Description

Technical Field

[0001] The invention belongs to the technical field of concrete prefabricated component installation, in particular to a concrete prefabricated component installation device used in shallow water areas. Background Art

[0002] Precast concrete parts are widely used in water conservancy projects and marine projects such as bridges, docks, and dams, with the advantages of fast construction speed, controllable quality, and low environmental impact. However, when installing precast concrete parts in shallow water areas (such as rivers, lakes, coastlines, etc.), the construction difficulty increases significantly due to factors such as shallow water depth, water flow and wave effects, complex foundation conditions, and environmental sensitivity, which puts higher requirements on the performance of the installation device.

[0003] For example, the utility model with publication number CN217461321 U discloses an integrated assembled structure of a prefabricated elevator concrete structure. The utility model relates to the technical field of prefabricated elevator assembly. The integrated assembled structure of the prefabricated elevator concrete structure, through the setting of the positioning component, rotates the inner slide until the inner slide is rotated through the rotating shaft to be perpendicular to the prefabricated base, and then the corresponding limit plate is inserted through the slide groove until the positioning plate fixedly installed on its top surface is kept in contact with the top surface of the back wall panel, and then the positioning block and the prefabricated base are positioned by bolts, so that the assembly of the back wall panel can be completed, and the shaft can be connected and cast through subsequent measurement, and the side wall panels and door wall panels are assembled separately, thereby ensuring the assembly stability of the connecting parts and avoiding the influence on the assembly of the casting parts, thereby improving the convenience of disassembly and installation and the stability of shaft casting.

[0004] The common concrete prefabricated parts installation devices on the market usually use large ships or floating platforms as carriers and are equipped with heavy lifting equipment for lifting. During the lifting process, the holes at the bottom of the prefabricated parts need to be docked and connected with the steel frame on the base. However, due to the limited construction space in shallow water areas and the large buoyancy of the water surface, during the installation process, the base is easy to move with the buoyancy of the water surface. At the same time, the top lifting is easily affected by wind and waves and shakes when lifting through cables, making it difficult to achieve alignment between the base and the prefabricated parts. Manual support and calibration are required, with low operating efficiency and lack of adaptability to complex foundation conditions in shallow water areas, resulting in insufficient stability during the installation process.

[0005] Therefore, a precast concrete component installation device for shallow water areas is proposed to solve the problems raised by the background technology. Summary of the invention

[0006] In order to solve the problems raised in the above background technology, the present invention provides a precast concrete component installation device for shallow water areas.

[0011] Preferably, a moving rod is fixedly provided at the bottom of each of the plurality of adjusting blocks, and a round hole is provided on one side of each of the plurality of adjusting blocks away from the clamping block.

[0012] Preferably, the bottom of the installation box is provided with a plurality of movable grooves distributed in a circular array, the side wall of the installation box is provided with a plurality of notches corresponding to the movable grooves, and the adjustment block and the movable rod are slidably engaged with the notches and the movable grooves respectively.

[0014] Preferably, the driving disk is circular in shape and one side of the outer wall is provided with a plurality of grooves distributed in a circular array, and the outermost end of the driving disk can abut against the adjustment block.

[0015] Preferably, the reset assembly includes a connecting column fixedly arranged at the top position of the side of the plurality of adjustment blocks away from the clamping block, a plurality of steel ropes fixedly sleeved on the connecting column, and a winding drum fixedly arranged on the top of the driving disk and fixedly connected to the driving rod, the steel rope is wound around the winding drum and one end of the steel rope away from the connecting column is fixed on the winding drum.

[0016] Preferably, a spring is sleeved in the circular hole, and the spring is in a circular ring shape.

[0017] Preferably, the calibration assembly includes a vertical plate slidably arranged inside the multiple slide grooves, a limit plate fixedly arranged on the top of the vertical plate and engaged with the limit groove, an insert block fixedly installed on the bottom of the vertical plate, a push plate fixedly arranged on one side of the multiple vertical plates close to the base and in contact with the base, and a push plate fixedly arranged on the vertical plate and fixedly connected to the push plate.

