Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a construction bracket with high stability. Background Art

[0002] Construction scaffolding is commonly used to assist with aerial work in municipal engineering, civil engineering, and construction, and is widely used. Existing construction scaffolding includes fixed scaffolding and mobile scaffolding. Fixed scaffolding is fixed to the ground, making it difficult to move and only suitable for assisting construction work in a specific location. Mobile scaffolding, on the other hand, can be moved around the construction site, offering greater flexibility and a wider range of applications.

[0003] Chinese utility model patent CN212002140U discloses a construction support, comprising a construction support platform, a protective net fixedly mounted on the upper surface of the construction support platform, the protective net being located around the construction support platform and perpendicular to the construction support platform, the bottom surface of the construction support platform being provided with support legs, the support legs being a rectangular parallelepiped structure, the support legs being made of metal, the interior of the support legs being hollow, the cross-section of the support legs being an inverted U-shaped structure, and there being four groups of support legs. Although the construction support can achieve flexible movement of the entire construction support through rollers, its positioning stability during construction and use is relatively poor. At the same time, during the construction process, the construction workers on the construction support need to climb down the support to obtain objects on the ground, and then climb back up to the construction support to continue construction, which is time-consuming and labor-intensive, and frequent climbing poses certain safety hazards, which also reduces construction efficiency.

[0004] Therefore, it is necessary to provide a construction support with high stability, which can solve the problems of poor positioning stability of the rollers of the construction support in the prior art, low safety and construction efficiency due to frequent climbing. Summary of the Invention

[0005] The purpose of the utility model is to provide a construction support with high stability, which can solve the problems of poor positioning stability of the rollers of the construction support in the prior art, low safety and construction efficiency due to frequent climbing.

[0006] The utility model is achieved in this way:

[0007] A highly stable construction support comprises a construction frame, a ladder, a sliding frame, support legs, a lifting drive assembly and a moving assembly; a plurality of support legs are respectively vertically mounted on the bottom of the construction frame, so that the construction frame is erected above the ground through the plurality of support legs; at least one pair of ladders is mounted on the bottom of the support frame, and the ladders extend downward to above the ground; a pair of sliding frames are respectively mounted at the two ends of the bottom of the support frame, and the moving assembly is matched and slidably arranged between the pair of sliding frames; a picking trough is formed on the construction frame, and the lifting drive assembly is connected between the moving assembly and the construction frame, so that the moving assembly can be lifted and arranged below the construction frame and its picking trough.

[0008] The construction frame includes guardrails and a standing board, a pair of guardrails are respectively arranged at the edges of the two long sides of the standing board; a retrieval groove is formed on one end of the standing board, and a number of supporting legs are vertically installed at the bottom corners of the standing board; a pair of ladders are respectively arranged at the two ends of the bottom of the standing board, and a pair of sliding frames are respectively arranged at the two ends of the bottom of the standing board.

[0009] An installation groove is formed in the construction frame along the circumference of the taking groove. A baffle is embedded in the installation groove and can close the taking groove. A pull rod is formed on the baffle.

[0010] The bottom of the supporting leg is provided with an anti-slip pad.

[0011] The sliding frame is U-shaped, with sliding grooves formed on both sides of the inner wall of the sliding frame. The moving component includes a load-bearing plate, and sliders are formed on both sides of the end of the load-bearing plate. The sliders are matched and slidably arranged in the sliding grooves, so that the load-bearing plate is slidably arranged between a pair of sliding frames.

[0012] The load-bearing plate is provided with a loading frame. When the load-bearing plate rises to the bottom of the standing plate, the loading frame is located in the taking slot. The lifting drive assembly is installed between the standing plate and the load-bearing plate.

[0013] The lifting drive assembly includes a motor, a lead screw, a transmission gear and a chain; the upper ends of a pair of lead screws are rotatably passed through the two ends of the station plate, and the lower ends of a pair of lead screws are threaded and passed through the two ends of the load-bearing plate; the motor is arranged on the station plate, and the output shaft of the motor is coaxially fixed to the upper end of one of the lead screws; a pair of transmission gears are coaxially fixed to the lower ends of the pair of lead screws and are located below the load-bearing plate, and the chain is meshed and connected between the pair of transmission gears.

[0014] A plurality of mounting blocks are respectively formed at the edges of the two long sides of the load-bearing plate, and universal wheels are installed at the bottoms of the plurality of mounting blocks.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The utility model is provided with a lifting drive assembly and a moving assembly. The motor drives the lead screw to rotate, and the threaded transmission is used to realize the lifting movement of the load-bearing plate along the axial direction of the lead screw.

DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Please see the attached Figure 1 To the attached Figure 4 A construction support with high stability includes a construction frame 1, a ladder 15, a sliding frame 2, support legs 18, a lifting drive assembly 3 and a moving assembly 4; a plurality of support legs 18 are vertically installed at the bottom of the construction frame 1, so that the construction frame 1 is erected above the ground through the plurality of support legs 18; at least one pair of ladders 15 is installed at the bottom of the supporting frame 1, and the ladders 15 extend downward to above the ground; a pair of sliding frames 2 are respectively installed at the two ends of the bottom of the supporting frame 1, and the moving assembly 4 is matched and slidably arranged between the pair of sliding frames 2; a picking groove 11 is formed on the construction frame 1, and the lifting drive assembly 3 is connected between the moving assembly 4 and the construction frame 1, so that the moving assembly 4 can be lifted and lowered below the construction frame 1 and its picking groove 11.

[0030] Preferably, the entire construction support can be made of steel, which has high structural strength and strong load-bearing capacity. The construction frame 1 can adopt a rectangular structure. Four support legs 18 can be provided and installed at the four corners of the frame to support the construction frame 1 and ensure the stability of the construction frame 1 during construction. The length of the support legs 18 can be adaptively selected according to the required construction height. The ladder 15 is used by construction workers to climb up and down the construction frame 1. The height of the ladder 15 is slightly shorter than the length of the support legs 18.

[0031] The lifting drive assembly 3 is used to drive the mobile assembly 4 up or down, and the sliding frame 2 is used to guide and limit the lifting of the mobile assembly 4, improving the stability, linearity, and controllability of the mobile assembly 4 during lifting. The mobile assembly 4 can be loaded with objects and transported to the bottom of the construction frame 1 during lifting. Construction workers on the construction frame 1 can access the objects through the access slot 11 without having to climb down from the construction frame 1, reducing the number of climbs and improving construction safety and efficiency.

[0032] Please see the attached Figure 3The construction frame 1 includes a guardrail 10 and a standing board 17. A pair of guardrails 10 are respectively arranged at the edges of the two long sides of the standing board 17; a taking groove 11 is formed on one end of the standing board 17, and a plurality of supporting legs 18 are respectively vertically installed at the bottom corners of the standing board 17; a pair of ladders 15 are respectively arranged at the two ends of the bottom of the standing board 17, and a pair of sliding frames 2 are respectively arranged at the two ends of the bottom of the standing board 17.

[0033] Guardrails 10 can be installed along the entire length of the platform 17 to provide lateral protection for the platform 17 and ensure the safety of construction workers working on the platform 17. Guardrails 10 can be constructed with horizontal and vertical bars, and the appropriate structure can be selected based on actual protection requirements. The size of the platform 17 can be adapted to the construction requirements to ensure sufficient space and platform for construction.

[0034] Please see the attached Figure 4 A mounting groove 12 is formed in the construction frame 1 along the circumference of the taking groove 11, and a baffle 13 is embedded in the mounting groove 12 and can close the taking groove 11; a pull rod 14 is formed on the baffle 13.

[0035] The mounting groove 12 is used to embed the baffle 13. The baffle 13 can be easily embedded in or removed from the mounting groove 12 through the pull rod 14, so that the baffle 13 can close the taking groove 11 after being embedded, preventing construction workers or objects from falling from the taking groove 11, thereby improving construction safety.

[0036] Preferably, the baffle 13 can also be installed in the taking slot 11 by adopting a hinged rotation opening and closing method, or can be installed by adopting other opening and closing or disassembly methods, which will not be described in detail here.

[0037] Please see the attached Figure 4 The bottom of the supporting leg 18 is provided with an anti-slip pad 16.

[0038] Accordingly, the anti-slip pad 16 can be made of a thick steel plate with a rubber pad on the bottom, which can increase the contact area and friction between the support legs 18 and the ground, thereby ensuring the erection stability of the entire construction support.

[0039] Please see the attached Figure 1 , Attachment Figure 5 and attached Figure 7 The sliding frame 2 is a U-shaped structure, and a slide groove 20 is formed on both sides of the inner wall of the sliding frame 2. The moving component 4 includes a load-bearing plate 40, and sliders 41 are formed on both sides of the end of the load-bearing plate 40. The sliders 41 are matched and slidably arranged in the slide groove 20, so that the load-bearing plate 40 is slidably arranged between a pair of sliding frames 2.

[0040] Preferably, the chute 20 and the slider 41 can adopt a T-shaped structure to ensure that the slider 41 slides stably in the chute 20 and does not fall out. The chute 20 on the inner walls of the two sides of the U-shaped structure provides sliding limit and guidance for the sliders 41 at the four corners of the load-bearing plate 40, thereby ensuring the lifting stability, linearity and controllability of the load-bearing plate 40, so that the load-bearing plate 40 can stably transport objects upward and also transport objects on the standing plate 17 downward.

[0041] Please see the attached Figure 7 The load-bearing plate 40 is provided with a loading frame 44. When the load-bearing plate 40 rises to the bottom of the standing plate 17, the loading frame 44 is located in the taking slot 11, and the lifting drive assembly 3 is installed between the standing plate 17 and the load-bearing plate 40.

