Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing devices, in particular to a height adjustment mechanism for a coarse aggregate active powder concrete mixing device. Background Art

[0002] Coarse aggregate reactive powder concrete (RPC) boasts high strength, ductility, and durability, making it suitable for long-span bridge decks. Its main components include coarse aggregate, fine aggregate, silica fume, microspheres, cement, water, admixtures, and steel fiber. Because the coarse aggregate, water, and core material in RPC require on-site mixing, the mixing apparatus must be moved and adjusted during mixing. Furthermore, the presence of coarse aggregate in the concrete requires strict control of the discharge height during on-site mixing to prevent concrete segregation caused by excessive mixing height.

[0023] Below, refer to Figure 1-2 A height adjustment mechanism for a coarse aggregate reactive powder concrete mixing device according to an embodiment of the present invention will be described in detail.

[0024] like Figure 1-2 As shown, according to an embodiment of the present invention, a height adjustment mechanism for a coarse aggregate active powder concrete mixing device is provided, the mixing device includes a mixing box for mixing concrete, the height adjustment mechanism includes an operating platform 101, four leg frames 103, four sliding legs 102 and a drive assembly, the bottom of the mixing box is fixed on the operating platform 101, and the bottom of the operating platform 101 is provided with a moving wheel group 1000; the four leg frames 103 are respectively fixed at the four corners of the operating platform 101; the sliding legs 102 are slidably installed in the leg frames 103 so that the operating platform 101 can move up and down; the drive assembly is installed at the bottom of the operating platform 101, and the drive assembly is respectively connected to each of the sliding legs 102 for driving the sliding legs 102 to slide up and down in the leg frames 103.

[0025] It should be noted that the mixing device is provided with a mixing box specifically for containing concrete for mixing concrete, and the mixing of concrete is completed in the mixing box. The height adjustment mechanism of the embodiment of the utility model is used to support the mixing box, move and lift the mixing box.

[0026] In this embodiment, a height adjustment mechanism is formed by the operating platform 101, the leg frame 103, the sliding leg 102 and the driving assembly. The unloading height adjustment and movement functions are realized through the height adjustment mechanism and the moving wheel group 1000, which facilitates the movement and lifting control of the entire stirring device and improves the stirring efficiency and performance of the stirring device.

[0027] In one embodiment, the drive assembly includes a drive device 104, a transmission gear rod 101000, two gear rod brackets 106 and two rotating shafts 107. The drive device 104 is fixed to the bottom center of the operating platform 101 and a gear is installed on its output shaft. The two gear rod brackets 106 are symmetrically fixed on both sides of the drive device 104. The center of the transmission gear rod 101000 is engaged with the gear on the output shaft of the drive device 104, and its two ends are respectively installed in the gear rod brackets 106 and can slide along the gear rod brackets 106. Two rotating shafts 107 are rotatably mounted on the rack support 106 and perpendicular to the transmission rack 101000. A gear is fixed to the center of each rotating shaft 107 and meshes with the transmission rack 101000. Gears are also fixed to both ends of each rotating shaft 107. Racks are provided on the front of the two sliding legs 102 at one end of the transmission rack 101000, while racks are provided on the back of the two sliding legs 102 at the other end of the transmission rack 101000. The gears at the ends of the rotating shafts 107 mesh with the racks on the corresponding leg frames 103. Thus, the height of the operating platform 101 can be adjusted under the drive of the drive device 104, thereby facilitating adjustment of the height of the mixing box, effectively controlling the discharge height, preventing concrete segregation, and ensuring the quality of on-site pouring.

Beneficial effects are achieved: The height adjustment mechanism is formed by the operating platform 101, the leg frame 103, the sliding legs 102, and the drive assembly.