[0018] Preferably, a lifting assembly is provided at the bottom of the bracket, and the lifting assembly is used to drive the adjustment of the height of the installation box.

[0019] Preferably, the lifting assembly includes a connecting plate fixedly arranged on the top of the mounting box and rotatably connected to the driving rod, a plurality of electric cylinders fixedly arranged on the top of the connecting plate, and a fixed circular plate fixedly arranged on the top of the plurality of electric cylinders and fixedly connected to the bracket, and the connecting plate is fixedly connected to the motor.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention facilitates the clamping and fixing of prefabricated bodies of different sizes by setting up the coordination of structures such as the clamping plate, the installation box and the driving assembly. The control box controls the clamping mechanism at the bottom of the bracket to clamp the prefabricated body. The driving assembly drives the clamping blocks to separate from each other, which is convenient for placing the prefabricated body at the bottom of the clamping block. Then the resetting assembly drives the clamping plates to approach each other to quickly clamp the prefabricated body. The driving assembly can adjust the clamping range according to the size of the prefabricated body. The motor drives the driving rod and the driving disk to rotate. The irregular shape of the driving disk causes the protruding part to squeeze the adjusting block, driving the clamping block and the clamping plate to separate, thereby adapting to prefabricated bodies of different sizes. This solves the problem that the existing device is not convenient for rapid fixation and calibration, and is prone to positional displacement during the hoisting and docking process.

[0022] The present invention facilitates the resetting of the clamp block and achieves the effect of rapid clamping by setting the coordination of the connecting column, steel rope and winding drum and other structures. After the adjustment is completed, in order to achieve stable clamping, the adjustment block can be quickly reset by the reset assembly. The specific steps are as follows: start the motor to rotate in the opposite direction, and the driving disk is reset accordingly, so that its concave side moves to the vicinity of the adjustment block. During the rotation of the driving disk, the steel rope on the winding drum begins to wind up, pulling the connecting column closer to the winding drum, thereby driving the adjustment blocks to move closer to each other along the notch. At this time, the bottom clamp approaches the prefabricated body and clamps it. In this process, the spring changes from an extended state to a contracted state, ensuring that the clamping process is stable and reliable.

[0023] The present invention facilitates the rapid calibration and installation of the prefabricated body and the base by setting up the coordination of structures such as the vertical plate, the push plate and the electric push rod. The calibration assembly is used to ensure that the base and the prefabricated body remain in a stable position during the docking process. First, the control box is moved to the vicinity of the base by the pulley, and then the clamped prefabricated body is lifted by the lifting assembly. At this time, the vertical plate slides down along the slide under the action of gravity, and is prevented from falling off by the coordination of the limit groove and the limit plate, so that the plug at the bottom is inserted into the soil around the base to achieve preliminary fixation. Then, the electric push rod is started to synchronously push multiple push plates toward the base. Since the top of the push plate contacts the prefabricated body, it can be ensured to remain in a horizontal state, so that each side of the base and the prefabricated body are aligned to complete the calibration. This process not only achieves precise alignment, but also avoids shaking during subsequent docking through reasonable clamping, ensuring that the installation process is stable and reliable.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 9 As shown, the present invention provides a precast concrete installation device for shallow water areas, comprising a control box 1, a universal wheel arranged at the bottom of the control box 1, and a bracket 11 fixedly arranged at the top of the control box 1, and further comprising:

[0036] A clamping mechanism 4, which is installed on one side of the bracket 11, and a preform body 2 and a base 3 are provided at the bottom. The clamping mechanism 4 is used to install and align the preform body 2 and the base 3;

[0037] The clamping mechanism 4 includes a plurality of clamping blocks 41 distributed in a circular array, a mounting box 42 disposed on the top of the clamping block 41, a driving component 43 located inside the mounting box 42 for adjusting the clamping block 41, a reset component 44 disposed inside the mounting box 42 for resetting and clamping the clamping block 41, and a calibration component 46 installed at the bottom of the clamping block 41 for limiting the base 3;

[0038] The bottoms of the multiple clamping blocks 41 are fixedly connected with clamping plates 411, the tops of the multiple clamping blocks 41 are fixedly connected with adjusting blocks 412, the adjusting blocks 412 slide along the inside of the installation box 42, the tops of the multiple clamping blocks 41 are provided with sliding grooves 413, the bottoms of the clamping blocks 41 are provided with limiting grooves 414, the limiting grooves 414 are connected with the sliding grooves 413 and have a T-shaped cross-section.

