Abstract
Description
Technical Field
[0001] The utility model relates to the field of hoisting, in particular to a wind power hoisting rope winding structure. Background Art
[0002] Hoisting refers to the general term for the setting up and positioning of equipment by a crane or lifting mechanism. During the inspection or maintenance process, various hoisting machines are used to lift equipment, workpieces, tools, materials, etc. to change their position.
[0003] We often encounter equipment installation, transportation, and installation work. Whether it is lifting with a pole or mechanical lifting, we should pay attention to the following points:
[0004] (1) When loading and unloading mobile equipment by rolling method for earthwork construction, the thickness of the rollers should be consistent and the annual length should be 50cm longer than the width of the support. It is strictly forbidden to wear gloves to fill the rollers. When loading and unloading, the slope of the roller edge should not be greater than 20°. The roller track should be flat and solid, with staggered joints. The rolling speed should not be too fast, and a slip rope should be used when necessary.
[0005] (2) During the setting process, if any problems are found, timely measures should be taken and the lifting can be continued after the problems are resolved.
[0006] (3) When using a lifting rod to hoist large tower equipment, multiple winches are operated together. The hoisting speeds of each winch must be roughly the same to ensure that the force on each lifting point on the tower body is roughly uniform to avoid deformation of the tower body due to uneven force.
[0007] (4) When the tower tank is hoisted by the rotation method or the knocking-down method, the hinge arm installed at the bottom of the tower body must be able to resist the horizontal thrust generated during the lifting process. The left and right ropes of the tower body must be firm during the lifting process. When the tower body is rotated to the correct height, it should slowly fall into the foundation to avoid accidents and deformation.
[0008] (5) When installing equipment on a frame or building, its strength and stability must meet the requirements of the installation conditions. After the equipment is set and positioned, it must be connected, tightened or welded according to the requirements of the drawings. It can only be unhooked after it meets the strength and stability requirements of the design. Otherwise, it must be temporarily fixed.
[0009] Before conventional lifting operations, the lifting rope needs to be checked and the pulley block used for lifting needs to be checked and replaced. The replacement of the pulley block is very troublesome, the pulley block has a large weight, and manual setting wastes manpower and working time, which is very inconvenient. In addition, due to the freedom of the pulley block during the lifting process, it may encounter strong winds, causing the center of gravity of the crane to shift, posing a safety risk and making it difficult to carry out lifting. Utility Model Content
[0010] Based on this, the purpose of the utility model is to provide a wind power hoisting rope winding structure to solve the technical problems of rapid replacement of pulleys and stability.
[0011] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wind power lifting rope winding structure, comprising a movable pulley fixing platform and a fixed pulley fixing platform, an electric push rod is arranged in the center of the movable pulley fixing platform, movable pulleys are arranged on the four sides of the electric push rod inside the movable pulley fixing platform, fixed pulleys are arranged on each side inside the fixed pulley fixing platform, the fixed pulley and the movable pulley are connected by a lifting rope, the fixed pulley and the movable pulley are both provided with a hook, one end of the lifting rope is wound around the hook, and the A movable column is arranged at the bottom of the electric push rod inside the movable pulley fixed platform, cavities are opened on all four sides of the movable column, a movable rack is arranged inside the cavity, a small electric push rod is arranged behind the movable rack, the movable rack can be translated in the cavity by the small electric push rod, the movable rack is meshed with a winding column through a gear, a steel cable is wound on the winding column, a movable shaft is arranged inside the movable pulley, one end of the steel cable is connected to the inner side of the movable shaft, and the other end passes through the movable shaft and is connected to the movable pulley fixed platform
[0012] By adopting the above technical solution, when in use, the crane uses a lifting rope to connect the movable pulley below through the four fixed pulleys in the fixed pulley fixing platform, driving the movable pulley fixing platform to move up and down. After lifting the object, there is a movable pulley around the movable pulley fixing platform.
[0013] When the movable pulley needs to be replaced, the electric push rod pulls the pushing shaft to cause the movable column below to move upward, and the movable rack on the side of the movable column drives the winding column to rotate. The winding column causes the steel cable at one end of the movable shaft to shrink, and the shrinkage of the steel cable drives the connected movable shaft to move inward, and the steel cable not connected to one end of the movable shaft moves outward, causing the movable pulley on the movable shaft to fall under the action of its own gravity and slowly fall through the steel cable to carry out the replacement operation, and then return to the original position and perform the reverse operation.
[0014] When a movable pulley needs to be replaced, it is only necessary to control a small electric push rod to move outward to push the movable rack to move outward, and the other small electric push rods that do not need to be replaced are controlled to move inward to pull the movable rack to move inward, and the operation of replacing the movable pulley is repeated.
[0015] The utility model is further configured that fixed shafts are cross-arranged inside the fixed pulley fixing platform, and the fixed pulleys are connected in pairs through the fixed shafts.
[0016] By adopting the above technical solution, the fixed pulley slides more smoothly and has higher stability.
[0017] The utility model is further configured that a driving shaft is arranged below the electric push rod, and one end of the driving shaft is connected to a movable column.
[0018] By adopting the above technical solution, the lower movable column can run more smoothly and easily.
[0019] The utility model is further configured that the fixed pulley and the movable pulley are both provided with hooks at the upper and lower parts.
[0020] By adopting the above technical solution, it is possible to adapt to hoisting operations in various situations and to perform more suitable binding methods according to the shape and size of the hoisted object.
[0021] The utility model is further configured such that the lifting rope passes vertically upward through one side of the fixed pulley.
[0022] By adopting the above technical solution, during hoisting, all lifting ropes are located in the internal space of the fixed platform, which can improve the stability of the hoisting and slow down the aging of the lifting ropes.
