[0030] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0031] See also Figure 1-2This utility model provides a technical solution: a support device for building construction. It includes a base 1, with support frames 4 slidably inserted into both sides of the base 1. Each support frame 4 includes a support plate and three connecting plates fixedly mounted on the support plate.

[0032] The upper surface of the base 1 has a groove 22. Two first sliding grooves 7 are symmetrically formed on the bottom surface of the groove 22, and the two first sliding grooves 7 are equipped with a stabilizing structure inside.

[0033] The stabilizing structure includes a third lead screw 19, which is rotatably mounted inside two first slide grooves 7. The interiors of both first slide grooves 7 are slidably connected to connecting plates at the middle positions on the corresponding support frames 4. The outer surfaces of both sides of the third lead screw 19 are threadedly connected to the connecting plates at the middle positions on the corresponding support frames 4.

[0034] Furthermore, a first motor 2 is fixedly installed on the bottom surface of the groove 22, and a first lead screw 3 is fixedly installed on the output shaft of the first motor 2.

[0035] A fixing plate 12 is fixedly installed on the bottom surface of the groove 22 on the side away from the first motor 2. The end of the first lead screw 3 away from the first motor 2 is rotatably connected to the fixing plate 12; a first slider 9 is threadedly connected to the outer surface of the first lead screw 3. The first slider 9 is slidably disposed in the groove 22.

[0036] Furthermore, a rack 17 is fixedly mounted on the side of the first slider 9 near the first motor 2. A gear 18 is fixedly sleeved on the outer surface of the third lead screw 19 at the position corresponding to the rack 17, and the gear 18 meshes with the rack 17. The first slider 9 moves the rack 17, and the meshing of the rack 17 with the gear 18 causes the third lead screw 19 to rotate. The third lead screw 19 causes the two support frames 4 to move in opposite directions along the axis of the third lead screw 19, so that the two support frames 4 move out of the base 1.

[0037] The support frame 4 is equipped with a support device; a lifting component is installed inside the groove 22, and a support platform 15 is installed on the lifting component. The lifting component is driven and connected to the third lead screw 19.

[0038] Furthermore, the support device includes hydraulic cylinders 5; a hydraulic cylinder 5 is fixed to the upper surface of both ends of each support frame 4. The telescopic ends of the four hydraulic cylinders 5 extend to the lower surface of the corresponding support frame 4, and a pad 6 is fixedly installed on the telescopic ends of the four hydraulic cylinders 5. When the hydraulic cylinders 5 are activated, the hydraulic rods of the hydraulic cylinders 5 extend, causing the pad 6 to abut against the ground to accommodate the height increase of the support platform 15, thereby improving the overall stability of the device.

[0039] Furthermore, the lifting assembly includes two second connecting plates 11. The two second connecting plates 11 are rotatably mounted on both sides of the groove 22, and the ends of the two second connecting plates 11 away from the base 1 are disposed on the bottom side of the support platform 15;

[0040] First connecting plates 10 are rotatably mounted on both sides of the first slider 9, and the ends of the two first connecting plates 10 away from the first slider 9 are rotatably mounted on the bottom surface of the support platform 15. The two first connecting plates 10 are respectively rotatably connected to the second connecting plates 11 on the same side.

[0041] Furthermore, the bottom surface of the support platform 15 has a second groove 23. Both sides of the interior of the second groove 23 have second sliding grooves 20. Second sliders 21 are slidably installed inside each of the two second sliding grooves 20. The opposite ends of the two second sliders 21 are rotatably connected to corresponding second connecting plates 11. When this device is not in use, the first connecting plate 10 and the second connecting plate 11 are folded and stored inside the first and second grooves. When needed, the first motor 2 is started, and the output shaft of the first motor 2 rotates the first lead screw 3. The first lead screw 3 causes the first slider 9 to move along the axis of the first lead screw 3, and the first slider 9 causes the first connecting plate 10 and the second connecting plate 11 to move. The end of the second connecting plate 11 away from the base 1 slides on the bottom surface of the support platform 15 via the second slider 21, thereby raising the support platform 15 to support the object.

[0042] The support platform 15 is provided with an extension device.

[0043] Furthermore, the extension device includes a second motor 8, which is fixedly mounted on the side of the support platform 15; the support platform 15 has two connecting holes 16 on the side near the first motor 2. A second lead screw 13 is fixedly mounted on the output shaft of the second motor 8, and the second lead screw 13 passes through the interior of the two connecting holes 16 and is rotatably connected to the support platform 15.

[0044] Both sides of the support platform 15 are provided with third sliding grooves 24, which communicate with the corresponding connecting holes 16. Support plates 14 are slidably installed inside each of the two third sliding grooves 24. Connecting blocks 25 are fixedly installed on each support plate 14 at the positions corresponding to the connecting holes 16. Both connecting blocks 25 are threadedly connected to the outer surface of the second lead screw 13. When the second motor 8 is started, it rotates the second lead screw 13, causing the two support plates 14 to move in opposite directions along the axis of the second lead screw 13, thereby increasing the contact area between the support platform 15 and the object.

[0045] Working principle: In use, the device is moved to the construction site by the casters on the bottom of the base 1. When it is necessary to support an object, the first motor 2 is started. The output shaft of the first motor 2 causes the first lead screw 3 to rotate. The rotation of the first lead screw 3 causes the first slider 9 to move along the axis of the first lead screw 3. The first slider 9 causes the first connecting plate 10 and the second connecting plate 11 to move. The end of the second connecting plate 11 away from the base 1 slides on the bottom surface of the support platform 15 through the second slider 21, thereby raising the support platform 15 to facilitate support of the object.

[0046] At the same time, the first slider 9 causes the rack 17 to move, and the rack 17 meshes with the gear 18 to rotate the third lead screw 19. The third lead screw 19 causes the two support frames 4 to move in opposite directions along the axis of the third lead screw 19, so that the two support frames 4 are moved out of the base 1.

[0047] Once the support platform 15 has been raised to the required height, the hydraulic cylinder 5 is activated. The hydraulic rod of the hydraulic cylinder 5 extends, causing the pad 6 to contact the ground, in order to accommodate the increased height of the support platform 15 and thus improve the overall stability of the device.

[0048] The second motor 8 starts, causing the second lead screw 13 to rotate. The second lead screw 13 causes the two side support plates 14 to move in opposite directions along the axis of the second lead screw 13, so as to increase the contact area between the support platform 15 and the object.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
