Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, specifically a lifting mechanism for construction. Background Technology

[0002] With the acceleration of urbanization, high-rise buildings are springing up like mushrooms after rain, and the difficulty and complexity of construction are increasing day by day. The traditional methods of relying on scaffolding, simple suspended baskets or manual climbing and carrying of materials can no longer meet the requirements of efficient and safe construction. In many processes such as facade construction, curtain wall installation and water, electricity, heating and ventilation pipe laying of high-rise buildings, construction workers need to work frequently at different heights and need to transport a large amount of building materials and construction equipment to designated floors in a timely and accurate manner. This urgently requires a professional lifting mechanism that can lift stably, has an adaptable load-bearing capacity, and is easy to operate, in order to improve construction efficiency, ensure construction safety, and ensure that construction projects are completed on time and with high quality.

[0003] Existing guard plates are mainly set around the perimeter of the lifting platform, and their protective height and area are fixed. For some tools that accidentally fall from a high position with a certain initial horizontal velocity, they will exceed the protection range of the guard plate and smash into the components below, such as scissor lifts, hydraulic cylinders, and fixed components. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting mechanism for building construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting mechanism for building construction, comprising:

[0006] A fixed frame, on which fasteners are fixedly connected;

[0007] A transmission assembly is placed on a fixed frame. The transmission assembly includes a first rotating shaft rotatably connected to the fixed frame, a lifting rod rotatably connected to the first rotating shaft, a worktable slidably connected to the lifting rod, a second transmission rod fixedly connected to the worktable, a third transmission rod rotatably connected to the second transmission rod, a third transmission rod slidably connected to the third transmission rod, and a fourth transmission rod rotatably connected to the end of the third transmission rod away from the first transmission rod. The fourth transmission rod is fixedly connected to the fixed frame.

[0008] A mechanical telescopic rod is fixedly connected to the third transmission rod, a third rotating shaft is rotatably connected to the mechanical telescopic rod, a fifth transmission rod is rotatably connected to the third rotating shaft, a sixth transmission rod is fixedly connected to the fifth transmission rod, a first fixed rod is rotatably connected to the sixth transmission rod, a second fixed rod is fixedly connected to the first fixed rod, a placement frame is slidably connected to the second fixed rod, and a guardrail is fixedly connected to the workbench.

[0009] Furthermore, the second transmission rod is rotatably connected to the third transmission rod via a fourth rotating shaft, and both ends of the third transmission rod are rotatably connected to the fourth rotating shaft. The end of the third transmission rod away from the second transmission rod is rotatably connected to the fourth transmission rod via the fourth rotating shaft.

[0010] The above technical solution is adopted so that when the third transmission rod is driven to move, it will pull or push out the first transmission rod to realize the transmission of the first transmission rod.

[0011] Furthermore, a sliding groove is provided on the fixed frame, and the first transmission rod is slidably connected in the sliding groove on the fixed frame.

[0012] The above technical solution is adopted: by opening a sliding groove on the fixed frame, the sliding of the first transmission rod is guided during use.

[0013] Furthermore, a fixed chamber is fixedly connected to the fixed frame, a second rotating shaft is rotatably connected to the fixed chamber, and the third transmission rod is rotatably connected to the second rotating shaft.

[0014] The above technical solution involves a fixed compartment that is fixedly connected to the fixed frame, which facilitates the rotation of the third transmission rod during use.

[0015] Furthermore, a storage compartment is fixedly connected to the fixed frame, a flexible steel wire rope is fixedly connected inside the storage compartment, a baffle plate is fixedly connected to the flexible steel wire rope, and the end of the flexible steel wire rope away from the storage compartment is fixedly connected to the first transmission rod.

[0016] The above technical solution is adopted: by fixing a storage compartment to the fixed frame, it is convenient to connect the cover plate when in use. After the cover plate is pulled out, it can protect the internal components of the fixed frame.

[0017] Furthermore, the fixed chamber has an opening, and the baffle plate and flexible steel wire rope that are slidably connected inside the fixed chamber are slidably connected in the opening on the fixed chamber.

[0018] The above technical solution is adopted: by opening the fixed compartment, the obstruction of the baffle plate and the flexible steel wire rope is avoided during use.

[0019] Furthermore, the placement frame on the third transmission rod is fixedly connected to the workbench, and a damper is fixedly connected to the placement frame on the third transmission rod, with the second fixed rod fixedly connected to the damper.

[0020] The above technical solution is adopted: by setting damping, when the first transmission rod is stretched during use, that is, during the process of the device being lifted, it will drive the second fixed rod to compress the damping.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, the hydraulic telescopic rod is activated to lift the worktable. The second transmission rod rises with the worktable, pulling the third transmission rod to rotate around the second pivot. During the rotation of the third transmission rod, the first transmission rod is pulled to slide within the sliding groove of the fixed frame. Simultaneously, a flexible steel wire rope is used to pull the shielding plate out of the storage compartment, effectively dealing with tools falling from a height with initial horizontal velocity. Compared to traditional fixed guard plates, the protection range is more comprehensive. In addition, the placement frame is equipped with a mechanical telescopic rod, a fifth transmission rod, a sixth transmission rod, and a damping structure. During lifting and lowering, the mechanical telescopic rod is actuated by the third transmission rod, causing the fifth and sixth transmission rods to move. This compresses the damping on the placement frame with the second fixed rod, preventing displacement of the placement frame, ensuring tool stability, reducing the risk of falling, and solving the problem of tools easily falling off in the prior art.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1-4 As shown, this utility model provides a technical solution: a lifting mechanism for building construction, comprising:

[0034] Fixed frame 1, with fasteners 22 fixedly connected to fixed frame 1;

[0035] Transmission assembly 2 is placed on fixed frame 1. Transmission assembly 2 includes a first rotating shaft 23 rotatably connected to fixed frame 1, a lifting rod 21 rotatably connected to the first rotating shaft 23, a worktable 4 slidably connected to the lifting rod 21, a second transmission rod 26 fixedly connected to the worktable 4, a third transmission rod 27 rotatably connected to the second transmission rod 26, a third transmission rod 27 slidably connected to the third transmission rod 27, and a fourth transmission rod 28 rotatably connected to the end of the third transmission rod 27 away from the first transmission rod 25. The fourth transmission rod 28 is fixedly connected to fixed frame 1.

