Description

Technical Field

[0001] The utility model relates to the field of aircraft ground power supply, in particular to a reel machine for retracting and releasing aircraft ground power supply cables with electric and manual switching. Background Art

[0002] When the aircraft ground power supplies power to the aircraft, it is necessary to use a power cable to connect the power supply to the aircraft. The power cable is long and heavy, so a reel is generally used to retract the power cable. The reel is generally driven by a motor to rotate the drum to retract the cable. However, when the circuit fails, the power cable also needs to be retracted in an emergency. At this time, the reel is generally retracted by manually turning the reel. The premise of manual cranking is that the connection between the motor and the reel needs to be disconnected. At present, a mechanical clutch is generally used to connect the motor and the reel. This structure is complex and occupies a large internal space of the reel, resulting in a very large size of the reel. In addition, the failure rate of this mechanical clutch is also high, and regular maintenance is required, which is very inconvenient to use. Utility Model Content

[0003] In order to overcome the deficiencies of the above technologies, the utility model provides a reel for retracting and releasing aircraft ground power supply cables with a fast electric switching hand-cranking mode.

[0004] The technical solution adopted by the utility model to overcome the technical problems is:

[0005] A reel machine for winding and releasing aircraft ground power supply cables with electric and manual switching, comprising a reel machine housing, a reel being arranged inside the housing, a fixed shaft being arranged at one end of the housing, a motor being arranged at the other end, the reel being rotatably mounted on the fixed shaft, the axis of the reel being arranged horizontally in the left-right direction, a reel shaft being coaxially arranged at the other end of the reel, the reel shaft being transmission-connected to the rotating shaft of the motor through a key, and further comprising:

[0006] A hand crank, a connecting shaft is fixed to the front side of the head end, a screw hole I is arranged in the connecting shaft along its axial direction, and a plug column is fixed to the rear side of the tail end;

[0007] The extension handle has a threaded head coaxially arranged at the rear end thereof, and the extension handle is screwed into the screw hole I of the connecting shaft through the threaded head;

[0008] A shaft head is coaxially fixed to the head end of the reel shaft, the longitudinal section of the shaft head is elliptical, and an elliptical hole matching the shaft head is arranged in the plug column along its axial direction; and

[0009] The key-pulling mechanism is arranged on the plug post and is used to pull the key out from between the reel shaft and the rotating shaft of the motor.

[0010] Furthermore, the key pulling mechanism includes a connecting plate installed on the head end of the shaft head in the vertical direction and a circular swivel installed on the head end of the plug column. The bolt passes through the connecting plate and is screwed into the shaft head. The swivel is provided with an L-shaped opening, and the plug column is provided with an opening that intersects with the elliptical hole. When the shaft head is inserted into the elliptical hole of the plug column, the connecting plate is inserted into the opening and the L-shaped opening respectively, and the head end of the extension handle is provided with a hexagonal hole matching the hexagonal head of the bolt.

[0011] In order to fix firmly, it also includes a lifting eye bolt. A through hole II is axially arranged in the plug column, and a screw hole II is axially arranged on the shaft head. When the shaft head is inserted into the elliptical hole of the plug column, the lifting eye bolt passes through the through hole II and is screwed into the screw hole II.

[0012] In order to improve reliability, a side door is rotatably installed at the side end of the reel housing so as to correspond to the position of the shaft head.

[0013] For the sake of aesthetics, a slot is provided at the front end of the reel chassis, and the hand crank is embedded and installed in the slot. A socket corresponding to the connecting shaft is provided in the slot, and the connecting shaft is inserted into the socket.

[0014] In order to improve reliability, a front door is rotatably installed at the front end of the reel housing so as to correspond to the position of the slot.

[0015] In order to fix firmly, a through hole I is provided in the middle of the hand crank, and a screw hole III is provided in the slot. When the hand crank is embedded and installed in the slot, the eye bolt passes through the through hole I and is screwed into the screw hole III.

[0016] The beneficial effect of the utility model is that under normal working conditions, the motor drives the reel to rotate relative to the fixed shaft, thereby reeling in and releasing the cable. When a circuit failure occurs or there is no electricity, the plug of the hand crank handle is connected to the shaft head. Since the shaft head is an elliptical structure, the reel can be rotated by driving the hand crank handle to rotate by the extension handle, so that the cable can be manually reeled in and released, and the reel machine can be quickly switched between the electric mode and the hand crank mode, making the reel machine more convenient to use.

