Description

Technical Field

[0001] The invention relates to the technical field of scaffolds, in particular to an anti-dumping scaffold for building construction. Background Art

[0002] Scaffolding refers to various supports set up on construction sites for workers to operate and solve vertical and horizontal transportation. It is a common term in the construction industry. It refers to the use of exterior walls, interior decoration or places with high floor heights that cannot be directly constructed on construction sites. It is mainly for construction workers to work up and down or for external safety net enclosures and high-altitude installation of components. To put it bluntly, it is a frame. Scaffolding is usually made of bamboo, wood, steel pipes or synthetic materials. Some projects also use scaffolding as a template. In addition, it is also widely used in advertising, municipal administration, transportation roads and bridges, mining and other departments.

[0003] Chinese patent announcement number CN115162686B discloses a scaffold with an emergency protection device, which includes a mounting frame, a bracket and a standing board, wherein the standing board is provided with a transverse groove, the bottom of the standing board is fixedly connected to a bottom block, the transverse groove is provided with a vertical groove extending to the bottom block, the slide bar is engaged with the groove, the slide bar moves away from each other under the action of spring 1, under the action of spring 5, one end of the rotating arm close to the disc abuts against the mounting frame, and under the action of spring 4, the disc approaches the mounting frame, at this time, the round rod extends into the through hole provided at the end of the arc plate, and the baffle plate is opened due to rotation, thereby reducing the contact distance between the scaffold and the ground when the scaffold is overturned, so that the overturning distance of the scaffold is limited, and the scaffold will not directly overturn and tilt 90 degrees. Therefore, after the scaffold is overturned, the construction personnel can still stand on the standing board under the action of the baffle plate, which plays a role in protecting the safety of the construction personnel on the scaffold;

[0004] The above technology adds an additional manual supporting structure to the traditional scaffolding, which not only makes the operation process cumbersome and complicated, but also affects the balance of the scaffolding. Once the danger of overturning occurs, it is difficult for construction workers to maintain balance on the scaffolding, and they are prone to falling. For this reason, the present invention discloses an anti-overturning scaffold for construction to solve the above problem. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the problem that traditional scaffolds are difficult to maintain balance and are prone to falling hazards, and to provide an anti-dumping scaffold for construction, thereby solving the above problem.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an anti-dumping scaffold for construction, comprising a scaffold support, a rotatable safety hanging basket is installed between the two ends of the scaffold support, a grid frame is fixedly arranged between the inner walls on both sides of the scaffold support, safety ladders are installed on both sides of the grid frame, diagonal bracing mechanisms are installed between the safety ladder and the bottom wall of the scaffold support, and straightening mechanisms are installed at the four corners of the scaffold support.

[0007] Furthermore, the safety ladder includes two connecting blocks installed on the side walls of the grid frame, and the connecting blocks are rotatably connected to vertical plates. The bottom ends of the vertical plates are provided with grooves, and support plates are rotatably connected between the inner walls on both sides of the grooves. The lower sides of the support plates are densely covered with multiple anti-slip protrusions, and multiple horizontal plates are fixedly connected between the two vertical plates.

[0008] Furthermore, the diagonal bracing mechanism includes a T-shaped slide groove located on the side of the vertical plate facing the scaffolding support, an adapting recessed block is slidably connected in the T-shaped slide groove, a support pin is rotatably connected between the inner walls on both sides of the adapting recessed block, a locking card is fixedly connected to the outer side of the support pin, a plurality of grooves are equidistantly provided on the T-shaped slide groove, the support pin extends into the groove, and a slope surface is provided on the lower side of the groove.

[0009] Furthermore, the adapting recessed block is hingedly connected with an oblique support plate on one side away from the vertical plate, and the bottom end of the oblique support plate is rotatably connected with a positioning block, and the positioning block is fixed on the bottom wall of the safety hanging basket.

[0010] Furthermore, the straightening mechanism includes a hollow tube fixedly embedded on the scaffolding support, an arc rod is fixedly connected between the end of the hollow tube and the scaffolding support, a guide plate is slidably embedded on the side of the hollow tube away from the scaffolding support, a plurality of through holes are equidistantly provided on the guide plate, and positioning holes are provided on both sides of the end of the hollow tube corresponding to the through holes, so that the hollow tube and the guide plate can be screwed fixed to form an integrated structure.

