DETAILED DESCRIPTION

[0023] The following will be combined with the 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.

[0024] When implementing: Figure 1-4 As shown, an assembled construction platform for building construction includes: a base 100 and an electric push rod 200, the electric push rod 200 is fixedly connected to the top of the base 100, the top of the electric push rod 200 is fixedly connected to a fixed platform 400, and the inner wall of the fixed platform 400 is slidably connected to a mobile platform 410;

[0025] The adjusting mechanism 300 includes a slide rail 310 fixedly connected to the inner wall of the fixed platform 400, a bidirectional lead screw 312 is provided inside the slide rail 310, and the surface of the bidirectional lead screw 312 is threadedly connected to two connecting blocks 313, the inner wall of the mobile platform 410 is rotatably connected to the first transmission rod 321, the surface of the first transmission rod 321 is fixedly connected to the worm gear 320, the surface of the worm gear 320 is meshed with a worm 3201, the surface of the first transmission rod 321 is fixedly connected to two first groove wheels 322, the top of the mobile platform 410 is rotatably connected to two second groove wheels 323, the surface of the base 100 is rotatably connected to the second transmission rod 332, the surface of the second transmission rod 332 is fixedly connected to two third groove wheels 331, and the end of the second transmission rod 332 away from the slide rail 310 is fixedly connected to the spring 330.

[0026] like Figure 1 、 Figure 2 and Figure 3 As shown, a steel cable 340 is connected for transmission between the first sheave 322, the second sheave 323 and the third sheave 331, and a toolbox 500 is fixedly connected to the surface of the steel cable 340. One end of the bidirectional lead screw 312 is rotatably connected to the inner wall of the slide rail 310, and the other end of the bidirectional lead screw 312 passes through the slide rail 310 and is fixedly connected to the motor 311. Two mobile platforms 410 are slidably connected to the inner wall of the fixed platform 400, and the two mobile platforms 410 are located on opposite sides of the fixed platform 400. The cross-section formed by the combination of the fixed platform 400 and the mobile platform 410 is rectangular, four guide rods 210 are fixedly connected to the four corners of the base 100, and four universal wheels 600 are fixedly connected to the bottom end of the base 100.

[0027] In this embodiment, the steel cable 340 passes through the tool box 500 and is fixedly connected. When the steel cable 340 moves, it is necessary to adjust the angle to prevent it from contacting the bottom end of the mobile platform 410 and getting stuck. Because the mobile platform 410 is arranged inside the fixed platform 400, the outer shell volume of the fixed platform 400 is larger than the mobile platform 410, so when the slide rail 310 is fixed to the fixed platform 400, it is not fixed to the mobile platform 410, and the connecting block 313 can also work normally. The bottom end of the guide rod 210 is fixedly connected to the surface of the base 100, and the top end is fixedly connected to the bottom end of the mobile platform 410, and can be retracted and extended at the same time.

[0028] like Figure 2 、 Figure 3 and Figure 4As shown, the inner wall of the base 100 is slidably connected to a movable plate 110, the bottom end of the movable plate 110 is fixedly connected to four counterweight blocks 120, the bottom end of the counterweight block 120 is fixedly connected to a plurality of positioning blocks 121, the inner wall of the movable plate 110 is threadedly connected to a threaded rod 130, the top of the threaded rod 130 is fixedly connected to a first gear 131, the surface of the first gear 131 is meshed with a second gear 132, the end of the second gear 132 away from the first gear 131 is fixedly connected to a third transmission rod 133, and the end of the third transmission rod 133 away from the second gear 132 is fixedly connected to a handle 134.

[0029] In this embodiment, four grooves with the same area as the counterweight block 120 are opened at the bottom end of the base 100, so that the counterweight block 120 can pass normally without hindering the placement of the universal wheel 600, and the positioning block 121 is conical, and the bottom end of the threaded rod 130 is rotatably connected to the inner bottom wall of the base 100.

[0030] When the utility model is in use, the device is moved to the area to be constructed, and the third guide rod 210 and the first gear 131 and the second gear 132 are driven to rotate by turning the handle 134. The second gear 132 drives the threaded rod 130 to rotate, so that the movable plate 110 moves downward, and the positioning block 121 on the counterweight block 120 is driven into the ground, completing the overall fixation of the device. Then the staff enters the fixed platform 400 and starts the electric push rod 200. The electric push rod 200 pushes the fixed platform 400 to move upward under the guidance of the guide rod 210. When it reaches the predetermined position, the two-way lead screw 312 is rotated by starting the motor 311, driving the two connecting blocks 313 to move back and forth on the surface of the slide rail 310. At the same time, the two connecting blocks 313 drive the two movable platforms 410 to slide out from the inner wall of the fixed platform 400 to both sides to increase the working area. When the tool is transported, the worm 3201 is rotated clockwise, and the worm 3201 drives the turbine 320 to rotate, and the first groove wheel 322 rotates synchronously to reel in the steel cable 340, and the steel cable 340 drives the tool box 500 to move upward, and the spring 330 is tightened synchronously. When the tool box 500 reaches the top of the mobile platform 410, the tool is taken out, and then the worm 3201 is rotated counterclockwise to unfold the steel cable 340 on the surface of the first groove wheel 322. At this time, the spring 330 is relaxed, driving the second transmission rod 332 to drive the third groove wheel 331 to reel in the steel cable 340, so that the steel cable 340 drives the tool box 500 to move downward to complete the reset. The bidirectional lead screw 312 is in the form of two thread grooves with the same pitch and opposite rotation direction, and the two ends are connected by a transition curve. Through the rotation of the bidirectional lead screw 312, the side of the spiral groove pushes the slider placed in the spiral groove to perform axial reciprocating motion.

[0031] When the lead angle of worm 3201 is less than the equivalent friction angle between the meshing gear teeth, the mechanism exhibits self-locking properties, achieving reverse self-locking. This means that only worm 3201 can drive worm wheel 320, not worm wheel 320. For example, the reverse self-locking property of the self-locking worm 3201 mechanism used in heavy machinery can provide safety protection. "When the worm wheel 320 is the active component and the lead angle of the worm-wheel mechanism is less than the friction angle, the mechanism will self-lock." / Reference: China New Technologies and New Products, 2016, Issue 14, Page 43.

[0032] It should be noted that the electric push rod 200, motor 311, spring 330, worm gear 320 and worm 3201 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the electric push rod 200 and motor 311 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0033] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
