Description

Technical Field

[0001] The utility model relates to the technical field of concrete discharge devices, in particular to a concrete anti-segregation discharge device. Background Art

[0002] During the subway construction process, there are two main ways to transport concrete underground. One is to use a pump truck and a pump pipe to directly transport and pour. This pouring method is suitable for the wellhead and the underground line close to the wellhead; the other is to first transport the ground concrete to the underground turnover container, and then transport the concrete to the designated location for pouring by rail car. There are two main ways to transport concrete from the ground to the underground turnover container: one is to use a pump truck to pump concrete into the container, which is costly; the other is to set up a concrete discharge device at the wellhead, which can greatly save the cost of concrete transportation. At present, there are two main types of vertical concrete discharge devices: one is to use a rubber hose connection at the pipe joint, which is convenient for bending the pipe, thereby slowing down the falling speed of concrete and preventing segregation, but the rubber hose connection bend is very easy to damage. Although the rubber hose is low in cost, each maintenance requires high-altitude operation, and the total maintenance cost is still high; the other is to change the rubber hose to a string tube, but this method still cannot withstand the huge impact caused by the free acceleration of concrete stones. The problem of fragility has not been solved, and the cost and maintenance cost of the string tube are higher than that of the rubber hose. The above-mentioned hose and tube type discharge device, when the height of the receiving container changes greatly due to working conditions, the length of the hose and tube cannot adapt to the current height of the receiving container, and the length of the hose and tube needs to be changed before normal use, which is extremely inconvenient for on-site operation. Therefore, the construction site urgently needs a concrete anti-segregation discharge device that is easy to operate, can quickly adjust the receiving height, and is maintenance-free during the service life.

The anti-segregation mechanism 1 is connected to the supporting mechanism 2, the discharging mechanism 3 is arranged at the bottom of the anti-segregation mechanism 1, and the auxiliary discharging mechanism 4 is connected to the discharging mechanism 3. The anti-segregation mechanism 1 includes a hopper 101, a first pipe 102 and a blocking structure 103. The number of hoppers 101 is the same as the number of supporting mechanisms 2. Each hopper 101 is connected to the supporting mechanism 2. A blocking structure 103 for limiting the flow rate of concrete is provided in each hopper 101. Two adjacent hoppers 101 are connected by a first pipe 102, and the first pipe 102 has an angle with the vertical direction.

[0034] The support mechanism 2 is fixed to the wellhead platform by expansion bolts, and multiple support mechanisms 2 are respectively fixed to multiple wellhead platforms with different heights. Multiple wellhead platforms are arranged in sequence from top to bottom along the well wall. After two adjacent support mechanisms 2 are connected, there is an angle with the horizontal direction. After the bottom of the hopper 101 passes through the support mechanism 2 downward, the hopper 101 is clamped with the support mechanism 2, and the clamping parts of the hopper 101 and the support mechanism 2 are welded to fix the position of the hopper 101 and the support mechanism 2, and the two adjacent hoppers 101 are connected by the first pipe 102. The two adjacent hoppers 101 are connected The first pipe 102 of 101 has an angle with the vertical direction, and at the same time, the first pipe 102 has an angle with the horizontal direction, so that the contact area between the concrete entering the hopper 101 and the first pipe 102 is increased when it is transmitted downward through the first pipe 102, and the flow rate of the concrete is reduced. The blocking structure 103 is arranged in the hopper 101, and the flow rate of the concrete can be further limited by the blocking structure 103. At the same time, the blocking structure 103 can also isolate large stones in the concrete, thereby achieving the purpose of reducing the impact force of the concrete, extending the service life of the discharge device, and preventing the concrete from segregating.

[0035] The blocking structure 103 is a grille.

[0036] The blocking structure 103 matches the shape of the hopper 101 , and the blocking structure 103 can be fixed in the hopper 101 to limit the speed of concrete.

