Description

Technical Field

[0001] The utility model relates to the technical field of power penetration test auxiliary devices, in particular to a super-heavy power penetration instrument lifting device. Background Art

[0002] like Figure 1 As shown, the super-heavy dynamic probe 5 generally includes a probe rod 51, an outer convex ring 52 provided on the top of the probe rod 51, and a probe 53 provided on the bottom of the probe rod 51. The outer convex ring 52 is provided with lifting parts 54 extending outward on opposite sides.

[0003] When conducting cone penetration tests to determine the mechanical properties of rock and soil, the probe of an ultra-heavy dynamic penetration instrument often becomes stuck in the soil and rock, making it difficult to remove. Traditionally, the ultra-heavy dynamic penetration instrument is removed by lifting a core hammer via a wire rope and fixed pulley, then using the core hammer to reversely strike the probe, gradually extracting it. This causes significant wear and damage to the equipment. If the probe is stuck too tightly, even this counterattack can sometimes be difficult to remove. Furthermore, the load on the wire rope and the entire power system increases dramatically during the extraction process, posing a significant safety hazard to machinery, equipment, and personnel, and significantly reducing test efficiency.

[0004] The existing Chinese patent document with application number 201620707988.X discloses a device for lifting a dynamic sounding hammer and vertically adjusting a probe rod, comprising a top disc, a fixed pulley, a wire rope, a tripod, a tripod positioning support rod, and a steel plate for fixing the probe rod. A probe rod hole I is provided in the middle of the top disc for easy passage of the probe rod. Pulleys are symmetrically installed on the lower surface of the top disc, and a wire rope is wound around each fixed pulley. One end of the wire rope is connected to the weight, and the other end is a free end. A tripod is provided under the top disc, and the upper end of the tripod is connected to the top disc. A tripod positioning support rod is provided between two adjacent legs of the lower part of the tripod. A steel plate for fixing the probe rod is horizontally installed on the tripod positioning support rod. The fixed probe rod steel plate is provided with a probe rod hole II for easy passage of the probe rod. The probe rod hole II is on the same plumb line as the probe rod hole I. This device for lifting a dynamic sounding hammer and vertically adjusting a probe rod has the following deficiencies:

[0005] 1) The wire rope and the weight are connected by binding, which is inconvenient to operate and has low safety;

[0006] 2) The weight is lifted synchronously by two steel ropes, which has poor stability, requires large lifting force and consumes a lot of energy;

[0007] 3) The probe rod is prone to tilt during the lifting process, resulting in poor stability and safety. Utility Model Content

The pull rope is wound around the fixed pulley and the movable pulley, and the hook is hung on the movable pulley.

[0015] A hanging rod is provided on the top of the hook member, and the hanging rod is rotatably connected to the center of the movable pulley through a rotating shaft.

[0016] The ultra-heavy-duty dynamic probe lifting device further comprises a guide mechanism, which is arranged on the support frame and is used for circumferential limiting and vertical guidance during the lifting process of the ultra-heavy-duty dynamic probe.

The interior of the hook part 31 forms a accommodating space 33 for accommodating the top of the super-heavy power probe 5. Limit blocks 34 are respectively slidably provided on the side walls on both sides of the hook part 31. The inner end face of the limit block 34 is provided with a limit arc surface 341. The limit arc surface 341 is used to cooperate with the outer convex ring 52 of the super-heavy power probe 5 to limit the rotation of the outer convex ring 52.

[0039] Usage process: First, slide the limit blocks 34 on both sides of the hook 31 to the high position; then, put the hook 31 on the top of the super-heavy power probe 5, so that the supporting blocks 32 on both sides of the hook 31 respectively support the lifting parts 54 on both sides of the outer convex ring 52 of the super-heavy power probe 5; secondly, slide the limit blocks 34 on both sides of the hook 31 to the low position, respectively clamped on both sides of the outer convex ring 52, and limit the rotation of the outer convex ring 52; then, through the lifting action of the lifting mechanism 2, lift the super-heavy power probe 5 until the probe 53 is pulled out; then, slide the limit blocks 34 on both sides of the hook 31 to the high position, and remove the hook 31. This super-heavy power probe lifting device is connected to the super-heavy power probe 5 by the hook 31 for lifting, and the connection and separation operations are convenient.

Figure 7 As shown, the arc-shaped limiting surfaces 411 of the two guide blocks 41 are combined to form a full circle, and the probe rod 51 is arranged in the full circle. The full circle plays a role of circumferential limiting and vertical guiding for the probe rod 51.

[0046] Further, if Figure 2As shown, in this embodiment, support seats 11 are provided at positions corresponding to the support frame 1 and each guide block 41 , and a slide rod 412 is provided on the side of the guide block 41 away from the limiting arc surface 341 , and the slide rod 412 slides through the corresponding support seat 11 .

[0047] Further, if Figure 2 and Figure 4 As shown, in this embodiment, the sliding adjustment assembly 42 includes a mounting base 421 and a sliding adjustment member 422.
