Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a material transfer device for building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. It includes foundation construction, main structure construction, roof construction, decoration construction, etc. The place where construction work is carried out is called the "construction site" or "construction site". During the construction process, corresponding construction transfer equipment is often used to transfer and process building materials and construction waste.

[0003] For example, utility model patent CN219668309U discloses a construction waste transfer device, including a main body. The main body includes a transport vehicle body. Support rods are installed at both ends of one side of the bottom of the transport vehicle body. A mounting block is connected to the bottom of the transport vehicle body away from the support rods via a spring shock absorber. Wheels are connected to both sides of the mounting block. A water tank is installed at the bottom of the transport vehicle body, located between the two support rods. A handrail is installed on the side of the transport vehicle body near the support rods. A device that effectively reduces dust is installed on the side of the transport vehicle body near the handrail. The spray system is problematic. When this device is in use, the ground at the construction site contains residual cement, sand, and other pollutants. The conveying device moves across the construction site via wheels. During this movement, the residual cement, sand, and other pollutants adhere to the wheels, increasing the contact area between the wheels and the ground. This increases the friction between the wheels and the ground, increasing the workload for workers. At the same time, the residual cement, sand, and other pollutants make the wheels uneven, which can cause bumps during the movement of the transport device, resulting in building materials scattering from inside the vehicle and causing environmental pollution. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a material transfer device for construction, which solves the problem that when existing transfer devices are used, there are residual cement, sand, and other contaminants on the ground at the construction site. During the movement of the transfer device via wheels, residual cement, sand, and other contaminants adhere to the wheels, increasing the contact area between the wheels and the ground, thereby increasing the friction between the wheels and the ground and increasing the workload of the workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material transfer device for construction, comprising a conveying bin, a support column rotatably mounted on the lower wall of the conveying bin, movable wheels mounted at both ends of the support column, protective shells mounted on both sides of the conveying bin, a scraper rotatably mounted inside the protective shell, the scraper being movably mounted on the movable wheels, a third support block mounted inside the protective shell, a cavity mounted on the third support block, a third spring mounted inside the cavity of the third support block, and a fourth support block mounted on the third spring and located inside the cavity of the third support block, the fourth support block being movably mounted on the scraper.

[0006] Preferably, the protective shell is provided with a second fixing compartment, on which a first fixing compartment is movably disposed.

[0009] Preferably, a pair of support rods are provided on the lower wall of the conveying chamber.

[0010] Beneficial effects

[0011] The construction material transfer device provided by this utility model has the following beneficial effects:

[0012] The elastic force generated by the third spring in this design drives the fourth support block to move, which in turn causes the scraper to press on the moving wheel. When the conveying device moves forward, the moving wheel rotates clockwise, and the scraper can promptly remove the contaminants attached to the moving wheel, avoiding the situation where the contact area between the moving wheel and the ground increases, which would lead to increased friction between the moving wheel and the ground. This reduces the workload of the workers and improves the working efficiency of the transfer device.

[0013] This design lifts the first insert block, drives the first support block to move into the groove, moves the first slot below the first insert block, and inserts the first insert block into the first slot to fix the first support block. This reduces the overall length of the transfer device, makes it easier for staff to store the transfer device, and thus improves the practicality of the transfer device. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a material transfer device for construction, including a conveying bin 9, a support column 6 rotatably arranged on the lower wall of the conveying bin 9, movable wheels 7 respectively arranged at both ends of the support column 6, protective shells 3 respectively arranged on both sides of the conveying bin 9, a scraper 5 rotatably arranged inside the protective shell 3, the scraper 5 being movably arranged on the movable wheels 7, a third support block 25 arranged inside the protective shell 3, a cavity arranged on the third support block 25, a third spring 26 arranged in the cavity of the third support block 25, a fourth support block 27 arranged on the third spring 26 and located in the cavity of the third support block 25, the fourth support block 27 being movably arranged on the scraper 5;

[0022] The third spring 26 is a compression spring. The elastic force generated by the third spring 26 drives the fourth support block 27 to move, thereby causing the scraper 5 to press on the moving wheel 7. When the conveying device moves forward, the moving wheel 7 rotates clockwise. The scraper 5 can remove the contaminants attached to the moving wheel 7 in time, avoiding the situation where the contact area between the walking wheel and the ground increases, which would lead to an increase in the friction between the walking wheel and the ground. This reduces the workload of the workers and improves the working efficiency of the transfer device.

