The specific working process of the invention is as follows: when the device is used, the lower ends of a plurality of steel rods 2 all extend out of the ground, the device is moved to a foundation pile position, four steel rods 2 are manually pressed at the moment, the four steel rods 2 are all inserted into one part below the ground, the first U-shaped rod and the second U-shaped rod are positioned at positions close to each other in an initial state, the lower ends of the four steel rods 2 can be ensured to be closer to the same horizontal plane, after the four steel rods 2 are all inserted into one part below the ground, the electric telescopic rod 5 is driven by a pneumatic motor to move in a reciprocating manner, when the extending end of the electric telescopic rod is in a retraction state, the piston cylinder 6 is positioned at the upper end part of the piston cylinder 6, along with the extension of the electric telescopic rod 5, the piston rod 7 extrudes gas in the piston cylinder 6 into the pneumatic telescopic rod 11 in the left-right direction through the first hose 13, the pneumatic telescopic rod 11 in the left-right direction extends, and extrudes the steel, the friction force between the steel rods 2 in the left and right directions and the ground is increased after the steel rods 2 in the left and right directions are extruded, the first U-shaped structure is fixed in an auxiliary mode, the extending end of the electric telescopic rod 5 extends out to extrude the second U-shaped rod downwards, the steel rods 2 in the front and back directions are extruded downwards for detection, when the extending end of the electric telescopic rod 5 extends out continuously, the pressure in the lower half section of the piston cylinder 6 is increased continuously, redundant gas in the piston cylinder 6 is discharged from the pressure valve 8 when the set value of the pressure valve 8 at the lower end of the piston cylinder 6 is reached, the upper end of the piston cylinder 6 is aerated through the check valve 9, and therefore in the extending process of the electric telescopic rod 5, the arc-shaped friction plates 12 on the left and right sides can extrude the steel rods 2 in the.
When the extending end of the electric telescopic rod 5 retracts, the piston rod 7 moves upwards, in the process, the piston rod 7 extrudes gas at the upper end of the piston cylinder 6 to enter the front-back pneumatic telescopic rod 11 and enables the front-back pneumatic telescopic rod 11 to extend and extrude steel rods 2 in the front-back direction through the arc-shaped friction plates 12, at the moment, the electric telescopic rod 5 is in a retraction state, but the second U-shaped structure is limited, when the electric telescopic rod 5 retracts, the first U-shaped structure is pulled downwards, the steel rods 2 in the left-right direction are extruded and detected downwards, meanwhile, the piston rod 7 can assist the left-right pneumatic telescopic rod 11 to retract when moving upwards, meanwhile, redundant gas at the upper end of the piston cylinder 6 is discharged to the outside after reaching a set value of the pressure valve 8, the gas at the lower end of the piston cylinder 6 is supplied with gas from the outside through the.
When the detection is completed, the first hose 13 is manually screwed off from the pneumatic telescopic rod 11 in the left-right direction, the second hose 14 is screwed off from the pneumatic telescopic rod 11 in the front-back direction, the first hose 13 is screwed on the pneumatic telescopic rod 11 in the front-back direction, and the second hose 14 is screwed on the pneumatic telescopic rod 11 in the left-right direction, at the moment, the electric telescopic rod 5 is driven to reciprocate, the front-back reverse steel chisel 2 is limited when the extension end of the electric push rod extends, the first U-shaped structure moves upwards, the left-right direction steel chisel 2 is limited when the electric push rod retracts, the second U-shaped structure moves upwards, and the cycle operation can pull out all the four steel chisels 2.
When the steel chisel 2 can not be pressed downwards after encountering hard objects, the overload protection of the first motor is stopped, and then the situation that the hard objects exist below the ground can be judged.
Compared with the traditional equipment, the device has the following advantages:
1. this device is designed to the general light characteristics of quality of check out test set quality for the side has inserted the drill rod 2 of the below ground partly around inserting left and right side drill rod 2 extrusion through arc friction disc 12, drill rod 2 makes around the extrusion drill rod 2 and ground frictional force increase, when the drill rod 2 of direction is deepened downwards about the drive in this process, device gravity itself and the drill rod 2 of fore-and-aft direction are enough to overcome the frictional force of extruding about the steel rod 2 makes reaction force, make can not cause the upwards moving up of being by this device when drive drill rod 2 is downward.
2. Supporting and stretching into through the drill rod 2 that corresponds of alternate drive makes whole drill rod 2 insertion process more high-efficient, compares and inserts a drill rod 2 at every turn and has effectively improved the speed that the pile foundation detected for a plurality of position homoenergetic obtain effectual detection, detect thoroughly more and comprehensively.
3. When the electric telescopic rod 5 extends and retracts, the piston rod 7 synchronously moving with the electric telescopic rod extends air, in the process, a small part of air can extend the air pressure telescopic rod 11, redundant air pressure is discharged under the action of the pressure valve 8 after reaching certain pressure, and therefore in the plugging and unplugging process, the arc-shaped friction plate limits the drill rod 2 timely, so that the whole process is more efficient and faster.
The invention has novel concept, skillful structure and strong practicability, and effectively solves the problems that the long time is consumed for driving steel rods one by one when flood control pile foundation hard objects are detected, and the maneuverability of equipment is poor because the dead weight of the equipment needs to be increased when the steel rods are driven into a plurality of hard objects at one time.
