Description

Technical Field

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

[0002] In building construction projects, material lifting devices are commonly used vertical transportation equipment. These devices are mainly used to lift building materials such as sand, gravel, cement, bricks, and steel bars from the ground to higher floors or other heights required for construction. Material lifting devices can improve construction efficiency, reduce manual handling, and improve site safety. These types of material lifting devices are generally divided into fixed and mobile types. Fixed devices are generally used to lift heavier materials and are used for long-term purposes, while mobile devices are generally used for short-term purposes and are commonly used to lift lighter materials.

[0003] Currently, fixed building material lifting devices are difficult for workers to load and unload. They also cannot be adjusted in height to suit different building structures, reducing their versatility and adaptability. Furthermore, the devices typically rely on a single steel cable for slinging, which is prone to swaying during lifting, making them unsafe and unstable. This swaying also increases the effort required and leads to greater wear on the steel cable. Therefore, those skilled in the art have provided a building material lifting device to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a building construction material lifting device. This device solves the problems of existing devices being inconvenient for lifting height, transportation, and material swaying during the lifting process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a building construction material lifting device, comprising a support base, a support unit, an electric steel cable winding and unwinding structure, and a material carrying structure.

[0006] The support unit is mounted on the support base. The support unit includes multiple sets of support frames stacked on top of each other and a top cover. The top cover is located at the top of the support unit. There are interlocking snap-fit ​​structures between adjacent sets of support frames. Fasteners pass through the snap-fit ​​structures to make the multiple sets of support frames detachably connected and stably connected.

[0007] Each set of support frames includes two symmetrically arranged support frame components with a gap between them. The gaps between multiple sets of support frames constitute the movable space of the material bearing structure.

[0008] The inner wall of the support frame assembly is provided with a longitudinally continuous slide rail, and the slide rails of adjacent support frame assemblies are located on the same straight line.

[0009] The material carrying structure includes a material hopper and a steel cable connector. Auxiliary pulleys corresponding to the slide rails are provided on both sides of the material hopper.

[0010] The electric steel cable winding and unwinding structure is installed on the support base, located on one side of the support unit. The top cover is equipped with a fixed pulley. The steel cable of the electric steel cable winding and unwinding structure passes through the fixed pulley and is connected to the material carrying structure through the steel cable connector. The electric steel cable winding and unwinding structure is used to drive the material carrying structure to move up and down in the moving space of the material carrying structure.

[0011] Through the above technical solutions, the stackable support frame is easy to assemble and disassemble, and can be stacked at different heights to suit different usage environments. The stackable support frame structure is stable and can ensure safe use. The material carrying structure is driven up and down by an electric steel cable winding structure, which ensures safe and stable lifting of materials without shaking. In addition, the pulley assistance makes it more labor-saving.

[0012] Furthermore, the material hopper is equipped with a hopper gate for unloading.

[0013] Through the above technical solution, the material hopper is equipped with a hopper gate to facilitate unloading.

[0014] Furthermore, the support frame assembly protrudes outward in the longitudinal direction, that is, the cross-section has a "<" or "(" structure;

[0015] The above technical solutions result in higher structural strength and a longer service life for the support frame components.

[0016] Furthermore, the electric steel cable winding and unwinding structure includes a cable winding and unwinding frame, a first fixed pulley and a second fixed pulley. A lifting steel cable is provided on the cable winding and unwinding frame. The first fixed pulley is fixedly installed at the center of one side of the top cover, and the second fixed pulley is fixedly installed at the center of the lower end face of the top cover. One end of the lifting steel cable passes through the first fixed pulley and the second fixed pulley in sequence and is connected to the steel cable connector.

[0017] Furthermore, connecting plates are fixedly connected to the outer sides of both the upper and lower ends of the support frame assembly. Upper connecting buckles are fixedly installed on the front and rear sides of the top of the connecting plate on the upper side of the support frame assembly, and lower connecting buckles are fixedly installed on the front and rear sides of the bottom of the connecting plate on the lower side of the support frame assembly. The upper and lower adjacent support frame assemblies are locked in place by corresponding snap-fitting of the upper and lower connecting buckles, and are fixedly connected by bolts that pass through the upper and lower connecting buckles.

