Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction unloading technology, specifically to an unloading device for building construction. Background Technology
[0002] During construction, materials are typically transported to the construction site using large transport vehicles (such as dump trucks and trailers) or hoisting equipment (such as tower cranes and hoists). These vehicles cannot directly place materials at specific construction locations; therefore, unloading devices act as a transfer platform. Construction sites have limited space, and different construction stages require different types and quantities of materials. Unloading allows for the efficient distribution of materials across different areas of the construction site, facilitating the smooth progress of the construction process.
[0003] For decorative materials such as building stone and tiles, bumps and collisions during transport can cause surface damage or cracks. Using an unloading device to properly place these materials in a safe location can reduce the impact of handling on material quality. Currently, unloading tile materials often involves manually unloading them directly from the transport vehicle or manually pushing a handcart to carefully stack the tile slabs. This manual method easily leads to bumps or scratches on the edges of the tiles, which are only wrapped in cardboard, and there is also a risk of tiles falling and breaking from heights. Therefore, we propose an unloading device for building construction. Utility Model Content

[0006] Two lead screws are rotatably connected to the flatbed cart, and the two lead screws are symmetrically arranged on both sides of the flatbed cart. A bevel gear is fixedly connected to the upper end of each of the two lead screws. A bevel gear rod is arranged above the two bevel gears. The bevel gear rod is composed of two bevel gears and a connecting rod. The two bevel gears of the bevel gear rod are symmetrically arranged, and the bevel gears of the bevel gear rod mesh with the bevel gears fixedly connected to the upper end of the lead screws. A motor is fixedly installed on the flatbed cart. The output shaft of the motor is fixedly connected to one end of the bevel gear rod. Ball bearing boxes are provided on both sides of the protective mechanism. The ball bearing boxes are threadedly connected to the lead screws.
[0007] As a further improvement to this technical solution, the protective mechanism includes a base, on which side plates are fixedly installed on the left, right and rear sides. The side plates are hollow to reduce material usage.
[0008] As a further improvement to this technical solution, the buffer mechanism includes a plurality of springs, the lower end of which is fixedly connected to the top of the base, and the upper end of which is fixedly connected to a rectangular slot. The springs and the rectangular slot are arranged between two square frames.
[0009] As a further improvement to this technical solution, the rolling mechanism includes a round rod, which is fixedly connected to the inner walls of both sides of the rectangular groove. A rotating cylinder is arranged around the outside of the round rod, and a rubber anti-slip layer is provided on the outside of the rotating cylinder. The anti-slip layer is provided with concave and convex textures.
[0010] As a further improvement to this technical solution, a limiting mechanism is provided above the flatbed vehicle. The limiting mechanism is used to restrict the lateral movement of the tiles. The limiting mechanism includes a limiting frame, and two springs are fixedly connected inside both ends of the limiting frame. One end of the spring is fixedly connected to a limiting block, and the end of the limiting block away from the spring is a hemisphere.
[0011] As a further improvement to this technical solution, limit strips are fixedly installed on the outer surfaces of the left and right side plates, and grooves are provided on the inner sides of both ends of the limit frame. The limit strips are used to insert into the grooves to limit the position of the limit frame.
[0012] As a further improvement to this technical solution, small holes are provided on the outer surfaces of the side plate and the base, and the limiting block is inserted into the small hole to limit the position of the limiting frame.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. In this construction unloading device, a round rod is fixedly connected to the inner walls of both sides of a rectangular groove. A rotating cylinder is surrounded by the round rod, which supports the rotating cylinder. The round rod and the long side of the rectangular groove are perpendicular to each other, allowing the tile to slide in from one side directly opposite the frame. An anti-slip layer with textured grooves is provided on the outside of the rotating cylinder. This anti-slip layer is made of rubber and prevents the edges of the tile from being squeezed or bumped by the rigid structure. The rolling mechanism reduces the friction of the tile movement by rolling, and the anti-slip layer prevents the edges of the tile from being bumped or scratched. In addition, the lower end of a spring is fixedly connected to the top of the base, and the upper end of the spring group is fixedly connected to the rectangular groove. The rectangular groove is used to evenly distribute the buffering force of the spring group at different positions. The spring group and the rectangular groove are both located between the two frames. The buffering mechanism can alleviate the impact force caused by moving the tile during the tile placement process, preventing the tile from breaking or being damaged.
