Description

Technical Field

[0001] This invention relates to the field of lifting equipment technology, specifically to a remotely controlled lifting device for building construction. Background Technology

[0002] Lifting tools refer to the devices used in lifting machinery to lift heavy objects. The most commonly used lifting tools for lifting packaged goods are hooks and slings; others include lifting rings, lifting suction cups, clamps, and forks. They are widely used in the lifting and hoisting industry.

However, when the lifting equipment is too high or too far, it is impossible to check with the naked eye. Its functionality is relatively limited. Furthermore, when long materials are used in house construction, the lifting equipment cannot guarantee the stability of the materials, which makes the materials easy to tilt and slip, causing safety problems. At the same time, the weight of long materials makes unloading inconvenient. Summary of the Invention

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0029] Please see Figures 1 to 10The invention provides a technical solution: a remotely controlled lifting device for building construction, comprising a base plate 1, a long rod 2, a rotating rod 3, an I-beam column 4, a moving component 5, a telescopic rod 6, and a fixed plate 7. Two electrically controlled winding rollers 72 are installed inside the cavity of the fixed plate 7. Lifting ropes 71 are wound around both ends of the winding rollers 72. The lower ends of the lifting ropes 71 are fixed around the upper surface of the base plate 1, facilitating the winding of the lifting ropes 71 around the ends of the winding rollers 72. This allows for easy adjustment of the height of the base plate 1, where the lower ends of the lifting ropes 71 are fixed, facilitating material handling during roof construction. A fixed post 73 is fixed to the upper surface of the fixed plate 7. An annular groove is formed in the middle of the fixed post 73, and a rotating sleeve 74 is fitted around the outside of the fixed post 73. An annular locking block is fixed on the inner wall of the inner cavity, and the locking block engages in the locking groove. A lifting lug 75 is fixed above the outer end of the rotating sleeve 74 to facilitate the rotation of the base plate 1. The lifting lug 75 is connected to the hanger to facilitate the movement of the entire device in the air. A square hole 11 is opened in the middle of the base plate 1. Two long rods 2 are arranged in the inner cavity of the square hole 11. The long rods 2 are C-shaped. Two vertical limiting rods 22 are fixed at the upper end of the horizontal rod of the long rod 2. Limiting blocks 23 are fixed at the upper end of the two limiting rods 22. The two sides of the cross section of the limiting block 23 are inclined triangles. The width of the limiting block 23 is smaller than the width of the opening of the square hole 11 to facilitate the up and down movement of the limiting block 23 in the square hole 11. A round hole 21 is opened at the lower end of the two vertical rods of the long rod 2. Two cylinders 24 are threaded through the inner side of the connecting rod 32. The outer ends of the two inner cylinders 24 are hinged to the side ends of the connecting rod 32. Rotating rods 3 are hinged to the outer ends of the two outer cylinders 24. A notch 31 is provided at the upper end of the rotating rod 3, which is engaged with the lower end of the outer long rod 2, facilitating the rotation of the rotating rod 3 on the outer side of the lower end of the long rod 2. A fixing rod 34 is threaded through the outer end of the rotating rod 3 and the other end of the connecting rod 32. A limiting groove 33 is provided at the lower end of the inner side of the rotating rod 3, and the connecting rod 32 is engaged in the limiting groove 33, facilitating the angle change between the connecting rod 32 and the rotating rod 3. A fixing rod 34 is threaded through the end of the connecting rod 32 and the lower end of the rotating rod 3, and the fixing rod 34 is fixed to the inner wall of the square hole 11, facilitating the rotation of the rotating rod 3 and the connecting rod 3. The rotation of rod 2 facilitates the support of the two long rods 2. The other end of the connecting rod 32 is hinged to the lower end of the inner long rod 2 via a cylinder 24. An I-beam 4 is engaged at the lower middle end of the connecting rod 32. The two ends of the rotating shaft passing through the middle of the I-beam 4 are connected to the inner wall of the square hole 11 by bearings, facilitating the rotation of the I-beam 4 within the cavity of the square hole 11. The upper end of the eccentric column 41 fixed in the middle of the I-beam 4 abuts against the side of the connecting rod 32. An annular groove 42 is provided on the outer side of the rear end of the I-beam 4. A conveyor belt 43 is wound around the outer side of the two annular grooves 42. A motor is provided at the end of the rotating shaft of the outer end of the I-beam 4. The motor is started by the circular groove engaged in the side wall of the square hole 11, and the rear ends of the two I-beams 4 are connected to the conveyor belt 43.The conveyor belt 43 drives the two I-beams 4 to rotate together. The upper end of the eccentric column 41 abuts against the side of the connecting rod 32. The rotation of the I-beams 4 changes the distance between the connecting rod 32 and the rotating shaft, thus facilitating the rotation of the connecting rod 32 around the fixed rod 34. This facilitates the vertical movement of the two long rods 2. The rotating rod 3 allows the two long rods 2 to be staggered during vertical movement. The four limiting rods 22 move vertically at intervals, facilitating the movement of materials on the upper surface of the base plate 1. The two inclined surfaces of the limiting block 23 facilitate the movement of materials, thus facilitating the unloading of heavy materials.

