Technical Field

The invention relates to the technical field of monorail cranes, in particular to a monorail crane carrying trolley device.

Background

A heavy-duty traveling trolley of a monorail crane is important bearing equipment on a monorail crane locomotive of coal mine auxiliary transportation equipment, is a carrier for conveying all weight of goods by the monorail crane, is equivalent to wheels and a crossbeam of an automobile, and plays an extremely important role on the monorail crane. The monorail crane runs on a monorail, the front part is provided with a machine head component, an operator operates the monorail crane, the middle part is provided with a driving component for providing traction force, and the rear part is provided with a monorail crane beam component which is specially used for hoisting and transporting goods. The key part for bearing between the hanging beam part and the monorail is the monorail crane walking trolley which plays a role in bearing and transporting.

The current monorail crane carrying trolley has two types, one is a simple type with 4 wheels and no guide wheels, and the other is an improved structure, namely a standard type carrying trolley with 8 wheels, wherein 4 are guide wheels and 4 carrying wheels. Although 4 wheels are added to the improved walking trolley, the number of the loaded wheels is only 4, namely the loading capacity is not changed, and only some wheels with side guide are added, so that the problem of poor key loading capacity is not solved all the time, and therefore, the heavy monorail crane walking trolley does not exist domestically and internationally at present. Because the monorail crane track has the up-and-down slope, also has the level turn, so the wheel on the walking dolly simply increases and can not guarantee that whole bear goods gravity, and the structure is complicated moreover, and the degree of difficulty is big. One solution is to use two walking trolleys to lift one lifting point, so as to disperse the stress of the bearing wheel, but the device has large volume, is inconvenient to use in limited space underground, and has cost which is more than one time higher than that of a single walking trolley.

At present, Chinese patent with publication number CN205714275U discloses a monorail crane walking trolley frame, which comprises two main frame plates arranged in parallel, wherein the two main frame plates are connected together through a support plate positioned at the bottom of a reinforcing rib; the middle of each main frame plate is fixedly connected with a reinforcing rib along the vertical direction, wheel guide devices are respectively arranged on the main frame plates and positioned at two sides of the reinforcing rib, and a reinforcing support lug fixedly connected with the main frame plates is arranged above each wheel guide device; each wheel guiding device comprises a seesaw, a spherical sleeve arranged in the seesaw, a rotating shaft penetrating through the spherical sleeve and a vertical shaft penetrating through the seesaw, the spherical sleeve and the rotating shaft in the vertical direction, the outer surface of the spherical sleeve is spherical, and through holes used for installing wheels are respectively arranged on two sides of the vertical shaft on the seesaw.

Although the frame of the trolley of the monorail crane can enhance the bearing capacity of the trolley, can be suitable for a track with curvature and gradient, and can be widely applied to monorail cranes, when the trolley is driven on the track, people can not brake emergently, and accidents are easily caused.