[0015] 2. In this construction unloading device, after the tiles are filled into the grid formed by the frame and side plates, the vertical movement of the limiting frame is restricted by the insertion of the limiting block into the small hole on the outside of the side plate. Since the limiting strip is inserted into the groove on both sides of the limiting frame, the horizontal movement of the limiting frame is also restricted. Since one end of the limiting block is a semi-circle and the depth of the small hole is equal to the radius of the hemisphere, the limiting block will give the limiting frame a suitable limiting force under the elastic pressure of the spring. The limiting mechanism can then limit the tiles on the side where the tiles are placed, preventing the tiles from falling off. Attached Figure Description

[0024] Example 1
[0025] Please see Figures 1-4As shown, this embodiment provides a material unloading device for construction, including a flatbed truck 1. A protective mechanism 2 is installed on top of the flatbed truck 1. The protective mechanism 2 includes a base 21 for supporting the tiles. Side plates 22 are fixedly installed on the left, right, and rear sides of the base 21. The side plates 22 are hollow to reduce material usage and thus reduce the weight of the device. Several square frames 3 are also provided on the base 21. The square frames 3 are arranged in parallel array between the side plates 22, and all adjacent square frames 3 are equally spaced. This allows the tile to be placed vertically between the protective mechanism 2 and the adjacent square frames 3, thereby limiting the position of the tile. Several buffer mechanisms 4 are provided on the base 21 and between the adjacent square frames 3. The buffer mechanisms 4 include several springs 41. The springs 41 are used to buffer the pressure generated by the weight of the tiles when the worker places them. The lower end of the springs 41 is fixedly connected to the top of the base 21. A rectangular groove 42 is fixedly connected to the upper end of the spring 41. The rectangular groove 42 is used to evenly distribute the buffering force of the spring 41 at different positions. The spring 41 and the rectangular groove 42 are both set between the two square frames 3. The buffer mechanism 4 is used to buffer the impact force of the tile and prevent the tile from being broken by rigid impact force. The buffer mechanism 4 is equipped with several rolling mechanisms. The rolling mechanism includes a round rod 51, which is fixedly connected to the inner walls of both sides of the rectangular groove 42. A rotating cylinder 52 is set around the outside of the round rod 51. The round rod 51 is used to support the rotating cylinder 52. The long side of the round rod 51 and the rectangular groove 42 are set perpendicularly, so that the tile can slide into the position between the square frames 3 from one side. A rubber anti-slip layer is set on the outside of the rotating cylinder 52. The anti-slip layer is provided with concave and convex textures. The rubber anti-slip layer can prevent the corners of the tile from being squeezed by the rigid structure and being scratched or bumped. The rolling mechanism is used to reduce the friction of the tile translation and protect the corners of the tile.
[0026] Please see Figure 1 As shown, a motor 8 is fixedly installed on the flatbed trolley 1. The motor 8 provides rotational driving force. One end of a bevel gear rod 7 is fixedly connected to the output shaft of the motor 8. The output shaft of the motor 8 can drive the bevel gear rod 7 to rotate. The bevel gear rod 7 consists of two bevel gears and a connecting rod. The two bevel gears of the bevel gear rod 7 are symmetrically arranged. Two lead screws 6 are also rotatably connected to the flatbed trolley 1. The upper ends of the two lead screws 6 are fixedly connected to bevel gears. The bevel gears of the bevel gear rod 7 and the bevel gears fixedly connected to the upper ends of the lead screws 6 mesh with each other. The two lead screws 6 are symmetrically arranged on both sides of the flatbed trolley 1. Through the symmetrically arranged bevel gears and lead screws 6, when the bevel gear rod 7 rotates, the transmission of the meshing bevel gears drives the two lead screws 6 to rotate synchronously and symmetrically. Ball bearing boxes 10 are symmetrically arranged on both sides above the flatbed trolley 1. The ball bearing boxes 10 are threadedly connected to the lead screws 6. The symmetrically arranged ball bearing boxes 10 can be raised and lowered synchronously when the symmetrically arranged lead screws 6 rotate. The ball bearing boxes 10 are fixedly connected to the protective mechanism 2. The ball bearing boxes 10 on both sides can drive the protective mechanism 2 to rise and fall.