[0011] Furthermore, safety handrails are fixedly provided on both sides of the safety hanging basket, a railing is fixedly connected between the lower side of the safety handrail and the bottom wall of the safety hanging basket, both ends of the upper side of the safety hanging basket are fixedly connected with shaft rods, the shaft rods pass through the scaffolding support and extend to the assembly box where they are fixedly connected with friction wheels, the outer sides of the friction wheels are sleeved with assembly boxes, the assembly boxes are fixed to the scaffolding support, and springs are fixedly connected to the inner walls of the four sides of the assembly box, the ends of the springs are fixed with arc-shaped friction plates, telescopic rods are sleeved in the springs, and the two ends of the telescopic rods are respectively fixedly connected to the assembly box and the arc-shaped friction plate.

[0012] Furthermore, the grid frame is composed of a plurality of longitudinal plates fixedly connected between the inner walls on both sides of the scaffolding support and a plurality of connecting plates running through the longitudinal plates, wherein the longitudinal plates and the connecting plates are perpendicular to each other, and the longitudinal plates and the connecting plates are welded and fixed into an integral structure, and the connecting block is fixed to the outermost longitudinal plate.

[0013] Furthermore, one end of the guide plate away from the hollow cylinder is threadedly connected to a screw rod, the bottom end of the screw rod is fixedly connected to a mounting plate, a universal wheel is screwed fixed to the lower side of the mounting plate, and a wheel brake is installed on the universal wheel.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention provides an anti-dumping scaffold for construction. The guide plates in each hollow tube are pulled out until the through holes and the positioning holes are aligned with each other. The maximum extension length of the guide plates is limited by the size of the work site. After the bolts are passed through the through holes and the positioning holes and matched with the nut threads, the extension length of the guide plates can be positioned. The wheel brakes on the universal wheels are locked to position the scaffold support. The longer guide plates can increase the stability of the scaffold support to prevent the scaffold support from tipping over.

[0016] 2. The present invention provides an anti-tilt scaffold for construction. Workers can climb to the safety hanging basket to carry out construction work through the safety ladder. If the scaffold accidentally falls, the safety ladder will always be perpendicular to the ground under the action of gravity. During this process, the diagonal support plate will tilt synchronously, the adapting concave block will slide downward along the T-shaped slide groove, and the supporting pin will pass through a plurality of grooves until the supporting foot plate horizontally contacts the ground. The anti-skid protrusions can ensure that there is sufficient friction between the supporting foot plate and the ground to prevent the scaffold from being excessively displaced due to the impact force after it falls. The supporting pin will conflict with the flat surface of the groove to prevent the safety ladder from folding inwards. The scaffold as a whole forms a "right-angle triangle structure", which avoids the situation where the scaffold is completely overturned, killing two birds with one stone.

[0017] 3. The present invention provides an anti-dumping scaffold for construction. If the scaffolding accidentally dumps, the safety hanging basket is always perpendicular to the ground under the action of gravity. The dumping of the scaffolding will only cause the construction workers to move away from the working area and will not cause the construction workers to fall. It is worth noting that under the action of the spring elastic force, the arc-shaped friction plate can press the friction wheel tightly, which can increase the resistance of the safety hanging basket to swing, so that the construction workers can work stably under normal working conditions.

