Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic support foundations, and in particular to a steel cage positioning device for the construction of a large-slope photovoltaic support pile foundation. Background Art

[0002] Concrete bored piles are often used for the foundation of photovoltaic bracket piles. The construction process of concrete bored piles mainly includes drilling, placing steel cages and pouring concrete. Mountain photovoltaics are limited by the terrain and the site slope is large. The average slope is usually 30°~35°, and it can reach 45° locally. Since the length of concrete bored piles is long (usually about 3 meters), during the placement of the steel cage, there is a gap between the steel cage and the inner wall of the pile hole, and it is difficult for the steel cage to be concentric with the pile hole after placement. At the same time, during the pouring of concrete, the steel cage is easily displaced by impact, causing the steel cage and the pile hole to be non-concentric. After the concrete is poured, the embedded parts or steel brackets connected to the steel cage deviate from the center of the pile hole, causing the photovoltaic bracket columns to deviate after installation. It is difficult for adjacent photovoltaic brackets to form a whole and installation is difficult. At the same time, the deflection of the steel cage can easily cause the concrete retaining wall layer outside the steel cage, embedded parts or steel bracket to be uneven in thickness and leak reinforcement, thereby reducing the strength of the concrete pile foundation. Utility Model Content

[0003] The main purpose of the utility model is to provide a steel cage positioning device for the construction of photovoltaic bracket pile foundation with a large slope, which is used to solve the problem that the steel cage is easily deflected during the pouring of existing photovoltaic bracket concrete piles, thereby causing missing bars, uneven protective layer thickness, and deflection of the bracket foundation or embedded parts.

[0004] To achieve the above purpose, the utility model provides a steel cage positioning device for large-slope photovoltaic support pile foundation construction, comprising:

[0005] The positioning assembly includes a bottom sleeve and a top sleeve slidably disposed in the bottom sleeve; the bottom sleeve is detachably provided with a lifting rod; the lifting rod is provided with a handle, and the lifting rod is detachably connected to the top sleeve;

[0006] The support assembly includes a plurality of support rods movably arranged at intervals on the outer wall of the top sleeve, and locking members arranged on the support rods; the locking members are inserted into the soil layer under the action of external force, thereby fixing the positions of the support rods and the top sleeve;

[0007] The limiting assembly includes multiple groups of adjusting parts movably arranged on the top sleeve and a limiting plate arranged in the top sleeve and connected to the adjusting parts; the adjusting parts are provided with scales, and the adjusting parts move toward or away from the center of the top sleeve under the action of external force, thereby adjusting the position of the limiting plate in the top sleeve.

[0008] As a further improvement of the present invention, a section of the top sleeve away from the support rod is interactively nested in the bottom sleeve, the top sleeve and the bottom sleeve are clearance-matched, and the outer diameter of the top sleeve is smaller than the inner diameter of the bottom sleeve.

[0009] As a further improvement of the present invention, a first fixing piece is provided on the outer wall of the top sleeve; the first fixing piece and the support rod are arranged alternately; a second fixing piece connected to the first fixing piece is provided on the end of the lifting rod away from the bottom sleeve.

[0010] As a further improvement of the present invention, a first ear plate is provided on the top sleeve; and the support rod is rotatably connected to the first ear plate.

[0011] As a further improvement of the present invention, the adjusting part includes adjusting screws that are equidistant and spaced apart; the adjusting screws are connected to the top sleeve through threads, and the adjusting screws are spaced apart on the top sleeve in two layers; the scale is set on the adjusting screw; and the limit plate is connected to the adjusting screw.

[0012] The beneficial effects of the present invention are as follows:

[0013] By arranging top sleeves and bottom sleeves that are nested with each other, the overall size can be shortened, and the steel cage in the pile hole can be positioned in sections. After adjusting the top sleeve to be concentric with the pile hole, the position of the top sleeve is fixed by the support rod and the locking piece, and then the steel cage and the top sleeve are fixed concentrically with the adjusting piece and the limit plate, so that the steel cage and the pile hole are concentric. During the pouring of concrete, the steel cage will not deflect. When taking out the device, first move up the bottom sleeve so that the lower part of the steel cage is limited by the concrete, and then move up the top sleeve, so that the steel cage will not be displaced when taking out the device.

