Description

Technical Field

[0001] The utility model belongs to the technical field of new energy project construction, and particularly relates to a tool for clamping the core of a photovoltaic micro-pile. Background Technique

[0002] At present, in the photovoltaic power generation field area on the plateau slopes with scattered sites, there are large changes in terrain and geology, and it is inevitable to occupy steep slopes of 30° to 45°. Due to geological differences, four hole-forming methods can be used for the steep slopes: for pure soil, a hand-held auger can be used to drill holes; for any two mixtures of soil, gravel soil and rock, only a high-power 5-person-operated manual air drill such as a small bee drill can be used; for exposed rock above medium hardness, a pile foundation with a smaller hole diameter can be adopted, and a single-person hand-held air drill can be used; for soft rock exposed rock pile foundation with a larger hole diameter, in addition to using a small bee drill, a single-person-operated water mill drill can also be used; while the diameter of the photovoltaic micro-pile is only 170 mm, but the depth is 1.45 m. The simple water mill drill bit has no device for clamping the core, and it depends on manual skills to clamp it into the drill bit or break it and then take it out with a Luoyang shovel, which is time-consuming and laborious. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a tool with a simple structure, convenient operation, which can easily take out the core or fragments in the photovoltaic micro-pile hole and improve the construction efficiency of the photovoltaic micro-pile.

[0004] The technical solution of the utility model is as follows: a tool for clamping the core of a photovoltaic micro-pile, including: a force transmission rod, a connecting sleeve, clamping pieces, steel wire ropes, and pulleys. The force transmission rod passes through both ends of the connecting sleeve. A circular ring is arranged at the lower end of the force transmission rod. The upper end of the force transmission rod is bent to form a large circular ring. The end of the upper end of the force transmission rod is a pointed head and is higher than the large circular ring. The large circular ring is located above the upper end of the connecting sleeve. Four clamping pieces are arranged at the lower end of the connecting sleeve. The four clamping pieces are composed of two U-shaped steel plates stacked and connected. One of the U-shaped steel plates is fixedly connected to the end of the lower end of the connecting sleeve. Pulleys are arranged near the ends of the clamping pieces. Two steel wire ropes cross each other and pass through the four pulleys respectively and are fixedly connected to the circular ring at the lower end of the force transmission rod. The force transmission rod passes through the two U-shaped steel plates.

[0005] Further, the lower end of the clamping piece is trapezoidal and slightly turned outwards, and the thickness of the clamping piece is 2 mm.

[0006] Further, the end of the upper end of the force transmission rod is led out from the tangent direction of the large circular ring, and the end of the upper end of the force transmission rod is 3 cm higher than the large circular ring.

[0007] Advantages of the present utility model: A core clamping tool for photovoltaic micro-piles of the present utility model clamps the core by rotating the force transmission rod during use to tighten the steel wire rope to make the clamping pieces clamp the core, then the connecting sleeve is lifted out of the photovoltaic micro-pile hole, and then the force transmission rod is loosened to make the clamping pieces automatically reset to put down the core. The whole operation process is convenient and fast, and the core or fragments in the photovoltaic micro-pile hole can be easily taken out, improving the construction efficiency of photovoltaic micro-piles; in addition, the upper end of the force transmission rod is pointed and can be used to pry off the core that has not been broken by the water mill drill, further improving the construction efficiency of photovoltaic micro-piles; in short, the core clamping tool for photovoltaic micro-piles of the present utility model has a simple structure, is easy to operate, can easily take out the core or fragments in the photovoltaic micro-pile hole, and improves the construction efficiency of photovoltaic micro-piles.

[0012] In the description of the present utility model, it should also be noted that unless otherwise clearly defined and limited, the term "connection" 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, a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meaning of the above terms in the present utility model can be understood according to specific situations.

[0013] Such as Figure 1-2As shown, a photovoltaic micro-pile core clamping tool includes: a force transmission rod 1, a connecting sleeve 2, clamping pieces 3, a steel wire rope 4, and a pulley 5. The force transmission rod 1 passes through both ends of the connecting sleeve 2. A circular ring is provided at the lower end of the force transmission rod 1. The upper end of the force transmission rod 1 is bent to form a large circular ring. The end of the upper end of the force transmission rod 1 is a pointed head and protrudes above the large circular ring. The large circular ring is located above the upper end of the connecting sleeve 2. Four clamping pieces 3 are provided at the lower end of the connecting sleeve 2. The four clamping pieces 3 are composed of two U-shaped steel plates overlapped and connected. One of the U-shaped steel plates is fixedly connected to the end of the lower end of the connecting sleeve 2. A pulley 5 is provided near the end of the clamping piece 3. Two steel wire ropes 4 cross each other and pass through the four pulleys 5 respectively and are fixedly connected to the circular ring at the lower end of the force transmission rod 1. The force transmission rod 1 passes through the two U-shaped steel plates.

[0014] Preferably, the lower end of the clamping piece 3 is trapezoidal and slightly turned outwards, and the clamping piece 3 is 2 mm thick.

[0015] Preferably, the end of the upper end of the force transmission rod 1 is led out from the tangential direction of the large circular ring, and the end of the upper end of the force transmission rod 1 protrudes 3 cm above the large circular ring.

[0016] During use, the clamping tool is inverted and placed into the photovoltaic micro-pile hole. First, use the end of the upper end of the force transmission rod 1 to pry off the core. Then, invert and turn over the clamping tool and place it into the photovoltaic micro-pile hole in the positive direction. The construction worker holds the connecting sleeve 2 with the left hand and holds the large circular ring on the force transmission rod 1 with the right hand. Rotate the force transmission rod 1 so that the large circular ring drives the circular ring at the lower end of the force transmission rod 1 to rotate, thereby pulling the clamping piece 3 by the steel wire rope 4. When the force transmission rod 1 is released, the clamping piece 3 will automatically reset, and at this time the core will fall.
