Description

Technical Field

[0001] This invention relates to the field of building pile foundation construction technology, specifically to a steel cage hoisting device for bored pile construction. Background Technology

[0002] The hoisting of the reinforcing cage for pile foundations is a crucial construction procedure that directly affects the bearing capacity and structural safety of the pile foundation. During hoisting, the reinforcing cage is typically secured to one end with steel cables, and then lifted as a whole from that end. Initially, because it is lifted from the end, the other end of the reinforcing cage inevitably gets dragged on the ground. This hoisting method not only causes friction damage to the ground but also, due to the cage's length, easily leads to localized stress and deformation, ultimately affecting the construction quality of the pile and failing to meet the user's requirements. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a rebar cage hoisting device for bored pile construction that is easy to hoist and can effectively reduce the deformation of the rebar cage due to hoisting, thus solving the technical problem of rebar cage deformation during hoisting.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A steel cage hoisting device for bored pile construction includes a frame, an angle adjustment module, and two sets of clamping components. The two sets of clamping components are symmetrically installed at both ends of the frame, and the angle adjustment module is installed in the middle of the frame. The clamping assembly includes a drive module and a clamping module. Both the drive module and the clamping module are fixedly installed on the frame, with the clamping module located at the end of the frame. The drive module and the clamping module are connected. The clamping module includes a body, several limiting guide wheels, a first gripper, and a second gripper. The body has an arc-shaped structure, and two rows of limiting guide wheels are installed inside the body. Both rows of limiting guide wheels are arc-shaped, forming an arc-shaped movement space between them. The first gripper and the second gripper are both arc-shaped structures. The second gripper is located on the side of the first gripper closer to the frame, and both the first and second grippers are adapted to the arc-shaped movement space. The first and second grippers are located in the arc-shaped movement space, and the two rows of limiting guide wheels abut against the inner and outer sides of the first and second grippers, respectively. The outer ends of the first and second grippers are provided with drive teeth. The first and second grippers are engaged with the drive module through the drive teeth. The drive module can synchronously drive the first and second grippers to extend and retract within the body.

[0006] Furthermore, the drive module includes a drive motor, a drive bevel gear, a first transmission mechanism, and a second transmission mechanism. The drive motor is fixedly mounted on the frame, and the drive bevel gear is rotatably mounted on the front end of the drive motor via a rotating shaft. The first transmission mechanism includes a transmission sleeve, a first bevel gear, a first drive gear, and a drive shaft. One end of the transmission sleeve is sleeved on the output shaft of the drive motor and the two are fixedly connected. One end of the drive shaft is inserted into the other end of the transmission sleeve and the two are fixedly connected. The other end of the drive shaft passes through the second transmission module and the first drive gear is installed at the end of the drive shaft. The first drive gear meshes with the drive teeth on the outside of the first gripper. The first bevel gear is installed at the end of the transmission sleeve near the drive motor and meshes with the drive bevel gear. The second transmission mechanism includes a second bevel gear, a connecting sleeve, and a second drive gear. The second bevel gear and the second drive gear are respectively located at both ends of the connecting sleeve. The connecting sleeve is rotatably mounted on the frame via bearings. The drive shaft passes through the connecting sleeve. The second bevel gear meshes with the drive bevel gear, and the second bevel gear and the first bevel gear are symmetrically arranged at the drive bevel gear. The second drive gear meshes with the drive teeth on the outer side of the second gripper.

[0007] Furthermore, the angle adjustment module includes a mounting base, a connecting base, and two electric winches. The mounting base is fixedly installed in the middle of the frame, and the connecting base is hinged to the mounting base via a pivot. An electric winch is installed on each of the two sides of the connecting base away from the clamping assembly, and the winches of the two electric winches are fixedly connected to both ends of the frame.

[0008] Furthermore, a lifting ring is provided at the top of the connecting seat.

[0010] Furthermore, a limit block is provided on the side of the tip of the first gripper near the second gripper, and a limit block is provided on the side of the tip of the second gripper near the first gripper.

