[0002] The construction method of open cut + dark cut is usually adopted for the entrances and exits of urban subways. Due to the short length of the open cut structure and the deep excavation depth, it is impossible to use the traditional ramp excavation method to transport the slag. Usually, a slag bucket is used in combination with a truck crane to transport the slag. The traditional slag bucket is a closed bottom and open top structure. The top of the slag bucket is provided with a lifting point, and there is no slag discharge port at the bottom of the slag bucket. When unloading the slag, the hook of the single-side lifting point needs to be manually removed, and then the slag is unloaded by lifting on one side. The lifting operation has high risks, low operating efficiency, and is easy to cause personal injury. Utility Model Content

[0005] In the utility model, when the piston rods of the hydraulic oil cylinders on both sides extend or retract, the two opening and closing plates can be driven to move simultaneously through the hoist chain, and the two opening and closing plates can rotate around their respective hinge points to realize the opening or closing of the slag discharge port, so that the slag can be discharged from the bottom of the slag bucket. By controlling the hydraulic oil cylinder, the remote control of the slag discharge port switch of the slag bucket can be realized. The utility model adopts a hoist chain to connect the opening and closing plates, and the hoist chain has a large breaking force, which can improve the reliability of the use of the slag bucket.

[0006] Furthermore, in order to ensure the structural strength and facilitate the control of the opening and closing plate, the opening and closing plate includes an opening and closing steel plate, two connecting plates, and a hanging plate. The hanging plate is arranged along the longitudinal direction of the opening and closing steel plate and welded to the outer side surface of the opening and closing steel plate. Both ends of the hanging plate extend to the outer side of the opening and closing steel plate, and both ends of the hanging plate are provided with hanging ears; the two connecting plates are arranged at intervals along the transverse direction of the opening and closing steel plate and welded to the outer side surface of the opening and closing steel plate, one end of the connecting plate is welded to the side surface of the hanging plate, and the other end of the connecting plate extends to the outer side of the opening and closing steel plate, and the end of the connecting plate extending to the outer side of the opening and closing steel plate is provided with a hinge ear.

DETAILED DESCRIPTION

[0017] The present invention is further described below by way of non-limiting embodiments and in conjunction with the accompanying drawings:

[0018] As shown in the attached drawings, an automatic opening and closing slag bucket includes a slag bucket body 1, which is a rectangular parallelepiped structure welded from steel plates. The upper and lower parts of the slag bucket body 1 are open structures, and the bottom of the slag bucket body 1 is a slag discharge port. Two of the opposite side walls of the slag bucket body 1 at the slag discharge port are respectively hingedly connected with an opening and closing plate 4, and the two opening and closing plates 4 can be closed when they are closed. Hydraulic cylinders 2 are respectively arranged on the upper parts of the other two opposite side walls of the slag bucket body 1, and the piston rod ends of the hydraulic cylinders 2 on each side are connected with two hoist chains 3, and the two hoist chains 3 are respectively connected to the ends of the two opening and closing plates 4 on this side. The hydraulic cylinder in the utility model adopts an electric hydraulic cylinder, which is a prior art. A motor for driving the hydraulic cylinder and a battery for powering the motor are arranged on the slag bucket body 1. In order to ensure the safety of the equipment, a hydraulic cylinder protective cover 5 is arranged on the top of the hydraulic cylinder 2, a battery protective cover 6 is arranged on the outside of the battery, and a motor protective cover 7 is arranged on the outside of the motor.

[0019] In this embodiment, the structure adopted by the opening and closing plate 4 is: it includes an opening and closing steel plate 4-1, two connecting plates 4-2, and a hanging plate 4-3. The hanging plate 4-3 is arranged along the longitudinal direction of the opening and closing steel plate 4-1 and is close to the free end of the opening and closing steel plate 4-1. The hanging plate 4-3 is welded to the outer side surface of the opening and closing steel plate. The two ends of the hanging plate 4-3 extend to the outside of the opening and closing steel plate 4-1, and both ends of the hanging plate 4-3 are provided with lifting ears 4-5. The opening and closing plate 4 is connected to the hoist chain 3 on the corresponding side through the lifting ears 4-5 at both ends of the hanging plate 4-3. Two connecting plates 4-2 are arranged at intervals along the transverse direction of the opening and closing steel plate 4-1, and the two connecting plates 4-2 are welded to the outer side of the opening and closing steel plate 4-1. One end of the connecting plate 4-2 is welded to the side of the hanging plate 4-3, and the other end of the connecting plate 4-2 extends to the outside of the opening and closing steel plate 4-1. The end of the connecting plate 4-2 extending to the outside of the opening and closing steel plate 4-1 is provided with a hinge ear 4-4. The opening and closing plate 4 is connected to the hinge seat arranged on the hopper body 1 through the hinge ears 4-4 on the two connecting plates 4-2 through the pin shaft 8, and the opening and closing plate 4 can rotate around the pin shaft.

[0020] In order to ensure the load-bearing capacity of the slag bucket, the diameter of the hoist chain 3 in the present invention is preferably φ16mm. Compared with the wire rope, the breaking force of the hoist chain is greater, which can meet the load-bearing requirements of the slag bucket and ensure the working reliability of the slag bucket.

[0021] When the utility model is working, the piston rods of the hydraulic cylinders 2 on both sides are extended or retracted, and the hoist chain 3 can drive the two opening and closing plates 4 to rotate around their respective hinge points at the same time, so as to realize the opening or closing of the slag discharge port at the bottom of the slag bucket. When the two opening and closing plates 4 are opened, the slag in the slag bucket is discharged from the bottom. The hydraulic cylinder can be controlled by the electric control device, so that the slag bucket can remotely and manually control the slag discharge port switch, which can reduce construction risks, improve construction safety, and also improve construction efficiency, which is conducive to speeding up construction progress. The electric control device in the utility model adopts existing technology.
