AI Technical Summary
The existing counterweight mechanism of excavators requires bolts of different specifications, which are laborious to remove and require special tools. The removal process is difficult and inefficient.
It adopts a removable counterweight mechanism. The counterweight block body has vertical and horizontal grooves. Combined with the guide rail of the locking component, the two-way screw and the screw head, the counterweight can be installed or removed by manually turning the screw head without bolts or additional tools.
It significantly reduces the difficulty and force required for disassembling and assembling the counterweight, and improves the efficiency of disassembly and assembly.

Abstract
Claims
1. A removable counterweight mechanism for an excavator, characterized by, Includes the counterweight body and locking components, wherein: The upper surface of the counterweight body is provided with two sets of left-right symmetrical locking grooves. The locking grooves include vertical grooves extending along the front-back direction of the counterweight body and horizontal grooves extending along the left-right direction of the counterweight body. The vertical grooves start from the side wall of the counterweight body and extend towards the opposite side wall of the counterweight body, with one end open and the other end closed. The horizontal grooves start from the side wall of the closed end of the vertical grooves and extend perpendicularly to the vertical grooves and are connected to the vertical grooves. The horizontal grooves of each set of locking grooves extend towards the horizontal grooves of the other set of locking grooves. The width of the vertical groove is greater than or equal to the width of the horizontal groove. The locking assembly is fixedly connected to the excavator and includes a guide rail, a bidirectional screw, a screwing head, and two limiting blocks. The guide rail is fixedly connected to the excavator and has a through groove therein. The bidirectional screw is rotatably connected in the through groove. The screwing head is fixedly connected to one end of the bidirectional screw. The bidirectional screw has two sections of threads with opposite directions. The two limiting blocks are respectively threaded to the two sections of threads with opposite directions on the bidirectional screw.
2. The easily detachable counterweight mechanism of the excavator according to claim 1, characterized in that, The limiting block includes a limiting part, a sliding part, and a connecting part connecting the limiting part and the sliding part. The connecting part is disposed in the through groove and has a threaded hole that engages with the threaded screw. The limiting part and the sliding part are respectively disposed on both sides of the guide rail, wherein the sliding part is located closer to the excavator side that fixes the guide rail, and the size of the limiting part matches the size of the transverse groove.
3. The easily detachable counterweight mechanism of the excavator according to claim 1, characterized in that, The longitudinal extension distance of the preferred vertical groove satisfies: 1 / 2 H 2 / 3 H, the distance between the two sets of transverse grooves satisfies: 1 / 3 L <L1< 2 / 3 L, where H is the length between the front and rear side walls of the counterweight body, H1 is the front-to-back extension distance of the vertical groove, L is the length between the left and right side walls of the counterweight body, and L1 is the distance between the two sets of transverse grooves.