[0011] Compared with the prior art, the present invention provides a steel cage hoisting device for bored pile construction, which has the following beneficial effects: The rebar cage hoisting device for this type of pile foundation construction is installed at the crane. Two clamping components at both ends of the frame horizontally clamp the rebar cage, causing the drive module to engage the clamping modules and hold the cage in place. The crane then lifts the device and the rebar cage off the ground. Next, the angle adjustment module adjusts the orientation of the frame and the clamped rebar cage, bringing it to a vertical position for placement at the pile hole for foundation pouring. This device allows for stable hoisting of the rebar cage, preventing dragging on the ground and effectively reducing damage to both the ground and the cage, thus improving the quality of the pile foundation pouring.

[0014] 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.

[0015] Please see Figures 1 to 3 This embodiment provides the following technical solution: A steel cage hoisting device for bored pile construction includes a frame 11, which is the main supporting and connecting component of the device. The device also includes an angle adjustment module and two sets of clamping components. The two sets of clamping components are symmetrically installed at both ends of the frame 11. Through the synergistic effect of the clamping components, the hoisting range of the steel cage can be increased, making the device more stable in clamping the steel cage. The angle adjustment module is installed in the middle of the frame 11 and is used to adjust the hoisting angle of the frame 11 and the steel cage to facilitate the installation of the steel cage. The clamping assembly includes a drive module 3 and a clamping module 4. Both the drive module 3 and the clamping module 4 are fixedly installed on the frame 11, with the clamping module 4 located at the end of the frame 11. The drive module 3 is connected to the clamping module 4. The drive module 3 is used to drive the clamping module 4 to work, and the clamping module 4 is used to clamp and fix the steel cage. The clamping module 4 includes a body 41, several limiting guide wheels 42, a first gripper 43, and a second gripper 44. The body 41 has an arc-shaped structure, and two rows of limiting guide wheels 42 are installed inside the body 41. Both rows of limiting guide wheels 42 are arc-shaped, forming an arc-shaped movement space between them. The first gripper 43 and the second gripper 44 are both arc-shaped. The second gripper 44 is located on the side of the first gripper 43 closest to the frame 11, and both the first gripper 43 and the second gripper 44 are adapted to the arc-shaped movement space. The first gripper 43 and the second gripper 44 are both located in the arc-shaped movement space. The guide rollers 42 abut against the inner and outer sides of the first gripper 43 and the second gripper 44, respectively. Under the cooperative limiting action of the two rows of guide rollers 42, the two arc-shaped grippers can move in an arc-shaped movement space. The two grippers, together with the machine body 41, can surround and clamp the steel cage. The outer ends of the first gripper 43 and the second gripper 44 are provided with drive teeth. The first gripper 43 and the second gripper 44 are connected to the drive module 3 through the drive teeth. The drive module 3 can synchronously drive the first gripper 43 and the second gripper 44 to move in and out of the machine body 41 through the meshing transmission with the drive teeth.

[0016] The drive module 3 includes a drive motor 31, a drive bevel gear 35, a first transmission mechanism, and a second transmission mechanism. The drive motor 31 is fixedly mounted on the frame 11. The drive bevel gear 35 is rotatably mounted on the front end of the drive motor 31 via a rotating shaft. The output shaft of the drive motor 31 is connected to the first transmission mechanism. The drive motor 31 can drive the drive bevel gear 35 and the first gripper 43 to move through the first transmission mechanism. The drive bevel gear 35 can drive the second gripper 44 to move through the second transmission mechanism. The first transmission mechanism includes a transmission sleeve 32, a first bevel gear 33, a first drive gear 34, and a drive shaft 39. One end of the transmission sleeve 32 is sleeved on the output shaft of the drive motor 31 and the two are fixedly connected. One end of the drive shaft 39 is inserted into the other end of the transmission sleeve 32 and the two are fixedly connected. The drive motor 31 can drive the drive shaft 39 to rotate through the transmission sleeve 32. The other end of the drive shaft 39 passes through the second transmission module and the first drive gear 34 is installed at the end of the drive shaft 39. The drive shaft 39 can drive the first drive gear 34 to mesh with the drive teeth of the first gripper 43. The first bevel gear 33 is installed at the end of the transmission sleeve 32 near the drive motor 31. The first bevel gear 33 meshes with the drive bevel gear 35. The first bevel gear 33 on the transmission sleeve 32 can mesh with the drive bevel gear 35 and rotate. The second transmission mechanism includes a second bevel gear 36, a connecting sleeve 37, and a second drive gear 38. The second bevel gear 36 and the second drive gear 38 are respectively located at both ends of the connecting sleeve 37, allowing them to rotate synchronously. The connecting sleeve 37 is rotatably mounted on the frame 11 via bearings. The drive shaft 39 passes through the connecting sleeve 37, allowing the first drive gear 34 at the end of the drive shaft 39 and the second drive gear 38 at the end of the connecting sleeve 37 to rotate separately. The second bevel gear 36 meshes with the drive bevel gear 35, and the second bevel gear 36 and the first bevel gear 33 are symmetrically arranged at the drive bevel gear 35, so that the first drive gear 34 and the second drive gear 38 rotate in opposite directions. The second drive gear 38 meshes with the drive teeth on the outer side of the second gripper 44, allowing the second drive gear 38 to extend and retract at the machine body 41; the first gripper 43 and the second gripper 44 can then move synchronously in opposite directions.