[0033] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0034] Example 1: Figures 1 to 8 As shown, the present embodiment discloses an anti-dumping scaffold for construction, comprising a scaffold support 1, a rotatable safety hanging basket 2 is installed between the two ends of the scaffold support 1, safety handrails 21 are fixedly arranged on both sides of the safety hanging basket 2, a railing 22 is fixedly connected between the lower side of the safety handrail 21 and the bottom wall of the safety hanging basket 2, and shaft rods 23 are fixedly connected to the two ends of the upper side of the safety hanging basket 2, and the shaft rods 23 pass through the scaffold support 1 and extend to the assembly box 25 and are fixedly connected to the friction wheel 24, and the outer side of the friction wheel 24 is sleeved with an assembly box 25, and the assembly box 25 is fixed to the scaffold support 1, and springs 26 are fixedly connected to the inner walls of the four sides of the assembly box 25, and arc-shaped friction plates 27 are fixed to the ends of the springs 26, and telescopic rods 28 are sleeved in the springs 26, and the two ends of the telescopic rods 28 are respectively fixedly connected to the assembly box 25 and the arc-shaped friction plate 27;

[0035] Specifically, the safety handrail 21 can provide protection for construction workers, and can provide support and a safe gripping point for construction workers to prevent them from accidentally falling. Under the elastic force of the spring 26, the arc-shaped friction plate 27 can press the friction wheel 24 tightly, which can increase the resistance to the swing of the safety hanging basket 2, so that construction workers can work stably under normal working conditions.

[0036] Furthermore, a grid frame 3 is fixedly arranged between the inner walls on both sides of the scaffold support 1, and the grid frame 3 is composed of a plurality of longitudinal plates 31 fixedly connected between the inner walls on both sides of the scaffold support 1 and a plurality of connecting plates 32 running through each longitudinal plate 31, wherein the longitudinal plates 31 and the connecting plates 32 are perpendicular to each other, and the longitudinal plates 31 and the connecting plates 32 are welded and fixed to form an integral structure, and the connecting block 41 is fixed to the outermost longitudinal plate 31;

[0037] Specifically, the longitudinal plates 31 and the connecting plates 32 are staggered to form a grid structure, which plays a role in reinforcing the scaffold support 1. Workers can rely on the grid frame 3 to climb into the safety hanging basket 2. It can also be used to place construction tools and provide a passage for the upper and lower safety hanging baskets 2.

[0038] Further, a safety ladder 4 is installed on both sides of the grid frame 3, and the safety ladder 4 includes two connecting blocks 41 installed on the side walls of the grid frame 3, and the connecting blocks 41 are rotatably connected to a vertical plate 42, and the bottom ends of the vertical plates 42 are provided with a notch, and the inner walls on both sides of the notch are rotatably connected to a foot plate 43, and the lower side of the foot plate 43 is densely covered with a plurality of anti-slip protrusions 44, and a plurality of horizontal plates 45 are fixedly connected between the two vertical plates 42;

[0039] Specifically, workers can climb up to the safety hanging basket 2 to carry out construction work through the safety ladder 4. When the scaffolding collapses, the safety ladder 4 is always perpendicular to the ground, so that the support plate 43 at the bottom of the safety ladder 4 can contact the ground first, and the anti-slip protrusion 44 can ensure that there is sufficient friction between the support plate 43 and the ground to prevent the scaffolding from being excessively displaced due to the impact force after it collapses.

[0040] Furthermore, a diagonal bracing mechanism 5 is installed between the safety ladder 4 and the bottom wall of the scaffold support 1, and the diagonal bracing mechanism 5 includes a T-shaped slide groove 51 located on the side of the vertical plate 42 facing the scaffold support 1, and an adapting recessed block 52 is slidably connected in the T-shaped slide groove 51, and a supporting pin 53 is rotatably connected between the inner walls on both sides of the adapting recessed block 52, and a locking card 54 is fixedly connected to the outer side of the supporting pin 53, and a plurality of grooves 55 are equidistantly provided on the T-shaped slide groove 51, and the supporting pin 53 extends into the groove 55, and a slope surface 56 is provided on the lower side of the groove 55, and a diagonal bracing plate 57 is hinged on the side of the adapting recessed block 52 away from the vertical plate 42, and a positioning block 58 is rotatably connected to the bottom end of the diagonal bracing plate 57, and the positioning block 58 is fixed on the bottom wall of the safety hanging basket 2;

[0041] Specifically, if the scaffolding accidentally topples over, the safety ladder 4 will always be perpendicular to the ground under the action of gravity, and the diagonal support plate 57 will tilt synchronously, forming a "right-angled triangle structure" as a whole, thereby preventing the scaffolding from completely tipping over. During this process, the adapter block 52 will slide downward along the T-shaped slide groove 51, and the support pin 53 will pass over multiple grooves 55 until the support plate 43 horizontally contacts the ground. At this time, the support pin 53 will conflict with the flat surface of the groove 55, thereby preventing the safety ladder 4 from folding inward.

