The counterweight block assembly comprises a buffer sleeve 30, wherein the buffer sleeve 30 is sleeved on a target pipeline 50, and a clamping jaw 220 acts on the buffer sleeve 30 when the pipeline is tightly held by a pre-tightening piece 20; since the friction between the jaw 220 and the target pipe 50 is small, the buffer sleeve 30 is provided to indirectly increase the friction between the jaw 220 and the target pipe 50 by using a large friction between the buffer sleeve 30 and the target pipe 50, thereby increasing the friction between the target pipe 50 and the weight body 40 and preventing the weight body 40 from being loosened and displaced. Meanwhile, the contact area between the buffer sleeve 30 and the target pipeline 50 is large, and the friction force between the buffer sleeve 30 and the target pipeline 50 is large, so that the fixing stability between the counterweight block assembly and the target pipeline 50 can be further ensured.
