[0018] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention, rather than to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0019] like Figure 1 As shown, the present invention provides an embedded part fixing device, which includes a pile body forming cylinder 1 and an embedded part fixing mechanism 2. The pile body forming cylinder 1 is configured to be cylindrical and is used to be installed at the opening of a pile pit. The embedded part fixing mechanism 2 includes a base 21 and a plurality of positioning mechanisms 22, the base 21 is detachably mounted on the top of the pile body forming cylinder 1, all the positioning mechanisms 22 are circumferentially spaced around the axis of the pile body forming cylinder 1, the positioning mechanisms 22 are adjustable in position on the base 21, and the positioning mechanisms 22 are configured to be connected to the top of the embedded part.

[0020] Specifically, the pile body forming tube 1 is first installed at the opening of the pile pit so that the pile body forming tube 1 surrounds the opening of the pile pit, and then the steel cage with embedded parts is placed in the pile pit, and then the base 21 is installed on the top of the pile body forming tube 1, and then the positions of all positioning mechanisms 22 are adjusted to adapt to the positions of all embedded parts, and then all embedded parts can be fixed to all positioning mechanisms 22 one by one, and then the positioning mechanisms 22 are fixed to the base 21, so that the embedded parts are firmly fixed to the embedded part fixing device. Since the embedded parts are firmly fixed to the embedded part fixing device, even if the concrete in the pouring process will impact the embedded parts or the vibration of the vibration is transmitted to the embedded parts, the preset height, preset orientation and preset inclination of the embedded parts are difficult to change, so that the flexible photovoltaic bracket can be accurately installed, thereby avoiding the reconstruction of concrete piles and reducing construction costs.

[0021] like Figure 1 As shown, in some embodiments of the present invention, the base 21 includes a cylindrical first mounting portion 211 and a cylindrical second mounting portion 212, the first mounting portion 211 circumferentially surrounds the top of the pile body forming cylinder 1, the bottom of the second mounting portion 212 is fixedly connected to the top of the first mounting portion 211, the second mounting portion 212 is located above the pile body forming cylinder 1, the axis of the first mounting portion 211, the axis of the second mounting portion 212 and the axis of the pile body forming cylinder 1 coincide, the inner and outer diameters of the second mounting portion 212 are respectively equal to the inner and outer diameters of the pile body forming cylinder 1, and the positioning mechanism 22 is installed on the second mounting portion 212.

[0022] Specifically, the base 21 is set to the above-mentioned shape structure, which is simple in structure and convenient to cooperate with the pile body forming cylinder 1. When manufacturing a concrete pile, the pile body forming cylinder 1 is placed and fixed on the ground and surrounds the opening of the pile pit, and then the base 21 is installed on the top of the pile body forming cylinder 1. After the base 21 is installed, the first installation part 211 is sleeved on the outside of the top of the pile body forming cylinder 1, and the bottom of the second installation part 212 is in contact with the top of the first installation part 211. Based on the gravity of the base 21 and the positioning mechanism 22, the base 21 is difficult to move.

[0023] In some embodiments, the base 21 may also be a U-shaped or L-shaped plate, etc., and the present invention is not limited thereto, as long as the above technical effects can be achieved. In some embodiments, the base 21 may also be a square cylinder, and the base 21 and the pile forming cylinder 1 may be connected by a flange.

[0024] like Figure 5 As shown, in some embodiments of the present invention, a first connecting plate 213 is provided on the outer wall of the first mounting portion 211, and a second connecting plate 214 is provided on the outer wall of the pile body forming cylinder 1. The first connecting plate 213 and the second connecting plate 214 are fitted together, and the first connecting plate 213 and the second connecting plate 214 are connected by a first bolt and nut assembly 215.

