Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated component hoisting, and in particular to a prefabricated component hoisting, assembling and adjusting device and method. Background Art

[0002] With the rapid development of my country's construction industry, prefabricated construction has been widely adopted in the construction field, and the demand for lifting and hoisting large components during construction is also increasing. Currently, when lifting prefabricated components in my country, single or dual cranes are often used. After the prefabricated components are tied, they are lifted vertically. After that, the lifting equipment may need to be replaced or repositioned. Then, the prefabricated components are installed using construction methods such as rotation, sliding, and delivery.

[0003] When lifting prefabricated parts, existing cranes need to first lift one end of the prefabricated part placed horizontally on the ground using two steel wire ropes, one long and one short, and then slowly lift the other end of the prefabricated part upwards to leave the ground, so that the prefabricated part is in an inclined state, and then use the crane to lift the prefabricated part to the installation location.

[0004] However, the following problems still exist in this process:

[0005] After one end of the prefabricated component is lifted, the bottom edge of the other end of the prefabricated component will continue to contact the ground and be subjected to force, which will cause the bottom edge of the prefabricated component to partially break. When hoisted to the installation location, since the hoisting angle of the prefabricated component is inconsistent with the actual installation angle, the installation positioning of the prefabricated component often requires manual continuous adjustment. At the same time, repeated adjustments of the position will also damage the contact point between the prefabricated component and the wall structure, reducing the efficiency and accuracy of the installation.

[0027] 1. The present invention can adjust the installation angle of the prefabricated stairs during the lifting process through the adjustment component and the locking component. After the installation angle is adjusted, the prefabricated stairs can always be kept at the installed inclination angle by cutting off the power supply, which can reduce energy consumption while achieving the installation and positioning of the stairs, avoiding the problem of low efficiency caused by manual adjustment requiring a lot of time, improving construction efficiency and avoiding the problem of damage to the edges of the prefabricated stairs.

[0029] 3. The positioning assembly is provided to facilitate the positioning and installation of the prefabricated stairs. Specifically, when the prefabricated stairs are hoisted above the installation platform, the multi-stage telescopic rod is first activated to insert the cylinder composed of multiple arc-shaped plates into the installation hole. The initial diameter of the cylinder composed of multiple arc-shaped plates is smaller than the diameter of the installation hole. When the prefabricated stairs shake, it can also be accurately inserted into the installation hole. After the arc-shaped plate is inserted into the installation hole, the second motor is started. The second motor drives the two shafts to rotate through the fourth pulley. The rotation of the shaft drives the round block to rotate. The rotation of the round block drives the slide bar to move in the arc groove at the same time. At the same time, it will also drive the slide plate to slide along the connecting slide groove, thereby expanding the multiple curved plates, and expanding the curved plates to the same diameter as the installation hole, which is convenient for the installation of the prefabricated stairs. Through the setting of the auxiliary positioning component, the positioning component is used to enable the prefabricated stairs to position the four installation holes at the same time. According to the position of the reserved steel bars, the clamped multiple curved plates are moved, and the multiple curved plates are aligned with the reserved steel bars, so that the installation holes can be aligned with the reserved steel bars, thereby improving the positioning accuracy and eliminating the problem of edge damage caused by manual installation of prefabricated stairs during assembly.

[0065] Example 2: A method for hoisting, assembling and adjusting a prefabricated component, using the prefabricated component hoisting, assembling and adjusting device described in Example 1, comprising the following steps:

[0066] S1: First, install the auxiliary positioning assembly on the installation platform 40, and then clean the dust and sand on the surface of the installation platform 40.

[0067] S2: Place the adjustment plate 33 on the prefabricated staircase 2, then screw the tightening block 34 into the lifting hole of the prefabricated staircase 2, level it through the leveling assembly, connect the connecting ring 37 to the connecting lifting ring 35, and then control the first motor 3 to lift the staircase.

[0068] S3: Start the first motor 3 to adjust the inclination angle of the stairs, and then hoist the prefabricated stairs 2 to the installation location.

