Description

Technical Field

Since the equipment needs to load and unload materials periodically instead of continuously transporting them, this may lead to a decrease in the efficiency of the overall production process. Especially when high-speed continuous production is required, this non-continuous feeding method may not meet production needs, limiting its scope of application. Utility Model Content

DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 5 , a material lifting device for construction engineering, comprising a feeding mechanism 1 and a lifting mechanism 2 arranged thereunder, and a buffer mechanism 3 is further connected between the feeding mechanism 1 and the lifting mechanism 2:

[0024] Furthermore, the feeding mechanism 1 includes a mounting plate 101, and a mounting frame 102 is fixedly connected to the front and rear sides of the top of the mounting plate 101, and a plurality of conveying rollers 103 are rotatably connected to the opposite side of the mounting frame 102. A first motor 104 that drives the plurality of conveying rollers 103 to rotate is fixedly connected to one side of the mounting frame 102, and the surfaces of the plurality of conveying rollers 103 are transmission-connected to the same conveyor belt 105, and a plurality of baffles 106 are equidistantly connected to the surface of the conveyor belt 105.

[0025] The mounting plate 101 serves as the basic supporting component of the entire feeding mechanism 1 to ensure stable installation of other components. The mounting frame 102 is fixed on the top of the mounting plate 101. Through its structural design, it supports the arrangement of the conveying rollers 103 to realize the lateral and longitudinal conveying of materials. The first motor 104 directly drives the conveying rollers 103 to rotate. Multiple conveying rollers 103 are installed on the mounting frame 102 and can rotate. They are in contact with the conveyor belt 105 to drive the conveyor belt 105 to move, thereby conveying materials. The designed lifting mechanism 2 is used to change the height of the feeding mechanism 1 and even the entire material lifting equipment to meet the material conveying requirements of different floors or heights. The buffer mechanism 3 is connected between the feeding mechanism 1 and the lifting mechanism 2. Its function is to absorb impact force and vibration during the lifting or lowering of materials to protect the equipment from damage, while ensuring that the material conveying is more stable and reduces damage. Through the integrated feeding, lifting and buffering design, this equipment realizes efficient and safe transmission of materials at the construction site, and is particularly suitable for the vertical or inclined conveying requirements of a large number of building materials in high-rise building construction.

[0026] Furthermore, the lifting mechanism 2 includes a fixed plate 201 arranged below the mounting plate 101, and vertical plates 202 are fixedly connected to the left and right sides of the top of the fixed plate 201, and a bidirectional threaded rod 203 is rotatably connected to the center of the opposite side of the vertical plate 202, and one end of the bidirectional threaded rod 203 is fixedly connected to a second motor 204, and the second motor 204 is fixedly arranged on one side of the vertical plate 202.

[0027] The fixed plate 201 is located below the mounting plate 101, providing a solid foundation for the entire lifting mechanism 2. The vertical plate 202 is fixed on both sides of the top of the fixed plate 201, forming a vertical support frame for the lifting mechanism 2. The bidirectional threaded rod 203 is one of the core components. Through the different thread designs at both ends, one end is left-handed and the other end is right-handed, and the lifting direction can be controlled according to the forward and reverse rotation of the second motor 204.

[0028] Furthermore, both left and right sides of the bidirectional threaded rod 203 are threadedly connected with threaded sleeves 205 , and the inner wall of the threaded sleeve 205 is slidably connected with a limit rod 206 , which is fixedly arranged on the opposite side of the vertical plate 202 .

[0029] The internal and external threads of the threaded sleeve 205 cooperate with the bidirectional threaded rod 203, so that when the bidirectional threaded rod 203 rotates, the threaded sleeve 205 moves axially, and the limit rod 206 is connected to the inner wall of the threaded sleeve 205 by sliding, which plays a role in limiting the movement range of the threaded sleeve 205, and may also participate in transmitting torque to maintain the stability of the system.

[0030] Furthermore, the top of the threaded sleeve 205 is rotatably connected to an inclined electric push rod 207 , and the telescopic end of the electric push rod 207 is rotatably connected to the mounting plate 101 .

[0031] When the electric push rod 207 is working, it can not only push the mounting plate 101 up and down in the vertical direction, but the inclined design may also help to balance the distribution of force, improve the stability and efficiency of the lifting process, and the use of the electric push rod 207 enhances the automation level and control accuracy of the system.

[0032] The lifting mechanism 2 combines the threaded drive and electric push rod 207 technology to achieve accurate and stable lifting of the mounting plate 101 and the feeding mechanism 1 above it. This design not only ensures the lifting capacity, but also ensures the safety and reliability of the material transportation process. It is very suitable for material handling scenarios that require fine control of height changes, such as multi-story construction sites or specific manufacturing production lines.

[0033] Furthermore, the buffer mechanism 3 includes two slide bars 301 equidistantly arranged, the two slide bars 301 are fixedly arranged on the top of the fixed plate 201 , a slide sleeve 302 is slidably connected to the surface of the slide bar 301 , and one end of the slide sleeve 302 is fixedly connected to the rear side of the mounting plate 101 .

[0034] The mechanism utilizes two parallel and equidistantly arranged slide bars 301 as guides, which are firmly mounted on the top of the fixed plate 201 to form a stable support frame. Such a layout ensures that the buffer mechanism 3 can withstand forces from different directions and maintain good directional control.

[0035] Furthermore, a stopper is fixedly connected to the top of the slide rod 301 , and a spring 303 fixedly connected between the fixed plate 201 and the slide sleeve 302 is movably sleeved on the surface of the slide rod 301 .

[0036] The sleeve 302 slides along the slide rod 301, and one end of the sleeve 302 is fixedly connected to the rear side of the mounting plate 101, which means that any movement of the mounting plate 101, such as being pushed or pulled by external forces, will be directly transmitted to the sleeve 302, so that the sleeve 302 slides along the track on the slide rod 301, thereby realizing force transmission and conversion. The presence of the spring 303 enables the sleeve 302 to absorb and store part of the energy when an external force acts on the mounting plate 101, causing the sleeve 302 to compress the spring 303, thereby reducing the impact of direct impact on the fixed plate 201 or the overall structure. When the external force is withdrawn or the direction is changed, the elastic restoring force of the spring 303 pushes the sleeve 302 and the mounting plate 101 back to the initial or new equilibrium position, thereby realizing the functions of buffering and resetting.

[0037] Furthermore, the conveyor belt 105 and the baffle 106 are both made of rubber material.

[0038] The rubber conveyor belt 105 is widely used in various conveying occasions due to its good elasticity, wear resistance and certain tensile strength. The baffle 106 effectively prevents material from overflowing, and at the same time utilizes the elasticity of the rubber itself to absorb impact force and protect the conveying system.

[0039] Furthermore, the surface of the electric push rod 207 is provided with scale lines showing the extension distance.

[0040] The scale lines are directly marked on the housing of the electric linear actuator 207 , and the operator can quickly determine the current extension length of the electric linear actuator 207 without the aid of additional measuring tools, which is conducive to rapid adjustment and positioning on site.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
