Description

Technical Field

[0001] This utility model relates to the field of construction engineering technology, specifically to a material handling trolley for construction engineering. Background Technology

[0002] In the construction industry, traditional material transportation typically involves manual labor or a combination of manual labor and handcarts for loading and pushing. When there is a large amount of material, it is necessary to transport it back and forth, which is not only inefficient and requires multiple workers to work together, but also greatly increases the labor intensity of the workers. With the advancement of technology, some small materials are transported using intelligent transport vehicles or transport robots. With pre-set routes, the intelligent transport vehicles or transport robots automatically transport materials over short distances under the control of control programs, such as transportation within the construction site. Workers only need to load and unload, which greatly improves work efficiency.

[0003] However, this type of intelligent transportation equipment also has certain drawbacks: when debris blocks the road, the chassis of the transport vehicle or robot is low, and once the wheels run over the debris, it may tilt, and in severe cases, it may tip over, posing a certain safety hazard; since it is designed for smaller debris such as stones or cement fragments, it is more likely to cause the transportation equipment to tip over or fall over, because large debris will not enter under the chassis or wheels of the intelligent transportation equipment, but will directly block the passage of the transportation equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a material handling trolley for construction projects, which can remove debris in the travel route to ensure normal movement, avoid tilting or tipping, and ensure stable material transfer.

[0005] To achieve the aforementioned technical effects, this utility model provides a material handling trolley for construction engineering, comprising a transport vehicle body with four wheels. A power unit is installed inside the transport vehicle body to drive the four wheels. A holding platform is fixedly connected to the top surface of the transport vehicle body. The trolley includes a debris removal device, which comprises a mounting frame fixedly connected to the bottom surface of the transport vehicle body. Along the forward direction of the transport vehicle body, the mounting frame is located at the front end of the transport vehicle body. A pushing mechanism is provided within the mounting frame, comprising a removal plate, a fixed shaft, and a mounting plate. The system comprises a hydraulic rod and a sliding block. The deflector plate has a first waist-shaped groove, which is located at the front of the deflector plate along its length. A rectangular hole is provided on the front side wall of the mounting frame. A fixed shaft is vertically fixedly connected to the center of the rectangular hole. The width of the rectangular hole is greater than the thickness of the deflector plate. The deflector plate is oscillatingly connected within the rectangular hole. The first waist-shaped groove is slidably sleeved on the outside of the fixed shaft. The mounting plate is fixedly connected inside the mounting frame. The rear end of the hydraulic rod is fixedly connected to the mounting plate. The rear end of the sliding block is rotatably connected to the front end of the hydraulic rod piston rod via a rotating shaft. The front end of the sliding block is connected to the rear of the deflector plate.

[0006] Furthermore, the pushing mechanism includes limit posts. Limit posts are fixedly connected to the left and right sides of the front end of the sliding block. The two limit posts are symmetrical about the center of the sliding block. A second waist-shaped groove is provided at the rear of the deflection plate. The second waist-shaped groove is set along the length direction of the deflection plate. Both limit posts are slidably connected in the second waist-shaped groove.

[0007] Furthermore, the pushing mechanism includes a guide frame, which is fixedly connected inside the mounting frame. The guide frame is provided with a guide groove, which is set along the length of the guide frame. A sliding column is fixedly connected to the rear end of the drive plate, and the sliding column is slidably connected in the guide groove.

[0008] Furthermore, the guide frame is arc-shaped, and the guide groove is arc-shaped.

[0009] Furthermore, the pushing mechanism includes a motor, a threaded shaft, a threaded sleeve, and a guide block. The motor is fixedly connected inside the mounting frame, the threaded shaft is fixedly connected to the motor output shaft, the front end of the threaded sleeve is fixedly connected to the rear side of the guide frame, the rear end of the threaded sleeve has a threaded hole, the threaded hole at the rear end of the threaded sleeve is connected to the threaded shaft, the guide block is fixedly connected to the side wall of the threaded sleeve, and the inner wall of the mounting frame has a sliding groove, the guide block is slidably connected in the sliding groove of the inner wall of the mounting frame.

[0010] Furthermore, protective frames are fixedly connected to the four corners of the top surface of the holding platform.

[0011] Furthermore, the horizontal cross-sectional shape of the protective frame is "L" shaped, and the inner sides of the "L" shapes of the four protective frames all face the center of the holding platform.

[0012] The beneficial effects of this utility model are:

[0013] In use, materials can be placed on a holding platform. When the transport vehicle is moving, the hydraulic rod is activated to drive the sliding block to slide on the outside of the deflector plate. This causes the deflector plate to swing around a fixed axis, ensuring that debris on the road surface is removed, allowing the transport vehicle to move normally, preventing it from tilting or tipping over, and ensuring stable transport of materials.

[0014] By starting the motor to drive the threaded shaft to move, the threaded shaft drives the threaded sleeve to move, the threaded sleeve drives the guide frame to move, which in turn drives the deflector plate to move. At this time, the extension amount of the deflector plate can be controlled. When it is not in use, it can be retracted, which greatly avoids the space occupied by the deflector plate extending out.

