Description

Technical Field

[0001] The technical field related to the present utility model especially relates to a construction positioning device for a photovoltaic pile foundation. Background Art

[0002] With the development of technology, the utilization rate of green energy technology is getting higher and higher, especially the way of using photovoltaic panels to utilize solar energy is increasing.

[0003] When installing photovoltaic panels, it is necessary to first install the photovoltaic pile foundation, that is, the positioning installation of photovoltaic piles, then install the photovoltaic bracket, and finally install the photovoltaic panels on the photovoltaic bracket. When installing the photovoltaic piles, it is necessary to first drill holes and then drive the photovoltaic piles into the holes. Among them, since the shape and size of the photovoltaic panels are determined, in order to ensure that the photovoltaic panels will not be mismatched with the photovoltaic brackets during installation, it is necessary to ensure the perpendicularity of the photovoltaic piles during installation, so as to avoid the situation where the connection position between the photovoltaic panels and the photovoltaic piles cannot be adapted due to the inclination of the photovoltaic piles.

[0004] In the prior art, a Chinese patent with the application number CN202222786246.9 discloses a construction positioning device for a photovoltaic pile foundation, which includes a first support plate. Both ends of the first support plate are fixed with sliding cylinders. A first fixed rod is slidably connected to the sliding cylinders. A second support plate is fixed on the first fixed rod. A spring is fixed on the sliding cylinder. A positioning device is arranged on the first fixed rod and is connected to the spring. A drilling device is arranged on the first support plate, and an adjusting mechanism is arranged on the second support plate. This device drives the support plate to press down through the adjusting mechanism. When the first support plate is pressed down, it will slide up and down on the fixed rod through the sliding cylinder, and at the same time, the spring will be squeezed. When pressing down, it will drive the drilling device to press down synchronously, and then the fixing device also fixes the main body of the whole device to prevent the device from shifting during drilling, so that the drilling can be more accurate, and then ensure the perpendicularity of the photovoltaic pile when it is driven in. However, when drilling the photovoltaic pile, there are still some problems that need to be improved:

[0005] 1. When installing photovoltaic panels, the above device can only ensure the perpendicularity of the photovoltaic panels and cannot ensure that the distance between each photovoltaic pile is fixed, resulting in an error in the distance between the photovoltaic piles. As a result, when installing the photovoltaic panels later, it is difficult to accurately fix fixing parts such as bolts on the photovoltaic piles. Therefore, it is necessary to manually confirm the drilling positions in advance to ensure that the distance between the photovoltaic piles is fixed and adapted to the size of the photovoltaic panels.

[0006] 2. After manually confirming the drilling positions, when drilling, it is also necessary to manually align the drilling equipment with the previously confirmed drilling points to ensure the accuracy of the drilling positions, so it will take more time, and thus the drilling efficiency is low and not convenient.

[0007] Therefore, there is an urgent need for a construction positioning device for photovoltaic pile foundations, which can make the position of the photovoltaic pile drilling more accurate and the drilling efficiency higher. Summary of the Invention

[0045] Embodiment 1

[0046] It should be understood that when installing the photovoltaic panels, if it is impossible to ensure that the distance between each photovoltaic pile is fixed, the distance between the photovoltaic piles will have an error, resulting in difficulties in accurately fixing fixing parts such as bolts 7 on the photovoltaic piles during the subsequent installation of the photovoltaic panels. Therefore, it is necessary to manually confirm the punching positions in advance to ensure that the spacing between the photovoltaic piles is fixed and adapted to the size of the photovoltaic panels. However, after manually confirming the punching positions, when punching, it is also necessary to manually align the punching device with the previously confirmed punching points to ensure the accuracy of the punching positions. Therefore, it will consume more time, and thus the punching efficiency is low and not convenient.

[0047] Therefore, to improve the above problems, this embodiment provides a construction positioning device for a photovoltaic pile foundation, which mainly includes two collar rings 1, two drilling machines 2, a connecting rod 4, and multiple lifting columns 3. This device is mainly used to accurately position the photovoltaic pile during drilling.

[0048] Among them, as Figure 1 and Figure 4 shown, both of the two collar rings 1 are provided with a ring groove 111 and a guiding groove 112. Among them, the collar ring 1 adopts a cylindrical structure with a cylindrical hollow in the center, so as to reduce the weight of the collar ring 1.

[0049] In this embodiment, as Figure 1 , Figure 4 and Figure 6 shown, the ring groove 111 is continuously arranged along the circumferential direction of the collar ring 1. The ring groove 111 is arranged between the upper side wall and the lower side wall of the collar ring 1. The guiding groove 112 is arranged on the upper side of the collar ring 1, and one notch of the guiding groove 112 communicates with the ring groove 111, and the other notch of the guiding groove 112 communicates with the external space.

[0050] Among them, as Figure 1 shown, the circumferential outer edge of the upper side surface of the collar ring 1 is provided with a circumferential angle scale line 113, and the adjacent scale lines are spaced at an angular degree. Specifically, the degree size between adjacent scale lines can be set according to the minimum rotation angle of the connecting rod 4.

