Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to a lifting device for a manually bored pile with a variable diameter. Background Art

[0002] In renewable energy power generation projects, various power generation units must aggregate their own power and transmit it to substations, or, alternatively, substations must aggregate power and transmit it to the power grid. In this process, towers, as critical infrastructure, are rapidly increasing in number as demand grows. Whether constructing tower foundations for 35kV, 110kV, or even higher voltage levels, manual bored pile construction is considered a critical project due to its complexity and risk, placing extremely high demands on construction safety.

[0003] During the construction of bored piles for tower foundations, efficiently and safely transporting waste materials, such as excess soil and rock, from the piles is crucial for ensuring the stability of the hole and the safety of workers inside. Given the diversity of bored piles due to varying hole diameters and retaining wall requirements, a device is needed that can flexibly adapt to various hole diameters while ensuring the smooth and rapid transfer of waste within the hole. Utility Model Content

[0004] The utility model aims to provide a variable-diameter artificial bored pile lifting device to realize the transfer of waste in artificial bored piles with different hole diameters.

[0005] A variable-diameter bored pile lifting device in this scheme includes a support frame, four connecting plates and a lifting assembly for transferring waste out of the bored pile. The support frame includes a base and a mounting seat, both of which have parallelogram cross-sections. The mounting seat is located directly above the base and the centers of the two are on the same vertical line. The base is composed of four retractable bottom plates. The mounting seat and the four corners of the base correspond to each other and are connected by connecting plates. The connection between the connecting plate, the mounting seat and the base is a movable connection; the lifting assembly is installed on the top of the mounting seat.

[0006] The working principle and beneficial effects of this solution are as follows: During use, the base's four retractable base plates are adjusted to adjust the length and width according to the bored pile diameter, thereby accommodating bored piles of varying diameters. The flexible connection between the connecting plate, mounting bracket, and base allows for angle adjustment to accommodate changes in base length and width, ensuring the stability and integrity of the device. The lifting assembly then lifts the waste out of the bored pile, completing the waste transfer process.

[0007] This solution utilizes a retractable base design that allows for easy adjustment of the base size to accommodate bored piles of varying bore diameters. This significantly improves the versatility and applicability of the device, avoids the need for multiple lifting devices of varying specifications due to differences in bore diameter, and reduces equipment costs and the complexity of construction preparation. Furthermore, the rational layout of the base and mounting bracket, as well as the connection method of the connecting plate, provide reliable support and protection for the transfer of waste within the bored piles. During the transfer process, it effectively prevents accidents such as waste falling due to device instability, safeguarding the lives of workers within the bored piles. It also helps maintain the stability of the bored pile mouth and reduces potential safety hazards.

[0008] Furthermore, the mounting base is composed of four support plates fixedly connected end to end. The lifting assembly includes two fixed plates and bearings mounted on the fixed plates. The two fixed plates are respectively fixedly connected to two opposing support plates. The two bearings are connected to the same rotating shaft, one end of which is connected to a rocker or motor. A reel is mounted on the rotating shaft, and a wire rope is provided on the reel. The end of the wire rope away from the reel is fixedly connected to a hook. The rotating shaft is driven by a rocker or motor to rotate, which drives the reel to retract and release the wire rope, achieving efficient lifting and lowering of waste. Manual rocker operation or motor drive can be selected according to actual conditions, making waste transfer convenient in different construction scenarios.

[0009] Furthermore, the connecting plate is tilted. When the base diameter is adjusted, the tilted connecting plate can better adapt to the angle change, effectively transmitting and distributing the force, and making the connection between the base and the mounting bracket more stable. In actual construction, the environment inside the bored pile is relatively complex and may be affected by various lateral forces. The tilted connecting plate can better resist these forces, ensuring the stability of the device during waste transportation, reducing the risk of device shaking or tilting due to external interference, and further ensuring construction safety.

[0010] Furthermore, the movable connection between the connecting plate, the base plate, and the support plate is a pin connection. This allows the connecting plate to rotate freely within a certain range, effectively accommodating angular changes caused by base diameter adjustment, making assembly and adjustment of the device more convenient and quicker. Furthermore, the pin connection offers high load-bearing capacity and shear strength, ensuring a secure and reliable connection between the connecting plate, the base, and the mounting bracket during waste transfer, preventing loosening or falling due to stress, effectively improving the overall safety and service life of the device.

