Problems solved by technology

[0002] In the past, large-volume concrete pouring mainly used automobile pumps or towed floor pumps to pump into the mold. This method is noisy and expensive, and is not suitable for the construction of the internal structure of the station.
In the prior art, there is also a scheme of using chutes for concrete delivery, such as CN107143348A, a concrete delivery device and method for urban underground mine tunnel construction, which uses chutes for concrete delivery, but the problem with this solution is that when the pouring warehouse The surface area is large, and it is difficult to achieve uniform feeding with the conveying method of the chute
CN211924185U has recorded a kind of pneumatic concrete delivery system for cast-in-place concrete lining of underground engineering, but whether the delivery efficiency of this scheme and the delivery process will cause aggregate separation is still unclear

Embodiment 1

[0028] Such as figure 1 , 2 In, 8, a kind of unloading device that is applicable to the inner structure construction of subway station, comprises hopper and feeding pipe conveying structure, in the position close to pouring warehouse 13, the bottom of third hopper 5 and feeding pipe conveying structure is hinged, the first The three hoppers 5 are connected with one end of the feeding hose 6, and the other end of the feeding hose 6 is connected with the traction device, and a steel wire rope is arranged in the traction device, and the steel wire rope is connected with the feeding hose 6 for pulling the free end of the feeding hose 6 Swing in the scope of pouring bin 13, to discharge material evenly. Preferably, the feeding hose 6 is a corrugated tube or a rubber tube. If a rubber tube is used, support rings are provided at intervals in the rubber tube to prevent the rubber tube from being completely closed and affecting the cutting efficiency.

[0029] The preferred solution...

Embodiment 2

[0032] On the basis of Example 1, the preferred scheme is as figure 1 Among them, the traction device is a pulley 7, and the pulley 7 is preferably fixed on the top of the pouring bin 13, or it can be on the top side, and the wire rope goes around the pulley 7 to connect with the feeding hose 6. This solution is suitable for smaller pouring bins 13, and has a simple structure, and operators can operate outside the bins.

Embodiment 3

[0034] On the basis of Example 1, the preferred scheme is as figure 2 Among them, the traction device is a pulling device 8, the pulling device 8 includes at least one track, the track is fixedly installed on the top or side of the pouring warehouse 13, guide wheels are provided at both ends of the track, and there are Dolly, at least one end of the dolly is connected with the steel wire rope, and the steel wire rope is connected with the free end of the feeding hose 6 around the guide wheel. When the trolley is driven to walk along the track, it drives the steel wire rope to pull up or put down the free end of the feeding hose 6, so as to realize uniform distribution.

Abstract

The invention provides a blanking device suitable for construction of an internal structure of a subway station, which comprises hoppers and a feeding pipe conveying structure, a third hopper is hinged with the bottom of the feeding pipe conveying structure at a position close to a pouring bin, the third hopper is connected with one end of a feeding hose, and the other end of the feeding hose is connected with a traction device; a steel wire rope is arranged in the traction device, connected with the feeding hose and used for pulling the free end of the feeding hose to swing within the range of the pouring bin so as to achieve even discharging. The combination of the traction device and the feeding hose is adopted, so that uniform feeding in the pouring bin is realized at lower cost.

Description

technical field [0001] The invention relates to the field of subway station internal construction, in particular to a material cutting device suitable for the construction of the internal structure of a subway station. Background technique [0002] In the past, large-volume concrete pouring mainly used automobile pumps or towed floor pumps to pump into the mold. This method is noisy and expensive, and is not suitable for the construction of the internal structure of the station. In the prior art, there is also a scheme of using chutes for concrete delivery, such as CN107143348A, a concrete delivery device and method for urban underground mine tunnel construction, which uses chutes for concrete delivery, but the problem with this solution is that when the pouring warehouse The surface area is large, and it is difficult to achieve uniform feeding by using the conveying method of the chute.
