Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy project construction equipment, in particular to a special low-slump concrete placing device for the casting of flood inlet and overflow sluices. Background Technique

[0002] In the construction of water conservancy projects, the casting work of flood inlet and overflow sluices is of great importance. Low-slump concrete has been widely used in the construction of water conservancy projects due to its unique physical properties. However, during the casting of flood inlet and overflow sluices, the working surface is often at a position much higher than the foundation surface. Moreover, since low-slump concrete cannot be transported by conventional conveying devices such as concrete pumps, it is very difficult for the prior art to effectively complete the concrete conveying operation through mechanical conveying methods. When using the traditional concrete placing method to transport low-slump concrete, there are often problems such as uneven placing and easy segregation, which seriously affect the casting quality.

[0003] The patent with the application number CN201810216523.8 discloses a concrete placing device, which includes a base, a vertical frame erected on the upper end surface of the base. A bearing seat is provided at the upper end of the vertical frame, and a slewing bearing is sleeved in the bearing seat. The lower end of the upper mounting seat is sleeved in the slewing bearing. A balance arm and a main beam are respectively arranged on both sides of the upper mounting seat, and a counterweight box is provided at the end of the balance arm; the feeding pipe includes a vertical pipe, a horizontal pipe, a rotating pipe and a discharging hose connected in sequence; a roller mounting cavity is provided on the lower end surface of the base, and a roller driving hydraulic cylinder and a rolling wheel are provided in the roller mounting cavity. The roller driving hydraulic cylinder is fixedly installed at the top of the roller mounting cavity, and the rolling wheel is installed at the lower end of the hydraulic telescopic rod of the roller driving hydraulic cylinder.

[0028] The special low-slump concrete distributing device for the pouring of this flood inlet sluice includes a crawler-type machine body 1000, a belt-type conveying mechanism 2000, a cushion layer 3000 and a scraping component 4000.

[0029] The crawler-type machine body 1000 and the belt-type conveying mechanism 2000 are transformed from commercially available crawler-type concrete distributors. One end of the belt-type conveying mechanism 2000 is installed on the crawler-type machine body 1000, and the other side of the belt-type conveying mechanism 2000 extends outside the crawler-type machine body 1000.

[0030] A plurality of blocking protrusions 2110 are provided on the surface of the conveyor belt 2100 of the belt-type conveying mechanism 2000. The plurality of blocking protrusions 2110 are sequentially distributed at intervals along the surface of the conveyor belt 2100. In the same blocking protrusion 2110, the end of the blocking protrusion 2110 on the front side of the running direction of the conveyor belt 2100 is the starting end of the blocking protrusion 2110, and the end of the blocking protrusion 2110 on the rear side of the running direction of the conveyor belt 2100 is the ending end of the blocking protrusion 2110. A smooth inclined surface 2111 is provided on the blocking protrusion 2110. One side of the inclined surface 2111 extends to the bottom of the starting end of the blocking protrusion 2110, and the other side of the inclined surface 2111 extends to the top of the ending end of the blocking protrusion 2110. Skirts 2120 are provided on both sides in the width direction of the conveyor belt 2100.

[0031] The cushion layer 3000 is built on the upper side of the base layer of the working environment. The upper end surface of the cushion layer 3000 has an inclination angle of 15° with the horizontal plane. During operation, the crawler-type machine body 1000 is located on the upper end surface of the cushion layer 3000.

[0032] The scraping component 4000 includes a scraping plate 4100, a scraping housing 4200, two counterweight blocks 4400 and two steel wire ropes 4300. The scraping plate 4100 is arranged at the corner on the upper side of the belt-type conveying mechanism 2000.

[0033] Both sides of the scraping housing 4200 are respectively fixed to the belt-type conveying mechanism 2000 at the upper corner through support plates. One end of the scraping plate 4100 extends into the scraping housing 4200 from the opening on the upper side of the scraping housing 4200. The other end of the scraping plate 4100 extends outside the scraping housing 4200 and abuts against the surface of the conveyor belt 2100 of the belt-type conveying mechanism 2000. The two steel wire ropes 4300 are respectively arranged on both sides of the scraping plate 4100. One end of the steel wire rope 4300 is fixed to the inner wall of the scraping housing 4200.

The belt-type conveying mechanism 2000 is driven by a motor to achieve stable concrete conveying. The design of the blocking protrusions 2110 and the inclined surfaces 2111 on the conveyor belt 2100 can ensure the stability and uniformity of the concrete during the conveying process and improve the pouring quality.

[0036] In actual use, the concrete is added through the feeding port of the crawler-type body 1000. Driven by the conveyor belt 2100, the concrete moves forward along the stable flow channel formed by the blocking protrusions 2110. Due to the design of the inclined surfaces 2111 of the blocking protrusions 2110, the concrete can maintain a uniform distribution during the movement, avoiding the occurrence of segregation. At the same time, the design of the skirt 2120 can prevent the concrete from overflowing during the conveying process and ensure the construction safety.
