Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution:

[0022] In this technical solution, a cement mixing pile machine pile positioning device includes a base frame 100 and a support frame 101 set on the top of the base frame 100. A fixed frame 102 is provided inside the support frame 101, and an adjustable connecting component 200 is provided on the fixed frame 102. A positioning component 300 is provided on the connecting component 200. An adjustable support leg 400 is provided on the outer wall of the support frame 101. The support leg 400 includes a telescopic bracket 401 slidably set on the bottom outer wall of the support frame 101, a connecting plate 402 slidably set on the outer wall of the support frame 101, and a connecting rod 403 rotatably set between the connecting plate 402 and the support frame 101. An insert rod 404 is provided at the bottom of the bracket 401. The positioning component 300 includes a screw 301 that passes through the connecting seat 203 and is threadedly connected to it, a drill rod 302 set at the bottom of the screw 301, and an adjusting handwheel 303 set at the top of the screw 301.

[0023] In this technical solution, the connecting plate 402 is moved downward along the support frame 101101. When it moves downward, it drives the connecting rod 403 to move downward, thereby causing the support leg 400 to expand outward and increase the support range of the support leg 400. With the insertion rod 404 inserted into the ground, its stability is further improved. At the same time, the support leg 400 is placed at the force contact point, thereby effectively improving the stability of the device and avoiding instability during use. The connecting component 200 can improve the stability of the positioning component 300 under force and facilitate the adjustment of the position of the positioning component 300. By rotating the adjusting handwheel 303, the screw 301 is moved up and down along the connecting seat 203, thereby moving the drill rod 302 up and down, so that the drill rod 302 contacts the ground and drills out the pile location point on the ground, thus completing the site selection of the pile location point.

[0024] In some technical solutions, the bracket 401 includes a sleeve rod 405 disposed on the bottom outer wall of the support frame 101, a connecting rod 406 slidably connected to the sleeve rod 405, and a positioning plate 407 connected to the end of the connecting rod 406.

[0025] In this technical solution, when the connecting rod 403 moves downward, it can drive the connecting rod 406 and the positioning plate 407 to move away from the support frame 101, thereby expanding the support leg 400, increasing its support range, and improving the stability of the device.

[0026] In some technical solutions, the connecting rod 403 is rotatably connected between the connecting plate 402 and the positioning plate 407, and the insertion rod 404 is connected to the bottom of the positioning plate 407.

[0027] In some technical solutions, a locking bolt 408 is provided between the support frame 101 and the connecting plate 402, and a threaded hole 103 that mates with the locking bolt 408 is provided on the outer wall of the support frame 101.

[0028] In this technical solution, the adjusted connecting plate 402 can be fixed by the locking bolt 408 and the threaded hole 103, thereby fixing the support range of the support leg 400 and preventing the support leg 400 from moving and becoming unstable during use.

[0029] In some technical solutions, the connecting component 200 includes a first movable frame 201 slidably disposed on the outer wall of the fixed frame 102, a second movable frame 202 slidably disposed on the outer wall of the first movable frame 201, and a connecting seat 203 fixedly disposed on the second movable frame 202.

[0030] In some technical solutions, both the fixed frame 102 and the first movable frame 201 are provided with positioning holes 204, and the first movable frame 201 and the fixed frame 102, as well as the second movable frame 202 and the first movable frame 201, are fixed together by positioning holes 204 and positioning pins 205.

[0031] In some technical solutions, the fixed frame 102, the first movable frame 201, and the second movable frame 202 are all frame structures.

[0032] In this technical solution, there are force points at both ends of the frame, so the structure of the connecting component 200 is more stable than the support frame 101, which can prevent the device from tilting during use. At the same time, it can also improve the stability of the positioning component 300 when it moves, and further improve the stability of the device during use. With the positioning hole 204 and positioning pin 205, it is easy to limit and fix the positioning component 300 after it has moved.

[0033] Working process and principle: During use: the connecting plate 402 is moved downward along the support frame (101) 101 by moving the connecting plate 402. When it moves downward, it will drive the connecting rod 403 to move downward, thereby driving the support leg 400 to expand outward, increasing the support range of the support leg 400. With the set insertion rod 404 inserted into the ground, its stability performance is further improved. At the same time, the support leg 400 is also at the force contact point, thereby effectively improving the stability of the device and avoiding instability during use. With the set fixed frame 102, the first moving frame 201 and the second moving frame 202, the positioning component 300 can be moved. With the set positioning hole 204 and positioning pin 205, it is convenient to limit and fix the moved positioning component 300. Furthermore, by rotating the adjusting handwheel 303, the screw 301 is driven to move up and down along the connecting seat 203, thereby driving the drill rod 302 to move up and down, so that the drill rod 302 contacts the ground and drills out the pile position on the ground, thereby completing the selection of the pile position.

[0034] In this invention, by incorporating an extrusion block 74, during construction, the mounting plate 51 can be moved downwards so that the bottom ends of the mixing rod 59 and the grouting pipe 4 reach the bottom of the pit, thereby allowing the sliding block 73 to contact the bottom surface of the toothed ring 55. The second threaded rod 75 is rotated to move the extrusion block 74, thus fixing the sliding block 73. When the mounting plate 51 moves the mixing rod 59 downwards, the sliding block 73 and the extrusion block 74 prevent the mixing rod 59 from contacting the bottom of the pit and impacting it. This design limits the range of vertical movement of the mounting plate 51 during construction, preventing the mixing rod 59 and the grouting pipe 4 from contacting or detaching from the pit, thus avoiding any impact on the pit and the subway tunnel.