[0042] The placement of the loading frame 44 facilitates the placement of objects on the load-bearing plate 40, preventing them from sliding or falling. Preferably, the size of the loading frame 44 is slightly smaller than that of the access trough 11. The loading frame 44 is mounted on the load-bearing plate 40 directly below the access trough 11, so that when the load-bearing plate 40 drives the loading frame 44 upward, it is precisely positioned within the access trough 11, making it easier for construction workers to pick up objects or place them on the loading frame 44, thereby improving the safety of transporting objects upward or downward.

[0043] Please see the attached Figure 1 and attached Figure 6 The lifting drive assembly 3 includes a motor 30, a lead screw 31, a transmission gear 32 and a chain 33; the upper ends of a pair of lead screws 31 are rotatably passed through the two ends of the station plate 17 through rotating bearings, and the lower ends of a pair of lead screws 31 are threaded and rotatably passed through the two ends of the bearing plate 40; the motor 30 is arranged on the station plate 17, and the output shaft of the motor 30 is coaxially fixedly connected to the upper end of one of the lead screws 31; a pair of transmission gears 32 are coaxially fixedly connected to the lower ends of the pair of lead screws 31 and are located below the bearing plate 40, and the chain 33 is meshed and transmitted between the pair of transmission gears 32.

[0044] Preferably, the motor 30 can adopt a motor with bidirectional rotation function in the existing technology, which is used to drive one of the screws 31 to rotate forward or reverse. The transmission gear 32 and the chain 33 have a synchronous transmission function, so that the two screws 31 can rotate synchronously.

[0045] Screw holes are opened at both ends of the load-bearing plate 40 for threaded rotation through the two screws 31. When the two screws 31 rotate synchronously, the rotation of the screws 31 is converted into axial lifting and lowering movement of the load-bearing plate 40 relative to the screws 31 through thread transmission, thereby meeting the up and down transportation needs of objects.

[0046] Please see the attached Figure 7A plurality of mounting blocks 42 are formed at the two long side edges of the load-bearing plate 40 , and universal wheels 43 are installed at the bottoms of the plurality of mounting blocks 42 .

[0047] Mounting block 42 can be integrally formed with load-bearing plate 40 and extends downwardly and outwardly of load-bearing plate 40 for mounting universal wheels 43. The number of universal wheels 43 can be adjusted based on actual movement and load-bearing requirements. Preferably, universal wheels 43 are symmetrically arranged on both sides of load-bearing plate 40.

[0048] When the load-bearing plate 40 descends, the mounting block 42 can be lowered synchronously, and the universal wheel 43 can be lowered to below the anti-slip pad 16, so that the entire construction support can be flexibly moved through the universal wheel 43; when the load-bearing plate 40 rises, the mounting block 42 can be raised synchronously, and the universal wheel 43 can be raised to above the anti-slip pad 16, so that the stability of the entire construction support can be ensured through the anti-slip pad 16.

[0049] Please see the attached Figure 1 To the attached Figure 7 , the usage method and working principle of the utility model are:

[0050] Start the motor 30 to drive one of the lead screws 31 to rotate, and utilize the meshing transmission of a pair of transmission gears 32 and a chain 33 to drive the other lead screw 31 to rotate synchronously. Under the transmission of the thread, the rotation of the pair of lead screws 31 is converted into a linear motion of the load-bearing plate 40 along the axial direction of the pair of lead screws 31, thereby realizing the lifting movement of the load-bearing plate 40.

[0051] The load-bearing plate 40 descends, causing the universal wheels 43 to touch the ground and the anti-slip pad 14 to leave the ground. The entire construction support can be moved to the required construction position through the universal wheels 43. After moving into position, the load-bearing plate 40 drives the universal wheels 43 to rise, and the anti-slip pad 14 touches the ground, ensuring that the entire construction support is stably erected at the construction position and improving construction safety.

[0052] Construction workers can use the ladder 15 to climb onto the platform 17 of the construction frame 1 and perform high-altitude construction on the platform 17. A pair of guardrails 10 provide lateral protection to ensure construction safety. During the construction process, when objects on the ground need to be accessed, the construction workers on the ground can place the objects in the loading frame 44 and use the load-bearing plate 40 to drive the loading frame 44 and the objects to the bottom of the platform 17. At the same time, the construction workers on the platform 17 use the pull rod 14 to remove the baffle 13, exposing the access slot 11, and raise the loading frame 44 into the access slot 11, making it easier for the construction workers on the platform 17 to access the objects.

[0053] After the object is removed, the load plate 40 drives the loading frame 44 down to the bottom of the standing plate 17. The construction worker on the standing plate 17 inserts the baffle 13 into the installation slot 12, closing the extraction slot 11 to prevent people or objects from falling, and then continues construction. Similarly, the loading frame 44 can also be used to transport objects on the standing plate 17 down to the ground.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
