Abstract

This invention relates to a high-altitude precision alignment and installation device for prefabricated building components, comprising a support base plate, a hollow shell, a winding shaft, a traction rope, a traction plate, a lower angle iron, a guide brace, a fixed base, an adjusting positioning sleeve, and an adjusting screw. A traction power sleeve drives a reduction bevel gear set to move the winding shaft and release the traction rope, achieving horizontal traction of the component. A positioning power sleeve drives a flat-speed bevel gear set to rotate the adjusting screw, causing the adjusting positioning sleeve to slide along the support base plate. This, in conjunction with a telescopic sleeve and telescopic connecting rod, allows for vertical and attitude fine-tuning of the component.

Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a high-altitude precision alignment and installation device for prefabricated building components. Background Technology

[0002] When steel structure components are installed at height, tower cranes typically lift steel beams and columns to near their designed positions, and then fine-tune their horizontal and vertical alignment manually using prying or hand-operated hoists. This traditional method has the following problems: the high precision required for steel component connections makes manual alignment difficult to meet; the heavy weight of the components makes repeated lifting and adjustment time-consuming and inefficient; and workers operating below the suspended components at height pose significant safety hazards.

[0003] Existing technologies include solutions such as jack adjustment, limit baffle assistance, or pulley block fine adjustment, but these are mostly designed for concrete components and have poor adaptability to the precise alignment of steel components. They also generally suffer from problems such as limited adjustment functions and lack of coordinated linkage between traction and positioning systems, making it difficult to achieve efficient and precise alignment at the end of steel structure installation. Therefore, in order to address the above problems, a high-altitude precision alignment and installation device for prefabricated building components is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a high-altitude precision alignment and installation device for prefabricated building components to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-altitude precision alignment and installation device for prefabricated building components includes a support base, a hollow shell, a traction plate, and guide braces. The hollow shell is fixedly connected to the side of the support base. The hollow shell includes a mounting shell, a support frame, and a top shell, which are sequentially fixedly connected. A transmission shell is fixedly connected to the end of the top shell away from the support base. A winding shaft is rotatably connected to the inner side of the hollow shell. A winding transmission rod is fixedly sleeved on the inner side of the winding shaft and rotatably connected to the inner side of the hollow shell. A traction rope is provided on the outer side of the winding shaft. A traction plate is fixedly connected to the end of the traction rope away from the winding shaft. A traction positioning sleeve is fixedly connected to the side of the support base facing the traction plate. A lower angle iron is fixedly connected to the bottom side of the support base. A guide brace is fixedly connected to the lower angle iron. A fixed base is fixedly connected to the support base on the side of the lower angle iron facing the top of the support base. An adjusting positioning sleeve is slidably connected to the inner side of the support base. An adjusting screw that is rotatably connected to the fixed base is threaded onto the inner side of the adjusting positioning sleeve.

[0007] Preferably, the support frame surrounds the periphery of the winding shaft, the winding transmission rod is located between the mounting shell and the top shell, and one end of the winding transmission rod passes through the top shell and extends outward, and the traction positioning sleeve is located at the axial extension position of the winding transmission rod.

[0008] Preferably, a traction power sleeve is rotatably connected to the side of the transmission housing, and a reduction bevel gear set is provided inside the transmission housing. The reduction bevel gear set includes a large reduction gear and a small reduction gear that mesh with each other. The large reduction gear of the bevel gear is attached to the top shell, and the axis of the large reduction gear of the bevel gear is fixedly connected to the winding transmission rod that penetrates the top shell. The small reduction gear is fixedly connected to the traction power sleeve.

[0009] Preferably, the bracket base plate and the hollow shell are fixedly connected to an upper angle iron on the same side. One end of the upper angle iron is rotatably connected to a limiting side frame. A guide hole is provided in the limiting side frame, and the traction rope is passed through the guide hole.

[0010] Preferably, a fixing ring is fixedly connected to the side of the traction plate facing the support base plate. The fixing rings are symmetrically distributed on the traction plate. One of the fixing rings is sleeved on the outside of the traction rope and fixedly connected, and a traction hole hook is fixedly connected to the other fixing ring.

[0011] Preferably, the fixed base is rotatably connected to symmetrically arranged telescopic sleeves, and the inner side of the telescopic sleeves is slidably connected to telescopic connecting rods. The top ends of the two sets of telescopic connecting rods are respectively rotatably connected to the adjusting positioning sleeve.

