[0021] Figure 2 The figure is a side view of the hoist of the present application. DETAILED DESCRIPTION

[0022] The technical features of the present application are further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] As shown in the drawings, the present application discloses a large length ultra-high voltage cable wire reel sling, comprising an upper sling ring group 1, a locking device, an open-close hook group, a variable connecting rod, an open-close support component, and an independent hook 3.

[0024] The upper sling ring group 1 has two interlocking sling rings, one of which is connected to the lifting hook of the lifting equipment, and the other is hinged to a connecting component, which has an opening at the lower end for connecting the independent hook 3 and the open-close support component. The structure of the connecting component is shown in the figure.

[0025] One end of the independent hook 3 is a U-shaped hook end, and the other end is hinged to the upper sling ring group 1. The independent hook 3 can be used independently of the open-close hook group and can freely and flexibly lift other objects for cooperation.

[0026] In this application, the open-close hook group includes two open-close hook rods, which are arranged in an X shape. The ends of the two open-close hook rods have oppositely arranged hook portions, which are shaped to cooperate with the special hooking points of the wire reel. The open-close hook group is used to fix the wire reel, and the hook portions closely cooperate with the wire reel jack to fix the wire reel, avoiding rotation and loosening of the wire reel during lifting, which may cause safety hazards. The middle sections of the two open-close hook rods are hinged by a rotating shaft, and the middle sections of the open-close hook rods have obtuse angle bends.

[0027] The open-close support component includes two open-close support rods 4, which are arranged in an inverted V shape, and the two ends of the inverted V shape form two spaced apart connecting ends of the open-close support component.

[0028] The two spaced apart connecting ends of the open-close support component are respectively hinged to the ends of the two open-close hook rods by rotating shaft two, and the other ends of the two open-close support rods 4 have rotating shaft one, which passes through the ends of the two open-close support rods 4 and is rotatably connected to the open-close support rods 4. Rotating shaft one is installed in the lower end opening of the connecting component hinged to the lower part of the upper sling ring group 1 and rotates in the lower end opening of the connecting component.

[0029] Rotating shaft one also passes through the end of independent hook 3 away from the hook end, and independent hook 3 swings through rotating shaft one.

[0030] In the present application, the opening and closing hook group has a locking device for locking the opening and closing angle of the two opening and closing hook rods. The locking device includes a locking disc 502, which is provided with a wrench rod. The surface of the pin shaft 501 has external threads, and the locking disc 502 is an annular disc with an annular inner surface having internal threads. The locking disc 502 is sleeved on one end of the pin shaft 501 and is threadedly connected with the pin shaft 501. The end of the pin shaft 501 away from the locking disc 502 has an expansion part. After the pin shaft 501 passes through the two opening and closing hook rods, the expansion part of the pin shaft 501 is in contact with one of the two opening and closing hook rods.

[0031] To further ensure the fixing strength of the wire coil hoisting, a locking device for locking the opening and closing angle of the two opening and closing hook rods is designed on the opening and closing hook group. In use, the locking device is kept in a locked state, so that the opening and closing angle between the two opening and closing hook rods is fixed and will not fall off due to shaking during hoisting, thereby enhancing the stability and safety of the wire coil hoisting.

[0032] In actual operation, the locking disc 502 is rotated, so that the locking disc 502 and the expansion part of the pin shaft 501 tightly press against the surfaces of the two opening and closing hook rods, and the opening and closing angle of the two opening and closing hook rods is fixed by friction. In actual design, other structures for locking the opening and closing of cross rods in the prior art can be used instead of the above-mentioned structure of the locking device.

[0033] The opening and closing hook rods include variable connecting rods 201 and telescopic hook rods 202. The variable connecting rods 201 of the two opening and closing hook rods are crossed and hinged by the pin shaft 501. One end of the variable connecting rod 201 is hinged to the opening and closing support rod 4, and the other end of the variable connecting rod 201 is provided with an opening. The end of the telescopic hook rod 202 is inserted into the end opening of the variable connecting rod 201.

[0034] The variable connecting rod 201 and the telescopic hook rod 202 are respectively provided with a plurality of fixed pin holes. The fixed pin holes on the variable connecting rod 201 and the fixed pin holes on the telescopic hook rod 202 are arranged in cooperation. The variable connecting rod 201 and the telescopic hook rod 202 have a fixed pin, which passes through one of the fixed pin holes on the variable connecting rod 201 and one of the fixed pin holes on the telescopic hook rod 202.

[0035] The open-close hook rod of the present application is composed of a variable connecting rod 201 and a telescopic hook rod 202, and the cross hook is composed of the variable connecting rod connected with the hanging connecting piece. The variable connecting rod can be adjusted in horizontal width according to the diameter of the wire coil, so as to ensure that the size of the hook can match the diameter of the wire coil, to strengthen the close cooperation of the hook and the wire coil. The cross hook is used for fixing the hoisted wire coil, and the close cooperation of the hook and the wire coil insertion hole can fix the wire coil, to avoid the wire coil from rotating and loosening in the hoisting process, so as to cause safety hazards. When adjusting, the telescopic hook rod 202 is pulled out from the variable connecting rod 201 or is deeply inserted into the variable connecting rod 201, so as to adjust the length of the whole open-close hook rod. After the length is adjusted and one of the fixed pin holes on the variable connecting rod 201 coincides with one of the fixed pin holes on the telescopic hook rod 202, the fixed pin is inserted, so as to fix the length.

[0036] The wire coil hoist of the present application can realize stable hoisting in production and transportation, and can realize quick hanging and detaching due to the design of the hoist special hook and the wire coil special hanging point, to save time and improve labor efficiency, while ensuring the stability of the wire coil and the safety of the surrounding.
