Description

Technical Field

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

[0002] Building construction refers to the comprehensive activities of processing, transporting, installing, assembling, and constructing building materials, components, and equipment according to design drawings, construction specifications, and relevant technical standards during the implementation of a building project. It includes not only civil engineering and decoration engineering, but also the implementation of supporting projects such as water and electricity installation, water supply and drainage, HVAC, and fire protection. The building construction process requires the collaboration of various professionals, relying on mechanical equipment and construction techniques to transform architectural design intentions into actual engineering entities. Its core objectives are to ensure the safety, durability, practicality, and aesthetics of buildings, meeting functional and quality requirements, while adhering to environmental protection and energy conservation requirements, and achieving smooth delivery and sustainable use of the building project.

[0003] During construction, specialized conveying equipment is typically required for the efficient transport of tools, building materials, and other items. Currently, most existing construction conveying systems employ a structure where the material conveyor is welded and fixed to a bottom support base. While this fixed structure offers advantages in overall rigidity and load-bearing capacity, the inability to quickly disassemble or adjust the connection means that the conveyor's angle, working height, and position are difficult to adjust flexibly according to construction conditions. This hinders the convenient transport of materials to different heights or work surfaces to meet the ever-changing construction needs on site. Consequently, the equipment suffers from poor adaptability, limited site layout, reduced construction efficiency, and increased reliance on external auxiliary equipment or manual adjustments.

[0004] Based on this, we propose a conveying device for building construction to solve the aforementioned problems. Utility Model Content

[0010] Optionally, the hydraulic lifting mechanism includes a hydraulic control box, which is connected to the top of the mounting base plate. A hydraulic cylinder is connected to the top side of the mounting base plate near the hydraulic control box. The hydraulic cylinder is connected to the hydraulic control box through a hydraulic pipeline. A top shaft is fixedly installed at the top of the piston rod of the hydraulic cylinder, and fixed flanges are connected to both ends of the top shaft through bearings.

[0011] Optionally, the bottom of the material conveyor is connected to several sets of belt rollers via bearings. A drive motor is installed at one end of the material conveyor, and the drive motor is connected to one end of one set of belt rollers. Two sets of hinge plates are installed at the end of the material conveyor near the drive motor.

[0017] 2. The construction conveying device designed in this scheme controls the lifting and lowering movement of the hydraulic cylinder piston rod through a hydraulic control box, which drives the top shaft and mounting base plate to lift and lower as a whole. This allows the support height of the material conveyor to be flexibly adjusted on the construction site. At the same time, in conjunction with the sliding and rotation adjustment of the guide connector and ball screw, the tilt angle of the conveyor can be further fine-tuned, achieving dual optimization of height and tilt angle. This enables the conveying device to adapt to various construction environments and different operational requirements, improves construction accuracy and efficiency, reduces reliance on external auxiliary equipment and manual adjustments, and enhances the stability and safety of the conveying process.

Detailed Implementation

[0023] 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.

[0024] Example 1: Refer to Figures 1 to 5This utility model provides an embodiment of a construction conveying device, including a material conveyor 1. A support adjustment assembly 2 is installed at the bottom of the material conveyor 1. The support adjustment assembly 2 includes a first support component 3, a second support component 4 connected to the middle of the first support component 3, and a guide connector 5 between the second support component 4 and the material conveyor 1. The second support component 4 includes a mounting base 6, and a hydraulic lifting mechanism 7 is provided on the top of the mounting base 6. The first support component 3 includes a support base frame 8, with two sets of hinge seats 9 installed at one end of the support base frame 8. A cross brace 10 is connected to the end of the support base frame 8 near the hinge seats 9, and a motor support plate 11 is provided at the end of the support base frame 8 away from the hinge seats 9. This construction conveying device, through the combination mechanism of the material conveyor 1, the support adjustment assembly 2, the ball screw 12, and the screw nut 15, uses a motor drive 13 to drive the ball screw 12 to rotate, causing the screw nut 15 to move axially along the ball screw 12. The mounting base plate 6 and the material conveyor 1 are slidably adjusted within the first guide groove 14 and the second guide groove 16, allowing for flexible changes in the conveyor's tilt angle. This enables the conveying of materials to different heights or work surfaces according to construction needs. Two sets of ball screws 12 are connected between the motor support plate 11 and the cross brace plate 10 via bearings. A motor drive 13 is mounted on the top of the motor support plate 11, and its output end is connected to the two sets of ball screws 12. By connecting the two sets of ball screws 12 between the motor support plate 11 and the cross brace plate 10 via bearings, and by connecting the motor drive 13 on the top of the motor support plate 11 to the output end of the ball screws 12, the rotational power of the motor can be stably and accurately transmitted to the ball screws 12, causing the screw nut 15 to move axially. This ensures that the material conveyor 1 moves smoothly and controllably when adjusting its angle, achieving efficient conveying of construction tools and building materials to different heights or work surfaces during construction.

