Description

Technical Field

[0001] This utility model relates to the field of bolt positioning technology for cast-in-place piles in photovoltaic engineering, and in particular to a foldable and adjustable tool for positioning pre-embedded bolts in cast-in-place piles for photovoltaic engineering. Background Technology

[0002] With the introduction of the national "dual carbon" strategic goal, my country has begun to accelerate the construction of a "new power system with new energy as the main body". The new energy photovoltaic industry has once again achieved a new round of rapid development. As a pillar industry of the new energy cause, photovoltaic engineering is characterized by short construction period, large photovoltaic construction area, large number of pile foundations, and large amount of labor input. In particular, if bored piles are used for the foundation of onshore photovoltaic projects, there will inevitably be a situation of group pile foundation construction.

[0003] Traditional tools for positioning embedded bolts in photovoltaic engineering cast-in-place piles mostly rely on simple wire binding or welding of anchor bolts to structural reinforcement during pile construction. This method often fails to ensure the parallelism and spacing of embedded parts between groups. Consequently, workers need to constantly measure and adjust the angle and spacing of the embedded bolts with a tape measure to ensure the quality of the construction, greatly reducing construction efficiency and resulting in a significant waste of human resources.

[0004] Therefore, regarding the aforementioned traditional photovoltaic engineering cast-in-place pile pre-embedded bolt positioning tools, during the construction of cast-in-place piles, the fixing methods are mostly simple wire binding or welding anchor bolts to structural reinforcement, which makes it difficult to ensure the parallelism and spacing of pre-embedded parts between groups. A new tool can be designed that is simple to manufacture, easy to use, low in cost, and highly applicable to different pile types. This tool can control the parallelism and spacing of pre-embedded parts, eliminating the need for workers to constantly measure and adjust the angle and spacing of the pre-embedded bolts with a tape measure during the work process. This ensures the construction quality of the pre-embedded bolts, significantly increases construction efficiency, and reduces the consumption of human resources. Utility Model Content

[0005] To overcome the limitations of traditional photovoltaic engineering cast-in-place pile pre-embedded bolt positioning tools, the fixing methods during cast-in-place pile construction are mostly simple wire binding or welding anchor bolts to structural reinforcement, which makes it difficult to ensure the parallelism and spacing of pre-embedded parts between groups.

[0009] Preferably, a pin hole is provided at the upper end of the spacing frame, and the pin hole penetrates the spacing frame.

[0010] Preferably, an elevation nut is provided on the outside of the U-bolt, the elevation nut is located at the upper end of the connecting rod, and the U-bolt passes through the pin hole and is connected to the elevation nut.

[0011] Preferably, a steel casing is provided at the lower end of the spacing frame, and the steel casing is located outside the U-bolt.

[0012] Preferably, the spacing nut is located at the upper end of the connecting rod and passes through the connecting rod.

[0013] The beneficial effects of this utility model are:

[0014] The connecting rod is installed via a spacing frame. The connecting rod is extended and folded to assist in adjusting the spacing of the U-bolts. Rotating the crank drives the screw to rotate, which in turn drives the slider. A limiting shaft is installed via a fixing bracket, which restricts the movement of the slider.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment: a foldable and adjustable positioning tool for pre-embedded bolts of photovoltaic engineering cast-in-place piles, including a U-bolt 1, a spacing frame 5, and a fixing component; the U-bolt 1 is provided with a spacing frame 5 on its outer side, the spacing frame 5 is provided with two sets, a connecting rod 3 is provided on one side of the spacing frame 5, a screw 902 is provided above the spacing frame 5, a crank handle 901 is provided on one side of the screw 902, a fixing frame 903 is provided on the outer side of the screw 902, a limiting shaft 904 is provided on one side of the fixing frame 903, the surface of the limiting shaft 904 is provided with a scale, a slider 905 is provided on the outer side of the screw 902, the slider 905 is located at the upper end of the spacing frame 5, the limiting shaft 904 passes through the slider 905, and is installed and connected through the spacing frame 5. The connecting rod 3 extends and folds to assist in adjusting the spacing of the U-bolts 1. Rotating the crank 901 drives the screw 902 to rotate, which in turn drives the slider 905 to move. A limiting shaft 904 is installed on the fixing frame 903, which restricts the movement of the slider 905. The movement of the slider 905 drives the spacing frame 5 to move, which in turn causes the connecting rod 3 to extend or retract. The spacing value can be clearly seen through the scale on the limiting shaft 904. This eliminates the need for workers to constantly measure and adjust the angle and spacing of the embedded bolts during the work process, ensuring the construction quality of the embedded bolts, greatly increasing construction efficiency, and reducing the consumption of human resources.

