Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a load-bearing support. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction. The site where construction work takes place is called the "construction site" or "building site."

[0003] In engineering construction, load-bearing supports are widely used. However, traditional load-bearing supports have drawbacks when used and stored in large-scale projects, such as multiple disassembly and assembly or the need to invest a large amount of support materials at once. This results in a long support erection period and high labor intensity for workers. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a load-bearing support.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A load-bearing bracket includes a fixed base, a load-bearing platform on the top of the fixed base, vertical plates welded to both ends of the load-bearing platform, a supporting column between the fixed base and the load-bearing platform, and casters at the four corners of the bottom of the fixed base. The bracket also includes:

[0007] The first auxiliary support column has one end installed on the support column and the other end movably installed on the fixed base to support the support column.

[0008] Telescopic plate, which is slidably mounted on the load-bearing platform, is used to extend the length of the load-bearing platform;

[0009] The second auxiliary support column has one end installed on the telescopic plate and the other end installed on the vertical plate, and is used to support the telescopic plate.

[0010] The shock absorption mechanism, located on the caster wheel, is used for shock absorption of the load-bearing support.

[0011] Furthermore, a first lead screw is rotatably installed inside the support platform, a first slider sleeved on the first lead screw is rotatably installed at the top of the support column, and a first support block fixed to the fixed base is rotatably installed at the bottom of the support column.

[0012] Furthermore, the first auxiliary support column includes a first auxiliary support rod rotatably disposed with respect to the support column. A limiting block is rotatably disposed at the end of the first auxiliary support rod away from the support column and slidably disposed with respect to the fixed base. The limiting block is fixed to the fixed base by a positioning rod.

[0013] Furthermore, a second lead screw is rotatably installed inside the side wall of the load-bearing platform, and a second slider sleeved on the second lead screw is fixedly connected to both sides of the telescopic plate.

[0014] Furthermore, the second auxiliary support includes a second auxiliary support rod, with a fixing block rotatably disposed at the top end of the second auxiliary support rod, the fixing block being fixed to the bottom of the telescopic plate, and a limit component rotatably disposed at the bottom end of the second auxiliary support rod, the limit component being slidably connected to the vertical plate.

[0015] Furthermore, the limiting component includes a fixed frame rotatably mounted with the second auxiliary support rod, a gear rotatably mounted inside the fixed frame, a motor for driving the gear to rotate mounted on the fixed frame, a ruler strip meshing on both sides of the gear, and a slot for cooperating with the ruler strip being opened in the vertical plate.

[0016] Furthermore, the shock absorption mechanism includes a fixed sleeve located on the caster wheel, a shock absorption rod fixed to the bottom of the fixed base is inserted into the fixed sleeve, a shock absorption spring is sleeved on the shock absorption rod, and the fixed base is connected to the fixed sleeve through the shock absorption spring.

[0017] Furthermore, auxiliary support components are provided on both sides of the fixed base. The top of the auxiliary support components is fixedly connected to the load-bearing platform, and several climbing frames are distributed on the surface of the auxiliary support components.

[0018] Furthermore, the auxiliary support assembly includes a sleeve plate fixed to the fixed base and a fixed plate fixed to the load-bearing platform. The bottom end of the fixed plate is fixedly connected to an auxiliary support plate inserted into the sleeve plate. Limiting holes are provided on both the auxiliary support plate and the sleeve plate, and limiting rods are inserted into the limiting holes.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. This invention features an adjustable support column. When the first lead screw rotates, the support column can be deflected by the first slider. In use, the support platform can be pushed upwards and its height can be adjusted. When not in use, the support platform descends and fits against the fixed base, making it easy to fold and store the support bracket.

[0021] 2. The present invention provides a telescopic plate on the load-bearing platform, which can extend the length of the weighing platform laterally as needed. Furthermore, the bottom of the telescopic plate is provided with a second auxiliary support rod for support. When the telescopic plate extends outward, it will pull the second auxiliary support rod. After the extension is completed, the motor drives the gear to rotate, which allows the ruler strips at both ends to be inserted into the corresponding slots for limiting and providing support for the telescopic plate.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0034] Reference Figures 1-8 As shown, a load-bearing bracket includes a fixed base 1, a load-bearing platform 2 on the top of the fixed base 1, vertical plates 20 welded to both ends of the load-bearing platform 2, a support column 3 between the fixed base 1 and the load-bearing platform 2, the support column 3 being able to deflect for supporting the load-bearing platform 2 and adjusting its height, and casters 5 at the four corners of the bottom of the fixed base 1, allowing the load-bearing bracket to be moved directly by pushing it, which is convenient and quick; it also includes:

[0035] The first auxiliary support column has one end installed on the support column 3 and the other end movably installed on the fixed base 1. When the support column 3 is deflected, the bottom end of the first auxiliary support column will also slide on the fixed base 1 to support the support column 3.

[0036] The telescopic plate 6 is slidably mounted on the load-bearing platform 2. The telescopic plate 6 can extend to both ends to stretch the length of the entire load-bearing platform 2.

[0037] The second auxiliary support 7 has one end installed on the telescopic plate 6 and the other end installed on the vertical plate 20. When the telescopic plate 6 extends outward, it will also pull the second auxiliary support 7, so that the bottom end of the second auxiliary support 7 slides along the vertical plate 20. After the telescopic plate 6 is stretched, the bottom end of the second auxiliary support 7 will be fixed to the vertical plate 20 to support the telescopic plate 6.

