Description

Technical Field

[0001] This utility model relates to the field of material lifting technology, and in particular to a material lifting device for building construction. Background Technology

[0002] Currently, with the rapid development of my country's economy and the continuous expansion of construction scale, material lifting equipment is a common type of construction machinery. Workers often need to use material lifting equipment to transport materials from lower to higher places, or vice versa. Its advantages of ease of operation and low cost have led to its increasingly widespread application.

[0003] With the increasing awareness of safety, people have placed higher demands on the safety of material hoists. However, existing material hoists generally have poor safety features, which can easily lead to accidents. Moreover, workers need to move materials into the material hoist and then pull them out when they reach the predetermined height, which is not only time-consuming and labor-intensive but also inefficient. Summary of the Invention

[0004] In view of this, the present invention provides a material lifting device for construction to solve the technical problems mentioned in the background art.

[0005] This utility model solves the above problems through the following technical means:

[0006] The construction material lifting device of this utility model includes a steel frame, a lifting rail on one side of the steel frame, a cargo cage installed on the lifting rail by a brake, a lifting drive structure for driving the cargo cage to move up and down, a pulley on the steel frame for guiding the movement direction of the steel cable of the lifting drive structure, and a conveying component at the bottom of the cargo cage for conveying goods.

[0007] Preferably, the conveying assembly includes at least two drive rollers whose rotation is controlled by a servo motor.

[0008] Preferably, the conveying assembly further includes a plurality of free rollers, and the plurality of free rollers and the plurality of transmission rollers are arranged according to a fixed pattern.

[0009] Preferably, the side wall of the cargo cage parallel to the conveying assembly has a bottom hinge structure, which allows it to be opened downward to form an openable side wall, and the upper end of the openable side wall is fixed to the cargo cage by a latch.

[0010] Preferably, there are two openable sidewalls, and the other two opposite sidewalls are closed sidewalls.

[0011] Preferably, the bottom hinge of the openable sidewall is at the same height as the conveying assembly.

[0012] Preferably, the top mounting plate of the steel frame is equipped with a tilt alarm.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0014] This utility model relates to a material lifting device for construction. A lifting rail is installed on one side of the steel frame. After the cargo cage is installed on the lifting rail, its vertical movement is limited, ensuring smooth up-and-down movement and preventing the transported goods from swaying, thus eliminating safety hazards. The brake can lock the cargo cage in an emergency, preventing it from falling in case of cable breakage or power failure, increasing the device's safety performance. The conveying assembly at the bottom of the cargo cage supports and transports the goods, reducing manual handling and meeting the conveying speed requirements in production and processing, saving manpower.

Detailed Implementation

[0019] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1 As shown: The construction material lifting device described in this embodiment includes a steel frame 1, a lifting rail 2 located on one side of the steel frame 1, a cargo cage 4 installed on the lifting rail 2 via a brake 3, a lifting drive structure 5 for driving the cargo cage 4 to move up and down, a pulley 7 located on the steel frame 1 for guiding the movement direction of the steel cable 6 of the lifting drive structure 5, and a conveying component 8 located at the bottom of the cargo cage 4 for conveying goods.

[0022] The construction material lifting device described in this embodiment has a lifting rail 2 installed on one side of the steel frame 1. After the cargo cage 4 is installed on the lifting rail 2, the vertical movement trajectory of the cargo cage 4 can be limited, allowing it to move smoothly up and down, ensuring that the items to be transported will not shake and eliminating safety hazards. The brake 3 can lock the cargo cage 4 in an emergency, preventing the cargo cage 4 from falling when the steel cable 6 breaks or the equipment malfunctions and loses power, thus increasing the safety performance of the equipment. The conveying component 8 at the bottom of the cargo cage 4 can support and convey the items to be transported, reducing manual handling and thus meeting the conveying speed requirements in production and processing, saving manpower.

[0023] As a preferred embodiment of this example, Figures 2-3 As shown, the conveying assembly 8 includes at least two transmission rollers 82 controlled to rotate by a servo motor 81. More specifically, the conveying assembly 8 also includes multiple free rollers 83. The multiple free rollers 83 and the multiple transmission rollers 82 are arranged according to a fixed pattern. When the item to be transported is placed at the entrance of the cargo cage 4, the servo motor 81 is turned on to drive the transmission rollers 82 to rotate, and then the multiple free rollers 83 are used to convey the item to its position.

[0024] As a preferred embodiment of this example, Figures 2-3As shown, the side wall of the cargo cage 4, which is parallel to the conveying assembly 8, has a bottom hinge structure, allowing it to open downwards to form an openable side wall 41. When the cargo cage 4 is at its lowest position, the openable side wall 41 is opened downwards, with its end overlapping the ground to form a ramp, allowing the cargo transfer vehicle to be easily pushed up for loading and unloading, saving manpower and improving loading and unloading efficiency. The upper end of the openable side wall 41 is fixed to the cargo cage 4 by a latch 42. After loading is completed, the openable side wall 41 is locked upwards to enclose the goods inside the cargo cage 4, preventing the goods from falling from a height and improving safety.

[0025] In a preferred embodiment of this invention, the two openable sidewalls 41 are opposite each other, allowing for selection of the direction of loading and unloading materials as needed, thus having a wider range of applications. The other two opposite sidewalls are closed sidewalls 43.

[0026] In a preferred embodiment of this invention, the bottom hinge of the openable sidewall 41 is at the same height as the conveying assembly 8. When the openable sidewall 41 is opened downwards, the end overlaps the ground, and the hinge is flush with the conveying assembly 8, thereby enabling the conveying assembly 8 and the openable sidewall 41 to form a continuous conveying route and avoiding the situation where the wheels of the cargo transfer vehicle get stuck at the connection.

[0027] As a further preferred embodiment of this example, a tilt alarm 10 is provided on the top mounting plate 9 of the steel frame 1. When the steel frame 1 tilts or sways due to the impact of the overlapping quality of the steel frame 1 or due to severe weather, the tilt alarm 10 detects the angle change and alarms, thereby alerting construction personnel and improving construction safety.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