[0025] Specifically, the first connecting plate 213 and the second connecting plate 214 are fitted with each other. The first bolt and nut assembly 215 includes a first bolt and a first nut. The screw of the first bolt vertically passes through the first connecting plate 213 and the second connecting plate 214, the head of the first bolt is located above the first connecting plate 213 and the second connecting plate 214, the first nut is threadedly connected to the screw of the first bolt, and the first nut is located below the first connecting plate 213 and the second connecting plate 214. The base 21 and the pile body forming cylinder 1 can be fixed by the first bolt and nut assembly 215 to prevent relative movement between the base 21 and the pile body forming cylinder 1.

[0026] Of course, the first connecting plate 213 and the second connecting plate 214 may not be provided, and the base 21 may be kept stable only by its own gravity.

[0027] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the second mounting portion 212 is provided with a plurality of adjustment long holes 216 spaced apart along the circumference thereof, and the adjustment long holes 216 extend along the circumference of the second mounting portion 212, and the adjustment long holes 216 penetrate the second mounting portion 212 in the radial direction of the second mounting portion 212. All positioning mechanisms 22 are respectively mounted at all adjustment long holes 216 in a one-to-one correspondence through a pair of second bolt and nut assemblies 23. Based on the loosening or tightening of the second bolt and nut assemblies 23, the positioning mechanism 22 can move along the corresponding adjustment long hole 216 or be fixed at the adjustment long hole 216.

[0028] Specifically, the positioning mechanism 22 is installed at the adjusting slot 216 through a pair of second bolt and nut assemblies 23. By loosening the second bolt and nut assemblies 23, the position of the positioning mechanism 22 can be adjusted along the adjusting slot 216 so that the positioning mechanism 22 can adapt to the position of the embedded part; by tightening the second bolt and nut assemblies 23, the positioning mechanism 22 is fixed at the adjusting position of the adjusting slot 216 so that the positioning mechanism 22 can adapt to the position of the embedded part. In addition, the length of the adjusting slot 216 is along the circumference of the second mounting portion 212, and the width of the adjusting slot 216 is along the vertical direction, so that the second bolt and nut assemblies 23 can adapt to the width of the adjusting slot 216.

[0029] like Figure 2 , Figure 3 and Figure 4As shown, in some embodiments of the present invention, the positioning mechanism 22 includes a mounting seat 221, a first connecting rod 222, a second connecting rod 223 and a positioning bolt 224. The mounting seat 221 is attached to the outer wall of the second mounting portion 212, the first connecting rod 222 passes through the mounting seat 221 and the corresponding adjustment slot 216 along the radial direction of the second mounting portion 212, the head end of the first connecting rod 222 is located at the radial outer side of the second mounting portion 212, and the end of the first connecting rod 222 is located at the radial inner side of the second mounting portion 212. The positioning bolt 224 is threadedly connected to the mounting seat 221, the bottom end of the screw of the positioning bolt 224 can press against the side of the first connecting rod 222, and the head of the positioning bolt 224 is spaced apart from the mounting seat 221; the head end of the second connecting rod 223 is vertically rotatably connected to the end of the first connecting rod 222, and the end of the second connecting rod 223 is provided with a clamping structure for clamping the top of the embedded part. The second bolt and nut assembly 23 includes a second bolt and a second nut. The screw rod of the second bolt passes through the mounting seat 221 and the corresponding adjustment long hole 216. The mounting seat 221 is located between the second mounting portion 212 and the head of the second bolt. The second nut is threadedly connected to the screw rod of the second bolt. The second nut is located on the radial inner side of the second mounting portion 212. The second nut and the head of the second bolt can clamp the mounting seat 221 at the corresponding adjustment long hole 216.

[0030] Specifically, the second nut is rotated to make the second nut away from the inner wall of the second mounting portion 212, the second bolt and nut assembly 23 is loosened, and then the position of the mounting seat 221 is adjusted along the adjusting slot 216 so that the position of the mounting seat 221 is adapted to the position of the embedded part; the second nut is rotated in the opposite direction, the second bolt and nut assembly 23 is tightened, and the second nut and the head of the second bolt clamp the mounting seat 221 to the outer wall of the second mounting portion 212, and the mounting seat 221 is fixed in the new position. In addition, the length and width of the second nut are greater than the width of the adjusting slot 216, the vertical width of the mounting seat 221 is also greater than the width of the adjusting slot 216, and the diameter of the first connecting rod 222 and the screw of the second bolt are slightly smaller than the width of the adjusting slot 216.

