Description

Technical Field

[0001] The utility model relates to the technical field of pile driving equipment, in particular to a pile driving machine capable of monitoring a pile body. Background Art

[0002] Pile driving equipment is mainly divided into two types: static pile driving and vibrating hammer pile driving. Both types of equipment can drive the pile into a pre-set hole. The verticality of the pile needs to be monitored during the process of driving it into the hole to ensure the quality of the pile driving.

When the hammering plane in this scheme is in a horizontal state, the infrared light emitted by the infrared sensor points to the center position of the detection circular hole, and the pile hammer keeps fitting with the end face of the end of the pile body. Once the pile body is tilted, the pile hammer tilts accordingly, so that the infrared light emitted by the vertically downward infrared sensor on the internal hanging ball cannot pass through the circular hole downward, thereby generating feedback;

[0004] The shortcomings of the above-mentioned prior art solution are: the pile hammer in the above-mentioned solution is connected by an articulated manner and can rotate. Although it is convenient to fit the end of the pile body, it is also easy to tilt due to the imbalance of the force of the pile hammer itself, thereby causing the pile body to tilt, that is, the pile cannot be pressed stably, and the infrared sensor used to monitor the verticality is connected to the swingable hanging ball, which is easy to shake due to the influence of external factors, and cannot be stably monitored, thereby affecting the monitoring results.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 3 As shown, a pile driver capable of monitoring a pile body comprises a main frame 1 and a hydraulic push rod 8. A universal connector is provided on the main frame 1. The main frame 1 is connected to the top of the hydraulic push rod 8 through the universal connector. The bottom end of the hydraulic push rod 8 is a telescopic end. The universal connector comprises a ball shell 5 and a universal ball 6. The ball shell 5 is connected to the main frame 1. The universal ball 6 is connected to the ball shell 5 in a coordinated rotation manner. The universal ball 6 is connected to the hydraulic push rod 8. The universal ball 6 can rotate in the ball shell 5, so that the hydraulic push rod 8 can swing down by gravity and remain in a vertical position. A fixing mechanism matched with the universal ball 6 is provided on the main frame 1. The fixing mechanism comprises a fixed pressure plate 3 and a hydraulic telescopic rod 2. The hydraulic telescopic rod 2 is connected to On the main frame 1, the fixed pressure plate 3 is connected to the telescopic end of the hydraulic telescopic rod 2, and the fixed pressure plate 3 is matched above the universal ball 6. A plurality of protruding particles 4 are distributed on the fixed pressure plate 3, and a plurality of hole grooves 7 matching with the protruding particles 4 are distributed on the universal ball 6. When the pile driver moves to the corresponding hole position, the hydraulic push rod 8 swings downward to a vertical position by relying on the universal ball 6 under the action of gravity. After the position of the hydraulic push rod 8 is stable, the hydraulic telescopic rod 2 is started to shrink, driving the fixed pressure plate 3 to press onto the universal ball 6. The protruding particles 4 on the fixed pressure plate 3 interact with the hole grooves 7 on the universal ball 6, so that the position of the universal ball 6 is fixed, thereby fixing the hydraulic push rod 8 in a vertical position;

[0025] A vertical detector 9 is installed on the outer wall of the hydraulic push rod 8, and the vertical detector 9 is convenient for workers to observe whether the hydraulic push rod 8 is in a vertical position;

[0026] The telescopic end of the hydraulic push rod 8 is connected to a pile hammer 10, and the pile hammer 10 is used to vertically press the pile body 12 into the corresponding hole position;

[0027] A connecting ring 11 is connected to the pile hammer 10 through a rod body, and the axes of the connecting ring 11 and the pile hammer 10 coincide with the axes of the hydraulic push rod 8; a plurality of threaded connection blocks 13 are circumferentially distributed on the connecting ring 11, and an elastic connection member is arranged between each threaded connection block 13 and the connecting ring 11, and the elastic connection member includes a connecting sleeve 14 and a connecting spring 16; a plurality of guide rods 15 are circumferentially connected to the connecting ring 11, and the connecting sleeve 14 is slidably arranged on the guide rod 15 and connected to the corresponding threaded connection block 13, and the connecting spring 16 is connected between the guide rod 15 and the connecting sleeve 14;

[0028] Each threaded connection block 13 is threadedly connected with an adjusting screw 17, and a pressure sensing switch 18 is installed at the end of the adjusting screw 17 close to the center of the connecting ring 11. An alarm 19 electrically connected to each pressure sensing switch 18 is installed on the main frame 1;

[0029] When pile pressing is carried out, the connecting ring 11 is placed at the outer periphery of the top end of the pile body 12, and then the adjusting screw 17 at each position is rotated and moved, so that the adjusting screw 17 drives the corresponding pressure sensing switch 18 to approach the pile body 12 and maintain the set spacing, and then pile pressing is carried out. During the pile pressing process, if the pile body 12 tilts and exceeds the allowable error value, the pile body 12 will contact the pressure sensing switch 18 at the corresponding position, and the pressure sensing switch 18 will generate induction, so that the alarm 19 will sound an alarm, so that the workers can be informed in time and make corrections in time. When the pressure sensing switch 18 is squeezed by the pile body 12, the pressure sensing switch 18 pushes the corresponding threaded connection block 13 through the adjusting screw 17, and the threaded connection block 13 slides along the guide rod 15 through the connecting sleeve 14 and compresses the connecting spring 16, so that the tilted pile body 12 can be prevented from squeezing the pressure sensing switch 18 and the adjusting screw 17 to cause damage, and the pile body 12 can also be prevented from being damaged.

[0030] The working principle of the utility model is as follows: first, the pile driver is moved to the corresponding hole position, so that the hydraulic push rod 8 is swung downward to a vertical position by relying on the universal ball 6 under the action of gravity, and after the position of the hydraulic push rod 8 is stabilized, the hydraulic telescopic rod 2 is started to shrink, driving the fixed pressure plate 3 to press onto the universal ball 6, and the protruding particles 4 on the fixed pressure plate 3 interact with the hole grooves 7 on the universal ball 6, so that the position of the universal ball 6 is fixed, thereby fixing the hydraulic push rod 8 in a vertical position;

[0031] At this time, the pile body 12 is vertically hoisted into the hole, and the pile hammer 10 at the telescopic end of the hydraulic push rod 8 is made to contact the end of the pile body 12, and the connecting ring 11 moves to the outer periphery of the top of the pile body 12 with the pile hammer 10, and then the adjusting screws 17 at various positions on the connecting ring 11 are rotated and moved, so that the adjusting screws 17 drive the corresponding pressure sensing switches 18 close to the pile body 12 and maintain the set spacing, and then the pile is pressed. During the pile pressing process, if the pile body 12 tilts and exceeds the allowable error value, the pile body 12 will contact the pressure sensing switch 18 at the corresponding position. 8, the pressure sensing switch 18 generates induction, so that the alarm 19 sounds an alarm, so that the workers can be informed in time and make corrections in time, and when the pressure sensing switch 18 is squeezed by the pile body 12, the pressure sensing switch 18 pushes the corresponding threaded connection block 13 through the adjusting screw 17, and the threaded connection block 13 slides along the guide rod 15 through the connecting sleeve 14 and compresses the connecting spring 16, so that the inclined pile body 12 can be prevented from squeezing the pressure sensing switch 18 and the adjusting screw 17 to cause damage, and the pile body 12 can also be prevented from being damaged.

[0032] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
