AI Technical Summary
During the lifting and movement of existing European cranes, the moving plates are prone to collide with the longitudinal beam when they are in the extreme position, resulting in equipment damage and noise.
A European crane including longitudinal beams, transverse beams, moving parts, winding rollers, motors, wire ropes and anti-collision components are designed. The anti-collision assembly consists of a fixed box, a clamping plate, a bump, a damper and a spring. When the moving parts reach the limit position, the movement of the bump and a clamping plate compresses the damper and the spring to relieve the impact potential energy and prevent collision with the longitudinal beam.
Effectively prevents collision between moving parts and longitudinal beams, reduces noise, and keeps the winding roller clean through an automatic cleaning mechanism.

[0002] European-style cranes are known for their high efficiency, space saving and compliance with European standards. European-style cranes usually include single-girder and double-girder cranes, and are widely used in industrial production, warehousing and construction. During the production of some large wind power equipment, due to the heavy tonnage and large size of the parts, European-style cranes are generally used to complete the hoisting and assembly operations of large wind power equipment components.
[0003] However, there are still some problems in the actual use of existing European-style cranes. For example, during the hoisting and moving process of existing European-style cranes, when the moving plate reaches the limit, it is easy to collide with the longitudinal beam. When a collision occurs, on the one hand, it is easy to cause damage to the equipment, and on the other hand, it will generate a large amount of noise. Summary of the Utility Model

[0025] Refer to Figures 1-4 , the utility model provides a technical solution: a European-style crane for the production and assembly of large wind power equipment, including a longitudinal beam 1, a cross beam 2 is arranged on the top surface of the longitudinal beam 1, a moving part 3 is arranged inside the cross beam 2, a winding roller 4 and a motor 5 are fixedly installed on the top surface of the moving part 3, the winding roller 4 and the motor 5 are in transmission connection, a steel wire rope 6 is wound on the outer surface of the winding roller 4, one end of the steel wire rope 6 is provided with a hook 7, and an anti-collision component 8 is arranged on the top surface of the longitudinal beam 1;
[0026] The anti-collision assembly 8 includes a fixed box body 81, which is fixedly installed on the top surface of the longitudinal beam 1. A clamping plate 82 is movably clamped inside the fixed box body 81. A convex block 83 is fixedly installed on one side surface of the clamping plate 82. A damper 85 is fixedly installed inside the fixed box body 81. One end of the damper 85 is fixedly connected to one side surface of the clamping plate 82. A spring 86 is arranged outside the damper 85. One end of the spring 86 is fixedly connected to the inner wall of the fixed box body 81, and the other end of the spring 86 is fixedly connected to one side surface of the clamping plate 82.
[0027] By arranging the anti-collision assembly 8, when the moving part 3 moves to the extreme positions at both left and right ends, it will reach the anti-collision assemblies 8 on both sides. One side surface of the moving part 3 first contacts the protective pad 84. Under the action of inertia, it can push the convex block 83 and the clamping plate 82 to move towards the inside of the fixed box body 81, and compress the damper 85 and the spring 86 to contract. During the contraction process, the potential energy of the impact is released.
[0028] A protective pad 84 is fixedly installed at one end of the convex block 83. The protective pad 84 is a rubber pad. By arranging the protective pad 84, the moving part 3 can be further protected, and the noise generated during impact can be reduced.
[0029] A cavity 87 is separated between one inner wall of the fixed box body 81 and the clamping plate 82. The top surface of the fixed box body 81 is fixedly connected to an air delivery pipe 88. A check valve one 89 is fixedly installed on the outer surface of the air delivery pipe 88. The outer surface of the fixed box body 81 is fixedly connected to an air inlet pipe 811. A check valve two 810 is fixedly installed on the outer surface of the air inlet pipe 811. A C-shaped frame 9 is fixedly installed on the top surface of the moving part 3. A rectangular pipe 12 is fixedly installed on the bottom surface of the C-shaped frame 9. A plurality of air outlet pipes 13 are fixedly connected to the bottom surface of the rectangular pipe 12. Spray nozzles 14 are fixedly installed on the bottom surfaces of the plurality of air outlet pipes 13. A connecting pipe 10 is fixedly connected to the top surface of the rectangular pipe 12. The top end of the connecting pipe 10 is fixedly connected to a double-pass pipe 11. One end of the air delivery pipe 88 is fixedly connected to one end of the double-pass pipe 11.
[0030] When the clamping plate 82 moves towards the inside of the fixed box body 81 under impact, the air inside the cavity 87 can be pressed into the air delivery pipe 88, enter the double-pass pipe 11 through the air delivery pipe 88, and finally enter the rectangular pipe 12 through the connecting pipe 10, and be blown out towards the winding roller 4 through the air outlet pipes 13 and the spray nozzles 14, so as to realize the automatic cleaning of the winding roller 4.
[0031] Specifically, the working process or principle of the European-style crane for the production and assembly of large wind power equipment is as follows: When in use, first hang the large component to be hoisted on the hook 7, then start the control motor 5 to drive the winding roller 4 to rotate, wind the steel wire rope 6, and drive the hook 7 to move upward during the winding process, so as to realize the hoisting of the large wind power equipment parts, and realize the lowering by the reverse rotation of the motor 5;
[0032] During the movement of the moving part 3, it can drive the moving part 3 to move left and right. When the moving part 3 moves to the extreme positions at both left and right ends, it will reach the anti-collision components 8 on both sides. One side surface of the moving part 3 first contacts the protective pad 84. Under the action of inertia, it can push the convex block 83 and the clamping plate 82 to move towards the inside of the fixed box body 81, and compress the damper 85 and the spring 86. During the compression process, the potential energy of the impact is released, thus realizing the purpose of preventing the moving part 3 from directly colliding with the longitudinal beam 1, avoiding the problem that the existing moving part 3 is easily damaged when directly colliding with the double-pass pipe 11, and at the same time reducing the noise during the impact;
[0033] When the clamping plate 82 moves towards the inside of the fixed box body 81 under the impact, it can press the air in the cavity 87 into the inside of the air delivery pipe 88, and enter the inside of the double-pass pipe 11 through the air delivery pipe 88, and finally enter the inside of the rectangular pipe 12 through the connecting pipe 10, and blow out towards the winding roller 4 through the air outlet pipe 13 and the nozzle 14, so as to realize the automatic cleaning of the winding roller 4.
