Embodiment Construction
[0025] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. Various preferred embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0026] The inventor of the present case found that the existing crawler crane base structure has a large left and right width and a small front and rear width; the left and right sides are respectively connected with a crawler frame. Therefore, the inventor of this case considers that the crawler frame can also be connected by changing the setting direction of the base to reduce the width required for the transportation of the complete machine. Accordingly, see figure 1 and figure 2 , which shows the base structure provided by Embodiment 1 of the present invention. The base includes:
[0027] Base body 10;
[0028] The first connecting portion 11 and the second connectin...

The invention discloses a base, a traveling device and a crawler crane. The base includes: a base main body; a first connecting portion and a second connecting portion respectively arranged on the left and right sides of the base main body; a third connecting portion and a fourth connecting portion respectively arranged on the front and rear sides of the base main body; The first connecting portion and the second connecting portion are used to connect the base to the track frames on both sides of the base when the base is arranged along the first direction; the third connecting portion and the fourth connecting portion are used to connect the base along the first direction. When arranged in two directions, it is connected with the track frames on both sides of the base; the first direction and the second direction are perpendicular to each other. By adopting the base mechanism provided by the present invention, it is not necessary to disassemble the base from the crawler frame and transport it by auxiliary equipment such as flatbed trucks during transportation, nor does it need to build wider roads. It only needs to change the arrangement direction of the base and then connect with the crawler frame through the corresponding connection part. The operation is simple and the equipment cost is low, which is beneficial to reduce the transportation cost of the equipment.
Description
technical field [0001] The invention relates to the field of engineering machinery, in particular to a base, a traveling device and a crawler crane. Background technique [0002] Crawler crane is a kind of boom rotating crane that uses crawler to walk. Crawler cranes have the characteristics of large crawler ground area, good passability, strong adaptability, load-carrying walking and strong lifting capacity. [0003] Crawler crane is mainly composed of traveling device, slewing mechanism, upper vehicle, operating equipment and hook. Among them, the walking device is an important part to realize the movement and support of the whole machine. The traveling mechanism includes a base and a crawler frame, and a crawler frame is respectively connected to the left and right sides of the base. In order to meet the function of carrying a crawler crane, its crawler gauge (that is, the distance between the centers of the two crawler frames after the base is connected to the crawler...
