Monorail crane heavy walking trolley

Abstract

The invention provides a monorail crane heavy walking trolley.The monorail crane heavy walking trolley comprises two main frame plates arranged in parallel, a reinforcing rib fixedly connected with the main frame plate is arranged in the middle of each main frame plate in the vertical direction, and the two main frame plates are connected through a supporting plate at the bottom of the reinforcing ribs; the two sides of each main frame plate are each provided with a wheel guide device and an axle base, the axle bases are used for installing axial guide wheels in the vertical direction, and reinforcing supporting lugs fixedly connected with the main frame plates are arranged above the wheel guide devices; each wheel guide 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, wherein the outer surface of the spherical sleeve is spherical, and bearing wheels axially perpendicular to the main frame plate face are installed at the two sides of the spherical sleeve on the seesaw respectively.The monorail crane heavy walking trolley is high in bearing capacity, capable of adapting to gradient rails with curves and capable of being widely applied to a monorail crane.

Description

Technical field [0001] The invention belongs to the field of auxiliary transportation in coal mines, and specifically relates to a monorail crane heavy-duty walking trolley. Background technique [0002] The monorail crane heavy-duty walking trolley is an important load-bearing equipment on the monorail crane locomotive, which is the auxiliary transportation equipment of the coal mine. It is the carrier of the total weight of the monorail crane to transport the goods. It is equivalent to the wheels and beams of the car. . The monorail crane runs on a monorail. The front part has a head part and is operated by the operator. There is a driving part in the middle to provide traction. The rear part is a monorail suspension beam part, which is specially used for hoisting and transporting goods. The key component to undertake between the hanging beam component and the monorail is the monorail crane walking trolley, which plays a bearing and transportation role. [0003] There are curre...

AI Technical Summary

Problems solved by technology

Although the improved walking trolley adds 4 wheels, there are only 4 wheels for carrying, that is, the carrying capacity has not changed, but some side-guided wheels have been added, and the key problem of poor carrying capacity has not been solved. Therefore, at present There is no such heavy-duty monorail crane trolley at home and abroad

Since the monorail crane track has up and down slopes and horizontal turns, the simple addition of wheels on the trolley cannot guarantee that all the weight of the goods will be borne, and the structure is complex and difficult

One solution is to use two trolleys to lift a lifting point, so as to disperse the force on the bearing wheels, but the device is bulky, and it is extremely inconvenient to use in a limited space underground, and the cost is also higher than that of a single trolley. times more