[0012] Preferably, a positioning power sleeve is rotatably connected to the right side of the fixed base, and a flat-speed bevel gear set is provided on the inner side of the fixed base. The two bevel gears of the flat-speed bevel gear set that mesh with each other are fixedly connected to the adjusting screw and the positioning power sleeve respectively through a transmission component.

Furthermore, the use of mechanical traction instead of manual pushing and pulling reduces the number of repeated lifting and adjustment operations, significantly improving construction efficiency. Moreover, operators do not need to work below the suspended components, effectively avoiding the risk of components falling and injuring people, ensuring high safety. Attached Figure Description

[0029] 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.

[0030] Example 1

[0031] Please see Figures 1-12 The present invention provides a technical solution:

[0032] A high-altitude precision alignment and installation device for prefabricated building components includes a support base plate 1, a perforated outer shell 2, a traction plate 5, and a guide brace 13. The support base plate 1 is made of high-strength stainless steel plate with a thickness of 8-12mm. The perforated outer shell 2 is fixedly connected to the side of the support base plate 1 by high-strength bolts. The perforated outer shell 2 includes a mounting shell 201, a support frame 202, and a top shell 203, which are fixedly connected in sequence. The mounting shell 201 is fixed to the side of the support base plate 1 by bolts. The support frame 202 extends outward. A transmission shell 7 is fixedly connected to the end of the top shell 203 away from the support base plate 1. The transmission shell 7 is a closed box structure with a reduction transmission component inside and an anti-rust coating on the outside.

[0033] The inner side of the hollow outer shell 2 (i.e., the space enclosed by the mounting shell 201 and the support frame 202) is rotatably connected to a winding shaft 3 via bearings. The winding shaft 3 has a hollow cylindrical structure, and a winding transmission rod 301 is fixedly sleeved on its inner side. Both ends of the winding transmission rod 301 are rotatably connected to the inner wall of the hollow outer shell 2 via ball bearings. Specifically, one end of the winding transmission rod 301 is mounted on the mounting shell 201 via a bearing, and the other end extends through the top shell 203 and into the transmission shell 7. The outer surface of the winding shaft 3 is circumferentially machined with spiral grooves for uniformly winding the traction rope 4. The traction rope 4 is made of high-strength synthetic fiber rope (such as Dyneema rope) or 6mm diameter stainless steel wire rope. One end is fixed to the winding shaft 3, and the other end passes through several guide members and is fixedly connected to the traction plate 5.

[0034] A traction positioning sleeve 21 is fixedly connected to the side of the support base plate 1 facing the traction plate 5. The traction positioning sleeve 21 is a cylindrical metal sleeve fixed on the support base plate 1. The axis of the traction positioning sleeve 21 is on the same axis as the axis of the winding transmission rod 301, that is, the traction positioning sleeve 21 is located at the axial extension position of the winding transmission rod 301.

[0035] The support frame 202 surrounds the winding shaft 3. The support frame 202, composed of multiple uprights forming a cage-like protective structure, prevents the traction rope 4 on the winding shaft 3 from swinging or slipping off the groove during high-speed winding and unwinding. The winding drive rod 301 is located between the mounting housing 201 and the top housing 203, with one end of the drive rod 301 penetrating the top housing 203 and extending outwards. A sealing ring and dust cover are installed at the penetration point to prevent dust from entering the drive housing 7.

[0036] A traction power sleeve 9 is rotatably connected to the side of the transmission housing 7 via a bearing seat. The outer end of the traction power sleeve 9 is machined with an internal hexagonal hole or an external hexagonal head for quick connection to the output shaft of a hand crank, a rechargeable electric wrench, or a pneumatic motor. A reduction bevel gear set 8 is housed within the transmission housing 7, comprising a meshing reduction gear 801 and a reduction pinion 802. The gear ratio between the reduction gear 801 and the reduction pinion 802 is 3:1 to 5:1 to achieve speed reduction and torque increase. The back of the reduction gear 801 is fitted against the upper surface of the top housing 203, and friction is reduced via a thrust bearing. The axis of the reduction gear 801 is fixedly connected to the winding transmission rod 301, which penetrates the top housing 203, via a spline. The reduction pinion 802 is fixedly connected to the inner end of the traction power sleeve 9 via a flat key. When the external power drives the traction power sleeve 9 to rotate, the reduction pinion 802 drives the reduction gear 801 to rotate, which in turn drives the winding transmission rod 301 and the winding shaft 3 to rotate, thereby realizing the winding and unwinding of the traction rope 4.

