DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a construction material conveying device that is easy to pick up and put, including a base 1, and a walking mechanism is installed at the bottom of the base 1, which can ensure that the device can transport the carried construction materials to a designated location. A conveying frame 2 is arranged above the base 1, and the conveying frame 2 is used to carry the construction materials to be transported. Four limiting grooves 3 are opened inside the conveying frame 2, and an ejection hole 4 is opened in the middle of the conveying frame 2. A spring 5 is arranged between the base 1 and the conveying frame 2, which can not only buffer the conveying frame 2 through the spring 5, but also push the conveying frame 2 upward when the top of the conveying frame 2 is empty. Four slide grooves 6 are opened on the top of the base 1, and a slider 7 is slidably connected inside the slide groove 6. The cross-sections of the slide groove 6 and the slider 7 are both T-shaped, which can effectively prevent the slider 7 from detaching from the inside of the slide groove 6. A movable platform 8 is fixedly connected to the top of the slider 7. The cooperation between the slide groove 6 and the slider 7 ensures that the movable platform 8 can move stably on the top of the base 1.

[0032] Reference Figure 1 and Figure 3, the top of the movable platform 8 is fixedly connected with a fixed rod 9, the top of the fixed rod 9 is fixedly connected with a clamping block 10, the top of the movable platform 8 is fixedly connected with a lower bracket 11 on the side away from the fixed rod 9, and the bottom of the conveying frame 2 is fixedly connected with four upper brackets 12, and a connecting rod 13 is arranged between the upper bracket 12 and the lower bracket 11. When the engineering material is placed on the conveying frame 2, the conveying frame 2 will be pressed downward under the action of gravity, so that the conveying frame 2 moves downward and pushes the connecting rod 13 to move, and then the connecting rod 13 pushes the lower bracket 11 to drive the movable platform 8 to move, and under the action of the slide 6 and the slider 7, the four movable platforms 8 are ensured to approach the center of the base 1 synchronously. As the movable platform 8 moves, the fixed rod 9 and the clamping block 10 on its top will approach the center of the conveying frame 2, and the fixed rod 9 moves along the inside of the limiting groove 3 until the clamping block 10 contacts the outside of the engineering material, clamping and fixing the material on the conveying frame 2, and quickly fixing the material on the device to ensure that the device will not fall during the conveying process. The four corners between the base 1 and the conveying frame 2 are fixedly connected with damping rods 22. The damping rods 22 prevent the conveying frame 2 from falling instantly when it moves down, so that the conveying frame 2 moves down slowly and compresses the spring 5. At the same time, when the conveying frame 2 is lifted up by the spring 5, it can be ensured that the conveying frame 2 is slowly lifted up by the spring 5. A discharge assembly is installed in the middle of the base 1, and the engineering materials on the device can be easily lifted up by the discharge assembly, which is convenient for workers to take or unload the materials by loading and unloading devices. The outer side of the fixed rod 9 is slidably connected to the inside of the limit groove 3, and the bottom of the clamping block 10 is set at the top of the conveying frame 2, so that the fixed rod 9 can drive the clamping block 10 to move with the movement of the movable platform 8, clamping and fixing the engineering materials on the conveying frame 2, and at the same time, the clamping block 10 can resist the top of the conveying frame 2 to prevent the spring 5 from lifting the conveying frame 2 upward, thereby ensuring the stability of the conveying frame 2. One end of the connecting rod 13 is rotatably connected to the inner side of the upper bracket 12, and the other end of the connecting rod 13 is rotatably connected to the inner side of the lower bracket 11. The connecting rod 13 can convert the gravity exerted on the conveying frame 2 into power to push the movable platform 8, and then the material is tightly clamped and fixed by the clamping block 10.

[0033] Reference Figure 2 and Figure 3The unloading assembly includes an ejector rod 14 and a fixed frame 18. The outer periphery of the ejector rod 14 is slidably connected to the middle of the base 1. The top of the ejector rod 14 is fixedly connected to a top block 15. The bottom of the ejector rod 14 is fixedly connected to a fixed disk 16. The outer periphery of the ejector rod 14 is sleeved with a compression spring 17. The top of the fixed frame 18 is fixedly connected to the bottom of the base 1. The inner side of the fixed frame 18 is rotatably connected to a lever 19. A movable arm 20 is provided between the lever 19 and the fixed disk 16. Pressing the pedal 21 hard drives the lever 19 to flip. The lever 19 rotates through the support of the fixed frame 18, and the fixed disk 16 is lifted up by the movable arm 20. When the movable arm 20 drives the fixed disk 16 to move upward, it will gradually shrink toward the inside of the lever 19. Then the fixed plate 16 pushes the ejector rod 14 and the ejector block 15 upward, the ejector rod 14 moves upward to compress the compression spring 17, and the ejector block 15 moves upward to pass through the ejector hole 4 and press on the placement rack at the bottom of the material, and the material is conveniently lifted up by the lever. At this time, under the action of the damping rod 22, it is ensured that the spring 5 will not immediately push the conveyor rack 2 upward to contact the placement plate at the bottom of the material, providing sufficient unloading time.

