Description

Technical Field

[0001] This invention belongs to the field of prefabricated building construction technology, and in particular relates to a main beam assembly device and assembly method for fiber composite material houses. Background Technology

[0002] Fiber composite materials can be designed according to structural needs to meet performance requirements that cannot be achieved by a single material. With the development of the construction industry, the requirements for the durability, low maintenance, and designability of traditional building materials continue to rise, which has led to the gradual increase in the popularity of fiber composite materials in the construction industry. Among them, the main beam is an important structure used to support the roof of fiber composite building materials.

[0003] During the assembly of the main beam of a building, a crane is needed to lift the main beam and move it to the assembly position. However, during the lifting and moving process, the main beam will twist and sway in the air, which will affect the accuracy of the main beam assembly position. The existing main beam assembly device does not have the function of reducing sway during the lifting of the main beam, which greatly increases the difficulty of assembly. Summary of the Invention

[0004] The purpose of this invention is to address the problems mentioned in the background art by providing a main beam assembly device and assembly method for fiber composite material houses.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a main beam assembly device for a fiber composite material house, comprising: a load-bearing beam, two sets of winches and two sets of anti-sway components.

[0006] Two sets of winches are symmetrically installed on the load-bearing beam. The output ends of both sets of winches are connected to steel wire ropes, and the lower ends of the steel wire ropes are connected to hooks.

[0007] Each anti-sway assembly includes a fixed box fixed to the bottom surface of the load-bearing beam. Two steel wire ropes pass through the two fixed boxes respectively. A mounting plate is rotatably connected inside the fixed box. Two guide wheels are rotatably connected to the surface of the mounting plate. The steel wire ropes pass through the two guide wheels in an "S" shape. A pin is fixed to the inner bottom surface of the fixed box. A deflection plate is rotatably connected to the pin. The deflection plate has a through hole through which the steel wire rope passes. The deflection plate is connected to the mounting plate through a gear transmission assembly. When the main beam twists and sways in the air, the mounting plate rotates back and forth, pulling the main beam vertically through the steel wire ropes, converting the torsional kinetic energy of the main beam into gravitational potential energy, thereby promoting the rapid stabilization of the main beam.

[0008] Furthermore, the gear transmission assembly includes an arc-shaped rack fixed to the end of the deflection plate, the center of which falls on the axis of the pin shaft. A worm gear is rotatably connected to the inner bottom surface of the fixed box, and a gear is fixed on the worm gear. The gear meshes with the arc-shaped rack. A worm wheel is rotatably connected to the inner wall of the fixed box, meshing with the worm gear. The worm wheel is fixed to the mounting plate.

[0009] Furthermore, the mounting plate has a groove extending along its length, in which two sliders slide and are slidably engaged. Two guide wheels are rotatably connected to the two sliders respectively. A bidirectional screw is rotatably connected in the groove, and the two sliders are respectively engaged with two sections of the bidirectional screw with opposite thread directions. A motor is mounted on the side wall of the mounting plate, and the output end of the motor is fixed to the bidirectional screw.

[0010] Furthermore, a pump cylinder is symmetrically fixed on the inner bottom surface of the fixed box about the deflection plate. A piston is slidably connected inside the pump cylinder. A piston rod is fixed on the piston. The piston rod is fixed to the side wall of the deflection plate. Both the pump cylinder and the piston rod adopt an arc-shaped structure and their center falls on the axis of the pin.

[0011] Furthermore, an oil storage box is provided on the outer wall of the fixed box, and the oil storage box contains lubricating oil. The input end of the pump cylinder is connected to the oil storage box through an oil inlet pipe. An oil passage is provided inside the piston rod, and an oil hole is provided on the piston that is connected to the input end of the oil passage. The output end of the oil passage is opened at the through hole.

[0012] Furthermore, it also includes a support frame and a moving track. There are two moving tracks, which are symmetrically laid on both sides of the house. The support frame is slidably mounted on the moving track, and the load-bearing beam is mounted on the support frame.

[0013] An assembly method for a main beam assembly device used in fiber composite building houses includes the following steps:

[0014] Step 1: Arrange the two moving tracks parallel to each other on both sides of the house, and place the support frame and load-bearing beam on the two moving tracks;

[0015] Step 2: Fix the two hooks to both ends of the main beam, and raise the main beam to a certain height using a winch;

[0016] Step 3: Control the support frame to move along the moving track and move the main beam laterally to the assembly position. During the lateral movement of the main beam, adjust the distance between the two guide wheels by the motor according to the amplitude of the main beam's deflection and sway, so that the main beam can be quickly stabilized.

[0017] Step 4: Use a winch to lower the stabilized main beam to the assembly position. After assembly, move the support frame and load-bearing beam back to the loading position along the moving track.

[0018] Step 5: Repeat steps 2-4. After assembling multiple main beams, disassemble the support frame and load-bearing beams from the moving track.

