Description

Technical Field

[0001] The utility model relates to the technical field of piling equipment, in particular to a piling device for municipal engineering. Background Art

[0002] Pile driving is a construction method of hammering wood piles or stone piles into the ground. Commonly used pile driving methods include hammering, vibration, water jetting and pile pressing. In the process of piling, a municipal engineering pile driving device is widely used. At present, the cross-section of the pile driving blocks of most municipal engineering pile driving devices on the market is smooth. When piling, the downward force of piling is dispersed over the entire surface of the cross-section, and all the force cannot be concentrated on one point for piling, so that the piling force is dispersed and reduced, reducing work efficiency. In addition, some existing municipal engineering pile driving devices do not have a device for positioning the pile column. When piling, the pile column is prone to tilt, which is not conducive to the piling work. For this reason, application No. 2019209045 discloses a municipal engineering pile driving device, which belongs to the field of construction engineering. , a piling device for municipal engineering comprises a piling support frame, a hydraulic cylinder is arranged at the lower end of the piling support frame, a connecting block is fixedly connected to the lower end of the hydraulic cylinder, and a piling block provided therein has a lower end section arranged in a hemispherical shape, so that when piling is being driven, all the force of the piling block is concentrated on the hemispherical convex point, and when the piling column is pressed downward, the force is concentrated and not dispersed, so that the piling force becomes larger, the piling speed becomes faster, and the work efficiency is improved, and the installation structure of the piling block is simple, and when the piling block is worn out and needs to be replaced after long-term use, it is convenient for the staff to replace it, and the piling device for municipal engineering is provided with a first clamping block and a second clamping block, and the piling column can be clamped by the mutual cooperation between the first clamping block and the second clamping block, so that the piling column will not tilt during the piling process, which is conducive to the piling work;

[0003] The municipal engineering piling device disclosed in the above patent still has some shortcomings during use: 1. The method of clamping and positioning the piling column by the cooperation of the first clamping block and the second clamping block can effectively reduce the inclination of the piling column during the piling process, but due to the existence of the clamping force, the piling column will generate a large friction force during the downward movement, which will affect the downward movement of the piling column; 2. The method of achieving piling by squeezing the piling column by moving the piling block downward only relies on the downward squeezing force to drive the pile, lacks the downward knocking shock force, makes the piling effect unsatisfactory, and thus affects the piling efficiency; Based on the above situation, we propose a municipal engineering piling device.

[0026] Working principle: When in use, for pile driving operation, first turn on the reciprocating push rod motor 8, and the output shaft of the reciprocating push rod motor 8 drives the U-shaped moving rod 6 to move up and down reciprocatingly. When the U-shaped moving rod 6 moves upward, it drives the two positioning rods 13 to slide upward in the corresponding guide grooves 15 through the two connecting blocks 7. When the positioning rod 13 drives the corresponding extrusion rod 12 to move upward until it contacts with the bottom of the cross bar 10, the extrusion rod 12 that continues to move upward squeezes the cross bar 10 to move upward, and the cross bar 10 stretches the spring 11 upward. The cross bar 10 also drives the counterweight knocking block 5 to move upward through the counterweight rod 9. When the counterweight knocking block 5 moves upward to a higher position, the reciprocating push rod motor 8 is immediately turned off, and then the pile column is placed between the two positioning splints 1, and the counterweight knocking block 5 moves upward to a higher position. The heavy knocking block 5 is located just above the pile column, and the two knobs 16 are respectively rotated in the positive direction, and the knobs 16 drive the corresponding screw rods 3 to rotate. Under the action of the threaded holes provided on the U-shaped mounting seat 100, the screw rods 3 rotate and move at the same time, and the screw rods 3 drive the corresponding positioning clamping plate 1 to move in the direction close to the pile column, and the positioning clamping plate 1 also drives the guide rod 4 to move laterally. When the positioning clamping plate 1 drives the corresponding positioning ball 2 to contact the outer side of the pile column, the knob 16 is stopped from being rotated. At this time, the two positioning clamping plates 1 cooperate with the multiple positioning balls 2 to position the pile column, and the setting of the positioning balls 2 can drive the positioning balls 2 to rotate by friction during the downward movement of the pile column, thereby effectively reducing the friction force during the downward movement of the pile column, thereby improving the stability of the pile column during the downward movement;

[0027] After the pile column is positioned, the reciprocating push rod motor 8 is turned on again, so that the U-shaped moving rod 6 is transformed into moving downward, and the U-shaped moving rod 6 drives the two extrusion rods 12 to move downward and relax the extrusion force on the cross bar 10 through the two connecting blocks 7 and the two positioning rods 13 in turn, and the counterweight knocking block 5 moves downward to knock the top of the pile column under the action of gravity and the elastic force of the spring 11. The reciprocating push rod motor 8 continues to drive the U-shaped moving rod 6 to move up and down reciprocatingly, so that the counterweight knocking block 5 moves up and down cyclically to knock and vibrate the pile column, and the downward movement height of the counterweight knocking block 5 is determined by the top position of the pile column. Under the knocking and vibration force, the pile column moves downward, thereby completing the effect of piling, and through the cyclic knocking and vibration piling method, the pile column can move downward stably, thereby improving the piling effect and efficiency;

[0028] After the pile is driven, the two knobs 16 are respectively rotated in opposite directions, so that the two positioning clamps 1 are transformed to move away from the pile column, thereby releasing the positioning of the pile column and the entire device can be removed.
