Technical Field

[0001] This utility model relates to the field of pouring device technology, and in particular to a road construction pouring device. Background Technology

[0002] In modern construction engineering, concrete pump trucks are widely used in the pouring operations of large-scale projects such as high-rise buildings, bridges, and roads. They have the advantages of high conveying efficiency and wide material placement range. However, in complex construction sites, especially in corner areas, narrow spaces, or when replenishing materials locally, the pump truck boom is difficult to position precisely, often requiring manual transfer or secondary handling, which affects construction efficiency and pouring quality.

[0003] However, in actual operation, the material placement range at the end of the boom is limited, especially in narrow spaces, corner areas, or low structures. It is difficult to place the material accurately, often requiring manual pushing of carts or hoisting assistance, which is inefficient and labor-intensive. The discharge port of existing pump trucks is mostly at a fixed angle, which cannot flexibly adjust the discharge direction according to the site terrain or formwork position, easily causing concrete spillage, uneven accumulation, or repeated transfer. At the same time, the discharge height of different pump truck models varies greatly, making it difficult to adapt universal guiding devices. How to achieve accurate, flexible, and efficient concrete placement without relying on manual transfer has become an urgent technical problem to be solved to improve the operating coverage and construction convenience of pump trucks. Summary of the Invention

[0016] 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.

[0017] Please see Figures 1 to 4 This utility model provides a technical solution: A road construction pouring device includes a trolley 1. Universal wheels 3 are rotatably connected to the four corners of the lower end face of the trolley 1. A push handle 2 is fixedly installed on the left end face of the trolley 1. A support plate 4 is fixedly installed on the upper end face of the trolley 1. A rotating shaft 6 is rotatably connected to the end of the support plate 4. A guide tube 5 is provided on the upper side of the trolley 1, and the guide tube 5 is rotatably connected to the rotating shaft 6. One end of the guide tube 5 is connected to a flexible tube 7. A threaded rod 8 is rotatably connected between the push handle 2 and the support plate 4. A threaded sleeve 9 is helically driven on the outer surface of the threaded rod 8. A support member 10 is fixedly installed on the lower end face of the guide tube 5. A connecting rod 11 is rotatably connected between the support member 10 and the threaded sleeve 9.

[0018] A drive wheel 12 is provided on the left side of the push handle 2. One end of the threaded rod 8 is fixedly connected to the drive wheel 12. A handle 13 is eccentrically installed on the left end face of the drive wheel 12.

[0019] Two sets of placement rods 14 are fixedly installed on the right end face of the push handle 2, and a threaded rod 15 is rotatably connected between the two sets of placement rods 14.

[0020] A worm gear 16 is fixedly installed on the left side of the outer surface of threaded rod 18, and a worm wheel 17 is fixedly installed in the middle of the outer surface of threaded rod 2 15. The worm wheel 17 meshes with the worm gear 16, and the thread groove on the outer surface of threaded rod 2 15 is a bidirectional symmetrical thread groove.

[0021] Both sides of the outer surface of threaded rod 15 are helically driven by threaded sleeves 18, and the outer surface of threaded sleeves 18 is rotatably connected to connecting rod 20.

[0022] A support member 21 is fixedly installed on the lower end face of the guide tube 5, and a vertical rod 22 is rotatably connected to the end of the support member 21.

[0023] A top block 19 is fixedly installed at the end of the vertical rod 22, and both sets of connecting rods 20 are rotatably connected to the top block 19.

