[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use.

[0024] Example 1

[0025] like Figure 1 As shown, an excavator with a lateral counterweight includes a frame, a counterweight structure 2 is arranged on the side of the frame, a sliding frame 3 is arranged on the frame, the counterweight structure 2 is slidably connected to the sliding frame 3 through a slideway, and a driving unit for driving the counterweight structure 2 to slide is arranged on the frame.

[0026] A counterweight block is arranged on the side of the frame. When one side is operating, the counterweight structure 2 on the other side is extended by the driving unit, which can effectively improve the overall stability of the machine and the lateral operating ability; when one side does not need to operate, the counterweight structure 2 on the other side is driven by the driving unit to slide and retract along the slideway, thereby reserving more space for the operation on the other side.

[0027] Example 2

[0028] The difference between this embodiment and embodiment 1 is that counterweight structures 2 are arranged on both sides of the frame to facilitate the excavator to operate in either direction. When operating in one direction, the counterweight structure 2 in the other direction is extended to improve the overall stability.

[0029] like Figure 2 and Figure 3 As shown, the drive unit includes a telescopic cylinder 4 arranged on the frame, and the telescopic end of the telescopic cylinder 4 is connected to the counterweight structure 2. In this embodiment, the telescopic cylinder 4 is installed on the frame through a connecting block 42, and the telescopic end of the telescopic cylinder 4 is connected to the counterweight structure 2 through a mounting seat 41. The mounting seat 41 and the telescopic cylinder 4 can be connected by welding or bolts. In this embodiment, bolt connection is adopted to facilitate the replacement of the telescopic cylinder 4. The telescopic cylinder 4 is extended and retracted to drive the mounting seat 41 to move, so that the counterweight structure 2 can be synchronously extended and retracted under the drive of the mounting seat 41.

[0030] The sliding frame 3 is symmetrically arranged on both sides of the counterweight structure 2. In this embodiment, the slideway includes a guide slideway 311, which is arranged on the side of the sliding frame 3 facing the counterweight structure 2. The counterweight structure 2 is slidably connected to the guide slideway 311 through a protrusion. The upper and lower ends of the side of the counterweight structure 2 are provided with protrusions. The guide slideway 311 on the sliding frame 3 is arranged corresponding to the protrusions, thereby improving the stability of the sliding process of the counterweight structure 2. Further, in order to improve the stability of the counterweight structure 2 in a static state, the counterweight structure 2 is meshed with the slideway.

[0031] In this embodiment, the slideway also includes a limiting slideway 312, which is arranged on the top surface of the sliding frame 3, and the limiting seat 5 is slidably connected in the limiting slideway 312, and the limiting seat 5 is clamped in the limiting slideway 312, and the limiting seat 5 is connected to the counterweight structure 2 through the limiting block, and the limiting seat 5 is detachably connected with a buckle 51, and a plurality of limiting grooves 313 are provided on both sides of the limiting slideway 312, and the buckle 51 is clamped with the limiting groove 313. The setting of the limiting seat 5 and the limiting block in the limiting slideway further provides protection for the safety of the counterweight structure 2; the buckle 51 can be clamped at different positions of the limiting groove 313, so that the movement range of the counterweight structure 2 can be limited, and when the telescopic cylinder 4 is removed for installation or maintenance, the buckle 51 can prevent the counterweight structure 2 from falling off by limiting the limiting seat 5.

[0032] The limiting seat 5 is provided with a fixed slot 52 , which is opposite to the limiting groove 313 , and the buckle 51 is simultaneously engaged in the fixed slot 52 and the limiting groove 313 , so that the buckle 51 can be conveniently removed from or inserted into the limiting seat 5 .

[0033] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0034] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
