Description

Technical Field

[0001] This invention relates to the field of embedded part positioning device technology, specifically to a pile foundation embedded part positioning device for mountain photovoltaic projects. Background Technology

[0002] With the rapid construction of distributed photovoltaic and mountain photovoltaic projects, a large number of photovoltaic supports need to be installed on base courses with large slopes or uneven soft soil. To ensure the load-bearing stability and array arrangement accuracy of the subsequent supports, high-precision benchmark positioning needs to be completed before pile foundation construction. However, due to the uneven terrain and large differences in soil hardness in mountainous areas, traditional positioning methods mostly rely on simple measuring tools and manual visual inspection. The positioning markers are usually inserted into the foundation by hammering, which is not only labor-intensive but also lacks assistive mechanisms, easily leading to problems such as soil deviation and inaccurate positioning. At the same time, existing positioning devices mostly require manual leveling with the help of external levels and cannot automatically correct their posture according to the slope angle, making it difficult to establish a reliable horizontal reference in a timely manner, resulting in insufficient vertical guidance accuracy of the pile position. Therefore, this application proposes a positioning device for embedded parts of pile foundations in mountain photovoltaic projects. Summary of the Invention

[0003] The purpose of this invention is to provide a positioning device for pre-embedded piles in mountain photovoltaic projects, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a positioning device for embedded piles in a mountain photovoltaic project, comprising a positioning cylinder, three annularly distributed outer protective shells rotatably mounted on the bottom end of the positioning cylinder, each outer protective shell having a retractable inner protective shell inserted inside, and movable webs for increasing the bearing area at the distal ends of both the inner and outer protective shells, a mating sleeve provided on the lower side of the positioning cylinder, the mating sleeve being located inside the area enclosed by the three outer protective shells, a positioning tag being inserted inside the positioning cylinder, and after determining the pile position, the positioning tag being inserted into the positioning cylinder and the mating sleeve and then into the foundation, serving as the reference center point for subsequent embedded part installation, an auxiliary embedding device being provided inside the outer protective shell to improve the soil penetration efficiency of the positioning tag by transmitting insertion force, a rectangular hole being opened on the outer surface of the outer protective shell, a balancing sleeve being provided inside the rectangular hole, a horizontal auxiliary device being integrated between the balancing sleeve and the outer protective shell to indicate the real-time horizontal status of the positioning cylinder on the foundation, and a central tube being inserted inside the outer protective shell.

[0005] As a further embodiment of the present invention, multiple connecting arms are rotatably mounted on the outer surface of the fitting sleeve, and multiple clamping plates are rotatably mounted on the inner end of the fitting sleeve. The clamping plates are arranged in a ring. By rotatably mounting multiple connecting arms on the outer surface of the fitting sleeve and setting multiple clamping plates arranged in a ring at the inner end of the fitting sleeve, the connecting arms can drive the clamping plates to open or close synchronously, so that the clamping plates form a ring-shaped limit and uniform clamping support for the foundation, thereby achieving stable positioning even in soft soil or gravel terrain, improving the overall stability and anti-displacement ability of the positioning cylinder in mountainous environments, and avoiding tilting or displacement caused by uneven local forces.

[0006] As a further embodiment of the present invention, a transition rod is inserted inside the central tube, a locking sleeve is fixedly installed at the upper end of the inner protective shell, a passive ring is rotatably installed at the end of the locking sleeve away from the central tube, a central rod is fixedly connected to the bottom end of the transition rod, and the passive ring is sleeved on the surface of the central rod. By inserting the transition rod inside the central tube, setting the locking sleeve at the upper end of the inner protective shell, and rotatably installing the passive ring at the end of the locking sleeve away from the central tube, the passive ring is sleeved on the surface of the central rod. When the central rod is subjected to an insertion force or a return force and undergoes axial displacement, the passive ring can perform a limiting fit with the central rod at the locking sleeve, thereby realizing synchronous guidance and locking displacement control between the central tube and the inner protective shell.

[0007] As a further embodiment of the present invention, the auxiliary embedding device includes a response sleeve, the side of the connecting arm away from the mating sleeve is rotatably connected to the response sleeve, a buffer cylinder is fixedly installed at the upper end of the response sleeve, and a support frame is detachably installed on the outer surface of the buffer cylinder, and a passive gear is rotatably installed at the inner end of the support frame.