[0051] As Figures 1 - 3 shown, the two drilling machines 2 are respectively detachably connected to the two collar rings 1. Among them, the top end of the drilling machine 2 is arranged along the axial direction of the collar ring 1 on the circumferential side wall inside the collar ring 1. Specifically, the drilling machine 2 and the collar ring 1 can adopt detachable connection methods such as clamping and threaded connection, so that the drilling machine 2 can be detached. Furthermore, different models of drilling machines 2 can be replaced to adapt to the hardness of different drilling surfaces or drilling requirements. At the same time, the drilling machine 2 can also be replaced and repaired by disassembling, improving the maintenance efficiency.

[0052] As Figures 1 - 3 shown, multiple lifting columns 3 are respectively and evenly arranged on the lower side walls of the two collar rings 1, and the multiple lifting columns 3 are sequentially spaced along the circumferential direction of the lower surface of the collar ring 1, so as to stably support the half collar ring 11. At the same time, the drilling depth can be controlled by the rising and falling of the lifting columns 3, and the levelness of the collar ring 1 can also be adjusted by the lifting function of the lifting columns 3. Furthermore, the collar ring 1 is in a horizontal state, so that the drilling machine 2 is in a horizontal state, and then the perpendicularity of the hole during drilling on a horizontal ground is ensured.

[0053] Among them, the lifting column 3 can adopt structures such as a hydraulic cylinder, an electric push rod or a telescopic rod.

[0054] In this embodiment, as Figure 1 ,Figure 4 and Figure 6 As shown in Figure 6 , both ends of the connecting rod 4 pass through the circumferential side walls of the collar 1 respectively and are arranged in the annular groove 111. Indicator blocks 41 are provided on the upper surfaces of both ends of the connecting rod 4. The indicator blocks 41 extend along the guiding groove 112 to the outside of the guiding groove 112 and are arranged above the guiding groove 112. One end of the indicator block 41 points to one of the scale lines of the circumferential angle scale line 113. Among them, the two ends of the connecting rod 4 are adapted to the shapes of the annular groove 111 and the guiding groove 112 and have a small gap therebetween, so that the two ends of the connecting rod 4 can rotate relative to the collar 1 along the annular groove 111 respectively, driving the indicator blocks 41 to rotate along the guiding groove 112 on the upper surface of the collar 1, so that the indicator blocks 41 can point to different scale lines of the circumferential angle scale line 113, thereby confirming the rotation angle of the connecting rod 4.

[0055] In this embodiment, when punching is required, first determine the initial punching position, place the device at this position on the horizontal ground. Then, raise the lifting column 3 to a specified height, thereby driving the collar 1 and the punching machine 2 to rise to the specified height, so that the punching machine 2 is higher than the horizontal ground or abuts against the horizontal ground. After that, start the punching machine 2 to make the punching machine 2 rotate, and then lower the lifting column 3 by a specified height, so that the punching machine 2 punches holes. After the punching is completed, raise the lifting column 3, and then the punching machine 2 disengages from the hole. Then, taking one of the collars 1 as a reference, rotate the other collar 1. Due to the connection of the connecting rod 4, the other collar 1 rotates relative to the reference collar 1, and through the scale of the indicator block 41 and the circumferential angle scale line 113, the rotation angle of the other collar 1 is judged, so that the other collar 1 accurately rotates to the next punching position, and the punching machine 2 is aligned with the punching position. At this time, taking the rotated collar 1 as a reference, rotate the previously used reference collar 1 by a specified degree, so that the previously used reference collar 1 rotates to the specified position. After that, repeat the above punching operation, and the punching position can be relatively accurate. Moreover, since this device is used for auxiliary positioning and two positions are punched simultaneously, the alignment time between the punching machine 2 and the punching position is less, and the punching efficiency is improved.

[0056] Among them, the rotation angle of the collar 1 can be selected according to the punching position.

[0057] Among them, after the punching position is determined manually in advance, this device can be used to assist the punching machine 2 to align with the punching position, so as to ensure that the punching position is relatively accurate and improve the punching efficiency.

[0058] In this embodiment, the punching machine 2 is a prior art and will not be elaborated here.

[0059] In some embodiments, such as Figures 1 - 3As shown, the collar 1 includes two connected half-collars 11. The half-collars 11 adopt a semi-circular structure. The two half-collars 11 are connected to form a collar 1. Specifically, when the two half-collars 11 are connected to form the collar 1, the end faces of the two half-collars 11 are in contact with each other, so that the two half-collars 11 form the collar 1.

[0060] As Figures 1 - 3 shown, connectors 12 are provided at both ends of the circumferential side wall of the half-collar 11. The two half-collars 11 are detachably connected by four connectors 12, so that the connection and disconnection of the two half-collars 11 are relatively simple. Thus, the connectors 12 can be replaced or repaired by disassembly, making the replacement and repair of the connectors 12 relatively simple.

