Description

Technical Field

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

[0002] Construction materials often need to be lifted to high places during construction. Chinese Patent CN207072778U discloses a material lifting device for construction, comprising: a base, a fixed frame at the upper end of the base, an upper plate at the top of the fixed frame, a first lifting motor on one side of the upper end of the upper plate, a second lifting motor on one side of the first lifting motor, and reduction gearboxes on both sides of the first and second lifting motors. The first and second lifting motors are respectively connected to the reduction gearboxes via conical transmission components. This utility model achieves independent fixation of the device through the fixed frame, and a pressure sensor can detect the weight on the support plate to ensure the overall safety of the device. The first and second lifting motors drive the extension and retraction of the pull rope in the reduction gearbox to complete the lifting of the support plate. It consumes less electricity, has strong stability, and is easy to disassemble and install, bringing convenience to the transportation of construction raw materials.

[0003] The aforementioned patent uses a support plate to load building materials during use, but the support plate lacks protective devices, which makes it easy for materials on the support plate to slip during the upward lifting process, causing danger. Therefore, in view of the above situation, there is an urgent need to develop a building material lifting device that is convenient for lifting building materials, has good protection, and prevents building materials from accidentally falling off during the lifting process, so as to overcome the shortcomings in the current practical application and meet the current needs. Utility Model Content

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

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A construction material lifting device includes a frame, a support plate, a lifting mechanism, a limiting rod, and an anti-falling mechanism. The support plate is installed inside the frame, and a lifting lug is fixed to each of the left and right sides of the support plate. A lifting mechanism for moving the lifting lugs and the support plate up and down is installed on the top of the frame. An anti-falling mechanism is installed on both the front and rear sides of the support plate. The anti-falling mechanism includes a guardrail, a rack, a second motor, a gear, a slider, and a slide rail. The guardrail surrounds the outside of the support plate, and a rack is fixed inside the guardrail. The second motor is fixed to the bottom of the support plate, and a gear is fixed to the output shaft of the second motor, meshing with the rack. Two sliders are fixed inside the guardrail, and each slider is slidably mounted on a slide rail, which is fixed to the support plate.

[0007] Preferably, limit baffles are fixed at both the upper and lower ends of the slide rail.

[0008] Preferably, the lifting mechanism includes: a first motor, a drive shaft, a reel, and a wire rope. The first motor is fixed to the top of the frame, the drive shaft is rotatably connected to the top of the frame, the output shaft of the first motor is fixed to the drive shaft, two reels are fixed on the drive shaft, and a wire rope is installed on each reel. The upper end of the wire rope is fixed to the reel, and the lower end is fixed to the lifting lug.

[0009] Preferably, a limiting rod is fixed on each of the left and right sides inside the frame, the limiting rod passes through the lifting lug, and the lifting lug slides in contact with the limiting rod.

[0010] The beneficial effects of this utility model are as follows: When loading construction materials, the protective railing is first lowered to its lowest position, exposing the support plate and preventing it from obstructing the placement of materials. Then, the construction materials are placed on the support plate. After placement, a second motor drives a gear to rotate, which in turn moves a rack upwards, causing the protective railing to rise and block the outer perimeter of the support plate, preventing materials from falling off. Finally, a first motor drives a drive shaft and a pulley to rotate, which in turn retracts the wire rope, causing the lifting lugs and support plate to rise, thus lifting the materials upwards. In summary, this utility model provides convenient lifting of construction materials, offers good protection, and prevents materials from accidentally falling off during the lifting process.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Specific implementation examples are given below.

[0021] See Figures 1-6In this embodiment of the invention, a building material lifting device includes a frame 1, a support plate 2, a lifting mechanism 3, a limiting rod 4, and an anti-falling mechanism 5. The support plate 2 is installed inside the frame 1 and is used to hold building materials. A lifting lug 201 is fixed to each of the left and right sides of the support plate 2. A limiting rod 4 is fixed to each of the left and right sides inside the frame 1. The limiting rod 4 passes through the lifting lug 201, and the lifting lug 201 slides in contact with the limiting rod 4. The limiting rod 4 ensures that the support plate 2 can only move up and down. To prevent swaying and improve stability, a lifting mechanism 3 is installed on the top of the frame 1 to drive the lifting lug 201 and the support plate 2 to move up and down. An anti-falling mechanism 5 is installed on both the front and rear sides of the support plate 2. The anti-falling mechanism 5 includes: a guardrail 501, a rack 502, a second motor 503, a gear 504, a slider 505, and a slide rail 506. The guardrail 501 surrounds the outside of the support plate 2, and the rack 502 is fixed inside the guardrail 501. The second motor 503 is fixed to the support plate 2. At the bottom, a gear 504 is fixed on the output shaft of the second motor 503. The gear 504 meshes with a rack 502. Two sliders 505 are fixed inside the guardrail 501. Each slider 505 is slidably mounted on a slide rail 506. The slide rail 506 is fixed to the support plate 2. Limiting plates 5061 are fixed at both the upper and lower ends of the slide rail 506. The limiting plates 5061 prevent the sliders 505 from falling off the slide rail 506. When loading, the guardrail 501 is first lowered to its lowest position. The support plate 2 is exposed to prevent the guardrail 501 from interfering with the placement of materials on the support plate 2. Then, the second motor 503 drives the gear 504 to rotate, which in turn drives the rack 502 to move upward. The rack 502 then drives the guardrail 501 to move upward, thus blocking the outer perimeter of the support plate 2 and preventing materials from falling off. Finally, the lifting mechanism 3 moves the support plate 2 upward, thereby lifting the materials upward.

[0022] The lifting mechanism 3 includes a first motor 301, a drive shaft 302, a reel 303, and a wire rope 304. The first motor 301 is fixed to the top of the frame 1, and the drive shaft 302 is rotatably connected to the top of the frame 1. The output shaft of the first motor 301 is fixed to the drive shaft 302. Two reels 303 are fixed on the drive shaft 302, and a wire rope 304 is installed on each reel 303. The upper end of the wire rope 304 is fixed to the reel 303, and the lower end is fixed to the lifting lug 201. In use, the first motor 301 drives the drive shaft 302 and the reels 303 to rotate. The rotation of the reels 303 causes the wire rope 304 to retract, and the wire rope 304 causes the lifting lug 201 and the bearing plate 2 to move upward.

[0023] Working principle: When loading construction materials, the protective railing 501 is first lowered to its lowest position, exposing the bearing plate 2. This prevents the protective railing 501 from interfering with the placement of materials on the bearing plate 2. Then, the construction materials are placed on the bearing plate 2. After the materials are in place, the second motor 503 drives the gear 504 to rotate. The rotation of the gear 504 drives the rack 502 to move upward, which in turn drives the protective railing 501 to move upward. This allows the protective railing 501 to block the outer perimeter of the bearing plate 2, preventing materials from falling off. Finally, the first motor 301 drives the drive shaft 302 and the pulley 303 to rotate. The rotation of the pulley 303 causes the wire rope 304 to retract, which in turn drives the lifting lug 201 and the bearing plate 2 to move upward, thereby lifting the materials upward.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