[0019] Compared with existing technologies, the advantages of the main beam assembly device and assembly method for this fiber composite material house are:

[0020] 1. This invention, by setting up guide wheels and gear transmission groups, uses the swing of the wire rope as the driving force when the main beam twists and sways during hoisting, causing the two guide wheels to deflect and misalign, reciprocating and tightening the wire rope, pulling the main beam to move in the vertical direction, converting the torsional kinetic energy of the main beam into gravitational potential energy, promoting the rapid stabilization of the main beam, and improving the accuracy of the main beam assembly position.

[0021] 2. By setting up a bidirectional screw, a slider, and a motor, the distance between the two guide wheels can be adjusted by the motor. That is, when the angle of the two guide wheels deflection remains unchanged, the winding and tightening length of the wire rope can be changed, thereby changing the vertical reciprocating displacement height of the main beam. When the sway amplitude is large, the distance between the two guide wheels can be increased, which can further improve the anti-sway effect on the main beam.

[0022] 3. This invention, by setting up a pump cylinder, an arc-shaped rod, and a piston, and using a deflection plate as the driving force, addresses the issue of severe wear on the wire rope when the main beam twists and sways, causing it to oscillate. The deflection plate drives the piston to reciprocate within the pump cylinder, continuously spraying lubricating oil onto the wire rope surface to reduce wear and extend its service life. This eliminates the need for an additional power unit, allowing the hoisting of the main beam, sway reduction, and lubrication of the wire rope to be carried out simultaneously.

Detailed Implementation

[0030] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0031] Example 1

[0032] like Figure 1-5 As shown, a main beam assembly device for a fiber composite house includes: a load-bearing beam 1, two sets of winches 2, two sets of anti-sway components, a support frame 26, and a moving track 22. The two sets of winches 2 are symmetrically installed on the load-bearing beam 1. The output ends of the two sets of winches 2 are connected to steel wire ropes 3, and the lower ends of the steel wire ropes 3 are connected to hooks 4. There are two moving tracks 22, which are symmetrically laid on both sides of the house. The support frame 26 is slidably set on the moving track 22, and the load-bearing beam 1 is erected on the support frame 26.

[0033] Each anti-sway assembly includes a fixed box 5 fixed to the bottom surface of the load-bearing beam 1, two steel wire ropes 3 passing through the two fixed boxes 5 respectively, a mounting plate 6 rotatably connected inside the fixed box 5, two guide wheels 7 rotatably connected to the surface of the mounting plate 6, the steel wire rope 3 passing around the two guide wheels 7 in an "S" shape, a pin 8 fixed to the inner bottom surface of the fixed box 5, a deflection plate 9 rotatably connected to the pin 8, a through hole 10 opened on the deflection plate 9, the steel wire rope 3 passing through the through hole 10, a slot for the steel wire rope 3 to pass through and swing on the bottom surface of the fixed box 5, and the deflection plate 9 being connected to the mounting plate 6 through a gear transmission group;

[0034] The gear transmission assembly includes an arc-shaped rack 11 fixed to the end of the deflection plate 9. The center of the arc-shaped rack 11 falls on the axis of the pin 8. A worm 12 is rotatably connected to the inner bottom surface of the fixed box 5. A gear 13 is fixed on the worm 12. The gear 13 meshes with the arc-shaped rack 11. A worm wheel 14 is rotatably connected to the inner wall of the fixed box 5. The worm wheel 14 meshes with the worm 12. The worm wheel 14 is fixed to the mounting plate 6.

[0035] When the main beam twists and sways during hoisting, it drives the wire rope 3 to reciprocate. The wire rope 3 drives the deflection plate 9 to reciprocate around the pin shaft 8. Since the gear 13 and the arc rack 11 mesh with each other, the worm 12 is driven to reciprocate. Since the worm wheel 14 meshes with the worm 12, the worm wheel 14 is driven to reciprocate. The worm wheel 14 drives the mounting plate 6 fixed to it to reciprocate. This causes the positions of the two guide wheels 7 to change alternately, which periodically winds, tightens and loosens the wire rope 3. In turn, the wire rope 3 pulls the main beam to move in the vertical direction, converting the torsional kinetic energy of the main beam into gravitational potential energy, promoting the rapid stabilization of the main beam and improving the accuracy of the main beam assembly position.

[0036] The mounting plate 6 has a groove 15 extending along its length. Two sliders 16 are slidably fitted in the groove 15. Two guide wheels 7 are rotatably connected to the two sliders 16 respectively. A bidirectional screw 17 is rotatably connected in the groove 15. The two sliders 16 are respectively engaged with two sections of the bidirectional screw 17 with opposite thread directions. A motor 18 is mounted on the side wall of the mounting plate 6. The output end of the motor 18 is fixed to the bidirectional screw 17.