[0069] S4: Start the positioning component to preliminarily locate the installation position of the prefabricated staircase 2, and use the auxiliary positioning component to accurately locate and install the prefabricated staircase 2.

[0070] The working principle of the prefabricated part hoisting and assembly adjustment device of the present invention is: when in use, first place the adjusting plate 33 on the lifting hole of the prefabricated stair 2 so that the bottom of the tightening block 38 is in close contact with the prefabricated stair 2, and then screw the tightening block 34 into the lifting hole through the adjusting plate 33. When the adjusting plate and the adjusting plate 33 are in contact, it means that the installation of the tightening block 34 is completed. Then put the connecting ring 37 into the inside of the connecting lifting ring 35, and then start the crane to lift the prefabricated stair 2. During lifting, the prefabricated stair 2 is in a horizontal state. When it is lifted to a certain height, start the first motor 3 and the electromagnet 7. The electromagnet 7 attracts the iron rod 8 so that the iron rod 8 squeezes the spring 10 away from the disc 5, and the first motor 3 drives the reduction gear set 4 to rotate, and the reduction gear set 4 The output end of the rod drives the long rod to rotate, and the long rod drives the first pulley 11 to rotate, and then drives the second pulley 12 and the third pulley 13 to rotate, so that the two rotating rollers 14 rotate in the same direction. When the rotating roller 14 rotates, it drives the movable pulley 16 on the left to rise and the movable pulley 16 on the right to fall. The height of the two ends of the prefabricated stairs 2 is measured according to the height sensor on the adjustment plate 33. When the height of the two ends reaches the required angle for installation, the first motor 3 and the electromagnet 7 are manually controlled to be powered off at the same time, or the first motor 3 and the electromagnet 7 can be controlled to stop running at the same time by the controller. At this time, the electromagnet 7 loses its magnetism, thereby causing the spring 10 to rebound and the block 6 at one end of the iron rod 8 to approach the disc 5, so that the block 6 is stuck in the slot of the disc 5, thereby The disc 5 is fixed and limited. After the disc 5 is limited, the reduction gear set 4 can be fixed, so that the first motor 3 and the electromagnet 7 of the prefabricated staircase 2 can maintain the inclination angle of the prefabricated staircase 2 when it is to be installed when the power is off, thereby reducing energy consumption. The prefabricated staircase 2 with the installation angle adjusted is then hoisted to the installation platform 40, and the multi-stage telescopic rod 39 is first started to insert the cylinder composed of multiple curved plates 28 into the installation hole. The initial diameter of the cylinder composed of multiple curved plates 28 is smaller than the diameter of the installation hole. When the prefabricated staircase 2 shakes, it can also be accurately inserted into the installation hole. After the curved plate 28 is inserted into the installation hole, the second motor 19 is started. The second motor 19 drives the two rotating shafts to rotate through the fourth pulley 21, and the rotation of the rotating shaft drives the round block 23 The round block 23 rotates, and the rotation drives the slide bar 24 to move in the arc groove 25, and at the same time drives the slide plate 27 to slide along the connecting slide groove 26, thereby expanding the plurality of arc plates 28, so that the arc plates 28 are expanded to the same diameter as the mounting hole. When the plurality of arc plates 28 are expanded and inserted into the mounting hole, a part of the arc plates 28 will be exposed outside the mounting hole. At this time, the first electric push rod 42 is started, and the first electric push rod 42 drives the second electric push rod 44 to move downward. When it reaches the appropriate position, the second electric push rod 44 is started to push forward so that the plurality of arc plates 28 are located inside the two arc clamping plates 46, and then the third electric push rod 48 is started to clamp the plurality of arc plates 28. Then, according to the position of the reserved steel bars, the clamped plurality of arc plates 28 are moved.The multiple curved plates 28 are aligned with the reserved steel bars, so that the installation holes can be aligned with the reserved steel bars, thereby improving the positioning accuracy and eliminating the problem of the prefabricated stairs 2 being damaged by manual installation during assembly.
