Description

Technical Field

[0001] The utility model relates to the technical field of pipeline construction, and particularly relates to a liftable hopper applicable to an earthwork transfer station in a tunnel. Background Art

[0002] During the tunnel construction process, the excavation, transportation, and handling of earthwork are crucial links. To improve construction efficiency, an earthwork transfer station is usually set up in the tunnel for temporarily storing and transporting the excavated earthwork materials. In the earthwork transfer station, the lift is one of the key devices, and its design and function directly affect the efficiency of earthwork handling and the construction progress.

[0003] There are some obvious problems in the existing tunnel construction hoppers during actual use, mainly including the following points: (1) Low fault tolerance: In an environment with limited working space such as a tunnel, when the transfer station lifts the hopper, frequent position adjustment is required, which increases the construction complexity and time cost, thus affecting the efficiency of earthwork handling. (2) Low loading and unloading efficiency: Due to the lack of flexibility in design, the traditional hopper has a small loading capacity and is not easy to dump, resulting in a low unloading efficiency. (3) Difficult to clean: If there are dead corners in the hopper, the silt in the dead corners cannot be poured out when the earthwork is dumped, reducing the earthwork transportation efficiency. Content of the Utility Model

[0004] Aiming at the above deficiencies of the prior art, the utility model provides a liftable hopper applicable to an earthwork transfer station in a tunnel.

[0005] The technical solution adopted by the utility model to achieve the above purpose is: A liftable hopper applicable to an earthwork transfer station in a tunnel, characterized in that it includes a hopper body surrounded by connecting a panel and a web. The top surface of the hopper body is an open structure. It also includes bevel structures at the four corners of the bottom of the hopper body. The bevel structures are arranged along the length direction of the hopper body. The outside of the hopper body is covered with reinforcing ribs. The reinforcing ribs are continuous in the horizontal direction and discontinuous in the vertical direction. The bottom ends of the vertical reinforcing ribs extending into the bevel structures are connected to a lifting plate for the lift to lift the hopper. Symmetrical positions at both ends of the lifting plate are jack lifting areas. Vertical plates are symmetrically arranged in the jack lifting areas. The vertical plates are connected between the lifting plate and the hopper body. Two lifting lugs are connected up and down on both sides of the head and tail of the hopper body. The upper lifting lug is used for the hopper to be lifted by a crane, and the lower lifting lug is used for the auxiliary hook of the crane to lift simultaneously to turn over the fully loaded hopper.

[0006] The hopper body is 3300mm long, 1750mm wide, and 1300mm high. The inner wall uses 5mm thick steel plates, and the reinforcing ribs adopt L63*40*5 angle steel.

[0007] The webs are angle-connected, and the panel is cut off at the head and then butt-connected at the back.

[0008] The lifting plate is a long strip plate with a thickness of 10 mm, and the lifting lug is made of a round steel with a diameter of 100 mm.

[0009] The jack lifting area is marked in red.

[0010] The beneficial effects of the present utility model are as follows:

[0011] (1) Strong fault tolerance: It is compatible with normal lifting even when the car parking position is inaccurate. Cooperating with the automatic control system will significantly improve the efficiency and safety of earthwork treatment.

[0012] (2) Large-capacity design: On the premise of ensuring the structural strength, the new hopper has a large design capacity, which increases the amount of earthwork loaded each time, reduces the loading times, and improves the construction efficiency.

[0013] (3) Low cost: The hopper is made of plates and profiles, with low material and processing costs, and has economy. The design is simple, the manufacturing process is mature, and it is easy to mass-produce and maintain.

[0014] (4) Easy to clean: The inside of the hopper has a dead-angle-free design, enabling the earthwork and muck to be dumped smoothly, reducing the accumulation of residues, facilitating cleaning and maintenance, and ensuring the long-term efficient operation of the equipment.

[0015] (5) Safe and reliable: The hopper has good stability during the lifting and adjustment processes, preventing overturning and collision, and ensuring the safety of construction personnel and equipment. It adapts to the changing needs of tunnel construction and provides reliable technical support for tunnel projects. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] As Figure 1As shown in the figure, a liftable hopper applicable to the earthwork transfer station in the tunnel includes a hopper body 1 formed by enclosing a panel and a web. The top surface of the hopper body 1 is an open structure. It also includes a chamfer structure 2 at the four corners of the bottom of the hopper body 1. The chamfer structure 2 is arranged along the length direction of the hopper body 1. The outer side of the hopper body 1 is coated with reinforcing ribs 3. The reinforcing ribs 3 are continuous in the horizontal direction and discontinuous in the vertical direction. The bottom ends of the vertical reinforcing ribs extending into the chamfer structure 2 are connected to a lifting plate 4 for the lifter to lift the hopper. The two symmetric positions at both ends of the lifting plate 4 are jack lifting areas 5. Vertical plates 6 are symmetrically arranged in the jack lifting areas 5. The vertical plates 6 are connected between the lifting plate 4 and the hopper body 1. Two lifting lugs are connected up and down on both sides of the head and tail of the hopper body 1. The upper lifting lug 7 is used for the hopper to be lifted by a crane, and the lower lifting lug 8 is used for the auxiliary hook of the crane to lift simultaneously to turn the fully loaded hopper.

[0021] The hopper body 1 is 3300mm long, 1750mm wide and 1300mm high. The inner wall uses 5mm thick steel plate, and the reinforcing ribs 3 adopt L63*40*5 angle steel.

[0022] The webs are angle-connected, and the panel is butted after cutting off the rear side of the head.

[0023] The lifting plate 4 is a 10mm thick long strip plate, and the lifting lug is made of a round steel with a diameter of 100mm.

[0024] The jack lifting area 5 is painted with a red mark.

[0025] As Figure 3 shown in the figure, when the utility model is applied, it needs to go through two working stations: lifting by a lifter and jacking by a jack. The lifter 9 lifts the lifting plate 4. Since the lifting plate is in the chamfer structure 2, the chamfer structure 2 and the side wall of the hopper form a triangle, making the force sufficient and stable during lifting. The vertical plates 6 arranged in the jack lifting area 5 make the force evenly distributed when the jack 10 jacks up.
