DETAILED DESCRIPTION

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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. Specific embodiment one:

[0032] See also Figure 1-6 As shown, the utility model is a lifting frame for indoor construction, comprising a base 1, a swivel seat 2, a lifting frame 3, and a lifting platform 4. The swivel seat 2 is rotatably mounted on the base 1 via a first bearing 8. One end of the lifting frame 3 is hinged to the swivel seat 2 via a hinge seat. The other end of the lifting frame 3 is hinged to the lifting platform 4 via a hinge seat. A first motor 5 for driving the lifting platform 4 to rise and fall is mounted on the swivel seat 2. The first motor 5 is a reduction motor with a brake. An eccentric wheel 6 is mounted on the conveying shaft of the first motor 5. The outer circumference of the eccentric wheel 6 abuts against the bottom of the lifting frame 3. A second motor 7 for driving the swivel seat 2 to rotate is mounted on the base 1. The second motor 7 is a reduction motor with a brake. A first control switch 9 for controlling the forward and reverse rotation of the first motor 5 is mounted on the lifting platform 4. A second control switch 10 for controlling the forward and reverse rotation of the second motor 7 is mounted on the lifting platform 4.

[0033] In this embodiment, a construction lifting frame that can move circumferentially and up and down is formed by combining a base 1, a swivel seat 2, a lifting frame 3 and a lifting platform 4. The height of the lifting platform 4 is adjusted by a first motor 5, and the direction of the lifting platform 4 is adjusted by a second motor 7. The two cooperate to meet the needs of large-scale construction.

[0034] The base 1 includes a horizontal base plate 11 placed on the ground. A shaft 12 for mounting a first bearing 8 is fixed to the center of the upper surface of the horizontal base plate 11. A motor mounting base 13 for mounting a second motor 7 is also fixed to the upper surface of the horizontal base plate 11. A gear 71 is mounted on the output shaft of the second motor 7.

[0035] The swivel base 2 includes a cylinder 21 that is connected to and engages with the first bearing 8. A square tube 22 is fixed to the top of the cylinder 21. An external gear disc 23 is fixed to the outer wall of the cylinder 21, meshing with the gear 71. The first motor 5 is mounted on a side wall of the square tube 22. The output shaft of the first motor 5 extends through the square tube 22 and rotates with the square tube 22. The eccentric wheel 6 is placed within the square tube 22 and is mounted to the output shaft of the first motor 5 via a key. A horizontal extension rod 24 is fixed to an adjacent side wall of the square tube 22. A portal 25 is fixed to the end of the horizontal extension rod 24. A universal wheel 26 is mounted at the lower end of each of the two columns of the portal 25. When the base 1 is placed on the ground, the universal wheel 26 contacts the ground. The surface of the hinge between the square tube 22 and the lifting frame 3 is the side facing away from the portal 25. Two rectangular through slots 27 are formed at the upper end of the square tube 22 to allow the lifting frame 3 to swing up and down. To increase the axial load of the shaft 12, a plane bearing 15 is installed between the top of the shaft 12 and the inner top surface of the cylinder 21. The swivel base 2 is equipped with a horizontal extension rod 24 and a door frame 25 to support the lifting platform 4 below to prevent the swivel base 2 from deflecting. The co-installed universal wheels 26 facilitate smooth tracking support during the rotation of the swivel base 2, improving the overall support stability and increasing the load-bearing capacity of the lifting platform 4.

[0036] The lifting platform 4 includes a vertical plate 41 arranged perpendicular to the ground. The lifting frame 3 is hinged to the vertical plate 41 through a hinge seat. A side of the vertical plate 41 is provided with at least two steps of stair treads 42, the structure of which is as follows: Figure 6 As shown. A work surface 43 extending horizontally toward the other side of the vertical plate 41 is fixed to the top surface of the vertical plate 41. A diagonal brace 44 is provided between the lower surface of the work surface 43 and the adjacent side surface of the vertical plate 41. A vertical pole 45 for mounting a first control switch 9 and a second control switch 10 is fixed to one side of the vertical plate 41. The lifting platform 4 has multiple steps 42 and a work surface 43 for standing during construction. Standing on the lifting platform 4 allows for a wide construction area. The second control switch 10 mounted on the platform 4 conveniently controls the second motor 7 to rotate the swivel base 2, which in turn drives the lifting platform 4. This allows for wide-scale construction without dismounting the lifting frame, improving efficiency in indoor ceiling construction. Standing on the platform 4, the first control switch 9 controls the first motor 5 to drive the adjustable eccentric wheel 6 to adjust the deflection angle of the lifting frame 3, thereby adjusting the height of the lifting platform 4. The height of the platform 4 can be adjusted at any time during construction to meet construction needs. The overall adjustment is flexible and adaptable to complex construction conditions.

[0037] Among them, the lifting frame 3 includes four rectangular rods 31 arranged in a rectangular shape and a retaining frame 32 connecting the four rectangular rods 31. The dimensions of the four rectangular rods 31 are exactly the same. A circular through hole 33 is opened from the side at the center of each of the four rectangular rods 31. The retaining frame 32 includes two cylindrical rods and a connecting end plate fixedly connected at both ends of the two cylindrical rods. One of the cylindrical rods passes through the circular through holes 33 of the two upper rectangular rods 31, and the other cylindrical rod passes through the circular through holes 33 of the two lower rectangular rods 31. The structure of the lifting frame 3 can ensure that when the swivel seat 2 installed on the base 1 is in a vertical state, the lifting platform 4 is always in a vertical state during the lifting process, ensuring that the construction personnel standing on the lifting platform 4 have a stable standing posture during the lifting process.

[0038] In order to increase the protection capability of the lifting platform 4, guardrails are installed on the sides of the stair treads 42 and the sides of the work standing surface 43.

[0039] To facilitate movement of the entire construction lift, two directional rollers 14 extending outward from the horizontal base plate 11 are fixed side by side. The lift 3 is rotated away from the directional rollers 14. One or two people lift the gantry 25 off the ground. With the two directional rollers 14 in contact with the ground, the entire construction lift can be moved manually by controlling the direction and speed. This method is quick and convenient for indoor construction.