[0018] Furthermore, the support base is provided with a snap-fit ​​seat corresponding to the lower connecting buckle;

[0019] The top cover is provided with a snap-fit ​​platform corresponding to the upper connecting buckle.

[0020] The above technical solution facilitates the assembly and disassembly of the overall structure, and makes the overall connection more stable and secure.

[0021] Furthermore, the top of the side wall of the support frame assembly is provided with a semi-circular groove for passing a lifting steel cable.

[0022] The building material lifting device provided by this utility model has the following beneficial effects:

[0023] 1. This utility model discloses a building material lifting device, in which a support unit serves as the main frame and an electric steel cable retraction structure serves as the driving structure, thereby lifting and lowering the material-bearing structure within the activity space. The support unit comprises multiple stacked support frames. When used in building material lifting devices, the height of the stackable support frames can be adjusted according to the environment. For high-rise buildings, the height of the stackable support frames can be increased by increasing the number of support frame components; for low-rise buildings, the number of support frame components can be reduced accordingly, thus adapting to buildings of different heights. Furthermore, adjacent groups of support frames are connected and reinforced by a snap-fit ​​structure and fasteners, ensuring stable operation of the stackable support frames and facilitating easy assembly and disassembly. The device is safe and convenient to use.

[0024] 2. In this utility model, the inner wall of the support frame assembly is provided with a longitudinally penetrating slide rail, and the slide rails of adjacent support frame assemblies are located on the same straight line. This facilitates the cooperation between the slide rail and the auxiliary pulley of the material carrying structure, enabling the material carrying structure to rise and fall along the slide rail, reducing swaying during material lifting, improving the safety of material lifting, and making the material lifting process smoother and less strenuous.

[0034] 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.

[0035] Reference Figure 1-3 One embodiment of this utility model is a building construction material lifting device, which includes a support base 1, a support unit, an electric steel cable winding and unwinding structure 4, and a material bearing structure 5.

[0036] The support base 1 is used to support the entire device. It is flat and has a support unit at the upper end.

[0037] The support unit includes multiple sets of support frames 2 stacked on top of each other and a top cover 3. Each set of support frames 2 includes two symmetrically arranged support frame components 201 with a gap between them. The gap between the multiple sets of support frames 2 constitutes the movable space of the material bearing structure 5. The top cover is located at the top of the support unit.

[0038] Adjacent support frames 2 are provided with interlocking snap-fit ​​structures, through which fasteners pass to enable detachable and stable connection between multiple support frames 2. The inner wall of each support frame assembly 201 is provided with a longitudinally penetrating slide rail 205, and the slide rails 205 of adjacent support frame assemblies 201 are located on the same straight line.

[0039] The material carrying structure 5 includes a material hopper 501 and a steel cable connector 502. Both sides of the material hopper 501 are provided with auxiliary pulleys 503 corresponding to the slide rail 205.

[0040] The electric steel cable winding and unwinding structure 4 is installed on the support base 1 and located on one side of the support unit. The top cover is provided with a fixed pulley. The steel cable of the electric steel cable winding and unwinding structure 4 passes through the fixed pulley and is connected to the material carrying structure 5 through the steel cable connector 502. The electric steel cable winding and unwinding structure 4 is used to drive the material carrying structure 5 to move up and down in the activity space of the material carrying structure 5.

