Detailed Description
As shown in fig. 1-2, a foldable small pile driver comprises a flat car 1, a folding bracket 2 anchored on the flat car 1, and a drop hammer 31 connected to the top of the folding bracket 2 by a rope;
the top of the folding bracket 2 is provided with a reel 32 driven by a motor 33, and the motor 33 is electrically connected with an automatic reciprocating control circuit; the rope of the drop weight 31 is wound on the reel 32; the motor 33 may be a stepping motor 33 to improve accuracy and prevent the falling weight 31 from being excessively raised or excessively lowered.
The drop weight 31 can be removed during transport.
When the folding support 2 is in a fully opened state, a hole for the pile rod 5 to vertically pass through is formed in the position, right below the drop hammer 31, of the flat car 1.
The folding bracket 2 is anchored with a guide cylinder 23 for preventing the pile rod 5 from being tilted when driving the pile, and the guide cylinder 23 is coaxial with the pile rod 5 when the folding bracket 2 is fully opened.
As shown in fig. 3, the folding bracket 2 is a rectangular frame, one edge of which is disposed against the upper surface of the flat car 1 and is rotatably connected to the flat car 1 with the edge against the flat car 1 as a rotation axis; the rectangular frame is locked through the telescopic diagonal brace 21 after being erected, the telescopic diagonal brace 21 is a telescopic rod with a locking device, one end of the telescopic diagonal brace 21 is rotatably connected with the flat car 1, the other end of the telescopic diagonal brace 21 is rotatably connected with the rectangular frame at a position higher than the flat car 1, and rotating shafts rotatably connected with the two ends of the telescopic diagonal brace 21 are arranged in parallel to the edges of the rectangular frame, which are attached to the flat car 1.
The flat car 1 is also provided with a containing frame 13 for fixing the rectangular frame after the rectangular frame is laid flat, and the rectangular frame is connected with the containing frame 13 through a quick-release connecting piece such as a buckle or a steel ball bolt; so as to avoid the rectangular frame from moving around when in turnover.
The folding support 2 is further anchored with a sliding rod 22, the sliding rod 22 is arranged at a longitudinal axis position when the folding support 2 is completely opened, a sliding groove 221 is arranged on the sliding rod 22 along the length direction of the sliding rod 22, the opening of the sliding groove 221 is gradually reduced from inside to outside, the drop hammer 31 is connected with the sliding rod 22 in a sliding mode through a connecting rod, one end of the connecting rod of the drop hammer 31 is fixedly connected with the drop hammer 31, and the other end of the connecting rod is arranged in the sliding groove 221 in a sliding mode after being expanded. Since the weight of the drop hammer 31 is small, the drop hammer may be deflected due to strong wind to affect piling, and thus is fixed slightly.
The guide cylinder 23 is anchored on the slide bar 22; a pile top protection sliding table 4 for protecting the top of the pile rod 5 is arranged on the sliding rod 22 at a position higher than the guide cylinder 23 in a sliding manner, and the pile top protection sliding table 4 is positioned under the drop hammer 31 after the folding support 2 is completely unfolded; the pile top protection sliding table 4 is connected with the sliding rod 22 in a sliding mode through a connecting rod, one end of the connecting rod of the pile top protection sliding table 4 is fixedly connected with the pile top protection sliding table 4, and a sleeve is anchored at the other end of the connecting rod; as shown in fig. 4, the sleeve is sleeved on the sliding rod 22 and is connected with the sliding rod 22 in a sliding manner, and the inner wall of the sleeve is anchored with a protrusion which is inserted into the sliding groove 221 and used for preventing the sleeve from rotating. The drop hammer 31 itself can be kept on the plumb line by gravity, and therefore, it is not necessary to provide a similar structure, but the sleeve of the pile top protection slide table 4 may be rotated, and if the sleeve is rotated, the pile top protection slide table 4 cannot be padded on the top of the pile rod 5, and thus cannot function.
The upper and lower surfaces of the pile top protection slipway 4 should be paved with wear-resistant and impact-resistant materials, such as monel or fluororubber, so that the noise during pile driving can be reduced, and the top of the pile rod 5 can be protected.
A fixed rod 12 for stabilizing the folding bracket 2 is vertically anchored on the flat car 1, and the fixed rod 12 is detachably connected with the folding bracket 2 when the folding bracket 2 is completely unfolded. The locking means of the telescopic brace 21 is generally relatively fragile and is very easily damaged after being subjected to vibration during pile driving, so that it is necessary to further fix it by means of the fixing rod 12 to reduce the vibration to which it is subjected.
A stationary hoe 11 is anchored at the bottom of the flat car 1, the stationary hoe 11 is a telescopic rod with a locking device, the telescopic rod is vertically arranged, the upper end of the telescopic rod is anchored at the bottom of the flat car 1, and the lower end of the telescopic rod is anchored with a ground nail.