[0031] In other embodiments, the positioning mechanism 22 may also be in other structural forms, which are not limited by the present invention. For example, the positioning mechanism 22 includes a pair of parallel and spaced connecting cross bars, which are detachably connected to the top of the second mounting portion 212, and the position of the connecting cross bars is adjustable, and the top of the embedded part can be tied to the connecting cross bars to fix the embedded part.

[0032] like Figure 3 and Figure 4As shown, in some embodiments of the present invention, the mounting seat 221 includes a first mounting block 225, two second mounting blocks 226 and two third mounting blocks 227. The third mounting block 227 is fitted with the outer wall of the second mounting portion 212, and the two third mounting blocks 227 are spaced apart in the circumferential direction of the second mounting portion 212. The two ends of the first mounting block 225 are fixedly connected to the two third mounting blocks 227 through the two second mounting blocks 226, respectively, and the two second mounting blocks 226 are spaced apart in the circumferential direction of the second mounting portion 212. The first connecting rod 222 movably passes through the first mounting block 225 and the corresponding adjustment slot 216, and the first connecting rod 222 is located between the two second mounting blocks 226 and between the two third mounting blocks 227. The screw of the positioning bolt 224 is threadedly connected to the top of the first mounting block 225, and the bottom end of the screw of the positioning bolt 224 can press against the side of the first connecting rod 222. The head of the positioning bolt 224 is located above the first mounting block 225 and is spaced apart.

[0033] Specifically, on the one hand, the positioning bolt 224 is relatively far from the second mounting portion 212, which facilitates the rotation of the positioning bolt 224. On the other hand, the first mounting block 225 and the second mounting portion 212 are far apart, and the overall center of gravity of the first connecting rod 222 and the second connecting rod 223 will be located between the first mounting block 225 and the second mounting portion 212, and the two can jointly form a stable support for the first connecting rod 222 and the second connecting rod 223, preventing the first connecting rod 222 and the second connecting rod 223 from sliding toward the embedded part or away from the embedded part, thereby preventing the preset height, preset orientation and preset inclination angle of the embedded part from changing due to the sliding of the first connecting rod 222 and the second connecting rod 223.

[0034] like Figure 3 As shown, in some embodiments of the present invention, a guide block 2271 is provided on one side of the third mounting block 227 facing the second mounting portion 212 , and the guide block 2271 is located in the corresponding adjusting slot 216 .

[0035] Specifically, the width of the guide block 2271 is slightly smaller than the width of the adjustment slot 216. Therefore, when the second bolt and nut assembly 23 is loosened, the mounting seat 221 can move in the adjustment slot 216 through the guide block 2271, and the guide block 2271 can clear the concrete in the adjustment slot 216 to a certain extent to prevent the concrete from obstructing the adjustment of the first connecting rod 222; and the guide block 2271 can also keep the second bolt and nut assembly 23, the mounting seat 221 and the first connecting rod 222 at a stable height, which helps to simplify the operation process of the embedded part fixing device.

[0036] like Figure 4As shown, in some embodiments of the present invention, the mounting seat 221 further includes a fourth mounting block 228 , the second mounting block 226 is located between the two second mounting blocks 226 and is fixedly connected to the second mounting block 226 , and the first connecting rod 222 movably passes through the fourth mounting block 228 .

