Description

TECHNICAL FIELD

[0002] In the mechanical manufacturing process, hoisting is a link with the highest safety hazard, and a suitable hoisting method and hoisting device can greatly improve hoisting safety, protect the safety of hoisting personnel, and improve production efficiency, thereby saving costs for enterprises.

[0003] Due to the particularity of the drum shape, the drum is not suitable for horizontal placement during transportation, and horizontal placement may cause the drum to roll during transportation, which is risky. Therefore, the drum is more suitable for vertical placement for transfer. The vertically placed drum has problems of hoisting difficulty and overturning difficulty. The common overturning method for the drum is to bind the drum center position with a sling, and to overturn the drum by hoisting to change the drum from a vertical state to a horizontal state. This method has certain safety hazards, and the risk during the overturning process is uncontrollable, and the efficiency is low. The common hoisting method for the drum is hoisting by a sling. Before hoisting by the sling, the center of gravity of the drum needs to be found through multiple trial hoisting, and then the drum can be hoisted horizontally. During the hoisting process, the angle of the drum cannot be adjusted for hole alignment. If it is found that the hole position is not aligned when the drum is assembled, the drum needs to be lowered, the angle of the drum needs to be rotated, and the drum needs to be hoisted again for hole alignment. This method is relatively complicated and has low efficiency. In addition, if the drum has sharp parts, the sling may be damaged, and hoisting safety problems may occur.

[0004] Patent CN 218174399 U is a hoisting and carrying device for large-scale steel casing production, which comprises a hoisting device, a supporting arm, a fixing rod, a hydraulic rod and an adjusting block. The supporting action of the adjusting blocks on the left and right sides keeps the whole carrying device stable and prevents it from shaking. During hoisting, the supporting arm strengthens the support on the inner wall through the supporting action of the hydraulic rod, and then hoists the cylinder body. Since the main hoisting direction is vertical hoisting, the device cannot hoist a horizontally placed cylinder body, and therefore the device is only suitable for hoisting and carrying the cylinder body and cannot be used for hoisting and assembling the cylinder body.

The sling is connected to an electric hoist of a travelling crane in a workshop to realize the hoisting of the wind drum. Since the device can only be used for hoisting a horizontally placed wind drum, it cannot be used for hoisting a vertically placed wind drum. In addition, the device is not connected to the wind drum, and the wind drum may fall off during hoisting, which may cause safety hazards.

The rotating driving member is further connected with the vertical beam of the main hoisting beam (2), and is used to drive the connecting shaft (34) to reciprocating deflect around the axis thereof. ​ ​ ​ ​ ​ ​ The second end of the connecting shaft (34) is fixedly connected with the drum rotating mechanism (4).

7. The drum overturning hoisting device according to claim 6, characterized in that, The overturning driving member comprises a first driving motor, and an output end of the first driving motor is fixedly connected with the connecting shaft (34); or The overturning driving member comprises a first eccentric wheel (33) eccentrically arranged and fixed to an outer circle of the first end of the connecting shaft (34), a first oil cylinder seat (31) fixed to the vertical beam of the main hoisting beam (2), and an overturning oil cylinder (32) telescopically arranged and having two ends connected with the first oil cylinder seat (31) and the first eccentric wheel (33), so that the connecting shaft (34) is driven to reciprocally deflect around its own axis by the first eccentric wheel (33) during the telescopic movement of the overturning oil cylinder (32).

8. The drum overturning hoisting device according to claim 6, characterized in that, The drum rotating mechanism (4) comprises a rotating frame (41) fixed with the second end of the connecting shaft (34), a mounting shaft (44) rotatably arranged in the rotating frame (41), a rotating driving member and a rotating bracket (45) fixedly connected with two ends of the mounting shaft (44); The rotating bracket (45) is arranged to extend into the drum (6) and is used for mounting the drum supporting mechanism (5); The rotating driving member is used for driving the mounting shaft (44) to rotate around its own axis, and then driving the drum (6) to rotate circumferentially through the rotating bracket (45).

9. The drum overturning hoisting device according to claim 8, characterized in that, The rotating driving member comprises a second driving motor, and an output end of the second driving motor is fixedly connected with an end of the mounting shaft (44); or The rotating driving member comprises a second eccentric wheel (43) eccentrically arranged and fixed to an outer circle of the first end of the mounting shaft (44), a second oil cylinder seat (47) fixed to the rotating frame (41), and a rotating oil cylinder (42) telescopically arranged and having two ends respectively connected with the second oil cylinder seat (47) and the second eccentric wheel (43), so that the mounting shaft (44) is driven to rotate around its own axis by the second eccentric wheel (43) during the telescopic movement of the rotating oil cylinder (42).

10. The drum overturning hoisting device according to claim 8, characterized in that, The drum supporting mechanism (5) comprises two groups of supporting oil cylinders (51) telescopically arranged, and supporting blocks (52) connected with telescopic ends of the supporting oil cylinders (51); The two groups of supporting oil cylinders (51) are oppositely arranged in the rotating bracket (45), and the telescopic ends of the supporting oil cylinders (51) are connected with the supporting blocks (52) after extending out of the rotating bracket (45), so that the inner wall surface of the drum (6) is clamped by the supporting blocks (52).