[0036] A mechanical telescopic rod 41 is fixedly connected to the third transmission rod 27. A third rotating shaft 42 is rotatably connected to the mechanical telescopic rod 41. A fifth transmission rod 43 is rotatably connected to the third rotating shaft 42. A sixth transmission rod 45 is fixedly connected to the fifth transmission rod 43. A first fixed rod 46 is rotatably connected to the sixth transmission rod 45. A second fixed rod 47 is fixedly connected to the first fixed rod 46. A placement frame is slidably connected to the second fixed rod 47. A guardrail 44 is fixedly connected to the workbench 4.

[0037] In this invention, the hydraulic telescopic rod is activated to lift the worktable 4. The second transmission rod 26 rises with the worktable 4, pulling the third transmission rod 27 to rotate around the second rotating shaft 3. During the rotation of the third transmission rod 27, the first transmission rod 25 is pulled to slide in the sliding groove of the fixed frame 1. At the same time, the flexible steel wire rope 211 pulls the shield 210 out of the storage compartment 24, thus effectively dealing with tools falling from a height with a horizontal initial velocity. Compared with traditional fixed guard plates, the protection range is more comprehensive. In addition, the placement frame is equipped with a mechanical telescopic rod 41, a fifth transmission rod 43, a sixth transmission rod 45, and a damping structure. During lifting and lowering, the mechanical telescopic rod 41 is moved by the third transmission rod 27, which drives the fifth transmission rod 43 and the sixth transmission rod 45 to move, causing the second fixed rod 47 to compress the damping on the placement frame, preventing the placement frame from shifting, ensuring the stability of the tool, reducing the risk of falling, and solving the problem of tools easily falling off in the prior art.

[0038] Furthermore, such as Figures 1 to 4 As shown, the second transmission rod 26 is rotatably connected to the third transmission rod 27 via the fourth rotating shaft 31. Both ends of the third transmission rod 27 are rotatably connected to the fourth rotating shaft 31. The end of the third transmission rod 27 away from the second transmission rod 26 is rotatably connected to the fourth transmission rod 28 via the fourth rotating shaft 31. In use, when the third transmission rod 27 is driven to move, it will pull or push out the first transmission rod 25, thereby realizing the transmission of the first transmission rod 25.

[0039] A sliding groove is provided on the fixed frame 1, and the first transmission rod 25 is slidably connected in the sliding groove on the fixed frame 1. By providing a sliding groove on the fixed frame 1, the sliding of the first transmission rod 25 is guided during use.

[0040] A fixed compartment 29 is fixedly connected to the fixed frame 1, and a second rotating shaft 3 is rotatably connected to the fixed compartment 29. A third transmission rod 27 is rotatably connected to the second rotating shaft 3. By fixing the fixed compartment 29 to the fixed frame 1, it is convenient to rotate the third transmission rod 27 during use.

[0041] A storage compartment 24 is fixedly connected to the fixed frame 1. A flexible steel wire rope 211 is fixedly connected inside the storage compartment 24. A baffle plate 210 is fixedly connected to the flexible steel wire rope 211. The end of the flexible steel wire rope 211 away from the storage compartment 24 is fixedly connected to the first transmission rod 25. By fixing the storage compartment 24 to the fixed frame 1, it is convenient to connect the baffle plate 210 when in use. After the baffle plate 210 is pulled out, it can protect the internal components of the fixed frame 1.

[0042] The fixed chamber 29 has an opening, and the baffle plate 210 and the flexible steel wire rope 211 are slidably connected in the opening on the fixed chamber 29. By having an opening on the fixed chamber 29, the baffle plate 210 and the flexible steel wire rope 211 are prevented from being blocked during use.

[0043] The above solution also fails to address how to secure the placement frame, such as... Figures 1 to 4 As shown, the placement frame on the third transmission rod 27 is fixedly connected to the workbench 4. A damper is fixedly connected to the placement frame on the third transmission rod 27. The second fixed rod 47 is fixedly connected to the damper. By setting the damper, when the first transmission rod 25 is stretched during use, that is, during the process of the device being lifted, the second fixed rod 47 will be driven to compress the damper.

[0044] The working principle provided by this utility model is as follows: Figures 1 to 4 As shown:

[0045] During installation, first use the fixing piece 22 to install the hydraulic telescopic rod, and fix the output end of the hydraulic telescopic rod to the bottom of the workbench 4;

[0046] When in use, the hydraulic telescopic rod is activated, which raises the workbench 4. At this time, the third transmission rod 27 is pulled up by the second transmission rod 26, which pushes out the first transmission rod 25 by the third transmission rod 27, which gradually moves to a horizontal state. The flexible steel wire rope 211 is used to pull the cover plate 210 out of the storage compartment 24, so that the cover plate 210 covers the fixed frame 1.

[0047] Subsequently, as the third transmission rod 27 rotates on the second rotating shaft 3, the mechanical telescopic rod 41 will be moved to slide on the worktable 4, causing the fifth transmission rod 43 to drive the sixth transmission rod 45 and the second fixed rod 47 to compress the damping on the placement frame, preventing the placement frame from shifting and making it difficult for the tools inside the placement frame to fall off.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