[0025] The bottom of the mounting base plate 6 has a first guide groove 14. Screw nuts 15 are installed inside both sides of the mounting base plate 6 near the first guide groove 14. The screw nuts 15 are structurally matched with the ball screw 12, and there is a rolling fit between the screw nuts 15 and the ball screw 12. Second guide grooves 16 are respectively opened at both ends of the mounting base plate 6. The second guide grooves 16 and the first guide groove 14 are structurally matched with the supporting base frame 8, and there is a sliding fit between the second guide grooves 16 and the first guide groove 14 and the supporting base frame 8. Moving wheels 17 are also installed at the four corners of the bottom of the mounting base plate 6 and the supporting base frame 8. Through the rolling fit between the mounting base plate 6 and the screw nuts 15 and the ball screw 12, and the sliding fit between the second guide grooves 16 and the first guide groove 14 and the supporting base frame 8, the mounting base plate 6 can be moved horizontally. The smooth sliding ensures that the material conveyor 1 remains stable, precise, and controllable during tilt angle adjustment. The hydraulic lifting mechanism 7 includes a hydraulic control box 18, which is connected to the top of the mounting base plate 6. A hydraulic cylinder 19 is connected to the top side of the mounting base plate 6 near the hydraulic control box 18. The hydraulic cylinder 19 is connected to the hydraulic control box 18 through a hydraulic pipeline. A top shaft 20 is fixedly installed at the top of the piston rod of the hydraulic cylinder 19. The two ends of the top shaft 20 are also connected to fixed flanges 21 through bearings. Through the coordinated use of the hydraulic control box 18, hydraulic cylinder 19, top shaft 20, and fixed flanges 21, the hydraulic lifting mechanism 7 can flexibly adjust the support height of the material conveyor 1 according to construction needs, realize efficient material transfer between multiple working surfaces, and at the same time ensure the stability and balance of the equipment during the lifting process.

[0026] The bottom of the material conveyor 1 is connected to several sets of belt rollers 22 via bearings. A drive motor 23 is installed at one end of the material conveyor 1, and the drive motor 23 is connected to one end of one set of belt rollers 22. Two sets of hinge plates 24 are installed at the end of the material conveyor 1 near the drive motor 23. The hinge plates 24 and the hinge seats 9 are structurally matched, and the hinge plates 24 and the hinge seats 9 are hinged together. Embedded sliding grooves 25 are also provided on both sides of the bottom of the material conveyor 1. Through the hinged connection structure between the hinge plates 24 and the hinge seats 9, the material conveyor 1 can be reliably hinged to the top of one end of the support base frame 8, so that the first support component 3 and the second support component 4 can flexibly adjust the support angle and height of the conveyor. The guide connector 5 includes a top support plate. 26. Both ends of one side of the top support plate 26 are equipped with embedded sliding strips 27. The embedded sliding strips 27 and the embedded sliding grooves 25 are structurally matched and are in sliding fit. The two ends of the top support plate 26 away from the embedded sliding strips 27 are also connected to fixed side plates 28. The fixed side plates 28 and the fixed flanges 21 are fixedly connected. Through the sliding fit between the embedded sliding strips 27 and the embedded sliding grooves 25 of the guide connector 5, and the fixed connection between the fixed side plates 28 and the fixed flanges 21, the guide connector 5 can be firmly connected to the top shaft 20. At the same time, the guide connector 5 is kept in a movable hinged state at the top of the top shaft 20, so that the guide connector 5 can slide flexibly at its bottom when the support height or tilt angle of the material conveyor 1 is adjusted.