[0008] As a further embodiment of the present invention, the passive gears are divided into two groups, and multiple water droplet blocks are rotatably mounted at one end of the two groups of passive gears that are close to each other. The water droplet blocks are arranged in a ring. A rack is fixedly mounted on the outer surface of the central tube. The rack meshes with the water droplet blocks arranged in a ring. The passive gears are engaged with the support frame by a return torsion spring. By dividing the passive gears into two groups and rotatably mounting the water droplet blocks arranged in a ring at one end of the two groups of passive gears that are close to each other, the water droplet blocks and the rack on the outside of the central tube form a meshing transmission relationship. When the central tube undergoes vertical displacement or insertion torque transmission, the water droplet blocks can be driven to achieve synchronous meshing motion along the ring direction.

[0009] As a further embodiment of the present invention, a transmission gear is rotatably mounted on the inner end of the support frame, the transmission gear meshes with the driven gear, an auxiliary wheel is rotatably mounted inside the support frame, a drive wheel is fixedly mounted on the surface of the transmission gear, the drive wheel and the auxiliary wheel are tensioned and sleeved together by a transmission belt, and an assisting hammer is fixedly mounted on the outer surface of the auxiliary wheel, the assisting hammer uses rotational inertia to accumulate and provide the required kinetic potential energy.

[0010] As a further embodiment of the present invention, the horizontal auxiliary device includes a connecting block, which is fixedly installed on the upper end of the outer shell. A dial ring is rotatably installed on the upper end of the connecting block and is fixedly connected to the central tube. A rotating frame is rotatably installed on the inner end of the outer shell, and the free end of the rotating frame is rotatably connected to the balance sleeve. By setting a connecting block on the upper end of the outer shell and rotatably installing a dial ring fixedly connected to the central tube on the connecting block, and simultaneously setting a rotating frame rotatably connected to the balance sleeve on the inner end of the outer shell, the horizontal auxiliary device can synchronously adjust the attitude of the central tube when the attitude of the outer shell changes relative to the foundation.

[0011] As a further embodiment of the present invention, a passive frame is provided inside the connecting block, and a movable column is slidably installed at the upper end of the passive frame. The movable column is connected to the connecting block by a return spring. A notch is provided on the outer surface of the dial ring. When the dial ring rotates, the notch on the surface rotates to the movable column, and the movable column is embedded therein to achieve positioning. A synchronization tube is fixedly connected to the outer surface of the passive frame, and the synchronization tube is provided inside the movable column.

[0012] As a further embodiment of the present invention, a float is fixedly installed inside the balance sleeve, a sealing cover is detachably installed at the upper end of the float, and the sealing cover is fixedly connected to the synchronization tube. A passive plug is inserted inside the sealing cover, a protrusion is fixedly installed at the bottom end of the passive plug, a stabilizing ring is fixedly installed at the inner end of the float, a push rod is inserted inside the stabilizing ring, the upper end of the push rod contacts the protrusion at the bottom end of the passive plug, and a float ring is fixedly connected to the end of the push rod away from the stabilizing ring.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. When using this invention, the energy transfer structure formed between the sleeve and the response sleeve, along with the reset torsion spring and the assist hammer, can provide additional driving force when inserting the positioning tag. The depth of the benchmark pile can be completed without the need for traditional external force hammering, allowing construction personnel to complete the positioning and placement of embedded parts under single-person operation, improving the efficiency of the initial benchmark construction of the pile foundation, and improving the overall accuracy and reliability of the pile foundation installation. It is especially suitable for pile foundation positioning construction scenarios in mountain photovoltaic projects. 2. When using this invention, by setting up a multi-segment telescopic support structure of outer and inner shells, and adding movable flippers at the bottom, a larger support contact area can be formed on mountainous or soft foundations, effectively preventing the device from sinking or tilting during use, thereby improving the stability and pressure bearing capacity of the positioning device under complex foundation conditions; at the same time, the locking mechanism of the inner shell can achieve rapid limiting at a predetermined height position, so that the support structure remains stable after extension and will not produce secondary displacement. 3. The automatic leveling mechanism integrated within this invention can achieve adaptive posture correction on inclined foundations, ensuring that the positioning cylinder is always in a horizontal state, which helps to guarantee the vertical accuracy of the pile position benchmark during the construction of embedded parts.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1: Please refer to Figures 1-5 A positioning device for pre-embedded pile foundations in a mountain photovoltaic project includes a positioning cylinder 1. Three outer protective shells 3 arranged in a ring are rotatably installed at the bottom end of the positioning cylinder 1. Each outer protective shell 3 has a retractable inner protective shell 201 inserted inside. The inner protective shell 201 can be pulled out from the outer protective shell 3 to adapt to different terrains and extend the overall support length of the positioning device. The far ends of the inner protective shell 201 and the outer protective shell 3 are provided with movable webs to increase the bearing area, forming a larger support contact surface on soft foundations or uneven ground, thereby preventing the inner protective shell 201 from sinking or swaying after it is fully extended, and ensuring the stability and verticality of the pile foundation positioning benchmark. A fitting sleeve 101 is provided on the lower side of the positioning cylinder 1. The fitting sleeve 101 is located inside the position enclosed by the three outer shells 3. A positioning tag 2 is inserted inside the positioning cylinder 1. After the pile position is determined, the positioning tag 2 is inserted into the positioning cylinder 1 and the fitting sleeve 101 and then inserted into the foundation so that it serves as the reference center point for the subsequent installation of embedded parts, thereby improving the accuracy of the pile foundation installation. To achieve labor-saving construction during pile positioning and insertion, an auxiliary embedding device is installed inside the outer shell 3. This device improves the soil penetration efficiency of the positioning tag 2 by transmitting the insertion force, and the positioning benchmark can be established without the need for external force to strike, making the construction process more stable and controllable. A rectangular hole is opened on the outer surface of the outer shell 3, and a balance sleeve 4 is installed inside the rectangular hole. A horizontal auxiliary device is integrated between the balance sleeve 4 and the outer shell 3 to indicate the real-time horizontal status of the positioning cylinder 1 on the foundation, so as to ensure that the installation direction of the pile foundation embedded parts meets the design requirements. A central tube 202 is inserted inside the outer shell 3.

