate and winding the traction rope 105 on the winding reel 102. During the winding and unwinding process, the drive gear 107 and the transmission gear 109 mesh with each other to drive the transmission gear 109 to rotate. The transmission gear 109 and the driven gear 207 mesh with each other to drive the transmission shaft 205 to rotate, causing the movable block 210 to slide along the bidirectional threaded groove 206, thereby driving the mounting block 208 to slide laterally back and forth along the inner wall of the base 203, so that the guide ring 202 guides the traction rope 105, thereby making the traction rope 105 evenly wound on the winding reel. On the surface of 102, the tension spring 307 drives the bottom end of the rotating rod 302 downward, causing the rotating rod 302 to rotate along the rotating rod 302, so that the roller 310 is always in close contact with the traction rope 105 on the surface of the winding reel 102. As the winding reel 102 rotates, it winds and unwinds the winding reel 102, causing the rotating rod 302 to rotate along the connecting shaft 305, driving the connecting rod 303 to move up and down, causing the sliding contact of the sliding resistor 312 to move up and down, causing the resistance of the sliding resistor 312 connected to the circuit to change. The current detection device 308 detects the current change in the circuit in real time and sends it to the control terminal, calculates the thickness of the traction rope 105 on the winding reel 102, determines the diameter of the traction rope 105 after winding on the winding reel 102, and sends a signal to the control terminal to cause the gearbox 110 to change speed, thereby adjusting the rotation speed of the winding reel 102 and keeping the winding and unwinding speed of the winding reel 102 constant.