[0037] To further guide the direction of the traction rope 4, an upper angle iron 10 is fixedly connected to the support base plate 1 and the hollow shell 2 on the same side. The upper angle iron 10 is made of L-shaped angle steel, with its vertical surface welded to the side of the support base plate 1 and its horizontal surface facing outward. One end of the upper angle iron 10 is rotatably connected to a limiting side frame 11 via a pin. The limiting side frame 11 is an angle steel frame with a guide hole inside, into which a wear-resistant ceramic ring or a quenched steel sleeve is embedded. The traction rope 4 passes through this guide hole. By adjusting the rotation angle of the limiting side frame 11, the direction of the traction rope 4 can be adapted, making it suitable for hoisting building components of different heights.

[0038] The traction plate 5 is made of 10mm thick aluminum alloy or steel plate, and a fixing ring 501 is fixedly connected to the side facing the support base plate 1. There are two fixing rings 501, symmetrically distributed at the top and bottom ends or left and right sides of the traction plate 5. One fixing ring 501 is sleeved on the outside of the traction rope 4 and fixedly connected by a clamping sleeve and a locking nut, so that the end of the traction rope 4 is firmly connected to the traction plate 5. A traction hole hook 6 is fixedly connected to the other fixing ring 501. The traction hole hook 6 is used to insert into the bolt fastening hole of the steel structure beam. Rubber pads can also be attached to the side of the traction plate 5 to prevent noise or damage to the surface of the component from hard collisions.

[0039] The actual working process of this device during traction is as follows: The support base plate 1 is attached to the flange plate of the steel column. The traction positioning sleeve 21 is inserted into the bolt hole slot of the steel column, and the traction hook 6 is inserted into the bolt fastening hole of the steel structure beam to be lifted and installed. Ensure that the traction rope 4 passes smoothly through the guide hole of the limiting side frame 11, and check that the fixing ring 501 on the traction plate 5 is not loose. The traction power sleeve 9 is continuously driven, and the reduction bevel gear set 8 drives the winding shaft 3 to rotate at a uniform speed. The traction rope 4 is gradually wound up, and the hoisted steel beam moves towards the installation position of the steel column. During the movement, due to the limiting effect of the traction positioning sleeve 21, the traction rope 4 remains in a straight line and does not swing. Simultaneously, the limiting side frame 11 adaptively rotates with the angle change of the traction rope 4 to avoid rope wear. When the steel beam is lifted to the steel column connection point close to the target installation height, traction is stopped, and the component is suspended. The device is then disassembled after the repositioning and installation adjustment described in Example 2.

[0040] Example 2

[0041] Please see Figures 1-12 Based on Example 1, this example further illustrates the repositioning and adjustment process of the device when the component is precisely aligned at high altitude.

[0042] A lower angle iron 12 is fixedly connected to the bottom side of the support base plate 1. The lower angle iron 12 is a right-angle steel, with one side welded to the support base plate 1 and the other side extending horizontally outward. A guide brace 13 is fixedly connected to the upper part of the lower angle iron 12, and the guide brace 13 and the lower angle iron 12 together form a stable triangular support and guide system. A fixing base 14 is also provided on the side of the lower angle iron 12 facing the top of the support base plate 1. The fixing base 14 is a rectangular steel shell, which is fixedly connected to the support base plate 1 by bolts or welding. The interior of the fixing base 14 is hollow to accommodate the transmission gear set.

[0043] A vertical groove is formed on the inner side of the support base plate 1. The adjusting positioning sleeve 15 is slidably disposed within the vertical groove. The main body of the adjusting positioning sleeve 15 is a cylindrical slider, and two limiting rings are fixedly connected to its outer surface. The two limiting rings are respectively disposed on both sides of the support base plate 1 (i.e., one on the front of the support base plate 1 and one on the back), forming a clamping structure to prevent the adjusting positioning sleeve 15 from falling out of the groove or tilting during sliding. An internal threaded hole is formed in the center of the adjusting positioning sleeve 15, which cooperates with the adjusting screw 18 that vertically penetrates the adjusting positioning sleeve 15.

