Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a lifting device used for house construction. Background Art

[0002] During the construction of houses, construction workers need to transport a large amount of building materials, equipment and construction equipment from the ground to high places, or accurately position and install them at high places. Traditional transportation methods, such as manual or simple mechanical equipment, are inefficient and unsafe, and cannot meet the high requirements of modern construction for construction efficiency and safety. Therefore, in order to improve construction efficiency and ensure the safety of construction workers and sites, the demand for the use of lifting devices in house construction is growing.

[0003] Lifting devices usually include cranes, hoists, bridge cranes, tower cranes, etc., which can provide efficient and safe handling solutions at construction sites. These devices are connected to the cargo through wire ropes, chains or other forms of slings, and through mechanical devices such as lifting mechanisms, weight-lowering mechanisms and rotating mechanisms, the cargo can be lifted, lowered and rotated to meet different construction needs.

[0004] In house construction, the use of lifting devices can not only reduce manpower input and increase handling speed, but also reduce safety hazards during the construction process and ensure the safety of the construction site.

[0005] However, the existing lifting devices have certain safety hazards when in use. Due to the lack of effective position limiting and anti-rotation function, the objects in the lifting process are easily affected by external forces, causing them to rotate in the air. This rotation not only affects the efficiency of lifting, but also may cause collisions between objects during the lifting process, thereby causing damage. In order to solve this problem, it is necessary to improve the existing lifting devices technically and add position limiting and anti-rotation functions to ensure the safety of the lifting process and the integrity of the objects.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original lifting device. Utility Model Content

[0007] The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a lifting device for house construction that is significantly different from the existing technical solution to solve the problems raised in the above background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lifting device for house construction, comprising a lifting frame, the lifting frame is connected to a mounting frame, and a servo motor is installed on the outer wall of the mounting frame, and the output end of the servo motor is connected to a driving shaft, the end of the driving shaft is rotatably connected to the inner wall of the mounting frame, a first roller frame is installed on the outer wall of the driving shaft, and a steel wire rope is connected to the first roller frame, and a ratchet for locking is installed on the first roller frame, a limiting structure for limiting the ratchet is installed on the mounting frame, one end of the steel wire rope connected to the first roller frame is connected to the end of the lifting frame, and a movable pulley is installed on the steel wire rope, a bearing structure for limiting the position of a plate object is hooked below the movable pulley, a second roller frame is connected to the driving shaft, a limiting chain is wound around the second roller frame, and the end of the limiting chain is connected to the bearing structure, and the limiting chain is connected to a fixed pulley installed on the lifting frame.

[0009] Preferably, the mounting frame is configured as a hollow structure, and a top frame for carrying a counterweight is connected to the top of the mounting frame.

[0010] Preferably, the middle recessed area of ​​the first roller frame is larger than the recessed areas on both sides, and each of the recessed areas on both sides of the first roller frame is connected to a ratchet, and the middle recessed area of ​​the first roller frame is used for winding and connecting the wire rope.

[0011] Preferably, the limiting structure includes a bracket, a limiting rod, and a reset spring. The mounting frame is provided with a bracket, and the end of the bracket passes through the mounting frame and is fitted to the ratchet. A reset spring is connected between the bracket and the mounting frame. A limiting rod is threadedly passed through the bracket, and the end of the limiting rod is fitted to the outer wall of the mounting frame.

[0012] Preferably, the bracket is configured as a "concave" structure, and the contact areas between the two ends of the bracket and the ratchet are configured to be inclined.

[0013] Preferably, the bearing structure includes a corner block, a support rod, a rotating drum, and a fixed rope, each side of the corner block is connected to a support rod, and a rotating drum is threadedly connected between the support rod on each corner block and the support rod on another corner block, and the top of the corner block is connected to a fixed rope, and the fixed ropes are gathered and connected to the movable pulley hook.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: the lifting device used for house construction, through the arrangement of the first roller frame, wire rope, ratchet, limiting structure and movable pulley, makes it possible for the device to pull the lifted objects for transportation and lifting with relatively little effort, thereby reducing the load on the servo motor and the driving shaft caused by the excessive weight of the lifted objects, and the cooperation between the ratchet and the limiting structure does not affect the lifted objects. When the servo motor fails and the objects fall downward under the influence of gravity, causing the driving shaft and the ratchet to reverse, the ratchet is limited by the limiting structure, thereby greatly reducing the occurrence of falling of the lifted objects.

[0015] Through the setting of the bearing structure, it can be flexibly adapted and adjusted according to the lifting plates of different sizes. This design not only facilitates the accurate positioning of plates of various sizes and ensures the safety of the lifting process, but also increases the flexibility of lifting block objects by laying additional bearing plates between the bearing structures. When it is necessary to lift larger or blocky objects, the objects can be placed on the bearing plates, which effectively improves the applicability and safety of the device.

[0016] By setting the second roller frame, the limiting chain and the fixed pulley, the device can limit the bearing structure during the lifting process of the object, prevent it from being affected by external factors, and enhance safety. This design can prevent the bearing structure and the object from rotating and shaking due to strong winds, and is also convenient for lifting and lifting. Such a design not only improves work efficiency, but also ensures the safety of operators. BRIEF DESCRIPTION OF THE DRAWINGS