[0034] Reference Figure 2 and Figure 3 , the two ends of the spring 5 are fixedly connected to the middle between the base 1 and the conveying frame 2, so that the conveying frame 2 will compress the spring 5 when it is subjected to gravity. At the same time, when the device moves, the cooperation between the spring 5 and the damping rod 22 can effectively buffer the vibration received, and ensure that the device itself does not vibrate and shake frequently. The top block 15 is sleeved on the inner side of the spring 5, and the outer periphery of the top block 15 is slidably connected to the inside of the ejection hole 4, so that the top block 15 will pass through the inside of the spring 5 and extend from the inside of the ejection hole 4, and then lift the material placed on the conveying frame 2. The top end of the compression spring 17 is fixedly connected to the bottom of the base 1, and the bottom end of the compression spring 17 is fixedly connected to the top of the fixed plate 16. The compression spring 17 can ensure that the lever 19 can push the fixed plate 16 downward when it is not under force, so as to avoid the top block 15 on the top of the ejection rod 14 from being too high, resulting in the material on the conveying frame 2 being supported by the top block 15 when falling, and the material cannot be clamped. One side of the movable arm 20 is hingedly connected to the edge of the fixed plate 16, and the other side of the movable arm 20 is slidably connected to the inside of the lever 19, so that the lever 19 can drive the fixed plate 16 to move up and down through the movable arm 20 when it is turned over. A pedal 21 is fixedly connected to the side of the lever 19 away from the fixed plate 16, and the pedal 21 allows the user to conveniently use the lever to unload, making the device more convenient when taking materials.

[0035] Working principle: When the engineering material is placed on the conveying frame 2, the conveying frame 2 will be pressed downward under the action of gravity, so that the conveying frame 2 moves downward and pushes the connecting rod 13 to move, and then the connecting rod 13 pushes the lower bracket 11 to drive the movable platform 8 to move. Under the action of the slide 6 and the slider 7, the four movable platforms 8 are ensured to move synchronously toward the center of the base 1. As the movable platform 8 moves, the fixed rod 9 and the clamping block 10 on its top will move toward the center of the conveying frame 2. The fixed rod 9 moves along the inside of the limit groove 3 until the clamping block 10 contacts the outside of the engineering material, clamping the material on the conveying frame 2. And when the conveying frame 2 moves downward under gravity, the damping rod 22 and the spring 5 will be compressed synchronously. The spring 5 can buffer the vibration generated by the device passing through the potholes during the movement. Then, the conveying frame 2 is restricted by the action of the damping rod 22, so that the spring 5 cannot drive the conveying frame 2 to move violently during the reset vibration process, and then the spring 5 quickly remains stationary, effectively ensuring the stability of the material during the transportation process.

[0036] When it is necessary to take out the engineering materials, just step on the pedal 21 to drive the lever 19 to flip. The lever 19 rotates through the support of the fixed frame 18, and the fixed plate 16 is lifted up by the movable arm 20. When the movable arm 20 drives the fixed plate 16 to move up, it will gradually shrink toward the inside of the lever 19. After that, the fixed plate 16 pushes the ejector rod 14 and the ejector block 15 to move up. The ejector rod 14 moves up to compress the compression spring 17, and the ejector block 15 moves up to pass through the ejection hole 4 and press on the placement rack at the bottom of the material. With the help of the lever away, the material can be easily lifted up. When the material is lifted up, the top of the conveying frame 2 does not bear the weight of the material. The compressed spring 5 resets and lifts the conveying frame 2 upward, and slowly moves up under the action of the damping rod 22. At this time, as the conveying frame 2 moves up, it will pull the connecting rod 13 to drive the movable platform 8 to move, and then drive the clamping block 10 to loosen from the outside of the material through the movable platform 8, and then the material can be easily taken out of the device.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
