Description

Technical Field

[0001] The utility model relates to the field of construction machinery, in particular to an integrated double winch assembly for underground continuous wall grabs. Background Art

[0002] Underground continuous wall construction technology has been widely used in modern infrastructure construction. This type of equipment usually installs a mast system on a crawler chassis with a control room. A crane mechanism is installed on the top of the mast system, and a power lifting mechanism is also installed on the crawler chassis. A steel wire rope is passed through the crane mechanism to connect a working mechanism and a pulley mechanism is used to increase the lifting capacity. The pulley mechanism has a complex structure and high manufacturing cost. The so-called power lifting mechanism generally uses a winch. This type of equipment has problems such as high cost and poor reliability during application.

[0003] The existing structure is that the tower lifting mechanism and the double winch mechanism are respectively installed at different joints on the upper chassis frame; when the whole machine is transported during transfer, the arrangement of the double winches causes the transportation height of the whole machine to be too high, and the double winches need to be disassembled, which makes the transfer of the whole machine inconvenient.

[0004] To solve the above problems, people consider using double winches. However, due to the use of double winches, the two wire ropes will inevitably encounter the problem of unbalanced tension, which will cause the working mechanism to shake and affect construction safety; and the two winches are inconvenient to disassemble and assemble when in use. Summary of the invention

[0005] The utility model aims to overcome the defects of the prior art and provide an integrated double winch assembly for an underground continuous wall grab, so as to solve the problems of unbalanced force, inconvenient assembly and disassembly, and unstable operation.

[0006] In order to solve the above technical problems, the utility model is achieved as follows:

[0007] An integrated double winch assembly for an underground continuous wall grab comprises a crawler chassis with a control room, the upper part of which is connected to a mast system via a tower lifting device, a crane mechanism is arranged on the top of the mast system, a power lifting mechanism is also arranged on the crawler chassis, and a working mechanism is connected to the crane mechanism via a steel wire rope; the crawler chassis comprises an upper chassis and a lower chassis; it is characterized in that the power lifting mechanism comprises two winches integrated on a frame, which are arranged on the upper chassis.

[0008] The integrated double winch assembly for underground continuous wall grab is characterized in that the fulcrum of the tower lifting device is arranged on the frame of the winch.

[0009] The integrated double winch assembly for underground continuous wall grab is characterized in that the frame is located in the middle of the upper chassis.

[0010] The integrated double winch assembly for underground continuous wall grab is characterized in that the rotary shaft of the winch is fixed on the frame.

[0011] The integrated double winch assembly for underground continuous wall grab is characterized in that the frame and the upper chassis are connected via a connecting seat.

[0012] The integrated double winch assembly for underground continuous wall grab is characterized in that the upper part of the connecting seat is connected to the frame through two pins, and the lower part is arranged on the upper chassis in a trumpet shape to increase the force-bearing area and evenly bear the force.

[0013] The present application hides the double winches in the upper chassis and directly connects the tower lifting mechanism to the winch frame, thus saving height space and meeting the transportation conditions of the entire equipment without dismantling the winches, making the transfer of the entire equipment convenient.

[0014] The beneficial effects of the utility model are as follows: It can be seen from the above technical scheme that the present application provides an integrated double winch assembly for an underground continuous wall grab, which solves the problem of inconvenient disassembly and assembly by installing the double winches on the same frame; and by arranging the frame in the middle of the chassis, the force is balanced and the operation is stable.
