Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an auxiliary device for hoisting and aligning prefabricated components of coastal low-rise buildings. Background Technology

[0002] With the rapid development of my country's mechanical technology, my country has gradually shifted from light processing to heavy processing. In the heavy processing production process, since the various parts produced or used are large in size and heavy in weight, hoisting equipment is often used for assistance, mainly for assembling the various parts and inspecting the various parts.

[0003] Lifting refers to the general term for the installation and positioning of equipment using cranes or hoisting mechanisms. During maintenance or repair, various lifting tools are used to lift equipment, workpieces, tools, materials, etc., causing them to change position. Lifting is a specific term used for equipment positioning. Lifting generally requires the use of lifting slings or hoisting equipment, which are manufactured by specialized companies.

[0004] When hoisting precast wall panels onto the upper floors of mid-rise buildings, the alignment and positioning are currently done manually. This operation is labor-intensive for workers, poses certain safety risks, and is prone to installation errors. Furthermore, precast wall panels typically weigh 2-3 tons, making manual operation inconvenient. Therefore, this paper proposes an auxiliary device for hoisting and aligning precast wall panels in mid-rise buildings along the coast to address these issues. Utility Model Content

One end of the pull rope is detachably connected to the top of the precast wall panel via a hook, and the other end passes through the fixed pulley and the constraint sleeve in sequence before being connected to the drum drive of the winch. The winch is fixed to the bottom surface of the receiving frame by bolts. The constraint sleeve is fixed to the side of the receiving frame near the fixed pulley by bolts, and is on the same side as the precast wall panel, to limit the lateral displacement of the pull rope.

[0008] Preferably, a limiting groove is provided on the side of the receiving frame near the hinge seat, and a limiting block is rotatably connected in the limiting groove via a rotating shaft. The limiting block is rotatably connected to a rotating locking block via a rotating shaft. The rotating locking block can be rotated to be perpendicular to the top surface of the receiving frame and used to abut the bottom end of the precast wall panel.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides the following technical solution: an auxiliary device for hoisting and aligning prefabricated components of a coastal low-rise building, including a hoisting device 1, a prefabricated wall panel 2 and an alignment auxiliary unit. The alignment auxiliary unit is movably connected below the hoisting device 1, and the prefabricated wall panel 2 is fixedly installed on the top of the alignment auxiliary unit. The hoisting device 1 is a crane, and its hook is detachably connected to the top lifting ring of the prefabricated wall panel 2, which is used to lift the prefabricated wall panel 2, weighing 2-3 tons, to the top surface of the inclined support frame 8.

[0023] The alignment auxiliary unit includes a mobile vehicle body 3, a support frame 8, a diagonal brace hydraulic cylinder 11, a support hydraulic cylinder 12, a pull rope 16, a winch 17, and a constraint sleeve 18. The bottom of the mobile vehicle body 3 is rotatably connected to casters 4 via bearings. The casters 4 are equipped with a braking mechanism and are locked via an operating panel 5 to ensure the device remains stationary during alignment operations. The top is bolted to the operating panel 5, guardrail 6, and handrail 7. One end of the support frame 8 is rotatably connected to the front top of the mobile vehicle body 3 via a hinge seat 9, and the other end is bolted to a fixed pulley 10. The operating panel 5 is electrically connected to the diagonal brace hydraulic cylinder 11, the support hydraulic cylinder 12, and the winch 17 via control lines to control the angle adjustment of the support frame 8, the support and fixation of the mobile vehicle body 3, and the lifting and lowering of the precast wall panel 2. One end of the diagonal brace hydraulic cylinder 11 is movably connected to the center of the bottom surface of the support frame 8 via a hinge shaft, and the other end is bolted to the top surface of the mobile vehicle body 3. The support hydraulic cylinder 16... The pressure cylinder 12 is vertically fixed to the top rear end of the mobile vehicle body 3 by bolts, and the bottom end of its piston rod abuts against the precast wall panel 2. One end of the pull rope 16 is detachably connected to the top end of the precast wall panel 2 by a hook, and the other end passes through the fixed pulley 10 and the constraint sleeve 18 in sequence and is connected to the drum drive of the winch 17. The winch 17 is fixed to the bottom surface of the receiving frame 8 by bolts. The constraint sleeve 18 is fixed to the side of the receiving frame 8 near the fixed pulley 10 by bolts and is on the same side as the precast wall panel 2. It is used to limit the lateral displacement of the pull rope 16. A limit groove 13 is opened on the side of the receiving frame 8 near the hinge seat 9. A limit block 14 is rotatably connected in the limit groove 13 by a rotating shaft. A rotating block 15 is rotatably connected to the limit block 14 by a rotating shaft. The rotating block 15 can be rotated to be perpendicular to the top surface of the receiving frame 8 and abuts against the bottom end of the precast wall panel 2. After the rotating block 15 is retracted, it can be embedded in the receiving cavity of the limit block 14.

[0024] In use, the first step is to control the inclined support hydraulic cylinder 11 via the control panel 5 to tilt the support frame 8. Then, the lifting equipment 1 transfers the precast wall panel 2 onto the tilted support frame 8. The rotating block 15 is manually operated to make it perpendicular to the support frame 8 and abut against the bottom of the precast wall panel 2. At the same time, the top of the precast wall panel 2 is connected to the pull rope 16 via a hook. Next, the moving vehicle 3 is moved to the target installation position via the casters 4. The control panel 5 controls the lowering support hydraulic cylinder 12 to abut against the wall. Then, the inclined support hydraulic cylinder 11 is adjusted to turn the support frame 8 into a vertical position. At this time, the winch 17 is started to pull the pull rope 16, which pulls the precast wall panel 2 upward a short distance via the fixed pulley 10. At the same time, the rotating block 15 is manually retracted into the receiving cavity of the limiting block 14. Finally, the precast wall panel 2 is slowly lowered to complete the alignment and installation. During the process, the constraint sleeve 18 is used to limit the deviation of the pull rope 16, and the guardrail 6 and handrail 7 ensure operational safety.
