[0002] A pile driver is composed of a pile hammer, a pile frame and auxiliary equipment. When in use, the pile hammer falls from a high place to hit the pile column so that the pile column penetrates the ground. In the actual working process, due to the soft ground, the pile column is easy to tilt when the pile hammer hits the pile column, resulting in pile driving failure. Based on the shortcomings of the existing pile driving device when in use, it is urgent to improve the existing pile driving device. Utility Model Content
[0003] The utility model aims to provide a positioning piling device for construction engineering, which has the advantages of simple structure, reasonable design, and can position piles to improve the success rate of piling.

In order to prevent the pile hammer from hitting the clamping mechanism, when the top of the pile column approaches the clamping mechanism, the two moving seats will move back to back in the left and right directions to make the clamping mechanism away from the pile column, so as to prevent the pile hammer from hitting the pile column and causing it to continue to penetrate into the ground, and the pile hammer will damage the clamping mechanism.

DETAILED DESCRIPTION
[0022] Example 1
[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a positioning piling device for construction engineering of this embodiment includes a frame 1, a positioning mechanism 2 and a hammering mechanism 3; wherein:
[0024] The positioning mechanism 2 is installed on the frame 1, and the positioning mechanism 2 includes two moving seats 4. The two moving seats 4 can move toward each other or move away from each other in the left and right directions, and a clamping mechanism 5 is installed on each moving seat 4;
[0025] The clamping mechanism 5 includes a mounting seat 51, an angle adjustment component 6 and two clamping plates 7; the mounting seat 51 includes two mounting plates 511 mounted on the movable seat 4, and the two mounting plates 511 are arranged vertically opposite to each other; each clamping plate 7 can be rotatably mounted between the two mounting plates 511, and the rotation axis of each clamping plate 7 is arranged along the up-down direction, and the rotation axis of the two clamping plates 7 is arranged side by side along the front-to-back direction, and a clamping opening 71 is formed between the two clamping plates 7; the angle adjustment component 6 is mounted on the mounting seat 51, and the angle adjustment component 6 is used to push the two clamping plates 7 to rotate at the same time to adjust the opening angle of the clamping opening 71; the clamping opening 71 of the clamping mechanism 5 on one movable seat 4 is opposite to the clamping opening 71 of the clamping mechanism 5 on the other movable seat 4;
[0026] The hammering mechanism 3 is installed on the frame 1, and the hammering mechanism 3 is above the positioning mechanism 2. The hammering mechanism 3 includes a pile hammer 31 that can move up and down, and the moving path of the pile hammer 31 passes through the center of the line connecting the two moving seats 4. When in use, the frame 1 is first fixed on the ground according to the pile driving position, and the opening angle of the clamping opening 71 of the clamping mechanism 5 is appropriately adjusted through the angle adjustment component 6 according to the thickness of the pile column. After that, the pile column is moved to the pile driving position under the action of the external lifting equipment, and the two moving seats 4 move toward each other in the left and right directions, so that the clamping opening 71 of the clamping mechanism 5 of one moving seat 4 cooperates with the clamping opening 71 of the clamping mechanism 5 of the other moving seat 4 to clamp and position the pile column, and finally the pile hammer 31 of the hammering mechanism 3 repeatedly hammers the top of the pile column, so that the pile column is vertically inserted into the ground. In order to prevent the pile hammer 31 from hitting the clamping mechanism 5, when the top of the pile column approaches the clamping mechanism 5, the two moving seats 4 will move in the left and right directions to move the clamping mechanism 5 away from the pile column, so as to prevent the pile hammer 31 from hitting the pile column and causing it to continue to penetrate the ground, and the pile hammer 31 will not damage the clamping mechanism 5. Since the pile column has been mostly inserted into the ground when the top of the pile column approaches the clamping mechanism 5, the two clamping mechanisms 5 will no longer clamp the pile column in the subsequent process, and the pile column will not tilt.
