DETAILED DESCRIPTION

[0036] The following description of the embodiments will help the public better understand the present invention, but the specific embodiments given by the applicant cannot and should not be regarded as limitations on the technical solutions of the present invention. Any changes to the definitions of components or technical features and / or formal but not substantial changes to the overall structure should be regarded as the scope of protection defined by the technical solutions of the present invention.

[0037] See also Figure 1 to Figure 2 As shown, the technical solution of the present invention is as follows:

[0038] An electric self-climbing indoor construction elevator is arranged in the elevator shaft of a building, comprising an elevator car 12 and a load-bearing connecting beam 1 located above the elevator car 12. Slide rails 9 arranged along the height direction of the elevator shaft are fixed on both side walls of the elevator shaft. The slide rails 9 are fixed to the two side walls of the elevator shaft by high-strength bolts 3. The height of the slide rails 9 is determined according to the construction requirements. Both ends of the load-bearing connecting beam 1 are slidably mounted on the slide rails 9 up and down. Both ends of the load-bearing connecting beam 1 are detachably connected to the two side walls of the elevator shaft. A traction machine 2 is fixed on the upper surface of the middle part of the load-bearing connecting beam 1. The traction machine 2 is connected to the elevator car 12 by a connecting rope 14. The connection One end of the rope 14 is wound and fixed on the traction machine 2, and the other end of the connecting rope 14 is fixed on the lower bottom surface of the load-bearing connecting beam 1. A movable pulley 15 is arranged on the connecting rope 14, and a hook 16 is connected to the movable pulley 15. A fixing ring 17 is fixedly welded on the top of the elevator car 12, and the hook 16 is connected to the fixing ring 17. The elevator car 12 is raised and lowered in the elevator shaft under the drive of the traction machine 2; electric climbers are fixed at the same height on both side walls above the load-bearing connecting beam 1 and at the top of the elevator shaft, and the two electric climbers are connected to the load-bearing connecting beam 1. The load-bearing connecting beam 1 is raised and lowered in the elevator shaft under the synchronous drive of the two electric climbers.

[0039] The load-bearing connecting beam 1 includes a first I-beam and a second I-beam, which are arranged in parallel and at a certain distance. The above-mentioned structural arrangement is conducive to installing a pulley 11 on the load-bearing connecting beam 1, thereby enabling the load-bearing connecting beam 1 and the slide rail 9 to slide up and down.

[0040] A connecting plate 18 is welded in the middle of the upper surface of the first I-beam and the second I-beam. The connecting plate 18 is a steel plate. The connecting plate 18 connects the first I-beam and the second I-beam together, and the traction machine 2 and the connecting plate 18 are bolted. The above-mentioned structural arrangement is not only conducive to increasing the load of the load-bearing connecting beam 1, avoiding bending and deformation of the load-bearing connecting beam 1 during use, and ensuring safe use, but also can centrally and firmly install the traction machine 2 on the load-bearing connecting beam 1, preventing the traction machine 2 from tilting and deviating due to the influence of the elevator car 12 after the connection between the traction machine 2 and the elevator car 12.

[0041] A fixing plate 19 is welded to the same end of the first I-beam and the second I-beam. The fixing plate 19 is a steel plate. The two fixing plates 19 and the two side walls of the elevator shaft are connected by high-strength bolts 3. The above-mentioned structural setting can solve the problem of reserving holes in the shear wall part on the side wall 13 of the elevator shaft, ensure the quality and safety of the overall building structure, and reduce the damaged area of ​​the shear wall part.

[0042] The slide rails 9 on both sides are placed between the two ends of the first I-beam and the second I-beam, and pulleys 11 slidably connected to the slide rails 9 are fixedly connected to the upper surfaces of the two ends of the first I-beam and the second I-beam; the above-mentioned structural setting is conducive to the load-bearing connecting beam 1 sliding up and down along the slide rails 9, reducing the friction resistance when the load-bearing connecting beam 1 is lifted upward.

[0043] The electric climbing machine includes a conical rotor brake motor 7, a wire rope 8 and a wire rope drum. An anchor plate body 20 is fixed on the side wall of the elevator shaft by high-strength bolts 3. The anchor plate body 20 is a steel plate. The conical rotor brake motor 7 is fixed on the anchor plate body 20. The wire rope drum is connected to the conical rotor brake motor 7. One end of the wire rope 8 is wound and fixed on the wire rope drum. A hook 5 is connected to the other end of the wire rope 8. The wire rope 8 is connected to the load-bearing connecting beam 1 through the hook 5.

[0044] A lifting ring plate 21 is welded to the load-bearing connecting beam 1 and both sides of the traction machine 2. The lifting ring plate 21 is a steel plate, and a lifting ring 6 connected to the hook 5 of the electric climber is welded to the lifting ring plate 21. The above-mentioned structural arrangement can enable the traction machine 2 and the load-bearing connecting beam 1 to move synchronously during the lifting process, preventing the load-bearing connecting beam 1 from getting stuck during the rising process along the slide rail 9, while ensuring the stability of the connection between the load-bearing connecting beam 1 and the electric climber.

[0045] A first guide rope pulley plate 22 is welded on the load-bearing connecting beam 1 and on both sides of the traction machine 2, a first guide rope pulley 4 is fixed on the first guide rope pulley plate 22, a second guide rope pulley 23 is fixed on the anchor plate 20, and the hook 5 on the wire rope 8 is connected to the load-bearing connecting beam 1 via the first guide rope pulley 4, the second guide rope pulley 23 in sequence; the above-mentioned structural arrangement can ensure that the wire rope 8 is more stable during the lifting process to prevent shaking.

[0046] The two conical rotor brake motors 7 are electrically connected to a control switch 10 for controlling the synchronous retraction and extension of the wire rope 8; the above-mentioned structural arrangement controls the retraction and extension of the wire rope 8 through the control switch 10 to achieve the purpose of lifting the load-bearing connecting beam 1, and the two climbing machines can achieve one-button synchronous lifting and lowering through the connection and synchronous control switch 10.
