Description

Technical Field

[0001] This utility model relates to the field of concrete pouring technology, and more specifically, to grouting equipment for precast concrete. Background Technology

[0002] Concrete grouting equipment is mainly used to mix slurry, cement, quicklime, gypsum, and aluminum powder paste suspension in a certain proportion into a tank, ensuring uniform mixing, and then promptly injecting the mixed slurry into a mold frame. It is widely used in various concrete production scenarios.

[0003] Chinese invention patent application number 202411363653.6 discloses a concrete grouting equipment and grouting method. The grouting equipment adds a mixing mechanism and an extrusion mechanism, which can prevent concrete from segregating and clumping, avoid clogging the nozzle, and improve the uniformity and smoothness of the output concrete. However, when producing large flat precast slabs, high-pressure spraying is prone to material splashing and it is difficult to achieve uniform injection, which can easily cause concrete to clump together, making it difficult to level later. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a grouting and pouring equipment for precast concrete that is not prone to splashing and is easy to process in subsequent processes.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A grouting and pouring equipment for precast concrete includes a gantry frame, a trolley mounted on the gantry frame, an installation frame at the bottom of the trolley, a feed pipe connected to the trolley, the feed pipe communicating with the installation frame, a nozzle connected to the installation frame, a telescopic tube installed inside the nozzle, and a scraper movably connected to the nozzle.

[0007] The present invention is further configured such that: the nozzle includes a mounting ring, the mounting ring is fixed on the mounting bracket, the telescopic tube is disposed on the side of the mounting ring away from the feed pipe, an inner ring sleeve is sleeved on the outside of the telescopic tube, one end of the inner ring sleeve is fixed on the mounting ring, the other end of the telescopic tube is connected to a connecting ring, an outer ring sleeve is rotatably connected to the connecting ring, and the outer ring sleeve is threadedly connected to the inner ring sleeve.

[0008] The present invention is further configured such that: the side of the connecting ring away from the telescopic tube is connected to a nozzle, the nozzle is horn-shaped, the small diameter end of the horn-shaped nozzle is connected to the connecting ring, and the large diameter end of the horn-shaped nozzle is configured as a vertical cylindrical opening.

[0009] The present invention is further configured such that: the scraper includes a movable ring, the movable ring is rotatably connected to the outer ring of the connecting ring, and a plurality of connecting rods are connected to the movable ring, the ends of the plurality of connecting rods being connected to a blade.

[0010] The present invention is further configured such that: the blade is in the shape of an isosceles triangle, the vertex of the blade faces away from the nozzle, and the lowest point of the blade is lower than the lowest point of the nozzle.

[0011] The present invention is further configured such that a plurality of ball bearings are provided on the connecting surface of the movable ring and the connecting ring.

[0012] The advantages of this utility model are:

[0013] 1. A telescopic tube is installed inside the nozzle. The two ends of the telescopic tube are connected to an installation ring and a connecting ring, respectively. An inner ring sleeve is installed on the installation ring, and an outer ring sleeve is rotatably connected to the connecting ring. The outer ring sleeve and the inner ring sleeve are threaded together. Rotating the outer ring sleeve can adjust the length of the telescopic tube, thereby flexibly adjusting the height of the nozzle according to the thickness of the structure to be poured, and preventing concrete splashing when the nozzle is too high.

[0014] 2. The nozzle is designed in the shape of a trumpet, with the small diameter end facing upward and the large diameter end facing downward, and the opening is designed as a straight cylinder. When the concrete is sprayed out of the nozzle, the flow area increases, thereby reducing the flow velocity and reducing the impact on the concrete below. In addition, the straight cylinder structure at the opening restricts the flow direction of the concrete to downward, thereby reducing splashing.

[0015] 3. The scraper is equipped with a movable ring, which is rotatably connected to the connecting ring. When the trolley is running, the scraper is dragged behind by the connecting ring under the action of concrete resistance, which can scrape the concrete flat, thereby reducing the accumulation of concrete and facilitating subsequent processing.

