Embodiment Construction

[0028] The present invention will be further described below in conjunction with specific embodiments.

[0029] Such as Figure 1-12 As shown, a super-large-tonnage hydraulic excavator integrally assembled power cabin includes a power cabin 41, a power cabin frame 39 is arranged on the power cabin 41, and the power cabin frame 39 is detachably fixed on the rotary platform 40. The power cabin frame 39 It is assembled from the base of the power cabin 1, six columns 2, four short beams 5 and two long beams 6, and the connected columns 2, short beams 5 and long beams 6 are respectively connected by first bolts 3 It is connected with the first gasket 4 and then fixed on the power cabin base 1 as a whole to form an integrally assembled power cabin frame 39. When making, first assemble small pieces of each column 2, short beam 5 and long beam 6. Spot, welding, vibration aging after welding, release welding stress, prevent welding deformation after machining, and finally perform post...

Abstract

The present invention is an integrally assembled power cabin of a super large tonnage hydraulic excavator, comprising a power cabin frame, the power cabin frame is assembled from a power cabin base, upright columns, short beams and long beams, a partition plate is arranged in the power cabin frame and Divided into two working rooms, the top of the power cabin frame is provided with a top sealing plate, the left side is provided with a pump room passage, and there are multiple inspection doors on the power cabin frame. The present invention provides an integrally assembled power cabin for a super-large tonnage hydraulic excavator. The power components are uniformly placed in the frame of the power cabin to realize separate packaging and shipping of the power components. Compared with the welded power cabin, the power cabin frame The key mounting surfaces and mounting holes of each component are processed by post-welding machining, the precision is easy to guarantee, and the assembly accuracy and efficiency are high. During assembly, the power components are preferentially installed on the base of the power cabin. The lifting height is low and the installation space is large. The frame of the power cabin passes through The positioning pin is installed on the slewing platform, and the top of the positioning pin is wedge-shaped to realize one-time accurate positioning.

Description

technical field [0001] The invention belongs to the technical field of hydraulic excavator power cabins, and in particular relates to an integrally assembled power cabin of a super-large-tonnage hydraulic excavator. Background technique [0002] At present, in the mining of various large-scale open-pit mines, large-scale infrastructure construction, and large-scale projects such as land reclamation projects and harbor river dredging, super-large tonnage hydraulic excavators are widely used because of their advantages of flexibility and high efficiency. [0003] The super-large tonnage hydraulic excavator is mainly composed of a dismounted traveling device, a slewing platform, a working device, a power device and other components. Excavation and loading operations. During the installation and transportation of super large tonnage hydraulic excavators, due to the relatively large size and weight of each component, it is difficult to ship the whole machine. After assembly and...
