Description

Portable hoisting trolley capable of being widely used for trolley breast board of sintering machine

Technical Field

The utility model relates to a can wide application in the portable hoist and mount dolly of sintering machine platform truck breast board.

Background

As is well known, the sintering pallet serves as a key device for sintering the sintering ore in the sintering plant in the whole sintering system, and the shutdown is caused once the problem occurs. In 24 hours of repair each month, the grate bars of more than 100 trolleys of the sintering machine are inspected and replaced, and in the process of replacing the grate bars, one step which needs to be carried out is to lift the trolley baffle plates and then carry out the work of inspecting and replacing the grate bars. The traditional construction method is to use a sintering machine crown block to lift a trolley breast board, a sintering machine factory building is generally only provided with two crown blocks and can be constructed in two places at the same time, and under the condition, the replacement of a trolley grate bar generally needs more than ten hours and also occupies the crown block for a long time. And at every turn, the construction is decided to repair, sintering machine aircraft nose, in the machine, tail overhaul project many, personnel concentrate, and various constructions are changed spare part, worker's machines and tools etc. and need use the overhead traveling crane more, use overhead traveling crane hoist and mount platform truck breast board for a long time to carry out the grid section and change and can lead to other overhaul projects to delay seriously, influence the maintenance construction progress to influence sintering output.

SUMMERY OF THE UTILITY MODEL

To the technical problem, an object of the utility model is to provide a can wide application in the portable hoist and mount dolly of sintering machine platform truck breast board.

To this kind of condition, the utility model discloses a but wide application is in the electronic hoisting trolley of portable of sintering machine platform truck breast board utilizes sintering machine I-shaped steel roof beam as hoisting trolley's walking track ingeniously, realizes that many positions dismantle the hoist and mount breast board fast.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a can extensively use in portable hoisting trolley of sintering machine platform truck breast board which characterized in that: the trolley comprises a trolley base, wherein an L-shaped suspension arm is arranged on the trolley base, a winch and a pulley block are arranged on the L-shaped suspension arm, and a steel wire rope of the winch bypasses the pulley block; the trolley base is of a channel steel structure, two rows of steel wheels are respectively arranged on the inner sides of two side plates of the channel steel, and wing plates for clamping I-shaped steel beams of the sintering machine are arranged on the upper portions and the lower portions of the two rows of steel wheels.

Further, at least two steel wheels are arranged in each row.

Further, the winch is arranged in the middle of the vertical rod part of the L-shaped suspension arm.

Furthermore, the pulley block comprises three fixed pulleys which are respectively arranged at the upper part of the vertical rod part of the L-shaped suspension arm and at the two ends of the cross rod part of the L-shaped suspension arm.

Furthermore, a fixed sleeve is arranged on the trolley base, and a plurality of through holes are axially formed in the fixed sleeve; the lower part of the vertical rod part of the L-shaped suspension arm is also provided with a through hole, and the lower part of the vertical rod part is inserted into the fixing sleeve and is fixedly connected with the fixing sleeve through a fixing bolt.

The utility model has the advantages that: the utility model discloses utilize sintering machine I-shaped steel beam as the walking track of hoisting trolley ingeniously, make it can only be along sintering machine I-shaped steel beam track back-and-forth movement under the effect of dolly steel wheel, guaranteed the walking and the stability of making a round trip of this device, mutually support with assembly pulley and hoist simultaneously, guaranteed that this device can make a round trip to change between different platform truck breast boards, realized hoist and mount fast high-efficiently safely. Compared with the traditional construction method using the crown block, the device has the advantages of simple structure, convenience in assembly and disassembly at any time and any place, suitability for various working conditions, strong universality, capability of realizing simultaneous construction of multiple parts, shortened construction period, reduced labor cost, improved production efficiency and great economic benefit.
