Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hoisting equipment, in particular to a hoisting equipment for wind power bearing production. BACKGROUND

[0002] In the production and manufacturing process of wind power bearings, hoisting and transferring is an essential link throughout the key processes of turning, grinding, heat treatment, detection, assembly, etc. Currently, the hoisting operation in this field mainly relies on traditional general hoisting equipment such as bridge cranes with chains, hooks or standard lifting devices. Chain rigging is a hoisting equipment composed of high-strength alloy steel chains, main link rings, hooks or other end fittings through professional connection and assembly processes.

[0003] A large-scale hoisting chain rigging with a safety self-checking function is disclosed in Chinese patent document CN112357746B, which includes a chain, a lock, a hanger assembly, a self-checking mechanism, a first connecting mechanism and a second connecting mechanism. The first and second connecting mechanisms are located at both ends of the chain. The top end of the chain is fixedly connected with the hanger assembly through the first connecting mechanism, and the bottom end of the chain is fixed with the lock through the second connecting mechanism. The self-checking mechanism is located on the hanger assembly, and the chain is fixedly connected with the self-checking mechanism through the hanger assembly. The self-checking mechanism includes a tension sensor. When working, the tension sensor can detect the tension and send the detected signal into the central processor for comparison with the preset warning value. When the tension is greater than the warning value, the alarm works to alarm, thereby realizing the self-checking function and avoiding the safety hazard caused by the tension of the chain rigging exceeding its own bearing range, with high safety.

[0004] In the above technical solution, although the tension sensor is used to detect the tension and avoid the safety hazard caused by the tension of the chain rigging exceeding its own bearing range, the tensile stress of the chain gradually decreases during use. When maintaining the chain, the chain links on the chain need to be checked one by one by maintenance personnel. If the chain deforms, it is difficult to find in time, and safety hazards may occur in subsequent use. SUMMARY

[0005] The present application provides a hoisting equipment for wind power bearing production, which aims to solve the problem that maintenance personnel cannot find the deformation of the chain in time in related technologies.

[0007] Its effect lies in: when hoisting bearing, lifting hook is lifted when lifting chain is wound or unwound by winding device, lifting chain is sleeved on the drive table of rotation wheel, lifting chain exerts force on drive table perpendicular to drive table when winding or unwinding, in turn drives drive table to rotate, if lifting chain is deformed, the buckling of lifting chain and drive table will be deviated, lifting chain exerts force on drive table along the radial direction of rotation wheel, makes drive table slide towards the axis of rotation wheel, makes spraying assembly to spray lifting chain to mark lifting chain, to facilitate maintenance personnel to find deformed lifting chain in time;During hoisting, lifting chain pulls slider and rotation wheel to move upwards to compress elastic member, when lifting chain is broken, elastic member pushes slider to slide downwards, makes rotation wheel abut with stop block, rotation wheel no longer rotates, lifting chain is sleeved on drive table, to avoid lifting hook directly falling off from lifting chain, causing bearing or other heavy objects on lifting hook to be damaged.

[0008] Preferably, the spraying assembly comprises a containing groove opened on the driving table, the containing groove is filled with spraying paint, the containing groove is provided with an atomizing nozzle facing the chain, the rotating wheel is provided with a push rod extending into the containing groove and sealingly connected with the containing groove; when the chain link slides along the radial direction of the rotating wheel in the running process, the push rod connected therewith stably slides in the containing groove, the pre-loaded spraying paint in the containing groove is atomized through the push rod sliding in the containing groove, the atomized paint particles are uniformly sprayed on the surface of the chain, the spraying paint is selected from high-visibility eye-catching colors such as red and yellow, in the subsequent hoisting operation process, the operator can intuitively judge whether the chain link has deformation and other abnormal conditions by observing these eye-catching color marks on the surface of the chain, the visual detection method simplifies the detection process, so that the operator can quickly and accurately identify the chain link that needs to be replaced without the tedious manual detection of the chain link by the maintenance personnel as in the traditional method, thereby improving the work efficiency and detection accuracy.

