Description

Technical Field

[0001] This utility model relates to the field of grab bucket technology for trenching construction of diaphragm walls, and in particular to a grab bucket for trenching construction of diaphragm walls. Background Technology

[0002] With the development of the times, people are using various types of buildings more and more widely. Underground continuous walls are a type of continuous wall structure formed by excavating and pouring concrete in sections along the perimeter axis of a deep excavation project under the condition of mud wall protection. Therefore, it is necessary to use a grab bucket for trenching construction.

[0003] To address this, patent CN211973617U discloses a hydraulic grab bucket for a trenching machine used in the construction of diaphragm walls. It includes an arc-shaped plate and two side plates fixed to both sides of the arc-shaped plate. The arc-shaped plate has elongated through holes, and the side plates have circular through holes. Each elongated through hole is detachably connected to a baffle strip for blocking most of its area. The circular through holes are detachably connected to plugs. This hydraulic grab bucket can effectively relieve pressure during the excavation process while maintaining high clearance efficiency.

[0004] The aforementioned trenching grab buckets are inefficient and inconvenient to install and use, thus limiting their application. Utility Model Content

[0005] The purpose of this utility model is to provide a grab bucket for excavating trenches in diaphragm walls, in order to solve the defects of existing grab buckets for excavating trenches in diaphragm walls that are inefficient and inconvenient to install and position.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a grab bucket for excavation of underground continuous wall, including an installation column and a connecting column;

[0007] The top of the mounting column is uniformly fixed with connecting columns, and the bottom of the mounting column is uniformly hinged with a grooved structure.

[0008] The trenching structure includes a grab bucket body hinged to the bottom of the mounting column. A reserved slot is provided on one side of the grab bucket body, and a hydraulic push rod is provided inside the reserved slot. Mounting slots are provided on both sides of the mounting column on one side of the grab bucket body.

[0009] An installation structure is fixed to the top of the connecting column.

[0010] Preferably, the grab bucket body is symmetrically distributed at the bottom of the mounting column, and the hydraulic push rod is rotatably connected to one side of the grab bucket body inside the reserved slot.

[0011] Preferably, the mounting grooves are symmetrically distributed on both sides of the connecting column, and the connecting columns are evenly spaced at the top of the mounting column.

[0012] Preferably, one side of the hydraulic push rod is disposed inside the mounting groove, and the mounting groove is rotatably connected to the hydraulic push rod.

[0013] Preferably, the mounting structure includes a mounting plate fixed to the top of the connecting column, the mounting plate having threaded holes evenly distributed inside, each threaded hole having a mounting bolt inside, and the mounting bolt having a washer on its outer wall.

[0014] Preferably, the threaded holes are evenly spaced inside the mounting plate, and the top of the gasket abuts against the bottom of the mounting plate.

[0015] Preferably, all the mounting bolts are threadedly connected to the threaded holes.

[0016] The grab bucket for trenching construction of underground continuous wall provided by this utility model has the following advantages:

[0017] By setting a grooving structure, one side of the hydraulic push rod is placed inside the mounting groove and forms a threaded connection with it, while the side away from the mounting column is placed inside the mounting groove and forms a threaded connection with the grab bucket body. This makes it easy to push the grab bucket body by activating the hydraulic push rod. One side of the hydraulic push rod is rotatably connected to the bottom of the mounting column, thereby facilitating the grooving process of the device through the mounting plate.

[0018] By incorporating an installation structure, the mounting bolts are threadedly connected to the threaded holes, and washers are used to prevent the mounting bolts from coming loose during use. Furthermore, multiple sets of mounting bolts are provided to enhance the installation and positioning effect, thereby facilitating the installation of the device and achieving the goal of making the trenching device easy to install and preventing it from falling off.
