Description

technical field [0001] The invention relates to the field of construction engineering, in particular to an automatic punching pile driver control system for complex terrain. Background technique [0002] The traditional punching pile driver is composed of hoist, brake control, clutch control lever, pile frame, pile hammer and auxiliary equipment, etc., and generally requires manual operation. During the working process, the construction personnel control the hoist to lift and lower the pile hammer by frequently and repeatedly operating the clutch and brake operating levers. Use the impact force generated by the free fall of the pile hammer to periodically impact and break the target foundation until a pile hole with a certain depth and diameter is formed. During the punching process, use the slag pump to clean the debris in the hole in time In order to speed up the punching speed, after the punching is completed, the steel cage installation and concrete pouring are carried ...

AI Technical Summary

Problems solved by technology

[0003] At the same time, in the piling process of the traditional pneumatic punching pile driver, when the pile hammer hits the bottom of the pile with its own gravity, due to the inertia of the pile hammer, the winding device will be driven to rotate at an accelerated speed. If the winding device cannot be braked in time, The wire rope will fall endlessly due to inertia, and the subsequent clutch time will cause the length of the remaining rope to be too long

The length of the remaining rope is too long, which not only reduces the efficiency of the piling system, but also because the pile hammer is deposited at the bottom of the pile for a long time, it is easy to cause failures such as suction hammer and hammer jamming, which poses a great safety hazard

However, if the brake is too early, the remaining rope will be too tight, and the pile hammer will not reach the bottom of the pile or just reach the bottom of the pile, which will not only make the piling ineffective, but also cause the wire rope to break due to sudden braking. Security risks

[0004] It can be seen that the traditional punching pile driver has extremely high requirements for the construction personnel, the labor intensity is high, the safety factor is low, and the construction quality is difficult to guarantee.

However, the construction requirements and difficulties in different geological environments are also different. For example, in complex terrain conditions such as inclined rock, the requirements for construction personnel will be higher. Ordinary punching piles often have partial holes. The rock capacity is greatly reduced, which greatly reduces the piling efficiency