[0022] Please see Figures 1-4In this embodiment, the fixing component includes a spring 802 and a clamping block 803. A spring 802 is provided inside the slider 905, and two sets of springs 802 are provided. A clamping block 803 is provided on one side of each spring 802. During use, pressing the spacing frame 5 squeezes the clamping block 803, causing the slider 905 to move. The movement of the clamping block 803 drives the spring 802 to extend and retract, storing energy through the extension and retraction of the spring 802. When pressing stops, the spring 802 returns to its original position, fixing the spacing frame 5. This prevents the slider 905 from falling off; the fixing component also includes a fixing pin 801; the fixing pin 801 is provided inside the spring 802, the fixing pin 801 passes through the slider 905, the fixing pin 801 is located on one side of the clamping block 803, and the slider 905 is moved by pulling the fixing pin 801 during use, so that the fixing can be easily removed and the device can be taken off; a pin hole 6 is opened at the upper end of the spacing frame 5, the pin hole 6 passes through the spacing frame 5, and the U-bolt 1 is installed through the pin hole 6 during use, so that the elevation of the U-bolt 1 can be easily adjusted;

[0023] An elevation nut 2 is provided on the outside of the U-bolt 1. The elevation nut 2 is located at the upper end of the connecting rod 3. The U-bolt 1 passes through the pin hole 6 and is connected to the elevation nut 2. In use, the elevation of the two U-bolts 1 in this group is controlled by rotating the control nut, so as to make it easy to adjust the height of the U-bolts 1 to be consistent and to facilitate the recycling of the connecting rod 3. A steel casing 7 is provided at the lower end of the spacing frame 5. The steel casing 7 is located on the outside of the U-bolt 1. In use, the steel casing 7 is used to determine the accurate position of the cast-in-place pile, so as to ensure the accuracy and precision of the construction. The spacing nut 4 is located at the upper end of the connecting rod 3 and passes through the connecting rod 3. In use, the spacing nut 4 is used to assist the connecting rod 3 in extending or retracting. A bolt spacing can be preset in advance to control the parallelism and spacing of the embedded parts.

[0024] During operation, the steel casing 7 is used to determine the accurate position of the cast-in-place pile. The spacing nut 4 is used to extend or retract the auxiliary connecting rod 3, and a bolt spacing can be preset in advance. U-bolts 1 are installed through pin holes 6. The control nut is rotated to control the elevation of the two U-bolts 1 in this group to be consistent. Then, the clamping block 803 is squeezed by pressing the spacing frame 5. The clamping block 803 moves by squeezing the slider 905. The movement of the clamping block 803 drives the spring 802 to extend and retract, storing energy through the extension and retraction of the spring 802. When the pressing stops, the spring 802 returns to its original position, fixing the spacing frame 5. Then, it is fixed by pulling. Pin 801 causes slider 905 to move, making it easy to remove the device by canceling the fixation. Finally, connecting rod 3 is installed through spacing frame 5. The spacing of U bolt 1 is adjusted by folding and extending connecting rod 3. Rotating handle 901 drives screw 902 to rotate. The rotation of screw 902 drives slider 905 to move. Limiting shaft 904 is installed through fixing bracket 903. Limiting shaft 904 restricts the movement of slider 905. The movement of slider 905 drives spacing frame 5 to move. The movement of spacing frame 5 causes connecting rod 3 to extend or retract. The spacing value can be clearly seen through the scale on limiting shaft 904.
