Description

Four-lifting-point gantry hook lifting appliance and converter charging crane trolley manufactured by same

Technical Field

The utility model relates to a four hoisting point gantry hook hoists and converter reinforced monkey that makes thereof.

Background

At present, in the charging crane equipment industry, a bridge crane is generally adopted for the charging crane (for example, the date of authorized announcement is 11 and 03 2010, and the number of authorized announcement is CN 201619962U).

As shown in fig. 1, two independent steel wire ropes 2 are arranged on a trolley 1, a fixed pulley block 3 is fixed at the lower end of each steel wire rope 2, one fixed pulley block 3 is connected with a main gantry hook 44, the other fixed pulley block 3 is connected with an auxiliary gantry hook 4, and the main gantry hook 44 and the auxiliary gantry hook 4 are both hooked on a lifting lug 91 of a hopper 9.

As shown in fig. 2, the auxiliary gantry hook 4 is lifted upwards to enable the hopper 9 to start discharging in an inclined mode, and meanwhile, the auxiliary gantry hook 4 is also lifted obliquely outwards, so that the deflection angle of a steel wire rope is too large, the auxiliary gantry hook and the lifting lug 91 are prone to disengaging, the abrasion is serious, and safety accidents are prone to occurring during working.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem who solves: how to design four hoisting point gantry hook hoists, avoid vice gantry hook to draw to hang to one side outward.

The technical scheme of the utility model specifically does:

the utility model provides a four hoisting point gantry hook hoists, includes two movable pulley roof beams, and two movable pulley roof beams link together through the tie-beam, and the movable pulley roof beam is articulated through the round pin axle with the tie-beam, and every round pin epaxial articulated two Long Mengou, and the length of tie-beam between two round pin axles equals with the length of hopper between two lugs, and when the gantry hook was hooked on the lug, tie-beam, two gantry hooks and hopper were parallelogram four-bar linkage structure.

A converter charging crane trolley comprises a trolley frame, wherein a traveling mechanism is arranged at the bottom of the trolley frame, two lifting mechanisms are arranged on the trolley frame, a set of steel wire rope is wound on each lifting mechanism, and the steel wire rope is connected to a movable pulley block on a movable pulley beam of a four-lifting-point gantry hook lifting appliance after bypassing a fixed pulley block of the fixed pulley beam of the four-lifting-point gantry hook lifting appliance.

Compared with the prior art, the technical effect of the utility model is that, the utility model discloses be equipped with parallelogram's hoist, when the hopper begins reinforced, two gantry hooks all keep vertical, reduce the probability that the incident appears.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments thereof.

As shown in fig. 3-5, a four-hoisting-point gantry crane includes two movable pulley beams 21, the two movable pulley beams 21 are connected together through a connecting beam 22, the movable pulley beams 21 are hinged to the connecting beam 22 through pins 24, each pin 24 is hinged to two gantry hooks 23, the length of the connecting beam 22 between the two pins 24 is equal to the length of the hopper 9 between the two lifting lugs 91, and when the gantry hooks 23 are hooked to the lifting lugs 91, the connecting beam 22, the two gantry hooks 23 and the hopper 9 are in a parallelogram four-bar linkage structure.

As shown in fig. 6, a converter charging crane trolley comprises a trolley frame 31, a traveling mechanism 36 is arranged at the bottom of the trolley frame 31, two hoisting mechanisms (such as electric hoists) 33 are arranged on the trolley frame 31, a set of steel wire rope 34 is wound on each hoisting mechanism 33, and the steel wire rope 34 bypasses the fixed pulley block of the fixed pulley beam 32 of the four-hoisting-point gantry hook hanger and then is connected with the movable pulley block 35 on the movable pulley beam 21 of the four-hoisting-point gantry hook hanger.

The working principle is as follows:

as shown in fig. 4-6, when the converter charging crane trolley is lifted correctly, the steel wire rope 34 on the converter charging crane trolley controls the height of the four-lifting-point gantry hook hanger, and the hopper 9 is lifted by the four gantry hooks 23 of the four-lifting-point gantry hook hanger, which is not described in detail.

When charging is needed, one of the steel wire ropes advances upwards to enable the connecting beam 22 to incline, and the connecting beam 22, the two gantry hooks 23 and the hopper 9 are of a parallelogram four-bar linkage structure, so that the hopper 9 is also inclined and charging can be achieved.

In the charging process, because of gravity, the four gantry hooks 23 keep a vertical state, and the probability of safety accidents is reduced.

See the prior art for additional details.

While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