[0024] Please see Figure 1-4 The present invention provides the following technical solution:

[0025] The precast concrete grouting equipment includes a gantry frame 1, a trolley 2 mounted on the gantry frame 1, an installation frame 3 at the bottom of the trolley 2, a feed pipe 4 connected to the trolley 2 and communicating with the installation frame 3, and a nozzle 5 connected to the installation frame 3. The trolley 2 can move laterally or longitudinally on the gantry frame 1 so that concrete can be poured into the mold below through the nozzle 5. The nozzle 5 is equipped with a telescopic tube 52. By adjusting the length of the telescopic tube 52, the height of the nozzle 5 above the mold can be adjusted, thereby reducing the spraying distance and preventing concrete splashing. A scraper 6 is movably connected to the nozzle 5. The scraper 6 is dragged by the nozzle 5 under the action of concrete resistance, so that the scraper 6 is always behind the nozzle 5 in the direction of travel, which can roughly scrape the concrete poured into the mold, reduce concrete accumulation, and facilitate subsequent processing.

[0026] The nozzle 5 includes a mounting ring 51, which is fixed on the mounting bracket 3. The telescopic tube 52 is located on the side of the mounting ring 51 away from the feed tube 4. An inner ring sleeve 55 is fitted on the outside of the telescopic tube 52. One end of the inner ring sleeve 55 is fixed on the mounting ring 51. The other end of the telescopic tube 52 is connected to a connecting ring 53. An outer ring sleeve 56 is rotatably connected to the connecting ring 53. The outer ring sleeve 56 is threadedly connected to the inner ring sleeve 55. By rotating the outer ring sleeve 56, the length of the telescopic tube 52 can be adjusted, thereby changing the distance between the nozzle 5 and the mold.

[0027] The connecting ring 53 is connected to a nozzle 54 on the side opposite to the telescopic pipe 52. The nozzle 54 is funnel-shaped, with the small diameter end of the funnel connected to the connecting ring 53. The large diameter end of the funnel is set as a vertical cylinder. When the concrete flows through the nozzle 54, the flow area increases and the flow velocity decreases, thereby reducing the impact on the structure below and reducing concrete splashing. At the same time, the straight cylinder structure at the end restricts the flow direction of the concrete to vertical downward, preventing the concrete from overflowing outward along the nozzle 54 during the pouring process.

[0028] The scraper 6 includes a movable ring 61, which is rotatably connected to the outer ring of the connecting ring 53. Several balls 7 are provided on the connecting surface of the movable ring 61 and the connecting ring 53. Several connecting rods 62 are connected to the movable ring 61. The ends of the several connecting rods 62 are connected to a blade 63. The blade 63 is in the shape of an isosceles triangle. The vertex of the blade 63 faces away from the nozzle 5, and the lowest point of the blade 63 is lower than the lowest point of the nozzle 54.

[0029] The movable ring 61 allows the scraper 6 to rotate around the nozzle 5. During the movement of the trolley 2, the nozzle 5 and the trolley move in the same direction, and the blade 63 scrapes the concrete synchronously. Due to the resistance of the concrete, the blade 63 is always located on the side of the nozzle 5 away from the direction of movement, thus ensuring that the scraper 6 can always be behind the nozzle 5 to roughly scrape the concrete sprayed on it, ensuring the scraping effect and facilitating subsequent processing.

[0030] Specifically, a telescopic tube 52 is installed inside the nozzle 5. The two ends of the telescopic tube 52 are respectively connected to an installation ring 51 and a connecting ring 53. An inner ring sleeve 55 is installed on the installation ring 51, and an outer ring sleeve 56 is rotatably connected to the connecting ring 53. The outer ring sleeve 56 is threadedly connected to the inner ring sleeve 55. Rotating the outer ring sleeve 56 can adjust the length of the telescopic tube 52, thereby flexibly adjusting the height of the nozzle 54 according to the thickness of the structure to be poured, preventing concrete splashing when the nozzle 54 is too high.

[0031] The nozzle 54 is designed in the shape of a trumpet, with the small diameter end facing upward and the large diameter end facing downward, and the opening is designed in the shape of a straight cylinder. When concrete is sprayed out from the nozzle 54, the flow area increases, thereby reducing the flow velocity and reducing the impact on the concrete below. In addition, the straight cylinder structure at the opening restricts the flow direction of the concrete to the downward, thereby reducing splashing.

[0032] The scraper 6 is equipped with a movable ring 61, which is rotatably connected to the connecting ring 53. When the trolley is running, the scraper 6 is dragged behind by the connecting ring 53 under the action of concrete resistance, which can scrape the concrete flat, thereby reducing the accumulation of concrete and facilitating subsequent processing.