[0037] The blocking structure 103 is a mesh grille structure welded by round steel and flat steel. Each square of the mesh structure is the same size. When concrete flows into the hopper 101, the blocking structure 103 in the hopper 101 filters the concrete to prevent large stones in the concrete from flowing into the first pipe 102 and causing blockage of the first pipe 102, thereby extending the service life of the discharge device. At the same time, the blocking structure 103 can also reduce the flow rate of the concrete to prevent the concrete from segregating.

[0038] In another possible embodiment, the blocking structure 103 is a multi-layer buffer zone (not shown in the figure) welded with steel bars, the multi-layer buffer zone is alternately arranged on the inner walls of the hopper 101 facing each other, the length of the steel bars is less than the length of the hopper 101, the first layer of buffer zone is arranged on the left inner wall of the hopper 101, and the second layer of buffer zone is arranged on the right inner wall of the hopper 101, or the first layer of buffer zone is arranged on the front inner wall of the hopper 101, and the second layer of buffer zone is arranged on the rear inner wall of the hopper 101, and the first layer of buffer zone and the second layer of buffer zone are spaced apart in the height direction of the hopper 101, the first layer of buffer zone and the second layer of buffer zone both include a plurality of steel bars, the plurality of steel bars are arranged in a row along the inner wall of the hopper 101, the end of each steel bar along the length direction is welded to the inner wall of the hopper 101, and the free end of the steel bar extends in the horizontal direction, the first layer of buffer zone and the second layer of buffer zone overlap, so as to facilitate multiple filtering and speed limiting after the concrete enters the hopper 101.

The top of the elbow 105 is connected to the discharge port of the upper hopper 101 by bolts. The extension line of the end of the elbow 105 away from the discharge port of the hopper 101 can reach the inlet of the lower hopper 101. Then, the elbow 105 can be used to connect the two adjacent hoppers 101. The end of the first pipe body 104 along the length direction is connected to the end of the elbow 105 away from the feeding port of the hopper 101 by bolts. The end of the first pipe body 104 away from the elbow 105 reaches the feeding port of the hopper 101 located at the bottom. The first pipe body 104 has an angle with the vertical direction. When the concrete passes through the first pipe body 104, it contacts the inner wall of the first pipe body 104. The first pipe body 104 extends obliquely downward to increase the contact area between the concrete and the inner wall of the first pipe body 104.

The extension piece 107 is arranged on the hopper body 106 to effectively prevent the first pipe body 104 from splashing or overflowing when conveying concrete to the hopper body 106. At the same time, the side of the extension piece 107 at the top of the wellhead away from the wellhead is an opening, which is convenient for the concrete mixing tank truck on the ground to convey concrete into the hopper 101. The other three sides of the extension piece 107 are all extended upward in the vertical direction. The concrete is quickly conveyed from the concrete mixing truck to the hopper 101 at the top of the wellhead at a 45-degree angle.

[0044] The first support part 201 and the second support part 202 are both made of steel pipes. The shape of the outer wall of the accommodating chamber 204 matches that of the hopper body 106, so as to facilitate fixing the hopper body 106 in the accommodating chamber 204. The connecting part 203 is a horizontal outward extension of the steel pipe on the left and right sides of the accommodating chamber 204. The ends of the connecting part 203 away from the accommodating chamber 204 are provided with a first connecting piece 2031 and a second connecting piece 2032.

[0045] like Figure 4 As shown, the discharging mechanism 3 includes a second pipe 301 , a chute 302 and a connecting hole 303 . The second pipe 301 is rotatably connected to the chute 302 . There are multiple connecting holes 303 , which are symmetrically arranged on the side walls of both sides of the chute 302 .

[0049] The winch 401 pulls the traction component 403 to drive the chute 302 at the end of the traction component 403 to rotate up and down along the rotation axis 304, so as to prevent the chute 302 from affecting the normal passage of the rail vehicle. Before the concrete is released, the winch 401 drops the end of the chute 302 into the hopper of the transport vehicle through the traction component 403, so as to prevent the concrete from splashing when it falls from the chute 302 to the hopper of the transport vehicle.
