Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model discloses to how to connect the problem on the chassis with support detachable, provide a chassis structure and excavator.
As shown in fig. 1 to fig. 3, an embodiment of the present invention provides a chassis structure, including: two side frames 1 that set up relatively and set up two center frame 2 between side frame 1, side frame 1 with center frame 2 is formed with a plurality of installation terminal surfaces, still includes:
the fixed plate 3 is welded on the installation end surface formed by the side frame 1 and the central frame 2;
and the support 4 is fixed on the fixing plate 3 through bolts, specifically, the support arranged at one end of the side frame 1 is a guide wheel support 41, and the support arranged at the other end of the side frame 1 is a motor support 42.
It should be noted that the embodiment of the utility model provides a through welding the fixed plate on the mounting end face that centre frame and side bearer formed, pass through the bolt fastening with the support on the fixed plate to realized dismantling of support and connected, when the support damaged in the field, can dismantle the support of damage fast and change new support.
Specifically, the support 4 comprises a mounting plate 43, the mounting plate 43 has the same shape and size as the fixing plate 3, and a plurality of first mounting holes are formed in the mounting plate 43; a plurality of second mounting holes are formed in the fixed plate 3, wherein the first mounting holes correspond to the second mounting holes, and the mounting plate 43 is fixed on the fixed plate 3 by penetrating the first mounting holes and the second mounting holes through bolts; the number of the first mounting holes is at least four, and correspondingly, the number of the second mounting holes is at least four. The first mounting hole and the second mounting hole are penetrated through by a bolt, so that the mounting plate 43 is fixed on the fixing plate 3.
It should be noted that, when the support 4 is installed, the bolt sequentially passes through the first mounting hole and the second mounting hole and then is in threaded fit with the nut, and specifically, a gasket may be disposed between each component. The fixing of the mounting plate 43 on the fixed plate 3 is thus achieved, completing the detachable connection between the support 4 and the central frame 2 and the side frame 1 of the chassis structure. Compare in current with the support welding compare on the chassis, can accomplish the maintenance operation through only changing the support when the support takes place to damage.
Specifically, the chassis structure further includes:
and the limiting structure 5 is arranged on the mounting plate 43 or the fixing plate 3.
It should be noted that the limiting structure 5 may be a rectangular block-shaped structure, and is fixed on the mounting plate 43 or the fixing plate 3 by welding. The fixed plate with the mounting panel includes at least one terminal surface that is in the coplanar, limit structure 5 is fixed plate 3 or on this terminal surface of mounting panel 43, specifically, when limit structure 5 is fixed on fixed plate 3, limit structure 5 with the terminal surface that fixed plate 3 contacted is being close to one side of mounting panel 43 includes an extension structure, extension structure is installed at mounting panel 43 when on fixed plate 3, can with mounting panel 43 butt is in extension structure department, thereby realized right mounting panel 43's location conveniently carries out the installation of bolt. When the limit structure 5 is fixed on the mounting plate 43, the principle is the same.
Specifically, when the limiting structure 5 is disposed on the fixing plate 3, it is located on the end surface of the fixing plate 3 far away from the ground. And when the limiting structure 5 is arranged on the mounting plate 43, the limiting structure is positioned on the end surface of the mounting plate 43 far away from the ground.
It should be noted that, will limit structure 5 sets up on the terminal surface of keeping away from ground, can prevent track wearing and tearing center frame 2 of excavator, when the inside butter of the long-time operation track spring in field is not enough, the track can sink, uses limit structure 5 this moment can effectively prevent track and center frame 2 contact, prevents both wearing and tearing.
The embodiment of the utility model provides an still provide an excavator, including foretell chassis structure.
It should be noted that, the excavator with the chassis structure realizes the detachable connection of the support, and when the support is damaged in the field, the damaged support can be rapidly detached to replace a new support.
The foregoing is directed to the preferred embodiments of the present invention, and it will be understood by those skilled in the art that various changes and modifications may be made without departing from the principles of the invention, and that such changes and modifications are intended to be included within the scope of the invention.
