Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a movable cantilever frame used for high-altitude construction of building engineering. Background Art

[0002] A construction project refers to an engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. When the main body of the building is completed, construction such as decoration and electromechanical installation is required. Some construction areas are irregular, which makes it difficult for existing movable lifting scaffolds to construct in irregular construction areas after being raised to high altitudes due to limited space on the operating platform.

[0003] After searching for a utility patent with patent number CN217175604U, a movable cantilever frame for high-altitude construction of construction projects is disclosed, including a lift, the upper surface of the lift is fixedly connected to an installation box, the inner bottom wall of the installation box is respectively fixedly connected to a motor and a first operating platform, the output end of the motor is fixedly connected to a first bevel gear, the upper surface of the installation box is rotatably connected to a second operating platform, the lower surface of the second operating platform is fixedly connected to a rotating disk, the lower end of the rotating disk extends to the inner wall of the installation box, and is fixedly connected to a second bevel gear meshing with the first bevel gear, and the upper surface of the second operating platform is fixedly connected to a connecting frame.

[0004] Compared with the prior art, the utility model patent with patent number CN217175604U is a movable cantilever frame used for high-altitude construction of construction projects. By setting an extension platform, when encountering an irregular construction area, the extension platform is pushed to unfold the extension platform, and the extension platform is fixed with locking bolts. The driving motor drives the second operating platform to rotate, thereby driving the extension platform to rotate to the irregular construction area, so that construction can be carried out in the irregular construction area.

[0005] However, in the above scheme, an extension platform is set up. When an irregular construction area is encountered, the extension platform is pushed to unfold the extension platform, and the extension platform is fixed with locking bolts. The driving motor drives the second operating platform to rotate, thereby driving the extension platform to rotate to the irregular construction area. However, when the extension platform is used, on the one hand, the mass of the base will increase when the extension platform is used to accommodate a standing person. On the other hand, when the motor is used to rotate, the extension platform needs to bear the weight of the standing person while rotating, which greatly increases the risk of rotation. Therefore, a movable cantilever frame for high-altitude construction of construction projects is proposed. Utility Model Content

[0006] The utility model aims to solve the problem in the prior art that construction safety must be ensured during construction of a building project, and safety must be ensured when working at high altitudes, so a movable cantilever for high-altitude construction of a building project is proposed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A movable cantilever frame for high-altitude construction of a building project, comprising a second movable frame, a bearing plate fixedly connected to the side wall of the second movable frame, a slide plate fixedly connected to the top of the bearing plate, a fixed plate slidably connected to the top of the slide plate, a force block slidably connected to the bottom of the fixed plate, and a first movable frame fixedly connected to the side wall of the force block;

[0009] A sliding mechanism for sliding the second movable frame is provided at the bottom of the first movable frame, and the sliding mechanism includes a second worm gear inside the first movable frame, one side of the second worm gear is fixedly connected to the first worm gear, the first worm gear is fixedly connected to the second movable frame, a side wall of the second worm gear away from the first worm gear is meshedly connected to a worm, and the sides of the worm gear are respectively rotatably connected to the first movable frame.

[0010] The above technical solution further includes:

[0011] The bottom of the first movable frame is fixedly connected with an inner sliding block, and a bottom groove for worm rotation is arranged on one side of the bottom of the first movable frame away from the inner sliding block.

[0012] The bottom of the second movable frame is fixedly connected to the first outer sliding block, and the side of the bottom of the second movable frame away from the first outer sliding block is fixedly connected to the second outer sliding block.

[0013] The first worm gear is fixedly connected to a connecting column, and the connecting column is fixedly connected to the second worm gear.

[0014] The side wall of the fixed plate is provided with a limiting groove for sliding of the slide plate, and the limiting groove is fixedly connected to the fixed plate.

[0015] The fixing plate is rotatably connected to a limiting groove inside, and a shock absorbing spring is arranged inside the limiting groove.

[0016] A plurality of groups of shock absorbing springs are arranged inside the limiting groove, and a bearing steel ball for the rotation of the limiting groove is arranged inside the inner ring.

[0017] The utility model has the following beneficial effects:

[0018] 1. In the utility model, the second worm gear is installed and connected to the bottom of the second movable frame. Since one side of the second worm gear is fixed to the bottom of the first movable frame, the other side, namely the first worm gear, will rotate with the second worm gear. The first worm gear is fixed to the bottom of the second movable frame. When the second worm gear rotates, it is meshed and connected with the worm surface inside the first movable frame. When the second worm gear rotates, the second movable frame will move away from the first movable frame. When the second worm gear rotates in the opposite direction, the second movable frame will move closer to the first movable frame. When the second movable frame slides to the side wall of the first movable frame, the side wall of the inner slider is provided with a groove for sliding the first outer slider, which increases the stability of the first movable frame and the second movable frame, thereby enabling workers to work stably.

[0019] 2. When a longer working area is required at high altitude, it is achieved by moving the second movable frame away from the first movable frame. At this time, the fixed plate is stretched to slide on the side of the skateboard. When the fixed plate slides to the side close to the first movable frame, the fixed plate is supported by the force block extending to the surface of the first movable frame. When sliding, a bearing plate is provided at the bottom of the skateboard. When the skateboard and the fixed plate slide, the outer ring inside the fixed plate can provide a certain protection for the fixed plate. A circle of shock-absorbing springs is provided inside the outer ring to support the steel ring on the side of the inner ring. The bottom of the steel ring is supported by bearing steel balls. While ensuring the normal sliding of the fixed plate and the skateboard, the impact force when the fixed plate slides to one side of the skateboard can be reduced, thereby increasing the service life of the fixed plate and the skateboard.

[0020] 3. In the utility model, the first outer sliding block and the second outer sliding block are provided so that the first movable frame and the second movable frame can be stably combined during the insertion process, which is used to adjust the working surface for workers. A limiting groove is provided on the side wall of the fixed plate to prevent the problem of too fast sliding when the fixed plate slides on the side of the slide plate. The setting of the limiting groove ensures the safety during use. Under normal circumstances, the first movable frame and the second movable frame are difficult to separate under human pulling. The pulling stability is ensured by providing a worm gear on the side of the first movable frame and the second movable frame. The worm gear is controlled by a motor to prevent serious consequences caused by human pulling. BRIEF DESCRIPTION OF THE DRAWINGS