[0009] Preferably, the rotating wheel is provided with a mounting groove along the radial direction thereof, the driving table is slidingly arranged in the mounting groove, the elastic reset member is a spring I, one end of the spring I is connected to the bottom of the mounting groove, and the other end is connected to the driving table; when the driving table slides along the mounting groove towards the axis of the rotating wheel, the spring I inside the driving table is compressed to produce elastic deformation, when the driving table is out of contact with the chain link in the rotating process, the previously compressed spring I releases the stored elastic potential energy to push the driving table to reset to the initial position away from the axis of the rotating wheel. In the process of continuously winding the chain, the chain links maintaining the original shape can be smoothly fitted into the grooves of the driving table, when the rotating wheel starts to rotate, the normal chain links drive the entire rotating wheel to rotate synchronously through the driving action of the driving table, if there are deformed chain links on the chain, these deformed chain links will continue to exert pressure on the driving table during movement, causing the driving table to continue to move towards the axis of the rotating wheel, while driving the push rod to slide in the containing groove, ensuring that the spraying device can continuously and uniformly spray the deformed chain.

[0010] Preferably, the hook comprises a hook body and a hook head, the hook head is installed at the bottom of the hook body, a locking tongue is rotatably arranged on the hook head, a torsion spring is arranged between the locking tongue and the hook head, and a closed space is formed between the locking tongue and the hook head; in order to ensure the safety and stability of the hoisting process during the hoisting operation of the bearing, the operator should select a suitable hoisting rope, firmly bind the hoisting rope at the designated hoisting position of the bearing, push the locking tongue of the hook, and make the closed space formed between the locking tongue and the hook head in an open state; at this time, the hoisting rope that has been bound is put into the open space, and when the hoisting rope is in place, the pushing force on the locking tongue is released, the locking tongue is automatically reset under the elastic restoring force of the internal torsion spring, and a complete closed structure is reformed between the locking tongue and the hook head, which can effectively prevent the hoisting rope from slipping off the hook due to shaking or accidental conditions during the hoisting of the bearing, thereby ensuring the safe and reliable operation of the entire hoisting operation.

[0011] Preferably, the hook body is a hollow structure, and a sliding groove in the up-down direction is formed on the inner wall of the hook body on both sides, and a sliding block is slidably arranged in the sliding groove; during the hoisting operation of the bearing, when the operator tightens the hoisting chain through the winding device, the tension of the hoisting chain will drive the rotating wheel to move upwards, and as the rotating wheel rises, the sliding block connected with the rotating wheel will also slide upwards until the sliding block reaches the inner top of the sliding groove; in this process, the elastic element installed between the sliding block and the fixed seat will be compressed and deformed due to the force, and store a certain elastic potential energy; when the hoisting chain suddenly breaks during the hoisting of the bearing, the sliding block moves downward to drive the rotating wheel to move downward, so that the stop block is inserted into the insertion slot of the rotating shaft, ensuring that even if the hoisting chain is completely broken, due to the timely intervention of the stop block, the hoisting chain and the driving table can still maintain an effective buckling state, and the driving wheel will stop rotating, which can completely avoid the risk of the hook directly falling due to the loss of traction; when only one end of the hoisting chain breaks, although the hook will tilt and be unbalanced to a certain extent, due to the protection of the stop block, the hook can still be firmly held on the hoisting chain and will not completely fall off; at this time, the operator can orderly control the slow unwinding operation of the unbroken hoisting chain on the other side, so that the hoisted bearing can be stably and slowly lowered to the ground, solving the safety hazard of the bearing directly falling from the sky due to the breaking of the hoisting chain during the hoisting operation, causing equipment damage and even personnel injury.

