Abstract
The utility model discloses a crane beam. The crane beam comprises two main beams which are parallel to each other, wherein the two ends of the two main beam are respectively provided with an end beam; a rectangular notch is formed in the tip of each main beam, near the lower part; the corresponding tip of the corresponding end beam is dovetailed to and clamped inside the corresponding notch; both the two end beams are connected with the two main beams through hinged shafts; each rectangular notch of each main beam is internally and fixedly provided with fixed plates which are respectively positioned at the two sides of the corresponding end beam; the two ends of the corresponding hinged shaft are fixedly arranged on the corresponding fixed plates in a penetration way; and the middle part of each hinged shaft penetrates through the corresponding end beam and is rotatably matched with the end beam. The main beams are movably connected with the end beams through the hinged shafts, the four connection parts of the main beams and the end beams are not completely positioned on the same plane and can be staggered vertically, so that free adjustment can be implemented when the ground is not flat, and the problem of driving wheel elevating cannot occur; and all the wheels of a crane are in contact with the ground, and therefore, the crane is prevented from being twisted and running off rails.
Description
Technical field
The utility model relates to a kind of crane beam, relates in particular to a kind of beam of double girder crane.
Background technology
Double girder crane has two girders, two girders are parallel to each other, be respectively arranged with a heel end beam at the two ends of two girders, two butt beams are joined together to form two girders the integral body of a frame shape, as shown in Figure 1, offer rectangular indentation in the position of the close bottom of the termination of girder 1, rectangular indentation is that girder is cut away formation near the angle of bottom, the corresponding termination of corresponding end carriage 2 coincide and is fastened in the cooresponding rectangular indentation, and girder 1 and end carriage 2 are in the same place by bolt.When hoisting crane moved in orbit, this crane beam was without any problem, but in a few thing occasion, the place is to rent, and the lessor does not allow to lay on the ground track, so just can only set up guiding aloft.In use, some cement flooring is uneven, because girder and end carriage are rigidly connected, it is built on stilts driving wheel to occur, and hoisting crane is turned round strength, run and tiltedly cause damage to getting on the right track, even derailing causes the accident, and causes very big loss to the user.
The utility model content
The purpose of this utility model provides a kind of crane beam, to solve in the prior art because girder and end carriage be rigidly fix and driving wheel that the hoisting crane that causes occurs when move on uneven ground is maked somebody a mere figurehead, hoisting crane is turned round the problem of strength even derailing.
In order to realize above purpose, the utility model adopts following technical scheme: a kind of crane beam, comprise two girders that are parallel to each other, be respectively arranged with an end carriage at the two ends of two girders, position in the girder termination near the bottom offers rectangular indentation, the corresponding termination of corresponding end carriage coincide and is fastened in the cooresponding rectangular indentation, two end carriages all are connected with two girders by hinge, each rectangular indentation internal fixation of each girder is provided with the adapter plate of the both sides that are in end carriage respectively, the two ends of cooresponding hinge fixedly are located on the cooresponding adapter plate, the middle part of hinge pass end carriage and with the end carriage normal-running fit.
The both sides of described end carriage are provided with brace panel in the stationkeeping that cooperates with hinge, have the through hole that passes for hinge on the brace panel.
Flexibly connect by hinge between girder of the present utility model and the end carriage, not exclusively locate in one plane between four connections between girder and the end carriage, certain dislocation up and down can be arranged, as ground not at ordinary times, can free adjustment, the built on stilts problem of driving wheel can not occur, each wheel of hoisting crane is all contacted with ground, the assurance hoisting crane can not turned round strength and derailing.
Description of drawings
Fig. 1 is the fixed form figure between girder of the prior art and the end carriage;
Fig. 2 is the structural representation of the utility model embodiment.
The specific embodiment
A kind of embodiment of crane beam, in Fig. 2, its girder 1 has two, two girders are parallel to each other, be respectively arranged with a butt beam 2 at the two ends of two girders, two butt beams 2 and two girders 1 form the integral body of a frame shape, position in the close bottom of the termination of girder 1 offers rectangular indentation, the rectangular indentation here is girder to be cut away the back near the angle of bottom form, the corresponding termination of corresponding end carriage 2 coincide and is fastened in the cooresponding rectangular indentation, two terminations that is to say every girder all are provided with rectangular indentation, and two terminations of every butt beam all are stuck in the rectangular indentation.Two end carriages 2 all are connected with two girders 1 by hinge, every girder 1 is set with two adapter plates 4 respectively in each rectangular indentation, two adapter plates 4 are provided with at interval, and the end of end carriage 2 that is to say that two adapter plates 4 are in the both sides of end carriage 2 between two adapter plates.Hinge 3 passes adapter plate, end carriage 2 and the inboard adapter plate in the outside successively, and the two ends of hinge 3 fixedly are located on the cooresponding adapter plate, the middle part of hinge pass end carriage and with the end carriage normal-running fit.
The stationkeeping that cooperates with hinge in the both sides of end carriage is provided with brace panel 5, has the through hole that passes for hinge on the brace panel 5, and hinge 3 passes brace panel 5.
Claims (2)
1. crane beam, comprise two girders that are parallel to each other, be respectively arranged with an end carriage at the two ends of two girders, position in the girder termination near the bottom offers rectangular indentation, the corresponding termination of corresponding end carriage coincide and is fastened in the cooresponding rectangular indentation, it is characterized in that: two end carriages all are connected with two girders by hinge, each rectangular indentation internal fixation of each girder is provided with the adapter plate of the both sides that are in end carriage respectively, the two ends of cooresponding hinge fixedly are located on the cooresponding adapter plate, the middle part of hinge pass end carriage and with the end carriage normal-running fit.
2. crane beam according to claim 1 is characterized in that: the both sides of described end carriage are provided with brace panel in the stationkeeping that cooperates with hinge, have the through hole that passes for hinge on the brace panel.