[0027] Please see Figure 1 and Figure 4 A limiting mechanism 9 is installed above the flatbed trolley 1 to restrict the lateral movement of the tiles. The limiting mechanism 9 includes a limiting frame 91, which is bracket-shaped. The two ends of the limiting frame 91 slide in contact with the side plates 22 on both sides. Limiting strips 23 are fixedly installed on the outer surfaces of the side plates 22 on both sides. Grooves are provided on the inner sides of the two ends of the limiting frame 91. The limiting strips 23 are inserted into the grooves to limit the limiting frame 91 and prevent it from detaching from the side of the protective mechanism 2. Springs 92 are fixedly connected inside both ends of the limiting frame 91. One end of the springs 92 is fixedly connected to a limiting block 93. Spring 92 is used to apply appropriate elastic pressure to the limiting block 93, so that the limiting block 93 fits tightly against the outer side of the side plate 22. The end of the limiting block 93 away from spring 92 is a hemisphere. Small holes are provided on the outer sides of both the side plate 22 and the base 21. The depth of the small holes is equal to the radius of the hemisphere at one end of the limiting block 93. When the limiting frame 91 is lifted, until the hemisphere of the limiting block 93 is inserted into the small hole under the elastic pressure of spring 92, the limiting frame 91 can be limited to the middle of the tile, thereby limiting the tile on the side where the tile is placed and preventing the tile from falling off from the side where it is placed.
[0028] In this embodiment, the unloading device for construction work involves first moving the flatbed trolley 1 to one side of the tile transport vehicle, starting the motor 8, and rotating the bevel gear rod 7 via the output shaft of the motor 8. This, in turn, drives the lead screws 6 on both sides to rotate synchronously, thereby raising the protective mechanism 2 to a suitable height via the ball bearing box 10. The motor 8 is then turned off. Workers can directly place the tiles between the side plate 22 and the adjacent square frame 3 from one side. The square frame 3 and side plate 22 reduce the time and effort wasted by workers aligning the tiles. During placement, the bottom of the tile contacts the rolling mechanism, which includes a round rod 51 fixedly connected to the inner walls of both sides of the rectangular groove 42. A rotating cylinder 52 surrounds the outside of the round rod 51, supporting it. A rubber anti-slip layer with textured grooves is provided on the outside of the rotating cylinder 52. The rolling mechanism reduces friction as the tiles move by rolling the rotating cylinder 52, and the anti-slip layer prevents the edges of the tiles from being bumped or scratched. The buffer mechanism 4 includes several springs 41. The lower end of each spring 41 is fixedly connected to the top of the base 21, and the upper end of each spring 41 is fixedly connected to a rectangular groove 42. The rectangular groove 42 is used to evenly distribute the buffering force of the springs 41 at different positions. Both the springs 41 and the rectangular groove 42 are positioned between two square frames 3. During the process of placing the tile, the buffer mechanism 4 can compress the springs 41 through the rectangular groove 42 to alleviate the impact force caused by moving the tile, preventing the tile from breaking or being damaged, and filling the tile container. After the grid formed by the frame 3 and the side plate 22 is formed, the limiting frame 91 is lifted from one side of the base 21 until the limiting block 93 is inserted into the small hole on the outside of the side plate 22. The vertical movement of the limiting frame 91 is restricted. Since the limiting strip 23 is inserted into the grooves on both sides of the limiting block 93, the horizontal movement of the limiting frame 91 is also restricted to prevent the tile from falling off. Then the reverse motor 8 is reversed to move the tile down onto the flatbed trolley 1. The flatbed trolley 1 is moved to the unloading position, and the limiting block 93 is moved down onto the flatbed trolley 1 to unload the tile.
