In the scheme, the hanging pin is inserted into the mounting hole in the motor end cover, and the motor end cover is blocked by the blocking unit and then lifted. The utility model discloses change the couple of traditional hoist into straight rod-like hanging round pin, it passes the less or longer through-hole of hole length in aperture on the motor end cover of being convenient for to add the fender position unit of open-close type and prevent that the work piece from dropping, this hoist simple structure convenient to use lifts by crane the in-process work piece and can not drop safe and reliable.

Description

Motor end cover lifting appliance

Technical Field

The invention relates to the technical field of hoisting, in particular to a motor end cover hoisting tool.

Background

At present, in the assembly of a large motor, disc parts such as end covers and the like have heavier weight and need to be hoisted by a hoisting tool for assembly, and a common hook-shaped hoisting tool is easy to block due to structural interference on the parts and cannot penetrate through a position to be hung, for example, the disc parts such as the motor end covers and the like have flat structures and do not have proper hanging positions. Only the mounting hole on the motor end cover can be used as a direct hoisting position, and the hook-shaped lifting appliance cannot penetrate through the mounting hole due to the fact that the diameter of the mounting hole is smaller and the length of the mounting hole is longer.

When the hook-shaped lifting appliance is used for hanging the motor end cover in the prior art, other auxiliary tools such as lifting ropes need to be used, the preparation work for lifting is complex, and workpieces easily fall off from the lifting appliance, are damaged and cause casualties.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a can lift by crane motor end cover hoist of motor end cover safely.

In order to achieve the above object, the utility model adopts the following technical scheme: a lifting hook or a ring is arranged at the upper end of a lifting rod, a hanging pin is transversely arranged at the lower end of the lifting rod, and a gear unit for blocking a workpiece on the hanging pin from falling off is arranged at the suspension end of the hanging pin.

In the scheme, the hanging pin is inserted into the mounting hole in the motor end cover, and the motor end cover is blocked by the blocking unit and then lifted. The utility model discloses change the couple of traditional hoist into straight rod-like hanging round pin, it passes the less or longer through-hole of hole length in aperture on the motor end cover of being convenient for to add the fender position unit of open-close type and prevent that the work piece from dropping, this hoist simple structure convenient to use lifts by crane the in-process work piece and can not drop safe and reliable.

Detailed Description

A lifting hook or a ring 11 is arranged at the upper end of a suspension rod 10, a suspension pin 20 is transversely arranged at the lower end of the suspension rod 10, and a gear unit for blocking a workpiece A on the suspension pin 20 from falling off is arranged at the suspension end of the suspension pin 20.

The utility model is suitable for a lifting by crane of various work piece A that have the installation through-hole, among the above-mentioned scheme, the shaft diameter that adopts different peg 20 corresponds different mounting hole apertures, and peg 20 length is greater than the logical length of mounting hole, is convenient for like this to pass the mounting hole on the motor end cover with the peg completely, closes gear unit again and lifts by crane work piece A, because there is work piece A that keeps off the gear unit can not drop. The utility model discloses change the couple of traditional hoist into straight rod-like hanging round pin 20, be convenient for it passes work piece A and goes up the less or longer through-hole of hole length in aperture to add open-close type fender position unit and can prevent when being convenient for hang the round pin plug that work piece A from dropping, this hoist simple structure convenient to use lifts by crane in-process work piece A and can not drop safe and reliable.

The gear unit comprises a swing type stop lever 30 hinged on the suspension rod 10, the axial core direction of a hinged shaft 31 of the swing type stop lever is parallel to the axial core direction of the hanging pin 20, and the lever length direction of the swing type stop lever 30 is perpendicular to the length direction of the hanging pin 20. Thus, the opening and closing of the gear unit are realized through the swinging of the swinging type stop lever 30, when the swinging type stop lever 30 swings to be in contact with the hanging pin 20, the closed state of the gear unit is obtained, at the moment, the workpiece A is blocked by the swinging type stop lever 30 and cannot fall off from the hanging pin 20, when the hanging pin 20 needs to be inserted into or pulled out of the mounting hole of the workpiece A, the swinging type stop lever 30 is swung to be in an avoiding position,

the hanging end of the hanging pin 20 is a necking shaft section 21, the lower part of the swing type stop lever 30 is provided with a notch 32 with the opening direction vertical to the lever length direction, and when the swing type stop lever 30 swings to a low position, the notch on the swing type stop lever is clamped on the necking shaft section 21. Because the mass of the workpiece A is large, when the swing type stop lever 30 swings to a low position, if the lower end of the swing type stop lever is not provided with a limit position, the workpiece A is easy to be skimmed, folded and swung, and the swing type stop lever 30 falls off, so that potential safety hazard exists.

The hanger rod 10 is a folding rod formed by an upper segment vertical rod, a lower segment vertical rod and a middle segment cross rod, and the length of the hanging pin 20 is greater than that of the middle segment cross rod of the hanger rod 10. The upper and lower sections of vertical rods of the suspension rod 10 are staggered in order that the hanging pin 20 is approximately positioned on the extension line of the upper section of vertical rod, so that the gravity center of the workpiece A is positioned near the extension line of the upper section of vertical rod, and when the workpiece A is lifted, the vertical rod of the lifting appliance is positioned in the vertical direction, so that the hanging pin 20 is horizontal, the workpiece A is not easy to slide on the hanging pin to extrude the gear unit, and the safety is improved.
