As shown in fig. 1-4, the embodiment of the application discloses a balance detection device of a tower crane, which comprises a mounting plate 1, a support plate 2, a rotating rod 3, a rotating plate 31, a detection assembly 4, a rubber sheet 5, a fluorescent layer 6, balls 7 and a plumb line 8. The mounting plate 1 is of a rectangular plate-shaped structure, and a connecting groove 11 is formed in the upper surface of the mounting plate 1. The support plate 2 is of a rectangular plate-shaped structure, and the support plate 2 is arranged on the bottom surface of the mounting plate 1. The bottom surface of backup pad 2 has seted up rotary groove 21, has seted up rotation hole 22 on the inner wall in rotary groove 21, and dwang 3 is the round rod form structure, and dwang 3 rotates the setting in rotation hole 22. The rotating plate 31 has a rectangular plate-like structure, and the rotating plate 31 is fixedly arranged on the rotating rod 3.

The lateral wall of backup pad 2 has seted up first spout 32, has seted up second spout 33 on the interior roof of first spout 32, and detection component 4 sets up on backup pad 2 for detect hoist equilibrium, detection component 4 includes first slide bar 41, coupling spring 42 and drive arrangement 43. The first slide bar 41 is of a rectangular rod-shaped structure, the first slide bar 41 is arranged in the first slide groove 32 in a sliding manner, the upper surface of the first slide bar 41 is provided with a placement groove 44, and an inclined surface is arranged on an edge, which is far away from the inner wall of the connecting spring 42 and is intersected with the upper surface of the first slide bar 41, of the placement groove 44. One end of the connecting spring 42 is fixed to the side wall of the first slide bar 41, and the other end of the connecting spring 42 is fixed to the inner wall of the first slide groove 32.

The driving device 43 is disposed on the support plate 2 for driving the first slide bar 41, and the driving device 43 includes a second slide bar 431 and a connecting rope 432. The second slide bar 431 has a rectangular rod-shaped structure, and the second slide bar 431 is slidably disposed in the second chute 33.
