Grab bucket grooving machine for continuous wall

Abstract

The invention relates to the technical field of piling machinery, and discloses a grab bucket grooving machine for a continuous wall. The grab bucket grooving machine for the continuous wall comprises a chassis, an upper vehicle body arranged on the chassis, and an arm frame hinged on the upper vehicle body, wherein the arm frame comprises a fist part and a second part which are connected with each other, the first part has a box type structure, and the second part has a truss structure. The grab bucket grooving machine for the continuous wall provided by the embodiment of the invention has the functions of cranes, can work under a grooving operation mode, and also can work under a hoisting operation mode, so that the construction efficiency is improved, and the construction cost is lowered.

Description

technical field [0001] The invention relates to the technical field of pile machinery, in particular to a continuous wall grab groove forming machine. Background technique [0002] As a deep foundation construction equipment that can meet high-efficiency and high-quality construction, the underground diaphragm wall grab groover is widely used in the foundation construction of urban high-rise buildings, subways, basements, sewage treatment plants, oil and gas underground storage tanks, and dams Construction of various deep foundation projects such as retaining walls, seepage-proof walls, and foundation square piles. [0003] The off-road crane is widely used in the hoisting industry due to its advantages of large lifting capacity and the ability to lift and walk. It has the characteristics of good stability, good anti-skid performance, low requirements on the road surface, and slow driving speed. These characteristics are the same as the underground diaphragm wall grab. Slot...

AI Technical Summary

Problems solved by technology

[0005] On the surface, the hoisting operation can be realized by replacing the working device of the continuous wall grab bucket machine with a sling, but the inventor found in the process of realizing the present invention that due to the limitation of its own characteristics, the existing continuous wall The wall grab slotting machine cannot be directly used in the hoisting process. For example, the arm frames of some existing continuous wall grab slotting machines adopt a full box structure. Although the structural strength of the arm frame is effectively guaranteed, if it is used In the hoisting process, it is necessary to add a larger counterweight to the upper body, which increases the weight of the whole machine; the arm frames of other existing diaphragm wall grab groovers adopt a full truss structure, although it can effectively reduce the weight of the whole machine. machine weight, but if hoisting a large-tonnage grab bucket, its structural strength is difficult to be guaranteed

[0006] In addition, in the luffing mechanism of the existing diaphragm wall grab bucket forming machine, a quadrilateral structure is formed between the luffing support rod, the luffing cable, the arm frame and the upper car body, which is relatively unstable when the force is applied

[0007] In addition, the existing diaphragm wall grab groover usually uses a main winch, which cannot lift larger tonnage grabs or heavy objects

[0008] In addition, in the existing diaphragm wall grab groove forming machine, a spring push rod is usually arranged between the boom and the upper body to reduce the rebound amplitude of the boom, but the rebound of the spring push rod after energy absorption The effect will also affect the reset of the boom