[0044] The upper end of the adjusting screw 18 is rotatably connected to the support frame 202 via a bearing, and the lower end is rotatably connected to the fixed base 14 via a ball bearing. The adjusting screw 18 passes through the internal threaded hole of the adjusting positioning sleeve 15, forming a helical transmission pair. When the adjusting screw 18 rotates, the adjusting positioning sleeve 15 moves up and down along the vertical slide groove.

[0045] A positioning power sleeve 20 is rotatably connected to the operator-facing end of the fixed base 14 via a bearing. The outer end of the positioning power sleeve 20 also has an internal hexagonal socket for connecting a hand crank or torque wrench. A flat-speed bevel gear set 19 is located on the inner side of the fixed base 14. The flat-speed bevel gear set 19 consists of two bevel gears of the same size and with the same number of teeth (speed ratio 1:1) to ensure that the rotation angle of the adjusting screw 18 matches the rotation angle of the positioning power sleeve 20, facilitating precise control of the fine-tuning by the operator. The two meshing bevel gears of the flat-speed bevel gear set 19 are fixedly connected to the lower end of the adjusting screw 18 and the inner end of the positioning power sleeve 20 respectively via a drive shaft. When the positioning power sleeve 20 is rotated, power is transmitted to the adjusting screw 18 via the flat-speed bevel gear set 19, driving the screw to rotate.

[0046] To improve the stability and load-bearing capacity of the adjusting positioning sleeve 15 during lifting and lowering, two symmetrically arranged telescopic sleeve rods 16 are rotatably connected to the fixed base 14. The telescopic sleeve rods 16 are square steel tubes, with their lower ends rotatably connected to the left and right sides of the fixed base 14 via hinge supports. Each telescopic sleeve rod 16 has a telescopic connecting rod 17 slidably connected to its inner side. The telescopic connecting rod 17 is a solid steel rod with a diameter smaller than that of the telescopic sleeve rod 16, and its surface is coated with grease. The top ends of the two sets of telescopic connecting rods 17 are rotatably connected to the left and right sides of the adjusting positioning sleeve 15 via hinge supports. When the adjusting positioning sleeve 15 moves up and down, the telescopic structure formed by the telescopic sleeve rods 16 and the telescopic connecting rods 17 automatically adjusts its length and changes its tilt angle, always providing auxiliary support and lateral constraint for the adjusting positioning sleeve 15, preventing it from twisting or jamming due to the weight of the component.

[0047] The top end of the adjusting screw 18 is connected to the support frame 202 via a rotary joint. This rotary joint allows the adjusting screw 18 to rotate freely but restricts its axial movement, thereby ensuring that the verticality of the screw is not affected by the component's eccentric load.

[0048] The working process of this device during the repositioning and adjustment is as follows: The positioning power sleeve 20 is rotated in the forward or reverse direction, and the flat-speed bevel gear set 19 drives the adjusting screw 18 to rotate in the same direction. The adjusting screw 18 drives the adjusting positioning sleeve 15 to slowly rise or fall along the vertical slide groove. The moving speed of the adjusting positioning sleeve 15 is determined by the screw pitch and rotation speed, and is usually 2~4mm per revolution. During the adjustment process, the telescopic sleeve 16 and telescopic connecting rod 17 extend and retract accordingly, ensuring the stability of the position of the adjusting positioning sleeve 15. According to the specific position of the bolt mounting holes of the steel column, after the traction positioning sleeve 21 is inserted into one of the bolt mounting holes, the operator can adjust the extension end of the positioning sleeve 15 to adapt to bolt mounting holes with different hole spacings. After alignment, the external drive tool is connected to the positioning power sleeve 20. First, the adjusting screw 18 is rotated to drive the adjusting positioning sleeve 15 to slowly rise along the vertical slide until it can no longer move. At this time, the traction positioning sleeve 21 and the adjusting positioning sleeve 15 are fixed in the two sets of corresponding bolt mounting holes of the steel column connecting plate. Then, the connection operation between the component and the main building is carried out.

[0049] After the traction and lifting in Example 1 is completed, the component is suspended approximately 20-50mm from the installation position. After the operator confirms that the component is roughly aligned, the external drive tool is connected to the positioning power sleeve 20 to release and disassemble the device.
