Description

Compact bridge crane side end structure convenient to install

Technical Field

The utility model belongs to the technical field of bridge crane (bridge crane for short), more specifically say and relate to a compact bridge crane side end structure convenient to installation.

Background

The bridge crane (namely, the bridge crane) is widely applied to the operation in the factory buildings in the fields of thermal power, hydropower, metallurgy, building and the like due to the advantages of large lifting capacity, high running speed, high working efficiency, convenient transportation and the like. Because the bridge crane is arranged on a longitudinal rail at the top of a wall body of a factory building, and the size of the top surface of the rail from the roof of the factory building is limited (see fig. 1, the mounting height and space of the bridge crane in most factory buildings are designed according to the small-tonnage bridge crane), in order to ensure that the bridge crane can normally run, the end part of the bridge crane must be ensured not to interfere with the corner of the upper part of the factory building, namely, the height of the end part of the bridge crane above the top surface of the rail must be controlled within a certain range, and generally, only the small-tonnage bridge crane can meet the height limitation. However, for a large-tonnage bridge crane, on one hand, the size of the bridge crane is much larger than that of a small-tonnage bridge crane, and on the other hand, the conventional bridge crane side end structure is formed by vertically stacking and height-overlapping a main beam and an end beam (see fig. 3, 4 and 5), which all result in that the conventional end part of the large-tonnage bridge crane is large in height and is easy to interfere with the position of the corner of the upper part of the plant (see fig. 2 in detail). In order to ensure that the large-tonnage bridge crane can be smoothly installed and smoothly operated, one scheme is to reform and move down the original track, the large-scale reformation on the factory building has high cost and troublesome operation, the effective operation height of the bridge crane is greatly reduced, and the scheme has poor practicability; the other scheme can optimize the structure of the traditional end part of the large-tonnage bridge crane and reduce the height of the end part, and has the advantages of simple structure, low cost, easy realization, strong practicability and high popularization value.

The design principle of the utility model is as follows:

the utility model discloses a carry out configuration optimization to large-tonnage bridging crane both sides end, greatly reduced the overall height of bridging crane both sides end, solved because of the limited technical problem who can't install large-tonnage bridging crane of factory building top installation, guaranteed smooth installation and the non-interference operation of large-tonnage bridging crane, avoided the factory building on a large scale and costly transformation, the utility model has the advantages of simple structure, with low costs, easy realization, the practicality is strong, spreading value is high. More specifically, the utility model discloses move in the web plate of girder both sides wing side, form the open structure in the identical side of outline cross section with the end beam, like this alright in opening the mouth with the side of end beam embedding girder wing side, through the bolt with web plate and the inboard curb plate firm in connection of end beam simultaneously. Like this the utility model provides an end beam just with the external girder wing side of nested mode, the girder that has changed in traditional bridge crane both sides end and end beam overlap joint structure from top to bottom, the mounting height of having saved the end beam (for example weight 50t, span 31.5 m's bridge crane can reduce mounting height 500 mm), greatly reduced the total height of bridge crane both sides, solved because of the limited technical problem that can't install large-tonnage bridge crane of factory building top installation, guaranteed smooth installation and the no interference operation of large-tonnage bridge crane.

The utility model has the advantages of as follows:

the utility model discloses greatly reduced the total height of bridge crane both sides, solved because of the limited technical problem who can't install large-tonnage bridge crane of factory building top installation, guaranteed smooth installation and the non-interference operation of large-tonnage bridge crane, avoided the factory building on a large scale and costly transformation, the utility model has the advantages of simple structure, with low costs, easy realization, the practicality is strong, spreading value is high.

Detailed Description

The present invention will be further described with reference to the accompanying drawings:

as shown in figures 7-10, the compact type bridge crane side end structure convenient for installation of the utility model comprises two rows of supporting blocks (8) which are symmetrically fixed at the inner sides of two opposite walls of a factory building (1) and are arranged in the horizontal direction, two rails (2) which are symmetrically laid on the two rows of supporting blocks (8) along the longitudinal direction (the bridge crane longitudinally advances or retreats along the rails (2)), two main beams (3) which are transversely erected on the rails (2), two end beams (4) which are respectively externally hung at two wing sides of the main beams (3) in an embedded mode (the end beams (4) are embedded at two wing sides of the main beams (3), thus saving the installation height of the end beams, greatly reducing the total height of the two side ends of the bridge crane, solving the technical problem that the large-tonnage bridge crane cannot be installed due to limited installation at the top of the factory building, ensuring smooth installation and non-interference operation of the large-tonnage bridge crane, two traveling wheels (5) arranged at the front end and the rear end of the end beam (4) (four groups of traveling wheels (5) move along the two tracks (2) and can drive a bridge crane consisting of the two end beams (4) and the two main beams (3) to move forwards or backwards along the longitudinal direction, so that the smooth operation of the bridge crane is realized; the two wing sides of the main beam (3) are both side opening structures formed after the web plates (3-1) are moved inwards, the side openings are matched with the cross section of the outer contour of the end beam (4) (so that the end beam (4) can be smoothly embedded on the two wing sides of the main beam (3)), and bolt holes are formed in the web plates (3-1) and the side plates on the inner sides of the end beam (4) (after bolts are screwed on, the end beam (4) can be externally connected to the two wing sides of the main beam (3)).

The utility model discloses a concrete in service behavior as follows:

the utility model provides a girder (3) wing side compares with the girder wing side of traditional big bridge crane, is with abdomen riser (3-1) from traditional tradition abdomen riser (3' -1) position internal shift, forms the identical side open structure of outline cross section with end beam (4). When the connecting structure is installed, the end beam (4) is only required to be embedded into the side opening, and then the bolts are screwed up to firmly connect the web plate (3-1) and the side plate on the inner side of the end beam (4). Therefore, the end beam (4) is externally hung on the wing side of the main beam (3) in a nesting mode, the mounting height of the end beam is saved (for example, the mounting height can be reduced by 500mm by a bridge crane with the weight of 50t and the span of 31.5 m), the total height of two side ends of the bridge crane is greatly reduced, the technical problem that a large-tonnage bridge crane cannot be mounted due to limited mounting at the top of a factory building is solved, and the smooth mounting and the interference-free operation of the large-tonnage bridge crane are ensured.