[0018] like Figures 4-7 Multiple connecting arms 102 are rotatably mounted on the outer surface of the fitting sleeve 101. The connecting arms 102 are formed by two folding arms rotatably connected to each other. Multiple clamping plates 103 are rotatably mounted on the inner end of the fitting sleeve 101. The clamping plates 103 are arranged in a ring. After the positioning tag 2 is inserted into the fitting sleeve 101, its surface contacts the clamping plate 103, which can only be flipped down. The elastic force of the spring makes the clamping plate 103 always press the positioning tag 2. When the positioning tag 2 is lifted, the force is transmitted to the clamping plate 103. Since the clamping plate 103 cannot be flipped up, it forms a self-locking mechanism, thereby clamping the positioning tag 2 and driving the fitting sleeve 101 to move upward as a whole. A connecting rod 203 is inserted inside the central tube 202. A rectangular block is fixedly installed on the outer surface of the connecting rod 203. A rectangular groove is opened inside the central tube 202, and the rectangular block passes through the rectangular groove. When the central rod 205 rotates, it will directly drive the connecting rod 203 to rotate. A locking sleeve 206 is fixedly installed at the upper end of the inner shell 201. A passive ring 208 is rotatably installed at the end of the locking sleeve 206 away from the central tube 202. The bottom end of the connecting rod 203 is fixedly connected to the central rod 205, and the passive ring 208 is sleeved on the surface of the central rod 205. A rectangular sliding groove is opened on the surface of the central rod 205. A rectangular block is fixedly installed on the inner surface of the passive ring 208, and the rectangular block passes through the rectangular sliding groove. When the central rod 205 rotates, it will drive the passive ring 208 to rotate, while not affecting the up and down movement of the passive ring 208. Multiple locking blocks 207 are slidably installed on one end of the locking sleeve 206 near the passive ring 208. Multiple top blocks 209 are fixedly installed inside the passive ring 208. The top blocks 209 are arc-shaped and contact the outer surface of the locking blocks 207. Specifically, when the rubber anti-slip sleeve of the locking block 207 presses against the center rod 205, the contact pressure is converted into huge friction force, thereby achieving reliable locking. Thus, the three inner shells 201 can achieve high locking on both flat and sloping foundations.