[0039] The above scheme is adopted: when in use, the base 3 is first placed in a shallow water area where the prefabricated body 2 needs to be reinforced, the control box 1 is controlled to clamp the prefabricated body 2 using the clamping mechanism 4 at the bottom of the bracket 11, and the clamping blocks 41 are driven away from each other by the driving component 43, so as to facilitate the placement of the prefabricated body 2 at the bottom of multiple clamping blocks 41. At this time, the reset component 44 is used to reset the adjustment block 412, thereby driving the clamping plates 411 to approach each other to quickly clamp the prefabricated body 2, and then moving it to the top of the base 3, and cooperating with the calibration component 46 to calibrate the position of the prefabricated body 2 and the base 3, so as to ensure that the position of the prefabricated body 2 and the base 3 is not offset during the downward placement process, so as to facilitate accurate insertion.

[0040] like Figures 5 to 8 As shown, a moving rod 4121 is fixedly provided at the bottom of each of the multiple adjustment blocks 412, a round hole 4122 is provided on one side of each of the multiple adjustment blocks 412 away from the clamping block 41, a plurality of moving grooves 421 distributed in a circular array are provided at the bottom of the installation box 42, a plurality of notches 422 corresponding to the moving grooves 421 are provided on the side wall of the installation box 42, and the adjustment blocks 412 and the moving rod 4121 are slidably engaged with the notches 422 and the moving grooves 421, respectively;

[0041] The driving assembly 43 includes a driving disk 431 rotatably arranged at the center of the installation box 42, a driving rod 432 fixedly arranged on the top of the driving disk 431 and rotatably connected to the top of the installation box 42, and a motor 433 fixedly arranged on the top of the driving rod 432. The driving disk 431 is circular in shape and has a plurality of grooves 4311 distributed in a circular array on one side of its outer wall. The outermost end of the driving disk 431 can abut against the adjustment block 412.

[0042] The reset assembly 44 includes a connecting column 441 fixedly arranged at the top position of the side away from the clamping block 41 of the multiple adjustment blocks 412, a plurality of steel ropes 442 fixedly sleeved on the connecting column 441, and a winding drum 443 fixedly arranged on the top of the driving disk 431 and fixedly connected to the driving rod 432. The steel rope 442 is wound around the winding drum 443 and one end away from the connecting column 441 is fixed to the winding drum 443. A spring 45 is sleeved in the circular hole 4122, and the spring 45 is in a circular ring shape.

[0043] The above scheme is adopted: the position of the adjustment block 412 is adjusted by using the driving assembly 43. When the preform body 2 needs to be clamped, the motor 433 can be used to drive the driving rod 432 and the driving disk 431 to rotate according to the size of the preform body 2. Since the driving disk 431 is an irregular shape, when the protruding side of the driving disk 431 rotates to the side close to the adjustment block 412, it will squeeze the adjustment block 412 to drive the adjustment block 412 to slide along the notch 422, and the bottom moving rod 4121 slides along the moving groove 421, thereby driving the bottom clamping block 41 and the clamping plate 411 to move away from each other, thereby expanding the clamping range and facilitating the clamping of preform bodies 2 of different sizes;

[0044] When the adjustment is completed, in order to achieve reasonable clamping, the adjustment block 412 can be quickly reset by facilitating the reset component 44 to achieve the clamping effect. The motor 433 rotates in the opposite direction to drive the drive disk 431 to reset so that one side of the recess moves to the side position of the adjustment block 412. During the rotation of the drive disk 431, the steel rope 442 wound on the winding disk 443 is driven to reel in, thereby pulling the connecting column 441 closer to the position of the winding disk 443, thereby driving the adjustment block 412 to approach each other along the groove 422, and driving the bottom clamp 411 to approach the preform body 2 to clamp and fix it. During this process, the spring 45 is transformed from an extended state to a contracted state.