[0038] The shock absorption mechanism 8, located on the caster wheel 5, is used for shock absorption of the load-bearing bracket.

[0039] In one embodiment, a first lead screw 21 is rotatably installed inside the support platform 2. One end of the first lead screw 21 is equipped with a motor for driving the first lead screw 21. A first slider 22 is rotatably installed on the top of the support column 3 and fitted onto the first lead screw 21. A first support block 31 is rotatably installed on the bottom of the support column 3 and fixed to the fixed base 1. When the support platform 2 needs to be used, the first lead screw 21 can be started first. Under the rotation of the first lead screw 21, the first slider 22 is driven to slide to the end, thereby causing the top of the support column 3 to deflect upward, raising the support platform 2. One end of the first auxiliary support column will also deflect with the support column 3. At the same time, the other end of the first auxiliary support column will slide on the fixed base 1. After the support platform 2 is raised to a suitable height, the bottom end of the first auxiliary support column can be fixed to the fixed base 1 to support the support column 3.

[0040] In one embodiment, the first auxiliary support includes a first auxiliary support rod 32 rotatably disposed with the support column 3. A limiting block 33 rotatably disposed at the end of the first auxiliary support rod 32 away from the support column 3 and slidably disposed with the fixed base 1. The limiting block 33 is fixed to the fixed base 1 by a positioning rod 34. When the support column 3 deflects upward, it will also pull the first auxiliary support rod 32 to deflect, thereby allowing the limiting block 33 to slide along the fixed base 1. After the support column 3 stops, the positioning rod 34 can be screwed down to fix the limiting block 33, thereby supporting the support column 3.

[0041] In one embodiment, a second lead screw 23 is rotatably installed inside the side wall of the support platform 2. One end of the second lead screw 23 is also equipped with a motor for driving the second lead screw 23 to rotate. Both sides of the telescopic plate 6 are fixedly connected with second sliders 61 sleeved on the second lead screw 23. When it is necessary to extend outward, the motor can be started to drive the second lead screw 23 to rotate, thereby driving the telescopic plate 6 to move outward. The second auxiliary support column 7 is located at the bottom of the outer end of the telescopic plate 6.

[0042] In one embodiment, the second auxiliary support 7 includes a second auxiliary support rod 71. A fixing block 72 is rotatably provided at the top of the second auxiliary support rod 71, and the fixing block 72 is fixed to the bottom of the telescopic plate 6. A limiting component 73 is rotatably provided at the bottom of the second auxiliary support rod 71. The limiting component 73 is slidably connected to the vertical plate 20. Similar to the first auxiliary support, when the telescopic plate 6 moves outward, it will pull the second auxiliary support rod 71. The bottom of the second auxiliary support rod 71 slides upward along the vertical plate 20. After the telescopic plate 6 stops, it can be fixed to the vertical plate 20 by the limiting component 73, so that the second auxiliary support rod 71 supports the telescopic plate 6.

[0043] In one embodiment, the limiting component 73 includes a fixed frame 731 rotatably disposed with the second auxiliary support rod 71. A gear 732 is rotatably disposed inside the fixed frame 731. A motor 733 for driving the gear 732 to rotate is mounted on the fixed frame 731. Ruler strips 734 are meshed on both sides of the gear 732. A slot 201 that cooperates with the ruler strips 734 is opened in the vertical plate 20. By driving the gear 732 to rotate through the motor 733, the ruler strips 734 on the upper and lower sides can be moved so that the ruler strips 734 can be inserted into the slot 201 for fixation.

[0044] In one embodiment, the shock absorption mechanism 8 includes a fixed sleeve 81 located on the caster wheel 5. A shock absorption rod 82 fixed to the bottom of the fixed base 1 is inserted into the fixed sleeve 81. A shock absorption spring 83 is sleeved on the shock absorption rod 82. The fixed base 1 is connected to the fixed sleeve 81 through the shock absorption spring 83. This mechanism can buffer the entire load-bearing bracket and provide a certain shock absorption effect when the load-bearing bracket moves.

[0045] In one embodiment, auxiliary support components 4 are provided on both sides of the fixed base 1. The top of the auxiliary support component 4 is fixedly connected to the support platform 2 and is used to support the middle part of the support platform 2. Several climbing frames 9 are distributed on the surface of the auxiliary support component 4. If personnel need to go up or down in the middle, they can move through the climbing frames 9. The climbing frames 9 are hidden, that is, the climbing frames 9 can be flipped upward and stored in the auxiliary support component 4 for hiding.

[0046] In one embodiment, the auxiliary support assembly 4 includes a sleeve plate 41 fixed to the fixed base 1 and a fixed plate 42 fixed to the load-bearing platform 2. The bottom end of the fixed plate 42 is fixedly connected to an auxiliary support plate 43 inserted into the sleeve plate 41. Both the auxiliary support plate 43 and the sleeve plate 41 have limit holes 431. Limiting rods 44 are inserted into the limit holes 431. After the load-bearing platform 2 is moved upward, the fixed plate 42 moves upward along with the auxiliary support plate 43. Then, by inserting the limiting rods 44, the auxiliary support plate 43 is fixed to the sleeve plate 41. When storing, the load-bearing platform 2 moves downward, and the auxiliary support plate 43 moves downward along the sleeve plate 41. Then, by inserting the limiting rods 44 again, the load-bearing platform 2 can be fixed, thereby improving stability.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
