Background
The mobile power supply vehicle has the advantages of flexibility in maneuvering, emergency power supply and the like, and is widely applied to emergency power supply of ground equipment. The mobile power supply vehicle adopts cable equipment to supply power to other equipment, and a cable drum is generally configured for cable collection and cable discharge. The locking mode of the cable reel influences the service performance of the cable reel of the emergency power supply vehicle in the working process, and the problems of impact vibration and the like in the transportation process.
As shown in fig. 1, the conventional cable drum locking device mainly comprises a latch connection block 61, a spring 62, a stopper 63, a latch rod 64, and the like. The plug connection block 61 is welded on the cable drum support frame, and the welding position is not adjustable. The latch lever 64 controls locking and unlocking of the locking device by the spring 62. When the locking device is separated, the latch rod 64 is placed in the arc-shaped groove of the limiting block 63. In the state of the prior art locking device for locking the cable drum, the latch rod 64 must be aligned with the locking hole of the drum, thereby increasing the operation intensity of an operator.

In the process of winding and unwinding a single reel of the cable, the reel which does not work is locked, so that the influence of reel shaking on the cable reel is avoided; in the emergency power supply vehicle driving process, the reel is not firmly locked, impact vibration is easy to generate, and meanwhile, the locking device is seriously damaged due to the increase of the shearing force of the reel. The existing cable reel is generally provided with clamping devices or bolts at two sides of the reel to limit the rotation of the reel, and even the cable reel and the supporting seat are directly locked by adopting a binding belt. The locking mode of the clamping devices arranged on the two sides of the reel has the problems of complex structure, large reaction of shearing force on the locking devices and the like; the mode that the bolt structure limits the rotation of the reel neglects the influence of shearing force on the damage of the bolt structure due to the fact that the whole inertia of the cable reel is large after the cable is wound; the ribbon locking mode is easy to loosen, and the structural stability is poor. Therefore, in order to ensure that the cable reel is firmer in the working and transportation processes, the locking structure is simple and practical, the influence of vibration impact and shearing force is reduced, and the cable reel locking device of the mobile power supply vehicle is designed, so that the structure is simple, the operation is fast and convenient, the locking is firm, and the impact damage is reduced.