[0037] During operation, the motor 18 drives the bidirectional screw 17 to rotate. Since the two sliders 16 are respectively engaged with the two sections of the thread of the bidirectional screw 17 with opposite thread directions, the two sliders 16 move closer or further away from each other, thereby adjusting the distance between the two guide wheels 7. That is, when the angle of the two guide wheels 7 deflection remains unchanged, the winding and tightening length of the wire rope 3 can be changed, thereby changing the vertical reciprocating displacement height of the main beam. When the sway amplitude is large, the distance between the two guide wheels 7 can be increased, which can further improve the anti-sway effect on the main beam.

[0038] A pump cylinder 19 is symmetrically fixed on the inner bottom surface of the fixed box 5 about the deflection plate 9. A piston 20 is slidably connected inside the pump cylinder 19. A piston rod 21 is fixed on the piston 20. The piston rod 21 is fixed to the side wall of the deflection plate 9. Both the pump cylinder 19 and the piston rod 21 adopt an arc-shaped structure and their center falls on the axis of the pin 8.

[0039] An oil storage box 23 is provided on the outer wall of the fixed box 5. The oil storage box 23 contains lubricating oil. The input end of the pump cylinder 19 is connected to the oil storage box 23 through the oil inlet pipe 24. An oil passage 25 is provided in the piston rod 21. An oil hole connected to the input end of the oil passage 25 is provided on the piston 20. The output end of the oil passage 25 is opened at the through hole 10. Both the input end and the output end of the pump cylinder 19 are provided with one-way valves, so that when the piston 20 moves back and forth in the pump cylinder 19, it can continuously draw out the lubricating oil in the oil storage box 23 and spray it out to the surface of the wire rope 3 through the oil passage 25.

[0040] When the main beam twists and sways, causing the wire rope 3 to swing, the wear on the wire rope 3 is quite severe. During the reciprocating deflection process, the deflector plate 9 drives the piston 20 to reciprocate within the pump cylinder 19 via the piston rod 21, which can continuously spray lubricating oil onto the surface of the wire rope 3 to reduce wear and extend its service life. No additional power device is required, so that the hoisting, sway reduction, and lubrication of the wire rope 3 can be carried out simultaneously.

[0041] The working principle is as follows:

[0042] When the main beam twists and sways during hoisting, it drives the wire rope 3 to reciprocate. The wire rope 3 drives the deflection plate 9 to reciprocate around the pin shaft 8. Since the gear 13 and the arc rack 11 mesh with each other, the worm 12 is driven to reciprocate. Since the worm wheel 14 meshes with the worm 12, the worm wheel 14 is driven to reciprocate. The worm wheel 14 drives the mounting plate 6 fixed to it to reciprocate. This causes the positions of the two guide wheels 7 to change alternately, which periodically winds, tightens and loosens the wire rope 3. In turn, the wire rope 3 pulls the main beam to move in the vertical direction, converting the torsional kinetic energy of the main beam into gravitational potential energy, promoting the rapid stabilization of the main beam and improving the accuracy of the main beam assembly position.

[0043] During operation, the motor 18 drives the bidirectional screw 17 to rotate. Since the two sliders 16 are respectively engaged with the two sections of the thread of the bidirectional screw 17 with opposite thread directions, the two sliders 16 move closer or further away from each other, thereby adjusting the distance between the two guide wheels 7. That is, when the angle of the two guide wheels 7 deflection remains unchanged, the winding and tightening length of the wire rope 3 can be changed, thereby changing the vertical reciprocating height of the main beam. When the sway amplitude is large, the distance between the two guide wheels 7 can be increased, which can further improve the anti-sway effect on the main beam.

[0044] When the main beam twists and sways, causing the wire rope 3 to swing, the wear on the wire rope 3 is quite severe. During the reciprocating deflection process, the deflector plate 9 drives the piston 20 to reciprocate within the pump cylinder 19 via the piston rod 21, which can continuously spray lubricating oil onto the surface of the wire rope 3 to reduce wear and extend its service life. No additional power device is required, so that the hoisting, sway reduction, and lubrication of the wire rope 3 can be carried out simultaneously.

[0045] Example 2

[0046] like Figure 6 As shown, based on Embodiment 1, the present invention provides an assembly method for a main beam assembly device applied to fiber composite material houses, comprising the following steps:

[0047] Step 1: Arrange the two moving tracks 22 parallel to each other on both sides of the house, and place the support frame 26 and the load-bearing beam 1 on the two moving tracks 22;

[0048] Step 2: Fix the two hooks 1 to both ends of the main beam, and raise the main beam to a certain height using the winch 2;

[0049] Step 3: Control the support frame 26 to move along the moving track 22 and move the main beam laterally to the assembly position. During the lateral movement of the main beam, adjust the distance between the two guide wheels 7 by the motor 18 according to the amplitude of the main beam's deflection and sway, so that the main beam can be quickly stabilized.

[0050] Step 4: The stabilized main beam is lowered to the assembly position by the winch 2. After the assembly is completed, the support frame 26 and the load-bearing beam 1 are moved again along the moving track 22 to the loading position.

[0051] Step 5: Repeat steps 2-4. After assembling the multiple main beams, remove the support frame 26 and the load-bearing beam 1 from the moving track 22.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