[0061] In this embodiment, as Figure 1 、 Figure 3 and Figure 4 shown, the two half-collars 11 are provided with annular grooves 111 and guide grooves 112. When the two half-collars 11 are connected, the two annular grooves 111 communicate with each other, and the two guide grooves 112 communicate with each other. One end of the connecting rod 4 is arranged in the annular groove 111 of one of the half-collars 11. A plurality of lifting columns 3 are arranged at intervals on the lower side wall of the half-collar 11. The top end of the punching machine 2 is detachably connected to the two half-collars 11 of the same collar 1. Specifically, the outer wall of the circumference of the top end of the punching machine 2 is detachably connected to the outer wall of the inner circumference of the two half-collars 11, so that the installation of the punching machine 2 is stable.

[0062] Among them, when installing the punching machine 2, first connect and fit the outer wall of the circumference of the top end of the punching machine 2 with the outer wall of the inner circumference of the half-collar 11, and then fit and connect the outer wall of the inner circumference of the other half-collar 11 with the outer wall of the circumference of the top end of the punching machine 2. At the same time, connect the two half-collars 11, so as to further make the connection between the punching machine 2 and the half-collar 11 stable, and the installation of the punching machine 2 is relatively simple.

[0063] In this embodiment, as Figures 1 - 3 shown, in order to make the connection between the two half-collars 11 stable and not hinder the rotation of the connecting rod 4 relative to the collar 1, the connector 12 includes two connecting blocks 121. The two connecting blocks 121 are arranged at intervals along the axial direction of the half-collar 11. The distance between the two connecting blocks 121 is greater than the dimension of the connecting rod 4 along the axial direction of the half-collar 11, so that when the connecting rod 4 rotates, it can rotate through the gap between the two connecting blocks 121, and thus while ensuring the stable connection of the two half-collars 11, it will not affect the rotation of the connecting rod 4.

[0064] In some embodiments, as Figure 1 、 Figure 4 and Figure 7As shown, the device further includes a fixed cover 5. The fixed cover 5 has a top plate 51 and two side plates 52. The two side plates 52 are respectively connected to both ends of the top plate 51. Specifically, the fixed cover 5 adopts a U-shaped structure. The fixed cover 5 is detachably connected to the indicating block 41. When the fixed cover 5 is connected to the indicating block 41, the inner side of the top plate 51 fits and abuts against the upper side of the indicating block 41, and both side plates 52 fit and abut against the upper surface of the half rings 11 on both sides of the notch of the guiding groove 112, thereby fixing the connecting rod 4. Thus, when the device drills a hole, the position of the connecting rod 4 is stable.

[0065] Among them, as Figure 4 and Figure 7 shown, the fixed cover 5 and the indicating block 41 can adopt detachable connection methods such as bolt connection, snap connection or plug connection. In this embodiment, the fixed cover 5 and the indicating block 41 adopt bolt connection. Specifically, when the fixed cover 5 is connected to the indicating block 41, the bolt 7 passes through the top plate 51 of the fixed cover 5 and is connected to the top of the indicating block 41, so that both side plates 52 abut against the upper surface of the half ring 11, thereby fixing the connecting rod 4.

[0066] In some embodiments, as Figure 1 and Figure 6 shown, the connecting rod 4 can adopt structures such as a double-acting hydraulic cylinder, a double-acting electric push rod or a double-acting telescopic rod. Specifically, a driving end 44 is provided in the middle of the connecting rod 4, thereby driving the rod body of the connecting rod 4 to extend or shorten. Thus, the device can drill holes at positions with different length distances by controlling the length of the connecting rod 4.

[0067] Among them, as Figure 6 shown, a horizontal dimension line 42 is provided on the rod body of the connecting rod 4, so that the extension or shortening length of the connecting rod 4 is controllable, and thus holes can be accurately drilled at positions with different length distances.

[0068] In some embodiments, as Figure 1 and Figure 4 shown, two limiting ring grooves 114 are provided on the upper inner wall of the ring groove 111. The two limiting ring grooves 114 are respectively arranged on both sides of the guiding groove 112 along the radial direction of the half ring 11. Two limiting bumps 43 are respectively provided at both ends of the connecting rod 4. The two limiting bumps 43 are respectively arranged in the two limiting ring grooves 114. Among them, the connecting rod 4 can drive the two limiting bumps 43 to slide along the limiting ring grooves 114, so that the direction of the connecting rod 4 is stable when it rotates, avoiding a large change in the rotation trajectory of the connecting rod 4, and thus causing a large deviation in the rotation angle of the connecting rod 4, which in turn affects the accuracy of the drilling position.

[0069] In this embodiment, as Figure 1 、 Figure 4 and Figure 5As shown, a plurality of balls 6 are provided on the inner wall of the lower side of the annular groove 111 and the inner wall of the upper side of the two limiting annular grooves 114. The plurality of balls 6 are arranged at intervals in the circumferential and radial directions of the half sleeve ring 11. Among them, the balls 6 can rotate relative to the annular groove 111 and the limiting annular groove 114, and the plurality of balls 6 respectively abut against the upper surface and the lower surface of the connecting rod 4, so that the resistance received when the connecting rod 4 rotates is small, and thus the rotation of the connecting rod 4 is relatively simple.
