[0002] There are two types of pile clamping devices for static pile drivers in the prior art. One is the clamping of pile clamping oil cylinders directly, which requires four oil cylinders. The actual clamping force is 1.414 times that of an oil cylinder; the only way to increase the clamping force is to increase the diameter of the oil cylinder, which is often limited by the size of the equipment assembly and cannot be realized
The other is to rely on the pulling force of the oil cylinder to pull the clamping of the splint clamp pile. The clamping force of the clamping clamp is greater than that of the clamping clamp, but the clamping weight is large, the manufacturing cost is high, and the overall processing is difficult. Work) acts on the splint, and its resultant force is hardly greater than 600 tons

Embodiment Construction
[0011] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings. as attached figure 1 As shown, the scissors clamp device is arranged between the upper pressure pile beam 12 and the lower pressure pile beam 10. In the illustration, the device has two layers of scissors clamps stacked together, and each layer has two oil cylinders 3, and the oil cylinder 3 The rear ends of the curved shears 5 and the straight shears 9 are hinged through the oil cylinder connecting shaft 1, and the curved shears 5 and the direct shears 9 are connected as one by the fixed long axis 8, which is the fulcrum of the lever. attached figure 2 , 3 , 4 is the top view after removing the upper pressure pile beam 12. in the attached figure 2 Among them, the clamping plate 7 is a clamping plate for clamping the tubular pile, and the clamping plate 7 and the clamping bottom plate 6 are hinged to the front ends o...

The invention discloses a static press-in pile driver scissor clip device, which belongs to the technical field of construction machinery. The static press-in pile driver scissor clip device contains an upper press-in pile beam, a lower press-in pile beam, an oil cylinder and a splint. Both ends of the oil cylinder are hinged with the rear end of straight snips or curved scissors. The front end of the straight snips or curved scissors is hinged with the splint. The middle part of the straight snips or curved scissors is connected with the upper and lower press-in pile beams together by a fixed prolate axis. The oil port of the oil cylinder is installed at one end without pole cavity. The device has reasonable design, simple and convenient structure. As the device of the invention has reasonable design and simple structure, the cost of same tonnage press-in pile driver hydro cylinder is exponentially reduced, the structure weight is reduced about 20%, the structure cost is correspondingly reduced about 20%, and a large-tonnage static press-in pile driver which is above 1000 tons is possibly manufactured. The large-tonnage static press-in pile driver can replace the existing hole drilling pile machine, so that the cost of high-rise house foundation is reduced more than 50%.
