Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Example: Figure 1-4 As shown, this utility model provides a high-strength wind-resistant stabilizing device for a crane, including a crane frame 1. Two self-propelled moving mechanisms 2 are fixedly installed on both sides of the bottom surface of the crane frame 1. Guide rails 3 are installed below each of the two self-propelled moving mechanisms 2. The guide rails 3 cooperate with the self-propelled moving mechanisms 2. Positioning devices 4 are symmetrically installed on one side of each of the two guide rails 3. Each positioning device 4 includes a fixed base 41, and fixing buckles 42 are symmetrically installed on both sides of the top surface of the fixed base 41. Two slide rods 43 are fixedly installed between the buckles 42. Each slide rod 43 is fitted with a sliding sleeve 44. Each sliding sleeve 44 is fixedly installed on the top surface of each sliding sleeve 44. A positioning frame 45 is fixedly installed on one side of the self-propelled moving mechanism 2. A mounting base 5 is symmetrically installed on one side of the mounting base 5. A positioning component 51 is fixedly installed in the middle of one side of the mounting base 5. The positioning frame 45 and the positioning component 51 cooperate with each other. The positioning component 51 includes a positioning element 511. A slot 46 is opened on one side of the positioning frame 45. The positioning element 511 is slidably inserted into the slot 46. The hoisting device is installed using the lifting frame 1. Two guide rails 3 are used in conjunction with the wheels of two self-propelled mobile mechanisms 2. These self-propelled mobile mechanisms 2 are existing technology; a drive mechanism controls the sliding of the wheels within the guide rails 3, controlling the movement of the hoisting device installed on the lifting frame 1 to complete the hoisting work. In windy weather, the self-propelled mobile mechanism 2 moves the crane to the end of the guide rail 3, aligning one side of the self-propelled mobile mechanism 2 with the side of the baffle 31. After alignment, the sliding positioning frame 45 slides with the sliding sleeves 44 installed on the surfaces of the two sliding rods 43. With the cooperation of the slot 46 and the positioning component 511, the positioning frame 45 is positioned on one side of the mounting base 5. The positioning device 4, in conjunction with the corresponding positioning component 51 on one side of the mounting base 5, completes the crane's positioning, increasing the crane's stability and preventing it from sliding back and forth on the guide rails 3 due to wind, thus avoiding safety hazards.

[0014] A bidirectional lead screw 512 is installed in the middle of the inner side of the positioning component 511. Adjusting sleeves 513 are symmetrically sleeved on the surface of the bidirectional lead screw 512. There are two adjusting sleeves 513, which slide relative to each other on the surface of the bidirectional lead screw 512. Guide seats 514 are fixedly installed on one side of each of the two adjusting sleeves 513. There are two guide seats 514. Limiting components 515 are fixedly installed on one side of each of the two guide seats 514. A rotating shaft 517 is installed in the middle of one side of the positioning component 511 located on the bidirectional lead screw 512. A transmission gear 518 is fixedly installed at one end of the rotating shaft 517. A drive gear 516 is fixedly installed in the middle of the surface of the bidirectional lead screw 512. The drive gear 516 meshes with the transmission gear 518. A crank handle 519 is fixedly installed at the end of the rotating shaft 517 away from the transmission gear 518. In the initial state, the two limiting members 515 are hidden inside the positioning member 511. After the positioning frame 45 is installed and positioned on one side of the mounting base 5, the crank handle 519 controls the rotating shaft 517 to drive the transmission gear 518 to rotate. When the transmission gear 518 rotates, the drive gear 516 is controlled to drive the double-acting screw 512 to rotate. When the double-acting screw 512 rotates, the two adjusting sleeves 513 are controlled to drive the corresponding guide seat 514 and the limiting member 515 to slide relative to each other, so that the two limiting members 515 are moved out of the positioning member 511, thus completing the positioning and fixing of the positioning frame 45 on the corresponding side of the mounting base 5.

[0015] A rectangularly distributed positioning pin 52 is fixedly installed on one side of the mounting base 5. A positioning hole 47 is provided on one side of the positioning frame 45. The positioning pin 52 is slidably inserted into the positioning hole 47. With the cooperation of the positioning pin 52 installed on one side of the mounting base 5 and the corresponding positioning hole 47 on one side of the positioning frame 45, the positioning frame 45 is installed and positioned on one side of the mounting base 5. The positioning component 51 is used to increase the firmness and stability of the positioning frame 45 after it is fixed on one side of the mounting base 5.

[0016] Each of the two guide rails 3 has a baffle 31 fixedly installed at one end of its top surface. The baffle 31 cooperates with the self-propelled moving mechanism 2. The baffle 31 installed at one end of the top surface of the two guide rails 3 completes the limitation of the self-propelled moving mechanism 2. When one side of the self-propelled moving mechanism 2 is in contact with one side of the baffle 31, the positioning device 4 and the positioning component 51 are adapted.

[0017] Two bearings 5121 are fitted on both ends of the surface of the bidirectional lead screw 512. The two bearings 5121 cooperate with the bidirectional lead screw 512 to complete the installation and positioning of the bidirectional lead screw 512, and at the same time assist the bidirectional lead screw 512 in rotation.

[0018] A rotating component 5171 is sleeved in the middle of the surface of the rotating shaft 517. The rotating component 5171 is fixedly installed in the middle of one side of the positioning component 511. The rotating component 5171 cooperates with the rotating shaft 517. The rotating component 5171 completes the installation and positioning of the rotating shaft 517 and assists the rotating shaft 517 in rotating.

[0019] Fixing members 411 are symmetrically installed on both sides of the fixing base 41. The fixing members 411 cooperate with the fixing base 41. The fixing base 41 is installed and fixed at a designated position on one side of the guide rail 3 by the fixing members 411 symmetrically installed on both sides of each fixing base 41 and the corresponding bolts.

[0020] Working principle: When encountering windy weather, the self-propelled moving mechanism 2 moves the crane to the end of the guide rail 3, so that one side of the self-propelled moving mechanism 2 is in contact with the side of the baffle 31. After the contact is completed, the sliding positioning frame 45 is slidable with the cooperation of the sliding sleeves 44 installed on the surfaces of the two sliding rods 43. With the cooperation of the slot 46 and the positioning component 511, the positioning frame 45 is positioned on the side of the mounting seat 5. With the cooperation of the positioning device 4 and the positioning component 51 on the corresponding side of the mounting seat 5, the positioning of the crane is completed, which increases the stability of the crane and prevents the crane from sliding back and forth on the guide rail 3 due to the wind, thus avoiding safety hazards. In the initial state, the two limiting members 515 are hidden inside the positioning member 511. After the positioning frame 45 is installed and positioned on the corresponding mounting base 5 side, the crank handle 519 controls the rotating shaft 517 to drive the transmission gear 518 to rotate. When the transmission gear 518 rotates, the drive gear 516 is controlled to drive the double-acting screw 512 to rotate. When the double-acting screw 512 rotates, the two adjusting sleeves 513 are controlled to drive the corresponding guide seat 514 and the limiting member 515 to slide relative to each other, moving the two limiting members 515 out of the positioning member 511, thus completing the positioning and fixing of the positioning frame 45 on the corresponding mounting base 5 side.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