It should be understood that the embodiments described are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] In one embodiment, see Figure 1 、 2 , 3, 4, 5, the utility model is a steel cage positioning device for the construction of a large-slope photovoltaic support pile foundation, including a positioning component, a support component, and a limit component.

[0024] Among them, the positioning assembly includes a bottom sleeve 1, a top sleeve 2 slidingly arranged in the bottom sleeve 1, a lifting rod 3 is detachably provided on the bottom sleeve 1, a lifting handle 4 is provided on the lifting rod 3, and the lifting rod 3 is detachably connected to the top sleeve 2; the support assembly includes multiple groups of support rods 5 that are spaced and movably arranged on the outer wall of the top sleeve 2, and a locking piece 6 arranged on the support rod 5. The locking piece 6 is inserted into the soil layer under the action of external force, thereby fixing the position of the support rod 5 and the top sleeve 2; the limiting assembly includes multiple groups of adjusting parts 7 that are movably arranged on the top sleeve 2, and a limiting plate 8 that is arranged in the top sleeve 2 and connected to the adjusting part 7. The adjusting part 7 is provided with a scale 9. The adjusting part 7 moves toward or away from the center of the top sleeve 2 under the action of external force, thereby adjusting the position of the limiting plate 8 in the top sleeve 2.

[0025] For further information, see Figure 1 A section of the top sleeve 2 away from the support rod 5 is interactively nested in the bottom sleeve 1 , the top sleeve 2 and the bottom sleeve 1 are clearance-matched, and the outer diameter of the top sleeve 2 is smaller than the inner diameter of the bottom sleeve 1 .

[0026] Preferably, the top sleeve 2 and the bottom sleeve 1 are both hollow cylinders with openings at both ends.

[0027] Preferably, the support rod 5 is provided on an end of the top sleeve 2 away from the bottom sleeve 1 .

[0028] In the above setting, the top sleeve 2 can be slidably inserted into the bottom sleeve 1 until the support rod 5 abuts against the bottom sleeve 1, thereby reducing the overall length, and the lifting rod 3 can be flipped over and attached to the outer wall of the bottom sleeve 1, also reducing the overall length; when in use, the lifting rod 3 is flipped over and positioned above the bottom sleeve 1 and close to the top sleeve 2. At this time, the lifting rod 3 exceeds the top sleeve 2, and the bottom sleeve 1 is moved down into the cavity until the lifting handle 4 is connected to the top sleeve 2.

[0029] For further information, see Figure 1 、 2 3. A first fixing member 10 is provided on the outer wall of the top sleeve 2, and the first fixing member 10 is staggered with the support rod 5; a second fixing member 11 connected to the first fixing member 10 is provided on the end of the lifting rod 3 away from the bottom sleeve 1.

[0030] Preferably, the first fixing member 10 is a first fixing block 1001 provided on the top sleeve 2 . The first fixing blocks 1001 are symmetrically provided in two groups. The first fixing blocks 1001 are provided with fixing holes 1002 .

[0031] Preferably, the second fixing member 11 is a fixing plate 1101 arranged on the lifting rod 3, the lifting handle 4 is arranged on the fixing plate 1101, the lifting rod 3 is clearance-matched with the first fixing block 1001 toward the inner wall of the top sleeve 2, and a connecting screw hole 12 is provided on the bottom sleeve 1, and the lifting rod 3 is connected to the connecting screw hole 12 through a thread.

[0032] In the above arrangement, after the lifting rod 3 is connected to the connecting screw hole 12 through a thread, the bottom sleeve 1 is slid away from the top sleeve 2, and the fixing plate 1101 moves toward and abuts against the first fixing block 1001, and the relative positions of the bottom sleeve 1 and the top sleeve 2 are fixed.