[0019] Example 2: Please refer to Figure 4 , Figure 5 , Figure 8 A positioning device for pre-embedded piles in a mountain photovoltaic project, based on embodiment 1, includes an auxiliary embedding device comprising a response sleeve 401, and a connecting arm 102 rotatably connected to the response sleeve 401 on the side away from the mating sleeve 101. Therefore, during the upward movement of the mating sleeve 101, the response sleeve 401 will be moved upward through the connecting arm 102. A buffer cylinder 402 is fixedly installed on the upper end of the response sleeve 401, and a support frame 403 is detachably installed on the outer surface of the buffer cylinder 402. A passive gear 404 is rotatably installed on the inner end of the support frame 403. The driven gears 404 are divided into two groups. Multiple water droplet blocks 406 are rotatably mounted on one end of the two groups of driven gears 404 that are close to each other. The water droplet blocks 406 are arranged in a ring. Multiple limiting blocks are provided between the two groups of driven gears 404. The limiting blocks limit the water droplet blocks 406, so that they can only rotate within a limited angle range. A rack 204 is fixedly mounted on the outer surface of the central tube 202. The rack 204 meshes with the ring-arranged water droplet blocks 406. Specifically, by rotating the central tube 202, the rack 204 can rotate accordingly and disengage from the water droplet blocks 406. To avoid interference, the rack 204 is designed not to mesh with the driven gears 404, and the rack 204 is narrower than the width of the water droplet blocks 406 to ensure smooth rotation.

[0020] The passive gear 404 is engaged with the support frame 403 by a reset torsion spring 405. When the buffer cylinder 402 moves upward, the water droplet block 406 is restricted by the limit block and cannot rotate. After contacting the rack 204, it transmits linear motion to the passive gear 404, forcing it to rotate. When the passive gear 404 rotates, it stores force in the reset torsion spring 405. During the release phase of the reset torsion spring 405, the water droplet block 406 moves in the opposite direction. At this time, its swing direction is out of the range of action of the limit block, so it is not restricted by the limit block, thus enabling the passive gear 404 to reset and rotate normally. A transmission gear 407 is rotatably mounted on the inner end of the support frame 403. The transmission gear 407 meshes with the driven gear 404. An auxiliary wheel 409 is rotatably mounted inside the support frame 403. A drive wheel is fixedly mounted on the surface of the transmission gear 407. The drive wheel and the auxiliary wheel 409 are tensioned and sleeved together by a transmission belt 408. Specifically, a tensioner is provided inside the support frame 403, which can automatically maintain the tension of the transmission belt 408 to ensure that the force of the drive wheel is efficiently transmitted to the auxiliary wheel 409. A booster hammer 410 is fixedly installed on the outer surface of the auxiliary wheel 409. The booster hammer 410 uses rotational inertia to accumulate and provide the required kinetic potential energy. The buffer cylinder 402 falls as the booster hammer 410 rotates. The clamping plate 103 locks the positioning pin 2, directly converting this downward potential energy into a driving force for the positioning pin 2. The downward pressure of the worker on the positioning pin 2 and the auxiliary power of the booster hammer 410 work together to allow the positioning pin 2 to be driven deeper into the foundation. At the same time, the support frame 403 can be flexibly removed from the buffer cylinder 402, so that booster hammers of different weights can be replaced according to different terrains.

[0021] Please see Figure 5 , Figures 9-12 The horizontal auxiliary device includes a connecting block 301, which is fixedly installed on the upper end of the outer shell 3. A dial ring 302 is rotatably installed on the upper end of the connecting block 301 and is fixedly connected to the central tube 202. A rotating frame 306 is rotatably installed on the inner end of the outer shell 3, and the free end of the rotating frame 306 is rotatably connected to the balance sleeve 4. Specifically, the rotating frame 306 achieves angle self-locking through a built-in damping shaft, while the balance sleeve 4 connected to it maintains free rotation. A passive frame 304 is inserted inside the connecting block 301. A movable column 303 is slidably installed on the upper end of the passive frame 304. The movable column 303 is connected to the connecting block 301 by a return spring 307. A notch is opened on the outer surface of the dial ring 302. When the dial ring 302 rotates, the notch on the surface rotates to the movable column 303, and the movable column 303 is embedded in it to achieve positioning. A synchronization tube 305 is fixedly connected to the outer surface of the passive frame 304. The synchronization tube 305 is inserted inside the movable column 303.

