Description

Technical Field

[0001] This invention relates to the field of auxiliary support technology, specifically an auxiliary support device for building construction. Background Technology

[0002] Building construction includes foundation construction, main structure construction, roofing construction, and decoration construction. The place where construction work is carried out is called the "construction site" or "work site".

[0003] During decoration construction, workers need to carry out overall decorative work on the walls. In some basements or commercial buildings with high ceilings, when workers are working on the walls at high levels, they need to use construction auxiliary support frames. Construction auxiliary support frames are divided into fixed and mobile types. Mobile auxiliary support frames are equipped with self-locking casters at the bottom, which makes it easy for workers to move the auxiliary support frames.

[0004] However, when a worker is working alone, they need to climb down the auxiliary support frame to move the wall, release the wheels, and then push the support frame to move it. Once the wall is in the right position, the wheels need to be locked again, and then the worker needs to climb back up the support frame to continue working. If the wall is long, this process needs to be repeated, which is very cumbersome, wastes the worker's time, and reduces their efficiency. Summary of the Invention

This prevents the auxiliary support device from moving arbitrarily when the operator is working above the top support frame, thus solving the problem that it is inconvenient for a single worker to move the auxiliary support frame and that repeated climbing up and down is time-consuming, thereby improving the worker's construction efficiency.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations. Example

[0035] An auxiliary support device for building construction, such as Figure 1 , 2 As shown, it includes a bottom support frame 1. The left and right sides of the bottom support frame 1 are rotatably connected to a drive shaft 101 and a driven shaft 102, respectively. Both ends of the drive shaft 101 are fixed with drive wheels 103, and both ends of the driven shaft 102 are fixed with driven wheels 104. The bottom support frame 1 is provided with multiple bottom stiffening rods 105 to effectively connect and fix the bottom support frame 1.

[0036] like Figure 1 , 2As shown, it also includes a top support frame 2, which is placed directly above the bottom support frame 1. The four corners of the top support frame 2 and the bottom support frame 1 are connected by support columns 3, and two support columns 3 on the same side are connected by multiple support rods 301 to facilitate climbing by operators. A support plate 201 is fixed on the upper surface of the top support frame 2, and multiple top stiffening rods 208 are provided on the top support frame 2 at the lower end of the support plate 201. The multiple top stiffening rods 208 can effectively support the support plate 201, making it more stable for operators to stand on the support plate 201.

[0037] Furthermore, multiple reinforcing rods 209 are provided between the front and back of the top support frame 2 and the bottom support frame 1 to increase structural strength and make the device less prone to damage.

[0038] like Figure 1 As shown, it also includes four fixing plates 4, which are located below the bottom support frame 1.

[0039] Furthermore, it also includes a first transmission mechanism and a second transmission mechanism. The first transmission mechanism is used by the operator on the support plate 201 to control the rotation of the drive shaft 101; the second transmission mechanism is used by the operator on the support plate 201 to control the up and down movement of the fixed plate 4.

[0040] Furthermore, such as Figure 3-5 As shown, the first transmission mechanism includes a movable shaft 5, a first driving pulley 501, a first driven pulley 502, and a first transmission belt 503. A support base 504 is fixed on the support plate 201. The movable shaft 5 is rotatably connected to the support base 504. The first driving pulley 501 is fixed on the movable shaft 5, and the first driven pulley 502 is fixed on the driving shaft 101. The first driving pulley 501 and the first driven pulley 502 are connected by the first transmission belt 503.

[0041] Furthermore, such as Figure 5-8 As shown, the second transmission mechanism includes a first transmission shaft 6 and a second transmission shaft 7; a limiting shaft 601 is fixed at the upper end of the first transmission shaft 6, the limiting shaft 601 extends from below the support plate 201 to above the support plate 201, and is rotatably connected to the support plate 201; a first transmission gear 602 is fixed at the bottom of the first transmission shaft 6.

[0042] A second transmission gear 701 is fixed at the top of the second transmission shaft 7. The second transmission gear 701 is connected to the first transmission gear 602. The lower end of the second transmission shaft 7 is rotatably connected to the bottom stiffening rod 105. A horizontal rod 702 is also connected to the bottom of the second transmission shaft 7 via a transmission thread. A vertical rod 703 is fixed at the lower ends of both sides of the horizontal rod 702. The vertical rod 703 extends from the top of the bottom stiffening rod 105 to the bottom of the bottom stiffening rod 105 and can slide up and down along the bottom stiffening rod 105. A fixing plate 4 is fixed at the lower end of the vertical rod 703.

[0043] Furthermore, such as Figure 5 , 7 As shown, the second transmission mechanism also includes a synchronous transmission shaft 8. The bottom of the second transmission shaft 8 is fixed above the horizontal rod 702 with a second driving pulley 801. The top of the synchronous transmission shaft 8 is fixed with a second driven pulley 802. The second driven pulley 802 and the second driving pulley 801 are connected by a second transmission belt 803. The lower end of the synchronous transmission shaft 8 is rotatably connected to the bottom stiffening rod 105. The bottom of the synchronous transmission shaft 8 is also connected to a synchronous horizontal rod through a transmission thread. The lower end of the synchronous horizontal rod is fixed with two synchronous vertical rods. The synchronous vertical rods pass through from above the bottom stiffening rod 105 to below the bottom stiffening rod 105 and can slide up and down along the bottom stiffening rod 105. The lower end of the synchronous vertical rod is fixed with a fixed disc 4.

