The specific working process of the invention is as follows: in the initial state of the device, the pressing disc 7 is pressed downwards manually and a plurality of ropes 6 of the pressing disc 7 are tightened, the tightened ropes 6 drive the sliding block 5 to move upwards and compress the pressure spring 10 in the process, meanwhile, the sliding block 5 moves upwards to drive the flat steel stick 3 to move upwards, the flat steel stick 3 retracts into the circular tube 1 under the guiding action of the guide tube 2, the circular tube 1 in the state is pressed towards the underground of the pile foundation at the moment, the tip of the circular tube 1 moves downwards for a certain distance, the pressing disc 7 is loosened, the flat steel sticks 3 extend outwards under the action of the guide tube 2 under the resetting action of the pressure spring 10, the extending ends are inserted into the surrounding soil of the circumference, the diameter of a similar circular structure formed by the flat steel sticks 3 is larger than that of a flood control pile to be inserted into the pile foundation, the extending end of the electric push rod 12 retracts firstly after the completion, and the disc 11 is sleeved on the part of the circular tube 1 above the ground, meanwhile, the lower end face of the disc 11 is horizontal to the ground and contacts with the ground, and after the installation is finished, the extending end of the electric push rod 12 extends out, so that the arc-shaped plate 17 contacts with and extrudes the outer circular face of the circular tube 1.
Striking on the pressure plate 7 is achieved through manual holding and hammering matching operation, in the process, the outer circular surface of the circular tube 1 is contacted and extruded by the arc-shaped plate 17 driven by the electric push rod 12, at the moment, the circular tube 1 is fixed, the pressure plate 7 moves downwards, the hinged shafts of the first connecting rods 8 and the second connecting rods 9 move in the direction away from the circular tube 1, contraction of the rope 6 is achieved in the process, the rope 6 contracts to drive the sliding block 5 to move upwards and drive the flat steel sticks 3 to be recovered, in the process, force of hammering is continued after the flat steel sticks 3 are completely recovered, the lower end face of the cylindrical body is contacted and extruded to the driving switch 13, the driving switch 13 is extruded to achieve retraction of the extending end of the electric push rod 12, at the moment, hammering force is continuously applied to the circular tube 1 to achieve downward movement of the circular tube 1, the hammer head is separated from the pressure plate 7 after hammering is completed, at the moment, a combination of the first connecting rod 8 and the second connecting rod 9 which are in a V shape and are unfolded to form a coil spring under the resetting effect of the pressure spring 10 and the resetting effect of the pressure spring 10 Regional coaxial state, pressure spring 10 no longer is tied up this moment, pressure spring 10 is released and pushes away the flat steel stick 3 downwards by the power that the hammering was held, this in-process realizes stretching out of flat steel stick 3 at the guide effect of stand pipe 2, can withdraw the back earlier and realize hammering downwards of pipe 1 when hammering once more after flat steel stick 3, reciprocating cycle finally drives pipe 1 downwards to the assigned position, and accomplish stretching out of many times steel flat stick in this process, realize the detection of multilayer soil layer debris.
When the flat bamboo slips and meets debris, rope 6 relaxes but the flat bamboo slips of this in-process stretches out and is blockked this moment, rope 6 can not be by the supplementary tensile of the flat bamboo slips of steel that stretches out, pressure-sensitive switch 15 at this moment opens the position that the pilot lamp 14 of corresponding position lights up thereby the position of judging the stone, supplementary subsequent excavation, if the flat bamboo slips of steel can stretch out when rope 6 relaxes all the time, then rope 6 all is in tensile state at whole in-process, pressure-sensitive switch 15 closes all the time, pilot lamp 14 remains the not bright state all the time, prove that there is not debris below this pile foundation position can carry out the pile driving operation of flood control stake.
Compared with the traditional equipment, the device has the following advantages:
1. this device can outwards stretch out through the setting of a hollow pipe 1 in pipe 1 and sign 3, earlier realize that flat steel signs 3 contracts of returning when hammering pressure disk 7, realize the lower of pipe 1 again and visit, pipe 1 visits the completion back down, flat steel signs 3 resets and stretches out, carry out the detection of a major diameter to this region, thereby get rid of the hard thing of this regional stone, this device adopts the mode of intermittent type hammering, can effectually carry out the effect that down-drive also can realize layering detection to pipe 1, make whole stone detection process more high-efficient laborsaving.
2. This device passes through the setting of pilot lamp 14 and pressure-sensitive switch 15 for when a certain band steel is signed 3 and is met hard thing and can't reset, the band steel of other positions is signed 3 and is not influenced and reset, and this can effectually demonstrate the position relation of this regional stone, only need carry out the simple adjustment of position when carrying out flood control pile and can realize the pile of this regional flood control pile, avoid the waste of the manpower and materials that the stone excavation brought.
3. Electric putter 12 provides a supporting role for pipe 1 in this device for the band steel is signed 3 and is just can realize the lower of pipe 1 after being retracted completely, and this in-process guarantees that pipe 1 and band steel are signed 3 and have a seesaw order, prevents that band steel from signing 3 and is damaged.
The invention has novel concept, smart structure and strong practicability, and effectively solves the problems of low detection efficiency and complex operation caused by repeated plugging and unplugging of the steel drill rod at different positions of a pile foundation in the existing flood control pile driving detection process.