[0027] Reference Figure 6 A comparative embodiment 2, which replaces the embedded slide bar 27, is proposed: the guide connector 5 further includes a transverse support rod 29 arranged laterally on the upper surface of the top support plate 26. Both ends of the transverse support rod 29 are equipped with mating slide bars 30. The mating slide bars 30 are parallel to the opening position of the embedded slide bar 27, and the distance between the embedded slide bar 27 and the mating slide bar 30 is greater than the opening width of the support base frame 8. In the conveying device for construction, the 29 transverse support rod, 30 mating slide bars, and 31 reinforcing member are mainly used to enhance the stability and flexibility of the conveyor. The transverse support rod 29, through the mating slide bars 30 at both ends parallel to the embedded slide groove 27, increases the stability of the support base frame 8 and prevents displacement during sliding. Simultaneously, the distance between the mating slide bars 30 and the embedded slide bar 27 is greater than the width of the support base frame 8, avoiding interference and optimizing the sliding path.

[0028] Reference Figure 7A comparative embodiment 3 with a replaceable embedded slide bar 27 is proposed: the guide connector 5 also includes reinforcing members 31 installed on both sides of the upper end face of the top support plate 26, the upper end face of the reinforcing member 31 being in contact with the bottom end face of the material conveyor 1; the reinforcing member 31 being installed on both sides of the upper end face of the top support plate 26, with its upper end face in contact with the bottom end face of the material conveyor 1, helps to reduce vibration, enhance the stability of the connection, make the conveyor more stable when adjusting the angle and height, and improve the safety and efficiency of construction.

[0029] Working Principle: The construction conveying device designed in this scheme drives the ball screw 12 to rotate through the motor drive 13, causing the screw nut 15 to move axially along the ball screw 12. This causes the mounting base plate 6 to slide within the first guide groove 14 and the second guide groove 16. Simultaneously, the supporting base frame 8 and the guide connector 5 work together to continuously and precisely adjust the tilt angle of the material conveyor 1. During the adjustment process, the moving wheels 17 assist in fine-tuning the overall position of the conveyor, ensuring that its angle relative to the horizontal plane and working surface of the construction site reaches the preset value. This allows construction tools and building materials to be smoothly transported to different heights or multiple working surfaces, while ensuring the stability and continuity of the conveying process, reducing material spillage and the problem of limited space at the construction site, and improving the flexibility of construction layout and overall work efficiency.

[0030] The construction conveying device designed in this scheme controls the piston rod of the hydraulic cylinder 19 and the top shaft 20 to rise and fall axially through the hydraulic control box 18, thereby raising or lowering the mounting base plate 6 as a whole. This allows the support height of the material conveyor 1 to be flexibly adjusted according to construction needs. Through the sliding cooperation of the embedded slide groove 25, the embedded slide bar 27, and the ball screw 12, the tilt angle can also be finely adjusted, so that the height adjustment and the angle adjustment are coordinated to achieve synchronous optimization of height and tilt angle. During the adjustment process, the lifting speed and amplitude are precisely controlled by the hydraulic system to achieve continuous and stable height changes. At the same time, it ensures the stable cooperation between the conveyor and the supporting base frame 8 and the guide connector 5 during the lifting process. This enables efficient material transfer between multiple working surfaces, reduces reliance on manual handling and auxiliary equipment, and improves construction accuracy, efficiency, and safety.

[0031] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
