[0035] See also Figure 1-9 .

[0036] The present invention provides a technical solution for an elevator shaft construction platform: an elevator shaft construction platform, which is applied to a construction work platform in the elevator shaft, comprising a support table top 1 composed of a base 101 and a support plate 102, and also comprising: a construction platform 2 composed of a load-bearing plate 201 and a threaded ring 202 arranged at the center of the load-bearing plate 201, for supporting construction personnel in the elevator shaft for construction work; a driving component 3 arranged at the upper end of the support plate 102, for driving the construction platform 2 to move up and down in the elevator shaft; and a supporting component 4 arranged inside the base 101, for contacting the inner wall of the elevator shaft to fix the support table top 1.

[0037] By setting up a base 101, a support plate 102, a construction platform 2, a driving assembly 3 and a supporting assembly 4, the driving assembly 3 can drive the construction platform 2 to move freely above the supporting plate 102. At the same time, the construction platform 2 can be quickly transferred through the retractable supporting assembly 4, which saves a lot of work hours and allows continuous construction on higher floors without pre-installing a crane.

[0038] In one embodiment, an opening matched with the threaded ring 202 is provided at the center of the load-bearing plate 201, the threaded ring 202 is fixedly arranged at the center of the load-bearing plate 201, a plurality of circular support bars 2021 are fixedly arranged on the outer wall of the threaded ring 202, the other end of the support bar 2021 is fixedly arranged on a side surface of the load-bearing plate 201, and a plurality of transfer wheels 103 are arranged on the bottom surface of the base 101.

[0039] With this design, the transfer wheel 103 is set so that the support table 1 and the construction platform 2 can be quickly transferred and transported to other elevator shaft construction layers without complicated assembly. The support bar 2021 is set to evenly distribute the load-bearing of the entire load-bearing plate 201 and reinforce the threaded ring 202.

[0040] In one embodiment, the driving assembly 3 includes a motor 301 and a driving gear 302 arranged at the output end of the motor 301, a driven gear 303 meshing with the driving gear 302 is arranged on one side of the driving gear 302, and the driving gear 302 and the driven gear 303 are both rotatably arranged on one side of the support plate 102, the motor 301 is fixedly connected to the support plate 102 through an L-shaped angle steel, a threaded shaft 304 is fixedly arranged at the center of one side of the driven gear 303, one end of the threaded shaft 304 passes through the threaded ring 202 and is threadedly connected thereto, a plurality of sliding shafts 305 are fixedly arranged on one side of the support plate 102, and a plurality of movable holes 203 matching the sliding shafts 305 are opened on the load-bearing plate 201.

[0041] With this design, when the height of the load-bearing plate 201 needs to be adjusted, the motor 301 is started by the control key, and the output shaft of the motor 301 will drive the driving gear 302 to rotate, and the driving gear 302 rotates to drive the driven gear 303 to rotate, and then drives the threaded shaft 304 to rotate. When the threaded shaft 304 rotates, the threaded ring 202 adapted thereto will start to move upward or downward, and at the same time drive the load-bearing plate 201 to start moving synchronously, and the moving hole 203 on the load-bearing plate 201 will also slide on the sliding shaft 305.

[0042] In one embodiment, the support assembly 4 includes a rotating disk 401 rotatably arranged on the inner side wall of the base 101 and a plurality of movable plates 402 slidably arranged inside the base 101. The base 101 is hollow inside, and the side wall of the base 101 is provided with a recess matched with the movable plate 402. A driving bar 403 meshing with the rotating disk 401 is fixedly arranged at one end of the movable plate 402. The outer side wall of the rotating disk 401 is provided with teeth. The driving bar 403 and the opposite side of the rotating disk 401 are also provided with matching teeth. At the same time, the driving bars 403 are mirror-imaged in pairs, and the height of a single driving bar 403 is only half of the rotating disk 401. A sliding bar 4031 slidably connected to the inner side wall of the base 101 is fixedly arranged on one side of the driving bar 403. The sliding bar 4031 is provided to enable the driving bar 403 to move. The base 101 can slide on the corresponding inner wall of the base 101, and a rotating handle 404 is rotatably provided at the bottom end of the inner wall of the base 101, which passes through the upper side of the base 101 and the support plate 102. A transmission belt 405 is provided between the rotating handle 404 and the rotating disk 401, and a transmission disk 1 4051 fixedly connected to the rotating handle 404 and a transmission disk 2 4052 fixedly connected to the rotating disk 401 are respectively provided at both ends of the transmission belt 405. The radius of the transmission disk 1 4051 and the transmission disk 2 4052 are greatly different, and the radius of the transmission disk 2 4052 is larger than that of the transmission disk 1 4051. This arrangement is to save more effort when rotating the rotating disk 401 by rotating the handle 404. A latch 406 is slidably provided on the rotating handle 404, and a limiting hole 1021 adapted to the latch 406 is provided on the upper end surface of the support plate 102.

[0043] With this design, the support table 1 and the construction platform 2 are pushed to one side of the elevator shaft by the transfer wheel 103. At this time, by turning the rotating handle 404, the rotation of the rotating handle 404 will drive the transmission disk 1 4051 to rotate, thereby driving the transmission disk 2 4052 to rotate through the transmission belt 405, and then driving the rotating disk 401 to rotate. The rotation of the rotating disk 401 will drive the driving bar 403 engaged with it to start moving, and the driving bar 403 will drive the moving plate 402 at one end to slide. When the moving plate 402 is completely moved out of the base 101, it will contact the preset side wall connecting piles in the elevator shaft. The setting of the connecting piles is the existing technology and will not be elaborated here. At this time, the pin 406 on the rotating handle 404 is inserted into the limiting hole 1021 on the support plate 102 to complete the fixing of the rotating handle 404.

[0044] In one embodiment, a special-shaped column 3041 is fixedly provided at one end of the threaded shaft 304, and a special-shaped groove 3042 adapted to the special-shaped column 3041 is provided at the other end of the threaded shaft 304; a special-shaped column 3051 is fixedly provided at one end of the sliding shaft 305, and a special-shaped groove 3052 adapted to the special-shaped column 3051 is provided at the other end of the sliding shaft 305.

[0045] With this design, two or more threaded shafts 304 and sliding shafts 305 can be correspondingly spliced ​​together through special-shaped column 1 3041, special-shaped groove 1 3042, special-shaped column 2 3051 and special-shaped groove 2 3052. This arrangement is so that when continuous upper and lower floor construction is required in the elevator shaft, there is no need to move the supporting table 1 and the construction table 2, and the load-bearing plate 201 can be moved to a higher position directly by splicing the threaded shaft 304 and the sliding shaft 305.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