[0041] Specifically, connecting plates 202 are fixedly connected to the outer sides of both the upper and lower ends of the support frame assembly 201. The connecting plates 202 are integrally connected to the support frame assembly 201. Upper connecting buckles 203 are fixedly installed on the front and rear sides of the top of the connecting plate 202 on the upper side of the support frame assembly 201, and lower connecting buckles 204 are fixedly installed on the front and rear sides of the bottom of the connecting plate 202 on the lower side of the support frame assembly 201. The upper connecting buckles 203 and the lower connecting buckles 204 cooperate with each other, and the upper and lower adjacent support frame assemblies 201 are correspondingly engaged by the upper connecting buckles 203 and the lower connecting buckles 204. The limit is fixed by bolts passing through the upper connecting buckle 203 and the lower connecting buckle 204. The connecting plate 201 and the upper connecting buckle 203 and the lower connecting buckle 204 are all provided with screw holes. The inner side wall of the support frame assembly 201 is provided with two vertical and parallel slide rails 205. The slide rails 205 of the upper and lower adjacent support frame assemblies 201 can achieve seamless docking. The support frame assembly 201 is made of high-strength steel and protrudes outward in the longitudinal direction, that is, the cross-section is in the shape of "<" or "(", which makes the support frame assembly structural strength higher and the service life longer.

[0042] As an example, the material carrying structure 5 includes a material hopper 501, a steel cable connector 502, and several fixing buckles 504 set on the upper ends of both sides of the material hopper 501. The steel cable connector 502 is arranged in a herringbone shape, and its bottom end is fixed to the fixing buckle 504. Both sides of the material hopper 501 are provided with auxiliary pulleys 503 corresponding to the slide rail 205. The material hopper 501 can slide up and down between the stackable support frames 2 on both sides through the auxiliary pulleys 503, which improves the stability of the track and makes the lifting smoother.

[0043] Both the support base 1 and the top cover 3 are equipped with snap-fit ​​structures corresponding to the upper connecting buckle 203 and the lower connecting buckle 204, which facilitates the assembly and disassembly of the support unit with the support base 1 and the top cover 3, and makes the connection more stable.

[0044] The electric steel cable winding and unwinding structure 4 includes a cable winding and unwinding frame 401, a first fixed pulley 403, and a second fixed pulley 404. A lifting steel cable 402 is installed on the cable winding and unwinding frame 401. The cable winding and unwinding frame 401 is driven by a motor. The first fixed pulley 403 is fixedly installed at the center of one side of the top cover 3, and the second fixed pulley 404 is fixedly installed at the center of the lower end face of the top cover 3. One end of the lifting steel cable 402 passes through the first fixed pulley 403 and the second fixed pulley 404 in sequence and is connected to the steel cable connector 502. A semi-circular groove 206 for the lifting steel cable 402 to pass through is opened at the top of the side wall of the support frame assembly 201. The lifting steel cable 402 on the cable winding and unwinding frame 401 is extended and retracted by the motor, which drives the material hopper 501 to slide up and down in the movable space of the material bearing structure 5.

[0045] The material hopper 501 is designed as a box shape with an open top, and a hopper door is provided on the front side of the material hopper 501 to facilitate loading and unloading of materials.

[0046] As an example, the hopper gate is hinged to the bottom of the material hopper 501 and can be flipped outwards. Material baskets for holding materials are placed inside the material hopper 501. Pull rings are installed on the side walls of the material baskets, allowing them to be removed through the hopper gate. During unloading, the hopper gate opens and overlaps the construction platform, serving as a connecting plate between the material hopper 501 and the construction platform. Construction workers can pull the pull rings on the material baskets to move them from the material hopper to the construction platform, facilitating material retrieval and improving safety.

[0047] The number of support frames 2 in the support unit is not limited to two sets. The number can be set according to the usage environment to achieve the corresponding height.

[0048] Working principle: When using the building construction material lifting device, the support frame 2 of the corresponding height is set according to the usage environment. Then the device is assembled. When lifting materials, the materials are loaded into the material hopper 501. The lifting steel cable 402 on the cable retractor 401 is extended and retracted by the motor, which causes the material hopper 501 to slide up and down between the stackable support frames 2 on both sides. The material hopper 501 remains vertical and will not shake, ensuring stability and safety and reducing the possibility of material spillage.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
