Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a building construction frame. Background Art

[0002] During construction, local repairs and masonry work often require work at height. Tunnels and bridges often require climbing. When working at high altitudes, workers need to stand on construction scaffolding to facilitate these operations. Existing construction scaffolds are mostly rectangular frames with multiple casters with brakes at the four corners for movement. Once the scaffold is in place, it is secured using locking casters.

[0003] However, using only caster locks can cause some casters to not lock properly or fail to lock properly, causing the scaffold to shift, impacting the work of workers above the scaffold, or even causing them to fall and injure. Furthermore, the ground at the construction site may be uneven, and when the scaffold is placed on this ground, some casters may be suspended in the air, affecting the scaffold's stability and increasing the risk during construction. Utility Model Content

[0004] The main purpose of the utility model is to provide a construction frame to solve the problems in the prior art that some casters may not be locked in place or the caster locking fails, causing the construction frame to shift, affecting the work of the workers above the construction frame, and the ground at the construction site may be uneven, and when the construction frame is placed on this ground, some casters will be in a suspended state, affecting the stability of the construction frame and increasing the risk during the construction process.

[0005] In order to solve the above problems, the utility model adopts the following technical solution: a construction frame, including a frame and a plurality of support mechanisms fixed at the bottom of the frame, each of the support mechanisms including a support rod with a hollow interior and an opening at the bottom end, a sliding rod slidingly arranged inside the support rod, a lifting assembly for driving the sliding rod to rise or fall, and a moving assembly fixed on one side of the bottom of the support rod, when the bottom end of the sliding rod is located inside the support rod, the horizontal height of the bottom end of the moving assembly is lower than the horizontal height of the bottom end of the sliding rod.

[0006] Furthermore, the lifting assembly includes a screw rotatably arranged inside the support rod and a power unit for driving the screw to rotate. The sliding rod is a rod body with a hollow interior, and the top end of the sliding rod is threadedly connected to the screw.

[0007] Furthermore, the power unit includes a rocker arm inserted into one side of the support rod, one end of the rocker arm extends through the side wall of the support rod toward the interior of the support rod, and the rocker arm is rotatably connected to the support rod, a first bevel gear is fixed on the rocker arm located inside the support rod, and a second bevel gear is fixed on the top end of the screw rod, and the first bevel gear is meshed with the second bevel gear.

[0008] Furthermore, a connecting plate is fixedly provided on the upper portion of the support rod, and the top end of the screw rod is passed through the connecting plate and is rotatably connected to the connecting plate.

[0009] Furthermore, the moving assembly includes a fixed block and a roller fixed to the bottom of the fixed block, one end of the fixed block is fixedly connected to one side of the bottom of the support rod, and the other end of the fixed block extends in a direction away from the support rod.

[0010] Furthermore, the roller is a universal wheel.

[0011] Furthermore, the bottom end of the slide rod is rotatably connected to a support leg.

[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] See also Figures 1 to 3 As shown, a construction frame includes a frame 1 and a support mechanism. The frame 1 is conventional and will not be described in detail here. There are multiple support mechanisms, each used to support the frame 1 and also to move the frame 1. In this embodiment, there are four support mechanisms, each located at the four corners of the bottom of the frame 1.

[0026] Specifically, each support mechanism includes a support rod 2, a slide rod 3, a lifting assembly 4, and a moving assembly 5. The support rod 2 is a rod body with an opening at the bottom or both ends and a hollow interior. In this embodiment, the support rod 2 has a rectangular cross-section and is vertically fixed to the bottom surface of the frame 1. The outer wall of the slide rod 3 is adapted to the inner wall of the support rod 2, and the slide rod 3 is slidably arranged within the support rod 2. The lifting assembly 4 is used to drive the slide rod 3 up or down. The moving assembly 5 is fixed to one side of the bottom of the support rod 2. When the bottom end of the slide rod 3 is located inside the support rod 2, the horizontal height of the bottom end of the moving assembly 5 is lower than the horizontal height of the bottom end of the slide rod 3.

[0027] During implementation, the worker moves the slide bar 3 to the inside of the support bar 2 via the lifting assembly 4. At this time, the bottom of the moving assembly 5 is lower than the bottom of the slide bar 3. As a result, the frame 1 can be moved to the designated position via the moving assembly 5. The worker then drives the lifting assembly 4 to move the slide bar 3 downward until the bottom of the slide bar 3 is lower than the bottom of the moving assembly 5. At this point, the frame 1 is supported by the slide bar 3, while the moving assembly 5 is not in contact with the ground. This prevents the situation where individual caster locks are not in place or fail to lock, causing the construction frame to shift and affecting the work of workers above the construction frame.

