Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring, in particular to a chute for large-angle concrete pouring. Background Art

[0002] Chutes are a tool commonly used for high-angle concrete pouring, especially for vertical or nearly vertical structures such as tunnels, mine walls, shafts, etc. The chute is made of wear-resistant materials and can be fixed along the pouring surface to form a continuous channel from the top to the bottom, so that concrete can flow from top to bottom under the action of gravity, achieving smooth and uniform pouring. The chute for high-angle concrete pouring is a device specially designed for safe and efficient transportation and pouring of concrete at large inclination angles.

[0003] The chute for high-angle pouring is particularly suitable for situations where there is a large height difference between the working surface and the concrete pouring point, and direct pouring or pumping is not applicable or feasible. Its design allows the concrete to slide smoothly from top to bottom at a steeper angle, ensuring that the concrete can still maintain good fluidity and uniformity when pouring at a high drop. However, when pouring at a large angle, the aggregate particles and cement slurry of the concrete itself are discharged too fast due to gravity, and segregation is prone to occur, that is, the aggregate particles and cement slurry are separated. The coarse aggregate is more susceptible to gravity than the cement slurry due to its higher density and falls faster. This difference leads to relative movement between the coarse aggregate and the cement slurry, that is, the coarse aggregate tends to concentrate at the bottom of the chute, while the cement slurry floats upward relatively, thus forming a segregation phenomenon.

[0004] The existing chute for high-angle concrete pouring is not convenient for buffering the aggregate particles in the concrete during use, which easily leads to the separation of the aggregate particles and the cement paste, affects the pouring quality of the concrete, and reduces the structural strength of the concrete after molding.

[0014] As a preferred embodiment of the utility model for a chute for pouring concrete at a large inclination angle, the left end of the screw rod is fixedly connected to a hand wheel, and the nut sleeve is located in the inner cavity of the frame and movably connected to the inner wall thereof.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. The utility model is provided with a pouring mechanism, which can facilitate the guidance of the concrete to be poured, so that the concrete is poured at the construction location. The concrete is poured into the hopper and guided into the trough body by the hopper. The trough body is inclined so that the concrete flows down due to gravity and finally flows into the location where it needs to be poured.

[0017] 2. The utility model can buffer the concrete flowing inside the trough body by setting a buffer mechanism to prevent the aggregate particles in the concrete from separating from the cement slurry. The sliding sleeve is set on the slide rail, and the position of the sliding sleeve on the surface of the slide rail is changed according to the required buffer position. After the adjustment is completed, the screw rod is passed through the sliding sleeve and screwed into the jack to fix the sliding sleeve on the slide rail. When the concrete flows inside the trough body, it first contacts the rotating plate, and the rotating plate drives the rotating rod to rotate inside the rotating seat, so that the rotating plate rotates in an arc. During the arc rotation of the rotating seat, the rubber sleeve is compressed, and the limit plate is pressed against the rubber sleeve. The surface of the rubber sleeve is limited, and the arc spring inside the rubber sleeve is compressed during the deformation of the rubber sleeve, so that the arc spring deforms to absorb the impact force. At the same time, the first arc plate slides on the surface of the second arc plate to limit the deformation range of the rubber sleeve, so that the rubber sleeve can only retract in an arc shape. By slowing down the falling speed of concrete, the separation of coarse aggregate and cement paste caused by gravity difference is suppressed, ensuring that the various components of concrete are evenly distributed during the sliding process, avoiding the accumulation of aggregate at the bottom and the floating of the paste, thereby maintaining the intrinsic quality of the concrete and ensuring its mechanical properties and durability.

[0018] 3. The utility model can adjust the angle of the pouring mechanism by setting an angle adjustment mechanism, so that the pouring mechanism can be poured at a large angle. The user rotates the screw by the hand wheel, and the screw drives the nut sleeve to slide inside the frame, and the nut sleeve drives the adjustment arm on its top to rotate, and the adjustment arm drives the rotating block up and down or down, and the rotating block drives the left end of the frame to rotate, thereby changing the angle of the frame. During the rotation of the frame, the support rod is driven to rotate inside the connecting seat, and the support rod and the connecting seat support the right end of the trough body. Different pouring positions and heights may require different chute inclination angles. The pouring mechanism with adjustable angle can flexibly adjust the inclination according to actual needs, adapt to various complex terrain conditions and building layouts, such as deep foundation pits, slopes, viaduct piers, high-rise building core tubes, etc., to ensure that the concrete can reach the pouring point smoothly and accurately.

DETAILED DESCRIPTION

[0026] See also Figure 1-Figure 6 A chute for pouring concrete at a large inclination angle comprises a pouring mechanism 1, a plurality of buffer mechanisms 2 are installed on both the front and rear sides of the pouring mechanism 1, and an angle adjustment mechanism 3 is connected to the bottom of the pouring mechanism 1.

[0027] Furthermore, the casting mechanism 1 includes a trough body 101 , and the front and rear sides of the trough body 101 are fixedly connected with slide rails 103 .

[0029] Furthermore, the slide rail 103 is provided with a plurality of insertion holes 102 for use with the screw rod 204 .

[0030] By setting up the pouring mechanism 1, it is convenient to guide the concrete to be poured so that the concrete can be poured at the construction location. The concrete is poured into the feeding hopper 105 and guided into the trough body 101 by the feeding hopper 105. The trough body 101 is inclined so that the concrete flows downward due to gravity and finally flows into the location where it needs to be poured.

[0032] Furthermore, the rotating plate 201 and the limiting plate 205 are movably connected to the inner wall of the tank body 101 .

[0033] By setting the buffer mechanism 2, it is convenient to buffer the concrete flowing inside the trough body 101 to prevent the aggregate particles and cement slurry in the concrete from separating. The sliding sleeve 203 is sleeved on the slide rail 103, and the position of the sliding sleeve 203 on the surface of the slide rail 103 is changed according to the required buffer position. After the adjustment is completed, the screw 204 passes through the sliding sleeve 203 and is screwed into the socket 102 to fix the sliding sleeve 203 on the slide rail 103.

By slowing down the falling speed of the concrete, the separation of the coarse aggregate and the cement paste due to the gravity difference is suppressed, ensuring that the various components of the concrete are evenly distributed during the sliding process, avoiding the accumulation of aggregates at the bottom and the floating of the paste, thereby maintaining the intrinsic quality of the concrete and ensuring its mechanical properties and durability.

[0036] By setting the angle adjustment mechanism 3, it is convenient to adjust the angle of the pouring mechanism 1, so that the pouring mechanism 1 can be poured at a large angle. The user rotates the screw rod 307 through the hand wheel 302, and the screw rod 307 drives the nut sleeve 306 to slide inside the frame 301. The nut sleeve 306 drives the adjustment arm 303 on its top to rotate, and the adjustment arm 303 drives the rotating block 304 up and down or down, and the rotating block 304 drives the left end of the frame 301 to rotate, thereby changing the angle of the frame 301.
