Description

Technical Field

[0001] This invention relates to the field of geotechnical engineering technology, specifically to a hoisting mechanism for geotechnical engineering pile foundation construction. Background Technology

[0002] Geotechnical engineering pile foundation is a support system consisting of columnar members with the pile body embedded in the ground and a reinforced concrete platform connecting the pile top to the superstructure. The hoisting mechanism for pile foundation construction in geotechnical engineering is a key piece of equipment used for hoisting, positioning, and pile driving operations during pile foundation construction. It typically consists of a main beam, boom, lifting system, slewing mechanism, traveling device, and control system. Through mechanical or hydraulic drive, it enables the vertical hoisting, precise positioning, and lowering of components such as precast piles or reinforcing cages. This adapts to the construction needs of various pile types, including bored piles and precast piles, with different pile diameters, lengths, and geological conditions. It ensures the stability, verticality, and positioning accuracy of the pile body during hoisting, thereby improving the efficiency and quality of pile foundation construction. It is widely used in pile foundation construction for bridges, buildings, ports, and other projects.

[0003] However, when using existing geotechnical engineering pile foundation construction hoisting mechanisms to lift precast piles and insert them into corresponding installation holes, the relative position of the precast pile and the installation hole is usually observed manually, which has poor accuracy. During the lowering operation, the position of the precast pile may need to be adjusted frequently. Furthermore, when lifting precast piles that are cylindrical without pre-embedded connecting components, it is necessary to first tie steel wire ropes to the outer surface of the precast pile and then install connecting components on the steel wire ropes. This lifting process is quite cumbersome and will affect the installation efficiency of geotechnical engineering pile foundations to a certain extent. Therefore, it does not meet the existing requirements. To address this, we propose a geotechnical engineering pile foundation construction hoisting mechanism. Summary of the Invention

[0004] The purpose of this invention is to provide a hoisting mechanism for geotechnical engineering pile foundation construction, in order to solve the problems mentioned in the background art. When using existing hoisting mechanisms for geotechnical engineering pile foundation construction to lift precast piles and insert them into the corresponding installation holes, the relative position of the precast pile and the installation hole is usually observed manually, which has poor accuracy. During the lowering operation, the position of the precast pile may need to be adjusted for a long time. In addition, when lifting precast piles that are cylindrical without pre-embedded connecting components, it is necessary to first tie the wire rope to the outer surface of the precast pile and then install the connecting components on the wire rope.

[0008] Preferably, the synchronous drive mechanism includes an expansion motor, the output shaft of which is connected to a threaded rod via a coupling. An internal threaded sleeve is installed on the upper side of the outer surface of the threaded rod via a threaded structure. A push sleeve, which is slidably installed inside the annular shell, is fixedly connected to the front of the internal threaded sleeve.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes a pile foundation winding and fixing mechanism for suspending precast piles, with an inner side equipped with a pile foundation winding and fixing wire rope integrally composed of multiple strands of steel wire. When it is necessary to use equipment to lift a precast pile with no pre-embedded connecting components on its outer surface and an overall cylindrical shape, the pile foundation winding and fixing mechanism is directly placed on the upper side of the outer surface of the precast pile. Then, the winding and fixing motor is started to inwardly retract the pile foundation winding and fixing wire rope, making it tightly wound around the outer surface of the precast pile, thereby fixing the precast pile to the inner side of the pile foundation winding and fixing mechanism. Through the above technical solution, there is no need to rely on pre-embedded connecting components on the surface of the precast pile, and the cylindrical precast pile body can be directly and quickly fixed, thereby improving the efficiency when installing such precast piles. 2. This invention, by moving the precast pile to be lifted above the corresponding installation hole, uses an infrared ring positioning installation mechanism to directly emit multiple infrared rays arranged in a ring from top to bottom. Only the infrared rays that are not in contact with the precast pile will directly illuminate the area around the installation hole, thus directly displaying the relative position of the installation hole and the precast pile. Through this technical solution, operators can directly observe the distribution of unobstructed infrared rays and judge the concentricity and offset of the precast pile and the installation hole in real time. This upgrades traditional experience-based visual inspection to data-driven visual guidance, thereby improving positioning efficiency and accelerating work efficiency. It also eliminates the need for repeated lifting and adjustment or the use of external measuring instruments, achieving one-time lifting and rapid positioning, shortening the time the pile is suspended in the air, and accelerating the pile driving construction rhythm. Infrared positioning is not limited by natural lighting conditions and can still maintain clear projection indication during nighttime construction, expanding the time window for pile foundation construction. Furthermore, by predicting the pile dropping position in advance, it can avoid the risk of collision between the pile and the hole wall, reducing the possibility of pile damage or hole wall collapse accidents caused by misalignment.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Please see Figures 1 to 6 An embodiment of the present invention provides a hoisting mechanism for geotechnical engineering pile foundation construction, including a main body 1 of the engineering pile foundation hoisting machine. A pile foundation winding and fixing mechanism is provided on one side of the main body 1. The pile foundation winding and fixing mechanism includes a shrinking mechanism and a cross-shaped outer shell 16. A sliding groove 8 is provided at each of the four corners of the lower end face of the cross-shaped outer shell 16. An electric slider 9 is installed on one side inside the sliding groove 8. A strip bracket 10 is fixed on the lower end face of the electric slider 9. A steel wire rope 7 for pile foundation winding and fixing is provided between the four strip brackets 10. A C-shaped steel wire rope fixing head 15 is connected to the side of the strip bracket 10 facing the steel wire rope 7 for pile foundation winding and fixing, which is movably sleeved on the outer surface of the steel wire rope 7 for pile foundation winding and fixing. The steel wire rope 7 for pile foundation winding and fixing is spring-shaped as a whole. The shrinking mechanism can gradually shrink the steel wire rope 7 for pile foundation winding and fixing inward. An infrared ring positioning and installation mechanism 2 is provided above the pile foundation winding and fixing mechanism. The infrared ring positioning and installation mechanism 2 includes an annular shell 202 and a synchronous drive mechanism. A ring of strip sliders 210 is slidably installed on the lower end face of the annular shell 202. Multiple infrared beam heads 211 are installed on the lower end face of the strip sliders 210, and the synchronous drive mechanism can move the four strip sliders 210 outward or inward synchronously. A boom 19 is fixedly installed on one side of the outer surface of the main body 1 of the engineering pile foundation hoisting machine. Multiple steel wire ropes are provided on the inner side of the boom 19. The front end of the wire rope is connected to a boom roller 20 installed inside the annular outer shell 202. The lower end of the boom roller 20 is connected to multiple suspension wire ropes 21, and the lower end of the multiple suspension wire ropes 21 is connected to a hook head 3 fixed to the upper end of the pile foundation winding and fixing mechanism. A control room 22 is fixedly installed on the other side of the outer surface of the main body 1 of the engineering pile foundation hoisting machine, and the infrared ring positioning installation mechanism 2 and the pile foundation winding and fixing mechanism are both electrically connected to the control room 22. The operation of the entire equipment can be controlled through the boom roller 20. When the equipment is needed, lift the wire rope head 18 and directly place the pile foundation winding and fixing mechanism, which is indirectly connected to the wire rope head 18, onto the outer surface of the top end of the precast pile. Then, the electric slider 9 drives the strip bracket 10 to approach the precast pile. During the movement of the strip bracket 10, the pile foundation winding and fixing wire rope 7, which is connected to it through the C-shaped wire rope fixing clip 15, will move together. When the pile foundation winding and fixing wire rope 7 is slightly touching the precast pile, turn off the electric slider 9.