[0030] Movable slots 12 are provided on the left and right sides of the base plate 1. A movable component 5 is slidably connected in the inner cavity of the movable slot 12. The movable component 5 moves outward to make the material more stable and prevent long materials from tilting left and right. The movable component 5 includes a support block 51, a movable rod 53, a sliding sleeve 54, and a turntable 56. The width of the support block 51 is the same as the width of the base plate 1, which facilitates widening the width of the base plate 1. A movable plate 52 is fixed to the inner side of the support block 51. The movable plate 52 is snapped into the movable slot 12. The cross-section of the movable plate 52 is the same as the cross-section of the opening of the movable slot 12, which facilitates the support of the support block 51 when it moves outward by abutting against the inner side of the movable slot 12. A movable rod 53 is hinged to a round rod within a groove in the surface, facilitating the rotation of the movable rod 53. Two protrusions are located on the upper and lower sides of the outer end of the movable rod 53, slidably connected to sliding sleeves 54 fixed at the upper and lower ends of the inner side of the movable groove 12. When the support block 51 moves left and right within the movable groove 12, it drives the two movable rods 53 to rotate, causing the two protrusions of the movable rods 53 to slide within the sliding sleeves 54, preventing the support block 51 from slipping off. This also facilitates adjustment of the distance between the two movable rods 53 and the bottom of the movable groove 12. A compression spring 55 is installed between the two movable rods 53, fixed between the movable plate 52 and the inner wall of the movable groove 12. The spring force of the compression spring 55 facilitates the retraction of the support block 51 into the movable groove 12. A turntable 56 is located in the middle, and a rotor 57 passes through the middle of the turntable 56. A motor that can be remotely controlled is located at the end of the rotor 57. The protrusion on the side of the turntable 56 facilitates changing the distance between the moving plate 52 and the rotor 57. By rotating the turntable 56, the distance between the support block 51 and the bottom of the moving groove 12 can be easily changed. This allows for adjustment of the distance between the two support blocks 51 according to materials of different lengths, ensuring the stability of the materials. At the same time, the elastic force of the compression spring 55 between the moving plate 52 and the moving groove 12 facilitates the return movement of the moving plate 52 and the reciprocating movement of the support block 51. A telescopic rod 6 is fixed to the outer side of the moving assembly 5. The telescopic rod 6 is fixed to the lower part of the outer side of the support block 51, and a spring 61 is wound around the rod of the telescopic rod 6. An L-shaped rod 62 is hinged to the outer end of the telescopic rod 6. Circular protrusions on both sides of the outer end of the telescopic rod 6 engage with the lower end of the L-shaped rod 62, allowing the lower end of the L-shaped rod 62 to rotate around the protrusions. A spring 61 rests between the support block 51 and the L-shaped rod 62. A T-shaped rod 63, fixed to the side of the moving assembly 5, is hinged to the middle of the L-shaped rod 62. The T-shaped rod 63 passes through a through hole 64 in the middle of the L-shaped rod 62. The crossbar of the T-shaped rod 63 is hinged to the inner side of the through hole 64, allowing the L-shaped rod 62 to rotate around the crossbar of the T-shaped rod 63. The spring force of the spring 61 causes the lower end of the L-shaped rod 62 to tilt outwards, while the upper end of the L-shaped rod 62 is pressed downwards. Pressing blocks 65 are hinged to two protrusions on the outer side of the upper end of the L-shaped rod 62.The lower surface of the pressing block 65 is serrated. The pressing block 65 presses downwards onto the material. The serrations on the lower surface of the pressing block 65 increase friction, thus facilitating the fixation of the material. This makes the material, which moves up and down, more stable on the upper part of the base plate 1, increasing construction safety. The elasticity of the spring 61 facilitates the disassembly of the material, thereby simplifying material handling.

[0031] The specific steps of this invention are as follows: In actual operation, two electrically controlled winding rollers 72 are provided in the inner cavity of the fixed plate 7, which facilitates the winding of the hanging ropes 71 wound around the two ends of the winding rollers 72, thereby facilitating the adjustment of the height of the base plate 1 fixed at the lower end of the hanging ropes 71, which is convenient for roof construction. The outer side of the fixed column 73 fixed on the upper surface of the fixed plate 7 is fitted with a rotating sleeve 74. The annular locking block fixed on the inner side wall of the inner cavity of the rotating sleeve 74 engages in the locking groove opened on the side of the fixed column 73, which facilitates the rotation of the rotating sleeve 74 on the outside of the fixed column 73, thereby facilitating the control of the rotation of the base plate 1. The lifting lug 75 fixed above the rotating sleeve 74 is connected to the hanger, thereby facilitating the movement of the entire device in the air.

