DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 7As shown, a lifting platform for house construction includes a base 1, a lifting rod 2 and a supporting platform 3, wherein the bottom of the base 1 is provided with a moving wheel, the lifting rod 2 is fixedly connected to the middle of the top of the base 1, and the top of the lifting rod 2 is fixedly connected to the supporting platform 3 through a fixing frame 201, and movable side panels 4 are provided on both sides of the supporting platform 3, and the opposite sides of the two groups of side panels 4 are fixedly connected to multiple groups of support plates 401 arranged alternately with each other, and the multiple groups of support plates 401 are respectively slidably connected to the two sides of the fixing frame 201, and the opposite sides of the side panels 4 are fixedly connected to protective plates 402, which slide on both sides of the supporting platform 3, and at the same time, two groups of driving wheels are rotatably connected inside the fixing frame 201. The two drive shafts 5 are fixedly connected with transmission gears 501 on the outer walls of the two drive shafts 5. One of the multiple support plates 401 fixedly connected to the side walls of the two side plates 4 is fixedly connected with a rack 502 on the bottom. The two transmission gears 501 are respectively meshed with the two racks 502. By starting the two drive motors (not shown in the figure), the two drive shafts 5 are driven to rotate. The two drive shafts 5 drive the two transmission gears 501 to mesh with the two racks 502, thereby pushing the support plates 401 on the two racks 502 to slide on the fixed frame 201. The two support plates 401 respectively drive the two side plates 4 to slide on both sides of the support platform 3 to stretch and unfold, so as to increase the support area of ​​the support platform 3.

[0026] like Figure 1 and Figure 4 As shown, cavities 301 are opened on both sides of the above-mentioned support platform 3, and the protective plates 402 fixedly connected to the side walls of the two groups of side panels 4 slide inside the two groups of cavities 301 respectively, and the two groups of protective plates 402 in each group of cavities 301 slide against each other. On the one hand, the storage of the protective plates 402 can be hidden, and on the other hand, the two groups of protective plates 402 are limited by each other to avoid shaking after unfolding.

[0027] like Figure 1 and Figure 7As shown, the two side walls of the support platform 3 are fixedly connected with fixed rods 6, and a rotating rod 601 is rotatably connected between the two groups of fixed rods 6. Multiple groups of pull ropes 602 are fixedly wound around the outer wall of the rotating rod 601. The ends of the multiple groups of pull ropes 602 away from the rotating rod 601 are respectively fixedly connected to the two ends of the two groups of side panels 4. When the two groups of side panels 4 move on both sides of the support platform 3 to extend, the pull ropes 602 are pulled to wind around the outer wall of the rotating rod 601. When the side panels 4 move to the extreme position, the pull ropes 602 are also wound to the longest length at this time, so that the pull ropes 602 provide a certain pulling force on the tops of the two groups of side panels 4. The pulling force provides a certain upward pulling force to the support plate 401 when a person stands on the support plate 401, so as to improve the stability and safety of the construction of the person standing on the support plate 401. At the same time, a reset coil spring 603 is fixedly connected to the side wall of the fixed rod 6, and one end of the reset coil spring 603 is fixedly connected to the outer wall of the rotating rod 601. Therefore, when the side plate 4 is used and reset and stored, the reset coil spring 603 can drive the rotating rod 601 to rotate and wind up the pull rope 602, so as to prevent the pull rope 602 from loosely dragging on the support platform 3. At the same time, the pull rope 602 can be made of nylon rope or wire rope.

[0028] like Figure 1 and Figure 6 As shown, multiple groups of limit rods 403 are fixedly connected to the opposite sides of the two groups of side panels 4 mentioned above, and the multiple groups of limit rods 403 are respectively slidably connected to the two side walls of the fixing frame 201. Two groups of limit blocks 404 are fixedly connected inside the fixing frame 201, and the multiple groups of limit rods 403 are respectively slidably connected to the side walls of the two groups of limit blocks 404. When the two groups of side panels 4 slide, they drive the multiple groups of limit rods 403 to slide synchronously on both sides of the fixing frame 201. The sliding extension of the side panels 4 is supported by the limit rods 403, so as to improve the stability of the support after the side panels 4 are extended. At the same time, double-point limit is formed by the setting of the limit blocks 404 and the sliding of the limit rods 403 on the side walls of the fixing frame 201, so as to improve the support strength of the limit rods 403.

[0029] like Figure 1 As shown, a telescopic rod 202 is fixedly connected to the top of the base 1, and the top of the telescopic rod 202 is fixedly connected to the bottom of the fixed frame 201. The telescopic rod 202 follows the lifting rod 2 to move up and down to adjust the height of the support platform 3, thereby improving the stability of the support platform 3.

[0030] The working principle of the utility model is as follows: when the user uses it, he climbs up the support platform 3 by climbing a ladder or other means, and then starts the lifting rod 2 to drive the support platform 3 to move upward to rise. After the rise is completed, when it is necessary to increase the support surface of the support platform 3, the two sets of drive shafts 5 are started to rotate, and the two sets of drive shafts 5 drive the two sets of transmission gears 501 to rotate. The two sets of transmission gears 501 are meshed with the racks 502 at the bottom of the two sets of support plates 401, thereby pushing the two sets of support plates 401 to drive the two sets of side plates 4 to slide and open on both sides of the support platform 3, and the two sets of side plates 4 move. At the same time, the protective plates 402 at both ends are driven to slide and extend on both sides of the support platform 3. At this time, multiple groups of support plates 401 form a foot support surface, and two groups of side plates 4 form protective surfaces at both ends of the support platform 3. The protective plates 402 on both sides of the side plates 4 are extensions of the protective surfaces on both sides of the support platform 3 to form side protection for the support plates 401, thereby improving the adjustment of the support area range of the support platform 3 while maintaining the protective effect of the support platform 3 after extension, thereby reducing the number of times that the support platform 3 is repeatedly moved by humans, and increasing the working range of humans on the support platform 3.

[0031] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