[0023] In summary, the utility model mainly has the following beneficial effects:
[0024] 1. The utility model connects the movable pulley below through four fixed pulleys in the fixed pulley fixing platform, thereby driving the movable pulley fixing platform to move up and down. After the object is hoisted, since there is a movable pulley around each of the movable pulley fixing platforms, the overall center of gravity formed by the crane and the hoisted object is always maintained in a stable position, and there is no danger of overturning.
[0025] 2. The utility model can achieve the function of automatically setting and removing the movable pulley at a fixed point through the up and down movement of the electric push rod and the free movement of the internal movable rack, and through the interlocking of the electric push rod and the internal steel cable structure, which is safe and saves manpower and material resources.

DETAILED DESCRIPTION
[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0034] All items mentioned in this utility model can be obtained in the market or through private ordering.
[0035] A wind power hoisting rope winding structure, such as Figure 1-6 As shown, it comprises a movable pulley fixing platform 1 and a fixed pulley fixing platform 7 , an electric push rod 2 is arranged at the center of the movable pulley fixing platform 1 , and movable pulleys 3 are arranged on four sides of the electric push rod 2 inside the movable pulley fixing platform 1 .
[0036] Fixed pulleys 5 are arranged on each surface inside the fixed pulley fixing platform 7 . The fixed pulley 5 is connected to the movable pulley 3 through a lifting rope 4 . Both the fixed pulley 5 and the movable pulley 3 are provided with a hook 6 , and one end of the lifting rope 4 is wound around the hook 6 .
[0037] A movable column 11 is arranged at the bottom of the electric push rod 2 inside the movable pulley fixing platform 1, and cavities 13 are opened on all four sides of the movable column 11. A movable rack 12 is arranged inside the cavity 13, and an electric small push rod 14 is arranged behind the movable rack 12. The movable rack 12 can translate in the cavity 13 through the electric small push rod 14. The movable rack 12 is meshed with a winding column 16 through a gear, and a steel cable 15 is wound on the winding column 16. A movable shaft 9 is arranged inside the movable pulley 3, one end of the steel cable 15 is connected to the inner side of the movable shaft 9, and the other end passes through the movable shaft 9 and is connected to the movable pulley fixing platform 1.
[0038] When in use, the crane uses a lifting rope 4 to connect the movable pulley 3 below through four fixed pulleys 5 in the fixed pulley fixing platform 7. Fixed shafts 8 are cross-arranged inside the fixed pulley 5 fixing platform. The fixed pulleys 5 are connected in pairs through the fixed shafts 8. The fixed pulleys 5 slide more smoothly and have higher stability, driving the movable pulley fixing platform 1 to move up and down. After lifting the object, since there is a movable pulley 3 around the movable pulley fixing platform 1, the overall center of gravity formed by the crane and the lifted object is always maintained in a stable position, and there is no danger of tipping over.
[0039] When the movable pulley 3 needs to be replaced, the electric push rod 2 pulls the pushing shaft 10 to cause the movable column 11 below to move upward, and the movable rack 12 on the side of the movable column 11 drives the winding column 16 to rotate. The winding column 16 causes the steel cable 15 at one end of the movable shaft 9 to shrink. The shrinkage of the steel cable 15 drives the connected movable shaft 9 to move inward, and the steel cable 15 not connected to one end of the movable shaft 9 moves outward, so that the movable pulley 3 on the movable shaft 9 falls under the action of its own gravity and slowly falls through the steel cable 15 for replacement.
[0040] After the replacement operation is completed, the electric push rod 2 pushes the pushing shaft 10 to cause the movable column 11 below to move downward, and the movable rack 12 on the side of the movable column 11 drives the winding column 16 to rotate. The winding column 16 causes the steel cable 15 not connected to one end of the movable shaft 9 to shrink, driving the movable pulley 3 to move upward, and the steel cable 15 not connected to one end of the movable shaft 9 shrinks. The steel cable 15 pulls the movable pulley 3 upward and drives the steel cable 15 at one end of the movable shaft 9 to move outward, driving the movable shaft 9 to move outward, and closes when the movable pulley 3 rises to its original position, completing the replacement of the movable pulley 3.
[0041] In daily use, it is not necessary to replace all the movable pulleys 3 at once. Since the movable column 11 is provided with movable racks 12 on all four sides and a cavity 13 is opened, an electric push rod 14 is provided behind the movable rack 12, and the movable rack 12 can move freely in the cavity 13 through the electric push rod 14. When it is necessary to replace a certain movable pulley 3, it is only necessary to control a certain electric push rod 14 to move outward to push the movable rack 12 to move outward, and the remaining electric push rods 14 that do not need to be replaced are controlled to move inward, pulling the movable rack 12 to move inward, and the movable rack 12 drives the winding column 16 to rotate. The winding column 16 causes the steel cable 15 at one end of the movable shaft 9 to contract. The contraction of the steel cable 15 drives the connected movable shaft 9 to move inward, and the steel cable 15 not connected to one end of the movable shaft 9 moves outward, so that the movable pulley 3 on the movable shaft 9 falls under the action of its own gravity and slowly falls through the steel cable 15 for replacement.
[0042] After the replacement operation is completed, the electric push rod 2 pushes the pushing shaft 10 to cause the movable column 11 below to move downward, and the movable rack 12 on the side of the movable column 11 drives the winding column 16 to rotate. The winding column 16 causes the steel cable 15 not connected to one end of the movable shaft 9 to shrink, driving the movable pulley 3 to move upward, and the steel cable 15 not connected to one end of the movable shaft 9 shrinks. The steel cable 15 pulls the movable pulley 3 upward and drives the steel cable 15 at one end of the movable shaft 9 to move outward, driving the movable shaft 9 to move outward, and closes when the movable pulley 3 rises to its original position, completing the replacement of a movable pulley 3.