[0023] In this embodiment, the protective shell 3 is further configured such that a second fixing compartment 21 is provided inside the protective shell 3, a first fixing compartment 18 is movably disposed on the second fixing compartment 21, a third slot 20 and a fourth slot 22 are provided inside the second fixing compartment 21, a pull block 17 is movably disposed on the first fixing compartment 18, a second insert block 19 is disposed on the pull block 17, the second insert block 19 is movably disposed in the third slot 20 and the fourth slot 22, a pair of first springs 10 are provided inside the first fixing compartment 18, the first springs 10 are disposed on the second insert block 19, and a first connecting rod 15 is provided on the lower wall surface of the first fixing compartment 18, the first connecting rod 15 is movably disposed on the second fixing compartment 21;

[0024] The drive block 17 moves, causing the second insert block 19 to move away from the third slot 20. The second insert block 19 compresses the first spring 10, and the first spring 10 generates elastic force, driving the first fixing chamber 18 to move, so that the second insert block 19 moves to the position of the fourth slot 22. The drive block 17 is released, and the interaction force generated by the first spring 10 drives the second insert block 19 to move into the fourth slot 22 to fix the first fixing chamber 18.

[0025] In this embodiment, a protective rod 24 is rotatably disposed inside the protective shell 3. One end of the protective rod 24 is movably disposed on the scraper 5, and a cavity is provided on the other end of the protective rod 24. A second spring 23 is disposed inside the cavity of the protective rod 24. A second connecting rod 16 is disposed on the second spring 23 and located inside the cavity of the protective rod 24. The first connecting rod 15 is rotatably disposed on the second connecting rod 16.

[0026] The first fixed chamber 18 is driven to move, the first connecting rod 15 is controlled to move, the second connecting rod 16 is driven to move, the second spring 23 generates elastic force, and the protective rod 24 is driven to rotate, so that one end of the protective rod 24 squeezes the scraper 5, thereby moving the scraper 5 away from the moving wheel 7.

[0027] In this embodiment, a second support block 8 is provided on both sides of the conveying chamber 9 and above the protective shell 3. A groove 14 is provided in each pair of second support blocks 8. A first support block 2 is movably provided in each pair of second support blocks 8. The first support block 2 is slidably disposed in the groove 14. A handle 1 is provided between the pair of first support blocks 2. A first slot 11 and a second slot 13 are provided on the first support block 2. A first insert 12 is provided on the second support block 8. The first insert 12 is movably disposed in the first slot 11 and the second slot 13.

[0028] In this embodiment, a pair of support rods 4 are provided on the lower wall of the conveying chamber 9.

[0029] Example: When storing the transfer device, lift the first insert block 12, drive the first support block 2 to move into the groove 14, and move the first slot 1 below the first insert block 12. Insert the first insert block 12 into the first slot 1 to fix the first support block 2. This reduces the overall length of the transfer device, making it easier for workers to store the transfer device and improving its practicality. When using the transfer device, drive the first support block 2 to move out of the groove 14, and position the second slot 13 below the first insert block 12. Insert the first insert block 12 into the second slot 13 to fix the first support block 2. Drive the pull block 17 to move, causing the second insert block 19 to move, so that the first support block 12 is in place. The second insert 19 moves away from the third slot 20, compressing the first spring 10. The first spring 10 generates elastic force, driving the first fixing chamber 18 to move, causing the second insert 19 to move to the position of the fourth slot 22. Releasing the pull block 17, the interaction force generated by the first spring 10 drives the second insert 19 into the fourth slot 22 to fix the first fixing chamber 18. Driving the first fixing chamber 18 moves the first connecting rod 15, causing the second connecting rod 16 to move. The second spring 23 generates elastic force, causing the protective rod 24 to rotate, causing one end of the protective rod 24 to press against the scraper 5, thereby moving the scraper 5 away from the moving wheel 7 and preventing the moving wheel 7 of the transfer device from reversing. When the clock hand rotates, the scraper 5 gets stuck on the moving wheel 7, causing damage to the moving wheel 7. This improves the service life of the moving wheel 7. When cleaning contaminants from the moving wheel 7, the drive block 17 moves, causing the second insert block 19 to move away from the fourth slot 22. The second insert block 19 compresses the first spring 10, and the first spring 10 generates elastic force, driving the first fixing chamber 18 to move, causing the second insert block 19 to move to the position of the third slot 20. When the pull block 17 is released, the interaction force generated by the first spring 10 drives the second insert block 19 to move into the third slot 20 to fix the first fixing chamber 18. Driving the first fixing chamber 18 to move controls the first... The movement of connecting rod 15 causes the second connecting rod 16 to move. The interaction force generated by the second spring 23 moves the second connecting rod 16 into the cavity of the protective rod 24, causing the protective rod 24 to rotate and move one end of the protective rod 24 away from the scraper 5. The elastic force generated by the third spring 26 causes the fourth support block 27 to move, thereby causing the scraper 5 to press on the moving wheel 7. When the conveying device moves forward, the moving wheel 7 rotates clockwise. The scraper 5 can promptly remove the contaminants attached to the moving wheel 7, avoiding the situation where the contact area between the moving wheel 7 and the ground increases, which would lead to an increase in the friction between the moving wheel 7 and the ground. This reduces the workload of the workers and improves the working efficiency of the transfer device.
