DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technicians.

[0022] like Figure 1-5 As shown, the portable micro pile driver comprises a micro pile driver body 1, a buffer device 2, a fixed plate 3, a support plate 4, a pile driving head 5, a pile driving barrel 6, a movable rod 7 and a handrail 8. A support plate 4 is fixedly installed at the lower part of the micro pile driver body 1, and the micro pile driver body 1 passes through the support plate 4 and is fixed to the support plate 4. A fixed plate 3 is arranged above the micro pile driver body 1, and the fixed plate 3 and the support plate 4 are connected by a buffer device 2, and the buffer device 2 can reduce the impact force generated by the micro pile driver during pile driving. The buffer device 2 is symmetrically arranged on both sides of the micro pile driver body 1, and comprises a connecting block 23, a spring 21 and a connecting rod 22. The connecting block 23 is fixedly welded to the lower part of the fixed plate 3 and the upper part of the support plate 4 respectively, and the upper and lower ends of the connecting rod 22 are connected to the connecting block 23 by a spring 21, and the elastic force of the spring 21 plays a role of vibration buffering as a whole.

[0023] The pile driving head 5 is fixedly connected to the lower end of the micro pile driver body 1, and a threaded hole is provided at the lower end of the pile driving head 5, which is threadedly connected to the pile driving barrel 6; the pile driving barrel 6 includes a screw 61 and a barrel 62, and a screw 61 is fixed on the top of the barrel 62, and the screw 61 is threadedly connected to the pile driving head 5. The pile driving head 5 is threadedly connected to the pile driving barrel 6, and the user can make pile driving barrels 6 of different sizes according to the needs. When piling, different types of pile driving barrels 6 can be replaced by threaded connection according to the shape and size of the pile body, so that the pile driving barrel 6 and the pile body are more adapted, which is convenient for the smooth progress of the pile driving work and improves the work efficiency of the pile driving. The fixed plate 3 is symmetrically provided with movable rods 7 on both sides, and the movable rods 7 include movable inner rods 71 ​​and movable outer rods 72, and the movable inner rods 71 ​​and movable outer rods 72 are both tubular structures. The movable outer rod 72 is sleeved with the movable inner rod 71, and the movable outer rod 72 sleeves the movable inner rod 71. The movable inner rod 71 can move up and down in the movable outer rod 72. The movable rod 7 supports the micro pile driver, preventing the micro pile driver from shifting forward, backward or left and right. The user only needs to control the micro pile driver to move up and down, which greatly reduces the control force required by the user and is easy to use. The movable outer rod 72 is symmetrically provided with a limit nut 73, and the limit bolt 74 is threadedly connected with the limit nut 73 and passes through the rod wall of the movable outer rod 72 and the movable inner rod 71 to fix the movable outer rod 72 and the movable inner rod 71. During transportation, the limit bolt 74 needs to be used to fix the movable outer rod 72 and the movable inner rod 71 to prevent the movable outer rod 72 from falling off during transportation and affecting use; when in use, the limit bolt 74 needs to be unscrewed to facilitate the movable inner rod 71 to move up and down in the movable outer rod 72, adjust the position of the pile barrel 6, and facilitate pile driving.

[0024] A locking mechanism 11 is provided at the bottom of the movable rod 7, which can connect the movable inner rod 71 with the movable outer rod 72. Before the micro pile driver works, the limit bolt 74 needs to be loosened and removed. When the micro pile driver completes piling and moves to another pile body, the locking mechanism 11 is required to fix the movable inner rod 71 and the movable outer rod 72 to prevent them from falling. The fixing of the two rods also facilitates the micro pile driver to be vertically inserted into the ground.

[0025] The locking mechanism 11 includes a block 111, a block connecting rod 112, a limit spring 113, a baffle 114, a support rod 115, a first truncated cone 116 and a second truncated cone 117; the block 111 is fixedly connected to the block connecting rod 112, and the side of the block 111 is a right-angled trapezoid; a through hole is provided on the wall of the movable inner rod 71, and the limit spring 113 is fixed in the through hole, and the block connecting rod 112 passes through the limit spring 113 and can move linearly left and right in the through hole; the baffle 114 is located inside the movable outer rod 72, and the support rod 115 is vertically fixed to the center of the baffle 114, the first truncated cone 116 is fixed to the top of the support rod 115, and the second truncated cone 117 is symmetrically arranged with the first truncated cone 116 and sleeved on the support rod 115. The large round surface of the first truncated cone 116 is fixed to the support rod 115. When the mini pile driver is pressed downward for the first time, the block 111 and the block connecting rod 112 on the movable inner rod 71 contact the edge of the first truncated cone 116 downward, and the block 111 and the block connecting rod 112 are continuously pressed to move to both sides along the side of the first truncated cone 116, driving the limit spring 113 to contract. When they reach below the large circular surface of the first truncated cone 116, the limit spring 113 drives the block 111 and the block connecting rod 112 to reset and clamp the large circular surface of the first truncated cone 116, so that the movable inner rod 71 and the movable outer rod 72 can be fixed. At this time, the movable outer rod 72 will not fall off when the mini pile driver moves to another pile body, which is convenient to use. When the micro pile driver is pressed downward for the second time, the movable inner rod 71 reaches the baffle 114, the block 111 moves along the second truncated cone 117 from the large circular surface to the small circular surface, the limit spring 113 is compressed and reset, and when lifted, the block 111 clamps the second truncated cone 117 and lifts it to contact the first truncated cone 116, the limit spring 113 is reset, compressed and reset, and the movable inner rod 71 can be separated from the movable outer rod 72, so that the micro pile driver can move up and down conveniently during piling.

[0026] The lower end of the movable outer rod 72 is fixedly connected with a conical head 10, which is convenient for inserting into the ground to support the micro pile driver. The upper part of the fixed plate 3 is fixedly connected with a handrail 8, and the user can hold the handrail 8 to control the micro pile driver. The handrail 8 is provided with a rubber sleeve 9, which is sleeved on both ends of the handrail 8 to play an anti-slip role and also to reduce the numbness of the user's hand caused by the vibration of pile driving.

The pile driving tube 6 can be replaced according to the actual situation of the pile body. The movable rod 7 has a positioning function. The user only needs to control the micro pile driver to move up and down to vertically drive the pile, which can greatly reduce the occurrence of pile body deviation, is convenient for users to use, and greatly improves work efficiency.

[0028] The working process of this utility model:

[0029] When the utility model is used, the pile driving cylinder 6 is selected according to the size of the pile body. The user holds the two ends of the handrail 8 with both hands, inserts the movable rod 7 into the ground, places the main body 1 of the micro pile driver just above the pile body, loosens the limit bolt 74, places the pile driving cylinder 6 directly opposite the pile body, starts the micro pile driver, and then performs the pile driving operation.

[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