[0045] like Figure 2 As shown, the calibration component 46 includes a vertical plate 461 slidably set inside a plurality of slide grooves 413, a limit plate 4611 fixedly set on the top of the vertical plate 461 and engaged with the limit groove 414, an insert block 462 fixedly installed on the bottom of the vertical plate 461, a push plate 463 fixedly set on one side of the plurality of vertical plates 461 close to the base 3 and in contact with the base 3, and a push plate 463 fixedly set on the vertical plate 461 and fixedly connected to the push plate 463.

[0046] The above scheme is adopted: the calibration of the base 3 and the prefabricated body 2 is achieved through the calibration component 46 to ensure that the two maintain unchanged positions during the alignment process, the control box 1 is moved to the position of the base 3 by using the pulley, and the clamped prefabricated body 2 is lifted by cooperating with the lifting component 47. At this time, the bottom vertical plate 461 slides downward along the slide groove 413 under the action of its own gravity, and will not fall due to the action of the limit groove 414 and the limit plate 4611, so that the bottom plug block 462 is inserted into the soil around the base 3. At this time, the electric push rod 464 is driven to make multiple electric push rods 464 synchronously drive multiple push plates 463 to push close to the base 3. Since the top position of the push plate 463 is in contact with the prefabricated body 2, it can maintain a horizontal state with it, and then it can drive the base 3 to be flush with each side of the prefabricated body 2, so as to achieve the calibration effect, and at the same time, the prefabricated body 2 and the base 3 are reasonably clamped to avoid shaking during subsequent docking.

[0047] like Fig. 9 As shown, a lifting assembly 47 is provided at the bottom of the bracket 11, and the lifting assembly 47 is used to drive the adjustment of the height of the installation box 42. The lifting assembly 47 includes a connecting plate 471 fixedly provided on the top of the installation box 42 and rotatably connected to the driving rod 432, a plurality of electric cylinders 472 fixedly provided on the top of the connecting plate 471, and a fixed circular plate 473 fixedly provided on the top of the plurality of electric cylinders 472 and fixedly connected to the bracket 11, and the connecting plate 471 is fixedly connected to the motor 433.

[0048] The above scheme is adopted: the prefabricated body 2 and the base 3 are stably docked through the lifting assembly 47, and the connecting plate 471 is driven downward by the electric cylinder 472, so that the clamping block 41 and the clamped prefabricated body 2 move downward synchronously. In order to maintain stability, the clamping plate is clamped at the center position of the prefabricated body 2, and the prefabricated body 2 and the base 3 remain in position during the downward process, thereby ensuring that the holes on the prefabricated body 2 are accurately docked with the steel bars on the base 3.

[0049] The working principle and use process of the present invention are as follows: when using the device, first place the base 3 at the predetermined casting position, start the motor 433 according to the size of the prefabricated body 2, and the drive rod 432 and the drive disk 431 rotate accordingly. Since the drive disk 431 has an irregular shape, when the protruding portion approaches the adjustment block 412, it will push the adjustment block 412 to slide along the notch 422. At the same time, the bottom moving rod 4121 moves along the moving groove 421 to separate the bottom clamping block 41 and the clamping plate 411, thereby expanding the clamping range and completing the adjustment. After the adjustment is completed, the reset assembly 44 resets the multiple adjustment blocks 412 to ensure that the prefabricated body 2 is firmly clamped. After clamping is completed, the universal wheel at the bottom of the control box 1 is used to move the preform body 2 to the top of the base 3, and the vertical plate 461 descends under the action of gravity, and the push plate 463 and the electric push rod 464 are used to calibrate the position of the base 3. After the calibration is completed, the electric cylinder 472 pushes the preform body 2 down so that it can be docked and installed with the base 3. During this process, the vertical plate 461 slides upward along the slide groove 413 to ensure smooth installation.
