First embodiment
Referring to fig. 1, the present embodiment provides an excavator 100, which includes a platform 110, an excavating component 130 disposed on the platform 110, and a supporting component 150 connected to the excavating component 130, wherein the supporting component 150 is used for supporting on a base surface 170 when the excavating component 130 works.
The excavating component 130 includes a boom 131, an arm 133, and a bucket 135 provided to the arm 133.
A third pin 138 is disposed at the top of the boom cylinder 132, one end of the arm 133 is rotatably connected to the third pin 138 through the arm cylinder 136, and the other end of the arm 133 is movably connected to the bucket 135. Meanwhile, a first pin 139 is disposed between both ends of the arm 133. The arm 133 is pivotally connected to an end of the boom 131 away from the platform 110 by a first pin 139. Thus, the boom 131, the boom cylinder 132, and the arm 133 constitute a triple link mechanism, and the arm 133 can be rotated with respect to the boom 131 by driving of the arm cylinder 136 to adjust the relative position of the arm 133 and the boom 131.
The bucket 135 is movably connected to one end of the arm 133 away from the arm cylinder 136 by a four-bar linkage. Specifically, the top of arm 133 is pivotally connected to bucket cylinder 141. A link 142 is provided between the bucket cylinder 141 and the bucket 135, and one end of the link 142 is rotatably connected to the bucket cylinder 141 and the other end is rotatably connected to the bucket 135. The joint of the link 142 and the bucket cylinder 141 is rotatably connected to one end of a rocker 144, and the other end of the rocker 144 is rotatably connected to the arm 133. Bucket 135 is driven by bucket cylinder 141 to adjust the position of bucket 135 with respect to arm 133, and thus the excavation angle of bucket 135 is adjusted.
The support assembly 150 is adapted to be supported to the base surface 170 during operation of the digging assembly 130. Specifically, the support assembly 150 includes a telescoping cylinder 152 and a support 154. The telescoping cylinder 152 is connected at one end to the support 154 and at the other end pivotally connected to the digging assembly 130.
To better accommodate the complexity of the site floor 170, the support 154 is, in this embodiment, movably coupled to the telescoping cylinder 152 such that the support 154 can be angularly oriented relative to the telescoping cylinder 152 to contact the floor 170. To improve the reliability of the support 154, the support 154 is also provided with a locking mechanism for preventing the support 154 from moving relative to the telescopic cylinder 152 to cause a problem of unstable support when the support 154 is adjusted to a proper position. In other embodiments, the support 154 may be fixedly connected to the telescopic cylinder 152, or a telescopic member may be added between the support 154 and the telescopic cylinder 152 to further increase the range of the support 154. In addition, in the present embodiment, the contact surface of the support 154 and the base surface 170 is provided with a slip prevention member 155 to improve the adhesion of the support 154 to the base surface 170. In other embodiments, anti-slip features or the like may be provided directly on the contact surface of the support 154.
In this embodiment, the support assembly 150 includes an adjustment cylinder 156. A fourth pin 157 is arranged between the two ends of the telescopic cylinder 152, one end of the adjusting cylinder 156 is rotatably connected to the fourth pin 157 between the two ends of the telescopic cylinder 152, and the other end of the adjusting cylinder 156 is rotatably connected to the excavating component 130, so that the telescopic cylinder 152, the excavating component 130 and the adjusting cylinder 156 together form a triple link mechanism, and the adjusting cylinder 156 can adjust the position of the telescopic cylinder 152, so that the angular position of the telescopic cylinder 152 relative to the movable arm 131 can be changed as required, and the situation of the base surface 170 on site can be better adapted. It is understood that in other embodiments, the adjustment cylinder 156 may not be provided if the ground conditions at the job site are not particularly complex.
The connection position of the supporting assembly 150 and the excavating assembly 130 can be flexibly set. Preferably, a telescopic cylinder 152 is rotatably coupled to the first pin 139, and an adjusting cylinder 156 is rotatably coupled to the boom 131. Specifically, one end of the telescopic cylinder 152 is connected to the support 154, and the other end is rotatably connected to the first pin 139. The movable arm 131 is provided with a first hinge seat 158, and the first hinge seat 158 is located between the first pin 139 and the second pin 134. The adjusting cylinder 156 has one end rotatably connected between both ends of the telescopic cylinder 152 and the other end rotatably connected to the first hinge base 158.
The working principle and working process of the excavator 100 are as follows:
when the excavator 100 is in a complicated geological and topographic state and an excavation target is relatively far, the boom cylinder 132 is contracted so that the boom 131 can drive the arm 133 farthest from the platform 110. Arm cylinder 136 is retracted to bring arm 133 into alignment with boom 131 as much as possible, and to position bucket 135 furthest from platform 110. After the working range of the bucket 135 is determined, the telescopic cylinder 152 is extended so that the support 154 contacts the base surface 170, and at the same time, the angle position of the telescopic cylinder 152 with respect to the boom 131 is adjusted by the adjustment cylinder 156, so that the support assembly 150 supports the cantilever beam formed by the excavating assembly 130 on the base surface 170, and the stability of the excavator 100 during working is maintained.
The excavator 100 is provided with the support assembly 150 for supporting the excavating assembly 130, so that the moment applied to the platform 110 of the excavator 100 by the excavating target weight is reduced, the stability of the excavator 100 during operation is effectively improved, the excavator 100 is prevented from tilting forward, and the potential safety hazard is reduced.