[0017] The angle adjustment module includes a mounting base 12, a connecting base 13, and two electric winches 2. The mounting base 12 is fixedly installed in the middle of the frame 11. The connecting base 13 is hinged to the mounting base 12 via a pivot, allowing the connecting base 13, the mounting base 12, and the machine body 41 to swing relative to each other. An electric winch 2 is installed on each side of the connecting base 13 away from the clamping assembly. The winches of the two electric winches 2 are fixedly connected to both ends of the frame 11. Through the synergistic action of the two electric winches 2, the angle between the connecting base 13 and the frame 11 can be changed, thereby changing the hoisting angle of the steel cage clamped at this device.

[0018] The top of the connecting seat 13 is provided with a lifting ring, which is used to connect with the slings of the crane.

[0019] The ends of the first gripper 43 and the second gripper 44 furthest from the body 41 are triangular tips, which serve as guides to facilitate the gripping of the steel cage by the two grippers.

[0020] A limiting block 45 is provided on the side of the tip of the first gripper 43 near the side of the second gripper 44, and a limiting block 45 is provided on the side of the tip of the second gripper 44 near the side of the first gripper 43. The tips of the two grippers can extend and move to contact the limiting block 45. Under the action of the limiting block 45, the two grippers can be prevented from detaching from the body 41.

[0021] The specific implementation process is as follows: When using the steel cage hoisting device for this pile construction, first fix the sling of the crane to the lifting ring at the top of the connecting seat 13, then install the device at the crane, and then use the device to hoist the steel cage. When hoisting the reinforcing cage, the device is moved above the cage using a crane, then released to bring it close to the cage. Next, the drive motors 31 of the two clamping components are activated. The drive motors 31 drive the first bevel gear 33 and the first drive gear 34 to rotate via the transmission sleeve 32 and drive shaft 39. The first bevel gear 33 drives the drive bevel gear 35 to rotate, and the drive bevel gear 35 drives the second drive gear 38 to rotate via the connecting sleeve 37. The first drive gear 34 and the second drive gear 38 can then rotate in opposite directions. The second drive gear 38 can drive the first gripper 43 and the second gripper 44 to extend out of the machine body 41 respectively. The two grippers can grab and fix the steel cage through their action. Then the crane lifts the device and the steel cage off the ground to a certain height. Then the two electric winches 2 are started, so that one of the two electric winches tightens the connecting cable as needed and the other releases the connecting cable. This allows the frame 11 and the steel cage to be gradually driven and adjusted from a horizontal state to a vertical state, moving the steel cage to the predetermined position. The two clamping components can then slowly release the steel cage, thus completing one hoisting operation of the steel cage.

[0022] The steel cage hoisting device for this type of pile foundation construction is installed at the crane. Two clamping components located at both ends of the frame 11 horizontally clamp the steel cage, causing the drive module 3 to drive the clamping module 4 to hold the steel cage. Then, the crane lifts the device and the steel cage off the ground. Next, the angle adjustment module drives the frame 11 and the clamped steel cage to adjust their orientation angle, so that the steel cage becomes vertical and can be placed at the pile hole for pile foundation pouring operations. This device can stably hoist the steel cage, avoiding dragging it on the ground, effectively reducing damage to the ground and the steel cage, and improving the quality of pile foundation pouring.