[0028] In addition, by adjusting the height of each slide bar 3 of the multiple support mechanisms, it is possible to adapt to uneven ground. That is, by adjusting the height of each slide bar 3 separately, the bottom end of each slide bar 3 is stably in contact with the ground, avoiding the problem of the frame 1 shaking or tilting. Preferably, the bottom end of the slide bar 3 is rotatably connected to the support foot 6. When the bottom end of the slide bar 3 is located inside the support rod 2, the horizontal height of the bottom end of the movable assembly 5 is lower than the horizontal height of the bottom end of the support foot 6. That is, the support foot 6 is prevented from affecting the movable assembly 5 in driving the movement of the frame 1. Preferably, the bottom surface of the support foot 6 is fixed with an anti-slip pad 61. This makes the support foot 6 more stable when supporting the frame 1. In this embodiment, the material of the anti-slip pad 61 is rubber, and the side of the anti-slip pad 61 away from the support foot 6 is provided with anti-slip grooves to further prevent the frame 1 from sliding, thereby increasing the stability of the frame 1.

[0029] In this embodiment, the moving assembly 5 includes a fixed block 51 and a roller 52 fixed to the bottom of the fixed block 51. One end of the fixed block 51 is fixedly connected to one side of the bottom of the support rod 2, and the other end of the fixed block 51 extends away from the support rod 2. The fixed block 51 is provided to prevent the roller 52 from interfering with the slide bar 3 and the support leg 6. Preferably, the roller 52 is a universal wheel to facilitate the movement of the frame 1 by the staff.

[0030] See also Figure 3 As shown, in this embodiment, the lifting assembly 4 includes a screw 41 and a power unit. The screw 41 is vertically arranged in the support rod 2 and is rotatably connected to the support rod 2. Specifically, a connecting plate 21 is fixed to the upper part of the support rod 2. The top end of the screw 41 is passed through the connecting plate 21 and is rotatably connected to the connecting plate 21. The power unit is used to drive the screw 41 to rotate. The slide rod 3 is an internally hollow rod body, and the top end of the slide rod 3 is screwed to the screw 41. During implementation, the staff drives the power unit to drive the screw 41 to rotate. Since the screw 41 is screwed to the top end of the slide rod 3, and the slide rod 3 is slidably connected to the support rod 2, during the process of the screw 41 rotating forward or reverse, the slide rod 3 can be driven to rise or fall along the axial direction of the screw 41.

[0031] In this embodiment, the power unit includes a rocker 42, a first bevel gear 43, and a second bevel gear 44. The rocker 42 is Z-shaped, with one end of the rocker 42 inserted into one side of the upper portion of the support rod 2. The other end of the rocker 42 extends through the sidewall of the support rod 2 into the interior of the support rod 2 and is rotatably connected to the support rod 2. The first bevel gear 43 is fixedly mounted on the rocker 42 within the interior of the support rod 2, and the second bevel gear 44 is fixedly mounted on the top of the screw 41. The first bevel gear 43 meshes with the second bevel gear 44. During operation, a worker rotates the rocker 42, which drives the first bevel gear 43 and the second bevel gear 44 to rotate, thereby driving the screw 41 to rotate, thereby causing the slide bar 3 to rise or fall.

[0032] During the specific implementation of the present invention, the staff moves the frame 1 to the designated position by means of the roller 52 of the mobile assembly 5, and then rotates the rocker 42, which in turn drives the first bevel gear 43, the second bevel gear 44 and the screw 41 to rotate. At this time, the slide bar 3 screwed to the screw 41 moves downward until the support foot 6 contacts the ground and the roller 52 is released from the ground. At this time, the frame 1 is stably supported on the ground. It should be noted that the staff can adjust the lifting height of each slide bar 3 according to the actual situation, thereby adapting to various uneven road surfaces. That is, by setting up multiple support assemblies, the frame 1 can be stably supported, and the frame 1 can still be stably fixed on uneven road surfaces, thereby avoiding affecting the work of the staff located above the construction frame and reducing the risks during the construction process.

[0033] The above description is only a preferred embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment 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 making creative efforts are within the scope of protection of the present invention.