Under normal working conditions, the motor 4 drives the reel 3 to rotate relative to the fixed shaft 7, thereby retracting and releasing the cable. When a circuit failure occurs or there is no electricity, the plug 21 of the hand crank 9 is connected to the shaft head 14. Since the shaft head 14 is an elliptical structure, the reel 3 can be rotated by driving the hand crank 9 to rotate through the extension handle 13, thereby realizing manual cable reeling and fast switching between electric mode and hand crank mode, making the reel machine more convenient to use.

[0028] In one embodiment of the utility model, the key extraction mechanism includes a connecting plate 15 installed at the head end of the shaft head 14 in the vertical direction and a circular swivel 12 rotatably installed at the head end of the plug column 21. The bolt 16 passes through the connecting plate 15 and is screwed into the shaft head 14. The swivel 12 is provided with an L-shaped opening 20, and the plug column 21 is provided with an opening 22 that intersects with the elliptical hole 23. When the shaft head 14 is inserted into the elliptical hole 23 of the plug column 21, the connecting plate 15 is inserted into the opening 22 and the L-shaped opening 20 respectively, and the head end of the extension handle 13 is provided with a hexagonal hole 18 that matches the hexagonal head of the bolt 16. When the key 5 needs to be pulled out, the hexagonal hole 18 of the extension handle 13 is inserted into the bolt head of the bolt 16, and then the bolt 16 can be loosened by turning the hand crank 9. Then, the shaft head 14 is inserted into the elliptical hole 23 of the plug column 21. At this time, the connecting plate 15 is respectively inserted into the opening area of ​​the front and rear directions of the opening 22 and the L-shaped opening 20. Then, the swivel 12 is rotated to rotate the connecting plate 15 to the area in the left and right directions of the L-shaped opening 20, so that the position of the connecting plate 15 and the plug column 21 is locked. By pulling the hand crank 9 outwards, the key 5 can be pulled out using the connecting plate 15. The structure is simple and the operation is convenient.

[0029] In one embodiment of the utility model, an eyebolt 10 is also included. A through hole II 24 is axially arranged in the plug column 21, and a screw hole II is axially arranged on the shaft head 14. When the shaft head 14 is inserted into the elliptical hole 23 of the plug column 21, the eyebolt 10 passes through the through hole II 24 and then screws into the screw hole II. The hand crank 9 is connected and fixed to the shaft head 14 by the eyebolt 10, so that when the hand crank 9 is used to drive the reel 3 to rotate, it can ensure that it is firmly fixed to prevent the plug column 21 from being separated from the shaft head 14.

[0030] In one embodiment of the utility model, a side door 2 is rotatably mounted on the side end of the reel housing 1 in correspondence with the position of the shaft head 14. When the hand crank 9 is used to drive the reel 3 to rotate, the side door 2 is opened to connect the plug 21 with the shaft head 14. When the motor 4 is used to drive the reel 3 to rotate, the side door 2 is closed, which not only improves the aesthetics, but also protects the motor 4 and the shaft head 14, thereby improving the reliability of use.

[0031] In one embodiment of the utility model, a slot 11 is provided at the front end of the reel housing 1, and a hand crank 9 is embedded and installed in the slot 11. A socket corresponding to the connecting shaft 19 is provided in the slot 11, and the connecting shaft 19 is inserted into the socket. When the motor 4 is used to drive the reel 3 to work, that is, when the hand crank 9 is not used, the hand crank 9 can be hidden in the slot 11 as a whole, so as to facilitate its storage. Preferably, a front door 8 is rotatably installed at the front end of the reel housing 1 in a position corresponding to the slot 11. After the hand crank 9 is fixed in the slot 11, the front door 8 is closed, which further improves the aesthetics. When placed, the extension handle 13 can be removed from the head end of the connecting shaft 19, so as to facilitate the insertion of the connecting shaft 19 into the socket and hide and fix it. The extension handle 13 is screwed onto the rear end of the connecting shaft 19.

[0032] In one embodiment of the utility model, a through hole Ⅰ 17 is provided in the middle of the hand crank 9, and a screw hole Ⅲ is provided in the slot 11. When the hand crank 9 is embedded and installed in the slot 11, the eye bolt 10 passes through the through hole Ⅰ 17 and then screws into the screw hole Ⅲ. The eye bolt 10 can more firmly connect the hand crank 9 to the reel housing 1, further improving the reliability of use.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
