Embodiment Construction
[0019] Specific embodiments are described below with reference to the accompanying drawings.
[0020] like figure 1 As shown, the crawler hydraulic excavator chassis 100 in this embodiment includes an X-shaped frame 1 and a crawler beam 7. The frame 1 is mainly composed of a cylinder in the middle and four cylinders extending from the cylinder 13 to the left and right sides. It is composed of one arm beam, and the four arm beams are box-shaped structures, which are formed by welding the side plate, the top plate 11 of the frame, and the bottom plate 12 of the frame. The ends of the left two arm beams and the ends of the right two arm beams are respectively fixedly connected with a track beam 7, and the bottom and top of the cylinder 13 are respectively welded with the bottom plate 12 and the top plate 11 of the frame to form a middle of the frame. Cavity for center fitting. On the crawler beam 7 of the chassis 100 are installed driving wheels, guide wheels, carrier wheels, r...

The invention relates to a crawler-type hydraulic excavator chassis, in order to solve the problem of difficulty in arranging a large-sized toolbox on the upper body of the existing crawler-type excavator; and provides a crawler-type hydraulic excavator chassis, which includes an X-shaped frame, and the middle of the frame has a lower end A cylinder welded with the bottom plate of the frame, the bottom plate of the frame is provided with a maintenance window, a detachable bottom cover is arranged in the maintenance window, and the upper part of the bottom cover is provided with a box with an open side, and the opening of the box faces the bottom of the chassis. Directly in front or behind, the box body is attached to the inner wall of the cylinder at its opening, the cylinder wall is provided with an extraction window opposite to the opening of the box, and the cylinder is provided with a lock or open to extract objects window box door. In the crawler hydraulic excavator chassis of the present invention, the space on the excavator chassis is fully utilized, the problem of difficult design and layout of the crawler hydraulic excavator complete machine tool box is solved, and the process is simple and the manufacturing cost is low.
Description
technical field [0001] The invention relates to an excavator chassis, and more particularly, to a crawler hydraulic excavator chassis and an excavator. Background technique [0002] Existing excavators are all designed with a toolbox with a certain storage space on the upper platform to store a large number of on-board tools and maintenance parts, and with the user's higher requirements for the convenience of maintenance, these on-board tools and The number and volume of skin care products are increasing. However, with the wide application of short-tail and zero-tail excavators, and the requirements of new excavators in terms of appearance, field of vision, and transportation size, the size and layout of the upper platform are becoming more and more compact, and it is almost impossible to design large-scale excavators. sized toolbox to store high-volume, bulky parts. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provi...
