DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] First, according to Figure 1-Figure 3 As shown, the embodiment of the present application proposes an adjustable lifting construction platform for house construction engineering, including two bases 1 arranged opposite to each other and a workbench 2 above the base 1, the upper end of the base 1 is detachably provided with a guide column assembly vertically upward, the number of the guide column assemblies is one or more groups, when the number of the guide column assemblies is multiple groups, the upper end of the lower guide column assembly and the lower end of the upper guide column assembly in two adjacent groups of the guide column assemblies are detachably connected; both ends of the workbench 2 are provided with guide holes that slide with the guide column assemblies, The upper end of the guide column assembly farthest from the base 1 is detachably connected to a connecting frame, the connecting frame is provided with a pulley block 10, the base 1 is provided with a winch 9, and the tension rope 11 of the winch 9 passes through the pulley block 10 to connect to the workbench 2; before use, according to the on-site building height, if multiple sets of guide column assemblies are used, they are assembled upward in sequence, and the connecting frame is installed on the upper end of the uppermost guide column assembly. The connecting frame is used to install and support the pulley block 10, and the tension rope 11 of the winch 9 passes through the pulley block 10 to achieve the effect of vertically lifting the workbench 2 below.

[0025] It should be noted that the work platform 2 is lifted by the pulley block 10 via the tension rope 11 of the winch 9, and the work platform 2 slides relative to the guide column assembly, ensuring stability throughout the entire lifting process. By providing at least one set of guide column assemblies, different numbers of guide column assemblies can be flexibly installed in sequence according to the actual building height at the construction site, ensuring flexible adjustment of the lifting height and enhancing the universal applicability of the entire device.

[0026] like Figure 5 As shown, both bases 1 are equipped with a winch 9, and the two winches 9 work synchronously to ensure that the workbench 2 can achieve a smooth lifting effect.

[0027] Specifically, such as Figure 3As shown, the guide column assembly includes two vertical and oppositely arranged columns 3, and multiple groups of reinforcing ribs 14 are arranged between the two columns 3. A group of the reinforcing ribs 14 includes two connecting rods cross-arranged between the two columns 3; the columns 3 slide in cooperation with the inner wall of the guide hole, that is, the guide column assembly is assembled through the combination of the reinforcing ribs 14 and the columns 3, which can greatly improve the connection strength and support strength of the entire device, and ensure that the entire device can stably realize the guiding function of the workbench 2. When there are heavy objects or operators on the upper end of the workbench 2, the horizontal force applied to the workbench 2 is applied to the columns 3. The two columns 3 and the reinforcing ribs 14 cross-arranged in the middle can achieve stable lateral pressure resistance and sufficient support, and ensure the stability of the entire device when in use.

[0028] In order to further improve the stability of the workbench 2 during the lifting process, the above-mentioned column 3 is provided with a slide groove 15 along the length direction, and the inner wall of the above-mentioned guide hole is provided with a slider 16 that slides with the above-mentioned slide groove 15. That is to say, the contours of the above-mentioned slide groove 15 and the slider 16 match each other, and the inner wall of the slide groove 15 and the outer wall of the slider 16 are both smoothly set. The relative sliding can ensure that the workbench 2 will not shake or deflect when it is lifted and lowered along the guide column assembly, thereby ensuring safety.

[0029] Regarding the specific structure of the above-mentioned connecting frame, Figure 4 As shown, the connecting frame includes a frame body 4, a plug block 7 is provided at the lower end of the frame body 4, and a slot 8 is provided at the upper end of the guide column assembly farthest from the base 1 for plugging with the plug block 7. The pulley group 10 is provided on the frame body 4. Specifically, the pulley group 10 can be set to multiple fixed pulleys at different heights. The tension rope 11 of the winch 9 extends downward through the fixed pulley to the position of the workbench 2 and is connected to the workbench 2. In order to facilitate fixed connection, a binding ring 13 for connecting the tension rope 11 of the winch 9 is provided at the upper end of the workbench 2, which is convenient for tying the tension rope 11 to the binding ring 13, facilitating installation and operation, and improving efficiency.

[0030] Moreover, when there are multiple groups of guide column assemblies, the lower ends of the higher-positioned guide column assemblies are also provided with insert blocks 7, which can enable multiple groups of guide column assemblies to be gradually accumulated and installed upward, so that the entire device has a sufficient lifting height.

[0031] In order to further improve the stability of the entire device, a screw hole is provided at the upper end of the above-mentioned frame 4, and a screw rod 5 is threaded in the above-mentioned screw hole. A top plate 6 for abutting the top of the wall is provided at the end of the above-mentioned screw 5 away from the above-mentioned screw hole. During the installation process, the above-mentioned screw 5 is rotated to make the above-mentioned top plate 6 stably abut the top of the wall, ensuring that the entire device is subjected to a top-down abutment force, ensuring that multiple groups of guide column assemblies do not fall off or shake, and ensuring that the connecting frame and the topmost guide column assembly do not fall off or shake, thereby improving working stability, and the upper end of the above-mentioned top plate 6 can be provided with an anti-slip layer 17, which can specifically be a rubber pad with a rough surface. By abutting against the top of the wall, the friction coefficient is increased, thereby further improving stability.

[0032] Moreover, connecting plates 18 are provided on both sides of the frame 4. The connecting plates 18 are provided with mounting holes for inserting screws and fixing the connecting plates 18 to the wall. The connecting plates 18 are connected to the wall or the column 3 and other positions by bolts and screws to ensure that the entire device will not tip over, thereby greatly improving the safety of the device.

[0033] In order to facilitate the movement of the entire device at different working positions and improve work efficiency, a brake wheel 12 is provided at the lower end of the base 1.

[0034] In summary, the utility model proposes an adjustable lifting construction platform for house construction projects, comprising two relatively arranged bases 1 and a workbench 2 above the bases 1, the upper end of the base 1 is detachably provided with a guide column assembly vertically upward, and the number of the guide column assemblies is one or more groups. When the number of the guide column assemblies is multiple groups, the upper end of the lower guide column assembly and the lower end of the upper guide column assembly in two adjacent groups of the guide column assemblies are detachably connected; both ends of the workbench 2 are provided with guide holes that slide with the guide column assemblies, and the upper end of the guide column assembly farthest from the base 1 is detachably connected with a connecting frame, and the connecting frame is A pulley block 10 is provided, and the base 1 is provided with a winch 9. The tension rope 11 of the winch 9 passes through the pulley block 10 to connect to the workbench 2. The tension rope 11 of the winch 9 is used to lift the workbench 2 under the action of the pulley block 10, and the workbench 2 slides relatively to the guide column assembly to ensure the stability of the entire lifting process; by providing at least one group of guide column assemblies, different numbers of guide column assemblies can be flexibly used to be installed upward in sequence according to the actual building height of the construction site, ensuring flexible adjustment of the lifting height and improving the universal applicability of the entire device. Moreover, the structure of the entire device is relatively simple, convenient to process and install, with more fixing points and better safety.