[0044] Furthermore, such as Figure 1 , 5 As shown in Figure -8, the second transmission mechanism also includes a positioning column 9 and a third transmission shaft 10. The bottom of the positioning column 9 is fixedly connected to the bottom support frame 1. The third transmission shaft 10 passes through the positioning column 9 in a horizontal direction and is rotatably connected to the positioning column 9. A third transmission gear 1001 is fixed at one end of the third transmission shaft 10. The first transmission gear 602 is connected to the second transmission gear 701 through the third transmission gear 1001. The first transmission gear 602, the second transmission gear 701, and the third transmission gear 1001 are all bevel gears.

[0045] Furthermore, such as Figure 1 , 9 As shown, an L-shaped protective plate 202 is slidably connected to the top support frame 2. The L-shaped protective plate 202 fits against the front and any side of the top support frame 2. Fixed rods 205 are fixed at the upper ends of the four corners of the top support frame 2. The front of the two fixed rods 205 located on the front is provided with a sliding groove 206. A slider 207 is slidably connected to the inner wall of the two sliding grooves 206. The two sliders 207 are fixedly connected to the L-shaped protective plate 202. Through the sliding grooves 206 and the sliders 207, the L-shaped protective plate 202 is more stable when sliding vertically and will not detach.

[0046] like Figure 1 , 6 As shown in Figure 8, a positioning shaft 901 is rotatably connected to the top of the positioning column 9. The positioning shaft 901 is connected to a positioning rod 902 via a transmission thread. Part of the surface of the positioning shaft 901 is provided with external threads. One end of the positioning rod 902 is fixed with a nut seat. The positioning rod 902 is threadedly connected to the positioning shaft 901 via the nut seat. The other end of the positioning rod 902 is fixedly connected to the L-shaped protective plate 202. A small gear 903 is fixed to the top of the positioning shaft 901, and a large gear 904 is fixed to the top of the first transmission shaft 6. The large gear 904 and the small gear 903 are meshed.

[0047] When the first drive shaft 6 rotates, the large gear 904 drives the small gear 903 to rotate. The circumference of the large gear 904 is much larger than that of the small gear 903. Thus, one rotation of the first drive shaft 6 can drive the positioning shaft 901 on the inner wall of the small gear 903 to rotate multiple times. This can then drive the nut seat to move vertically quickly, and in turn, drive the L-shaped protective plate 202 to move up or down quickly through the positioning rod 902.

[0048] Furthermore, such as Figure 1 As shown, a fixed baffle 203 is fixed to the back of the top support frame 2 via a fixing rod 205. An inward-opening baffle 204 is installed on the other side of the top support frame 2 via a hinge. The L-shaped protective plate 202, the fixed baffle 203, and the inward-opening baffle 204 can protect the operator on the upper surface of the support plate 201. At the same time, the inward-opening baffle 204 can rotate inward to facilitate the operator's access to and from the support plate 201.

[0049] In this embodiment, rotating handles can be fixed on the movable shaft 5, the third transmission shaft 10, and the limiting shaft 601 to facilitate operation by the operator.

[0050] The working process and principle of this embodiment are as follows: When using the device of this embodiment, the operator can climb to the top support frame 2 through the multiple support rods 301 on the support column 3, rotate the inward baffle 204 to enter the support plate 201, and perform related operations.

[0051] When the operator is on the support plate 201 and needs to move, the movable shaft 5 can be rotated to drive the first transmission belt 503 to rotate, which in turn drives the drive shaft 101 to move the drive wheel 103. Furthermore, the rotatable limit shaft 601 drives the first transmission gear 602, the second transmission gear 701, the second transmission shaft 7, the second transmission belt 803, the large gear 904, the small gear 903, and the positioning shaft 901 to rotate synchronously. Through the threaded transmission between the second transmission shaft 7 and the horizontal rod 702, and between the positioning shaft 901 and the positioning rod 902, the fixed disc 4 and the L-shaped protective plate 202 can move towards or away from each other. On the one hand, this can drive multiple fixed discs 4 to move downwards until they are tightly pressed against the ground, thereby fixing the position of the auxiliary support device, allowing the operator to move freely. When construction is carried out above the support plate 201, the auxiliary support device will not move arbitrarily. On the other hand, when multiple fixed plates 4 move downward, the L-shaped protective plate 202 moves upward simultaneously, so that the L-shaped protective plate 202 can effectively protect the operators during construction. When multiple fixed plates 4 move upward, the L-shaped protective plate 202 moves downward simultaneously. Therefore, when the operator controls the auxiliary support device to move through the first transmission mechanism, the L-shaped protective plate 202 will not obstruct the operator's view. The operator can observe the ground situation from both sides, which is convenient for control.

[0052] Furthermore, rotating the third drive shaft 10 can achieve the same effect as rotating the limit shaft 601. Since the third drive shaft 10 is mounted on the positioning column 9, the operator can also stand on the ground and manually move the auxiliary support device before fixing the position of the device through the third drive shaft 10.

[0053] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structures made using the contents of the present invention specification and drawings, whether directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of the present invention.