[0015] The guide groove on the inner side of its guide frame can ensure the swing range of the deflector plate and ensure that the deflector plate can be used normally. Attached Figure Description

[0020] like Figures 1-3 As shown, this utility model discloses a material handling trolley for construction engineering, comprising a transport vehicle body 1, which includes four wheels 4. A power unit is installed inside the transport vehicle body 1, driving the four wheels 4. The power unit typically includes a variable frequency motor and a storage battery pack, which is smaller and easier to maintain than a gasoline generator. The variable frequency motor also requires mechanical transmission components such as drive gears and drive chains to drive the four wheels 4. The use of the variable frequency motor, storage battery pack, and mechanical transmission components are all conventional techniques in this field and will not be described in detail here. A holding platform 2 is fixedly connected to the top surface of the transport vehicle body 1. The materials to be transferred are placed on the top surface of the holding platform 2. A debris removal device 5 is included, comprising a mounting frame 501 fixedly connected to the bottom surface of the transport vehicle body 1. Along the forward direction of the transport vehicle body 1, the mounting frame 501 is positioned... At the front end of the transport vehicle body 1, a pushing mechanism is provided in the mounting frame 501. The pushing mechanism includes a drive plate 508, a fixed shaft 509, a mounting plate 511, a hydraulic rod 512, and a sliding block 513. The drive plate 508 is provided with a first waist-shaped groove 510, which is located at the front of the drive plate 508 along its length. A rectangular hole is provided on the front side wall of the mounting frame 501. The fixed shaft 509 is vertically fixedly connected to the center of the rectangular hole. The width of the rectangular hole is greater than the thickness of the drive plate 508. The drive plate 508 is swayed and connected to the rectangular hole. The first waist-shaped groove 510 is slidably sleeved on the outside of the fixed shaft 509. The mounting plate 511 is fixedly connected to the inside of the mounting frame 501. The rear end of the hydraulic rod 512 is fixedly connected to the mounting plate 511. The rear end of the sliding block 513 is rotatably connected to the front end of the piston rod of the hydraulic rod 512 through a rotating shaft. The front end of the sliding block 513 is connected to the rear of the drive plate 508.

[0021] When the piston rod of the hydraulic rod 512 extends or retracts, it can control the deflector plate 508 to swing left and right around the fixed shaft 509, thereby driving away debris in front of the transport vehicle body 1.

[0022] The pushing mechanism includes limit posts 514. Limit posts 514 are fixedly connected to the left and right sides of the front end of the sliding block 513. The two limit posts 514 are symmetrical about the center of the sliding block 513. The rear part of the drive plate 508 is provided with a second waist-shaped groove 515. The second waist-shaped groove 515 is arranged along the length direction of the drive plate 508. The two limit posts 514 are slidably connected in the second waist-shaped groove 515.

[0023] The sliding connection between the limiting post 514 and the second waist-shaped groove 515 makes the swing of the deflector plate 508 about the fixed shaft 509 more flexible and stable, while providing conditions for the extension and retraction of the deflector plate 508.

[0024] Furthermore, the pushing mechanism includes a guide frame 505, which is fixedly connected inside the mounting frame 501. The guide frame 505 is provided with a guide groove 506, which is arranged along the length of the guide frame 505. A sliding column 507 is fixedly connected to the rear end of the drive plate 508, and the sliding column 507 is slidably connected in the guide groove 506. The guide frame 505 is arc-shaped, and the guide groove 506 is arc-shaped.

[0025] The guide groove 506 and the sliding column 507 are configured to limit the swing of the deflector plate 508, and at the same time realize the extension and retraction of the deflector plate 508, thereby improving the deflection effect on the front of the transport vehicle body 1.

[0026] The driving mechanism includes a motor 502, a threaded shaft 503, a threaded sleeve 504, and a guide block 516. The motor 502 is fixedly connected inside the mounting frame 501. The threaded shaft 503 is fixedly connected to the output shaft of the motor 502. The front end of the threaded sleeve 504 is fixedly connected to the rear side of the guide frame 505. The rear end of the threaded sleeve 504 has a threaded hole, which is connected to the threaded shaft 503. The guide block 516 is fixedly connected to the side wall of the threaded sleeve 504. The inner wall of the mounting frame 501 has a sliding groove, and the guide block 516 is slidably connected in the sliding groove of the inner wall of the mounting frame 501.

[0027] The starter motor 502 drives the threaded shaft 503 to move, the threaded shaft 503 drives the threaded sleeve 504 to move, the threaded sleeve 504 drives the guide frame 505 to move, which in turn drives the drive plate 508 to move. At this time, the extension amount of the drive plate 508 can be controlled. When it is not in use, it can be retracted, which greatly avoids the space occupied by the extension of the drive plate 508. The guide block 516 can ensure the stable movement of the threaded sleeve 504 and prevent it from rotating on its own, ensuring that the guide frame 505 can move and adjust its position stably.

[0028] Furthermore, protective frames 3 are fixedly connected to the four corners of the top surface of the holding platform 2.

[0029] Furthermore, the horizontal cross-sectional shape of the protective frame 3 is "L" shaped, and the inner sides of the "L" shapes of the four protective frames 3 all face the center of the holding platform 2.

[0030] The protective frame 3 is designed to prevent materials placed on the top surface of the holding platform 2 from falling off.

[0031] In addition to the technical solutions described above, this utility model can also be equipped with intelligent control components to achieve intelligent control and form an intelligent material handling robot, such as an intelligent controller with a drive motor and hydraulic rod, an intelligent chip for planning the travel route, and a camera for identifying debris.