[0042] Further, the four corners of the scaffold support 1 are equipped with a straightening mechanism 6, and the straightening mechanism 6 includes a hollow tube 61 fixedly embedded on the scaffold support 1, and an arc rod 62 is fixedly connected between the end of the hollow tube 61 and the scaffold support 1, and a guide plate 63 is slidably embedded on the side of the hollow tube 61 away from the scaffold support 1, and a plurality of through holes 64 are equidistantly opened on the guide plate 63, and positioning holes 65 are opened on both sides of the end of the hollow tube 61 corresponding to the through holes 64, so that the hollow tube 61 and the guide plate 63 can be screwed fixed as an integrated structure;

[0043] Specifically, the guide plates 63 in each hollow tube 61 are pulled out until the through holes 64 and the positioning holes 65 are aligned with each other. The maximum extension length of the guide plates 63 is limited by the size of the work site. After the bolts are passed through the through holes 64 and the positioning holes 65 and matched with the nut threads, the extension length of the guide plates 63 can be positioned, and the wheel brakes on the universal wheels 68 can be locked to position the scaffold support 1. The longer guide plates 63 can increase the stability of the scaffold support 1 to prevent the scaffold support 1 from tipping over.

[0044] Furthermore, one end of the guide plate 63 away from the hollow cylinder 61 is threadedly connected with a screw rod 66, the bottom end of the screw rod 66 is fixedly connected with a mounting plate 67, a universal wheel 68 is screwed fixed to the lower side of the mounting plate 67, and a wheel brake is installed on the universal wheel 68;

[0045] Specifically, a wheel brake is installed on the universal wheel 68 to fix the position of the scaffolding when necessary to prevent movement. By rotating the mounting plate 67, the extension length of the guide plate 63 can be adjusted so that the scaffolding support 1 can maintain a horizontal state on an uneven construction ground to prevent the scaffolding from overturning.

[0046] Working principle: When in use, first push the scaffold support 1 to the working position, pull out the guide plate 63 in each hollow tube 61 until the through hole 64 and the positioning hole 65 are aligned with each other, and the maximum extension length of the guide plate 63 is limited by the size of the work site. After the bolt passes through the through hole 64 and the positioning hole 65 and cooperates with the nut thread, the extension length of the guide plate 63 can be positioned, and the wheel brake on the universal wheel 68 can be locked to position the scaffold support 1. The longer guide plate 63 can increase the stability of the scaffold support 1 to prevent the scaffold support 1 from tipping over. The staff can climb to the safety hanging basket 2 through the safety ladder 4 to carry out construction work. If the scaffold accidentally tips over, the safety ladder 4 will always be perpendicular to the ground under the action of gravity. During this process, the diagonal support plate 57 will tilt synchronously, and the adapter concave block 52 will move along the T-shaped slide groove 5 1 slides downward, the support pin 53 passes over the multiple grooves 55 until the foot plate 43 contacts the ground horizontally, and the anti-skid protrusion 44 can ensure that there is enough friction between the foot plate 43 and the ground to prevent the scaffold from being excessively displaced due to the impact force after the scaffolding falls. The support pin 53 conflicts with the flat surface of the groove 55, which can prevent the safety ladder 4 from folding inward. The scaffolding as a whole forms a "right-angled triangle structure" to avoid the scaffolding from completely overturning. On the other hand, the safety hanging basket 2 is always perpendicular to the ground under the action of gravity. The overturning of the scaffolding will only cause the construction workers to stay away from the working area, and will not cause the construction workers to fall. It is worth mentioning that under the elastic force of the spring 26, the arc-shaped friction plate 27 can press the friction wheel 24 tightly, which can increase the resistance of the swing of the safety hanging basket 2, so that the construction workers can work stably under normal working conditions.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
