Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy project construction, in particular to a rammer for water conservancy project construction. Background Technique
[0002] During the construction of water conservancy projects, when building foundation piles above the dam, it is usually necessary to use a rammer to perform fixed-point ramming at the position of the foundation piles, so that the soil at the bottom of the foundation piles is more stable, thereby making the foundation piles more stable. However, when a general rammer is performing ramming work, it is easy to shift its position when it bounces up and then falls during the ramming process. The deviation of the ramming center point is likely to cause uneven supporting force received by the bottom of the rammer, resulting in uneven reaction force received by the rammer and causing it to tilt, which brings inconvenience to operation. In severe cases, it may even cause the rammer to directly topple, increasing the usage risk during construction. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1-4 , the present utility model provides a rammer for water conservancy project construction, including a rammer 1. A support handle 2 for controlling balance is installed on the top of the rammer 1. A rammer pressure plate 3 for impact ramming is installed at the bottom of the rammer 1. A chassis 4 is installed at the bottom of the rammer pressure plate 3 through a connecting device 6. A positioning device 5 for positioning is arranged at the bottom of the chassis 4.
[0024] The positioning device 5 includes a positioning socket 51, anti-deviation blades 52, an inner limit plug 53 and a movable sleeve rod 54. The top end of the movable sleeve rod 54 is installed with the bottom of the chassis 4. The inner limit plug 53 for limiting is installed at the bottom end of the movable sleeve rod 54. The positioning socket 51 is movably sleeved with the bottom end of the movable sleeve rod 54. The anti-deviation blades 52 for improving the stability of the positioning socket 51 are installed on the outer wall of the positioning socket 51. The landing point of the chassis 4 is positioned through the positioning device 5, improving the ramming positioning accuracy.
[0025] Furthermore, the connecting device 6 includes a connecting cylinder base 61, a fixing nut 62, a pressing bolt 63, a connecting ring sleeve 64 and a pressing plate 65. A thread is provided at the bottom end of the connecting cylinder base 61. A threaded hole is provided at the top of the chassis 4. The connecting cylinder base 61 is installed with the top of the chassis 4 through the thread. The fixing nut 62 for driving the connecting cylinder base 61 to rotate is installed at the top end of the connecting cylinder base 61. The pressing bolt 63 is connected to the fixing nut 62 through the thread. The connecting ring sleeve 64 is rotatably installed on the outer wall of the pressing bolt 63 through a bearing. The pressing plate 65 for pressing and fixing is installed on the outer wall of the connecting ring sleeve 64. The rammer pressure plate 3 of the rammer 1 and the chassis 4 are installed and fixed through the connecting device 6.
[0026] Furthermore, the pressing plate 65 is obliquely installed. The end of the pressing plate 65 away from the connecting ring sleeve 64 is inclined downward. The rammer pressure plate 3 is pressed and fixed through the downward inclined end of the pressing plate 65. By pressing outwardly and obliquely through the four pressing plates 65, the effect of pressing and fixing the rammer pressure plate 3 is improved, preventing the rammer pressure plate 3 from sliding horizontally along the surface of the chassis 4.
[0027] Furthermore, there are four connecting devices 6 in total. The stability of the fixing is improved by pressing and fixing the rammer pressure plate 3 from different directions through the four connecting devices 6.
[0028] Further, cutting edges are provided on both the bottom edge and the side edge of the anti-deviation blade 52, reducing the resistance when the anti-deviation blade 52 is inserted into the ground and facilitating the installation operation.
[0029] Further, there are six anti-deviation blades 52 in total and they are equidistantly arranged outside the positioning insertion cylinder 51. By inserting the six anti-deviation blades 52 into the soil, the resistance when the positioning insertion cylinder 51 tilts is increased, so that the positioning insertion cylinder 51 maintains a vertical state.
[0030] Further, a notch for air circulation is provided on the surface of the inner limit plug 53. When the inner limit plug 53 moves up and down along the inside of the positioning insertion cylinder 51, air flows through the notch, balancing the air pressure difference between the upper and lower sides of the inner limit plug 53 and preventing it from affecting the movement of the inner limit plug 53.
[0031] During use, first insert the positioning device 5 into the position on the ground where ramming is required. After the positioning insertion cylinder 51 is inserted into the ground, the anti-deviation blade 52 is inserted into the ground inside the outside of the positioning insertion cylinder 51. At this time, the chassis 4 is closely attached to the ground surface. Remove one connecting device 6, and then push the rammer 1 to move from the position of the removed connecting device 6 to above the chassis 4, so that the rammer pressure plate 3 moves to directly above the chassis 4. Then install the removed connecting device 6 above the chassis 4. Install the connecting cylinder base 61 on the top of the chassis 4 through threads. Dial the pressing plate 65 to rotate to above the rammer pressure plate 3, and then rotate the pressing bolt 63 with a wrench. The pressing bolt 63 drives the connecting ring sleeve 64 to move downward through the action of the threads. The connecting ring sleeve 64 drives the pressing plate 65 to move downward and press on the rammer pressure plate 3. Through the cooperation of the four pressing plates 65, the rammer pressure plate 3 is pressed and fixed above the chassis 4 from above. After the installation is completed, start the rammer 1 to drive the rammer pressure plate 3 and the chassis 4 to jump up and down to ram the ground. When the chassis 4 rams, it drives the movable sleeve rod 54 to slide up and down along the inside of the positioning insertion cylinder 51. Through the cooperation of the movable sleeve rod 54 and the positioning insertion cylinder 51, the landing point of the chassis 4 is fixed, realizing the function of fixed-point ramming.
[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
