Abstract
The invention relates to the technical field of cranes, and provides a crane beam connecting mechanism. The mechanism comprises an end beam and a main beam. The crane connecting mechanism also comprises: a first bush fixedly arranged on the main beam, a second bush fixedly arranged on the end beam, a hinge shaft penetrating the first bush and the second bush, and a separation plate arranged between the first bush and the second bush. An oval slide way is arranged on the second bush. The hinge shaft is restrictedly arranged in the oval slide way. A positioning plate is fixedly arranged on one side of the crane end beam. The end face of the second bush bears against the positioning plate. The end beam of the crane has a certain movement range relative to the main beam, wherein a specific movement length can be determined according to the sliding length of the hinge shaft in the oval slide way. When a rail is uneven, the end beam has a certain adjustment degree, such that a traveling wheel always acts on the rail, and a phenomenon of suddenly increased wheel pressures on other traveling wheels caused by a suspended traveling wheel can be avoided. Therefore, a security risk is eliminated.
Description
Technical field
The invention belongs to the hoisting crane technical field, relate in particular to a kind of crane beam bindiny mechanism.
Background technology
At present, in the framework of hoisting crane, end carriage and girder are fixedly installed togather usually, and road wheel all is installed on girder and the end carriage, and road wheel is walked in orbit.
When the track unfairness, the unsettled state of road wheel on the end carriage may appear, the so instantaneous increase of the pressure of other road wheels meeting, large to the suddenly change of pressure of track, directly workshop steel structure is caused harmful effect, there is huge potential safety hazard.
Summary of the invention
The object of the present invention is to provide a kind of crane beam bindiny mechanism, be intended to solve the weight of slinging when hoisting crane in the prior art when very heavy, manual operation is very difficult again, and not only labour intensity is large, and very dangerous, the problem that is difficult to realize.
The present invention is achieved in that a kind of crane beam bindiny mechanism, and described crane beam comprises crane end carriage and crane girder, and described hoisting crane bindiny mechanism also is provided with:
Be fixedly installed in the first bearing shell on the described crane girder;
Be fixedly installed in the second bearing shell on the described crane end carriage;
The jointed shaft that runs through described the first bearing shell and the second bearing shell is provided with dividing plate between described the first bearing shell and the second bearing shell;
Described the second bearing shell is provided with oval slideway, and described jointed shaft constraint is installed in the described oval slideway;
One side of described crane end carriage is installed with locating plate, and the end face of described the second bearing shell relies on the described locating plate.
In the present invention, crane girder and end carriage are installed together by jointed shaft, the jointed shaft constraint is installed in the oval slideway of the second bearing shell, end carriage just can have certain moving range with respect to girder like this, concrete movable length can be decided according to the sliding length of jointed shaft in oval slideway, when the track unfairness, end carriage can have certain adjustment degree, can be so that road wheel acts in orbit all the time, be unlikely to unsettled and cause the wheel load of other road wheels to increase suddenly, eliminated potential safety hazard.
Description of drawings
Fig. 1 is the structural representation of crane beam provided by the invention bindiny mechanism.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 shows the structural representation of crane beam provided by the invention bindiny mechanism, for convenience of explanation, has only provided part related to the present invention among the figure.
Crane beam provided by the invention comprises crane end carriage 1 and crane girder 2, and described hoisting crane bindiny mechanism is provided with:
Be fixedly installed in the first bearing shell 3 on the described crane girder 2;
Be fixedly installed in the second bearing shell 4 on the described crane end carriage 1;
The jointed shaft 5 that runs through described the first bearing shell 3 and the second bearing shell 4 is provided with dividing plate 6 between described the first bearing shell 3 and the second bearing shell 4;
Described the second bearing shell 4 is provided with oval slideway, and described jointed shaft 5 constraints are installed in the described oval slideway;
One side of described crane end carriage 1 is installed with locating plate 7, and the end face of described the second bearing shell 4 relies on the described locating plate 7.
In the present invention, crane girder and end carriage are installed together by jointed shaft, the jointed shaft constraint is installed in the oval slideway of the second bearing shell, end carriage just can have certain moving range with respect to girder like this, concrete movable length can be decided according to the sliding length of jointed shaft in oval slideway, when the track unfairness, end carriage can have certain adjustment degree, can be so that road wheel acts in orbit all the time, be unlikely to unsettled and cause the wheel load of other road wheels to increase suddenly, eliminated potential safety hazard.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