[0033] For further information, see Figure 3 A first ear plate 13 is provided on the top sleeve 2, and the support rod 5 is rotatably connected to the first ear plate 13.

[0034] Preferably, four groups of first ear plates 13 are provided, and the four groups of first ear plates 13 are equidistantly arranged on the top sleeve 2 along the circumferential direction. A first rotating hole 14 is provided on the first ear plate 13, and a first rotating shaft 15 is provided on the support rod 5. The first rotating shaft 15 is rotatably connected to the first rotating hole 14.

[0035] Preferably, a support block 16 is provided on the support rod 5 , a hole 17 is provided on the support block 16 , and the locking member 6 includes a locking rod 601 , which passes through the hole 17 and is inserted into the soil layer.

[0036] In the above setting, the angle of the support rod 5 relative to the top sleeve 2 can be adjusted by rotating the support rod 5. After the four groups of support rods 5 are unfolded, they are supported on the ground, and the top sleeve 2 is adjusted to be concentric with the pile hole of the photovoltaic bracket pile foundation through equipment such as a level. Then, the locking rod 601 is used to pass through the hole and inserted into the soil layer to fix the position of the top sleeve 2. At this time, the bottom sleeve 1 is connected to the top sleeve 2 through the lifting rod 3, and the position of the bottom sleeve 1 is also fixed.

[0037] For further information, see Figure 1 、 6 The adjusting member 7 includes adjusting screws 701 that are equidistant and spaced apart. The adjusting screws 701 are connected to the top sleeve 2 through threads. The adjusting screws 701 are spaced apart on the top sleeve 2 in two layers, the scale 9 is set on the adjusting screw 701, and the limit plate 8 is connected to the adjusting screw 701.

[0038] Preferably, four groups of adjusting screws 701 are provided, and the adjusting screws 701 are arranged in groups of two and staggered, and the axes of the adjusting screws 701 in the same group are located on the same straight line; the top sleeve 2 is provided with a mounting screw hole 18.

[0039] In the above setting, by rotating the adjusting screw 701, the adjusting screw 701 is moved toward or away from the center of the top sleeve 2 under the action of the thread, and the distance moved by the adjusting screw 701 is identified by the scale 9, so that the position of the limit plate 8 in the top sleeve 2 can be determined. After the steel cage is placed in the top sleeve 2, the limit plate 8 can be used to fix the position of the steel cage, and the steel cage is located in the center of the top sleeve 2. The distance between the outer wall of the steel cage and the inner wall of the top sleeve 2 is consistent. Under the push of the upper and lower sets of adjusting screws 701, the upper and lower sets of limit plates 8 fix the upper and lower positions of the steel cage, thereby providing stable limitation so that the steel cage will not swing.

[0040] After the adjustment is completed, the steel cage is placed, and the four sets of adjusting screws 701 are rotated so that the four sets of limit plates 8 move the same distance and abut against the outer wall of the steel cage. The distances between the four groups of limit plates 8 and the center of the top sleeve 2 are equal, ensuring that the steel cage is concentric with the top sleeve 2, and then the concrete can be poured and vibrated. After the vibration is completed, the lifting handle 4 is moved up first to drive the lifting rod 3 and the bottom sleeve 1 to move up. At this time, the upper half of the steel cage is fixed by the limit plates 8 and concrete, and the lower half is fixed by concrete. During the upward movement of the bottom sleeve 1, the position of the steel cage remains unchanged. When the bottom sleeve 1 is completely moved up to abut against the first ear plate 13, the lower half of the steel cage is fixed by concrete. At this time, the adjusting screw 701 can be rotated in the opposite direction to drive the limit plates 8 to move away from the steel cage, take out the locking rod 601, move the top sleeve 2 up, and move the top sleeve 2 out of the pile hole. During the movement of the top sleeve 2, the steel cage is limited entirely by the concrete, which can ensure that the steel cage does not deflect during the concrete pouring process.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
