Abstract
The utility model relates to an ultralow double-beam bridge crane with an electric hoist. The utility model is composed of a bridge frame which comprises a main beam (1) and an end beam (2), a trolley with an electric hoist (7), the electric hoist (7) and a cart traveling mechanism. The trolley is composed of a trolley frame which comprises a cross frame (3) and a longitudinal beam frame (4), trolley wheels (5) and a driving mechanism (6). The utility model is characterized in that the arcuate cross frame in the trolley frame has a concave position at the middle part, and both ends of the cross frame are integrally welded with the longitudinal beam frame, so that the height of the electric hoist can be superposed with the trolley frame, and accordingly, the height H of the entire machine can be reduced. The utility model is especially suitable for occasions which are limited by height, and can also be used in conventional occasions. Compared with the prior art, the utility model has bigger working space.
Description
The utility model relates to a kind of electric block twin beam overhead bridge crane, particularly relates to a kind of ultralow type electric block twin beam overhead bridge crane.
In the prior art, the electric block twin beam overhead bridge crane is equipped with the dolly of winch by crane span structure, and traveling mechanism of the larger traveller and electrical equipment are formed; And by electric block as winch, its structure is the electric block of band in the crane span structure upper edge of traveling mechanism of the larger traveller girder walking, or is configured to the elevator dolly and is positioned at above the double girder bridge.Because the electric block that is configured in above the dolly has occupied certain height, therefore it exists complete machine to take the big shortcoming of vertical dimension, with the 30KN hoisting crane is example, the height H at hoisting crane top is more than 1200 millimeters on the cart rail level, the height H 1 at suspension hook center to hoisting crane top has influenced the utilization of place available space height more than 1420 millimeters.For the mechanical floor in the storehouse on the factory building in some light industrys, the electron trade, airport, shop layer in the comprehensive function building and depot layer, the large-scale high-rise hotel, places such as large and medium-sized freezer, because clear headroom is restricted in them, all can't adopt existing hoisting crane, otherwise it's the end is past crane span structure, the stroke of lifting is too short, can't hang high weight.
The purpose of this utility model is exactly in order to overcome weak point of the prior art, provides a kind of complete machine vertical dimension the end of than, can be used for conventional place, is applicable to the super die bed electric block twin beam overhead bridge crane in short place, the end again.
The purpose of this utility model can realize by following technical measures: it is made up of dolly, electric block and the traveling mechanism of the larger traveller of the crane span structure that comprises girder and end carriage, equipment electric block, dolly is made up of trolley frame, trundle and dolly driver train again, trolley frame then comprises the longeron frame of at least two trundles that across the crossbearer between girder with at the crossbearer two ends the two are connected as a single entity and install, it is characterized in that it is arc that crossbearer in the trolley frame changes straight shape, be that the crossbearer middle part has individual recess downwards, the electric block hole is installed in the recess of crossbearer.The height of electric block is coincided with in the trolley frame, thus the vertical dimension of dwindling complete machine.
The purpose of this utility model can also be further perfect by following technical measures: the cross sectional shape of the arc crossbearer of trolley frame can be " Contraband " font, " I " font, " II " font, " " font, " T " font, and two ends and the welding of dolly longeron frame are connected as a single entity.
The utility model compared with prior art has many advantages: 1, under the identical condition of weight, span, lifting altitude, the working level of lifting, complete machine vertical dimension of the present utility model, the height H 1 that is suspension hook center to hoisting crane top reduces more than 500 millimeters than prior art, girder also reduces more than 500 millimeters to the height H at hoisting crane top, and other main portion size also all reduces to some extent; 2, in light weight, volume is little; 3, can be used for to use the short place of prior art, as mechanical floor in shop layer and depot layer, the large-scale high-rise hotel in: freezer, shorter factory building, airport storehouse, the comprehensive function building etc.; 4, between striding on an equal basis, working space is greater than prior art; 5, use place of the present utility model, can reduce the height of building, thereby reduce its cost; 6, owing to use the interior space of building of the present utility model to reduce, make the place that needs the refrigeration constant temperature and humidity alleviate heat, electric load, reach energy-conservation effect.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the block diagram of a kind of embodiment of the utility model;
Fig. 2 is the front view of a kind of embodiment dolly of the utility model assembly;
Fig. 3 is the cross sectional shape figure of trolley frame crossbearer;
Fig. 4 is the dolly assembly front view of the another kind of embodiment of the utility model;
Fig. 1, Fig. 2 and ultralow type electric block twin beam overhead bridge crane shown in Figure 3 are one of examples of implementation of the present utility model, it is by comprising girder (1), the crane span structure of end carriage (2), comprise crossbearer (3), longeron frame (4), the dolly of trundle (5) and driver train (6), electric block (7) and cart walking mechanism are formed, wherein dolly is in the top of girder, two arc crossbearers of dolly middle part all has individual recess downwards, electric block (7) is installed in the recess of two arc crossbearers (3) of dolly by bolt along the girder direction, the width of crossbearer (3) recess is just become reconciled and can be held an electric block and get final product, the height of recess is near the height of electric block (7), the height of electric block (7) is coincided with in the trolley frame substantially, and crossbearer (3) cross sectional shape is a T shape.
Fig. 1 and ultralow type electric block twin beams double-beam bridge type crane shown in Figure 4 are two of embodiment of the present utility model, the recess of different with the foregoing description the is arc crossbearer (3) of dolly is not straight shape recess, but one fall trapezoidal recess, its oblique angle α is 15 °, the Contraband type that the cross sectional shape of trolley frame crossbearer and longeron frame (4) is equal, Open Side Down for it, crossbearer (3) two ends and longeron frame (4) are welded as a whole, loading is that the vertical dimension H of the utility model complete machine of 30KN only is 910mm, and the H value of prior art is generally 1600mm, and the width between two girders (1) also can reduce because of the vertical installation of electric block (7), so the working space of this product is greater than prior art.