[0024] Push the trolley 1 to the rear of the pump truck, then pull the flexible pipe 7 to the designated position. At this point, it is necessary to adjust the tilt height of the guide pipe 5. By manually rotating the eccentric handle 13 on the drive wheel 12 at one end of the threaded rod 8, the threaded rod 8 will rotate. The threaded sleeve on the outer surface of the threaded rod 8 will move. The threaded sleeve 9 is rotatably connected to the support member 10 on the guide pipe 5 by a connecting rod. Therefore, when the threaded sleeve moves, it will lift the guide pipe 5 through the connecting rod, so that the guide pipe 5 can adjust its angle around the rotating shaft 6, thereby adjusting the height of one end of the guide pipe 5 to adapt to the height of the pump truck. At the same time, the rotation of the threaded rod 8 synchronously drives the worm gear 16 to rotate. When the worm gear 16 engages with the worm wheel 17 on the threaded rod 15, it drives the threaded rod 15 to rotate. The two sets of threaded sleeves 18 on the outer surface of the threaded rod 15 move towards each other and carry their respective connecting rods 20 to move. The other ends of the two sets of connecting rods 20 are rotatably connected to the top block 19 on the vertical rod 22. The vertical rod 22 is rotatably connected to the support 21 on the guide tube 5. Therefore, the guide tube 5 can be driven to adjust its angle around the rotating shaft 6, thereby adjusting the height of one end of the guide tube 5 and connecting it to the unloading hopper of the pump truck. This completes the installation and use of the system, allowing the pump truck to discharge material for pouring operations.

[0025] However, in actual operation, the placement range of concrete at the end of the boom is limited, especially in narrow spaces, corner areas, or low structures, making precise placement difficult. Manual assistance, such as pushing carts or hoisting materials, is often required, resulting in low efficiency and high labor intensity. Existing pump trucks often have fixed-angle discharge ports, making it impossible to flexibly adjust the discharge direction according to the site terrain or formwork position, easily causing concrete spillage, uneven accumulation, or repeated transfers. Furthermore, different pump truck models have significant differences in discharge height, making it difficult to adapt universal guiding devices. Therefore, achieving precise, flexible, and efficient concrete placement without relying on manual transfer has become a key challenge in improving the operational coverage of pump trucks. The technical problem of improving construction convenience urgently needs to be solved. Therefore, this utility model addresses the operational needs of concrete pump trucks by setting up an adjustable concrete guide trolley 1. The tilt angle of the guide pipe 5 can be manually adjusted according to the discharge port height of different pump truck models, achieving precise guidance and flexible placement of concrete. The trolley 1 can be moved to a designated position as needed to smoothly guide concrete from the pump truck's delivery pipe to the formwork or pouring area, reducing manual intervention and avoiding spillage. It has strong angle adaptability and a wide placement range, significantly improving construction efficiency and operational safety under complex working conditions, and enhancing the overall practicality and on-site adaptability of the pump truck system.

[0026] Working principle: After pushing the trolley 1 to the rear of the pump truck, the flexible pipe 7 is pulled to the designated position. At this time, the tilt height of the guide pipe 5 needs to be adjusted. By manually rotating the eccentric handle 13 on the drive wheel 12 at one end of the threaded rod 8, the threaded rod 8 is rotated. The threaded sleeve on the outer surface of the threaded rod 8 moves. The threaded sleeve 9 is rotatably connected to the support member 10 on the guide pipe 5 by a connecting rod. Therefore, when the threaded sleeve moves, it will lift the guide pipe 5 through the connecting rod, so that the guide pipe 5 can adjust its angle around the rotating shaft 6, thereby adjusting the height of one end of the guide pipe 5 to adapt to the height of the pump truck. At the same time, the rotation of the threaded rod 8 synchronously drives the worm gear. When worm 16 rotates, it meshes with worm wheel 17 on threaded rod 15, thus driving threaded rod 15 to rotate. The two sets of threaded sleeves 18 on the outer surface of threaded rod 15 will move towards each other and carry their respective connecting rods 20 to move. The other ends of the two sets of connecting rods 20 are rotatably connected to the top block 19 on the vertical rod 22. The vertical rod 22 is rotatably connected to the support 21 on the guide tube 5. Therefore, the guide tube 5 can be driven to adjust the angle around the rotating shaft 6, thereby adjusting the height of one end of the guide tube 5 and connecting it to the unloading hopper of the pump truck. This completes the installation and use, allowing the pump truck to discharge material for pouring operations.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