[0037] Specifically, the clamping structure of the second connecting rod 223 is fixed to the top of the embedded part, and then the second connecting rod 223 is fixed to the first connecting rod 222, and the first connecting rod 222 is fixed to the mounting seat 221. Since the fourth mounting block 228 and the first mounting block 225 can support the first connecting rod 222, the first connecting rod 222 is unlikely to be displaced or offset, so that the first connecting rod 222 maintains a stable position and a high stability, which facilitates the fixing of the first connecting rod 222 and prevents the embedded part from being displaced or offset due to the displacement or offset of the first connecting rod 222.

[0038] like Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the clamping structure includes a vertically extending clamping groove 2221 and a horizontally extending clamping bolt 2222. The clamping groove 2221 is provided at the end of the second connecting rod 223 and extends from the top side thereof to the bottom side thereof; the screw of the clamping bolt 2222 is threadedly connected to the horizontal side portion of the end of the second connecting rod 223, the bottom end of the screw of the clamping bolt 2222 can extend into the clamping groove 2221, and the head of the clamping bolt 2222 is located outside the clamping groove 2221.

[0039] Specifically, the top of the embedded part is located in the clamping groove 2221, and then the clamping bolt 2222 is rotated to make the clamping bolt 2222 extend into the clamping groove 2221, and the head of the embedded part is clamped between the bottom end of the screw rod of the clamping bolt 2222 and the groove side wall of the clamping groove 2221; the clamping bolt 2222 is rotated in the opposite direction, and the screw rod of the clamping bolt 2222 is away from the top of the embedded part, and the clamping groove 2221 can be detached from the embedded part.

[0040] In other embodiments, the clamping structure may also be in other structural forms, which are not limited in the present invention. For example, the clamping structure includes a clamp and two clamping plates, the two clamping plates are rotatably connected to the ends of the second connecting rod 223 and are horizontally spaced apart, the two clamping plates can clamp the top of the embedded part, and the clamp can surround the two clamping plates and fix the two clamping plates to fix the embedded part.

[0041] like Figure 3 and Figure 4As shown, in some embodiments of the present invention, the end of the first connecting rod 222 is provided with a connecting groove 2223 extending from the top side thereof to the bottom side thereof, and the head end of the second connecting rod 223 is inserted into the connecting groove 2223. The positioning mechanism 22 also includes a third bolt and nut assembly 2224, and the third bolt and nut assembly 2224 further includes a third bolt and a third nut, the screw rod of the third bolt horizontally passes through the end of the second connecting rod 223, the connecting groove 2223 and the head end of the second connecting rod 223, the third nut is threadedly connected to the screw rod of the third bolt, and the end of the first connecting rod 222 and the head end of the second connecting rod 223 are located between the head of the third bolt and the third nut.

[0042] Specifically, when the third nut is rotated, the head of the third bolt and the third nut move away from each other, the first connecting rod 222 no longer clamps the second connecting rod 223, and the second connecting rod 223 can rotate relative to the first connecting rod 222; when the third nut is rotated in the opposite direction, the head of the third bolt and the third nut move closer to each other, the first connecting rod 222 clamps the second connecting rod 223, and the second connecting rod 223 is fixed to the first connecting rod 222. From another perspective, the end of the second connecting rod 223 has two horizontally spaced clamping blocks, and a clamping groove 2221 is formed between the two clamping blocks, and a screw of the third bolt is threadedly connected to one of the clamping blocks.

[0043] Combine the following Figure 1 The fixing method of the embedded parts is explained again. First, the pile body forming tube 1 is installed at the opening of the pile pit so that the pile body forming tube 1 surrounds the opening of the pile pit, and then the steel cage with the embedded parts is placed in the pile pit, and then the base 21 is installed on the top of the pile body forming tube 1. Then loosen the second bolt and nut assembly 23, and adjust the position of the mounting seat 221 so that the clamping structure adapts to the position of the corresponding embedded part. The clamping structure then clamps the top of the embedded part; then tighten the third bolt and nut assembly 2224; then tighten the second bolt and nut assembly 23 to fix the embedded part to the base 21 and the pile body forming tube 1, that is, to firmly fix the embedded part to the embedded part fixing device.
