Quick-exhaust type heavy hammer impact piling machine and quick-exhaust type piston impact piling machine

Abstract

The invention discloses piling machines which respectively are a quick-exhaust type heavy hammer impact piling machine and a quick-exhaust type piston impact piling machine. Both the piling machines comprise two impact cylinders; each pair of impact cylinders is laterally symmetrically arranged on a bracket; each impact cylinder comprises a cylinder, an upper cover board and a lower bottom plate; each upper cover board is connected with the corresponding lower bottom plate; each cylinder is arranged between the corresponding upper cover board and the corresponding lower bottom plate; the lower bottom plates are arranged on the corresponding brackets; one impact cylinder of each piling machine is provided with a gas inlet valve and an exhaust valve; the inlet valves are positioned on the corresponding upper cover boards; the exhaust valves are positioned on the lower surfaces of the corresponding lower bottom plates; and the lower surfaces of the lower bottom plates are also provided with quick-exhaust valves. According to the invention, the quick-exhaust valves are arranged on the lower surfaces of the corresponding lower bottom plates, so that lower cavities of the cylinders in the two piling machines more smoothly exhaust and an effect of an impact force is more sufficiently played.

Description

[0001] This application is a divisional application. The original application date: 2011.03.20, application number: 201110078093.6, title of the invention: device for blocking dam breaches. Technical field [0002] The invention relates to a pile driver, which is a quick-displacement heavy hammer impact pile driver and a quick-displacement piston impact pile driver. Background technique [0003] In the application file of 201010184689.X filed by me, the device for piling at the crevasse of the dam is disclosed. After the implementation of this scheme, piling at the crevasse of the dam can indeed be driven, but the following problems are still found in use: ①, combination After the steel pipe pile enters the water, due to the intense water flow, the pile and the inner wall of the bracket are tightly pressed, and it is useless to extend the pile to the bottom of the dam in the torrent. ②. Because piles are driven in the rapids, the piles will inevitably be a little skewed after they...

Problems solved by technology

[0003] In the application document that the application number 201010184689.X proposed by me discloses the device for driving piles at the breach of the embankment, after the implementation of the scheme, it is indeed possible to drive piles at the breach of the embankment, but it is found that the following problems still exist in use: ①. After the steel pipe pile enters the water, due to the strong current, the pile and the inner wall of the bracket are pressed tightly, and it is useless to extend the pile into the bottom of the dam in the torrent.

When the inclination of the pile is large, it is difficult to ensure the verticality of the mobile platform because there is no leveling device on the bracket

③. Since there is no dedicated connector, the speed of forming a pile network from individual piles is slow and the operation is more complicated

④. The exhaust of the cylinder lower cavity of the piston impact cylinder and the hammer impact cylinder is not smooth, so that the impact force output by the impact cylinder cannot be fully exerted

However, if the section of the exhaust pipe is increased, the bending radius of the exhaust pipe must be increased, and the gas distribution section of the gas distribution valve must also be increased, which will increase the volume and weight of the pile driver.

⑤. The push rod of the hammer impact cylinder is composed of a solid push rod and a hollow push rod. The manufacturing process is complicated, and the work reliability is poor and easy to damage

If the rescue equipment cannot be deployed due to the harsh environment and there are fewer rescuers, then even if the piles have been laid, the breach cannot be quickly sealed.
