Description

TECHNICAL FIELD

[0001] The utility model belongs to water conservancy construction equipment technical field especially is related to a kind of concrete pouring equipment for water conservancy dam engineering construction. BACKGROUND

[0002] Concrete pouring is important when water conservancy dam is built, and dam pouring requires a large amount of concrete, which is difficult for concrete transport vehicles to transport directly to the mountains and valleys for dam pouring. The prior art establishes a steel frame sling type translation cable machine in the mountains and valleys, the concrete transport vehicle unloads the mixed concrete into the sling tank at the unloading platform, and the sling tank is translated and hoisted to the top of the dam by the cable machine, and then vertically lowered to the unloading height to unload the concrete.

[0003] The concrete sling tank is a common pouring equipment for water conservancy dam concrete pouring, and the ordinary sling tank does not have a heat preservation function, and its top end is also an open structure. Water conservancy dam pouring has high temperature requirements for concrete, and the temperature of the concrete required for pouring cannot be too high or too low. In the case of low construction environment temperature, insulation measures need to be taken for the sling tank to reduce the loss of concrete temperature inside. The prior art sets a tank cover on the top of the tank body to enhance the heat preservation effect inside the tank body, for example, the patent with publication number CN219750651U proposes a concrete sling tank with heat preservation function, a tank cover is arranged on the upper part of the tank body to close the opening of the tank body, and a plurality of snap locks are arranged between the tank body and the tank cover to fix the tank cover and the tank body. Although the above-mentioned patent proposes to set a tank cover, the tank cover and the tank body are fixed by snap locks, and before the concrete in the concrete transport vehicle is unloaded into the tank body, workers need to manually open the snap locks and turn open the tank cover. After the concrete is poured into the tank, the workers need to turn off the tank cover. The operation of opening and closing the tank cover is time-consuming and laborious, and the unloading platform between the sling tank and the concrete transport vehicle built near the cliff during water conservancy dam concrete pouring has a high risk coefficient when relying on manual opening and closing of the tank cover.

[0004] The utility model aims to provide a concrete pouring equipment for water conservancy dam engineering construction, which sets an automatically openable and closable tank cover on the top of the sling tank body to solve the problem of manual opening and closing of the existing tank cover.

[0005] The utility model is implemented by the following technical solutions:

[0006] A concrete pouring equipment for water conservancy dam engineering construction, comprising a sling tank body, a hoisting frame is welded to the outer side wall of the sling tank body, an openable and closable tank cover is arranged on the top of the sling tank body, the tank cover is composed of two symmetrical left and right cover plates, both cover plates are hinged to the top end of the sling tank body, and both cover plates are opened and closed in a rotating manner.

[0007] The left side and the right side of the hanging tank body are respectively provided with a connecting rod mechanism for controlling the opening and closing of the cover plates, and the two connecting rod mechanisms are symmetrically arranged along the central axis of the hanging tank body. One of the connecting rod mechanisms can control the opening and closing of one of the cover plates, and the other connecting rod mechanism can control the opening and closing of the other cover plate. The two cover plates are opened and closed at the same time.

[0008] The connecting rod mechanism comprises a vertical rod, a first connecting rod, a second connecting rod, a sliding sleeve, a sliding rod and a third connecting rod.

When the hanging tank body and the counterweight seat are suspended, the two cover plates are in the closed state, and when the lifting frame of the hanging tank body and the counterweight seat stand on the ground, the two cover plates are in the open state. According to the contact and suspension of the counterweight seat, the automatic opening and closing of the tank cover can be realized.

[0009] Further, the bottom end of the hanging tank body is provided with a discharge port, and the bottom end of the hanging tank body is provided with a discharge gate for opening and closing the discharge port.

[0010] Further, the lifting frame comprises four vertical columns and a bottom frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This concrete pouring equipment is used to transport concrete during the pouring of concrete for hydraulic dams. Utilizing a steel-framed cable-stayed crane built in the mountain valley, concrete trucks unload the mixed concrete into the suspended tank at the unloading platform. The crane then horizontally moves the tank to the top of the dam, and then vertically lowers it to the unloading height to unload the concrete. In low-temperature environments, a lid is fitted to the top of the tank. Two linkage mechanisms control the opening and closing of the two lid plates. When the counterweight is positioned on the unloading platform, the linkage mechanisms automatically open the lid, leaving the top of the tank open, facilitating the unloading of concrete trucks at the unloading platform. The mixed concrete is unloaded into the suspended tank. When the counterweight is suspended, the linkage mechanism can control the tank cover to close automatically, which can insulate the concrete inside and reduce the loss of concrete temperature in low-temperature environments. The top of the suspended tank of this pouring equipment is equipped with an automatically opening and closing tank cover. Before the concrete is unloaded from the concrete truck into the suspended tank, there is no need for workers to manually flip and open the tank cover. After the concrete is put into the tank, there is no need for workers to flip and close the tank cover. The automatic opening and closing structure of the tank cover saves time and labor. Furthermore, by building an unloading platform between the suspended tank and the concrete truck near the cliff, there is no need to rely on manual opening and closing of the tank cover, which can prevent workers from falling due to opening and closing the tank cover.