[0022] A float 310 is fixedly installed inside the balance sleeve 4. The float 310 is filled with liquid. A sealing cover 308 is detachably installed on the upper end of the float 310 and is fixedly connected to the synchronization pipe 305. A passive plug 311 is inserted inside the sealing cover 308. A protrusion is fixedly installed at the bottom end of the passive plug 311. A stabilizing ring 309 is fixedly installed inside the float 310. A push rod 312 is inserted inside the stabilizing ring 309. The stabilizing ring 309 only limits the movement area of ​​the push rod 312. The push rod 312 can deflect at any angle. The upper end of the push rod 312 contacts the protrusion at the bottom end of the passive plug 311. A float ring 313 is fixedly connected to the end of the push rod 312 away from the stabilizing ring 309. Specifically, the density of the float ring 313 is less than that of the liquid inside the float 310, and the liquid inside the float 310 only submerges the float ring 313 to half its height. The bottom of the sealing cap 308 is bowl-shaped. Therefore, the push rod 312 always maintains an upward force under the buoyancy of the float ring 313. Only when the float 310 is in a vertical state will the push rod 312 push the passive plug 311 upward. It is worth noting that the sealing cover 308 is equipped with a limiting block to prevent the protrusion at the bottom of the passive plug 311 from retracting completely into its interior, and the diameter of the push rod 312 is larger than that of the protrusion at the bottom of the passive plug 311. The buoyancy force generated by the liquid inside the float 310 on the float ring 313 is greater than the total mass of the movable column 303 and the passive frame 304.

[0023] The working principle of this invention is: In use, the outer shell 3 is unfolded. The unfolding angle of the outer shell 3 is limited to ensure that the response sleeve 401 can descend smoothly and its function is not affected. The inner shell 201 is then pulled out. If the foundation is flat, after pulling out the inner shell 201, the dial ring 302 is rotated directly. The dial ring 302 drives the adapter rod 203 to rotate through the central tube 202. Then, the adapter rod 203 drives the passive ring 208 to rotate through the central rod 205. When the passive ring 208 rotates, the outer surface of the top block 209 will press and push the locking block 207, causing the locking block 207 to move towards the central rod 205 and finally contact the outer surface of the central rod 205, thus locking the central rod 205 and preventing the inner shell 201 from moving further. If on a sloping foundation, after fixing two of the inner shells 201 in position, pull out the balance sleeve 4 on the side where the inner shell 201 is not fixed. At this time, the passive frame 304 will move downward under the action of gravity. Then, try to slowly rotate the outer shell 3 located on the locked side of the inner shell 201. When tentatively rotating the outer shell 3, the float ring 313 in the float 310 always remains horizontal. Push the upper end of the push rod 312 to gradually approach the protrusion at the bottom of the passive plug 311 until it contacts the protrusion and pushes the protrusion upward. Then the passive plug 311 moves upward and is transmitted to the inside of the moving column 303 through the synchronization tube 305, so that the moving column 303 moves upward. At this time, the staff observes the movement of the moving column 303 and starts to rotate the last dial ring 302 to lock the height of the last inner shell 201. During the rotation of the central tube 202, the rack 204 meshes with the teardrop block 406. At this point, the device has completed automatic leveling on the inclined foundation and stabilized in a horizontal state. Then, the positioning tag 2 is inserted into the positioning cylinder 1 and passes through the interior of the mating sleeve 101. As the positioning tag 2 goes deeper into the foundation, if it is to go deeper, the positioning tag 2 is pulled out. The mating sleeve 101 then moves with the positioning tag 2 under the action of the clamping plate 103. As the mating sleeve 101 moves upward, it drives the response sleeve 401 to move through the connecting arm 102. At this time, the water droplet block 406 and the rack 204 mesh with each other, driving the passive gear 404 to rotate. When the passive gear 404 rotates, it will store the reset torsion spring 405. Then, the positioning pin 2 is pressed down again. At this time, the reset torsion spring 405 is no longer under force and begins to release its elastic force, which drives the driven gear 404 to rotate. At this time, the transmission gear 407 meshes with the driven gear 404 and rotates, driving the auxiliary wheel 409 to rotate through the transmission belt 408. The buffer cylinder 402 falls down as the assist hammer 410 rotates. Using the self-locking of the positioning pin 2 by the clamping plate 103, this downward potential energy is directly converted into the driving force for the positioning pin 2. The downward pressure of the worker on the positioning pin 2 and the auxiliary power of the assist hammer 410 work together to make the positioning pin 2 implanted deeper into the foundation. This process is repeated until the positioning pin 2 is implanted to a satisfactory depth.

[0024] When the work is completed, turn the dial 302 to stop locking the height of the inner protective shell 201, and retract the balance sleeve 4 into the outer protective shell 3. Then push the inner protective shell 201 back into the outer protective shell 3 to complete the storage.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