[0032] Two long rods 2 are installed inside the square hole 11 in the middle of the base plate 1. Each of the two lower ends of the C-shaped long rods 2 has a round hole 21, through which a cylinder 24 passes. The outer ends of the two inner cylinders 24 are hinged to the side of the connecting rod 32. A rotating rod 3 is hinged to the outer end of each of the two outer cylinders 24. A notch 31 at the upper end of the rotating rod 3 engages with the outer side of the long rod 2, facilitating the rotation of the rotating rod 3. The other end of the rotating rod 3 is connected to the connecting rod... The other end of 32 has a fixing rod 34 fixed to the inner side of the square hole 11, which facilitates the rotation of the rotating rod 3 and the connecting rod 32 and also provides support for the two long rods 2. The lower end of the inner side of the rotating rod 3 and the connecting rod 32 that are in contact with each other is provided with a limit groove 33 to facilitate the rotation of the connecting rod 32. The lower end of the middle of the connecting rod 32 is engaged with an I-beam 4. The two ends of the rotating shaft passing through the middle of the I-beam 4 are connected to the inner side wall of the square hole 11 with bearings to facilitate the rotation of the I-beam 4 in the square hole 11. The two I-beams rotate within the cavity. An annular groove 42 is provided on the outer side of the rear end of the I-beam 4. A conveyor belt 43 is wound around the outer side of the two annular grooves 42. When the motor is started, which is engaged in the circular groove in the side wall of the square hole 11, the two I-beams 4 rotate together through the conveyor belt 43. The upper end of the eccentric column 41 fixed in the middle of the I-beam 4 abuts against the side of the connecting rod 32. The rotation of the I-beam 4 changes the distance between the connecting rod 32 and the rotating shaft, thereby facilitating the rotation of the connecting rod 32 around the fixed rod 34 as the rotation axis. This facilitates the up and down movement of the two long rods 2. The rotating rod 3 facilitates the staggering of the two long rods 2 when they move up and down. The upper ends of the two limiting rods 22 fixed at the upper end of the long rods 2 are each fixed with a limiting block 23. The four limiting rods 22 move up and down at intervals, facilitating the movement of materials on the upper surface of the base plate 1. The two inclined surfaces of the limiting block 23 facilitate the movement of materials, thereby facilitating the unloading of heavy materials.

[0033] The base plate 1 has movable grooves 12 on its left and right sides. A movable component 5 is slidably connected in the inner cavity of the movable groove 12. The movable component 5 moves outward to make the material more stable and prevent long materials from tilting to the left or right. The movable component 5 includes a support block 51, a movable rod 53, a sliding sleeve 54, and a turntable 56. The support block 51 facilitates the gathering of materials and makes it easier for the materials to settle. A movable plate 52 fixed to the inner side of the support block 51 is snapped into the movable groove 12. When the support block 51 moves outward, the side of the movable plate 52 abuts against the inner side of the movable groove 12 for support. A movable rod 53 is hinged to a round rod in a groove on the inner side of the movable plate 52. Two protrusions on the upper and lower sides of the outer end of the movable rod 53 are slidably connected to the inner side of the movable groove 12. The upper and lower ends of the sliding sleeve 54 are fixed to prevent the support block 51 from falling out of the moving groove 12, and at the same time facilitate the rotation of the moving rod 53. A turntable 56 is provided between the moving plate 52 and the inner side wall of the moving groove 12. The rotor 57 passing through the middle of the turntable 56 is provided with a motor that can be remotely controlled. The side of the turntable 56 is provided with a protrusion that abuts against the inner side of the moving plate 52. By rotating the turntable 56, the distance between the moving plate 52 and the rotor 57 can be easily changed, thereby easily changing the distance between the two support blocks 51. This makes it easy to adjust the distance between the two support blocks 51 according to materials of different lengths, so as to ensure the stability of the materials. At the same time, the elastic force of the compression spring 55 provided between the moving plate 52 and the moving groove 12 facilitates the return of the moving plate 52 and facilitates the reciprocating movement of the support block 51.

[0034] A telescopic rod 6 is fixed to the lower part of the outer side of the support block 51. Circular protrusions on both sides of the outer end of the telescopic rod 6 engage with the lower end of the L-shaped rod 62, facilitating rotation of the lower end of the L-shaped rod 62. A spring 61 is wound around the body of the telescopic rod 6, resting between the support block 51 and the L-shaped rod 62. A T-shaped rod 63 passes through the through hole 64 in the middle of the L-shaped rod 62. The crossbar of the T-shaped rod 63 is hinged to the inner side of the through hole 64, allowing the L-shaped rod 62 to rotate around the crossbar of the T-shaped rod 63. The spring force of the spring 61 causes the lower end of the L-shaped rod 62 to tilt outwards. The upper end of the L-shaped rod 62 is provided with... The two protrusions hinged pressing blocks 65 press down on the material. The lower surface of the pressing blocks 65 is provided with serrations to increase friction and thus facilitate the fixing of the material. The spring force of the spring 61 facilitates the disassembly of the material. The device can control the height of the base plate 1 by remotely controlling the rotation of the winding roller 72. The distance between the two support blocks 51 can be adjusted by controlling the rotation of the rotor 57 to facilitate the stability of the material. The rotation of the motor at the end of the conveyor belt 43 can be controlled to limit the material. At the same time, the material can be pushed by the staggered up and down movement of the two long rods 2, thus facilitating the unloading of the material.
