Problems solved by technology

However, since the small amount of concrete entering the chute is very easy to produce aggregate separation, a small amount of stones separated from the concrete will quickly slide down the chute or rush out of the chute, causing aggregate separation in the front-end concrete. Quality has a big impact
At the same time, the stones jumping out of the chute have great energy, which poses a great safety risk to the construction personnel and equipment below.

Embodiment 1

[0031] like Figure 1-2 Among them, a concrete chute with a counterweight type buffer device includes a chute body 1, and the chute body 1 is provided with a door plate 3, the door plate 3 includes an upper rectangular plate and a lower half-circle plate part, and the lower part of the door plate 3 The semi-circular plate is fitted to the inner wall of the chute body 1, the upper end of the rectangular plate of the door plate 3 is provided with a counterweight buckle arm 4, and the counterweight buckle arm 4 is provided with a counterweight block 5, on the rectangular plate of the door plate 3 close to the position of the semicircular plate A door shaft hole 301 is penetrated on the upper part, and a door shaft 6 is penetrated in the door shaft hole 301;

[0032] The top surfaces of the two sides of the chute body 1 are provided with hinge seats 2, and both ends of the door shaft 6 are provided on the hinge seats 2;

[0033] One side of the chute body 1 is provided with a box...

Embodiment 2

[0035] like Figure 3-5 As shown, on the basis of Embodiment 1, the box body 7 is provided with a partition, and the partition plate divides the box body 7 into an upper cavity 701 at the upper part and a lower cavity 702 at the lower part, and the upper cavity 701 tops The upper cavity 701 is provided with a horizontal guide rod 9 , and the guide rod 9 is arranged through the slider 10 .

[0036] In a preferred solution, a convex column 11 is provided at the bottom of the guide rod 9, a strip hole 703 is provided on the partition between the upper cavity 701 and the lower cavity 702, and the convex column 11 passes downward through the strip hole 703 and extend into the lower cavity 702;

[0037] The lower cavity 702 is provided with a horizontal rotating roller 12 , the outer wall of the rotating roller 12 is provided with a guide groove 13 , and the lower end of the convex column 11 is arranged in the guide groove 13 .

[0038] In a preferred solution, the guide groove 13...

Embodiment 3

[0046] On the basis of embodiment 2, the application of the above-mentioned concrete chute with a counterweight buffer device is specifically:

[0047] The chute body 1 is inclined along the conveying path;

[0048] Concrete conveyance work is performed using the chute body 1 .

[0049] like figure 1 As shown, in the process of conveying concrete, the aggregate formed by the separation of the front section of the concrete is blocked by the door panel 3 and stops, and then the concrete is transported to the door panel 3 together with the aggregate and continues to flow after the door panel 3 is pushed up, and the door panel 3 is affected by the concrete. Rotate downward, and the slider 10 is driven by the connecting rod 8 to move in the direction of the hinge seat 2 in the upper cavity 701. At this time (such as image 3 shown), the convex column 11 at the bottom of the slider 10 moves to the maximum stroke position along the straight section 131, and finally moves to the end...

Abstract

A concrete chute with a counterweight buffer device and an application thereof, comprising a chute body, a door plate is arranged in the chute body, the door plate comprises an upper rectangular plate and a lower half-circular plate part, and the semi-circular plate at the lower part of the door plate is arranged on the inner wall of the chute , the upper end of the rectangular plate on the door plate is provided with a counterweight buckle arm, the counterweight buckle arm is provided with a counterweight block, a door shaft hole is drilled on the door plate, and a door shaft is drilled in the door shaft hole; A hinge seat is arranged on the surface, and both ends of the door shaft are arranged on the hinge seat; a box body is arranged on one side of the chute body, a slider is arranged in the box, a connecting rod is arranged on the slider, and one end of the connecting rod is hinged to the slider The other end is hinged to one side of the rectangular plate at the upper part of the door panel. The concrete application of the concrete chute is that the chute body is inclined along the conveying path, and the concrete conveying operation is carried out through the chute body. By adopting the above structure, the present invention can solve the existing problems in the prior art and realize a safer concrete conveying operation process.

Description

technical field [0001] The invention relates to the field of concrete conveying equipment, in particular to a concrete chute with a counterweight type buffer device and its application. Background technique [0002] In the construction of the roller compacted concrete gravity dam, the dam site is in the valley, and it is very difficult to transport the roller compacted concrete into the silo. [0003] It is a simple, convenient, economical and effective construction method to use chute to transport concrete in water conservancy projects. However, since a small amount of concrete that begins to enter the chute is prone to aggregate separation, a small amount of stones separated from the concrete will quickly slide down the chute or rush out of the chute, resulting in aggregate separation of the front-end concrete, which is very difficult for concrete construction. Quality has a greater impact. At the same time, the boulders jumping out of the chute have large energy, which ...
