Detailed Description
The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, the cast pile removing device includes a supporting member 1, a cast pile clamp 2, a screw rod 3 and a handle 4, where the supporting member 1 is used to abut against teeth during pile pulling, and further supports the screw rod 3, in this embodiment, the supporting member 1 is a circular barrel-shaped structure, one end of the supporting member 1 is open, and the size of the opening is slightly smaller than that of the teeth, so as to ensure that one end of the supporting member 1 can stably abut against the surface of the teeth during pile pulling, and the other end of the supporting member 1 is provided with a threaded hole 6 in threaded fit with the screw rod 3. The shape of the support 1 is not limited to this, and may be in the form of a U-shaped frame, a tripod, or the like. Cast pile anchor clamps 2 and be used for cliping cast pile 9, cast pile anchor clamps 2 are located support piece 1's inside, cast pile anchor clamps 2's one end is provided with two at least inside extending block tongues 5, block tongues 5 are used for blocking cast pile 9's draw-in groove, cast pile anchor clamps 2's material is stainless steel or titanium alloy, the preference is stainless steel, cast pile anchor clamps 2's the other end and the one end welded connection of screw rod 3, of course also can be with cast pile anchor clamps 2 and screw rod 3 integrated into one piece, screw rod 3 and threaded hole 6 screw-thread fit, the other end and the handle of screw rod 3 are connected.
When the pile is pulled out, the handle 4 is rotated forward to enable one end of the cast pile clamp 2 to extend out of one end of the support piece 1, the clamping groove of the cast pile 9 is clamped by the clamping tongue 5, the support piece 1 is rotated to enable one end of the support piece 1 to abut against the surface of the tooth, the handle 4 is rotated reversely, the cast pile clamp 2 drives the cast pile 9 to move outwards, and finally the cast pile 9 is pulled out of the tooth.
Further, in another preferred embodiment of the present invention, as shown in fig. 2, two observation holes 7 are symmetrically disposed on the side wall of the supporting member 1, the observation holes 7 are used for facilitating the doctor to observe the pulling-out condition of the cast pile 9, and adjust the direction of the power as required to ensure that the cast pile 9 is pulled out from the teeth smoothly.