[0012] Preferably, the elastic member is a compression spring, one end of the compression spring is connected to the inner top wall of the hook, and the other end is connected to the top of the sliding block; during the lifting operation, when the hook starts to lift the bearing or other heavy workpieces, the lifting chain gradually tightens under the action of the lifting force, driving the sliding block connected thereto to slowly move upward along the track of the sliding groove; as the lifting height increases, the sliding block continues to rise until the top thereof contacts the inner top of the sliding groove; the stopper block originally in contact with the rotating wheel is disengaged from the rotating wheel, so that the rotating wheel is in a freely rotatable state; if the lifting chain on one side suddenly breaks, the rotating wheel will be displaced downward under the action of gravity and the elastic force of the compression spring due to the unbalanced force, and the compression spring connected thereto resets; the elastic force of the compression spring pushes the sliding block to slide downward along the sliding groove, the sliding block drives the rotating wheel to descend, and then the stopper block is inserted into the slot of the rotating wheel, thereby locking the rotating wheel and effectively preventing the rotating wheel from continuing to rotate, ensuring the safety and reliability of the lifting operation.

[0013] Preferably, the rotating wheel has rotating shafts on the left and right sides, and a rotating groove is formed on the side of the sliding block facing the rotating wheel; the rotating shafts are rotatably arranged in the rotating groove; a plurality of slots are formed in the radial direction of the rotating shafts, and the upper end of the stopper block is matched with the slots; when the rotating wheel descends under the action of gravity, the rotating wheel rotates around its own axis; during the descent of the rotating wheel, the plurality of slots evenly formed on the rotating shafts pass the position of the stopper block in sequence; when any one of the slots contacts the fixedly installed stopper block, the stopper block is immediately inserted into the slot, forming a locking structure, thereby preventing the rotating shaft from continuing to rotate, and achieving the locking of the rotating wheel.

[0014] Preferably, the winding device is provided with two groups and winds the two ends of the chain respectively; the winding device comprises a driving motor and a winding wheel, and the lifting chain is connected to the winding wheel; the driving motor installed on one side of the equipment rotates to drive the winding wheel connected thereto to rotate synchronously; during the rotation of the winding wheel, the lifting chain wound thereon is gradually tightened and wound, and at the same time, the corresponding winding wheel on the other side of the equipment releases the lifting chain of the corresponding length to realize the stable lifting of the bearing connected to the end of the lifting chain; when the descending operation is required, the rotation direction of the driving motor is reversed, and the winding wheel originally wound changes to the unwinding state, and the winding wheel on the other side changes to the winding state, thereby controlling the bearing being lifted to descend.

[0015] Preferably, the bottom of the hook body is provided with a groove, and the top of the hook head is provided with a block, which is rotatably arranged in the groove; when hoisting the bearing or other heavy equipment, the hook head is designed to have a free rotation function, so that the operator can flexibly adjust the angle and direction of the hook head according to the actual needs, and through the rotation of the hook head, the hoisting point of the heavy object can be easily aligned, ensuring that the hoisting process is more accurate, and the operator only needs to rotate the hook head to the appropriate position to hang it on the lifting rope or lifting ring of the heavy object, greatly improving the efficiency and convenience of the hoisting operation.

[0016] Preferably, the top of the lifting hook is provided with two vertical springs II, the upper end of the spring II is provided with a guide ring arranged concentrically with the spring II, and the two ends of the lifting chain pass through the two guide rings respectively; during the hoisting operation of the material, the two symmetrically distributed guide rings can accurately guide the movement track of the lifting chain, on the one hand, the movement direction of the lifting chain can be effectively controlled, so that it always moves along the preset path, and on the other hand, the mutual entanglement or knotting of the lifting chain during movement can be prevented, thereby avoiding the interruption or safety hazards caused by the entanglement of the lifting chain.