[0020] The shrinkage mechanism includes a winding and fixing motor 4. The output shaft of the winding and fixing motor 4 is connected to a transmission shaft 5 via a coupling. A wire rope take-up roller 6 is fixedly sleeved on the outer surface of the transmission shaft 5. A wire rope head 18 is fixed on one side of the outer surface of the wire rope take-up roller 6, and the wire rope head 18 and the pile foundation winding and fixing wire rope 7 are integrally formed. When the electric slider 9 is closed, the winding and fixing motor 4 is started to drive the transmission shaft 5 connected to it to rotate. When the transmission shaft 5 rotates, the wire rope take-up roller 6 fixedly sleeved on the outer surface of the transmission shaft 5 will rotate together. At this time, the wire rope take-up roller 6 is rotated clockwise. When the wire rope take-up roller 6 rotates clockwise, it will continuously pull the pile foundation winding and fixing wire rope 7 to shrink through the wire rope head 18 fixed on its outer surface, so that the spring-shaped pile foundation winding and fixing wire rope 7 tightly wraps the outer surface of the precast pile, thereby achieving stable winding and fixing of the precast pile. The above technical solution eliminates the need for pre-embedded connecting components on the surface of the precast pile, allowing for direct and rapid fixing of the cylindrical precast pile body, thereby improving the efficiency of installing this type of precast pile.

