[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] See Figure 1An elevator shaft construction platform includes: a hoist 1 installed at the top of the elevator shaft, with a steel wire rope 2 wound on the hoist 1, a portion of which extends into the elevator shaft; a guide rail 4 installed on the inner wall of the elevator shaft, extending along the height direction of the elevator shaft; a movable platform 3 fixed to the bottom of the steel wire rope 2, with an upper guide shoe 35 at the end of the movable platform 3 corresponding to the guide rail 4, the upper guide shoe 35 being engaged with the guide rail 4; and a mechanical brake installed on the movable platform 3 and corresponding to the steel wire rope 2.

[0028] In a preferred embodiment of this invention, the hoist 1 is installed at the top of the elevator shaft. The length of the wire rope 2 on the hoist 1 is determined according to the height of the elevator shaft. When assembling the wire rope 2 and the moving platform 3, the wire rope 2 is first lowered to the bottom of the elevator shaft, and then the moving platform 3 is assembled at the bottom of the elevator shaft. After the moving platform 3 is assembled, the wire rope 2 and the moving platform 3 are assembled together. Then, the upper guide shoe 35 of the moving platform 3 is engaged with the guide rail 4. The guide rail 4 can prevent the moving platform 3 from shaking when moving up and down. Then, a mechanical brake is installed on the moving platform 3, which is set corresponding to the wire rope 2. During construction, the construction personnel stand on the moving platform 3. When it is necessary to move to other heights, the hoist is started, so that the hoist lowers or raises the moving platform 3 to the corresponding height to facilitate the construction personnel to carry out the construction.

[0029] Furthermore, a support column is provided on the top of the mobile platform 3, and a protective canopy is provided on the top of the support column. The protective canopy covers the mobile platform 3, and an opening is formed in the protective canopy corresponding to the position of the steel wire rope 2. The steel wire rope 2 passes through the opening to connect to the mobile platform 3. This protective canopy can protect against falling objects from above, thereby increasing the safety of construction personnel.

[0030] Furthermore, a lower beam 31 is fixedly installed at the bottom of the mobile platform 3, and a lower guide shoe 34 is installed on the side of the lower beam 31 corresponding to the guide rail 4. The lower guide shoe 34 is snapped into the guide rail 4. Preferably, there are two lower beams 31, which are arranged opposite each other on both sides of the mobile platform 3. A straight beam 33 is arranged between the two lower beams 31, and the straight beam 33 is connected to the lower beam 31 by an M12×25 bolt assembly.

[0031] Furthermore, to facilitate the quick assembly and disassembly of the mobile platform 3 and to enhance its rigidity, the mobile platform 3 is equipped with a matrix reinforcement structure. This matrix reinforcement structure consists of four 1170mm short ribs spliced ​​together by M12×35 bolts into two groups of 1700-1900mm units, which are then fixed to both sides of the mobile platform 3.

[0032] Furthermore, a number of diagonal braces 32 are provided between the lower beam 31 and the mobile platform 3.

[0033] Furthermore, the mobile platform 3 and the lower beam 31 are fixedly connected by bolts.

[0034] Furthermore, a safety barrier is provided on the top of the mobile platform 3, and the safety barrier is provided along the edge of the mobile platform 3. Preferably, a retractable handrail is installed on the top of the safety barrier. The handrail consists of a telescopic sleeve and a telescopic rod sliding inside the telescopic sleeve. Adjustment holes are provided at intervals on the telescopic sleeve and the telescopic rod. The handrail is fixed according to its length by inserting bolts into the adjustment holes at corresponding positions on the telescopic sleeve and the telescopic rod.

[0035] Furthermore, two crossbeams 12 are arranged opposite each other at the top of the elevator shaft, and a crossbeam 11 is arranged between the two load-bearing beams. The hoist 1 is arranged on the crossbeam 11. Preferably, the crossbeam 12 is arranged at the top of the elevator shaft and opposite each other on both sides of the elevator shaft. The crossbeam 11 with a circular tube is arranged on the load-bearing beam, and the hoist 1 is arranged below the crossbeam 11.

[0036] Furthermore, a mounting groove is provided at the top of the crossbeam 12, and the crossbeam 11 is disposed within the mounting groove. In this embodiment, a channel steel is welded to the top of the crossbeam 12 to form a mounting groove for placing the crossbeam 11.

[0037] Furthermore, the hoist 1 is fixed to the crossbeam 11 by welding.

[0038] Furthermore, the size of the mobile platform 3 is determined according to the on-site construction requirements.

[0039] The following describes the usage process of the elevator shaft construction platform of the present invention.

[0040] The hoist 1 is installed at the top of the elevator shaft. The length of the wire rope 2 on the hoist 1 is determined according to the height of the elevator shaft. When assembling the wire rope 2 and the moving platform 3, the wire rope 2 is first lowered to the bottom of the elevator shaft. Then, the moving platform 3 is assembled at the bottom of the elevator shaft. After the moving platform 3 is assembled, the wire rope 2 and the moving platform 3 are assembled together. Then, the upper guide shoe 35 of the moving platform 3 is clamped to the guide rail 4. The guide rail 4 can prevent the moving platform 3 from shaking when moving up and down. Then, a mechanical brake is installed on the moving platform 3, which is set corresponding to the wire rope 2. During construction, the construction personnel stand on the moving platform 3. When it is necessary to move to other heights, the hoist is started, so that the hoist lowers or raises the moving platform 3 to the corresponding height to facilitate the construction personnel to carry out the construction.