[0017] By adopting the above technical scheme, the present application has the following advantages:

[0018] 1. When hoisting the bearing, the bearing is first bundled and hung on the lifting hook, so that one end of the lifting rope of the bundled lifting hook enters the closed space formed between the locking tongue and the hook head, to prevent the bundled lifting rope from sliding off the lifting hook, and the two winding devices are used to wind or unwind the two ends of the lifting chain respectively, so as to drive the lifting hook to rise or fall;

[0019] 2. When the lifting chain is wound or unwound, the lifting chain is buckled on the driving table of the rotating wheel, thereby driving the rotating wheel to rotate, at this time, the force exerted by the lifting chain on the driving table is perpendicular to the sliding direction of the driving table, if the lifting chain deforms, it cannot be buckled on the driving table again, after the lifting chain is stretched, it will be pressed on the driving table and push the driving table to slide along the mounting groove to the center of the rotating wheel shaft, since the driving table is internally provided with an accommodating groove, and the spraying assembly is arranged in the accommodating groove, when the pushing rod on the rotating wheel slides in the accommodating groove, the spraying paint in the accommodating groove will be sprayed on the lifting chain, so that the subsequent maintenance personnel can timely and conveniently find the deformed chain link for replacement, when the deformed lifting chain passes the driving table, the driving table will be reset under the action of the spring I, if the lifting chain continues to be wound and other chain links deform, the deformed chain can still be sprayed;

[0020] 3. When hoisting, the lifting chain pulls the rotating wheel to move upward until the sliding block slides to the top of the sliding groove, at this time, the compression spring is in a compressed state, if the lifting chain breaks during hoisting, the sliding block will slide downward under the thrust of the spring, prompting the stopper to insert into the slot on the rotating shaft, thereby preventing the rotating wheel from rotating, the link sleeve is connected to the rotating wheel, the rotating wheel no longer rotates, and the hook will not descend, at this time, the operator can let the winding device on one side pay off the lifting chain to make the hook gradually descend, and the bearing falls to the ground, avoiding the damage of the bearing or other hoisted objects caused by the direct descent of the hook due to the breaking of the lifting chain during hoisting.

[0042] Working principle:

[0043] When the bearing is hoisted, the bearing is hung on the hook 2 after being bundled, the end of the hoisting rope of the bundled bearing enters the closed space formed between the locking tongue 27 and the hook head 26, avoiding the bundled hoisting rope from falling off the hook 2, and the two winding devices 4 are used to wind or unwind the two ends of the hoisting chain 1, thereby driving the hook 2 to rise or fall; when the hoisting chain 1 is wound or unwound, the chain links of the hoisting chain 1 are buckled on the rotating wheel 3 and drive the rotating wheel 3 to rotate, at this time, the force exerted by the hoisting chain 1 on the driving table 5 is perpendicular to the sliding direction of the driving table 5, if the hoisting chain 1 deforms, the hoisting chain 1 cannot be buckled on the driving table 5 again, after the hoisting chain 1 is stretched, the hoisting chain 1 will press on the driving table 5 and push the driving table 5 to slide along the mounting groove 31 towards the shaft center of the rotating wheel 3, since the driving table 5 is provided with the accommodating groove 61, and the spraying assembly 6 is arranged in the accommodating groove 61, when the pushing rod 32 on the rotating wheel 3 slides in the accommodating groove 61, the spraying paint 62 in the accommodating groove 61 sprays on the hoisting chain 1, so that the subsequent maintenance personnel can timely and conveniently find the deformed chain link, so as to replace the chain link, when the deformed hoisting chain 1 passes the driving table 5, the driving table 5 is reset under the action of the spring, and if other chain links deform when the hoisting chain 1 is continuously wound, the deformed chain can be continuously sprayed; when hoisting, the hoisting chain 1 pulls the rotating wheel 3 to move upwards until the sliding block 21 slides to the top of the sliding groove, at this time, the compression spring is in a compressed state, if the hoisting chain 1 breaks during hoisting, the sliding block 21 slides downward under the thrust of the compression spring, and then the stop block 24 is inserted into the insertion slot on the rotating shaft, thereby preventing the rotating wheel 3 from rotating, at this time, the chain link is sleeved on the rotating wheel 3, the rotating wheel 3 no longer rotates, and the hook 2 does not fall, at this time, the operator can make the winding device 4 on one side unwind the hoisting chain 1, so that the hook 2 gradually falls and the bearing falls to the ground, avoiding the damage of the bearing or other hoisted objects caused by the direct falling of the hook 2 when the hoisting chain 1 breaks during hoisting.

[0044] Although the embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present application, and those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present application.
