DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] The utility model provides Figure 1-4A crane travel mechanism detection device shown includes: a plurality of tracks 1, wherein the plurality of tracks 1 are two tracks 1, a travel mechanism 2 is slidably mounted between the two tracks 1, and the travel mechanism 2 can move horizontally on the two tracks 1 through a driving component;

[0039] Further, both ends of the walking mechanism 2 are provided with anti-collision mechanisms 3, and the anti-collision mechanisms 3 include: a protective plate 31, an airbag assembly 32, a plurality of elastic assemblies 33, a detection assembly 34 and a buzzer 35. The protective plate 31 is in a long strip structure, and the protective plate 31 is arranged on the outer side of the end of the walking mechanism 2. The airbag assembly 32 is arranged on the front of the protective plate 31. The plurality of elastic assemblies 33 are respectively arranged at both ends of the protective plate 31. The airbag assembly 32 and the elastic assembly 33 can perform position protection on the end of the walking mechanism 2. The detection assembly 34 is fixed to the bottom of the protective plate 31. The detection assembly 34 is used for movement monitoring of the walking mechanism 2. The buzzer 35 is fixed to the end of the walking mechanism 2. Through the buzzer 35, it is convenient to perform collision buzzer alarm processing on the end of the walking mechanism 2.

[0040] Specifically, the airbag assembly 32 includes: an airbag body 321, a vent pipe 322, a dustproof tennis ball 323, a sealing sleeve 324 and a connecting rope 345. The airbag body 321 is fixed to the front of the protective plate 31. A push-type switch is arranged in the middle of the front of the protective plate 31. The push-type switch is arranged in the inner cavity of the airbag body 321. The push-type switch and the buzzer 35 are connected through a power supply so that the outside world impacts the airbag body 321, and the impact force is too large to deform the airbag body 321, causing the push-type switch to be impacted. When the buzzer 35 buzzes and alarms, it is convenient to check the walking mechanism 2 in time. The vent pipe 322 is fixedly inserted in the middle of the protective plate 31, and the dustproof tennis ball 323 is fixed to the vent pipe 322. At one end, a dustproof tennis ball 323 is arranged in the inner cavity of the airbag body 321.

The sealing sleeve 324 is sleeved on the other end of the ventilation pipe 322. The connecting rope 345 is fixed between the sealing sleeve 324 and the protective plate 31. The sealing sleeve 324 is in a friction sealing state with the ventilation pipe 322 through the sealing ring. When a major impact occurs to the airbag body 321, the airbag body 321 cannot be deformed, and the gas in the inner cavity of the airbag body 321 will knock the sealing sleeve 324 out through the ventilation pipe 322, so that the airbag body 321 is deflated, which is convenient for protecting the airbag body 321 and preventing the airbag body 321 from being forced to rupture due to a strong impact.

The fixing plate 341 can be slidably connected to the bottom of the walking mechanism 2 to reduce the damage to the movement sensor 343 caused by the impact. The mounting plate 342 is fixed to the bottom of the fixing plate 341 by a plurality of bolts. The movement sensor 343 is fixed to the lower surface of the mounting plate 342. The movement sensor 343 transmits the movement data to the control panel of the crane, so as to quickly judge the operation status of the crane walking mechanism 2 and facilitate the movement detection of the walking mechanism 2.

[0043] Furthermore, a lifting mechanism 4 is installed at the bottom of the traveling mechanism 2, a hook 5 is fixed at the bottom of the lifting mechanism 4, and a gravity sensor 6 is installed between the hook 5 and the lifting mechanism 4.