[0021] The synchronous drive mechanism includes an expansion motor 203. The output shaft of the expansion motor 203 is connected to a threaded rod 204 via a coupling. An internal threaded sleeve 205 is installed on the upper side of the outer surface of the threaded rod 204 via a threaded structure. A pusher sleeve 206, which is slidably installed inside an annular housing 202, is fixedly connected to the front of the internal threaded sleeve 205. The lower end face of the pusher sleeve 206 is an inclined surface 207. A rectangular pusher block 208 is provided below the inclined surface 207. A spring 2 is connected to one side of the outer surface of the rectangular pusher block 208. 09, and multiple rectangular push blocks 208 are respectively fixed to the upper end face of multiple strip sliders 210; the infrared ring positioning installation mechanism 2 also includes a large electric rotating shaft 201, the upper end face of the annular shell 202 is fixed to the large electric rotating shaft 201, and an electric level balancer 212 is fixedly installed on the lower side inside the large electric rotating shaft 201; the horizontal angle of the annular shell 202 fixed to the lower end face of the large electric rotating shaft 201 can be detected in real time through the annular shell 202 installed inside the large electric rotating shaft 201. When the precast pile is lifted, it is moved above the corresponding installation hole by the main body 1 of the engineering pile foundation hoisting machine. Then, the large electric rotating shaft 201 is started to adjust the horizontal angle of the annular shell 202 fixed to its lower end face so that it is completely parallel to the ground. After the overall horizontal angle of the annular outer shell 202 is adjusted, all infrared ray heads 211 are activated to irradiate multiple circles of infrared light downwards. Once the infrared ray heads 211 are activated, the expansion motor 203 is started to drive the connected threaded rod 204 to rotate. When the threaded rod 204 rotates, the inner threaded sleeve 205, installed on the outer surface of the threaded rod 204 via a threaded structure, will move up and down under the drive of the threaded structure. As the inner threaded sleeve 205 moves downwards, the push sleeve 206, which is fixed to it, will also descend. As the push sleeve 206 descends, the lower end of the push sleeve 206... The inclined surface 207 will contact the rectangular push block 208 and gradually push the rectangular push block 208 outward. When the rectangular push block 208 is pushed outward, the strip slider 210 fixed to it will also be pushed outward. As the strip slider 210 moves, the multiple infrared rings generated by the multiple infrared ray heads 211 installed on the lower end face of the strip slider 210 will gradually expand as it moves outward. If an infrared ray head 211 moves away from the top of the precast pile, the infrared rays generated by the infrared ray head 211 will directly pass over the precast pile and irradiate the area around the installation hole. With the above technical solution, operators can directly observe the distribution of unobstructed infrared light, and judge the concentricity and offset of the precast pile and the installation hole in real time. This upgrades the traditional experience-based visual inspection to data-driven visual guidance, thereby improving positioning efficiency and speeding up the operation. At the same time, there is no need for repeated lifting and adjustment or the use of external measuring instruments. It can achieve one-time hoisting and rapid positioning, shorten the time the pile is suspended in the air, and speed up the pile driving construction rhythm. In addition, infrared positioning is not limited by natural light conditions and can still maintain clear projection indication during night construction, which expands the time window for pile foundation construction. Furthermore, by predicting the pile dropping position in advance, the risk of collision between the pile and the hole wall can be avoided, reducing the possibility of pile damage or hole wall collapse accidents caused by deviation. By using a single expansion motor 203 to synchronously drive all the strip sliders 210 outward, it is possible to ensure that the infrared beam heads 211 in a circle maintain the same relative position, thereby improving the irradiation accuracy of multiple circles of infrared rays. When spring 209 is pushed outward, it will compress the corresponding spring 209. When the precast pile and the installation hole are aligned, the precast pile is inserted into the installation hole by the main body 1 of the engineering pile foundation hoisting machine. Then, the expansion motor 203 moves the pushing sleeve 206 upward. When the pushing sleeve 206 moves upward, the reaction force of the compressed spring 209 can gradually push the strip slider 210 back to its original position. When all the strip sliders 210 have returned to their original positions, the operation of the infrared ring positioning installation mechanism 2 is paused before the next operation.

[0022] The strip bracket 10 has a spring groove 11 corresponding to the C-shaped wire rope fixing clip 15 inside. A metal ring 12 is located inside the spring groove 11, and a connecting rod 14 is connected to the axis of the metal ring 12. A return spring 13 is fitted onto the outer surface of the connecting rod 14. The two ends of the return spring 13 are connected to the inner walls of the metal ring 12 and the spring groove 11, respectively. The face of the connecting rod 14 facing the C-shaped wire rope fixing clip 15 is fixed to the C-shaped wire rope fixing clip 15. The inner wall of the C-shaped wire rope fixing clip 15 is coated with lubricating oil, and the pile foundation is wrapped with steel wire for fixing. The rope 7 is made of multiple steel wires; the C-shaped steel wire rope fixing clip 15 is C-shaped and is made of high-hardness alloy steel in one piece; when the steel wire rope 7 for pile foundation winding and fixing is pulled inward to contract and fit more tightly with the precast pile, the C-shaped steel wire rope fixing clip 15, which is movably sleeved on its outer surface, will be pulled slightly inward. When the C-shaped steel wire rope fixing clip 15 moves, the metal ring 12 connected to it through the connecting rod 14 will be pulled inward together and squeeze the return spring 13 directly connected to the metal ring 12. After the precast pile enters the installation hole, the wire rope winding roller 6 is rotated in the opposite direction by the winding and fixing motor 4. When the wire rope winding roller 6 rotates in the opposite direction, the reaction force of the compressed return spring 13 can push the excessively contracted pile foundation winding and fixing wire rope 7 outward, thereby releasing the winding and fixing between the pile foundation winding and fixing wire rope 7 and the precast pile.

[0023] A first control module 213 is fixedly installed on one side of the outer surface of the expansion motor 203, and a second control module 17 is fixedly installed on one side of the outer surface of the winding and fixing motor 4. The second control module 17 and the first control module 213 are respectively connected to the winding and fixing motor 4 and the expansion motor 203 by electrical signals. Through the first control module 213 and the second control module 17, the control room 22 can remotely control the operation of the expansion motor 203 and the winding and fixing motor 4.

[0024] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