[0011] Furthermore, the base plate includes two adjustment plates that are detachably connected to each other. Both adjustment plates are provided with threaded holes, and some of the threaded holes are threadedly connected with fasteners, which are bolts or screws. The two adjustment plates are fixed by connecting the fasteners to the threaded holes. At the construction site, the actual size of the bored piles can be manually excavated, and the adjustment plates can be quickly disassembled and assembled, and fixed by fasteners (bolts or screws). The detachable connection of the adjustment plates by fasteners is not only convenient for transportation and storage, but also can be flexibly switched between bored piles of different apertures, thereby improving the efficiency and economy of the device. At the same time, the threaded connection method has good self-locking properties, which can ensure that the connection of the base plate will not loosen due to vibration or other external forces during the operation of the device, thereby ensuring the stability and reliability of the device.

[0012] Furthermore, the adjustment plate and / or the connecting plate and / or the supporting plate are angle steel plates. Angle steel plates have excellent strength and rigidity and can withstand large pressure and tension. Using angle steel plates to make the adjustment plate, the connecting plate and / or the supporting plate enhances the overall structural strength of the device, enabling it to maintain stable performance even in harsh construction environments.

[0016] The following is further described in detail through specific implementation methods:

[0017] The reference numerals in the drawings of the specification include: adjustment plate 1, threaded hole 2, screw 3, first pin 4, connecting plate 5, second pin 6, rocker 7, bearing seat 8, reel 9, support plate 10, bolt 11, bearing 12.

[0018] Example 1 is basically as shown in the attached Figures 1 to 3As shown: A variable diameter manual bored pile lifting device includes a support frame, four connecting plates 5 and a lifting assembly. The support frame includes a base and a mounting seat, both of which are parallelogram in cross section. The mounting seat is located directly above the base and the centers of the two are on the same vertical line. The four corners of the mounting seat and the base correspond to each other and are connected by connecting plates 5. The connecting plates 5 are set at an angle, and the connection between the connecting plates 5 and the mounting seat and the base is a movable connection. Specifically, the base is composed of four retractable bottom plates, each of which is composed of two mutually detachably connected adjustment plates 1. The two adjustment plates 1 are provided with threaded holes 2, some of which are threadedly connected to screws 3. The two adjustment plates 1 are fixed by connecting the screws 3 to the threaded holes 2. By changing the hole position of the screw 3 and adjusting the overlapping part of the adjustment plates 1, the base range can be increased or decreased, thereby adapting to manual bored piles of different diameters. The mounting base is composed of four support plates 10 fixedly connected end to end. The connecting plate 5 is movably connected to the adjustment plate 1 and the support plate 10 through the first pin 4 and the second pin 6 respectively, forming a structure similar to a "live joint", ensuring that the connecting plate 5 can rotate freely within a certain range relative to the adjustment plate 1 and the support plate 10.

[0019] The lifting assembly is installed on the top of the mounting seat. Specifically, the lifting assembly includes a drum 9 and two fixed plates. The two fixed plates are fixedly connected to the two opposite support plates 10 by bolts 11. Bearing seats 8 are welded on the two support plates 10. Bearings 12 are installed in the bearing seats 8. The two bearings 12 are coaxial. The two bearings 12 are connected to the same rotating shaft. One end of the rotating shaft is connected to the rocker 7. The drum 9 mounting seat is on the rotating shaft and is located between the two bearings 12. A wire rope is provided on the drum 9. The end of the wire rope away from the drum 9 is fixedly connected to a hook. In the figure, the hook and the wire rope are not drawn.

[0020] The specific implementation process is as follows: When in use, according to the hole size of the bored pile, change the hole position of the bolt 11 to adjust the overlapping part of the adjustment plate 1, and use the screw 3 to connect the two adjustment plates 1 together to form a base of the required length / width. When transporting waste, lower the hook to the bottom of the bored pile. The operator uses the hook to hang the waste bucket containing the waste. Then, the operator manually turns the rocker 7 to drive the shaft to rotate, and the drum 9 rotates accordingly to start winding the wire rope. Under the lifting action of the wire rope, the hook and the waste bucket loaded with waste are slowly lifted out of the bored pile. When the waste bucket is lifted above the bored pile mouth, it is moved to the designated stacking location and the waste is unloaded. Then, the hook is lowered to the bottom of the bored pile again for the next waste transfer.

[0021] The only difference between Example 2 and Example 1 is that a motor is used to replace the rocker 7.

[0022] The above is only an embodiment of the present invention, and the commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
